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, the MDEQ,EGLE, and for DTE Energy, the CFTC.
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 20182019 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.

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, 2019.

2020.
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.
Certain prior year balances for the Registrants were reclassified to match the current year's Consolidated Financial Statements presentation.
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 cost method is used. 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.
DTE Energy currently owns an 85% interest in SGG, which owns and operates midstream natural gas assets. SGG has contracts through which certain construction risk is 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 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 23-mile regulated pipeline system located in northern Ohio, which was acquired in September 2019. 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, as well as, 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.

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. As of June 30, 2019,March 31, 2020, 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, 2019,March 31, 2020, 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 significant0 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 significant0 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 1213 to the Consolidated Financial Statements, "Commitments and Contingencies," related to the 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. See Note 1213 to the Consolidated Financial Statements, "Commitments and Contingencies," for further discussion of the NEXUS guarantee arrangements.
The following table summarizes the major Consolidated Statements of Financial Position items for consolidated VIEs as of June 30, 2019March 31, 2020 and December 31, 2018.2019. 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.
Amounts for DTE Energy's consolidated VIEs are as follows:

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, DTE Energy's interest in other comprehensive income of equity investees which comprise the net unrealized gains and losses on investments, 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 further discussion regarding changes in Accumulated other comprehensive income (loss), see Note 3 to the Consolidated Financial Statements, "New Accounting Pronouncements." For the three and six months ended June 30, 2019 and 2018,March 31, 2020, reclassifications out of Accumulated other comprehensive income (loss) not relating to the adoption of new accounting pronouncements for DTE Energy were not material.

Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

For the three months ended March 31, 2019, DTE Energy reclassified $25 million of stranded tax effects resulting from the TCJA from Accumulated other comprehensive income (loss) to Retained Earnings. The reclassification was recorded upon adoption of ASU No. 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income on January 1, 2019. Reclassifications out of Accumulated other comprehensive income (loss) not relating to the adoption of this standard were not material.
Income Taxes
The 2019 estimated annualinterim effective tax rates for DTE Energy and DTE Electricof the Registrants are 12% and 16%, respectively. as follows:
 Effective Tax Rate
 Three Months Ended March 31,
 2020 2019
DTE Energy13% 12%
DTE Electric12% 16%

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 interim effective tax rate of the Registrants are as follows:
 Effective Tax Rate
 Three Months Ended June 30, Six Months Ended June 30,
 2019 2018 2019 2018
DTE Energy11% 7% 11% 13%
DTE Electric16% 21% 16% 23%

The 4%1% increase in DTE Energy's effective tax rate for the three months ended June 30, 2019March 31, 2020 was primarily due to lowera decrease in annual production tax credits of 7%2%, a decrease in 2019,stock-based compensation tax benefit of 1%, partially offset by thehigher amortization of the TCJA regulatory liability of 3%2% in 2019. The 2% decrease in DTE Energy's effective tax rate for the six months ended June 30, 2019 was primarily due to the amortization of the TCJA regulatory liability of 3% in 2019 and the remeasurement of deferred taxes in 2018 of $21 million that impacted the effective tax rate by 3%. The decrease in the effective tax rate was partially offset by lower production tax credits of 4% in 2019.2020.
The 5% and 7%4% decrease in DTE Electric's effective tax rate for the three and six months ended June 30, 2019, respectively,March 31, 2020 was primarily due to thehigher amortization of the TCJA regulatory liability of 4%3% and higheran increase in annual production tax credits of 1% in 2019. The remeasurement of deferred taxes in 2018 of2020.
DTE Energy had $8 million impacted the effective tax rate by 2% for the six months ended June 30, 2019.
DTE Energy's total amount of unrecognized tax benefits as of June 30, 2019 was $8 million, whichat March 31, 2020, that if recognized, would favorably impact its effective tax rate. DTE Electric's total amountElectric had $10 million of unrecognized tax benefits as of June 30, 2019 was $10 million, whichat March 31, 2020, that if recognized, would favorably impact its effective tax rate.

In March 2020, the "Coronavirus Aid, Relief, and Economic Security Act" (CARES Act) was signed into law and included several significant changes to the Internal Revenue Code. The CARES Act includes certain tax relief provisions applicable to the Registrants including a) the immediate refund of the corporate AMT credit, b) the ability to carryback net operating losses five years for tax years 2018 through 2020, c) delayed payment of employer payroll taxes, and d) the employee retention credit.
As of March 31, 2020, DTE Energy had a $153 million AMT credit refund recorded in anticipation of a refund from the U.S. Treasury. DTE Energy was most recently a taxpayer in 2013 and is currently evaluating the ability to recover cash taxes paid in 2013 under the 5-year net operating loss carryback provision. The Registrants also implemented the deferral of employee payroll taxes in April 2020 and are evaluating the impact of the employee retention credit.
Unrecognized Compensation Costs
As of June 30, 2019,March 31, 2020, DTE Energy had $104$91 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 1.541.88 years.

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 requirements ofcontractual obligations to fund certain debtconstruction projects and DTE Energy partnership operating agreements.guarantee performance. Restricted cash designated for interest and principal payments within one year is classified as a Current Asset.
Financing Receivables
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 March 2020.

The allowance for doubtful accounts on accounts receivable for the utility entities is generally calculated using the 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.

Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

Notes receivable, or financing receivables, 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, or financing receivables, 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 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.

Bad debt expense for the three months ended March 31, 2019 was $29 million and $16 million for DTE Energy and DTE Electric, respectively.
The Registrants are monitoring the impacts from the COVID-19 pandemic on our customers and various counterparties. During the three months ended March 31, 2020, the allowance for doubtful accounts was increased to account for additional risk related to the pandemic. However, these adjustments were not material.
In April 2020, the MPSC issued an order in response to the COVID-19 pandemic and authorized the deferral of certain uncollectible expense that is in excess of the amount used to set current rates. DTE Energy is still evaluating this order for any potential impact to the allowance for doubtful accounts. Refer to Note 6 to the Consolidated Financial Statements, "Regulatory Matters," for further information regarding the order.
There are no material amounts of past due financing receivables for the Registrants as of March 31, 2020.

NOTE 3 — NEW ACCOUNTING PRONOUNCEMENTS
Recently Adopted Pronouncements
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), as amended. This guidance requires a lessee to account for leases as finance or operating leases and disclose key information about leasing arrangements. Both types of leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability on its balance sheet, with differing methodology for income statement recognition, depending on the lease classification. The Registrants adopted the standard on January 1, 2019 using the prospective approach. The standard provides a number of transition practical expedients of which the Registrants elected the package of three expedients that must be taken together, allowing entities to not reassess whether an agreement is a lease, to carryforward the existing lease classification, and to not reassess initial direct costs associated with existing leases; but did not elect to apply hindsight in determining lease term and impairment of the right-of-use assets. The Registrants also elected to not evaluate land easements under the new guidance at adoption if they were not previously accounted for as leases.

NOTE 4 — ACQUISITIONS
Power and Industrial Projects Segment Acquisition
On February 18, 2020, DTE Energy closed on the purchase of an 8 MW combined heat and power generation facility from South Jersey Industries (“SJI”) that provides electricity and hot and chilled water to a hotel and casino in Atlantic City, New Jersey. Direct transaction costs primarily related to advisory fees were immaterial and are included in Operation and maintenance in DTE Energy's Consolidated Statements of Operations. The fair value of consideration provided for the acquisition was approximately $97 million paid in cash.
The acquisition was accounted for using the acquisition method of accounting for business combinations. Accordingly, the cost was allocated to the underlying net assets based on their respective fair values as shown below:
 (In millions)
Contract intangibles$18
Property, plant, and equipment, net76
Working capital3
Total$97

The intangible assets recorded pertain to existing customer contracts and were estimated by applying the income approach, based on discounted projected cash flows attributable to the existing agreements. The contract intangible assets are amortized on a straight-line basis over a period of 13 years, which is based on the number of years the assets are expected to economically contribute to the business. The pro forma financial information has not been presented for DTE Energy because the effects of the acquisition were not material to the Consolidated Statements of Operations.
Electric Segment Acquisitions
Effective September 12, 2019, DTE Sustainable Generation closed on the purchase of an 89 MW renewable energy project located in Michigan from Heritage Sustainable Energy in support of DTE Energy's renewable energy goals. Direct transaction costs primarily related to advisory fees were immaterial and were included in Operation and maintenance in DTE Energy's Consolidated Statements of Operations for the period incurred. The fair value of consideration provided for the acquisition was approximately $175 million, paid in cash.
The acquisition was accounted for using the acquisition method of accounting for business combinations. Accordingly, the cost was allocated to the underlying net assets based on their respective fair values as shown below:
 (In millions)

The intangible assets recorded pertain to existing customer contracts and were estimated by applying the income approach, based on discounted projected cash flows attributable to the existing agreements. The contract intangible assets are amortized on a straight-line basis with useful lives ranging from 11 years to 13 years, which is based on the remaining number of years the assets are expected to economically contribute to the business. The pro forma financial information has not been presented for DTE Energy because the effects of the acquisition were not material to the Consolidated Statements of Operations.
In conjunction with the above acquisition, DTE Sustainable Generation closed on a purchase and sale agreement with Heritage Sustainable Energy in January 2020 to acquire an additional renewable energy project for approximately $33 million paid in cash.

Gas Storage and Pipelines Segment Acquisition
On December 4, 2019, DTE Energy closed on the purchase of midstream natural gas assets in support of its strategy to continue to grow and earn competitive returns for shareholders. DTE Energy purchased 100 percent of M5 Louisiana Gathering, LLC and its wholly owned subsidiaries from Momentum Midstream and Indigo Natural Resources. The acquisition includes the Blue Union and LEAP assets which provide natural gas gathering and other midstream services to producers located primarily in Louisiana.
The fair value of the consideration provided for the entities acquired was $2.74 billion and includes $2.36 billion paid in cash and an estimated $380 million of contingent consideration to be paid upon completion of a gathering pipeline in the second half of 2020. The contingent payment will range from $0 million to $385 million, with no payment due until the pipeline is completed. As of March 31, 2020, the liability for the contingent consideration payment and the related accretion expense of $2 million is included in the 'Acquisition related deferred payment' line in the Consolidated Statements of Financial Position. The acquisition was financed through the issuance of Equity Units, common stock, and Senior Notes. The acquired assets are part of DTE Energy's non-utility Gas Storage and Pipelines segment.
The acquisition was accounted for using the acquisition method of accounting for business combinations. The allocation of the purchase price included in the Consolidated Statements of Financial Position is preliminary and may be revised up to one year from the date of acquisition due to adjustments in the estimated fair value of the assets acquired and the liabilities assumed. The purchase price is subject to (i) final working capital settlement adjustments, and (ii) resolution of any indemnification claims that might be deducted from the $100 million of cash consideration paid and held in escrow.
The excess purchase price over the fair value of net assets acquired was classified as goodwill. As of March 31, 2020, total goodwill was approximately $173 million, including $2 million resulting from working capital adjustments recorded during the first quarter of 2020. DTE Energy cannot estimate the potential for any further revisions to the purchase price allocation for the remainder of 2020.
The factors contributing to the recognition of goodwill are based on various strategic benefits that are expected to be realized from the Blue Union and LEAP acquisition. The acquisition will provide DTE Energy with a platform for midstream growth and access to further investment opportunities in the Haynesville basin. The goodwill is expected to be deductible for income tax purposes.
The preliminary allocation of the purchase price is based on estimated fair values of the Blue Union and LEAP assets acquired and liabilities assumed at the date of acquisition, December 4, 2019. The components of the preliminary purchase price allocation, inclusive of purchase accounting adjustments, are as follows:

Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

The intangible assets recorded as a result of the acquisition pertain to existing customer relationships, which were valued at approximately $1.47 billion as of the acquisition date. The fair value of the intangible assets acquired was estimated by applying the income approach. The income approach is based upon discounted projected future cash flows attributable to the existing contracts and agreements. The fair value measurement is based on significant unobservable inputs, including management estimates and assumptions, and thus represents a Level 3 measurement, pursuant to the applicable accounting guidance. Key estimates and inputs include revenue and expense projections and discount rates based on the risks associated with the entities. The intangible assets are amortized on a straight-line basis over a period of 40 years, which is based on the number of years the assets are expected to economically contribute to the business. The expected economic benefit incorporates existing customer contracts with a weighted-average amortization life of 13 years and expected renewal rates, based on the estimated volume and production lives of gas resources in the region.
DTE Energy incurred $18 million of direct transaction costs for the year ended December 31, 2019. These costs were primarily related to advisory fees and were included in Operation and maintenance in DTE Energy's Consolidated Statements of Operations. Additionally, DTE Energy incurred $49 million of issuance costs related to the acquisition financing, of which $10 million were included in Mortgage bonds, notes, and other, and $39 million were included in Common Stock in DTE Energy's Consolidated Statements of Financial Position.
DTE Energy's 2019 Consolidated Statements of Operations included Operating Revenues — Non-utility operations of $15 million and Net Income of $3 million associated with the acquired entities for the one-month period following the acquisition date, excluding the $18 million transaction costs described above. The pro forma financial information was not presented for DTE Energy because the effects of the acquisition were not material to the Consolidated Statements of Operations.

