Purchase Accounting

Periodically, we acquire assets and assume liabilities in transactions accounted for as business combinations, such as the acquisition of the Williston Basin business of Grayson Mill. In connection with the acquisition, we allocated the $5.0 billion of purchase price consideration to the assets acquired and liabilities assumed based on estimated fair values as of the date of the acquisition.

We made a number of assumptions in estimating the fair value of assets acquired and liabilities assumed in the acquisition. The most significant assumptions relate to the estimated fair values of proved and unproved oil and gas properties. Since sufficient market data was not available regarding the fair values of proved and unproved oil and gas properties, we prepared estimates and engaged third-party valuation experts. Significant judgments and assumptions are inherent in these estimates and include, among other things, estimates of reserve quantities, estimates of future commodity prices, drilling plans, expected development costs, lease operating costs, reserve risk adjustment factors and an estimate of an applicable market participant discount rate that reflects the risk of the underlying cash flow estimates.

Estimated fair values ascribed to assets acquired can have a significant impact on future results of operations presented in Devon’s financial statements. A higher fair value ascribed to a property results in higher DD&A expense, which results in lower net earnings. Fair values are based on estimates of future commodity prices, reserve quantities, development costs and operating costs. In the event that future commodity prices or reserve quantities are lower than those used as inputs to determine estimates of acquisition date fair values, the likelihood increases that certain costs may be determined to not be recoverable.
