Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.
	Ancestry.com LLC (the “Parent”) is a wholly-owned subsidiary of Ancestry.com Holdings LLC (“Holdings LLC”), which is controlled by Permira funds and co-investors. Holdings LLC is a holding company with no material operations and limited assets other than its ownership of the membership interests of Ancestry.com LLC. Holdings LLC is not individually responsible for any liabilities of Ancestry.com LLC or its subsidiaries solely for reason of being a member or participating in the management of Ancestry.com LLC.
	Ancestry.com LLC is a holding company and all operations are conducted by its wholly-owned subsidiaries. Ancestry.com LLC and its subsidiaries are collectively referred to as “Ancestry.com” or the “Company.” Ancestry.com is an online family history resource that derives revenue primarily on a subscription basis from providing customers access to a proprietary technology platform and an extensive collection of billions of historical records that have been digitized, indexed and made available online.
	Basis of Presentation
	The Condensed Consolidated Financial Statements include the accounts of Ancestry.com LLC and its consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current year presentation of the financial statements. In accordance with Accounting Standards Update (“ASU”) 2015-03, the Company’s deferred financing costs have been reclassified to be presented in the Condensed Consolidated Balance Sheets as a direct deduction from the debt liability rather than as an asset; refer to the Recent Accounting Pronouncements section below for further information. Additionally, the Income Tax Receivable line item has been reclassified to Prepaid Expenses and Other Current Assets on the Condensed Consolidated Balance Sheets.
	The following is a reconciliation of the effect of these reclassifications on the Company’s Condensed Consolidated Balance Sheets at December 31, 2014:
		At December 31, 2014
		As Reported		Adjustments			As Revised
	Assets:
	Income tax receivable	$	458	$	(458	)	$	—
	Prepaid expenses and other current assets		12,143		(500	)		11,643
	Other assets		28,514		(25,339	)		3,175
	Liabilities:
	Current portion of long-term debt		47,495		(958	)		46,537
	Long-term debt, net		824,742		(25,339	)		799,403
	Unaudited Interim Financial Statements
	The accompanying Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Comprehensive Income (Loss) and Statements of Cash Flows are unaudited. These unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP on the same basis as the audited Consolidated Financial Statements and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position, results of operations and cash flows.
	The majority of the Company’s revenues are subscription revenues, which are recognized ratably over the subscription periods; the costs to acquire subscribers are generally incurred before the Company recognizes the associated subscription revenues. Results of operations may vary between periods due to the timing of when revenues and expenses are recognized. As such, the results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.
	These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission.
	Use of Estimates
	The preparation of interim Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ materially from these estimates.
	The Company regularly evaluates its estimates to determine their appropriateness, including testing goodwill for impairment, recoverability of long-lived assets, income taxes, determination of the fair value of stock options included in stock-based compensation expense and timing for recognition of AncestryDNA revenues, among others. The Company bases its estimates on historical experience and on various assumptions that are believed to be reasonable, the results of which form the basis for the amounts recorded within the Condensed Consolidated Financial Statements.
	There have been no changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the three months ended March 31, 2015, except the adoption of ASU 2015-03 as described below in the Recent Accounting Pronouncements section.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Further, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing and uncertainty of revenue that is recognized. This guidance is effective for public companies for interim and annual periods beginning on or after December 15, 2016. For non-public companies, this guidance is effective for annual periods beginning after December 15, 2017 and interim periods within annual periods beginning after December 15, 2018. Early adoption is not permitted under U.S. GAAP. As an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), the Company has elected to delay adoption of new or revised accounting standards applicable to public companies until such pronouncements are made applicable to private companies. Once effective, entities can choose to apply the standard using either a full retrospective approach or a modified retrospective approach. The Company has not yet selected a transition method and is currently assessing the potential impact that this standard will have on its consolidated financial statements.
	In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability instead of being presented as an asset. This guidance is effective for public companies for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those years. For all other entities, this guidance is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. The new guidance is to be applied on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance and represents a change in accounting principle. The Company has early adopted this standard as of March 31, 2015. The effect of the adoption of ASU 2015-03 on the Company’s Condensed Consolidated Balance Sheets at December 31, 2014 is shown in the Basis of Presentation section above.
	In April 2015, the FASB issued ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This update provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. This guidance is effective for public companies for fiscal years and interim periods beginning after December 15, 2015. For all other entities, this guidance is effective for annual periods beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption is permitted for all entities. The new guidance is to be applied either prospectively to new cloud computing arrangements or retrospectively. The Company has early adopted this standard as of March 31, 2015 and will apply the guidance prospectively. It is not expected to have a material impact on the Company’s consolidated financial statements.

Fair Value Measurements	3. FAIR VALUE MEASUREMENTS
	Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, accounting guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels. These levels, in order of highest priority to lowest priority, are described below:
	Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.
	Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
	Level 3: Unobservable inputs are used when little or no market data is available.
	Cash equivalents are classified as Level 1 as they have readily available market prices in an active market. There were no movements between fair value measurement levels of the Company’s cash equivalents during the three months ended March 31, 2015.
	The following table summarizes the financial instruments of the Company at fair value based on the valuation approach applied to each class of security at March 31, 2015 (in thousands):
				Fair Value Measurement at Reporting Date Using
		Carrying		Quoted Prices		Significant		Significant
		Value at		in Active		Other		Unobservable

	The carrying amounts as of March 31, 2015 and December 31, 2014 for accounts receivable and accounts payable approximated their fair values due to the immediate or short-term maturities of these financial instruments. As of March 31, 2015, the fair value of debt was $893.9 million compared to $911.8 million at December 31, 2014. The fair value of debt was considered a Level 2 measurement as the value was determined using observable market inputs, such as current interest rates, credit quality and prices observable from less active markets.

Debt

Debt	3 Months Ended
	Mar. 31, 2015
Debt Disclosure [Abstract]
Debt	4. DEBT
	Credit Facility
	The Issuer has outstanding a credit facility (the “Second Amended Credit Facility”), which consists of a $457.1 million amended Term B-1 Loan (the “Amended Term B-1 Loan”) maturing in December 2018, a $165.0 million amended Term B-2 Loan (the “Amended Term B-2 Loan”) maturing in May 2018, and a $50.0 million revolving facility (the “Revolving Facility”) expiring in December 2017. As of March 31, 2015, no funds had been drawn against the Revolving Facility. Borrowings under the Revolving Facility may be used for the purpose of general working capital, capital expenditures and other general corporate purposes. The Second Amended Credit Facility allows the Issuer to borrow additional amounts up to $150.0 million plus any amount up to a pro forma total net secured leverage ratio (“Total Net Secured Leverage Ratio”), as defined in the Second Amended Credit Facility, of 4.00 to 1.00 and subject to market availability. Additional amounts can be borrowed subject to covenants in the Second Amended Credit Facility.
	Amounts borrowed under the Amended Term B-1 Loan are required to be paid in equal quarterly installments totaling 1% of the amended principal amount of the Amended Term B-1 Loan annually, with the balance payable upon maturity. Amounts borrowed under the Amended Term B-2 Loan are payable in equal quarterly installments of $8.25 million, with the balance payable upon maturity. Additionally, subject to certain conditions, a mandatory repayment is required to be made annually upon delivery of the audited financial statements. The mandatory repayment is required up to 50% of excess cash flow, based on the Company’s Total Net Secured Leverage Ratio and net cash proceeds of certain other transactions as calculated at the end of each fiscal year. Individual debt holders of the term loans may reject all or a portion of their pro rata share of any mandatory repayment. The Issuer can elect to apply a mandatory repayment as a reduction to the next eight quarterly required payments on a pro-rata basis. In March 2015, the Company made an excess cash flow mandatory repayment of $15.0 million for the year ended December 31, 2014 and elected to apply the mandatory repayment as a reduction to the next eight quarterly required payments on a pro-rata basis, as permitted under the terms of the Second Amended Credit Facility.
	The Amended Term B-1 Loan, Amended Term B-2 Loan and Revolving Facility bear interest on the outstanding unpaid principal amount at a rate equal to an applicable margin plus, at the Issuer’s option, either: (a) a base rate determined by reference to the highest of (i) the Barclays Bank PLC prime rate at such time, (ii) 0.50% in excess of the overnight federal funds rate at such time and (iii) the LIBOR rate that is in effect for a LIBOR loan with an interest period of one month plus 1.00%, provided that the base rate for the Amended Term B-1 Loan and Amended Term B-2 Loan is not less than 2.00% per annum; or (b) a LIBOR rate, provided that the LIBOR rate for the Amended Term B-1 Loan and the Amended Term B-2 Loan is not less than 1.00% per annum. The applicable margin shall mean either: (a) in the case of a base rate Amended Term B-1 Loan, 2.50%, and in the case of a base rate Amended Term B-2 Loan, 2.00%, or (b) in the case of a LIBOR Amended Term B-1 Loan, 3.50%, and in the case of a LIBOR Amended Term B-2 Loan, 3.00%. As of March 31, 2015, the interest rates on the Amended Term B-1 Loan and Amended Term B-2 Loan were equal to a LIBOR floor of 1.00% plus applicable margins of 3.50% and 3.00%, respectively. The applicable margin for the Revolving Facility is subject to step-ups and step-downs based on the Company’s Total Net Secured Leverage Ratio. The Issuer is also required to pay a commitment fee of 0.50% per annum on the unutilized commitments under the Revolving Facility, which fee decreases to 0.375% if the Total Net Secured Leverage Ratio is less than or equal to 2.75 to 1.00. The effective interest rates of both the Amended Term B-1 Loan and Amended Term B-2 Loan are approximately 5.9%.
	The Second Amended Credit Facility permits restricted payments, including dividends, out of available amounts, as defined in the Second Amended Credit Facility. Available amounts are adjusted based on the calculation of 50% of the Company’s annual retained excess cash flow. Separately, the Second Amended Credit Facility has a general basket for restricted payments of $40.0 million. As of March 31, 2015 and December 31, 2014, the Company was in compliance with all covenants of the Second Amended Credit Facility.
	The Second Amended Credit Facility also requires the Issuer to maintain an interest rate protection agreement for a period of not less than three years from the closing date such that not less than 50% of the outstanding debt of the Issuer and its restricted subsidiaries at the closing date is (i) subject to an interest rate protection agreement or (ii) fixed-rate borrowings. Accordingly, the Issuer has interest rate cap agreements with a $190.0 million total notional amount that cap the three-month LIBOR rate at 1.50% expiring March 31, 2016. This agreement, in conjunction with the fixed interest rate borrowings discussed below, met the stipulations prescribed by the Second Amended Credit Facility. The Issuer, at its discretion, has also entered into interest rate cap agreements with a $200.0 million total notional amount effective on March 31, 2016 that caps the three-month LIBOR rate at 2.00% expiring September 29, 2017. Changes in the fair value of the interest rate cap are recorded in the Condensed Consolidated Statements of Comprehensive Income (Loss) during the period of the change. The fair value as of March 31, 2015 and December 31, 2014 and the change in fair value of the interest rate caps for the three months ended March 31, 2015 and March 31, 2014 were immaterial.
	Senior Notes
	The Issuer has outstanding $300.0 million of fixed-rate 11.0% notes (the “Notes”) due in December 2020. Interest on the Notes is payable semi-annually in arrears on June 15 and December 15 of each year. The Issuer may redeem all or any portion of the Notes at any time prior to December 15, 2016 at a price equal to 100% of the aggregate principal plus an applicable premium, as defined in the indenture governing the Notes, and accrued interest. The Issuer may redeem any portion or all of the Notes on or after December 15, 2016 at redemption prices as set forth in the indenture, plus accrued and unpaid interest. In addition, the Issuer may redeem up to 35% of the aggregate principal of the Notes with an amount equal to the proceeds of certain equity offerings any time prior to December 15, 2015 at 111% plus accrued interest. Upon a change of control, the Issuer is required to make an offer to redeem all of the Notes from the holders at 101% of the principal amount thereof plus accrued interest. The Notes are guaranteed by Ancestry.com LLC and certain of its subsidiaries. The effective interest rate of the Notes is approximately 12.0%.
	The indenture governing the Notes generally permits restricted payments, as defined in the indenture, including dividends, out of a cumulative basket, which grows quarterly based on 50% of the Company’s cumulative consolidated net income since October 1, 2012. In addition, as a condition to making such payments, the Company must be in compliance with a pro-forma fixed charge coverage ratio greater than or equal to 2.0 to 1.0. Separately, the indenture has a general basket for such payments of the greater of $50.0 million or 2.5% of total assets.

	Ancestry.com Holdings LLC Senior Unsecured PIK Notes
	The Company’s parent, Holdings LLC, previously issued $400.0 million of senior unsecured payment-in-kind toggle notes (the “PIK Notes”) due October 15, 2018. In March 2015, Holdings LLC repurchased $9.8 million of the PIK Notes plus accumulated interest. To fund this repurchase, the Company issued a $10 million note receivable to its parent at 5% interest payable annually with a maturity date of December 31, 2017, which is subordinated to the PIK Notes. This note is recorded as a related party note receivable in Other Assets on the Condensed Consolidated Balance Sheets.
	Interest on the PIK Notes is payable semi-annually in arrears on April 15 and October 15 each year through maturity. The first and last interest payments on the PIK Notes are required to be payable entirely in cash. All other interest payments are required to be paid in cash, subject to cash availability and restricted payment capacity, as defined in the indenture. If interest payments are not required to be paid in cash, Holdings LLC will be entitled to pay all or a portion of the interest payment by increasing the principal amount of the PIK Notes or issuing new PIK Notes in an amount equal to the interest payment for the applicable interest period (“PIK Interest”). Cash interest on the PIK Notes will accrue at the rate of 9.625% per annum; PIK Interest will accrue at the rate of 10.375% per annum.
	The PIK Notes are senior unsecured obligations of Holdings LLC and are structurally subordinated to all the Company’s existing and future indebtedness. Additionally, the Company did not guarantee the PIK Notes, nor were any of its assets pledged as collateral for the PIK Notes. As the Company is not an obligor or a guarantor on the PIK Notes, the debt is recorded only in the financial statements of Holdings LLC and is not reflected in the Condensed Consolidated Financial Statements of Ancestry.com LLC. While not required, the Company has made and intends to make future payments to Holdings LLC related to the PIK Notes, provided that such payments are permitted under the covenants of the Second Amended Credit Facility and Notes.

Income Tax Disclosure [Abstract]
Income Taxes	6. INCOME TAXES
	For the three months ended March 31, 2015, the Company recorded an income tax benefit of $1.2 million, resulting in an effective income tax rate of (71.7)%, compared to an income tax benefit of $17.1 million, resulting in an effective income tax rate of 87.8%, for the three months ended March 31, 2014. The decrease in the effective income tax rate resulted primarily from the foreign tax rate benefit. This benefit increased the effective income tax rate during the three months ended March 31, 2014 due to the Company’s loss before income taxes, but decreased the effective income tax rate during the three months ended March 31, 2015 due to the Company’s income before income taxes.
	The Company is subject to income taxes in U.S. and foreign jurisdictions and to examination by tax authorities. Significant judgment is required in evaluating the Company’s uncertain tax positions and determining its provision for income taxes. The Company’s total gross unrecognized tax benefits at March 31, 2015 and December 31, 2014 were $17.7 million and $16.1 million, respectively. The $1.6 million increase in the gross unrecognized tax benefits at March 31, 2015 compared to December 31, 2014 resulted primarily from positions taken on the Company’s income tax returns related to intercompany transactions and foreign earnings. The gross uncertain tax positions, if recognized, would result in a reduction of tax expense.

	In January 2015, the Company entered into a $37.6 million lease agreement for a new corporate headquarters, to be constructed in Lehi, Utah. The lease has an anticipated start date of mid-2016 with a 10-year initial term.
	In February 2015, the Company entered into a 10-year content digitization and publication agreement that requires the Company to make escalating minimum annual payments totaling $20.5 million over the life of the contract. As of March 31, 2015, no payments have been made under the terms of the contract.
	Appraisal Litigation (In re: Appraisal of Ancestry.com Inc.)
	On October 21, 2012, the Company’s predecessor entered into a definitive merger agreement with Global Generations Merger Sub Inc. and its parent company, Ancestry US Holdings Inc. to acquire the Company’s predecessor entity for $32 per share of common stock (the “Merger”). Following the consummation of the Merger, three former shareholders, who, combined, owned approximately 1.4 million shares of the predecessor entity’s common stock, instituted two separate appraisal proceedings in the Court of Chancery of the State of Delaware pursuant to Del. C. § 262: Merion Capital, L.P. v. Ancestry.com, Inc. (C.A. No. 8173) and Merlin Partners LP et al. v. Ancestry.com Inc. (C.A. No. 8175). The two appraisal petitions alleged that the $32 per share price paid to the predecessor entity’s shareholders in the Merger did not represent the fair value of the Company on the date the Merger was consummated. On June 24, 2013, the Court consolidated the two pending appraisal proceedings as In re: Appraisal of Ancestry.com Inc. On February 9, 2015, the Court issued an order directing the Company to pay the fair value of $32 per share plus interest from the closing of the Merger through the date of payment. Therefore, on February 9, 2015, the Company paid a total of $51.1 million, which included releasing $45.3 million of restricted cash for the fair value of $32 per share plus $5.8 million for accrued interest.
	General
	As part of the acquisition of Archives.com from Inflection LLC, completed in August 2012, a Marketing Agreement between Inflection LLC and Z-CORP dba OneGreatFamily.com (“OGF”) was assigned to Ancestry.com Operations Inc. On or about October 10, 2014, OGF initiated a proceeding in the Fourth Judicial District Court of the State of Utah against Ancestry.com Inc. and Ancestry.com Operations Inc., which is captioned Z-CORP et al. v. Ancestry.com Inc. et al. (Civil No. 140401466). In regards to the assigned Marketing Agreement, the complaint alleges breach of contract, breach of implied covenant of good faith and fair dealing, conversion and intentional interference with prospective economic relations with alleged damages totaling over $30 million and punitive damages. On or about November 13, 2014 Ancestry.com filed a motion to dismiss the complaint in its entirety, for failing to state claims upon which relief may be granted. The Court heard oral arguments on the motion to dismiss on March 9, 2015. On April 1, 2015, the court issued a ruling granting the Company’s motion to dismiss, dismissing all claims but one with prejudice and on the merits. After OGF conceded the law had changed regarding its last claim, the final claim was dismissed without prejudice by consent of both parties. OGF has not filed an appeal, but its time to appeal has not yet expired.
	The Company has and may become party to various other legal proceedings and other claims that arise in the ordinary course of business or otherwise in the future. Such matters are subject to many uncertainties, and outcomes are not predictable with assurance. While the Company cannot assure the ultimate outcome of any legal proceeding or contingency in which it is or may become involved, the Company does not believe that any pending legal claim or proceeding arising in the ordinary course will be resolved in a manner that would have a material adverse effect on its business. Although the Company considers the likelihood of such an outcome to be remote, if one or more of these legal matters resulted in an adverse money judgment against the Company, such a judgment could have a material adverse effect on its operating results and financial conditions and may result in the Company being required to pay significant monetary damages.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Guarantor Condensed Consolidating Financial Statements	9. GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS
	The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by Ancestry.com LLC and by certain of its direct and indirect restricted subsidiaries (“Guarantor Subsidiaries”) in accordance with the indenture. All other subsidiaries that do not guarantee the Notes are “Non-Guarantors.” Each subsidiary is 100% owned directly or indirectly by the Parent, and there are no significant restrictions on the ability of the Parent or any of the Guarantor Subsidiaries to obtain funds from its subsidiaries by dividend or loan. The Parent conducts substantially all of its business through its subsidiaries. In servicing payments on the Notes and other indebtedness, the Issuer will rely on cash flows from these subsidiaries. The indenture governing the Notes provides for customary guarantee release provisions allowing the guarantee of a Guarantor Subsidiary to be automatically and unconditionally released upon certain conditions such as a sale, exchange, or transfer of substantially all of the assets or equity of the Guarantor Subsidiary, the repayment of the indebtedness that gave rise to the obligation of the Guarantor Subsidiary to guarantee the Notes, or the designation of the Guarantor Subsidiary as an Unrestricted Subsidiary, as defined in the indenture. The indenture does not provide for automatic release of the Parent’s guarantee of the Notes. See Note 4 for further information regarding the Notes.
	The Guarantor Subsidiaries are exempt from reporting under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), pursuant to Rule 12h-5 under the Exchange Act. As such, the Company is presenting the following Condensed Consolidating Balance Sheets, Statements of Comprehensive Income (Loss) and Statements of Cash Flows as set forth below of the Parent, Issuer, Guarantor Subsidiaries and the Non-Guarantor subsidiaries.
	Basis of Presentation
	The same accounting policies as described in the Condensed Consolidated Financial Statements are used by each entity in the Condensed Consolidated Financial Statements, except for the use of the equity method of accounting to reflect ownership interests in subsidiaries, which are eliminated upon consolidation. Consolidating entries and eliminations in the following Condensed Consolidated Financial Statements represent adjustments to (a) eliminate intercompany transactions between or among the Parent, the Issuer, the Guarantor Subsidiaries and the Non-Guarantors, (b) eliminate the investments in subsidiaries and (c) record consolidating entries.
	All direct and indirect domestic subsidiaries are included in Ancestry U.S. Holdings Inc.’s consolidated U.S. tax return. In the Condensed Consolidated Financial Statements, income tax benefit (expense) has been allocated based on each such domestic subsidiary’s relative pretax income to the consolidated pretax income (loss).
	Management believes that the allocations and adjustments noted above are reasonable. However, such allocations and adjustments may not be indicative of the actual amounts that would have been incurred had the Parent, Guarantor Subsidiaries and Non-Guarantors operated independently.
	Certain prior period amounts have been reclassified to conform to the current year presentation of the financial statements. Other than the adjustments related to the adoption of ASU 2015-03, as discussed in the Recent Accounting Pronouncements section in Note 1, these reclassifications did not have a significant impact on the Condensed Consolidated Financial Statements. Refer to the Basis of Presentation section in Note 1 for a reconciliation of the effect of the adoption of ASU 2015-03 on the Company’s Condensed Consolidated Balance Sheets at December 31, 2014. The reclassification of deferred financing costs described in Note 1 is applicable only to the Issuer entity.

Basis of Presentation	Basis of Presentation
	The Condensed Consolidated Financial Statements include the accounts of Ancestry.com LLC and its consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current year presentation of the financial statements. In accordance with Accounting Standards Update (“ASU”) 2015-03, the Company’s deferred financing costs have been reclassified to be presented in the Condensed Consolidated Balance Sheets as a direct deduction from the debt liability rather than as an asset; refer to the Recent Accounting Pronouncements section below for further information. Additionally, the Income Tax Receivable line item has been reclassified to Prepaid Expenses and Other Current Assets on the Condensed Consolidated Balance Sheets.
	The following is a reconciliation of the effect of these reclassifications on the Company’s Condensed Consolidated Balance Sheets at December 31, 2014:
		At December 31, 2014
		As Reported		Adjustments			As Revised
	Assets:
	Income tax receivable	$	458	$	(458	)	$	—

Unaudited Interim Financial Statements	Unaudited Interim Financial Statements
	The accompanying Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Comprehensive Income (Loss) and Statements of Cash Flows are unaudited. These unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP on the same basis as the audited Consolidated Financial Statements and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position, results of operations and cash flows.
