Thank you, Chris. I'd like to start by summarizing some additional financial results for the quarter, followed by an update on our liquidity, hedge positions and updated guidance. Net cash provided by operating activities was $79 million for the second quarter, a $2 million increase from the first quarter. Adjusted EBITDA for the second quarter was $84.1 million, which was a significant leap versus our previously announced annual guidance expectations, and an increase of $2.8 million from the first quarter.
The increase in net operating cash flow and adjusted EBITDA was largely a result of the previously discussed operating cost improvements. G&A in the second quarter was $15.2 million, but included noncash charges for bad debt expense of $1.6 million, transaction-related costs of $900,000 and noncash charges of $2.5 million per unit-based compensation expenses. So that's a recurring cash run rate of $10.2 million per quarter, in line with our annual guidance expectations. As Bill previously stated, 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. Since year-end 2015, we have made great strides lowering total debt by $197 million. This has come through free cash flow generation, open-market repurchases and asset divestitures. Lowering total debt remains a key focus and strategy for the partnership going forward. As we are able, we will continue to execute on market repurchases of our high-yield notes, whether it be through our ATM equity program or as the credit facility allows. And as was the case with the recent divestitures, we will continue to evaluate further asset sales that are credit and liquidity enhancing.
In regard to MEMP's revolver debt, outstanding has fallen by $113 million since year-end. As of July 29, our revolver balance currently sits at $723 million with an availability of $200 million after including the impact of $2.1 million in letters of credit. Given the ongoing success for our cost-control measures and our ability to continue to generate positive free cash flow in future periods, we believe that level of liquidity supports our strategy going forward. Our next regularly scheduled borrowing base for determination will occur later this fall.
Last from the revolver, our credit facility matures in March 2018. We will be discussing extending this maturity with our credit banks later this year and likely into the first quarter of 2017.
I will also add that we are in compliance with all of our financial covenants and do not forecast as being an issue in the near-term assuming strip pricing around current levels.
We've also been actively reducing our senior unsecured notes and currently have $1.1 billion outstanding. We're able to retire approximately $84 million in the second quarter with an aggregate consideration of $41.5 million, implying a repurchase price of approximately 48% of par value.
The senior note repurchases were partially funded by $1.7 million in sales of common units under MEMP's aftermarket program with a balance of $39.8 million funded through the monetization of 2016 oil and NGL hedges.
Last on the senior unsecured notes, it's important to remember that we do not have any maturities until 2021 and 2022.
Next, I'd like to discuss the potential for cancellation of debt income, or CODI, for MEMP's debt repurchases. Please note that we are not tax advisers and you should consult your own tax professionals regarding your tax situation. CODI is generally the difference between price we pay to repurchase debt and the price at which the debt was issued. Since we are a partnership and each of our unitholders are limited partners, this income will be included on our 2016 Schedule K-1s. The senior note repurchases completed year-to-date will generate approximately $41.7 million of CODI or $0.50 per unit. This CODI will be allocated to unitholders of record during the months in which the repurchases close. Please note that this is $0.50 per unit of taxable income, not $0.50 per unit of tax liability. We anticipate the MEMPs unit [ph] holders, depending on when they purchased our units, will have offsets to this taxable income driven by ordinary losses from operations generated this year, along with taxable losses from our divestitures completed during the second quarter. These divestitures, because of the value at which they will carry on our balance sheet, may create substantial tax yield at year-end. That said, I would like to note that each individual unitholder does have a unique cost basis among the assets and depletion amount for the calculation of this specific ordinary income or loss each year.
Next, I would like to talk about our hedging strategy and execution. As you heard from us many times, we have a tremendous asset in our hedge portfolio, which continues to play an integral role in MEMP's strategy in this environment and had a recent mark-to-market value of approximately $524 million. On a percentage of total production hedged basis, we remain approximately 70% to 95% hedged through 2018 and almost 60% hedged in 2019. During the 2017 to 2019 time period, we are hedged on accrual prices of approximately $85 per barrel and natural gas prices above $4.
As I previously mentioned, MEMP recently liquidated certain crude oil and NGL hedges primarily related to the assets we divested for the period of July to December 2016 and utilized these proceeds to buy back senior notes. So it's important to note these near-term hedges do not carry any value on our borrowing base due to the bank's rolling off the first 6 months of production and evaluation. Subsequent to these transactions, MEMP partially re-hedged the oil volumes with swaps and puts for the same period. The swap contracts were executed at strip pricing and cover approximately 2,000 barrels a day. The put contracts are at forward price of $40 and also cover approximately 2,000 barrels a day. In addition, basis hedges related to the divested properties in 2016 to 2017 have been terminated and settled. Additional detail related to our hedge program is posted on our website under the Investor Relations section.
Due to our strong results in the first half of 2016 and the recent asset divestitures, we have updated our full year 2016 guidance. While production is lower due to the asset divestitures and development activity, our full year cash flow remains strong. MEMP's forecasted distributable cash flow less our anticipated distributions we have met with $127 million to $137 million of free cash flow available to reduce leverage. This is significantly higher than our initial guidance expectations and is driven by the substantial progress we've made in reducing MEMP's cost structure. Note that today's updated full year guidance includes actual results for the first half of the year and our internal forecasts for performance in the second half of the year.
Wrapping up, with strong and more focused asset base, a strong hedge portfolio, our continued gains in operational efficiencies and the cash flow forecast we have weighed out today, we are optimistic but we are positioning ourselves for success through this downturn. As John mentioned, we will continue to review all options of lower leverage and enhanced liquidity.
This concludes our formal remarks regarding MEMP's Second Quarter 2016 Earnings Call. Thank you for your time. And operator, we'd now like to open up the line for any questions.
