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. 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. 

Under the percentage-of-completion method of accounting, revenues are recognized as work is performed. The estimated completion 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. 

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. We use past experience and historical claims to determine the estimated liability. Actual results could differ from our estimate. 

## Research and Development Expense 

Research and development costs are charged to expense as incurred. Such amounts were $8.5 million, $7.7 million and $7.5 million in Fiscal 2013, 2012 and 2011, 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 award. Compensation expense is recognized over the period during which the employee is required to provide service in exchange for the awards, typically the vesting period. 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. 

## 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 August 2012, the Securities and Exchange Commission (SEC) adopted a rule mandated by the Wall Street Reform and Consumer Protection Act to require companies to publicly disclose their use
