million as compared to $380.6 million for the full year 2014, reflecting lower prices for all commodities partially offset by increased production volumes.  Total revenues including current period settlements of matured derivative contracts were $347.2 million for the full year 2015 as compared to $385.1 million for the full year 2014.

For the quarter ended December 31, 2015, the Company reported adjusted net income of $0.6 million as compared to adjusted net income of $15.7 million for the three months ended December 31, 2014.  Adjusted net income for the full year 2015 was $2.2 million as compared to $68.8 million for the full year 2014, with significantly lower commodity prices offsetting higher production volumes.

Operational Results

Cleveland

For the full year 2015, the Company spud 51 wells, completed 70 wells and brought on first production from 77 wells, all in the Cleveland.  The Company has not spud any wells thus far in 2016.

Daily net production in the Cleveland was 17.7 MBoe/d in the fourth quarter of 2015 as compared to 17.2 MBoe/d in the fourth quarter of 2014.  Full year 2015 production in the Cleveland was 18.4 MBoe/d for 2015, an 8% increase from 2014 full year production of 17.0 MBoe/d.

Capital Expenditures

During the fourth quarter of 2015, the Company spent $14.1 million on capital expenditures, of which $8.0 million was related to drilling and completing operated wells, representing 57% of the total capital expenditures in the quarter.  The remaining $6.1 million was primarily related to field maintenance and leasing.

For the full year 2015, the Company spent $200.1 million on capital expenditures, of which $173.2 million was related to drilling and completing operated wells, representing 87% of the total capital expenditures in the year.  This compares to revised 2015 capital expenditure guidance of $210 million.

2016 Capital Budget and Operating Plan

The Company has established an initial capital budget of $25 million for 2016, with the majority dedicated to capital workovers and field optimization activities.  The Company will continue to monitor market conditions and may determine at a later date to spend additional capital which may include redeploying rigs to resume drilling activities or leasing.  At present, the Company continues to negotiate with vendors regarding service costs and does not plan on resuming its drilling program until well costs create acceptable rates of return at strip prices.

Liquidity and Hedging

As of December 31, 2015, the Company had $400 million undrawn on its revolving credit facility (with $110 million in outstanding borrowings) and approximately $22 million in cash.

In January and February 2016, through several open market and privately negotiated purchases, the Company purchased an aggregate principal amount of $170.5 million of its senior unsecured notes.  As of February 29, 2016, the Company had purchased $70.5 million principal amount of its 6.75% senior unsecured notes due 2022 for $27.1 million, and $100 million principal amount of its 9.25% senior unsecured notes due 2023 for $46.5 million, in each case excluding accrued interest and including any associated fees.  The Company used cash on hand and borrowings from its revolver to fund the note purchases.  As a result of these purchases, as of February 29, 2016, the Company had aggregate principal amount of senior unsecured notes outstanding of $579.5 million,

outstanding borrowings under its revolving credit facility of $185 million, $325 million undrawn on its revolving credit facility, and $46 million in cash.

As a result of the Company’s reduced drilling activity and its expectation of recognizing a gain associated with the debt repurchases, the Company is likely to generate taxable income in 2016.

The estimated mark-to-market value of the Company’s commodity price hedges in 2016 and beyond was $261 million incorporating strip pricing as of February 29, 2016.  In recent months, the Company has entered into offsetting transactions in order to lock in gains associated with hedge volumes above projected production.  The following table summarizes the Company’s commodity derivative contracts outstanding:

Non-GAAP Financial Measures and Reconciliations

EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies.

We define EBITDAX as earnings before interest expense, income taxes, depreciation, depletion and amortization, exploration expense, gains and losses from derivatives less the current period settlements of matured derivative contracts, and the other items described below.  EBITDAX is not a measure of net income as determined by United States generally accepted accounting principles, or GAAP.  Management believes EBITDAX is useful because it allows them to more effectively evaluate our operating performance and compare the results of our operations from period to period and against our peers without regard to our financing methods or capital structure.  We exclude the items listed above from net income in arriving at EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired.  EBITDAX has limitations as an analytical tool and should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our liquidity. Certain items excluded from EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historical costs of depreciable assets.  Our presentation of EBITDAX should not be construed as an inference that our results will be unaffected by unusual or non-recurring items and should not be viewed as a substitute for GAAP.  Our computations of EBITDAX may not be comparable to other similarly titled measures of other companies.

The following table sets forth a reconciliation of net income (loss) as determined in accordance with GAAP to EBITDAX for the periods indicated:

Non-GAAP Financial Measures and Reconciliations

Adjusted Net Income is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements.  We define Adjusted Net Income as net income excluding the impact of certain non-cash items including gains or losses on commodity derivative instruments not yet settled, impairment of oil and gas properties, non-cash compensation expense, and the other items described below.  We believe adjusted net income and adjusted earnings per share are useful to investors because they provide readers with a more meaningful measure of our profitability before recording certain items for which the timing or amount cannot be reasonably determined.  However, these measures are provided in addition to, not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP.  The following table provides a reconciliation of net income (loss) as determined in accordance with GAAP to adjusted net income for the periods indicated:

(1) In arriving at adjusted net income, the tax impact of the adjustments to net income is determined by applying the appropriate tax rate to each adjustment and then allocating the tax impact between the controlling and non-controlling interests.

Non-GAAP Financial Measures and Reconciliations

Adjusted Earnings per Share is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements.  We define Adjusted Earnings per Share as earnings per share plus that portion of the components of adjusted net income allocated to the controlling interests divided by weighted average shares outstanding.  We believe adjusted earnings per share is useful to investors because it provides readers with a more meaningful measure of our profitability before recording certain items for which the timing or amount cannot be reasonably determined.  However, these measures are provided in addition to, not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP.  The following table provides a reconciliation of earnings per share to adjusted earnings per share for the period indicated:

(1) In arriving at adjusted net income, the tax impact of the adjustments to net income is determined by applying the appropriate tax rate to each adjustment and then allocating the tax impact between the controlling and non-controlling interests.
