| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared by Align Technology, Inc. (“we”, “our”, or “Align”) in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and contain all adjustments, including normal recurring adjustments, necessary to present fairly our results of operations for the three months ended March 31, 2014 and 2013, our comprehensive income (loss) for the three months ended March 31, 2014 and 2013, our financial position as of March 31, 2014 and our cash flows for the three months ended March 31, 2014 and 2013. The Condensed Consolidated Balance Sheet as of December 31, 2013 was derived from the December 31, 2013 audited financial statements. Net revenues by geographic area for prior period amounts in Note 12 have been reclassified to conform with the current period presentation. These reclassifications had no impact on our financial position for the three months ended March 31, 2014 and 2013. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or any other future period, and we make no representations related thereto. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk” and the Consolidated Financial Statements and notes thereto included in Items 7, 7A and 8, respectively, in our Annual Report on Form 10-K for the year ended December 31, 2013. Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles ("GAAP") in the United States of America (“U.S.”) requires our management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, we evaluate our estimates, including those related to the fair values of financial instruments, long-lived assets and goodwill, useful lives of intangible assets and property and equipment, stock-based compensation, income taxes, and contingent liabilities, among others. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Recent Accounting Pronouncements In July 2013, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-11, "Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force)." The amendments in this ASU provide guidance on the financial statements presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. An unrecognized tax benefit should 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 with certain exceptions, in which case such an unrecognized tax benefit should be presented in the financial statements as a liability. The amendments in this ASU do not require new recurring disclosures and are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this standard in the first quarter of 2014 had the effect of reducing our accruals for uncertain tax positions by $8.4 million, with an offsetting reduction in our long term deferred tax assets, but had no effect on net income. |

| Marketable Securities and Fair Value Measurements | Marketable Securities and Fair Value Measurements As of March 31, 2014 and December 31, 2013, the estimated fair value of our short-term and long-term marketable securities, classified as available for sale, are as follows (in thousands): Short-term
Long-term
Short-term
Long-term
For the three months ended March 31, 2014 and 2013, realized gains were immaterial. Unrealized gains and losses for our available for sale securities as of March 31, 2014 and December 31, 2013 were also immaterial. Cash and cash equivalents are not included in the table above as the gross unrealized gains and losses are not material. We have no material short-term or long-term investments that have been in a continuous unrealized loss position for greater than twelve months as of March 31, 2014 and December 31, 2013. Amounts reclassified to earnings from accumulated other comprehensive income related to unrealized gain or losses were immaterial for the three months ended March 31, 2014 and 2013. Our fixed-income securities investment portfolio consists of corporate bonds, U.S. dollar dominated foreign corporate bonds, commercial paper, municipal securities, U.S. government agency bonds and asset-backed securities that have a maximum maturity of two years. The securities that we invest in are generally deemed to be low risk based on their credit ratings from the major rating agencies. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As interest rates increase, those securities purchased at a lower yield show a mark-to-market unrealized loss. The unrealized losses are due primarily to changes in credit spreads and interest rates. We expect to realize the full value of all these investments upon maturity or sale. The weighted average remaining duration of these securities was approximately 11 months and 10 months as of March 31, 2014 and December 31, 2013, respectively. As the carrying value approximates the fair value for our short-term and long-term marketable securities shown in the tables above, the following table summarizes the fair value of our short-term and long-term marketable securities classified by maturity as of March 31, 2014 and December 31, 2013 (in thousands):
