Summary Of Significant Accounting Policies (Policy) | 12 Months Ended
--- | ---
Sep. 29, 2012
Accounting Policies [Abstract] |
Consolidation | Consolidation: The consolidated financial statements include the accounts of Moog Inc. and all of our U.S. and foreign subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year | Fiscal Year: Our fiscal year ends on the Saturday that is closest to September 30. The consolidated financial statements include 52 weeks for the years ended September 29, 2012, October 1, 2011 and October 2, 2010.
Operating Cycle | Operating Cycle: Consistent with industry practice, aerospace and defense related inventories, unbilled recoverable costs and profits on long-term contract receivables, customer advances and contract loss reserves include amounts relating to contracts having long production and procurement cycles, portions of which are not expected to be realized or settled within one year.
Foreign Currency Translation | Foreign Currency Translation: Assets and liabilities of subsidiaries that prepare financial statements in currencies other than the U.S. dollar are translated using rates of exchange as of the balance sheet date and the statements of earnings are translated at the average rates of exchange for each reporting period.
Use Of Estimates | Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and assumptions.
Revenue Recognition | Revenue Recognition: We recognize revenue using either the percentage of completion method for contracts or as units are delivered or services are performed.
Percentage of Completion Method for Contracts | Percentage of completion method for contracts: Revenue representing 32% of 2012 sales was accounted for using the percentage of completion, cost-to-cost method of accounting. This method of revenue recognition is predominantly used within the Aircraft Controls and Space and Defense Controls segments due to the contractual nature of the business activities, with the exception of their respective aftermarket activities. The contractual arrangements are either firm fixed-price or cost-plus contracts and are primarily with the U.S. Government or its prime subcontractors, foreign governments or commercial aircraft manufacturers, including Boeing and Airbus. The nature of the contractual arrangements includes customers’ requirements for delivery of hardware as well as funded nonrecurring development work in anticipation of follow-on production orders. Revenue on contracts using the percentage of completion, cost-to-cost method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total estimated contract revenue, less cumulative revenue recognized in prior periods. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for substantially all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations. Occasionally, it is appropriate to combine or segment contracts. Contracts are combined in those limited circumstances when they are negotiated as a package in the same economic environment with an overall profit margin objective and constitute, in essence, an agreement to do a single project. In such cases, revenue and costs are recognized over the performance period of the combined contracts as if they were one. Contracts are segmented in limited circumstances if the customer had the right to accept separate elements of the contract and the total amount of the proposals on the separate components approximated the amount of the proposal on the entire project. For segmented contracts, revenue and costs are recognized as if they were separate contracts over the performance periods of the individual elements or phases. Contract costs include only allocable, allowable and reasonable costs, as determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards for applicable U.S. Government contracts, and are included in cost of sales when incurred. The nature of these costs includes development engineering costs and product manufacturing costs including direct material, direct labor, other direct costs and indirect overhead costs. Contract profit is recorded as a result of the revenue recognized less costs incurred in any reporting period. Amounts representing performance incentives, penalties, contract claims or change orders are considered in estimating revenues, costs and profits when they can be reliably estimated and realization is considered probable. Revenue recognized on contracts for unresolved claims or unapproved contract change orders was not material for 2012, 2011 or 2010. For contracts with anticipated losses at completion, a provision for the entire amount of the estimated remaining loss is charged against income in the period in which the loss becomes known. Contract losses are determined considering all direct and indirect contract costs, exclusive of any selling, general or administrative cost allocations that are treated as period expenses. Loss reserves are more common on firm fixed-price contracts that involve, to varying degrees, the design and development of new and unique controls or control systems to meet the customers’ specifications.
As units Are Delivered Or Services Are Performed | As units are delivered or services are performed: In 2012, 68% of our sales were recognized as units were delivered or as service obligations were satisfied. Revenue is recognized when the risks and rewards of ownership and title to the product are transferred to the customer. When engineering or similar services are performed, revenue is recognized upon completion of the obligation including any delivery of engineering drawings or technical data. This method of revenue recognition is predominantly used within the Industrial Systems, Components and Medical Devices segments, as well as with aftermarket activity. Profits are recorded as costs are relieved from inventory and charged to cost of sales and as revenue is recognized. Inventory costs include all product manufacturing costs such as direct material, direct labor, other direct costs and indirect overhead cost allocations.