NOTE 56 — REGULATORY MATTERS
2018 Electric Rate Case Filing2020 COVID-19 Response
DTE Electric filed a rate case withIn response to the MPSC on July 6, 2018 requesting an increase in base rates of $328 million based on a projected twelve-month period ending April 30, 2020. The requested increase in base rates was primarily due to an increase in net plant resulting from infrastructure investments, depreciation expense, as requested in the 2016 DTE Electric Depreciation Case Filing, and reliability improvement projects. The rate filing also requested an increase in return on equity from 10.0% to 10.5% and included projected changes in sales, operation and maintenance expenses, and working capital. In addition, the rate filing requested an Infrastructure Recovery Mechanism to recover the incremental revenue requirement associated with certain distribution, fossil generation, and nuclear generation capital expenditures through 2022. Finally, as noted in the 2017 Tax Reform section below, DTE Electric proposed an amortization schedule for Calculation C in this filing. On February 1, 2019, DTE Electric reduced its initial requested increase in base rates to $248.6 million, primarily reflecting the reduction in requested depreciation expense resulting from the MPSC's approval of new depreciation rates. On May 2, 2019,COVID-19 pandemic, the MPSC issued an order approving an annual revenue increaseon April 15, 2020 to provide guidance and direction to utilities and other stakeholders on topics including customer protections and affordability, utility accounting, regulatory activities, energy assistance, and energy waste reduction and demand response continuity.  The order authorizes the deferral of $125 millionuncollectible expense that is in excess of the amount used to set current rates effective March 24, 2020, the date of Michigan's executive order to "Stay Home, Stay Safe".  The Registrants are currently evaluating the impact of this order for services renderedpotential change in accounting treatment, and will continue to monitor MPSC activities for further guidance on or after May 9, 2019. The MPSC authorized a return on equity of 10.0%. In addition, the order approved the proposed amortization schedule for Calculation C but denied the requested Infrastructure Recovery Mechanism.COVID-19 and any other pandemic related costs.
2019 Electric Rate Case Filing
DTE Electric filed a rate case with the MPSC on July 8, 2019 requesting an increase in base rates of $351 million based on a projected twelve-month period ending April 30, 2021. The requested increase in base rates is primarily due to an increase in net plant resulting from infrastructure and generation investments. The rate filing also requests an increase in return on equity from 10.0% to 10.5% and includes projected changes in sales and operating and maintenance expenses. A final MPSC order in this case is expected by May 2020.

DTE ElectricGas filed a depreciationrate case with the MPSC on November 1, 201625, 2019 requesting an increase in depreciationbase rates forof $204 million based on a projected twelve-month period ending September 30, 2021.  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 requests an increase in service balances as of December 31, 2015. The MPSC issued an orderreturn on December 6, 2018 authorizing DTE Electricequity from 10.0% to increase its composite depreciation rate from 3.06% to 3.72%. The new rates are effective for service rendered on or after May 9, 2019, per the final order in DTE Electric's 2018 rate case issued on May 2, 2019.
2017 Tax Reform
On December 27, 2017, the MPSC issued an order to consider10.5% and includes projected changes in the rates of all Michigan rate-regulated utilities to reflect the effects of the federal TCJA. On January 19, 2018, DTE Electricsales and DTE Gas filed information with the MPSC regarding the potential change in revenue requirements due to the TCJA effective January 1, 2018 and outlined their recommended method to flow the current and deferred tax benefits of those impacts to ratepayers.

Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

On February 22, 2018, the MPSC issued an order in this case requiring utilities, including DTE Electric and DTE Gas, to follow a 3-step approach of credits and calculations. In 2018, MPSC orders for the first two steps, Creditworking capital.  A and Credit B, were issued for DTE Electric and DTE Gas. The third step is to perform Calculation C to address all remaining issues relative to the new tax law, which is primarily the remeasurement of deferred taxes and how the amounts deferred as Regulatory liabilities will flow to ratepayers. DTE Gas filed its Calculation C case on November 16, 2018 to reduce the annual revenue requirement by $12 million related to the amortization of deferred tax remeasurement and a final MPSC order in this case is expected by August 2019.

NOTE 67 — EARNINGS PER SHARE
Basic earnings per share is calculated by dividing the 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 and stock options do not receive cash dividends; as such, these awards are not considered participating securities.

NOTE 78 — 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, 2019March 31, 2020 and December 31, 2018.2019. The Registrants believe they use valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

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.

(b)At June 30,March 31, 2020 and December 31, 2019, the $11 million consisted of cash equivalents included in Other investments on DTE Electric's Consolidated Statements of Financial Position. At December 31, 2018, the $10 million consisted of cash equivalents included in Other investments on DTE Electric's Consolidated Statements of Financial Position.
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 are valued using quoted market prices in actively traded markets. Commingled funds that hold exchange-traded equity or debt securities are valued based on stated NAVs. Non-exchange-tradedNon-exchange traded fixed income securities are valued based upon quotations available from brokers or pricing services. Other
Private equity and other assets such as private equity investmentsinclude a diversified group of funds that are classified as NAV assets. AThese funds primarily invest in private equity partnerships, as well as real estate and private debt. 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 $151 million as of March 31, 2020 and December 31, 2019, respectively.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

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 price 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.

Derivatives are transferred between levels primarily due to changes in the source data used to construct price curves as a result of changes in market liquidity. Transfers in and transfers out are reflected as if they had occurred at the beginning of the period.
There were no transfers between Levels 1 and 2 for the Registrants during the three and six months ended June 30, 2019 and 2018, and there were no transfers from or into Level 3 for DTE Electric during the same periods.three months ended March 31, 2020 and 2019.

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 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 resulthave resulted in a higher (lower) fair value for long positions, with offsetting impacts to short positions.

Other Securities
At June 30, 2019 and December 31, 2018, the Registrants' securities, included in Other investments on the Consolidated Statements of Financial Position, were comprised primarily of money market and equity securities. For the three months ended June 30, 2019 and 2018, gains related to equity securities were $7 million and $1 million, respectively. For the six months ended June 30, 2019, gains related to equity securities were $24 million and losses related to equity securities held at June 30, 2018 were $1 million for the Registrants. Gains or losses related to the Rabbi Trust assets are allocated from DTE Energy to DTE Electric.

NOTE 89 — 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 portion of the derivative gain or loss that is effective in offsetting the change in the value of the underlying exposure is deferred in Accumulated other comprehensive income (loss) and later reclassified into earnings when the underlying transaction occurs. Gains or losses from the ineffective portion of cash flow hedges are recognized in earnings immediately. 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 coalenvironmental contracts, forwards, futures, options, swaps, and foreign currency exchange contracts. Items not classified as derivatives include natural gas and environmental inventory, pipeline transportation contracts, renewable energy credits,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, buys and sells transportation capacity, and sells storage and transportation capacity. DTE Gas has fixed-priced contracts for portions of its expected natural gas supply requirements through March 2022.2023. Substantially all of these contracts meet the normal purchases and normal sales exception and are therefore accounted for under the accrual method. DTE Gas may also sell forward transportation and storage capacity contracts. Forward transportation and storage contracts are generally not derivatives and are therefore accounted for under the accrual method.
Gas Storage and Pipelines — This segment is primarily engaged in services related to the gathering, transportation, and storage of natural gas. Primarily fixed-priced contracts are used in the marketing and management of transportation and storage services. Generally, these contracts are not derivatives and are therefore accounted for under the accrual method.
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.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

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.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

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, 2019March 31, 2020 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 $5$9 million and $4 million outstanding at June 30, 2019March 31, 2020 and December 31, 2018,2019, 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 $2$5 million and $8 million at June 30, 2019March 31, 2020 and December 31, 2018,2019, 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, 2019,March 31, 2020, 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 $541$381 million.
As of June 30, 2019,March 31, 2020, DTE Energy had $493$676 million of derivatives in net liability positions, for which hard triggers exist. There is $4 million0 of 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 $395$601 million. The net remaining amount of $94$75 million is derived from the $541$381 million noted above.

