NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION
Corporate Structure
DTE Energy owns the following businesses:
•DTE Electric is a public utility engaged in the generation, purchase, distribution, and sale of electricity to approximately 2.2 million customers in southeastern Michigan;
•DTE Gas is a public utility engaged in the purchase, storage, transportation, distribution, and sale of natural gas to approximately 1.3 million customers throughout Michigan and the sale of storage and transportation capacity; and
•Other businesses primarily involved in 1) services related to the gathering, transportation, and storage of natural gas; 2) power and industrial projects; and 3) energy marketing and trading operations.
DTE Electric and DTE Gas are regulated by the MPSC. Certain activities of DTE Electric and DTE Gas, as well as various other aspects of businesses under DTE Energy, are regulated by the FERC. In addition, the Registrants are regulated by other federal and state regulatory agencies including the NRC, the EPA, EGLE, and for DTE Energy, the CFTC and CARB.
Basis of Presentation
The Consolidated Financial Statements should be read in conjunction with the Combined Notes to Consolidated Financial Statements included in the combined DTE Energy and DTE Electric 2020 Annual Report on Form 10-K.
The accompanying Consolidated Financial Statements of the Registrants are prepared using accounting principles generally accepted in the United States of America. These accounting principles require management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from the Registrants' estimates.

DTE Energy Company - DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
The Consolidated Financial Statements are unaudited but, in the Registrants' opinions, include all adjustments necessary to present a fair statement of the results for the interim periods. All adjustments are of a normal recurring nature, except as otherwise disclosed in these Consolidated Financial Statements and Combined Notes to Consolidated Financial Statements. Financial results for this interim period are not necessarily indicative of results that may be expected for any other interim period or for the fiscal year ending December 31, 2021.
The information in these combined notes relates to each of the Registrants as noted in the Index of Combined Notes to Consolidated Financial Statements. However, DTE Electric does not make any representation as to information related solely to DTE Energy or the subsidiaries of DTE Energy other than itself.
On July 1, 2021, DTE Energy completed the previously announced separation of its natural gas pipeline, storage and gathering non-utility business. Effective with the separation, DTE retains no ownership in the new company, DT Midstream. The Consolidated Financial Statements and Combined Notes to Consolidated Financial Statements included herein are prior to the separation and all results as of and for the period ended June 30, 2021 include that of DT Midstream. Historical results of DT Midstream, which is primarily comprised of the Gas Storage and Pipelines segment and also includes certain DTE Energy holding company activity within the Corporate and Other segment, will be presented as discontinued operations beginning in the third quarter 2021. Any impacts to DTE Energy tax attributes will also be reflected in the third quarter financial statements. Refer to Note 4 to the Consolidated Financial Statements, 'Dispositions and Impairments,' for additional information.
Principles of Consolidation
The Registrants consolidate all majority-owned subsidiaries and investments in entities in which they have controlling influence. Non-majority owned investments are accounted for using the equity method when the Registrants are able to significantly influence the operating policies of the investee. When the Registrants do not influence the operating policies of an investee, the equity investment is valued at cost minus any impairments, if applicable. These Consolidated Financial Statements also reflect the Registrants' proportionate interests in certain jointly-owned utility plants. The Registrants eliminate all intercompany balances and transactions.
The Registrants evaluate whether an entity is a VIE whenever reconsideration events occur. The Registrants consolidate VIEs for which they are the primary beneficiary. If a Registrant is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When assessing the determination of the primary beneficiary, a Registrant considers all relevant facts and circumstances, including: the power, through voting or similar rights, to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to receive the expected returns of the VIE. The Registrants perform ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.
Legal entities within DTE Energy's Power and Industrial Projects segment enter into long-term contractual arrangements with customers to supply energy-related products or services. The entities are generally designed to pass-through the commodity risk associated with these contracts to the customers, with DTE Energy retaining operational and customer default risk. These entities generally are VIEs and consolidated when DTE Energy is the primary beneficiary. In addition, DTE Energy has interests in certain VIEs through which control of all significant activities is shared with partners, and therefore are generally accounted for under the equity method.
Through June 30, 2021, DTE Energy owned an 85% interest in SGG, which owns and operates midstream natural gas assets. SGG has contracts through which certain construction risk was designed to pass-through to the customers, with DTE Energy retaining operational and customer default risk. SGG is a VIE with DTE Energy as the primary beneficiary.
The Registrants have variable interests in NEXUS, which include DTE Energy's 50% ownership interest through DT Midstream and DTE Electric's transportation services contract. NEXUS is a joint venture which owns a 256-mile pipeline to transport Utica and Marcellus shale gas to Ohio, Michigan, and Ontario market centers. NEXUS also owns Generation Pipeline, LLC, a 25-mile regulated pipeline system located in northern Ohio. NEXUS is a VIE as it has insufficient equity at risk to finance its activities. The Registrants are not the primary beneficiaries, as the power to direct significant activities is shared between the owners of the equity interests. DTE Energy accounts for its ownership interest in NEXUS under the equity method.
The Registrants hold ownership interests in certain limited partnerships. The limited partnerships include investment funds which support regional development and economic growth, and an operational business providing energy-related products. These entities are generally VIEs as a result of certain characteristics of the limited partnership voting rights. The ownership interests are accounted for under the equity method as the Registrants are not the primary beneficiaries.

Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
DTE Energy has variable interests in VIEs through certain of its long-term purchase and sale contracts. DTE Electric has variable interests in VIEs through certain of its long-term purchase contracts, including the transportation services contract with NEXUS. As of June 30, 2021, the carrying amount of assets and liabilities in DTE Energy's Consolidated Statements of Financial Position that relate to its variable interests under long-term purchase and sale contracts are predominantly related to working capital accounts and generally represent the amounts owed by or to DTE Energy for the deliveries associated with the current billing cycle under the contracts. As of June 30, 2021, the carrying amount of assets and liabilities in DTE Electric's Consolidated Statements of Financial Position that relate to its variable interests under long-term purchase contracts are predominantly related to working capital accounts and generally represent the amounts owed by DTE Electric for the deliveries associated with the current billing cycle under the contracts. The Registrants have not provided any significant form of financial support associated with these long-term contracts. There is no material potential exposure to loss as a result of DTE Energy's variable interests through these long-term purchase and sale contracts. In addition, there is no material potential exposure to loss as a result of DTE Electric's variable interests through these long-term purchase contracts.
The maximum risk exposure for consolidated VIEs is reflected on the Registrants' Consolidated Statements of Financial Position and, for DTE Energy, in Note 13 to the Consolidated Financial Statements, 'Commitments and Contingencies,' related to REF guarantees and indemnities. For non-consolidated VIEs, the maximum risk exposure of the Registrants is generally limited to their investment, notes receivable, future funding commitments, and amounts which DTE Energy has guaranteed.
The following table summarizes the major Consolidated Statements of Financial Position items for consolidated VIEs as of June 30, 2021 and December 31, 2020. All assets and liabilities of a consolidated VIE are presented where it has been determined that a consolidated VIE has either (1) assets that can be used only to settle obligations of the VIE or (2) liabilities for which creditors do not have recourse to the general credit of the primary beneficiary. VIEs, in which DTE Energy holds a majority voting interest and is the primary beneficiary, that meet the definition of a business and whose assets can be used for purposes other than the settlement of the VIE's obligations have been excluded from the table below.

Changes in Accumulated Other Comprehensive Income (Loss)
Comprehensive income (loss) is the change in common shareholders' equity during a period from transactions and events from non-owner sources, including Net Income. The amounts recorded to Accumulated other comprehensive income (loss) for DTE Energy include changes in benefit obligations, consisting of deferred actuarial losses and prior service costs, unrealized gains and losses from derivatives accounted for as cash flow hedges, and foreign currency translation adjustments. DTE Energy releases income tax effects from accumulated other comprehensive income when the circumstances upon which they are premised cease to exist.
Changes in Accumulated other comprehensive income (loss) are presented in DTE Energy's Consolidated Statements of Changes in Equity and DTE Electric's Consolidated Statements of Changes in Shareholder's Equity. For the three and six months ended months ended June 30, 2021 and 2020, reclassifications out of Accumulated other comprehensive income (loss) were not material.

Income Taxes
The interim effective tax rates of the Registrants are as follows:
Effective Tax Rate
Three Months Ended June 30, Six Months Ended June 30,
2021 2020 2021 2020
DTE Energy 11 % 2 % 8 % 8 %
DTE Electric 10 % 12 % 10 % 12 %
These tax rates are affected by estimated annual permanent items, including AFUDC equity, production tax credits, and other flow-through items, as well as discrete items that may occur in any given period, but are not consistent from period to period.
The 9% increase in DTE Energy's effective tax rate for the three months ended June 30, 2021 was primarily due to the 2020 carryback of 2018 net operating losses due to the CARES Act of 12% and West Virginia tax law change of 4% in 2021, partially offset by an increase in production tax credits of 4% and higher amortization of the TCJA regulatory liability of 3%. There was no change in DTE Energy's effective tax rate for the six months ended June 30, 2021 which included an increase in production tax credits of 3% and higher amortization of the TCJA regulatory liability of 3%, offset by the 2020 carryback of 2018 net operating losses due to the CARES Act of 5% and West Virginia tax law change of 1% in 2021.
The separation of DT Midstream on July 1, 2021 will impact DTE Energy's effective tax rate in future periods and adjustments will be incorporated beginning in the third quarter 2021.
The 2% decrease in DTE Electric's effective tax rate for the three and six months ended June 30, 2021 was primarily due to an increase in production tax credits of 1% and higher amortization of the TCJA regulatory liability of 1% in both periods.
DTE Electric had income tax receivables with DTE Energy of $2 million and $8 million at June 30, 2021 and December 31, 2020, respectively.
Unrecognized Compensation Costs
As of June 30, 2021, DTE Energy had $101 million of total unrecognized compensation cost related to non-vested stock incentive plan arrangements. That cost is expected to be recognized over a weighted-average period of 1.6 years.
Allocated Stock-Based Compensation
DTE Electric received an allocation of costs from DTE Energy associated with stock-based compensation of $11 million and $7 million for the three months ended June 30, 2021 and 2020, respectively, while such allocation was $25 million and $16 million for the six months ended June 30, 2021 and 2020, respectively.
Cash, Cash Equivalents, and Restricted Cash
Cash and cash equivalents include cash on hand, cash in banks, and temporary investments purchased with remaining maturities of three months or less. Restricted cash consists of funds held in separate bank accounts to satisfy contractual obligations and guarantee performance. Restricted cash designated for payments within one year is classified as a Current Asset.
Financing Receivables
Financing receivables are primarily composed of trade receivables, notes receivable, and unbilled revenue. The Registrants' financing receivables are stated at net realizable value.

DTE Energy Company - DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
The Registrants monitor the credit quality of their financing receivables on a regular basis by reviewing credit quality indicators and monitoring for trigger events, such as a credit rating downgrade or bankruptcy. Credit quality indicators include, but are not limited to, ratings by credit agencies where available, collection history, collateral, counterparty financial statements and other internal metrics. Utilizing such data, the Registrants have determined three internal grades of credit quality. Internal grade 1 includes financing receivables for counterparties where credit rating agencies have ranked the counterparty as investment grade. To the extent credit ratings are not available, the Registrants utilize other credit quality indicators to determine the level of risk associated with the financing receivable. Internal grade 1 may include financing receivables for counterparties for which credit rating agencies have ranked the counterparty as below investment grade; however, due to favorable information on other credit quality indicators, the Registrants have determined the risk level to be similar to that of an investment grade counterparty. Internal grade 2 includes financing receivables for counterparties with limited credit information and those with a higher risk profile based upon credit quality indicators. Internal grade 3 reflects financing receivables for which the counterparties have the greatest level of risk, including those in bankruptcy status.
The following represents the Registrants' financing receivables by year of origination, classified by internal grade of credit risk. The related credit quality indicators and risk ratings utilized to develop the internal grades have been updated through June 30, 2021.

The allowance for doubtful accounts on accounts receivable for the utility entities is generally calculated using an aging approach that utilizes rates developed in reserve studies. DTE Electric and DTE Gas establish an allowance for uncollectible accounts based on historical losses and management's assessment of existing and future economic conditions, customer trends and other factors. Customer accounts are generally considered delinquent if the amount billed is not received by the due date, which is typically in 21 days, however, factors such as assistance programs may delay aggressive action. DTE Electric and DTE Gas generally assess late payment fees on trade receivables based on past-due terms with customers. Customer accounts are written off when collection efforts have been exhausted. The time period for write-off is 150 days after service has been terminated.
The customer allowance for doubtful accounts for non-utility businesses and other receivables for both utility and non-utility businesses is generally calculated based on specific review of probable future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, customer trends and other factors are also considered. Receivables are written off on a specific identification basis and determined based upon the specific circumstances of the associated receivable.
Notes receivable for DTE Energy are primarily comprised of finance lease receivables and loans that are included in Notes Receivable and Other current assets on DTE Energy's Consolidated Statements of Financial Position. Notes receivable for DTE Electric are primarily comprised of loans.

Notes receivable are typically considered delinquent when payment is not received for periods ranging from 60 to 120 days. The Registrants cease accruing interest (nonaccrual status), consider a note receivable impaired, and establish an allowance for credit loss when it is probable that all principal and interest amounts due will not be collected in accordance with the contractual terms of the note receivable. In determining the allowance for credit losses for notes receivable, the Registrants consider the historical payment experience and other factors that are expected to have a specific impact on the counterparty's ability to pay including existing and future economic conditions.
DTE Energy's Gas Storage & Pipelines segment has an investment in certain assets in the Utica shale region which is accounted for as a note receivable. In the second quarter 2021, DTE Energy assessed the note receivable for impairment due to a reduction in forecasted volumes to be produced by the assets. As a result of fair value analysis, DTE Energy recorded a $19 million impairment of the note receivable, which is included in Asset (gains) losses and impairments, net on DTE Energy's Consolidated Statements of Operations for the three and six months ended June 30, 2021. Additionally, DTE Energy ceased accruing interest on the note receivable and reclassified the note to an Internal grade 3 receivable. There is no further risk of impairment to DTE Energy as the note receivable will transfer to DT Midstream upon its separation on July 1, 2021.
DTE Energy has off balance sheet exposure in the form of a revolving credit facility. Refer to Note 13, 'Commitments and Contingencies,' for additional information. In determining the level of credit reserve needed, DTE considers the likelihood of funding in addition to the other factors noted above. A reserve may be established when it is likely that funding will occur. Cash payments received on nonaccrual status notes receivable, that do not bring the account contractually current, are first applied to the contractually owed past due interest, with any remainder applied to principal. Accrual of interest is generally resumed when the note receivable becomes contractually current.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions, and clarifying certain requirements regarding franchise taxes, goodwill, consolidated tax expenses, and annual effective tax rate calculations. The Registrants adopted the ASU effective January 1, 2021 using the modified retrospective and prospective approaches, where applicable. The adoption of the ASU did not have a significant impact on the Registrants' Consolidated Financial Statements.
In August 2020, the FASB issued ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity. The amendments in this update simplify the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts indexed to and potentially settled in an entity's own equity. The Registrants adopted the ASU effective January 1, 2021 using the modified retrospective approach. The adoption of the ASU did not have a significant impact on the Registrants' Consolidated Financial Statements.
Recently Issued Pronouncements
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended. The amendments in this update provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance can be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The optional relief is temporary and cannot be applied to contract modifications and hedging relationships entered into or evaluated after December 31, 2022. The Registrants presently have various contracts that reference LIBOR and are assessing how this standard may be applied to specific contract modifications.
In July 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors - Certain Leases with Variable Lease Payments. The amendments in this update modify lease classification requirements for lessors, providing that lease contracts with variable lease payments that do not depend on a reference index or a rate should be classified as operating leases if they would have been classified as a sales-type or direct financing lease and resulted in the recognition of a selling loss at lease commencement. The ASU is effective for the Registrants for fiscal years beginning after December 15, 2021, and interim periods therein. Early adoption is permitted. The Registrants are currently assessing the impact of this standard on their Consolidated Financial Statements.

NOTE 4 - DISPOSITIONS AND IMPAIRMENTS
Separation of DT Midstream
On October 27, 2020, DTE Energy announced that its Board of Directors had authorized management to pursue a plan to spin-off its natural gas pipeline, storage and gathering non-utility business. On July 1, 2021, DTE Energy completed the separation of the new company, DT Midstream, through the distribution of 96,732,466 shares of DT Midstream common stock to DTE Energy shareholders. The distribution reflected 100% of the outstanding common stock of DT Midstream as of 5:00 p.m. ET on June 18, 2021 (the 'record date'). DTE Energy shareholders received one share of DT Midstream common stock for every two shares of DTE Energy common stock held at the close of business on the record date, with certain shareholders receiving cash in lieu of fractional shares of DT Midstream common stock. For U.S. federal income tax purposes, DTE Energy's U.S. shareholders generally should not recognize gain or loss as a result of the distribution of DT Midstream stock, except with respect to cash received in lieu of fractional shares.

In June 2021, in order to facilitate the separation and settle intercompany balances with DTE Energy, DT Midstream issued long-term debt in the form of $2.1 billion senior notes and a $1.0 billion term loan. Using the debt proceeds, net of discount and issuance costs of $53 million, DT Midstream made the following cash payments:
•Settled Short-term borrowings due to DTE Energy as of June 30, 2021 of $2,537 million
•Settled affiliate Accounts Receivable due from DTE Energy and affiliate Accounts payable due to DTE Energy as of June 30, 2021 for net cash paid to DTE Energy of $9 million
•Provided a one-time special dividend to DTE Energy of $501 million
These payments eliminated in consolidation and had no impact on DTE Energy's Consolidated Financial Statements of Financial Position for the period ended June 30, 2021. During July 2021, DTE Energy used the proceeds received from DT Midstream to optionally redeem $2.2 billion of long-term debt and provided notice of its intent to redeem an additional $374 million of long-term debt in August 2021. Refer to Note 10 to the Consolidated Financial Statements, 'Long-term Debt,' for additional information. Prior to the debt redemptions, the proceeds were held in a temporary investment account within the Corporate and Other segment and included in Cash and cash equivalents in the Consolidated Statements of Financial Position as of June 30, 2021.
Through June 30, 2021, DTE Energy has incurred $43 million of transaction costs associated with the separation of DT Midstream, including legal, accounting and other professional services fees. These transaction costs included $24 million and $34 million for the three and six months ended June 30, 2021, respectively, and were recorded in Operation and maintenance expense in DTE Energy's Consolidated Statements of Operations for the respective periods. DTE Energy expects additional transaction costs to be incurred in the third quarter in conjunction with the completed separation.
Following the separation on July 1, 2021, DT Midstream became an independent public company listed under the symbol 'DTM' on the New York Stock Exchange (NYSE) and DTE Energy no longer retains any ownership in DT Midstream. In order to govern the ongoing relationships between DT Midstream and DTE Energy after the separation and to facilitate an orderly transition, the parties entered into a series of agreements including the following:
•Separation and Distribution Agreement- sets forth the principal actions to be taken in connection with the separation, including the transfer of assets and assumption of liabilities, among others, and sets forth other agreements governing aspects of the relationship between DTE Energy and DT Midstream
•Transition Services Agreement- allows for DTE Energy to provide DT Midstream with specified services for a limited time and no longer than 24 months following the separation, including support for accounting, tax, legal, human resources, informational technology, and various other administrative and operational services
•Tax Matters Agreement- governs the respective rights, responsibilities and obligations of DTE Energy and DT Midstream after the separation with respect to all tax matters
•Employee Matters Agreement- addresses certain employment, compensation and benefits matters, including the allocation and treatment of certain assets and liabilities relating to DT Midstream employees
In addition, DTE Energy and its subsidiaries have various commercial agreements that will continue after the separation. These agreements include certain pipeline, gathering, and storage services and operating and maintenance agreements, and are not considered material to the Consolidated Financial Statements.
Power and Industrial Projects Segment Impairment
Power & Industrial Projects owns a pulverized coal facility located at DTE Electric's River Rouge power plant. The facility provides pulverized coal to a steel industry customer through a supply agreement expiring in 2028. The River Rouge plant provides operation and maintenance services to the facility through an agreement which also expires in 2028.
During the second quarter 2021, DTE Electric retired the River Rouge plant and provided an early termination notice of the operation and maintenance services agreement with the pulverized coal facility. The termination will be effective December 31, 2021, at which point Power and Industrial Projects will cease operations at the facility.

DTE Energy Company - DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
In connection with these events, DTE Energy performed an impairment analysis of the pulverized coal facility long-lived assets in accordance with ASC 360, Property, Plant and Equipment. Based on its undiscounted cash flow projections, DTE Energy determined that the carrying value of the pulverized coal facility asset group is not recoverable. As a result, DTE Energy recorded a non-cash impairment charge of $27 million, which is included in Asset (gains) losses and impairments, net on DTE Energy's Consolidated Statements of Operations for the three and six months ended June 30, 2021. The charge included $18 million to fully impair the long-lived assets recorded to Property, plant and equipment and a $9 million write-down of Other noncurrent assets to fair value. Fair value of the assets was determined using an income approach, which utilized assumptions including management's best estimates of the expected future cash flows, the estimated useful life of the asset group and discount rate.
There were no other adjustments deemed necessary as of June 30, 2021 related to the closure of the facility. DTE Energy is currently monitoring contract negotiations with the steel industry customer to determine any future impacts. An estimate of such impacts cannot be determined at this time as alternatives are currently being evaluated; however, the likelihood of any impact being material to DTE Energy's Consolidated Financial Statements is remote.

NOTE 6 - REGULATORY MATTERS
2020-2021 Accounting Applications
On July 9, 2020, the MPSC approved DTE Electric's request to accelerate amortization of the portion of its refundable federal income taxes regulatory liability related to non-plant accumulated deferred income tax balances that resulted from the TCJA. DTE Electric was authorized to increase amortization by $102 million beginning in May 2021, which would fully amortize this portion of the liability by the end of 2021 instead of April 2033. The accelerated amortization would not impact customer rates and would allow DTE Electric to defer its next rate case filing previously set for July 2020 to March 2021.
On February 26, 2021, DTE Electric filed an additional application requesting a delay in the accelerated amortization approved in the 2020 application. DTE Electric requested delaying the start of amortization from May 2021 to December 1, 2021, which would fully amortize these balances by the end of 2022 and allow DTE Electric to further defer its next rate case filing to October 2021 or later. The accounting application was approved by the MPSC on April 8, 2021.
2021 Securitization Filing
On March 26, 2021, DTE Electric filed an application requesting a financing order approving the securitization of $184 million of qualified costs related to the net book value of the River Rouge generation plant and tree trimming surge program costs. The filing requested collection of these qualifying costs from DTE Electric's customers.
A final MPSC order was issued on June 23, 2021 authorizing DTE Electric to proceed with the issuance of securitization bonds for qualified costs of up to $236 million, increased for the inclusion of deferred income taxes. The order authorized customer charges for the timely recovery of the amount securitized and other ongoing qualified costs. Securitization is expected in the fourth quarter 2021.
2021 Gas Rate Case Filing
DTE Gas filed a rate case with the MPSC on February 12, 2021 requesting an increase in base rates of $195 million based on a projected twelve-month period ending December 31, 2022. The requested increase in base rates is primarily due to an increase in net plant resulting from infrastructure investments and operating and maintenance expenses. The rate filing also requested an increase in return on equity from 9.9% to 10.25% and includes projected changes in sales and working capital. A final MPSC order in this case is expected by December 2021.

NOTE 7 - EARNINGS PER SHARE
Basic earnings per share is calculated by dividing net income, adjusted for income allocated to participating securities, by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the dilution that would occur if any potentially dilutive instruments were exercised or converted into common shares. DTE Energy's participating securities are restricted shares under the stock incentive program that contain rights to receive non-forfeitable dividends. Equity units and performance shares do not receive cash dividends; as such, these awards are not considered participating securities.

