Summary Of Significant Accounting Policies [Abstract] |
Summary Of Significant Accounting Policies | B. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of Powell and our wholly-owned subsidiaries. The financial position and results of operation of our Singapore joint venture, in which we held a majority ownership, have also been consolidated. As a result of this consolidation, we record noncontrolling interest on our balance sheet for our joint venture partner’s share of equity in the joint venture. All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain reclassifications have been made in prior years’ financial statements to conform to the presentation used in the current year. These reclassifications have not resulted in any changes to previously reported net income for any periods. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying footnotes. 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, goodwill and other intangible assets, self-insurance, warranty accruals, income taxes and estimates related to acquisition valuations. The amounts recorded for insurance claims, warranties, legal, income taxes 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. Estimates may change as new events occur, additional information becomes available or operating environments change. Actual results may differ from our estimates. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, deposits with banks and highly liquid investments with original maturities of three months or less. Restricted Cash Cash of $1.0 million was held in escrow at September 30, 2011. This restricted cash was related to a purchase of land which closed in October 2011 for $6.5 million. Supplemental Disclosures of Cash Flow Information (in thousands):

Fair Value of Financial Instruments Financial instruments include cash, short-term investments, marketable securities, receivables, payables and debt obligations. Except as described below, due to the short-term nature of the investments, the book value is representative of their fair value. The carrying value of debt approximates fair value as interest rates are indexed to the Federal Funds Rate, the Canadian Prime Rate or the bank’s prime rate. Accounts Receivable Accounts receivable are stated net of allowances for doubtful accounts. We maintain and continually assess the adequacy of the allowance for doubtful accounts representing our estimate for losses resulting from the inability of our customers to pay amounts due to us. This estimated allowance is based on historical experience of uncollected accounts, the level of past due accounts, the overall level of outstanding accounts receivable, information about specific customers with respect to their inability to make payments and expectations of future conditions that could impact the collectibility of accounts receivable. Future changes in our customers’ operating performance and cash flows or in general economic conditions could have an impact on their ability to fully pay these amounts, which could have a material impact on our operating results. In most cases, receivables are not collateralized. However, we utilize letters of credit to secure payment on sales when possible. At September 30, 2012 and 2011, accounts receivable included retention amounts of $8.7 million and $6.1 million, respectively. Retention amounts are in accordance with applicable provisions of engineering and construction contracts and become due upon completion of contractual requirements. Approximately $4.0 million of the retained amount at September 30, 2012, is expected to be collected subsequent to September 30, 2013. Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts Costs and estimated earnings in excess of billings on uncompleted contracts arise when revenues are recorded on a percentage-of-completion basis but cannot be invoiced under the terms of the contract. Such amounts are invoiced upon completion of contractual milestones. Costs and estimated earnings in excess of billings on uncompleted contracts also include certain costs associated with unapproved change orders. These costs are included when change order approval is probable. Amounts are carried at the lower of cost or net realizable value. Revenue is recognized to the extent of costs incurred when recovery is probable. The amounts recorded involve the use of judgments and estimates; thus, actual recoverable amounts could differ from original assumptions. In accordance with industry practice, assets and liabilities related to costs and estimated earnings in excess of billings on uncompleted contracts, as well as billings in excess of costs and estimated earnings on uncompleted contracts, have been classified as current. The contract cycle for certain long-term contracts may extend beyond one year; thus, collection of amounts related to these contracts may extend beyond one year. Inventories Inventories are stated at the lower of cost or market using weighted-average methods and include the cost of materials, labor and manufacturing overhead. We use estimates in determining the level of reserves required to state inventory at the lower of cost or market. Our estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. Property, Plant and Equipment Property, plant and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets. Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and improvements, which extend the useful lives of existing equipment, are capitalized and depreciated. Upon retirement or disposition of property, plant and equipment, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in the Consolidated Statements of Operations. We review property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying value may not be realizable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if an impairment of such asset is necessary. This requires us to make long-term forecasts of the future revenues and the costs related to the assets subject to review. Forecasts require assumptions about demand for our products and future market conditions. Estimating future cash flows requires significant judgment, and our projections may vary from cash flows eventually realized. Future events and unanticipated changes to assumptions could require a provision for impairment in a future period. The effect of any impairment would be reflected in income (loss) from operations in the Consolidated Statements of Operations. In addition, we estimate the useful lives of our property, plant and equipment and periodically review these estimates to determine whether these lives are appropriate. Intangible Assets Which Are Amortized The costs of intangible assets with determinable useful lives are amortized over their estimated useful lives. When certain events or changes in