Fair Value Measurements We measure the fair value of our cash equivalents and marketable securities 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. We use the GAAP fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value: Level 1 — Quoted (unadjusted) prices in active markets for identical assets or liabilities. Our Level 1 assets consist of money market funds and U.S. government treasury bonds. We did not hold any Level 1 liabilities as of March 31, 2014 or December 31, 2013. Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets, 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 asset or liability. Our Level 2 assets consist of commercial paper, corporate bonds, U.S. dollar dominated foreign corporate bonds, U.S. government agency bonds, municipal securities, asset-backed securities, U.S. government treasury bonds and our Israeli funds that are mainly invested in insurance policies. We obtain fair values for Level 2 investments from our asset manager for each of our portfolios. Our custody bank and asset managers independently use professional pricing services to gather pricing data which may include quoted market prices for identical or comparable financial instruments, or inputs other than quoted prices that are observable either directly or indirectly, and we are ultimately responsible for these underlying estimates. We did not hold any Level 2 liabilities as of March 31, 2014 or December 31, 2013. Level 3 — Unobservable inputs to the valuation methodology that are supported by little or no market activity and that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation. We did not hold any Level 3 assets or liabilities as of March 31, 2014 or December 31, 2013. Non-Recurring Fair Value Measurements During the three months ended March 31, 2013, we recorded an impairment charge to our long-lived assets and goodwill of $26.3 million and $40.7 million, respectively, related to our Scanner and Services ("Scanner") reporting unit, formerly referred to as Scanner and CAD/CAM Services ("SCCS"), as an event occurred and circumstances changed that led us to perform an impairment analysis prior to our annual test which required us to determine the fair value of the Scanner reporting unit (Refer to Note 5). These fair value measurements were calculated using unobservable inputs, using the income approach which is classified as Level 3 within the fair value hierarchy. Inputs for the income approach includes the amount and timing of future cash flows based on our most recent operational budgets, strategic plans, terminal growth rates assumptions and other estimates. Recurring Fair Value Measurements The following table summarizes our financial assets measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013 (in thousands):

| Business Combinations [Abstract] | |
| Business Combination Disclosure | Business Combinations On April 30, 2013, we completed the acquisition of ICA Holdings Pty Limited ("ICA") upon the expiration of the distribution agreement between certain subsidiaries of ICA and Align Technology B.V., for a total cash consideration of approximately $8.6 million, of which $7.4 million was attributed to assets acquired, $2.4 million in liabilities assumed and $3.6 million to goodwill. Goodwill as a result of this acquisition represents the excess of the purchase price over the fair value of the underlying net assets acquired and represents the knowledge and experience of the workforce in place. None of this goodwill will be deductible for tax purposes. Under the applicable accounting guidance, goodwill will not be amortized but will be tested for impairment on an annual basis or more frequently if certain indicators are present. We believe that the transition from our distributor arrangement to a direct sales model as a result of the acquisition of ICA will increase our net revenues in the region as we will experience higher average selling price(s) (“ASP”) as compared to our discounted ASP under the prior distribution agreement. Pro forma results of operations for this acquisition have not been presented as it is not material to our results of operations, either individually or in aggregate, for the three months ended March 31, 2013. |

| Goodwill and Acquired Intangible Assets | Goodwill and Long-lived Assets Goodwill The change in the carrying value of goodwill for the three months ended March 31, 2014 by our reportable segments, which are also our reporting units, is as follows (in thousands):
1 The adjustments to goodwill during the three months ended March 31, 2014 were due to foreign currency translation. The goodwill balance is entirely attributable to our Clear Aligner reporting unit. During the fourth quarter of fiscal 2013, we performed the annual goodwill impairment testing and found no impairment events as the fair value of our Clear Aligner reporting unit was significantly in excess of the carrying value. Impairment of Goodwill in 2013 We evaluate our goodwill for impairment at least annually on November 30th or more frequently if indicators are present, an event occurs or circumstances change that suggest an impairment may exist and that it would more likely than not reduce the fair value of the reporting unit below its carrying amount. During March 2013, changes in the competitive environment for intra-oral scanners, including announcements from our competitors of new low-priced scanners targeted at orthodontists and general practitioner dentists in North America, that caused us to lower our expectations for growth and profitability for our Scanner reporting unit. As a result, we determined that goodwill related only to our Scanner reporting unit should be tested for impairment as of March 2013 due to these facts and circumstances which would more likely than not reduce the fair value of our Scanner reporting unit below its carrying amount. There was no triggering event related to our Clear Aligner goodwill. We performed a step one analysis for our Scanner reporting unit which consists of a comparison of the fair value of the Scanner reporting unit against its carrying amount, including the goodwill allocated to it. In deriving the fair value of the Scanner reporting unit, we utilized the income approach which is classified as Level 3 within