TARP Repayment – Second Quarter 2012 • Park repurchased the $100 million of cumulative preferred shares from the U.S. Treasury on April 25, 2012. Total consideration paid of $101 million included accrued interest and unpaid dividends. The warrant associated with the preferred shares was repurchased on May 2, 2012 for $2.8 million.
