(This measure has not been amended since it was introduced. The summary has been expanded because action occurred on the measure.) Small Bank Exam Cycle Reform Act of 2015 (Sec. 2) This bill amends the Federal Deposit Insurance Act to increase from $500 million to $1 billion the asset size of small insured depository institutions eligible for 18-month on-site examination cycles. Such an institution is also qualified for the 18-month cycle if its total assets are at most $200 million (currently $100 million) and the most recent examination found its composite condition to be good rather than outstanding. A federal banking agency is granted discretion to increase this assets ceiling amount from $200 million to $1 billion (currently from $100 million to $500 million) if that greater asset size would be consistent with the principles of safety and soundness.
