Fiserv, a provider of financial services technology solutions, announced today that Bank Ayudhya Public Company Limited (BAY) has selected KRM from Fiserv to help the Thailand-based institution develop internal ratings based models for its corporate and small/medium enterprise businesses.

Used to manage credit risk, liquidity risk and interest-rate risk, KRM incorporates advanced risk concepts developed by Robert A. Jarrow, an originator of the Heath-Jarrow-Morton multi-factor term structure model.

The probability of default (PD) results and ratings developed as part of this project eventually will be embedded into the bank’s credit approval process. KRM’s output from this project is considered to be one of the most crucial components of the bank’s credit risk management strategy.

“KRM’s full multi-period, macro-factor driven simulation will help the bank’s credit risk managers better estimate default probabilities as they rise and fall with the economy,” said Clement Ooi, vice president and managing director of Asia-Pacific operations for Risk and Performance Solutions, Fiserv.
