The Company has seven operating segments based on geographic operations that it aggregates into one reportable segment. The Company defines operating segments as components of the organization for which discrete financial information is available and operating results are evaluated on a regular basis by the Chief Operating Decision Maker (“CODM”) in order to assess performance and allocate resources. The Company’s CODM is its Chief Executive Officer. The Company determined it has seven operating segments based on the Company’s seven geographic divisions, which are Central, Midwest, Northeast, Southern, Southeast, Western and Canada. The Company aggregates its operating segments into a single reportable segment based on similarities between the operating segments’ economic characteristics, nature of products sold, production process, type of customer and methods of distribution. The accounting policies of the operating segments are the same as those described in the summary of significant policies. In addition to the Company’s reportable segment, the Company’s consolidated results include both corporate activities and certain other activities. Corporate includes the Company’s corporate office building and support services provided to its subsidiaries. Other includes Tool Source Warehouse, Inc., which functions primarily as an internal distributor of tools.

The CODM assesses the Company’s performance based on the periodic review of net sales, Adjusted EBITDA and certain other measures for each of the operating segments. Adjusted EBITDA is not a recognized financial measure under GAAP. However, we believe it assists investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. Management believes Adjusted EBITDA is helpful in highlighting trends in our operating results, while other measures can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments.

In addition, we utilize Adjusted EBITDA in certain calculations under the ABL Facility and the First Lien Facility. The ABL Facility and the First Lien Facility permit us to make certain additional adjustments in calculating Consolidated EBITDA, such as projected net cost savings, which are not reflected in the Adjusted EBITDA data presented in this Quarterly Report on Form 10-Q.

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations -- Non-GAAP Financial Measures” for a further discussion of this non-GAAP measure.

The following tables present segment results for the three and six months ended October 31, 2019 and 2018:
