Accounting Policies [Abstract]
Accounting Policies	ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for allowances for doubtful accounts, sales returns reserve, allowances for inventory valuation, warranty costs, investments, goodwill impairment, intangibles impairment, purchased intangibles, stock-based compensation, and income taxes among others. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the company in the future, actual results may differ materially from management’s estimates. Basis of Presentation The Company has a 52-53 week fiscal year, ending on the Friday nearest to December 31. Fiscal 2015 and 2014 were both 52-week years, and ended on January 1, 2016 and January 2, 2015, respectively. Fiscal 2013 was a 53-week year and ended on January 3, 2014. Unless otherwise stated, all dates refer to the Company’s fiscal year. These Consolidated Financial Statements include the results of the Company and its consolidated subsidiaries. Inter-company accounts and transactions have been eliminated. Noncontrolling interests represent the noncontrolling shareholders’ proportionate share of the net assets and results of operations of the Company’s consolidated subsidiaries. The Company has presented revenue and cost of sales separately for products, service and subscriptions. Product revenue includes hardware, software licenses, parts and accessories; service revenue includes maintenance and support for hardware and software products, training and professional services; subscription revenue includes software as a service (SaaS). Historically, the Company allocated stock-based compensation to each segment. Beginning with the first quarter of fiscal 2015, the Company changed its methodology for allocating stock-based compensation to its segments. Stock-based compensation is shown in the aggregate within unallocated corporate expense and is not reflected in the segment results, which is consistent with the way the Chief Operating Decision Maker (CODM) evaluates each of the segment's performance and allocates resources. The Company has adjusted the presentation of previously reported segment information to conform to the current year methodology within Note 7. In the third quarter of fiscal 2015, the Company identified an error in its previously reported financial statements with regard to a portion of its goodwill balance arising from deferred tax liabilities in foreign jurisdictions that had not been properly translated to U.S. dollars. As a result, both goodwill and the cumulative translation adjustment included in Accumulated other comprehensive loss on the Consolidated Balance Sheets were overstated and the resulting foreign currency translation adjustment component of Other comprehensive loss was incorrect. There was no impact on Net Income or Cash Flows. The Company evaluated the impact of the error, both quantitatively and qualitatively, and concluded that the differences were not material individually or in the aggregate to any of the prior reporting periods. The impact has no effect on Net Income or Cash Flows, but in light of the significance of the cumulative amount of the error on comprehensive income on the full year 2015, the Company has revised previously issued financial information for periods contained in this Annual Report on Form 10-K to correct for the foreign currency translation figures. Interim periods not presented herein will be revised, as applicable, when they are included in future filings. See Note 17 of the Notes to Consolidated Financial Statements for further information. Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in local currencies are translated to U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive income, net of tax in accumulated other comprehensive loss within the shareholders’ equity section of the Consolidated Balance Sheets. Income and expense accounts are translated at average monthly exchange rates during the year. Derivative Financial Instruments The Company enters into foreign exchange forward contracts to minimize the short-term impact of foreign currency fluctuations on cash, certain trade and inter-company receivables and payables, primarily denominated in Australian, Canadian, Singapore and New Zealand Dollars, Japanese Yen, Chinese Yuan, Indian Rupee, Brazilian Real, South African Rand, Swedish Krona, Swiss Franc, Euro and British pound. These contracts reduce the exposure to fluctuations in exchange rate movements as the gains and losses associated with foreign currency balances are generally offset with the gains and losses on the forward contracts. These instruments are marked to market through earnings every period and generally range from one to two months in original maturity. The Company occasionally enters into foreign exchange forward contracts to hedge the purchase price of some of its larger business acquisitions. The Company does not enter into foreign exchange forward contracts for trading purposes. As of the fiscal years ended 2015 and 2014, there were no derivative financial instruments outstanding that were accounted for as hedges. Cash and Cash Equivalents Cash and cash equivalents include all cash and highly liquid investments with insignificant interest rate risk and maturities of three months or less at the date of purchase. The carrying amount of cash and cash equivalents approximates fair value because of the short maturity of those instruments. Concentration of Risk Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and therefore bear minimal credit risk. The Company is also exposed to credit risk in the Company’s trade receivables, which are derived from sales to end-user customers in diversified industries as well as various resellers. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary but generally does not require collateral. With Flextronics Corporation International as an exclusive manufacturing partner for many of its products, the Company is dependent upon a sole supplier for the manufacture of these products. In addition, the Company relies on sole suppliers for a number of its critical components. Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company evaluates the ongoing collectibility of its trade accounts receivable based on a number of factors such as age of the accounts receivable balances, credit quality, historical experience, and current economic conditions that may affect a customer’s ability to pay. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations to the Company, a specific allowance for bad debts is estimated and recorded which reduces the recognized receivable to the estimated amount that the Company believes will ultimately be collected. In addition to specific customer identification of potential bad debts, bad debt charges are recorded based on the Company’s recent past loss history and an overall assessment of past due trade accounts receivable amounts outstanding. Inventories Inventories are stated at the lower of cost or market. Adjustments are also made to reduce the cost of inventory for estimated excess or obsolete balances. Factors influencing these adjustments include declines in demand which impact inventory purchasing forecasts, technological changes, product life cycle and development plans, component cost trends, product pricing, physical deterioration and quality issues. If the Company's estimates used to reserve for excess and obsolete inventory are different from what it expected, the Company may be required to recognize additional reserves, which would negatively impact its gross margin. Property and Equipment, Net Property and equipment, net is stated at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the shorter of the estimated useful lives or the lease terms when applicable. Useful lives generally include a range from four to six years for machinery and equipment, five to seven years for furniture and fixtures, two to five years for computer equipment and software, 39 years for buildings, and the life of the lease for leasehold improvements. The Company capitalizes eligible costs to acquire or develop internal-use software that are incurred subsequent to the preliminary project stage. Capitalized costs related to internal-use software are amortized using the straight-line method over the estimated useful lives of the assets, which range generally from two to five years. The costs of repairs and maintenance are expensed when incurred, while expenditures for refurbishments and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Depreciation expense was $36.7 million in fiscal 2015 , $33.1 million in fiscal 2014 and $26.7 million in fiscal 2013 . Business Combinations The Company allocates the fair value of purchase consideration to the assets acquired, liabilities assumed, and non-controlling interests in the acquiree based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired, liabilities assumed and non-controlling interests in the acquiree is recorded as goodwill. When determining the fair values of assets acquired, liabilities assumed, and non-controlling interests in the acquiree, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing intangible assets include, but are not limited to, expected future cash flows, which includes consideration of future growth rates and margins, customer attrition rates, future changes in technology and brand awareness, loyalty and position, and discount rates. Fair value estimates are based on the assumptions management believes a market participant would use in pricing the asset or liability. Amounts recorded in a business combination may change during the measurement period, which is a period not to exceed one year from the date of acquisition, as additional information about conditions existing at the acquisition date becomes available. Goodwill and Purchased Intangible Assets Goodwill represents the excess of the purchase consideration over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets acquired individually, with a group of other assets, or in a business combination are recorded at fair value. Identifiable intangible assets are comprised of distribution channels and distribution rights, patents, licenses, technology, acquired backlog, trademarks and in-process research and development. Identifiable intangible assets are being amortized over the period of estimated benefit using the straight-line method, reflecting the pattern of economic benefits associated with these assets, and have estimated useful lives ranging from one month to twelve years with a weighted average useful life of 6.2 years. Goodwill is not subject to amortization, but is subject to at least an annual assessment for impairment, applying a fair-value based test. Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets The Company evaluates goodwill, at a minimum, on an annual basis and whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. The Company performs its annual goodwill impairment testing in the fourth fiscal quarter of each year based on the values on the first day of that quarter. For the Company's annual goodwill impairment test in the fourth quarter of fiscal 2015 goodwill was reviewed for impairment utilizing a quantitative two-step process. In the first step of this test, goodwill is tested for impairment at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated using a discounted cash flow approach. If the carrying amount of the reporting unit exceeds its fair value, a second step is performed to measure the amount of impairment loss, if any. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting unit’s goodwill, the difference is recognized as an impairment loss. When the Company performs a quantitative assessment of goodwill impairment, the determination of fair value of a reporting unit involves the use of significant estimates and assumptions. The discounted cash flows are based upon, among other things, assumptions about expected future operating performance using risk-adjusted discount rates. Actual future results may differ from those estimates. As of the first day of the fourth quarter of fiscal 2015, the fair value for our reporting units ranged from 131% to approximately 701% of carrying amounts, therefore goodwill was not impaired and no further testing was required. For certain earlier stage reporting units, due to the smaller magnitude of the carrying value and fair value of each respective reporting unit, the margins by which the fair value exceeded the carrying value on an absolute dollar basis were relatively small. Depreciation and amortization of the Company’s intangible assets and other long-lived assets is provided using the straight-line method over their estimated useful lives, reflecting the pattern of economic benefits associated with these assets. Changes in circumstances such as technological advances, changes to the Company’s business model, or changes in the capital strategy could result in the actual useful lives differing from initial estimates. In cases where the Company determines that the useful life of an asset should be revised, the Company will depreciate the net book value in excess of the estimated residual value over its revised remaining useful life. These assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance and these estimates may differ from actual future cash flows. The assets evaluated for impairment are grouped with other assets to the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. If the sum of the projected undiscounted cash flows (excluding interest) is less than the carrying value of the assets, the assets will be written down to the estimated fair value. Warranty The Company accrues for warranty costs as part of its cost of sales based on associated material product costs, technical support labor costs, and costs incurred by third parties performing work on the Company’s behalf. The Company’s expected future cost is primarily estimated based upon historical trends in the volume of product returns within the warranty period and the cost to repair or replace the equipment. When products sold include warranty provisions, they are covered by a warranty for periods ranging generally from 1 year to 2 years. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers, its warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage, or service delivery costs differ from the estimates, revisions to the estimated warranty accrual and related costs may be required. Changes in the Company’s product warranty liability during the fiscal years ended 2015 and 2014 are as follows: At the End of Fiscal Year 2015 2014 (In millions) Beginning balance $ 20.6 $ 17.8 Acquired warranties 0.1 — Accruals for warranties issued 16.6 22.8 Changes in estimates 4.8 2.6 Warranty settlements (in cash or in kind) (23.6 ) (22.6 ) Ending Balance $ 18.5 $ 20.6 Guarantees, Including Indirect Guarantees of Indebtedness of Others In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, lessors, and parties to other transactions with the Company. For example, the Company has agreed to hold the other party harmless against losses arising from a breach of representations or covenants, or out of intellectual property infringement or other claims made by certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents. It is not possible to determine the maximum potential exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not been material and no liabilities have been recorded on the Consolidated Balance Sheets at the end of fiscal 2015 and 2014 . Revenue Recognition The Company recognizes revenue when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is reasonably assured. In instances where final acceptance of the product is specified by the customer or is uncertain, revenue is deferred until all acceptance criteria have been met. Contracts and/or customer purchase orders are used to determine the existence of an arrangement. Shipping documents and customer acceptance, when applicable, are used to verify delivery. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. The Company assesses collectibility based primarily on the creditworthiness of the customer as determined by credit checks and analyses, as well as the customer’s payment history. Revenue for orders is not recognized until the product is shipped and title has transferred to the buyer. The Company bears all costs and risks of loss or damage to the goods up to that point. The Company’s shipment terms for U.S. orders and international orders fulfilled from the Company’s European distribution center typically provide that title passes to the buyer upon delivery of the goods to the carrier named by the buyer at the named place or point. If no precise point is indicated by the buyer, delivery is deemed to occur when the carrier takes the goods into its charge from the place determined by the Company. Other shipment terms may provide that title passes to the buyer upon delivery of the goods to the buyer. Shipping and handling costs are included in Cost of sales. Revenue from sales to distributors and dealers is recognized upon shipment, assuming all other criteria for revenue recognition have been met. Distributors and dealers do not have a right of return. Revenue from purchased extended warranty and post contract support (PCS) agreements is deferred and recognized ratably over the term of the warranty or support period. Revenue from the Company's subscription services related to its hardware and software applications is recognized ratably over the term of the subscription service period beginning on the date that service is made available to the customer, assuming all revenue recognition criteria have been met. The Company presents revenue net of sales taxes and any similar assessments. The Company’s software arrangements generally consist of a perpetual license fee and PCS. The Company generally has established vendor-specific objective evidence (VSOE) of fair value for the Company’s PCS contracts based on the renewal rate. The remaining value of the software arrangement is allocated to the license fee using the residual method. License revenue is primarily recognized when the software has been delivered and fair value has been established for all remaining undelivered elements. In cases where VSOE of fair value for PCS is not established, revenue is recognized ratably over the PCS period after all software deliverables have been made and the only the undelivered element is PCS. For services performed on a fixed-fee basis, revenue is recognized using the proportional performance method, with performance measured based on hours of work performed. For contracts that involve significant customization and implementation or consulting services that are essential to the functionality of the software, the license and services revenues are recognized using the percentage-of-completion method or, if we are unable to reliably estimate the costs to complete the services, we use the completed-contract method of accounting. A contract is considered complete when all significant costs have been incurred or when acceptance from the customer has been received. Some of the Company’s subscription product offerings include hardware, subscription services and extended warranty. Under these hosted arrangements, the customer typically does not have the contractual right to take possession of the software at any time during the hosting period without incurring a significant penalty and it is not feasible for the customer to run the software either on its own hardware or on a third-party’s hardware. The Company’s multiple deliverable product offerings include hardware with embedded firmware, extended warranty, software, PCS and subscription services, which are considered separate units of accounting. For certain of the Company’s products, software and non-software components function together to deliver the tangible product’s essential functionality. In evaluating the revenue recognition for the Company's hardware or subscription agreements which contain multiple deliverables, the Company determined that in certain instances the Company was not able to establish VSOE for some or all deliverables in an arrangement as the Company infrequently sold each element on a standalone basis, did not price products within a narrow range, or had a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on relevant third-party evidence (TPE). TPE is determined based on competitor prices for similar deliverables when sold separately. The Company’s offerings may contain a significant level of proprietary technology, customization or differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company typically is not able to establish the selling price of an element based on TPE. When the Company is unable to establish selling price using VSOE or TPE, the Company uses its best estimate of selling price (BESP) in the Company’s allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings. The Company determines BESP for a product or service by considering multiple factors including, but not limited to, pricing practices, market conditions, competitive landscape, internal costs, geographies and gross margin. The determination of BESP is made through consultation with and formal approval by the Company’s management, taking into consideration the Company’s go-to-market strategy. Advertising Costs The Company expenses all advertising costs as incurred. Advertising expense was approximately $32.3 million , $39.0 million , and $33.8 million , in fiscal 2015 , 2014 and 2013 , respectively. Research and Development Costs Research and development costs are charged to expense as incurred. Cost of software developed for external sale subsequent to reaching technical feasibility were not significant and were expensed as incurred. The Company received third party funding of approximately $12.5 million , $13.5 million , and $5.1 million in fiscal 2015 , 2014 and 2013 , respectively. The Company offsets research and development expense with any third party funding earned. The Company retains the rights to any technology developed under such arrangements. Stock-Based Compensation The Company has employee stock benefit plans, which are described more fully in “Note 13: Employee Stock Benefit Plans.” Stock compensation expense recognized in the Consolidated Statements of Income is based on the fair value of the portion of share-based payment awards that is expected to vest during the period and is net of estimated forfeitures. The Company attributes the value of stock options to expense using the straight-line single option method. The grant date fair value for options is estimated using the binomial valuation model. The fair value of rights to purchase shares under the Employee Stock Purchase Plan is estimated using the Black-Scholes option-pricing model. The fair value of restricted stock units is valued as of the grant date using the fair value of Trimble’s common stock. The fair value for restricted stock units with market-based vesting conditions is valued as of the grant date using a Monte Carlo simulation. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records stock-based compensation expense only for those awards that are expected to vest. Income Taxes Income taxes are accounted for under the liability method whereby deferred tax assets or liability account balances are calculated at the balance sheet date using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not such assets will not be realized. The Company’s valuation allowance is primarily attributable to foreign net operating losses and state research and development credit carryforwards. Management believes that it is more likely than not that the Company will not realize certain of these deferred tax assets, and, accordingly, a valuation allowance has been provided for such amounts. Valuation allowance adjustments associated with an acquisition after the measurement period are recorded through income tax expense. Relative to uncertain tax positions, the Company only recognizes a tax benefit if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and may not accurately forecast actual tax audit outcomes. Determining whether an uncertain tax position is effectively settled requires judgment. Changes in recognition or measurement of the Company's uncertain tax positions would result in the recognition of a tax benefit or an additional charge to the tax provision. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company is subject to income taxes in the U.S. and numerous other countries, and is subject to routine corporate income tax audits in many of these jurisdictions. The Company generally believes that positions taken on its tax returns are more likely than not to be sustained upon audit, but tax authorities in some circumstance have, and may in the future, successfully challenge these positions. Accordingly, the Company’s income tax provision includes amounts intended to satisfy assessments that may result from these challenges. Determining the income tax provision for these potential assessments and recording the related effects requires management judgments and estimates. The amounts ultimately paid on resolution of an audit could be materially different from the amounts previously included in the Company’s income tax provision and, therefore, could have a material impact on its income tax provision, net income and cash flows. The Company’s accrual for uncertain tax positions includes uncertainties concerning the tax treatment of our international operations, including the allocation of income among different jurisdictions, intercompany transactions and related interest. See Note 11 to the Consolidated Financial Statements for additional information. Computation of Earnings Per Share The number of shares used in the calculation of basic earnings per share represents the weighted average common shares outstanding during the period and excludes any potentially dilutive securities. The dilutive effects of outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan and restricted stock units are included in diluted earnings per share. Recent Accounting Pronouncements In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The Company adopted the amendments beginning in the first quarter of fiscal 2015. The adoption did not have a material impact on the Company’s Condensed Consolidated Financial Statements. In May 2014, the FASB issued a comprehensive new revenue recognition standard that replaces the current revenue recognition guidance under U.S. GAAP. The new standard requires companies to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The revised effective date for the Company under the new standard will be the beginning of fiscal 2018, with early adoption permitted as of the original effective date. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company is currently evaluating the effect of the updated standard on its consolidated financial statements and related disclosures. In February 2015, the FASB issued amendments to the consolidation guidance. The amendments under the new guidance modify the evaluation of whether limited partnerships and similar legal entities are v

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is computed by dividing Net income by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing Net income by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan and restricted stock units. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. The following table shows the computation of basic and diluted earnings per share: Fiscal Years 2015 2014 2013 (Dollars in millions, except per share data) Numerator: Net income attributable to Trimble Navigation Limited $ 121.1 $ 214.1 $ 218.9 Denominator: Weighted average number of common shares used in basic earnings per share 255.8 260.1 256.6 Effect of dilutive securities 2.7 4.4 4.6 Weighted average number of common shares and dilutive potential common shares used in diluted earnings per share 258.5 264.5 261.2 Basic earnings per share $ 0.47 $ 0.82 $ 0.85 Diluted earnings per share $ 0.47 $ 0.81 $ 0.84 For fiscal 2015, 2014 and 2013 the Company excluded 6.1 million shares, 1.4 million shares and 3.1 million shares of outstanding stock options, respectively, from the calculation of diluted earnings per share because their effect would have been antidilutive.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments and Joint Ventures Disclosure [Text Block]	GAIN ON EQUITY SALE In October, 2008, VirtualSite Solutions (VSS), a business formed by the Company and Caterpillar began operations. Originally, the Company had a 65% ownership and Caterpillar had a 35% ownership in VSS. VSS develops software for fleet management and connected worksite solutions for both Caterpillar and Trimble and in turn, sells software subscription services to Caterpillar and Trimble, which are sold through Caterpillar's and the Company's respective distribution channels. For financial reporting purposes prior to 2014, VSS’s results of operations were consolidated with those of the Company, which were reported under the Engineering and Construction segment. Caterpillar’s 35% interest was included in the overall Consolidated Financial Statements as Noncontrolling interest. Effective January 4, 2014, the Company sold 15% of its ownership in VSS to Caterpillar resulting in both the Company and Caterpillar owning 50% of the VSS joint venture. After the sale the Company no longer held a controlling interest in VSS. The sale of the 15% ownership resulted in the deconsolidation of VSS and a gain in the amount of $15.1 million in the first quarter of fiscal 2014. Of this amount, $8.5 million relates to the remeasurement of the Company's retained interest in the joint venture to fair value which was measured using a combination of the income and market approaches. The total gain is included in Other income (loss), net on the Company's fiscal 2014 Consolidated Statements of Income. The Company's 50% investment in VSS is classified as an equity method investment.

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS During fiscal 2015 , 2014 and 2013 the Company acquired multiple businesses, all with cash consideration. The Consolidated Statements of Income include the operating results of the businesses from the dates of acquisition. During fiscal 2015, the Company acquired thirteen businesses, all with cash consideration, in its Engineering and Construction, Field Solutions and Mobile Solutions segments. The Consolidated Statements of Income include the operating results of the businesses from the dates of acquisitions. The acquisitions were not significant individually or in the aggregate. The purchase prices ranged from less than $2.0 million to $30.0 million . The largest acquisition was a Norwegian company specializing in BIM software for infrastructure design software solutions across the European region. In the aggregate, the businesses acquired during fiscal 2015 collectively contributed less than one percent to the Company's total revenue during fiscal 2015. During fiscal 2014, the Company acquired thirteen businesses across its Engineering and Construction, Field Solutions, and Mobile Solutions segments. The purchase prices ranged from less than $0.6 million to $83.1 million . The largest acquisitions were of a company that provides software solutions to Mechanical, Electrical and Plumbing (MEP) industry and a software provider for real estate and facility management within the Engineering and Construction segment. In the aggregate, the businesses acquired during fiscal 2014 collectively contributed less than one percent to the Company's total revenue during fiscal 2014. During fiscal 2013, the Company acquired sixteen businesses across its Engineering and Construction, Field Solutions and Mobile Solutions segments. The purchase prices ranged from less than $0.5 million to $80.0 million . The largest acquisitions were of a company that provides product and pricing information to the MEP industry within the Engineering and Construction segment, and a software for logistics providers within the Mobile Solutions segment. In the aggregate, the businesses acquired during fiscal 2013 collectively contributed less than three percent to the Company's total revenue during fiscal 2013. The Company determined the total consideration paid for each of its acquisitions as well as the fair value of the assets acquired and liabilities assumed as of the date of each acquisition. For certain acquisitions completed in fiscal 2015, the fair value of the assets acquired and liabilities assumed are preliminary and may be adjusted as the Company obtains additional information, primarily related to adjustments for the true up of acquired net working capital in accordance with certain purchase agreements, and estimated values of certain net tangible assets and liabilities including tax balances, pending the completion of final studies and analyses. If there are adjustments made for these items the fair value of intangible assets and goodwill could be impacted. Thus the provisional measurements of fair value set forth below are subject to change. Such changes could be significant. The Company expects to finalize the valuation of the net tangible and intangible assets as soon as practicable, but not later than one -year from the acquisition date. The fair value of identifiable assets acquired and liabilities assumed were determined under the acquisition method of accounting for business combinations. The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. The fair value of intangible assets acquired is generally determined based on a discounted cash flow analysis. Acquisition costs of $12.0 million , $13.4 million and $13.5 million in fiscal 2015 , 2014 and 2013 , respectively, were expensed as incurred and were included in General and administrative expenses in the Consolidated Statements of Income.

Segment Reporting, Measurement Disclosures [Abstract]
Reporting Segment And Geographic Information	REPORTING SEGMENT AND GEOGRAPHIC INFORMATION To achieve distribution, marketing, production, and technology advantages, the Company manages its operations in the following four segments: • Engineering and Construction: This segment primarily serves customers working in architecture, engineering, construction, geospatial and government. Within this segment our most substantial product portfolios are focused on civil engineering and construction, building construction, and geospatial. • Field Solutions: This segment provides solutions for the farming, government and consumer markets, with its products focused on agriculture and geographic information systems (GIS). • Mobile Solutions: This segment provides solutions that enable end-users to monitor and manage their mobile work, mobile workers and mobile assets in the areas of transportation and logistics and field services management. • Advanced Devices - The various operations that comprise this segment are aggregated on the basis that these operations, taken as a whole, do not exceed 10% of the Company's total revenue, operating income or assets. This segment is comprised of the Embedded Technologies, Timing, Applanix, Military and Advanced Systems and ThingMagic businesses. The Company’s CODM, its Chief Executive Officer, evaluates each of its segment’s performance and allocates resources based on segment operating income before income taxes and some corporate allocations. The Company and each of its segments employ consistent accounting policies. In each of its segments the Company sells many individual products. For this reason it is impracticable to segregate and identify revenue for each of the individual products or group of products. The following tables present revenue, operating income, depreciation expense and identifiable assets for the four segments. Operating income is revenue less cost of sales and operating expense, excluding general corporate expense, acquisition costs, amortization of purchased intangible assets, amortization of acquisition-related inventory step-up, restructuring charges, stock-based compensation and litigation reserves. The identifiable assets that the CODM views by segment are accounts receivable, inventories and goodwill.

Beginning with the first quarter of fiscal 2015, the Company changed its methodology for allocating stock-based compensation to its segments. Stock-based compensation is shown in the aggregate within unallocated corporate expense and not reflected in the segment results, which is consistent with the way the CODM evaluates each of the segment's performance and allocates resources. The Company has adjusted the presentation of segment information for fiscal 2014 and 2013 to conform to the current year methodology. The following table shows the amount of stock-based compensation that had been previously allocated to the business segments in the fiscal 2014 and 2013 and the impact to those segments' Operating income.

Long-term Debt, Unclassified [Abstract]
Long-Term Debt	DEBT Debt consisted of the following: At the End of Fiscal Year 2015 2014 (Dollars in millions) Notes: Principal amount $ 400.0 $ 400.0 Unamortized discount on Notes (2.8 ) (3.1 ) Debt issuance costs (2.7 ) (3.0 ) Credit Facilities: 2014 Credit facility 216.0 277.0 Uncommitted facilities 118.0 57.0 Promissory notes and other debt 1.2 7.5 Total debt 729.7 735.4 Less: Short-term debt 118.3 64.4 Long-term debt $ 611.4 $ 671.0 Notes On October 30, 2014 , the Company filed a shelf registration statement with the Securities and Exchange Commission (“SEC”) for the issuance of senior debt securities. On November 24, 2014 , the Company issued $400.0 million of Senior Notes (“Notes”) under the shelf registration statement. Net proceeds from the offering were $396.9 million after deducting the 0.795% discount on the public offering price. The Company recognized $3.0 million of debt issuance costs associated with the issuance of the Notes, including an underwriting discount of $2.6 million , which is classified as an offset to the Notes on the Consolidated Balance Sheets. The discount and debt issuance costs are being amortized to interest expense using the effective interest rate method over the term of the Notes. The Notes mature on December 1, 2024 and accrue interest at a rate of 4.75% per annum, payable semiannually in arrears in cash on December 1 and June 1 of each year, beginning on June 1, 2015. The Notes are classified as long-term in the Consolidated Balance Sheet. Prior to September 1, 2024, Trimble may redeem the Notes at its option at any time, in whole or in part, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of interest and principal, calculated on a semiannual basis using a discount rate equal to the U.S. Treasury rate plus 40 basis points. After September 1, 2024, Trimble may redeem the Notes at its option at any time, in whole or in part, at a redemption price equal to 100% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon. In addition, in the event of a change of control, as defined in the prospectus filed with the SEC, each holder of the Notes will have the right to require Trimble to purchase for cash all or a portion of such holder’s Notes at a purchase price equal to 101% of the principal amount of the Notes, plus any accrued and unpaid interest. In connection with the closing of the Notes offering, Trimble entered into an Indenture with U.S. Bank National Association, as trustee. The Indenture contains covenants limiting Trimble’s ability to create certain liens, enter into sale and lease-back transactions, and consolidate or merge with or into, or convey, transfer or lease all or substantially all of Trimble’s properties and assets to, another person, each subject to certain exceptions. The Notes contain no financial covenants. Credit Facilities 2014 Credit Facility On November 24, 2014 , the Company entered into a new five -year credit agreement with a group of lenders (the “2014 Credit Facility”). The 2014 Credit Facility provides for an unsecured revolving loan facility of $1.0 billion . Subject to the terms of the 2014 Credit Facility, the revolving loan facility may be increased and/or term loan facilities may be established in an amount up to $500.0 million . The outstanding balance of $216.0 million and $277.0 million is classified as long-term in the Consolidated Balance Sheet as of fiscal years ended 2015 and 2014, respectively. The 2014 Credit Facility replaced the Company's previous 2012 Credit Facility comprised of a five -year revolving loan facility of $700.0 million and a five -year $700.0 million term loan facility. Upon entering into the 2014 Credit Facility, the Company borrowed $307.0 million under the revolving loan facility. The Company used the proceeds from the revolving loan facility and the issuance of the Notes to pay off the then $638.8 million outstanding term loan balance under the 2012 Credit Facility. The Company also wrote off a portion of the unamortized debt issuance costs related to the 2012 Credit Facility totaling $2.7 million , which is classified as a non-operating expense in the Company’s fiscal 2014 Consolidated Statement of Income. In addition, the Company recognized $1.6 million of debt issuance costs associated with the 2014 Credit Facility. The remaining unamortized debt issuance costs associated with the 2012 Credit Facility and the new debt issuance costs associated with the 2014 Credit Facility are classified as current and non-current assets on the Consolidated Balance Sheets and being amortized to interest expense using the effective interest rate method over the term of the 2014 Credit Facility. The funds available under the 2014 Credit Facility may be used for working capital and general corporate purposes including stock repurchases and the financing of certain acquisitions. Under the 2014 Credit Facility, the Company may borrow, repay and reborrow funds under the revolving loan facility until its maturity on November 24, 2019 , at which time the revolving facility will terminate, and all outstanding loans, together with all accrued and unpaid interest, must be repaid. Amounts not borrowed under the revolving facility will be subject to a commitment fee, to be paid in arrears on the last day of each fiscal quarter, ranging from 0.10% to 0.30% per annum depending on either the Company's credit rating at such time or the Company's leverage ratio as of the most recently ended fiscal quarter, whichever results in more favorable pricing to the Company. The Company may borrow funds under the 2014 Credit Facility in U.S. Dollars, Euros or in certain other agreed currencies, and borrowings will bear interest, at the Company’s option, at either: (i) a floating per annum base rate determined by reference to the highest of: (a) the administrative agent’s prime rate; (b) 0.50% per annum above the federal funds effective rate; and (c) reserve-adjusted LIBOR for an interest period of one month plus 1.00% , plus a margin of between 0.00% and 0.75% , or (ii) a reserve-adjusted fixed per annum rate based on LIBOR or EURIBOR, depending on the currency borrowed, plus a margin of between 1.00% and 1.75% . The applicable margin in each case is determined based on either Trimble’s credit rating at such time or Trimble’s leverage ratio as of its most recently ended fiscal quarter, whichever results in more favorable pricing to Trimble. Interest is payable on the last day of each fiscal quarter with respect to borrowings bearing interest at the base rate, or on the last day of an interest period, but at least every three months, with respect to borrowings bearing interest at LIBOR or EURIBOR rate. The 2014 Credit Facility contains various customary representations and warranties by the Company, which include customary use of materiality, material adverse effect and knowledge qualifiers. The 2014 Credit Facility also contains customary affirmative and negative covenants including, among other requirements, negative covenants that restrict the Company's ability to create liens and enter into sale and leaseback transactions, and that restrict its subsidiaries’ ability to incur indebtedness. Further, the 2014 Credit Facility contains financial covenants that require the maintenance of minimum interest coverage and maximum leverage ratios. Specifically, the Company must maintain as of the end of each fiscal quarter a ratio of (a) EBITDA (as defined in the 2014 Credit Facility) to (b) interest expense for the most recently ended period of four fiscal quarters of not less than 3.50 to 1.00. The Company must also maintain, at the end of each fiscal quarter, a ratio of (x) total indebtedness (as defined in the 2014 Credit Facility) to (y) EBITDA (as defined in the 2014 Credit Facility) for the most recently ended period of four fiscal quarters of not greater than 3.00 to 1.00; provided, that on the completion of a material acquisition, the Company may increase the ratio by 0.50 for the fiscal quarter during which such acquisition occurred and each of the three subsequent fiscal quarters. The Company was in compliance with these covenants at the end of fiscal 2015. The 2014 Credit Facility contains events of default that include, among others, non-payment of principal, interest or fees, breach of covenants, inaccuracy of representations and warranties, cross defaults to certain other indebtedness, bankruptcy and insolvency events, material judgments and events constituting a change of control. Upon the occurrence and during the continuance of an event of default, interest on the obligations will accrue at an increased rate in the case of an event of default arising from the nonpayment of principal and the lenders may accelerate the Company's obligations under the 2014 Credit Facility, except that acceleration will be automatic in the case of bankruptcy and insolvency events of default. The interest rate on the long-term debt outstanding under the 2014 Credit Facility was 1.46% and 1.42% at the end of fiscal 2015 and 2014, respectively. Uncommitted Facilities The Company also has two $75 million revolving credit facilities which are uncommitted (the "Uncommitted Facilities"). The Uncommitted Facilities may be called by the lenders at any time, have no covenants and no specified expiration date. The interest rate on the Uncommitted Facilities is 1.00% plus either LIBOR or the bank’s cost of funds or as otherwise agreed upon by the bank and the Company. The $118.0 million outstanding at the end of 2015 and the $57.0 million outstanding at the end of 2014 under the Uncommitted Facilities are classified as short-term in the Consolidated Balance Sheet. The weighted average interest rate on the Uncommitted Facilities was 1.37% at the end of fiscal 2015 and 1.15% at the end of fiscal 2014. Promissory Notes and Other Debt At the end of fiscal 2015 and 2014, the Company had promissory notes and other notes payable totaling approximately $1.2 million and $7.5 million , respectively, of which $0.9 million and $0.1 million , respectively, was classified as long-term in the Consolidated Balance Sheet. Debt Maturities At the end of fiscal 2015, the Company's debt maturities based on outstanding principal were as follows (in millions): Year Payable 2016 $ 118.3 2017 0.2 2018 0.2 2019 216.2 2020 0.1 Thereafter $ 400.2 Total $ 735.2

Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Operating Leases The Company’s principal facilities in the United States are leased under various cancelable and non-cancelable operating leases that expire at various dates through 2025. For tenant improvement allowances and rent holidays, Trimble records a deferred rent liability on the Consolidated Balance Sheets and amortizes the deferred rent over the terms of the leases as reductions to rent expense on the Consolidated Statements of Income. The estimated future minimum payments required under the Company’s operating lease commitments at the end of fiscal 2015 were as follows (in millions): 2016 $ 31.2 2017 25.2 2018 18.5 2019 15.1 2020 11.4 Thereafter 29.7 Total $ 131.1 Net rent expense under operating leases was $34.0 million in fiscal 2015, $34.1 million in fiscal 2014, and $32.2 million in fiscal 2013. At the end of fiscal 2015, the Company had unconditional purchase obligations of approximately $136.4 million . These unconditional purchase obligations primarily represent open non-cancelable purchase orders for material purchases with the Company’s vendors. Purchase obligations exclude agreements that are cancelable without penalty.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The Company determines fair value based on 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. Where available, fair value is based on observable market prices or parameters. Where observable prices or inputs are not available, valuation models are applied. Hierarchical levels, defined by the guidance on fair value measurements are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, and are as follows: Level I—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level II—Inputs (other than quoted prices included in Level I) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level III—Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are categorized in the tables below based upon the lowest level of significant input to the valuations. Fair Values at the end of Fiscal 2015 (In millions) Level I Level II Level III Total Assets Deferred compensation plan assets (1) $ 21.1 $ — $ — $ 21.1 Derivative assets (2) — 2.9 — 2.9 Contingent consideration assets (3) — — 7.0 7.0 Total $ 21.1 $ 2.9 $ 7.0 $ 31.0 Liabilities Deferred compensation plan liabilities (1) $ 21.1 $ — $ — $ 21.1 Derivative liabilities (2) — 2.1 — 2.1 Contingent consideration liabilities (4) — — 6.6 6.6 Total $ 21.1 $ 2.1 $ 6.6 $ 29.8 Fair Values at the end of Fiscal 2014 (In millions) Level I Level II Level III Total Assets Deferred compensation plan assets (1) $ 19.2 $ — $ — $ 19.2 Derivative assets (2) — 2.9 — 2.9 Contingent consideration assets (3) — — 8.3 8.3 Total $ 19.2 $ 2.9 $ 8.3 $ 30.4 Liabilities Deferred compensation plan liabilities (1) $ 19.2 $ — $ — $ 19.2 Derivative liabilities (2) — 1.4 — 1.4 Contingent consideration liabilities (4) — — 3.7 3.7 Total $ 19.2 $ 1.4 $ 3.7 $ 24.3 (1) The Company maintains a self-directed, non-qualified deferred compensation plan for certain executives and other highly compensated employees. The plan assets and liabilities are invested in actively traded mutual funds and individual stocks valued using observable quoted prices in active markets. Deferred compensation plan assets and liabilities are included in Other non-current assets and Other non-current liabilities, respectively, on the Company's Consolidated Balance Sheets. (2) Derivative assets and liabilities primarily represent forward currency exchange contracts. The Company typically enters into these contracts to minimize the short-term impact of foreign currency exchange rates on certain trade and inter-company receivables and payables. Derivative assets and liabilities are included in Other current assets and Other current liabilities on the Company's Consolidated Balance Sheets. (3) Contingent consideration assets represents arrangements for buyers to pay the Company for certain businesses that it has divested. The fair value is determined based on the Company's expectations of future receipts. The minimum amount to be received under these arrangements is $3.5 million . Contingent consideration assets are included in Other non-current assets on the Company's Consolidated Balance Sheets. (4) Contingent consideration liabilities represents arrangements to pay the former owners of certain companies that Trimble acquired. The undiscounted maximum payment under the arrangements is $21.4 million at the end of fiscal 2015, based on future revenues, gross margins and other milestones. Contingent consideration liabilities is included on Other current liabilities and Other non-current liabilities on the Company's Consolidated Balance Sheets.

The fair value of the Notes was determined based on observable market prices in less active markets and is categorized accordingly as Level II in the fair value hierarchy. The fair value of the bank borrowings and promissory notes has been calculated using an estimate of the interest rate the Company would have had to pay on the issuance of notes with a similar maturity and discounting the cash flows at that rate, and is categorized as Level II in the fair value hierarchy. The fair values do not give an indication of the amount that the Company would currently have to pay to extinguish any of this debt.

These included a change in geographic mix of pretax income, which was partially offset by tax benefits resulting from the closing of a foreign tax audit, valuation allowance releases and an increase in federal research and development credit. During the fourth quarter of fiscal 2015, due to legislation, the federal research and development credit was made permanent. The Company recorded a tax benefit in the fourth quarter of fiscal 2015. The effective tax rate in fiscal 2014 increased compared to 2013 in part due to a change in geographic mix of pretax income and recognition of federal research and development credit for 2014, instead of two years as was the case in fiscal 2013. During the fourth quarter of fiscal 2014, due to legislation, the federal research and development credit was extended through December 31, 2014. As a result, the Company recorded a tax benefit in the fourth quarter of fiscal 2014. Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The significant components of the Company’s deferred tax assets and liabilities are as follows: At the End of Fiscal Year 2015 2014 (In millions) Deferred tax liabilities: Purchased intangibles $ 122.6 $ 143.3 Depreciation and amortization 11.0 11.3 US residual tax on foreign earnings 12.2 12.3 Other — 0.3 Total deferred tax liabilities 145.8 167.2 Deferred tax assets: Inventory valuation differences 11.5 9.8 Expenses not currently deductible 26.2 26.2 US federal tax credit carryforwards 0.6 0.4 Deferred revenue 6.6 4.5 US state tax credit carryforwards 16.4 15.7 Accrued warranty 3.4 3.8 US federal net operating loss carryforwards 5.5 7.9 Foreign net operating loss carryforwards 41.7 29.7 Stock-based compensation 29.6 21.8 Other 9.0 5.3 Total deferred tax assets 150.5 125.1 Valuation allowance (34.9 ) (29.3 ) Total deferred tax assets 115.6 95.8 Total net deferred tax liabilities $ (30.2 ) $ (71.4 ) Reported as: Current deferred income tax assets $ — $ 45.6 Non-current deferred income tax assets 21.5 5.0 Current deferred income tax liabilities — (0.9 ) Non-current deferred income tax liabilities (51.7 ) (121.1 ) Net deferred tax liabilities $ (30.2 ) $ (71.4 ) In the fourth quarter of 2015, the Company adopted new accounting guidance for balance sheet classification of deferred taxes, which requires that all deferred income tax assets and liabilities be classified as non-current in the balance sheet. The guidance was adopted on a prospective basis and, therefore, prior periods were not retrospectively adjusted. At the end of fiscal 2015, the Company has federal and foreign net operating loss carryforwards, or NOLs, of approximately $18.5 million and $208.2 million , respectively. The federal NOLs expire beginning year 2021 . There is, generally, no expiration for the foreign NOLs. Utilization of the Company’s federal and state NOLs are subject to annual limitations in accordance with the applicable tax code. The Company has determined that it is more likely than not that the Company will not realize a portion of the foreign NOLs and, accordingly, a valuation allowance has been established for such amount. The Company has Federal and California research and development credit carryforwards of approximately $0.9 million and $18.6 million , respectively. The federal tax credit carryforwards will expire beginning 2030 . The California research tax credits have indefinite carryforward period. The Company believes that it is more likely than not that the Company will not realize a portion of the California research and development credit carryforwards and, accordingly, a valuation allowance has been established for such amount. At the end of fiscal 2015, the Company’s foreign subsidiaries had approximately $776.2 million of accumulated undistributed earnings that are intended to be indefinitely reinvested outside the U.S. and, accordingly, no provision for federal, state income taxes have been provided thereon. If such earnings were to be distributed in the form of dividends or otherwise, the Company would have to recognize additional tax liability of approximately $237.1 million . The total amount of the unrecognized tax benefits at the end of fiscal 2015 was $59.0 million . A reconciliation of unrecognized tax benefit is as follows: At the End of Fiscal Year 2015 2014 2013 (In millions) Beginning gross balance $ 51.4 $ 44.1 $ 32.2 Increase related to prior years' tax positions 6.0 0.8 1.8 Increase related to current year tax positions 6.2 7.5 12.0 Lapse of statute of limitations (1.5 ) (1.0 ) (1.9 ) Settlement with taxing authorities (3.1 ) — — Ending gross balance $ 59.0 $ 51.4 $ 44.1 The Company's total unrecognized tax benefits that, if recognized, would affect its effective tax rate were $52.7 million and $45.6 million at the end of fiscal 2015 and 2014, respectively. The Company and its subsidiaries are subject to U.S. federal, state, and foreign income taxes. The Company has substantially concluded all U.S. federal income tax audits for years through 2009. State income tax matters have been concluded for years through 2008 and non-U.S. income tax matters have been concluded for years through 2004. The Company is currently in various stages of multiple year examinations by federal, state, and foreign (multiple jurisdictions) taxing authorities. While the Company generally believes it is more likely than not that its tax positions will be sustained, it is reasonably possible that future obligations related to these matters could arise. The Company believes that its reserves are adequate to cover any potential assessments that may result from the examinations and negotiations. Although the timing of resolution and/or closure for these audits is highly uncertain, the Company does not believe that the unrecognized tax benefits would materially change in the next twelve months. In the first quarter of fiscal 2015, the Company received a Notice of Proposed Adjustment from the IRS for the fiscal years 2010 and 2011. The proposed adjustments primarily relate to the valuations of intercompany transfers of acquired intellectual property. The assessments of tax, interest and penalties for the years in question total $67.0 million . The Company does not agree with the IRS position and has filed a protest with the IRS Appeals Office in April 2015. In the fourth quarter of fiscal 2015, an IRS Appeals conference date was set for March 2016. No payments have been made on the assessment. The Company intends to vigorously contest the IRS position. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company’s liability for unrecognized tax benefits including interest and penalties was recorded in Other non-current liabilities in the accompanying Consolidated Balance Sheets. At the end of fiscal 2015 and 2014, the Company had accrued $6.7 million and $4.7 million , respectively, for payment of interest and penalties.

Employee Stock Benefit Plans	EMPLOYEE STOCK BENEFIT PLANS The Company’s stock benefit plans include the employee stock purchase plan and stock plans adopted in 2002, 1993, 1992, 1990, as well as one stock plan assumed through an acquisition in 2007. Other than the employee stock purchase plan and the 2002 and 1992 stock plans described below, the other plans have no shares available for future grant. Plans Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan (“Purchase Plan”) under which an aggregate of 39.1 million shares of Common Stock have been approved for issuance to eligible employees as approved by the shareholders to date. The plan permits eligible employees to purchase Common Stock through payroll deductions at 85% of the lower of the fair market value of the Common Stock at the beginning or at the end of each offering period, which is generally six months. Rights to purchase shares are granted during the first and third quarter of each fiscal year. The Purchase Plan terminates on September 30, 2018. In fiscal 2015 , 2014 and 2013 , 1.0 million , 0.7 million , and 0.6 million shares were issued, respectively, representing $18.1 million , $16.4 million and $13.5 million in cash received for the issuance of stock under the Purchase Plan. At the end of fiscal 2015 , the number of shares reserved for future purchases by eligible employees was 10.9 million . 2002 Stock Plan Trimble’s 2002 Stock Plan (“2002 Plan”), provides for the granting of incentive and non-statutory stock options and restricted stock units ("RSUs") for up to 62.6 million shares plus any shares currently reserved but unissued to employees, consultants, and directors of Trimble. Both incentive and non-statutory stock options may be granted at exercise prices that are not less than 100% of the fair market value of Common Stock on the date of grant. Employee stock options under the 2002 plan generally vest over four years with biennial, annual, or monthly vesting, and expire seven years from the date of grant. RSUs are converted into shares of Trimble common stock upon vesting on a one-for-one basis, except those with market-based vesting conditions in which the number of shares that may be issued ranges from 0% to 200% of the units granted. RSUs granted to employees generally vest over three years. RSUs granted to non-employee directors generally vest after one year. Grants of RSUs assumes the maximum number of shares will be issued and decreases the plan reserves by 1.69 X that amount and any forfeitures of these awards due to their not vesting would increase the plan reserve by the same measure. 1992 Employee Stock Bonus Plan At the end of fiscal 2015 , there were no options outstanding to purchase shares under the 1992 Employee Stock Bonus Plan (“Bonus Plan”) and 1,606 shares were available for future grant under the Bonus Plan. Stock Option and Restricted Stock Unit Activity The following table summarizes the Company’s stock option and restricted stock unit activity during fiscal 2015 : Stock Options Outstanding Restricted Stock Units Outstanding Shares Available for Grant Options Weighted average Restricted Weighted Average (In millions, except for per share data) Outstanding at the beginning of year 14.4 13.1 $ 21.23 3.1 $ 28.14 Granted (4.3 ) 0.1 $ 25.08 2.1 $ 24.84 Option exercised — (1.3 ) $ 12.35 — $ — Shares released, net — — $ — (0.7 ) $ 24.86 Cancelled and Forfeited 0.7 (0.3 ) $ 25.58 (0.2 ) $ 27.78 Outstanding at the end of year 10.8 11.6 $ 22.15 4.3 $ 26.98 The following table summarizes information about stock options outstanding as of fiscal 2015 year end: Number Of Shares (in millions) Weighted- Average Exercise Price per Share Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in millions) Vested and expected to vest 11.4 $ 22.08 3.02 $ 24.3 Options exercisable 8.6 $ 20.42 2.49 $ 24.0 The intrinsic value of options vested and expected to vest and exercisable is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of the end of fiscal 2015 . The total intrinsic value of options exercised during fiscal 2015 , 2014 and 2013 was $13.9 million , $61.3 million , and $55.5 million , respectively, and is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of the exercise date. The following table summarizes information about restricted stock units outstanding as of fiscal 2015 : Number Weighted- (in years) Aggregate Vested and expected to vest 3.8 1.77 $ 82.5 The fair value of restricted stock units vested and expected to vest as of fiscal 2015 is calculated based on the fair value of the Company’s common stock as of the end of fiscal 2015 . Stock-Based Compensation Expense The following table summarizes stock-based compensation expense included in the Consolidated Statements of Income. Fiscal Years 2015 2014 2013 (In millions) Cost of sales $ 3.9 $ 3.2 $ 2.6 Research and development 8.7 6.8 5.1 Sales and marketing 9.1 7.6 7.3 General and administrative 28.4 25.8 21.5 Total operating expenses 46.2 40.2 33.9 Total stock-based compensation expense $ 50.1 $ 43.4 $ 36.5 Fair Value of Share Purchase Rights The fair value of the share purchase rights granted under the Purchase Plan are valued using the Black-Scholes option pricing model with the following weighted-average assumptions: Fiscal Years 2015 2014 2013 Expected life of purchase 0.5 years 0.5 years 0.5 years Expected stock price volatility 31.3 % 30.5 % 31.5 % Risk free interest rate 0.08 % 0.07 % 0.12 % Expected dividend yield — — — Expected Life of Purchase— The Company’s expected life of the purchase is based on the term of the offering period of the purchase plan. Expected Stock Price Volatility —The Company’s computation of expected volatility is based on implied volatilities from traded options on the Company’s stock. The Company used implied volatility because it is representative of future stock price trends during the purchase period. Expected Risk Free Interest Rate —The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the purchase period. Expected Dividend Yield —The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. The weighted average grant-date fair value per share of stock purchase rights granted under the Employee Stock Purchase Plan during fiscal years 2015 , 2014 and 2013 was $5.24 , $8.32 and $8.05 per share, respectively. Fair value of Stock Options The fair value of stock compensation is valued as of the grant date using a binomial valuation model. The binomial model takes into account variables such as volatility, dividend yield rate, and risk free interest rate. In addition, the binomial model incorporates actual option-pricing behavior and changes in volatility over the option’s contractual term. For options granted during fiscal 2015, 2014 and 2013, the following weighted-average assumptions were used: Fiscal Years 2015 2014 2013 Expected life of options 3.9 years 4.0 years 3.9 years Expected stock price volatility 36 % 35 % 35 % Risk free interest rate 1.26 % 1.29 % 0.69 % Expected dividend yield — — — Expected Life of Options —The Company’s expected life represents the period that the Company’s stock options are expected to be outstanding and was determined based on historical experience of similar stock options with consideration for the contractual terms of the stock options, vesting schedules and expectations of future employee behavior. Expected Stock Price Volatility —The Company’s computation of expected volatility is based on a combination of implied volatilities from traded options on the Company’s stock and historical volatility, commensurate with the expected life of the stock options. Expected Risk Free Interest Rate —The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected life of the option. Expected Dividend Yield —The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. The weighted average grant-date fair value per share of stock options granted during fiscal years 2015 , 2014 and 2013 was $7.36 , $9.07 , and $7.90 , respectively. The fair value of all stock options vested during fiscal years 2015, 2014 and 2013 was $18.3 million , $20.5 million and $20.3 million , respectively. Fair value of Restricted Stock Units The fair value of restricted stock units is valued as of the grant date using the fair value of Trimble’s common stock. The weighted average grant-date fair value per share of RSUs granted during fiscal years 2015 , 2014 and 2013 was $23.22 , $30.18 , and $28.17 per share, respectively. The fair value of all restricted stock units vested during fiscal years 2015, 2014 and 2013 was $16.3 million , $3.9 million and $10.0 million , respectively. Fair Value of Market-Based Restricted Stock Units Restricted stock units with market-based vesting conditions vest based on the achievement of the Company’s relative total shareholder return (TSR) of its common stock as compared to the TSR of the constituents of the S&P 500 at the start of the performance period. The fair value of restricted stock units with market-based vesting conditions is valued as of the grant date using a Monte Carlo simulation, using the following weighted-average assumptions: Fiscal Years 2015 Expected life of options 2.6 years Expected stock price volatility 30.9 % Risk free interest rate 0.9 % Expected dividend yield — The weighted average grant-date fair value of the restricted stock units with market-based vesting conditions granted during fiscal 2015 was $31.60 per share. Unrecognized Stock-Based Compensation At the end of fiscal 2015, total unamortized stock-based compensation expense was $94.6 million , with a weighted-average recognition period of 2.1 years.

Statement of Stockholders' Equity [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	COMMON STOCK REPURCHASE In August 2014, the Company's Board of Directors approved a stock repurchase program (2014 Stock Repurchase Program), authorizing the Company to repurchase up to $300.0 million of Trimble’s common stock, replacing a stock repurchase program which had been in place since 2011. In August 2015, the Company’s Board of Directors approved a stock repurchase program (2015 Stock Repurchase Program), authorizing the Company to repurchase up to $400.0 million of Trimble’s common stock, replacing the 2014 Stock Repurchase Program. During fiscal 2015, the Company repurchased approximately 7.5 million shares of common stock in open market purchases, at an average price of $21.29 per share, for a total of $159.4 million . This total includes $75.1 million and $84.3 million of open market purchases completed under the 2015 and 2014 Stock Repurchase Programs, respectively. As part of the 2015 Stock Repurchase Program, in September 2015, the Company entered into an accelerated share repurchase agreement, or ASR, with an investment bank for $75.0 million . The ASR was completed in December 2015 and resulted in the aggregate repurchase of approximately 3.7 million shares of common stock with a volume weighted average price of $20.11 per share. During fiscal 2014, under the provisions of both the 2014 and 2011 Stock Repurchase Programs, the Company repurchased approximately 3.2 million shares of common stock in open market purchases at an average price of $30.22 per share, for a total of $97.8 million . No shares of common stock were repurchased during fiscal 2013. Stock repurchases are reflected as a decrease to common stock based on the average book value per share for all outstanding shares calculated at the time of each individual repurchase transaction. The excess of the purchase price over this average for each repurchase was charged to retained earnings. As a result of the 2015 repurchases, retained earnings was reduced by $180.3 million in fiscal 2015. Common stock repurchases under the program were recorded based upon the trade date for accounting purposes. All common shares repurchased under this program have been canceled. At the end of fiscal 2015, the 2015 Stock Repurchase Program had remaining authorized funds of $249.9 million . Under the share repurchase program, the Company may repurchase shares from time to time in open market transactions, privately negotiated transactions, accelerated share buyback programs, tender offers, or by other means. The timing and amount of repurchase transactions will be determined by the Company’s management based on its evaluation of market conditions, share price, legal requirements and other factors. The program may be suspended, modified or discontinued at any time without prior notice.

Litigation	LITIGATION On August 9, 2013, Harbinger Capital Partners, LLC and additional plaintiffs (“Harbinger Plaintiffs”) filed a lawsuit against Deere & Co., Garmin, the Company and two other defendants in the U.S. District Court in Manhattan in connection with Plaintiffs’ investment in LightSquared. The Harbinger Plaintiffs alleged, among other things, fraud and negligent misrepresentation, claiming that the defendants were aware of material facts that caused the Federal Communications Commission to take adverse action against LightSquared and failed to disclose those facts prior to Plaintiffs’ investment in LightSquared, and sought $1.9 billion in damages from the defendants. On November 1, 2013, LightSquared, Inc. and several related parties (“LightSquared Plaintiffs”) filed suit against the same defendants, asserting similar state law claims to those made in the Harbinger lawsuit, as well as additional claims, including breach of contract. On February 5, 2015, the U.S. District Court dismissed all claims brought by the Harbinger Plaintiffs and the majority of those brought by the LightSquared Plaintiffs. On February 11, 2015, the Harbinger Plaintiffs filed a notice of appeal of the District Court’s dismissal of their claims. The District Court’s dismissal of claims of the Harbinger Plaintiffs was affirmed by the Second Circuit Court of Appeals on December 7, 2015. Incident to approval of its bankruptcy reorganization plan effective December 7, 2015, LightSquared Inc.’s successor under the bankruptcy reorganization plan acquired the claims of the Harbinger Plaintiffs. On December 14, 2015, the LightSquared Plaintiffs (as reorganized) dismissed all claims against the Company without prejudice pursuant to an initial agreement with the Company. On February 3, 2016, the LightSquared Plaintiffs (as reorganized) and the Company entered into a settlement agreement which includes mutual releases of all claims between the parties, and which provides for the dismissal of all claims of the LightSquared Plaintiffs (as reorganized) with prejudice. Under the settlement agreement, the LightSquared Plaintiffs (as reorganized) further agreed to take no further action to preserve or prosecute the claims of the Harbinger Plaintiffs. On September 2, 2011 Research Data Services, LLC filed a lawsuit in the Superior Court for the State of Alaska in Anchorage against Trimble Navigation Limited, Cabela’s Incorporated, AT&T Mobility and Alascom, Inc., alleging breach of contract, breach of fiduciary duty, interference with contract, promissory estoppel, fraud, and negligent misrepresentation. The case was tried in front of a jury in Alaska beginning on September 9, 2014. On September 26, 2014, the jury returned a verdict in favor of the plaintiff and awarded the plaintiff damages of $51.3 million . On January 29, 2015, the court granted our Motion for Judgment Notwithstanding the Verdict, and on March 18, 2015, the Court awarded the Company a portion of its incurred attorneys’ fees and costs, and entered judgment in the Company’s favor in the amount of $0.6 million . The judgment also provides that Plaintiff take nothing on its claims. On April 17, 2015, Plaintiff filed a Notice of Appeal to the Alaska Supreme Court. The parties have completed all appellate briefing, and the matter is scheduled for oral argument before the Alaska Supreme Court. On March 12, 2015, Rachel Thompson filed a putative class action complaint in California Superior Court against the Company, the members of its Board of Directors, and JP Morgan Chase Bank. The suit alleges that the Company’s Board of Directors breached their fiduciary obligations to the Company’s shareholders by entering into a credit agreement with JP Morgan Chase Bank that contains certain change of control provisions that plaintiff contends are disadvantageous to shareholders. The complaint seeks declaratory relief, injunctive relief, and costs of the action but does not seek monetary damages. The parties have reached a proposed settlement, which would modify one provision of the credit agreement and permit the named plaintiff to seek recovery of attorney’s fees. By order filed February 1, 2016, the Court granted preliminary approval of the proposed settlement, ordered that notice be provided to shareholders, and scheduled a hearing to consider any objections to the settlement. From time to time, the Company is also involved in litigation arising out of the ordinary course of our business. There are no other material legal proceedings, other than ordinary routine litigation incidental to the business, to which the Company or any of its subsidiaries is a party or of which any of the Company's or its subsidiaries' property is subject.

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Error Corrections [Text Block]	REVISIONS TO PREVIOUSLY REPORTED FINANCIAL INFORMATION In the third quarter of fiscal 2015, the Company identified an error in its previously reported financial statements with regard to a portion of its goodwill balance arising from deferred tax liabilities in foreign jurisdictions that had not been properly translated to U.S. dollars. As a result, both goodwill and the cumulative translation adjustment included in Accumulated other comprehensive loss on the Consolidated Balance Sheets were overstated and the resulting foreign currency translation adjustment component of Other comprehensive income was incorrect. There was no impact on Net Income or Cash Flows. The Company evaluated the impact of the error, both quantitatively and qualitatively, and concluded that the differences were not material individually or in the aggregate to any of the prior reporting periods. The impact has no effect on Net Income or Cash Flows, but in light of the significance of the cumulative amount of the error on comprehensive income to the third quarter and full year 2015, the Company has revised previously issued financial information for periods contained in this Annual Report on Form 10-K to correct for the foreign currency translation figures. The following table presents the impact of the adjustment to the Condensed Consolidated Balance Sheet line items as of 2014 fiscal year end (in millions): As of Fiscal Year End 2014 As previously As Consolidated Balance Sheet Data: Reported (1) Adjustment Revised Goodwill $ 2,101.2 $ (15.4 ) $ 2,085.8 Total assets 3,871.3 (15.4 ) 3,855.9 Accumulated other comprehensive loss (61.3 ) (15.4 ) (76.7 ) Total Trimble Navigation Limited shareholders' equity 2,357.0 (15.4 ) 2,341.6 Total equity 2,368.8 (15.4 ) 2,353.4 Total liabilities and equity 3,871.3 (15.4 ) 3,855.9 (1) Total assets and total liabilities and equity as previously reported have been adjusted to reflect the reclassification of debt issuance costs.

Accounting Policies (Policy)

Accounting Policies (Policy)	12 Months Ended
	Jan. 01, 2016
Accounting Policies [Abstract]
Use Of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for allowances for doubtful accounts, sales returns reserve, allowances for inventory valuation, warranty costs, investments, goodwill impairment, intangibles impairment, purchased intangibles, stock-based compensation, and income taxes among others. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the company in the future, actual results may differ materially from management’s estimates.
Basis Of Presentation	Basis of Presentation The Company has a 52-53 week fiscal year, ending on the Friday nearest to December 31. Fiscal 2015 and 2014 were both 52-week years, and ended on January 1, 2016 and January 2, 2015, respectively. Fiscal 2013 was a 53-week year and ended on January 3, 2014. Unless otherwise stated, all dates refer to the Company’s fiscal year. These Consolidated Financial Statements include the results of the Company and its consolidated subsidiaries. Inter-company accounts and transactions have been eliminated. Noncontrolling interests represent the noncontrolling shareholders’ proportionate share of the net assets and results of operations of the Company’s consolidated subsidiaries. The Company has presented revenue and cost of sales separately for products, service and subscriptions. Product revenue includes hardware, software licenses, parts and accessories; service revenue includes maintenance and support for hardware and software products, training and professional services; subscription revenue includes software as a service (SaaS).
Reclassification, Policy	Historically, the Company allocated stock-based compensation to each segment. Beginning with the first quarter of fiscal 2015, the Company changed its methodology for allocating stock-based compensation to its segments. Stock-based compensation is shown in the aggregate within unallocated corporate expense and is not reflected in the segment results, which is consistent with the way the Chief Operating Decision Maker (CODM) evaluates each of the segment's performance and allocates resources. The Company has adjusted the presentation of previously reported segment information to conform to the current year methodology within Note 7.
Comparability of Prior Year Financial Data, Policy	In the third quarter of fiscal 2015, the Company identified an error in its previously reported financial statements with regard to a portion of its goodwill balance arising from deferred tax liabilities in foreign jurisdictions that had not been properly translated to U.S. dollars. As a result, both goodwill and the cumulative translation adjustment included in Accumulated other comprehensive loss on the Consolidated Balance Sheets were overstated and the resulting foreign currency translation adjustment component of Other comprehensive loss was incorrect. There was no impact on Net Income or Cash Flows. The Company evaluated the impact of the error, both quantitatively and qualitatively, and concluded that the differences were not material individually or in the aggregate to any of the prior reporting periods. The impact has no effect on Net Income or Cash Flows, but in light of the significance of the cumulative amount of the error on comprehensive income on the full year 2015, the Company has revised previously issued financial information for periods contained in this Annual Report on Form 10-K to correct for the foreign currency translation figures. Interim periods not presented herein will be revised, as applicable, when they are included in future filings. See Note 17 of the Notes to Consolidated Financial Statements for further information.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in local currencies are translated to U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive income, net of tax in accumulated other comprehensive loss within the shareholders’ equity section of the Consolidated Balance Sheets. Income and expense accounts are translated at average monthly exchange rates during the year.
Derivative Financial Instruments	Derivative Financial Instruments The Company enters into foreign exchange forward contracts to minimize the short-term impact of foreign currency fluctuations on cash, certain trade and inter-company receivables and payables, primarily denominated in Australian, Canadian, Singapore and New Zealand Dollars, Japanese Yen, Chinese Yuan, Indian Rupee, Brazilian Real, South African Rand, Swedish Krona, Swiss Franc, Euro and British pound. These contracts reduce the exposure to fluctuations in exchange rate movements as the gains and losses associated with foreign currency balances are generally offset with the gains and losses on the forward contracts. These instruments are marked to market through earnings every period and generally range from one to two months in original maturity. The Company occasionally enters into foreign exchange forward contracts to hedge the purchase price of some of its larger business acquisitions. The Company does not enter into foreign exchange forward contracts for trading purposes. As of the fiscal years ended 2015 and 2014, there were no derivative financial instruments outstanding that were accounted for as hedges.
Cash And Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all cash and highly liquid investments with insignificant interest rate risk and maturities of three months or less at the date of purchase. The carrying amount of cash and cash equivalents approximates fair value because of the short maturity of those instruments. The fair value of cash and cash equivalents is based on quoted prices in active markets for identical assets or liabilities, and is categorized as Level I in the fair value hierarchy. The fair value of the Notes was determined based on observable market prices in less active markets and is categorized accordingly as Level II in the fair value hierarchy. The fair value of the bank borrowings and promissory notes has been calculated using an estimate of the interest rate the Company would have had to pay on the issuance of notes with a similar maturity and discounting the cash flows at that rate, and is categorized as Level II in the fair value hierarchy. The fair values do not give an indication of the amount that the Company would currently have to pay to extinguish any of this debt.
Concentration Of Risk	Concentration of Risk Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and therefore bear minimal credit risk. The Company is also exposed to credit risk in the Company’s trade receivables, which are derived from sales to end-user customers in diversified industries as well as various resellers. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary but generally does not require collateral. With Flextronics Corporation International as an exclusive manufacturing partner for many of its products, the Company is dependent upon a sole supplier for the manufacture of these products. In addition, the Company relies on sole suppliers for a number of its critical components.
Allowance For Doubtful Accounts	Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company evaluates the ongoing collectibility of its trade accounts receivable based on a number of factors such as age of the accounts receivable balances, credit quality, historical experience, and current economic conditions that may affect a customer’s ability to pay. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations to the Company, a specific allowance for bad debts is estimated and recorded which reduces the recognized receivable to the estimated amount that the Company believes will ultimately be collected. In addition to specific customer identification of potential bad debts, bad debt charges are recorded based on the Company’s recent past loss history and an overall assessment of past due trade accounts receivable amounts outstanding.
Inventories	Inventories Inventories are stated at the lower of cost or market. Adjustments are also made to reduce the cost of inventory for estimated excess or obsolete balances. Factors influencing these adjustments include declines in demand which impact inventory purchasing forecasts, technological changes, product life cycle and development plans, component cost trends, product pricing, physical deterioration and quality issues.
Property And Equipment, Net	Property and Equipment, Net Property and equipment, net is stated at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the shorter of the estimated useful lives or the lease terms when applicable. Useful lives generally include a range from four to six years for machinery and equipment, five to seven years for furniture and fixtures, two to five years for computer equipment and software, 39 years for buildings, and the life of the lease for leasehold improvements. The Company capitalizes eligible costs to acquire or develop internal-use software that are incurred subsequent to the preliminary project stage. Capitalized costs related to internal-use software are amortized using the straight-line method over the estimated useful lives of the assets, which range generally from two to five years. The costs of repairs and maintenance are expensed when incurred, while expenditures for refurbishments and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Depreciation expense was $36.7 million in fiscal 2015 , $33.1 million in fiscal 2014 and $26.7 million in fiscal 2013 .
Business Combinations	Business Combinations The Company allocates the fair value of purchase consideration to the assets acquired, liabilities assumed, and non-controlling interests in the acquiree based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired, liabilities assumed and non-controlling interests in the acquiree is recorded as goodwill. When determining the fair values of assets acquired, liabilities assumed, and non-controlling interests in the acquiree, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing intangible assets include, but are not limited to, expected future cash flows, which includes consideration of future growth rates and margins, customer attrition rates, future changes in technology and brand awareness, loyalty and position, and discount rates. Fair value estimates are based on the assumptions management believes a market participant would use in pricing the asset or liability. Amounts recorded in a business combination may change during the measurement period, which is a period not to exceed one year from the date of acquisition, as additional information about conditions existing at the acquisition date becomes available. The Company determined the total consideration paid for each of its acquisitions as well as the fair value of the assets acquired and liabilities assumed as of the date of each acquisition. For certain acquisitions completed in fiscal 2015, the fair value of the assets acquired and liabilities assumed are preliminary and may be adjusted as the Company obtains additional information, primarily related to adjustments for the true up of acquired net working capital in accordance with certain purchase agreements, and estimated values of certain net tangible assets and liabilities including tax balances, pending the completion of final studies and analyses. If there are adjustments made for these items the fair value of intangible assets and goodwill could be impacted. Thus the provisional measurements of fair value set forth below are subject to change. Such changes could be significant. The Company expects to finalize the valuation of the net tangible and intangible assets as soon as practicable, but not later than one -year from the acquisition date. The fair value of identifiable assets acquired and liabilities assumed were determined under the acquisition method of accounting for business combinations. The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. The fair value of intangible assets acquired is generally determined based on a discounted cash flow analysis. Acquisition costs of $12.0 million , $13.4 million and $13.5 million in fiscal 2015 , 2014 and 2013 , respectively, were expensed as incurred and were included in General and administrative expenses in the Consolidated Statements of Income.
Goodwill And Purchased Intangible Assets	Goodwill and Purchased Intangible Assets Goodwill represents the excess of the purchase consideration over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets acquired individually, with a group of other assets, or in a business combination are recorded at fair value. Identifiable intangible assets are comprised of distribution channels and distribution rights, patents, licenses, technology, acquired backlog, trademarks and in-process research and development. Identifiable intangible assets are being amortized over the period of estimated benefit using the straight-line method, reflecting the pattern of economic benefits associated with these assets, and have estimated useful lives ranging from one month to twelve years with a weighted average useful life of 6.2 years. Goodwill is not subject to amortization, but is subject to at least an annual assessment for impairment, applying a fair-value based test.
Impairment Of Goodwill, Intangible Assets And Other Long-Lived Assets	Impairment of Goodwill, Intangible Assets and Other Long-Lived Assets The Company evaluates goodwill, at a minimum, on an annual basis and whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. The Company performs its annual goodwill impairment testing in the fourth fiscal quarter of each year based on the values on the first day of that quarter. For the Company's annual goodwill impairment test in the fourth quarter of fiscal 2015 goodwill was reviewed for impairment utilizing a quantitative two-step process. In the first step of this test, goodwill is tested for impairment at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated using a discounted cash flow approach. If the carrying amount of the reporting unit exceeds its fair value, a second step is performed to measure the amount of impairment loss, if any. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting unit’s goodwill, the difference is recognized as an impairment loss. When the Company performs a quantitative assessment of goodwill impairment, the determination of fair value of a reporting unit involves the use of significant estimates and assumptions. The discounted cash flows are based upon, among other things, assumptions about expected future operating performance using risk-adjusted discount rates. Actual future results may differ from those estimates. As of the first day of the fourth quarter of fiscal 2015, the fair value for our reporting units ranged from 131% to approximately 701% of carrying amounts, therefore goodwill was not impaired and no further testing was required. For certain earlier stage reporting units, due to the smaller magnitude of the carrying value and fair value of each respective reporting unit, the margins by which the fair value exceeded the carrying value on an absolute dollar basis were relatively small. Depreciation and amortization of the Company’s intangible assets and other long-lived assets is provided using the straight-line method over their estimated useful lives, reflecting the pattern of economic benefits associated with these assets. Changes in circumstances such as technological advances, changes to the Company’s business model, or changes in the capital strategy could result in the actual useful lives differing from initial estimates. In cases where the Company determines that the useful life of an asset should be revised, the Company will depreciate the net book value in excess of the estimated residual value over its revised remaining useful life. These assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance and these estimates may differ from actual future cash flows. The assets evaluated for impairment are grouped with other assets to the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. If the sum of the projected undiscounted cash flows (excluding interest) is less than the carrying value of the assets, the assets will be written down to the estimated fair value.
Warranty	Warranty The Company accrues for warranty costs as part of its cost of sales based on associated material product costs, technical support labor costs, and costs incurred by third parties performing work on the Company’s behalf. The Company’s expected future cost is primarily estimated based upon historical trends in the volume of product returns within the warranty period and the cost to repair or replace the equipment. When products sold include warranty provisions, they are covered by a warranty for periods ranging generally from 1 year to 2 years. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers, its warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage, or service delivery costs differ from the estimates, revisions to the estimated warranty accrual and related costs may be required. Changes in the Company’s product warranty liability during the fiscal years ended 2015 and 2014 are as follows: At the End of Fiscal Year 2015 2014 (In millions) Beginning balance $ 20.6 $ 17.8 Acquired warranties 0.1 — Accruals for warranties issued 16.6 22.8 Changes in estimates 4.8 2.6 Warranty settlements (in cash or in kind) (23.6 ) (22.6 ) Ending Balance $ 18.5 $ 20.6
Guarantees, Including Indirect Guarantees Of Indebtedness Of Others	Guarantees, Including Indirect Guarantees of Indebtedness of Others In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, lessors, and parties to other transactions with the Company. For example, the Company has agreed to hold the other party harmless against losses arising from a breach of representations or covenants, or out of intellectual property infringement or other claims made by certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents. It is not possible to determine the maximum potential exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not been material and no liabilities have been recorded on the Consolidated Balance Sheets at the end of fiscal 2015 and 2014 .
Revenue Recognition	Revenue Recognition The Company recognizes revenue when it is realized or realizable and earned. The Company considers revenue realized or realizable and earned when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is reasonably assured. In instances where final acceptance of the product is specified by the customer or is uncertain, revenue is deferred until all acceptance criteria have been met. Contracts and/or customer purchase orders are used to determine the existence of an arrangement. Shipping documents and customer acceptance, when applicable, are used to verify delivery. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. The Company assesses collectibility based primarily on the creditworthiness of the customer as determined by credit checks and analyses, as well as the customer’s payment history. Revenue for orders is not recognized until the product is shipped and title has transferred to the buyer. The Company bears all costs and risks of loss or damage to the goods up to that point. The Company’s shipment terms for U.S. orders and international orders fulfilled from the Company’s European distribution center typically provide that title passes to the buyer upon delivery of the goods to the carrier named by the buyer at the named place or point. If no precise point is indicated by the buyer, delivery is deemed to occur when the carrier takes the goods into its charge from the place determined by the Company. Other shipment terms may provide that title passes to the buyer upon delivery of the goods to the buyer. Shipping and handling costs are included in Cost of sales. Revenue from sales to distributors and dealers is recognized upon shipment, assuming all other criteria for revenue recognition have been met. Distributors and dealers do not have a right of return. Revenue from purchased extended warranty and post contract support (PCS) agreements is deferred and recognized ratably over the term of the warranty or support period. Revenue from the Company's subscription services related to its hardware and software applications is recognized ratably over the term of the subscription service period beginning on the date that service is made available to the customer, assuming all revenue recognition criteria have been met. The Company presents revenue net of sales taxes and any similar assessments. The Company’s software arrangements generally consist of a perpetual license fee and PCS. The Company generally has established vendor-specific objective evidence (VSOE) of fair value for the Company’s PCS contracts based on the renewal rate. The remaining value of the software arrangement is allocated to the license fee using the residual method. License revenue is primarily recognized when the software has been delivered and fair value has been established for all remaining undelivered elements. In cases where VSOE of fair value for PCS is not established, revenue is recognized ratably over the PCS period after all software deliverables have been made and the only the undelivered element is PCS. For services performed on a fixed-fee basis, revenue is recognized using the proportional performance method, with performance measured based on hours of work performed. For contracts that involve significant customization and implementation or consulting services that are essential to the functionality of the software, the license and services revenues are recognized using the percentage-of-completion method or, if we are unable to reliably estimate the costs to complete the services, we use the completed-contract method of accounting. A contract is considered complete when all significant costs have been incurred or when acceptance from the customer has been received. Some of the Company’s subscription product offerings include hardware, subscription services and extended warranty. Under these hosted arrangements, the customer typically does not have the contractual right to take possession of the software at any time during the hosting period without incurring a significant penalty and it is not feasible for the customer to run the software either on its own hardware or on a third-party’s hardware. The Company’s multiple deliverable product offerings include hardware with embedded firmware, extended warranty, software, PCS and subscription services, which are considered separate units of accounting. For certain of the Company’s products, software and non-software components function together to deliver the tangible product’s essential functionality. In evaluating the revenue recognition for the Company's hardware or subscription agreements which contain multiple deliverables, the Company determined that in certain instances the Company was not able to establish VSOE for some or all deliverables in an arrangement as the Company infrequently sold each element on a standalone basis, did not price products within a narrow range, or had a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on relevant third-party evidence (TPE). TPE is determined based on competitor prices for similar deliverables when sold separately. The Company’s offerings may contain a significant level of proprietary technology, customization or differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company typically is not able to establish the selling price of an element based on TPE. When the Company is unable to establish selling price using VSOE or TPE, the Company uses its best estimate of selling price (BESP) in the Company’s allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings. The Company determines BESP for a product or service by considering multiple factors including, but not limited to, pricing practices, market conditions, competitive landscape, internal costs, geographies and gross margin. The determination of BESP is made through consultation with and formal approval by the Company’s management, taking into consideration the Company’s go-to-market strategy.
Advertising Costs	Advertising Costs The Company expenses all advertising costs as incurred. Advertising expense was approximately $32.3 million , $39.0 million , and $33.8 million , in fiscal 2015 , 2014 and 2013 , respectively.
Research And Development Costs	Research and Development Costs Research and development costs are charged to expense as incurred. Cost of software developed for external sale subsequent to reaching technical feasibility were not significant and were expensed as incurred. The Company received third party funding of approximately $12.5 million , $13.5 million , and $5.1 million in fiscal 2015 , 2014 and 2013 , respectively. The Company offsets research and development expense with any third party funding earned. The Company retains the rights to any technology developed under such arrangements.
Stock-Based Compensation	Stock-Based Compensation The Company has employee stock benefit plans, which are described more fully in “Note 13: Employee Stock Benefit Plans.” Stock compensation expense recognized in the Consolidated Statements of Income is based on the fair value of the portion of share-based payment awards that is expected to vest during the period and is net of estimated forfeitures. The Company attributes the value of stock options to expense using the straight-line single option method. The grant date fair value for options is estimated using the binomial valuation model. The fair value of rights to purchase shares under the Employee Stock Purchase Plan is estimated using the Black-Scholes option-pricing model. The fair value of restricted stock units is valued as of the grant date using the fair value of Trimble’s common stock. The fair value for restricted stock units with market-based vesting conditions is valued as of the grant date using a Monte Carlo simulation. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records stock-based compensation expense only for those awards that are expected to vest. Fair value of Restricted Stock Units The fair value of restricted stock units is valued as of the grant date using the fair value of Trimble’s common stock. The weighted average grant-date fair value per share of RSUs granted during fiscal years 2015 , 2014 and 2013 was $23.22 , $30.18 , and $28.17 per share, respectively. The fair value of all restricted stock units vested during fiscal years 2015, 2014 and 2013 was $16.3 million , $3.9 million and $10.0 million , respectively. Fair Value of Market-Based Restricted Stock Units Restricted stock units with market-based vesting conditions vest based on the achievement of the Company’s relative total shareholder return (TSR) of its common stock as compared to the TSR of the constituents of the S&P 500 at the start of the performance period. The fair value of restricted stock units with market-based vesting conditions is valued as of the grant date using a Monte Carlo simulation, using the following weighted-average assumptions: Fiscal Years 2015 Expected life of options 2.6 years Expected stock price volatility 30.9 % Risk free interest rate 0.9 % Expected dividend yield — The weighted average grant-date fair value of the restricted stock units with market-based vesting conditions granted during fiscal 2015 was $31.60 per share. Unrecognized Stock-Based Compensation At the end of fiscal 2015, total unamortized stock-based compensation expense was $94.6 million , with a weighted-average recognition period of 2.1 years. Fair value of Stock Options The fair value of stock compensation is valued as of the grant date using a binomial valuation model. The binomial model takes into account variables such as volatility, dividend yield rate, and risk free interest rate. In addition, the binomial model incorporates actual option-pricing behavior and changes in volatility over the option’s contractual term. For options granted during fiscal 2015, 2014 and 2013, the following weighted-average assumptions were used: Fiscal Years 2015 2014 2013 Expected life of options 3.9 years 4.0 years 3.9 years Expected stock price volatility 36 % 35 % 35 % Risk free interest rate 1.26 % 1.29 % 0.69 % Expected dividend yield — — — Expected Life of Options —The Company’s expected life represents the period that the Company’s stock options are expected to be outstanding and was determined based on historical experience of similar stock options with consideration for the contractual terms of the stock options, vesting schedules and expectations of future employee behavior. Expected Stock Price Volatility —The Company’s computation of expected volatility is based on a combination of implied volatilities from traded options on the Company’s stock and historical volatility, commensurate with the expected life of the stock options. Expected Risk Free Interest Rate —The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected life of the option. Expected Dividend Yield —The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. The weighted average grant-date fair value per share of stock options granted during fiscal years 2015 , 2014 and 2013 was $7.36 , $9.07 , and $7.90 , respectively. The fair value of all stock options vested during fiscal years 2015, 2014 and 2013 was $18.3 million , $20.5 million and $20.3 million , respectively. Fair value of Restricted Stock Units The fair value of restricted stock units is valued as of the grant date using the fair value of Trimble’s common stock. The weighted average grant-date fair value per share of RSUs granted during fiscal years 2015 , 2014 and 2013 was $23.22 , $30.18 , and $28.17 per share, respectively. The fair value of all restricted stock units vested during fiscal years 2015, 2014 and 2013 was $16.3 million , $3.9 million and $10.0 million , respectively. Fair Value of Market-Based Restricted Stock Units Restricted stock units with market-based vesting conditions vest based on the achievement of the Company’s relative total shareholder return (TSR) of its common stock as compared to the TSR of the constituents of the S&P 500 at the start of the performance period. The fair value of restricted stock units with market-based vesting conditions is valued as of the grant date using a Monte Carlo simulation, using the following weighted-average assumptions: Fiscal Years 2015 Expected life of options 2.6 years Expected stock price volatility 30.9 % Risk free interest rate 0.9 % Expected dividend yield — The weighted average grant-date fair value of the restricted stock units with market-based vesting conditions granted during fiscal 2015 was $31.60 per share. Fair Value of Share Purchase Rights The fair value of the share purchase rights granted under the Purchase Plan are valued using the Black-Scholes option pricing model with the following weighted-average assumptions: Fiscal Years 2015 2014 2013 Expected life of purchase 0.5 years 0.5 years 0.5 years Expected stock price volatility 31.3 % 30.5 % 31.5 % Risk free interest rate 0.08 % 0.07 % 0.12 % Expected dividend yield — — — Expected Life of Purchase— The Company’s expected life of the purchase is based on the term of the offering period of the purchase plan. Expected Stock Price Volatility —The Company’s computation of expected volatility is based on implied volatilities from traded options on the Company’s stock. The Company used implied volatility because it is representative of future stock price trends during the purchase period. Expected Risk Free Interest Rate —The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the purchase period. Expected Dividend Yield —The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. The weighted average grant-date fair value per share of stock purchase rights granted under the Employee Stock Purchase Plan during fiscal years 2015 , 2014 and 2013 was $5.24 , $8.32 and $8.05 per share, respectively.
Income Taxes	Income Taxes Income taxes are accounted for under the liability method whereby deferred tax assets or liability account balances are calculated at the balance sheet date using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not such assets will not be realized. The Company’s valuation allowance is primarily attributable to foreign net operating losses and state research and development credit carryforwards. Management believes that it is more likely than not that the Company will not realize certain of these deferred tax assets, and, accordingly, a valuation allowance has been provided for such amounts. Valuation allowance adjustments associated with an acquisition after the measurement period are recorded through income tax expense. Relative to uncertain tax positions, the Company only recognizes a tax benefit if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and may not accurately forecast actual tax audit outcomes. Determining whether an uncertain tax position is effectively settled requires judgment. Changes in recognition or measurement of the Company's uncertain tax positions would result in the recognition of a tax benefit or an additional charge to the tax provision. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company is subject to income taxes in the U.S. and numerous other countries, and is subject to routine corporate income tax audits in many of these jurisdictions. The Company generally believes that positions taken on its tax returns are more likely than not to be sustained upon audit, but tax authorities in some circumstance have, and may in the future, successfully challenge these positions. Accordingly, the Company’s income tax provision includes amounts intended to satisfy assessments that may result from these challenges. Determining the income tax provision for these potential assessments and recording the related effects requires management judgments and estimates. The amounts ultimately paid on resolution of an audit could be materially different from the amounts previously included in the Company’s income tax provision and, therefore, could have a material impact on its income tax provision, net income and cash flows. The Company’s accrual for uncertain tax positions includes uncertainties concerning the tax treatment of our international operations, including the allocation of income among different jurisdictions, intercompany transactions and related interest. See Note 11 to the Consolidated Financial Statements for additional information.
Computation Of Earnings Per Share	Computation of Earnings Per Share The number of shares used in the calculation of basic earnings per share represents the weighted average common shares outstanding during the period and excludes any potentially dilutive securities. The dilutive effects of outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan and restricted stock units are included in diluted earnings per share.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The Company adopted the amendments beginning in the first quarter of fiscal 2015. The adoption did not have a material impact on the Company’s Condensed Consolidated Financial Statements. In May 2014, the FASB issued a comprehensive new revenue recognition standard that replaces the current revenue recognition guidance under U.S. GAAP. The new standard requires companies to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The revised effective date for the Company under the new standard will be the beginning of fiscal 2018, with early adoption permitted as of the original effective date. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company is currently evaluating the effect of the updated standard on its consolidated financial statements and related disclosures. In February 2015, the FASB issued amendments to the consolidation guidance. The amendments under the new guidance modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities and eliminate the presumption that a general partner should consolidate a limited partnership. The standard is effective for the Company in fiscal 2016, although early adoption is permitted. The Company does not anticipate a material impact on its consolidated financial statements as a result of the amendments. In April 2015, the FASB issued amendments to the guidance for debt issuance costs that will require debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability instead of being recorded as an asset. Amortization of the costs will continue to be reported as interest expense. The amendments are effective for the Company beginning in fiscal 2016. However, early adoption is permitted and the Company adopted this standard in the fourth quarter of fiscal 2015. The new guidance was applied retrospectively to each prior period presented. The Consolidated Balance Sheet at the end of fiscal 2014 reflects reclassification of unamortized debt issuance costs associated with the issuance of the Notes of $0.3 million from Other current assets and $2.7 million from Other non-current assets to Long-term debt. The debt issuance costs related to the Company’s credit facilities will continue to be presented as assets on the Consolidated Balance Sheet. In July 2015, the FASB issued amendments to simplify the measurement of inventory. Under the amendments, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The guidance defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation”. No other changes were made to the current guidance on inventory measurement. The amendments are effective for the Company beginning in fiscal 2017, although early adoption is permitted. The Company is currently evaluating the effect of the updated standard on its consolidated financial statements and related disclosures. In September 2015, the FASB issued new guidance related to business combinations. The new guidance requires that any adjustments to provisional amounts in a business combination be recorded in the period such adjustments are determined, rather than retrospectively adjusting previously reported amounts. The standard is effective for the Company in fiscal 2016, although early adoption is permitted. The Company is currently evaluating the effect of the updated standard on its consolidated financial statements and related disclosures. In November 2015, the FASB issued new guidance for balance sheet classification of deferred taxes, which requires that all deferred income tax assets and liabilities be classified as noncurrent in the balance sheet. The standard may be applied either prospectively or retrospectively and is effective for the Company beginning in fiscal 2016. However, early adoption is permitted and the Company adopted this standard in the fourth quarter of fiscal 2015 on a prospective basis. The adoption of this new accounting guidance resulted in all deferred tax assets and liabilities being classified as non-current in the Company’s consolidated balance sheet for fiscal 2015. Prior periods were not retrospectively adjusted. See “Note 11: Income Taxes” for additional information related to the presentation of deferred income tax assets and liabilities. In January 2016, the FASB issued changes to the accounting for financial instruments that primarily affect equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The amendments are effective for the Company beginning in fiscal 2018, although early adoption is permitted. The new standard should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with certain exceptions. The Company is currently evaluating the effect of the updated standard on its consolidated financial statements and related disclosures.
