Credit Facilities

On December 19, 2014, the Company entered into a Fourth Amended and Restated Credit Agreement with General Electric Capital Corporation (which has since assigned its interest to Capital One Financial Corporation), as administrative agent, lender and swingline lender, and the other lenders from time to time parties thereto. The agreement currently provides for a total commitment amount of $400.0 million, comprised of a $400.0 million revolving credit facility (with a $50.0 million sublimit for letters of credit and a $50.0 million swingline feature to permit same day borrowing) and an option to increase the revolving credit facility by an additional $250.0 million, subject to obtaining commitments for the amount of such increase from acceptable lenders. The maturity date is January 3, 2020, and amounts drawn under the facility bear interest at 90-day LIBOR plus an applicable margin from a range of 2.50% to 3.50%. The applicable margin varies based on the percentage of the total commitment drawn, with a 2.50% margin at utilization equal to or lower than 35%, a 3.25% margin at utilization greater than 35% but less than or equal to 50%, and a 3.50% margin at utilization greater than 50%. The quarterly commitment fee on the unused portion of the facility is 0.25% per annum when the outstanding amount of obligations (including revolving credit, swingline and term loans and letter of credit obligations) is greater than or equal to 50% of the total commitment amount or 0.35% per annum when such outstanding amount is less than 50% of the total commitment amount.

Amounts drawn on the facility may be used to finance acquisitions, 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. In addition, the agreement permits the Company to pledge the equity interests in subsidiaries that own other communities (rather than mortgaging such communities), provided that loan availability from pledged assets cannot exceed 10% of loan availability from mortgaged assets. 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 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 credit agreement, which would result in termination of all commitments under the agreement and all amounts owing under the agreement becoming immediately due and payable and/or could trigger cross default provisions in our other outstanding debt and lease agreements.

As of September 30, 2017, no borrowings were outstanding on the revolving credit facility and $38.5 million of letters of credit were outstanding under this credit facility. The Company also had separate letter of credit facilities of up to $64.5 million in the aggregate as of September 30, 2017. Letters of credit totaling $64.4 million had been issued under these separate facilities as of September 30, 2017.

2017 Financings

In June 2017, the Company obtained a $54.7 million non-recourse addition and borrow-up loan, secured by first mortgages on seven communities. The loan bears interest at a fixed rate of 4.69% and matures on March 1, 2022. Proceeds from the loan added to the Company's liquidity.

In July 2017, the Company completed the refinancing of two existing loan portfolios secured by the non-recourse first mortgages on 22 communities. The $221.3 million of proceeds from the refinancing were primarily utilized to repay $188.1 million and $13.6 million of mortgage debt maturing in April 2018 and January 2021, respectively. The mortgage facility has a 10 year term, and 70% of the principal amount bears interest at a fixed rate of 4.81% and the remaining 30% of the principal amount bears interest at a variable rate of 30-day LIBOR plus a margin of 244 basis points.

In August 2017, the Company obtained $975.0 million of debt secured by the non-recourse first mortgages on 51 communities. Sixty percent of the principal amount bears interest at a fixed rate, with one half of such amount bearing interest at 4.43% and maturing in 2024 and the other one half bearing interest at 4.47% and maturing in 2027. Forty percent of the principal amount bears interest at a variable rate equal to the 30-day LIBOR plus a margin of 241.5 basis points and matures in 2027. The $975.0 million of proceeds from the refinancing were primarily utilized to repay $389.9 million and $228.9 million of outstanding mortgage debt scheduled to mature in August 2018 and May 2023, respectively. The net proceeds from the refinancing activity added to the Company's liquidity.

The Company plans to repay debt maturing in the upcoming year, including the $316.3 million outstanding principal amount of convertible senior notes due June 15, 2018, through current liquidity, future operating cash flows, and normal-course refinancings.

Convertible Debt

In June 2011, the Company completed a registered offering of $316.3 million aggregate principal amount of 2.75% convertible senior notes due June 15, 2018 (the "Notes"). As of September 30, 2017, the $306.1 million carrying value of the Notes was included in the current portion of long-term debt within the condensed consolidated balance sheet. It is the Company’s current intent and policy to settle the principal amount of the Notes (or, if less, the amount of the conversion obligation) in cash upon conversion.

As of September 30, 2017, the Company is in compliance with the financial covenants of its outstanding debt and lease agreements.
