Business Overview	9 Months Ended
Business Overview	Dec. 31, 2012
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BUSINESS OVERVIEW	BUSINESS OVERVIEW Organization Booz Allen Hamilton Holding Corporation, including its wholly owned subsidiaries, or Holding or the Company, is an affiliate of The Carlyle Group, or Carlyle, and was incorporated in Delaware in May 2008. The Company provides management and technology consulting services primarily to the U.S. government and its agencies in the defense, intelligence, and civil markets. The Company offers clients functional knowledge spanning strategy and organization, analytics, technology, engineering, and operations, which it combines with specialized expertise in clients’ mission and domain areas to help solve critical problems. The Company reports operating results and financial data in one operating segment. The Company is headquartered in McLean, Virginia, with approximately 24,800 employees as of December 31, 2012.

Basis of Presentation	9 Months Ended
Basis of Presentation	Dec. 31, 2012
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The Company prepared the unaudited condensed consolidated financial statements in this Quarterly Report on Form 10-Q, or Quarterly Report, in accordance with accounting principles generally accepted in the United States, or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. As a result, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The Company followed the accounting policies used and disclosed in the consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended March 31, 2012 filed with the Securities and Exchange Commission on May 30, 2012, or Annual Report, and policies stated within this Form 10-Q. 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 interim financial information in this Quarterly Report reflects all adjustments, consisting of normal recurring adjustments except as otherwise disclosed, necessary for a fair presentation of the Company’s results of operations for the interim periods. The results of operations for the nine months ended December 31, 2012 are not necessarily indicative of results to be expected for the full fiscal year. 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 allowance for doubtful accounts, contractual and regulatory reserves, valuation and lives of tangible and intangible assets, impairment of long-lived assets, accrued liabilities, revenue recognition, bonus and other incentive compensation, stock-based compensation, realization of deferred tax assets, provisions for income taxes, and postretirement obligations. Actual results experienced by the Company may differ materially from management's estimates. Business Combinations and Goodwill The Company has engaged in business acquisition activity. The accounting for business combinations requires management to make judgments and estimates of the fair value of assets acquired, including the identification and valuation of intangible assets, as well as liabilities and contingencies assumed. Such judgments and estimates directly impact the amount of goodwill recognized in connection with each acquisition, as goodwill presents the excess of the purchase price of an acquired business over the fair value of its net tangible and identifiable intangible assets. Recent Accounting Pronouncements Recent accounting pronouncements issued by the FASB during the nine months ended December 31, 2012, and through the filing date did not or are not believed by management to have a material impact on the Company's present or historical condensed consolidated financial statements.

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

Earnings Per Share

9 Months Ended

Dec. 31, 2012

Earnings Per Share [Abstract]

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, Class B Non-Voting Common Stock, Class C Restricted Common Stock, and Class E Special Voting Common Stock. Class E Special Voting Common Stock shares are not included in the calculation of EPS as these shares represent voting rights only and are not entitled to participate in dividends or other distributions. Unvested Class A Restricted Common Stock and unvested Class C Restricted Common Stock holders are entitled to participate in dividends or other distributions. These unvested shares participated in the Company's dividends declared and paid in the first, second and third quarters of fiscal 2013, and as such, EPS is calculated using the two-class method, whereby earnings are reduced by distributed and undistributed earnings, if available, that the restricted shareholders may participate in. No such dividends were paid in the first, second and third quarters of fiscal 2012, as such EPS is calculated using the treasury stock method. A reconciliation of the income used to compute basic and diluted EPS for the periods presented are as follows:

Acquisitions

Business Combinations [Abstract]

ACQUISITIONS

On November 30, 2012 Booz Allen Hamilton Engineering Holding Co., LLC, a wholly owned subsidiary of the Company, acquired the Defense Systems Engineering and Support, or DSES, division of ARINC Incorporated, or ARINC, by acquiring 100% of the membership interests of ARINC Engineering Services, LLC, a wholly owned subsidiary of ARINC that owns DSES. DSES is a provider of advanced aviation and maritime engineering, advanced weapons modernization and sustainment, and advanced systems engineering and integration. DSES has approximately 900 employees. The acquisition aligns with the Company's strategic initiatives to expand existing engineering capabilities and defense market position.

The acquisition of DSES was accounted for under the acquisition method of accounting which requires the total purchase price consideration to be allocated to the assets acquired and liabilities assumed based on estimates of fair value. The Company paid approximately $155.1 million in cash to ARINC for DSES on November 30, 2012, which includes a preliminary purchase price per the agreement of $154.0 million and an estimated $1.1 million as a preliminary working capital adjustment. Under the terms of the purchase agreement, ARINC has ninety days after the closing date to provide DSES' final balance sheet and net working capital as of the closing date. The Company used preliminary information obtained in connection with the acquisition to complete the purchase price allocations related to the acquisition. The Company expects to recover an estimated $2.8 million from ARINC as the preliminary net working capital is lower than that paid. Therefore the Company has accounted for this return of consideration and the purchase price allocation was adjusted to assume a purchase price of $152.2 million. The final purchase price allocations will be completed after the information has been finalized and agreed upon by both parties of the transaction. Preliminary transaction costs were approximately $4.0 million, which were recorded as general and administrative expense as incurred.

The following table represents the preliminary purchase price allocations of DSES' assets and liabilities at fair value:



Current assets	75,669
Current liabilities	(39,504	)
Other tangible assets	3,683
Other liabilities	(300	)
Goodwill	86,180
Identifiable intangible assets	26,500

The goodwill of $86.2 million is largely attributed to the specialized workforce and the expected synergies between the Company and DSES. Substantially all of the goodwill is expected to be deductible for tax purposes. The value attributed to the identifiable intangible assets of $26.5 million is expected to be amortized over the estimated useful life of 7 years.

Pursuant to the purchase agreement, the Company entered into a transition services agreement, or TSA, with ARINC. The TSA requires ARINC to provide certain support services to the Company for up to 12 months following November 30, 2012. Expenses incurred by the Company under the TSA are not material to the Company's consolidated results of operations.

On December 31, 2012 the Company closed an acquisition of an immaterial engineering services company that will also be accounted for using the acquisition method of accounting.

Proforma results of operations for these acquisitions are not presented because neither are material to the Company's consolidated results of operations.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

On July 31, 2012, the Company consummated a recapitalization transaction, or Recapitalization Transaction, which included the refinancing and termination of the Company's existing senior secured credit agreement with the proceeds of the borrowings under the Company's new senior secured credit agreement, or Credit Agreement. The Credit Agreement provided the Company with a $725.0 million Term Loan A tranche and a $1,025.0 million Term Loan B tranche, and a $500.0 million revolving credit facility, with a sublimit for letters of credit of $100.0 million. The outstanding obligations under the Credit Agreement are secured by a security interest in substantially all of the assets of the Company, subject to certain exceptions set forth in the Credit Agreement and related documentation.

The Credit Agreement requires quarterly principal payments of 1.25% of the stated principal amount of Tranche A Loans, with annual incremental increases to 1.875%, 2.50%, 3.125%, and 13.0%, prior to the Tranche A Loans' maturity date of December 31, 2017, and 0.25% of the stated principal amount of Tranche B Loans, with the remaining balance payable on the Tranche B Loans' maturity date of July 31, 2019. The revolving credit facility matures on December 31, 2017, at which time any outstanding principal balance is due in full. As of December 31, 2012 and March 31, 2012, there were no amounts outstanding on the revolving credit facility.

The interest rate on borrowings under Tranche A is LIBOR plus 2.75%, and will range from 2.00% to 2.75% based on the Company's total leverage ratio. The interest rate on borrowings under Tranche B is LIBOR plus 3.5% with a 1% floor. The revolving credit facility margin and commitment fee are subject to the leveraged based pricing grid, as set forth in the Credit Agreement.

Prior to the Recapitalization Transaction, the Company maintained a senior secured credit agreement, as amended, with a syndicate of lenders. The senior secured credit agreement, as amended, provided for $1.0 billion in term loans ($500.0 million of Tranche A Loans and $500.0 million of Tranche B Loans) and a $275.0 million revolving credit facility. The loans under the senior secured credit agreement, as amended, were secured by substantially all of the Company’s assets.

The total outstanding debt balance is recorded in the accompanying condensed consolidated balance sheets, net of unamortized discount of $12.0 million and $4.6 million as of December 31, 2012 and March 31, 2012, respectively.

As of December 31, 2012 and March 31, 2012, the Company was in compliance with all of its debt covenants.

Grants of Class A Restricted Common Stock

On June 29, 2012, the Board of Directors granted 674,456 shares of Class A Restricted Stock in conjunction with the Annual Incentive Plan adopted on October 1, 2010. The amount of the annual incentive payment was determined based on performance targets established by the Compensation Committee and a portion of the bonus was paid in the form of Class A Restricted Stock. Equity awards will vest based on the passage of time, subject to the officer’s continued employment by the Company. The portion to be paid in the form of equity will be recognized in the accompanying consolidated statements of operations based on grant date fair value over the vesting period of three years and the aggregate value was estimated at $10.3 million based on the stock price of $15.28 on the grant date. On August 2, 2012, the Board of Directors granted 24,251 shares of Class A Restricted Stock to certain members of the Board of Directors.

Dividends

On May 29, 2012, our Board of Directors authorized and declared a regular quarterly cash dividend in the amount of $0.09 per share. In addition, the Board of Directors declared a special cash dividend of $1.50 per share. Both the quarterly and special dividend were paid on June 29, 2012 to stockholders of record on June 11, 2012. The Compensation Committee, as the Administrator of the Officers' Rollover Stock Plan and the EIP, made a required adjustment to the outstanding options under each plan by granting holders of the Rollover Options a cash payment equal to the amount of the special dividend on the options' mandatory exercise date and by granting the holders of EIP options a dividend equivalent equal to the special dividend and payable on June 29, 2012 or the vesting of the EIP option, whichever is later.

