As a result of the termination of the SERP program, the accrued pension liability of $7.6 million was reversed and replaced with this pension annuity liability of $7.5 million. The valuation of the liability is based on the present value of $10.2 million discounted at a rate of 4.25% over a 15-year term, resulting in a monthly payment of $57,000. The discounted value of $2.7 million (which is the difference between the estimated payout of $10.2 million and the present value of $7.5 million) as of August 29, 2014 will be amortized and expensed based on the 15-year term. In addition, the accumulated actuarial loss of $3.1 million recorded, as part of other comprehensive income will also be amortized based on the 15-year term. In February 2018, we made a payment of $2.4 million relating to the annuity representing payments for the 42 months outstanding at the time. Monthly ongoing payments of $57,000 are now being made. As a result of the above, included in our current and non-current liabilities are accrued pension costs of $4.4 million at September 30, 2021. The benefits of our pension plan are fully vested and therefore no service costs were recognized for the nine months ended September 30, 2021 and 2020. Our pension plan is unfunded. During the quarter and nine months ended September 30, 2021, the interest cost was $59,000 and $182,000, respectively, and the actuarial loss was $52,000 and $156,000, respectively. During the quarter and nine months ended September 30, 2020, the interest cost was $65,000 and $199,000, respectively, and the actuarial loss was $52,000 and $155,000, respectively.
