The CODM reviews internal management reports on a monthly basis that are consistent with the information  provided in the statement of profit or loss and other comprehensive income, statement of financial position and  statement of cash flows. As a result no reconciliation is required, because the information as presented is used by  the CODM to make strategic decisions.  The Company’s strategic focus is the exploration, development and production of large, repeatable onshore resource  plays in North America, which is the Company’s only major line of business and only major geographic area of  operations. All of the basins and/or formations in which the Company operates have common operational  characteristics, challenges and economic characteristics. As such, Management has determined, based upon the  reports reviewed and used to make strategic decisions by the Chief Operating Decision Maker (“CODM”), whom is  the Company’s Managing Director and Chief Executive Officer, that the Company has one reportable segment being  oil and natural gas exploration and production in North America.
