Thank you, Chris. I'd like to start by summarizing our financial results for the quarter followed by an update on our liquidity and recent credit facility amendment and conclude with our hedge position.
Again, adjusted EBITDA for the first quarter was $81 million, which exceeded our internal targets. As previously discussed, production was largely in line with operating cost of $35.7 million and significantly beat our targets.
Covering a few other line items. Gathering, processing and transportation costs of $0.42 per Mcfe or $9.2 million were also in line with expectations. G&A in the first quarter of 2016 was $13.5 million and included noncash charges of $2.6 million for unit-based compensation expenses and onetime charges associated with the reduction in force.
So that's a cash run rate of $10.9 million per quarter, in line with our annual guidance expectations. Given the staff reductions and some other efficiencies realized, we expect to see that run rate total dollar figure trend down over the course of the year.
Now moving on to discussion of debt and liquidity. On April 14, we announced our semiannual borrowing base redetermination, which resulted in a revised borrowing base of $925 million, a decrease of 21% from the previous level and in line with our expectations.
In addition to the revised borrowing base, the partnership and the commercial lending group agreed to amend certain terms of MEMP's credit facility. The new terms included a maximum first lien secured leverage covenant of 3.25x and, as John mentioned earlier, additional restrictions were placed on future cash distributions based on total leverage, liquidity and other financial tests.
We'd again like to thank our 28-member bank group as we recognize this is a difficult environment for all parties. All in, we view the spring redetermination as a successful outcome, given that we still have ample liquidity, along with the flexibility needed to execute our business plan for the year.
As of April 29, we had total debt outstanding of $2 billion. This includes $1.2 billion of senior unsecured notes and $789 million of revolver debt, leaving revolver availability of $134 million, including the impact of $2 million in letters of credit.
Given the liquidity enhancing measures we have implemented in our significant positive free cash flow, we do not expect this level of liquidity to impede our strategy going forward. I'd also like to point out we remain in compliance with the financial covenants under our revolving credit facility, which include the first lien coverage test of 3.25x and interest coverage test of over 2.5x and a current ratio test of 1x. Importantly, our 2 tranches of senior notes do not mature until 2021 and 2022.
Next, I would like to talk about have our hedging strategy and execution. As you've heard from us many times, we have a tremendous asset in our hedge portfolio, which had a recent mark-to-market value of approximately $605 million and continues to play an integral role in MEMP's cash flow certainty in this environment. On a percentage of total production hedged basis, we are approximately 70% to 90% hedged through 2018 and 53% hedged in 2019.
For those same time periods, we're hedged on crude oil at prices of approximately $85 per barrel and natural gas prices above $4. Our hedges uniquely position us in this downturn and help provide price stability for years to come. Additional detail related to our hedge program is posted on our website under the Investor Relations section.
In terms of tracking progress to date against our full year 2016 guidance announced in January, we continue to believe these estimates are very achievable. And as a reminder, we will see declining production throughout the year, given our development program slows down significantly with only 2 additional completion scheduled this year and no further plans to drill new wells.
We expect to exit the year at the low end of our annual guidance range of 228 million to 243 million cubic feet equivalent per day and as our production declines, per unit metrics will be a little distorted on a comparative basis. As a result, it will be important to also look at our metrics on a total dollar basis.
Wrapping up, with a strong asset base, a best-in-class hedge portfolio, our continued gains in operational efficiencies and a strong cash flow forecast we've laid out today, we are optimistic that we are positioning ourselves for success through this downturn.
This concludes our formal remarks regarding MEMP's first quarter 2016 earnings call. Thank you for your time. And operator, we'd now like to open up the line for any questions.
