Accounting Policies [Abstract]
Nature of Business and Basis of Presentation	1	Nature of Business and Basis of Presentation
	The Company
	SeaChange International, Inc. and its consolidated subsidiaries (collectively “SeaChange”, “we”, or the “Company”) is an industry leader in the delivery of multiscreen video. Our products and services facilitate the aggregation, licensing, management and distribution of video and television advertising content to cable television system operators, telecommunications and media companies.
	Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of SeaChange International, Inc. and its subsidiaries (“SeaChange” or the “Company”) and are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reports as well as rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany transactions and balances have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared under U.S. GAAP have been condensed or omitted pursuant to such regulations. However, we believe that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the accompanying financial statements include all adjustments necessary to present a fair presentation of the consolidated financial statements for the periods shown. These consolidated financial statements should be read in conjunction with our most recently audited financial statements and related footnotes included in our Annual Report on Form 10-K (“Form 10-K”) as filed with the SEC. The balance sheet data as of January 31, 2015 that is included in this Quarterly Report on Form 10-Q (“Form 10-Q”) was derived from our audited financial statements.
	The preparation of these financial statements in conformity with U.S. GAAP, requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Interim results are not necessarily indicative of the operating results for the full fiscal year or any future periods and actual results may differ from our estimates. During the three months ended April 30, 2015, there have been no material changes to our significant accounting policies that were described in our fiscal 2015 Form 10-K, as filed with the SEC.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	2	Fair Value Measurements
	Definition and Hierarchy
	The applicable accounting guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The guidance establishes a framework for measuring fair value and expands required disclosure about the fair value measurements of assets and liabilities. This guidance requires us to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a non-recurring basis in periods subsequent to initial measurement, in a fair value hierarchy.
	The fair value hierarchy is broken down into three levels based on the reliability of inputs and requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required, as well as the assets and liabilities that we value using those levels of inputs:
		•		Level 1 – Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
		•		Level 2 – Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not very active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•		Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The fair value of the contingent consideration obligations related to our business acquisitions are valued using Level 3 inputs.
	Valuation Techniques
	Inputs to valuation techniques are observable and unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. When developing fair value estimates for certain financial assets and liabilities, we maximize the use of observable inputs and minimize the use of unobservable inputs. When available, we use quoted market prices, market comparables and discounted cash flow projections. Financial assets include money market funds, U.S. treasury notes or bonds and U.S. government agency bonds.
	In general, and where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value. If quoted prices in active markets for identical assets or liabilities are not available to determine fair value, then we use quoted prices for similar assets and liabilities or inputs that are observable either directly or indirectly. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3.
	Fair Value Measurements of Assets and Liabilities
	The following tables set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of April 30, 2015 and January 31, 2015:

	Available-For-Sale Securities
	We determine the appropriate classification of debt investment securities at the time of purchase and reevaluate such designation as of each balance sheet date. Our investment portfolio consists of money market funds, U.S. treasury notes and bonds, and U.S. government agency notes and bonds as of April 30, 2015 and January 31, 2015. All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash equivalents. All cash equivalents are carried at cost, which approximates fair value. Our marketable securities are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of tax, reported in stockholders’ equity as a component of accumulated other comprehensive loss. The amortization of premiums and accretion of discounts to maturity are computed under the effective interest method and are included in other expenses, net, in our consolidated statements of operations and comprehensive loss. Interest on securities is recorded as earned and is also included in other expenses, net. Any realized gains or losses would be shown in the accompanying consolidated statements of operations and comprehensive loss in other expenses, net. We provide fair value measurement disclosures of available-for-sale securities in accordance with one of three levels of fair value measurement mentioned above.
	The following is a summary of cash, cash equivalents and available-for-sale securities, including the cost basis, aggregate fair value and gross unrealized gains and losses, for short- and long-term marketable securities portfolio as of April 30, 2015 and January 31, 2015:

Cash, Cash Equivalents and Marketable Securities
Cash and cash equivalents consist primarily of highly liquid investments in money market mutual funds, government sponsored enterprise obligations, treasury bills, commercial paper and other money market securities with remaining maturities at date of purchase of 90 days or less.
Restricted Cash
In December 2014, in conjunction with our acquisition of TLL, LLC (“Timeline Labs”) (see Note 3 below), we entered into an agreement to fund a $2.5 million escrow from which Timeline Labs could make withdrawals for working capital purposes in advance of the February 2, 2015 acquisition date. The unused portion as of January 31, 2015, being $1.1 million, was classified as restricted cash in our consolidated balance sheet as of January 31, 2015. On February 2, 2015 this amount was retained by the Company.
The fair value of cash, cash equivalents, restricted cash and marketable securities at April 30, 2015 and January 31, 2015 was $85.3 million and $105.4 million, respectively.
Contingent Consideration
We determined the fair value of the contingent consideration in connection with the acquisition of Timeline Labs on February 2, 2015 using a method that incorporates the Black-Scholes valuation model to establish the value of the shares of our common stock in addition to an evaluation of the probability of achievement. This fair value measurement is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Any change in the fair value of the contingent consideration subsequent to the acquisition date, such as changes in our estimates of the performance goals, will be recognized in earnings in the period the estimated fair value changes. For contingent consideration arrangements which contain an employment requirement and as a result is considered compensation expense, we will recognize a liability once the requisite service period has been completed.

Acquisition of TLL, LLC	3	Acquisition of TLL, LLC
	On February 2, 2015, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), dated as of December 22, 2014, we acquired 100% of the member interests in TLL, LLC (“Timeline Labs”), a privately-owned California-based software-as-a-service (“SaaS”) company that enables local broadcasters, national news organizations and other media companies and brands to analyze social media messages in real-time, find and broadcast social trends, and measure viewing audience engagement across television, mobile and personal computers.
	We accounted for the acquisition of Timeline Labs as a business combination and the financial results of Timeline Labs have been included in our consolidated financial statements as of the date of acquisition. Under the acquisition method of accounting, the purchase price was allocated to SeaChange’s net tangible and intangible assets based upon their fair values as of February 2, 2015.
	The preliminary allocation of the purchase price is as follows (amounts in thousands, except for share data):
	Fair value of consideration:
	Cash, net of cash acquired		$	14,186
	Closing stock consideration			3,025
	Deferred stock consideration			6,739
	Contingent consideration			514
	Total purchase price		$	24,464
	Fair value of assets acquired and liabilities assumed:
	Current assets			249
	Other long-term assets			108
	Finite-life intangible assets			6,720
	Goodwill			17,453
	Current liabilities			(66	)
	Allocated purchase price		$	24,464
	Fair Value of Consideration Transferred
	Upon completion of the acquisition, the Company made cash consideration payments to the former members of Timeline Labs in the amount of $14.2 million (“Closing Cash Consideration”), which includes $0.2 million of preliminary working capital adjustments. The Closing Cash Consideration included $1.4 million applied from an escrow that was funded by the Company in the fourth quarter of fiscal 2015. Additionally, the Company issued 344,055 shares of common stock to the former members of Timeline Labs and deposited 173,265 shares of common stock into escrow as of the acquisition date.
	The Company is also obligated to issue shares of common stock at the six month and twelve month anniversaries of the acquisition date. The aggregate acquisition date fair value of the estimated shares for both anniversary date issuances is $6.7 million and is classified in the consolidated balance sheet as a current liability.
	Contingent Consideration
	A former holder of a specified series of interest of Timeline Labs is eligible to receive additional earn-out consideration, consisting of shares of our common stock, if defined performance criteria are achieved for fiscal 2016 and 2017 without a requirement to remain as an employee of the Company. As of April 30, 2015, we have included a liability of $0.5 million in our consolidated balance sheet, which represents the fair value of the estimated shares at full achievement of the defined performance criteria. Any future changes to this liability resulting from changes in probability of achievement or changes to the fair value will be included in our consolidated statements of operations and comprehensive loss in the period which the change occurs.
	Additionally, the former holders of a specified series of interests of Timeline Labs are eligible to receive additional earn-out compensation, consisting of shares of our common stock, if defined performance criteria are achieved for fiscal 2016 and 2017, provided, that if such person was an employee of Timeline Labs as of the closing date, such person must remain an employee as of the date that all earn-out consideration would be paid, with any forfeited amounts to be reallocated to other eligible persons. As of April 30, 2015, we estimated the fair value of the aggregate liability of the employee portion of contingent consideration to be $2.7 million which we will be recognizing as the requisite service period is completed. For the three months ended April 30, 2015, we recorded a $0.5 million charge associated with this arrangement that has been included in the earn-outs and change in fair value of earn-outs in our consolidated statements of operations and comprehensive loss.
	Intangible Assets
	In determining the fair value of the intangible assets, the Company considered, among other factors, the intended use of the assets, the estimates of future performance of Timeline Lab’s products and analyses of historical financial performance. The fair values of identified intangible assets were calculated using income-based approaches based on estimates and assumptions provided by Timeline Labs’ and the Company’s management. The following table sets forth the components of the identified intangible assets associated with the Timeline Labs acquisition and their estimated useful lives:
			Useful life			Fair Value
						(Amounts in thousands)
	Tradename			7 years		$	620
	Customer contracts			7 years			4,760
	Non-compete agreements			2 years			170
	Existing technology			5 years			1,170
						$	6,720
	Acquired Goodwill
	The preliminary purchase price allocation is subject to our final determination of fair value. We recorded the $17.5 million excess of the purchase price over the fair value of the identified tangible and intangible assets as goodwill, primarily due to expected synergies between the combined companies and expanded market opportunities. The goodwill is deductible for tax purposes.
	Acquisition-related Costs
	In connection with the acquisition, we incurred approximately $0.1 million in acquisition-related costs, including legal, accounting and other professional services for the three months ended April 30, 2015. The acquisition costs were expensed as incurred and included in professional fees – other, in our consolidated statements of operations and comprehensive loss.

