1. BUSINESS OVERVIEW Organization Booz Allen Hamilton Holding Corporation, including its wholly owned subsidiaries, or 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, an affiliate of The Carlyle Group, or Carlyle, was incorporated in Delaware in May 2008 and is headquartered in McLean, Virginia, with approximately 26,000 employees as of September 30, 2011.

2. BASIS OF PRESENTATION The Company prepared the 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, 2011 filed with the Securities and Exchange Commission on June 8, 2011, or Annual Report. 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 six months ended September 30, 2011 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. Actual results experienced by the Company may differ materially from management’s estimates. Recent Accounting Pronouncements In September 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update 2011-08, Testing Goodwill for Impairment, which amends Topic 350, Intangibles – Goodwill and Other. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. The guidance is effective for interim and annual goodwill impairment tests performed for fiscal years beginning after December 15, 2011 and early adoption is permitted. The Company will early adopt as of our measurement date, January 1, 2012. The implementation of this guidance will not have a material impact on the Company’s condensed consolidated financial statements. Other recent accounting pronouncements issued by the FASB during the three months ended September 30, 2011 and through the filing date did not or are not believed by management to have a material impact on the Company’s condensed consolidated financial statements.

3. 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 is computed similar to basic EPS, except the weighted average number of shares outstanding is increased 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.   Basic and diluted EPS for the periods presented are computed as follows:   <table cellspacing="0" cellpadding="0" width="92%" border="0" style="border-collapse:collapse; text-align:

For the three and six months ended September 30, 2011, 514,896 shares of Class A Common Stock with certain restrictions, or Class A Restricted Stock, were not included in the EPS calculation as they have not vested. Such options and Class A Restricted Stock may have a dilutive effect in future periods.

4. GOODWILL AND INTANGIBLE ASSETS Goodwill As of September 30, 2011 and March 31, 2011, goodwill was $1,177.0 million and $1,163.5 million, respectively. The increase in the carrying amount of goodwill is primarily attributable to the increase in the deferred payment obligation as a result of the release of approximately $24.0 million of reserves for uncertain tax positions, partially offset by a $10.7 million reduction to goodwill related to the sale of the Company’s state and local transportation business. Intangible Assets Intangible assets consisted of the following:   <table cellspacing="0" cellpadding="0" width="100%" border="0" style="border-collapse:collapse; text-align: left" align="center">

7. DEFERRED PAYMENT OBLIGATION In connection with the merger transaction as described in the Company’s Annual Report, or the acquisition, the Company established a deferred payment obligation, or DPO, of $158.0 million, payable 8.5 years after July 31, 2008, less any settled claims. Of the $158.0 million, $78.0 million was required to be paid in full to the selling shareholders and $80.0 million is available to indemnify the Company for certain pre-acquisition tax contingencies, related interest and penalties, and other matters pursuant to the Agreement and Plan of Merger dated as of May 15, 2008, as amended as of July 30, 2008. On December 11, 2009, in connection with the recapitalization transaction as described in the Company’s Annual Report, $100.4 million was paid to selling shareholders, of which $78.0 million was the repayment of that portion of the DPO described above, with $22.4 million representing accrued interest. Any amounts remaining after the settlement of claims will be paid out to selling shareholders. As of September 30, 2011 and March 31, 2011, the Company has recorded $66.3 million and $90.5 million, respectively, for pre-acquisition uncertain tax positions, of which approximately $28.5 million and $52.7 million, respectively, may be indemnified under the remaining available DPO. During the six months ended September 30, 2011, the Company favorably settled approximately $29.0 million of its pre-acquisition uncertain tax positions, thereby reducing the estimated amount to be indemnified under the remaining available DPO and increasing the DPO amount to be paid to the selling shareholders. Accordingly, the $67.0 million and $38.2 million DPO balances recorded as of September 30, 2011 and March 31, 2011, respectively, within other long-term liabilities in the accompanying condensed consolidated balance sheets, represent the residual balance estimated to be paid to the selling shareholders based on consideration of contingent tax claims, accrued interest, and other matters.

