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, 2013. 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, 2013 consolidated balance sheet included herein is derived from our audited consolidated financial statements.
	The results of operations for the six months ended March 29, 2014 are not necessarily indicative of the results expected for the remainder of the fiscal year.
	Recent Accounting Pronouncements
	Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists
	In July 2013, the Financial Accounting Standards Board (the FASB) issued Accounting Standards Update (ASU) 2013-11,
	Income Taxes (Topic 740)—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 generally requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, shall be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. ASU 2013-11 is effective for us in our first quarter of fiscal 2015. We are currently evaluating how ASU 2013-11 will impact 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-related amounts included in prepaid expenses and other current assets at March 29, 2014 and September 30, 2013 were $107.2 million and $108.6 million, respectively.
	Financing Receivables
	We periodically provide extended payment terms for software purchases to credit-worthy customers 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 a S&P bond rating of BBB- or above, we designate the customer as Tier 1. If a customer does not have a S&P bond rating, or has a 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 March 29, 2014 and September 30, 2013, amounts due from customers for contracts with original payment terms greater than twelve months (financing receivables) totaled $63.4 million and $53.1 million, respectively. Accounts receivable in the accompanying consolidated balance sheets included current receivables from such contracts totaling $46.7 million and $36.1 million at March 29, 2014 and September 30, 2013, respectively, and other assets in the accompanying consolidated balance sheets included long-term receivables from such contracts totaling $16.7 million and $17.0 million at March 29, 2014 and September 30, 2013, respectively. As of March 29, 2014, $0.3 million of these receivables were greater than 90 days past due. None of these receivables were past due as of September 30, 2013. Our credit risk assessment for financing receivables was as follows:
		March 29,		September 30,
		2014		2013
		(in thousands)
	S&P bond rating BBB-1 and above-Tier 1	$	44,246	$	42,189
	Internal Credit Assessment-Tier 2	19,174		10,934
	Internal Credit Assessment-Tier 3	—		—
	Total financing receivables	$	63,420	$	53,123
	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 March 29, 2014 and September 30, 2013, 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 six months ended March 29, 2014 and fiscal year 2013. 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 sold $12.0 million of financing receivables to third-party financial institutions in the six months ended March 29, 2014. There were no financing receivables sold to third-party financial institutions in the six months ended March 30, 2013.

	Restructuring Charges
	In the first six months of 2014, we recorded restructuring charges of $1.1 million, primarily associated with the completion of the restructuring actions initiated in the fourth quarter of 2013.
	In the first six months of 2013, as part of our strategy to reduce costs and enhance long term profitability, we restructured our business and recorded restructuring charges of $31.4 million. The restructuring charges included $29.9 million for severance and related costs associated with 288 employees notified of termination during the first six months of 2013 and $1.5 million of charges related to excess facilities.
	The following table summarizes restructuring accrual activity for the six months ended March 29, 2014:

Stock-Based Compensation	'
	Stock-based Compensation
	We measure the cost of employee services received in exchange for restricted stock and restricted stock unit (RSU) awards based on the fair value of our common stock 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.
	Our equity incentive plans are described more fully in Note K to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2013.

Substantially all other performance-based RSUs will be eligible to vest in three substantially equal installments in November 2014, 2015 and 2016 to the extent the applicable performance criteria have been achieved. RSUs not earned for a period may be earned in subsequent periods.

	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.

	RSUs totaling 0.2 million were outstanding during the first six months of 2014 but were not included in the calculation of diluted EPS because the share impact of the assumed proceeds related to the weighted unamortized compensation expense exceeded the weighted average RSUs outstanding. These RSUs were excluded from the computation of diluted EPS as the effect would have been anti-dilutive.
	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 authorized us to repurchase up to $100 million worth of shares with cash from operations in the period October 1, 2013 through September 30, 2014. In the second quarter and first six months of 2014, we repurchased 1.1 million shares at a cost of $40.0 million. In the second quarter and first six months of 2013, we repurchased 0.8 million shares and 1.5 million shares at a cost of $19.1 million and $34.9 million, respectively. All shares of our common stock repurchased are automatically restored to the status of authorized and unissued.

	Acquisition-related costs were $3.9 million and $5.2 million for the second quarter and first six months of 2014, respectively, and $2.1 million and $6.7 million for the second quarter and first six months of 2013, 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.

	On December 30, 2013, pursuant to an Agreement and Plan of Merger (the Merger Agreement), PTC Inc. acquired ThingWorx, Inc., creators of a platform for building and running applications for the Internet of Things (IoT), for $111.5 million in cash (net of cash acquired of $0.1 million) and $13.0 million representing the fair value of contingent consideration payable upon achievement of targets described below. We borrowed $110 million under our existing credit facility on December 27, 2013 to fund the acquisition.
	We acquired ThingWorx to accelerate our ability to support manufacturers as they create and service smart, connected products. At the time of the acquisition, ThingWorx had approximately 40 employees and historical annualized revenues were not material. The results of operations of ThingWorx have been included in our consolidated financial statements beginning on the acquisition date. Revenue and earnings of ThingWorx since the acquisition date were not material.
	The acquisition of ThingWorx has been accounted for as a business combination. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the December 30, 2013 acquisition date. The fair values of intangible assets were based on valuations using an income approach, with estimates and assumptions provided by management of ThingWorx and PTC. The process for estimating the fair values of identifiable intangible assets and the contingent consideration liability requires the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. The former shareholders of ThingWorx are eligible to receive additional consideration of up to $18.0 million, which is contingent on the achievement of certain profitability and bookings targets (as defined in the Merger Agreement) within the period from December 30, 2013 to January 1, 2016. If such targets are achieved, the consideration is payable in cash in two installments, up to half of which will become payable in fiscal 2015, after the first year measurement period, and the remainder of which, including any such amounts not earned in the first measurement period that are subsequently earned, will become payable in fiscal 2016 after the second year measurement period. In connection with accounting for the business combination, we recorded a liability of $13.0 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 financial targets. The estimated undiscounted range of outcomes for the contingent consideration is $0.0 million to $18.0 million. We will assess the probability that the targets will be met and at what level each reporting period. Any subsequent changes in the estimated fair value of the liability will be reflected in earnings until the liability is fully settled(activity in the second quarter of 2014 was $0.5 million, see Note 8).
	Based upon a valuation, the total purchase price allocation was as follows:
	Purchase price allocation:	(in thousands)
	Goodwill	$	102,190
	Identifiable intangible assets	32,100
	Cash	133
	Deferred tax assets and liabilities, net	(8,934		)
	Other assumed liabilities, net	(789		)
	Total allocation of purchase price consideration	124,700
	Less: cash acquired	(133		)
	Total purchase price allocation, net of cash acquired	$	124,567
	Less: contingent consideration	(13,048		)
	Net cash used to acquire ThingWorx	$	111,519
	The purchase price allocation resulted in $102.2 million of goodwill, the majority of which will not be deductible for income tax purposes. All of the acquired goodwill was allocated to our software products segment. Intangible assets of $32.1 million includes purchased software of $20.5 million, customer relationships of $8.8 million and trademarks of $2.3 million, which are being amortized over weighted average useful lives of 11 years, 9 years and 12 years, respectively, based upon the pattern in which economic benefits related to such assets are expected to be realized. Additionally, we recorded in process research and development (IPR&D) of $0.5 million related to a version of ThingWorx software planned to be released in the third quarter of 2014. The value of the IPR&D was determined using an income approach. In accounting for the business combination we recorded net deferred tax liabilities of $8.9 million, primarily related to the tax effect of the acquired intangible assets other than goodwill that are not deductible for income tax purposes and net operating loss carryforwards. As described in Note 11, these net deferred tax liabilities reduced our net deferred tax asset balance and resulted in a tax benefit to decrease our valuation allowance in the U.S.
	The resulting amount of goodwill reflects our expectations of the following benefits: (1) acceleration of our entry into the emerging IoT market including supporting manufacturers seeking to create and service smart, connected products and helping companies in a wide range of other industries seeking to develop applications for the IoT; (2) our intention to leverage our larger sales force and our intellectual property to attract new contracts and revenue; and (3) our intention to leverage our established presence in global markets.
	Servigistics
	On October 2, 2012, we acquired Servigistics, Inc., a developer of a suite of service lifecycle management (SLM) software solutions, for $220.8 million in cash (net of a final purchase price adjustment of $1.6 million received from the sellers in the the third quarter of 2013 and net of cash acquired of $1.4 million). We acquired Servigistics to expand our products that support service organizations within manufacturing companies, including managing service and spare parts information and the delivery of service for warranty and product support processes. Servigistics had annualized revenues of approximately $80 million and approximately 400 employees.
	The results of operations of Servigistics have been included in our consolidated financial statements beginning on the acquisition date. The unaudited financial information in the table below summarizes the combined results of operations of PTC and Servigistics, on a pro forma basis, as though the companies had been combined as of the beginning of PTC's fiscal year 2012. The pro forma information for all periods presented includes the effects of business combination accounting resulting from the acquisition as though the acquisition had been consummated as of the beginning of fiscal year 2012, including amortization charges from acquired intangible assets, the fair value adjustment of acquired deferred support revenue being recorded in fiscal year 2012 versus fiscal year 2013, the exclusion of $1.0 million and $5.6 million of acquisition-related costs in the second quarter and first six months of 2013, respectively, and the related tax effects. PTC's first quarter of 2013 results also exclude the $32.6 million tax benefit recorded to decrease our valuation allowance in jurisdictions where we have recorded a valuation allowance as a result of Servigistics' net deferred tax liability position recorded in accounting for the business combination (Note 11). The pro forma financial information is presented for comparative purposes only and is not necessarily indicative of the results of operations that actually would have been achieved if the acquisition had taken place at the beginning of 2012.

	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 consistent with our operating segments. As of March 29, 2014 and September 30, 2013, goodwill and acquired intangible assets in the aggregate attributable to our software products reportable segment were $1,087.6 million and $979.3 million, respectively, and attributable to our services reportable segment were $61.6 million and $62.9 million, respectively. We test 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. 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 completed our annual goodwill impairment review as of June 29, 2013 based on a qualitative assessment. Our qualitative assessment included company specific (financial performance and long-range plans), industry, and macroeconomic factors, as well as a sensitivity analysis of key model assumptions and consideration of the fair value of each reporting unit, which was approximately double its carrying value or higher, at the last valuation date. Based on our qualitative assessment, we believe it is more likely than not that the fair values of our reporting units exceed their carrying values and no further impairment testing is required.
	Goodwill and acquired intangible assets consisted of the following:

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 March 29, 2014 and September 30, 2013 were as follows:

	In connection with accounting for the ThingWorx business combination, we recorded a liability of $13.0 million representing the fair value of contingent consideration payable upon achievement of certain financial targets over the next two years. The liability that we recorded was valued using a discounted cash flow method and a probability weighted estimate of achievement of the financial targets based on inputs that are not observable in the market, which represents a level 3 measurement within the fair value hierarchy. Changes in the fair value of the contingent consideration liability will be reflected in acquisition-related charges in general and administrative expense until the liability is fully settled. The contingent consideration liability of $13.5 million is included in other liabilities in the consolidated balance sheet.

	Derivative Financial Instruments
	Our foreign currency risk management strategy is principally designed to mitigate the future potential financial impact of changes in the value of 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 with maturities of up to three months, to manage our exposure to fluctuations in foreign exchange rates that arise primarily from our foreign currency-denominated receivables and payables.
	Generally, we do not designate 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 March 29, 2014 and September 30, 2013, we had outstanding forward contracts with notional amounts equivalent to the following:

	Income Taxes
	In the second quarter and first six months of 2014, our effective tax rate was 10% on pre-tax income of $48.5 million and 18% on pre-tax income of $101.6 million, respectively, compared to a provision of 12% on pre-tax income of $19.4 million and a benefit of 68% on pre-tax income of $31.4 million in the second quarter and first six months of 2013, respectively. In the second quarter and first six months of 2014, 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 and the reversal of a portion of our valuation allowance against net deferred tax assets described below.
	In the second quarter and first six months of 2013, 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, and for the first six months of 2013 due primarily to the reversal of a portion of our valuation allowance against net deferred tax assets described below. Our tax provision for the second quarter and our tax benefit for the first six months of 2013 did not include a tax benefit on our forecast 2013 U.S. loss as it was offset by a valuation allowance established in the fourth quarter of 2012.  Additionally, in the second quarter of 2013, we recorded a $2.7 million tax benefit related to research and development (R&D) tax credits in the U.S triggered by a retroactive extension of the R&D credit enacted in the second quarter and a $3.2 million tax benefit related to final resolution of a long standing tax litigation and completion of a tax audit.
	In the fourth quarter of 2012, we recorded a $124.5 million non-cash charge to the income tax provision to establish a valuation allowance against all of our U.S. deferred tax assets. In the second quarter of 2014 and first quarter of 2013, our acquisitions of ThingWorx and Servigistics, Inc. were accounted for as business combinations. Assets acquired, including the fair values of acquired tangible assets, intangible assets (including finite-lived acquired intangible assets totaling $32.1 million for ThingWorx and $118.3 million for Servigistics) and assumed liabilities were recorded, and we recorded net deferred tax liabilities of $8.9 million and $35.6 million, respectively, primarily related to the tax effect of the acquired intangible assets that are not deductible for income tax purposes. These net deferred tax liabilities reduced our net deferred tax asset balance and resulted in a tax benefit of $8.9 million related to ThingWorx recorded in the second quarter of 2014 and $32.6 million related to Servigistics recorded in the first quarter of 2013 to decrease our valuation allowance in jurisdictions where we have recorded a valuation allowance (primarily the U.S.). As these decreases in the valuation allowance were not part of the accounting for the business combinations (the fair value of the assets acquired and liabilities assumed), they were recorded as income tax benefits.
	As of March 29, 2014 and September 30, 2013, we had unrecognized tax benefits of $14.7 million and $13.7 million, respectively. If all of our unrecognized tax benefits as of March 29, 2014 were to become recognizable in the future, we would record a benefit to the income tax provision of $13.7 million which would be partially offset by an increase in the U.S. valuation allowance of $7.3 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 $2 million as audits close and statutes of limitations expire.
	We follow the with-and-without approach for the direct effects of windfall tax deductions to determine the timing of the recognition of benefits for windfall tax deductions.  In the second quarter and first six months of 2014, we recorded windfall tax benefits of $1.3 million and $8.1 million to additional paid-in capital.

