BOOZ ALLEN HAMILTON HOLDING CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables in thousands, except share and per share data or unless otherwise noted)

1. BUSINESS OVERVIEW

Organization

Booz Allen Hamilton Holding Corporation, including its wholly owned subsidiaries, or the Company, we, us, and our, was incorporated in Delaware in May 2008. The Company provides management and technology consulting, engineering, analytics, digital solutions, mission operations, and cyber expertise to U.S. and international governments, major corporations, and not-for-profit organizations. The Company reports operating results and financial data in one reportable segment. The Company is headquartered in McLean, Virginia, with approximately 25,300 employees as of September 30, 2018.

2. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission, or SEC, and should be read in conjunction with the information contained in the Company's Annual Report on Form 10-K for the year ended March 31, 2018. The interim period unaudited condensed consolidated financial statements are presented as described below. Certain information and disclosures normally required for annual financial statements have been condensed or omitted pursuant to GAAP and SEC rules and regulations. In the opinion of management, all adjustments considered necessary for fair presentation of the results of the interim period presented have been included. The Company’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The results of operations for the six months ended September 30, 2018 are not necessarily indicative of results to be expected for the full fiscal year.

The condensed consolidated financial statements and notes of the Company include its subsidiaries, and the joint ventures and partnerships over which the Company has a controlling financial interest. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies.

Effective April 1, 2018, the Company adopted Accounting Standards Codification (ASC) No. 606, Revenue from Contracts with Customers (Topic 606), and Accounting Standard Updates (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, on a full retrospective method for all amounts and percentages presented and disclosures set forth in this Form 10-Q.

Certain amounts reported in the Company's prior year condensed consolidated financial statements have been reclassified to conform to the current year presentation.

Accounting Estimates

The preparation of financial statements in conformity with GAAP requires 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 revenue and expenses during the reporting periods. Areas of the financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, certain deferred costs, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.

Recently Adopted Accounting Standards

The Company has accounted for the tax effects of the Tax Cuts and Jobs Act, or the 2017 Tax Act, under the guidance of Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, or SAB 118, on a provisional basis as of the fourth quarter of fiscal 2018. During the three months ended September 30, 2018, the Company continued its assessment of the 2017 Tax Act, including the potential accounting impact for any new guidance issued during the quarter. The Company made immaterial provisional adjustments associated with the limitation on the deductibility of certain executive compensation based on its preliminary assessment of the recently issued IRS Notice 2018-68. There were no additional changes to the provisional amounts recorded at March 31, 2018. The Company expects to complete its accounting assessment within the prescribed measurement period. See Note 10 to our consolidated financial statements for further information regarding the updated effects of the 2017 Tax Act during the second quarter of fiscal 2019.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Codification No. 606, Revenue from Contracts with Customers (Topic 606). Topic 606, as amended, replaced existing revenue recognition standards by outlining a single set of comprehensive principles for recognizing revenue. The revenue standard also significantly expanded the disclosure requirements for revenue arrangements. Amendments to Topic 606 have generally focused on promoting a more consistent interpretation and application of the principles for recognizing revenue.

Topic 606 was effective for the Company beginning on April 1, 2018 (i.e., beginning with the first quarter fiscal 2019 interim financial statements). The Company adopted the new revenue standard using the full retrospective transition method, which requires that it be applied to each prior reporting period presented and that the cumulative effect of applying the standard be recognized at the earliest period presented (i.e., April 1, 2016, the beginning of the first quarter of fiscal 2017). During fiscal 2018, the Company completed its assessment of the cumulative effect of adopting Topic 606 and assessed the impact to be immaterial as of the date of adoption. The cumulative impact on our retained earnings for the earliest period presented of April 1, 2016 was an increase of $2.9 million. Thereafter, the adoption of Topic 606 increased our fiscal 2017 retained earnings by $8.4 million and decreased our fiscal 2018 retained earnings by $3.4 million, resulting in a cumulative impact on our retained earnings of $7.9 million as of April 1, 2018. The impact of Topic 606 on fiscal 2017 and 2018 results may not be representative of the impact on subsequent years’ results.

For more information on the notable impacts of the adoption of Topic 606 on the Company's accounting policies, practices, estimates, and significant judgments, refer to the Company's Annual Report on Form 10-K for the year ended March 31, 2018 and Note 3, Revenue Recognition.

The Company also retrospectively adopted ASU 2017-07, which changed the presentation of net periodic benefit cost components on the condensed consolidated statement of operations. Under this guidance, the service cost component of net periodic benefit cost continues to be presented consistent with other employee compensation costs and within operating income, while the remaining components of net periodic benefit costs are excluded from operating income. As a result, $1.9 million and $3.8 million of net periodic benefit costs related to non-service components, for the three and six months ended September 30, 2017 respectively, were reclassified to Other income (expense), net in the condensed consolidated statement of operations in the second quarter of fiscal 2018.

The Company's previously issued condensed consolidated financial statements have been adjusted for the retrospective adoption of both Topic 606 and ASU 2017-07, as summarized in the following table:

	Three Months Ended September 30, 2017								Six Months Ended September 30, 2017

Recent Accounting Pronouncements Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance requires a customer in a cloud computing arrangement that is a service contract to follow existing internal-use software guidance to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with that of implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 is effective for interim reporting periods for fiscal years beginning after December 15, 2019. Early adoption is permitted. The standard may be adopted either retrospectively or prospectively. The Company is currently assessing the future impact of this update on its consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for

6

qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, the guidance also expands an entity's ability to apply hedge accounting for nonfinancial and financial risk components, simplifies the hedge documentation and hedge effectiveness assessment requirements, and modifies certain disclosure requirements. ASU 2017-12 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability of accounting for lease transactions. The new leasing standard requires lessees to recognize lease assets and lease liabilities on their balance sheet for all leases with a lease term of greater than 12 months. Lessor accounting is largely unchanged. Topic 842 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB provided an alternative transition method of adoption through ASU No. 2018-11, Targeted Improvements, which permits the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company intends to adopt the standard beginning in fiscal 2020 using the modified retrospective transition approach, specifically, using the alternative transition method provided by ASU 2018-11.

A dedicated implementation team has been established that continues to make progress toward completing the evaluation of the impact of the new standard. The Company's assessment efforts to date have included reviewing the provisions of Topic 842, gathering information to evaluate its lease population and portfolio, evaluating the nature of real and personal property and other arrangements that may meet the definition of a lease, designing and implementing one-time implementation controls as well as new post-adoption lease processes and controls, implementing a new lease accounting software solution, and evaluating certain accounting policy elections. The Company anticipates finalizing its accounting policy, accounting software, systems and process modifications during the fourth quarter of fiscal 2019.

Based on a preliminary assessment, the Company does not expect there to be a significant change in determining what constitutes a lease, however, the Company expects that virtually all of its operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in a significant increase in the assets and liabilities on its consolidated balance sheets. The pattern of recognition for operating leases within the consolidated statements of operations and comprehensive income is not anticipated to significantly change. The adoption is not expected to impact the Company’s ability to comply with financial covenants as defined within the Company's Sixth Amendment to its Credit Agreement dated July 23, 2018, as discussed further in Note 8, Debt. The Company is continuing to refine its process for quantifying the financial statement impacts and anticipates finalizing its assessment of the materiality of adopting Topic 842 in conjunction with reporting its results for the third quarter of fiscal 2019.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The amendments set forth certain presentation requirements, including that such analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed with all significant reconciling items described by appropriate captions with contributions from and distributions to owners shown separately. This final rule is effective 30 days after publication in the Federal Register and will generally be effective for the Company for the third quarter of fiscal year 2019. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

Other accounting and reporting pronouncements issued after September 30, 2018 and through the filing date are not expected to have a material impact on the Company's condensed consolidated financial statements.

3. REVENUE

Revenue Recognition

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies and, to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-materials contracts, and fixed-price contracts.

The Company considers a contract with a customer to exist under Topic 606 when there is approval and commitment from both the Company and the customer, the rights of the parties and payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. The Company also will consider whether two or more contracts entered into with the same customer should be combined and accounted for as a single contract. Furthermore, in

7

certain transactions with commercial clients and with the U.S. government, the Company may commence providing services prior to receiving a formal approval from the customer. In these situations, the Company will consider the factors noted above, the risks associated with commencing the work and legal enforceability in determining whether a contract with the customer exists under Topic 606.

Customer contracts are often modified to change the scope, price, specifications or other terms within the existing arrangement. Contract modifications are evaluated by management to determine whether the modification should be accounted for as part of the original performance obligation(s) or as a separate contract. If the modification adds distinct goods or services and increases the contract value proportionate to the stand-alone selling price of the additional goods or services, it will be accounted for as a separate contract. Generally, the Company’s contract modifications do not include goods or services which are distinct, and therefore are accounted for as part of the original performance obligation(s) with any impact on transaction price or estimated costs at completion being recorded as through a cumulative catch-up adjustment to revenue.

The Company evaluates each service deliverable contracted with the customer to determine whether they represent promises to transfer distinct goods or services. Under Topic 606, these are referred to as performance obligations. One or more service deliverables often represent a single performance obligation. This evaluation requires significant judgment and the impact of combining or separating performance obligations may change the time over which revenue from the contract is recognized. The Company’s contracts generally provide a set of integrated or highly interrelated tasks or services and are therefore accounted for as a single performance obligation. However, in cases where we provide more than one distinct good or service within a customer contract, the contract is separated into individual performance obligations which are accounted for discretely.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and are priced based on estimated or actual costs of providing the goods or services. The Company derives a majority of its revenue from contracts awarded through a competitive bidding process. Pricing for non-U.S. government agencies and commercial customers is based on discrete negotiations with each customer. Certain of the Company’s contracts contain award fees, incentive fees or other provisions that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. Management estimates variable consideration as the most likely amount that we expect to achieve based on our assessment of the variable fee provisions within the contract, prior experience with similar contracts or clients, and management’s evaluation of the performance on such contracts. The Company may perform work under a contract that has not been fully funded if the work has been authorized by the management and the customer to proceed. The Company evaluates unfunded amounts as variable consideration in estimating the transaction price. We include the estimated variable consideration in our transaction price to the extent that it is probable that a significant reversal of revenue will not occur upon the ultimate settlement of the variable fee provision. In the limited number of situations where our contracts with customers contain more than one performance obligation, the Company allocates the transaction price of a contract between the performance obligations in the proportion to their respective stand-alone selling prices. The Company generally estimates the stand-alone selling price of performance obligations based on an expected cost-plus margin approach as allowed under Topic 606. Our U.S. government contracts generally contain FAR provisions that enable the customer to terminate a contract for default or for the convenience of the U.S. government.

The Company recognizes revenue for each performance obligation identified within our customer contracts when, or as, the performance obligation is satisfied by transferring the promised goods or services. Revenue may either be recognized over time, or at a point in time. The Company generally recognizes revenue over time as our contracts typically involve a continuous transfer of control to the customer. A continuous transfer of control under contracts with the U.S. government and its agencies is evidenced by clauses which require the Company to be paid for costs incurred plus a reasonable margin in the event that the customer unilaterally terminates the contract for convenience. For contracts where the Company recognizes revenue over time, a contract cost-based input method is generally used to measure progress towards satisfaction of the underlying performance obligation(s). Contract costs include direct costs such as materials, labor and subcontract costs, as well as indirect costs identifiable with, or allocable to, a specific contract that are expensed as incurred. The Company does not incur material incremental costs to acquire or fulfill contracts. Under a contract cost-based input method, revenue is recognized based on the proportion of contract costs incurred to the total estimated costs expected to be incurred upon completion of the underlying performance obligation. The Company includes both funded and unfunded portions of customer contracts in this estimation process.

For interim financial reporting periods, contract revenue attributable to indirect costs is recognized based upon agreed-upon annual forward-pricing rates established with the U.S. government at the start of each fiscal year. Forward pricing rates are estimated and agreed upon between the Company and the U.S. government and represent indirect contract costs required to execute and administer contract obligations. The impact of any agreed-upon changes, or changes in the estimated annual forward-pricing rates, will be recorded in the interim financial reporting period when such changes are identified. This change relates to the interim financial reporting period differences between the actual indirect cost incurred and allocated to customer

contracts compared to the estimated amounts allocated to contracts using the estimated annual forward-pricing rates established with the U.S. government.

On certain contracts, principally time-and-materials and cost-reimbursable-plus-fee contracts, revenue is recognized using the right-to-invoice practical expedient as the Company is contractually able to invoice the customer based on the control transferred. However, we did not elect to use the practical expedient which would allow the Company to exclude contracts recognized using the right-to-invoice practical expedient from the remaining performance obligations disclosed below. Additionally, for stand-ready performance obligations to provide services under fixed-price contracts, revenue is recognized over time using a straight-line measure of progress as the control of the services is provided to the customer ratably over the term of the contract. If a contract does not meet the criteria for recognition of revenue over time, we recognize revenue at the point in time when control of the good or service is transferred to the customer. Determining a measure of progress towards the satisfaction of performance obligations requires management to make judgments that may affect the timing of revenue recognition.

In addition to the right-to-invoice practical expedient discussed above, the Company applied certain other practical expedients permitted by Topic 606, which include: a) using the portfolio approach where contracts with similar characteristics were assessed collectively to evaluate risk of being impacted by the adoption of Topic 606; b) applying the practical expedient allowing the Company to not restate completed contracts which began and ended in the same fiscal year prior to the date of the initial adoption; and c) electing to omit the disclosure related to remaining performance obligations for reporting periods presented before the date of the initial adoption.

Contract Estimates

Many of our contracts recognize revenue under a contract cost-based input method and require an Estimate-at-Completion (EAC) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at completion of performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For the three and six months periods ended September 30, 2018 and 2017, respectively, the aggregate impact of adjustments in contract estimates was not material.

Performance Obligations

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options.

As of September 30, 2018, the Company had $7.8 billion of remaining performance obligations and we expect to recognize more than half of the remaining performance obligations as revenue over the next 12 months, and approximately three quarters over the next 24 months. The remainder is expected to be recognized thereafter.

Disaggregation of Revenue

We disaggregate our revenue from contracts with customers by contract type, customer, as well as whether the Company acts as prime contractor or sub-contractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following series of tables presents our revenue disaggregated by these categories.

Revenue by Contract Type:

We generate revenue under the following three basic types of contracts:

• Cost-Reimbursable Contracts: Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee.

• Time-and-Materials Contracts: Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates.

9

• Fixed-Price Contracts: Under a fixed-price contract, we agree to perform the specified work for a predetermined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss.

The table below presents the total revenue for each type of contract:

	Three Months Ended September 30,								Six Months Ended September 30,
	2018				2017				2018				2017
Cost-reimbursable	$	851,394	53	%	$	795,819	52	%	$	1,711,278	53	%	$	1,565,914	51	%

Revenue by Whether the Company Acts as a Prime Contractor or a Sub-Contractor:

	Three Months Ended September 30,								Six Months Ended September 30,
	2018				2017				2018				2017
Prime Contractor	$	1,482,153	92	%	$	1,413,210	92	%	$	2,989,335	92	%	$	2,801,249	91	%

Contract Balances

Contract assets primarily consist of unbilled receivables typically resulting from revenue recognized exceeding the amount billed to the customer and right to payment is not just subject to the passage of time. Contract liabilities primarily consist of advance payments, billings in excess of costs incurred and deferred revenue. Contract assets and liabilities are reported on a net contract basis at the end of each reporting period. The Company maintains an allowance for doubtful accounts to provide for an estimate of uncollected receivables. Refer to Note 5 for more information on receivables recognized from contracts accounted for under Topic 606.

The following table summarizes the contract balances recognized on the Company’s condensed consolidated balance sheets:

	September 30, 2018		March 31, 2018
Contract assets:
Current	$	749,672	$	738,646
Long-term	60,093		59,633
Total	$	809,765	$	798,279
Contract liabilities:
Advance payments, billings in excess of costs incurred and deferred revenue	$	22,165	$	27,522

10

Changes in contract assets and contract liabilities are primarily due to the timing difference between the Company’s performance of services and payments from customers. For the three months ended September 30, 2018 and 2017, we recognized revenue of $3.8 million and $0.8 million and for the six months ended September 30, 2018 and 2017, we recognized revenue of $10.6 million and $6.6 million related to our contract liabilities on April 1, 2018 and 2017, respectively. To determine revenue recognized from contract liabilities during the reporting periods, the Company allocates revenue to individual contract liability balances and applies revenue recognized during the reporting periods first to the beginning balances of contract liabilities until the revenue exceeds the balances.

4. EARNINGS PER SHARE

The Company computes basic and diluted earnings per share amounts based on net income for the periods presented. The Company uses the weighted-average number of common shares outstanding during the period to calculate basic earnings per share, or EPS. Diluted EPS adjusts the weighted average number of shares outstanding to include the dilutive effect of outstanding common stock options and other stock-based awards.

The Company currently has outstanding shares of Class A Common Stock. Unvested Class A Restricted Common Stock holders are entitled to participate in non-forfeitable dividends or other distributions. These unvested restricted shares participated in the Company's dividends declared and were paid in the first and second quarters of fiscal 2019 and 2018. As such, EPS is calculated using the two-class method whereby earnings are reduced by distributed earnings as well as any available undistributed earnings allocable to holders of unvested restricted shares. A reconciliation of the income used to compute basic and diluted EPS for the periods presented are as follows:

	Three Months Ended September 30,				Six Months Ended September 30,
	2018		2017		2018		2017
Earnings for basic computations (1)	$	92,127	$	72,966	$	195,681	$	142,974
Weighted-average common shares outstanding for basic computations	142,443,058		147,085,314		142,861,491		147,400,153
Earnings for diluted computations (1)	$	92,130	$	72,971	$	195,690	$	142,986
Dilutive stock options and restricted stock	1,265,851		1,802,183		1,353,582		1,976,722
Weighted-average common shares outstanding for diluted computations	143,708,909		148,887,497		144,215,073		149,376,875
Earnings per common share
Basic	$	0.65	$	0.50	$	1.37	$	0.97
Diluted	$	0.64	$	0.49	$	1.36	$	0.96

(1) During the three months ended September 30, 2018 and 2017, approximately 0.9 million and 1.4 million participating securities, respectively, were paid dividends totaling $0.2 million in both periods. During the six months ended September 30, 2018 and 2017, approximately 0.9 million and 1.4 million participating securities, respectively, were paid dividends totaling $0.3 million and $0.4 million, respectively. For the three months ended September 30, 2018 and 2017, there were undistributed earnings of $0.4 million and $0.4 million, respectively, allocated to the participating class of securities in both basic and diluted EPS. For the six months ended September 30, 2018 and 2017, there were undistributed earnings of $0.9 million and $0.9 million, respectively, allocated to the participating class of securities in both basic and diluted EPS. The allocated undistributed earnings and the dividends paid comprise the difference between net income presented on the condensed consolidated statements of operations and earnings for basic and diluted computations for the three and six months ended September 30, 2018 and 2017.

The EPS calculation for the three months ended September 30, 2018 and 2017 excludes 0.2 million and 0.4 million options, respectively, as their impact was anti-dilutive. The EPS calculation for the six months ended September 30, 2018 and 2017 excludes 0.2 million and 0.3 million options, respectively, as their impact was anti-dilutive.

5. ACCOUNTS RECEIVABLE, NET OF ALLOWANCE

Accounts receivable, net of allowance consisted of the following:

	September 30, 2018			March 31, 2018
Current assets
Accounts receivable–billed	$	416,909		$	395,136
Accounts receivable–unbilled	749,672			738,646
Allowance for doubtful accounts	(1,255		)	(77		)
Accounts receivable, net of allowance	1,165,326			1,133,705
Other long-term assets
Accounts receivable–unbilled	60,093			59,633
Total accounts receivable, net	$	1,225,419		$	1,193,338

Unbilled amounts represent revenues for which billings have not been presented to customers at quarter-end or year-end. These amounts are usually billed and collected within one year. Long-term unbilled receivables not anticipated to be billed and collected within one year, which are primarily related to retainage, holdbacks, and long-term rate settlements to be billed at contract closeout, are included in other long-term assets in the accompanying condensed consolidated balance sheets. The Company recognized a provision for doubtful accounts (including certain unbilled reserves) of $10.6 million and $2.2 million for the three months ended September 30, 2018 and 2017, respectively and $10.7 million and $3.1 million for the six months ended September 30, 2018 and 2017.

The primary financial instruments, other than derivatives, that potentially subject the Company to concentrations of credit risk are accounts receivable. The Company's primary customers are U.S. federal government agencies and prime contractors under contracts with the U.S. government. The Company continuously reviews its accounts receivable and records provisions for doubtful accounts as needed.

6. ACCOUNTS PAYABLE AND OTHER ACCRUED EXPENSES

Accounts payable and other accrued expenses consisted of the following:

	September 30, 2018		March 31, 2018

Term Loans and Revolving Credit Facility

On July 23, 2018 (the "Amendment Effective Date"), Booz Allen Hamilton Inc. ("Booz Allen Hamilton") and Booz Allen Hamilton Investor Corporation ("Investor"), and certain wholly-owned subsidiaries of Booz Allen Hamilton, entered into the Sixth Amendment (the "Sixth Amendment") to the Credit Agreement (as amended, the "Credit Agreement"), dated as of July 31, 2012 among Booz Allen Hamilton, Investor, certain wholly-owned subsidiaries of Booz Allen Hamilton and Bank of America, N.A., as Administrative Agent, and Collateral Agent and the other lenders and financial institutions from time to time party thereto (as previously amended by the First Amendment to the Credit Agreement, dated as of August 16, 2013, the Second Amendment to Credit Agreement, dated as of May 7, 2014, the Third Amendment to the Credit Agreement, dated as of July 13, 2016, the Fourth Amendment to the Credit Agreement, dated as of February 6, 2017, and the Fifth Amendment to the Credit Agreement, dated as of March 7, 2018). The Sixth Amendment provides for a new delayed draw (the "Delayed Draw Facility") on the tranche A term loan ("Term Loan A") facility in the amount of up to $400.0 million and extended the maturity of the Term Loan A and the revolving credit facility (the "Revolving Credit Facility") to July 2023. Additionally, the Sixth Amendment reduced the interest rate spread applicable to the Term Loan A and the Revolving Credit Facility from a range of 1.50% to 2.25% to a range of 1.25% to 2.00% based on consolidated net total leverage. The interest rate applicable to the Term Loan B ("Term Loan B" and, together with Term Loan A, the "Term Loans") remained unchanged.

Prior to the Sixth Amendment, approximately $1,079.5 million was outstanding under Term Loan A. Pursuant to the Sixth Amendment, certain lenders converted their existing Term Loan A loans into a new tranche of Term Loan A loans in an aggregate amount, along with Term Loan A loans advanced by certain new lenders, of approximately $1,479.5 million, $400.0 million of which will be available as the Delayed Draw Facility. The Delayed Draw Facility is accessible for nine months from the Amendment Effective Date (the "Delayed Draw Availability Period"). The Company is able to draw on the Delayed Draw Facility on up to two occasions during the Delayed Draw Availability Period in an amount per draw (x) of not less than $100.0 million per draw or (y) equal to the amount of unused commitments in respect of the Delayed Draw Facility remaining at the time of such borrowing. The proceeds from the new lenders were used to prepay in full all of the existing Term Loan A that was not converted into the new Term Loan A tranche. The proceeds of the Delayed Draw Facility will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

Prior to the Sixth Amendment, $500.0 million was available under the revolving credit facility. Pursuant to the Sixth Amendment, certain lenders under the Existing Credit Agreement converted their Existing Revolving Commitments into a new tranche of revolving commitments (the "New Revolving Commitments" and the revolving credit loans made thereunder, the "New Revolving Loans") in an aggregate amount, along with New Revolving Commitments of certain new lenders, of $500.0 million.

As of September 30, 2018, the Credit Agreement provided Booz Allen Hamilton with a $1,064.7 million Term Loan A, $400.0 million Delayed Draw Facility, a $393.0 million Term Loan B, and $500.0 million in New Revolving Commitments with a sub-limit for letters of credit of $100.0 million. As of September 30, 2018, the maturity date of Term Loan A and the termination date for the Revolving Credit Facility was July 23, 2023 and the maturity date of Term Loan B was June 30, 2023. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Investor, and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. Subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the Term Loans or New

14

Revolving Credit Facility may be expanded (or a new term loan facility or revolving credit facility added to the existing facilities) by up to (i) greater of (x) $627 million and (y) 100% of consolidated EBITDA of Booz Allen Hamilton, as of the end of the most recently ended four quarter period for which financial statements have been delivered pursuant to the Credit Agreement plus (ii) the aggregate principal amount under which pro forma consolidated net secured leverage remains less than or equal to 3.50:1.00.

At Booz Allen Hamilton’s option, borrowings under the Secured Credit Facility bear interest based either on LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or a base rate (equal to the highest of (x) the administrative agent’s prime corporate rate, (y) the overnight federal funds rate plus 0.50%, and (z) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. The applicable margin for Term Loan B is 2.00% for LIBOR loans and 1.00% for base rate loans. Unused commitments under the Revolving Credit Facility are subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio.

Booz Allen Hamilton occasionally borrows under the Revolving Credit Facility in anticipation of cash demands. During the first and second quarters of fiscal 2019, Booz Allen Hamilton accessed a total of $70.0 million of the $500.0 million New Revolving Commitments. As of September 30, 2018 and March 31, 2018, there were no amounts outstanding under the Revolving Credit Facility.

The Credit Agreement requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity, and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include limitations on the following, in each case subject to certain exceptions: (i) indebtedness and liens, (ii) mergers, consolidations or amalgamations, liquidations, wind-ups or dissolutions, and disposition of all or substantially all assets; (iii) dispositions of property; (iv) restricted payments; (v) investments; (vi) transactions with affiliates; (vii) change in fiscal periods; (viii) negative pledges; (ix) restrictive agreements; (x) line of business; and (xi) speculative hedging. The events of default include the following, in each case subject to certain exceptions: (a) failure to make required payments under the Secured Credit Facility; (b) material breaches of representations or warranties under the Secured Credit Facility; (c) failure to observe covenants or agreements under the Secured Credit Facility; (d) failure to pay or default under certain other material indebtedness; (e) bankruptcy or insolvency; (f) certain Employee Retirement Income Security Act, or ERISA events; (g) certain material judgments; (h) actual or asserted invalidity of the Guarantee and Collateral Agreements or the other security documents or failure of the guarantees or perfected liens thereunder; and (i) a change of control. In addition, Booz Allen Hamilton is required to meet certain financial covenants at each quarter end, namely Consolidated Net Total Leverage and Consolidated Net Interest Coverage Ratios. As of September 30, 2018 and March 31, 2018, Booz Allen Hamilton was in compliance with all financial covenants associated with its debt and debt-like instruments.

Senior Notes

On April 25, 2017, Booz Allen Hamilton issued $350 million aggregate principal amount of its 5.125% Senior Notes (the "Senior Notes"), under an Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the "Subsidiary Guarantors"), and Wilmington Trust, National Association, as trustee (the "Trustee"), as supplemented by the First Supplemental Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, the Subsidiary Guarantors and the Trustee. Each of Booz Allen Hamilton's existing and future domestic restricted subsidiaries that guarantee its obligations under the Secured Credit Facility and certain other indebtedness will guarantee the Senior Notes on a senior unsecured basis. Interest is payable semi-annually on May 1 and November 1 of each year, beginning on November 1, 2017, and principal is due at maturity on May 1, 2025. In connection with the Senior Notes, the Company recognized $6.7 million of issuance costs, which were recorded as an offset against the carrying value of debt and will be amortized to interest expense over the term of the Senior Notes. During the first and second quarters of fiscal 2019, interest payments of $9.0 million were made for the Senior Notes.

Borrowings under the Term Loans and, if used, the Revolving Credit Facility, incur interest at a variable rate. In accordance with Booz Allen Hamilton’s risk management strategy, between April 6, 2017 and May 24, 2017, Booz Allen Hamilton executed a series of interest rate swaps. As of September 30, 2018, Booz Allen Hamilton had interest rate swaps with an aggregate notional amount of $450 million. These instruments hedge the variability of cash outflows for interest payments on the floating portion of the term loan debt. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (See Note 9 in our condensed consolidated financial statements).

DIC on the Revolving Credit Facility is recorded as a long-term asset on the condensed consolidated balance sheet and amortized ratably over the term of the Revolving Credit Facility.

9. DERIVATIVES

The Company utilizes derivative financial instruments to manage interest rate risk related to its variable rate debt. The Company’s objectives in using these interest rate derivatives, which were designated as cash flow hedges, are to manage its exposure to interest rate movements and reduce volatility to interest expense. During the first quarter of fiscal 2018, the Company entered into several forward starting floating-to-fixed interest rate swap agreements with multiple financial institutions with a start date of April 30, 2018. The aggregate notional amount of these interest rate swap agreements was $450 million as of September 30, 2018. The swaps have staggered maturities, ranging from June 30, 2021 to June 30, 2022. These swaps mature within the last tranche of the Company's floating rate debt (June 30, 2023).

The floating-to-fixed interest rate swaps involve the exchange of variable interest amounts from a counterparty for the Company making fixed-rate interest payments over the life of the agreements without exchange of the underlying notional amount and effectively converting a portion of the variable rate debt into fixed interest rate debt.

Derivative instruments are recorded in the condensed consolidated balance sheet on a gross basis at estimated fair value. As of September 30, 2018, $2.8 million and $9.1 million were classified as other current assets and other long-term assets, respectively, on the condensed consolidated balance sheet. As of March 31, 2018, $0.7 million and $7.2 million were classified as other current assets and other long-term assets, respectively, on the condensed consolidated balance sheet.

For interest rate swaps designated as cash flow hedges, the changes in the fair value of derivatives is recorded in Accumulated Other Comprehensive Income, or AOCI, net of taxes, and is subsequently reclassified into interest expense in the period that the hedged forecasted interest payments are made on the Company's variable-rate debt. For the three and six months ended September 30, 2018, a $1.2 million and $3.0 million gain, respectively, was recognized in AOCI, and $0.1 million and $0.08 million was reclassified into interest expense. For the three and six months ended September 30, 2017, a $0.1 million and $0.6 million loss was recognized in AOCI, and there were no amounts reclassified into interest expense. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. As of September 30, 2018, there was no ineffectiveness recognized in earnings.

Over the next 12 months, the Company estimates that $2.8 million will be reclassified as a decrease to interest expense. Cash flows associated with periodic settlements of interest rate swaps will be classified as operating activities in the condensed consolidated statement of cash flows.

The Company is subject to counterparty risk in connection with its interest rate swap derivative contracts. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The Company mitigates this credit risk by entering into agreements with credit-worthy counterparties and regularly reviews its credit exposure and the creditworthiness of the counterparties.

10. INCOME TAXES

The 2017 Tax Act was enacted on December 22, 2017. The 2017 Tax Act reduced the U.S. federal corporate tax rate from 35.0% to 21.0% effective January 1, 2018. At September 30, 2018, the Company's assessment for the following elements was not complete: (1) the acceleration of depreciation; and (2) the limitation on the deductibility of certain executive compensation. However, based on a preliminary assessment of the recently issued IRS Notice 2018-68, the Company recognized an additional measurement-period adjustment of $1.1 million relating to the deductibility of certain executive compensation, with a corresponding adjustment of $1.1 million to income tax expense during the quarter. The effect of the measurement-period adjustment on the three months ended September 30, 2018 effective tax rate was approximately 0.9%. The Company will continue to make and refine the calculations as additional analysis is completed and our estimates may be materially affected by additional clarifications and interpretations of the legislation. This includes the written consent the Company received from the IRS on October 19, 2018 in response to its application for a Change in Accounting Method filed on March 29, 2018. This method change is related to the Company’s recognition of revenue for income tax purposes associated with its unbilled receivables. Since this consent agreement was received subsequent to September 30, 2018, the financial statement effect related to a measurement-period adjustment of these changes will be recorded in the Company’s third quarter of fiscal 2019 pursuant to ASC 740. The Company will incorporate this method change in its fiscal 2018 federal and state income tax returns. As of September 30, 2018, the Company preliminarily estimates the measurement-period adjustment impact to fiscal 2019 from this method change to be approximately $28.9 million of a reduction to income tax expense.The Company expects to finalize its assessment of all provisional amounts within the allowed one-year measurement period provided for under SAB 118. Other than the executive compensation discussed above, the Company has not made any additional adjustments to fiscal 2018 provisional amounts during the six months ended September 30, 2018.

The Company’s effective income tax rates were 22.7% and 33.4% for the three months ended September 30, 2018 and 2017, respectively, and 23.5% and 33.6% for the six months ended September 30, 2018 and 2017, respectively. The decrease in the effective tax rate as compared to the same period last fiscal year was primarily due to the 2017 Tax Act's reduction of the U.S. federal corporate tax rate. The effective tax rates of 22.7% and 23.5% for the three and six months ended September 30, 2018 differ from the federal statutory rate of 21.0% primarily due to the inclusion of state income taxes and permanent rate differences, which are predominantly related to meals and entertainment and certain executive compensation, offset in the current three months by discrete tax items.

The Company is currently contesting tax assessments from the District of Columbia Office of Tax and Revenue for fiscal years 2013 through 2015 at various stages of applicable administrative and judicial processes, with a combined amount at issue of approximately $11.5 million, net of associated tax benefits as of September 30, 2018. The Company has taken similar tax positions with respect to subsequent fiscal years, totaling in aggregate $28.3 million. As of September 30, 2018, the Company does not maintain reserves for any uncertain tax positions related to the contested tax benefits, and, given the recoverable nature of the state tax expense, it does not believe the resolution of these matters will have a material adverse effect on its results of operations, cash flows or financial condition.

The Company continues to carry a reserve of $10.2 million for income tax uncertainties created with the business acquisition of eGov Holdings, Inc. (d/b/a Aquilent) in the fourth quarter of fiscal 2017 resulting from uncertainty in the sustainability of the acquiree's prior tax-return positions under examination with the relevant tax authorities.

11. OTHER LONG-TERM LIABILITIES

12. EMPLOYEE BENEFIT PLANS

Defined Contribution Plan

The Company sponsors the Employees’ Capital Accumulation Plan, or ECAP, which is a qualified defined contribution plan that covers eligible U.S. and international employees. ECAP provides for distributions, subject to certain vesting provisions, to participants by reason of retirement, death, disability, or termination of employment. Effective April 1, 2014, the Company transitioned from a discretionary employer contribution to an annual matching contribution of up to 6% of eligible annual income as determined by the Internal Revenue Code for the ECAP.  Total expense recognized under ECAP was $33.6 million and $30.7 million for the three months ended September 30, 2018 and 2017, respectively, and $66.2 million and $61.8 million for the six months ended September 30, 2018 and 2017, respectively. The Company-paid contributions were $16.9 million and $15.5 million for the three months ended September 30, 2018 and 2017, respectively, and $34.4 million and $31.1 million for the six months ended September 30, 2018 and 2017, respectively.

Defined Benefit Plan and Other Postretirement Benefit Plans

The Company provides postretirement healthcare benefits to former officers under a medical indemnity insurance plan, with premiums paid by the Company. This plan is referred to as the Officer Medical Plan. The Company also established a non-qualified defined benefit plan for all officers in May 1995, or the Retired Officers' Bonus Plan, which pays a lump-sum amount of $10,000 per year of service as an officer, provided the officer meets retirement vesting requirements. In addition, the Company provides a fixed annual allowance after retirement to cover financial counseling and other expenses. The Retired Officers' Bonus Plan is not salary related, but rather is based primarily on years of service. During fiscal 2017, the Company adopted a new plan which will provide for a one-time, lump sum retirement payment of one month’s salary when a vice-president retires from the Company, effective April 1, 2017. This is referred to as the Retired Vice-President Bonus Plan. Additionally, the Company offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability.

The components of net postretirement medical expense for the Officer Medical Plan were as follows:

	Three Months Ended September 30,				Six Months Ended September 30,
	2018		2017		2018		2017
Service cost	$	1,488	$	1,116	$	2,976	$	2,232
Interest cost	1,282		1,252		2,564		2,504
Net actuarial loss	527		568		1,054		1,135
Total postretirement medical expense	$	3,297	$	2,936	$	6,594	$	5,871

The service cost component of net periodic benefit cost is included in cost of revenue and general and administrative expenses, and the non-service cost components of net periodic benefit cost (interest cost and net actuarial loss) is included as part of other income (expense), net in the accompanying condensed consolidated statements of operations.

As of September 30, 2018 and March 31, 2018, the unfunded status of the post-retirement medical plan was $130.5 million and $126.9 million, respectively, which is included in other long-term liabilities in the accompanying condensed consolidated balance sheets.    

18

Deferred Compensation Plan

The Company established a non-qualified deferred compensation plan (the "Plan") for certain executives and other highly compensated employees that became effective in the current period. Pursuant to the Plan, participants are eligible to defer up to 100% of their incentive cash compensation on a tax deferred basis in excess of the IRS limits imposed on 401(k) plans. The assets of the plan are held in a consolidated trust and are subject to the claims of the Company's general creditors under federal and state laws in the event of insolvency. Consequently, the trust qualifies as a Rabbi trust for income tax purposes.

As of September 30, 2018, $3.2 million of plan investments and obligations were recorded in other long term assets and in other long term liabilities, respectively, in the condensed consolidated balance sheets, representing the fair value related to the deferred compensation plan. Adjustments to the fair value of the plan investments and obligations are recorded in operating expenses.

16. FAIR VALUE MEASUREMENTS

The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3).

A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The financial instruments measured at fair value in the accompanying condensed consolidated balance sheets consist of the following:

	Recurring Fair Value Measurements as of September 30, 2018
	Level 1		Level 2		Level 3		Total
Assets:
Current derivative instruments (1)	$	—	$	2,805	$	—	$	2,805
Long term derivative instruments (1)	—		9,128		—		9,128
Long term deferred compensation costs (2)	3,217		—		—		3,217
Total Assets	$	3,217	$	11,933	$	—	$	15,150
Liabilities:
Contingent consideration liability (3)	$	—	$	—	$	3,341	3,341
Long term deferred compensation costs (2)	3,217		—		—		3,217
Total Liabilities	$	3,217	$	—	$	3,341	$	6,558

	Recurring Fair Value Measurements as of March 31, 2018

(1) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 9 for further discussion on the Company’s derivative instruments designated as cash flow hedges.

(2)Investments in this category consist primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our condensed consolidated balance sheets.

(3) The Company recognized a contingent consideration liability of $3.6 million in connection with its acquisition of Aquilent in fiscal 2017. As of September 30, 2018 and March 31, 2018, the estimated fair value of the contingent consideration liability was $3.3 million and $3.6 million, respectively, and was valued using probability-weighted cash flows, which is based on the use of Level 3 fair value measurement inputs. The liability is recorded in other long-term liabilities in the condensed consolidated balance sheet.

The fair value of the Company's cash and cash equivalents, which are primarily Level 1 inputs, approximated its carrying values at September 30, 2018 and March 31, 2018. The fair value of the Company's debt instruments approximated its carrying value at September 30, 2018 and March 31, 2018. The fair value of debt is determined using quoted prices or other market information obtained from recent trading activity of each debt tranche in markets that are not active (Level 2 inputs). The fair value is corroborated by prices derived from the interest rate spreads of recently completed leveraged loan transactions of a similar credit profile, industry, and terms to that of the Company. The fair value of the Senior Notes is determined using quoted prices or other market information obtained from recent trading activity in the high-yield bond market (Level 2 inputs).

17. RELATED-PARTY TRANSACTIONS

In March 2017, the Company supported the formation of the Booz Allen Foundation, a nonprofit corporation organized and operated exclusively for charitable, scientific and educational purposes within the meaning of Section 501(c)(3) of the Code. The Company is the sole member of the foundation, which gives it the authority to appoint two of five of the Booz Allen Foundation's directors and consent rights regarding certain extraordinary corporate actions approved by the Company's Board of Directors. The Company has made a binding and irrevocable pledge of $5.0 million to the Booz Allen Foundation and recorded the pledge obligation in other current liabilities on the consolidated balance sheet of the Company in March 2017. As of September 30, 2018, $1.7 million of the pledge has been paid to the Booz Allen Foundation and is classified as operating activities in the condensed consolidated statement of cash flows.

18. COMMITMENTS AND CONTINGENCIES

Letters of Credit and Third-Party Guarantees

As of September 30, 2018 and March 31, 2018, the Company was contingently liable under open standby letters of credit and bank guarantees issued by our banks in favor of third parties that totaled $9.3 million and $6.3 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At September 30, 2018 and March 31, 2018, approximately $1.0 million and $1.4 million, respectively, of these instruments reduced the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $15.0 million facility established in fiscal 2015 of which $6.7 million and $10.1 million were available to the Company at September 30, 2018 and March 31, 2018, respectively.

Government Contracting Matters

For the three months ended September 30, 2018 and 2017, approximately 96% and 97% of the Company's revenue and for both the six months ended September 30, 2018 and 2017, approximately 97% of the Company's revenue was generated from contracts where the end user was an agency or department of the U.S. government, including contracts where the Company performed either as a prime contractor or subcontractor, and regardless of the geographic location in which the work was performed. U.S. government contracts and subcontracts are subject to extensive legal and regulatory requirements. From time to time and in the ordinary course of business, agencies of the U.S. government audit our contract costs and conduct inquiries and investigations of our business practices with respect to government contracts to determine whether the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government agencies, including the Defense Contract Audit Agency, routinely audit our contract costs, including allocated indirect costs for compliance with the Cost Accounting Standards and the Federal Acquisition Regulation. These agencies also conduct reviews and investigations and make inquiries regarding our accounting and other systems in connection with our performance and business practices with respect to our government contracts and subcontracts. U.S. government audits, inquiries, or investigations of the Company, whether related to the Company's U.S. government contracts or subcontracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including withholding of payments, suspension of payments, repayments, fines, or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting. Management believes it has recorded the appropriate provision for any audit, inquiry, or investigation of which it is aware. Management believes it has recorded the appropriate provision for the estimated losses that may be experienced from any such reductions and/or penalties. As of September 30, 2018 and March 31, 2018, the Company had recorded liabilities of approximately $179.9 million and $168.6 million, respectively, for its current best estimate of amounts to be refunded to customers for potential adjustments from audits or reviews of contract costs incurred subsequent to fiscal year 2011, and for contracts not yet closed that are impacted by settlement of audits or reviews of contract costs incurred in prior fiscal years.

Litigation

The Company is involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, management does not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on the Company’s financial condition and results of operations. As of September 30, 2018 and March 31, 2018, there were no material amounts accrued in the condensed consolidated financial statements related to these proceedings.

Six former officers and stockholders who had departed the Company prior to the acquisition of the Company by the Carlyle Group (the "Carlyle Acquisition") have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009, against us and certain of our current and former directors and officers. Three of these suits were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010. Another two of the original nine suits were consolidated into one complaint on September 24, 2014. Each of the suits arises out of the Carlyle Acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Some of the suits also allege that the acquisition price paid to stockholders was insufficient. The various suits assert claims for breach of contract, tortious interference with contract, breach of fiduciary duty, civil Racketeer Influenced and Corrupt Organizations Act, or RICO, violations, violations of the ERISA, and/or securities and common law fraud. Three of these suits have been dismissed with all appeals exhausted. The two suits that were consolidated into one action on September 24, 2014 were settled on April 16, 2015. One of the remaining suits has been dismissed by the United States District Court for the Southern District of California and such dismissal was upheld by the United States Court of Appeals for the Ninth Circuit. The plaintiff in this suit subsequently filed a Petition for Writ of Certiorari to the United States Supreme Court, which was denied by the United States Supreme Court on January 9, 2017. The other three remaining suits that were previously consolidated on September 7, 2010 have been dismissed by the United States District Court for the Southern District of New York and were on appeal before the United States Court of Appeals for the Second Circuit. On July 13, 2017, the United States Court of Appeals for the Second Circuit affirmed the ruling of the United States District Court for the Southern District of New York, except for one plaintiff’s securities fraud claim, which was remanded to the United States District Court for the Southern District of New York to give the plaintiff, Paul Kocourek, leave to file another amended complaint to attempt to plead a securities fraud claim. On April 6, 2018, the plaintiff filed an amended complaint in which Mr. Kocourek, individually, as Trustee of the Paul Kocourek Trust and on behalf of a putative class, alleges that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint. A lead plaintiff has not been appointed. On August 2, 2018, the defendants filed a motion to dismiss the amended complaint. On September 17, 2018, the plaintiff filed an opposition to the defendants’ motion to dismiss the amended complaint. The defendants filed their reply to plaintiff's opposition on October 17, 2018.

As of September 30, 2018, the aggregate alleged damages that will be sought in the remaining suit is unknown. As of September 30, 2018, although the outcome of any of these cases is inherently uncertain and may be materially adverse, based on current information, management does not expect them to have a material adverse effect on our financial condition and results of operations.

On June 7, 2017, Booz Allen Hamilton was informed that the U.S. Department of Justice (DOJ) is conducting a civil and criminal investigation of the Company. In connection with the investigation, the DOJ has requested information from the Company relating to certain elements of the Company’s cost accounting and indirect cost charging practices with the U.S. government. Since learning of the investigation, the Company has engaged a law firm experienced in these matters to represent the Company in connection with this matter and respond to the government's requests. As is commonly the case with this type of matter, the Company has also been in contact with other regulatory agencies and bodies, including the Securities and Exchange Commission, which notified the Company that it is conducting an investigation that the Company believes relates to the matters that are also the subject of the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are the subject of the DOJ's investigation. In accordance with the Company's practice, the Company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. At this stage, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with these matters.

On June 19, 2017, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Virginia styled Langley v. Booz Allen Hamilton Holding Corp., No. 17-cv-00696 naming the Company, its Chief Executive Officer and its Chief Financial Officer as defendants purportedly on behalf of all purchasers of the Company’s securities from May 19, 2016 through June 15, 2017. On September 5, 2017, the court named two lead plaintiffs, and on October 20, 2017, the lead plaintiffs filed a consolidated amended complaint. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, alleging misrepresentations or omissions by the Company purporting to relate to matters that are the subject of the DOJ investigation described above. The plaintiffs seek to recover from the Company and the individual defendants an unspecified amount of damages. The Company believes the suit lacks merit and intends to defend against the lawsuit. Motions to dismiss were argued on January 12, 2018, and on February 8, 2018, the court dismissed the amended complaint in its entirety without prejudice. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On November 13, 2017, a Verified Shareholder Derivative Complaint was filed in the United States District Court for the District of Delaware styled Celine Thum v. Rozanski et. al., C.A. No. 17-cv-01638, naming the Company as a nominal defendant and numerous current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, abuse of control, gross mismanagement, and violations of Sections 14(a), 10(b) and 20(a) of the Exchange Act, purportedly relating to matters that are the subject of the DOJ investigation described above. The parties have stipulated to a stay of the proceedings pending the outcome of the securities litigation (described above), which the court ordered on January 24, 2018. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

Financial and Other Highlights

Effective April 1, 2018, the Company adopted Accounting Standard Codification (ASC) No. 606, Revenue from Contracts with Customers (Topic 606), and Accounting Standard Updates (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, using the full retrospective method. All amounts, percentages and disclosures set forth in this Form 10-Q reflect these changes. See Note 2 to our accompanying condensed consolidated financial statements for more information on the impact of the adoption of these accounting standards on revenue and operating income.

During the second quarter of fiscal 2019, the Company generated year over year revenue growth, delivered improved earnings over the prior year period, increased client staff headcount, and achieved record second quarter funded and total backlog.

26

Revenue increased 4.6% from the three months ended September 30, 2017 to the three months ended September 30, 2018 and increased 6.4% from the six months ended September 30, 2017 to the six months ended September 30, 2018 primarily driven by continued strength in client demand, which led to increased client staff headcount and direct client staff labor over the prior year period, as well as improved contract performance.

Operating income increased 8.2% to $143.8 million in the three months ended September 30, 2018 from $132.9 million in the three months ended September 30, 2017, while operating margin increased to 8.9% from 8.6% in the comparable period. Operating income increased 17.6% to $305.4 million in the six months ended September 30, 2018 from $259.6 million in the six months ended September 30, 2017, while operating margin increased to 9.4% from 8.5% in the comparable period. The increase in operating income was primarily driven by the same factors driving revenue as well as strong operating performance in the current quarter compared to the prior year quarter. The Company also incurred incremental legal costs during the three and six months ended September 30, 2018 in response to the U.S. Department of Justice investigation and matters which purport to relate to the investigation, a portion of which was offset by the receipt of insurance reimbursements. We expect to incur additional costs in the future. Based on the information currently available, the Company is not able to reasonably estimate the expected long-term incremental legal costs or amounts that may be reimbursed associated with this investigation and these related matters.

Non-GAAP Measures

We publicly disclose certain non-GAAP financial measurements, including Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted Earnings Per Share, or Adjusted Diluted EPS, because management uses these measures for business planning purposes, including to manage our business against internal projected results of operations and measure our performance. We view Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted EPS as measures of our core operating business, which exclude the impact of the items detailed below, as these items are generally not operational in nature. These non-GAAP measures also provide another basis for comparing period to period results by excluding potential differences caused by non-operational and unusual or non-recurring items. In addition, we use Revenue, Excluding Billable Expenses because it provides management useful information about the Company's operating performance by excluding the impact of costs that are not indicative of the level of productivity of our consulting staff headcount and our overall direct labor, which management believes provides useful information to our investors about our core operations. We also utilize and discuss Free Cash Flow, because management uses this measure for business planning purposes, measuring the cash generating ability of the operating business, and measuring liquidity generally. We present these supplemental measures because we believe that these measures provide investors and securities analysts with important supplemental information with which to evaluate our performance, long term earnings potential, or liquidity, as applicable, and to enable them to assess our performance on the same basis as management. These supplemental performance measurements may vary from and may not be comparable to similarly titled measures by other companies in our industry. Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow are not recognized measurements under accounting principles generally accepted in the United States, or GAAP, and when analyzing our performance or liquidity, as applicable, investors should (i) evaluate each adjustment in our reconciliation of revenue to Revenue, Excluding Billable Expenses, operating income to Adjusted Operating Income, net income to Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income and Adjusted Diluted EPS, and net cash provided by operating activities to Free Cash Flow, (ii) use Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, and Adjusted Diluted EPS in addition to, and not as an alternative to, revenue, operating income, net income or diluted EPS, as measures of operating results, each as defined under GAAP and (iii) use Free Cash Flow in addition to, and not as an alternative to, net cash provided by operating activities as a measure of liquidity, each as defined under GAAP. We have defined the aforementioned non-GAAP measures as follows:

• "Revenue, Excluding Billable Expenses" represents revenue less billable expenses. We use Revenue, Excluding Billable Expenses because it provides management useful information about the Company's operating performance by excluding the impact of costs that are not indicative of the level of productivity of our consulting staff headcount and our overall direct labor, which management believes provides useful information to our investors about our core operations.

• "Adjusted Operating Income" represents operating income before: (i) adjustments related to the amortization of intangible assets resulting from the acquisition of our Company by The Carlyle Group (the “Carlyle Acquisition”), and (ii) transaction costs, fees, losses, and expenses, including fees associated with debt

27

prepayments. We prepare Adjusted Operating Income to eliminate the impact of items we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature.

• "Adjusted EBITDA” represents net income before income taxes, net interest and other expense and depreciation and amortization before certain other items, including transaction costs, fees, losses, and expenses, including fees associated with debt prepayments. “Adjusted EBITDA Margin on Revenue” is calculated as Adjusted EBITDA divided by revenue. "Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses" is calculated as Adjusted EBITDA divided by Revenue, Excluding Billable Expenses. The Company prepares Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, and Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses to eliminate the impact of items it does not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary or non-recurring nature or because they result from an event of a similar nature.

• "Adjusted Net Income" represents net income before: (i) adjustments related to the amortization of intangible assets resulting from the Carlyle Acquisition, (ii) transaction costs, fees, losses, and expenses, including fees associated with debt prepayments, (iii) amortization or write-off of debt issuance costs and write-off of original issue discount, (iv) release of income tax reserves, and (v) re-measurement of deferred tax assets andliabilities as a result of the Tax Cuts and Jobs Act (the "2017 Tax Act") in each case net of the tax effect where appropriate calculated using an assumed effective tax rate. We prepare Adjusted Net Income to eliminate the impact of items, net of tax, we do not consider indicative of ongoing operating performance due to their inherent unusual, extraordinary, or non-recurring nature or because they result from an event of a similar nature. We view net income excluding the impact of the re-measurement of the Company's deferred tax assets and liabilities as a result of the 2017 Tax Act as an important indicator of performance consistent with the manner in which management measures and forecasts the Company's performance and the way in which management is incentivized to perform.

• "Adjusted Diluted EPS" represents diluted EPS calculated using Adjusted Net Income as opposed to net income. Additionally, Adjusted Diluted EPS does not contemplate any adjustments to net income as required under the two-class method as disclosed in the footnotes to the condensed consolidated financial statements.

• "Free Cash Flow" represents the net cash generated from operating activities less the impact of purchases of property and equipment.

28

Below is a reconciliation of Revenue, Excluding Billable Expenses, Adjusted Operating Income, Adjusted EBITDA, Adjusted EBITDA Margin on Revenue, Adjusted EBITDA Margin on Revenue, Excluding Billable Expenses, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow to the most directly comparable financial measure calculated and presented in accordance with GAAP.

Factors and Trends Affecting Our Results of Operations

Our results of operations have been, and we expect them to continue to be, affected by the following factors, which may cause our future results of operations to differ from our historical results of operations discussed under “— Results of Operations.”

Business Environment and Key Trends in Our Markets

We believe that the following trends and developments in the U.S. government services industry and our markets may influence our future results of operations:

• uncertainty around the timing, extent, nature and effect of Congressional and other U.S. government actions to approve funding of the U.S. government, address budgetary constraints, including caps on the discretionary budget for defense and non-defense departments and agencies, as established by the Bipartisan Budget Control Act of 2011 and subsequently adjusted by the American Tax Payer Relief Act of 2012, the Bipartisan Budget Act of 2013 and the Bipartisan Budget Act of 2015, and address the ability of Congress to determine how to allocate the available budget authority and pass appropriations bills to fund both U.S. government departments and agencies that are, and those that are not, subject to the caps;

• budget deficits and the growing U.S. national debt increasing pressure on the U.S. government to reduce federal spending across all federal agencies together with associated uncertainty about the size and timing of those reductions;

• cost cutting and efficiency initiatives, current and future budget restrictions, continued implementation of Congressionally mandated automatic spending cuts and other efforts to reduce U.S. government spending could cause clients to reduce or delay funding for orders for services or invest appropriated funds on a less consistent or rapid basis or not at all, particularly when considering long-term initiatives and in light of current uncertainty around Congressional efforts to approve funding of the U.S. government and to craft a long-term agreement on the U.S. government's ability to incur indebtedness in excess of its current limits and generally in the current political environment, there is a risk that clients will not issue task orders in sufficient volume to reach current contract ceilings, alter historical patterns of contract awards, including the typical increase in the award of task orders or completion of other contract actions by the U.S. government in the period before the end of the U.S. government's fiscal year on September 30, delay requests for new proposals and contract awards, rely on short-term extensions and funding of current contracts, or reduce staffing levels and hours of operation;

• delays in the completion of future U.S. government’s budget processes, which have in the past and could in the future delay procurement of the products, services, and solutions we provide;

• changes in the relative mix of overall U.S. government spending and areas of spending growth, with lower spending on homeland security, intelligence and defense-related programs as certain overseas operations end, and continued increased spending on cyber-security, Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR), advanced analytics, technology integration and healthcare;

• legislative and regulatory changes to limitations on the amount of allowable executive compensation permitted under flexibly priced contracts following implementation of interim rules adopted by federal agencies pursuant to the Bipartisan Budget Act of 2013, which substantially further reduce the amount of allowable executive compensation under these contracts and extend these limitations to a larger segment of our executives and our entire contract base;

• efforts by the U.S. government to address organizational conflicts of interest and related issues and the impact of those efforts on us and our competitors;

• increased audit, review, investigation and general scrutiny by U.S. government agencies of government contractors' performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws;

• the federal focus on refining the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments, which will continue to drive pockets of insourcing in various agencies, particularly in the intelligence market;

• negative publicity and increased scrutiny of government contractors in general, including us, relating to U.S. government expenditures for contractor services and incidents involving the mishandling of sensitive or classified information;

31

• U.S. government agencies awarding contracts on a technically acceptable/lowest cost basis, which could have a negative impact on our ability to win certain contracts;

• increased competition from other government contractors and market entrants seeking to take advantage of certain of the trends identified above, and an industry trend towards consolidation, which may result in the emergence of companies that are better able to compete against us;

• cost cutting and efficiency and effectiveness efforts by U.S. civilian agencies with a focus on increased use of performance measurement, “program integrity” efforts to reduce waste, fraud and abuse in entitlement programs, and renewed focus on improving procurement practices for and interagency use of IT services, including through the use of cloud based options and data center consolidation;

• restrictions by the U.S. government on the ability of federal agencies to use lead system integrators, in response to cost, schedule and performance problems with large defense acquisition programs where contractors were performing the lead system integrator role;

• increasingly complex requirements of the Department of Defense and the U.S. Intelligence Community, including cyber-security, managing federal health care cost growth and focus on reforming existing government regulation of various sectors of the economy, such as financial regulation and healthcare; and

• increasing small business regulations across the Department of Defense and civilian agency clients continue to gain traction whereby agencies are required to meet high small business set aside targets, and large business prime contractors are required to subcontract in accordance with considerable small business participation goals necessary for contract award.

Sources of Revenue

Substantially all of our revenue is derived from services provided under contracts and task orders with the U.S. government, primarily by our consulting staff and, to a lesser extent, our subcontractors. Funding for our contracts and task orders is generally linked to trends in budgets and spending across various U.S. government agencies and departments. We provide services under a large portfolio of contracts and contract vehicles to a broad client base, and we believe that our diversified contract and client base lessens potential volatility in our business; however, a reduction in the amount of services that we are contracted to provide to the U.S. government or any of our significant U.S. government clients could have a material adverse effect on our business and results of operations. In particular, the Department of Defense is one of our significant clients, and the Budget Control Act (BCA) of 2011 (as amended by the American Taxpayer Relief Act of 2012, the Bipartisan Budget Act of 2013, the Bipartisan Budget Act of 2015, and the Bipartisan Budget Act of 2018), provides for automatic spending cuts (referred to as sequestration) totaling approximately $1.2 trillion between 2013 and 2021, including an estimated $500 billion in federal defense spending cuts over this time period. The Bipartisan Budget Act of 2018 raised BCA spending caps on defense spending by $80 billion for government fiscal 2018, and $85 billion for government fiscal 2019. For non-defense funding, the Bipartisan Budget Act of 2018 raised BCA spending caps by $63 billion for fiscal 2018 and $67 billion for government fiscal 2019. While the American Taxpayer Relief Act of 2012, the Bipartisan Budget Act of 2013, the Bipartisan Budget Act of 2015, and the Bipartisan Budget Act of 2018 all negated and raised budget limits put in place by the BCA for both defense and non-defense spending, those spending limits are due to return in fiscal 2020, and absent another budget deal, could result in significant cuts to the budget levels allowed by the Bipartisan Budget Act of 2018. This could result in a commensurate reduction in the amount of services that we are contracted to provide to the Department of Defense and could have a material adverse effect on our business and results of operations, and, given the uncertainty of when and how these automatic reductions required by the BCA may return and/or be applied, we are unable to predict the nature or magnitude of the potential adverse effect.

Contract Types

We generate revenue under the following three basic types of contracts:

• Cost-Reimbursable Contracts. Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee. As we increase or decrease our spending on allowable costs, our revenue generated on cost-reimbursable contracts will increase, up to the ceiling and funded amounts, or decrease, respectively. We generate revenue under two general types of cost-reimbursable contracts: cost-plus-fixed-fee and cost-plus-award-fee, both of which reimburse allowable costs and provide for a fee. The fee under each type of cost-reimbursable contract is generally payable upon completion of services in accordance with the terms of the contract. Cost-plus-fixed-fee contracts offer no opportunity for payment beyond the fixed fee. Cost-plus-award-fee contracts also provide for an award fee that varies within specified limits based upon the client's

32

assessment of our performance against a predetermined set of criteria, such as targets for factors like cost, quality, schedule, and performance.

• Time-and-Materials Contracts. Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates. To the extent our actual direct labor, including allocated indirect costs, and associated billable expenses decrease or increase in relation to the fixed hourly billing rates provided in the contract, we will generate more or less profit, respectively, or could incur a loss.

• Fixed-Price Contracts. Under a fixed-price contract, we agree to perform the specified work for a pre-determined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss. Some fixed-price contracts have a performance-based component, pursuant to which we can earn incentive payments or incur financial penalties based on our performance.

The amount of risk and potential reward varies under each type of contract. Under cost-reimbursable contracts, there is limited financial risk, because we are reimbursed for all allowable costs up to a ceiling. However, profit margins on this type of contract tend to be lower than on time-and-materials and fixed-price contracts. Under time-and-materials contracts, we are reimbursed for the hours worked using the predetermined hourly rates for each labor category. In addition, we are typically reimbursed for other contract direct costs and expenses at cost. We assume financial risk on time-and-materials contracts because our labor costs may exceed the negotiated billing rates. Profit margins on well-managed time-and-materials contracts tend to be higher than profit margins on cost-reimbursable contracts as long as we are able to staff those contracts with people who have an appropriate skill set. Under fixed-price contracts, we are required to deliver the objectives under the contract for a pre-determined price. Compared to time-and-materials and cost-reimbursable contracts, fixed-price contracts generally offer higher profit margin opportunities because we receive the full benefit of any cost savings but generally involve greater financial risk because we bear the impact of any cost overruns. In the aggregate, the contract type mix in our revenue for any given period will affect that period's profitability. Changes in contract type as a result of re-competes and new business could influence the percentage/mix in unanticipated ways.

The table below presents the percentage of total revenue for each type of contract:

	Three Months Ended September 30,		Six Months Ended September 30,
	2018	2017	2018	2017
Cost-reimbursable	53%	52%	53%	51%
Time-and-materials	24%	25%	24%	25%
Fixed-price	23%	23%	23%	24%

Note: Upon the adoption of Topic 606 in the current period, the contract type descriptions noted above have been aligned to the Revenue by Contract Type descriptions found in Note 3 to our accompanying condensed consolidated financial statements.

Contract Diversity and Revenue Mix

We provide services to our clients through a large number of single award contracts, contract vehicles, and multiple award contract vehicles. Most of our revenue is generated under indefinite delivery/indefinite quantity, or IDIQ, contract vehicles, which include multiple award government wide acquisition contract vehicles, or GWACs, and General Services Administration Multiple Award Schedule Contracts, or GSA schedules, and certain single award contracts. GWACs and GSA schedules are available to all U.S. government agencies. Any number of contractors typically compete under multiple award IDIQ contract vehicles for task orders to provide particular services, and we earn revenue under these contract vehicles only to the extent that we are successful in the bidding process for task orders.

We generate revenue under our contracts and task orders through our provision of services as both a prime contractor and subcontractor, as well as from the provision of services by subcontractors under contracts and task orders for which we act as the prime contractor. The mix of these types of revenue affects our operating margin. Substantially all of our operating margin is derived from direct consulting staff labor, as the portion of our operating margin derived from fees we earn on services provided by our subcontractors is not significant. We view growth in direct consulting staff labor as the primary driver of earnings growth. Direct consulting staff labor growth is driven by consulting staff headcount growth, after attrition, and total backlog growth.

33

Our People

Revenue from our contracts is derived from services delivered by consulting staff and, to a lesser extent, from our subcontractors. Our ability to hire, retain, and deploy talent with skills appropriately aligned with client needs is critical to our ability to grow our revenue. We continuously evaluate whether our talent base is properly sized and appropriately compensated, and contains an optimal mix of skills to be cost competitive and meet the rapidly evolving needs of our clients. We seek to achieve that result through recruitment and management of capacity and compensation. As of September 30, 2018 and 2017, we employed approximately 25,300 and 24,200 people, respectively, of which approximately 22,800 and 21,800, respectively, were consulting staff.

Contract Backlog

We define backlog to include the following three components:

• Funded Backlog. Funded backlog represents the revenue value of orders for services under existing contracts for which funding is appropriated or otherwise authorized less revenue previously recognized on these contracts.

• Unfunded Backlog. Unfunded backlog represents the revenue value of orders (including optional orders) for services under existing contracts for which funding has not been appropriated or otherwise authorized.

• Priced Options. Priced contract options represent 100% of the revenue value of all future contract option periods under existing contracts that may be exercised at our clients' option and for which funding has not been appropriated or otherwise authorized.

Backlog does not include any task orders under IDIQ contracts, except to the extent that task orders have been awarded to us under those contracts.

The following table summarizes the value of our contract backlog at the respective dates presented:

	As of September 30,
	2018		2017
	(In millions)
Backlog:
Funded	$	4,183	$	3,590
Unfunded	4,777		3,861
Priced options	12,412		9,234
Total backlog	$	21,372	$	16,685

Our total backlog consists of remaining performance obligations and unexercised option periods and other unexercised optional orders. As of September 30, 2018, the Company had $7.8 billion of remaining performance obligations and we expect to recognize more than half of the remaining performance obligations as revenue over the next 12 months, and approximately three quarters over the next 24 months. The remainder is expected to be recognized thereafter. However, given the uncertainties discussed below, as well as the risks described in "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended March 31, 2018, we can give no assurance that we will be able to convert our backlog into revenue in any particular period, if at all.

Our backlog includes orders under contracts that in some cases extend for several years. The U.S. Congress generally appropriates funds for our clients on a yearly basis, even though their contracts with us may call for performance that is expected to take a number of years to complete. As a result, contracts typically are only partially funded at any point during their term and all or some of the work to be performed under the contracts may remain unfunded unless and until the U.S. Congress makes subsequent appropriations and the procuring agency allocates funding to the contract.

We view growth in total backlog and consulting staff headcount as the two key measures of our potential business growth. Growing and deploying consulting staff is the primary means by which we are able to achieve profitable revenue growth. To the extent that we are able to hire additional consulting staff and deploy them against funded backlog, we generally recognize increased revenue. Total backlog increased by 28.1% from September 30, 2017 to September 30, 2018. Additions to funded backlog during the twelve months ended September 30, 2018 totaled $7.0 billion in comparison to $6.2 billion for the comparable period, as a result of the conversion of unfunded backlog to funded backlog, the award of new contracts and task orders under which funding was appropriated, and the exercise and subsequent funding of priced options. We report internally on our backlog on a monthly basis and review backlog upon occurrence of certain events to determine if any adjustments are necessary.

34

We cannot predict with any certainty the portion of our backlog that we expect to recognize as revenue in any future period and we cannot guarantee that we will recognize any revenue from our backlog. The primary risks that could affect our ability to recognize such revenue on a timely basis or at all are: program schedule changes, contract modifications, and our ability to assimilate and deploy new consulting staff against funded backlog; cost cutting initiatives and other efforts to reduce U.S. government spending, which could reduce or delay funding for orders for services; and delayed funding of our contracts due to delays in the completion of the U.S. government's budgeting process and the use of continuing resolutions by the U.S. government to fund its operations. The amount of our funded backlog is also subject to change, due to, among other factors: changes in congressional appropriations that reflect changes in U.S. government policies or priorities resulting from various military, political, economic or international developments; changes in the use of U.S. government contracting vehicles; and the provisions therein used to procure our services and adjustments to the scope of services, or cancellation of contracts, by the U.S government at any time. In our recent experience, none of the following additional risks have had a material negative effect on our ability to realize revenue from our funded backlog: the unilateral right of the U.S. government to cancel multi-year contracts and related orders or to terminate existing contracts for convenience or default: in the case of unfunded backlog, the potential that funding will not be made available; and, in the case of priced options, the risk that our clients will not exercise their options.

In addition, funded backlog includes orders under contracts for which the period of performance has expired, and we may not recognize revenue on the funded backlog that includes such orders due to, among other reasons, the tardy submission of invoices by our subcontractors and the expiration of the relevant appropriated funding in accordance with a pre-determined expiration date such as the end of the U.S. government's fiscal year. The revenue value of orders included in funded backlog that has not been recognized as revenue due to period of performance expirations has not exceeded approximately 7.9% of funded backlog as of the end of any of the four fiscal quarters preceding the fiscal quarter ended September 30, 2018.

Operating Costs and Expenses

Costs associated with compensation and related expenses for our people are the most significant component of our operating costs and expenses. The principal factors that affect our costs are additional people as we grow our business and are awarded new contracts, task orders, and additional work under our existing contracts, and the hiring of people with specific skill sets and security clearances as required by our additional work.

Our most significant operating costs and expenses are described below.

• Cost of Revenue. Cost of revenue includes direct labor, related employee benefits, and overhead. Overhead consists of indirect costs, including indirect labor relating to infrastructure, management and administration, and other expenses.

• Billable Expenses. Billable expenses include direct subcontractor expenses, travel expenses, and other expenses incurred to perform on contracts.

• General and Administrative Expenses. General and administrative expenses include indirect labor of executive management and corporate administrative functions, marketing and bid and proposal costs, legal expenses, and other discretionary spending.

• Depreciation and Amortization. Depreciation and amortization includes the depreciation of computers, leasehold improvements, furniture and other equipment, and the amortization of internally developed software, as well as third-party software that we use internally, and of identifiable long-lived intangible assets over their estimated useful lives.

Seasonality

The U.S. government's fiscal year ends on September 30 of each year. While not certain, it is not uncommon for U.S. government agencies to award extra tasks or complete other contract actions in the weeks before the end of its fiscal year in order to avoid the loss of unexpended fiscal year funds. In addition, we also have historically experienced higher bid and proposal costs in the months leading up to the U.S. government's fiscal year end as we pursue new contract opportunities being awarded shortly after the U.S. government fiscal year end as new opportunities are expected to have funding appropriated in the U.S. government's subsequent fiscal year. We may continue to experience this seasonality in future periods, and our future periods may be affected by it. While not certain, changes in the government's funding and spending patterns have altered historical seasonality trends, supporting our approach to managing the business on an annual basis.

Three Months Ended September 30, 2018 Compared to Three Months Ended September 30, 2017

Revenue

Revenue increased to $1,614.0 million from $1,542.8 million, or a 4.6% increase, primarily driven by increased client demand which led to increased client staff headcount, and an increase in client staff labor as well as improved contract performance. Total headcount as of September 30, 2018 increased approximately 1,100 compared to September 30, 2017.

Cost of Revenue

Cost of revenue increased to $748.6 million from $696.7 million, or a 7.4% increase. The increase was primarily due to increases in salaries and salary-related benefits of $48.7 million driven by increased headcount and annual base salary increases. Cost of revenue as a percentage of revenue was 46.4% and 45.2% for the three months ended September 30, 2018 and 2017, respectively.

Billable Expenses

Billable expenses decreased to $478.3 million from $483.6 million, or a 1.1% decrease, primarily attributable to a decrease in the use of subcontractors in the current quarter driven by client demand, partially offset by an increase in contracts which require the Company to travel on behalf of clients over the prior year period. Billable expenses as a percentage of revenue were 29.6% and 31.3% for the three months ended September 30, 2018 and 2017, respectively.

36

General and Administrative Expenses

General and administrative expenses increased to $226.9 million from $213.6 million, or a 6.2% increase, primarily due to increases in salaries and salary-related benefits of $4.9 million, driven by an increase in headcount growth as well as annual base salary increases, and an increase in other business expenses of $5.2 million. General and administrative expenses as a percentage of revenue were 14.1% and 13.8% for the three months ended September 30, 2018 and 2017, respectively.

Depreciation and Amortization

Depreciation and amortization increased to $16.4 million from $16.0 million, or a 2.4% increase, primarily due to increases in depreciation expense resulting from the effects of higher capital expenditures in fiscal 2018.

Interest Expense

Interest expense increased to $22.2 million from $21.0 million, or a 6.2% increase, primarily as a result of increases in interest expense related to our term loans.

Income Tax Expense

Income tax expense decreased to $27.2 million from $36.9 million, or a 26.4% decrease. The effective tax rate decreased to 22.7% from 33.4% primarily due to the 2017 Tax Act's reduction of the U.S. federal corporate tax rate.

Six Months Ended September 30, 2018 Compared to Six Months Ended September 30, 2017

Revenue

Revenue increased to $3,260.8 million from $3,065.8 million, or a 6.4% increase, primarily driven by increased client demand which led to increased client staff headcount, and an increase in client staff labor as well as improved contract performance. Revenue growth was also driven by an increase in billable expenses, including subcontractors and travel on behalf of our clients.

Cost of Revenue

Cost of revenue increased to $1,534.4 million from $1,432.5 million, or a 7.1% increase. The increase was primarily due to increases in salaries and salary-related benefits of $89.5 million driven by increased headcount and annual base salary increases. Cost of revenue as a percentage of revenue was 47.1% and 46.7% for the six months ended September 30, 2018 and 2017, respectively.

Billable Expenses

Billable expenses increased to $955.8 million from $935.2 million, or a 2.2% increase, primarily attributable to an increase in the use of subcontractors in the current year driven by client demand, as well as an increase in contracts which require the Company to travel and incur direct expenses on behalf of clients over the prior year period. Billable expenses as a percentage of revenue were 29.3% and 30.5% for the six months ended September 30, 2018 and 2017, respectively.

General and Administrative Expenses

General and administrative expenses increased to $432.7 million from $407.1 million, or a 6.3% increase, primarily due to increases in salaries and salary-related benefits of $12.4 million, driven by an increase in headcount growth as well as annual base salary increases, and an increase in professional fees of $3.7 million. General and administrative expenses as a percentage of revenue were 13.3% for both the six months ended September 30, 2018 and 2017, respectively.

Depreciation and Amortization

Depreciation and amortization increased to $32.6 million from $31.5 million, or a 3.4% increase, primarily due to increases in depreciation expense resulting from the effects of higher capital expenditures in fiscal 2018.

Interest Expense

Interest expense increased to $45.3 million from $39.7 million, or a 14.1% increase, primarily as a result of increases in interest expense related to our term loans, and the Senior Notes.

Income Tax Expense

Income tax expense decreased to $60.3 million from $73.1 million, or a 17.5% decrease. The effective tax rate decreased to 23.5% from 33.6% primarily due to the 2017 Tax Act's reduction of the U.S. federal corporate tax rate.

Liquidity and Indebtedness

The following table presents selected financial information as of September 30, 2018 and March 31, 2018 and for the first six months of fiscal 2019 and 2018:

	September 30, 2018			March 31, 2018
	(Unaudited)
	(In thousands)
Cash and cash equivalents	$	342,586		$	286,958
Total debt	1,786,799			1,818,579
	Six Months Ended September 30,
	2018			2017
	(Unaudited)			(Unaudited)
	(In thousands)
Net cash provided by operating activities	$	274,567		$	178,062
Net cash used in investing activities	(39,692		)	(37,193		)
Net cash used in financing activities	(179,247		)	(28,243		)
Total increase in cash and cash equivalents	$	55,628		$	112,626

From time to time, we evaluate alternative uses for excess cash resources once our operating cash flow and required debt servicing needs have been met. Some of the possible uses of our remaining excess cash at any point in time may include funding strategic acquisitions, further investment in our business and returning value to shareholders through share repurchases, quarterly dividends, and special dividends. While the timing and financial magnitude of these possible actions are currently indeterminable, the Company expects to be able to manage and adjust its capital structure in the future to meet its liquidity needs.

