The change in revenues for the 2011 quarter and year reflects increased prices realized from oil sales and an increase in production volumes (up 9.5% year over year) partially offset by lower natural gas prices. Revenue benefitted from a favorable pricing trend during the year and the realization of premiums to WTI pricing attributable to LLS and HLS pricing for our oil production. The increase in production reflects accelerated investments in our development and infrastructure upgrade program during the second half of the year. The improvement in net income, discretionary cash flow and EBITDAX was driven by revenue gains and was partially offset by the incurrence of $3.9 million of dry hole costs in 2011. 2011 full year net income also benefitted from a one-time gain of $7.7 million on the retirement of our prior credit facilities and a $4.8 million reduction in net interest expense.Operational Highlights Operational highlights for 2011 included:
