	Nature of Business
	Spirit AeroSystems Holdings, Inc. ("Holdings" or the "Company") was incorporated in the state of Delaware on February 7, 2005, and commenced operations on June 17, 2005 through the acquisition of The Boeing Company's ("Boeing") operations in Wichita, Kansas, Tulsa, Oklahoma and McAlester, Oklahoma (the "Boeing Acquisition"). Holdings provides manufacturing and design expertise in a wide range of products and services for aircraft original equipment manufacturers and operators through its subsidiary, Spirit AeroSystems, Inc. ("Spirit"). Onex Corporation ("Onex") of Toronto, Canada and certain of its affiliates maintain majority voting power of Holdings. In April 2006, Holdings acquired the aerostructures division of BAE Systems (Operations) Limited ("BAE Aerostructures"), which builds structural components for Airbus, a division of Airbus Group NV ("Airbus") and Boeing. Prior to this acquisition, Holdings sold essentially all of its production to Boeing. Since Spirit's incorporation, the Company has expanded its customer base to include Sikorsky, Rolls-Royce, Gulfstream, Bombardier, Mitsubishi Aircraft Corporation, Southwest Airlines, United Airlines, American Airlines and Bell Helicopter. The Company has its headquarters in Wichita, Kansas, with manufacturing facilities in Tulsa and McAlester, Oklahoma; Prestwick, Scotland; Wichita, Kansas; Kinston, North Carolina and Subang, Malaysia. The Company has assembly facilities in Saint-Nazaire, France, and Chanute, Kansas.
	The Company is the majority participant in the Kansas Industrial Energy Supply Company ("KIESC"), a tenancy-in-common with other Wichita companies established to purchase natural gas.
	The Company participates in a joint venture, Taikoo Spirit AeroSystems Composite Co. Ltd. ("TSACCL"), of which Spirit's ownership interest is 31.5%. TSACCL was formed to develop and implement a state-of-the-art composite and metal bond component repair station in the Asia-Pacific region. On December 19, 2013, Spirit completed the sale of its interest in the Spirit-Progresstech joint venture.
	The accompanying consolidated financial statements include the Company's financial statements and the financial statements of its majority owned or controlled subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-K. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year financial statements and notes to conform to the 2013 presentation.

	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying consolidated financial statements include the Company's financial statements and the financial statements of its majority-owned subsidiaries and have been prepared in accordance with GAAP. Investments in business entities in which the Company does not have control, but has the ability to exercise influence over operating and financial policies, including TSACCL, are accounted for by the equity method. KIESC is fully consolidated as the Company owns 77.8% of the entity's equity. All intercompany balances and transactions have been eliminated in consolidation. The Company's U.K. subsidiary uses local currency, the British pound, as its functional currency; the Malaysian subsidiary uses the British pound and our Singapore subsidiary uses the Singapore dollar. All other foreign subsidiaries and branches use the U.S. dollar as their functional currency.
	As part of the monthly consolidation process, the functional currencies of the Company's international subsidiaries are translated to U.S. dollars using the end-of-month translation rate for balance sheet accounts and average period currency translation rates for revenue and income accounts.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates and assumptions. See Note 3, "Changes in Estimates," for details on current changes in estimates.
	The results of operations during fiscal 2013 include the favorable impact of cumulative catch-up adjustments relating to prior period revenues of $95.5 primarily associated with productivity and efficiency improvements on mature programs.
	The results of operations during fiscal 2012 include the favorable impact of cumulative catch-up adjustments relating to prior period revenues of $14.7 primarily associated with productivity and efficiency improvements on mature programs.
	The results of operations during fiscal 2011 include the favorable impact of cumulative catch-up adjustments relating to prior period revenues of $13.8 driven by productivity improvements, recognition of favorable performance as we closed out B737 and B777 contract blocks in the fourth quarter, and a lower forecast for our short-term incentive accrual, partially offset by increasing material costs in our Wing Systems segment.
	Revenues and Profit Recognition
	A significant portion of the Company's revenues are recognized under long-term, volume-based pricing contracts, requiring delivery of products over several years. The Company recognizes revenue under the contract method of accounting and records sales and profits on each contract in accordance with the percentage-of-completion method of accounting, primarily using the units-of-delivery method. The units-of-delivery method recognizes as revenue the contract price of units of a basic production product delivered during a period and as the cost of earned revenue the costs allocable to the delivered units. Costs allocable to undelivered units are reported in the balance sheet as inventory. The method is used in circumstances in which an entity produces units of a basic product under production-type contracts in a continuous or sequential production process to buyers' specifications. Recurring long-term production contracts are usually divided into contract blocks for this purpose, with each block treated as a separate contract for "units-of-delivery" production-type contract accounting purposes.
	The total quantity of production units to be delivered under a contract may be set as a single contract accounting block, or it can be split into multiple blocks. Unless the life of the contract is so long that it prevents reliable estimates, the entire contract will typically be set as the contract accounting block quantity. "Life-of-program" or "requirements-based" contracts often lead to continuing sales of more than twenty years. Since this is much longer than can be reliably estimated, Spirit uses parameters based on the contract facts and circumstances to determine the length of the contract block. This analysis includes: considering the customer's firm orders, internal assessment of the market, reliability of cost estimates, potential segmentation of non-recurring elements of the contract, and other factors. Contract block sizes may also be determined based on certain contractual terms such as pricing renegotiation dates, such that certain contract blocks may use an approximate date instead of a defined unit quantity in order to increase the ability to estimate accurately given that the renegotiated pricing is unknown for the planning block. Shorter contract blocks for mature, ongoing programs are common due to the presence of recent cost history and probable forecast accuracy. Mature program contract blocks tend to be approximately two years in length. Initial contract blocks often require a longer time period and a greater number of units in order to take into account the higher cost of early units due to a steeper experience curve and pre-production design costs. Initial contract blocks on new programs can extend up to ten years or longer. As these programs mature, costs stabilize and efficiencies are realized, subsequent contract block length shortens to take into account the steady state of the continuing production.
	Revenues from non-recurring design work are recognized based on substantive milestones or use of the cost-to-cost method, that are indicative of our progress toward completion depending on facts and circumstances. We follow the requirements of FASB authoritative guidance on accounting for the performance of construction-type and certain production-type contracts (the contract method of accounting), and use the cumulative catch-up method in accounting for revisions in estimates. Under the cumulative catch-up method, the impacts of revisions in estimates are recognized immediately when changes in estimated contract profitability become known.
	A profit rate is estimated based on the difference between total revenues and total costs over a contract block. Total revenues at any given time include actual historical revenues up to that time plus future estimated revenues. Total costs at any given time include actual historical costs up to that time plus future estimated costs. Estimated revenues include negotiated or expected values for units delivered, estimates of probable recoveries asserted against the customer for changes in specifications, price adjustments for contract and volume changes, escalation and assumed but currently unnegotiated price increases for derivative models. Costs include the estimated cost of certain pre-production efforts (including non-recurring engineering and planning subsequent to completion of final design) plus the estimated cost of manufacturing a specified number of production units. Estimates take into account assumptions related to future labor performance and rates, and projections related to material and overhead costs including expected "learning curve" cost reductions over the term of the contract. Estimated revenues and costs also take into account the expected impact of specific contingencies that we believe are probable.
	Estimates of revenues and costs for our contract blocks span a period of multiple years and are based on a substantial number of underlying assumptions. We believe that the underlying assumptions are sufficiently reliable to provide a reasonable estimate of the profit to be generated. However, due to the significant length of time over which revenue streams will be generated, the variability of the revenue and cost streams can be significant if the assumptions change. Estimates of profit margins for contract accounting blocks are typically reviewed on a quarterly basis. Assuming the initial estimates of sales and costs under the contract block are accurate, the percentage-of-completion method results in the profit margin being recorded evenly as revenue is recognized under the contract block. Changes in these underlying estimates due to revisions in sales and cost estimates may result in profit margins being recognized unevenly over a contract block as such changes are accounted for on a cumulative basis in the period estimates are revised, which we refer to as cumulative catch-up adjustments. Our Estimate At Completion estimating process is not solely an accounting process, but is instead an integrated part of the management of our business, involving numerous personnel in our planning, production control, contracts, cost management, supply chain and program and business management functions. In 2013, we recorded positive cumulative catch-up adjustments for periods prior to 2013 of $60.1, $30.0 and $5.4 for the Fuselage, Propulsion and Wing Segments, respectively. When the current estimates of total contract revenue and total contract cost indicate a loss, a provision for the entire loss on the contract, known as a forward loss charge, is recorded to cost of sales in the period in which they become evident. In 2013, we recognized $1,133.3 in forward losses.
	For revenues not recognized under the contract method of accounting, the Company recognizes revenues from the sale of products at the point of passage of title, which is generally at the time of shipment. Shipping and handling costs are included in cost of sales. Revenues earned from providing maintenance services, including any contracted research and development, are recognized when the service is complete or other contractual milestones are attained. Revenues from non-recurring design work are recognized based on substantive milestones that are indicative of our progress toward completion. Non-recurring revenues, which are derived primarily from engineering and design efforts, were $255.6, $239.4 and $222.0 for each of the twelve month periods ending December 31, 2013, December 31, 2012 and December 31, 2011, respectively.
	As required by FASB authoritative guidance related to accounting for consideration given by a vendor to a customer, under an agreement with Airbus, certain payments are amortized as a reduction to revenues on units delivered. Additionally, in 2012 we began making certain payments related to our Gulfstream G280 and G650 programs. The Company recognized $28.6 and $51.1 as a reduction to net revenues for the periods ended December 31, 2013 and December 31, 2012, respectively.
	Developments on Our New and Maturing Programs
	A significant portion of the Company's future revenues is expected to be derived from new and maturing programs, most notably the B787, A350 XWB, G650 and G280, on which we may be contracted to provide design and engineering services, recurring production, or both. There are several risks inherent to such new and maturing programs. In the design and engineering phase, we may incur costs in excess of our forecasts due to several factors, including cost overruns, customer-directed change orders and delays in the overall program. We may also incur higher than expected recurring production costs, which may be caused by a variety of factors, including the future impact of engineering changes (or other change orders) or our inability to secure contracts with our suppliers at projected cost levels. Our ability to recover these excess costs from the customer will depend on several factors, including our rights under our contracts for the new and maturing programs. In determining our profits and losses in accordance with the percentage-of-completion method of contract accounting, we are required to make significant assumptions regarding our future costs and revenues, as well as the estimated number of units to be manufactured under the contract and other variables. We continually review and update our assumptions based on market trends and our most recent experience. If we make material changes to our assumptions, such as a reduction in the estimated number of units to be produced under the contract (which could be caused by emerging market trends or other factors), an increase in future production costs or a change in the recoverability of increased design or production costs, we may experience negative cumulative catch-up adjustments related to revenues previously recognized. In some cases, we may recognize forward loss amounts.
	Research and Development
	Research and development includes costs incurred for experimentation, design and testing and are expensed as incurred as required under FASB authoritative guidance pertaining to accounting for research and development costs.
	Joint Venture
	The value of the Company's 31.5% ownership interest in Taikoo Spirit AeroSystems Composite Co. Ltd. totaled $1.4 at December 31, 2013 and is accounted for under the equity method of accounting.
	Cash and Cash Equivalents
	Cash and cash equivalents represent all highly liquid investments with original maturities of three months or less.
	Accounts Receivable
	Accounts receivable are recorded at the invoiced amount and do not bear interest. Consistent with industry practice, the Company classifies unbilled receivables related to contracts accounted for under the long-term contract method of accounting, as current. The Company determines an allowance for doubtful accounts based on a review of outstanding receivables. Account balances are charged off against the allowance after the potential for recovery is considered remote. The Company's allowance for doubtful accounts was approximately $0.2 and $4.3 at December 31, 2013 and December 31, 2012, respectively.
	Accounts receivable, net includes unbilled receivables on long-term aerospace contracts, comprised principally of revenue recognized on contracts for which amounts were earned but not contractually billable as of the balance sheet date, or amounts earned in which the recovery will occur over the term of the contract, which could exceed one year.
	Inventory
	Raw materials are stated at lower of cost (principally on an actual or average cost basis) or market. Inventoried costs attributed to units delivered under long-term contracts are based on the estimated average cost of all units expected to be produced and are determined under the learning curve concept which anticipates a predictable decrease in unit costs as tasks and production techniques become more efficient through repetition and supply chain costs are reduced as contracts are negotiated and design changes result in lower cost. This usually results in an increase in inventory (referred to as "excess-over-average" or "deferred production costs") during the early years of a contract. These costs are deferred only to the extent the amount of actual or expected excess-over-average is reasonably expected to be fully offset by lower-than-average costs in future periods of a contract. If in-process inventory plus estimated costs to complete a specific contract exceed the actual plus anticipated remaining sales value of such contract, such excess is charged to cost of sales in the period the loss becomes known, thus reducing inventory to estimated realizable value. Costs in inventory include amounts relating to contracts with long production cycles, some of which are not expected to be realized within one year.
	The Company reviews its general stock materials and spare parts inventory each quarter to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends and expected production usage. Impaired inventories are written off to work-in-process in the period identified.
	Total inventory includes deferred production costs for the excess of production costs over the estimated average cost per ship set, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per ship set for units delivered under the current production blocks. Recovery of excess over average deferred production costs is dependent on the number of ship sets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. Work-in-process inventory also includes non-recurring production costs. Non-recurring production costs include design and engineering costs and test articles.
	Finished goods inventory is stated at its estimated average per unit cost based on all units expected to be produced.
	Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant customer directed work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a certain number of ship set deliveries.
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is applied using a straight-line method over the useful lives of the respective assets as described in the following table:
		Estimated Useful Life
	Land improvements	20 years
	Buildings	45 years
	Machinery and equipment	3-20 years
	Tooling — Airplane program — B787, Rolls-Royce	5-20 years
	Tooling — Airplane program — all others	2-10 years
	Capitalized software	3-7 years
	We capitalize certain costs, such as software coding, installation and testing, that are incurred to purchase or to create and implement internal-use computer software in accordance with FASB authoritative guidance pertaining to capitalization of cost for internal-use software. Our capitalization policy includes specifications that the software must have a service life greater than one year, is legally and substantially owned by Spirit, and has an acquisition cost of greater than $0.1.
	Intangible Assets
	Intangible assets are initially recorded at estimated fair value and are comprised of patents, favorable leasehold interests, and customer relationships that are amortized on a straight-line basis over their estimated useful lives, ranging from 6 to 16 years for patents, 14 to 24 years for favorable leasehold interests, and 8 years for customer relationships.
	Impairment or Disposal of Long-Lived Assets and Goodwill
	Spirit reviews capital and amortizing intangible assets (long-lived assets) for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable in accordance with FASB authoritative guidance on accounting for the impairment or disposal of long-lived assets. Under the standard, assets must be classified as either held-for-use or available-for-sale. An impairment loss is recognized when the carrying amount of an asset that is held for use exceeds the projected undiscounted future net cash flows expected from its use and disposal, and is measured as the amount by which the carrying amount of the asset exceeds its fair value, which is measured by discounted cash flows when quoted market prices are not available. For assets available-for-sale, an impairment loss is recognized when the carrying amount exceeds the fair value less cost to sell. The Company performs an annual impairment test for goodwill in the fourth quarter of each year, in accordance with FASB authoritative guidance pertaining to goodwill and other intangible assets, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below current value. Recent impairment testing has indicated no need for impairment.
	Deferred Financing Costs
	Costs relating to long-term debt are deferred and included in other long-term assets. These costs are amortized over the term of the related debt or debt facilities, and are included as a component of interest expense.
	Derivative Instruments and Hedging Activity
	We use derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates and interest rates. To account for our derivative financial instruments, we follow the FASB guidance on accounting for derivatives and hedges. Derivative financial instruments are recognized on the Consolidated Balance Sheets as either assets or liabilities and are measured at fair value. Changes in fair value of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedge transaction, and if it is, the type of hedge transaction. Gains and losses on derivative instruments reported in other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item or when the hedge is no longer effective. We present the cash flows associated with our derivatives as a component of the operating or investing sections of the statement of cash flows. Our use of derivatives has generally been limited to interest rate swaps and foreign currency forward contracts. The Company enters into foreign currency forward contracts to reduce the risks associated with the changes in foreign exchange rates on sales and cost of sales denominated in currencies other than the entities' functional currency.
	Fair Value of Financial Instruments
	Financial instruments are measured in accordance with FASB authoritative guidance related to fair value measurements. This guidance clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about fair value measurements. See Note 12, "Fair Value Measurements."
	Income Taxes
	Income taxes are accounted for in accordance with FASB authoritative guidance on accounting for income taxes. Deferred income tax assets and liabilities are recognized for the future income tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to reduce deferred income tax assets to an amount that in management's opinion will ultimately be realized. Tax rate changes impacting these assets and liabilities are recognized in the period during which the rate change occurs.
	We record an income tax expense or benefit based on the net income earned or net loss incurred in each tax jurisdiction and at the tax rate applicable to that income or loss. In the ordinary course of business, there are transactions for which the ultimate tax outcome is uncertain. These uncertainties are accounted for in accordance with FASB authoritative guidance on accounting for the uncertainty in income taxes. The final tax outcome for these matters may be different than management's original estimates made in determining the income tax provision. A change to these estimates could impact the effective tax rate and net income or loss in subsequent periods. We use the flow-through accounting method for tax credits. Under this method, tax credits reduce income tax expense.
	Stock-Based Compensation and Other Share-Based Payments
	Many of the Company's employees are participants in various stock compensation plans. The Company accounts for stock option plans, restricted share plans and other stock-based payments in accordance with FASB authoritative guidance pertaining to share-based payment. The expense attributable to the Company's employees is recognized over the period the amounts are earned and vested, as described in Note 18 "Stock Compensation."
	Service and Product Warranties and Extraordinary Rework
	Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These estimates are established using historical information on the nature, frequency and average cost of warranty claims.
	The following is a roll forward for the warranty and extraordinary rework provision as of December 31, 2013 and December 31, 2012:
		2013			2012
Balance, January 1	$	30.9		$	19.6
Charges to costs and expenses	38.3			12
Write-offs, net of recoveries	(0.6		)	(0.9		)

