Retirement Plans [Abstract] |
Retirement Plans | (14) RETIREMENT PLANS In May 1986, the Company adopted the BancFirst Corporation Employee Stock Ownership ("ESOP") and Thrift Plan ("401(k)") effective January 1, 1985. The plan was separated into two individual plans effective January 1, 2009. The 401(k) and ESOP plans cover all eligible employees, as defined in the plans, of the Company and its subsidiaries. The 401(k) plan allows employees to defer up to the maximum legal limit of their compensation, of which the Company may match 50%, but not to exceed 3% of their compensation. In addition, the Company may make discretionary contributions based on employee contributions or eligible compensation to the ESOP plan, as determined by the Company's Board of Directors. The aggregate amounts of contributions by the Company to the 401(k) and ESOP plans are shown in the following table:
