Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

Operating segments are defined as components of a business that can earn revenues and incur expenses for which discrete financial information is available that is reviewed on a regular basis by the chief operating decision maker (“CODM”). The Company operates as one business and geographic operating and reportable segment.

Chief Operating Decision Maker

The Company’s CODM is its Chief Executive Officer (“CEO”). The CEO oversees the strategic planning and direction of the Company, and the CEO has final approval in assessing the Company’s performance and allocating its resources.

Identification of Reportable Segment

The Company’s single reportable segment derives revenues primarily in North America from customers by designing, engineering, manufacturing, marketing and selling a broad range of advanced, emission-certified engines and power systems that are powered by a wide variety of clean, alternative fuels, including natural gas, propane, and biofuels, as well as gasoline and diesel options, within the power systems, industrial and transportation end markets. Revenue is attributed to geographic areas based on the country of sale. The sources of external revenue by end market and geographic area are previously disclosed in Note 2. Revenue.

The Company evaluated the basis for the CODM's decisions about the allocation of Company resources as well as the basis for the CODM's assessments of the evaluation of the Company's (segment) performance. Specifically, the Company evaluated the financial information that is generally provided and / or is available to the CODM. The Company’s CODM reviews consolidated statements of income to make decisions, allocate resources and assess performance.

Measurement

The CODM assesses performance and decides how to allocate resources primarily using consolidated revenue by end market and consolidated net income (loss). The CODM uses consolidated net income (loss) to monitor budget and forecast information to actual results. The CODM reviews cash, accounts receivable, inventory, accounts payable, and total debt; however other long-lived asset information is not reviewed by the CODM.

The accounting policies of the Company’s single reportable segment are the same as those described in the Note 1. Summary of Significant Accounting Policies and Other Information. The measure of segment assets is consolidated total assets presented in the Company’s Consolidated Balance Sheets. Note 1 Concentrations discloses customers individually accounting for more than 10% of the Company’s consolidated net sales.

Significant Expenses

Significant segment expenses are presented in the Consolidated Statements of Income.
