The FDIC is amending its regulations to revise the ratios and ratio thresholds for capital evaluations used in its risk-based deposit insurance assessment system to conform to the prompt corrective action capital (PCA) ratios and ratio thresholds adopted by the FDIC, the Board of Governors of the Federal Reserve System (Federal Reserve) and the Office of the Comptroller of the Currency (OCC) (collectively, the Federal banking agencies); revise the assessment base calculation for custodial banks to conform to the asset risk weights adopted by the Federal banking agencies; and require all highly complex institutions to measure counterparty exposure for deposit insurance assessment purposes using the Basel III standardized approach credit equivalent amount for derivatives (with modifications for certain cash collateral) and the Basel III standardized approach exposure amount for securities financing transactions--such as repo-style transactions, margin loans and similar transactions--as adopted by the Federal banking agencies.