Historically, we have been able to generate sufficient cash to fund our operations, mandatory debt and interest payments, capital expenditures, and discretionary funding needs. However, due to fluctuations in cash flows, including as a result of the trends and developments described above under "—Factors and Trends Affecting Our Results of Operations" relating to U.S. government cost-cutting, reductions or delays in the U.S. government appropriations and spending process and other budgetary matters, it may be necessary from time-to-time in the future to borrow under our Secured Credit Facility to meet cash demands. While the timing and financial magnitude of these possible actions are currently indeterminable, we expect to be able to manage and adjust our capital structure to meet our liquidity needs. Our expected liquidity and capital structure may also be impacted by discretionary investments and acquisitions that we could pursue. We anticipate that cash provided by operating activities, existing cash and cash equivalents, and borrowing capacity under our revolving credit facility will be sufficient to meet our anticipated cash requirements for the next twelve months, which primarily include:

• operating expenses, including salaries;

• working capital requirements to fund the growth of our business;

• capital expenditures which primarily relate to the purchase of computers, business systems, furniture and leasehold improvements to support our operations;

• commitments and other discretionary investments;

• debt service requirements for borrowings under our Secured Credit Facility and interest payments for the Senior Notes; and

• cash taxes to be paid.

Our ability to fund our operating needs depends, in part, on our ability to continue to generate positive cash flows from operations or, if necessary, raise cash in the capital markets.

38

Cash Flows

Cash received from clients, either from the payment of invoices for work performed or for advances in excess of costs incurred, is our primary source of cash. We generally do not begin work on contracts until funding is appropriated by the client. Billing timetables and payment terms on our contracts vary based on a number of factors, including whether the contract type is cost-reimbursable, time-and-materials, or fixed-price. We generally bill and collect cash more frequently under cost-reimbursable and time-and-materials contracts, as we are authorized to bill as the costs are incurred or work is performed. In contrast, we may be limited to bill certain fixed-price contracts only when specified milestones, including deliveries, are achieved. In addition, a number of our contracts may provide for performance-based payments, which allow us to bill and collect cash prior to completing the work.

Accounts receivable is the principal component of our working capital and is generally driven by revenue growth with other short-term fluctuations related to the payment practices of our clients. Our accounts receivable reflects amounts billed to our clients as of each balance sheet date. Our U.S government customers generally pay our invoices within 30 days of the invoice date, while we experience a longer billing and collection cycle with our global commercial customers. At any month-end, we also include in accounts receivable the revenue that was recognized in the preceding month, which is generally billed early in the following month. Finally, we include in accounts receivable amounts related to revenue accrued in excess of amounts billed, primarily on our fixed-price and cost-reimbursable-plus-award-fee contracts. The total amount of our accounts receivable can vary significantly over time, but is generally sensitive to revenue levels and customer mix. Total accounts receivable (billed and unbilled combined, net of allowance for doubtful accounts) days sales outstanding, or DSO, which we calculate by dividing total accounts receivable by revenue per day during the relevant fiscal quarter, was 70 as of September 30, 2018 and 66 as of March 31, 2018. DSO increased primarily due to delays in the billing and collection of our revenue growth, which includes administrative delays in client payment processing.

Operating Cash Flow

Net cash provided by operations is primarily affected by the overall profitability of our contracts, our ability to invoice and collect cash from clients in a timely manner, our ability to manage our vendor payments and the timing of cash paid for income taxes. Continued uncertainty in global economic conditions may also affect our business as customers and suppliers may decide to downsize, defer, or cancel contracts, which could negatively affect the operating cash flows. Net cash provided by operations was $274.6 million in the six months ended September 30, 2018 compared to $178.1 million in the prior year period. The increase in operating cash flows was primarily due to increased efficiencies related to working capital and increased operating cash that aligns with net income growth over the same period.

Investing Cash Flow

Net cash used in investing activities was $39.7 million in the six months ended September 30, 2018 compared to $37.2 million in the prior year period, or a 6.7% increase. The increase in net cash used in investing activities was due to an increase in capital expenditures over the prior year period primarily related to software purchased and developed for clients and for operating performance.

Financing Cash Flow

Net cash used in financing activities was $179.2 million in the six months ended September 30, 2018 compared to $28.2 million in the prior year period. The increase in net cash used in financing activities was primarily due to net proceeds of $343.3 million received in fiscal 2018 from the issuance of the Senior Notes. This was partially offset by $130.0 million in net borrowings on the Revolving Credit Facility in the prior period as well as a $70.1 million decrease in share repurchases compared to the prior period.

Dividends and Share Repurchases

On October 29, 2018, the Company announced a regular quarterly cash dividend in the amount of $0.19 per share. The quarterly dividend is payable on November 30, 2018 to stockholders of record on November 14, 2018.

The following table summarizes the cash distributions recognized in the condensed consolidated statement of cash flows:

	Three Months Ended September 30,				Six Months Ended September 30,
	2018		2017		2018		2017
Quarterly dividends (1)	$	27,218	$	25,454	$	54,660	$	50,866
Dividend equivalents (2)	—		—		267		890
Total distributions	$	27,218	$	25,454	$	54,927	$	51,756

39

(1) Amounts represent quarterly dividends of $0.19 per share and $0.17 per share that were declared and paid during fiscal 2019 and fiscal 2018, respectively.

(2) Dividend equivalents are distributions made to option holders equal to the previously declared special dividends.

On December 12, 2011, the Board of Directors authorized the repurchase of up to $30.0 million of shares. On January 27, 2015, the share repurchase authorization was increased to $180.0 million. On January 25, 2017, the Board of Directors approved an increase to share repurchase authorization from $180.0 million to $410.0 million. On November 2, 2017, the Board of Directors approved an increase to our share repurchase authorization from $410.0 million to up to $610.0 million. On May 24, 2018, the Board of Directors approved an increase to our share repurchase authorization from $610.0 million to up to $910.0 million. The Company may repurchase shares pursuant to the program by means of open market repurchases, directly negotiated repurchases or through agents acting pursuant to negotiated repurchase agreements. During the first and second quarters of fiscal 2019, the Company purchased 1.9 million shares of the Company's Class A Common Stock for an aggregate of $85.4 million. Following the aforementioned repurchases, as of September 30, 2018, the Company had $412.5 million remaining under the repurchase program.

Any determination to pursue one or more of the above alternative uses for excess cash is subject to the discretion of our Board of Directors, and will depend upon various factors, including our results of operations, financial condition, liquidity requirements, restrictions that may be imposed by applicable law, our contracts, and our Credit Agreement and other factors deemed relevant by our Board of Directors.

Indebtedness

On July 23, 2018 (the "Amendment Effective Date"), Booz Allen Hamilton Inc. ("Booz Allen Hamilton") and Booz Allen Hamilton Investor Corporation ("Investor"), and certain wholly-owned subsidiaries of Booz Allen Hamilton, entered into the Sixth Amendment (the "Sixth Amendment") to the Credit Agreement (as amended, the "Credit Agreement"), dated as of July 31, 2012 among Booz Allen Hamilton, Investor, certain wholly-owned subsidiaries of Booz Allen Hamilton and Bank of America, N.A., as Administrative Agent and Collateral Agent and the other lenders and financial institutions from time to time party thereto (as previously amended by the First Amendment to Credit Agreement, dated as of August 16, 2013, the Second Amendment to the Credit Agreement, dated as of May 7, 2014, the Third Amendment to the Credit Agreement, dated as of July 13, 2016, the Fourth Amendment to the Credit Agreement, dated as of February 6, 2017, and the Fifth Amendment to the Credit Agreement, dated as of March 7, 2018). The Sixth Amendment provides for a new delayed draw (the "Delayed Draw Facility") on the tranche A term loan ("Term Loan A") facility in the amount of up to $400.0 million and extended the maturity of the Term Loan A and the revolving credit facility (the "Revolving Credit Facility") to July 2023. Additionally, the Sixth Amendment reduced the interest rate spread applicable to the Term Loan A and the Revolving Credit Facility from a range of 1.50% to 2.25% to a range of 1.25% to 2.00% based on consolidated net total leverage. The interest rate applicable to the Term Loan B ("Term Loan B" and, together with Term Loan A, the "Term Loans") remained unchanged.

Prior to the Sixth Amendment, approximately $1,079.5 million was outstanding under Term Loan A. Pursuant to the Sixth Amendment, certain lenders converted their existing Term Loan A loans into a new tranche of Term Loan A loans in an aggregate amount, along with Term Loan A loans advanced by certain new lenders, of approximately, $1,479.5 million, up to $400.0 million of which will be available as the Delayed Draw Facility. The Delayed Draw Facility is accessible for nine months from the Amendment Effective Date (the "Delayed Draw Availability Period"). The Company is able to draw on the facility up to two times during the Delayed Draw Availability Period with a minimum of $100.0 million per draw. The proceeds from the new lenders were used to prepay in full all of the existing Term A Loans that were not converted into the new Term Loan A. The proceeds of Delayed Draw Facility will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

Prior to the Sixth Amendment, $500.0 million was available under the Revolving Credit Facility. Pursuant to the Sixth Amendment, certain lenders under the Credit Agreement converted their existing revolving commitments into a new tranche of revolving commitments (the "New Revolving Commitments" and the revolving credit loans made thereunder, the "New Revolving Loans") in an aggregate amount, along with the New Revolving Commitments of certain new lenders, of $500.0 million.

As of September 30, 2018, the Credit Agreement provided Booz Allen Hamilton with a $1,064.7 million Term Loan A, a $400.0 million Delayed Draw Facility, a $393.0 million Term Loan B, and $500.0 million in New Revolving Commitments with a sub-limit for letters of credit of $100.0 million. As of September 30, 2018, the maturity date of Term Loan A and the termination date for the Revolving Credit Facility was July 23, 2023 and the maturity date of Term Loan B was June 30, 2023. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Investor and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. Subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the Term Loans or the Revolving Credit Facility may be expanded (or a new term loan facility or revolving credit facility added to the existing facilities) by up to (i) the greater of (x) $627 million and (y) 100% of consolidated EBITDA of Booz Allen Hamilton, as of the end of the most recently ended four quarter period for which financial statements have been delivered pursuant to the Credit Agreement plus (ii) the aggregate principal amount under which pro forma consolidated net secured leverage remains less than or equal to 3.50:1.00.

At Booz Allen Hamilton's option, borrowings under the Secured Credit Facility bear interest based either on LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or, a base rate equal to the highest of (x) the administrative agent’s prime corporate rate, (y) the overnight federal funds rate plus 0.50% and (z) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. The applicable margin for Term Loan B is 2.00% for LIBOR loans and 1.00% for base rate loans. Unused commitments under the Revolving Credit Facility are subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio.

Booz Allen Hamilton occasionally borrows under our Revolving Credit Facility in anticipation of cash demands. During the first quarter of fiscal 2019, Booz Allen Hamilton accessed a total of $70.0 million of its $500.0 million Revolving Credit Commitments. As of September 30, 2018 and March 31, 2018, there were no amounts outstanding under the Revolving Credit Facility.

The Credit Agreement requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity.

Booz Allen Hamilton also has agreed to pay customary letter of credit and agency fees. As of September 30, 2018 and March 31, 2018, Booz Allen Hamilton was contingently liable under open standby letters of credit and bank guarantees issued by its banks in favor of third parties that totaled $9.3 million and $6.3 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At September 30, 2018 and March 31, 2018, approximately $1.0 million and $1.4 million, respectively, of these instruments reduced the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $15.0 million facility established in fiscal 2015 of which $6.7 million and $10.1 million, respectively, was available to Booz Allen Hamilton at September 30, 2018 and March 31, 2018. As of September 30, 2018, Booz Allen Hamilton had $499.0 million of capacity available for additional borrowings under the Revolving Credit Facility.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include limitations on the following, in each case subject to certain exceptions: (i) indebtedness and liens; (ii) mergers, consolidations or amalgamations, liquidations, wind-ups or dissolutions, and disposition of all or substantially all assets; (iii) dispositions of property; (iv) restricted payments; (v) investments; (vi) transactions with affiliates; (vii) change in fiscal periods; (viii) negative pledges; (ix) restrictive agreements; (x) line of business; and (xi) speculative hedging. The events of default include the following, in each case subject to certain exceptions: (a) failure to make required payments under the Secured Credit Facility; (b) material breaches of representations or warranties under the Secured Credit Facility; (c) failure to observe covenants or agreements under the Secured Credit Facility; (d) failure to pay or default under certain other material indebtedness; (e) bankruptcy or insolvency; (f) certain Employee Retirement Income Security Act, or ERISA events; (g) certain material judgments; (h) actual or asserted invalidity of the Guarantee and Collateral Agreements or the other security documents or failure of the guarantees or perfected liens thereunder; and (i) a change of control. In addition, we are required to meet certain financial covenants at each quarter end, namely Consolidated Net Total Leverage and Consolidated Net Interest Coverage Ratios. As of September 30, 2018 and March 31, 2018, we were compliant with these covenants.

Senior Notes

On April 25, 2017, Booz Allen Hamilton issued $350 million aggregate principal amount of its 5.125% Senior Notes due 2025 under an Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the “Subsidiary Guarantors”), and Wilmington Trust, National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, the Subsidiary Guarantors and the Trustee. A portion of the proceeds was used to repay all outstanding loans under the Revolving Credit Facility. We intend to use the remaining proceeds for working capital and other general corporate purposes, which may include the repayment of a portion or all of the outstanding DPO (See Note 8 in our condensed consolidated financial statements for additional information on our indebtedness).

Borrowings under the Term Loans and, if used, the Revolving Credit Facility, incur interest at a variable rate. In accordance with Booz Allen Hamilton's risk management strategy, between April 6, 2017 and May 24, 2017, Booz Allen Hamilton executed a series of interest rate swaps. As of September 30, 2018, Booz Allen Hamilton had interest rate swaps with an aggregate notional amount of $450 million. These instruments hedge the variability of cash outflows for interest payments on the floating portion of the term loan debt. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (See Note 9 in our condensed consolidated financial statements).

Capital Structure and Resources

Our stockholders’ equity amounted to $646.3 million as of September 30, 2018, an increase of $83.8 million compared to stockholders’ equity of $562.5 million as of March 31, 2018. The increase was primarily due to net income of $196.9 million in the six months ended September 30, 2018, stock-based compensation expense of $13.3 million, and stock option exercises of $8.5 million, partially offset by 89.2 million increase in treasury stock resulting from the repurchase of shares of our Class A Common Stock and $54.7 million in quarterly dividend payments during the six months ended September 30, 2018.

Off-Balance Sheet Arrangements

As of September 30, 2018, we did not have any material off-balance sheet arrangements.

Capital Expenditures

Since we do not own any of our facilities, our capital expenditure requirements primarily relate to the purchase of computers, business systems, furniture, and leasehold improvements to support our operations. Direct facility and equipment costs billed to clients are not treated as capital expenses. Our capital expenditures for the six months ended September 30, 2018 and 2017 were $39.7 million and $37.0 million, respectively, and the majority of such capital expenditures related to software purchased and developed, facilities infrastructure, equipment, and information technology. The increase in capital expenditures over the prior year period primarily related to software purchased and developed for clients and for operating performance. Expenditures for facilities infrastructure and equipment are generally incurred to support new and existing programs across our business. We also incur capital expenditures for information technology to support programs and general enterprise information technology infrastructure.

Commitments and Contingencies

We are subject to a number of reviews, investigations, claims, lawsuits, and other uncertainties related to our business. For a discussion of these items, refer to Note 18 to our condensed consolidated financial statements.

42

• delayed funding of our contracts due to uncertainty relating to funding of the U.S. government and a possible failure of Congressional efforts to approve such funding and to craft a long-term agreement on the U.S. government’s ability to incur indebtedness in excess of its current limits, or changes in the pattern or timing of government funding and spending (including those resulting from or related to cuts associated with sequestration);

• any issue that compromises our relationships with the U.S. government or damages our professional reputation, including negative publicity concerning government contractors in general or us in particular;

• changes in U.S. government spending, including a continuation of efforts by the U.S. government to decrease spending for management support service contracts, and mission priorities that shift expenditures away from agencies or programs that we support;

• changes in the mix of our contracts and our ability to accurately estimate or otherwise recover expenses, time, and resources for our contracts;

• continued efforts to change how the U.S. government reimburses compensation related costs and other expenses or otherwise limit such reimbursements, and an increased risk of compensation being deemed unallowable or payments being withheld as a result of U.S. government audit, review, or investigation;

• our ability to realize the full value of and replenish our backlog, generate revenue under certain of our contracts, and the timing of our receipt of revenue under contracts included in backlog;

• changes in estimates used in recognizing revenue;

• an inability to attract, train, or retain employees with the requisite skills and experience;

• an inability to timely hire, assimilate and effectively utilize our employees, ensure that employees obtain and maintain necessary security clearances and/or effectively manage our cost structure;

• the loss of members of senior management or failure to develop new leaders;

• misconduct or other improper activities from our employees or subcontractors, including the improper use or release of our clients' sensitive or classified information;

• increased insourcing by various U.S. government agencies due to changes in the definition of “inherently governmental” work, including proposals to limit contractor access to sensitive or classified information and work assignments;

• increased competition from other companies in our industry;

• failure to maintain strong relationships with other contractors, or the failure of contractors with which we have entered into a sub- or prime- contractor relationship to meet their obligations to us or our clients;

• inherent uncertainties and potential adverse developments in legal or regulatory proceedings, including litigation, audits, reviews, and investigations, which may result in materially adverse judgments, settlements, withheld payments, penalties, or other unfavorable outcomes including debarment, as well as disputes over the availability of insurance or indemnification;

• internal system or service failures and security breaches, including, but not limited to, those resulting from external cyber attacks on our network and internal systems;

• risks related to changes to our operating structure, capabilities, or strategy intended to address client needs, grow our business or respond to market developments;

• risks associated with increased competition, new relationships, clients, capabilities, and service offerings in our U.S. and international businesses;

43

• failure to comply with special U.S. government laws and regulations relating to our international operations;

• risks related to our indebtedness and credit facilities which contain financial and operating covenants;

• the adoption by the U.S. government of new laws, rules, and regulations, such as those relating to organizational conflicts of interest issues or limits;

• risks related to completed and future acquisitions, including our ability to realize the expected benefits from such acquisitions;

• an inability to anticipate or estimate the tax implications of changes in tax law, or utilize existing or future tax benefits;

• variable purchasing patterns under U.S. government GSA schedules, blanket purchase agreements and indefinite delivery, indefinite quantity, or IDIQ, contracts;

In light of these risks, uncertainties and other factors, the forward-looking statements might not prove to be accurate and you should not place undue reliance upon them. All forward-looking statements speak only as of the date made and we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We established a Rabbi trust to provide for the payment of benefits under our non-qualified deferred compensation plan that became effective in the first quarter of fiscal 2019. As of September 30, 2018, fund assets totaled $3.2 million which include mutual fund investments that are subject to fluctuations in market prices and interest rates. Cash distributions made to plan participants are recognized as operating cash flows in the condensed consolidated statement of cash flows and have the effect of lowering both fund assets and the corresponding fund liabilities on a one-for-one basis. Changes in fair value on fund liabilities offset the changes in fair value of fund assets, and changes in fair value on both fund assets and fund liabilities are recognized in earnings on our condensed consolidated statements of operations. See Notes 12 and 16 to our condensed consolidated financial statements for further discussion.

