Indebtedness	7. Indebtedness On August 31, 2010, the Company entered into an agreement to complete a $190.0 million private placement of senior unsecured notes that were issued and sold in two tranches: $95.0 million bearing interest at 5.0% and maturing January 13, 2018, Series A, and $95.0 million bearing interest of 5.75% and maturing January 13, 2021, Series B (collectively, the "Senior Notes"). The agreement contained a delayed funding provision that allowed the Company to draw down the proceeds in January 2011 when the 5.6% senior notes (the "Notes") matured. The Company used the proceeds of the issuance and sale of the Senior Notes to repay the Notes in full. Interest is payable semi-annually in January and July of each year. The most restrictive provisions of the agreement require the Company to maintain a consolidated leverage ratio not to exceed 3.0 to 1.0 for four consecutive quarters and a consolidated interest coverage ratio of not less than 4.0 to 1.0 for four consecutive quarters. The Company was in compliance with these covenants for all periods presented. As of December 31, 2015, the Company's consolidated leverage ratio was 0.4 to 1.0, and consolidated interest coverage ratio was 42.9 to 1.0. The Company entered into a five year revolving credit facility (the "Credit Facility") with various lenders, effective June 28, 2013, which provides for initial borrowings of up to $125.0 million and replaced the Company's previous revolving credit facility. Lenders could, at their option upon the Company's request, expand the Credit Facility to $200.0 million. At December 31, 2015 and 2014, there were no borrowings outstanding under the facility. Borrowings under the Credit Facility bear interest at various rates including adjusted LIBOR or an alternative base rate plus, in each case, an incremental margin based on the Company's credit rating. The Credit Facility also provides for a facility fee on the aggregate amount of commitments under the revolving facility (whether or not utilized). The facility fee is also based on the Company's credit rating level. The Credit Facility's covenants match those outlined above for the Senior Notes. Debt is reported at its carrying amount in the consolidated balance sheets. The fair value of the Company's outstanding indebtedness is approximately $202.5 million at December 31, 2015 compared to the carrying value of $190.0 million. Fair value is calculated based on Level 2 inputs.
