	2. Summary of Significant Accounting Policies
	Consolidation
	The unaudited consolidated financial statements include the accounts of Tornier N.V. and all of its wholly and majority owned subsidiaries. In consolidation, all material intercompany accounts and transactions are eliminated.
	The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S.) for interim financial information and the instructions to quarterly report on Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) have been condensed or omitted pursuant to these rules and regulations. Accordingly, these unaudited consolidated interim financial statements should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 30, 2012, as filed with the U.S. Securities and Exchange Commission (SEC).
	Basis of Presentation
	The Company’s fiscal quarters are generally determined on a 13-week basis and always end on a Sunday. As a result, the Company’s fiscal year is generally 364 days and ends on the Sunday nearest to December 31. Every few years, it is necessary to add an extra week to a quarter to make it a 14-week period in order to have the year-end fall on the Sunday nearest to December 31. The third quarters of 2013 and 2012 each consisted of 13 weeks.
	In the opinion of the Company’s management, the unaudited interim financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, consisting of normal recurring accruals, necessary for the fair presentation of the Company’s interim results. The results of operations for any interim period are not indicative of results for the full fiscal year.
	All amounts are presented in U.S. Dollar (“$”), except where expressly stated as being in other currencies, e.g. Euros (“€”).
	Recent Accounting Pronouncement
	The Company adopted Accounting Standards Update (ASU) 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 amended Accounting Standards Codification (ASC) 220 to require companies to report, in one place, information about reclassifications out of accumulated other comprehensive income (AOCI). The ASU allows companies to present this information on the face of the financial statements, if certain requirements are met. Otherwise, the information must be presented in the notes. The ASU requires information about the effect (i.e., amount) of significant reclassification items on the line items of net income by component of other comprehensive income (OCI). In addition, the ASU requires detailed reporting about changes in AOCI balances. It requires companies to present details of current-period changes in AOCI on the face of the financial statements or in the notes. The adoption of this standard did not have a material impact for the Company in the first nine months of 2013.
	In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes” (“ASU No. 2013-11”). ASU No. 2013-11 requires companies to present unrecognized tax benefits as a reduction of the deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, if net settlement is required or expected. To the extent that net settlement is not required or expected, the unrecognized tax benefit must be presented as a liability. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. ASU No. 2013-11 is effective for reporting periods beginning after December 15, 2013, and should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Because this standard only affects the presentation of unrecognized tax benefits and not the measurement of an unrecognized tax benefit, the Company expects this standard will not have a material impact on its consolidated financial statements.

Business Combination	'
	3. Business Combination
	On October 4, 2012, the Company completed the acquisition of 100% of the outstanding capital stock of OrthoHelix Surgical Designs, Inc. (OrthoHelix). OrthoHelix is a company that is focused on developing and marketing specialty implantable screw and plate systems for the repair of small bone fractures and deformities predominantly in the foot and ankle. Under the terms of the agreement, the Company acquired the assets and assumed certain liabilities of OrthoHelix for an aggregate purchase price of $152.6 million, including $100.4 million in cash, the equivalent of $38.0 million in Tornier ordinary shares based on the closing share price on the date of acquisition, and $14.2 million related to the fair value of additional contingent consideration of up to $20.0 million. The contingent consideration is payable in future periods based on growth of the Company’s lower extremity joints and trauma revenue category in fiscal years 2013 and 2014.
	The OrthoHelix acquisition was accounted for as an acquisition of a business; and, accordingly, the results have been included in the Company’s consolidated results of operations from the date of acquisition. The allocation of the total purchase price to the net tangible and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The excess of the purchase price over the identifiable intangible and net tangible assets in the amount of $105.8 million was allocated to goodwill, which is not deductible for tax purposes. Qualitatively, the three largest components of goodwill include: (1) expansion into international markets; (2) the relationships between the Company’s sales representatives and physicians; and (3) the development of new product lines and technology. During the first quarter of 2013, the Company finalized the purchase accounting for this transaction and recorded minor adjustments to accounts receivable and goodwill.
	The following represents the allocation of the purchase price, along with the estimated useful lives of the identified intangible assets:
		Purchase price			Estimated useful
		allocation			life
		(in thousands)
	Goodwill	$	105,791
	Other intangible assets
	Developed technology	$	35,500			10
	In-process research and development		3,500			N/A
	Trademarks and trade names		1,500			3
	Non-compete agreements		100			3
	Tangible assets acquired and liabilities assumed:
	Accounts receivable		4,443
	Inventory		12,033
	Other assets		776
	Instruments, net		4,475
	Accounts payable and accrued liabilities		(3,606	)
	Deferred income taxes		(11,900	)
	Other long-term debt		(16	)
	Total purchase price	$	152,596
	The Company’s acquisition of OrthoHelix involves the potential for the payment of future contingent consideration upon the achievement of certain product revenue growth milestones. Contingent consideration is recorded at the estimated fair value of the contingent milestone payments on the acquisition date. The fair value of the contingent milestone consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within operating expenses in the consolidated statements of operations.
	At September 29, 2013, the fair value of the contingent consideration was $10.3 million and was determined based on a discounted cash flow analysis that included revenue estimates and a discount rate, which are considered significant unobservable inputs. The revenue estimates were based on current management expectations for the business and the discount rate used as of September 29, 2013 was 7.5% based on the Company’s estimated weighted average cost of capital.
	Pro forma results of operations (unaudited) of the Company for the nine months ended September 30, 2012, as if the acquisition had occurred on January 2, 2012, are as follows:
		Nine months ended
		September 30,
		2012
	Revenue	$	219,017
	Net loss		(25,011	)
	Basic and diluted net loss per share	$	(0.60	)
	The pro forma results of operations are not necessarily indicative of future operating results. Included in the consolidated statement of operations for the nine months ended September 29, 2013 is approximately $24.5 million of revenue and $0.7 million of net loss related to OrthoHelix.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	4. Fair Value of Financial Instruments
	The Company applies ASC Topic 820, which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. The Company measures certain assets and liabilities at fair value on a recurring or non-recurring basis. U.S. GAAP requires fair value measurements to be classified and disclosed in one of the following three categories:
	Level 1—Assets and liabilities with unadjusted, quoted prices listed on active market exchanges.
	Level 2—Assets and liabilities determined using prices for recently traded assets and liabilities with similar underlying terms, as well as directly or indirectly observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.
	Level 3—Assets and liabilities that are not actively traded on a market exchange. This category includes situations where there is little, if any, market activity for the asset or liability. The prices are determined using significant unobservable inputs or valuation techniques.
	A summary of the financial assets and liabilities that are measured at fair value on a recurring basis at September 29, 2013 and December 30, 2012 are as follows:
		29-Sep-13			Quoted Prices in		Significant		Significant
					Active Markets		Other		Unobservable
					(Level 1)		Observable		Inputs (Level 3)

	As of September 29, 2013 and December 30, 2012, the Company had a derivative asset with a fair value of $0.1 million and $0.3 million, respectively, with recurring Level 2 fair value measurements. The derivatives are foreign exchange forward contracts and their fair values are based on pricing for similar recently executed transactions. The contracts were first entered into in 2012. The amount of gain (loss) recognized in foreign exchange gain (loss) for the nine months ended September 29, 2013 and September 30, 2012 related to this derivative is approximately $0.1 million and $(0.1) million, respectively. Included in Level 3 fair value measurements as of September 29, 2013 are the following: a $0.5 million contingent consideration liability related to potential earn-out payments for the acquisition of the Company’s exclusive distributor in Belgium and Luxembourg that was completed in May 2012, a $10.3 million contingent consideration liability related to potential earn-out payments for the acquisition of OrthoHelix that was completed in October 2012, and a $1.4 million contingent consideration liability related to earn-out payments for distributor acquisitions in the United States that occurred throughout the first nine months of 2013. Earn-out liabilities are carried at fair value and included in contingent consideration (short term and long term) on the consolidated balance sheet. The earn-out liabilities related to the Company’s distributor in Belgium and Luxembourg, OrthoHelix, and the U.S. distributors were determined based on discounted cash flow analyses that included revenue estimates and a discount rate, which are considered significant unobservable inputs as of September 29, 2013. The revenue estimates were based on current management expectations for these businesses and the discount rate used was between 8-14% and was based on the Company’s estimated weighted average cost of capital as adjusted for each transaction. To the extent that these assumptions were to change, the fair value of the contingent consideration liabilities could change significantly. Included in interest expense on the consolidated statement of operations for the nine months ended September 29, 2013 is $0.8 million related to the accretion of the contingent consideration. There were no transfers between levels during the nine months ended September 29, 2013.
	Included in Level 3 fair value measurements as of December 30, 2012 is a $0.7 million contingent consideration liability related to potential earn-out payments for the acquisition of the Company’s exclusive distributor in Belgium and Luxembourg that was completed in May 2012 and a $14.5 million contingent consideration liability related to potential earn-out payments for the acquisition of OrthoHelix that was completed in October 2012. The contingent consideration liabilities are carried at fair value, which is determined based on a discounted cash flow analysis that included revenue estimates and a discount rate, which are considered significant unobservable inputs as of December 30, 2012. The revenue estimates were based on then current management expectations for these businesses and the discount rate used as of December 30, 2012 was 8% and was based on the Company’s estimated weighted average cost of capital. Included in interest expense on the consolidated statement of operations for the nine months ended September 30, 2012 is $0.1 million related to the accretion of the contingent consideration. There were no transfers between levels during the nine months ended September 29, 2013.
	The Company also has certain assets and liabilities that are measured at fair value on a non-recurring basis. The Company reviews the carrying amount of its long-lived assets other than goodwill for potential impairment whenever events or changes in circumstances indicate that their carrying values may not be recoverable. During the quarters ended September 29, 2013 and September 30, 2012, the Company recognized no impairments. During 2012, the Company initiated and completed a facilities consolidation initiative that included the termination of certain facility leases. The termination liability for these leases was determined using a discounted cash flow analysis that included a discount rate assumption, which is based on the credit adjusted risk free interest rate input, and an assumption related to the timing and amount of sublease income. The timing of the sublease income is a significant unobservable input and thus is considered a Level 3 fair value measurement. As of September 29, 2013, the value of this liability was approximately $0.4 million.
	As of September 29, 2013, the Company had short-term and long-term debt of $67.3 million, the vast majority of which was variable rate debt. The fair value of the Company’s debt obligations approximates carrying value as a result of its variable rate term and is considered a Level 2 fair value measurement.

	Line of Credit
	On October 4, 2012, the Company and its U.S. operating subsidiary, Tornier, Inc. (Tornier USA), entered into a credit agreement with Bank of America, N.A., as Administrative Agent, SG Americas Securities, LLC, as Syndication Agent, BMO Capital Markets and JPMorgan Chase Bank, N.A., as Co-Documentation Agents, Merrill Lynch, Pierce, Fenner & Smith Incorporated and SG Americas Securities, LLC, as Joint Lead Arrangers and Joint Bookrunners, and the other lenders party thereto. The credit agreement includes a senior secured revolving credit facility denominated at the election of Tornier USA, in U.S. dollars, Euros, pounds, sterling and yen in an aggregate principal amount of up to the U.S. dollar equivalent of $30.0 million. Funds available under the revolving credit facility may be used for general corporate purposes. Loans under the revolving credit facility bear interest at (a) the alternate base rate (if denominated in U.S. dollars), equal to the greatest of (i) the prime rate in effect on such day, (ii) the federal funds rate in effect on such day plus 1/2 of 1%, and (iii) the adjusted LIBO rate plus 1%, plus in the case of each of (i)-(iii) above, an applicable rate of 2.00% or 2.25% (depending on the Company’s total net leverage ratio as defined in the Company’s credit agreement), or (b) the applicable adjusted LIBO rate for the relevant interest period plus an applicable rate of 3.00% or 3.25% (depending on the Company’s total net leverage ratio), plus the mandatory cost (as defined in the Company’s credit agreement) if such loan is made in a currency other than U.S. dollars or from a lending office in the United Kingdom or a participating member state (as defined in the Company’s credit agreement). There was no outstanding amount under the line of credit as of September 29, 2013. As of December 30, 2012, the outstanding balance related to this line of credit was $1.0 million. The term of the line of credit ends in October 2017.
	Mortgages
	The Company has a mortgage secured by an office building in Grenoble, France. This mortgage had an outstanding balance of $3.3 million and $3.7 million at September 29, 2013 and December 30, 2012, respectively. This mortgage bears a fixed annual interest rate of 4.9%.
	Bank Term Debt
	In addition to the senior secured revolving credit facility discussed above, the credit agreement entered into on October 4, 2012 also provided for an aggregate credit commitment to Tornier USA of $115.0 million of term debt, consisting of: (1) a senior secured term loan facility to Tornier USA denominated in U.S. dollars in an aggregate principal amount of up to $75.0 million; and (2) a senior secured term loan facility to Tornier USA denominated in Euros in an aggregate principal amount of up to the U.S. dollar equivalent of $40.0 million. The borrowings under the term loan facilities were used to pay the cash consideration for the OrthoHelix acquisition, fees, costs and expenses incurred in connection with the acquisition and the credit agreement, and to repay prior existing indebtedness of the Company and its subsidiaries. The term debt matures in October 2017. In the second quarter of 2013, the $40.0 million senior secured term loan facility denominated in Euros was repaid in full. As part of the repayment, the Company recorded a $1.1 million loss on extinguishment of debt related to the write-off of the corresponding deferred financing costs. Additionally, in June 2013, the Company repaid $10.5 million of the senior secured U.S. dollar denominated loan.
	Borrowings under the senior secured term loan facilities within the credit agreement as of September 29, 2013 and December 30, 2012 were as follows:
		September 29,			December 30,
		2013			2012
	Senior secured U.S. dollar term loan	$	64,031		$	75,000
	Senior secured Euro term loan		—			40,772
	Deferred financing costs		(3,367	)		(5,138	)
	Total	$	60,664		$	110,634
	The U.S. dollar denominated term facility bears interest at (a) the alternate base rate (if denominated in U.S. dollars), equal to the greatest of (i) the prime rate in effect on such day, (ii) the federal funds rate in effect on such day plus 1/2 of 1%, and (iii) the adjusted LIBO rate, with a floor of 1% (as defined in the Company’s new credit agreement) plus 1%, plus in the case of each of (i)-(iii) above, an applicable rate of 2.00% or 2.25% (depending on the Company’s total net leverage ratio as defined in the credit agreement), or (b) in the case of a eurocurrency loan (as defined in the Company’s credit agreement), at the applicable adjusted LIBO rate for the relevant interest period, with a floor of 1%, plus an applicable rate of 3.00% or 3.25% (depending on the Company’s total net leverage ratio), plus the mandatory cost (as defined in the Company’s credit agreement) if such loan is made in a currency other than U.S. dollars or from a lending office in the United Kingdom or a participating member state (as defined in the Company’s credit agreement). Under the Euro denominated term facility, (a) alternate base rate loans bear interest at the alternate base rate plus the applicable rate, which was 3.00% or 3.25% (depending on the Company’s total net leverage ratio) and (b) eurocurrency loans bear interest at the adjusted LIBO rate for the relevant interest period, with a floor of 1%, plus an applicable rate, which was 4.00% or 4.25% (depending on the Company’s total net leverage ratio), plus the mandatory cost, if applicable.
	The credit agreement, including the term loan and the revolving line of credit, contains customary covenants, including financial covenants which require the Company to maintain a minimum interest coverage ratio, annual capital expenditure limits and a maximum total net leverage ratio, and customary events of default. The obligations under the credit agreement are guaranteed by the Company, Tornier USA and certain other specified subsidiaries of the Company, and, subject to certain exceptions, are secured by a first priority security interest in substantially all of the assets of the Company and certain specified existing and future subsidiaries of the Company. The Company was in compliance with all covenants as of September 29, 2013.
	The Company’s international subsidiaries had other long-term secured and unsecured notes totaling $1.3 million at December 30, 2012, with initial maturities ranging from three to ten years. A portion of these notes have fixed annual interest rates that range from 3.7% to 8.5%.
	Also included in term debt is $1.1 million and $1.5 million related to capital leases at September 29, 2013 and December 30, 2012, respectively.
	Shareholder Debt
	In 2008, one of the Company’s 51%-owned and consolidated subsidiaries borrowed $2.2 million from a member of the Company’s board of directors who is also a 49% owner of the consolidated subsidiary. This loan was used to partially fund the purchase of real estate in Grenoble, France, to be used as a manufacturing facility. Interest on the debt is variable based on three-month Euro plus 0.5%. The outstanding balance on this debt was $2.3 million and $2.2 million at September 29, 2013 and December 30, 2012, respectively. The non-controlling interest in this subsidiary is deemed immaterial to the consolidated financial statements.