NOTE 1112 — LEASES
Disclosures relatedLessor
During the first quarter of 2020, DTE Energy completed construction of and began operating certain energy infrastructure assets for a large industrial customer under a long-term agreement, where the assets will transfer to the six months ended June 30, 2019 are presented as required under Topic 842. Prior period disclosures forcustomer at the year ended December 31, 2018 are presented under Topic 840. The Registrants have elected to use a practical expedient provided by Topic 842 whereby comparative disclosures for prior periods are allowed to be presented under Topic 840. Prior period disclosures under Topic 840 have been provided on an annual basis. As a result, the disclosures presented under Topic 842 and Topic 840 will not be fully comparable in specific disclosure requirements or time period.
Lessee
Topic 842 — Leases at DTE Energy are primarily comprised of various forms of equipment, computer hardware, coal railcars, production facilities, buildings, and certain easement leases with terms ranging from approximately 2 to 40 years. Leases at DTE Electric are primarily comprised of various forms of equipment, computer hardware, coal railcars, and certain easement leases with terms ranging from approximately 2 to 40 years.
A lease is deemed to exist when the Registrants have the right to control the use of identified property, plant or equipment, as conveyed through a contract, for a certain period of time and consideration paid. The right to control is deemed to occur when the Registrants have the right to obtain substantially allend of the economic benefits of the identified assets and the right to direct the use of such assets.
Lease liabilities are determined utilizing a discount rate to determine the present values of lease payments. Topic 842 requires the use of the rate implicitcontract term in the lease when it is readily determinable. When the rate implicit in the lease is not readily determinable, the incremental borrowing rate is used. The Registrants have determined their respective incremental borrowing rates based upon the rate of interest that would have been paid on a collateralized basis over similar tenors to that of the leases. The incremental borrowing rates for DTE Electric and DTE Gas have been determined utilizing respective secured borrowing rates for first mortgage bonds with like tenors of remaining lease terms. Incremental borrowing rates for non-utility entities have been determined utilizing an implied secured borrowing rate based upon an unsecured rate for a similar tenor of remaining lease terms, which is then adjusted for the estimated impact of collateral.

Topic 842 — DTE Energy leases a portion of its pipeline system to the Vector Pipeline through a 20-year finance lease contract that expires in 2020, with renewal options extending for five years each. DTE Energy owns a 40% interest in the Vector Pipeline. In addition, DTE Energy has an energy services agreement that expires in 2026, of which a portion is accounted for as a finance lease.
DTE Energy also leases various assets under operating leases for a pipeline, energy facilities and related equipment. Such leases are comprised of both fixed payments and variable payments which are contingent on volumes, with terms ranging from 3 to 24 years. Generally, the operating leases do not have renewal provisions or options to purchase the assets at the end of the lease. The operating leases generally do not have termination for convenience provisions. Termination may be allowed under specific circumstances stated in the lease contract, such as under an event of default.
Certain of the finance and operating leases have lease terms that extend to the end of the estimated economic life of the leased assets, thereby resulting in no residual value. Any remaining residual values under the finance and operating leases are expected to be recovered through rates, renewals or new lease contracts. Residual values have been determined using the estimated economic life of the leased assets. The finance and operating leases do not contain residual value guarantees.
Certain of the operating leases have both lease and non-lease components. The lease and non-lease components are allocated based upon estimated relative standalone selling prices.
A lease is deemed to exist when the Registrants have provided other parties with the right to control the use of identified property, plant or equipment, as conveyed through a contract, for a certain period of time and consideration received. The right to control is deemed to occur when the Registrants have provided other parties with the right to obtain substantially all of the economic benefits of the identified assets and the right to direct the use of such assets.

NOTE 1213 — 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 SO2 and 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 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.
In July 2009, the Registrants received a NOV/FOV from the EPA alleging, among other things, that five5 DTE Electric power plants violated New Source Performance standards, Prevention of Significant Deterioration requirements, and operating permit requirements under the Clean Air Act. In June 2010, the EPA issued a NOV/FOV making similar allegations related to a project and outage at Unit 2 of the Monroe Power Plant. In March 2013, DTE Energy received a supplemental NOV from the EPA relating to the July 2009 NOV/FOV. The supplemental NOV alleged additional violations relating to the New Source Review provisions under the Clean Air Act, among other things.
In August 2010, the U.S. Department of Justice, at the request of the EPA, brought a civil suit in the U.S. District Court for the Eastern District of Michigan against DTE Energy and DTE Electric, related to the June 2010 NOV/FOV and the outage work performed at Unit 2 of the Monroe Power Plant. In August 2011, the U.S. District Court judge granted DTE Energy's motion for summary judgment in the civil case, dismissing the case and entering judgment in favor of DTE Energy and DTE Electric. In October 2011, the EPA filed a Notice of Appeal to the Court of Appeals for the Sixth Circuit. In March 2013, the Court of Appeals remanded the case to the U.S. District Court for review of the procedural component of the New Source Review notification requirements. In September 2013, the EPA filed a motion seeking leave to amend their complaint regarding the June 2010 NOV/FOV adding additional claims related to outage work performed at the Trenton Channel and Belle River Power Plants as well as additional claims related to work performed at the Monroe Power Plant. In March 2014, the U.S. District Court judge again granted DTE Energy's motion for summary judgment dismissing the civil case related to Monroe Unit 2. In April 2014, the U.S. District Court judge granted motions filed by the EPA and the Sierra Club to amend their New Source Review complaint adding additional claims for Monroe Units 1, 2, and 3, Belle River Units 1 and 2, and Trenton Channel Unit 9. In October 2014, the EPA and the U.S. Department of Justice filed a notice of appeal of the U.S. District Court judge's dismissal of the Monroe Unit 2 case. The amended New Source Review claims were all stayed pending resolution of the appeal by the Court of Appeals for the Sixth Circuit. On January 10, 2017, a divided panel of the Court reversed the decision of the U.S. District Court. On May 8, 2017, DTE Energy and DTE Electric filed a motion to stay the mandate pending filing of a petition for writ of certiorari with the U.S. Supreme Court. The Sixth Circuit granted the motion on May 16, 2017, staying the claims in the U.S. District Court until the U.S. Supreme Court disposes of the case. DTE Electric and DTE Energy filed a petition for writ of certiorari on July 31, 2017. On December 11, 2017, the U.S. Supreme Court denied certiorari. As a result of the Supreme Court electing not to review the matter, the case was sent back to the U.S. District Court for further proceedings and on June 14, 2018 the case was stayed pending settlement negotiations. The proceedings at the District Court remain stayed until May 2020 while the parties discuss potential resolution of the matter.
The Registrants believe that the plants and generating units identified by the EPA and the Sierra Club have complied with all applicable federal environmental regulations. Depending upon the outcome of the litigation and further discussions with the EPA regarding the two2 NOVs/FOVs, DTE Electric could be required to install additional pollution control equipment at some or all of the power plants in question, implement early retirement of facilities where control equipment is not economical, engage in supplemental environmental programs, and/or pay fines. The Registrants do not expect the outcome forof this matter to have a material impact on their Consolidated Financial Statements.

