During 2005 and 2006, we took several steps to improve our capital structure. These transactions enabled us to extend our average maturity of long-term debt to over nine years with an average interest rate of approximately 6.5%. Maintaining a debt-to-total-capitalization ratio below 50% and reducing debt per mcfe of proved reserves remain key goals of our business strategy.
We completed the following significant financing transactions in 2006:
First Quarter 2006
Second Quarter 2006
Third Quarter 2006
Fourth Quarter 2006
