A participating director may elect to have amounts deferred under the Deferred Compensation Plan held in a deferred cash account, which is credited on a quarterly basis with interest equal to the highest rate offered by the Bank at the end of the preceding quarter. Alternatively, a participant may elect to have a deferred stock account in which deferred amounts are treated as if invested in the Company’s common stock at the fair market value on the date of deferral. The value of a stock account will increase and decrease based upon the fair market value of an equivalent number of shares of common stock. In addition, the deferred amounts deemed invested in common stock will be credited with dividends on an equivalent number shares. Amounts considered invested in the Company’s common stock are paid, at the election of the director, either in cash or in whole shares of the common stock and cash-in-lieu of fractional shares. Directors may elect to receive amounts contributed to their respective accounts in one or up to five installments. No directors participated in the Deferred Compensation Plan during the three and nine months ended September 30, 2018 and 2017. The Company has a nonqualified deferred compensation program for a former key employee’s retirement, in which the contribution expense is solely funded by the Company. The retirement benefit to be provided is variable based upon the performance of underlying life insurance policy assets. Deferred compensation expense for the three and nine months ended September 30, 2018 was $9,000 and $36,000, respectively. Deferred compensation expense for the three and nine months ended September 30, 2017 was $7,000 and $7,000, respectively. Concurrent with the establishment of the deferred compensation program, the Company purchased life insurance policies on this employee with the Company named as owner and beneficiary. These life insurance policies are intended to be utilized as a source of funding the deferred compensation program. Income on these life insurance policies amounted to $7,000 for the three months ended September 30, 2018 and 2017, and $21,000 and for the nine months ended September 30, 2018 and 2017. The Company has recorded on its consolidated balance sheets $1.3 million in cash surrender value of these policies at September 30, 2018 and December 31, 2017, and $103,000 and $93,000, respectively, in accrued liabilities.
