REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


June 20, 2016


To the Participants, Benefit Plan Administration Committee, and Investment Committee
DTE Gas Company Investment and Stock Ownership Plan

We have audited the accompanying statements of net assets available for benefits of the DTE Gas Company Investment and Stock Ownership Plan (the “Plan”) as of December 31, 2015 and 2014, and the related statement of changes in net assets available for benefits for the year ended December 31, 2015. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2015 and 2014, and the changes in net assets available for benefits for the year ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America.

The schedule of assets (held at end of year) as of December 31, 2015, referred to as “supplementary information,” has been subjected to audit procedures performed in conjunction with the audits of the Plan’s financial statements. The supplementary information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplementary information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplementary information. In forming our opinion on the supplementary information, we evaluated whether the supplementary information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, as amended. In our opinion, the supplementary information is fairly stated, in all material respects, in relation to the financial statements as a whole.

DTE Gas Company Investment and Stock Ownership Plan

Notes to Financial Statements


NOTE 1 - PLAN DESCRIPTION
The following description of the DTE Gas Company Investment and Stock Ownership Plan (the Plan), provides only general information. Participants should refer to the Summary Plan Description and the Plan Document for a more complete description of the Plan's provisions.
General
The Plan is a voluntary, defined contribution plan for regular full-time or part-time employees of DTE Gas Company (DTE Gas or the Company) represented by:
Local #799C Transmission and Storage Operations (T&SO), International Chemical Workers Union Council, United Food and Commercial Workers;
Local #799C Northern, International Chemical Workers Union Council, United Food and Commercial Workers;
Local #70C, International Chemical Workers Union Council, United Food and Commercial Workers; or
Local #132C, International Chemical Workers Union Council, United Food and Commercial Workers
Employees are eligible to participate as soon as administratively practicable upon hire. The Plan is subject to certain provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA).
The Plan is sponsored solely by DTE Energy Corporate Services, LLC (DTE LLC).The DTE Energy Benefit Plan Administration Committee (BPAC) is the administrator of the Plan (Plan Administrator). The Plan Administrator has the responsibility for the day-to-day administration of the Plan. DTE LLC, acting through the DTE Energy Investment Committee, is responsible for the selection and retention of the Plan's investment options and any investment manager that may be appointed under the DTE Energy Master Plan Trust (Master Trust). Great-West Trust Company, LLC is the Plan Trustee (Trustee), and Empower Retirement is the Plan recordkeeper (Recordkeeper).
Investment management fees, brokerage fees, transfer taxes, and other expenses incidental to the purchase or sale of securities are paid from investment assets. These expenses are reflected as a reduction in the fair value of the funds.
Contributions
A participant may contribute to the Plan on a pre-tax (Tax Deferred Contributions), post-tax (Employee After-tax Contributions), Roth 401(k) Contributions, and, if applicable, a catch-up contribution basis (Catch-Up Contributions and Roth 401(k) Catch-Up Contributions). Participants age 50 or older in the Plan year are eligible to make Catch-Up Contributions and Roth 401(k) Catch-Up Contributions in accordance with, and subject to the limitations of, Section 414(v) of the Internal Revenue Code of 1986, as amended (IRC). Participants may contribute up to 100% of eligible compensation (as defined in the Plan) on a combined Tax Deferred Contributions, Employee After-tax Contributions, Roth 401(k) Contributions, and Catch-Up Contributions (if applicable) basis, after required tax withholdings and mandatory and voluntary payroll deductions. Tax Deferred Contributions, Employee After-tax Contributions, Roth 401(k) Contributions, and Catch-Up Contributions are automatically adjusted downward if the full deferral amounts elected cannot be taken. Participants may also directly roll over into the Plan distributions of certain assets from a tax-qualified plan of a prior employer, including Roth 401(k) Rollover (Direct Rollover Contributions).
The IRC limits the amount of Tax Deferred Contributions, Roth 401(k) Contributions, Catch-Up Contributions, and Roth 401(k) Catch-Up Contributions which may be contributed to the Plan annually. These amounts are indexed for inflation annually. In the event a Plan participant's Tax Deferred Contributions reach the maximum amount permitted by the IRC, further contributions for the remainder of the Plan year will automatically be deemed to be Employee After-tax Contributions. If a participant's total annual additions (Tax Deferred Contributions, Employee After-tax Contributions, Roth 401(k) Contributions, and Company Contributions) reach the IRC limit for the Plan year, the participant's contributions will be stopped or refunded, as applicable.

DTE Gas Company Investment and Stock Ownership Plan

Notes to Financial Statements (Continued)


For Local #70C, #132C, #799C Northern participants, and Local #799C T&SO participants, Company Contributions are 100% of the first 4% of the aggregate of Tax Deferred Contributions, Employee After-tax Contributions, and Roth 401(k) Contributions, and 50% of the next 4% of the aggregate of Tax Deferred Contributions, Employee After-tax Contributions, and Roth 401(k) Contributions. There are no Company Contributions for Tax Deferred Contributions, Employee After-tax Contributions, and Roth 401(k) Contributions which in the aggregate exceed 8% of basic compensation. The Company also provides a longevity award, equal to $600 in DTE Energy common stock, which is contributed annually in March of each year to the DTE Energy Stock Fund accounts of employees with 30 years of service or more as of March 1 and who do not meet the IRC definition of a highly compensated employee.
For new hires on or after June 6, 2011, in addition to the Company Contributions noted above for Local #70C, #132C, and #799C Northern participants, the Company will make the following Non-Elective Contributions, which are not eligible for loans or other withdrawals while the participant is actively employed:
(1)
For each pay period an amount equal to 4% of the participant's compensation; plus
(2)
For the first pay period that begins after the date participant completes one year of service as an eligible participant, $1,400; plus
(3)
For each pay period beginning after the pay period that begins after the eligible participant completes one year of service, an additional amount equal to 4% of the participant's compensation.
(4)
Beginning as of March 27, 2013, these participants are treated as having elected to increase their pay reduction agreement by 1% of his or her eligible compensation to make before-tax contributions as of the first pay period in each plan year with a pay date after May 31, unless:
a.
The participant's pay reduction agreement in effect on May 31 is for at least 10% of the participant's eligible compensation; or
b.
The participant makes an affirmative election after the first day of the plan year and no later than May 31 of the plan year to not have this increase apply as of the first pay period in that plan year with a pay date after May 31. An election applies only to the plan year in which the election was made and not to any subsequent plan year.
For new hires on or after March 27, 2013, in addition to the Company Contributions noted above for Local #799C T&SO participants, the Company will make Non-Elective Contributions each pay period in an amount equal to 4% of the participant's compensation, which is not eligible for loans or other withdrawals while the participant is actively employed.
(1)
These participants are treated as having elected to increase their pay reduction agreement by 1% of his or her eligible compensation to make before-tax contributions as of the first pay period in each plan year with a pay date after May 31, unless:
a.
The participant's pay reduction agreement in effect on May 31 is for at least 10% of the participant's eligible compensation; or
b.
The participant makes an affirmative election after the first day of the plan year and no later than May 31 of the plan year to not have this increase apply as of the first pay period in that plan year with a pay date after May 31. An election applies only to the plan year in which the election was made and not to any subsequent plan year.

Notes to Financial Statements (Continued)


The Company will contribute $5,000 to the Employer Special Contribution account of a participant who satisfies these requirements:
(1)
The participant must:
a.
be employed by DTE Gas; and
b.
have a Termination of Service after August 2, 2013 and:
i.
before March 28, 2017 if the participant is represented by Local #70C, #132C, and #799 Northern; or
ii.
before October 10, 2017 if the participant is represented by Local #799C T&SO; and
(2)
As of the date of the participant's Termination of Service, the participant must satisfy any of the following age and service requirements for a defined benefit pension or postretirement healthcare plan formula under which the participant has an accrued benefit as of the date of the participant's Termination of Service:
a.
DTE Cash Balance Plan or DTE Traditional Plan:
i.
Age 65; or
ii.
Age 45 with at least 15 years of Eligibility Service.
b.
MCN Cash Balance Plan or MCN Traditional Plan:

ii.
At least 30 years of Eligibility Service.
c.
DTE Energy Company Comprehensive Retiree Group Health Care Plan:
i.     Age 45 with at least 10 Years of Service.
(3)
The Employer Special Contribution will be made as soon as practicable after the participant's Termination of Service. Employer Special Contributions made are treated as Company Contributions for all Plan purposes other than vesting in Company Contributions. These contributions are fully vested at all times. These contributions will be reduced before any other contributions are refunded or suspended.
Catch-Up Contributions and Roth 401(k) Catch-Up Contributions are not eligible for Company Contributions.
While the Company has made its contributions to the Trustee with respect to a plan year on a current basis, the Plan permits the Company to make Company Contributions for a plan year no later than the due date (including extensions of time) for filing DTE Energy Company's consolidated federal income tax return for such year. Tax Deferred Contributions and Employee After-tax Contributions are paid to the Plan when amounts can be reasonably segregated. The Company expects to continue to make Plan contributions on a current basis.
Participant Accounts
Each participant's account is credited with the participant's contributions, including eligible Direct Rollover Contributions, Company Contributions, Non-Elective Contributions, and investment earnings. Forfeited balances of terminated participants' non-vested accounts are used to reduce future Company Contributions. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

Notes to Financial Statements (Continued)


Vesting
Tax Deferred Contributions, Employee After-tax Contributions, Roth 401(k) Contributions, Catch-Up Contributions, Roth 401(k) Catch-Up Contributions, and Direct Rollover Contributions are fully vested at all times. A participant vests in all Company Contributions and Non-Elective Contributions according to the following schedule:
Years of Service
 
Percent Vested
Less than 2 years
 
0%
2
 
20%
3
 
40%
4
 
60%
5
 
80%
6
 
100%
In addition, a participant will have a fully vested interest in Company Contributions and Non-Elective Contributions upon (a) attainment of age 65, (b) termination due to total disability, if entitled to benefits under the Company's Long Term Disability Benefits Plan, (c) death, (d) termination of the Plan, or (e) in some cases, in connection with the sale of a business.
Investment Options
Participants may elect to have their Tax Deferred Contributions, Employee After-tax Contributions, Roth 401(k) Contributions, Catch-Up Contributions, Roth 401(k) Catch-Up Contributions, and Direct Rollover Contributions invested entirely in any one of the investment funds or in any combination of the investment funds. Participants may transfer existing account balances in the investment funds on a daily basis. Participants may change their investment direction and amount of future contributions effective with the next payroll period.
The Company Contribution and Non-Elective Contributions will be initially invested in the DTE Energy Stock Fund. The Company Contribution and Non-Elective Contribution will be made either in cash or in shares of DTE Energy common stock at the option of DTE LLC. If the Company Contribution or Non-Elective Contribution is made in cash, the DTE Energy Stock Fund will immediately purchase shares of DTE Energy common stock on the open market. Participants can elect to transfer Company Contributions and Non-Elective Contributions from the DTE Energy Stock Fund to one or more investments at any time.
The entire DTE Energy Stock Fund is considered to be the Employee Stock Ownership Plan (ESOP) portion of the Plan. Quarterly dividends from DTE Energy common stock are automatically reinvested in DTE Energy common stock. DTE Energy common stock dividends may be paid out in cash on a quarterly basis, at the participant's election.
Contributions received by the Trustee for the DTE Energy Stock Fund are invested in DTE Energy common stock. The Trustee currently purchases and sells shares of DTE Energy common stock in open market transactions at prevailing market prices. However, the Trustee may purchase or sell DTE Energy common stock from or to DTE Energy if the purchase or sale price is for adequate consideration. Brokerage commissions are charged against the DTE Energy Stock Fund.
A participant's interest in the DTE Energy Stock Fund is measured by share trading. A share-traded investment is traded and valued on a share basis.
Administrative and Brokerage Fees
A participant’s account balance will be charged with certain fees and expenses. Asset-based fees (e.g., investment management fees and other operating expenses) are used to cover expenses related to running an investment fund, and are generally deducted directly from a participant’s investment returns. Participant fees relating to participation in the Master Trust's Self Directed Account are included in individual transactions within that account.
For the DTE Energy Stock Fund, brokerage, commission, and other fees connected with the purchase and sale of securities are paid by participants who have invested in the fund.
Plan administration fees cover the day-to-day expenses of administering the Plan. These costs are paid fully by the Company. Transaction-based fees also may be charged with respect to optional features offered under the Plan (e.g., loans), and are charged directly against a participant’s account balance.

