10. Commitments and Contingencies

Leases

The Company conducts all of its operations in leased facilities and leases certain equipment which have minimum lease obligations under noncancelable operating leases. Certain of these leases contain rent escalations based on specified percentages. Most of the leases contain renewal options and require payments for taxes, insurance and maintenance. Rent expense is charged to operations as incurred except for escalating rents, which are charged to operations on a straight-line basis over the life of the lease.

A summary of rental expense for the three years ended December 31, 2011, 2010, and 2009, is presented below, as well as the future minimum lease commitments under noncancelable operating leases having an initial term of more than one year (in thousands):

Legal Matters

The Company is involved, from time to time, in litigation and proceedings arising out of the ordinary course of business. Legal costs for services rendered in the course of these proceedings are charged to expense as they are incurred.

The Company is involved in a number of governmental interactions primarily related to the commercialization of our PPM service. A contingent loss in the amount of $0.4 million and $0.5 million for these claims was recorded in accrued expenses and other current liabilities on the Company's consolidated balance sheets as of December 31, 2011, and December 31, 2010, respectively.