Changes in Estimates	'
	Changes in Estimates
	The Company’s long-term contract estimates are based on estimated contract revenues and related costs over the Company’s current contract blocks.  Estimated contract revenues are generally not subject to significant revisions as most of the Company’s contracts are fixed price and known at the inception of the contract; however, the contract cost elements of these estimates change frequently as the programs mature and that has historically been the primary driver of changes in our estimates.   Contract costs are estimated based on actual costs incurred to date and an estimate of remaining costs over the current contract block, which can extend for multiple years.  During the early phases of our program contracts, the future cost estimates are subject to significant variability and are based on numerous assumptions and judgments which require management to use its historical experience on similar programs until aircraft programs are type certified; low rate production is achieved; production processes mature; supply chain partners are contracted; and unit costs stabilize; which typically results in assumptions that costs will improve over the life of the contract block. This learning curve concept is typical in our industry; however, the level of design change and time spent in low rate production that was anticipated when we initially established these curves has been significantly exceeded as original delivery schedules have been delayed and engineering changes have continued. During 2013 and 2012, a combination of events occurred that resulted in significant changes in estimates on several new and maturing programs, resulting in forward losses being recorded on some of these programs. The following is a summary of those events.
	2013 Changes in Estimates
	Performance Issues - A350 XWB
	Our A350 XWB fuselage recurring program has experienced various production inefficiencies mostly driven by early development discovery and engineering change to the aircraft design, as well as higher test and transportation costs. Airbus is assisting us as we work through these issues and has provided additional resources to work alongside our personnel. In the third quarter of 2013, we recorded a forward loss of $78.6 for the A350 XWB fuselage recurring contract due to these production inefficiencies. There continues to be risk of additional forward loss associated with the recurring contract as we work through production issues.
	Non-Recurring Contract Agreements - A350 XWB
	In September and October of 2013 we agreed with Airbus on the work scope for the design and tooling related to the -1000 derivative of the A350 XWB fuselage and wing contracts, respectively. Based on current estimates, the agreement for the non-recurring phase of the -1000 derivative fuselage resulted in a $32.7 forward loss, which was recorded in the third quarter of 2013. There is a risk of additional forward loss if we do not successfully execute the design and engineering change process as projected.
	Supply Chain Cost Reductions - G280 and G650
	At the time we recorded the forward loss charges on the Gulfstream G280 and G650 programs in the third quarter of 2012, we had included in the respective estimates at completion significant cost reductions primarily related to sourcing costs between 2015 and 2018. These amounts were based on the experience of the supply chain team and operational management. During the second quarter of 2013, it became apparent that a substantial portion of the total cost savings included in the contract estimates for each program would not be realized. This determination was based on a number of changing conditions and new developments including an assessment of our actual experience with our customers regarding their receptiveness to proposed changes, completion of our detailed part analysis during the second quarter of 2013 as part of our effort to project future sourcing costs and our inability to achieve estimated supplier price reductions via negotiations with suppliers.
	Labor Estimates- Tulsa Facility
	The labor cost forecasts within the contract estimates for the G280, G650 and Boeing B787 are based on certain assumptions, including the level of disruption expected in the future. In our contract estimates through the first quarter of 2013, we assumed that certain disruptions to the manufacturing line caused by (i) supplier quality issues and late deliveries, (ii) customer inspections occurring in our facilities and (iii) our own manufacturing quality issues would be resolved by the middle of 2013. During the second quarter of 2013, key performance dates were missed, and we extended the expected period of time during which these issues would be resolved in our assumptions for our contract estimates. As a result, we experienced higher actual costs as well as significant increases to forecasted costs, resulting in additional forward losses recognized on all of these programs in the second and fourth quarters of 2013.
	Contractual Items - G650
	As we worked with Gulfstream to meet its production demand, we negotiated a temporary transfer of a portion of our work scope to Gulfstream for completion. In the second quarter of 2013, due to the effect of continued production challenges on our forecasted ability to achieve scheduled deliveries, we changed our assumptions to extend the duration of the work transfer and updated our estimates regarding this temporarily transferred work scope which is accounted for as a reduction in forecasted revenue. As described in more detail in Note 21, "Commitments, Contingencies and Guarantees," we instituted a demand for arbitration against Gulfstream to resolve certain contractual disputes primarily related to engineering changes made by Gulfstream and the impact of those changes to weight and delivery schedules as well as for incomplete payments to Spirit. We continually assess these contractual items and adjust our estimates as appropriate each quarter. Changes in these particular estimates resulted in additional forward loss recognized on the G650 in the second quarter of 2013.
	B787 program
	As we move into higher rates of production, our performance at the current contracted price depends on our being able to achieve production cost reductions as we gain production experience. During the second quarter of 2013, we continued to experience production inefficiencies at our Tulsa facility as we transitioned to production on the B787-9 derivative, which drove forward losses of $37.3 on the B787 wing program. Additionally in the fourth quarter of 2013, we revised our estimates of the amount of near-term achievable cost reductions for the B787 program based on cost savings ideas generated, the maturity of these ideas and the expected realization for the programs. This change in cost savings estimates drove a forward loss of $384.7 in the fourth quarter of 2013.
	2012 Changes in Estimates
	Performance Issues-Tulsa Facility
	The Company’s Tulsa facility has significant work content on three of the development programs (B787, G280, G650). The multiple complex development programs at this facility have created various performance issues that have resulted in previous changes to our contract estimates on these development programs.
	The performance issues at the Tulsa facility were magnified in the third quarter of 2012 when the Company implemented a recovery plan which would bring the company current for its B787 wing components. The Company began implementing the recovery plan during late July 2012 which resulted in the addition of significant additional resources to meet delivery schedules. As the Company was implementing the recovery plan, it became clear during the third quarter estimation process that the remediation would have a significant impact on the future cost curves due to significant amounts of additional headcount and disruption.
	Type Certification
	On September 4 and 7, 2012, Gulfstream received type certification on the G280 and G650 aircraft, respectively. These type certifications impact three of the Company’s development programs, G280, G650 and BR725 (the engine nacelle on the G650). Type certification is a significant program milestone for commercial aerospace products as it represents the airworthiness authority’s approval of the completion and functionality of engineering design and the ability of the aircraft to enter into service, and leads directly to the commencement of full rate production. However, following type certification the ability to redesign for cost is significantly less if no derivative aircraft design is planned. We currently have no plans for derivative models, making redesign for cost improvements difficult after type certification.
	The pace of cost improvements was not keeping up with projected learning curves particularly related to redesign opportunities and as all three programs are preparing to enter full rate production, we revised our estimates to reflect higher costs.
	Decision on Work Package Transfers
	Given certain challenges of new programs at the Company’s Kinston, North Carolina site and the fact that our newest facility in Chanute, Kansas was in the process of multiple work package transfers during the third quarter, the Company decided to delay the transfer of any additional work packages into these facilities. Overall, this had a significant impact on the BR725 program and the timing of anticipated cost reduction from the planned transfer of work content to lower-cost facilities.
	Finalization of Supplier Contracts
	During the early phases of our development programs, the Company will frequently procure small quantities of required sub-assemblies and parts from our suppliers. This practice generally forces us to pay higher unit prices for these sub-assemblies and parts, but allows us flexibility in evaluating supplier performance and quality as well as addressing design changes that frequently occur during the early phases of these development programs. Once design changes subside, we will generally contract on a longer-term basis with our suppliers which allows us to experience more favorable supply chain pricing.
	The Company has been successful in negotiating lower costs with suppliers on most of these development programs; however, these costs are not as low as original estimates. This pressure on supply chain cost runs across all of our development programs. As Boeing and Airbus have increased production rates on existing commercial programs, our suppliers have limited capacity to deal with even modest rate increases on our business jet programs. In addition, the capacity constraint in our supply base has prevented us from off-loading to the supply chain certain work we currently perform in-house. As a result of higher current costs which have exceeded estimates and recent negotiations with suppliers, the Company has revised supplier costs across several of the development programs.
	New and Maturing Programs Summary Performance
	Due primarily to the events described above in this Note 3, in 2013 we recorded forward loss charges of $78.6 on the recurring A350 XWB Section 15, $32.7 on the non-recurring A350 XWB Section 15, $240.9 on the G280 program, $288.3 on the G650 program and $422.0 on the B787 program. Additionally, due to program performance and/or changes in estimates in 2013 we recorded forward loss charges of $41.1, $16.4 and $21.7 on the B747, B767 and Rolls-Royce BR725 programs, respectively. The Rolls-Royce BR725 program also recorded a reduction of forward loss charges of $8.4 for a total net forward loss of $13.3 in 2013. These amounts were recorded within the Company’s results of operations as part of cost of goods sold as well as on the condensed consolidated balance sheet as forward loss provisions within inventory to the extent each program’s inventory balance was sufficient to absorb the charge. In the case that program inventory was not sufficient to absorb the full amount of a charge, the remainder was classified as a current liability.
	Due to performance, type certification, work package transfers and finalization of supplier contracts, as well as other events, for the twelve months ended December 31, 2012, we recorded forward loss charges of $184.0 on the Boeing 787, $162.5 on the Gulfstream G650, $151.0 on the Rolls-Royce BR725, $118.8 on the Gulfstream G280, $8.9 on the Airbus A350 XWB non-recurring wing, $11.5 on the Boeing 747-8 program and $8.0 on the B767 program. These amounts are recorded on the condensed consolidated balance sheet as forward loss provisions within inventory.
	Our consolidated net adjustments for costs related to the aforementioned changes in estimates and other circumstances for the twelve months ended December 31, 2013 and December 31, 2012, decreased operating profit, before income taxes, by approximately $1,133.3 and $644.7, respectively. These adjustments decreased net earnings for the twelve months ended December 31, 2013 and December 31, 2012 by approximately $713.0 ($5.04 per share) and $412.0 ($2.88 per share), respectively.

	Impact from Severe Weather Event
	On April 14, 2012, during a severe weather event, the Company's Wichita, Kansas facility, which includes its headquarters and manufacturing facilities for all Boeing models as well as operations for maintenance, repair and overhaul support and services (MRO), was hit by a tornado which caused significant damage to many buildings, disrupted utilities and resulted in complete suspension of production for eight days. The Company's work-in-process and production equipment generally remained intact, and the Company resumed production on April 23, 2012, although some inefficiencies continued thereafter as a result of the damage and repair efforts.
	As of December 31, 2012, the Company had received a total of $234.9 in insurance payments based on estimated losses incurred as a result of the April 14, 2012 tornado. In accordance with its credit agreement, the Company provided a certificate to its lenders indicating that all net proceeds received in connection with the destruction caused by the April 14th tornado would be used for repair, replacement or restoration at the Wichita facility.
	On October 19, 2012, the Company reached an agreement with its insurers on a final settlement for all claims relating to the April 14, 2012 severe weather event. Under the terms of this settlement the insurers agreed to pay to the Company $234.9 (including payments previously made) to resolve all property damage, clean-up and recovery costs related to the severe weather event as well as all expenses incurred to make up for the interruption of production and to reduce further disruptions. Under the settlement agreement, the Company assumes all further risk involving the severe weather event on April 14, 2012.
	For the twelve months ended December 31, 2012, the Company recorded a net gain of $146.2 under severe weather event, which represents the settlement amount of $234.9 less cumulative charges of $88.7, which primarily relates to repair, clean-up, asset impairment and incremental freight, labor and warehousing costs to restore normal operations.
	During the twelve months ended December 31, 2013 and December 31, 2012, the Company recorded an impairment charge of zero and $0.2, respectively, for certain assets that were destroyed during the severe weather event. Any future impairment charges are expected to be immaterial.
	During the twelve months ended December 31, 2013, the Company recorded expenses of $30.3 under severe weather event, which represents continuing incremental freight, warehousing and other costs which are recorded as incurred.

	Accounts receivable, net includes unbilled receivables on long-term aerospace contracts, comprised principally of revenue recognized on contracts for which amounts were earned but not contractually billable as of the balance sheet date, or amounts earned in which the recovery will occur over the term of the contract, which could exceed one year.
	Also included in accounts receivable are amounts held in retainage which, as of December 31, 2013, are all related to Gulfstream and represent amounts due on G650 deliveries from 2010 through the third quarter of 2013. As described in more detail in Note 22, "Commitments, Contingencies and Guarantees," in August 2013, the Company instituted a demand for arbitration against Gulfstream Aerospace Corporation, seeking damages from Gulfstream for its incomplete payments to Spirit, as well as other damages and relief. Gulfstream counterclaimed against Spirit in the arbitration, seeking liquidated damages for delayed deliveries of wings, as well as other damages and relief.  While we believe that the short-paid amount is collectible, if we are unable to collect this amount or if it becomes part of an overall settlement or arbitration award, recognition of additional forward losses on the G650 program could be required and the future cash flows of the Company could be significantly impacted.
	On May 3, 2012, one of our customers, Hawker Beechcraft, filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code. Subsequent to the bankruptcy filing, the Company reserved the remaining balance of its $3.5 receivable from Hawker in 2012. This balance was written off in 2013.

	_______________________________________
	-1	For December 31, 2012, deferred production of $1,173.8 was reclassified from work-in-process to conform to current year presentation.
	-2	For December 31, 2013, $17.9 of work-in-process was reclassified to capitalized pre-prodution.
	Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant unfunded statement of work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a certain number of ship set deliveries and the Company believes these amounts will be fully recovered.
	Total inventory includes deferred production costs for the excess of production costs over the estimated average cost per ship set, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per ship set for units delivered under the current production blocks. Recovery of excess-over-average deferred production costs is dependent on the number of ship sets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. The Company believes these amounts will be fully recovered. Sales significantly under estimates or costs significantly over estimates could result in the realization of losses on these contracts in future periods.
	Non-recurring production costs include design and engineering costs and test articles.

	_______________________________________
	-1	Forward loss charges taken since January 1, 2012 on blocks that have not closed.
	-2	Forward loss charges taken through December 31, 2011 were reflected within capitalized pre-production and inventory for the respective programs and are therefore not reflected as part of the Forward Loss Provision figure presented. The cumulative forward loss charges, net of contract liabilities, through December 31, 2013 on open blocks are $123.8, $463.1 and $29.0 for the A350 XWB, G280 and Sikorsky programs, respectively.
	-3	Forward loss provision of $41.1 recorded on the fuselage portion of the B747 program in 2013 included $21.2 of charges on the subsequent planning block. The total provision exceeded the inventory balance which resulted in a contract liability of $3.9 which will be reduced as additional contact costs are incurred.
	-4	Forward loss provision of $11.6 recorded in 2013 on the B767 program of which $7.5 related to propulsion which exceeded the inventory balance for the propulsion portion of the program. The excess of charge over program inventory was classified as a contract liability of $5.8 which will be reduced as additional contract costs are incurred. Forward loss provision of $8.0 recorded on the B767 program in the fourth quarter of 2012 exceeded the total inventory balance. The excess of the charge over program inventory was classified as a contract liability of $1.5 as of December 31, 2012 and was reduced to zero as additional inventory was generated as of June 27, 2013.
	-5	Forward loss provision of $32.7 recorded on the non-recurring fuselage portion of the A350-1000 XWB program in 2013 exceeded the total inventory balance. The excess of the charge over the program inventory is classified as a contract liability of $7.7, reduced to zero as additional inventory was generated as of December 31, 2013. This liability was reported in other current liabilities and was absorbed back into the forward loss category of inventory as inventory on the non-recurring portion of the program increased. In 2013, non-recurring in the amount of $17.9 was reclassified to capitalized pre-prodution.
	-6	Forward loss provision of $240.9 recorded in 2013 exceeded the total inventory balance. The excess of the charge over program inventory is classified as a contract liability. The total contract liability as of December 31, 2013 is $74.2. This contract liability is reported in other current liabilities. This liability will flow back into the forward loss category of inventory as inventory on the program increases.
	-7	Forward loss provision of $151.0 recorded in 2012 exceeded the total inventory balance. The excess of the charge over program inventory is classified as a contract liability. In 2013 a forward loss provision of $21.7 and forward loss reduction of $8.4 was recorded, the net of which increased the contract liability from 2012. The total contract liability is $36.7 as of December 31, 2013. This contract liability is reported in other current liabilities. This liability will flow back into the forward loss category of inventory as inventory on the program increases.
	-8	Includes over-applied and under-applied overhead.
	The following is a roll forward of the capitalized pre-production costs included in the inventory balance at December 31, 2013 and December 31, 2012:
		2013				2012
Balance, January 1	$	524.6			$	553.2
Charges to costs and expenses	(64.8		)		(59.7		)
Capitalized costs (1)	26.4				31.1
Balance, December 31	$	486.2			$	524.6
_______________________________________
-1	Capitalized costs in 2013 primarily due to reclassification of $17.9 from non-recurring to capitalized pre-production.
The following is a roll forward of the deferred production included in the inventory balance at December 31, 2013 and December 31, 2012:
	2013(1)				2012(1)

Exchange rate	5.8				3.1
Balance, December 31	$	1,661.20			$	1,173.80
_______________________________________
-1	Increases in deferred production are driven primarily by new and maturing programs.
Significant amortization of capitalized pre-production and deferred production inventory will occur over the following contract blocks:
	Contract Block			Orders(1)
	Quantity
B787	500			916
A350 XWB	400			812
G280	250			85
G650	350			145
Rolls-Royce	350			136
_______________________________________
-1	Orders are from the published firm-order backlogs of Airbus and Boeing. For all other programs, orders represent purchase orders received from OEMs and are not reflective of OEM sales backlog. Orders reported are total block orders, including delivered units.
Current block deliveries are as follows:
Model	Current Block
	Deliveries
B787	164
A350 XWB	11
Business/Regional Jets	217
Contract block quantity is projected to fully absorb the balance of deferred production inventory. Capitalized pre-production and deferred production inventories are at risk to the extent that we do not achieve the orders in the forecasted blocks or if future actual costs exceed current projected estimates, as those categories of inventory are recoverable over future deliveries. In the case of capitalized pre-production this may be over multiple blocks. Should orders not materialize in future periods to fulfill the block, potential forward loss charges may be necessary to the extent the final delivered quantity does not absorb deferred inventory costs.

	Milestone payments.    Milestone payments are recognized as revenue when milestones are deemed to be substantive and are achieved. A substantive milestone is one that is based on successful performance by the Company and not solely contingent upon the passage of time or performance by another party. Milestone payments collected in advance that have significant future performance obligations are presented as advance payments or deferred revenue, and are recognized when the milestone is achieved.
	As part of our ongoing participation in the B787-9 program, we received research and development milestone payments of $18.3 and $30.0 for the twelve months ended December 31, 2013 and December 31, 2012, respectively. Revenue and cost associated with the performance of the research and development are included in program revenue and costs. We expect to receive additional payments related to research and development on this program. These additional payments remain to be negotiated as of December 31, 2013.

	Advance Payments and Deferred Revenue/Credits
	Advance payments.    Advance payments are those payments made to Spirit by third parties in contemplation of the future performance of services, receipt of goods, incurrence of expenditures, or for other assets to be provided by Spirit on a contract and are repayable if such obligation is not satisfied. The amount of advance payments to be recovered against units expected to be delivered within a year is classified as a short-term liability, with the balance of the unliquidated advance payments classified as a long-term liability.
	In March 2012, we signed a Memorandum of Agreement with Airbus providing for us to receive advance payments in 2012. The advance payments will be offset against the recurring price of A350 XWB ship sets invoiced by Spirit at a rate of $1.25 per ship set. We received zero and $250.0 in the twelve months ended December 31, 2013 and December 31, 2012, respectively.
	Deferred revenue/credits.    Deferred revenue/credits generally consist of nonrefundable amounts received in advance of revenue being earned for specific contractual deliverables. These payments are classified as deferred revenue/credits when received and recognized as revenue as the production units are delivered.

Government Grants	'
	Government Grants
	We received grants in the form of government funding for a portion of the site construction and other specific capital asset cost at our Kinston, North Carolina and Subang, Malaysia sites. Deferred grant income is being amortized as a reduction to production cost. This amortization is based on specific terms associated with the different grants. In North Carolina, the deferred grant income related to the capital investment criteria, which represents half of the grant, is being amortized over the lives of the assets purchased to satisfy the capital investment performance criteria. The other half of the deferred grant income is being amortized over a 10-year period in a manner consistent with the job performance criteria. In Malaysia, the deferred grant income is being amortized based on the lives of the eligible assets constructed with the grant funds as there are no performance criteria. The value recorded within property, plant and equipment prior to amortization, including foreign exchange rate changes, related to the use of grant funds in North Carolina and Malaysia was $153.8 and $148.7 as of December 31, 2013 and December 31, 2012, respectively.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	FASB's authoritative guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance discloses three levels of inputs that may be used to measure fair value:
	Level 1		Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market.
	Level 2		Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Observable inputs, such as current and forward interest rates and foreign exchange rates, are used in determining the fair value of our interest rate swaps and foreign currency hedge contracts.
	Level 3		Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

	The fair value of the interest rate swaps and foreign currency hedge contracts are determined by using mark-to-market reports generated for each derivative and evaluated for counterparty risk. In the case of the interest rate swaps, the Company evaluated its counterparty risk using credit default swaps, historical default rates and credit spreads.
	The Company's long-term debt consists of a senior secured term loan, senior unsecured notes, and the Malaysian term loan. The estimated fair value of our debt obligations is based on the quoted market prices for such obligations or the historical default rate for debt with similar credit ratings.

Derivative and Hedging Activities

The Company enters into interest rate swap agreements to reduce its exposure to the variable rate portion of its long-term debt. The Company could enter into foreign currency hedge contracts to reduce the risks associated with the changes in foreign exchange rates on sales and cost of sales denominated in currencies other than the entities' functional currency. Any gains or losses on hedges are included in earnings when the underlying transaction that was hedged occurs. The Company does not use contracts for speculative or trading purposes. On the inception date, the Company designates a derivative contract as either a fair value or cash flow hedge in accordance with FASB guidance on accounting for derivatives and hedges and links the contract to either a specific asset or liability on the balance sheet, or to forecasted commitments or transactions. The Company formally documents the hedging relationship between the hedging instrument and the hedged item, as well as its risk-management objective and strategy for undertaking the hedge, the nature of the risk being hedged, how the hedging instrument's effectiveness in offsetting the hedged risk will be assessed and a description of the method of measuring ineffectiveness. The Company also formally assesses, both at the hedge's inception and on a quarterly basis, whether the derivative item is effective in offsetting changes in fair value or cash flows.

Changes in the fair value of derivative instruments considered to be effective hedges are reported in other comprehensive income, net of tax. In the case of interest rate swaps, amounts are subsequently reclassified into interest expense as a yield adjustment of the hedged interest payments in the same period in which the related interest affects earnings. If the actual interest rate on the fixed rate portion of debt is less than LIBOR, the monies received are recorded as an offset to interest expense. Conversely, if the actual interest rate on the fixed rate portion of debt is greater than LIBOR, then the Company pays the difference, which is recorded to interest expense. Reclassifications of any amounts related to foreign currency hedge contracts would be recorded to earnings in the same period in which the underlying transaction occurs. Any change in the fair value resulting from ineffectiveness is immediately recognized in earnings.

The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. The Company has applied these valuation techniques as of December 31, 2013 and believes it has obtained the most accurate information available for the types of derivative contracts it holds. The Company attempts to manage exposure to counterparty credit risk by only entering into agreements with major financial institutions, which are expected to be able to fully perform under the terms of the agreement.

The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item; the derivative expires or is sold, terminated or exercised; the derivative is no longer designated as a hedging instrument because it is unlikely that a forecasted transaction will occur; or management determines that the designation of the derivative as a hedging instrument is no longer appropriate. When hedge accounting is discontinued, the Company would carry the derivative instrument on the balance sheet at its fair value with subsequent changes in fair value included in earnings, and gains and losses that were accumulated in other comprehensive income are recognized immediately in earnings to the extent the forecasted transaction is not expected to occur, or when the underlying transaction settles.

To the extent that derivative instruments do not qualify for hedge accounting treatment, the changes in fair market value of the instruments are reported in the results of operations for the current period. As a result of the senior secured Credit Agreement entered into on April 18, 2012, the interest rate swaps no longer qualify for hedge accounting while LIBOR is below the LIBOR floor of 75 basis points under the Credit Agreement. Amounts in other comprehensive income for interest rate swaps as of April 18, 2012 have been included in earnings.

The Company enters into master netting arrangements for its derivatives to mitigate the credit risk of financial instruments. The master netting arrangements do not impact the consolidated balance sheet for December 31, 2013 or December 31, 2012, respectively.

The Company has certain derivative instruments covered by master netting arrangements whereby, in the event of a default as defined by the senior secured credit facility or termination event, the non-defaulting party has the right to offset any amounts payable against any obligation of the defaulting party under the same counterparty agreement.

The entire asset classes of the Company are pledged as collateral for both the term loan and the revolving credit facility under the Company's senior secured credit facility (see Note 15, "Debt").

Interest Rate Swaps

We enter into floating-to-fixed interest rate swap agreements periodically. As of December 31, 2013, the interest rate swap agreements had notional amounts totaling $225.

The fixed rate represents the rate at which interest is paid by the Company pursuant to the terms of its interest rate swap agreements.

As of December 31, 2013 the interest rate swaps are no longer effective and therefore the effective fixed rate is not applicable.

