This excerpt taken from the PNC 10-Q filed May 11, 2009.
As previously disclosed in our 2008 Form 10-K, on December 31, 2008, we issued $7.6 billion of Fixed Rate Cumulative Perpetual Preferred Stock, Series N, to the US Treasury under the US Treasurys Trouble Asset Relief Program (TARP) Capital Purchase Program, together with a warrant to purchase shares of common stock of PNC.
The proceeds from the issuance of the preferred stock to the US Treasury were allocated based on the relative fair value of the warrant as compared to the fair value of the preferred stock. The fair value of the warrant was determined using a Black-Scholes valuation model. The model incorporates assumptions regarding our common stock price, dividend yield, stock price volatility, as well as assumptions regarding the risk-free interest rate. Using this model, the warrant was valued at $304 million at December 31, 2008 and was included in Capital surplus common stock and other on our Consolidated Balance Sheet.
The fair value of the preferred stock was determined based on assumptions regarding the discount rate (market rate) on the preferred stock, which was estimated to be approximately 13%. The discount on the preferred stock is being accreted to par value using a constant effective yield of 6% over a five-year period, which was the expected life of the preferred stock at issuance. The accretion of discount on these shares increased Capital surplus preferred stock and reduced Retained earnings on our Consolidated Balance Sheet by approximately $13.5 million at March 31, 2009.
