These policies provide: (1) financial protection to the Company in the event of the death of a key employee; and (2) since the interest earned on the cash surrender value of the policies is tax exempt as long as the policies are used to finance employee benefits, significant income to the Company to offset the expense associated with the Executive Retirement Plan and other employee benefit plans. As compensation to each employee for agreeing to allow the Company to purchase an insurance policy on his or her life, split dollar agreements have been entered into with those employees. These agreements provide for a division of the life insurance death proceeds between the Company and each employee's designated beneficiary or beneficiaries. The Company earned tax-exempt interest on the life insurance policies of $1.8 million for the years ended December 31, 2011, 2010, and 2009.
