A note agreement and guaranty ("Prudential Agreement") was entered into in October 2005, and was amended and restated September 17, 2010 and 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. The Prudential Agreement provides for mandatory payments of $50 million on each of 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 Prudential Agreement contains customary terms, as well as affirmative covenants, negative covenants, and events of default comparable to those in our current principal credit facility (as described below). For disclosure purposes, we are required to measure the fair value of outstanding debt on a recurring basis. As of September 30, 2013, the fair value of the Prudential Agreement was approximately $167.7 million, which was measured using active market interest rates, which would be considered Level 2 for fair value measurement purposes.

On March 26, 2013, we entered into a $330 million, unsecured Five-Year Revolving Credit Facility Agreement ("Credit Agreement"), under which $152 million of borrowings were outstanding as of September 30, 2013. The Credit Agreement replaces the previous $390 million five-year Credit agreement made in 2010. The applicable interest rate for borrowings under the Credit Agreement, as well as under the former agreement, is LIBOR plus a spread, based on our leverage ratio at the time of borrowing. At the time of the last borrowing on September 23, 2013, the spread was 1.375%. The spread is based on a pricing grid, which ranges from 1.25% to 1.875%, based on our leverage ratio.

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 September 30, 2013 we would have been able to borrow an additional $178 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 Credit 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 July 16, 2013 was 0.27%. 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 September 30, 2013, the all-in rate on the $105 million of debt was 3.415%.

On May 20, 2013, we entered into interest rate hedging transactions for the period July 16, 2015 through March 16, 2018. These transactions have the effect of fixing the LIBOR portion of the effective interest rate (before addition of the spread) on $110 million of the indebtedness drawn under the Credit Agreement at the rate of 1.414% during this period. Under the terms of these transactions, we pay the fixed rate of 1.414% and the counterparties pay a floating rate based on the one-month LIBOR rate at each monthly calculation date, which on September 30, 2013 was 0.18%. The net effect is to fix the effective interest rate on $110 million of indebtedness at 1.414%, plus the applicable spread, during the swap period.

The interest rate swaps are accounted for as a hedge of future cash flows, as further described in Note 14 of the Notes to Consolidated Financial Statements. No cash collateral was received or pledged in relation to the swap agreements.

Under the Credit Agreement and Prudential Agreement, we are currently required to maintain a leverage ratio (as defined in the agreements) of not greater than 3.50 to 1.00 and minimum interest coverage (as defined) of 3.00 to 1.00.

As of September 30, 2013, our leverage ratio was 1.77 to 1.00 and our interest coverage ratio was 8.30 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 3.50 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 Credit agreement.

In connection with the original sale of the Notes in 2006, 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. These transactions had a net cost of $14.7 million. The hedge transactions expired on March 15, 2013 and all warrants were expired by September 10, 2013.

Indebtedness under each of the Prudential 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 September 30, 2013.