secured credit agreement, as amended, with a syndicate of lenders. The senior secured credit agreement, as amended, provides 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, are secured by substantially all of the Company’s assets. The senior secured agreement, as amended, requires quarterly principal payments of 1.25% of the stated principal amount of the Tranche A Loans, with annual incremental increases to 1.875%, 2.50%, 3.125%, and 16.25%, prior to the Tranche A Loans’ maturity date of February 3, 2016, and 0.25% of the stated principal amount of the Tranche B Loans, with the remaining balance payable on the Tranche B Loans’ maturity date of August 3, 2017. The revolving credit facility matures on July 31, 2014, at which time any outstanding principal balance is due in full. As of September 30, 2011 and March 31, 2011, there were no amounts outstanding on the revolving credit facility. The total outstanding debt balance is recorded in the accompanying condensed consolidated balance sheets, net of unamortized discount of $5.1 million and $5.7 million as of September 30, 2011 and March 31, 2011, respectively. At September 30, 2011 and March 31, 2011, the Company was contingently liable under open standby letters of credit and bank guarantees issued by the Company’s banks in favor of third parties. These letters of credit and bank guarantees, which totaled $2.2 million and $1.9 million as of September 30, 2011 and March 31, 2011, respectively, primarily relate to leases and support of insurance obligations. These instruments reduce the Company’s available borrowings under the revolving credit facility. The senior secured credit agreement, as amended, requires the maintenance of certain financial and non-financial covenants. As of September 30, 2011 and March 31, 2011, the Company was in compliance with all of its covenants.

9. INCOME TAXES The Company’s effective income tax rate was 11.9% and 43.6% for the three months ended September 30, 2011 and 2010, respectively, and 26.0% and 42.2% for the six months ended September 30, 2011 and 2010, respectively. The decrease in the effective tax rate for the three and six months ended September 30, 2011 as compared to the same prior year periods is primarily due to the release of uncertain tax position reserves in the current quarter. The three and six month effective tax rate of 11.9% and 26.0%, respectively, differ from the statutory rate of 35.0% due to the release of uncertain tax positions, state taxes and the effect of other permanent rate differences, which primarily related to meals and entertainment. The Company settled its Internal Revenue Service, or IRS, audit for fiscal years 2004, 2005, and 2006 during the quarter. The IRS adjusted the Company’s research credit claims for the audit years. The adjustments did not result in a material change to the Company’s financial position. Due to the federal audit settlement, the Company released approximately $24.0 million of reserves for uncertain tax positions in the current quarter. The Company is also subject to taxes imposed by various taxing authorities including state and foreign jurisdictions. Tax years that remain open and subject to examination related to state and foreign jurisdictions are not considered to be material or will be indemnified under the merger agreement as described in the Company’s Annual Report. Additionally, due to statute of limitations expirations and potential audit settlements, it is reasonably possible that a portion of the reserves recorded on previously recognized tax benefits may be effectively settled by March 31, 2012. During the three months ended September 30, 2011, the Company utilized $14.9 million of its capital loss carryforward from the disposition of the state and local transportation business. In prior periods, the Company had provided a full valuation allowance against the deferred tax assets associated with the capital loss carryforward. As a result, the Company recognized an income tax benefit of $5.9 million in the three and six months ended September 30, 2011.

10. 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. Total expense recognized under ECAP for the three months ended September 30, 2011 and 2010 was $55.5 million and $57.3 million, respectively, and $114.7 million and $113.6 million for the six months ended September 30, 2011 and 2010, respectively. The Company-paid contributions for the three months ended September 30, 2011 and 2010 were $28.3 million and $24.6 million, respectively, and $70.0 million and $62.2 million for the six months ended September 30, 2011 and 2010, respectively. Defined Benefit Plan and Other Postretirement Benefit Plans The Company maintains and administers a defined benefit retirement plan and a postretirement medical plan for current, retired, and resigned officers. Total expense for the Company’s Retired Officers’ Bonus Plan was $217,000 and $216,000 for the three months ended September 30, 2011 and 2010, respectively, and $434,000 and $432,000 for the six months ended September 30, 2011 and 2010, respectively. The Retired Officers’ Bonus Plan is an unfunded plan and contributions are made as benefits are paid. As of September 30, 2011 and March 31, 2011, the accumulated liability of $4.7 million and $5.2 million, respectively, included in other long-term liabilities in the accompanying condensed consolidated balance sheets is unfunded.   The components of net postretirement medical expense for the Officer Medical Plan were as follows:   <table cellspacing="0" cellpadding="0" width="92%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="72%"> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="3%"> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="6" align="center" style="border-bottom:1px solid #000000">Three Months Ended September 30,</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="6" align="center" style="border-bottom:1px solid #000000">Six Months Ended September 30,</td> <td valign="bottom"> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2011</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2010</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2011</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">2010</td> <td valign="bottom"> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Service cost </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,000</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">841</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,956</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,682</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> Interest cost </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">724</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">642</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,493</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,284</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Total postretirement medical expense </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,724</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,483</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">3,449</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">2,966</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr>  </table> As of September 30, 2011 and March 31, 2011, the unfunded status of the Officer Medical Plan was $55.5 million and $52.8 million, respectively, and is included in other long-term liabilities in the accompanying condensed consolidated balance sheets.

