Convertible Senior Notes

In July 2009, the Company issued $172.5 million aggregate principal amount of 5.0% convertible senior notes which were settled in July 2014. The notes were unsecured, senior obligations of the Company and interest was payable semi-annually in arrears on January 15 and July 15 of each year.

At the time of issuance, the Company had the choice of net-cash settlement, settlement in its own shares or a combination thereof and concluded the conversion option was indexed to its own stock. As a result, the Company allocated $24.7 million of the $172.5 million principal amount of the convertible senior notes to equity, resulting in a debt discount. The debt discount was amortized as additional non-cash interest expense over the period the convertible senior notes were outstanding. At June 30, 2014, the remaining unamortized discount was $0.3 million. The combined debt discount amortization and the contractual interest coupon resulted in an effective interest rate on the convertible debt of 8.9%.

The following table provides interest rate and interest expense amounts related to the convertible senior notes:

Senior Term Notes

In November 2013, the Company issued $120.0 million aggregate principal amount of 5.75% senior unsecured notes due December 2017 (Senior Term Notes). Net proceeds from the issuance of the Senior Term Notes were $118.1 million. Interest on the Senior Term Notes is payable semi-annually in arrears on June 1 and December 1 of each year, beginning on June 1, 2014. The Senior Term Notes rank equally with the Company's existing senior unsecured debt. The Senior Term Notes are unsecured and not guaranteed by any of the Company's subsidiaries or any third party.

The Senior Term Notes contain maintenance covenants, including limitations on incurrence of debt, granting of liens, investments, merger or consolidation, certain restricted payments and transactions with affiliates, none of which are more restrictive than those under the Company’s revolving credit facility.

Revolving Credit Facility

The Company has a $400.0 million unsecured revolving credit facility that expires in June 2018. The revolving credit facility has rates tied to a LIBOR credit spread and a quarterly facility fee on the average daily amount of the facility (whether used or unused). Both the LIBOR credit spread and the facility fee are based on the Company's debt to EBITDA ratio at the end of each fiscal quarter. In addition, the Company may request an increase in revolving credit commitments under the facility of up to $200.0 million under certain circumstances. Events of default under the credit agreement include change of control of the Company and the Company's default with respect to other debt exceeding $10.0 million. As of June 30, 2015 and 2014, the Company had no outstanding borrowings under this revolving credit facility. Additionally, the Company had outstanding standby letters of credit under the revolving credit facility of $2.1 and $2.2 million at June 30, 2015 and 2014, respectively, primarily related to its self-insurance program. Unused available credit under the facility at June 30, 2015 and 2014 was $397.9 and $397.8 million, respectively.

Equipment and Leasehold Notes Payable

The equipment and leasehold notes payable are primarily comprised of capital lease obligations. As of June 30, 2015 and 2014, the capital lease balance was $0.0 and $1.3 million.
