Non-GAAP Financial Measures

This press release includes a presentation of average daily cash margin for our land drilling fleet, and adjusted EBITDA which are not financial measures recognized under generally accepted accounting principles, or GAAP.  Average daily cash margin is a non-GAAP financial measure equal to net income, the most directly comparable GAAP financial measure, minus well service revenue, plus well service expense, income tax expense, other expense, general and administrative expense and depreciation, amortization and impairment, and divided by revenue days for the period.  Adjusted EBITDA is a non-GAAP financial measure equal to net income, the most directly comparable GAAP financial measure, plus interest expense, income tax expense and depreciation, amortization and impairment. We have presented average daily cash margin, average hourly cash margin and adjusted EBITDA because we use these metrics as an integral part of our internal reporting to measure our performance and to evaluate the performance of our senior management. We consider these metrics to be important indicators of the operational strength of our business. A limitation of these metrics, however, is that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our business. Management evaluates the costs of such tangible and intangible assets through other financial measures, such as capital expenditures, investment spending and return on capital. Therefore, we believe that average daily cash margin, and adjusted EBITDA provide useful information to our investors regarding our performance and overall results of operations. Neither average daily cash margin nor adjusted EBITDA is intended to be a performance measure that should be regarded as an alternative to, or more meaningful than, either net income as an indicator of operating performance or to cash flows from operating activities as a measure of liquidity. In addition, none of these metrics is intended to represent funds available for dividends, reinvestment or other discretionary uses, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These non-GAAP financial measures may not be comparable to similarly titled measures presented by other companies, and may not be identical to corresponding measures used in our various agreements.

The following presents a reconciliation of average daily cash margin and adjusted EBITDA to net income, the most directly comparable GAAP financial measure (in thousands, except revenue days and average daily cash margin):
