5.	LONG-TERM DEBT

Amendment of Senior Credit Facility

On June 25, 2013, we entered into a third amendment under our revolving credit and letter of credit facility due March 18, 2016 (“Senior Credit Facility”). This amendment adjusted our financial covenants, loosening our minimum interest coverage ratio and our maximum consolidated total funded debt to consolidated EBITDA ratio and reducing our maximum senior funded debt to consolidated EBITDA ratio and maximum allowed fiscal year capital expenditures. As of October 31, 2013, these covenants restrict fiscal year capital expenditures to 1.1 times our consolidated depreciation expense, depletion expense and landfill amortization expense, set a minimum interest coverage ratio of 2.25, a maximum consolidated total funded debt to consolidated EBITDA ratio of 5.85 and a maximum senior funded debt to consolidated EBITDA ratio of 2.50. In addition to the financial covenants described above, the Senior Credit Facility also contains a number of negative covenants, which restrict, among other things, our ability to sell assets, pay dividends, invest in non-wholly owned entities, repurchase stock, incur debt, grant liens and issue preferred stock. As of October 31, 2013, we were in compliance with all covenants under the indenture governing our Senior Credit Facility. We do not believe that these restrictions impact our ability to meet future liquidity needs, except that they may limit our ability to increase our investments in non-wholly owned entities (including the joint ventures to which we are already party).

Loss on Debt Extinguishment

In the three months ended October 31, 2012, we recorded a charge of $9,670 as a loss on debt extinguishment related to the refinancing of our $180,000 11% senior second lien notes due 2014 (“Second Lien Notes”). The loss on debt extinguishment consisted of a $1,667 non-cash write off of deferred financing costs, a $1,258 non-cash write off of the unamortized original issue discount and a $6,745 loss associated with the tender premium and other tender fees associated with the portion of the Second Lien Notes extinguished.
