In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in the financial statements. These costs are now presented as a direct deduction from the debt liability, rather than as an asset. We adopted the new standard effective January 1, 2016. As a result, we reclassified unamortized debt issuances cost in the amount of $3.7 million and $4.0 million as of March 31, 2016 and December 31, 2015, respectively, and reduced the carrying value of long-term debt by the same amounts. Our 5.25% Senior Notes (the “2019 Notes”) will mature on March 15, 2019, are unconditionally guaranteed on a senior basis by the each of PHI’s domestic subsidiaries, and are the general, unsecured obligations of PHI and the guarantors. Interest is payable semi-annually on March 15 and September 15 of each year. PHI has the option to redeem some or all of the 2019 Notes at any time on or after March 15, 2016 at specified redemption prices. Prior to that time, PHI has the option to redeem some or all of the 2019 Notes pursuant to certain “make-whole” provisions or to redeem a portion of the 2019 Notes with the net proceeds of certain specified equity offerings. The indenture governing the 2019 Notes (the “2019 Indenture”) contains, among other things, certain restrictive covenants, including limitations on incurring indebtedness, creating liens, selling assets and entering into certain transactions with affiliates. The covenants also limit PHI’s ability to, among other things, pay cash dividends on common stock, repurchase or redeem common or preferred equity, prepay subordinated debt and make certain investments. Upon the occurrence of a “Change in Control Repurchase Event” (as defined in the 2019 Indenture), PHI will be required, unless it has previously elected to redeem the 2019 Notes as described above, to make an offer to purchase the 2019 Notes for a cash price equal to 101% of their principal amount. Revolving Credit Facility – We have an amended and restated revolving credit facility that matures on October 1, 2017. Under this facility, we can borrow up to $150 million at floating interest rates based on either the London Interbank Offered Rate plus 225 basis points or the prime rate (each as defined in our amended and restated revolving credit facility), at our option. Our revolving credit facility includes usual and customary covenants and events of default for credit facilities of its type. Our ability to borrow under the credit facility is conditioned upon our continued compliance with such covenants, including, among others, (i) covenants that restrict our ability to engage in certain asset sales, mergers or other fundamental changes, to incur liens or to engage in certain other transactions or activities and (ii) financial covenants that stipulate that PHI will maintain a consolidated working capital ratio of at least 2 to 1, a funded debt to consolidated net worth ratio not greater than 1.5 to 1, a fixed charge coverage ratio of at least 1.1 to 1, and consolidated net worth of at least $450 million (with all such terms or amounts as defined in or determined under the amended and restated revolving credit facility). As of March 31, 2016, we believe we were in compliance with these covenants. Cash paid to fund interest expense was $13.7 million for the quarter ended March 31, 2016 and $13.5 million for the quarter ended March 31, 2015. Other – We maintain a separate letter of credit facility that had $15.3 million in letters of credit outstanding at March 31, 2016 and December 31, 2015. We have letters of credit securing our workers compensation policies and a traditional provider contract.