	Indemnification and Warranties
	We provide indemnification, to the extent permitted by law, to our officers, directors, employees and agents for liabilities arising from certain events or occurrences while the officer, director, employee or agent is, or was, serving at our request in such capacity. With respect to acquisitions, we provide indemnification to, or assume indemnification obligations for, the current and former directors, officers and employees of the acquired companies in accordance with the acquired companies’ governing documents. As a matter of practice, we have maintained directors’ and officers’ liability insurance including coverage for directors and officers of acquired companies.
	We enter into agreements in the ordinary course of business with customers, resellers, distributors, integrators and suppliers. Most of these agreements require us to defend and/or indemnify the other party against intellectual property infringement claims brought by a third party with respect to our products. From time to time, we also indemnify customers and business partners for damages, losses and liabilities they may suffer or incur relating to personal injury, personal property damage, product liability, and environmental claims relating to the use of our products and services or resulting from the acts or omissions of us, our employees, authorized agents or subcontractors. From time to time we have received requests from customers for indemnification of patent litigation claims. Management cannot reasonably estimate any potential losses, but these claims could result in material liability for us. There are no current pending legal proceedings, in the opinion of management that would have a material adverse effect on our financial position, results from operations and cash flows. There is no assurance that future legal proceedings arising from ordinary course of business or otherwise, will have a material adverse effect on our financial position, results from operations or cash flows.
	We warrant that our products, including software products, will substantially perform in accordance with our standard published specifications in effect at the time of delivery. In addition, we provide maintenance support to our customers and therefore allocate a portion of the product purchase price to the initial warranty period and recognize revenue on a straight line basis over that warranty period related to both the warranty obligation and the maintenance support agreement. When we receive revenue for extended warranties beyond the standard duration, it is deferred and recognized on a straight line basis over the contract period. Related costs are expensed as incurred.
	Revolving Line of Credit/Demand Note Payable
	We maintain a demand discretionary line of credit and a Demand Promissory Note in the aggregate amount of $20.0 million. Borrowings under the line of credit will be used to finance working capital needs and for general corporate purposes. We currently do not have any borrowings and as a result, are not subject to any financial covenants under this line.

	On September 4, 2013, our Board of Directors authorized the repurchase of up to $25.0 million of our common stock through a share repurchase program, which we increased to $40.0 million on May 31, 2014 in connection with an extension of the termination date to April 30, 2015. Under the program, we were authorized to repurchase shares through Rule 10b5-1 plans, open market purchases, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934. This share repurchase program did not obligate us to acquire any specific number of shares and could be suspended or discontinued at any time. All repurchases were expected to be funded from our current cash and investment balances. The timing and amount of shares to be repurchased was based on market conditions and other factors, including price, corporate and regulatory requirements, and alternative investment opportunities. Any shares repurchased by us under the share repurchase program reduced the number of shares outstanding. Pursuant to the share repurchase program, we executed a Rule 10b5-1 plan in June 2014 to repurchase shares. We did not repurchase any shares of our common stock during the three months ended April 30, 2015 and the repurchase authorization expired by its terms on April 30, 2015. Through April 30, 2015, we used $5.5 million of cash in connection with the repurchase 591,520 shares of our common stock (an average price of $9.31 per share) under this program.

