(we, us, our, Powell or the Company) was incorporated in the state of Delaware in 2004 as a successor to a Nevada company incorporated in 1968. The Nevada company was the successor to a company founded by William E. Powell in 1947, which merged into the Company in 1977. Our major subsidiaries, all of which are wholly owned, include: Powell Electrical Systems, Inc.; Powell (UK) Limited; Powell Canada Inc. and Powell Industries International, B.V.</font></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We develop, design, manufacture and service custom-engineered equipment and systems for the distribution, control and monitoring of electrical energy designed to (1) distribute, control and monitor the flow of electrical energy and (2) provide protection to motors, transformers and other electrically powered equipment. 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, offshore oil and gas production, petrochemical, 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 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and repair, retrofit and retrofill components for existing systems and replacement circuit breakers for switchgear that is obsolete or that is no longer produced by the original manufacturer.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.</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;">2018</font><font style="font-family:inherit;font-size:10pt;">, Fiscal </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;"> and Fiscal </font><font style="font-family:inherit;font-size:10pt;">2016</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, 2018</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2016</font><font style="font-family:inherit;font-size:10pt;">, respectively.</font></div></div>

Revenues from long-term contracts are recognized on the percentage-of-completion method of accounting. Occasionally a contract may require that we segment the project into specific deliverables for revenue recognition. Segmenting a contract may result in different interim rates of profitability for each scope of service than if we had recognized revenue on a combined basis.</font></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Under the percentage-of-completion method of accounting, revenues are recognized as work is performed. The revenue earned to date is calculated by multiplying the total contract price by the percentage of performance to date, which is based on total costs or total labor dollars incurred to date compared to the total estimated costs or total labor dollars estimated at completion. The method used to determine the percentage of completion is typically the cost method, unless the labor method is a more accurate method of measuring the progress of the project. Application of the percentage-of-completion method of accounting requires the use of estimates of costs to be incurred for the performance of the contract. Contract costs include all direct material costs, direct labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and all costs associated with operation of equipment. The cost estimation process is based upon the professional knowledge and experience of our engineers, project managers and financial professionals. Factors that are considered in estimating the work to be completed and ultimate contract recovery include the availability and productivity of labor, the nature and complexity of the work to be performed, the effect of change orders, the availability of materials, the effect of any delays on our project performance and the recoverability of any claims. Changes in job performance, job conditions, estimated profitability and final contract settlements, including our estimate of liquidated damages, if any, may result in revisions to costs and income, with their effects being recognized in the period in which the revisions are determined. Whenever revisions of estimated contract costs and contract values indicate that the contract costs will exceed estimated revenues, thus creating a loss, a provision for the total estimated loss is recorded in that period.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Revenues associated with maintenance, repair and service contracts are recognized when the services are performed. Expenses related to these types of services are recognized as incurred.</font></div></div>

The most significant estimates used in our financial statements affect revenue and cost recognition for construction 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. Estimates may change as new events occur, additional information becomes available or operating environments change. Actual results may differ from our estimates.</font></div></div>
