In addition, we have commitments to certain former and current senior executives under a supplemental executive retirement plan (“SERP”). The present value of expected payments under the SERP was $12.4 million and $10.1 million at December 31, 2011 and 2010, respectively, and benefits are payable over the ten years following the cessation of employment by the executive. In addition, the employment agreement of a former executive provides for supplemental benefits for a period of 10 years similar to those provided under the SERP plan. The present value of expected payments under this employment agreement was $1.4 million and $1.5 million at December 31, 2011 and 2010, respectively.