The purpose of entering into these swaps was to reduce the Company's exposure to variable interest rates. The interest rate swaps settle on a monthly basis when interest payments are made. These settlements occur through the maturity date. The interest rate swaps are being accounted for as cash flow hedges in accordance with FASB authoritative guidance. The fair value of the interest rate swaps was a liability (unrealized loss) of ($1.4) at December 31, 2013 and ($4.0) at December 31, 2012.

Foreign Currency Forward Contracts

We could use foreign currency hedge contracts to reduce our exposure to currency exchange rate fluctuations, which include hedging contracts to hedge U.S. dollar revenue from certain customers. The objective of these contracts would minimize the impact of currency exchange rate movements on our operating results. The hedges would be accounted for as cash flow hedges in accordance with FASB authoritative guidance. Gains and losses from cash flow hedges would be recorded to other comprehensive income until the underlying transaction for which the hedge was placed occurs and then the value in other comprehensive income is reclassified to earnings. The exception to the aforementioned treatment of realized gains/losses involves certain cash payments to Airbus, payable in British pounds sterling which were hedged, and this amount in other comprehensive income was reclassified into other assets when the underlying transaction occurred and will be amortized over the first A350 XWB contract block.

The following table summarizes the Company's fair value of outstanding derivatives at December 31, 2013 and December 31, 2012:

	At December 31, 2013 and December 31, 2012, the fair value of certain investments in debt and marketable securities are less than their historical cost. Total fair value of these investments was $1.8 and $0.8, respectively, for the periods then ended, which is approximately 51% and 22%, respectively, of the Company's held-to-maturity investment portfolio. These declines primarily resulted from decreases in market interest rates and failure of certain investments to maintain consistent credit quality ratings or meet projected earnings targets.
	Based on evaluation of available evidence, including changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary.
	Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period in which the permanent impairment is identified.

	Senior Secured Credit Facilities
	On April 18, 2012, Spirit entered into a $1.2 billion senior secured Credit Agreement (the "Credit Agreement") consisting of a $650.0 revolving credit facility and a $550.0 term loan B facility. The Credit Agreement refinanced and replaced the Second Amended and Restated Credit Agreement dated as of November 27, 2006, as amended. Proceeds of the new term loan were used to pay off outstanding amounts under the prior credit agreement. The revolving credit facility matures April 18, 2017 and bears interest, at Spirit's option, at either LIBOR, or a defined "base rate" plus an applicable margin based on Spirit's debt-to-EBITDA ratio (see table below). The term loan matures April 18, 2019 and bears interest, at Spirit's option, at LIBOR plus 3.00% with a LIBOR floor of 0.75% or base rate plus 2.00%, subject to a step down to LIBOR plus 2.75% or base rate plus 1.75%, as applicable, in the event Spirit's secured debt-to-EBITDA ratio is below 1:1 at any time after 2012. Substantially all of Spirit's assets, including inventory and property, plant and equipment, were pledged as collateral for both the term loan and the revolving credit facility. As of December 31, 2013, the outstanding balance of the term loan was $540.4. As of December 31, 2012, the outstanding balance of the term loan was $545.9. As of December 31, 2013, the carrying amount of the term loan was $538.2. The amount outstanding under the revolving credit facility was zero as of December 31, 2013 and December 31, 2012. The Company recorded a charge of $9.5 in 2012 for unamortized deferred financing fees as a result of extinguishment of the debt under the prior credit agreement.
	In addition to paying interest on outstanding principal under the Credit Agreement, Spirit is required to pay an unused line fee on the unused portion of the commitments under the revolving credit facility based on Spirit's debt-to-EBITDA ratio (see table below). Spirit is required to pay letter of credit fees equal to the applicable margin for LIBOR rate revolving credit borrowings with respect to letters of credit issued under the revolving credit facility (see table below). Spirit is also required to pay to the issuing banks that issue any letters of credit, letter of credit fronting fees in respect of letters of credit at a rate equal to twenty basis points per year, and to the administrative agent thereunder customary administrative fees.
	Pricing Tier	Debt-to-EBITDA		Commitment			Letter of		Eurodollar		Base Rate

	4	<1.75:1		0.25	%		1.75	%	1.75	%	0.75	%
	The Credit Agreement contains customary affirmative and negative covenants, including restrictions on indebtedness, liens, type of business, acquisitions, investments, sales or transfers of assets, payments of dividends, transactions with affiliates, change in control and other matters customarily restricted in such agreements. The Credit Agreement also contained the following financial covenants (as defined in the Credit Agreement):
	Senior Secured Leverage Ratio		Shall not exceed 2.75:1.0
	Interest Coverage Ratio		Shall not be less than 4.0:1.0
	Total Leverage Ratio		Shall not exceed 4.0:1.0
	To address the forward loss charges that the Company recognized in the third quarter of 2012, the Company amended the Credit Agreement effective October 26, 2012. The amendment resulted in a temporary revision of the quarterly financial covenant ratios and increased the amount of time the Company has to apply the proceeds from the insurance settlement in connection with the severe weather event against expenses resulting from the event from 12 months to 24 months before the proceeds may be considered eligible for prepayment against the senior secured credit facility.
	Additionally, to address the forward loss charges that the Company recognized in the second quarter of 2013, the Company amended the Credit Agreement effective August 2, 2013. The amendment suspended the existing financial covenant ratios until December 31, 2014. The amendment requires Spirit to meet certain minimum liquidity and borrowing base requirements while the existing financial covenant ratios are suspended. Among other things, the amendment provides for the following key changes during the suspension period:
	•	The applicable margin for the revolving credit facility component of the senior secured Credit Agreement shall be the applicable percentage per annum set forth in Pricing Tier 1 (see table above), plus one-half of one percent (0.5)%.
	•	The applicable margin for the term loan B credit facility component of the senior secured Credit Agreement shall be 3.00% per annum for Eurodollar Rate Loans and 2.00% per annum for Base Rate Loans.
	•	The Total Secured Outstandings (as defined in the Credit Agreement) shall not exceed the Aggregate Borrowing Base Amount (as defined in the Credit Agreement) Spirit is required to maintain and liquidity is not to be less than $500.0.
	In addition, pursuant to the amendment the mandatory application of proceeds from the potential sale of the Oklahoma sites to repay the borrowings under the senior secured credit agreement is reduced from 100% to 50%. The Company expects to be in compliance with all required covenants through December 31, 2014.
	On February 6, 2014, Moody's Investors Service placed the credit ratings of Spirit AeroSystems, Inc. under review for possible downgrade. A downgrade of our credit ratings could trigger a prepayment based on the excess cash flow prepayment provision under our term loan depending on our total leverage ratio.
	Senior Notes
	On November 18, 2010, we issued $300.0 aggregate of 6.75% Senior Notes due December 15, 2020 (the "2020 Notes"), with interest payable, in cash in arrears, on June 15 and December 15 of each year, beginning June 15, 2011. The 2020 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Company and Spirit's existing and future domestic subsidiaries that guarantee Spirit's obligations under Spirit's senior secured credit facility. The carrying value of the 2020 Notes was $300.0 as of December 31, 2013.
	On September 30, 2009, we issued $300.0 of 7.50% Senior Notes due October 1, 2017 (the "2017 Notes"), with interest payable, in cash in arrears, on April 1 and October 1 of each year, beginning April 1, 2010. The 2017 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Company and Spirit's existing and future domestic subsidiaries that guarantee Spirit's obligations under Spirit's senior secured credit facility. The carrying value of the 2017 Notes was $296.4 as of December 31, 2013.
	As of December 31, 2013, we were and expect to remain in full compliance with all covenants contained in the indentures governing the 2020 Notes and the 2017 Notes through December 31, 2014.
	Malaysian Facility Agreement
	On June 2, 2008, the Company's wholly-owned subsidiary, Spirit AeroSystems Malaysia SDN BHD entered into a Facility Agreement for a term loan facility for Ringgit Malaysia ("RM") 69.2 (approximately USD $20.0 equivalent) (the "Malaysia Facility"), with the Malaysian Export-Import Bank. The Malaysia Facility requires quarterly principal repayments of RM3.3 (approximately USD $1.0) from September 2011 through May 2017 and quarterly interest payments payable at a fixed interest rate of 3.50% per annum. The Malaysia Facility loan balance as of December 31, 2013 was $10.0.
	French Factory Capital Lease Agreement
	On July 17, 2009, the Company's indirect wholly-owned subsidiary, Spirit AeroSystems France SARL entered into a capital lease agreement for €9.0 (approximately USD $13.1 equivalent) with a subsidiary of BNP Paribas Bank to be used towards the construction of our aerospace-related component assembly plant in Saint-Nazaire, France. Lease payments are variable, subject to the three-month Euribor rate plus 2.20%. Lease payments are due quarterly through April 2025. As of December 31, 2013 and December 31, 2012, the Saint-Nazaire capital lease balance was $10.7 and $11.0, respectively.
	Nashville Design Center Capital Lease Agreement
	On September 21, 2012, the Company entered into a capital lease agreement for $2.6 for a portion of an office building in Nashville, Tennessee to be used for design of aerospace components. Lease payments are due monthly, and are subject to yearly rate increases until the end of the lease term of 124 months. As of December 31, 2013 and December 31, 2012, the Nashville Design Center capital lease balance was $2.5 and $2.6, respectively.

	Pension and Other Post-Retirement Benefits
	Multi-employer Pension Plan
	In connection with the collective bargaining agreement signed with the International Association of Machinists and Aerospace Workers (IAM), the Company contributes to a multi-employer defined benefit pension plan (IAM National Pension Fund). The level of contribution, as specified in the bargaining agreement was $1.35 per hour of employee service for a maximum of 80 hours per bi-weekly pay period through June 30, 2010. Effective July 1, 2010 the contribution per the collective bargaining agreement is $1.50 per hour of employee service for a maximum of 80 hours per bi-weekly pay period. The IAM bargaining agreement provides for a $0.05 increase per hour in the contribution rate beginning on July 1, 2011, with an additional $0.05 increase effective July 1 of each year through 2019.
	The collective bargaining agreement with the UAW requires the Company to contribute a specified amount per hour of service to a multi-employer defined benefit pension plan (IAM National Pension Fund). The specified amount was $1.30 in 2010. Per the negotiated UAW collective bargaining agreement, the pension contributions will be as follows:
	Effective 1/1/2011 — $1.45
	Effective 1/1/2012 — $1.50
	Effective 1/1/2014 — $1.55
	Effective 1/1/2016 — $1.60
	Effective 1/1/2018 — $1.65
	Effective 1/1/2019 — $1.70
	Effective 1/1/2020 — $1.75
	The risk of this multi-employer plan is different from single-employer plans in the following aspects:
	1	Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers.
	2	If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
	3	If the Company chooses to stop participating in the multi-employer plan, the Company may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
	The following table summarizes the multi-employer plan to which the Company contributes:

	Defined Contribution Plans
	The Company contributes to a defined contribution plan available to all U.S. employees, excluding IAM and UAW represented employees. Under the plan, the Company makes a matching contribution of 75% of the employee contribution to a maximum 8% of eligible individual employee compensation. In addition, non-matching contributions based on an employee's age and years of service are paid at the end of each calendar year for certain employee groups.
	The Company recorded $39.1, $39.5 and $38.4 in contributions to these plans for the twelve months ended December 31, 2013, December 31, 2012 and December 31, 2011, respectively.
	On April 1, 2006, as part of the acquisition of BAE Aerostructures, the Company established a defined contribution pension plan for those employees who are hired after the date of acquisition. Under the plan, the Company contributes 8% of basic salary while participating employees are required to contribute 4% of basic salary. The Company recorded $1.8 in contributions to this plan for the period ended December 31, 2013, $0.8 in contributions for the period ended December 31, 2012 and $0.7 in contributions for the period ended December 31, 2011.
	Defined Benefit Pension Plans
	Effective June 17, 2005, pension assets and liabilities were spun-off from three Boeing qualified plans into four qualified Spirit AeroSystems plans for each Spirit employee who did not retire from Boeing by August 1, 2005. Effective December 31, 2005, all four qualified plans were merged together. In addition, Spirit has one nonqualified plan providing supplemental benefitsto executives (SERP) who transferred from a Boeing nonqualified plan to a Spirit AeroSystems plan and elected to keep their benefits in this plan. Both plans are frozen as of the date of the Boeing Acquisition (i.e., no future service benefits are being earned in these plans). We intend to fund our qualified pension plan through a trust. Pension assets are placed in trust solely for the benefit of the pension plans' participants and are structured to maintain liquidity that is sufficient to pay benefit obligations.
	On April 1, 2006, as part of the acquisition of BAE Aerostructures, the Company established a defined benefit pension plan for those employees that had pension benefits remaining in BAE Systems' pension plan.  In accordance with U.K. legislation, the plan and its assets are managed by an independent trustee company.  The investment strategy adopted by this trustee is documented in a Statement of Investment Principles in line with U.K. legislation. The principles for the investment strategy are to maximize the long-term rate of return on plan assets within an acceptable level of risk while maintaining adequate funding levels. The trustee has invested the plan assets in pooled arrangements with authorized investment companies which were selected to be consistent with the plan's overall investment principles and strategy. The specified target asset allocation is 55% equities, 5% real estate, 20% corporate bonds and 20% government bonds.
	Effective December 31, 2013, the U.K. pension plan was closed and benefits were frozen and thereafter subject only to statutory pension revaluation, resulting in a net curtailment gain of $13.1. This gain was due to the loss of salary linkage for employed members of the plan, less the cost of other benefit changes made as part of the plan closure.
	Other Post-Retirement Benefit Plans
	We also have post-retirement health care coverage for eligible U.S. retirees and qualifying dependents prior to age 65. Eligibility for employer-provided benefits is limited to those employees who were employed at the date of acquisition (Spirit) and retire on or after attainment of age 62 and 10 years  of service. Employees who do not satisfy these eligibility requirements can retire with post-retirement medical benefits at age 55 and 10 years  of service, but they must pay the full cost of medical benefits provided.
	Obligations and Funded Status
	The following tables reconcile the funded status of both pension and post-retirement medical benefits to the balance on the consolidated balance sheets for the fiscal years 2013 and 2012. Benefit obligation balances presented in the tables reflect the projected benefit obligation (PBO) and accumulated benefit obligation (ABO) for our pension plans, and accumulated post-retirement benefit obligations (APBO) for our post-retirement medical plan. We use an end of fiscal year measurement date of December 31 for our U.S. pension and post-retirement medical plans as required by FASB authoritative guidance.