	Credit Agreement
	On January 30, 2014, we entered into a new credit facility with a syndicate of 13 banks for which JPMorgan Chase Bank, N.A. acts as Administrative Agent. We expect to use the credit facility for general corporate purposes, including acquisitions of businesses and working capital requirements. The credit facility consists of a $250 million term loan and a $750 million revolving loan commitment. The revolving loan commitment does not require amortization of principal. The term loan requires principal payments at the end of each calendar quarter. The revolving loan and term loan may be repaid in whole or in part prior to the scheduled maturity dates at PTC's option without penalty or premium. The credit facility matures on January 30, 2019, when all remaining amounts outstanding will be due and payable in full. We are required to make principal payments under the term loan of $9.375 million, $21.875 million, $25.0 million, $34.375 million, $37.5 million and $121.875 million in 2014, 2015, 2016, 2017, 2018 and 2019, respectively. We incurred costs of approximately $4 million in connection with entering into the new facility which will be amortized over the term of the new credit facility.
	As of March 29, 2014, we had $318.1 million outstanding under the credit facility, comprised of a $250.0 million term loan and $68.1 million of revolving loans. As of March 29, 2014, the fair value of our credit facility approximates our book value. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described in Note 8.
	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 of March 29, 2014, the annual rate on both the term loan and the revolving loans was 1.625%. A quarterly commitment fee on the undrawn portion of the credit facility is required, ranging from 0.175% to 0.25% per annum, based upon PTC’s leverage ratio.
	PTC is the sole borrower under the credit facility. The obligations under the credit facility are guaranteed by PTC’s material domestic subsidiaries, and 65% of the voting equity interests of PTC’s material first-tier foreign subsidiaries are pledged as collateral for the obligations.
	The credit facility limits PTC’s and its subsidiaries’ ability to, among other things: incur additional indebtedness; 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 $50 million for any purpose and an additional $75 million for acquisitions of businesses. In addition, under the credit facility, PTC and its subsidiaries must maintain the following financial ratios:
	•	a leverage ratio, defined as consolidated funded indebtedness to consolidated trailing four quarters EBITDA, of no greater than 3.00 to 1.00 at any time; 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 no less than 3.50 to 1.00 at any time.
	As of March 29, 2014, our leverage ratio was 0.98 to 1.00, our fixed charge coverage ratio was 22.20 to 1.00 and we were in compliance with all financial and operating covenants of the credit facility.

	Legal and Regulatory Matters
	China Investigation
	We have been cooperating to provide information to the U.S. Securities and Exchange Commission and the Department of Justice concerning payments and expenses by certain of our business partners in China and/or by employees of our Chinese subsidiary that raise questions concerning compliance with laws, including the U.S. Foreign Corrupt Practices Act. Our internal review is ongoing and now includes periods earlier than those previously examined. We continue to respond to requests for information from these agencies, including a subpoena issued to the company by the SEC. We cannot predict when or how this matter may be resolved. Resolution of this matter could include fines and penalties; however we are unable to estimate an amount that could be associated with any resolution and, accordingly, we have not recorded a liability for this matter. If resolution of this matter includes substantial fines or penalties, this could materially impact our results for the period in which the associated liability is recorded or such amounts are paid. Further, any settlement or other resolution of this matter could have collateral effects on our business in China, the United States and elsewhere.
	We terminated certain employees and business partners in China in connection with this matter, which may have an adverse impact on our level of sales in China. Revenue from China has historically represented 5% to 7% of our total revenue.
	Other Legal Proceedings
	We are subject to various 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 both 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 March 29, 2014, we had a legal proceedings and claims accrual of $1.0 million.
	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.

PTC's first quarter of 2013 results also exclude the $32.6 million tax benefit recorded to decrease our valuation allowance in jurisdictions where we have recorded a valuation allowance as a result of Servigistics' net deferred tax liability position recorded in accounting for the business combination (Note 11).
