Revolving Credit Agreement

On May 19, 2015, the Company entered into a $150.0 million four-year unsecured revolving credit agreement with KeyBank National Association, as administrative agent (the "Agent"), and the lenders from time to time party thereto. On May 19, 2015, the Company made an initial drawing of $100.0 million under the Revolving Credit Agreement, resulting in $50.0 million available for additional borrowings. On October 13, 2017, the Company entered into an amendment and restatement agreement (the "Amendment Agreement") with respect to its revolving credit agreement (as amended by the Amendment Agreement, the "Revolving Credit Agreement"). The Amendment Agreement, among other things, increased the total commitments available under the revolving credit facility from $150.0 million to $250.0 million, increased the aggregate amount of additional incremental loans the Company may incur from $50.0 million to $100.0 million and extended the maturity date of the revolving credit facility from May 19, 2019 to the earlier of October 13, 2022 and the date that is six months prior to the maturity date of the 2020 Notes, which is November 30, 2019.

The interest rates with respect to loans under the Revolving Credit Agreement are based on, at the Company's option, a floating base rate (defined as a per annum rate equal to the highest of: (i) the federal funds rate plus 0.50%; (ii) the "prime rate" of the Agent; and (iii) the eurodollar rate for a one-month interest period plus an applicable margin based on the Company's unsecured debt rating), or a eurodollar rate plus an applicable margin based on the Company's unsecured debt rating. The margins under the Revolving Credit Agreement range from 1.375% to 2.125%, in the case of loans at the eurodollar rate, and 0.375% to 1.125%, in the case of loans at the base rate. At March 31, 2018, the interest rate on the amounts outstanding under the Revolving Credit Agreement was 3.75 percent. In addition, the daily average undrawn portion of the Revolving Credit Agreement accrues a commitment fee payable quarterly in arrears. The applicable margin for, and the commitment fee applicable to, the Revolving Credit Agreement, will be adjusted from time to time pursuant to a ratings based pricing grid.

The Revolving Credit Agreement requires the Company to maintain (each as calculated in accordance with the Revolving Credit Agreement): (i) a debt to total capitalization ratio of not more than 35.0 percent (such ratio was 20.1 percent at March 31, 2018); (ii) an aggregate ratio of total adjusted capital to company action level risk-based capital for the Company's insurance subsidiaries of not less than 250 percent (such ratio was estimated to be 427 percent at March 31, 2018); and (iii) a minimum consolidated net worth of not less than the sum of (x) $2,674 million plus (y) 50.0% of the net equity proceeds received by the Company from the issuance and sale of equity interests in the Company (the Company's consolidated net worth was $3,722.9 million at March 31, 2018 compared to the minimum requirement of $2,685.7 million).
