| Plan modification description | Effective April 30, 2010, the Pension Plan was amended, resulting in a "soft freeze", the effect of which prohibits new entrants into the plan and ceases crediting of additional years of service, after that date. Effective January 1, 2013, the Pension Plan was amended to unfreeze it for those employees for whom the sum of (i) their ages, at their closest birthday, plus (ii) years of service for vesting purposes equals 80 or greater. The "soft freeze" continues to apply to all other plan participants. Pension benefits for these participants will be managed through discretionary contributions to the First United Corporation 401(k) Profit Sharing Plan (the "401(k) Plan"). | ||||