Voting Rights
Each participant is entitled to exercise voting rights attributable to the shares of DTE Energy common stock allocated to his or her account and is notified by the Trustee prior to the time that such rights are to be exercised. Shares with respect to which the Trustee does not receive voting instructions will be voted by the Trustee in the same proportion as shares for which the Trustee receives voting instructions.
Distributions, Withdrawals, and Loans
Distributions of Tax Deferred Contributions will be made only upon retirement or disability, as defined under the Plan, termination of employment, death, attainment of age 59 1/2, or hardship. A hardship distribution of Tax Deferred Contributions (but generally not the earnings thereon) is permitted only for (a) medical expenses, (b) tuition expenses, (c) expenditures to purchase a principal residence, (d) payments to prevent eviction or foreclosure on a principal residence, (e) payment of funeral expenses, or (f) payment of expenses for the repair of damage to the participant's principal residence due to casualty loss.
Participants may borrow funds from their accounts attributable to Tax Deferred Contributions, Employee After-tax Contributions (if applicable), Catch-Up Contributions, Direct Rollover Contributions, Roth 401(k) Contributions, and Roth 401(k) Catch-Up Contributions not more than once during any calendar year. The number of loans outstanding at one time is limited to two, only one of which may be a principal residence loan.
Subject to certain terms and conditions, a participant may initiate a general purpose loan for a period of one to five years, and a principal residence loan for a period up to 25 years, at a fixed rate equal to the prime interest rate plus 1%, updated monthly, at a minimum of $1,000 up to the lesser of:
$50,000 reduced by (a) the highest outstanding balance of loans from the Plan during the one-year period ending on the day before the loan was made, over (b) the outstanding balance of loans from the Plan on the date the loan is made, or
50% of the participant's account at the time the loan is made.
Proceeds for any loan are obtained through the pro rata liquidation of the participant's account, then transferred to the participant's loan account and paid in cash to the participant by the Trustee. Loan repayments of principal and interest are invested as received according to the participant's current investment direction. Prepayment of loans can be made without penalty provided such prepayment is made in full.
Plan Termination
Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA, except as otherwise agreed to pursuant to collective bargaining. In the event of Plan termination, participants will become 100% vested in their accounts.
Plan Amendments
There were no significant plan amendments in 2015.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Accounting
The accompanying financial statements of the Plan are prepared on the accrual basis of accounting.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires Plan management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions to and deductions from net assets available for benefits during the reporting period. Actual results could differ from those estimates.

DTE Gas Company Investment and Stock Ownership Plan

Notes to Financial Statements (Continued)


Valuation of Investments and Income Recognition
Investments are reported at fair value. Fair value is 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.
Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) includes the Plan’s net gains and losses on investments bought and sold as well as held during the year.
The DTE Energy Stock Fund recognizes gains or losses on stock distributed to terminated participants in settlement of their accounts equal to the difference between the cost and the fair value of the shares distributed.
Notes Receivable from Participants
Notes receivable from participants are valued at cost plus accrued interest and are secured by a portion of the participant's account balance as collateral. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be in default, the participant loan balance is reduced, and a benefit payment is recorded. No allowance for credit losses has been recorded as of December 31, 2015 and 2014.
Payment of Benefits
Benefits are recorded when paid.
Risks and Uncertainties
The Master Trust invests in various securities, including short-term investments, equity funds, fixed income funds, target date funds, and Company common stock. Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term, and such changes could materially affect participants’ account balances and the amounts reported in the financial statements.
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 Plan makes certain assumptions it believes that market participants would use in pricing assets or liabilities, including assumptions about risk and the risks inherent in the inputs to valuation techniques. The Plan believes it uses valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

9


DTE Gas Company Investment and Stock Ownership Plan

Notes to Financial Statements (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 Plan classifies 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 Plan has 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.

NOTE 3 — FEDERAL INCOME TAX STATUS
The Plan obtained its latest determination letter on April 2, 2015 in which the Internal Revenue Service (IRS) stated that the Plan, as then designed, was in compliance with the applicable requirements of the IRC. The Plan is qualified under Sections 401(a) and 401(k) of the IRC. The Plan Administrator is not aware of any unrecognized tax benefits as of December 31, 2015 or 2014. Accordingly, no provision for income taxes has been included in the accompanying financial statements. The Plan is no longer subject to federal income tax examinations by the IRS for years prior to 2012.

NOTE 4 — THE DTE ENERGY MASTER PLAN TRUST
The Master Trust consists of certain commingled assets of the Plan, the DTE Energy Company Savings and Stock Ownership Plan, the DTE Electric Company Savings & Stock Ownership Plan for Employees Represented by Local 17 of the International Brotherhood of Electrical Workers, and the DTE Electric Company Savings & Stock Ownership Plan for Employees Represented by Local 223 of the Utility Workers Union of America.
The Plan’s investment in the Master Trust in the Statements of Net Assets Available for Benefits represents the Plan’s allocated portion (approximately 3% at December 31, 2015 and 2014, respectively). The Plan’s allocated portion of the investments is equal to the fair value of the Plan’s assets contributed, adjusted by the Plan’s allocated share of the Master Trust investment income and expenses, Participant and Employer Contributions, and Distributions and withdrawals.
