11. SUPPLEMENTAL EXECUTIVE RETIREMENT PLANS

In 1995, 2001, 2004 and 2006, the Bank established Supplemental Executive Retirement Plans ("SERP"), which provide certain (current and former) officers of the Company with supplemental retirement benefits. On December 31, 2002, the 1995 and 2001 SERP were curtailed. In conjunction with the September 2004 merger with CB Bancshares, Inc. ("CBBI"), the Company assumed CBBI's SERP obligation.

The projected benefit obligation of the unfunded SERP is recorded in other liabilities on the Company's consolidated balance sheets. The projected benefit obligation was $9.2 million at March 31, 2024, which remained relatively unchanged from $9.3 million at December 31, 2023.

The following table presents the components of net periodic benefit cost for the SERP for the periods presented:
