The New Credit Agreement provides for a $50,000 four-year unsecured revolving credit facility that includes a $20,000 letter of credit subfacility and a swingline subfacility in the amount up to $5,000.

The unused commitments under the New Credit Agreement will be subject to a commitment fee that will be calculated at a per annum rate. The applicable margins for borrowings under the New Credit Agreement and the commitment fee thereunder will be determined by reference to a pricing grid based on the Company’s issuer credit rating by A.M. Best Company, Inc. The New Credit Agreement contains customary representations, conditions to borrowing, covenants and events of default, including certain covenants that limit or restrict, subject to certain exceptions, the ability of the Company and its subsidiaries to sell or transfer assets, enter into a merger or consolidate with another company, create liens, impose restrictions on subsidiary dividends, enter into sale-leaseback transactions, make investments or acquisitions, enter into certain reinsurance agreements, pay dividends during any period of default, enter into transactions with affiliates, change the nature of its business, or incur indebtedness. The New Credit Agreement also includes financial covenants that require the Company to (i) maintain a minimum consolidated net worth, (ii) maintain a minimum consolidated statutory surplus and (iii) not exceed a 0.35 to 1.0 debt to total capitalization ratio. Prior to December 22, 2015, the Company had a credit agreement (the "Previous Credit Agreement") with a syndicate of financial institutions as lenders. KeyBank National Association was the administrative agent, lead arranger, sole book runner, swingline lender, and letter of credit issuer, and Bankers Trust Company was the syndication agent. The Previous Credit Agreement provided for a $100,000 unsecured revolving credit facility that included a $20,000 letter of credit subfacility and a swingline subfacility of up to $5,000. The Previous Credit Agreement terminated by expiration on its stated termination date of December 22, 2015. There was no outstanding balance on either the New Credit Agreement or Previous Credit Agreement at June 30, 2016 and 2015. For the six-month periods ended June 30, 2016 and 2015, we did not incur any interest expense related to either credit facility. We were in compliance with all covenants of the New Credit Agreement at June 30, 2016.
