a. Credit Facility

On June 14, 2013, the Company amended its revolving credit agreement to adjust the interest rate spreads and extend the maturity date by one year. The revolving credit agreement, as amended, permits the Company to borrow up to $475,000,000 at an interest rate equal to, at the Company’s option, the base rate plus 0.25% to 1.00% or LIBOR plus 1.25% to 2.00%, or a combination thereof; provides for a fee of 0.25% to 0.40% of unused commitments; and contains certain covenants relating to the ratio of debt to operating performance measurements, interest coverage ratios and minimum net worth. Borrowings under the revolving credit agreement mature in June 2018 and are secured primarily by a pledge of the stock of the Company’s wholly-owned subsidiaries and the Company’s partnership and membership interests in the LPs and LLCs. The Company was in compliance with the covenants contained in the revolving credit agreement at June 30, 2014.

The 2020 Senior Unsecured Notes are general unsecured obligations of the Company and are guaranteed by its existing and subsequently acquired or organized wholly-owned domestic subsidiaries. The 2020 Senior Unsecured Notes are pari passu in right of payment with all the existing and future senior debt of the Company and senior to all existing and future subordinated debt of the Company.

On or after November 30, 2015, the Company may redeem the 2020 Senior Unsecured Notes in whole or in part. The redemption price for such a redemption (expressed as percentages of principal amount) is set forth below, plus accrued and unpaid interest and liquidated damages, if any, if redeemed during the twelve-month period beginning on November 30 of the years indicated below:
