	Description of Business and Summary of Significant Accounting Policies
	Care.com, Inc. (the “Company”, “we”, “us”, and “our”), a Delaware corporation, was incorporated on October 27, 2006. We are the world’s largest online marketplace for finding and managing family care. Our consumer matching solutions enable families to connect to caregivers and caregiving services in a reliable and easy way and our payment solutions enable families to pay caregivers electronically online or via their mobile device and to manage their household payroll and tax matters with Care.com HomePay. We also serve employers by providing access to our platform to employer-sponsored families and care-related businesses-such as day care centers, nanny agencies and home care agencies-who wish to market their services to our care-seeking families and recruit our caregiver members.
	Certain Significant Risks and Uncertainties
	We operate in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, we believe that changes in any of the following areas could have a significant negative effect on us in terms of our future financial position, results of operations or cash flows: rates of revenue growth; engagement and usage of our products; scaling and adaptation of existing technology and network infrastructure; competition in our market; management of our growth; acquisitions and investments; qualified employees and key personnel; protection of our brand and intellectual property; protection of customers’ information and privacy concerns; and security measures related to our website, among other things.
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 28, 2013, filed on March 6, 2014.
	The condensed consolidated balance sheet as of December 28, 2013, included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP on an annual reporting basis.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, and are not necessarily indicative of the results of operations to be anticipated for Fiscal 2014 or any future period.
	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries, after elimination of all intercompany balances and transactions.
	Fiscal Year-End
	For periods prior to Fiscal 2013, we operated and reported on a calendar basis fiscal year. Beginning in the third quarter of Fiscal 2013, we operate and report using a 52 or 53 week fiscal year ending on the Saturday in December closest and prior to December 31. Accordingly, our fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter.
	Use of Estimates
	The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to accounts receivable and revenue allowances, the useful lives of long-lived assets including property and equipment, intangible assets, valuation of common and preferred stock and warrants to purchase preferred stock, fair value of stock-based awards, goodwill, income taxes, contingent consideration, and contingencies. We base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from the estimates.
	Subsequent Events Consideration
	The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized subsequent events recorded in the unaudited condensed consolidated financial statements as of and for the three months ended March 29, 2014
	Recently Issued and Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, "Income Taxes (Topic740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry forward, a Similar Tax Loss, or a Tax Credit Carry forward Exists (a consensus of the FASB Emerging Issues Task Force)." This ASU states that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward, except in certain situations. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application are permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. The adoption of this amendment did not have a material impact on our condensed consolidated financial statements.
	In April 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” to reduce diversity in practice for reporting discontinued operations. Under the previous guidance, any component of an entity that was a reportable segment, an operating segment, a reporting unit, a subsidiary, or an asset group was eligible for discontinued operations presentation. The revised guidance only allows disposals of components of an entity that represent a strategic shift (e.g., disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity) and that have a major effect on a reporting entity’s operations and financial results to be reported as discontinued operations. The revised guidance also requires expanded disclosure in the financial statements for discontinued operations as well as for disposals of significant components of an entity that do not qualify for discontinued operations presentation. The updated guidance is effective for periods beginning after December 15, 2014. We currently do not have operations that are reported as discontinued operations and do not expect the adoption of this guidance to have a material effect on our financial position, results of operations, or cash flows.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for disclosure of fair value measurements. The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:
	•	Level 1 inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
	•	Level 2 inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include 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, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.), or inputs that are derived principally from or corroborated by market data by correlation or other means.
	•	Level 3 inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	Recurring Fair Value Measurements
	Assets
	Cash equivalents - Cash equivalents include money market mutual funds with original maturities of three months or less. The fair value measurement of these assets is based on quoted market prices in active markets for identical assets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy.
	Liabilities
	Contingent Acquisition Consideration - Contingent acquisition consideration includes the fair value of the contingent consideration, based on the likelihood of issuing preferred stock and paying cash related to certain revenue milestones, as part of the consideration transferred. During the year ended December 28, 2013 we reassessed the probability of achievement on the PIAP contingent acquisition cash payment based on their meeting certain revenue milestones and the probability of reaching both the 2013 and 2014 milestones which resulted in $0.6 million of incremental expense. No incremental expense was recorded in the quarter ended March 29, 2014. For contingent consideration payable in preferred stock, we used a valuation of the Company based on both an income and market approach to determine the fair value of the preferred shares as of the acquisition date and on an-ongoing basis. We recorded our estimate of the fair value of this contingent consideration based on the evaluation of the likelihood of the achievement of the contractual conditions that would result in the payment of the contingent consideration and weighted probability assumptions of these outcomes. The fair value of the liability was estimated using a discounted cash flow technique with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820, Fair Value Measurements and Disclosures . The significant inputs in the Level 3 measurement not supported by market activity included our probability assessments of expected future cash flows related to our acquisition of Breedlove during the earn-out period, appropriately discounted considering the uncertainties associated with the obligation, and calculated in accordance with the terms of the equity purchase agreement. There have been no changes in the probability of the earn-out payment through March 29, 2014. The cash portion of the contingent consideration liability has been discounted to reflect the time value of money, and therefore, as the milestone date approaches, the fair value of this liability will increase. This increase in fair value was recorded in general and administrative expenses in the accompanying consolidated statements of operations. The preferred stock portion of the contingent consideration represented a liability in accordance with ASC 480-10, Distinguishing Liabilities from Equity, and is marked to market each reporting period with changes in market value recognized in other expense, net in the accompanying consolidated statements of operations. Upon the closing of our initial public offering (“IPO”) in January 2014 the contingent consideration payable in preferred shares was automatically converted to the right to receive common shares. Contingent consideration payable in preferred shares was written up to fair value as of the closing date of the IPO and was reclassified to permanent equity as it will no longer need to be marked to market.
	Preferred Stock Warrants - Preferred stock warrants consist of warrants issued in connection with debt financings. The fair value of the warrants was determined using the Black-Scholes option-pricing model. In conjunction with the closing of the IPO, the warrant exercisable for shares of our Series A-1 Preferred Stock was automatically converted into a warrant exercisable for shares of our common stock, resulting in the reclassification of the related convertible preferred stock warrant liability to additional paid-in capital as the warrant met the criteria for equity classification upon its conversion to a warrant for the purchase of common stock. The warrant liability was re-measured to fair value prior to reclassification to additional paid-in capital. As of March 29, 2014, we had no outstanding warrant liability. Refer to Note 7 - Stockholders’ Equity (Deficit) for a discussion of the methodology used and changes in the fair value of our preferred stock warrants.
	The following table presents information about our assets and liabilities measured at fair value on a recurring basis as of March 29, 2014 and December 28, 2013 and indicates the fair value hierarchy of the valuation techniques we utilized to determine such fair value (in thousands):

	Non-Recurring Fair Value Measurements
	We remeasure the fair value of certain assets and liabilities upon the occurrence of certain events. Such assets are comprised of long-lived assets, including property and equipment, intangible assets and goodwill. No remeasurement of such assets occurred at March 29, 2014 and December 28, 2013. Other financial instruments not measured or recorded at fair value in the accompanying unaudited condensed consolidated balance sheets principally consist of accounts receivable, accounts payable, and accrued liabilities. The estimated fair values of these instruments approximate their carrying values due to their short-term nature.

	On March 3, 2014, we entered into an agreement with Consmr, Inc. (“Consmr”), the developer of a mobile application for ratings and reviews of consumer products, pursuant to which we acquired the right to hire all employees of Consmr for total consideration of $0.6 million. Approximately $0.1 million of the purchase price was held back and is payable in one year subject to the continuing employment of the employees. Such amount is being recognized as compensation expense over the required employment period. The transaction is presented as an acquisition of a business and the consideration transferred, except for the amount held back, was recorded as goodwill.
	As a result of this transaction, on March 4, 2014 all former employees of Consmr became employees of Care.com.

	Stockholders’ Equity (Deficit)
	Initial Public Offering
	On January 29, 2014, we closed our IPO in which we sold and issued 6,152,500 shares of common stock, including 802,500 shares of common stock pursuant to the exercise of the underwriters’ option to purchase additional shares, which were sold to the public at a price of $17.00 per share. We received net proceeds of approximately $95.2 million from the IPO, including the exercise of the underwriters’ over-allotment option, net of underwriters’ discounts and commissions, and after deducting offering expenses of approximately $2.1 million.
	Upon the closing of the IPO, all shares of our outstanding redeemable convertible preferred stock automatically converted into 21,490,656 shares of common stock and our outstanding warrant to purchase redeemable convertible preferred stock automatically converted into a warrant to purchase 40,697 shares of common stock at $1.72 per share.
	Common Stock
	As of March 29, 2014 and December 28, 2013, we had reserved the following shares of common stock for future issuance in connection with the following (in thousands):
		March 29, 2014			December 28, 2013
	Conversion of preferred stock	—			21,299
	Contingent consideration payable in Series E convertible preferred stock	—			383
	Contingent consideration payable in common stock	191			—
	Options issued and outstanding	3,963			3,632
	Options available for grant under stock option plans	3,526			193
	Convertible preferred stock warrants	—			41
	Common stock warrants	—			40
	Total	7,680			25,588
	Preferred Stock Warrants
	In connection with a debt financing in 2007, we issued Lighthouse Capital Partners a warrant to purchase 40,697 shares of our Series A-1 convertible preferred stock at an exercise price of $1.72 per share, expiring October 2014, which were fully exercisable upon issuance. In conjunction with the closing of our IPO in January 2014, the warrant was automatically converted into a warrant exercisable for 40,697 shares of common stock at a purchase price of $1.72 per share, which resulted in the reclassification of the related convertible preferred stock warrant liability to additional paid-in capital as the warrant met the criteria for equity classification upon conversion to a warrant to purchase common stock. In accordance with ASC 480-10 (Distinguishing Liabilities from Equity) the freestanding warrant for our preferred stock was recognized as a liability and recorded at fair value in all periods prior to its conversion into a warrant to purchase common stock. The warrant liability was re-measured to fair value prior to reclassification to additional paid-in capital. As of March 29, 2014, we had no outstanding warrant liability. The warrant was exercised during the three months ended March 29, 2014 using a net exercise method which resulted in the issuance of 38,142 shares of common stock. There were no proceeds received by us related to this transaction.
	Common Stock Warrants
	In connection with a 2010 Loan and Security Agreement, we issued a warrant to purchase a maximum of 40,000 shares of our common stock at an exercise price of $1.65 per share. The warrant was exercised during the three months ended March 29, 2014 using a net exercise method which resulted in the issuance of 37,591 shares of common stock. There were no proceeds received by us related to this transaction.
	Stock Option Plans
	On November 15, 2006, we adopted our 2006 Stock Incentive Plan (‘‘the 2006 Plan’’), which provides for the issuance of incentive and non-qualified stock options, restricted stock and other stock-based awards to employees and non-employees of the Company. We reserved 4,567,500 shares of common stock for issuance under the 2006 Plan. Options generally vest over four years, with 25% vesting upon the one-year anniversary of the date of hire, and the remaining 75% vesting quarterly over the next three years. Options granted to consultants or other non-employees generally vest over the expected service period to the Company. The options expire ten years from the date of grant. We issue new shares to satisfy stock option exercises. Only stock options have been issued under the 2006 Plan. No grants have been made under the 2006 Plan since our IPO, and no further awards will be granted under the 2006 Plan. However, the 2006 Plan will continue to govern outstanding awards granted under the 2006 Plan.
	During 2010, we granted our Chief Executive Officer a performance-based option to purchase 150,000 shares, which vests in tranches if defined corporate goals are achieved during fiscal years 2011 through 2014. We recorded a share-based compensation expense related to this award of less than $0.1 million and $0.2 million during the quarters ended March 29, 2014, and March 31, 2013, respectively.
	On January 23, 2014, we adopted the 2014 Incentive Award Plan (‘‘the 2014 Plan’’), which provides for the issuance of incentive and non-qualified stock options, restricted stock and other stock-based awards to employees, directors and non-employees of the Company and our subsidiaries. We initially reserved 4,112,048 shares of common stock for issuance under the 2014 Plan. The number of shares initially available for issuance will be increased by (i) the number of shares represented by awards outstanding under the 2006 Plan that are forfeited, lapse unexercised or are settled in cash and which following the effective date of the 2014 Plan are not issued under the 2006 Plan and (ii) an annual increase on January 1 of each calendar year beginning in 2015 and ending in 2019, equal to the lesser of (A) 4% of the shares of common stock outstanding (on an as-converted basis) on the final day of the immediately preceding calendar year and (B) an amount as determined by our board of directors. No more than 5,002,935 shares of common stock may be issued upon the exercise of incentive stock options. Options generally vest over four years, with 25% vesting upon the one-year anniversary of the date of hire, and the remaining 75% vesting quarterly over the next three years. Options granted to consultants or other non-employees generally vest over the expected service period to the Company. The options expire ten years from the date of grant. To date only stock options have been issued under the 2014 Plan.
	Stock-Based Compensation
	A summary of stock option activity for the quarter ended March 29, 2014 is as follows (in thousands for shares and intrinsic value):
			Number of Shares			Weighted-Average Remaining Contractual Term (Years)		Weighted-Average Exercise Price		Aggregate Intrinsic Value
	Outstanding as of December 28, 2013		3,439			7.98		$	4.28	$	27,148
	Granted		587					19.64

	(1) Options expected to vest reflect an estimated forfeiture rate
	Aggregate intrinsic value represents the difference between the closing stock price of our common stock and the exercise price of outstanding, in-the-money options. Our closing stock price as reported on the NYSE as of March 29, 2014 was $16.37. The total intrinsic value of options exercised was approximately $1.0 million and $0.1 million for the quarters ended March 29, 2014 and March 31, 2013, respectively. The weighted-average grant-date fair value of options granted was $9.37 and $2.68 for the quarters ended March 29, 2014 and March 31, 2013, respectively. The aggregate fair value of the options that vested during the quarters ended March 29, 2014 and March 31, 2013 was $1.3 million and $0.5 million, respectively.
	As of March 29, 2014, total unrecognized compensation cost, adjusted for estimated forfeitures, related to non-vested stock options was approximately $9.7 million, which is expected to be recognized over the next 3.1 years. As of March 29, 2014, we had 3,525,790, shares available for grant under the 2014 Plan.
	The following table presents the weighted-average assumptions used to estimate the fair value of options granted during the periods presented:

Earnings Per Share [Abstract]	'
Net Loss Per Share	'
	Net Loss Per Share
	Basic net loss per share is computed by dividing net loss attributable to common shareholders by the weighted-average number of common shares outstanding during the period. In the period ended March 31, 2013, the holders of our Series A, A-1, B, C, D, D-1and E redeemable convertible preferred stock did not have contractual obligations to share in or fund our losses. Diluted net loss per share attributable to common shareholders is computed by dividing net loss by the weighted-average number of common shares outstanding during the period and potentially dilutive common stock equivalents, except in cases where the effect of common stock equivalent would be anti-dilutive. Potential common stock equivalents consist of common stock issuable upon exercise of stock options and common stock issuable upon conversion of our redeemable convertible preferred stock and warrants to purchase our redeemable convertible preferred stock.
	The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):
		Fiscal Quarter Ended
		March 29,				March 31,
		2014				2013
	Net Loss	$	(15,544	)		$	(6,819	)

	Weighted-average shares used to compute net loss per share attributable to common stockholders:
	Basic and diluted	21,899				2,901
	The following equity shares were excluded from the calculation of diluted net loss per share attributable to common stockholders because their effect would have been anti-dilutive for the periods presented (in thousands):

	We recorded income tax expense of $0.5 million and $0.3 million for the quarters ended March 29, 2014 and March 31, 2013, respectively. The tax provision increased in the quarter ended March 29, 2014 compared to the corresponding period of the prior fiscal year, primarily due to the income tax expense related to the amortization of Breedlove goodwill for tax purposes for which there is no corresponding book deduction and certain state taxes based on operating income that are payable without regard to our tax loss carry forwards.

Segment and Geographical Information	'
	Segment and Geographical Information
	We consider operating segments to be components of the Company in which separate financial information is available that is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is the Chief Executive Officer (‘‘CEO’’). The CEO reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, we have determined that we have a single operating and reportable segment. No country outside of the United States provided greater than 10% of our total revenue. Revenue is classified by the major geographic areas in which our customers are located. The following table summarizes total revenue generated by our geographic locations (dollars in thousands):

	Certain Significant Risks and Uncertainties
	We operate in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, we believe that changes in any of the following areas could have a significant negative effect on us in terms of our future financial position, results of operations or cash flows: rates of revenue growth; engagement and usage of our products; scaling and adaptation of existing technology and network infrastructure; competition in our market; management of our growth; acquisitions and investments; qualified employees and key personnel; protection of our brand and intellectual property; protection of customers’ information and privacy concerns; and security measures related to our website, among other things.
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 28, 2013, filed on March 6, 2014.
	The condensed consolidated balance sheet as of December 28, 2013, included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP on an annual reporting basis.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, and are not necessarily indicative of the results of operations to be anticipated for Fiscal 2014 or any future period.
Principles of Consolidation	'
	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries, after elimination of all intercompany balances and transactions.
Fiscal Year-End	'
	Fiscal Year-End
	For periods prior to Fiscal 2013, we operated and reported on a calendar basis fiscal year. Beginning in the third quarter of Fiscal 2013, we operate and report using a 52 or 53 week fiscal year ending on the Saturday in December closest and prior to December 31. Accordingly, our fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter.
Use of Estimates	'
	Use of Estimates
	The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to accounts receivable and revenue allowances, the useful lives of long-lived assets including property and equipment, intangible assets, valuation of common and preferred stock and warrants to purchase preferred stock, fair value of stock-based awards, goodwill, income taxes, contingent consideration, and contingencies. We base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from the estimates.
Subsequent Events, Policy	'
	Subsequent Events Consideration
	The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized subsequent events recorded in the unaudited condensed consolidated financial statements as of and for the three months ended March 29, 2014
Recently Issued and Adopted Accounting Pronouncements	'
	Recently Issued and Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, "Income Taxes (Topic740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry forward, a Similar Tax Loss, or a Tax Credit Carry forward Exists (a consensus of the FASB Emerging Issues Task Force)." This ASU states that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward, except in certain situations. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application are permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. The adoption of this amendment did not have a material impact on our condensed consolidated financial statements.
	In April 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” to reduce diversity in practice for reporting discontinued operations. Under the previous guidance, any component of an entity that was a reportable segment, an operating segment, a reporting unit, a subsidiary, or an asset group was eligible for discontinued operations presentation. The revised guidance only allows disposals of components of an entity that represent a strategic shift (e.g., disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity) and that have a major effect on a reporting entity’s operations and financial results to be reported as discontinued operations. The revised guidance also requires expanded disclosure in the financial statements for discontinued operations as well as for disposals of significant components of an entity that do not qualify for discontinued operations presentation. The updated guidance is effective for periods beginning after December 15, 2014. We currently do not have operations that are reported as discontinued operations and do not expect the adoption of this guidance to have a material effect on our financial position, results of operations, or cash flows.
