capital resources in december 2008 , we filed a shelf registration statement with the securities and exchange commission under which $ 760 million in debt securities may be issued .

based on our current long-term senior unsecured debt ratings of a+ and a1 from standard and poor 2019s corporation and moody 2019s investor services , respectively , the interest rate charged on any outstanding borrowings would be the prevailing london interbank offer rate ( 201clibor 201d ) plus 0.15% ( 0.15 % ) .
the facility fee is 0.05% ( 0.05 % ) of the total commitment .
if our long-term debt rating were to decline , the facility fee and interest rate under our committed credit facility would increase .
conversely , if our long-term debt rating were to improve , the facility fee and interest rate would decrease .
changes in our long-term debt rating would not trigger acceleration of maturity of any then outstanding borrowings or any future borrowings under the committed credit facility .
under this committed credit facility , we have agreed to various covenants .
these covenants include limits on our disposal of fixed assets and the amount of debt secured by liens we may incur as well as a minimum capitalization ratio .
