Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents.

The aggregate expense charged against earnings to allocate the cost of intangible assets (nonphysical assets not used in production) in a systematic and rational manner to the periods expected to benefit from such assets. As a noncash expense, this element is added back to net income when calculating cash provided by or used in operations using the indirect method.

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

| Summary of Significant Accounting Policies | Note 1. 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, 2012 and 2011, our comprehensive income for the three months ended March 31, 2012 and 2011, our financial position as of March 31, 2012 and our cash flows for the three months ended March 31, 2012 and 2011. The Condensed Consolidated Balance Sheet as of December 31, 2011 was derived from the December 31, 2011 audited financial statements. The results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012 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, 2011. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our Condensed Consolidated Financial Statements and accompanying notes. Actual results could differ materially from those estimates. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted 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, intangible 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 May 2011, the FASB issued ASU 2011-04, “Fair Value Measurement (Accounting Standards Codification “ASC” 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” This accounting standard update provides certain amendments to the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for the year beginning after December 15, 2011. We adopted this standard in the first quarter of 2012. In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (ASC 220): Presentation of Comprehensive Income.” This accounting standard update eliminates the current option to report other comprehensive income and its components in the statement of stockholders’ equity. Instead, an entity will be required to present items of net income and other comprehensive income in one continuous statement or in two separate statements. The standard is effective for the year beginning after December 15, 2011. We adopted this standard in the first quarter of 2012. In September 2011, FASB issued ASU 2011-08, “Intangibles—Goodwill and Other (ASC 350): Testing Goodwill for Impairment.” This accounting standard update is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. This standard is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The adoption of this standard did not have an impact on condensed consolidated financial statements. |

Long-term
Short-term
For the three months ended March 31, 2012 and 2011, no significant gains or losses were realized on the sale of marketable securities. We had no long-term investments as of December 31, 2011. 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. We did not hold any Level 1 liabilities as of March 31, 2012. 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, foreign bonds, agency bonds, certificates of deposit, and our Israeli severance funds that are mainly invested in insurance policies. We did not hold any Level 2 liabilities as of March 31, 2012. 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, 2012. The following table summarizes our financial assets measured at fair value on a recurring basis as of March 31, 2012 (in thousands):

Work in process includes costs to produce our clear aligner and intra-oral scanner products. Finished goods primarily represent our intra-oral scanners and ancillary products that support our clear aligner products. During the first quarter of 2012, we increased our production volumes of our intra-oral scanners in preparation for the move into our new facility in Israel scheduled for the second half of 2012.
Accrued liabilities Accrued liabilities consist of the following (in thousands):
Warranty We regularly review the accrued balances and update these balances based on historical warranty trends. Actual warranty costs incurred have not materially differed from those accrued. However, future actual warranty costs could differ from the estimated amounts. Clear Aligner We warrant our Invisalign products against material defects until the Invisalign case is complete. We accrue for warranty costs in cost of net revenues upon shipment of products. The amount of accrued estimated warranty costs is primarily based on historical experience as to product failures as well as current information on replacement costs. Scanners We warrant our scanners for a period of one year from the date of training and installation. We accrue for these warranty costs which includes materials and labor based on estimated historical repair costs. Extended service packages may be purchased for additional fees.

| Business Combination | Note 4. Business Combination On April 29, 2011, we completed the acquisition of Cadent Holdings, Inc. (“Cadent”) for an aggregate cash purchase price of approximately $187.6 million. Cadent is a leading provider of 3D digital scanning solutions for orthodontics and dentistry. We believe that the combination of Align’s and Cadent’s technologies and capabilities creates greater growth opportunities for Align by bringing innovative new Invisalign treatment tools to customers and by extending the value of intra-oral scanning in dental practices. The following table summarizes the allocation of the purchase price as of April 29, 2011 (in thousands):
Goodwill of $135.3 million represents the excess of the purchase price over the fair value of the underlying net tangible and identifiable intangible assets, and represents the expected synergies of the transaction and 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 allocated approximately $77.3 million of the goodwill from the Cadent acquisition to our Scanner and CAD/CAM Services reporting unit and approximately $58.0 million to our Clear Aligner reporting unit. We allocated this goodwill to our reporting units based on the expected relative synergies generated by the acquisition. For the three months ended March 31, 2012, Cadent contributed net revenues of approximately $11.8 million and gross profit of approximately $3.4 million. Sales, marketing, development and administrative activities for our Clear Aligner and Scanner and CAD/CAM Services reporting units were integrated during the post-acquisition period, therefore the operating results below gross profit is not available. The following table presents the results of Align and Cadent for three months ended March 31, 2011, on a pro forma basis, as though the companies had been combined as of January 1, 2011.

