(11) Reportable Segment

The Company has identified one reportable segment based on the distinctness of the Company’s activities and products: lime and limestone operations. All operations are in the United States. In evaluating the operating results of the Company, management primarily reviews revenues, gross profit and operating profit from the lime and limestone operations. Operating profit from its lime and limestone operations includes all of the Company’s selling, general and administrative costs. The Company does not allocate interest income and expense and other expense to its lime and limestone operations.

During 2019, the Company’s natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and the Company does not expect the results from its natural gas interests to be of significance in future periods. The revenues, gross profit and operating profit from the Company’s natural gas interests are included in Other for the Company’s reportable segment disclosures. Other identifiable assets include assets related to its natural gas interests, unallocated corporate assets and cash items. Segment disclosures for 2018 and 2017 have been recast to be consistent with the 2019 presentation.