the fair value hierarchy. This approach provides an estimated fair value based on discounted expected future cash flows, which are based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rate used is based on a weighted average cost of capital adjusted for the relevant risk associated with the characteristics of the business and the projected cash flows. As a result of our step one analysis, we concluded that the fair value of the Scanner reporting unit was less than its carrying value; therefore, we proceeded to step two of the goodwill impairment analysis. Step two of the goodwill impairment analysis measures the impairment charge by allocating the reporting unit's fair value to all of the assets and liabilities of the reporting unit in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the reporting unit was being acquired in a business combination. This allocation process was performed only for the purposes of measuring the goodwill impairment and not to adjust the carrying values of the recognized tangible assets and liabilities. Any excess of the carrying value of the reporting unit's goodwill over the implied fair value of the reporting unit's goodwill is recorded as an impairment loss. We use a discounted cash flow ("DCF") approach, utilizing the harvest model, to estimate the fair value of a reporting unit which we believe is the most reliable indicator of fair value of this business, and is most consistent with the approach a market place participant would use. Based on our analysis, there was no implied goodwill for the Scanner reporting unit; therefore, we recorded a goodwill impairment charge of $40.7 million in the three months ended March 31, 2013, which represents the remaining goodwill balance in the Scanner reporting unit. None of the goodwill impairment charge was deductible for tax purposes. Long-lived Assets Impairment of Long-lived Assets in 2013 We amortize our intangible assets over their estimated useful lives. We evaluate long-lived assets, which includes property, plant and equipment and intangible assets, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The carrying value is not recoverable if it exceeds the undiscounted cash flows resulting from the use of the asset and its eventual disposition. Our estimates of future cash flows attributable to our long-lived assets require significant judgment based on our historical and anticipated results and are subject to many factors. Factors we consider important which could trigger an impairment review include significant negative industry or economic trends, significant loss of customers and changes in the competitive environment of our intra-oral scanning business. During March 2013, changes in the competitive environment for intra-oral scanners, including announcements from our competitors of new low-priced scanners targeted at orthodontists and general practitioner dentists in North America, that caused us to lower our expectations for growth and profitability for our Scanner reporting unit. As a result, we determined that the carrying value of the Scanner long-lived assets was not recoverable as compared to the value of the undiscounted cash flows of our revised projections for the asset group. In order to determine the impairment amount of our long-lived assets, we fair valued each key component of our long-lived assets within the asset group, which involved the use of significant estimates and assumptions including replacement costs, revenue growth rates, operating margins, and plant and equipment cost trends. We use a DCF approach, utilizing the harvest model, to estimate the fair value of a reporting unit which we believe is the most reliable indicator of fair value of this business, and is most consistent with the approach a market place participant would use. The estimation of fair value utilizing a DCF approach includes numerous uncertainties which require our significant judgment when making assumptions of expected growth rates and the selection of discount rates, as well as assumptions regarding general economic and business conditions, and the structure that would yield the highest economic value, among other factors. Key assumptions used in measuring the fair values of the Scanner reporting unit included the discount rate (based on the weighted-average cost of capital) and revenue growth. The fair value of Scanner’s trademark was determined using a risk-adjusted DCF approach under the relief-from-royalty method. The royalty rate used was based on a consideration of market rates. The fair value of Scanner’s finite-lived customer relationships was determined using a DCF approach under the multi-period excess earnings method. We determined our long-lived asset group within the Scanner reporting unit to be primarily finite-lived intangible assets, plant and equipment. Upon completion of this analysis, we recorded a total impairment charge of $26.3 million of which $19.3 million represented the impairment related to our Scanner intangible assets and $7.0 million related to plant and equipment. There was no triggering event related to the Clear Aligner asset group. Intangible assets arising either as a direct result from the Cadent acquisition or individually acquired are being amortized as follows (in thousands):
The total estimated annual future amortization expense for these acquired intangible assets as of March 31, 2014 is as follows (in thousands):

| Legal Proceedings [Abstract] | |
