5.50% Senior Notes

In May 2015, the Company issued $500.0 million aggregate principal amount of 5.50% senior notes (the “5.50% Senior Notes”). The 5.50% Senior Notes mature on May 31, 2023, and bear interest at a rate of 5.50% per annum, payable semi-annually on May 15 and November 15, commencing on November 15, 2015. The Company received net proceeds of $488.4 million from the issuance of the 5.50% Senior Notes, net of issuance costs of $11.6 million which are being amortized to interest expense over the term of the 5.50% Senior Notes using the effective interest method. A portion of the proceeds was used to repay all then-outstanding amounts under our revolving line of credit agreement with Wells Fargo Bank and the remaining proceeds were used primarily for share repurchases.

The fair value of the 5.50% Senior Notes was determined based on inputs that were observable in the market, including the trading price of the 5.50% Senior Notes when available (Level 2). The estimated fair value and carrying value of the 5.50% Senior Notes were as follows:



	March 31, 2017				December 31, 2017
(in thousands)	Fair Value		Carrying Value		Fair Value		Carrying Value
5.50% Senior Notes	$	505,150	$	491,059	$	520,425	$	492,146

The Company may redeem all or a part of the 5.50% Senior Notes, upon not less than 30 or more than a 60 day notice; however, the applicable redemption price will be determined as follows:



	Redemption Period Requiring Payment of:		Redemption Up To 35% Using Cash Proceeds From An Equity Offering⁽³⁾:
	Make-Whole⁽¹⁾	Premium⁽²⁾	Date	Specified Price
5.50% Senior Notes	Prior to May 15, 2018	On or after May 15, 2018	Prior to May 15, 2018	105.500%

⁽¹⁾If the Company redeems the notes prior to the applicable date, the redemption price is principal plus a make-whole premium equal to the present value of the remaining scheduled interest payments as described in the applicable indenture, together with accrued and unpaid interest.

⁽²⁾If the Company redeems the notes on or after the applicable date, the price is principal plus a premium which declines over time as specified in the applicable indenture, together with accrued and unpaid interest.

⁽³⁾If the Company redeems the notes prior to the applicable date with net cash proceeds of one or more equity offerings, the price is equal to the amount specified above, together with accrued and unpaid interest, subject to a maximum redemption of 35% of the aggregate principal amount of the respective note being redeemed.

In addition, upon the occurrence of certain change of control triggering events, the Company may be required to repurchase the 5.50% Senior Notes, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase. The 5.50% Senior Notes contain restrictive covenants that, among other things, limit the Company's ability to create certain liens and enter into sale and leaseback transactions; create, assume, incur, or guarantee additional indebtedness of its subsidiaries without such subsidiary guaranteeing the 5.50% Senior Notes on an unsecured unsubordinated basis; and consolidate or merge with, or convey, transfer or lease all or substantially all of the assets of the Company and its subsidiaries to another person. As of December 31, 2017, the Company was in compliance with all covenants.

Revolving Credit Agreement

On May 9, 2011, the Company entered into a credit agreement with Wells Fargo Bank, National Association ("the Bank"), which was most recently amended on April 28, 2017 (as amended, the "Amended Credit Agreement") to extend the term of the Credit Agreement by one year to May 9, 2020, and to amend certain of the covenants, which are defined below.

The Amended Credit Agreement provides for a $100.0 million unsecured revolving credit facility. Revolving loans under the Credit Agreement will bear interest, at the Company’s election, at (i) the Bank’s announced prime rate less 1.20% per annum or (ii) a daily one-month LIBOR rate plus 1.40% per annum. Interest is payable quarterly in arrears on the first day of each of April, July, October and January. Principal, together with all accrued and unpaid interest, on the revolving loans is due and payable on May 9, 2020. The Company is also obligated to pay a commitment fee of 0.37% per annum on the average daily unused amount of the revolving line of credit, which fee shall be payable quarterly in arrears on the first day of each of April, July, October and January.

The Company may prepay the loans and terminate the commitments under the Credit Agreement at any time, without premium or penalty, subject to the reimbursement of certain costs. During the three months ended December 31, 2017 the Company borrowed and repaid $8 million from our line of credit, and as of March 31, 2017 and December 31, 2017, the Company had no outstanding borrowings on the line of credit.

The Amended Credit Agreement contains customary affirmative and negative covenants, including, among other things, covenants limiting the ability of the Company to incur debt, make capital expenditures, grant liens, merge or consolidate, and make investments. The Amended Credit Agreement also requires the Company to comply with certain financial covenants, including (i) a maximum ratio of funded debt to EBITDA of 3.25:1 (previously 3:1) and (ii) a minimum EBITDA coverage ratio, in each case, tested as of each fiscal quarter and determined on a rolling four-quarter basis. In addition, the Company and its subsidiaries are required to maintain unrestricted cash, cash equivalents and marketable securities plus availability under the Amended Credit Agreement at the end of each fiscal quarter of at least $300.0 million. The Amended Credit Agreement contains customary events of default that include, among other things, payment defaults, covenant defaults, cross-defaults with certain other indebtedness, bankruptcy and insolvency defaults, and judgment defaults. The occurrence of an event of default could result in the acceleration of the obligations under the Amended Credit Agreement. As of March 31, 2017 and December 31, 2017, the Company was in compliance with all covenants.