The estimated net (gain) loss that will be amortized from other comprehensive income into net periodic benefit cost over the next fiscal year for the U.K. plan is zero.
Assumptions
The Company sets the discount rate assumption annually for each of its retirement-related benefit plans as of the measurement date, based on a review of projected cash flow and a long-term high-quality corporate bond yield curve. The discount rate determined on each measurement date is used to calculate the benefit obligation as of that date, and is also used to calculate the net periodic benefit (income)/cost for the upcoming plan year.
The pension expected return on assets assumption is derived from the long-term expected returns based on the investment allocation by class specified in the Company's investment policy. The expected return on plan assets determined on each measurement date is used to calculate the net periodic benefit (income)/cost of the upcoming plan year.
Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. To determine the health care cost trend rates the Company considers national health trends and adjusts for its specific plan design and locations.
A one-percentage point increase in the initial through ultimate assumed health care trend rates would have increased the accumulated post-retirement benefit obligation by $5.7 at December 31, 2013 and the aggregate service and interest cost components of non-pension post-retirement benefit expense for 2013 by $0.4. A one-percentage point decrease would have decreased the obligation by $5.2 and the aggregate service and interest cost components of non-pension post-retirement benefit expense for 2013 by $0.4.
U.S. Plans
The Company's investment objective is to achieve long-term growth of capital, with exposure to risk set at an appropriate level. This objective shall be accomplished through the utilization of a diversified asset mix consisting of equities (domestic and international) and taxable fixed income securities. The allowable asset allocation range is:
Equities	20 - 50%
Fixed income	50 - 80%
Real estate	0 -   7%
Investment guidelines include that no security, except issues of the U.S. Government, shall comprise more than 5% of total Plan assets and further, no individual portfolio shall hold more than 7% of its assets in the securities of any single entity, except issues of the U.S. Government. The following derivative transactions are prohibited — leverage, unrelated speculation and "exotic" collateralized mortgage obligations or CMOs. Investments in hedge funds, private placements, oil and gas and venture capital must be specifically approved by the Company in advance of their purchase.
The Company's plans have asset allocations for the U.S., as of December 31, 2013 and December 31, 2012, as follows:
	2013			2012
Asset Category — U.S.
Equity securities — U.S.	29	%		29	%
Equity securities — International	4	%		4	%
Debt securities	65	%		65	%
Real estate	2	%		2	%
Total	100	%		100	%
U.K. Plans
The Trustee's investment objective is to ensure that they can meet their obligation to the beneficiaries of the Plan. An additional objective is to achieve a return on the total Plan, which is compatible with the level of risk considered appropriate. The overall benchmark allocation of the Plan's assets is:
Equity securities	55	%
Debt securities	40	%
Property	5	%
The Company's plans have asset allocations for the U.K., as of December 31, 2013 and December 31, 2012, as follows:
	2013			2012
Asset Category — U.K.
Equity securities	54	%		56	%
Debt securities	37	%		39	%
Other	9	%		5	%
Total	100	%		100	%
Projected contributions and benefit payments
Required pension contributions under Employee Retirement Income Security Act (ERISA) regulations are expected to be zero in 2014 and discretionary contributions are not expected in 2014. SERP and post-retirement medical plan contributions in 2014 are not expected to exceed $2.9. Expected contributions to the U.K. plan for 2014 are $0.7.
We monitor our defined benefit pension plan asset investments on a quarterly basis and we believe that we are not exposed to any significant credit risk in these investments.
The total benefits expected to be paid over the next ten years from the plans' assets or the assets of the Company, by country, are as follows:

Fair Value Measurements
The pension plan assets are valued at fair value. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy.
Temporary Cash Investments — These investments consist of U.S. dollars and foreign currencies held in master trust accounts. Foreign currencies held are reported in terms of U.S. dollars based on currency exchange rates readily available in active markets. These temporary cash investments are classified as level 1 investments.
Collective Investment Trusts — These investments are public investment vehicles valued using middle market prices and performance of the fund. The trust allocates notional units to the policy holder based on the underlying notional unit buy (offer) price using the middle market price plus transaction costs. These investments are classified within level 2 of the valuation hierarchy. In addition, the collective investment trust includes a real estate fund which is classified within level 3 of the valuation hierarchy.
Commingled Equity and Bond Funds — These investments are valued at the closing price reported by the Plan Trustee. These investments are not being traded in an active market, but are backed by various investment securities managed by the Bank of New York. Fair value is being calculated using unobservable inputs that rely on the Bank of New York's own assumptions and are therefore classified within level 2 of the valuation hierarchy, although these assumptions are based on underlying investments which are traded on an active market.
As of December 31, 2013 and December 31, 2012, the pension plan assets measured at fair value on a recurring basis were as follows:

Stock Compensation	'
	Stock Compensation
	Holdings has established various stock compensation plans which include restricted share grants and stock purchase plans. Compensation values are based on the value of Holdings' common stock at the grant date. The common stock value is added to equity and charged to period expense or included in inventory and cost of sales.
	For the fiscal period ended December 31, 2013, Holdings has recognized a net total of $19.6 of stock compensation expense. The entire $19.6 of net stock compensation expense recorded in 2013 was charged directly to selling, general and administrative expense accordance with FASB authoritative guidance, which included $0.5 of accelerated vesting expense for participants meeting the conditions for "qualifying retirement" under our Short-Term Incentive Plan. Holdings recognized a total of $15.3 and $11.2 of stock compensation expense for the periods ended December 31, 2012 and December 31, 2011, respectively. The total income tax benefit recognized in the income statement for share based compensation arrangements was $7.1, $5.6, and $4.1 for 2013, 2012, and 2011, respectively.
	Executive Incentive Plan
	The Company's Executive Incentive Plan, or EIP, is designed to provide participants with the opportunity to acquire an equity interest in the Company through direct purchase of the Company's class B common stock shares at prices established by the Board of Directors or through grants of class B restricted common stock shares with performance based vesting. The Company has the sole authority to designate either stock purchases or grants of restricted shares. The total number of shares authorized under the EIP is 12,000,000 and the grant terminates at the end of ten years.
	The Company has issued restricted shares as part of the Company's EIP. The restricted shares have been granted in groups of four shares. Participants do not have the unrestricted rights of stockholders until those shares vest. The shares may vest upon a liquidity event, with the number of shares vested based upon a participant's number of years of service to the Company, the portion of the investment by Onex and its affiliates liquidated through the date of the liquidity event and the return on invested capital by Onex and its affiliates through the date of the liquidity event. If a specific type of liquidity event has not occurred by the 10th year, shares may vest based on a valuation of the Company. The Company's initial public offering in November 2006 (the "IPO") and secondary offerings in May 2007 and April 2011 were considered liquidity events under the EIP. The Company records expenses equal to the fair value of the award over a five-year vesting period. The fair value of the award is based on the value of each share at the time of the grant multiplied by the probability of the share vesting based on historical performance of Onex's controlled investments.
	The Company did not recognize any expense under the EIP for the year ended December 31, 2013. The Company expensed zero and a net total of less than $0.1 for the periods ended December 31, 2012 and December 31, 2011, respectively. The weighted average remaining period for the vesting of these shares is 1.5 years. The intrinsic value of the unvested shares based on the value of the Company's stock at December 31, 2013 was $29.6, based on the value of the Company's stock and the number of unvested shares.
	The following table summarizes the activity of restricted shares under the EIP for the periods ended December 31, 2013, December 31, 2012 and December 31, 2011:

	Board of Directors Stock Awards
	The Company's Director Stock Plan provides non-employee directors the opportunity to receive grants of restricted shares of class A common stock, or Restricted Stock Units (RSUs) or a combination of both common stock and RSUs. The class A common stock grants and RSU grants vest one year from the grant date. The RSU grants are payable upon the director's separation from service. The Board of Directors or its authorized committee may make discretionary grants of shares or RSUs from time to time. The maximum aggregate number of shares that may be granted to participants is 3,000,000 shares. In April 2008, the Director Stock Plan was amended such that all issuances of stock pursuant to the plan after that date would be grants of class A common stock or RSUs. All shares granted prior to April 2008 were class B common stock.
	For each non-employee director of the Company, at least one-half of their annual director compensation is required to be paid in the form of a grant of class A common stock and/or RSUs, as elected by each director. In addition, each director may elect to have all or any portion of the remainder of their annual director compensation paid in cash or in the form of a grant of class A stock and/or RSUs. If participants cease to serve as directors within a year of the grant, the restricted shares and/or RSUs are forfeited. In May and December of 2013, the Board of Directors authorized a grant of 34,747 and 4,321 shares of restricted class A common stock, respectively, valued at $0.9 based on the share price of the Company's common stock at the grant dates. The Company expensed a net amount of $0.7 for the Board of Directors shares for the period ended December 31, 2013. The Company expensed $0.7 during each of the periods ended December 31, 2012 and December 31, 2011. The Company's unamortized stock compensation related to these restricted shares is $0.4 which will be recognized over a weighted average remaining period of 11 months. The intrinsic value of the unvested shares based on the value of the Company's stock at December 31, 2013 was $1.3, based on the value of the Company's stock and the number of unvested shares.
	The following table summarizes stock and RSU grants to members of the Company's Board of Directors for the periods ended December 31, 2013, December 31, 2012 and December 31, 2011:

	Short-Term Incentive Plan
	The Second Amended and Restated Short-Term Incentive Plan ("STIP") enables eligible employees to receive incentive benefits in the form of restricted stock in the Company, cash, or both, as determined by the Board of Directors or its authorized committee. The stock portion vests one year from the date of grant. Restricted shares are forfeited if the employee's employment terminates prior to vesting. In August 2011, the STIP was amended such that all unvested stock will vest in the event of a qualifying retirement or change in control.
	In February 2013, 86,063 shares of Class A common stock with a value of $1.4 were granted under the Company's STIP for 2012 performance and will vest on the one-year anniversary of the grant date. The Company expensed $1.3 for shares granted under the STIP for the period ended December 31, 2013. The Company expensed $2.9 and $3.9 for the shares for the periods ended December 31, 2012 and December 31, 2011, respectively. The Company's unamortized stock compensation related to the unvested shares is $0.1, which will be recognized over a weighted average remaining period of 2 months. The intrinsic value of the unvested shares at December 31, 2013 was $2.1 based on the value of the Company's stock and the number of unvested shares.
	The following table summarizes the activity of the restricted shares under the STIP for the twelve months ended December 31, 2013, December 31, 2012 and December 31, 2011:

Long-Term Incentive Plan
The Fourth Amended and Restated Long-Term Incentive Plan ("LTIP") is designed to encourage retention of key employees.
For shares granted in 2007, one-half of the granted restricted shares of class B common stock vested on the second anniversary of the grant date in February 2009, and the other one-half vested on the fourth anniversary of the grant date in 2011. Restricted shares are forfeited if the participant's employment terminates prior to vesting. In the first quarter of 2007, 67,391 shares valued at $2.0 were granted. The Company expensed zero, zero and less than $0.1 net of forfeitures for each of the periods ended December 31, 2013, December 31, 2012 and December 31, 2011, respectively.
In February and April 2013, as part of the Company's 2012 Long-Term Incentive Plan, 9,460 and 33,784 shares of class A common stock with an aggregate grant date fair value of $0.8 were granted by the Board of Directors, and such shares will vest annually in three equal installments beginning on the two-year anniversary of the grant date.

	Net non-current deferred tax asset	$	(42.2	)	$	184.8
	Total deferred tax asset	$	(15.8	)	$	238.6
	A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, Management assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified.  As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.
	Based on these criteria and the relative weighting of both the positive and negative evidence available, and in particular the activity surrounding the Company’s prior earnings history including the forward losses previously recognized in the U.S., management determined that it was necessary to establish a valuation allowance against nearly all of its net U.S. deferred tax assets at December 31, 2013. This determination was made as the Company entered into a cumulative loss position in recent years once results from the year ended December 31, 2013 were included, the threshold after which there is a presumption that a company should no longer rely solely on projected future income in determining whether the deferred tax asset is more likely than not to be realized. As of December 31, 2013, the total net U.S. deferred tax asset was $399.6. The net U.S. deferred tax asset after recording valuation allowances is $3.7. Valuation allowances recorded against the consolidated net U.S. deferred tax asset in the current year were $381.0. Additionally, the Company maintains a $14.9 valuation allowance against separate company state income tax credits and previously recorded other U.S. issues and $0.6 for other foreign issues which is an increase of $5.1 from the prior year. The Company will continue to monitor its deferred tax position and may adjust the valuation allowance, if necessary, for utilization of the underlying deferred tax assets through current taxable income or as available evidence changes.
	Certain amounts in 2012 and 2011 tax footnote have been reclassified to conform to the 2013 presentation.
	The increase from 2012 to 2013 in the long-term contracts deferred tax asset is primarily due to forward losses recognized during 2013 that are not currently deductible for tax.
	The decrease from 2012 to 2013 in the severe weather event deferred tax liability represents the identification and capitalization of qualified replacement property for book purposes with a corresponding increase to the deferred tax liability for depreciation and amortization.
We have recognized cumulative book income for our international operations, but have incurred cumulative taxable losses in the United Kingdom. The resulting net operating loss carryforward is primarily due to the manner in which the United Kingdom treats long-term contract income accounting and capital allowances.
As required under FASB authoritative guidance, $0.0 and $1.1 was recorded to Additional Paid in Capital, representing the tax effect associated with the net excess tax pool created during the periods ended December 31, 2013 and December 31, 2012, respectively.
As of December 31, 2013, the Company has not provided U.S. tax on its cumulative undistributed earnings of foreign subsidiaries of approximately $129.0 because it is the Company’s intention to reinvest these earnings indefinitely. The calculation of the unrecognized deferred tax liability related to these earnings is complex and the calculation is not practicable. If earnings were distributed, the Company would be subject to U.S. taxes and withholding taxes payable to foreign governments. Based on the facts and circumstances at that time, the Company would determine whether a credit for foreign taxes paid would be available to reduce or offset the U.S. tax liability.
The beginning and ending unrecognized tax benefits reconciliation is as follows:
	2013			2012				2011
Beginning balance	$	16.9		$	15.5			$	15.2
Gross increases related to current period tax positions	3.8			4.2				6.1
Gross increases related to prior period tax positions	0.4			1.8				33.5
Gross decreases related to prior period tax positions	(2.7		)	(3.8		)		(9.3		)
Statute of limitations' expiration	—			(0.8		)		(0.8		)

