Note 2. Acquisition of Cedar Creek Anticline Properties in 2013

On March 27, 2013, we acquired producing assets in the Cedar Creek Anticline ("CCA") of Montana and North Dakota from a wholly-owned subsidiary of ConocoPhillips Company for $1.0 billion after final closing adjustments. This acquisition was not reflected as an Investing Activity on our Unaudited Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2013 due to the movement of the cash used to acquire these assets through a qualified intermediary to facilitate a like-kind-exchange treatment under federal income tax rules. This acquisition meets the definition of a business under the FASC Business Combinations topic. The fair values assigned to assets acquired and liabilities assumed in this acquisition have been finalized and no adjustments have been made to fair value amounts previously disclosed in our Form 10-K for the period ended December 31, 2013.

For the three months ended September 30, 2013 and for the period from March 27, 2013 to September 30, 2013, we recognized $97.1 million and $189.8 million of oil, natural gas, and related product sales, respectively, from the property interests acquired in the CCA acquisition. For the three months ended September 30, 2013 and for the period from March 27, 2013 to September 30, 2013, we recognized $70.9 million and $138.8 million of net field operating income (defined as oil, natural gas and related product sales less lease operating expenses, production and ad valorem taxes, and marketing expenses), respectively, related to the CCA acquisition.