| Legal Proceedings | Legal Proceedings Securities Class Action Lawsuit On November 28, 2012, plaintiff City of Dearborn Heights Act 345 Police & Fire Retirement System filed a lawsuit against Align, Thomas M. Prescott (“Mr. Prescott”), Align's President and Chief Executive Officer, and Kenneth B. Arola (“Mr. Arola”), Align's former Vice President, Finance and Chief Financial Officer, in the United States District Court for the Northern District of California on behalf of a purported class of purchasers of our common stock (the "Securities Action"). On July 11, 2013, an amended complaint was filed, which named the same defendants, on behalf of a purported class of purchasers of our common stock between January 31, 2012 and October 17, 2012. The amended complaint alleged that Align, Mr. Prescott and Mr. Arola violated Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, and that Mr. Prescott and Mr. Arola violated Section 20(a) of the Securities Exchange Act of 1934. Specifically, the amended complaint alleged that during the purported class period defendants failed to take an appropriate goodwill impairment charge related to the April 29, 2011 acquisition of Cadent Holdings, Inc. in the fourth quarter of 2011, the first quarter of 2012 or the second quarter of 2012, which rendered our financial statements and projections of future earnings materially false and misleading and in violation of U.S. GAAP. The amended complaint sought monetary damages in an unspecified amount, costs and attorney's fees. On December 9, 2013, the court granted defendant's motion to dismiss with leave for plaintiff to file a second amended complaint. Plaintiff filed a second amended complaint on January 8, 2014 on behalf of the same purported class. The second amended complaint states the same claims as the first amended complaint. We filed a motion to dismiss the second amended complaint on February 7, 2014. Align intends to vigorously defend itself against these allegations. Align is currently unable to predict the outcome of this amended complaint and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. Shareholder Derivative Lawsuit On February 1, 2013, plaintiff Gary Udis filed a shareholder derivative lawsuit against several of Align's current and former officers and directors in the Superior Court of California, County of Santa Clara. The complaint alleges that our reported income and earnings were materially overstated because of a failure to timely write down goodwill related to the April 29, 2011 acquisition of Cadent Holdings, Inc., and that defendants made allegedly false statements concerning our forecasts. The complaint asserts various state law causes of action, including claims of breach of fiduciary duty, unjust enrichment, and insider trading, among others. The complaint seeks unspecified damages on behalf of Align, which is named solely as nominal defendant against whom no recovery is sought. The complaint also seeks an order directing Align to reform and improve its corporate governance and internal procedures, and seeks restitution in an unspecified amount, costs, and attorney's fees. On July 8, 2013, an Order was entered staying this derivative lawsuit until an initial ruling on our first motion to dismiss the Securities Action. On January 15, 2014, an Order was entered staying this derivative lawsuit until an initial ruling on our second motion to dismiss the Securities Action discussed above. Align intends to vigorously defend itself against these allegations. Align is currently unable to predict the outcome of this complaint and therefore cannot determine the likelihood of loss nor estimate a range of possible losses. In addition, in the course of Align's operations, Align is involved in a variety of claims, suits, investigations, and proceedings, including actions with respect to intellectual property claims, patent infringement claims, government investigations, labor and employment claims, breach of contract claims, tax, and other matters. Regardless of the outcome, these proceedings can have an adverse impact on us because of defense costs, diversion of management resources, and other factors. Although the results of complex legal proceedings are difficult to predict and Align's view of these matters may change in the future as litigation and events related thereto unfold; Align currently does not believe that these matters, individually or in the aggregate, will materially affect Align's financial position, results of operations or cash flows. |

Indemnification Provisions In the normal course of business to facilitate transactions in our services and products, we indemnify certain parties: customers, vendors, lessors and other parties with respect to certain matters, including, but not limited to, services to be provided by us and intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and our executive officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. Several of these agreements limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to make a reasonable estimate of the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Additionally, we have a limited history of prior indemnification claims and the payments we have made under such agreements have not had a material adverse effect on our results of operations, cash flows or financial position. However, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our results of operations or cash flows in a particular period. As of March 31, 2014, we did not have any material indemnification claims that were probable or reasonably possible. |

