The note agreement and guaranty ("the Prudential agreement") was entered into in October 2005 and was amended and restated September 17, 2010 and on March 26, 2013, with the Prudential Insurance Company of America, and certain other purchasers, in an aggregate principal amount of $150 million, with interest at 6.84% and a maturity date of October 25, 2017. There are mandatory payments of $50 million on October 25, 2013 and October 25, 2015. At the noteholders' election, certain prepayments may also be required in connection with certain asset dispositions or financings. The notes may not otherwise be prepaid without a premium, under certain market conditions. The note agreement contains customary terms, as well as affirmative covenants, negative covenants, and events of default comparable to those in our current principal credit facility. For disclosure purposes, we are required to measure the fair value of outstanding debt on a recurring basis. As of March 31, 2013, the fair value of the note agreement was approximately $170.6 million, which was measured using active market interest rates. On March 26, 2013, we entered into a $330 million, unsecured Five-Year Revolving Credit Facility Agreement (the "New Agreement"), under which $176 million of borrowings were outstanding as of March 31, 2013. The New Agreement replaces the previous $390 million five-year facility agreement made in 2010. The applicable interest rate for borrowings under the 2013 agreement, as well as under the former agreement, is LIBOR plus a spread, based on our leverage ratio at the time of borrowing. Our ability to borrow additional amounts under the credit agreement is conditional upon the absence of any defaults, as well as the absence of any material adverse change. Based on our maximum leverage ratio and our consolidated EBITDA (as defined in the credit agreement), and without modification to any other credit agreements, as of March 31, 2013 we would have been able to borrow an additional $154 million under the credit agreement. On July 16, 2010, we entered into interest rate hedging transactions that have the effect of fixing the LIBOR portion of the effective interest rate (before addition of the spread) on $105 million of the indebtedness drawn under the New Agreement at the rate of 2.04% for five years. Under the terms of these transactions, we pay the fixed rate of 2.04% and the counterparties pay a floating rate based on the three-month LIBOR rate at each quarterly calculation date, which on January 16, 2013 was 0.31%. The net effect is to fix the effective interest rate on $105 million of indebtedness at 2.04%, plus the applicable spread, until these swap agreements expire on July 16, 2015. As of March 31, 2013, the all-in rate on this $105 million of debt was 3.415%. This interest rate swap is accounted for as a hedge of future cash flows, as further described in Note 14 of the Notes to Consolidated Financial Statements. We are currently required to maintain a leverage ratio of not greater than 3.50 to 1.00 and a minimum interest coverage of 3.00 to 1.00 under the credit agreement and Prudential agreement. As of March 31, 2013, our leverage ratio was 1.36 to 1.00 and our interest coverage ratio was 11.16 to 1.00. We may purchase our Common Stock or pay dividends to the extent our leverage ratio remains at or below 3.50 to 1.00, and may make acquisitions with cash provided our leverage ratio would not exceed 3.00 to 1.00 after giving pro forma effect to the acquisition. On March 15, 2013, the Company redeemed, at 100 percent of par, all remaining 2.25% Convertible Senior Notes due 2026 (the "Notes"). The cash payments of $28.4 million were funded by increased borrowings under the Revolving Credit Facility. In connection with the sale of the Notes, we entered into hedge and warrant transactions with respect to our Class A common stock. These transactions were intended to reduce the potential dilution upon conversion of the Notes by providing us with the option, subject to certain exceptions, to acquire shares in an amount equal to the number of shares that we would be required to deliver upon conversion of the Notes. These transactions had the economic effect to the Company of increasing the conversion price of the Notes to $52.25 per share. The Notes hedge and warrant transactions had a net cost of $14.7 million. The hedge transactions expired on March 15, 2013. Pursuant to the warrant transactions, we sold a total of 4.1 million warrants, each exercisable to buy a single share of Class A common stock at an initial strike price of $52.25 per share. The warrants are American-style warrants (exercisable at any time), and expire over a period of sixty trading days beginning on June 15, 2013. If the warrants are exercised when they expire, we may choose either net cash or net share settlement. If the warrants are exercised before they expire, they must be net share settled. If we elect to net cash settle the warrants, we will pay cash in an amount equal to, for each exercise of warrants, (i) the number of warrants exercised multiplied by (ii) the excess of the volume weighted average price of our Class A common stock on the expiration date of such warrants (the "settlement price") over the strike price. Under net share settlement, we will deliver to the warrant holders a number of shares of our Class A common stock equal to, for each exercise of warrants, the amount payable upon net cash settlement divided by the settlement price. Indebtedness under the Prudential note and guaranty agreement and the credit agreement is ranked equally in right of payment to all unsecured senior debt. We were in compliance with all debt covenants as of March 31, 2013.