operating conditions occur, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if an impairment of such assets is necessary. For intangible assets that are amortized, we review their estimated useful lives and evaluate whether events and circumstances warrant a revision to the remaining useful life. For additional information regarding our intangible assets and related impairment, see Note D. Goodwill and Indefinite Lived Assets Goodwill and other intangible assets with indefinite useful lives are evaluated for impairment annually, or immediately if conditions indicate that impairment could exist. The evaluation requires a two-step impairment test to identify potential goodwill impairment and measure the amount of a goodwill impairment loss. The first step of the test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss. Both steps of the goodwill impairment testing involve significant estimates. Income Taxes We account for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing our provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. We believe that the deferred tax asset recorded as of September 30, 2012, is realizable through future reversals of existing taxable temporary differences and future taxable income. If we were to subsequently determine that we would be able to realize deferred tax assets in the future in excess of our net recorded amount, an adjustment to deferred tax assets would increase earnings for the period in which such determination was made. We will continue to assess the adequacy of the valuation allowance on a quarterly basis. Our judgments and tax strategies are subject to audit by various taxing authorities. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Accounting literature also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial statements. Revenue Recognition Our revenues are primarily generated from engineering and manufacturing of custom products under long-term contracts that may last from one month to several years, depending on the contract. Revenues from long-term contracts are recognized on the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting, revenues are recognized as work is performed primarily based on the estimated completion to date calculated by multiplying the total contract price by percentage of performance to date, based on total costs or total labor dollars incurred to date 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 determined to be a more accurate method of measuring the progress of the projects. 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, 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 in 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. 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. Warranties We provide for estimated warranty costs at the time of sale based upon historical rates applicable to individual product lines. In addition, specific provisions are made when the costs of such warranties are expected to exceed accruals. Our standard terms and conditions of sale include a warranty for parts and service for the earlier of 18 months from the date of shipment or 12 months from the date of initial operations. Occasionally projects require warranty terms that are longer than our standard terms due to the nature of the project. Extended warranty terms may be negotiated and included in our contracts. Research and Development Expense Research and development costs are charged to expense as incurred. These costs are included as a component of selling, general and administrative expenses on the Consolidated Statements of Operations. Such amounts were $7.7 million, $7.5 million and $6.5 million in fiscal years 2012, 2011 and 2010, respectively. Foreign Currency Translation The functional currency for our foreign subsidiaries is the local currency in which the entity is located. The financial statements of all subsidiaries with a functional currency other than the U.S. Dollar have been translated into U.S. Dollars. All assets and liabilities of foreign operations are translated into U.S. Dollars using year-end exchange rates, and all revenues and expenses are translated at average rates during the respective period. The U.S. Dollar results that arise from such translation, as well as exchange gains and losses on intercompany balances of a long-term investment nature, are included in the cumulative currency translation adjustments in accumulated other comprehensive income in stockholders’ equity. Stock-Based Compensation We measure stock-based compensation cost at the grant date based on the fair value of the restricted stock award and recognize it as expense over the applicable vesting period of the stock award using the straight-line method. Excess income tax benefits related to share-based compensation expense that must be recognized directly in equity are considered financing rather than operating cash flow activities. Derivative Financial Instruments As part of managing our exposure to changes in foreign currency exchange rates, we periodically utilize foreign exchange forward contracts. The objective of these contracts is to minimize impacts to cash flows and profitability due to changes in foreign currency exchange rates on accounts receivable, accounts payable and forecasted cash transactions. These contracts are recorded in the Consolidated Balance Sheets at fair value, which is based upon an income approach consisting of a discounted cash flow model that takes into account the present value of the future cash flows under the terms of the contracts using current market information as of the reporting date, such as foreign currency spot and forward rates. We formally document our hedging relationships, including identifying the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking the hedge transaction. We also formally assess, both at inception and at least quarterly thereafter, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the cash flows of the hedged item. The effective portion of the change in fair value of a derivative is recorded as a component of accumulated other comprehensive income in the Consolidated Balance Sheets. When the hedged item affects the income statement, the gain or loss included in accumulated other comprehensive income is reported on the same line in the Consolidated Statements of Operations as the hedged item. In addition, any ineffective portion of the changes in the fair value of derivatives used as cash flow hedges is reported in the Consolidated Statements of Operations as the changes occur. If it is determined that a derivative ceases to be a highly effective hedge, or it is probable that the forecasted transaction will not occur, we discontinue hedge accounting and any unrealized gains or losses are recorded in