Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation General The accompanying unaudited condensed consolidated financial statements include the accounts of PTC Inc. and its wholly owned subsidiaries and have been prepared by management in accordance with accounting principles generally accepted in the United States of America and in accordance with the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. While we believe that the disclosures presented are adequate in order to make the information not misleading, these unaudited quarterly financial statements should be read in conjunction with our annual consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2015 . In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of those of a normal recurring nature, necessary for a fair statement of our financial position, results of operations and cash flows at the dates and for the periods indicated. Unless otherwise indicated, all references to a year mean our fiscal year, which ends on September 30. The September 30, 2015 Consolidated Balance Sheet included herein is derived from our audited consolidated financial statements. The results of operations for the three months ended January 2, 2016 are not necessarily indicative of the results expected for the remainder of the fiscal year. Income Statement Presentation In 2015, we classified revenue in three categories: 1) license and subscription solutions; 2) support; and 3) professional services. Effective with the beginning of the first quarter of 2016, we are reporting perpetual license revenue separately from the subscription revenue and are presenting revenue in four categories: 1) subscription; 2) support; 3) perpetual license; and 4) professional services. Effective with the beginning of the first quarter of 2016, we reclassified certain expenses related to management of our product lines from general and administrative to marketing. Revenue and costs and expenses in the accompanying Consolidated Statements of Operations have been reclassified to conform to the current period presentation. Recent Accounting Pronouncements Deferred Taxes In November, 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740) , to simplify the presentation of deferred income taxes. The amendments in this Update require that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that permits offsetting only within a jurisdiction and companies are still prohibited from offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. ASU 2015-17 is effective for public companies for fiscal years beginning after December 15, 2016, with early adoption permitted for all entities as of the beginning of an interim or annual reporting period. This guidance may be applied either prospectively or retrospectively (by reclassifying the comparative balance sheet). We adopted this new guidance in our first quarter ended January 2, 2016 and applied this guidance prospectively. As a result, the deferred tax assets and deferred tax liabilities on the Consolidated Balance Sheet as of September 30, 2015 have not been reclassified to conform to the January 2, 2016 presentation. Revenue Recognition In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In July 2015, the FASB approved a one-year delay in the effective date. ASU 2014-09 is effective for us in our first quarter of fiscal 2019 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements. Debt Issuance Costs In April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30), to simplify the required presentation of debt issuance costs. The amended guidance requires that debt issuance costs be presented in the balance sheet as a direct reduction from the carrying amount of the related debt liability rather than as an asset. It is effective for financial statements issued for fiscal years beginning after December 15, 2015, our fiscal 2017, with early adoption permitted. The new guidance will be applied retrospectively to each prior period presented. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

Deferred Revenue And Financing Receivables [Abstract]
Deferred Revenue and Financing Receivables	Deferred Revenue and Financing Receivables Deferred Revenue Deferred revenue primarily relates to software support agreements billed to customers for which the services have not yet been provided. The liability associated with performing these services is included in deferred revenue and, if not yet paid, the related customer receivable is included in prepaid expenses and other current assets. Billed but uncollected support and subscription-related amounts included in prepaid expenses and other current assets at January 2, 2016 and September 30, 2015 were $133.9 million and $129.3 million , respectively. Financing Receivables We periodically provide extended payment terms to credit-worthy customers for software purchases with payment terms up to 24 months. The determination of whether to offer such payment terms is based on the size, nature and credit-worthiness of the customer, and the history of collecting amounts due, without concession, from the customer and customers generally. This determination is based on an internal credit assessment. In making this assessment, we use the Standard & Poor's (S&P) credit rating as our primary credit quality indicator, if available. If a customer, whether commercial or the U.S. Federal government, has an S&P bond rating of BBB- or above, we designate the customer as Tier 1. If a customer does not have an S&P bond rating, or has an S&P bond rating below BBB-, we base our assessment on an internal credit assessment which considers selected balance sheet, operating and liquidity measures, historical payment experience, and current business conditions within the industry or region. We designate these customers as Tier 2 or Tier 3, with Tier 3 being lower credit quality than Tier 2. As of January 2, 2016 and September 30, 2015 , amounts due from customers for contracts with original payment terms greater than twelve months (financing receivables) totaled $26.6 million and $27.4 million , respectively. Accounts receivable and prepaid expenses and other current assets in the accompanying Consolidated Balance Sheets included current receivables from such contracts totaling $20.4 million and $21.8 million at January 2, 2016 and September 30, 2015 , respectively, and other assets in the accompanying Consolidated Balance Sheets included long-term receivables from such contracts totaling $6.2 million and $5.6 million at January 2, 2016 and September 30, 2015 , respectively. As of January 2, 2016 and September 30, 2015 , $0.8 million and $0.5 million , respectively, of these receivables were past due. Our credit risk assessment for financing receivables was as follows: January 2, September 30, (in thousands) S&P bond rating BBB-1 and above-Tier 1 $ 19,258 $ 16,841 Internal Credit Assessment-Tier 2 7,339 10,593 Internal Credit Assessment-Tier 3 — — Total financing receivables $ 26,597 $ 27,434 We evaluate the need for an allowance for doubtful accounts for estimated losses resulting from the inability of these customers to make required payments. As of January 2, 2016 and September 30, 2015 , we concluded that all financing receivables were collectible and no reserve for credit losses was recorded. We did not provide a reserve for credit losses or write off any uncollectible financing receivables in the three months ended January 2, 2016 or January 3, 2015 . We write off uncollectible trade and financing receivables when we have exhausted all collection avenues. We periodically transfer future payments under certain of these contracts to third-party financial institutions on a non-recourse basis. We record such transfers as sales of the related accounts receivable when we surrender control of such receivables. We did not sell any financing receivables to third-party financial institutions in the three months ended January 2, 2016 and January 3, 2015 .

Restructuring [Abstract]
Restructuring Charges	Restructuring Charges On October 23, 2015, we initiated a plan to restructure our workforce and consolidate select facilities in order to reduce our cost structure and to realign our investments with what we believe to be our higher growth opportunities. The restructuring is expected to result in a charge of up to $50 million , which is primarily attributable to termination benefits. In the first quarter of 2016, we recorded a charge of $36.8 million , attributable to termination benefits associated with 432 employees. The remaining charges are expected to be recorded predominantly in the second and third quarters of 2016. In the first quarter of 2016, we recorded a charge of $0.2 million related to employee terminations and $0.2 million related to excess facilities associated with our restructuring actions initiated in the second quarter of 2015. As of January 2, 2016, this restructuring plan was substantially completed. The following table summarizes restructuring accrual activity for the three months ended January 2, 2016 : Employee Severance and Related Benefits Facility Closures and Related Costs Total (in thousands) October 1, 2015 $ 14,086 $ 1,168 $ 15,254 Charge to operations 36,961 186 37,147 Cash disbursements (16,269 ) (433 ) (16,702 ) Foreign exchange impact (81 ) (36 ) (117 ) Accrual, January 2, 2016 $ 34,697 $ 885 $ 35,582 The accrual for facility closures and related costs is included in accrued expenses and other liabilities in the Consolidated Balance Sheets, and the accrual for employee severance and related benefits is included in accrued compensation and benefits in the Consolidated Balance Sheets.

Stock-based Compensation

Stock-based Compensation	3 Months Ended

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]
Stock-Based Compensation	Stock-based Compensation We measure the cost of employee services received in exchange for restricted stock unit (RSU) awards based on the fair value of RSU awards on the date of grant. That cost is recognized over the period during which an employee is required to provide service in exchange for the award. Our equity incentive plan provides for grants of nonqualified and incentive stock options, common stock, restricted stock, RSUs and stock appreciation rights to employees, directors, officers and consultants. We award RSUs as the principal equity incentive awards, including certain performance-based awards that are earned based on achievement of performance criteria established by the Compensation Committee of our Board of Directors. Each RSU represents the contingent right to receive one share of our common stock. Restricted stock unit activity for the three month ended January 2, 2016 Shares Weighted Average Grant Date Fair Value (Per Share) (in thousands) Balance of outstanding restricted stock units October 1, 2015 3,654 $ 33.64 Granted 1,753 $ 38.22 Vested (1,209 ) $ 28.67 Forfeited or not earned (215 ) $ 35.78 Balance of outstanding restricted stock units January 2, 2016 3,983 $ 37.04 Restricted Stock Units Grant Period TSR Units (1) Performance-based RSUs (2) Service-based RSUs (2) (Number of Units in thousands) First three months of 2016 326 343 1,083 _________________ (1) The TSR units were granted to our executive officers pursuant to the terms described below. (2) The service-based RSUs were issued to both employees and our executive officers. In addition, executive officers may earn up to one or, for our CEO, two times the number of time-based RSUs (up to a maximum of 343,000 shares) if certain performance conditions are met. Of the service-based RSUs, approximately 110,000 shares will vest in two substantially equal annual installments on or about the anniversary of the date of grant. All other service-based RSUs will vest in three substantially equal annual installments on or about the anniversary of the date of grant. The performance-based RSUs will vest in three substantially equal installments on the later of November 15, 2016, November 15, 2017 and November 15, 2018, or the date the Compensation Committee determines the extent to which the applicable performance criteria have been achieved. In the first three months of 2016, we granted the target performance-based TSR units ("target RSUs") shown in the table above to our executive officers. These RSUs are eligible to vest based upon our total shareholder return relative to a peer group (the “TSR units”), measured annually over a three-year period. The number of TSR units to vest over the three year period will be determined based on the performance of PTC stock relative to the stock performance of an index of PTC peer companies established as of the grant date, as determined at the end of three measurement periods ending on September 30, 2016, 2017 and 2018, respectively. The shares earned for each period will vest on November 15 following each measurement period, up to a maximum of two times the number of target RSUs (up to a maximum of 652,000 shares). No vesting will occur in a period unless an annual threshold requirement is achieved. The employee must remain employed by PTC through the applicable vest date for any RSUs to vest. If the return to PTC shareholders is negative but still meets or exceeds the peer group indexed return, a maximum of 100% of the target RSUs shall vest for the measurement period. TSR units not earned in the first two year measurement periods are eligible to be earned in the third measurement period. The weighted average fair value of the TSR units was $46.96 per target RSU on the grant date. The fair value of the TSR units was determined using a Monte Carlo simulation model, a generally accepted statistical technique used to simulate a range of possible future stock prices for PTC and the peer group. The method uses a risk-neutral framework to model future stock price movements based upon the risk-free rate of return, the volatility of each entity, and the pairwise correlations of each entity being modeled. The fair value for each simulation is the product of the payout percentage determined by PTC’s TSR rank against the peer group, the projected price of PTC stock, and a discount factor based on the risk-free rate. The significant assumptions used in the Monte Carlo simulation model were as follows: Average volatility of peer group 28.1 % Risk free interest rate 1.05 % Dividend yield — % Compensation expense recorded for our stock-based awards was classified in our Consolidated Statements of Operations as follows: Three months ended January 2, January 3, (in thousands) Cost of software revenue $ 1,905 $ 918 Cost of professional services revenue 1,451 1,689 Sales and marketing 4,282 3,201 Research and development 2,513 3,086 General and administrative 13,038 2,348 Total stock-based compensation expense $ 23,189 $ 11,242 The stock-based compensation expense in the first quarter of 2016 included $10 million of expense related to modifications of certain performance-based RSUs previously granted under our long-term incentive programs. The Compensation Committee of our Board of Directors amended these equity awards due to the impact of changes in our business model and strategy and foreign currency on our financial results.

Earnings Per Share and Common Stock
Earnings(loss) per Share (EPS) and Common Stock	Earnings per Share (EPS) and Common Stock EPS Basic EPS is calculated by dividing net income by the weighted average number of shares outstanding during the period. Unvested restricted stock, although legally issued and outstanding, is not considered outstanding for purposes of calculating basic EPS. Diluted EPS is calculated by dividing net income by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and RSUs using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options, unrecognized compensation expense and any tax benefits as additional proceeds. Three months ended Calculation of Basic and Diluted EPS January 2, January 3, (in thousands, except per share data) Net income (loss) $ (23,892 ) $ 30,284 Weighted average shares outstanding—Basic 114,151 115,341 Dilutive effect of employee stock options, restricted shares and restricted stock units — 1,686 Weighted average shares outstanding—Diluted 114,151 117,027 Earnings (loss) per share—Basic $ (0.21 ) $ 0.26 Earnings (loss) per share—Diluted $ (0.21 ) $ 0.26 For the three months ended January 2, 2016, diluted net loss per share is the same as basic net loss per share as the effects of our potential common stock equivalents are antidilutive. Total antidilutive shares were 2.0 million for the three months ended January 2, 2016. Common Stock Repurchases Our Articles of Organization authorize us to issue up to 500 million shares of our common stock. Our Board of Directors has periodically authorized the repurchase of shares of our common stock. On August 4, 2014, our Board of Directors authorized us to repurchase up to $600 million of our common stock through September 30, 2017. In the first quarter of 2016, we did not repurchase any shares. In the first quarter of 2015, we received 1.1 million shares as the final settlement of the accelerated share repurchase ("ASR") agreement described below. All shares of our common stock repurchased are automatically restored to the status of authorized and unissued. On August 14, 2014, we entered into an accelerated share repurchase (“ASR”) agreement with a major financial institution (“Bank”). The ASR allowed us to buy a large number of shares immediately at a purchase price determined by an average market price over a period of time. Under the ASR, we agreed to purchase $125 million of our common stock, in total, with an initial delivery to us in August 2014 of 2.3 million shares. We settled the ASR in December 2014 and the Bank delivered to us an additional 1.1 million shares.

Business Combinations [Abstract]
Acquisition	Acquisitions Acquisition-related costs were $1.2 million and $4.0 million for the first quarter of 2016 and 2015, respectively. Acquisition-related costs include direct costs of potential and completed acquisitions (e.g., investment banker fees, professional fees, including legal and valuation services) and expenses related to acquisition integration activities (e.g., professional fees, severance, and retention bonuses). In addition, subsequent adjustments to our initial estimated amount of contingent consideration associated with specific acquisitions are included within acquisition-related charges. These costs have been classified in general and administrative expenses in the accompanying Consolidated Statements of Operations. Vuforia On November 3, 2015 , pursuant to an Asset Purchase Agreement, PTC acquired the Vuforia business from Qualcomm Connected Experiences, Inc., a subsidiary of Qualcomm Incorporated, for $64.8 million in cash (net of cash acquired of $4.5 million ). We borrowed $50 million under our credit facility to finance this acquisition. At the time of the acquisition, Vuforia had approximately 80 employees and historical annualized revenues were not material. The results of operations of Vuforia have been included in our consolidated financial statements beginning on the acquisition date. Vuforia added $0.3 million to our revenue and $4.1 million in costs and expenses in the first quarter of 2016. The acquisition of Vuforia has been accounted for as a business combination. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the acquisition date. The fair values of intangible assets were based on valuations using a cost approach which requires the use of significant estimates and assumptions, including estimating costs to reproduce an asset. The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. The purchase price allocation resulted in $23.3 million of goodwill, $41.2 million of technology and $4.7 million of net tangible assets. The acquired technology is being amortized over weighted average useful lives of 6 years. All of the acquired goodwill was allocated to our software products segment and will be deductible for income tax purposes. The resulting amount of goodwill reflects the value of the synergies created by integrating Vuforia’s augmented technology platform into PTC’s Technology Platform solutions. ColdLight In the third quarter of 2015, we acquired ColdLight Solutions, LLC, for approximately $98.6 million in cash (net of cash acquired of $1.3 million ). The former shareholders of ColdLight are eligible to receive additional consideration (the earn-out) of up to $5 million which is contingent upon achievement of certain technology milestones within two years of the acquisition. If an earn-out milestone is achieved, a portion of the contingent consideration becomes earned and payable in cash after each six-month period. In connection with accounting for the business combination, we recorded a liability $3.8 million , representing the fair value of the contingent consideration. The liability was valued using a discounted cash flow method and a probability weighted estimate of achievement of the technology milestones. The estimated undiscounted range of outcomes for the contingent consideration was $3.8 million to $5.0 million at the acquisition date. As of January 2, 2016, our estimate of the liability was $2.8 million , after a payment of $1.3 million made in December 2015. The payment was included in financing activities in the Consolidated Statements of Cash Flows. We will continue to assess the probability that the unearned milestones will be met and at what level each reporting period. Changes in the estimated fair value of the liability are reflected in earnings until the liability is fully settled. ThingWorx In the second quarter of 2014, we acquired ThingWorx, Inc. for $111.5 million (net of cash acquired of $0.1 million ). The former shareholders of ThingWorx are eligible to receive additional consideration of up to $18.0 million if certain profitability and bookings targets are achieved within two years of the acquisition from December 30, 2013 to January 1, 2016. The earn-out is payable in cash in two installments after each measurement period. In connection with accounting for the business combination, we recorded a liability representing the fair value of the contingent consideration. The liability was valued using a discounted cash flow method and a probability weighted estimate of achievement of the financial targets. We assess the probability that the targets will be met each reporting period. Any subsequent changes in the estimated fair value of the liability are reflected in earnings until the liability is fully settled. The first year payment criteria were attained and we paid $9 million of the total contingent consideration in July 2015. As of January 2, 2016, the remaining $9.0 million of the total contingent consideration is fully earned and becomes payable in the second quarter of 2016.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets We have two operating segments: (1) Software Products and (2) Services. We assess goodwill for impairment at the reporting unit level. Our reporting units are determined based on the components of our operating segments that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by segment management. Our reporting units are the same as our operating segments. As of January 2, 2016 and September 30, 2015 , goodwill and acquired intangible assets in the aggregate attributable to our software products segment were $1,342.0 million and $1,297.9 million , respectively, and attributable to our services segment were $61.9 million and $62.4 million , respectively. Acquired intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. We evaluate goodwill for impairment in the third quarter of our fiscal year, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of a reporting segment below its carrying value. Factors we consider important, on an overall company basis and segment basis, when applicable, that could trigger an impairment review include significant under-performance relative to historical or projected future operating results, significant changes in our use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, a significant decline in our stock price for a sustained period and a reduction of our market capitalization relative to net book value. We completed our annual goodwill impairment review as of July 4, 2015 and concluded that no impairment charge was required as of that date. To conduct these tests of goodwill, the fair value of the reporting unit is compared to its carrying value. If the reporting unit’s carrying value exceeds its fair value, we record an impairment loss equal to the difference between the carrying value of goodwill and its implied fair value. We estimate the fair values of our reporting units using discounted cash flow valuation models. Those models require estimates of future revenues, profits, capital expenditures, working capital, terminal values based on revenue multiples, and discount rates for each reporting unit. We estimate these amounts by evaluating historical trends, current budgets, operating plans and industry data. The estimated fair value of each reporting unit was more than double its carrying value as of July 4, 2015. Goodwill and acquired intangible assets consisted of the following: January 2, 2016 September 30, 2015 Gross Carrying Amount Accumulated Amortization Net Book Value Gross Carrying Amount Accumulated Amortization Net Book Value (in thousands) Goodwill (not amortized) $ 1,086,230 $ 1,069,041 Intangible assets with finite lives (amortized) (1): Purchased software $ 323,762 $ 178,483 $ 145,279 $ 284,257 $ 174,887 $ 109,370 Capitalized software 22,877 22,877 — 22,877 22,877 — Customer lists and relationships 347,011 180,417 166,594 349,938 174,017 175,921 Trademarks and trade names 18,432 12,814 5,618 18,534 12,759 5,775 Other 3,905 3,726 179 3,946 3,711 235 $ 715,987 $ 398,317 $ 317,670 $ 679,552 $ 388,251 $ 291,301 Total goodwill and acquired intangible assets $ 1,403,900 $ 1,360,342 (1) The weighted average useful lives of purchased software, customer lists and relationships, trademarks and trade names and other intangible assets with a remaining net book value are 8 years, 10 years, 10 years, and 3 years, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance. Generally accepted accounting principles prescribe a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs that may be used to measure fair value: • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or • Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our significant financial assets and liabilities measured at fair value on a recurring basis as of January 2, 2016 and September 30, 2015 were as follows: January 2, 2016 Level 1 Level 2 Level 3 Total (in thousands) Financial assets: Cash equivalents (1) $ 76,480 $ — $ — $ 76,480 Forward contracts (2) — 1,479 — 1,479 $ 76,480 $ 1,479 $ — $ 77,959 Financial liabilities: Contingent consideration related to acquisitions (3) $ — $ — $ 11,750 $ 11,750 Forward contracts (2) — 365 — 365 $ — $ 365 $ 11,750 $ 12,115 September 30, 2015 Level 1 Level 2 Level 3 Total (in thousands) Financial assets: Cash equivalents (1) $ 91,216 $ — $ — $ 91,216 Forward contracts (2) — 507 — 507 $ 91,216 $ 507 $ — $ 91,723 Financial liabilities: Contingent consideration related to acquisitions (3) $ — $ — $ 13,000 $ 13,000 Forward contracts (2) — 46 — 46 $ — $ 46 $ 13,000 $ 13,046 ______________ (1) Money market funds and time deposits are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. (2) The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants usually are large financial institutions. Our foreign currency contracts’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy. (3) For a description of the inputs used to value the contingent consideration liability see Note 6 Acquisitions. Changes in the fair value of Level 3 contingent consideration liability associated with our acquisition of ThingWorx and ColdLight were as follows: Contingent Consideration (in thousands) ThingWorx ColdLight Balance, October 1, 2015 $ 9,000 $ 4,000 Change in present value of contingent consideration — — Payment of contingent consideration (1,250 ) Balance, January 2, 2016 $ 9,000 $ 2,750 Of the total, $10.2 million of the contingent consideration liabilities are included in accrued expenses and other current liabilities, with the remaining $1.5 million in other liabilities in the Consolidated Balance Sheet as of January 2, 2016.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Our earnings and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. Our most significant foreign currency exposures relate to Western European countries, Japan, China and Canada. Our foreign currency risk management strategy is principally designed to mitigate the future potential financial impact of changes in the U.S. dollar value of anticipated transactions and balances denominated in foreign currency, resulting from changes in foreign currency exchange rates. We enter into derivative transactions, specifically foreign currency forward contracts, to manage the exposures to foreign currency exchange risk to reduce earnings volatility. We do not enter into derivatives transactions for trading or speculative purposes. Non-Designated Hedges We hedge our net foreign currency monetary assets and liabilities primarily resulting from foreign currency denominated receivables and payables with foreign exchange forward contracts to reduce the risk that our earnings and cash flows will be adversely affected by changes in foreign currency exchange rates. These contracts have maturities of up to approximately 3 months. Generally, we do not designate these foreign currency forward contracts as hedges for accounting purposes and changes in the fair value of these instruments are recognized immediately in earnings. Because we enter into forward contracts only as an economic hedge, any gain or loss on the underlying foreign-denominated balance would be offset by the loss or gain on the forward contract. Gains and losses on forward contracts and foreign denominated receivables and payables are included in other income (expense), net. As of January 2, 2016 and September 30, 2015 , we had outstanding forward contracts with notional amounts equivalent to the following: Currency Hedged January 2, September 30, (in thousands) Canadian / U.S. Dollar $ 16,528 $ 17,448 Euro / U.S. Dollar 80,639 82,917 British Pound / Euro 1,855 9,409 Israeli New Sheqel / U.S. Dollar 4,108 4,607 Japanese Yen / Euro 16,564 25,133 Swiss Franc / U.S. Dollar 353 5,149 All other 10,613 12,592 Total $ 130,660 $ 157,255 The following table shows the effect of our non-designated hedges in the Consolidated Statements of Operations for the three months ended January 2, 2016 and January 3, 2015 : Derivatives Not Designated as Hedging Instruments Location of Gain or (Loss) Recognized in Income Net realized and unrealized gain or (loss) (excluding the underlying foreign currency exposure being hedged) Three months ended January 2, January 3, (in thousands) Forward Contracts Other Income (Expense) $ (1,014 ) $ 297 Cash Flow Hedges Our foreign exchange risk management program objective is to identify foreign exchange exposures and implement appropriate hedging strategies to minimize earnings fluctuations resulting from foreign exchange rate movements. We designate certain foreign exchange forward contracts as cash flow hedges of Euro and Yen denominated intercompany forecasted transactions. All foreign exchange forward contracts are carried at fair value on the Consolidated Balance Sheets and the maximum duration of foreign exchange forward contracts does not exceed 13 months. Cash flow hedge relationships are designated at inception, and effectiveness is assessed prospectively and retrospectively using regression analysis on a monthly basis. As the forward contracts are highly effective in offsetting changes to future cash flows on the hedged transactions, we record the effective portion of changes in these cash flow hedges in accumulated other comprehensive income and subsequently reclassify into earnings in the same period during which the hedged transactions are recognized in earnings. Changes in the fair value of foreign exchange forward contracts due to changes in time value are included in the assessment of effectiveness. As of January 2, 2016 and September 30, 2015 , we had outstanding forward contracts designed as cash flow hedges with notional amounts equivalent to the following: Currency Hedged January 2, September 30, (in thousands) Euro / U.S. Dollar $ 33,815 $ — Yen / U.S. Dollar 18,018 — Total $ 51,833 $ — The following table shows the effect of the our derivative instruments designated as cash flow hedges in the Consolidated Statements of Operations for the three months ended January 2, 2016 and January 3, 2015 (in thousands): Derivatives Designated as Hedging Instruments Gain or (Loss)Recognized in OCI-Effective Portion Location of Gain or (Loss) Reclassified from OCI into Income-Effective Portion Gain or (Loss) Reclassified from OCI into Income-Effective Portion Location of Gain or (Loss) Recognized-Ineffective Portion Gain or (Loss) Recognized-Ineffective Portion Three months ended Three months ended Three months ended January 2, January 3, January 2, 2016 January 3, 2015 January 2, 2016 January 3, 2015 Forward Contracts $ 1,643 $ — Software Revenue $ 846 $ — Other Income (Expense) $ — $ — As of January 2, 2016, we estimated that all values reported in accumulated other comprehensive income will be reclassified to income within the next twelve months. In the event the underlying forecast transaction does not occur, or it becomes probable that it will not occur, the related hedge gains and losses on the cash flow hedge would be immediately reclassified to “Other Income (Expense)” on the Consolidated Statements of Operations. For the three months ended January 2, 2016 , there were no such gains or losses.

Segment Reporting [Abstract]
Segment Information	Segment Information We operate within a single industry segment—computer software and related services. Operating segments as defined under GAAP are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our President and Chief Executive Officer. We have two operating and reportable segments: (1) Software Products, which includes license and related support revenue (including updates and technical support) for all our products except training-related products; and (2) Services, which includes consulting, implementation, training, cloud services, computer-based training products, including support on these products, and other services revenue. We do not allocate sales and marketing or administrative expenses to our operating segments as these activities are managed on a consolidated basis. The revenue and operating income attributable to our operating segments are summarized as follows: Three months ended January 2, January 3, Revenue: Total Software Products segment revenue $ 225,537 $ 246,991 Total Services segment revenue 65,480 78,451 Total revenue $ 291,017 $ 325,442 Operating income (loss): (1) Software Products segment $ 117,888 $ 149,045 Services segment 9,078 13,200 Sales and marketing expenses (98,330 ) (89,484 ) General and administrative expenses (41,928 ) (35,130 ) Total operating income (loss) (13,292 ) 37,631 Interest and other expense, net (6,253 ) (3,224 ) Income (loss) before income taxes $ (19,545 ) $ 34,407 (1) We recorded restructuring charges of $37.1 million in the first quarter of 2016. Software Products included $13.0 million ; Services included $4.8 million ; sales and marketing expenses included $15.9 million ; and general and administrative expenses included $3.4 million , of these restructuring charges. We recorded a credit to restructuring of $0.3 million in the first quarter of 2015 which is included in the Services segment.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In the first quarter of 2016, our effective tax rate was (22)% on a pre-tax loss of $19.5 million , compared to a provision of 12% on pre-tax income of $34.4 million in the first quarter of 2015. In the first quarter of 2016 and 2015, our effective tax rate was lower than the 35% statutory federal income tax rate due to our corporate structure in which our foreign taxes are at a net effective tax rate lower than the U.S. rate. A significant amount of our foreign earnings is generated by our subsidiaries organized in Ireland. In 2016 and 2015, the foreign rate differential predominantly relates to these Irish earnings. Our foreign rate differential in 2016 and 2015 includes a rate benefit from a business realignment completed on September 30, 2014 in which intellectual property was transferred between two wholly-owned foreign subsidiaries. The realignment allows us to more efficiently manage the distribution of our products to European customers. This realignment resulted in a tax benefit of approximately $3 million and $4 million in the first quarter of 2016 and 2015, respectively. Additionally, in 2016 and 2015 our provision reflects a tax benefit of $2.6 million and $2.1 million respectively, related to a retroactive extension of the U.S. research and development tax credit enacted in the first quarter of 2016 and 2015. In 2016 and 2015, this benefit was offset by a corresponding provision to increase our U.S. valuation allowance. As of January 2, 2016 and September 30, 2015, we had unrecognized tax benefits of $14.4 million and $14.1 million , respectively. If all of our unrecognized tax benefits as of January 2, 2016 were to become recognizable in the future, we would record a benefit to the income tax provision of $12.8 million which would be partially offset by an increase in the U.S. valuation allowance of $4.6 million . Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in favorable or unfavorable changes in our estimates. We believe it is reasonably possible that within the next 12 months the amount of unrecognized tax benefits related to the resolution of multi-jurisdictional tax positions could be reduced by up to $4 million as audits close and statutes of limitations expire.

Debt Disclosure [Abstract]
Debt	Debt Credit Agreement In November 2015, we entered into a multi-currency credit facility with a syndicate of sixteen banks for which JPMorgan Chase Bank, N.A. acts as Administrative Agent. This credit facility amended and restated in its entirety our credit facility described in Note H of our Annual Report on Form 10-K for the fiscal year ended September 30, 2015. We expect to use the credit facility for general corporate purposes, including acquisitions of businesses, share repurchases and working capital requirements. As of January 2, 2016 , the fair value of our credit facility approximates its book value. The credit facility consists of a $1 billion revolving loan commitment, which may be increased by an additional $500 million (in the form of revolving loans or term loans, or a combination thereof) if the existing or additional lenders are willing to make such increased commitments. The revolving loan commitment does not require amortization of principal and may be repaid in whole or in part prior to the scheduled maturity date at our option without penalty or premium. The credit facility matures on September 15, 2019, when all remaining amounts outstanding will be due and payable in full. PTC and certain eligible foreign subsidiaries are eligible borrowers under the credit facility. The obligations under the credit facility are guaranteed by PTC and certain of its material domestic subsidiaries. In addition, PTC and certain of its material domestic subsidiaries' owned property (including equity interests) is subject to first priority perfected liens in favor of the lenders of this credit facility. 