NCUA is revising its rules concerning maximum borrowing authority to permit federally insured, state-chartered credit unions (FISCUs) to apply for a waiver from the maximum borrowing limitation of 50 percent of paid-in and unimpaired capital and surplus (shares and undivided earnings, plus net income or minus net loss). This amendment will provide FISCUs with more flexibility by allowing them to apply for a waiver up to the amount permitted under state law. NCUA is also adding a provision to its regulations that allows a federal credit union (FCU) to act as surety or guarantor on behalf of its members. The final rule establishes certain requirements to ensure that FCUs, and FISCUs if permitted under state law to act as a surety or guarantor, are not exposed to undue risk.