NOTE 8 - FAIR VALUE
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable inputs. The Registrants make certain assumptions they believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. Credit risk of the Registrants and their counterparties is incorporated in the valuation of assets and liabilities through the use of credit reserves, the impact of which was immaterial at June 30, 2021 and December 31, 2020. The Registrants believe they use valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.
A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be classified in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. The Registrants classify fair value balances based on the fair value hierarchy defined as follows:
•Level 1- Consists of unadjusted quoted prices in active markets for identical assets or liabilities that the Registrants have the ability to access as of the reporting date.
•Level 2- Consists of inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data.
•Level 3- Consists of unobservable inputs for assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost-benefit constraints.

(a)Amounts represent assets valued at NAV as a practical expedient for fair value.
Cash Equivalents
Cash equivalents include investments with maturities of three months or less when purchased. The cash equivalents shown in the fair value table are comprised of short-term investments and money market funds.
Nuclear Decommissioning Trusts and Other Investments
The nuclear decommissioning trusts and other investments hold debt and equity securities directly and indirectly through commingled funds. Exchange-traded debt and equity securities held directly, as well as publicly-traded commingled funds, are valued using quoted market prices in actively traded markets. Non-exchange traded fixed income securities are valued based upon quotations available from brokers or pricing services.
Non-publicly traded commingled funds holding exchange-traded equity or debt securities are valued based on stated NAVs. There are no significant restrictions for these funds and investments may be redeemed with 7 to 65 days notice depending on the fund. There is no intention to sell the investment in these commingled funds.
Private equity and other assets include a diversified group of funds that are classified as NAV assets. These funds primarily invest in limited partnerships, including private equity, private real estate and private credit. Distributions are received through the liquidation of the underlying fund assets over the life of the funds. There are generally no redemption rights. The limited partner must hold the fund for its life or find a third-party buyer, which may need to be approved by the general partner. The funds are established with varied contractual durations generally in the range of 7 years to 12 years. The fund life can often be extended by several years by the general partner, and further extended with the approval of the limited partners. Unfunded commitments related to these investments totaled $159 million and $183 million as of June 30, 2021 and December 31, 2020, respectively.
For pricing the nuclear decommissioning trusts and other investments, a primary price source is identified by asset type, class, or issue for each security. The trustee monitors prices supplied by pricing services and may use a supplemental price source or change the primary source of a given security if the trustee determines that another price source is considered preferable. The Registrants have obtained an understanding of how these prices are derived, including the nature and observability of the inputs used in deriving such prices.

Derivative Assets and Liabilities
Derivative assets and liabilities are comprised of physical and financial derivative contracts, including futures, forwards, options, and swaps that are both exchange-traded and over-the-counter traded contracts. Various inputs are used to value derivatives depending on the type of contract and availability of market data. Exchange-traded derivative contracts are valued using quoted prices in active markets. The Registrants consider the following criteria in determining whether a market is considered active: frequency in which pricing information is updated, variability in pricing between sources or over time, and the availability of public information. Other derivative contracts are valued based upon a variety of inputs including commodity market prices, broker quotes, interest rates, credit ratings, default rates, market-based seasonality, and basis differential factors. The Registrants monitor the prices that are supplied by brokers and pricing services and may use a supplemental price source or change the primary price source of an index if prices become unavailable or another price source is determined to be more representative of fair value. The Registrants have obtained an understanding of how these prices are derived. Additionally, the Registrants selectively corroborate the fair value of their transactions by comparison of market-based price sources. Mathematical valuation models are used for derivatives for which external market data is not readily observable, such as contracts which extend beyond the actively traded reporting period. The Registrants have established a Risk Management Committee whose responsibilities include directly or indirectly ensuring all valuation methods are applied in accordance with predefined policies. The development and maintenance of the Registrants' forward price curves has been assigned to DTE Energy's Risk Management Department, which is separate and distinct from the trading functions within DTE Energy.

The unobservable inputs used in the fair value measurement of the electricity and natural gas commodity types consist of inputs that are less observable due in part to lack of available broker quotes, supported by little, if any, market activity at the measurement date or are based on internally developed models. Certain basis prices (i.e., the difference in pricing between two locations) included in the valuation of natural gas and electricity contracts were deemed unobservable. The weighted average price for unobservable inputs was calculated using the average of forward price curves for natural gas and electricity and the absolute value of monthly volumes.
The inputs listed above would have had a direct impact on the fair values of the above security types if they were adjusted. A significant increase (decrease) in the basis price would have resulted in a higher (lower) fair value for long positions, with offsetting impacts to short positions.

Other Securities
At June 30, 2021 and December 31, 2020, the Registrants' securities included in Other investments on the Consolidated Statements of Financial Position were comprised primarily of investments within DTE Energy's rabbi trust. The rabbi trust was established to fund certain non-qualified pension benefits, and therefore changes in market value are recognized in earnings. Gains and losses are allocated from DTE Energy to DTE Electric and are included in Other Income or Other Expense, respectively, in the Registrants' Consolidated Statements of Operations.

NOTE 9 - FINANCIAL AND OTHER DERIVATIVE INSTRUMENTS
The Registrants recognize all derivatives at their fair value as Derivative assets or liabilities on their respective Consolidated Statements of Financial Position unless they qualify for certain scope exceptions, including the normal purchases and normal sales exception. Further, derivatives that qualify and are designated for hedge accounting are classified as either hedges of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge); or as hedges of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge). For cash flow hedges, the derivative gain or loss is deferred in Accumulated other comprehensive income (loss) and later reclassified into earnings when the underlying transaction occurs. For fair value hedges, changes in fair values for the derivative and hedged item are recognized in earnings each period. For derivatives that do not qualify or are not designated for hedge accounting, changes in fair value are recognized in earnings each period.
The Registrants' primary market risk exposure is associated with commodity prices, credit, and interest rates. The Registrants have risk management policies to monitor and manage market risks. The Registrants use derivative instruments to manage some of the exposure. DTE Energy uses derivative instruments for trading purposes in its Energy Trading segment. Contracts classified as derivative instruments include electricity, natural gas, oil, certain environmental contracts, forwards, futures, options, swaps, and foreign currency exchange contracts. Items not classified as derivatives include natural gas and environmental inventory, pipeline transportation contracts, certain environmental contracts, and natural gas storage assets.
DTE Electric- DTE Electric generates, purchases, distributes, and sells electricity. DTE Electric uses forward contracts to manage changes in the price of electricity and fuel. Substantially all of these contracts meet the normal purchases and normal sales exception and are therefore accounted for under the accrual method. Other derivative contracts are MTM and recoverable through the PSCR mechanism when settled. This results in the deferral of unrealized gains and losses as Regulatory assets or liabilities until realized.
DTE Gas - DTE Gas purchases, stores, transports, distributes, and sells natural gas, and buys and sells transportation and storage capacity. DTE Gas has fixed-priced contracts for portions of its expected natural gas supply requirements through March 2024. Substantially all of these contracts meet the normal purchases and normal sales exception and are therefore accounted for under the accrual method. Forward transportation and storage contracts are generally not derivatives and are therefore accounted for under the accrual method.
Gas Storage and Pipelines -This segment has been primarily engaged in services related to the gathering, transportation, and storage of natural gas. Primarily fixed-priced contracts have been used in the marketing and management of transportation and storage services. Generally, these contracts were not derivatives and were therefore accounted for under the accrual method. These contracts will not be retained by DTE Energy following the separation of DT Midstream on July 1, 2021.

DTE Energy Company - DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
Power and Industrial Projects- This segment manages and operates energy and pulverized coal projects, a coke battery, reduced emissions fuel projects, renewable gas recovery, and power generation assets. Primarily fixed-price contracts are used in the marketing and management of the segment assets. These contracts are generally not derivatives and are therefore accounted for under the accrual method.
Energy Trading - Commodity Price Risk -Energy Trading markets and trades electricity, natural gas physical products, and energy financial instruments, and provides energy and asset management services utilizing energy commodity derivative instruments. Forwards, futures, options, and swap agreements are used to manage exposure to the risk of market price and volume fluctuations in its operations. These derivatives are accounted for by recording changes in fair value to earnings unless hedge accounting criteria are met.
Energy Trading - Foreign Currency Exchange Risk -Energy Trading has foreign currency exchange forward contracts to economically hedge fixed Canadian dollar commitments existing under natural gas and power purchase and sale contracts and natural gas transportation contracts. Energy Trading enters into these contracts to mitigate price volatility with respect to fluctuations of the Canadian dollar relative to the U.S. dollar. These derivatives are accounted for by recording changes in fair value to earnings unless hedge accounting criteria are met.
Corporate and Other - Interest Rate Risk -DTE Energy may use interest rate swaps, treasury locks, and other derivatives to hedge the risk associated with interest rate market volatility.
Credit Risk -DTE Energy maintains credit policies that significantly minimize overall credit risk. These policies include an evaluation of potential customers' and counterparties' financial condition, including the viability of underlying productive assets, credit rating, collateral requirements, or other credit enhancements such as letters of credit or guarantees. DTE Energy generally uses standardized agreements that allow the netting of positive and negative transactions associated with a single counterparty. DTE Energy maintains a provision for credit losses based on factors surrounding the credit risk of its customers, historical trends, and other information. Based on DTE Energy's credit policies and its June 30, 2021 provision for credit losses, DTE Energy's exposure to counterparty nonperformance is not expected to have a material adverse effect on DTE Energy's Consolidated Financial Statements.
Derivative Activities
DTE Energy manages its MTM risk on a portfolio basis based upon the delivery period of its contracts and the individual components of the risks within each contract. Accordingly, it records and manages the energy purchase and sale obligations under its contracts in separate components based on the commodity (e.g. electricity or natural gas), the product (e.g. electricity for delivery during peak or off-peak hours), the delivery location (e.g. by region), the risk profile (e.g. forward or option), and the delivery period (e.g. by month and year). The following describes the categories of activities represented by their operating characteristics and key risks:
•Asset Optimization- Represents derivative activity associated with assets owned and contracted by DTE Energy, including forward natural gas purchases and sales, natural gas transportation, and storage capacity. Changes in the value of derivatives in this category typically economically offset changes in the value of underlying non-derivative positions, which do not qualify for fair value accounting. The difference in accounting treatment of derivatives in this category and the underlying non-derivative positions can result in significant earnings volatility.
•Marketing and Origination- Represents derivative activity transacted by originating substantially hedged positions with wholesale energy marketers, producers, end-users, utilities, retail aggregators, and alternative energy suppliers.
•Fundamentals Based Trading- Represents derivative activity transacted with the intent of taking a view, capturing market price changes, or putting capital at risk. This activity is speculative in nature as opposed to hedging an existing exposure.
•Other- Includes derivative activity at DTE Electric related to FTRs. Changes in the value of derivative contracts at DTE Electric are recorded as Derivative assets or liabilities, with an offset to Regulatory assets or liabilities as the settlement value of these contracts will be included in the PSCR mechanism when realized.

Certain of DTE Energy's derivative positions are subject to netting arrangements which provide for offsetting of asset and liability positions as well as related cash collateral. Such netting arrangements generally do not have restrictions. Under such netting arrangements, DTE Energy offsets the fair value of derivative instruments with cash collateral received or paid for those contracts executed with the same counterparty, which reduces DTE Energy's Total Assets and Liabilities. Cash collateral is allocated between the fair value of derivative instruments and customer accounts receivable and payable with the same counterparty on a pro-rata basis to the extent there is exposure. Any cash collateral remaining, after the exposure is netted to zero, is reflected in Accounts receivable and Accounts payable as collateral paid or received, respectively.
DTE Energy also provides and receives collateral in the form of letters of credit which can be offset against net Derivative assets and liabilities as well as Accounts receivable and payable. DTE Energy had issued letters of credit of $11 million and $7 million outstanding at June 30, 2021 and December 31, 2020, respectively, which could be used to offset net Derivative liabilities. Letters of credit received from third parties which could be used to offset net Derivative assets were $34 million and $9 million at June 30, 2021 and December 31, 2020, respectively. Such balances of letters of credit are excluded from the tables below and are not netted with the recognized assets and liabilities in DTE Energy's Consolidated Statements of Financial Position.
For contracts with certain clearing agents, the fair value of derivative instruments is netted against realized positions with the net balance reflected as either 1) a Derivative asset or liability or 2) an Account receivable or payable. Other than certain clearing agents, Accounts receivable and Accounts payable that are subject to netting arrangements have not been offset against the fair value of Derivative assets and liabilities.

Various subsidiaries of DTE Energy have entered into contracts which contain ratings triggers and are guaranteed by DTE Energy. These contracts contain provisions which allow the counterparties to require that DTE Energy post cash or letters of credit as collateral in the event that DTE Energy's credit rating is downgraded below investment grade. Certain of these provisions (known as 'hard triggers') state specific circumstances under which DTE Energy can be required to post collateral upon the occurrence of a credit downgrade, while other provisions (known as 'soft triggers') are not as specific. For contracts with soft triggers, it is difficult to estimate the amount of collateral which may be requested by counterparties and/or which DTE Energy may ultimately be required to post. The amount of such collateral which could be requested fluctuates based on commodity prices (primarily natural gas, power, environmental, and coal) and the provisions and maturities of the underlying transactions. As of June 30, 2021, DTE Energy's contractual obligation to post collateral in the form of cash or letters of credit in the event of a downgrade to below investment grade, under both hard trigger and soft trigger provisions, was $467 million.
As of June 30, 2021, DTE Energy had $969 million of derivatives in net liability positions, for which hard triggers exist. There is no collateral that has been posted against such liabilities, including cash and letters of credit. Associated derivative net asset positions for which contractual offset exists were $821 million. The net remaining amount of $148 million is derived from the $467 million noted above.

To early retire this debt and reduce future interest expense, DTE Energy incurred prepayment costs of $235 million in July 2021 and expects additional prepayment costs in conjunction with the planned redemptions in August 2021. Prepayment costs and any write-offs of unamortized issuance costs and discounts related to the retired debt will result in a loss on extinguishment of debt to be reflected in the Consolidated Statements of Operations for the third quarter 2021.

NOTE 11 - SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS
DTE Energy, DTE Electric, and DTE Gas have unsecured revolving credit agreements that can be used for general corporate borrowings, but are intended to provide liquidity support for each of the companies' commercial paper programs. Borrowings under the revolvers are available at prevailing short-term interest rates. DTE Energy also has other facilities to support letter of credit issuance.
The unsecured revolving credit agreements have historically required DTE Energy, DTE Electric, and DTE Gas to maintain a total funded debt to capitalization ratio of no more than 0.65 to 1. In the agreements, 'total funded debt' means all indebtedness of each respective company and their consolidated subsidiaries, including finance lease obligations, hedge agreements, and guarantees of third parties' debt, but excluding contingent obligations, nonrecourse and junior subordinated debt, and certain equity-linked securities and, except for calculations at the end of the second quarter, certain DTE Gas short-term debt. 'Capitalization' means the sum of (a) total funded debt plus (b) 'consolidated net worth,' which is equal to consolidated total equity of each respective company and their consolidated subsidiaries (excluding pension effects under certain FASB statements), as determined in accordance with accounting principles generally accepted in the United States of America. At June 30, 2021, the total funded debt to total capitalization ratios for DTE Energy, DTE Electric, and DTE Gas were 0.64 to 1, 0.53 to 1, and 0.47 to 1, respectively, and were in compliance with this financial covenant.
In June 2021, DTE Energy amended its total funded debt to capitalization ratio requirement to no more than 0.70 to 1 starting with the third quarter of 2021 and ending December 2022. The amendment was a result of temporary balance sheet impacts resulting from the separation of DT Midstream on July 1, 2021.
Additionally in June 2021, DT Midstream entered into a $750 million secured revolving credit agreement. Letter of credit issuances and borrowings under the agreement are primarily for the general corporate purposes of DT Midstream to support its future operations and liquidity. Financial covenants under the agreement will be effective for DT Midstream beginning in the third quarter 2021.
For DTE Energy, availability under the DT Midstream secured revolving credit agreement was limited to $33 million, including an $8 million letter of credit issuance in June 2021 and additional credit up to $25 million, of which no amounts were drawn as of June 30, 2021. The facility and its available credit will not be retained by DTE Energy following the separation of DT Midstream on July 1, 2021.

NOTE 13 - COMMITMENTS AND CONTINGENCIES
Environmental
DTE Electric
Air - DTE Electric is subject to the EPA ozone and fine particulate transport and acid rain regulations that limit power plant emissions of SO2and NOX. The EPA and the State of Michigan have also issued emission reduction regulations relating to ozone, fine particulate, regional haze, mercury, and other air pollution. These rules have led to controls on fossil-fueled power plants to reduce SO2, NOX, mercury, and other emissions. Additional rulemakings may occur over the next few years which could require additional controls for SO2, NOX, and other hazardous air pollutants.
The EPA proposed revised air quality standards for ground level ozone in November 2014 and specifically requested comments on the form and level of the ozone standards. The standards were finalized in October 2015. The State of Michigan recommended to the EPA in October 2016 which areas of the state are not attaining the new standard. On April 30, 2018, the EPA finalized the State of Michigan's recommended marginal non-attainment designation for southeast Michigan. The State is required to develop and implement a plan to address the southeast Michigan ozone non-attainment area by the end of 2021. The Registrants cannot predict the scope and associated financial impact of the State's plan to address the ozone non-attainment area at this time.

Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
The EPA has implemented regulatory actions under the Clean Air Act to address emissions of GHGs from the utility sector and other sectors of the economy. Among these actions, in 2015 the EPA finalized performance standards for emissions of carbon dioxide from new and existing fossil-fuel fired EGUs. The performance standards for existing EGUs, known as the EPA Clean Power Plan, were challenged by petitioners and stayed by the U.S. Supreme Court in February 2016 pending final review by the courts. On October 10, 2017, the EPA, under a new administration, proposed to rescind the Clean Power Plan, and in August 2018, the EPA proposed revised emission guidelines for GHGs from existing EGUs. On June 19, 2019, the EPA Administrator officially repealed the Clean Power Plan and finalized its replacement, named the ACE rule. The ACE rule was vacated and remanded back to the EPA in a D.C. Circuit Court decision on January 19, 2021. The next steps taken by the EPA with respect to regulation of GHGs from EGUs is uncertain. Regardless of future rules, DTE Energy remains committed for its electric utility operations to reduce carbon emissions 32% by 2023, 50% by 2030, and 80% by 2040 from 2005 carbon emissions levels, and its goal of net zero emissions for its electric utility operations by 2050.
In addition to the GHG standards for existing EGUs, in December 2018, the EPA issued proposed revisions to the carbon dioxide performance standards for new, modified, or reconstructed fossil-fuel fired EGUs. The carbon standards for new sources are not expected to have a material impact on DTE Electric, since DTE Electric has no plans to build new coal-fired generation and any potential new gas generation will be able to comply with the standards.
Pending or future legislation or other regulatory actions could have a material impact on DTE Electric's operations and financial position and the rates charged to its customers. Impacts include expenditures for environmental equipment beyond what is currently planned, financing costs related to additional capital expenditures, the purchase of emission credits from market sources, higher costs of purchased power, and the retirement of facilities where control equipment is not economical. DTE Electric would seek to recover these incremental costs through increased rates charged to its utility customers, as authorized by the MPSC.
To comply with air pollution requirements, DTE Electric has spent approximately $2.4 billion. DTE Electric does not anticipate additional capital expenditures for air pollution requirements through 2025, subject to the results of future rulemakings.
Water - In response to an EPA regulation, DTE Electric was required to examine alternatives for reducing the environmental impacts of the cooling water intake structures at several of its facilities. Based on the results of completed studies and expected future studies, DTE Electric may be required to install technologies to reduce the impacts of the water intake structures. A final rule became effective in October 2014. The final rule requires studies to be completed and submitted as part of the NPDES permit application process to determine the type of technology needed to reduce impacts to fish. DTE Electric has initiated the process of completing the required studies. Final compliance for the installation of any required technology will be determined by the state on a case by case, site specific basis. DTE Electric is currently evaluating the compliance options and working with the State of Michigan on evaluating whether any controls are needed. These evaluations/studies may require modifications to some existing intake structures. It is not possible to quantify the impact of this rulemaking at this time.
Contaminated and Other Sites - Prior to the construction of major interstate natural gas pipelines, gas for heating and other uses was manufactured locally from processes involving coal, coke, or oil. The facilities, which produced gas, have been designated as MGP sites. DTE Electric conducted remedial investigations at contaminated sites, including three former MGP sites. Cleanup of one of the MGP sites is complete, and the site is closed. The investigations have revealed contamination related to the by-products of gas manufacturing at each MGP site. In addition to the MGP sites, DTE Electric is also in the process of cleaning up other contaminated sites, including the area surrounding an ash landfill, electrical distribution substations, electric generating power plants, and underground and above ground storage tank locations. The findings of these investigations indicated that the estimated cost to remediate these sites is expected to be incurred over the next several years. At June 30, 2021 and December 31, 2020, DTE Electric had $10 million accrued for remediation. These costs are not discounted to their present value. Any change in assumptions, such as remediation techniques, nature and extent of contamination, and regulatory requirements, could impact the estimate of remedial action costs for the sites and affect DTE Electric's financial position and cash flows. DTE Electric believes the likelihood of a material change to the accrued amount is remote based on current knowledge of the conditions at each site.

Coal Combustion Residuals and Effluent Limitations Guidelines - A final EPA rule for the disposal of coal combustion residuals, commonly known as coal ash, became effective in October 2015, and was revised in October 2016, July 2018, September 2020, and November 2020. The rule is based on the continued listing of coal ash as a non-hazardous waste and relies on various self-implementation design and performance standards. DTE Electric owns and operates three permitted engineered coal ash storage facilities to dispose of coal ash from coal-fired power plants and operates a number of smaller impoundments at its power plants subject to certain provisions in the CCR rule. At certain facilities, the rule currently requires ongoing sampling and testing of monitoring wells, compliance with groundwater standards, and the closure of basins at the end of the useful life of the associated power plant.
On September 28, 2020, the CCR rule 'A Holistic Approach to Closure Part A: Deadline to Initiate Closure and Enhancing Public Access to Information' became effective and establishes April 11, 2021 as the new deadline for all unlined impoundments (including units previously classified as 'clay-lined') to initiate closure. Additionally, the rule amends certain reporting requirements and CCR website requirements. On November 12, 2020, an additional revision to the CCR Rule 'A Holistic Approach to Closure Part B: Alternate Demonstration for Unlined Surface Impoundments' was published in the Federal Register that provides a process to determine if certain unlined impoundments consist of an alternative liner system that may be as protective as the current liners specified in the CCR rule, and therefore may continue to operate. DTE Electric has submitted applications to the EPA that support continued use of all impoundments through their active lives. The forced closure date of April 11, 2021 is effectively delayed while the EPA's review looks to extend beyond this date.
At the State level, legislation was signed by the Governor in December 2018 and provides for further regulation of the CCR program in Michigan. Additionally, the bill provides the basis of a CCR program that EGLE has submitted to the EPA for approval to fully regulate the CCR program in Michigan in lieu of a Federal permit program.
In October 2020, the EPA published in the Federal Register the final version of the ELG Reconsideration Rule which updates the 2015 ELG Rule (2015 Rule). The Reconsideration Rule re-establishes the technology-based effluent limitations guidelines and standards applicable to flue gas desulfurization (FGD) wastewater and bottom ash transport water. The EPA set the applicability dates for bottom ash transport water and FGD wastewater retrofits to be 'as soon as possible' beginning October 13, 2021 and no later than December 31, 2025. Compliance schedules for individual facilities and individual waste streams are determined through issuance of new NPDES permits by the State of Michigan. The State of Michigan has issued a NPDES permit for the Belle River Power Plant establishing a compliance deadline of December 31, 2021 based on the 2015 Rule. Due to completion of the Reconsideration Rule in 2020, the compliance deadlines within the NPDES permit for Belle River Power Plant will be revised accordingly. No new permits that would require ELG compliance have been issued for other facilities, consequently no compliance timelines have been established.
On April 12, 2017, the EPA granted a petition for reconsideration of the 2015 ELG Rule. The EPA also signed an administrative stay of the 2015 ELG Rule's compliance deadlines for fly ash transport water, bottom ash transport water, and FGD wastewater, among others. On June 6, 2017, the EPA published in the Federal Register a proposed rule (Postponement Rule) to postpone certain applicable deadlines within the 2015 ELG rule. The Postponement Rule was published on September 18, 2017. The Postponement Rule nullified the administrative stay but also extended the earliest compliance deadlines for only FGD wastewater and bottom ash transport water until November 1, 2020 in order for the EPA to propose and finalize a new ruling. On October 13, 2020, the EPA finalized the ELG Reconsideration Rule which revised the regulations from the 2015 ELG rule. The Reconsideration Rule revises requirements for two specific waste streams produced by steam electric power plants: FGD wastewater and bottom ash transport water. The Reconsideration Rule also provides additional compliance opportunities by finalizing low utilization and cessation of coal burning subcategories. The Reconsideration Rule provides new opportunities for DTE Electric to evaluate existing ELG compliance strategies and make any necessary adjustments to ensure full compliance with the ELGs in a cost-effective manner.
DTE Electric is currently evaluating compliance strategies, technologies and system designs for both FGD wastewater and bottom ash transport water system to achieve compliance with the final rule.
DTE Electric has estimated the impact of the CCR and ELG rules to be $718 million of capital expenditures, including $573 million for 2021 through 2025.

DTE Gas
Air - In June 2020, DTE Energy expanded its net zero goal to include its gas utility operations by committing to reduce greenhouse gas emissions to net zero by 2050 from procurement of natural gas through delivery. As part of DTE Energy's 2050 net zero commitment, DTE Gas launched its CleanVision Natural Gas Balance program in January 2021 that offers customers a way to reduce their carbon footprint using carbon offsets and renewable natural gas. The carbon offset program is focused on protecting Michigan forests that naturally absorb carbon dioxide.
Contaminated and Other Sites - DTE Gas owns or previously owned 14 former MGP sites. Investigations have revealed contamination related to the by-products of gas manufacturing at each site. Cleanup of eight of the MGP sites is complete, and the sites are closed. DTE Gas has also completed partial closure of four additional sites. Cleanup activities associated with the remaining sites will continue over the next several years. The MPSC has established a cost deferral and rate recovery mechanism for investigation and remediation costs incurred at former MGP sites. In addition to the MGP sites, DTE Gas is also in the process of cleaning up other contaminated sites, including gate stations, gas pipeline releases, and underground storage tank locations. As of June 30, 2021 and December 31, 2020, DTE Gas had $23 million and $24 million, respectively, accrued for remediation. These costs are not discounted to their present value. Any change in assumptions, such as remediation techniques, nature and extent of contamination, and regulatory requirements, could impact the estimate of remedial action costs for the sites and affect DTE Gas' financial position and cash flows. DTE Gas anticipates the cost amortization methodology approved by the MPSC, which allows for amortization of the MGP costs over a ten-year period beginning with the year subsequent to the year the MGP costs were incurred, will prevent the associated investigation and remediation costs from having a material adverse impact on DTE Gas' results of operations.
Non-utility
DTE Energy's non-utility businesses are subject to a number of environmental laws and regulations dealing with the protection of the environment from various pollutants.
In March 2019, the EPA issued an FOV to EES Coke, the Michigan coke battery facility that is a wholly-owned subsidiary of DTE Energy, alleging that the 2008 and 2014 permits issued by EGLE did not comply with the Clean Air Act. In September 2020, the EPA issued another FOV alleging EES Coke's 2018 and 2019 SO2 emissions exceeded projections and hence violated non-attainment new source review requirements. EES Coke evaluated the EPA's alleged violations and believes that the permits approved by EGLE complied with the Clean Air Act. EES Coke also responded to the EPA's September 2020 allegations demonstrating its actual emissions are compliant with non-attainment new source review requirements. Discussions with the EPA are ongoing. At the present time, DTE Energy cannot predict the outcome or financial impact of this FOV.
Other
In 2010, the EPA finalized a new one-hour SO2ambient air quality standard that requires states to submit plans and associated timelines for non-attainment areas that demonstrate attainment with the new SO2standard in phases. Phase 1 addresses non-attainment areas designated based on ambient monitoring data. Phase 2 addresses non-attainment areas with large sources of SO2and modeled concentrations exceeding the National Ambient Air Quality Standards for SO2. Phase 3 addresses smaller sources of SO2with modeled or monitored exceedances of the new SO2standard.
Michigan's Phase 1 non-attainment area includes DTE Energy facilities in southwest Detroit and areas of Wayne County. Modeling runs by EGLE suggest that emission reductions may be required by significant sources of SO2emissions in these areas, including DTE Electric power plants and DTE Energy's Michigan coke battery facility. As part Michigan's SIP process, DTE Energy has worked with EGLE to develop air permits reflecting significant SO2emission reductions that, in combination with other non-DTE Energy sources' emission reduction strategies, will help the state attain the standard and sustain its attainment. The Michigan SIP was completed and submitted to the EPA on May 31, 2016 and supplemented on June 30, 2016. On March 19, 2021, the EPA published in the Federal Register partial approval and partial disapproval of Michigan's Detroit SO2 non-attainment area plan. The partial disapproval does not appear to impact DTE's sources and further discussions are underway with the EPA to finalize the plan. Since several non-DTE Energy sources are also part of the proposed compliance plan, DTE Energy is unable to determine the full impact of any further emissions reductions that may be required from DTE's facilities at this time.
Michigan's Phase 2 non-attainment area includes DTE Electric facilities in St. Clair County. EGLE has not made a final determination on SIP strategy for this area, pending the EPA's review of a clean data determination request. Until agency plans are final, DTE Energy is unable to determine the impacts.

Synthetic Fuel Guarantees
DTE Energy discontinued the operations of its synthetic fuel production facilities throughout the United States as of December 31, 2007. DTE Energy provided certain guarantees and indemnities in conjunction with the sales of interests in its synfuel facilities. The guarantees cover potential commercial, environmental, oil price, and tax-related obligations that will survive until 90 days after expiration of all applicable statutes of limitations. DTE Energy estimates that its maximum potential liability under these guarantees at June 30, 2021 was approximately $400 million. Payment under these guarantees is considered remote.
REF Guarantees
DTE Energy has provided certain guarantees and indemnities in conjunction with the sales of interests in or lease of its REF facilities. The guarantees cover potential commercial, environmental, and tax-related obligations that will survive until 90 days after expiration of all applicable statutes of limitations. DTE Energy estimates that its maximum potential liability under these guarantees at June 30, 2021 was $617 million. Payments under these guarantees are considered remote.
Other Guarantees
In certain limited circumstances, the Registrants enter into contractual guarantees. The Registrants may guarantee another entity's obligation in the event it fails to perform and may provide guarantees in certain indemnification agreements. Finally, the Registrants may provide indirect guarantees for the indebtedness of others. DTE Energy's guarantees are not individually material with maximum potential payments totaling $50 million at June 30, 2021. Payments under these guarantees are considered remote.
The Registrants are periodically required to obtain performance surety bonds in support of obligations to various governmental entities and other companies in connection with its operations. As of June 30, 2021, DTE Energy had $176 million of performance bonds outstanding, including $120 million for DTE Electric. In the event that such bonds are called for nonperformance, the Registrants would be obligated to reimburse the issuer of the performance bond. The Registrants are released from the performance bonds as the contractual performance is completed and does not believe that a material amount of any currently outstanding performance bonds will be called.
Vector Line of Credit
In July 2019, DTE Energy, as lender, entered into a revolving term credit facility with Vector, as borrower, in the amount of C$70 million. The credit facility was executed in response to the passage of Canadian regulations requiring oil and gas pipelines to demonstrate their financial ability to respond to a catastrophic event and exists for the sole purpose of satisfying these regulations. Vector may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payment under the line of credit at June 30, 2021 was $56 million. On July 7, 2021 and in conjunction with the separation of DT Midstream, DTE Energy transferred the credit facility to DT Midstream and DT Midstream assumed the lender role under the credit facility.
Labor Contracts
There are several bargaining units for DTE Energy subsidiaries' approximate 5,200 represented employees, including DTE Electric's approximately 2,700 represented employees. This represents 49% and 57% of DTE Energy's and DTE Electric's total employees, respectively. The majority of the represented employees are under contracts that expire in 2027.
Purchase Commitments
Utility capital expenditures, expenditures for non-utility businesses, and contributions to equity method investees will be approximately $3.9 billion and $3.0 billion in 2021 for DTE Energy and DTE Electric, respectively. The Registrants have made certain commitments in connection with the estimated 2021 annual capital expenditures and contributions to equity method investees.
Bankruptcies
DTE Energy Trading was the sole supplier of power for Brilliant Energy, LLC ('Brilliant'), a load serving entity and competitive retailer in ERCOT. During March 2021, Brilliant filed a voluntary petition for bankruptcy protection under Chapter 7 of the Bankruptcy Code. Subsequently, the bankruptcy court authorized a Trustee to continue managing Brilliant's business to preserve any remaining value for their creditors and begin an orderly wind-down of Brilliant's operations.

DTE Energy Company - DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) - (Continued)
In June 2021, DTE Energy Trading completed the transfer of service for all of Brilliant's customer contracts to utilities in the ERCOT market and has no further service responsibilities related to Brilliant. For pre-petition receivables that were reserved during the first quarter 2021, approximately $9 million remains reserved as of June 30, 2021. Other pre-petition receivables of approximately $3 million were recovered during the second quarter 2021 and uncollectible expense was reversed. The remaining wind-down activities are expected to be completed in the third quarter 2021. DTE Energy does not believe there is any additional risk related to this bankruptcy.
COVID-19 Pandemic
DTE Energy has been actively monitoring the impact of the COVID-19 pandemic on supply chains, markets, counterparties, and customers, and any related impacts on operating costs, customer demand, and recoverability of assets that could materially impact the Registrants' financial results.
In 2021, the COVID-19 pandemic has continued to impact DTE Electric sales volumes. As businesses have maintained certain remote operations, related sales volumes have been lower for commercial and industrial customers and higher for residential customers as compared to historical volumes before the pandemic. This impact contributed to a net reduction in DTE Electric sales, but has been offset by favorable rate mix.
In 2020, COVID-19 also resulted in incremental costs at our utilities related to personal protective equipment and other health and safety-related matters, as well as lower volumes for certain companies within the Power and Industrial Projects segment. For the three and six months ended June 30, 2021, however, there has not been any significant impact to the Registrants' Consolidated Financial Statements.
In consideration of the above factors and all other current and expected impacts to the Registrants' performance and cash flows resulting from the COVID-19 pandemic, there have been no material adjustments or reserves deemed necessary as of June 30, 2021. The Registrants cannot predict the future impacts of the COVID-19 pandemic on the Consolidated Financial Statements, as developments involving COVID-19 and its related effects on economic and operating conditions remain highly uncertain.
Other Contingencies
The Registrants are involved in certain other legal, regulatory, administrative, and environmental proceedings before various courts, arbitration panels, and governmental agencies concerning claims arising in the ordinary course of business. These proceedings include certain contract disputes, additional environmental reviews and investigations, audits, inquiries from various regulators, and pending judicial matters. The Registrants cannot predict the final disposition of such proceedings. The Registrants regularly review legal matters and record provisions for claims that they can estimate and are considered probable of loss. The resolution of these pending proceedings is not expected to have a material effect on the Registrants' Consolidated Financial Statements in the periods they are resolved.
For a discussion of contingencies related to regulatory matters and derivatives, see Notes 6 and 9 to the Consolidated Financial Statements, 'Regulatory Matters' and 'Financial and Other Derivative Instruments,' respectively.