100% of the voting equity interests of certain of PTC’s domestic subsidiaries and 65% of its material first-tier foreign subsidiaries are pledged as collateral for the obligations under the credit facility. As of January 2, 2016 , we had $718.1 million in loans outstanding under the credit facility. In January 2016, we borrowed an additional $120 million for our acquisition of Kepware. Loans under the credit facility bear interest at variable rates which reset every 30 to 180 days depending on the rate and period selected by PTC as described below. As of January 2, 2016 , the weighted average annual interest rate for borrowing outstanding was 1.899% . Interest rates on borrowings outstanding under the credit facility range from 1.25% to 1.75% above an adjusted LIBO rate for Euro currency borrowings or would range from 0.25% to 0.75% above the defined base rate (the greater of the Prime Rate, the FRBNY rate plus 0.5% , or an adjusted LIBO rate plus 1% ) for base rate borrowings, in each case based upon PTC’s total leverage ratio. Additionally, PTC may borrow certain foreign currencies at rates set in the same range above the respective London interbank offered interest rates for those currencies, based on PTC’s total leverage ratio. A quarterly commitment fee on the undrawn portion of the credit facility is required, ranging from 0.175% to 0.30% per annum, based upon PTC’s total leverage ratio. The credit facility limits PTC’s and its subsidiaries’ ability to, among other things: incur liens or guarantee obligations; pay dividends (other than to PTC) and make other distributions; make investments and enter into joint ventures; dispose of assets; and engage in transactions with affiliates, except on an arms-length basis. Under the credit facility, PTC and its material domestic subsidiaries may not invest cash or property in, or loan to, PTC’s foreign subsidiaries in aggregate amounts exceeding $75.0 million for any purpose and an additional $200.0 million for acquisitions of businesses. In addition, under the credit facility, PTC and its subsidiaries must maintain the following financial ratios: • a total leverage ratio, defined as consolidated total indebtedness to the consolidated trailing four quarters EBITDA, not to exceed ◦ prior to a Covenant Modification Trigger Event (incurring unsecured indebtedness of not less than $200.0 million in aggregate) (x) 3.50 to 1.00 as of the last day of any fiscal quarter ending on or prior to July 2, 2016, and (y) 3.25 to 1.00 as of the last day of any fiscal quarter ending on or after September 30, 2016. ◦ on and after a Covenant Modification Trigger Event, 4.00 to 1.00 as of the last day of any fiscal quarter. • a senior secured leverage ratio, defined as senior consolidated total indebtedness (which excludes unsecured indebtedness) to the consolidated trailing four quarters EBITDA, not to exceed 3.00 to 1.00 as of the last day of any fiscal quarter ending after a Covenant Modification Trigger Event, and • a fixed charge coverage ratio, defined as the ratio of consolidated trailing four quarters EBITDA less consolidated capital expenditures to consolidated fixed charges, of not less than 3.50 to 1.00 as of the last day of any fiscal quarter. As of January 2, 2016 , our total leverage ratio was 2.68 to 1.00 , our fixed charge coverage ratio was 7.65 to 1.00 and we were in compliance with all financial and operating covenants of the credit facility. Any failure to comply with the financial or operating covenants of the credit facility would prevent PTC from being able to borrow additional funds, and would constitute a default, permitting the lenders to, among other things, accelerate the amounts outstanding, including all accrued interest and unpaid fees, under the credit facility and to terminate the credit facility. A change in control of PTC, as defined in the agreement, also constitutes an event of default, permitting the lenders to accelerate the indebtedness and terminate the credit facility.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal and Regulatory Matters China Investigation We have been in discussions with the U.S. Securities and Exchange Commission (SEC) and the Department of Justice (DOJ) to resolve a previously announced investigation concerning expenditures by our business partners in China and by our China business, including for travel and entertainment, that apparently benefited employees of customers regarded as state owned enterprises in China. This matter involves issues regarding compliance with laws, including the U.S. Foreign Corrupt Practices Act. In 2015, we recorded a liability of $28.2 million as a result of an agreement in principle to settle the matter with these agencies. There can be no assurance that we and these agencies will enter into final settlements on the foregoing terms or, if not, that the cost of any final settlements, if reached, would not exceed the existing accrual. Further, any settlement or other resolution of this matter could have collateral effects on our business in China, the United States and elsewhere. Legal Proceedings We are subject to various other legal proceedings and claims that arise in the ordinary course of business. We do not believe that resolving the legal proceedings and claims that we are currently subject to will have a material adverse impact on our financial condition, results of operations or cash flows. However, the results of legal proceedings cannot be predicted with certainty. Should any of these legal proceedings and claims be resolved against us, the operating results for a particular reporting period could be adversely affected. Accruals With respect to legal proceedings and claims, we record an accrual for a contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. For legal proceedings and claims for which the likelihood that a liability has been incurred is more than remote but less than probable, we estimate the range of possible outcomes. As of January 2, 2016 , we had a legal proceedings and claims accrual of $28.7 million , including an accrual of $28.2 million for the China investigation. Guarantees and Indemnification Obligations We enter into standard indemnification agreements in the ordinary course of our business. Pursuant to such agreements with our business partners or customers, we indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to our products, as well as claims relating to property damage or personal injury resulting from the performance of services by us or our subcontractors. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited. Historically, our costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and we accordingly believe the estimated fair value of liabilities under these agreements is immaterial. We warrant that our software products will perform in all material respects in accordance with our standard published specifications in effect at the time of delivery of the licensed products for a specified period of time. Additionally, we generally warrant that our consulting services will be performed consistent with generally accepted industry standards. In most cases, liability for these warranties is capped. If necessary, we would provide for the estimated cost of product and service warranties based on specific warranty claims and claim history; however, we have not incurred significant cost under our product or services warranties. As a result, we believe the estimated fair value of these liabilities is immaterial.