| Stock-based Compensation | Stock-based Compensation Summary of stock-based compensation expense As of March 31, 2014, we had a total reserve of 23,283,379 shares for issuance, plus up to an aggregate of 5,000,000 shares that would have been returned to our 2001 Stock Incentive Plan as a result of termination of options on or after March 28, 2005. Stock-based compensation is based on the estimated fair value of awards, net of estimated forfeitures, and recognized over the requisite service period. Estimated forfeitures are based on historical experience at the time of grant and may be revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The stock-based compensation related to all of our stock-based awards and employee stock purchases for the three months ended March 31, 2014 and 2013 is as follows (in thousands):
Options Activity for the three month period ended March 31, 2014 under the stock option plans is set forth below (in thousands, except years and per share amounts):
There were no stock options granted during the three months ended March 31, 2014 and 2013. As of March 31, 2014, the total unamortized compensation cost related to stock options, net of estimated forfeitures, is $0.6 million, which we expect to recognize over a weighted average period of 1.0 year. Restricted Stock Units (“RSU”) A summary of the RSU activity for the three months ended March 31, 2014 is as follows (in thousands, except years):
As of March 31, 2014, the total unamortized compensation cost related to RSU, net of estimated forfeitures, was $81.7 million, which we expect to recognize over a weighted average period of 2.9 years. We have granted market-performance based restricted stock units (“MSU”) to our executive officers. Each MSU represents the right to one share of Align’s common stock and will be issued through our amended 2005 Incentive Plan. The actual number of MSU which will be eligible to vest will be based on the performance of Align’s stock price relative to the performance of the NASDAQ Composite Index over the vesting period, generally two to three years, up to 150% of the MSU initially granted. The following table summarizes the MSU activity for the three months ended March 31, 2014 (in thousands, except years):
As of March 31, 2014, the total unamortized compensation costs related to the MSU, net of estimated forfeitures, was $14.1 million, which we expect to recognize over a weighted average period of 2.1 years. Employee Stock Purchase Plan ("ESPP") In May 2010, our stockholders approved the 2010 Employee Stock Purchase Plan ("2010 Purchase Plan") which will continue until terminated by either the Board of Directors or its administrator. The maximum number of shares available for purchase under the 2010 Purchase Plan is 2,400,000 shares. As of March 31, 2014, there remains 1,475,372 shares available for purchase under the 2010 Purchase Plan. The fair value of the option component of the 2010 Purchase Plan shares was estimated at the grant date using the Black-Scholes option pricing model with the following weighted average assumptions:
As of March 31, 2014, the total unamortized compensation cost related to employee purchases we expect to recognize was $2.1 million over a weighted average period of 0.7 year. |

| Accounting for Income Taxes | Accounting for Income Taxes Our provision for income taxes was $10.0 million and $2.9 million for the three months ended March 31, 2014 and 2013, respectively. This represents effective tax rates of 23.5% and (7.5)%, respectively. The increase in provision for income taxes was primarily due to higher pre-tax income, which was partially offset by a jurisdictional shift in forecasted earnings from the U.S. to lower-tax non-U.S. jurisdictions. The effective tax rate for the three months ended March 31, 2013 reflects a non-deductible goodwill impairment charge of $40.7 million. We exercise significant judgment in regards to estimates of future market growth, forecasted earnings and projected taxable income in determining the provision for income taxes, and for purposes of assessing our ability to utilize any future benefit from deferred tax assets. As of March 31, 2014, we maintained a valuation allowance of $35.4 million against deferred tax assets primarily related to foreign net operating loss carryforwards and capital loss carryforwards. These net operating and capital loss carryforwards would result in an income tax benefit if we were to conclude it is more likely than not that the related deferred tax assets will be realized. During the three months ended March 31, 2014, the change in our gross unrecognized tax benefits was not material. The total amount of gross unrecognized tax benefits was $27.9 million as of March 31, 2014, all of which would impact our effective tax rate if recognized. We have elected to recognize interest and penalties related to unrecognized tax benefits as a component of income taxes. The change in accrued interest and penalties during the three months ended March 31, 2014, was not material. We do not expect any significant changes to the amount of unrecognized tax benefit within the next twelve months. During the first quarter of 2014, we adopted ASU 2013-11, "Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force)." The adoption of this standard had the effect of reducing our accruals for uncertain tax positions by $8.4 million, with an offsetting reduction in our long term deferred tax assets, but had no effect on net income. We are subject to taxation in the U.S. and various states and foreign jurisdictions. All of our tax years will be open to examination by the U.S. federal and most state tax authorities due to our net operating loss and overall credit carryforward