	2011 Compensation and Incentive Plan
	In July 2011, our stockholders approved the adoption of our 2011 Compensation and Incentive Plan (the “2011 Plan”). Under the 2011 Plan, as amended in July 2013, the number of authorized shares of common stock is equal to 5,300,000 shares plus the number of shares that expired, terminated, surrendered or forfeited awards subsequent to July 20, 2011 under the Amended and Restated 2005 Equity Compensation and Incentive Plan (the “2005 Plan”). Following approval of the 2011 Plan, we terminated the 2005 Plan. The 2011 Plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock, restricted stock units (“RSUs”), deferred stock units (“DSUs”) and other equity based non-stock option awards as determined by the plan administrator by officers, employees, consultants, and directors of the Company.
	Effective February 1, 2014, SeaChange gave its non-employee members of the Board of Directors the option to receive DSUs in lieu of RSUs beginning with the annual grant for fiscal 2015. These DSUs shall fully vest one year from the grant date. The number of units subject to the DSUs is determined as of the first day of the applicable fiscal year and the shares underlying the DSUs are not vested and issued until the earlier of the director ceasing to be a member of the Board of Directors (provided such time is subsequent to the first day of the succeeding fiscal year) or immediately prior to a change in control.
	We may satisfy awards upon the exercise of stock options or vesting of RSUs with newly issued shares or treasury shares. The Board of Directors is responsible for the administration of the 2011 Plan and determining the terms of each award, award exercise price, the number of shares for which each award is granted and the rate at which each award vests. In certain instances the Board of Directors may elect to modify the terms of an award.
	Option awards may be granted to employees at an exercise price per share of not less than 100% of the fair market value per common share on the date of the grant. RSUs, DSUs and other equity-based non-stock option awards may be granted to any officer, employee, director, or consultant at a purchase price per share as determined by the Board of Directors. Option awards granted under the 2011 Plan generally vest over a period of three years and expire ten years from the date of the grant.
	We appointed a new CEO on October 20, 2014, at which time he was granted 500,000 stock options to purchase the Company’s common stock. These stock options have an exercise price equal to our closing stock price on October 20, 2014, and will vest in approximately equal increments based upon the closing price of SeaChange’s common stock. We recorded the fair value of these stock options using the Monte Carlo simulation model, since the stock option vesting is variable depending on the closing price of our traded common stock. The model simulated the daily trading price of the market-based stock options’ expected term to determine if the vesting conditions would be triggered during the term. As a result, the fair value of these stock options was estimated at $1.7 million. We have incurred stock compensation expense related to these stock options of $0.5 million since the date of grant.

Income Tax Disclosure [Abstract]
Income Taxes	12	Income Taxes
	We recorded an income tax provision from continuing operations of $0.1 million for the three months ended April 30, 2015 primarily due to the tax deductible goodwill acquired from Timeline Labs. The taxable temporary differences related to tax amortization of the acquired goodwill creates a deferred tax liability associated with an indefinite-lived intangible asset. Accordingly, the resulting deferred tax liability cannot be used as a source of income against which our deferred tax assets may be realized.
	The Company reviews all available evidence to evaluate the recovery of deferred tax assets, including the recent history of losses in all tax jurisdictions, as well as its ability to generate income in future periods. As of April 30, 2015, due to the uncertainty related to the ultimate use of certain deferred income tax assets, the Company has recorded a valuation allowance on certain of its deferred tax assets.
	Our effective tax rate in fiscal 2016 and in future periods may fluctuate on a quarterly basis as a result of changes in our jurisdictional forecasts where losses cannot be benefitted due to the existence of valuation allowances on our deferred tax assets, changes in actual results versus our estimates, or changes in tax laws, regulations, accounting principles, or interpretations thereof. We regularly review our tax positions in each significant taxing jurisdiction in the process of evaluating our unrecognized tax benefits. We make adjustments to our unrecognized tax benefits when: i) facts and circumstance regarding a tax position change, causing a change in management’s judgment regarding that tax position; ii) a tax position is effectively settled with a tax authority; and/or iii) the statute of limitations expires regarding a tax position.
	We file income tax returns in U.S. federal jurisdiction, various state jurisdictions, and various foreign jurisdictions. We are no longer subject to U.S. federal examinations before fiscal 2010. However, the taxing authorities still have the ability to review the propriety of certain tax attributes created in closed years if such tax attributes are utilized in an open tax year. Presently, we are under audit with the IRS for fiscal years 2010 through 2012.

