Debt covenants, description |  |  |  |  |  |  | The Senior Credit Facility, as amended, is subject to customary affirmative, negative and financial covenants. As of January 31, 2013, these covenants restrict fiscal year capital expenditures to 1.5 times our consolidated depreciation expenses, depletion expenses and landfill amortization expenses, set a minimum interest coverage ratio of 2.00, a maximum consolidated total funded debt to consolidated EBITDA ratio of 5.75 and a maximum senior funded debt to consolidated EBITDA ratio of 2.75. In addition to the financial covenants described above, the Senior Credit Facility, as amended, also contains a number of important negative covenants which restrict, among other things, our ability to sell assets, pay dividends, repurchase stock, incur debt, grant liens and issue preferred stock. As of January 31, 2013, we were in compliance with all covenants under the indenture governing the Senior Credit Facility and we do not believe that these restrictions impact our ability to meet future liquidity needs except that they may impact our ability to increase our investments in third parties, including the joint ventures to which we are already party to. |  |  |  |  |  |  |  |
