Credit Facilities

On March 28, 2013, the Company entered into a second amended and restated credit agreement with General Electric Capital Corporation, as administrative agent and lender, and the other lenders from time to time parties thereto. The amended credit agreement extended the maturity date of the facility to March 31, 2018 and decreased the interest rate payable on advances and the fee payable on the unused portion of the facility. The amended credit agreement provided an option to increase the committed amount initially from $230.0 million to $250.0 million, which the Company exercised on June 28, 2013, and provides an additional option to increase the committed amount from $250.0 million to up to $350.0 million, subject to obtaining commitments for the amount of such increase from acceptable lenders. The amended credit agreement also permits reduction of the committed amount or termination of the facility during the last two years of the five year term without payment of a premium or penalty. The amended credit agreement was further amended and restated effective September 20, 2013 to, among other things, incorporate a $25.0 million swingline feature to permit same-day borrowing.

Amounts drawn under the facility bear interest at 90-day LIBOR plus an applicable margin. The applicable margin varies with the percentage of the total commitment drawn, with a 3.25% margin at 25% or lower utilization, a 3.75% margin at utilization greater than 25% but less than or equal to 50%, and a 4.25% margin at greater than 50% utilization. For purposes of determining the interest rate, in no event will LIBOR be less than 0.5% per annum. The Company is also required to pay a quarterly commitment fee of 0.5% per annum on the unused portion of the facility.

The revolving line of credit can be used to finance acquisitions and fund working capital and capital expenditures and for other general corporate purposes.

The facility is secured by a first priority mortgage on certain of the Company's communities. The availability under the line will vary from time to time as it is based on borrowing base calculations related to the appraised value and performance of the communities securing the facility.

The amended credit agreement contains typical affirmative and negative covenants, including financial covenants with respect to minimum consolidated fixed charge coverage and minimum consolidated tangible net worth. A violation of any of these covenants could result in a default under the amended credit agreement, which would result in termination of all commitments under the amended credit agreement and all amounts owing under the amended credit agreement and certain other loan agreements becoming immediately due and payable.

As of June 30, 2014, the Company had an available secured line of credit with a commitment and available amount of $250.0 million (of which $12.0 million had been drawn as of such date). The Company also had secured and unsecured letter of credit facilities of up to $84.5 million in the aggregate as of June 30, 2014. Letters of credit totaling $71.6 million had been issued under these facilities as of that date.

Financings

On April 9, 2014, the Company obtained $146.0 million in loans, secured by first mortgages on 20 communities. The loans bear interest at a fixed rate of 4.77% and mature in May 2021. Proceeds of the loans were used to refinance $140.0 million of mortgage debt that was scheduled to mature in November 2014.

As of June 30, 2014, the Company is in compliance with the financial covenants of its outstanding debt and lease agreements.
