Commitments and Contingencies

Contracts with the U.S. government including subcontracts are subject to extensive legal and regulatory requirements and, from time to time, agencies of the U.S. government, in the ordinary course of business, investigate whether the Company's operations are conducted in accordance with these requirements and the terms of the relevant contracts. 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 Audit Agency (DCAA) has completed our incurred cost audits through 2002 and the majority of the audits for 2003, 2004 and 2005, with no material adjustments. The remaining audits for 2003 through 2011 are not expected to have a material effect on our financial position, results of operations or cash flow and management believes it has adequately reserved for any losses.

In the normal course of business, we are involved in certain governmental and legal proceedings, claims and disputes and have litigation pending under several suits. We believe that the ultimate resolution of these matters will not have a material effect on our financial position, results of operations or cash flows.

We lease office space and equipment under long-term operating leases. A number of the leases contain renewal options and escalation clauses. At December 31, 2011, aggregate future minimum rental commitments under these leases are as follows (in thousands):

	Office Space		Equipment		Total
Year ending:
December 31, 2012	$	29,584	$	961	$	30,545
December 31, 2013	27,813		767		28,580
December 31, 2014	23,415		28		23,443
December 31, 2015	21,404		9		21,413
December 31, 2016	19,661		—		19,661
Thereafter	110,072		—		110,072
Total	$	231,949	$	1,765	$	233,714

Office space and equipment rent expense totaled approximately $55.2 million, $47.9 million and $51.4 million for the years ended December 31, 2011, 2010 and 2009, respectively.

We had $7.1 million and $6.9 million of deferred rent liabilities resulting from recording rent expense on a straight-line basis over the life of the respective lease for the years ended December 31, 2011 and 2010, respectively.