On July 30, 2012, our Board of Directors authorized and declared a special cash dividend of $6.50 per share and a regular quarterly cash dividend in the amount of $0.09 per share. The dividends were accounted for on July 31, 2012, the declaration date, by reducing retained earnings to zero with the remainder being recorded as a reduction to additional paid-in capital. The dividends were paid on August 31, 2012 to stockholders of record on August 13, 2012 for the special cash dividend and August 14, 2012 for the regular quarterly cash dividend. The Board of Directors, as the Administrator of the Officers' Rollover Stock Plan and the EIP, made a determination to adjust the outstanding options under each plan.

Holders of the Rollover Options received a cash payment equal to the amount of the special dividend on the options' mandatory exercise date. On August 31, 2012 and December 31, 2012, Rollover Options holders received a dividend equivalent payment of $9.0 million and $12.0 million, respectively, related to the special dividends. Holders of EIP options with a pre-dividend exercise price less than $11.00 per share received a dividend equivalent equal to the amount of the special dividend payable on August 31, 2012 or the vesting of the EIP option, whichever is later. On August 31, 2012, vested outstanding EIP options received a dividend equivalent payment of $28.7 million related to the special dividends. All other EIP options were adjusted, based on authorization from the Board of Directors, by reducing the exercise price by $6.36 which is equal to the difference between the pre-dividend closing fair market value of our Class A Common Stock and the post-dividend opening fair market value of our Class A Common Stock as noted on the New York Stock Exchange. Payment of the dividend equivalents and adjustments to option exercise prices were accounted for as modifications resulting in incremental benefit to the option holders resulting in additional compensation expense of $3.8 million. Total compensation expense recorded in conjunction with the payment of the dividend equivalent to holders of unvested EIP options for the three and nine months ended December 31, 2012 was $117,000 and $2.3 million, respectively. Future compensation cost related to payment of the dividend equivalents to holders of EIP options not yet recognized in the statement of operations is $1.5 million and is expected to be recognized over 4.5 years.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Dec. 31, 2012
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Leases As a result of the July 2008 merger transaction, as described in the Company’s Annual Report, the Company assigned a total of nine leases to Booz & Co. The facilities are located in New York, New York; Troy, Michigan; Florham Park, New Jersey; Parsippany, New Jersey; Houston, Texas; Chicago, Illinois; Cleveland, Ohio; Dallas, Texas; and London, England. Except for the Houston, Cleveland and Dallas leases, which expired, the Company remains liable under the terms of the original leases should Booz & Co. default on its obligations. There were no events of default under these leases as of December 31, 2012 or March 31, 2012. The maximum potential amount of undiscounted future payments is $27.6 million, and the leases expire at different dates between February 2013 and March 2017. Based on the Company’s assessment of the likelihood of future payment, no amounts have been recorded related to the Company’s contingent liability on such leases. Government Contracting Matters For the three and nine months ended December 31, 2012, approximately 99% of the Company’s revenue was generated from contracts with U.S. government agencies or other U.S. government contractors, and approximately 98% for the three and nine months ended December 31, 2011. Contracts with the U.S. government are subject to extensive legal and regulatory requirements and, from time to time and in the ordinary course of business, agencies of the U.S. government investigate whether the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts by using investigative techniques such as subpoenas or civil investigative demands. U.S. government investigations of the Company, whether related to the Company’s U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including 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 adequately reserved for any losses that may be experienced from any investigation of which it is aware. The Defense Contract Management Agency Administrative Contracting Officer has negotiated annual final indirect cost rates through fiscal year 2006. Audits of subsequent years may result in cost reductions and/or penalties. Management believes it has adequately reserved for any losses that may be experienced from any such reductions and/or penalties. As of December 31, 2012 and March 31, 2012, the Company has recorded a liability of approximately $149.9 million and $127.2 million, respectively, for its current best estimate of amounts to be refunded to customers for potential adjustments from such audits or reviews of contract costs incurred subsequent to fiscal year 2006. 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 that currently range up to $40 million or have a reasonably estimated outcome within that range, 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. Six former officers and stockholders who had departed the firm prior to July 31, 2008, the date on which we became majority owned by The Carlyle Group and certain of its affiliated investment funds, as described in the Company’s Annual Report, or the Acquisition, have filed a total of nine suits in various jurisdictions, with original filing dates ranging from July 3, 2008 through December 15, 2009 (three of which were amended on July 2, 2010 and then further amended into one consolidated complaint on September 7, 2010) against the Company and certain of the Company’s current and former directors and officers. Each of the suits arises out of the 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 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 Employee Retirement Income Security Act, and/or securities and common law fraud. Two of these suits have been dismissed with all appeals exhausted. Five of the remaining suits are pending in the United States District Court for the Southern District of New York, the sixth is pending in New York state court and the seventh is pending in the United States District Court for the Southern District of California. As of December 31, 2012 and March 31, 2012, the aggregate alleged damages sought in the seven remaining suits was approximately $348.7 million ($291.5 million of which is sought to be trebled pursuant to RICO) plus punitive damages, costs, and fees. 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.
