13. Legal Expenses, Exposures and contingencies.

The Company and its subsidiaries are parties to legal proceedings which have arisen in the normal course of their activities. Although the amount of the Company's ultimate liability, if any, with respect to these matters can not be determined with reasonable certainty, management, after consultation with legal counsel, believes that the resolution of such matters will not have a material adverse effect upon the Company's consolidated financial position, results of operations and cash flows.

The Company estimates the costs associated with known legal exposures and their related legal expenses and accrues reserves for either the probable liability, if that amount can be reasonably estimated, or otherwise the lower end of an estimated range of potential liability.

During the three and nine months ended September 30, 2011, the company recorded a one-time, non-recurring charge to earnings to resolve all claims brought as part of an arbitration proceeding with a former client arising out of a 2004 engagement, which resulted in a onetime expense of net $12.6 million and an increase in revenue of approximately $0.96 million.