The unrecognized compensation cost as of September 30, 2011 is expected to be amortized over the next 4.75 years.   Officers’ Rollover Stock Plan For the three and six months ended September 30, 2011, 0 and 766,890 shares of Class C Restricted Common Stock, or Class C Restricted Stock, vested, respectively. Total compensation expense recorded in conjunction with all Class C Restricted Stock for the three months ended September 30, 2011 and 2010 was $148,000 and $854,000, respectively, and $740,000 and $2.2 million for the six months ended September 30, 2011 and 2010, respectively.

A portion of the old stock rights held by Booz Allen Hamilton, Inc.’s U.S. government consulting partners issued under the stock rights plan that existed for Booz Allen Hamilton, Inc.’s Officers prior to the merger transaction, as described in the Company’s Annual Report, were exchanged for new options, or Rollover Options. As of September 30, 2011, there were 9,437,102 Rollover Options outstanding, of which 3,758,750 options were unvested. As Rollover Options granted to retirement eligible Officers were fully vested as of September 30, 2011, the remaining 3,758,750 options unvested as of September 30, 2011 represent only non-retirement eligible options. Total compensation expense recorded in conjunction with all Rollover Options for the three months ended September 30, 2011 and 2010 was $2.0 million and $6.6 million, respectively, and $7.1 million and $14.8 million for the six months ended September 30, 2011 and 2010, respectively. Future compensation cost related to non-vested Rollover Options not yet recognized in the condensed consolidated statements of operations was $7.6 million, and is expected to be recognized over 1.75 years. As permitted under the terms of the Officers’ Rollover Stock Plan, or the Rollover Plan, the Compensation Committee, as Administrator of the Rollover Plan, authorized on June 3, 2011 the payment of withholding taxes not to exceed the minimum statutory withholding amount arising in connection with the exercise of Rollover Options through the surrender of shares of Class A common stock, issuable upon the exercise of such Rollover Options. The Company extended this offer to the holders of the Rollover Options to provide for an additional alternative to either paying the minimum required withholding tax arising in connection with the exercise of the Rollover Options from each holder’s existing personal funds or from the proceeds of the open market sale of a portion of the shares issuable upon the exercise of the Rollover Options. The surrender program was limited to the Rollover Options that were required to be exercised between June 30, 2011 and September 15, 2011 and, for those holders who elected to participate, the trade date was August 12, 2011 for the exercise of the Rollover Options. As a result of this transaction, the Company repurchased 333,775 shares at $16.11 and recorded them as treasury shares at a cost of $5.4 million. Equity Incentive Plan On July 1, 2011 and August 10, 2011, 60,000 and 140,000 options, respectively, were granted under the Equity Incentive Plan, or EIP.