Goodwill of $135.8 million primarily represents the excess of the purchase price of Cadent over the fair value of the underlying net tangible and identifiable intangible assets, and represents the expected relative synergies of the transaction and the knowledge and experience of the workforce in place. 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.

The total estimated annual future amortization expense for these acquired intangible assets as of March 31, 2012 is as follows (in thousands):
Impairment assessment We perform an impairment test whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Examples of such events or circumstances include significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of acquired assets or the strategy for its business, significant negative industry or economic trends, and/or a significant decline in our stock price for a sustained period. Impairments are recognized based on the difference between the fair value of the asset and its carrying value, and fair value is generally measured based on discounted cash flow analyses.

| Legal Proceedings | Note 6. Legal Proceedings Securities Litigation In August 2009, Plaintiff Charles Wozniak filed a lawsuit against us and our Chief Executive Officer and President, Thomas M. Prescott (“Mr. Prescott”), in District Court for the Northern District of California on behalf of a claimed class consisting of all persons or entities who purchased our common stock between January 30, 2007 and October 24, 2007. The complaint alleges that Align and Mr. Prescott violated Section 10(b) of the Securities Exchange Act of 1934 and that Mr. Prescott violated Section 20(a) of the Securities Exchange Act of 1934. Specifically, the complaint alleges that during the class period we failed to disclose that we had shifted the focus of our sales force to clearing backlog, causing a significant decrease in the number of new case starts. On November 13, 2009, the Court appointed Plumbers and Pipefitters National Pension Fund as lead plaintiff. The lead plaintiff filed an amended complaint on January 29, 2010. The amended complaint alleges that we and Mr. Prescott issued a number of purportedly false and misleading statements throughout the class period concerning the Patients First program, our production capacity, a purported backlog, and the focus of our sales force. On March 26, 2010, we and Mr. Prescott filed a motion to dismiss the amended complaint. The motion was heard by the Court on July 9, 2010 and on June 8, 2011, the Court granted our motion to dismiss with leave to amend. On July 22, 2011, the lead plaintiff filed a second amended complaint adding allegations that Align and Mr. Prescott issued a number of purportedly false and misleading statements throughout the class period concerning our ClinAdvisor product. On March 14, 2012, lead plaintiff dismissed with prejudice this complaint. The case was dismissed pursuant to a stipulation between the parties that prevents them from seeking or asserting any claims against one another for fees, expenses, costs, or sanctions. The stipulated dismissal with prejudice terminates the matter and follows the Court’s previous dismissal of plaintiff’s second amended complaint for failure to state a claim on February 3, 2012. As a result of this dismissal, we believe that there was no evidence to indicate that a loss had been incurred as of March 31, 2012. |

| Credit Facilities | Note 7. Credit Facilities On December 14, 2010, we renegotiated and amended our existing credit facility with Comerica Bank. Under this revolving line of credit, we have $30.0 million of available borrowings with a maturity date of December 31, 2012. The interest rate on borrowings will range from Libor plus 1.5% to 2.0% depending upon the amount of cash we maintain at Comerica Bank. This credit facility requires a quick ratio covenant and also requires us to maintain a minimum unrestricted cash balance of $10.0 million. Additionally, in the event our unrestricted cash deposited is less than $55.0 million, the unused facility fee will increase from 0.050% per quarter to 0.125% per quarter. As of March 31, 2012, we had no outstanding borrowings under this credit facility and are in compliance with the financial covenants. |

