Explanatory Note

        FS Energy and Power Fund, or the Company, which may also be referred to as "we," "us" or "our," is filing this Amendment No. 1 (the "Amendment") to its Annual Report on Form 10-K for the Company's fiscal year ended December 31, 2017, as originally filed with the Securities and Exchange Commission (the "SEC") on March 7, 2018 (the "Original Report"). The purpose of this Amendment is to include Part III information, which was to be incorporated by reference from the Company's definitive proxy statement for the 2018 Annual Meeting of Shareholders. This information was previously omitted from the Original Report in reliance on General Instruction G(3) to Form 10-K, which would permit the Part III information to be incorporated in the Original Report by reference from the Company's definitive proxy statement if such proxy statement is filed no later than 120 days after the fiscal year-end. The Company is filing this Amendment to include Part III information in the Annual Report on Form 10-K for the year ended December 31, 2017 because a definitive proxy statement containing such information will not be filed by the Company within 120 days after the end of the fiscal year covered by the Original Report. This Amendment also updates, amends and supplements Part IV, Item 15 of the Form 10-K to include the filing of new Exhibits 31.1 and 31.2, certifications of our Chief Executive Officer and Chief Financial Officer, pursuant to Rule 13a-14(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). In addition, the cover page has been updated and amended.

        The Amendment does not affect any other items in the Original Report, including the Company's financial statements and the notes to the financial statements. Except as otherwise indicated, the Amendment speaks as of the date of the Original Report and reflects only the changes discussed above. Accordingly, this Amendment should be read in conjunction with the Original Report.

Item 10.    Trustees, Executive Officers and Corporate Governance.

Board of Trustees

        The role of the Company's board of trustees (the "Board") is to provide general oversight of the Company's business affairs and to exercise all of the Company's powers except those reserved for the shareholders. The responsibilities of the Board also include, among other things, the oversight of the Company's investment activities, the quarterly valuation of the Company's assets, oversight of the Company's financing arrangements and corporate governance activities.

        The Board is currently comprised of eight trustees, six of whom are not "interested persons," as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended (the "1940 Act"), of the Company or FS/EIG Advisor, LLC, the Company's investment adviser (the "Advisor"), and are "independent" as defined in Rule 5605(a)(2) of The NASDAQ Stock Market LLC. These individuals are referred to as the Company's independent trustees (the "Independent Trustees"). Section 2(a)(19) of the 1940 Act defines an "interested person" to include, among other things, any person who has, or within the last two years had, a material business or professional relationship with the Company. The members of the Board who are not Independent Trustees are referred to as interested trustees (the "Interested Trustees").

Item 11.    Executive Compensation.

Compensation Discussion and Analysis

        The Company's executive officers do not receive any direct compensation from the Company. The Company does not currently have any employees and does not expect to have any employees. As an externally managed business development company, or BDC, services necessary for the Company's business are provided by individuals who are employees of the Advisor or its affiliates or by individuals who were contracted by the Company or the Advisor or their respective affiliates to work on behalf of the Company, pursuant to the terms of the investment advisory and administrative services agreement between the Company and the Advisor, dated April 9, 2018, or the FS/EIG investment advisory and administrative services agreement. Each of the Company's executive officers is an employee of the Advisor or its affiliates or an outside contractor, and the day-to-day investment operations and administration of the Company's portfolio are managed by the Advisor. In addition, the Company will reimburse the Advisor for the Company's allocable portion of expenses incurred by the Advisor in performing its obligations under the FS/EIG investment advisory and administrative services agreement. Historically, the Company reimbursed FS Investment Advisor, LLC, or FS Investment Advisor, pursuant to an investment advisory and administrative services agreement between the Company and FS Investment Advisor, dated April 28, 2011, as amended by the First Amendment to the Investment Advisory and Administrative Services Agreement, dated August 10, 2012, or the FSIA investment advisory and administrative services agreement. The FSIA investment advisory and administrative services agreement was replaced by the FS/EIG investment advisory and administrative services agreement.