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 Affordable Clean Energy (ACE)ACE rule. The ACE Rule requires the state of Michigan to submit a plan in 2022 that includes GHG standards for existing coal-fired power plant units in Michigan. These final rules do not impact DTE Energy's revised goalcommitments for its electric utility operations to reduce carbon emissions 32% by the early 2020s, 50% by 2030, and 80% by 2040, or its goal of net 0 emissions for its electric utility operations by 2050, from the 2005 carbon emissions levels.
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 spent approximately $2.4 billion through 2018.2019. DTE Electric does not anticipate additional capital expenditures for air pollution requirements through 2025.2026, 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 National Pollutant Discharge Elimination System (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 three3 former MGP sites. 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 aboveground 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, 2019March 31, 2020 and December 31, 2018,2019, DTE Electric had $8 million and $7 million, respectively, accrued for remediation. 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 and July 2018. Additionally, D.C. District Court DecisionsThe rule is based on August 21, 2018 and March 19, 2019 may affect the timing of closurecontinued listing of coal ash impoundments that are not lined with an engineered liner system. In 2019, the EPA is expected to affirmatively undertake rulemaking to implement the D.C. District Court's decisions that will determine any changes to DTE Electric's plans in the operationas a non-hazardous waste and closure of coal ash impoundments.
At the State level, legislation was signed by the Governor in December 2018. The bill provides for a CCR program to be regulated in Michigan once approval is requestedrelies on various self-implementation design and received from the EPA.

DTE Electric owns and operates three3 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.plants subject to certain provisions in the CCR obligations vary based on plant life, but includerule. At certain facilities, the rule currently requires the installation of monitoring wells, compliance with groundwater standards, and the closure of landfills and basins at the end of the useful life of the associated power plant or as a basin becomes inactive. Underplant. At other facilities, the rule requires ash laden waters be moved from earthen basins to steel and concrete tanks. DTE Electric has estimated the impact of the current rule to be $592 million of capital expenditures.
On December 2, 2019 a proposed revision to the CCR rules and uncertainty regardingRule was published in the Federal Register to address the D.C. District CourtCircuit's 2018 decision capital costsregarding CCR impoundments that are not lined with an engineered liner system. The rule proposes that all CCR impoundments that do not meet the engineered liner requirements must close by specific dates, and timing associated withit further confirms that all clay lined impoundments are viewed as unlined. On March 3, 2020 an additional proposed revision to the buildingCCR Rule was published in the Federal Register that provides a process to determine if certain unlined impoundments consist of newan alternative liner system that may be as protective as the current liners specified in the CCR facilities or retirementrule, and therefore may continue to operate. DTE Electric is currently evaluating options including the alternative liner system demonstration for our clay lined impoundments based on the range of existingoutcomes of the current proposed rules to determine any changes to DTE Electric's plans in the operation and closure of coal ash impoundments.
At the State level, legislation was signed by the Governor in December 2018 and provides for further regulation of the CCR facilities are being evaluated.program in Michigan. Additionally, the bill provides the basis of a CCR program that EGLE will submit to the EPA for approval to fully regulate the CCR program in Michigan in lieu of a Federal permit program.
In November 2015, the EPA finalized the ELG Rule for the steam electric power generating industry which requires additional controls to be installed between 2018 and 2023. Compliance schedules for individual facilities and individual waste streams are determined through issuance of new National Pollutant Discharge Elimination System (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. 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 ELG Rule’s compliance deadlines for fly ash transport water, bottom ash transport water, and flue gas desulfurization (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 November 22, 2019, the EPA issued a proposed rule to revise the technology-based effluent limitations guidelines and standards applicable to flue gas desulfurization wastewater and bottom ash transport water. The ELG compliance requirements and final deadlines for bottom ash transport water and FGD wastewater, and total ELG related compliance costs will not be known until the EPA completes its reconsideration of the ELG Rule expected by the end of 2019.2020.
DTE Gas
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 seven8 of the MGP sites is complete, and the sites are closed. DTE Gas has also completed partial closure of seven4 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, 2019March 31, 2020 and December 31, 2018,2019, DTE Gas had $27$24 million and $25 million, respectively, accrued for remediation. 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 environmentalthe 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 a finding of violation 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 the Michigan Department of Environment, Great Lakes, and Energy (formerly known as the Michigan Department of Environmental Quality)EGLE did not comply with the Clean Air Act. DTE Energy is currently evaluatingEES Coke evaluated the EPA's alleged violations and believes that the permits approved by EGLE complied with the Clean Air Act. Discussions with the EPA are ongoing. At the present time, DTE Energy cannot predict the outcome or financial impact or outcome of this matter.FOV.
Other
In 2010, the EPA finalized a new one-hour SO2 ambient air quality standard that requires states to submit plans and associated timelines for non-attainment areas that demonstrate attainment with the new SO2 standard in phases. Phase 1 addresses non-attainment areas designated based on ambient monitoring data. Phase 2 addresses non-attainment areas with large sources of SO2 and modeled concentrations exceeding the National Ambient Air Quality Standards for SO2. Phase 3 addresses smaller sources of SO2 with modeled or monitored exceedances of the new SO2 standard.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

Michigan's Phase 1 non-attainment area includes DTE Energy facilities in southwest Detroit and areas of Wayne County. Modeling runs by the MDEQEGLE suggest that emission reductions may be required by significant sources of SO2 emissions in these areas, including DTE Electric power plants and DTE Energy's Michigan coke battery facility. As part of the state implementation plan (SIP) process, DTE Energy has worked with the MDEQEGLE to develop air permits reflecting significant SO2 emission reductions that, in combination with other non-DTE Energy sources' emission reduction strategies, will help the state attain the standard and sustain its attainment. Since several non-DTE Energy sources are also part of the proposed compliance plan, DTE Energy is unable to determine the full impact of the final required emissions reductions on DTE's facilities at this time.
Michigan's Phase 2 non-attainment area includes DTE Electric facilities in St. Clair County. State implementation plan (SIP) submittal and EPA approval describing the control strategy and timeline for demonstrating compliance with the new SO2 standard is the next step in the process and is expected to be completed by the end of 2019. DTE Energy is currently working with the MDEQ to develop the required SIP.in 2020. DTE Energy is unable to determine the full impact of the SIP strategy.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements (Unaudited) — (Continued)

