Note 5 - Long-term Debt

Revolving Credit Facility

The Company’s Second Amendment to the Fifth Amended and Restated Credit Agreement dated December 10, 2014, provides a maximum loan amount of $2.5 billion, current aggregate lender commitments of $1.5 billion, and a maturity date of December 10, 2019. The borrowing base is subject to regular semi-annual redeterminations and was reaffirmed by the Company’s lenders on April 6, 2015, at $2.4 billion. The borrowing base redetermination process under the credit facility considers the value of the Company’s proved oil and gas properties, as determined by the Company’s lenders. The next redetermination date is scheduled for October 1, 2015. Borrowings under the facility are secured by mortgages on assets having a value equal to at least 75 percent of the total value of the Company’s proved oil and gas properties.

The Company must comply with certain financial and non-financial covenants under the terms of its credit facility agreement, including limitations on the payment of dividends to $50.0 million per year. The Company was in compliance with all covenants under the credit facility as of March 31, 2015, and through the filing date of this report.

The following table presents the outstanding balance, total amount of letters of credit, and available borrowing capacity under the Company’s credit facility as of April 29, 2015, March 31, 2015, and December 31, 2014:

The Senior Notes are unsecured senior obligations and rank equal in right of payment with all of the Company’s existing and any future unsecured senior debt, and are senior in right of payment to any future subordinated debt. There are no subsidiary guarantors of the Senior Notes. The Company is subject to certain covenants under the indentures governing the Senior Notes that limit the Company’s ability to incur additional indebtedness, issue preferred stock, and make restricted payments, including dividends; provided, however, that the first $6.5 million of dividends paid each year are not restricted by the restricted payment covenant. The Company was in compliance with all covenants under its Senior Notes as of March 31, 2015, and through the filing date of this report.