position. With few exceptions, we are no longer subject to examination by foreign tax authorities for years before 2006. In June 2009, the Costa Rica Ministry of Foreign Trade, an agency of the Government of Costa Rica, granted a twelve year extension of certain income tax incentives, which were previously granted in 2002. The incentive tax rates will expire in various years beginning in 2017. Under these incentives, all of the income in Costa Rica during these twelve year incentive periods is subject to reduced rate of Costa Rica income tax. In order to receive the benefit of these incentives, we must hire specified numbers of employees and maintain certain minimum levels of fixed asset investment in Costa Rica. If we do not fulfill these conditions for any reason, our incentive could lapse, and our income in Costa Rica would be subject to taxation at higher rates. The Costa Rica corporate income tax rate that would apply, absent the incentives, is 30% for 2014. As a result of these incentives, income taxes were reduced by $7.6 million and $6.0 million for the three months ended March 31, 2014 and 2013, respectively, representing a benefit to diluted net income per share of $0.09 and $0.07 in 2014 and 2013, respectively. |

| Subsequent Events | Subsequent Events On April 23, 2014, we announced that our Board of Directors had authorized a stock repurchase program pursuant to which we may purchase up to $300.0 million of our common stock over the next three years, with $100.0 million of that amount authorized to be purchased over the next twelve months. Any purchases under this stock repurchase program may be made, from time-to-time, pursuant to open market purchases (including pursuant to Rule 10b5-1 plans), privately-negotiated transactions, accelerated stock repurchases, block trades or derivative contracts or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934. As part of our $300.0 million stock repurchase program, we entered into an accelerated share repurchase agreement ("ASR") with Goldman, Sachs & Co. on April 28, 2014 to repurchase $70.0 million of our common stock. Under the terms of the ASR, we agreed to repurchase in total $70.0 million of our common stock, with an initial delivery of approximately 1.0 million shares based on current market prices. The final number of shares to be repurchased will be based on our volume-weighted average stock price during the term of the transaction, less an agreed upon discount. The ASR is expected to be completed by July 29, 2014. |

(“we”, “our”, or “Align”) in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and contain all adjustments, including normal recurring adjustments, necessary to present fairly our results of operations for the three months ended March 31, 2014 and 2013, our comprehensive income (loss) for the three months ended March 31, 2014 and 2013, our financial position as of March 31, 2014 and our cash flows for the three months ended March 31, 2014 and 2013. The Condensed Consolidated Balance Sheet as of December 31, 2013 was derived from the December 31, 2013 audited financial statements. Net revenues by geographic area for prior period amounts in Note 12 have been reclassified to conform with the current period presentation. These reclassifications had no impact on our financial position for the three months ended March 31, 2014 and 2013. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or any other future period, and we make no representations related thereto. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk” and the Consolidated Financial Statements and notes thereto included in Items 7, 7A and 8, respectively, in our Annual Report on Form 10-K for the year ended December 31, 2013. |
| Use of estimates | Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles ("GAAP") in the United States of America (“U.S.”) requires our management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, we evaluate our estimates, including those related to the fair values of financial instruments, long-lived assets and goodwill, useful lives of intangible assets and property and equipment, stock-based compensation, income taxes, and contingent liabilities, among others. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In July 2013, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-11, "Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force)." The amendments in this ASU provide guidance on the financial statements presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. An unrecognized tax benefit should 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 with certain exceptions, in which case such an unrecognized tax benefit should be presented in the financial statements as a liability. The amendments in this ASU do not require new recurring disclosures and are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this standard in the first quarter of 2014 had the effect of reducing our accruals for uncertain tax positions by $8.4 million, with an offsetting reduction in our long term deferred tax assets, but had no effect on net income. |

- Definition
Investments in debt and equity securities which are categorized neither as held-to-maturity nor trading and which are intended to be sold or mature more than one year from the balance sheet date or operating cycle, if longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors. Other than temporary declines in fair value below cost basis related to credit losses are recognized in earnings, and losses related to all other factors are recognized in other comprehensive income.
