Pimco’s information ratio during 2009 was 3.19, which represents its monthly return spread over the benchmark return divided by the standard deviation of returns over the 12 month period. Pimco’s Sharpe ratio for the four year return period was 1.08, which represents Pimco’s excess monthly returns over the risk free rate divided by the standard deviation of its monthly returns over the 48 month time period.