the consolidated financial statements. We provide 1) qualitative disclosures regarding the objectives and strategies for using derivative instruments and engaging in hedging activities in the context of our overall risk exposure; 2) quantitative disclosure in tabular format of the fair values of derivative instruments and their gains and losses and 3) disclosures about credit-risk related contingent features in derivative instruments. Accumulated Other Comprehensive Income (Loss) Accumulated other comprehensive income (loss), which is included as a component of stockholders’ equity net of tax, includes unrealized gains or losses on derivative instruments, postretirement benefit adjustments and currency translation adjustments in foreign consolidated subsidiaries. New Accounting Standards From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the FASB), which are adopted by us as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on our consolidated statements upon adoption. In January 2010, the FASB issued updated guidance to amend the disclosure requirements related to recurring and nonrecurring fair value measurements. This update requires new disclosures about significant transfers of assets and liabilities between Level 1 and Level 2 of the fair value hierarchy (including the reasons for these transfers) and the reasons for any transfers in or out of Level 3. This update also requires a reconciliation of recurring Level 3 measurements about purchases, sales, issuances and settlements on a gross basis. In addition to these new disclosure requirements, this update clarifies certain existing disclosure requirements. For example, this update clarifies that reporting entities are required to provide fair value measurement disclosures for each class of assets and liabilities, rather than each major category of assets or liabilities. This update also clarifies the requirement for entities to disclose information about both the valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements. This update became effective for us with the interim and annual reporting period beginning after December 15, 2009, our fiscal year 2011, except for the requirement to provide the Level 3 activity of purchases, sales, issuances and settlements on a gross basis, which b ec a me effective for us with the interim and annual reporting period beginning after December 15, 2010, our fiscal year 2012. We were not required to provide the amended disclosures for any previous periods presented for comparative purposes. Other than requiring additional disclosures, adoption of this update has not had a material impact on our consolidated financial statements. In May 2011, the FASB issued accounting guidance related to fair value measurement, which amends current guidance to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards. This guidance generally represents clarification of fair value measurement standards, but also includes instances where a particular principle or requirement for measuring fair value of disclosing information about fair value measurements has changed. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We will adopt this guidance for our fiscal year beginning October 1, 2012. We do not expect this pronouncement to have a material effect on our consolidated financial statements. In June 2011, the FASB issued new accounting guidance on the presentation of comprehensive income in financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or in two separate, but consecutive, statements. Under the single-statement approach, entities must include the components of net income, a total for net income, the components of other comprehensive income and a total for comprehensive income. Under the two-statement approach, entities must report an income statement and, immediately following, a statement of other comprehensive income. Under either method, entities must display adjustments for items reclassified from other comprehensive income to net income in both net income and other comprehensive income. The provisions for this guidance are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We will adopt this guidance for our fiscal year beginning October 1, 2012. In September 2011, the FASB issued new accounting guidance which simplifies how an entity is required to test goodwill for impairment. Under this guidance, an entity would be allowed to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. This new guidance includes a number of factors to consider in conducting the qualitative assessment. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, our Fiscal 2013. Early adoption is permitted; however, we will not adopt this guidance until October 1, 2012. This guidance is not expected to have a material impact on our reported results of operations or financial position. In July 2012, the FASB issued an accounting standards update regarding the testing of indefinite-lived intangible assets for impairment. Under this update, an entity has the option to first assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the events and circumstances, an entity concludes that it is more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if any entity concludes otherwise, it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment testing by comparing the fair value with the carrying amount. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative test. An entity will be able to resume performing the qualitative assessment in any subsequent period. This update is effective for annual and interim tests performed for fiscal years beginning after September 15, 2012, our fiscal year 2013. Early adoption is permitted; however, we will not adopt this guidance until October 1, 2012. This guidance is not expected to have a material impact on our reported results of operations or financial position. In August 2012, the SEC adopted a rule mandated by the Dodd-Frank Act to require companies to publicly disclose their use of conflict minerals that originated in the Democratic Republic of the Congo or an adjoining country. The final rule applies to a company that uses minerals including tantalum, tin, gold or tungsten. The final rule requires companies to provide disclosure on a new form filed with the SEC, with the first specialized disclosure report due on May 31, 2014, for the 2013 calendar year, and annually on May 31 each year thereafter. We are currently evaluating the impact of adoption. Subsequent Events We evaluated subsequent events through the time of filing this Annual Report on Form 10-K. No significant events occurred subsequent to the balance sheet or prior to the filing of this report that would have a material impact on our consolidated financial statements or results of operations.
