At March 31, 2012, fixed rate loans accounted for 39% of the loan portfolio, compared with 46% at March 31, 2011, reflecting the Company's focus on variable rate commercial lending. The weighted average yield on the variable rate and fixed rate loan portfolios (excluding loan discount accretion) at March 31, 2012 was 4.61% and 6.49%, respectively, compared with 4.82% and 7.12% at March 31, 2011.The weighted average yield on securities available for sale for first quarter 2012 was 2.71%, compared with 2.99% for first quarter 2011 and 2.65% for fourth quarter 2011. The improvement in yield for the first quarter of 2012 over the prior quarter was due to slower prepayment speeds within the portfolio, which reduced the negative impact of premium amortization. The decline in yield from first quarter 2011 was the result of the replacement of maturing securities with lower yield investments as market interest rates declined and the impact of acquisition accounting.