| Stock-based Compensation | Note 9. Stock-based Compensation Summary of stock-based compensation expense On May 19, 2011 the Shareholders approved an increase of 3,000,000 shares to the 2005 Incentive Plan (as amended) for a total reserve of 16,283,379 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 expense 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 expense related to all of our stock-based awards and employee stock purchases for the three months ended March 31, 2012 and 2011 are as follows (in thousands):
Options Activity for the three months period ended March 31, 2012 under the stock option plans are set forth below (in thousands, except years and per share amounts):
The fair value of stock options granted was estimated at the grant date using the Black-Scholes option pricing model with the following weighted average assumptions:
As of March 31, 2012, we expect to recognize $8.2 million of total unamortized compensation cost, net of estimated forfeitures, related to stock options over a weighted average period of 1.9 years.
Restricted Stock Units (“RSUs”) A summary of the nonvested shares for the three months ended March 31, 2012 is as follows (in thousands, except years):
As of March 31, 2012 the total unamortized compensation cost related to restricted stock units, net of estimated forfeitures, was $28.7 million, which we expect to recognize over a weighted average period of 3.0 years. On February 18, 2011, we granted market-performance based restricted stock units (“MSUs”) 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 MSUs 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 MSUs initially granted. The following table summarizes the MSU performance as of March 31, 2012:
As of March 31, 2012, we expect to recognize $5.7 million of total unamortized compensation cost, net of estimated forfeitures, related to MSU over a weighted average period of 2.3 years. Employee Stock Purchase Plan In May 2010, our shareholders approved the 2010 Employee Stock Purchase Plan (the “2010 Purchase Plan”) to replace the 2001 Purchase Plan. The terms and features of the 2010 Purchase Plan are substantially the same as the 2001 Purchase Plan and will continue until terminated by either the Board 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, 2012, there remains 2,076,302 shares available for purchase under the 2010 Purchase Plan.
The fair value of the option component of the 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, 2012, we expect to recognize $1.3 million of the total unamortized compensation cost related to employee purchases over a weighted average period of 0.6 years. |

Common Stock Repurchase Program On October 27, 2011, we announced that our Board of Directors approved a stock repurchase program pursuant to which we may repurchase up to $150.0 million of common stock. Purchases under the stock repurchase program may be made from time to time in the open market. During the first quarter of 2012, we repurchased approximately 0.1 million shares of common stock at an average price of $24.68 per share for an aggregate purchase price of approximately $2.5 million including commissions. The common stock repurchases reduced additional paid-in capital by approximately $0.9 million and increased accumulated deficit by $1.6 million. All repurchased shares were retired. |

| Accounting for Income Taxes | Note 11. Accounting for Income Taxes The financial statement recognition of the benefit for an uncertain tax position is dependent upon the benefit being more-likely-than-not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. During the first quarter of fiscal 2012, the amount of gross unrecognized tax benefits increased by $1.2 million. The total amount of unrecognized tax benefits was $16.7 million as of March 31 2012, all of which would impact our effective tax rate if recognized. 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 2007. |

Our CODM is our Chief Executive Officer. We report segment information based on the “management” approach. The management approach designates the internal reporting used by management for decision making and performance assessment as the basis for determining our reportable segments. The performance measures of our reportable segments include net revenues and gross profit.

Exit Activities In the third quarter of 2011, we announced our plan to consolidate our Carlstadt, New Jersey -based Scanner and CAD/CAM services activities with our existing manufacturing and shared services organizations in order to optimize efficiency, consolidate customer-facing functions, and reduce operating cost. The exit from our New Jersey operations includes a total reduction of 119 full time headcount in Carlstadt, New Jersey.

| Basis of presentation | 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, 2012 and 2011, our comprehensive income for the three months ended March 31, 2012 and 2011, our financial position as of March 31, 2012 and our cash flows for the three months ended March 31, 2012 and 2011. The Condensed Consolidated Balance Sheet as of December 31, 2011 was derived from the December 31, 2011 audited financial statements. The results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012 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, 2011. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our Condensed Consolidated Financial Statements and accompanying notes. Actual results could differ materially from those estimates. |
| Use of estimates | Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted 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, intangible 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 May 2011, the FASB issued ASU 2011-04, “Fair Value Measurement (Accounting Standards Codification “ASC” 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” This accounting standard update provides certain amendments to the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The standard is effective for the year beginning after December 15, 2011. We adopted this standard in the first quarter of 2012. In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (ASC 220): Presentation of Comprehensive Income.” This accounting standard update eliminates the current option to report other comprehensive income and its components in the statement of stockholders’ equity. Instead, an entity will be required to present items of net income and other comprehensive income in one continuous statement or in two separate statements. The standard is effective for the year beginning after December 15, 2011. We adopted this standard in the first quarter of 2012. In September 2011, FASB issued ASU 2011-08, “Intangibles—Goodwill and Other (ASC 350): Testing Goodwill for Impairment.” This accounting standard update is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. This standard is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The adoption of this standard did not have an impact on condensed consolidated financial statements. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
