Mr. Rosenqvist, asset manager, holds a portfolio of SEK 200 million, which consists of BBB-rated bonds. Assume that the one-year probability of default is 4%, the recovery rate is 60%, and defaults are uncorrelated over years. What is the two-year cumulative expected credit loss on Mr. Rosenqvist’s portfolio?