As of September 30, 2011, there were 11,867,854 EIP options outstanding, of which 8,149,550 were unvested. Total compensation expense recorded in conjunction with EIP options for the three months ended September 30, 2011 and 2010 was $3.1 million and $4.1 million, respectively, and $8.0 million and $10.2 million for the six months ended September 30, 2011 and 2010, respectively. Future compensation cost related to non-vested EIP options not yet recognized in the condensed consolidated statements of operations was $25.8 million, and is expected to be recognized over 4.75 years. Grants of Class A Restricted Common Stock On April 1, 2011, the Compensation Committee of the Board of Directors granted 20,231 shares of Class A Restricted Stock to certain Board members for their continued service to the Company. These shares vest in equal installments on September 30, 2011 and March 31, 2012, and were issued with an aggregate grant date fair value of $370,000. Total compensation expense recorded in conjunction with this grant for the three and six months ended September 30, 2011 was $139,000 and $278,000 respectively. Future compensation cost related to this award not yet recognized in the condensed consolidated statements of operations was $93,000 and is expected to be recognized over the next six months. There were no additional shares authorized to be issued under the April 2011 Compensation Committee grant. On July 1, 2011, the Compensation Committee of the Board of Directors granted 514,869 shares of Class A Restricted Stock in conjunction with the new 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 $9.8 million based on the stock price of $19.08 on the grant date. Total compensation expense recorded in conjunction with this grant for the three months ended September 30, 2011 was $2.3 million. Future compensation cost related to this award not yet recognized in the condensed consolidated statements of operations was $7.5 million and is expected to be recognized over the next 2.75 years. December 2009 Dividend As of September 30, 2011 and March 31, 2011, the Company recorded a stock-based compensation liability of $25.8 million and $31.4 million, respectively, in other long-term liabilities, related to the reduction in stock option exercise price associated with a dividend paid in December 2009. The Company also recorded $8.9 million and $9.0 million as of September 30, 2011 and March 31, 2011, respectively, of a stock-based compensation liability in accrued compensation and benefits, which represents the amounts of the reduction in stock option exercise price expected to be paid within one year. Options vested and not yet exercised that would have had an exercise price below zero as a result of the dividend were reduced to one cent, with the remaining reduction to be paid in cash upon exercise of the options. Refer to the Company’s Annual Report for further discussion of the dividend paid in December 2009.

13. FINANCIAL INSTRUMENTS The fair value of the Company’s cash and cash equivalents as of September 30, 2011 and March 31, 2011 approximated its carrying value of $356.2 million and $192.6 million, respectively, because of the short-term nature of these accounts. The fair value of the Company’s debt instruments as of September 30, 2011 and March 31, 2011 approximated its carrying value of $979.9 million and $994.3 million, respectively. The fair value of debt is determined based on interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements.

14. RELATED-PARTY TRANSACTIONS The Company is an affiliate of Carlyle and from time to time, and in the ordinary course of business: (1) other Carlyle portfolio companies engage the Company as a subcontractor or service provider, and (2) the Company engages other Carlyle portfolio companies as subcontractors or service providers. Revenue and cost associated with these related parties for the three months ended September 30, 2011 were $343,000 and $305,000, respectively, and $946,000 and $852,000 for the six months ended September 30, 2011, respectively. Revenue and cost associated with these related parties for the three months ended September 30, 2010 were $1.9 million and $1.7 million, respectively, and $5.0 million and $4.3 million for the six months ended September 30, 2010, respectively. On July 31, 2008, the Company entered into a management agreement, or Management Agreement, with TC Group V US, L.L.C., or TC Group, a company affiliated with Carlyle. In accordance with the Management Agreement, TC Group provides the Company with advisory, consulting, and other services and the Company pays TC Group an aggregate annual fee of $1.0 million, plus expenses. For the three months ended September 30, 2011 and 2010, the Company incurred $250,000 in advisory fees. For the six months ended September 30, 2011 and 2010, the Company incurred $500,000 in advisory fees.

15. 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 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 theses leases as of September 30, 2011 and March 31, 2011. The maximum potential amount of undiscounted future payments is $41.4 million, and the leases expire at different dates between February 2012 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 six months ended September 30, 2011 and 2010, 98% of the Company’s revenue was generated from contracts with U.S. government agencies or other U.S. government contractors. 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 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 September 30, 2011 and March 31, 2011, the Company has recorded a liability of approximately $115.8 million and $100.2 million, respectively, for its current best estimate of net 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 claime for monetary damages in varying amounts that currently range up to $40.0 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 the acquisition, as described in the Company’s Annual Report, have filed a total of nine suits, 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 and a third suit has been dismissed but the former stockholder has sought leave to re-plead in New York state court. 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 September 30, 2011 and March 31, 2011, 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, we do not expect them to have a material adverse effect on our financial condition and results of operations.
