Operating segments are defined as components of an enterprise that engage in activities from which it may earn revenues and incur expenses. Separate financial information is available and this information is regularly evaluated by the chief decision maker for the purpose of allocating resources and assessing performance. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Mariner measures financial performance as a single enterprise, allocating capital resources on a project-by-project basis across its entire asset base to maximize profitability. Mariner utilizes a company-wide management team that administers all enterprise operations encompassing the exploration, development and production of natural gas and oil. Since Mariner follows the full cost method of accounting and all of its oil and gas properties and operations are located in the United States, the Company has determined that it has one reporting unit. Inasmuch as Mariner is one enterprise, the Company does not maintain comprehensive financial statement information by area but does track basic operational data by area. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock This element may be used to capture the complete disclosure of reporting segments including data and tables.