Earnings Per Share [Abstract]
Net Loss Per Share	13	Net Loss Per Share
	Net loss per share is presented in accordance with authoritative guidance which requires the presentation of “basic” and “diluted” earnings per share. Basic net loss per share is computed by dividing earnings available to common shareholders by the weighted-average shares of common stock outstanding during the period. For the purposes of calculating diluted net loss per share, the denominator includes both the weighted average number of shares of common stock outstanding during the period and the weighted average number of shares of potential dilutive shares of common stock, such as stock options, RSUs and DSUs, calculated using the treasury stock method. Basic and diluted net loss per share was the same for all the periods presented as the impact of potential dilutive shares outstanding was anti-dilutive due to the Company’s net loss position.
	The following table sets forth our computation of basic and diluted net loss per common share (amounts in thousands, except per share amounts):

Recent Accounting Standard Updates	14	Recent Accounting Standard Updates
	We consider the applicability and impact of all Accounting Standards Updates. Updates not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.
	Intangibles-Goodwill and Other-Internal-Use Software
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates No. (“ASU”) 2015-05, “Intangibles-Goodwill and Other-Internal-Use Software – Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This guidance is intended to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement, primarily to determine whether the arrangement includes a sale or license of software. ASU 2015-05 is effective for us beginning in fiscal 2017. Early adoption is permitted. Upon adoption, an entity has the option to apply the provisions of ASU 2015-05 either prospectively to all arrangements entered into or materially modified, or retrospectively. We are currently evaluating the impact of the adoption of ASU 2015-05 on our consolidated financial statements.
	Amendments to the Consolidation Analysis
	In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis.” ASU 2015-02 is intended to improve guidance for limited partnerships, limited liability corporations and securitization structures. The guidance places more emphasis on risk of loss when determining a controlling financial interest, reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a VIE and changes consolidation conclusions for public and private companies that typically make use of limited partnerships or VIEs. This guidance is effective for us beginning in fiscal 2017. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2015-02 on our consolidated financial statements.
	Accounting For Share-Based Payments- Performance Target Could Be Achieved after the Requisite Service Period
	In June 2014, the FASB issued ASU 2014-12, “Compensation - Stock Compensation (Topic 718) – Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” ASU 2014-12 requires that a performance target which affects vesting and that could be achieved after the requisite service period be treated as a performance condition by applying existing guidance in Topic 718 as it relates to awards with performance conditions. The amendment also specifies the period over which compensation costs should be recognized. The amendment is effective for annual reporting periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2014-12 on our consolidated financial statements.
	Revenue from Contracts with Customers
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and the International Financial Reporting Standards. This guidance supersedes previously issued guidance on revenue recognition and gives a five step process an entity should follow so that the entity recognizes revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for our fiscal 2018 reporting period and must be applied either retrospectively during each prior reporting period presented or retrospectively with the cumulative effect of initially applying this guidance recognized at the date of the initial application. Early adoption is not permitted. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of SeaChange International, Inc. and its subsidiaries (“SeaChange” or the “Company”) and are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reports as well as rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany transactions and balances have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared under U.S. GAAP have been condensed or omitted pursuant to such regulations. However, we believe that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the accompanying financial statements include all adjustments necessary to present a fair presentation of the consolidated financial statements for the periods shown. These consolidated financial statements should be read in conjunction with our most recently audited financial statements and related footnotes included in our Annual Report on Form 10-K (“Form 10-K”) as filed with the SEC. The balance sheet data as of January 31, 2015 that is included in this Quarterly Report on Form 10-Q (“Form 10-Q”) was derived from our audited financial statements.
	The preparation of these financial statements in conformity with U.S. GAAP, requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Interim results are not necessarily indicative of the operating results for the full fiscal year or any future periods and actual results may differ from our estimates. During the three months ended April 30, 2015, there have been no material changes to our significant accounting policies that were described in our fiscal 2015 Form 10-K, as filed with the SEC.
Fair Value Measurements	Fair Value Measurements
	Definition and Hierarchy
	The applicable accounting guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The guidance establishes a framework for measuring fair value and expands required disclosure about the fair value measurements of assets and liabilities. This guidance requires us to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a non-recurring basis in periods subsequent to initial measurement, in a fair value hierarchy.
	The fair value hierarchy is broken down into three levels based on the reliability of inputs and requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required, as well as the assets and liabilities that we value using those levels of inputs:
		•	Level 1 – Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.
		•	Level 2 – Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not very active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The fair value of the contingent consideration obligations related to our business acquisitions are valued using Level 3 inputs.
	Valuation Techniques
	Inputs to valuation techniques are observable and unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. When developing fair value estimates for certain financial assets and liabilities, we maximize the use of observable inputs and minimize the use of unobservable inputs. When available, we use quoted market prices, market comparables and discounted cash flow projections. Financial assets include money market funds, U.S. treasury notes or bonds and U.S. government agency bonds.
	In general, and where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value. If quoted prices in active markets for identical assets or liabilities are not available to determine fair value, then we use quoted prices for similar assets and liabilities or inputs that are observable either directly or indirectly. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3.