Trustee Compensation

        The Company does not pay compensation to its trustees who also serve in an executive officer capacity for the Company or the Advisor. Trustees who do not also serve in an executive officer capacity for the Company or the Advisor are entitled to receive annual cash retainer fees, fees for participating in quarterly Board and Board committee meetings and certain other Board and Board committee meetings and annual fees for serving as a committee chairperson, determined based on the Company's net assets as of the end of each fiscal quarter. These trustees are Messrs. Brown, Chandler, Goldstein, Pizzi, Vague and Williams. Mr. Goldstein also receives an annual retainer for his service as lead Independent Trustee.

        Amounts payable under the trustee fee arrangement were determined and paid quarterly in arrears as follows:

        The Company also reimburses each of the above trustees for all reasonable and authorized business expenses in accordance with its policies as in effect from time to time, including reimbursement of reasonable out-of-pocket expenses incurred in connection with attending each in-person Board meeting and each in-person Board committee meeting not held concurrently with a Board meeting.

Item 13.    Certain Relationships and Related Transactions, and Trustee Independence.

Certain Relationships and Related Party Transactions (dollar amounts in thousands, excluding per share amounts, unless otherwise noted)

        The Company has procedures in place for the review, approval and monitoring of transactions involving the Company and certain persons related to the Company. For example, the Company's Code of Business Conduct and Ethics generally prohibits any employee, officer or trustee from engaging in any transaction where there is a conflict between such individual's personal interest and the interests of the Company. Waivers to the Code of Business Conduct and Ethics for any executive officer or member of the Board must be approved by the Board and are publicly disclosed as required by applicable law and regulations. In addition, the Audit Committee is required to review and approve all transactions with related persons (as defined in Item 404 of Regulation S-K promulgated under the Exchange Act). Prior to the occurrence of a liquidity event (which could include (1) a listing of the Company's Shares on a national securities exchange, (2) the sale of all or substantially all of the Company's assets either on a complete portfolio basis or individually followed by a liquidation or (3) a merger or another transaction approved by the Board in which the Company's shareholders likely will receive cash or shares of a publicly-traded company), all future transactions with affiliates of the Company will be on terms no less favorable than could be obtained from an unaffiliated third party and must be approved by a majority of the Board, including a majority of the Independent Trustees.

Compensation of the Investment Adviser and Dealer Manager

        Historically, we received investment advisory and administrative services from FS Investment Advisor pursuant to the FSIA investment advisory and administrative services agreement. The FSIA investment advisory and administrative services agreement was replaced by the FS/EIG investment advisory and administrative services agreement between the Company and the Advisor, a newly-formed entity that is jointly owned by FS Investment Advisor and EIG Global Energy Partners. FS Investment Advisor previously engaged GSO Capital Partners, L.P. ("GSO") to act as the Company's investment sub-adviser pursuant to the investment sub-advisory agreement between FS Investment Advisor and GSO, dated April 28, 2011, or the GSO sub-advisory agreement. GSO resigned as the Company's investment sub-adviser and terminated the investment sub-advisory agreement effective April 9, 2018.

        Pursuant to the FS/EIG investment advisory and administrative services agreement, the Advisor is entitled to an annual base management fee based on the average weekly value of the Company's gross assets (equal to the total assets set forth on the Company's consolidated financial statements) and an incentive fee based on the Company's performance. The base management fee is calculated at an annual rate of 1.75% of the average weekly value of the Company's gross assets. The base management fee is payable quarterly in arrears and is calculated based on the average weekly value of the Company's gross assets during the most recently completed calendar quarter. The incentive fee consists of two parts. The first part of the incentive fee, which is referred to as the subordinated incentive fee on income, is calculated and payable quarterly in arrears, equals 20.0% of the Company's "pre-incentive fee net investment income" for the immediately preceding quarter and is subject to a hurdle rate, expressed as a rate of return on adjusted capital, equal to 1.625% per quarter, or an annualized hurdle rate of 6.5%. As a result, the Advisor will not earn this incentive fee for any quarter until the Company's pre-incentive fee net investment income for such quarter exceeds the hurdle rate of 1.625%. For purposes of the subordinated incentive fee on income, "adjusted capital" means cumulative gross proceeds generated from sales of the Company's Shares (including proceeds from the Company's distribution reinvestment plan) reduced for distributions from non-liquidating dispositions of the Company's investments paid to shareholders and amounts paid for share repurchases pursuant to the Company's share repurchase program. Once the Company's pre-incentive fee net investment income in any quarter exceeds the hurdle rate, the Advisor will be entitled to a "catch-up" fee equal to the amount of the Company's pre-incentive fee net investment income in excess of the hurdle rate, until the Company's pre-incentive fee net investment income for such quarter equals 2.031%, or 8.125% annually, of adjusted capital. Thereafter, the Advisor will be entitled to receive 20.0% of the Company's pre-incentive fee net investment income.