Shipping and Handling Cost | Shipping and Handling Costs: Shipping and handling costs are included in cost of sales.
Research and Development | Research and Development: Research and development costs are expensed as incurred and include salaries, benefits, consulting, material costs and depreciation.
Bid And Proposal Costs | Bid and Proposal Costs: Bid and proposal costs are expensed as incurred and classified as selling, general and administrative expenses.
Equity-Based Compensation | Equity-Based Compensation: Equity-based compensation expense is included in selling, general and administrative expenses.
Earnings Per Share | Earnings Per Share: Basic and diluted weighted-average shares outstanding are as follows:
|  | 2012 |  | 2011 |  | 2010
Basic weighted-average shares outstanding |  | 45,246,960 |  |  | 45,501,806 |  |  | 45,363,738 |
Dilutive effect of equity-based awards |  | 471,364 |  |  | 545,616 |  |  | 345,282 |
Diluted weighted-average shares outstanding |  | 45,718,324 |  |  | 46,047,422 |  |  | 45,709,020 |
Cash and Cash Equivalents | Cash and Cash Equivalents: All highly liquid investments with an original maturity of three months or less are considered cash equivalents.
Allowance For Doubtful Accounts | Allowance for Doubtful Accounts: The allowance for doubtful accounts is based on our assessment of the collectibility of customer accounts. The allowance is determined by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.
Inventories | Inventories: Inventories are stated at the lower-of-cost-or-market with cost determined on the first-in, first-out (FIFO) method of valuation.
Property, Plant And Equipment | Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated principally using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 15 years for building improvements, 12 years for furniture and fixtures, 10 years for machinery and equipment, 8 years for tooling and test equipment and 3 to 4 years for computer hardware. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the asset, whichever is shorter.
Goodwill | Goodwill: We test goodwill for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that indicate that the fair value of a reporting unit is likely to be below its carrying amount. We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or selected reporting units. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test instead of a qualitative test for any or all of our reporting units. Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. We use the discounted cash flow method to estimate the fair value of our reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating margins and cash flows, the terminal growth rate and the weighted-average cost of capital. If the carrying value of the reporting unit exceeds its fair value, goodwill is considered impaired and any loss must be measured. To determine the amount of the impairment loss, the implied fair value of goodwill is determined by assigning a fair value to all of the reporting unit's assets and liabilities, including any unrecognized intangible assets, as if the reporting unit had been acquired in a business combination at fair value. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss would be recognized in an amount equal to that excess. There were no impairment charges recorded in 2012, 2011 or 2010.
Acquired Intangible Assets | Acquired Intangible Assets: Acquired identifiable intangible assets are recorded at cost and are amortized over their estimated useful lives.
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets: Long-lived assets, including acquired identifiable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. We use undiscounted cash flows to determine whether impairment exists and measure any impairment loss using discounted cash flows. There were no impairment charges recorded in 2012, 2011 or 2010.