With the exception of the Rabbi trust discussed above, there have been no material changes during the period covered by this Quarterly Report on Form 10-Q to the information disclosed in the Quantitative and Qualitative Disclosures About Market Risk section in Part II, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended March 31, 2018 filed with the Securities and Exchange Commission on May 29, 2018.

Item 4.    Controls and Procedures

Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q, or Quarterly Report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

44

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Our performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws and regulations are subject to continuous audit, review, and investigation by the U.S. government which may include such investigative techniques as subpoenas or civil investigative demands. Given the nature of our business, these audits, reviews, and investigations may focus, among other areas, on various aspects of procurement integrity, labor time reporting, sensitive and/or classified information access and control, executive compensation, and post government employment restrictions. We are not always aware of our status in such matters, but we are currently aware of certain pending audits and investigations involving labor time reporting, procurement integrity, and classified information access. In addition, from time to time, we are also involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, we do not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on our financial condition and results of operations. As of September 30, 2018 and March 31, 2018, there were no material amounts accrued in the condensed consolidated financial statements related to these proceedings.

Six former officers and stockholders who had departed the Company prior to the acquisition of the Company by the Carlyle Group (the "Carlyle Acquisition") have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009, against us and certain of our current and former directors and officers. Three of these suits were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010. Another two of the original nine suits were consolidated into one complaint on September 24, 2014. Each of the suits arises out of the Carlyle Acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Some of the suits also allege that the acquisition price paid to stockholders was insufficient. The various suits assert claims for breach of contract, tortious interference with contract, breach of fiduciary duty, civil Racketeer Influenced and Corrupt Organizations Act, or RICO, violations, violations of ERISA, and/or securities and common law fraud. Three of these suits have been dismissed with all appeals exhausted. The two suits that were consolidated into one action on September 24, 2014 were settled on April 16, 2015. One of the remaining suits has been dismissed by the United States District Court for the Southern District of California and such dismissal was upheld by the United States Court of Appeals for the Ninth Circuit. The plaintiff in this suit subsequently filed a Petition for Writ of Certiorari to the United States Supreme Court, which was denied by the United States Supreme Court on January 9, 2017. The other three remaining suits that were previously consolidated on September 7, 2010 have been dismissed by the United States District Court for the Southern District of New York and were on appeal before the United States Court of Appeals for the Second Circuit. On July 13, 2017, the United States Court of Appeals for the Second Circuit affirmed the ruling of the United States District Court for the Southern District of New York, except for one plaintiff’s securities fraud claim, which was remanded to the United States District Court for the Southern District of New York to give the plaintiff, Paul Kocourek leave to file another amended complaint to attempt to plead a securities fraud claim. On April 6, 2018, the plaintiff filed an amended complaint in which Mr. Kocourek, individually, as Trustee of the Paul Kocourek Trust and on behalf of a putative class, alleges that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Exchange Act. On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint. A lead plaintiff has not been appointed. On August 2, 2018, the defendants filed a motion to dismiss the amended complaint. On September 17, 2018, the plaintiff filed an opposition to the defendants’ motion to dismiss the amended complaint. The defendants filed their reply to plaintiff's opposition on October 17, 2018.

As of September 30, 2018, the aggregate alleged damages that will be sought in the remaining suit is unknown. As of September 30, 2018, although the outcome of any of these cases is inherently uncertain and may be materially adverse, based on current information, we do not expect them to have a material adverse effect on our financial condition and results of operations. 

On June 7, 2017, Booz Allen Hamilton was informed that the U.S. Department of Justice (DOJ) is conducting a civil and criminal investigation of the Company. In connection with the investigation, the DOJ has requested information from the Company relating to certain elements of the Company’s cost accounting and indirect cost charging practices with the U.S. government. Since learning of the investigation, the Company has engaged a law firm experienced in these matters to represent the Company in connection with this matter and respond to the government's requests. As is commonly the case with this type of matter, the Company has also been in contact with other regulatory agencies and bodies, including the SEC, which notified the Company that it is conducting an investigation that the Company believes relates to the matters that are also the subject of

45

the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are the subject of the DOJ's investigation. In accordance with the Company's practice, the Company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. At this stage, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with these matters.

On June 19, 2017, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Virginia styled Langley v. Booz Allen Hamilton Holding Corp., No. 17-cv-00696 naming the Company, its Chief Executive Officer and its Chief Financial Officer as defendants purportedly on behalf of all purchasers of the Company’s securities from May 19, 2016 through June 15, 2017. On September 5, 2017, the court named two lead plaintiffs and on October 20, 2017, the lead plaintiffs filed a consolidated amended complaint. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, alleging misrepresentations or omissions by the Company purporting to relate to matters that are the subject of the DOJ investigation described above. The plaintiffs seek to recover from the Company and the individual defendants an unspecified amount of damages. The Company believes the suit lacks merit and intends to defend against the lawsuit. Motions to dismiss were argued on January 12, 2018 and on February 8, 2018, the court dismissed the amended complaint in its entirety without prejudice. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On November 13, 2017, a Verified Shareholder Derivative Complaint was filed in the United States District Court for the District of Delaware styled Celine Thum v. Rozanski et al., C.A. No. 17-cv-01638, naming the Company as a nominal defendant and numerous current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, abuse of control, gross mismanagement, and violations of Sections 14(a), 10(b) and 20(a) of the Exchange Act, as amended, purportedly relating to matters that are the subject of the DOJ investigation described above. The parties have stipulated to a stay of the proceedings pending the outcome of the securities litigation (described above), which the court ordered on January 24, 2018. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

Item 1A. Risk Factors

There have been no material changes during the period covered by this Quarterly Report on Form 10-Q to the risk factors disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended March 31, 2018 filed with the Securities and Exchange Commission on May 29, 2018.

(1) On December 12, 2011, the Board of Directors approved a $30.0 million share repurchase program. On January 27, 2015, the Board of Directors approved an increase to our share repurchase authorization from $30.0 million to up to $180.0 million. On January 25, 2017, the Board of Directors approved an increase to our share repurchase authorization from $180.0 million to up to $410.0 million. On November 2, 2017, the Board of Directors approved an increase to our share repurchase authorization from $410.0 million to up to $610.0 million. On May 24, 2018, the Board of Directors approved an increase to our share repurchase authorization from $610.0 million to up to $910.0 million. A special committee of the Board of Directors was appointed to evaluate market conditions and other relevant factors and initiate repurchases under the program from time to time. The share repurchase program may be suspended, modified or discontinued at any time at the Company’s discretion without prior notice. See Note 14 to our

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission, or SEC, and should be read in conjunction with the information contained in the Company's Annual Report on Form 10-K for the year ended March 31, 2018. The interim period unaudited condensed consolidated financial statements are presented as described below. Certain information and disclosures normally required for annual financial statements have been condensed or omitted pursuant to GAAP and SEC rules and regulations. In the opinion of management, all adjustments considered necessary for fair presentation of the results of the interim period presented have been included. The Company’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The results of operations for the six months ended September 30, 2018 are not necessarily indicative of results to be expected for the full fiscal year.

The condensed consolidated financial statements and notes of the Company include its subsidiaries, and the joint ventures and partnerships over which the Company has a controlling financial interest. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies.

Effective April 1, 2018, the Company adopted Accounting Standards Codification (ASC) No. 606, Revenue from Contracts with Customers (Topic 606), and Accounting Standard Updates (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, on a full retrospective method for all amounts and percentages presented and disclosures set forth in this Form 10-Q.

Certain amounts reported in the Company's prior year condensed consolidated financial statements have been reclassified to conform to the current year presentation.

Accounting Estimates

The preparation of financial statements in conformity with GAAP requires 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 revenue and expenses during the reporting periods. Areas of the financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, certain deferred costs, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.

Recently Adopted Accounting Standards

The Company has accounted for the tax effects of the Tax Cuts and Jobs Act, or the 2017 Tax Act, under the guidance of Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, or SAB 118, on a provisional basis as of the fourth quarter of fiscal 2018. During the three months ended September 30, 2018, the Company continued its assessment of the 2017 Tax Act, including the potential accounting impact for any new guidance issued during the quarter. The Company made immaterial provisional adjustments associated with the limitation on the deductibility of certain executive compensation based on its preliminary assessment of the recently issued IRS Notice 2018-68. There were no additional changes to the provisional amounts recorded at March 31, 2018. The Company expects to complete its accounting assessment within the prescribed measurement period. See Note 10 to our consolidated financial statements for further information regarding the updated effects of the 2017 Tax Act during the second quarter of fiscal 2019.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Codification No. 606, Revenue from Contracts with Customers (Topic 606). Topic 606, as amended, replaced existing revenue recognition standards by outlining a single set of comprehensive principles for recognizing revenue. The revenue standard also significantly expanded the disclosure requirements for revenue arrangements. Amendments to Topic 606 have generally focused on promoting a more consistent interpretation and application of the principles for recognizing revenue.

Topic 606 was effective for the Company beginning on April 1, 2018 (i.e., beginning with the first quarter fiscal 2019 interim financial statements). The Company adopted the new revenue standard using the full retrospective transition method, which requires that it be applied to each prior reporting period presented and that the cumulative effect of applying the standard be recognized at the earliest period presented (i.e., April 1, 2016, the beginning of the first quarter of fiscal 2017). During fiscal 2018, the Company completed its assessment of the cumulative effect of adopting Topic 606 and assessed the impact to be immaterial as of the date of adoption. The cumulative impact on our retained earnings for the earliest period presented of April 1, 2016 was an increase of $2.9 million. Thereafter, the adoption of Topic 606 increased our fiscal 2017 retained earnings by $8.4 million and decreased our fiscal 2018 retained earnings by $3.4 million, resulting in a cumulative impact on our retained earnings of $7.9 million as of April 1, 2018. The impact of Topic 606 on fiscal 2017 and 2018 results may not be representative of the impact on subsequent years’ results.

For more information on the notable impacts of the adoption of Topic 606 on the Company's accounting policies, practices, estimates, and significant judgments, refer to the Company's Annual Report on Form 10-K for the year ended March 31, 2018 and Note 3, Revenue Recognition.

The Company also retrospectively adopted ASU 2017-07, which changed the presentation of net periodic benefit cost components on the condensed consolidated statement of operations. Under this guidance, the service cost component of net periodic benefit cost continues to be presented consistent with other employee compensation costs and within operating income, while the remaining components of net periodic benefit costs are excluded from operating income. As a result, $1.9 million and $3.8 million of net periodic benefit costs related to non-service components, for the three and six months ended September 30, 2017 respectively, were reclassified to Other income (expense), net in the condensed consolidated statement of operations in the second quarter of fiscal 2018.

The Company's previously issued condensed consolidated financial statements have been adjusted for the retrospective adoption of both Topic 606 and ASU 2017-07, as summarized in the following table:

Recent Accounting Pronouncements Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance requires a customer in a cloud computing arrangement that is a service contract to follow existing internal-use software guidance to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with that of implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 is effective for interim reporting periods for fiscal years beginning after December 15, 2019. Early adoption is permitted. The standard may be adopted either retrospectively or prospectively. The Company is currently assessing the future impact of this update on its consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, the guidance also expands an entity's ability to apply hedge accounting for nonfinancial and financial risk components, simplifies the hedge documentation and hedge effectiveness assessment requirements, and modifies certain disclosure requirements. ASU 2017-12 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability of accounting for lease transactions. The new leasing standard requires lessees to recognize lease assets and lease liabilities on their balance sheet for all leases with a lease term of greater than 12 months. Lessor accounting is largely unchanged. Topic 842 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB provided an alternative transition method of adoption through ASU No. 2018-11, Targeted Improvements, which permits the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company intends to adopt the standard beginning in fiscal 2020 using the modified retrospective transition approach, specifically, using the alternative transition method provided by ASU 2018-11.

A dedicated implementation team has been established that continues to make progress toward completing the evaluation of the impact of the new standard. The Company's assessment efforts to date have included reviewing the provisions of Topic 842, gathering information to evaluate its lease population and portfolio, evaluating the nature of real and personal property and other arrangements that may meet the definition of a lease, designing and implementing one-time implementation controls as well as new post-adoption lease processes and controls, implementing a new lease accounting software solution, and evaluating certain accounting policy elections. The Company anticipates finalizing its accounting policy, accounting software, systems and process modifications during the fourth quarter of fiscal 2019.

Based on a preliminary assessment, the Company does not expect there to be a significant change in determining what constitutes a lease, however, the Company expects that virtually all of its operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in a significant increase in the assets and liabilities on its consolidated balance sheets. The pattern of recognition for operating leases within the consolidated statements of operations and comprehensive income is not anticipated to significantly change. The adoption is not expected to impact the Company’s ability to comply with financial covenants as defined within the Company's Sixth Amendment to its Credit Agreement dated July 23, 2018, as discussed further in Note 8, Debt. The Company is continuing to refine its process for quantifying the financial statement impacts and anticipates finalizing its assessment of the materiality of adopting Topic 842 in conjunction with reporting its results for the third quarter of fiscal 2019.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The amendments set forth certain presentation requirements, including that such analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed with all significant reconciling items described by appropriate captions with contributions from and distributions to owners shown separately. This final rule is effective 30 days after publication in the Federal Register and will generally be effective for the Company for the third quarter of fiscal year 2019. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

Other accounting and reporting pronouncements issued after September 30, 2018 and through the filing date are not expected to have a material impact on the Company's condensed consolidated financial statements.

Revenue from Contract with Customer [Abstract]

Revenue

REVENUE

Revenue Recognition

The Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, and cyber services, substantially with the U.S. government and its agencies and, to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable-plus-fee contracts, time-and-materials contracts, and fixed-price contracts.

The Company considers a contract with a customer to exist under Topic 606 when there is approval and commitment from both the Company and the customer, the rights of the parties and payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. The Company also will consider whether two or more contracts entered into with the same customer should be combined and accounted for as a single contract. Furthermore, in certain transactions with commercial clients and with the U.S. government, the Company may commence providing services prior to receiving a formal approval from the customer. In these situations, the Company will consider the factors noted above, the risks associated with commencing the work and legal enforceability in determining whether a contract with the customer exists under Topic 606.

Customer contracts are often modified to change the scope, price, specifications or other terms within the existing arrangement. Contract modifications are evaluated by management to determine whether the modification should be accounted for as part of the original performance obligation(s) or as a separate contract. If the modification adds distinct goods or services and increases the contract value proportionate to the stand-alone selling price of the additional goods or services, it will be accounted for as a separate contract. Generally, the Company’s contract modifications do not include goods or services which are distinct, and therefore are accounted for as part of the original performance obligation(s) with any impact on transaction price or estimated costs at completion being recorded as through a cumulative catch-up adjustment to revenue.

The Company evaluates each service deliverable contracted with the customer to determine whether they represent promises to transfer distinct goods or services. Under Topic 606, these are referred to as performance obligations. One or more service deliverables often represent a single performance obligation. This evaluation requires significant judgment and the impact of combining or separating performance obligations may change the time over which revenue from the contract is recognized. The Company’s contracts generally provide a set of integrated or highly interrelated tasks or services and are therefore accounted for as a single performance obligation. However, in cases where we provide more than one distinct good or service within a customer contract, the contract is separated into individual performance obligations which are accounted for discretely.

Contracts with the U.S. government are subject to the Federal Acquisition Regulation ("FAR") and are priced based on estimated or actual costs of providing the goods or services. The Company derives a majority of its revenue from contracts awarded through a competitive bidding process. Pricing for non-U.S. government agencies and commercial customers is based on discrete negotiations with each customer. Certain of the Company’s contracts contain award fees, incentive fees or other provisions that may increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. Management estimates variable consideration as the most likely amount that we expect to achieve based on our assessment of the variable fee provisions within the contract, prior experience with similar contracts or clients, and management’s evaluation of the performance on such contracts. The Company may perform work under a contract that has not been fully funded if the work has been authorized by the management and the customer to proceed. The Company evaluates unfunded amounts as variable consideration in estimating the transaction price. We include the estimated variable consideration in our transaction price to the extent that it is probable that a significant reversal of revenue will not occur upon the ultimate settlement of the variable fee provision. In the limited number of situations where our contracts with customers contain more than one performance obligation, the Company allocates the transaction price of a contract between the performance obligations in the proportion to their respective stand-alone selling prices. The Company generally estimates the stand-alone selling price of performance obligations based on an expected cost-plus margin approach as allowed under Topic 606. Our U.S. government contracts generally contain FAR provisions that enable the customer to terminate a contract for default or for the convenience of the U.S. government.

The Company recognizes revenue for each performance obligation identified within our customer contracts when, or as, the performance obligation is satisfied by transferring the promised goods or services. Revenue may either be recognized over time, or at a point in time. The Company generally recognizes revenue over time as our contracts typically involve a continuous transfer of control to the customer. A continuous transfer of control under contracts with the U.S. government and its agencies is evidenced by clauses which require the Company to be paid for costs incurred plus a reasonable margin in the event that the customer unilaterally terminates the contract for convenience. For contracts where the Company recognizes revenue over time, a contract cost-based input method is generally used to measure progress towards satisfaction of the underlying performance obligation(s). Contract costs include direct costs such as materials, labor and subcontract costs, as well as indirect costs identifiable with, or allocable to, a specific contract that are expensed as incurred. The Company does not incur material incremental costs to acquire or fulfill contracts. Under a contract cost-based input method, revenue is recognized based on the proportion of contract costs incurred to the total estimated costs expected to be incurred upon completion of the underlying performance obligation. The Company includes both funded and unfunded portions of customer contracts in this estimation process.

For interim financial reporting periods, contract revenue attributable to indirect costs is recognized based upon agreed-upon annual forward-pricing rates established with the U.S. government at the start of each fiscal year. Forward pricing rates are estimated and agreed upon between the Company and the U.S. government and represent indirect contract costs required to execute and administer contract obligations. The impact of any agreed-upon changes, or changes in the estimated annual forward-pricing rates, will be recorded in the interim financial reporting period when such changes are identified. This change relates to the interim financial reporting period differences between the actual indirect cost incurred and allocated to customer contracts compared to the estimated amounts allocated to contracts using the estimated annual forward-pricing rates established with the U.S. government.

On certain contracts, principally time-and-materials and cost-reimbursable-plus-fee contracts, revenue is recognized using the right-to-invoice practical expedient as the Company is contractually able to invoice the customer based on the control transferred. However, we did not elect to use the practical expedient which would allow the Company to exclude contracts recognized using the right-to-invoice practical expedient from the remaining performance obligations disclosed below. Additionally, for stand-ready performance obligations to provide services under fixed-price contracts, revenue is recognized over time using a straight-line measure of progress as the control of the services is provided to the customer ratably over the term of the contract. If a contract does not meet the criteria for recognition of revenue over time, we recognize revenue at the point in time when control of the good or service is transferred to the customer. Determining a measure of progress towards the satisfaction of performance obligations requires management to make judgments that may affect the timing of revenue recognition.