DTE Electric participates in various plans that provide pension and other postretirement benefits for DTE Energy and its affiliates. The plans are primarily sponsored by DTE Energy's subsidiary, DTE Energy Corporate Services, LLC. DTE Electric accounts for its participation in DTE Energy's qualified and non-qualified pension plans by applying multiemployer accounting. DTE Electric accounts for its participation in other postretirement benefit plans by applying multiple-employer accounting. Within multiemployer and multiple-employer plans, participants pool plan assets for investment purposes and to reduce the cost of plan administration. The primary difference between plan types is assets contributed in multiemployer plans can be used to provide benefits for all participating employers, while assets contributed within a multiple-employer plan are restricted for use by the contributing employer. As a result of multiemployer accounting treatment, capitalized costs associated with these plans are reflected in Property, plant, and equipment in DTE Electric's Consolidated Statements of Financial Position. The same capitalized costs are reflected as Regulatory assets and liabilities in DTE Energy's Consolidated Statements of Financial Position. In addition, the service cost and non-service cost components are presented in Operation and maintenance in DTE Electric's Consolidated Statements of Operations. The same non-service cost components are presented in Other (Income) and Deductions - Non-operating retirement benefits, net in DTE Energy's Consolidated Statements of Operations. Plan participants of all plans are solely DTE Energy and affiliate participants.
DTE Energy's subsidiaries are responsible for their share of qualified and non-qualified pension benefit costs. DTE Electric's allocated portion of pension benefit costs included in capital expenditures and operating and maintenance expense was $26 million and $25 million for the three months ended June 30, 2021 and 2020, respectively, and $52 million and $51 million for the six months ended June 30, 2021 and 2020, respectively. These amounts include recognized contractual termination benefit charges, curtailment gains, and settlement charges.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
The following combined discussion is separately filed by DTE Energy and DTE Electric. However, DTE Electric does not make any representations as to information related solely to DTE Energy or the subsidiaries of DTE Energy other than itself.
EXECUTIVE OVERVIEW
DTE Energy is a diversified energy company and is the parent company of DTE Electric and DTE Gas, regulated electric and natural gas utilities engaged primarily in the business of providing electricity and natural gas sales, distribution, and storage services throughout Michigan. DTE Energy also operates three energy-related non-utility segments with operations throughout the United States.
The following table summarizes DTE Energy's financial results:
Three Months Ended June 30, Six Months Ended June 30,
2021 2020 2021 2020
(In millions, except per share amounts)
Net Income Attributable to DTE Energy Company $ 179 $ 277 $ 576 $ 617
Diluted Earnings per Common Share $ 0.92 $ 1.44 $ 2.97 $ 3.20
The decrease in Net Income for the three months ended June 30, 2021 was primarily due to lower earnings in the Corporate and Other, Energy Trading, and Power and Industrial Projects segments, partially offset by higher earnings in the Electric segment. The decrease in Net Income for the six months ended June 30, 2021 was primarily due to lower earnings in the Energy Trading, Corporate and Other, and Power and Industrial Projects segments, partially offset by higher earnings in the Electric and Gas segments.
STRATEGY
DTE Energy's strategy is to achieve long-term earnings growth, a strong balance sheet, and an attractive dividend yield.
DTE Energy's utilities are investing capital to improve customer reliability through investments in base infrastructure and new generation, and to comply with environmental requirements. DTE Energy expects that planned significant capital investments will result in earnings growth. DTE Energy is focused on executing plans to achieve operational excellence and customer satisfaction with a focus on customer affordability. DTE Energy operates in a constructive regulatory environment and has solid relationships with its regulators.
DTE Energy is committed to reduce the carbon emissions of its electric utility operations by 32% by 2023, 50% by 2030, and 80% by 2040 from 2005 carbon emissions levels. DTE Energy is also committed to a net zero carbon emissions goal by 2050 for its electric utility and gas utility operations. To achieve the reduction goals in the near term, DTE Energy will transition away from coal-powered sources and incorporate more renewable energy, energy waste reduction projects, demand response, and natural gas fueled generation. DTE Energy has already begun the transition in the way it produces power through the continued retirement of its aging coal-fired plants. Refer to the 'Capital Investments' section below for further discussion.
DTE Energy has significant investments in non-utility businesses and expects growth opportunities in its Power and Industrial Projects segment. DTE Energy employs disciplined investment criteria when assessing growth opportunities that leverage its assets, skills, and expertise, and provides diversity in earnings and geography. Specifically, DTE Energy invests in targeted energy markets with attractive competitive dynamics where meaningful scale is in alignment with its risk profile.
A key priority for DTE Energy is to maintain a strong balance sheet which facilitates access to capital markets and reasonably priced short-term and long-term financing. Near-term growth will be funded through internally generated cash flows and the issuance of debt and equity. DTE Energy has an enterprise risk management program that, among other things, is designed to monitor and manage exposure to earnings and cash flow volatility related to commodity price changes, interest rates, and counterparty credit risk.
55

CAPITAL INVESTMENTS
DTE Energy's utility businesses require significant capital investments to maintain and improve the electric generation and electric and natural gas distribution infrastructure and to comply with environmental regulations and renewable energy requirements.
DTE Electric's capital investments over the 2021-2025 period are estimated at $14 billion, comprised of $5 billion for capital replacements and other projects, $7 billion for distribution infrastructure, and $2 billion for renewable generation. DTE Electric has retired six coal-fired generation units at the Trenton Channel, River Rouge, and St. Clair facilities and has announced plans to retire its remaining eleven coal-fired generating units, including five units at Trenton Channel and St. Clair in 2022. The remaining coal-fired generating units at the Belle River and Monroe facilities are expected to be retired by 2040. Generation from the retired facilities will be replaced or offset with renewables, energy waste reduction, demand response, and natural gas fueled generation.
DTE Gas' capital investments over the 2021-2025 period are estimated at $3 billion, comprised of $1.4 billion for base infrastructure and $1.6 billion for gas main renewal, meter move out, and pipeline integrity programs.
DTE Electric and DTE Gas plan to seek regulatory approval for capital expenditures consistent with ratemaking treatment.
DTE Energy's non-utility businesses' capital investments are primarily for expansion, growth, and ongoing maintenance in the Power and Industrial Projects segment, including approximately $1 billion to $1.4 billion from 2021-2025 for industrial energy services and renewable energy projects.
ENVIRONMENTAL MATTERS
The Registrants are subject to extensive environmental regulations. Additional costs may result as the effects of various substances on the environment are studied and governmental regulations are developed and implemented. Actual costs to comply could vary substantially. The Registrants expect to continue recovering environmental costs related to utility operations through rates charged to customers, as authorized by the MPSC.
Increased costs for energy produced from traditional coal-based sources due to recent, pending, and future regulatory initiatives could also increase the economic viability of energy produced from renewable, natural gas fueled generation, and/or nuclear sources, energy waste reduction initiatives, and the potential development of market-based trading of carbon instruments which could provide new business opportunities for DTE Energy's utility and non-utility segments. At the present time, it is not possible to quantify the financial impacts of these climate related regulatory initiatives on the Registrants or their customers.
For further discussion of environmental matters, see Note 13 to the Consolidated Financial Statements, 'Commitments and Contingencies.'
56

OUTLOOK
The next few years will be a period of rapid change for DTE Energy and for the energy industry. DTE Energy's strong utility base, combined with its integrated non-utility operations, position it well for long-term growth.
Looking forward, DTE Energy will focus on several areas that are expected to improve future performance:
•electric and gas customer satisfaction;
•electric distribution system reliability;
•new electric generation;
•gas distribution system renewal;
•rate competitiveness and affordability;
•regulatory stability and investment recovery for the electric and gas utilities;
•employee safety and engagement;
•cost structure optimization across all business segments;
•cash, capital, and liquidity to maintain or improve financial strength; and
•investments that integrate assets and leverage skills and expertise.
On July 1, 2021, DTE Energy completed the separation of DT Midstream, as discussed in Note 4 to the Consolidated Financial Statements, 'Dispositions and Impairments.' The separation will result in a reduction to DTE Energy's earnings and cash flows in the near term. However, DTE Energy remains well-positioned for long-term growth and focused on the key objectives noted above. DTE Energy will continue to pursue opportunities to grow its businesses in a disciplined manner if it can secure opportunities that meet its strategic, financial, and risk criteria.
COVID-19 Pandemic
DTE Energy has been monitoring the COVID-19 pandemic and any related impacts to operating costs, customer demand, and the recoverability of assets in our business segments that could materially impact the Registrants' financial results.
As noted in Note 13 to the Consolidated Financial Statements, 'Commitments and Contingencies,' the pandemic has contributed to a shift in electric sales volumes from commercial and industrial customers to residential customers. DTE Energy expects this shift to continue in the near term as businesses maintain more remote operations. Other impacts from COVID-19 have related primarily to health and safety-related costs at the utilities and volumes at certain non-utility businesses, but these impacts have not been significant in 2021.
DTE Energy will continue to monitor these impacts as well as any regulatory and legislative activities related to COVID-19. The Registrants cannot predict the ultimate impact of these factors to our Consolidated Financial Statements as future developments involving COVID-19 and related impacts on economic and operating conditions are highly uncertain.

RESULTS OF OPERATIONS
Management's Discussion and Analysis of Financial Condition and Results of Operations includes financial information prepared in accordance with GAAP, as well as the non-GAAP financial measures, Utility Margin and Non-utility Margin, discussed below, which DTE Energy uses as measures of its operational performance. Generally, a non-GAAP financial measure is a numerical measure of financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.
DTE Energy uses Utility Margin and Non-utility Margin, non-GAAP financial measures, to assess its performance by reportable segment.
57

Utility Margin includes electric utility and gas utility Operating Revenues net of Fuel, purchased power, and gas expenses. The utilities' fuel, purchased power, and natural gas supply are passed through to customers, and therefore, result in changes to the utilities' revenues that are comparable to changes in such expenses. As such, DTE Energy believes Utility Margin provides a meaningful basis for evaluating the utilities' operations across periods, as it excludes the revenue effect of fluctuations in these expenses. For the Electric segment, non-utility Operating Revenues are reported separately so that Utility Margin can be used to assess utility performance.
The Non-utility Margin relates to the Power and Industrial Projects and Energy Trading segments. For the Power and Industrial Projects segment, Non-utility Margin primarily includes Operating Revenues net of Fuel, purchased power, and gas expenses. Operating Revenues include sales of refined coal to third parties and the affiliated Electric utility, metallurgical coke and related by-products, petroleum coke, renewable natural gas and related credits, and electricity, as well as rental income and revenues from utility-type consulting, management, and operational services. For the Energy Trading segment, Non-utility Margin includes revenue and realized and unrealized gains and losses from physical and financial power and gas marketing, optimization, and trading activities, net of Purchased power and gas related to these activities. DTE Energy evaluates its operating performance of these non-utility businesses using the measure of Operating Revenues net of Fuel, purchased power, and gas expenses.
Utility Margin and Non-utility Margin are not measures calculated in accordance with GAAP and should be viewed as a supplement to and not a substitute for the results of operations presented in accordance with GAAP. Utility Margin and Non-utility Margin do not intend to represent operating income, the most comparable GAAP measure, as an indicator of operating performance and are not necessarily comparable to similarly titled measures reported by other companies.
The following sections provide a detailed discussion of the operating performance and future outlook of DTE Energy's segments. Segment information, described below, includes intercompany revenues and expenses, and other income and deductions that are eliminated in the Consolidated Financial Statements.

Operation and maintenanceexpense increased $5 million and $3 million in the three and six months ended June 30, 2021, respectively. The increase in the second quarter was primarily due to higher benefits expense of $12 million, higher EWR expense of $12 million, higher generation expense of $8 million, and higher distribution operations expense of $8 million, partially offset by 2020 COVID-19 related expenses of $29 million associated with the health and safety of employees and lower uncollectible expense of $4 million. The increase in the six-month period was primarily due to higher benefits expense of $25 million, higher EWR expense of $21 million, and higher corporate support costs of $5 million. These increases were partially offset by 2020 COVID-19 related expenses of $29 million, lower uncollectible expense of $10 million, and lower generation expense of $9 million.
Depreciation and amortizationexpense increased $19 million and $22 million in the three and six months ended June 30, 2021, respectively. The increase in the second quarter was primarily due to an $18 million increase resulting from a higher depreciable base and a $1 million increase associated with the TRM. The increase in the six-month period was primarily due to a $26 million increase resulting from a higher depreciable base, partially offset by a $1 million decrease associated with the TRM.
Taxes other than incomeincreased $23 million and $22 million in the three and six months ended June 30, 2021, respectively. The increase in the second quarter was primarily due to higher property taxes of $20 million which resulted primarily from a favorable property tax settlement in 2020, and higher payroll taxes of $2 million driven primarily by employee retention credits recognized in 2020 pursuant to the CARES Act. The increase in the six-month period was primarily due to higher property taxes of $20 million and higher payroll taxes of $1 million, primarily resulting from the respective property tax settlement and employee retention credits recognized in 2020.
Asset (gains) losses and impairments, netdecreased $41 million in the three and six months ended June 30, 2021. The decrease in both periods was primarily due to a 2020 write-off of capital expenditures related to incentive compensation, which were disallowed in the May 8, 2020 rate order from the MPSC.
Other (Income) and Deductions increased $20 million in the three months ended June 30, 2021 and decreased $19 million in the six months ended June 30, 2021. The increase in the second quarter was primarily due to a change in rabbi trust investment earnings (gain of $2 million in 2021 compared to a gain of $22 million in 2020). The decrease in the six-month period was primarily due to a change in rabbi trust investment earnings (gain of $4 million in 2021 compared to a loss of $9 million in 2020) and lower non-operating retirement benefits expense of $4 million.
Income Tax Expenseincreased $2 million and $9 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to higher earnings, partially offset by higher amortization of the TCJA regulatory liability and higher production tax credits.

Outlook -DTE Electric will continue to move forward in its efforts to achieve operational excellence, sustain strong cash flows, and earn its authorized return on equity. DTE Electric expects that planned significant capital investments will result in earnings growth. DTE Electric will maintain a strong focus on customers by increasing reliability and satisfaction while keeping customer rate increases affordable. Looking forward, additional factors may impact earnings such as weather, the outcome of regulatory proceedings, benefit plan design changes, investment returns and changes in discount rate assumptions in benefit plans and health care costs, uncertainty of legislative or regulatory actions regarding climate change, and effects of energy waste reduction programs.
On March 26, 2021, DTE Electric filed an application requesting a financing order approving the securitization of $184 million of qualified costs related to the net book value of the River Rouge generation plant and tree trimming surge program costs. The filing requested collection of these qualifying costs from DTE Electric's customers. A final MPSC order was issued on June 23, 2021 authorizing DTE Electric to proceed with the issuance of securitization bonds for qualified costs of up to $236 million, increased for the inclusion of deferred taxes. The order authorized customer charges for the timely recovery of the amount securitized and other ongoing qualified costs. Securitization is expected in the fourth quarter 2021.

Income Tax Expensedecreased $6 million in the six months ended June 30, 2021. The decrease was primarily due to an higher amortization of the TCJA regulatory liability, partially offset by higher earnings.
Outlook -DTE Gas will continue to move forward in its efforts to achieve operational excellence, sustain strong cash flows, and earn its authorized return on equity. DTE Gas expects that planned significant infrastructure capital investments will result in earnings growth. Looking forward, additional factors may impact earnings such as weather, the outcome of regulatory proceedings, benefit plan design changes, and investment returns and changes in discount rate assumptions in benefit plans and health care costs. DTE Gas expects to continue its efforts to improve productivity and decrease costs while improving customer satisfaction with consideration of customer rate affordability.
DTE Gas filed a rate case with the MPSC on February 12, 2021 requesting an increase in base rates of $195 million based on a projected twelve-month period ending December 31, 2022. The requested increase in base rates is primarily due to an increase in net plant resulting from infrastructure investments and operating and maintenance expenses. The rate filing also requested an increase in return on equity from 9.9% to 10.25% and includes projected changes in sales and working capital. A final MPSC order in this case is expected by December 2021.

Operating Revenues - Non-utility operations increased $36 million and $63 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to higher pipeline revenues from LEAP, which was placed in-service during the third quarter 2020, as well as higher revenues from Blue Union and AGS.
Cost of gas and other - Non-utility increased $6 million and $7 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to higher physical purchases of gas from AGS customers.
Operation and maintenance expense increased $20 million and $37 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to transaction costs related to the separation of DT Midstream, higher operation and maintenance costs at Blue Union, and cost savings initiatives in 2020.
Depreciation and amortization expense increased $5 million and $10 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to LEAP, which was placed in-service during the third quarter 2020.
Taxes other than income increased $2 million and $4 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to higher property taxes from placing LEAP in-service.
Asset (gains) losses and impairments, net increased $18 million and $17 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to a $19 million impairment of notes receivable for an investment in certain assets in the Utica shale region.
Other (Income) and Deductionsincreased $7 million and $14 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to higher earnings from pipeline investments and lower interest expense.
Outlook -On July 1, 2021, DTE Energy completed the separation of DT Midstream, which is primarily comprised of the Gas Storage and Pipelines segment. Effective with the separation, DTE Energy no longer retains ownership in DT Midstream. Beginning in the third quarter 2021, DTE Energy will have no further activity related to DT Midstream and historical results will be presented as discontinued operations.
Refer to Note 4 to the Consolidated Financial Statements, 'Dispositions and Impairments,' for additional information regarding the separation of DT Midstream.

64

Asset (gains) losses and impairments, netincreased $27 million and $37 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to an asset impairment of $27 million recorded in the Steel business for the anticipated closure of a pulverized coal facility. The increase in the six-month period was also due to $10 million of activity in 2020, including the write-off of environmental liabilities upon completing site remediation in the Steel business and the sale of assets in the On-site business.
Refer to Note 4 to the Consolidated Financial Statements, 'Dispositions and Impairments,' for additional information regarding the $27 million asset impairment and consideration of any additional impacts to future periods.
Other (Income) and Deductionsdecreased $8 million and $6 million in the three and six months ended June 30, 2021, respectively. The decrease in both periods was primarily due to $11 million of profit recognized from the sale of membership interests in the REF business in 2020, partially offset by higher production in the REF business in 2021.
Income Taxes - Production Tax Creditsincreased $3 million and $8 million in the three and six months ended June 30, 2021, respectively. The increase in both periods was primarily due to higher production partially offset by the sale of membership interests in the REF business.
Net Loss Attributable to Noncontrolling Interestsincreased $3 million in the six months ended June 30, 2021. The increase was primarily due to higher production in the REF business.
Outlook -Power and Industrial Projects will continue to leverage its extensive energy-related operating experience and project management capability to develop additional energy and renewable natural gas projects to serve energy intensive industrial customers in addition to optimizing the REF facilities until the phase-out at the end of 2021. Beginning in 2022, Power and Industrial Projects expects decreases in Other Income and Production Tax Credits that will cause a corresponding reduction to Net Income as REF facilities will cease operations. Over the long-term, Power and Industrial Projects expects growth in industrial energy services projects and renewable energy projects will offset the decreases to Net Income caused by the REF phase-out.

Outlook -In the near-term, Energy Trading expects market conditions to remain challenging. The profitability of this segment may be impacted by the volatility in commodity prices and the uncertainty of impacts associated with regulatory changes, and changes in operating rules of Regional Transmission Organizations. Significant portions of the Energy Trading portfolio are economically hedged. Most financial instruments, physical power and natural gas contracts, and certain environmental contracts are deemed derivatives; whereas, natural gas and environmental inventory, contracts for pipeline transportation, storage assets, and some environmental contracts are not derivatives. As a result, Energy Trading will experience earnings volatility as derivatives are marked-to-market without revaluing the underlying non-derivative contracts and assets. Energy Trading's strategy is to economically manage the price risk of these underlying non-derivative contracts and assets with futures, forwards, swaps, and options. This results in gains and losses that are recognized in different interim and annual accounting periods.
See also the 'Fair Value' section herein and Notes 8 and 9 to the Consolidated Financial Statements, 'Fair Value' and 'Financial and Other Derivative Instruments,' respectively.

CORPORATE AND OTHER
Corporate and Other includes various holding company activities, holds certain non-utility debt, and holds certain investments, including funds supporting regional development and economic growth. The net loss of $78 million and $110 million for the three and six months ended June 30, 2021, respectively, represents an increase of $77 million and $98 million from the net loss of $1 million and $12 million in the comparable 2020 periods. The increase in both periods was primarily due to the carryback of 2018 net operating losses to 2013 pursuant to the CARES Act, which resulted in a $34 million reduction to Income Tax Expense in 2020. The increase in both periods was also due to effective income tax rate adjustments, higher net interest expense, higher state income taxes, and transaction costs related to the separation of DT Midstream.

CAPITAL RESOURCES AND LIQUIDITY
Cash Requirements
DTE Energy uses cash to maintain and invest in the electric and natural gas utilities, to grow the non-utility businesses, to retire and pay interest on long-term debt, and to pay dividends. DTE Energy believes it will have sufficient internal and external capital resources to fund anticipated capital and operating requirements. DTE Energy expects that cash from operations in 2021 will be approximately $2.7 billion. DTE Energy anticipates base level utility capital investments, including environmental, renewable, and energy waste reduction expenditures; expenditures for non-utility businesses; and contributions to equity method investees in 2021 of approximately $3.9 billion. DTE Energy plans to seek regulatory approval to include utility capital expenditures in regulatory rate base consistent with prior treatment. Capital spending for growth of existing or new non-utility businesses will depend on the existence of opportunities that meet strict risk-return and value creation criteria.
Refer to the 'Capital Investments' section above for additional information on DTE Energy's capital strategy and estimated spend over the next five years. Any capital commitments are also included in the disclosure of Purchase Commitments within Note 13 to the Consolidated Financial Statements, 'Commitments and Contingencies.'

Net Increase in Cash, Cash Equivalents, and Restricted Cash 2,934 528
Cash, Cash Equivalents, and Restricted Cash at End of Period $ 3,450 $ 621
Cash from Operating Activities
A majority of DTE Energy's operating cash flows are provided by the electric and natural gas utilities, which are significantly influenced by factors such as weather, electric retail access, regulatory deferrals, regulatory outcomes, economic conditions, changes in working capital, and operating costs.
Net cash from operations increased by $235 million in 2021. The increase was primarily due to an increase from working capital items, partially offset by a decrease in Deferred income taxes.
The change in working capital items in 2021 was primarily due to an increase in cash related to Regulatory assets and liabilities, Derivative assets and liabilities, and Accounts payable, partially offset by a decrease in cash related to Accounts receivable, net, Inventories, and Other current and noncurrent assets and liabilities.
Cash used for Investing Activities
Cash inflows associated with investing activities are primarily generated from the sale of assets, while cash outflows are the result of plant and equipment expenditures and acquisitions. In any given year, DTE Energy looks to realize cash from under-performing or non-strategic assets or matured, fully valued assets.
67

Capital spending within the utility businesses is primarily to maintain and improve electric generation and the electric and natural gas distribution infrastructure, and to comply with environmental regulations and renewable energy requirements.
Capital spending within the non-utility businesses is primarily for ongoing maintenance, expansion, and growth. DTE Energy looks to make growth investments that meet strict criteria in terms of strategy, management skills, risks, and returns. All new investments are analyzed for their rates of return and cash payback on a risk adjusted basis. DTE Energy has been disciplined in how it deploys capital and will not make investments unless they meet the criteria. For new business lines, DTE Energy initially invests based on research and analysis. DTE Energy starts with a limited investment, evaluates the results, and either expands or exits the business based on those results. In any given year, the amount of growth capital will be determined by the underlying cash flows of DTE Energy, with a clear understanding of any potential impact on its credit ratings.
Net cash used for investing activities decreased by $257 million in 2021 primarily due to a decrease in non-utility plant and equipment expenditures and a decrease in Acquisitions related to business combinations, net of cash acquired, partially offset by an increase in utility plant and equipment expenditures.
Cash from Financing Activities
DTE Energy relies on both short-term borrowing and long-term financing as a source of funding for capital requirements not satisfied by its operations.
DTE Energy's strategy is to have a targeted debt portfolio blend of fixed and variable interest rates and maturity. DTE Energy targets balance sheet financial metrics to ensure it is consistent with the objective of a strong investment grade debt rating.
Net cash from financing activities increased by $1.9 billion in 2021 primarily due to an increase in Issuances of long-term debt, net of issuance costs, partially offset by an increase in Redemption of long-term debt, a decrease in Short-term borrowings, net, and a Repurchase of common stock.
Outlook
DTE Energy expects cash flows from operations to increase over the long-term, primarily as a result of growth from the utility and non-utility businesses. Growth in the utilities is expected to be driven primarily by capital spending which will increase the base from which rates are determined. Non-utility growth is expected from additional investments in the Power and Industrial Projects segment. Power and Industrial Projects cash flows are expected to temporarily decrease beginning in 2022 as REF facilities will have ceased operations. Growth from new industrial energy services projects and renewable energy investments are expected to offset these decreases over the long-term.
DTE Energy's separation of DT Midstream will also reduce operating cash flows in the near term. However, DTE Energy still expects higher cash flows from operations over the long-term due to the growth of its utilities and other non-utility operations.
DTE Energy may be impacted by the timing of collection or refund of various recovery and tracking mechanisms, as a result of timing of MPSC orders. Energy prices are likely to be a source of volatility with regard to working capital requirements for the foreseeable future. DTE Energy continues its efforts to identify opportunities to improve cash flows through working capital initiatives and maintaining flexibility in the timing and extent of long-term capital projects.
In July 2021, DTE Energy optionally redeemed $2.2 billion of long-term debt and incurred prepayment costs of $235 million. DTE Energy also provided notice of its intent to call for redemption an additional $374 million of long-term debt and will incur additional prepayment costs when the debt is redeemed in August 2021. These redemptions are being made using proceeds from DT Midstream's repayment of intercompany borrowings and one-time special dividend and will reduce interest expense in future periods. Refer to Notes 4 and 10 to the Consolidated Financial Statements, 'Dispositions and Impairments' and 'Long-term Debt,' respectively, for additional information.
As of June 30, 2021, DTE Energy had $1.0 billion in long-term debt, including finance leases, maturing within twelve months. Of this amount, $600 million was repaid in July 2021 as part of the early redemptions noted above. Remaining long-term debt of $447 million maturing in the next twelve months is expected to be paid through internally generated funds or the issuance of new long-term debt.
68

DTE Energy has approximately $5.9 billion of available liquidity at June 30, 2021, consisting primarily of cash and cash equivalents and amounts available under unsecured revolving credit agreements. Available liquidity at June 30, 2021 was higher due to one-time actions taken to support the separation of DT Midstream, including $3.0 billion of net proceeds from DT Midstream's issuance of long-term debt and ensuing payments to DTE Energy. These proceeds were held in a temporary investment account and included in Cash and cash equivalents in the Consolidated Statements of Financial Position as of June 30, 2021. DTE Energy expects the amount of available liquidity to be more aligned with historical levels in the third quarter 2021 after the cash proceeds are used for the debt redemptions noted above.
DTE Energy does not currently expect any equity issuances for 2021. However, management will continue to monitor economic and financial market conditions and if circumstances warrant, DTE Energy may issue equity up to $200 million in 2021. If issued, DTE Energy anticipates up to $100 million of these equity issuances would be made through contributions to the qualified pension plans at DTE Electric. DTE Energy does not anticipate making any contributions to its other postretirement benefit plans in 2021. Additional equity issuances, if any, would be made through other employee benefit plans.
To finance the acquisition of midstream natural gas assets in December 2019, DTE Energy issued equity units that will result in the issuance of common stock in November 2022. This transaction is not expected to impact DTE Energy's cash flows. Cash flow impacts in 2021-2022 will relate primarily to the payment of the remaining stock purchase liability associated with the equity units, which will remain with DTE Energy after the separation of DT Midstream. Over the long-term, DTE Energy does not have any other equity commitments and will continue to evaluate equity needs on an annual basis in consideration of economic and financial market conditions.
DTE Energy has paid quarterly cash dividends for more than 100 consecutive years and expects to continue paying regular cash dividends in the future, including approximately $0.8 billion in 2021. Any payment of future dividends is subject to approval by the Board of Directors and may depend on DTE Energy's future earnings, capital requirements, and financial condition. Over the long-term, DTE Energy expects continued dividend growth and is targeting a payout ratio consistent with pure-play utility companies.
Various subsidiaries and equity investees of DTE Energy have entered into contracts which contain ratings triggers and are guaranteed by DTE Energy. These contracts contain provisions which allow the counterparties to require that DTE Energy post cash or letters of credit as collateral in the event that DTE Energy's credit rating is downgraded below investment grade. Certain of these provisions (known as 'hard triggers') state specific circumstances under which DTE Energy can be required to post collateral upon the occurrence of a credit downgrade, while other provisions (known as 'soft triggers') are not as specific. For contracts with soft triggers, it is difficult to estimate the amount of collateral which may be requested by counterparties and/or which DTE Energy may ultimately be required to post. The amount of such collateral which could be requested fluctuates based on commodity prices (primarily natural gas, power, environmental, and coal) and the provisions and maturities of the underlying transactions. As of June 30, 2021, DTE Energy's contractual obligation to post collateral in the form of cash or letters of credit in the event of a downgrade to below investment grade, under both hard trigger and soft trigger provisions, was $467 million.
DTE Energy believes it will have sufficient operating flexibility, cash resources, and funding sources to maintain adequate amounts of liquidity and to meet future operating cash and capital expenditure needs. However, virtually all of DTE Energy's businesses are capital intensive, or require access to capital, and the inability to access adequate capital could adversely impact earnings and cash flows.
See Notes 6, 10, 11, 13, and 14 to the Consolidated Financial Statements, 'Regulatory Matters,' 'Long-Term Debt,' 'Short-Term Credit Arrangements and Borrowings,' 'Commitments and Contingencies,' and 'Retirement Benefits and Trusteed Assets,' respectively.

FAIR VALUE
Derivatives are generally recorded at fair value and shown as Derivative assets or liabilities. Contracts DTE Energy typically classifies as derivative instruments include power, natural gas, some environmental contracts, and certain forwards, futures, options and swaps, and foreign currency exchange contracts. Items DTE Energy does not generally account for as derivatives include natural gas and environmental inventory, pipeline transportation contracts, storage assets, and some environmental contracts. See Notes 8 and 9 to the Consolidated Financial Statements, 'Fair Value' and 'Financial and Other Derivative Instruments,' respectively.
The tables below do not include the expected earnings impact of non-derivative natural gas storage, transportation, certain power contracts, and some environmental contracts which are subject to accrual accounting. Consequently, gains and losses from these positions may not match with the related physical and financial hedging instruments in some reporting periods, resulting in volatility in the Registrants' reported period-by-period earnings; however, the financial impact of the timing differences will reverse at the time of physical delivery and/or settlement.
The Registrants manage their MTM risk on a portfolio basis based upon the delivery period of their contracts and the individual components of the risks within each contract. Accordingly, the Registrants record and manage the energy purchase and sale obligations under their contracts in separate components based on the commodity (e.g. electricity or natural gas), the product (e.g. electricity for delivery during peak or off-peak hours), the delivery location (e.g. by region), the risk profile (e.g. forward or option), and the delivery period (e.g. by month and year).
The Registrants have established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). For further discussion of the fair value hierarchy, see Note 8 to the Consolidated Financial Statements, 'Fair Value.'
The following table provides details on changes in DTE Energy's MTM net asset (or liability) position:

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Market Price Risk
The Electric and Gas businesses have commodity price risk, primarily related to the purchases of coal, natural gas, uranium, and electricity. However, the Registrants do not bear significant exposure to earnings risk, as such changes are included in the PSCR and GCR regulatory rate-recovery mechanisms. In addition, changes in the price of natural gas can impact the valuation of lost and stolen gas, storage sales, and transportation services revenue at the Gas segment. The Gas segment manages its market price risk related to storage sales revenue primarily through the sale of long-term storage contracts. The Registrants are exposed to short-term cash flow or liquidity risk as a result of the time differential between actual cash settlements and regulatory rate recovery.
DTE Energy's Power and Industrial Projects business segment is subject to electricity, natural gas, and coal product price risk. DTE Energy manages its exposure to commodity price risk through the use of long-term contracts.
DTE Energy's Energy Trading business segment has exposure to electricity, natural gas, environmental, crude oil, heating oil, and foreign currency exchange price fluctuations. These risks are managed by the energy marketing and trading operations through the use of forward energy, capacity, storage, options, and futures contracts, within predetermined risk parameters.
Credit Risk
Bankruptcies
DTE Energy Trading was the sole supplier of power for Brilliant Energy, LLC ('Brilliant'), a load serving entity and competitive retailer in ERCOT. During March 2021, Brilliant filed a voluntary petition for bankruptcy protection under Chapter 7 of the Bankruptcy Code.
Refer to Note 13 to the Consolidated Financial Statements, 'Commitments and Contingencies,' for details regarding the bankruptcy, including the status of customer receivables. Remaining wind-down activities related to Brilliant are expected to be completed in the third quarter 2021 and DTE Energy does not believe there is any additional risk related to this bankruptcy.
Allowance for Doubtful Accounts
The Registrants regularly review contingent matters, existing and future economic conditions, customer trends and other factors relating to customers and their contracts and record provisions for amounts considered at risk of probable loss in the allowance for doubtful accounts. The Registrants believe their accrued amounts are adequate for probable loss.

71

Trading Activities
DTE Energy is exposed to credit risk through trading activities. Credit risk is the potential loss that may result if the trading counterparties fail to meet their contractual obligations. DTE Energy utilizes both external and internal credit assessments when determining the credit quality of trading counterparties.
The following table displays the credit quality of DTE Energy's trading counterparties as of June 30, 2021:

(a)This category includes counterparties with minimum credit ratings of Baa3 assigned by Moody's Investors Service (Moody's) or BBB-assigned by Standard & Poor's Rating Group, a division of McGraw-Hill Companies, Inc. (Standard & Poor's). The five largest counterparty exposures, combined, for this category represented 14% of the total gross credit exposure.
(b)This category includes counterparties with credit ratings that are below investment grade. The five largest counterparty exposures, combined, for this category represented less than 1% of the total gross credit exposure.
(c)This category includes counterparties that have not been rated by Moody's or Standard & Poor's but are considered investment grade based on DTE Energy's evaluation of the counterparty's creditworthiness. The five largest counterparty exposures, combined, for this category represented 14% of the total gross credit exposure.
(d)This category includes counterparties that have not been rated by Moody's or Standard & Poor's and are considered non-investment grade based on DTE Energy's evaluation of the counterparty's creditworthiness. The five largest counterparty exposures, combined, for this category represented 4% of the total gross credit exposure.
Other
The Registrants engage in business with customers that are non-investment grade. The Registrants closely monitor the credit ratings of these customers and, when deemed necessary and permitted under the tariffs, request collateral or guarantees from such customers to secure their obligations.
Interest Rate Risk
DTE Energy is subject to interest rate risk in connection with the issuance of debt. In order to manage interest costs, DTE Energy may use treasury locks and interest rate swap agreements. DTE Energy's exposure to interest rate risk arises primarily from changes in U.S. Treasury rates, commercial paper rates, and LIBOR. As of June 30, 2021, DTE Energy had floating rate debt of $1.1 billion and a floating rate debt-to-total debt ratio of 4.65%, primarily relating to the $1.0 billion variable rate term loan issued in June 2021 that will not be retained by DTE Energy upon the separation of DT Midstream on July 1, 2021.
Foreign Currency Exchange Risk
DTE Energy has foreign currency exchange risk arising from market price fluctuations associated with fixed priced contracts. These contracts are denominated in Canadian dollars and are primarily for the purchase and sale of natural gas and power, as well as for long-term transportation capacity. To limit DTE Energy's exposure to foreign currency exchange fluctuations, DTE Energy has entered into a series of foreign currency exchange forward contracts through June 2030.
72

Summary of Sensitivity Analyses
Sensitivity analyses were performed on the fair values of commodity contracts for DTE Energy and long-term debt obligations for the Registrants. The commodity contracts listed below principally relate to energy marketing and trading activities. The sensitivity analyses involved increasing and decreasing forward prices and rates at June 30, 2021 and 2020 by a hypothetical 10% and calculating the resulting change in the fair values. The hypothetical losses related to long-term debt would be realized only if DTE Energy transferred all of its fixed-rate long-term debt to other creditors.