Product Warranties | Product Warranties: In the ordinary course of business, we warrant our products against defect in design, materials and workmanship typically over periods ranging from twelve to sixty months. We determine warranty reserves needed by product line based on historical experience and current facts and circumstances. Activity in the warranty accrual is summarized as follows:
|  | 2012 |  | 2011 |  | 2010
Warranty accrual at beginning of year |  | $ | 19,247 |  |  | $ | 14,856 |  |  | $ | 14,675 |
Additions from acquisitions |  | 233 |  |  | 120 |  |  | 213 |
Warranties issued during current year |  | 9,842 |  |  | 11,426 |  |  | 6,729 |
Adjustments to pre-existing warranties |  | (460 | ) |  | 713 |  |  | 186 |
Reductions for settling warranties |  | (10,016 | ) |  | (7,865 | ) |  | (6,831 | )
Foreign currency translation |  | 13 |  |  | (3 | ) |  | (116 | )
Warranty accrual at end of year |  | $ | 18,859 |  |  | $ | 19,247 |  |  | $ | 14,856 |
Financial Instruments | Financial Instruments: Our financial instruments consist primarily of cash and cash equivalents, receivables, notes payable, accounts payable, long-term debt, interest rate swaps and foreign currency forwards. The carrying values for our financial instruments approximate fair value with the exception at times of long-term debt. See Note 7, Indebtedness, for fair value of long-term debt. We do not hold or issue financial instruments for trading purposes. We carry derivative instruments on the balance sheet at fair value, determined by reference to quoted market prices. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. Our use of derivative instruments is generally limited to cash flow hedges of certain interest rate risks and minimizing foreign currency exposure on foreign currency transactions, which are typically designated in hedging relationships, and intercompany balances, which are not designated as hedging instruments. Cash flows resulting from forward contracts are accounted for as hedges of identifiable transactions or events and classified in the same category as the cash flows from the items being hedged.
Recent Accounting Pronouncements | Recent Accounting Pronouncements: In January 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2010-06, “Fair Value Measurements and Disclosures (ASC Topic 820) - Improving Disclosures About Fair Value Measurements.” This amendment requires separate disclosures about purchases, sales, issuances and settlements relating to Level 3 measurements. The disclosures are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. We adopted this standard in the first quarter of 2012. Other than requiring additional disclosures, the adoption of this guidance did not have a material impact on our consolidated financial statements. In December 2010, the FASB issued ASU No. 2010-28, “Intangibles - Goodwill and Other (ASC Topic 350) - When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts.” This amendment modifies the criteria for performing Step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts, and it requires performing Step 2 if qualitative factors indicate that it is more likely than not that an impairment exists. This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Any goodwill impairment resulting from the initial adoption of the amendments should be recorded as a cumulative effect adjustment to beginning retained earnings. Any goodwill impairments occurring after the initial adoption of the amendments should be included in earnings. We adopted this standard in the first quarter of 2012. The adoption of this guidance did not have a material impact on our financial statements. In December 2010, the FASB issued ASU No. 2010-29, “Business Combinations (ASC Topic 805) - Disclosure of Supplementary Pro Forma Information for Business Combinations.” This amendment expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. This amendment is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. Early adoption is permitted. We adopted this standard in the first quarter of 2012. Other than requiring additional disclosures, the adoption of this amendment did not have a material impact on our consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.” The amendments provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. The amendments also change certain fair value measurement principles and enhance the disclosure requirements, particularly for Level 3 fair value measurements. The amendments are effective during interim and annual periods beginning after December 15, 2011 and should be applied prospectively. Early adoption is not permitted. We adopted this standard during the second quarter of 2012. Other than requiring additional disclosures, the adoption of this amendment did not have a material impact on our consolidated financial statements. In July 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220) - Presentation of Comprehensive Income.” The amendment eliminates the option to present other comprehensive income and its components in the statement of stockholders' equity. The amendment requires all nonowner changes in stockholders' equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendment, which must be applied retrospectively, is effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. We adopted this standard during the second quarter of 2012. Other than requiring a change in the format of our financial statement presentation, the adoption of this amendment did not have a material impact on our consolidated financial statements. In December 2011, the FASB issued ASU No. 2011-12, “Comprehensive Income (Topic 220) - Deferral of the Effective Date for Amendments of 2011-05.” The amendment allows entities to continue to report reclassifications out of accumulated other comprehensive income consistent with the guidance in place prior to the issuance of ASU No. 2011-05. While the Board is considering the operational concerns about presentation requirements for reclassification adjustments, it stated that the deferral did not affect the requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements. The amendment, which must be applied retrospectively, is effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. We adopted this standard during the second quarter of 2012. The adoption of this amendment did not have a material impact on our consolidated financial statements.

- Definition Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 605 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SAB TOPIC 13.B.Q1) -URI http://asc.fasb.org/extlink&oid=6600647&loc=d3e214044-122780 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Accounting Principles Board Opinion (APB) -Number 22 -Paragraph 8, 12, 13 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