DTE Electric participates in various plans that provide pension and other postretirement benefits for DTE Energy and its affiliates. The plans are sponsored by DTE Energy's subsidiary, DTE Energy Corporate Services, LLC. DTE Electric accounts for its participation in DTE Energy's qualified and nonqualified 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 nonqualified pension benefit costs. DTE Electric's allocated portion of pension benefit costs included in capital expenditures and operating and maintenance expense were $22$26 million and $30$23 million for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively, and $45 million and $60 million for the six months ended June 30, 2019 and 2018, respectively. These amounts include recognized contractual termination benefit charges, curtailment gains, and settlement charges.
The following tables detail the components of net periodic benefit costs (credits) for other postretirement benefits for DTE Electric:

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:

The decrease in Net Income for the secondfirst quarter was primarily due to lower earnings in the Electric Gas, Gas Storage and Pipelines, and Power and Industrial Projects segments, partially offset by higher earnings in the Corporate and Other segment. The decrease in Net Income for the six-month period was primarily due to lower earnings in the Electric, Gas Storage and Pipelines, and Power and Industrial Projects segments, partially offset by higher earnings in the Gas Storage and CorporatePipelines segment.
During the first quarter 2020, the COVID-19 pandemic began impacting Michigan and the other service territories throughout the United States in which the Registrants operate. DTE Energy has taken certain safety precautions, including directing employees to work remotely whenever possible and pausing all non-critical construction projects. DTE Energy has complied with Michigan and other states' "stay-at-home" orders, which require employees to stay home unless their work is necessary to sustain or protect life, such as providing safe and reliable energy.
The spread of COVID-19 and efforts to contain the virus have resulted in closures and reduced operations of businesses, governmental agencies, and other institutions. This has also contributed to disruption and volatility in the financial markets. For certain non-qualified benefit plan trusts for which gains and losses affect earnings, this impact to financial markets resulted in pre-tax investment losses of $31 million for the Electric segment and $3 million for the Gas segment for the three months ended March 31, 2020.
Other segments.impacts from the COVID-19 pandemic have included decreased demand within the Electric segment, which contributed to lower base sales for the quarter, and lower production within the Power and Industrial Projects segment, due to certain customers reducing their operations. The allowance for doubtful accounts was also increased for our utility customers. These impacts were not material to the Registrants' financial results for the three months ended March 31, 2020.
Please see detailed explanations of segment performance in the following "Results of Operations" section.
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.
In March 2019,

DTE Energy announced updated plans for accelerating its reduction ofis committed to reduce the carbon emissions toof its electric utility operations by 32% by the early 2020s, at least 50% by 2030, and 80% by 2040 from the 2005 carbon emissions levels. DTE Energy is also committed to a net zero carbon emissions goal by 2050 for its electric utility operations. To achieve thisthe 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. 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. DTE Energy expects growth opportunities in the Gas Storage and Pipelines and Power and Industrial Projects segments.
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.


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 2019-20232020-2024 period are estimated at $11.3$12.0 billion comprised of $4.0 billion for capital replacements and other projects, $4.6$5.0 billion for distribution infrastructure, and $2.7$3.0 billion for new generation. DTE Electric has retired five coal-fired generation units at the Trenton Channel, River Rouge, and St. Clair facilities and has announced plans to retire its remaining twelve coal-fired generating units. Six of these coal-fired generating units will be retired through 2022 at the Trenton Channel, River Rouge, and St. Clair facilities. The remaining coal-fired generating units at the Belle River and Monroe facilities are expected to be retired by 2040. The retired facilities will be replaced with renewables, energy waste reduction, demand response, and natural gas fueled generation.
DTE Gas' capital investments over the 2019-20232020-2024 period are estimated at $2.5$3.0 billion comprised of $1.2$1.4 billion for base infrastructure, and $1.3$1.6 billion for gas main renewal, meter move out, and pipeline integrity programs.
DTE Electric and DTE Gas plansplan 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. Gas Storage and Pipelines' capital investments over the 2019-20232020-2024 period are estimated at $4.0$2.2 billion to $5.0$2.7 billion for gathering and pipeline investments and expansions. Power and Industrial Projects' capital investments over the 2019-20232020-2024 period are estimated at $1.0 billion to $1.4 billion for industrial energy services and RNG projects.
ENVIRONMENTAL MATTERS
The Registrants are subject to extensive environmental regulation.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 1213 to the Consolidated Financial Statements, "Commitments and Contingencies."


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.
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.
In the near term, DTE Energy will continue to monitor the impact of the COVID-19 pandemic on supply chains, markets, counterparties, and customers, and any related impacts on the operating costs, customer demand, and recoverability of assets in our business segments that could materially impact the Registrants financial results. At this time, the Registrants cannot predict the ultimate impact of these factors to our Consolidated Financial Statements, as future developments involving the severity of COVID-19, actions to contain or treat its impact, and the extent to which normal economic and operating conditions can resume are highly uncertain.
DTE Energy will also monitor and evaluate the impact of any regulatory and legislative activities related to the COVID-19 pandemic, including the MPSC order on April 15, 2020 which authorized the deferral of certain uncollectible expenses. Refer to Note 6 to the Consolidated Financial Statements, "Regulatory Matters," for further detail regarding the order.

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.
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 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.

Operating Revenues - Non-utility operations increased $4 million in the three months ended March 31, 2020 due to renewable energy projects acquired by DTE Sustainable Generation in September 2019.
Operation and maintenance expense decreased $7 million and increased $33$4 million in the three and six months ended June 30, 2019, respectively.March 31, 2020. The decrease in the second quarterincrease was primarily due to the deferral of previously accrued expenses for the new customer billing system approved in the 2018 rate order received on May 2, 2019 of $11 million. The increase in the six-month period was primarily due to increased distribution operations$10 million higher generation expense, of $12 million, insurance proceeds from a 2016 fire at a generation facility received in 2018 of $8 million, an increase in energy waste reduction expense of $6 million, an increase in renewable energy expense of $4 million, and higher customer service expense of $8 million, partially offset by the deferral$6 million of previously accrued expenses for the new customer billing system approved in the 2018 rate order received on May 2, 2019 of $11 million.lower benefit costs.
Depreciation and amortization expense increased $27 million and $36$40 million in the three and six months ended June 30, 2019, respectively.March 31, 2020. The increase in the second quarter was primarily due to an increase of $32 million ina higher utility depreciable base of $47 million and the change in deprecation rates effective in May 2019,a $3 million increase resulting from new non-utility assets at DTE Sustainable Generation, partially offset by a decrease of $5$10 million associated with the TRM. The increase in the six-month period was primarily due to an increase of $47 million in depreciable base and the change in deprecation rates effective in May 2019, partially offset by a decrease of $9 million associated with the TRM.
Asset (gains) losses and impairments, net increased $13 million for both the three and six months ended June 30, 2019. The increase was due to previously recorded capital expenditures of $13 million that were disallowed in the May 2, 2019 rate order.
Other (Income) and Deductions decreased $1 million and $19increased $59 million in the three and six months ended June 30, 2019, respectively.March 31, 2020.

Income Tax Expense decreased $19 million and $37$16 million in the three and six months ended June 30, 2019, respectively. The decrease in the second quarter wasMarch 31, 2020 primarily due to lower earnings and amortization of the TCJA regulatory liability. The decrease in the six-month period was primarily due to lower earnings, amortization of the TCJA regulatory liability, and $8 million of true-up adjustments for the remeasurement of deferred tax assets and liabilities in 2018.
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.


DTE Electric filed a rate case with the MPSC on July 8, 2019 requesting an increase in base rates of $351 million based on a projected twelve-month period ending April 30, 2021. The requested increase in base rates is primarily due to an increase in net plant resulting from infrastructure and generation investments. The rate filing also requests an increase in return on equity from 10.0% to 10.5% and includes projected changes in sales and operating and maintenance expenses. A final MPSC order in this case is expected by May 2020. Refer to Note 56 to the Consolidated Financial Statements, "Regulatory Matters" for additional information.

Net Income Attributable to Noncontrolling Interests decreased $3 million and $4 million in the three and six months ended June 30, 2019, respectively.March 31, 2020. The decrease in both periods was primarily due to the May 2019 purchase of an additional 30% ownership interest in SGG.
See Note 4 to the Consolidated Financial Statements, "Acquisitions," for discussion of the acquisition of Blue Union and LEAP in December 2019.
Outlook — Significant expansion activities are underway to increase capacity of the Blue Union and LEAP assets, which provide natural gas gathering and other midstream services to producers located primarily in Louisiana.
DTE Energy believes its long-term agreements with producers and the quality of the natural gas reserves in the Marcellus/Utica regionand Haynesville shale regions soundly position the gathering systemsbusiness for future revenues.
The NEXUS Pipeline provides a transportation path for Appalachian Basin shale gas, including Utica and Marcellus shale gas, directly to consuming markets in northern Ohio, southeastern Michigan, and Dawn Ontario. DTE Energy owns a 50% partnership interest in the NEXUS Pipeline.
On January 11, 2019, NEXUS signed an agreement to purchase Generation Pipeline, LLC, a public utility regulated by the Public Utilities Commission of Ohio. This 23-mile pipeline system supplies gas to industrial customers in the Toledo, OH area, has existing interconnects with ANR Pipeline Company and Panhandle Eastern Pipeline Company, and is located 4 miles away from NEXUS. The transaction is expected to close in 2019 upon regulatory approvals.
AGS and SGG provide a platform for midstream growth and access to further investment opportunities in the Appalachian basin, an additional connection to the NEXUS Pipeline which should drive incremental volumes on the NEXUS Pipeline, and producer relationships that may lead to more partnering opportunities.
Gas Storage and Pipelines expects to maintain its steady growth by developing an asset portfolio with multiple growth platforms through investment in new projects and expansions. Gas Storage and Pipelines will continue to lookexecute quality investments, with a focus on continued organic growth from well-positioned existing assets.
Recent declines in commodity prices can have a negative impact on customers of Gas Storage and Pipelines if sustained for additional investment opportunitiesan extended period. DTE Energy continues to work with its customers by executing short, medium, and otherlong-term storage, gathering, and pipeline projects at favorable prices.transportation contracts.
Gas Storage and Pipelines is also monitoring the impacts of the COVID-19 pandemic on future operations and financial results. Refer to the "Executive Overview" and "Outlook" sections above for DTE Energy's consideration of COVID-19 impacts on our business segments.

Outlook — In the near-term, Energy Trading expects market conditions to remain challenging, and thechallenging. 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, and physical power and natural gas contracts, and certain environmental contracts are deemed derivatives,derivatives; whereas, natural gas and environmental inventory, contracts for pipeline transportation, renewable energy credits,storage assets, and storage assetssome 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 78 and 89 to the Consolidated Financial Statements, "Fair Value" and "Financial and Other Derivative Instruments," respectively.
Energy Trading is also monitoring the impacts of the COVID-19 pandemic on future operations and financial results. Refer to the "Executive Overview" and "Outlook" sections above for DTE Energy's consideration of COVID-19 impacts on our business segments.
CORPORATE AND OTHER
Corporate and Other includes various holding company activities, holds certain non-utility debt, and holds energy-related investments. The net loss of $32 million and $35$11 million for the three and six months ended June 30, 2019, respectively,March 31, 2020 represents a decreasean increase of $9 million and $27$8 million from the net lossesloss of $41 million and $62$3 million in the comparable 20182019 period. The net loss decrease in the second quarterincrease was primarily due to effective income tax rate adjustments, partially offset by higher interest expense. For the six-month period, the decrease was primarily due to effective income tax rate adjustments and higherlower excess tax benefits on stock-based compensation partially offset by higher interest expense.and effective income tax rate adjustments.

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 20192020 will be approximately $2.4$3.0 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 20192020 of approximately $3.9$4.5 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.

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.
CashNet cash from operations decreasedincreased by $66$309 million in 20192020. The increase is primarily due primarily to a decreasean increase in cash flow from working capital items partially offset byand an increase in Depreciation and amortization expense.Deferred income taxes.
The change in working capital items in 20192020 was primarily related to an increasea decrease in cash used for accountsAccounts payable, regulatory assetsAccrued pension costs, and liabilities, and otherOther current and noncurrent assets and liabilities, partially offset by an increase in cash from accounts receivableused for Regulatory assets and accrued pension liability.liabilities and Inventories.
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.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.


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 increased by $134$594 million in 20192020 primarily due primarily to the increase inhigher Plant and equipment expenditures — utility and Notes Receivable, partially offset bynew acquisitions, as described in Note 4 to the decrease in Contributions to equity method investees and Plant and equipment expenditures — non-utility.Consolidated Financial Statements.
Cash from (used for) 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 $189$883 million in 20192020 primarily due primarily to an increase in Issuanceissuance of long-term debt and the reduction of Redemption of long-termshort-term debt, partially offset by thean increase in repaymentsredemptions of Short-term borrowings and Purchases of noncontrolling interests, principally related to SGG.long-term debt.


