At December 31, 2012, we had $26.0 million of overnight borrowings with the FHLB at a cost of 12 basis points.

At December 31, 2012, $2.32 billion of loans and $2.24 billion of investment securities, at carrying value, were pledged to secure public deposits, short and long-term borrowings, and for other purposes as required or permitted by law.

In November 2006, we began a repurchase agreement product with our customers. This product, known as Citizens Sweep Manager, sells our securities overnight to our customers under an agreement to repurchase them the next day. As of December 31, 2012 and 2011, total funds borrowed under these agreements were $473.2 million and $509.4 million, respectively, with weighted average interest rates of 0.28% and 0.35%.