        The second part of the incentive fee, which is referred to as the incentive fee on capital gains, is determined and payable in arrears as of the end of each calendar year (or upon termination of the

FS/EIG investment advisory and administrative services agreement). This fee equals 20.0% of the Company's "incentive fee capital gains" (which equals the Company's realized capital gains on a cumulative basis from inception, calculated as of the end of the applicable period, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis), less the aggregate amount of any previously paid incentive fees on capital gains. The Company will accrue for the incentive fee on capital gains, which, if earned, will be paid annually. The Company will accrue the incentive fee on capital gains based on net realized and unrealized gains; however, under the terms of the FS/EIG investment advisory and administrative services agreement, the fee payable to the Advisor will be based on realized gains and no such fee will be payable with respect to unrealized gains unless and until such gains are actually realized.

        Pursuant to the FS/EIG investment advisory and administrative services agreement, the Advisor oversees our day-to-day operations, including the provision of general ledger accounting, fund accounting, legal services, investor relations, certain government and regulatory affairs activities and other administrative services. The Advisor also performs, or oversees the performance of, our corporate operations and required administrative services, which includes being responsible for the financial records that we are required to maintain and preparing reports for our shareholders and reports filed with the SEC. Pursuant to the FS/EIG investment advisory and administrative services agreement, the Company reimburses the Advisor no less than monthly for expenses necessary to perform services related to the Company's administration and operations. The amount of this reimbursement is set at the lesser of (1) the Advisor's actual costs incurred in providing such services and (2) the amount that the Company estimates it would be required to pay alternative service providers for comparable services in the same geographic location. The Advisor allocates the cost of such services to the Company based on factors such as assets, revenues, time allocations and/or other reasonable metrics consistent with past practice (but solely to the extent such past practice is not inconsistent with the policies of the Advisor). The Company does not reimburse the Advisor for any services for which it receives a separate fee, or for rent, depreciation, utilities, capital equipment or other administrative items allocated to a controlling person of the Advisor.

        Historically, pursuant to the FSIA investment advisory and administrative services agreement, FS Investment Advisor was entitled to an annual base management fee of 2.0% of the average weekly value of the Company's gross assets and an incentive fee based on the Company's performance. Pursuant to the GSO sub-advisory agreement, GSO received 50% of all management and incentive fees payable to FS Investment Advisor under the FSIA investment advisory and administrative services agreement with respect to each year. Effective January 1, 2018 FS Investment Advisor contractually agreed to permanently waive 0.25% of its base management fee to which it was entitled under the FSIA investment advisory and administrative services agreement, so that the fee received equaled 1.75% of the average weekly value of the Company's gross assets.

        The Company also reimbursed FS Investment Advisor for expenses necessary to perform services related to the Company's administration and operations, including FS Investment Advisor's allocable portion of the compensation and related expenses of certain personnel of FS Investments, the Company's sponsor and an affiliate of FS Investment Advisor, providing administrative services to the Company on behalf of FS Investment Advisor. The amount of this reimbursement for FS Investment Advisor was set at the lesser of (1) FS Investment Advisor's actual costs incurred in providing such services and (2) the amount that the Company estimated it would be required to pay alternative service providers for comparable services in the same geographic location. FS Investment Advisor allocated the cost of such services to the Company based on factors such as assets, revenues, time allocations and/or other reasonable metrics.

        Also, under the FSIA investment advisory and administrative services agreement, the Company, either directly or through reimbursement to FS Investment Advisor or its affiliates, was responsible for its organization and offering costs in an amount up to 1.5% of gross proceeds raised in the Company's continuous public offering. Organization and offering costs primarily included legal, accounting, printing and other expenses relating to the Company's continuous public offering, including costs associated with technology integration between the Company's systems and those of its selected broker-dealers, marketing expenses, salaries and direct expenses of FS Investment Advisor's personnel, employees of its affiliates and others while engaged in registering and marketing the Shares, which included the

development of marketing materials and presentations, training and educational meetings, and generally coordinating the marketing process for the Company.

