PREFERRED STOCK On December 12, 2008, Old National announced that it had entered into an agreement to sell Series T Preferred Stock having a liquidation value of $100 million to the Treasury Department as part of the CPP for healthy financial institutions announced in late October 2008. As part of the CPP, Old National entered into a Letter Agreement and Securities Purchase Agreement with the Treasury Department on December 12, 2008, pursuant to which Old National sold (i) 100,000 shares of Old National's Series T Preferred Stock and (ii) Warrants to purchase up to 813,008 shares of Old National's common stock at an initial per share exercise price of $18.45. The net proceeds were allocated between the Series T Preferred Stock and Warrants based on relative fair value. The Series T Preferred Stock would be accreted to liquidation value over the expected life of the shares, with accretion charged to retained earnings. The Series T Preferred Stock qualified as Tier 1 capital and the Treasury Department was entitled to cumulative dividends at a rate of 5% per year for the first five years, and 9% per year thereafter. The Series T Preferred Stock had priority in the payment of dividends over any cash dividends paid to common stockholders. The adoption of ARRA permitted Old National to redeem the Series T Preferred Stock without penalty and without the need to raise new capital, subject to the Treasury's consultation with Old National's regulatory agency. On March 31, 2009, Old National accelerated the accretion of the $2.6 million discount and repurchased all of the $100 million of Series T Preferred Stock from the Treasury Department. The Warrants had a 10-year term and were immediately exercisable upon issuance. The Warrants were repurchased by Old National on May 11, 2009, for $1.2 million. As a result of the Warrant repurchase, the Treasury Department does not own any securities of Old National. COMMON STOCK The December 31, 2011 balance includes approximately $90.1 million from the approximately 7.6 million shares of common stock that were issued in the acquisition of Monroe Bancorp on January 1, 2011.