Ending balance	$	18.4		$	16.9			$	15.5
Included in the December 31, 2013 balance was $16.5 in tax affected unrecognized tax benefits which, if ultimately recognized, will reduce the Company's effective tax rate. The Internal Revenue Service's examination of the Company's 2012 U.S. Federal income tax return is complete. The Company will continue to participate in the Compliance Assurance Process ("CAP") program for our 2013 tax year. Additionally, we have been selected for the Compliance Maintenance phase of the CAP program for the 2014 tax year. The CAP program's objective is to resolve issues in a timely, contemporaneous manner and eliminate the need for a lengthy post-filing examination. HM Revenue & Customs is currently examining our 2009, 2010 and 2011 U.K. income tax returns. The Directorate General of Public Finance is currently examining our 2011 and 2012 France income tax returns. While a change could result from the ongoing examinations, the Company expects no material change in its recorded unrecognized tax benefit liability in the next 12 months, other than the potential $12.2 reduction for Malaysia mentioned below.
Our U.S. federal income tax return for the 2010 tax year is subject to examination. We are also subject to examination in various states and foreign jurisdictions for the 2009-2013 tax years.
We report interest and penalties, if any, related to unrecognized tax benefits in the income tax provision. As of December 31, 2013 and December 31, 2012, accrued interest on our unrecognized tax benefit liability included in the consolidated balance sheets was $0.1 and $0.7, respectively. The impact of interest on our unrecognized tax benefit liability during 2013 and 2012 was $(0.6) and $0.6, respectively.
We operate under a tax holiday in Malaysia effective through September 2024. During the current year, management continues to maintain a reserve for potential uncertainty in meeting the tax holiday's conditional employment and investment thresholds. While management believes we have met the required employment and investment thresholds, we continue to work through the process of validating the results with the respective Malaysian governmental authorities. If we can successfully demonstrate that the objectives have been achieved and the respective Malaysian authorities certify the results, we expect a $12.2 reduction in our unrecognized tax benefit liability.
At December 31, 2013, we had $2.6 in United Kingdom net operating loss carryforwards that do not expire and $18.1 in North Carolina net operating loss carryforwards that expire in 2025.
At December 31, 2013, we had $1.1 of U.S. Foreign Tax Credit carryforwards, a portion of which will expire beginning in 2018.
On January 2, 2013, the President signed legislation retroactively extending the U.S. Research Tax Credit for two years, from January 1, 2012 through December 31, 2013. Our income tax expense for 2013 reflects the entire benefit of the Research Tax Credit attributable to 2012, which was $5.8. We also recorded the benefit of the 2013 Research Tax Credit of $5.1 in our 2013 tax expense.
Included in the deferred tax assets at December 31, 2013 are $36.6 in Kansas High Performance Incentive Program ("HPIP") Credit, $7.3 in Kansas Research & Development ("R&D") Credit, and $2.7 in Kansas Business and Jobs Development Credit, totaling $46.6 in Kansas state income tax credit carryforwards, net of federal benefit. The HPIP Credit provides a 10% investment tax credit for qualified business facilities located in Kansas for which $5.9 expires in 2024, $0.6 expires in 2025, $3.5 expires in 2026, $5.0 expires in 2027, $9.7 expires in 2028 and the remainder expires in 2029. The R&D Credit provides a credit for qualified research and development expenditures conducted within Kansas. This credit can be carried forward indefinitely. The Business and Jobs Development Credit provides a tax credit for increased employment in Kansas. This credit can be carried forward indefinitely. As previously discussed, management determined that it was necessary to establish a valuation allowance against nearly all of its net U.S. deferred tax assets at December 31, 2013. This determination was made as the Company entered into a cumulative loss position in recent years once results from the year ended December 31, 2013 were included, the threshold after which there is a presumption that the Company should no longer rely solely on projected future income in determining whether the deferred tax asset is more likely than not to be realized. As a result, a full valuation allowance against all Kansas credits included as deferred tax assets is reflected within the total valuation allowance amount.
Included in the deferred tax assets at December 31, 2013 are $6.8 in North Carolina Investing in Business Property Credit, $3.9 in North Carolina Investment in Real Property Credit, and $3.9 in North Carolina Creating Jobs Credit, totaling $14.6 in North Carolina state income tax credit carryforwards, net of federal benefit. The Investing in Business Property Credit provides a 7% investment tax credit for property located in a North Carolina development area and the Investment in Real Property Credit provides a 30% investment tax credit for real property located in a North Carolina development area. The Creating Jobs Credit provides a tax credit for increased employment in North Carolina. These North Carolina state income tax credits can be carried forward 20 years. It is management's opinion that $1.6 of these North Carolina state income tax credits will be utilized before they expire and a $12.9 valuation allowance was recorded, net of federal benefit.

	Equity
	Earnings per Share Calculation
	Basic net income per share is computed using the weighted-average number of outstanding shares of common stock during the measurement period. Diluted net income per share is computed using the weighted-average number of outstanding shares of common stock and, when dilutive, potential outstanding shares of common stock during the measurement period.
	Subject to preferences that may apply to shares of preferred stock outstanding at the time, holders of the Company's outstanding common stock are entitled to any dividend declared by the Board of Directors out of funds legally available for this purpose. No dividend may be declared on the Class A or Class B common stock unless at the same time an equal dividend is paid on every share of Class A and Class B common stock. Dividends paid in shares of the Company's common stock must be paid, with respect to a particular class of common stock, in shares of that class. The Company does not intend to pay cash dividends on its common stock. In addition, the terms of the Company's current financing agreements preclude it from paying any cash dividends on its common stock.
	The following table sets forth the computation of basic and diluted earnings per share:

	The balance of outstanding common shares presented in the consolidated statement of shareholders' equity was 144.8 million, 143.7 million and 142.9 million at December 31, 2013, December 31, 2012 and December 31, 2011, respectively. Included in the outstanding common shares were 3.4 million, 2.7 million and 2.6 million of issued but unvested shares at December 31, 2013, December 31, 2012 and December 31, 2011, respectively, which are excluded from the basic EPS calculation. For the twelve months ended December 31, 2013, 1.0 million shares are not included in the calculation of diluted earnings per share, as their inclusion would have been anti-dilutive. These securities could be dilutive in future periods.

	On May 3, 2012, Hawker Beechcraft, Inc. (“Hawker”) filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code and emerged from bankruptcy on February 19, 2013 as Beechcraft Corporation. The Company’s Prestwick facility provided wing components for the Hawker 800 Series manufactured by Hawker. For the the twelve months ended December 31, 2013, December 31, 2012 and December 31, 2011 sales to Hawker were zero, $1.2 and $10.2, respectively. Receivables due from Hawker were $3.5 as of December 31, 2012, net of a $0.3 receivable write-off. The receivable was reserved against in 2012. The Company’s $3.5 receivable balance from Hawker was written off during 2013.
	The Company paid $0.4, $0.3 and $0.2 to a subsidiary of Onex for services rendered for each of the twelve month periods ended December 31, 2013, December 31, 2012 and December 31, 2011, respectively. Management believes the amounts charged were reasonable in relation to the services provided.

	Litigation
	From time to time we are subject to, and are presently involved in, litigation or other legal proceedings arising in the ordinary course of business. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available, it is the opinion of the Company that none of these items, when finally resolved, will have a material adverse effect on the Company’s long-term financial position or liquidity. Consistent with the requirements of authoritative guidance on accounting for contingencies, we had an accrual of less than $1.0 and zero at December 31, 2013 and December 31, 2012, respectively. However, an unexpected adverse resolution of one or more of these items could have a material adverse effect on the results of operations and cash flows in a particular quarter or fiscal year.
	From time to time, in the ordinary course of business and like others in the industry, we receive requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. We review such requests and notices and take appropriate action. We have been subject to certain requests for information and investigations in the past and could be subject to such requests for information and investigations in the future. Additionally, we are subject to federal and state requirements for protection of the environment, including those for disposal of hazardous waste and remediation of contaminated sites. As a result, we are required to participate in certain government investigations regarding environmental remediation actions.
	In December 2005, a federal grand jury sitting in Topeka, Kansas issued subpoenas regarding the vapor degreasing equipment at our Wichita, Kansas facility. The government’s investigation appeared to focus on whether the degreasers were operating within permit parameters and whether chemical wastes from the degreasers were disposed of properly. The subpoenas covered a time period both before and after our purchase of the Wichita, Kansas facility. Subpoenas were issued to Boeing, Spirit and individuals who were employed by Boeing prior to the Boeing Acquisition, but are now employed by us. We responded to the subpoena and provided additional information to the government as requested. On March 25, 2008, the U.S. Attorney’s Office informed the Company that it was closing its criminal file on the investigation. We understand that a civil investigation into this matter may be ongoing but the Company has not been contacted about this matter since the closing of the criminal investigation. Management believes the resolution of this matter will not materially affect the Company’s financial position, results of operations or liquidity.
	On February 16, 2007, an action entitled Harkness et al. v. The Boeing Company et al. was filed in the U.S. District Court for the District of Kansas. The defendants were served in early July 2007. The defendants included Spirit AeroSystems Holdings, Inc., Spirit AeroSystems, Inc., the Spirit AeroSystems Holdings Inc. Retirement Plan for the International Brotherhood of Electrical Workers (IBEW), Wichita Engineering Unit (SPEEA WEU) and Wichita Technical and Professional Unit (SPEEA WTPU) Employees, and the Spirit AeroSystems Retirement Plan for International Association of Machinists and Aerospace Workers (IAM) Employees, along with Boeing and Boeing retirement and health plan entities. The named plaintiffs are twelve former Boeing employees, eight of whom were or are employees of Spirit. The plaintiffs assert several claims under the Employee Retirement Income Security Act and general contract law and brought the case as a class action on behalf of similarly situated individuals. The putative class consists of approximately 2,500 current or former employees of Spirit. The parties agreed to class certification. The sub-class members who asserted claims against the Spirit entities are those individuals who, as of June 2005, were employed by Boeing in Wichita, Kansas, were participants in the Boeing pension plan, had at least 10 years of vesting service in the Boeing plan, were in jobs represented by a union, were between the ages of 49 and 55, and who went to work for Spirit on or about June 17, 2005. Although there were many claims in the suit, the plaintiffs’ claims against the Spirit entities, asserted under various theories, were (1) that the Spirit plans wrongfully failed to determine that certain plaintiffs are entitled to early retirement “bridging rights” to pension and retiree medical benefits that were allegedly triggered by their separation from employment by Boeing and (2) that the plaintiffs’ pension benefits were unlawfully transferred from Boeing to Spirit in that their claimed early retirement “bridging rights” are not being afforded these individuals as a result of their separation from Boeing, thereby decreasing their benefits. The plaintiffs initially sought a declaration that they were entitled to the early retirement pension benefits and retiree medical benefits, an injunction ordering that the defendants provide the benefits, damages pursuant to breach of contract claims and attorney fees. On June 20, 2013, the district court entered an order dismissing all claims against the Spirit entities with prejudice. Plaintiffs’ claims against Boeing entities remain pending in the litigation. Boeing has notified Spirit that it believes it is entitled to indemnification from Spirit for any “indemnifiable damages” it may incur in the Harkness litigation, under the terms of the asset purchase agreement from the Boeing Acquisition between Boeing and Spirit. Spirit disputes Boeing’s position on indemnity. Management believes the resolution of this matter will not materially affect the Company’s financial position, results of operations or liquidity.
	On July 21, 2005, the International Union, Automobile, Aerospace and Agricultural Implement Workers of America (“UAW”) filed a grievance against Boeing on behalf of certain former Boeing employees in Tulsa and McAlester, Oklahoma, regarding issues that parallel those asserted in Harkness et al. v. The Boeing Company et al. Boeing denied the grievance, and the UAW subsequently filed suit to compel arbitration, which the parties eventually agreed to pursue. The arbitration was conducted in January 2008. In July 2008, the arbitrator issued an opinion and award in favor of the UAW. The arbitrator directed Boeing to reinstate the seniority of the employees and “afford them the benefits appurtenant thereto.” On March 5, 2009, the arbitrator entered an Opinion and Supplemental Award that directed Boeing to award certain benefits to UAW members upon whose behalf the grievance was brought, notwithstanding the prior denial of such benefits by the Boeing Plan Administrator. On April 10, 2009, Boeing filed a Complaint in the United States District Court for the Northern District of Illinois, seeking a ruling that the arbitrator exceeded his authority in granting the Supplemental Award. On September 16, 2009, the District Court entered an order affirming the arbitrator’s Supplemental Award. Boeing appealed the District Court’s decision to the U.S. Seventh Circuit Court of Appeals, which affirmed the District Court’s decision. Boeing previously notified Spirit of its intent to seek indemnification from Spirit for any “indemnifiable damages” it may incur in the UAW matter, pursuant to the terms of the asset purchase agreement from the Boeing Acquisition. Spirit disputes Boeing’s position on indemnity. Management believes the resolution of this matter will not materially affect the Company’s financial position, results of operations or liquidity.
	On May 11, 2009, Spirit filed a lawsuit in the United States District Court for the District of Kansas against SPS Technologies LLC (“SPS”) and Precision Castparts Corp. Spirit’s claims are based on the sale by SPS of certain non-conforming nut plate fasteners to Spirit between August 2007 and August 2008. Many of the fasteners were used on assemblies that Spirit sold to a customer. In the fall of 2008, Spirit discovered the non-conformity and notified the customer of the discrepancy. Subsequently, Spirit and the customer removed and replaced nut plates on various in-process aircraft assemblies and subsequently agreed to an appropriate cost related to those efforts. Spirit’s lawsuit seeks damages, including damages related to these efforts, under various theories, including breach of contract and breach of implied warranty.
	On June 3, 2013, a putative class action lawsuit was commenced against the Company, Jeffrey L. Turner, and Philip D. Anderson in the U.S. District Court for the District of Kansas. The named plaintiff, who alleges that he is a purchaser of Holdings securities, alleges that defendants violated the federal securities laws by making material misrepresentations and omissions in the Company’s public disclosures about the circumstances underlying the Company’s accrual of $590.0 in forward loss charges in the third quarter of 2012. The lawsuit seeks certification of a class of all persons other than defendants who purchased Holdings securities between May 5, 2011 and October 24, 2012, and seeks an unspecified amount of damages on behalf of the putative class. On February 5, 2014, the Court entered an order naming two lead plaintiffs. The Company intends to vigorously defend against these allegations, and management believes the resolution of this matter will not materially affect the Company’s financial position, results of operations, or liquidity.
	In August 2013, the Company instituted a demand for arbitration against Gulfstream Aerospace Corporation.  Spirit seeks damages from Gulfstream for its incomplete payments to Spirit for the wings Spirit manufactures for the G650 airplane, as well as other damages and relief.  Gulfstream counterclaimed against Spirit in the arbitration, seeking liquidated damages for delayed deliveries of wings, as well as other damages and relief.  The parties have selected arbitrators, and currently expect the arbitration hearing will take place in the first quarter of 2015.  The Company intends to vigorously prosecute and defend the claims in arbitration. Management believes the resolution of this matter will not materially affect the Company's financial position, results of operations or liquidity.
	In October 2012, Spirit was advised by the Staff of the Securities and Exchange Commission that they are conducting an inquiry that the Company believes to be focused on the timing of forward losses recognized in the third quarter of 2012. The Company is fully cooperating with the inquiry. The Company cannot predict or determine whether any proceeding may be instituted as a result of the inquiry or the outcome of any proceeding that may be instituted.
	Commitments
	The Company leases equipment and facilities under various non-cancelable capital and operating leases. The capital leasing arrangements extend through 2025. Minimum future lease payments under these leases at December 31, 2013 are as follows:
					Capital
		Operating			Present			Interest		Total
					Value
	2014	$	20.8		$	1.1		$	0.5	$	22.4

	Minimum rentals	$	22.6		$	19.6		$	20.2
	Contingent rentals	—			—			—
	Less: Sub-lease	—			—			—
	Total	$	22.6		$	19.6		$	20.2
	Spirit's aggregate capital commitments totaled $226.0 and $264.8 at December 31, 2013 and December 31, 2012, respectively.
	The Company paid $0.9 and $1.2 in interest expense related to the capital leases for periods ending December 31, 2013 and December 31, 2012, respectively.
	Guarantees
	Contingent liabilities in the form of letters of credit, letters of guarantee and performance bonds have been provided by the Company. These letters of credit reduce the amount of borrowings available under the revolving credit facility. As of both December 31, 2013 and December 31, 2012, outstanding letters of credit were $19.9. Outstanding guarantees were $24.8 and $25.6 at December 31, 2013 and December 31, 2012, respectively.
	Indemnification
	The Company has entered into customary indemnification agreements with each of its Directors, and some of its executive employment agreements include indemnification provisions. Under those agreements, the Company agrees to indemnify each of these individuals against claims arising out of events or occurrences related to that individual's service as the Company's agent or the agent of any of its subsidiaries to the fullest extent legally permitted.
	Service and Product Warranties and Extraordinary Rework
	The Company provides service and warranty policies on its products. Liability under service and warranty policies is based upon specific claims and a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance or quality issues.
	The following is a roll forward of the service warranty and extraordinary rework balance at December 31, 2013 and December 31, 2012:
		2013			2012
	Balance, January 1	$	30.9		$	19.6
	Charges to costs and expenses	38.3			12
	Write-offs, net of recoveries	(0.6		)	(0.9		)
	Exchange rate	0.1			0.2
	Balance, December 31	$	68.7		$	30.9
	Bonds
	Spirit utilized City of Wichita issued Industrial Revenue Bonds ("IRBs") to finance self-constructed and purchased real and personal property at the Wichita site. Tax benefits associated with IRBs include provisions for a ten-year complete property tax abatement and a Kansas Department of Revenue sales tax exemption on all IRB funded purchases. Spirit and the Predecessor purchased these IRBs so they are bondholders and debtor / lessee for the property purchased with the IRB proceeds.
	Spirit recorded the property on its consolidated balance sheet in accordance with FASB authoritative guidance, along with a capital lease obligation to repay the IRB proceeds. Therefore, Spirit and the Predecessor have exercised their right to offset the amounts invested and obligations for these bonds on a consolidated basis. The assets and liabilities associated with these IRBs were $394.7 and $345.7 at December 31, 2013 and December 31, 2012, respectively.
	Spirit utilized $80.0 in Kansas Development Finance Authority ("KDFA") issued bonds to receive a rebate of payroll taxes from the Kansas Department of Revenue to KDFA bondholders. Concurrently, a Spirit subsidiary issued an intercompany note with identical principal, terms, and conditions to the KDFA bonds. In accordance with FASB authoritative guidance, the principal and interest payments on these bonds offset in the consolidated financial statements.

Segment_Information

Segment Information	12 Months Ended
	Dec. 31, 2013
Segment Reporting [Abstract]	'
Segment Information	'
	Segment Information
	The Company operates in three principal segments: Fuselage Systems, Propulsion Systems and Wing Systems. Substantially all revenues in the three principal segments are from Boeing, with the exception of Wing Systems, which includes revenues from Airbus and other customers. Approximately 94% of the Company's net revenues for the twelve months ended December 31, 2013 came from our two largest customers, Boeing and Airbus. All other activities fall within the All Other segment, principally made up of sundry sales of miscellaneous services, tooling contracts, and sales of natural gas through a tenancy-in-common with other companies that have operations in Wichita, Kansas. The Company's primary profitability measure to review a segment's operating performance is segment operating income before unallocated corporate selling, general and administrative expenses, unallocated impact of severe weather event, unallocated research and development and unallocated cost of sales. Unallocated corporate selling, general and administrative expenses include centralized functions such as accounting, treasury and human resources that are not specifically related to our operating segments and are not allocated in measuring the operating segments' profitability and performance and operating margins. Unallocated impact of severe weather event includes property repairs, clean up and recovery costs related to the April 14, 2012 tornado at the Company's Wichita facility. Unallocated research and development includes research and development efforts that benefit the Company as a whole and are not unique to a specific segment. Unallocated cost of sales includes general costs not directly attributable to segment operations, such as early retirement and other incentives. All of these unallocated items are not specifically related to our operating segments and are not allocated in measuring the operating segments' profitability and performance and operating margins.
	We are evaluating the potential realignment of our reportable segments as part of our 2014 business strategy. The reportable segment amounts and discussions reflected in this Annual Report reflect the management reporting that existed through the end of our 2013 fiscal year.
	The Company's Fuselage Systems segment includes development, production and marketing of forward, mid and rear fuselage sections and systems, primarily to aircraft OEMs (OEM refers to aircraft original equipment manufacturer), as well as related spares and maintenance, repairs and overhaul. The Fuselage Systems segment manufactures products at our facilities in Wichita, Kansas and Kinston, North Carolina. The Fuselage Systems segment also includes an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France.
	The Company's Propulsion Systems segment includes development, production and marketing of struts/pylons, nacelles (including thrust reversers) and related engine structural components primarily to aircraft or engine OEMs, as well as related spares and MRO services. The Propulsion Systems segment manufactures products at our facilities in Wichita and Chanute, Kansas.
	The Company's Wing Systems segment includes development, production and marketing of wings and wing components (including flight control surfaces) as well as other miscellaneous structural parts primarily to aircraft OEMs, as well as related spares and MRO services. These activities take place at the Company's facilities in Tulsa and McAlester, Oklahoma; Kinston, North Carolina; Prestwick, Scotland; and Subang, Malaysia.
	The Company's definition of segment operating income differs from operating income as presented in its primary financial statements and a reconciliation of the segment and consolidated results is provided in the table set forth below. Most selling, general and administrative expenses, and all interest expense or income, related financing costs and income tax amounts, are not allocated to the operating segments.
	While some working capital accounts are maintained on a segment basis, much of the Company's assets are not managed or maintained on a segment basis. Property, plant and equipment, including tooling, is used in the design and production of products for each of the segments and, therefore, is not allocated to any individual segment. In addition, cash, prepaid expenses, other assets and deferred taxes are managed and maintained on a consolidated basis and generally do not pertain to any particular segment. Raw materials and certain component parts are used in the production of aerostructures across all segments. Work-in-process inventory is identifiable by segment, but is managed and evaluated at the program level. As there is no segmentation of the Company's productive assets, depreciation expense (included in fixed manufacturing costs and selling, general and administrative expenses) and capital expenditures, no allocation of these amounts has been made solely for purposes of segment disclosure requirements.
	The following table shows segment revenues and operating income for the twelve months ended December 31, 2013, December 31, 2012 and December 31, 2011:
		Twelve Months Ended December 31, 2013			Twelve Months Ended December 31, 2012				Twelve Months Ended December 31, 2011

Developments on Our Maturing Programs	'
	Developments on Our New and Maturing Programs
	A significant portion of the Company's future revenues is expected to be derived from new and maturing programs, most notably the B787, A350 XWB, G650 and G280, on which we may be contracted to provide design and engineering services, recurring production, or both. There are several risks inherent to such new and maturing programs. In the design and engineering phase, we may incur costs in excess of our forecasts due to several factors, including cost overruns, customer-directed change orders and delays in the overall program. We may also incur higher than expected recurring production costs, which may be caused by a variety of factors, including the future impact of engineering changes (or other change orders) or our inability to secure contracts with our suppliers at projected cost levels. Our ability to recover these excess costs from the customer will depend on several factors, including our rights under our contracts for the new and maturing programs. In determining our profits and losses in accordance with the percentage-of-completion method of contract accounting, we are required to make significant assumptions regarding our future costs and revenues, as well as the estimated number of units to be manufactured under the contract and other variables. We continually review and update our assumptions based on market trends and our most recent experience. If we make material changes to our assumptions, such as a reduction in the estimated number of units to be produced under the contract (which could be caused by emerging market trends or other factors), an increase in future production costs or a change in the recoverability of increased design or production costs, we may experience negative cumulative catch-up adjustments related to revenues previously recognized. In some cases, we may recognize forward loss amounts.
Research and Development	'
	Research and Development
	Research and development includes costs incurred for experimentation, design and testing and are expensed as incurred as required under FASB authoritative guidance pertaining to accounting for research and development costs.
Joint Venture	'
	Joint Venture
	The value of the Company's 31.5% ownership interest in Taikoo Spirit AeroSystems Composite Co. Ltd. totaled $1.4 at December 31, 2013 and is accounted for under the equity method of accounting.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents represent all highly liquid investments with original maturities of three months or less.
Accounts Receivable	'
	Accounts Receivable
	Accounts receivable are recorded at the invoiced amount and do not bear interest. Consistent with industry practice, the Company classifies unbilled receivables related to contracts accounted for under the long-term contract method of accounting, as current. The Company determines an allowance for doubtful accounts based on a review of outstanding receivables. Account balances are charged off against the allowance after the potential for recovery is considered remote. The Company's allowance for doubtful accounts was approximately $0.2 and $4.3 at December 31, 2013 and December 31, 2012, respectively.
	Accounts receivable, net includes unbilled receivables on long-term aerospace contracts, comprised principally of revenue recognized on contracts for which amounts were earned but not contractually billable as of the balance sheet date, or amounts earned in which the recovery will occur over the term of the contract, which could exceed one year.
Inventory	'
	Inventory
	Raw materials are stated at lower of cost (principally on an actual or average cost basis) or market. Inventoried costs attributed to units delivered under long-term contracts are based on the estimated average cost of all units expected to be produced and are determined under the learning curve concept which anticipates a predictable decrease in unit costs as tasks and production techniques become more efficient through repetition and supply chain costs are reduced as contracts are negotiated and design changes result in lower cost. This usually results in an increase in inventory (referred to as "excess-over-average" or "deferred production costs") during the early years of a contract. These costs are deferred only to the extent the amount of actual or expected excess-over-average is reasonably expected to be fully offset by lower-than-average costs in future periods of a contract. If in-process inventory plus estimated costs to complete a specific contract exceed the actual plus anticipated remaining sales value of such contract, such excess is charged to cost of sales in the period the loss becomes known, thus reducing inventory to estimated realizable value. Costs in inventory include amounts relating to contracts with long production cycles, some of which are not expected to be realized within one year.
	The Company reviews its general stock materials and spare parts inventory each quarter to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends and expected production usage. Impaired inventories are written off to work-in-process in the period identified.
	Total inventory includes deferred production costs for the excess of production costs over the estimated average cost per ship set, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per ship set for units delivered under the current production blocks. Recovery of excess over average deferred production costs is dependent on the number of ship sets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. Work-in-process inventory also includes non-recurring production costs. Non-recurring production costs include design and engineering costs and test articles.
	Finished goods inventory is stated at its estimated average per unit cost based on all units expected to be produced.
	Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant customer directed work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a certain number of ship set deliveries.
Property, Plant and Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is applied using a straight-line method over the useful lives of the respective assets as described in the following table:
		Estimated Useful Life
	Land improvements	20 years
	Buildings	45 years
	Machinery and equipment	3-20 years
	Tooling — Airplane program — B787, Rolls-Royce	5-20 years
	Tooling — Airplane program — all others	2-10 years
	Capitalized software	3-7 years
	We capitalize certain costs, such as software coding, installation and testing, that are incurred to purchase or to create and implement internal-use computer software in accordance with FASB authoritative guidance pertaining to capitalization of cost for internal-use software. Our capitalization policy includes specifications that the software must have a service life greater than one year, is legally and substantially owned by Spirit, and has an acquisition cost of greater than $0.1.
Intangible Assets and Goodwill	'
	Intangible Assets
	Intangible assets are initially recorded at estimated fair value and are comprised of patents, favorable leasehold interests, and customer relationships that are amortized on a straight-line basis over their estimated useful lives, ranging from 6 to 16 years for patents, 14 to 24 years for favorable leasehold interests, and 8 years for customer relationships.
Impairment or Disposal of Long-Lived Assets, and Goodwill	'
	Impairment or Disposal of Long-Lived Assets and Goodwill
	Spirit reviews capital and amortizing intangible assets (long-lived assets) for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable in accordance with FASB authoritative guidance on accounting for the impairment or disposal of long-lived assets. Under the standard, assets must be classified as either held-for-use or available-for-sale. An impairment loss is recognized when the carrying amount of an asset that is held for use exceeds the projected undiscounted future net cash flows expected from its use and disposal, and is measured as the amount by which the carrying amount of the asset exceeds its fair value, which is measured by discounted cash flows when quoted market prices are not available. For assets available-for-sale, an impairment loss is recognized when the carrying amount exceeds the fair value less cost to sell. The Company performs an annual impairment test for goodwill in the fourth quarter of each year, in accordance with FASB authoritative guidance pertaining to goodwill and other intangible assets, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below current value. Recent impairment testing has indicated no need for impairment.
Deferred Financing Costs	'
	Deferred Financing Costs
	Costs relating to long-term debt are deferred and included in other long-term assets. These costs are amortized over the term of the related debt or debt facilities, and are included as a component of interest expense.
Derivative Instruments and Hedging Activities	'
	Derivative Instruments and Hedging Activity
	We use derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates and interest rates. To account for our derivative financial instruments, we follow the FASB guidance on accounting for derivatives and hedges. Derivative financial instruments are recognized on the Consolidated Balance Sheets as either assets or liabilities and are measured at fair value. Changes in fair value of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedge transaction, and if it is, the type of hedge transaction. Gains and losses on derivative instruments reported in other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item or when the hedge is no longer effective. We present the cash flows associated with our derivatives as a component of the operating or investing sections of the statement of cash flows. Our use of derivatives has generally been limited to interest rate swaps and foreign currency forward contracts. The Company enters into foreign currency forward contracts to reduce the risks associated with the changes in foreign exchange rates on sales and cost of sales denominated in currencies other than the entities' functional currency.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Financial instruments are measured in accordance with FASB authoritative guidance related to fair value measurements. This guidance clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about fair value measurements. See Note 12, "Fair Value Measurements."
Income Taxes	'
	Income Taxes
	Income taxes are accounted for in accordance with FASB authoritative guidance on accounting for income taxes. Deferred income tax assets and liabilities are recognized for the future income tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to reduce deferred income tax assets to an amount that in management's opinion will ultimately be realized. Tax rate changes impacting these assets and liabilities are recognized in the period during which the rate change occurs.
	We record an income tax expense or benefit based on the net income earned or net loss incurred in each tax jurisdiction and at the tax rate applicable to that income or loss. In the ordinary course of business, there are transactions for which the ultimate tax outcome is uncertain. These uncertainties are accounted for in accordance with FASB authoritative guidance on accounting for the uncertainty in income taxes. The final tax outcome for these matters may be different than management's original estimates made in determining the income tax provision. A change to these estimates could impact the effective tax rate and net income or loss in subsequent periods. We use the flow-through accounting method for tax credits. Under this method, tax credits reduce income tax expense.
Stock-Based Compensation and Other Share-based Payments	'
	Stock-Based Compensation and Other Share-Based Payments
	Many of the Company's employees are participants in various stock compensation plans. The Company accounts for stock option plans, restricted share plans and other stock-based payments in accordance with FASB authoritative guidance pertaining to share-based payment. The expense attributable to the Company's employees is recognized over the period the amounts are earned and vested, as described in Note 18 "Stock Compensation."
Service and Product Warranties And Extraordinary Rework Provision	'
	Service and Product Warranties and Extraordinary Rework
	Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These estimates are established using historical information on the nature, frequency and average cost of warranty claims.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update ("ASU") No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (FASB ASU 2013-11). This update was issued to give explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The provisions of FASB ASU 2013-11 are effective for fiscal years and interim periods beginning after December 15, 2013. The adoption of the provisions of this update will not have a material impact on the Company’s consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes (FASBASU 2013-10). The amendments in this update permit the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge accounting purposes, in addition to UST and LIBOR. The amendments also remove the restriction on using different benchmark rates for similar hedges. The amendment is effective for qualifying new or redesignated hedging relationship entered into on or after July 17, 2013. The adoption of the provisions of ASU 2013-10 did not have a material impact on the Company’s consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (FASB ASU 2013-02). The amendment in this update requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. The provisions of FASB ASU 2013-02 were effective for annual and interim periods beginning after December 15, 2012. The adoption of the provisions of FASB ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements.
	In July 2012, the FASB issued ASU No. 2012-2, Intangibles — Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (FASB ASU 2012-2). The amendment in this update permits an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles — Goodwill and Other — General Intangibles Other than Goodwill. The provisions of FASB ASU 2012-2 were effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012. The adoption of the provisions of FASB ASU 2012-2 did not have a material impact on the Company's consolidated financial statements.
	In December 2011, the FASB issued ASU 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities (FASB ASU 2011-11). The amendments in this update require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The intention is to enhance required disclosures by improving information about financial instruments and derivative instruments that are either offset in accordance with FASB guidance or are subject to an enforceable master netting arrangement; irrespective of whether they are offset in accordance with FASB guidance. The provisions of FASB ASU 2011-11 have been effective for annual reporting periods beginning on or after January 1, 2013. The adoption of the provisions of FASB ASU 2011-11 has not had a material impact on the Company's consolidated financial statements.

	-1	Forward loss charges taken since January 1, 2012 on blocks that have not closed.
	-2	Forward loss charges taken through December 31, 2011 were reflected within capitalized pre-production and inventory for the respective programs and are therefore not reflected as part of the Forward Loss Provision figure presented. The cumulative forward loss charges, net of contract liabilities, through December 31, 2013 on open blocks are $123.8, $463.1 and $29.0 for the A350 XWB, G280 and Sikorsky programs, respectively.
	-3	Forward loss provision of $41.1 recorded on the fuselage portion of the B747 program in 2013 included $21.2 of charges on the subsequent planning block. The total provision exceeded the inventory balance which resulted in a contract liability of $3.9 which will be reduced as additional contact costs are incurred.
	-4	Forward loss provision of $11.6 recorded in 2013 on the B767 program of which $7.5 related to propulsion which exceeded the inventory balance for the propulsion portion of the program. The excess of charge over program inventory was classified as a contract liability of $5.8 which will be reduced as additional contract costs are incurred. Forward loss provision of $8.0 recorded on the B767 program in the fourth quarter of 2012 exceeded the total inventory balance. The excess of the charge over program inventory was classified as a contract liability of $1.5 as of December 31, 2012 and was reduced to zero as additional inventory was generated as of June 27, 2013.
	-5	Forward loss provision of $32.7 recorded on the non-recurring fuselage portion of the A350-1000 XWB program in 2013 exceeded the total inventory balance. The excess of the charge over the program inventory is classified as a contract liability of $7.7, reduced to zero as additional inventory was generated as of December 31, 2013. This liability was reported in other current liabilities and was absorbed back into the forward loss category of inventory as inventory on the non-recurring portion of the program increased. In 2013, non-recurring in the amount of $17.9 was reclassified to capitalized pre-prodution.
	-6	Forward loss provision of $240.9 recorded in 2013 exceeded the total inventory balance. The excess of the charge over program inventory is classified as a contract liability. The total contract liability as of December 31, 2013 is $74.2. This contract liability is reported in other current liabilities. This liability will flow back into the forward loss category of inventory as inventory on the program increases.
	-7	Forward loss provision of $151.0 recorded in 2012 exceeded the total inventory balance. The excess of the charge over program inventory is classified as a contract liability. In 2013 a forward loss provision of $21.7 and forward loss reduction of $8.4 was recorded, the net of which increased the contract liability from 2012. The total contract liability is $36.7 as of December 31, 2013. This contract liability is reported in other current liabilities. This liability will flow back into the forward loss category of inventory as inventory on the program increases.
	-8	Includes over-applied and under-applied overhead.

	Multi-employer Pension Plan
	In connection with the collective bargaining agreement signed with the International Association of Machinists and Aerospace Workers (IAM), the Company contributes to a multi-employer defined benefit pension plan (IAM National Pension Fund). The level of contribution, as specified in the bargaining agreement was $1.35 per hour of employee service for a maximum of 80 hours per bi-weekly pay period through June 30, 2010. Effective July 1, 2010 the contribution per the collective bargaining agreement is $1.50 per hour of employee service for a maximum of 80 hours per bi-weekly pay period. The IAM bargaining agreement provides for a $0.05 increase per hour in the contribution rate beginning on July 1, 2011, with an additional $0.05 increase effective July 1 of each year through 2019.
	The collective bargaining agreement with the UAW requires the Company to contribute a specified amount per hour of service to a multi-employer defined benefit pension plan (IAM National Pension Fund). The specified amount was $1.30 in 2010. Per the negotiated UAW collective bargaining agreement, the pension contributions will be as follows:
	Effective 1/1/2011 — $1.45
	Effective 1/1/2012 — $1.50
	Effective 1/1/2014 — $1.55
	Effective 1/1/2016 — $1.60
	Effective 1/1/2018 — $1.65
	Effective 1/1/2019 — $1.70
	Effective 1/1/2020 — $1.75
	The risk of this multi-employer plan is different from single-employer plans in the following aspects:
	1	Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers.
	2	If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
	3	If the Company chooses to stop participating in the multi-employer plan, the Company may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
	The following table summarizes the multi-employer plan to which the Company contributes:

	The components of the pension benefit plan expense for the U.K. plans and the assumptions used to determine benefit obligations for 2013, 2012 and 2011 are as follows:

	Total recognized in net periodic benefit cost and OCI	$	(2.9	)		$	1.6		$	10.8
	Assumptions used to determine net periodic benefit costs:
	Discount rate	4.7		%		4.8		%	5.3		%
	Expected return on plan assets	5.8		%		5.8		%	6.1		%
	Salary increases	3.1		%		3.2		%	3.55		%
	The estimated net (gain) loss that will be amortized from other comprehensive income into net periodic benefit cost over the next fiscal year for the U.K. plan is zero.
	Assumptions
	The Company sets the discount rate assumption annually for each of its retirement-related benefit plans as of the measurement date, based on a review of projected cash flow and a long-term high-quality corporate bond yield curve. The discount rate determined on each measurement date is used to calculate the benefit obligation as of that date, and is also used to calculate the net periodic benefit (income)/cost for the upcoming plan year.
	The pension expected return on assets assumption is derived from the long-term expected returns based on the investment allocation by class specified in the Company's investment policy. The expected return on plan assets determined on each measurement date is used to calculate the net periodic benefit (income)/cost of the upcoming plan year.
	Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. To determine the health care cost trend rates the Company considers national health trends and adjusts for its specific plan design and locations.
	A one-percentage point increase in the initial through ultimate assumed health care trend rates would have increased the accumulated post-retirement benefit obligation by $5.7 at December 31, 2013 and the aggregate service and interest cost components of non-pension post-retirement benefit expense for 2013 by $0.4. A one-percentage point decrease would have decreased the obligation by $5.2 and the aggregate service and interest cost components of non-pension post-retirement benefit expense for 2013 by $0.4.

Pension Plan Assets Measured at Fair Value on a Recurring Basis	'
	Fair Value Measurements
	The pension plan assets are valued at fair value. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy.
	Temporary Cash Investments — These investments consist of U.S. dollars and foreign currencies held in master trust accounts. Foreign currencies held are reported in terms of U.S. dollars based on currency exchange rates readily available in active markets. These temporary cash investments are classified as level 1 investments.
	Collective Investment Trusts — These investments are public investment vehicles valued using middle market prices and performance of the fund. The trust allocates notional units to the policy holder based on the underlying notional unit buy (offer) price using the middle market price plus transaction costs. These investments are classified within level 2 of the valuation hierarchy. In addition, the collective investment trust includes a real estate fund which is classified within level 3 of the valuation hierarchy.
	Commingled Equity and Bond Funds — These investments are valued at the closing price reported by the Plan Trustee. These investments are not being traded in an active market, but are backed by various investment securities managed by the Bank of New York. Fair value is being calculated using unobservable inputs that rely on the Bank of New York's own assumptions and are therefore classified within level 2 of the valuation hierarchy, although these assumptions are based on underlying investments which are traded on an active market.
	As of December 31, 2013 and December 31, 2012, the pension plan assets measured at fair value on a recurring basis were as follows:

Defined Contribution Plan [Abstract]	'	'	'	'
Defined Contribution Plan	'	'Defined Benefit Pension PlansEffective JuneB 17, 2005, pension assets and liabilities were spun-off from three Boeing qualified plans into four qualified Spirit AeroSystems plans for each Spirit employee who did not retire from Boeing by AugustB 1, 2005. Effective DecemberB 31, 2005, all four qualified plans were merged together. In addition, Spirit has one nonqualified plan providing supplemental benefitsto executives (SERP) who transferred from a Boeing nonqualified plan to a Spirit AeroSystems plan and elected to keep their benefits in this plan. Both plans are frozen as of the date of the Boeing Acquisition (i.e.,B no future service benefits are being earned in these plans). We intend to fund our qualified pension plan through a trust. Pension assets are placed in trust solely for the benefit of the pension plans' participants and are structured to maintain liquidity that is sufficient to pay benefit obligations.	'	'
Company contribution	'	39.1	39.5	38.4
Defined Contribution Plan Description	'	'The Company contributes to a defined contribution plan available to all U.S. employees, excluding IAM and UAW represented employees. Under the plan, the Company makes a matching contribution of 75% of the employee contribution to a maximum 8% of eligible individual employee compensation. In addition, non-matching contributions based on an employee's age and years of service are paid at the end of each calendar year for certain employee groups.The Company recorded $39.1, $39.5 and $38.4 in contributions to these plans for the twelve months ended DecemberB 31, 2013, DecemberB 31, 2012 and DecemberB 31, 2011, respectively.

Defined Contribution Plan [Abstract]	'	'	'	'
Defined Contribution Plan	'	'On AprilB 1, 2006, as part of the acquisition of BAE Aerostructures, the Company established a defined benefit pension plan for those employees that had pension benefits remaining in BAE Systems' pension plan.B In accordance with U.K. legislation, the plan and its assets are managed by an independent trustee company.B The investment strategy adopted by this trustee is documented in a Statement of Investment Principles in line with U.K. legislation. The principles for the investment strategy are to maximize the long-term rate of return on plan assets within an acceptable level of risk while maintaining adequate funding levels. The trustee has invested the plan assets in pooled arrangements with authorized investment companies which were selected to be consistent with the plan's overall investment principles and strategy. The specified target asset allocation is 55% equities, 5% real estate, 20% corporate bonds and 20% government bonds. B Effective December 31, 2013, the U.K. pension plan was closed and benefits were frozen and thereafter subject only to statutory pension revaluation, resulting in a net curtailment gain of $13.1. This gain was due to the loss of salary linkage for employed members of the plan, less the cost of other benefit changes made as part of the plan closure. On AprilB 1, 2006, as part of the acquisition of BAE Aerostructures, the Company established a defined contribution pension plan for those employees who are hired after the date of acquisition. Under the plan, the Company contributes 8% of basic salary while participating employees are required to contribute 4% of basic salary. The Company recorded $1.8 in contributions to this plan for the period ended DecemberB 31, 2013, $0.8 in contributions for the period ended DecemberB 31, 2012 and $0.7 in contributions for the period ended DecemberB 31, 2011.

Description of Multiemployer Plan	'	'Other Post-Retirement Benefit PlansWe also have post-retirement health care coverage for eligible U.S. retirees and qualifying dependents prior to age 65. Eligibility for employer-provided benefits is limited to those employees who were employed at the date of acquisition (Spirit) and retire on or after attainment of age 62 and 10 yearsB of service. Employees who do not satisfy these eligibility requirements can retire with post-retirement medical benefits at age 55 and 10 yearsB of service, but they must pay the full cost of medical benefits provided.
