On December 22, 2006, the Company entered into a Master Shelf and Note Purchase Agreement (the “Master Agreement”) with a national insurance company (the “Purchaser”). The initial issuance of notes under the Master Agreement occurred on December 22, 2006, through the issuance of $25.0 million in Series C Senior Notes due December 22, 2016, with a fixed interest rate of 5.660% per year. On February 1, 2008, $25.0 million in Series D Senior Notes due January 15, 2015, with a fixed interest rate of 5.370% per year, were issued. On September 15, 2011, and pursuant to a Confirmation of Acceptance (the “Confirmation”), dated January 21, 2011, in connection with the Master Agreement, $100.0 million in Series E Senior Notes were issued and are due September 15, 2018, with a fixed interest rate of 4.500% per year. The Series E Senior Notes were issued for the sole purpose of retiring existing senior notes. On January 15, 2015 the Series D Senior Notes were redeemed at maturity using cash proceeds to pay off the principal of $25.0 million plus any remaining accrued interest. On December 22, 2016, the Series C Senior Notes were redeemed at maturity using cash proceeds to pay off the principal of $25.0 million plus any remaining accrued interest. As of March 31, 2017, there was an outstanding debt balance issued under the provisions of the Master Agreement of $100.0 million.

On April 17, 2014, the Company entered into a credit agreement with JPMorgan Chase Bank, N.A. as administrative agent and certain other banks as co-syndication agents and co-documentation agents (the “Credit Agreement”). The Credit Agreement in the amount of $1,350.0 million provides for an unsecured revolving credit facility (the “Credit Facility”) in the initial amount of $800.0 million and unsecured term loans in the initial amount of $550.0 million, either or both of which may, subject to lenders’ discretion, potentially be increased by up to $500.0 million. The Credit Facility was funded on May 20, 2014 in conjunction with the closing of the Wright acquisition, with the $550.0 million term loan being funded as well as a drawdown of $375.0 million on the revolving loan facility. Use of these proceeds was to retire existing term loan debt and to facilitate the closing of the Wright acquisition as well as other acquisitions. The Credit Facility terminates on May 20, 2019, but either or both of the revolving Credit Facility and the term loans may be extended for two additional one-year periods at the Company’s request and at the discretion of the respective lenders. Interest and facility fees in respect to the Credit Facility are based on the better of the Company’s net debt leverage ratio or a non-credit enhanced senior unsecured long-term debt rating. Based on the Company’s net debt leverage ratio, the rates of interest charged on the term loan are 1.000% to 1.750%, and the revolving loan is 0.850% to 1.500% above the adjusted LIBOR rate for outstanding amounts drawn. There are fees included in the facility which include a facility fee based on the revolving credit commitments of the lenders (whether used or unused) at a rate of 0.150% to 0.250% and letter of credit fees based on the amounts of outstanding secured or unsecured letters of credit. The Credit Facility includes various covenants, limitations and events of default customary for similar facilities for similarly rated borrowers. As of March 31, 2017 and December 31, 2016, there was an outstanding debt balance issued under the provisions of the Credit Facility in total of $467.5 million and $481.3 million respectively, with no borrowings outstanding relative to the revolving loan. Per the terms of the agreement, a scheduled principal payment of $13.8 million is due on June 30, 2017.

On September 18, 2014, the Company issued $500.0 million of 4.200% unsecured senior notes due in 2024. The senior notes were given investment grade ratings of BBB-/Baa3 with a stable outlook. The notes are subject to certain covenant restrictions and regulations which are customary for credit rated obligations. At the time of funding, the proceeds were offered at a discount of the original note amount which also excluded an underwriting fee discount. The net proceeds received from the issuance were used to repay the outstanding balance of $475.0 million on the revolving Credit Facility and for other general corporate purposes. As of March 31, 2017 and December 31, 2016, there was an outstanding debt balance of $500.0 million exclusive of the associated discount balance.

In conjunction with the acquisition of Social Security Advocates for the Disabled (SSAD) effective February 1, 2016, the company added a $0.5 million promissory note incurred as a payment to the sellers and payable after the one-year anniversary of the acquisition. The note had a nominal rate of interest 0.810%. On March 10, 2017, the promissory note was settled, plus any outstanding accrued interest, using cash.

The Master Agreement and the Credit Agreement all require the Company to maintain certain financial ratios and comply with certain other covenants. The Company was in compliance with all such covenants as of March 31, 2017 and December 31, 2016.

The 30-day Adjusted LIBOR Rate as of March 31, 2017 was 1.000%.