        Prior to satisfaction of the minimum offering requirement and for a period of time thereafter, FS Investments funded certain of the Company's organization and offering costs. Following this period, the Company has paid certain of its organization and offering costs directly and reimbursed FS Investment Advisor for offering costs incurred by FS Investment Advisor on the Company's behalf, including marketing expenses, salaries and other direct expenses of FS Investment Advisor's personnel and employees of its affiliates while engaged in registering and marketing the Shares. Organization and offering costs funded directly by FS Investments were recorded by the Company as a contribution to capital. The offering costs were offset against capital in excess of par value on the consolidated financial statements and the organization costs were charged to expense as incurred by the Company. All other offering costs, including costs incurred directly by the Company, amounts reimbursed to FS Investment Advisor for ongoing offering costs and any reimbursements paid to FS Investments for organization and offering costs previously funded, are recorded as a reduction of capital. Commencing January 1, 2016, offering costs incurred by the Company were deferred and amortized to expense over twelve months. Following the closing of the Company's continuous public offering to new investors in November 2016, all deferred offering costs were expensed.

        During the year ended December 31, 2017, FS Investments did not fund any of the Company's organization and offering costs. As of December 31, 2017, no amounts remain reimbursable to FS Investment Advisor and its affiliates under this arrangement.

        The dealer manager for the Company's continuous public offering was FS Investment Solutions, LLC ("FS Investment Solutions"), which is one of the Company's affiliates. Prior to the closing of the Company's continuous public offering in November 2016, the dealer manager was entitled under the dealer manager agreement, by and among the Company, FS Investment Advisor and FS Investment Solutions, or the dealer manager agreement, to receive selling commissions and dealer manager fees in connection with the sale of Shares in the Company's continuous public offering, all or a portion of which could be re-allowed to selected broker-dealers. The dealer manager agreement terminated in connection with the closing of the Company's continuous public offering in November 2016.

        The following table describes the fees and expenses the Company accrued under the FSIA investment advisory and administrative services agreement and the dealer manager fees FS Investment

Expense Reimbursement

        Historically, pursuant to the expense support and conditional reimbursement agreement, dated as of May 16, 2013, by and between FS Investments and the Company, or the expense reimbursement agreement, FS Investments agreed to reimburse the Company for expenses in an amount that was sufficient to ensure that no portion of the Company's distributions to shareholders were paid from its offering proceeds or borrowings. However, because certain investments the Company may have made, including preferred and common equity investments, may have generated dividends and other distributions to the Company that were treated for tax purposes as a return of capital, a portion of the Company's distributions to shareholders may also have been deemed to constitute a return of capital to the extent that the Company used such dividends or other distribution proceeds to fund its distributions to shareholders. Under those circumstances, FS Investments would not reimburse the Company for the portion of such distributions to shareholders that represented a return of capital, as the purpose of the expense reimbursement arrangement was not to prevent tax-advantaged distributions to shareholders.

        Under the expense reimbursement agreement, FS Investments reimbursed the Company for expenses in an amount equal to the difference between the Company's cumulative distributions paid to its shareholders in each quarter, less the sum of the Company's net investment company taxable income, net capital gains and dividends and other distributions paid to the Company on account of preferred and common equity investments in portfolio companies (to the extent such amounts were not included in net investment company taxable income or net capital gains) in each quarter.

        Pursuant to the expense reimbursement agreement, the Company had a conditional obligation to reimburse FS Investments for any amounts funded by FS Investments under such agreement if (and only to the extent that), during any fiscal quarter occurring within three years of the date on which FS Investments funded such amount, the sum of the Company's net investment company taxable income, net capital gains and the amount of any dividends and other distributions paid to the Company on account of preferred and common equity investments in portfolio companies (to the extent not included in net investment company taxable income or net capital gains) exceeded the regular cash distributions paid by the Company to its shareholders; provided, however, that (i) the Company would only reimburse FS Investments for expense support payments made by FS Investments with respect to any calendar quarter to the extent that the payment of such reimbursement (together with any other reimbursement paid during such fiscal year) did not cause "other operating expenses" (as defined below) (on an annualized basis and net of any expense support payments received by the Company during such fiscal year) to exceed the lesser of (A) 1.75% of the Company's average net assets attributable to Shares for the fiscal year-to-date period after taking such payments into account and (B) the percentage of the Company's average net assets attributable to Shares represented by "other operating expenses" during the fiscal year in which such expense support payment from FS Investments was made (provided, however, that this clause (B) did not apply to any reimbursement payment which related to an expense support payment from FS Investments made during the same fiscal year) and (ii) the Company would not reimburse FS Investments for expense support payments made by FS Investments for any calendar quarter if the annualized rate of regular cash distributions declared by the Company at the time of such reimbursement payment was less than the annualized rate of regular cash distributions declared by the Company at the time FS Investments made the expense support payment to which such reimbursement payment relates. The Company was not obligated to pay interest on the reimbursements it was required to make to FS Investments under the expense reimbursement agreement. "Other operating expenses" meant the Company's total "operating expenses" (defined below), excluding base management fees, incentive fees, offering and organization expenses, financing fees and costs, interest expense, brokerage commissions and extraordinary expenses. "Operating expenses" meant all operating costs and expenses incurred, as determined in accordance with U.S. generally accepted accounting principles for investment companies.

        During the year ended December 31, 2017, the Company accrued $31,260 for expense reimbursements that FS Investments has agreed to pay, including $5,945 in expense reimbursements accrued for the three months ended December 31, 2017. As discussed in the footnotes to the table above, the Company offset $14,816 in management fees payable and $10,499 in subordinated income

incentive fees payable by the Company to FS Investment Advisor during the year ended December 31, 2017. As of December 31, 2017, the Company had $5,945 of reimbursements due from FS Investments, which the Company expects to offset against management fees payable by the Company to FS Investment Advisor. As of December 31, 2016, there were no reimbursements payable to the Company from FS Investments.

        As discussed above, under the expense reimbursement agreement, amounts reimbursed to the Company by FS Investments may become subject to repayment by the Company in the future. During the year ended December 31, 2017, the Company paid $2,858 in expense recoupments to FS Investments. As of December 31, 2017, $28,104 of reimbursements may become subject to repayment by the Company to FS Investments in the future.

        The following table reflects the expense reimbursement payments due from FS Investments to the Company as of December 31, 2017 that may become subject to repayment by the Company to FS Investments:

        FS Investments terminated the expense reimbursement agreement upon entry into the FS/EIG investment advisory and administrative services agreement. As of the termination date, there were no reimbursements payable to the Company from FS Investments and the Company did not have any expense recoupments due to FS Investments.

        FS Investments is controlled by the Company's chairman and chief executive officer, Michael C. Forman, and its vice-chairman, David J. Adelman.

FS Benefit Trust

        FS Benefit Trust, or FS Trust, was formed as a Delaware statutory trust for the purpose of awarding equity incentive compensation to employees of FS Investments and its affiliates. During the years ended December 31, 2017 and 2016, FS Trust purchased $216 and $203, respectively, of the Company's Shares at a purchase price per share of $8.64, and $8.10, respectively, which price is equal to the institutional offering price in effect on the date of purchase.

Exemptive Relief

        As a BDC, the Company is subject to certain regulatory restrictions in making its investments. For example, BDCs generally are not permitted to co-invest with certain affiliated entities in transactions originated by the BDC or its affiliates in the absence of an exemptive order from the SEC. However, BDCs are permitted to, and may, simultaneously co-invest in transactions where price is the only negotiated term. In an order dated April 10, 2018, the SEC granted exemptive relief permitting the Company, subject to the satisfaction of certain conditions, to co-invest in certain privately negotiated

14

Table of Contents

investment transactions with certain funds and accounts managed by EIG Global Energy Partners or its affiliates, or the Company's co-investment affiliates. The Company believes this relief will enhance its ability to further its investment objectives and strategy. The Company believes this relief may also increase favorable investment opportunities for it, in part, by allowing it to participate in larger investments, together with the Company's co-investment affiliates, than would be available to the Company if such relief had not been obtained. The Company had previously relied on an order dated June 4, 2013, pursuant to which the SEC granted exemptive relief permitting the Company, subject to the satisfaction of certain conditions, to co-invest in certain privately negotiated investment transactions with certain of the Company's affiliates.