	The majority of the Company’s revenues are subscription revenues, which are recognized ratably over the subscription periods; the costs to acquire subscribers are generally incurred before the Company recognizes the associated subscription revenues. Results of operations may vary between periods due to the timing of when revenues and expenses are recognized. As such, the results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.
	These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission.
Use of Estimates	Use of Estimates
	The preparation of interim Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ materially from these estimates.
	The Company regularly evaluates its estimates to determine their appropriateness, including testing goodwill for impairment, recoverability of long-lived assets, income taxes, determination of the fair value of stock options included in stock-based compensation expense and timing for recognition of AncestryDNA revenues, among others. The Company bases its estimates on historical experience and on various assumptions that are believed to be reasonable, the results of which form the basis for the amounts recorded within the Condensed Consolidated Financial Statements.
	There have been no changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the three months ended March 31, 2015, except the adoption of ASU 2015-03 as described below in the Recent Accounting Pronouncements section.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Further, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing and uncertainty of revenue that is recognized. This guidance is effective for public companies for interim and annual periods beginning on or after December 15, 2016. For non-public companies, this guidance is effective for annual periods beginning after December 15, 2017 and interim periods within annual periods beginning after December 15, 2018. Early adoption is not permitted under U.S. GAAP. As an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), the Company has elected to delay adoption of new or revised accounting standards applicable to public companies until such pronouncements are made applicable to private companies. Once effective, entities can choose to apply the standard using either a full retrospective approach or a modified retrospective approach. The Company has not yet selected a transition method and is currently assessing the potential impact that this standard will have on its consolidated financial statements.
	In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability instead of being presented as an asset. This guidance is effective for public companies for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those years. For all other entities, this guidance is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. The new guidance is to be applied on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance and represents a change in accounting principle. The Company has early adopted this standard as of March 31, 2015. The effect of the adoption of ASU 2015-03 on the Company’s Condensed Consolidated Balance Sheets at December 31, 2014 is shown in the Basis of Presentation section above.
	In April 2015, the FASB issued ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This update provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. This guidance is effective for public companies for fiscal years and interim periods beginning after December 15, 2015. For all other entities, this guidance is effective for annual periods beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption is permitted for all entities. The new guidance is to be applied either prospectively to new cloud computing arrangements or retrospectively. The Company has early adopted this standard as of March 31, 2015 and will apply the guidance prospectively. It is not expected to have a material impact on the Company’s consolidated financial statements.

	The same accounting policies as described in the Condensed Consolidated Financial Statements are used by each entity in the Condensed Consolidated Financial Statements, except for the use of the equity method of accounting to reflect ownership interests in subsidiaries, which are eliminated upon consolidation. Consolidating entries and eliminations in the following Condensed Consolidated Financial Statements represent adjustments to (a) eliminate intercompany transactions between or among the Parent, the Issuer, the Guarantor Subsidiaries and the Non-Guarantors, (b) eliminate the investments in subsidiaries and (c) record consolidating entries.
	All direct and indirect domestic subsidiaries are included in Ancestry U.S. Holdings Inc.’s consolidated U.S. tax return. In the Condensed Consolidated Financial Statements, income tax benefit (expense) has been allocated based on each such domestic subsidiary’s relative pretax income to the consolidated pretax income (loss).
	Management believes that the allocations and adjustments noted above are reasonable. However, such allocations and adjustments may not be indicative of the actual amounts that would have been incurred had the Parent, Guarantor Subsidiaries and Non-Guarantors operated independently.
	Certain prior period amounts have been reclassified to conform to the current year presentation of the financial statements. Other than the adjustments related to the adoption of ASU 2015-03, as discussed in the Recent Accounting Pronouncements section in Note 1, these reclassifications did not have a significant impact on the Condensed Consolidated Financial Statements. Refer to the Basis of Presentation section in Note 1 for a reconciliation of the effect of the adoption of ASU 2015-03 on the Company’s Condensed Consolidated Balance Sheets at December 31, 2014. The reclassification of deferred financing costs described in Note 1 is applicable only to the Issuer entity.
