The weighted average yield on securities available for sale is summarized in the following table:
|Three Months Ended|
|Weighted average yield on securities available-for-sale||2.08||%||2.65||%||(0.57||)%||2.23||%||(0.15||)%|
The weighted average yield on securities available-for-sale for fourth quarter 2012 declined 57 basis points from fourth quarter 2011 and 15 basis points from the preceding third quarter 2012. The reductions are primarily attributable to the replacement of maturing securities with lower yielding investments as market interest rates declined.
