9.  DEBT

In January 2014, we executed a loan agreement with the International Finance Corporation (“IFC”) for a $65.0 million revolving credit facility (“IFC credit facility”), which is secured by the assets of our Gabon subsidiary, VAALCO Gabon (Etame), Inc. In May 2015, the IFC credit facility was amended to remove the affirmative covenant that we maintain a debt to equity ratio at or below that of 60:40, which lifted a restriction on borrowing capacity. Under the amended IFC credit facility agreement, we are required to maintain a ratio of our net debt to EBITDAX (as defined in the credit agreement) of not more than 3.0 to1.0. The borrowing base under the IFC credit facility is based upon our proved reserves and risk adjusted probable reserves and is re-determined semi-annually by the IFC. In addition, the borrowing base may be adjusted pursuant to certain non-scheduled re-determinations. As a result of the borrowing base redetermination as of June 30, 2015, our borrowing capacity was reaffirmed at the maximum capacity under the facility. 

Forecasting our compliance with the financial covenant in future periods is inherently uncertain. Factors that could impact our debt to EBITDAX in future periods include future realized prices for sales of oil and natural gas, estimated future production, returns generated by our capital program, and future interest costs, among others. We are in compliance with all financial covenants as of June 30, 2015.

Borrowings outstanding under the IFC credit facility were $15.0 million as of June 30, 2015, and are due in full upon maturity in December 2019. The borrowings approximate fair value as the interest approximates current market rates for similar instruments. The interest rate on outstanding borrowings averaged 4.94% in the six months ended June 30, 2015, including commitment fees on the available balance, with related incurred interest expense of $0.4 million and $0.7 million for the three and six months ended June 30, 2015.  

We capitalize interest and commitment fees related to expenditures made in connection with exploration and development projects that are not subject to current depletion. Interest and commitment fees are capitalized only for the period that activities are in progress to bring these projects to their intended use. For the three and six months ended June 30, 2015,  $0.3 million and $0.5 million of interest expense was capitalized, as was $0.3 million and $0.5 million for the three and six months ended June 30, 2014.