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, primarily in the Gas Storage and Pipelines and Power and Industrial Projects segments.
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.
DTE Energy has approximately $1.5$0.4 billion in long-term debt, including finance leases, maturing in the next twelve months. The repayment of the debt is expected to be paid through internally generated funds or the issuance of unsecured term loans or long-term debt.
DTE Energy has approximately $2.4$2.5 billion of available liquidity at June 30, 2019,March 31, 2020, consisting of cash, and amounts available under unsecured revolving credit agreements.agreements, and unsecured term loans.
At the discretion of management and depending upon economic and financial market conditions, DTE Energy expects to issue equity up to $250$300 million in 20192020. If issued, DTE Energy anticipates up to $185 million of these equity issuances will be made through the pension and other employee benefit plans, which is exclusive from any amounts relatedcontributions to the Equity Units described in Note 14qualified pension plans, including $160 million of DTE Electric contributions. DTE Energy does not anticipate making any contributions to the Consolidated Financial Statements, "Long-Term Debt," within the combined DTE Energy and DTE Electric 2018 Annual Report on Form 10-K. For contribution amounts related to pensionother postretirement plans refer to Note 13 of the Consolidated Financial Statements, "Retirement Benefits and Trusteed Assets."



in 2020.
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, and coal) and the provisions and maturities of the underlying transactions. As of June 30, 2019,March 31, 2020, 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 $541$381 million.
In April 2020, Fitch Ratings downgraded DTE Energy's unsecured debt rating from BBB+ to BBB. The downgrade primarily reflects increased leverage and business risk associated with DTE Energy's acquisition of midstream natural gas assets in December 2019. Refer to Note 4 to the Consolidated Financial Statements, "Acquisitions," for additional information. We do not expect the downgrade to negatively impact DTE Energy's liquidity or access to the capital markets.
DTE Energy is also actively monitoring the impact of the COVID-19 pandemic on capital markets and any related effects to our cost of capital. During the three months ended March 31, 2020, concerns over the pandemic led to a lack of liquidity in the commercial paper market and increases to related borrowing costs. Despite these impacts, the Registrants have maintained adequate liquidity due to the availability of committed credit facilities and by raising additional liquidity through term loans and the public issuance of utility debt, while paying off maturing commercial paper.
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 5, 9,6, 10, 12,11, 13, and 1314 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.
NEW ACCOUNTING PRONOUNCEMENTS
See Note 3 to the Consolidated Financial Statements, "New Accounting Pronouncements."


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, oil,some environmental contracts, and certain coal 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, renewable energy credits,storage assets, and storage assets.some environmental contracts. See Notes 78 and 89 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 renewable energy creditssome 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 78 to the Consolidated Financial Statements, "Fair Value."

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 Gas Storage and Pipelines segment has exposure to natural gas price fluctuations which impact the pricing for natural gas storage, gathering, and transportation. DTE Energy manages its exposure through the use of short, medium, and long-term storage, gathering, and transportation contracts.
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, coal,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 pre-determined risk parameters.
Credit Risk
Bankruptcies
DTE Energy's Power and Industrial Projects segment holds ownership interests in, and operates, five generating plants that sell electric output from renewable sources under long-term power purchase agreements with PG&E. PG&E filed for Chapter 11 bankruptcy protection on January 29, 2019. As of June 30, 2019,March 31, 2020, PG&E's&Es account is substantially current and outstanding accounts receivable from PG&E are not material. Therefore, DTE Energy determined no reserve was necessary.
As of June 30, 2019,March 31, 2020, the book value of long-lived assets and operating lease right-of-use assets used in producing electric output for sale to PG&E was approximately $103$100 million. The Power and Industrial Projects segment also has equity investments, including a note receivable, of approximately $73$69 million in entities that sell power to PG&E. In January 2019, following the bankruptcy filing, DTE Energy performed an impairment analysis on its long-lived assets. Based on its undiscounted cash flow projections, DTE Energy determined it did not have an impairment loss as of December 31, 2018. DTE Energy also determined there was not an other-than-temporary decline in its equity investments. There were no other new events occurring during the six months ended June 30, 2019,DTE has not identified subsequent facts or circumstances that would negatively impact the assumptions made within the Decembercause a change to these conclusions through March 31, 2018 impairment analysis. Therefore, no triggering events were identified.2020. DTE Energy's assumptions and conclusions may change, and it could have impairment losses if any of the terms of the contracts are not honored by PG&E or the contracts are rejected through the bankruptcy process.
OtherAllowance for Doubtful Accounts
The Registrants regularly review contingent matters 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.


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, 2019:March 31, 2020:

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 London Inter-Bank Offered Rates (LIBOR).LIBOR. As of June 30, 2019,March 31, 2020, DTE Energy had a floating rate debt-to-total debt ratio of 0.02%6.10%.
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 2023.2024.

Part II — Other Information
Item 1. Legal Proceedings
In March 2018, the Trenton Channel Power Plant experienced exceedances of its mercury emission limits. The exceedances were reported to the EPA and the MDEQ. On September 12, 2018, the EPA issued a NOV. On June 28, 2019, DTE Electric entered into a Consent Agreement and Final Order (CAFO) with the EPA to resolve the allegations in the NOV. Under the CAFO, DTE Electric agreed to pay a civil penalty in the amount of $25,133 and to spend $95,000 on environmental projects that will benefit the Grosse Ile School District and the City of Trenton.
For more information on legal proceedings and matters related to the Registrants, see Notes 56 and 1213 to the Consolidated Financial Statements, "Regulatory Matters" and "Commitments and Contingencies," respectively.

Item 1A. Risk Factors
There are various risks associated with the operations of the Registrants' businesses. To provide a framework to understand the operating environment of the Registrants, a brief explanation of the more significant risks associated with the Registrants' businesses is provided in Part 1, Item 1A. Risk Factors in DTE Energy's and DTE Electric's combined 20182019 Annual Report on Form 10-K. Although the Registrants have tried to identify and discuss key risk factors, others could emerge in the future.For the three months ended March 31, 2020, one additional risk factor was identified as noted below:

The COVID-19 pandemic and resulting impact on business and economic conditions could negatively affect the Registrants' businesses and operations. The COVID-19 pandemic is currently impacting countries, communities, supply chains and markets. The continued spread of COVID-19 and efforts to contain the virus, such as quarantines or closures or reduced operations of businesses, governmental agencies and other institutions, has caused an economic slowdown, and could lead to a recession, result in significant disruptions in various public, commercial or industrial activities and cause employee absences which could interfere with operation and maintenance of the Registrants' facilities. Travel bans and restrictions, quarantines, and shelter-in-place orders (including those in effect in our service areas in the State of Michigan) could also cause us to experience operational delays, delay the delivery of critical infrastructure and other supplies we source globally, delay the connection of electric or gas service to new customers, and significantly reduce the use of electricity and gas by our customers. We have experienced lower sales volumes in some operating segments, and any of the foregoing circumstances could further adversely affect customer demand or revenues, impact the ability of the Registrants' suppliers, vendors or contractors to perform, or cause other unpredictable events, which could adversely affect the Registrants' businesses, results of operations or financial condition. The continued spread of COVID-19 has also led to disruption and volatility in the financial markets, which could increase the Registrants' costs to fund capital requirements and impact the operating results of our energy trading operations. To the extent that the Registrants' access to the capital markets is adversely affected by COVID-19, the Registrants may need to consider alternative sources of funding for our operations and for working capital, any of which could increase the Registrants' cost of capital. The extent to which COVID-19 may impact the Registrants' liquidity, financial condition, and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including new information concerning the severity of COVID-19 and the actions taken to contain it or treat its impact, and the extent to which normal economic and operating conditions can resume, among others. Our business continuity plans and insurance coverage may be insufficient to mitigate these adverse impacts to our business. In addition, the Registrants’ decision to suspend shut-offs for certain customers may adversely impact the Registrants’ collections process, which could have a negative impact on our results of operations, financial condition, and liquidity.
