Our principal products include integrated power control room substations (PCRs®), custom-engineered modules, electrical houses (E-Houses), traditional and arc-resistant distribution switchgear and control gear, medium-voltage circuit breakers, monitoring and control communications systems, motor control centers and bus duct systems. These products are designed for application voltages ranging from </font><font style="font-family:inherit;font-size:10pt;">480</font><font style="font-family:inherit;font-size:10pt;"> volts to </font><font style="font-family:inherit;font-size:10pt;">38,000</font><font style="font-family:inherit;font-size:10pt;"> volts and are used in oil and gas refining, onshore and offshore oil and gas production, petrochemical, liquid natural gas terminals, pipeline, terminal, mining and metals, light rail traction power, electric utility, pulp and paper and other heavy industrial markets. Our product scope includes designs tested to meet both U.S. and international standards, under both the American National Standards Institute (ANSI) and International Electrotechnical Commission. We assist customers by providing value-added services such as spare parts, field service inspection, installation, commissioning, modification and repair, retrofit and retrofill components for existing systems and replacement circuit breakers for switchgear that is obsolete or that is no longer produced by the original manufacturer. We seek to establish long-term relationships with the end users of our systems as well as the design and construction engineering firms contracted by those end users. We believe that our culture of safety and focus on customer satisfaction along with our financial strength allow us to continue to capitalize on opportunities in the industries we serve.</font></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">References to Fiscal </font><font style="font-family:inherit;font-size:10pt;">2019</font><font style="font-family:inherit;font-size:10pt;">, Fiscal </font><font style="font-family:inherit;font-size:10pt;">2018</font><font style="font-family:inherit;font-size:10pt;"> and Fiscal </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;"> used throughout these Notes to Consolidated Financial Statements relate to our fiscal years ended </font><font style="font-family:inherit;font-size:10pt;">September 30, 2019</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">2018</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;">, respectively.</font></div></div>

The most significant estimates used in our financial statements affect revenue recognition and estimated cost recognition on our customer contracts, the allowance for doubtful accounts, provision for excess and obsolete inventory, warranty accruals and income taxes. The amounts recorded for warranties, legal, income taxes, impairment of long-lived assets (when applicable) and other contingent liabilities require judgments regarding the amount of expenses that will ultimately be incurred. We base our estimates on historical experience and on various other assumptions, as well as the specific circumstances surrounding these contingent liabilities, in evaluating the amount of liability that should be recorded. Additionally, the recognition of deferred tax assets requires estimates related to future income and other assumptions regarding timing and future profitability because the ultimate realization of net deferred tax assets is dependent on the generation of future taxable income during periods in which temporary differences become deductible. Estimates routinely change as new events occur, additional information becomes available or operating environments change. Actual results may differ from our prior estimates.</font></div></div>