Potential Conflicts of Interest

        The members of the senior management and investment teams of the Advisor serve or may serve as officers, directors or principals of entities that operate in the same or a related line of business as the Company does, or of investment vehicles managed by the same personnel, including in similar or other capacities for the investment advisers to future investment vehicles affiliated with FS Investments or EIG Global Energy Partners. In serving in these multiple and other capacities, they may have obligations to other clients or investors in those entities, the fulfillment of which may not be in the Company's best interests or in the best interest of the Company's shareholders. The Company's investment objectives may overlap with the investment objectives of such investment funds, accounts or other investment vehicles. For example, the Company relies on the Advisor to manage its day-to-day activities and to implement its investment strategy. The Advisor, FS Investments, EIG Global Energy Partners and certain of certain of their affiliates are presently, and plan in the future to continue to be, involved with activities which are unrelated to the Company. As a result of these activities, the Advisor, FS Investments, EIG Global Energy Partners, their employees and certain of their affiliates will have conflicts of interest in allocating their time between the Company and other activities in which they are or may become involved, including the management of other investment vehicles.

        The Advisor's affiliates and its personnel are simultaneously providing investment advisory services to other affiliated entities. The Advisor may determine that it is appropriate for the Company and one or more other investment accounts managed by the Advisor's affiliates to participate in an investment opportunity. To the extent the Company is able to make co-investments with investment accounts managed by the Advisor or its affiliates, these co-investment opportunities may give rise to conflicts of interest or perceived conflicts of interest among the Company and the other participating accounts. In addition, conflicts of interest or perceived conflicts of interest may also arise in determining which investment opportunities should be presented to the Company and other participating accounts. To mitigate these conflicts, the Advisor will seek to execute such transactions on a fair and equitable basis and in accordance with its allocation policies, taking into account various factors, which may include: the source of origination of the investment opportunity; investment objectives and strategies; tax considerations; risk, diversification or investment concentration parameters; characteristics of the security; size of available investment; available liquidity and liquidity requirements; regulatory restrictions; and/or such other factors as may be relevant to a particular transaction. As affiliates of FS Investments and EIG Global Energy Partners currently serve as the investment adviser to other entities and accounts, it is possible that some investment opportunities will be provided to such other entities and accounts rather than to the Company.

Trustee Independence

        A majority of the members of the Board are not "interested persons," as defined in Section 2(a)(19) of the 1940 Act, of the Company or the Advisor, and are "independent" as defined in Rule 5605(a)(2) of The NASDAQ Stock Market LLC. Section 2(a)(19) of the 1940 Act defines an "interested person" to include, among other things, any person who has, or within the last two years had, a material business or professional relationship with the Company.

        The Board is currently comprised of eight trustees, six of whom are Independent Trustees. The Board has determined that the following trustees are Independent Trustees: Messrs. Brown, Chandler, Goldstein, Pizzi, Vague and Williams. Based upon information requested from each trustee concerning his background, employment and affiliations, the Board has affirmatively determined that none of the Independent Trustee nominees has, or within the last two years had, a material business or professional

        Set forth in the table below are audit fees, audit-related fees, tax fees and all other fees billed to the Company by RSM US LLP for professional services performed for the Company's fiscal years ended December 31, 2017 and 2016:

Pre-Approval Policies and Procedures

        The Company's Audit Committee reviews, negotiates and approves in advance the scope of work, any related engagement letter and the fees to be charged by the Company's independent registered public accounting firm for audit services and permitted non-audit services for the Company and for permitted non-audit services for the Advisor and any affiliates thereof that provide services to the Company if such non-audit services have a direct impact on the operations or financial reporting of the Company. Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the Audit Committee for specific pre-approval in accordance with its pre-approval policy, irrespective of the amount of fees associated with such services, and cannot commence until such approval has been granted. Normally, pre-approval is considered at regularly scheduled meetings of the Audit Committee. However, the Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee does not delegate its responsibilities to pre-approve services performed by RSM US LLP to management. All of the audit and permitted non-audit services described above for which RSM US LLP billed the Company for the fiscal years ended December 31, 2017 and 2016 were pre-approved by the Audit Committee.