Share-Based Compensation	'
	10. Share-Based Compensation
	Share-based awards are granted under the Tornier N.V. 2010 Incentive Plan, as amended. This plan allows for the issuance of up to a maximum of 7.7 million ordinary shares in connection with the grant of share-based awards, including stock options, stock grants, stock appreciation rights and other types of awards as deemed appropriate. To date, only options to purchase ordinary shares (options) and stock grants in the form of restricted stock units (RSUs) have been awarded under the plan. Both types of awards generally have graded vesting periods of four years and the options generally expire ten years after the grant date. Options are granted with exercise prices equal to the fair value of the Company’s ordinary shares on the date of grant.
	The Company recognizes compensation expense for these awards on a straight-line basis over the vesting period. Share-based compensation expense is included in cost of goods sold, selling, general and administrative expense, and research and development expense on the consolidated statements of operations.
	Below is a summary of the allocation of share-based compensation (in thousands):
		Three months ended					Nine months ended

	During the nine months ended September 29, 2013, the Company granted 630,739 options to purchase ordinary shares to employees at a weighted average exercise price of $19.37 per share and a weighted average fair value of $8.97 per share. During the nine months ended September 30, 2012, the Company granted 512,610 options to purchase ordinary shares to employees at a weighted average exercise price of $18.73 per share and a weighted average fair value of $8.70 per share. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model using the following weighted-average assumptions:
		Nine months

Income Taxes	'
	11. Income Taxes
	The Company’s effective tax rate for the nine months ended September 29, 2013 was 5.8%. During the nine months ended September 29, 2013, the Company recognized $1.4 million of income tax expense on pre-tax losses of $24.3 million. Given the Company’s history of operating losses, the Company does not generally recognize a provision for income taxes in the United States and certain of the Company’s European sales offices because it has established a valuation allowance for substantially all of the net deferred tax assets in these jurisdictions. The Company records tax expense or benefit in certain other European jurisdictions. The mix of pre-tax income or loss in these jurisdictions as well as in the jurisdictions in which valuation allowances are established are the primary drivers of the Company’s effective tax rate. The Company recognized $1.5 million of tax expense in certain of its European jurisdictions during the nine months ended September 29, 2013, but this was offset by a tax benefit of $0.1 million recognized from the reversal of valuation allowance in the United States due to the recognition of deferred tax liabilities related to certain formerly indefinite lived intangible assets that were reclassified to definite lived intangibles during the period. Included in the $1.5 million of tax expense from European jurisdictions is $1.0 million of income tax expense to establish a valuation allowance for deferred tax assets related to foreign stock compensation during the third quarter of 2013. The Company determined the tax planning strategies necessary to realize these deferred tax assets was no longer prudent and as a result the Company no longer believes these deferred tax assets are realizable.
	The Company operates in multiple income tax jurisdictions both inside and outside the United States. Income tax authorities in these jurisdictions regularly perform audits of the Company’s income tax filings. Accordingly, management must determine the appropriate allocation of income to each of these jurisdictions based on current interpretations of complex income tax regulations. Income tax audits associated with the allocation of this income and other complex issues, including inventory transfer pricing and cost sharing, product royalty and foreign branch arrangements, may require an extended period of time to resolve and may result in significant income tax adjustments if changes to the income allocation are required between jurisdictions with different income tax rates.

	On May 15, 2013, the Company completed an underwritten public offering of 8.1 million ordinary shares at a public offering price of $16.15 per ordinary share. Pursuant to this offering, the Company sold 5.2 million shares and certain shareholders sold 2.9 million shares, both of which were inclusive of the exercise of the underwriters’ over-allotment option. The Company received $78.9 million in net proceeds from the offering, net of the underwriters’ discount and commissions and offering expenses. The Company used approximately $50.5 million of the net proceeds to repay its $40.0 million Euro-denominated term loan and a portion of its U.S.-dollar denominated term loan. The Company intends to use the remaining net proceeds for working capital and general corporate purposes.
	The Company had 48.4 million and 41.7 million ordinary shares issued and outstanding as of September 29, 2013 and December 30, 2012, respectively.
	The Company had options to purchase ordinary shares and RSUs outstanding of an aggregate 3.4 million and 4.2 million at September 29, 2013 and December 30, 2012, respectively. None of the options or RSUs were included in diluted earnings per share for the nine months ended September 29, 2013 and December 30, 2012, respectively, because the Company recorded a net loss in all periods; and therefore, including these instruments would be anti-dilutive.

Litigation	'
	14. Litigation
	From time to time, the Company is subject to various pending or threatened legal actions and proceedings, including those that arise in the ordinary course of our business. These actions and proceedings may relate to, among other things, product liability, intellectual property, distributor, commercial and other matters. Such matters are subject to many uncertainties and to outcomes that are not predictable with assurance and that may not be known for extended periods of time. The Company records a liability in its consolidated financial statements for costs related to claims, including future legal costs, settlements and judgments, where the Company has assessed that a loss is probable and an amount can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that material loss may be have been incurred. In the opinion of management, the amount of liability, if any, with respect to these matters, individually or in the aggregate, will not materially affect the Company’s consolidated results of operations, financial position or cash flows.
	On October 25, 2007, two of the Company’s former sales agents filed a complaint in the U.S. District Court for the Southern District of Illinois, alleging that the Company had breached their agency agreements and committed fraudulent and negligent misrepresentations. At a court-mandated settlement conference on June 7, 2013, the Company settled with each of the parties individually pursuant to which the Company agreed to make a cash payment to each of the two plaintiffs. On that same day, the court issued an order dismissing the case with prejudice effective as of August 9, 2013.

Consolidation	'
	Consolidation
	The unaudited consolidated financial statements include the accounts of Tornier N.V. and all of its wholly and majority owned subsidiaries. In consolidation, all material intercompany accounts and transactions are eliminated.
	The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S.) for interim financial information and the instructions to quarterly report on Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) have been condensed or omitted pursuant to these rules and regulations. Accordingly, these unaudited consolidated interim financial statements should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 30, 2012, as filed with the U.S. Securities and Exchange Commission (SEC).
Basis of Presentation	'
	Basis of Presentation
	The Company’s fiscal quarters are generally determined on a 13-week basis and always end on a Sunday. As a result, the Company’s fiscal year is generally 364 days and ends on the Sunday nearest to December 31. Every few years, it is necessary to add an extra week to a quarter to make it a 14-week period in order to have the year-end fall on the Sunday nearest to December 31. The third quarters of 2013 and 2012 each consisted of 13 weeks.
	In the opinion of the Company’s management, the unaudited interim financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, consisting of normal recurring accruals, necessary for the fair presentation of the Company’s interim results. The results of operations for any interim period are not indicative of results for the full fiscal year.
	All amounts are presented in U.S. Dollar (“$”), except where expressly stated as being in other currencies, e.g. Euros (“€”).
Recent Accounting Pronouncement	'
	Recent Accounting Pronouncement
	The Company adopted Accounting Standards Update (ASU) 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 amended Accounting Standards Codification (ASC) 220 to require companies to report, in one place, information about reclassifications out of accumulated other comprehensive income (AOCI). The ASU allows companies to present this information on the face of the financial statements, if certain requirements are met. Otherwise, the information must be presented in the notes. The ASU requires information about the effect (i.e., amount) of significant reclassification items on the line items of net income by component of other comprehensive income (OCI). In addition, the ASU requires detailed reporting about changes in AOCI balances. It requires companies to present details of current-period changes in AOCI on the face of the financial statements or in the notes. The adoption of this standard did not have a material impact for the Company in the first nine months of 2013.
	In July 2013, the FASB issued ASU No. 2013-11, “Income Taxes” (“ASU No. 2013-11”). ASU No. 2013-11 requires companies to present unrecognized tax benefits as a reduction of the deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, if net settlement is required or expected. To the extent that net settlement is not required or expected, the unrecognized tax benefit must be presented as a liability. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. ASU No. 2013-11 is effective for reporting periods beginning after December 15, 2013, and should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Because this standard only affects the presentation of unrecognized tax benefits and not the measurement of an unrecognized tax benefit, the Company expects this standard will not have a material impact on its consolidated financial statements.