In addition to the right-to-invoice practical expedient discussed above, the Company applied certain other practical expedients permitted by Topic 606, which include: a) using the portfolio approach where contracts with similar characteristics were assessed collectively to evaluate risk of being impacted by the adoption of Topic 606; b) applying the practical expedient allowing the Company to not restate completed contracts which began and ended in the same fiscal year prior to the date of the initial adoption; and c) electing to omit the disclosure related to remaining performance obligations for reporting periods presented before the date of the initial adoption.

Contract Estimates

Many of our contracts recognize revenue under a contract cost-based input method and require an Estimate-at-Completion (EAC) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at completion of performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For the three and six months periods ended September 30, 2018 and 2017, respectively, the aggregate impact of adjustments in contract estimates was not material.

Performance Obligations

Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations do not include negotiated but unexercised options.

As of September 30, 2018, the Company had $7.8 billion of remaining performance obligations and we expect to recognize more than half of the remaining performance obligations as revenue over the next 12 months, and approximately three quarters over the next 24 months. The remainder is expected to be recognized thereafter.

Disaggregation of Revenue

We disaggregate our revenue from contracts with customers by contract type, customer, as well as whether the Company acts as prime contractor or sub-contractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following series of tables presents our revenue disaggregated by these categories.

Revenue by Contract Type:

We generate revenue under the following three basic types of contracts:

• Cost-Reimbursable Contracts: Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee.

• Time-and-Materials Contracts: Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates.

• Fixed-Price Contracts: Under a fixed-price contract, we agree to perform the specified work for a predetermined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss.

The table below presents the total revenue for each type of contract:

	Three Months Ended September 30,								Six Months Ended September 30,

Contract Balances

Contract assets primarily consist of unbilled receivables typically resulting from revenue recognized exceeding the amount billed to the customer and right to payment is not just subject to the passage of time. Contract liabilities primarily consist of advance payments, billings in excess of costs incurred and deferred revenue. Contract assets and liabilities are reported on a net contract basis at the end of each reporting period. The Company maintains an allowance for doubtful accounts to provide for an estimate of uncollected receivables. Refer to Note 5 for more information on receivables recognized from contracts accounted for under Topic 606.

The following table summarizes the contract balances recognized on the Company’s condensed consolidated balance sheets:

	September 30, 2018		March 31, 2018
Contract assets:
Current	$	749,672	$	738,646
Long-term	60,093		59,633
Total	$	809,765	$	798,279
Contract liabilities:
Advance payments, billings in excess of costs incurred and deferred revenue	$	22,165	$	27,522

Changes in contract assets and contract liabilities are primarily due to the timing difference between the Company’s performance of services and payments from customers. For the three months ended September 30, 2018 and 2017, we recognized revenue of $3.8 million and $0.8 million and for the six months ended September 30, 2018 and 2017, we recognized revenue of $10.6 million and $6.6 million related to our contract liabilities on April 1, 2018 and 2017, respectively. To determine revenue recognized from contract liabilities during the reporting periods, the Company allocates revenue to individual contract liability balances and applies revenue recognized during the reporting periods first to the beginning balances of contract liabilities until the revenue exceeds the balances.

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

The Company computes basic and diluted earnings per share amounts based on net income for the periods presented. The Company uses the weighted-average number of common shares outstanding during the period to calculate basic earnings per share, or EPS. Diluted EPS adjusts the weighted average number of shares outstanding to include the dilutive effect of outstanding common stock options and other stock-based awards.

The Company currently has outstanding shares of Class A Common Stock. Unvested Class A Restricted Common Stock holders are entitled to participate in non-forfeitable dividends or other distributions. These unvested restricted shares participated in the Company's dividends declared and were paid in the first and second quarters of fiscal 2019 and 2018. As such, EPS is calculated using the two-class method whereby earnings are reduced by distributed earnings as well as any available undistributed earnings allocable to holders of unvested restricted shares. A reconciliation of the income used to compute basic and diluted EPS for the periods presented are as follows:

	Three Months Ended September 30,				Six Months Ended September 30,
	2018		2017		2018		2017
Earnings for basic computations (1)	$	92,127	$	72,966	$	195,681	$	142,974
Weighted-average common shares outstanding for basic computations	142,443,058		147,085,314		142,861,491		147,400,153
Earnings for diluted computations (1)	$	92,130	$	72,971	$	195,690	$	142,986
Dilutive stock options and restricted stock	1,265,851		1,802,183		1,353,582		1,976,722
Weighted-average common shares outstanding for diluted computations	143,708,909		148,887,497		144,215,073		149,376,875
Earnings per common share
Basic	$	0.65	$	0.50	$	1.37	$	0.97
Diluted	$	0.64	$	0.49	$	1.36	$	0.96

(1) During the three months ended September 30, 2018 and 2017, approximately 0.9 million and 1.4 million participating securities, respectively, were paid dividends totaling $0.2 million in both periods. During the six months ended September 30, 2018 and 2017, approximately 0.9 million and 1.4 million participating securities, respectively, were paid dividends totaling $0.3 million and $0.4 million, respectively. For the three months ended September 30, 2018 and 2017, there were undistributed earnings of $0.4 million and $0.4 million, respectively, allocated to the participating class of securities in both basic and diluted EPS. For the six months ended September 30, 2018 and 2017, there were undistributed earnings of $0.9 million and $0.9 million, respectively, allocated to the participating class of securities in both basic and diluted EPS. The allocated undistributed earnings and the dividends paid comprise the difference between net income presented on the condensed consolidated statements of operations and earnings for basic and diluted computations for the three and six months ended September 30, 2018 and 2017.

The EPS calculation for the three months ended September 30, 2018 and 2017 excludes 0.2 million and 0.4 million options, respectively, as their impact was anti-dilutive. The EPS calculation for the six months ended September 30, 2018 and 2017 excludes 0.2 million and 0.3 million options, respectively, as their impact was anti-dilutive.

Other long-term assets
Accounts receivable–unbilled	60,093			59,633
Total accounts receivable, net	$	1,225,419		$	1,193,338

Unbilled amounts represent revenues for which billings have not been presented to customers at quarter-end or year-end. These amounts are usually billed and collected within one year. Long-term unbilled receivables not anticipated to be billed and collected within one year, which are primarily related to retainage, holdbacks, and long-term rate settlements to be billed at contract closeout, are included in other long-term assets in the accompanying condensed consolidated balance sheets. The Company recognized a provision for doubtful accounts (including certain unbilled reserves) of $10.6 million and $2.2 million for the three months ended September 30, 2018 and 2017, respectively and $10.7 million and $3.1 million for the six months ended September 30, 2018 and 2017.

The primary financial instruments, other than derivatives, that potentially subject the Company to concentrations of credit risk are accounts receivable. The Company's primary customers are U.S. federal government agencies and prime contractors under contracts with the U.S. government. The Company continuously reviews its accounts receivable and records provisions for doubtful accounts as needed.

Term Loans and Revolving Credit Facility

On July 23, 2018 (the "Amendment Effective Date"), Booz Allen Hamilton Inc. ("Booz Allen Hamilton") and Booz Allen Hamilton Investor Corporation ("Investor"), and certain wholly-owned subsidiaries of Booz Allen Hamilton, entered into the Sixth Amendment (the "Sixth Amendment") to the Credit Agreement (as amended, the "Credit Agreement"), dated as of July 31, 2012 among Booz Allen Hamilton, Investor, certain wholly-owned subsidiaries of Booz Allen Hamilton and Bank of America, N.A., as Administrative Agent, and Collateral Agent and the other lenders and financial institutions from time to time party thereto (as previously amended by the First Amendment to the Credit Agreement, dated as of August 16, 2013, the Second Amendment to Credit Agreement, dated as of May 7, 2014, the Third Amendment to the Credit Agreement, dated as of July 13, 2016, the Fourth Amendment to the Credit Agreement, dated as of February 6, 2017, and the Fifth Amendment to the Credit Agreement, dated as of March 7, 2018). The Sixth Amendment provides for a new delayed draw (the "Delayed Draw Facility") on the tranche A term loan ("Term Loan A") facility in the amount of up to $400.0 million and extended the maturity of the Term Loan A and the revolving credit facility (the "Revolving Credit Facility") to July 2023. Additionally, the Sixth Amendment reduced the interest rate spread applicable to the Term Loan A and the Revolving Credit Facility from a range of 1.50% to 2.25% to a range of 1.25% to 2.00% based on consolidated net total leverage. The interest rate applicable to the Term Loan B ("Term Loan B" and, together with Term Loan A, the "Term Loans") remained unchanged.

Prior to the Sixth Amendment, approximately $1,079.5 million was outstanding under Term Loan A. Pursuant to the Sixth Amendment, certain lenders converted their existing Term Loan A loans into a new tranche of Term Loan A loans in an aggregate amount, along with Term Loan A loans advanced by certain new lenders, of approximately $1,479.5 million, $400.0 million of which will be available as the Delayed Draw Facility. The Delayed Draw Facility is accessible for nine months from the Amendment Effective Date (the "Delayed Draw Availability Period"). The Company is able to draw on the Delayed Draw Facility on up to two occasions during the Delayed Draw Availability Period in an amount per draw (x) of not less than $100.0 million per draw or (y) equal to the amount of unused commitments in respect of the Delayed Draw Facility remaining at the time of such borrowing. The proceeds from the new lenders were used to prepay in full all of the existing Term Loan A that was not converted into the new Term Loan A tranche. The proceeds of the Delayed Draw Facility will be used for general corporate purposes and other purposes not prohibited by the Credit Agreement.

Prior to the Sixth Amendment, $500.0 million was available under the revolving credit facility. Pursuant to the Sixth Amendment, certain lenders under the Existing Credit Agreement converted their Existing Revolving Commitments into a new tranche of revolving commitments (the "New Revolving Commitments" and the revolving credit loans made thereunder, the "New Revolving Loans") in an aggregate amount, along with New Revolving Commitments of certain new lenders, of $500.0 million.

As of September 30, 2018, the Credit Agreement provided Booz Allen Hamilton with a $1,064.7 million Term Loan A, $400.0 million Delayed Draw Facility, a $393.0 million Term Loan B, and $500.0 million in New Revolving Commitments with a sub-limit for letters of credit of $100.0 million. As of September 30, 2018, the maturity date of Term Loan A and the termination date for the Revolving Credit Facility was July 23, 2023 and the maturity date of Term Loan B was June 30, 2023. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Investor, and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. Subject to specified conditions, without the consent of the then-existing lenders (but subject to the receipt of commitments), the Term Loans or New Revolving Credit Facility may be expanded (or a new term loan facility or revolving credit facility added to the existing facilities) by up to (i) greater of (x) $627 million and (y) 100% of consolidated EBITDA of Booz Allen Hamilton, as of the end of the most recently ended four quarter period for which financial statements have been delivered pursuant to the Credit Agreement plus (ii) the aggregate principal amount under which pro forma consolidated net secured leverage remains less than or equal to 3.50:1.00.

At Booz Allen Hamilton’s option, borrowings under the Secured Credit Facility bear interest based either on LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or a base rate (equal to the highest of (x) the administrative agent’s prime corporate rate, (y) the overnight federal funds rate plus 0.50%, and (z) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. The applicable margin for Term Loan B is 2.00% for LIBOR loans and 1.00% for base rate loans. Unused commitments under the Revolving Credit Facility are subject to a quarterly fee ranging from 0.20% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio.

Booz Allen Hamilton occasionally borrows under the Revolving Credit Facility in anticipation of cash demands. During the first and second quarters of fiscal 2019, Booz Allen Hamilton accessed a total of $70.0 million of the $500.0 million New Revolving Commitments. As of September 30, 2018 and March 31, 2018, there were no amounts outstanding under the Revolving Credit Facility.

The Credit Agreement requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity, and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include limitations on the following, in each case subject to certain exceptions: (i) indebtedness and liens, (ii) mergers, consolidations or amalgamations, liquidations, wind-ups or dissolutions, and disposition of all or substantially all assets; (iii) dispositions of property; (iv) restricted payments; (v) investments; (vi) transactions with affiliates; (vii) change in fiscal periods; (viii) negative pledges; (ix) restrictive agreements; (x) line of business; and (xi) speculative hedging. The events of default include the following, in each case subject to certain exceptions: (a) failure to make required payments under the Secured Credit Facility; (b) material breaches of representations or warranties under the Secured Credit Facility; (c) failure to observe covenants or agreements under the Secured Credit Facility; (d) failure to pay or default under certain other material indebtedness; (e) bankruptcy or insolvency; (f) certain Employee Retirement Income Security Act, or ERISA events; (g) certain material judgments; (h) actual or asserted invalidity of the Guarantee and Collateral Agreements or the other security documents or failure of the guarantees or perfected liens thereunder; and (i) a change of control. In addition, Booz Allen Hamilton is required to meet certain financial covenants at each quarter end, namely Consolidated Net Total Leverage and Consolidated Net Interest Coverage Ratios. As of September 30, 2018 and March 31, 2018, Booz Allen Hamilton was in compliance with all financial covenants associated with its debt and debt-like instruments.

Senior Notes

On April 25, 2017, Booz Allen Hamilton issued $350 million aggregate principal amount of its 5.125% Senior Notes (the "Senior Notes"), under an Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the "Subsidiary Guarantors"), and Wilmington Trust, National Association, as trustee (the "Trustee"), as supplemented by the First Supplemental Indenture, dated as of April 25, 2017, among Booz Allen Hamilton, the Subsidiary Guarantors and the Trustee. Each of Booz Allen Hamilton's existing and future domestic restricted subsidiaries that guarantee its obligations under the Secured Credit Facility and certain other indebtedness will guarantee the Senior Notes on a senior unsecured basis. Interest is payable semi-annually on May 1 and November 1 of each year, beginning on November 1, 2017, and principal is due at maturity on May 1, 2025. In connection with the Senior Notes, the Company recognized $6.7 million of issuance costs, which were recorded as an offset against the carrying value of debt and will be amortized to interest expense over the term of the Senior Notes. During the first and second quarters of fiscal 2019, interest payments of $9.0 million were made for the Senior Notes.

Borrowings under the Term Loans and, if used, the Revolving Credit Facility, incur interest at a variable rate. In accordance with Booz Allen Hamilton’s risk management strategy, between April 6, 2017 and May 24, 2017, Booz Allen Hamilton executed a series of interest rate swaps. As of September 30, 2018, Booz Allen Hamilton had interest rate swaps with an aggregate notional amount of $450 million. These instruments hedge the variability of cash outflows for interest payments on the floating portion of the term loan debt. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (See Note 9 in our condensed consolidated financial statements).

Interest on debt and debt-like instruments consisted of the following:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

DERIVATIVES

The Company utilizes derivative financial instruments to manage interest rate risk related to its variable rate debt. The Company’s objectives in using these interest rate derivatives, which were designated as cash flow hedges, are to manage its exposure to interest rate movements and reduce volatility to interest expense. During the first quarter of fiscal 2018, the Company entered into several forward starting floating-to-fixed interest rate swap agreements with multiple financial institutions with a start date of April 30, 2018. The aggregate notional amount of these interest rate swap agreements was $450 million as of September 30, 2018. The swaps have staggered maturities, ranging from June 30, 2021 to June 30, 2022. These swaps mature within the last tranche of the Company's floating rate debt (June 30, 2023).

The floating-to-fixed interest rate swaps involve the exchange of variable interest amounts from a counterparty for the Company making fixed-rate interest payments over the life of the agreements without exchange of the underlying notional amount and effectively converting a portion of the variable rate debt into fixed interest rate debt.

Derivative instruments are recorded in the condensed consolidated balance sheet on a gross basis at estimated fair value. As of September 30, 2018, $2.8 million and $9.1 million were classified as other current assets and other long-term assets, respectively, on the condensed consolidated balance sheet. As of March 31, 2018, $0.7 million and $7.2 million were classified as other current assets and other long-term assets, respectively, on the condensed consolidated balance sheet.

For interest rate swaps designated as cash flow hedges, the changes in the fair value of derivatives is recorded in Accumulated Other Comprehensive Income, or AOCI, net of taxes, and is subsequently reclassified into interest expense in the period that the hedged forecasted interest payments are made on the Company's variable-rate debt. For the three and six months ended September 30, 2018, a $1.2 million and $3.0 million gain, respectively, was recognized in AOCI, and $0.1 million and $0.08 million was reclassified into interest expense. For the three and six months ended September 30, 2017, a $0.1 million and $0.6 million loss was recognized in AOCI, and there were no amounts reclassified into interest expense. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. As of September 30, 2018, there was no ineffectiveness recognized in earnings.

Over the next 12 months, the Company estimates that $2.8 million will be reclassified as a decrease to interest expense. Cash flows associated with periodic settlements of interest rate swaps will be classified as operating activities in the condensed consolidated statement of cash flows.

The Company is subject to counterparty risk in connection with its interest rate swap derivative contracts. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The Company mitigates this credit risk by entering into agreements with credit-worthy counterparties and regularly reviews its credit exposure and the creditworthiness of the counterparties.

Income Taxes

INCOME TAXES

The 2017 Tax Act was enacted on December 22, 2017. The 2017 Tax Act reduced the U.S. federal corporate tax rate from 35.0% to 21.0% effective January 1, 2018. At September 30, 2018, the Company's assessment for the following elements was not complete: (1) the acceleration of depreciation; and (2) the limitation on the deductibility of certain executive compensation. However, based on a preliminary assessment of the recently issued IRS Notice 2018-68, the Company recognized an additional measurement-period adjustment of $1.1 million relating to the deductibility of certain executive compensation, with a corresponding adjustment of $1.1 million to income tax expense during the quarter. The effect of the measurement-period adjustment on the three months ended September 30, 2018 effective tax rate was approximately 0.9%. The Company will continue to make and refine the calculations as additional analysis is completed and our estimates may be materially affected by additional clarifications and interpretations of the legislation. This includes the written consent the Company received from the IRS on October 19, 2018 in response to its application for a Change in Accounting Method filed on March 29, 2018. This method change is related to the Company’s recognition of revenue for income tax purposes associated with its unbilled receivables. Since this consent agreement was received subsequent to September 30, 2018, the financial statement effect related to a measurement-period adjustment of these changes will be recorded in the Company’s third quarter of fiscal 2019 pursuant to ASC 740. The Company will incorporate this method change in its fiscal 2018 federal and state income tax returns. As of September 30, 2018, the Company preliminarily estimates the measurement-period adjustment impact to fiscal 2019 from this method change to be approximately $28.9 million of a reduction to income tax expense.The Company expects to finalize its assessment of all provisional amounts within the allowed one-year measurement period provided for under SAB 118. Other than the executive compensation discussed above, the Company has not made any additional adjustments to fiscal 2018 provisional amounts during the six months ended September 30, 2018.

The Company’s effective income tax rates were 22.7% and 33.4% for the three months ended September 30, 2018 and 2017, respectively, and 23.5% and 33.6% for the six months ended September 30, 2018 and 2017, respectively. The decrease in the effective tax rate as compared to the same period last fiscal year was primarily due to the 2017 Tax Act's reduction of the U.S. federal corporate tax rate. The effective tax rates of 22.7% and 23.5% for the three and six months ended September 30, 2018 differ from the federal statutory rate of 21.0% primarily due to the inclusion of state income taxes and permanent rate differences, which are predominantly related to meals and entertainment and certain executive compensation, offset in the current three months by discrete tax items.

The Company is currently contesting tax assessments from the District of Columbia Office of Tax and Revenue for fiscal years 2013 through 2015 at various stages of applicable administrative and judicial processes, with a combined amount at issue of approximately $11.5 million, net of associated tax benefits as of September 30, 2018. The Company has taken similar tax positions with respect to subsequent fiscal years, totaling in aggregate $28.3 million. As of September 30, 2018, the Company does not maintain reserves for any uncertain tax positions related to the contested tax benefits, and, given the recoverable nature of the state tax expense, it does not believe the resolution of these matters will have a material adverse effect on its results of operations, cash flows or financial condition.

The Company continues to carry a reserve of $10.2 million for income tax uncertainties created with the business acquisition of eGov Holdings, Inc. (d/b/a Aquilent) in the fourth quarter of fiscal 2017 resulting from uncertainty in the sustainability of the acquiree's prior tax-return positions under examination with the relevant tax authorities.

EMPLOYEE BENEFIT PLANS

Defined Contribution Plan

The Company sponsors the Employees’ Capital Accumulation Plan, or ECAP, which is a qualified defined contribution plan that covers eligible U.S. and international employees. ECAP provides for distributions, subject to certain vesting provisions, to participants by reason of retirement, death, disability, or termination of employment. Effective April 1, 2014, the Company transitioned from a discretionary employer contribution to an annual matching contribution of up to 6% of eligible annual income as determined by the Internal Revenue Code for the ECAP.  Total expense recognized under ECAP was $33.6 million and $30.7 million for the three months ended September 30, 2018 and 2017, respectively, and $66.2 million and $61.8 million for the six months ended September 30, 2018 and 2017, respectively. The Company-paid contributions were $16.9 million and $15.5 million for the three months ended September 30, 2018 and 2017, respectively, and $34.4 million and $31.1 million for the six months ended September 30, 2018 and 2017, respectively.

Defined Benefit Plan and Other Postretirement Benefit Plans

The Company provides postretirement healthcare benefits to former officers under a medical indemnity insurance plan, with premiums paid by the Company. This plan is referred to as the Officer Medical Plan. The Company also established a non-qualified defined benefit plan for all officers in May 1995, or the Retired Officers' Bonus Plan, which pays a lump-sum amount of $10,000 per year of service as an officer, provided the officer meets retirement vesting requirements. In addition, the Company provides a fixed annual allowance after retirement to cover financial counseling and other expenses. The Retired Officers' Bonus Plan is not salary related, but rather is based primarily on years of service. During fiscal 2017, the Company adopted a new plan which will provide for a one-time, lump sum retirement payment of one month’s salary when a vice-president retires from the Company, effective April 1, 2017. This is referred to as the Retired Vice-President Bonus Plan. Additionally, the Company offers medical and dental benefits to inactive employees (and their eligible dependents) on long-term disability.

The components of net postretirement medical expense for the Officer Medical Plan were as follows:

	Three Months Ended September 30,				Six Months Ended September 30,
	2018		2017		2018		2017
Service cost	$	1,488	$	1,116	$	2,976	$	2,232
Interest cost	1,282		1,252		2,564		2,504
Net actuarial loss	527		568		1,054		1,135
Total postretirement medical expense	$	3,297	$	2,936	$	6,594	$	5,871

The service cost component of net periodic benefit cost is included in cost of revenue and general and administrative expenses, and the non-service cost components of net periodic benefit cost (interest cost and net actuarial loss) is included as part of other income (expense), net in the accompanying condensed consolidated statements of operations.

As of September 30, 2018 and March 31, 2018, the unfunded status of the post-retirement medical plan was $130.5 million and $126.9 million, respectively, which is included in other long-term liabilities in the accompanying condensed consolidated balance sheets.    

Deferred Compensation Plan

The Company established a non-qualified deferred compensation plan (the "Plan") for certain executives and other highly compensated employees that became effective in the current period. Pursuant to the Plan, participants are eligible to defer up to 100% of their incentive cash compensation on a tax deferred basis in excess of the IRS limits imposed on 401(k) plans. The assets of the plan are held in a consolidated trust and are subject to the claims of the Company's general creditors under federal and state laws in the event of insolvency. Consequently, the trust qualifies as a Rabbi trust for income tax purposes.

As of September 30, 2018, $3.2 million of plan investments and obligations were recorded in other long term assets and in other long term liabilities, respectively, in the condensed consolidated balance sheets, representing the fair value related to the deferred compensation plan. Adjustments to the fair value of the plan investments and obligations are recorded in operating expenses.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3).

A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The financial instruments measured at fair value in the accompanying condensed consolidated balance sheets consist of the following:

(1) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 9 for further discussion on the Company’s derivative instruments designated as cash flow hedges.

(2)Investments in this category consist primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our condensed consolidated balance sheets.

(3) The Company recognized a contingent consideration liability of $3.6 million in connection with its acquisition of Aquilent in fiscal 2017. As of September 30, 2018 and March 31, 2018, the estimated fair value of the contingent consideration liability was $3.3 million and $3.6 million, respectively, and was valued using probability-weighted cash flows, which is based on the use of Level 3 fair value measurement inputs. The liability is recorded in other long-term liabilities in the condensed consolidated balance sheet.

The fair value of the Company's cash and cash equivalents, which are primarily Level 1 inputs, approximated its carrying values at September 30, 2018 and March 31, 2018. The fair value of the Company's debt instruments approximated its carrying value at September 30, 2018 and March 31, 2018. The fair value of debt is determined using quoted prices or other market information obtained from recent trading activity of each debt tranche in markets that are not active (Level 2 inputs). The fair value is corroborated by prices derived from the interest rate spreads of recently completed leveraged loan transactions of a similar credit profile, industry, and terms to that of the Company. The fair value of the Senior Notes is determined using quoted prices or other market information obtained from recent trading activity in the high-yield bond market (Level 2 inputs).

COMMITMENTS AND CONTINGENCIES

Letters of Credit and Third-Party Guarantees

As of September 30, 2018 and March 31, 2018, the Company was contingently liable under open standby letters of credit and bank guarantees issued by our banks in favor of third parties that totaled $9.3 million and $6.3 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At September 30, 2018 and March 31, 2018, approximately $1.0 million and $1.4 million, respectively, of these instruments reduced the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $15.0 million facility established in fiscal 2015 of which $6.7 million and $10.1 million were available to the Company at September 30, 2018 and March 31, 2018, respectively.

Government Contracting Matters

For the three months ended September 30, 2018 and 2017, approximately 96% and 97% of the Company's revenue and for both the six months ended September 30, 2018 and 2017, approximately 97% of the Company's revenue was generated from contracts where the end user was an agency or department of the U.S. government, including contracts where the Company performed either as a prime contractor or subcontractor, and regardless of the geographic location in which the work was performed. U.S. government contracts and subcontracts are subject to extensive legal and regulatory requirements. From time to time and in the ordinary course of business, agencies of the U.S. government audit our contract costs and conduct inquiries and investigations of our business practices with respect to government contracts to determine whether the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government agencies, including the Defense Contract Audit Agency, routinely audit our contract costs, including allocated indirect costs for compliance with the Cost Accounting Standards and the Federal Acquisition Regulation. These agencies also conduct reviews and investigations and make inquiries regarding our accounting and other systems in connection with our performance and business practices with respect to our government contracts and subcontracts. U.S. government audits, inquiries, or investigations of the Company, whether related to the Company's U.S. government contracts or subcontracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including withholding of payments, suspension of payments, repayments, fines, or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting. Management believes it has recorded the appropriate provision for any audit, inquiry, or investigation of which it is aware. Management believes it has recorded the appropriate provision for the estimated losses that may be experienced from any such reductions and/or penalties. As of September 30, 2018 and March 31, 2018, the Company had recorded liabilities of approximately $179.9 million and $168.6 million, respectively, for its current best estimate of amounts to be refunded to customers for potential adjustments from audits or reviews of contract costs incurred subsequent to fiscal year 2011, and for contracts not yet closed that are impacted by settlement of audits or reviews of contract costs incurred in prior fiscal years.

Litigation

The Company is involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, management does not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on the Company’s financial condition and results of operations. As of September 30, 2018 and March 31, 2018, there were no material amounts accrued in the condensed consolidated financial statements related to these proceedings.

Six former officers and stockholders who had departed the Company prior to the acquisition of the Company by the Carlyle Group (the "Carlyle Acquisition") have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009, against us and certain of our current and former directors and officers. Three of these suits were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010. Another two of the original nine suits were consolidated into one complaint on September 24, 2014. Each of the suits arises out of the Carlyle Acquisition and alleges that the former stockholders are entitled to certain payments that they would have received if they had held their stock at the time of the Carlyle Acquisition. Some of the suits also allege that the acquisition price paid to stockholders was insufficient. The various suits assert claims for breach of contract, tortious interference with contract, breach of fiduciary duty, civil Racketeer Influenced and Corrupt Organizations Act, or RICO, violations, violations of the ERISA, and/or securities and common law fraud. Three of these suits have been dismissed with all appeals exhausted. The two suits that were consolidated into one action on September 24, 2014 were settled on April 16, 2015. One of the remaining suits has been dismissed by the United States District Court for the Southern District of California and such dismissal was upheld by the United States Court of Appeals for the Ninth Circuit. The plaintiff in this suit subsequently filed a Petition for Writ of Certiorari to the United States Supreme Court, which was denied by the United States Supreme Court on January 9, 2017. The other three remaining suits that were previously consolidated on September 7, 2010 have been dismissed by the United States District Court for the Southern District of New York and were on appeal before the United States Court of Appeals for the Second Circuit. On July 13, 2017, the United States Court of Appeals for the Second Circuit affirmed the ruling of the United States District Court for the Southern District of New York, except for one plaintiff’s securities fraud claim, which was remanded to the United States District Court for the Southern District of New York to give the plaintiff, Paul Kocourek, leave to file another amended complaint to attempt to plead a securities fraud claim. On April 6, 2018, the plaintiff filed an amended complaint in which Mr. Kocourek, individually, as Trustee of the Paul Kocourek Trust and on behalf of a putative class, alleges that the Company and certain former officers and directors violated Sections 10(b), 20(a) and 14(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). On April 25, 2018, the court entered an order postponing the deadline within which the defendants must answer or move to dismiss the amended complaint. A lead plaintiff has not been appointed. On August 2, 2018, the defendants filed a motion to dismiss the amended complaint. On September 17, 2018, the plaintiff filed an opposition to the defendants’ motion to dismiss the amended complaint. The defendants filed their reply to plaintiff's opposition on October 17, 2018.

As of September 30, 2018, the aggregate alleged damages that will be sought in the remaining suit is unknown. As of September 30, 2018, although the outcome of any of these cases is inherently uncertain and may be materially adverse, based on current information, management does not expect them to have a material adverse effect on our financial condition and results of operations.

On June 7, 2017, Booz Allen Hamilton was informed that the U.S. Department of Justice (DOJ) is conducting a civil and criminal investigation of the Company. In connection with the investigation, the DOJ has requested information from the Company relating to certain elements of the Company’s cost accounting and indirect cost charging practices with the U.S. government. Since learning of the investigation, the Company has engaged a law firm experienced in these matters to represent the Company in connection with this matter and respond to the government's requests. As is commonly the case with this type of matter, the Company has also been in contact with other regulatory agencies and bodies, including the Securities and Exchange Commission, which notified the Company that it is conducting an investigation that the Company believes relates to the matters that are also the subject of the DOJ's investigation. The Company may receive additional regulatory or governmental inquiries related to the matters that are the subject of the DOJ's investigation. In accordance with the Company's practice, the Company is cooperating with all relevant government parties. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. At this stage, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with these matters.

On June 19, 2017, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Virginia styled Langley v. Booz Allen Hamilton Holding Corp., No. 17-cv-00696 naming the Company, its Chief Executive Officer and its Chief Financial Officer as defendants purportedly on behalf of all purchasers of the Company’s securities from May 19, 2016 through June 15, 2017. On September 5, 2017, the court named two lead plaintiffs, and on October 20, 2017, the lead plaintiffs filed a consolidated amended complaint. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, alleging misrepresentations or omissions by the Company purporting to relate to matters that are the subject of the DOJ investigation described above. The plaintiffs seek to recover from the Company and the individual defendants an unspecified amount of damages. The Company believes the suit lacks merit and intends to defend against the lawsuit. Motions to dismiss were argued on January 12, 2018, and on February 8, 2018, the court dismissed the amended complaint in its entirety without prejudice. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

On November 13, 2017, a Verified Shareholder Derivative Complaint was filed in the United States District Court for the District of Delaware styled Celine Thum v. Rozanski et. al., C.A. No. 17-cv-01638, naming the Company as a nominal defendant and numerous current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, abuse of control, gross mismanagement, and violations of Sections 14(a), 10(b) and 20(a) of the Exchange Act, purportedly relating to matters that are the subject of the DOJ investigation described above. The parties have stipulated to a stay of the proceedings pending the outcome of the securities litigation (described above), which the court ordered on January 24, 2018. At this stage of the lawsuit, the Company is not able to reasonably estimate the expected amount or range of cost or any loss associated with the lawsuit.

Accounting Estimates

Accounting Estimates

The preparation of financial statements in conformity with GAAP requires 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 revenue and expenses during the reporting periods. Areas of the financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, certain deferred costs, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.

Recently Adopted Accounting Standards and Recent Accounting Pronouncements Not Yet Adopted

Recently Adopted Accounting Standards

The Company has accounted for the tax effects of the Tax Cuts and Jobs Act, or the 2017 Tax Act, under the guidance of Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, or SAB 118, on a provisional basis as of the fourth quarter of fiscal 2018. During the three months ended September 30, 2018, the Company continued its assessment of the 2017 Tax Act, including the potential accounting impact for any new guidance issued during the quarter. The Company made immaterial provisional adjustments associated with the limitation on the deductibility of certain executive compensation based on its preliminary assessment of the recently issued IRS Notice 2018-68. There were no additional changes to the provisional amounts recorded at March 31, 2018. The Company expects to complete its accounting assessment within the prescribed measurement period. See Note 10 to our consolidated financial statements for further information regarding the updated effects of the 2017 Tax Act during the second quarter of fiscal 2019.

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Codification No. 606, Revenue from Contracts with Customers (Topic 606). Topic 606, as amended, replaced existing revenue recognition standards by outlining a single set of comprehensive principles for recognizing revenue. The revenue standard also significantly expanded the disclosure requirements for revenue arrangements. Amendments to Topic 606 have generally focused on promoting a more consistent interpretation and application of the principles for recognizing revenue.

Topic 606 was effective for the Company beginning on April 1, 2018 (i.e., beginning with the first quarter fiscal 2019 interim financial statements). The Company adopted the new revenue standard using the full retrospective transition method, which requires that it be applied to each prior reporting period presented and that the cumulative effect of applying the standard be recognized at the earliest period presented (i.e., April 1, 2016, the beginning of the first quarter of fiscal 2017). During fiscal 2018, the Company completed its assessment of the cumulative effect of adopting Topic 606 and assessed the impact to be immaterial as of the date of adoption.

In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This guidance requires a customer in a cloud computing arrangement that is a service contract to follow existing internal-use software guidance to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with that of implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 is effective for interim reporting periods for fiscal years beginning after December 15, 2019. Early adoption is permitted. The standard may be adopted either retrospectively or prospectively. The Company is currently assessing the future impact of this update on its consolidated financial statements and related disclosures.

In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. This guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Additionally, the guidance also expands an entity's ability to apply hedge accounting for nonfinancial and financial risk components, simplifies the hedge documentation and hedge effectiveness assessment requirements, and modifies certain disclosure requirements. ASU 2017-12 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability of accounting for lease transactions. The new leasing standard requires lessees to recognize lease assets and lease liabilities on their balance sheet for all leases with a lease term of greater than 12 months. Lessor accounting is largely unchanged. Topic 842 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB provided an alternative transition method of adoption through ASU No. 2018-11, Targeted Improvements, which permits the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company intends to adopt the standard beginning in fiscal 2020 using the modified retrospective transition approach, specifically, using the alternative transition method provided by ASU 2018-11.

A dedicated implementation team has been established that continues to make progress toward completing the evaluation of the impact of the new standard. The Company's assessment efforts to date have included reviewing the provisions of Topic 842, gathering information to evaluate its lease population and portfolio, evaluating the nature of real and personal property and other arrangements that may meet the definition of a lease, designing and implementing one-time implementation controls as well as new post-adoption lease processes and controls, implementing a new lease accounting software solution, and evaluating certain accounting policy elections. The Company anticipates finalizing its accounting policy, accounting software, systems and process modifications during the fourth quarter of fiscal 2019.

Based on a preliminary assessment, the Company does not expect there to be a significant change in determining what constitutes a lease, however, the Company expects that virtually all of its operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in a significant increase in the assets and liabilities on its consolidated balance sheets. The pattern of recognition for operating leases within the consolidated statements of operations and comprehensive income is not anticipated to significantly change. The adoption is not expected to impact the Company’s ability to comply with financial covenants as defined within the Company's Sixth Amendment to its Credit Agreement dated July 23, 2018, as discussed further in Note 8, Debt. The Company is continuing to refine its process for quantifying the financial statement impacts and anticipates finalizing its assessment of the materiality of adopting Topic 842 in conjunction with reporting its results for the third quarter of fiscal 2019.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The amendments set forth certain presentation requirements, including that such analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed with all significant reconciling items described by appropriate captions with contributions from and distributions to owners shown separately. This final rule is effective 30 days after publication in the Federal Register and will generally be effective for the Company for the third quarter of fiscal year 2019. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

Other accounting and reporting pronouncements issued after September 30, 2018 and through the filing date are not expected to have a material impact on the Company's condensed consolidated financial statements.

(1) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 9 for further discussion on the Company’s derivative instruments designated as cash flow hedges.

(2)Investments in this category consist primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our condensed consolidated balance sheets.

(3) The Company recognized a contingent consideration liability of $3.6 million in connection with its acquisition of Aquilent in fiscal 2017. As of September 30, 2018 and March 31, 2018, the estimated fair value of the contingent consideration liability was $3.3 million and $3.6 million, respectively, and was valued using probability-weighted cash flows, which is based on the use of Level 3 fair value measurement inputs. The liability is recorded in other long-term liabilities in the condensed consolidated balance sheet.
