Actual results could differ from those estimates, and changes in these estimates are recorded when known. Significant estimates with regard to these financial statements include the fair value determination of acquired assets and liabilities, the assessment of asset retirement obligations, the estimate of proved oil and natural gas reserves and related present value estimates of future net cash flows, and the estimates of fair value for long-lived assets.</span></div>
