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 holding company and all operations are conducted by its wholly-owned subsidiaries. Ancestry.com LLC and its subsidiaries are collectively referred to as the “Successor”, “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. On October 21, 2012, the Company’s predecessor, Ancestry.com Inc. (the “Predecessor” or “Issuer”), entered into a definitive merger agreement (the “Merger Agreement”) with Global Generations Merger Sub Inc. (the “Merger Sub”) and its parent company, Ancestry US Holdings Inc. (“Holdings”), to acquire the Predecessor for $32.00 per share of common stock (the “Merger”). Holdings is a wholly-owned subsidiary of the Ancestry.com LLC, which is controlled by Permira funds and co-investors (the “Sponsors”). On December 28, 2012, pursuant to the Merger Agreement, the Parent through its wholly-owned subsidiaries completed its acquisition of the Predecessor for approximately $1.5 billion. The Merger and all activity related to the Merger is referred to collectively as the “Transaction”. Other than the change of control, the Company’s primary business activities remain unchanged after the Transaction. See Note 2 for further discussion.
	Basis of Presentation
	The 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”). Due to the Transaction, the interim condensed consolidated financial statements are presented for Successor and Predecessor periods, which relate to periods succeeding and preceding the Transaction, respectively. As a result of the Transaction, the condensed consolidated financial statements prior to and subsequent to the Transaction are not necessarily comparable. 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. These reclassifications did not have a significant impact on the condensed consolidated financial statements.
	Unaudited Interim Financial Statements
	The accompanying condensed consolidated balance sheets and the condensed consolidated statements of comprehensive income (loss) and 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, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly 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 and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	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, 2012 included in the Company’s registration statement on Form S-4 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, the estimated useful lives of the Company’s intangible assets, including content databases, determination of fair value of stock options included in stock-based compensation expense and allowances for sales returns and uncollectible accounts receivable. 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 registration statement on Form S-4 for the three and nine months ended September 30, 2013.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11, Presentation of Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, an amendment to FASB Accounting Standards Codification (“ASC”) Topic 740, Income Taxes. This update clarifies 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 carryforward, a similar tax loss or a tax credit carryforward. In situations where a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be netted with the deferred tax asset. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013 for public companies and after December 15, 2014 for non-public companies. Early adoption is permitted. As an “emerging growth company” under 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. The Company plans to adopt this standard prospectively for fiscal years beginning after December 15, 2014. The adoption of this standard is not expected to have a material effect on the Company’s financial position or results of operations.

	10. BUSINESS ACQUISITION
	In September 2013, the Company completed the acquisition of Find A Grave, Inc., an online cemetery database. The assets acquired and liabilities assumed from this transaction were recorded based on their estimated fair values at the date of acquisition. The final purchase price allocation for the acquisition is subject to change based on finalization of the valuation of intangible assets and the resolution of any potential indemnification obligations. This acquisition was not material to the Company’s financial position or results of operations.

	2. TRANSACTION
	As discussed in Note 1 above, on December 28, 2012, pursuant to the Merger Agreement, Ancestry.com LLC through its wholly-owned subsidiaries completed the acquisition of the Predecessor for approximately $1.5 billion.
	The Transaction was accounted for under FASB ASC Topic 805, Business Combinations. The purchase price was allocated to the underlying tangible and intangible assets acquired and liabilities assumed based on their respective fair values, with the remainder allocated to goodwill. The purchase price allocation is subject to change based on the finalization of the fair value of the assets and liabilities acquired. ASC 805 requires that as the fair value of assets and liabilities are finalized, resulting increases or decreases to the preliminary values are offset by a change in goodwill. Modifications to the purchase price allocation reflected in the “Adjustments” column below were to adjust the deferred tax liability. The purchase price was allocated as follows (in thousands):
		December 31,			Adjustments			September 30,

	Total net assets acquired	$	1,502,408		$	—		$	1,502,408
	In conjunction with the Transaction, shares of the Predecessor’s common stock for which appraisal rights were duly exercised under Delaware law were canceled and converted into the right to receive the fair value of such share in accordance with Delaware law. Following the Merger, the holders of such dissenting shares ceased to have any rights with respect to such shares, except for their rights to seek an appraisal under Delaware law. Ancestry.com LLC remained liable for payment for the dissenting shares. As of September 30, 2013 and December 31, 2012, the Company had restricted cash of $45.3 million and $68.0 million, respectively, for this purpose. The related liability is recorded in Acquisition-related liabilities on the condensed consolidated balance sheets as of September 30, 2013 and December 31, 2012. If the fair value of these shares is determined to be greater than the $32.00 per share merger price, the Company would incur additional expense. The fair value of the liability was considered a Level 2 measurement as the value was determined based on observable prices from inputs not quoted on active markets. See Note 9 for further information regarding the litigation.

FAIR VALUE MEASUREMENTS	'
	4. 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 due to 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 nine months ended September 30, 2013.
	The following table summarizes the financial instruments of the Company at fair value based on the valuation approach applied at September 30, 2013 (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 September 30, 2013 and December 31, 2012 for accounts receivable and accounts payable approximated their fair values due to the immediate or short-term maturities of these financial instruments. As of September 30, 2013, the fair value of debt was $961.8 million. As of December 31, 2012, the carrying value of debt approximated its fair value based on interest rates available to the Company for debt with similar terms. 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 as well as prices observable from less active markets.

DEBT

Debt Disclosure [Abstract]	'
DEBT	'
	5. DEBT
	Credit Facility
	In December 2012, in connection with the Transaction, the Issuer entered into a $720.0 million credit facility (the “Credit Facility”), consisting of a $670.0 million term loan (“Term Loan”) maturing in December 2018 and a $50.0 million revolving credit facility (“Revolving Facility”) expiring in December 2017, of which $50.0 million was available to borrow at September 30, 2013 and December 31, 2012.
	On May 15, 2013, the Company completed a repricing of the Credit Facility and entered into Amendment No. 1 to the Credit Facility agreement (the “Amended Credit Facility”). The Company used $30.0 million of cash-on-hand to decrease the aggregate principal amount of the Term Loan to $638.3 million prior to the repricing. As part of Amendment No. 1, the Company repriced the Term Loan such that the holders thereof will hold $488.3 million of Term B Loans (the “Term Loan B”), which will have the same maturity as the original Term Loan of December 2018, and a new $150.0 million tranche of Term A Loans (the “Term Loan A”), which will mature in May 2018.
	In accordance with ASC 470-50 Debt – Modifications and Extinguishments, the Company performed an analysis resulting in the effects of the repricing being accounted for as either a debt modification or an extinguishment on a creditor-by-creditor basis. For the portion of the Term Loan that was considered to be modified, there was no acceleration of amortization of the associated original issue discount and deferred financing costs. For the portion of the Term Loan that was considered extinguished, the Company accelerated the amortization of the associated original issue discount and deferred financing costs of $4.1 million and $3.5 million, respectively. In conjunction with the repricing, the Company paid a fee equal to 1% of the outstanding principal amount of the Term Loan, or $6.4 million, to existing lenders and customary fees and expenses of $1.4 million. Repricing fees totaled $7.8 million, of which the Company recorded $1.6 million as interest expense and $6.2 million as deferred financing costs. In total, the Company recognized $9.2 million of additional interest expense during the nine months ended September 30, 2013 due to the effects of the repricing. As of September 30, 2013, the original issue discounts associated with Term Loan A and Term Loan B of $0.7 million and $19.1 million were classified as current portion of long-term debt and long-term debt, net, respectively and deferred financing costs of $1.0 million and $22.0 million were classified as prepaid expense and other current assets and as other assets, respectively, on the condensed consolidated balance sheets. The original issue discount and deferred financing costs will be amortized over the loan terms using the effective interest method.
	Amounts borrowed under the Term Loan A are required to be paid in equal quarterly installments of $7.5 million through maturity. Amounts borrowed under the Term Loan B are required to be paid in equal quarterly installments totaling 1% of the amended principal amount of the Term Loan B annually, with the balance payable upon maturity. Additionally, subject to certain conditions, mandatory prepayments are required to be made annually beginning in 2015 upon delivery of the 2014 audited financial statements. Mandatory prepayments are required up to 50% of excess cash flow, based on the net secured leverage ratio and net cash proceeds of certain other transactions. The Amended Credit Facility allows the Issuer to borrow up to $150.0 million plus additional amounts provided the pro forma total net secured leverage ratio does not exceed 4.0 to 1.0. As of September 30, 2013 and December 31, 2012, the Company was in compliance with all covenants.
	The credit agreement governing the Amended Credit Facility generally permits dividends out of “available amounts” (defined as retained excess cash flow not otherwise required to be applied to repay borrowings under the Amended Credit Facility). The available amount formulation includes a starter amount of $25.0 million and will include available amounts beginning with respect to fiscal year ended December 31, 2014. However, available amounts are only adjusted annually upon the delivery of the Company’s audited financial statements. Available Amounts are adjusted based on the calculation of 50% of the Company’s retained excess cash flow for such year under the terms of the credit agreement. In addition, as a condition to making such payments to the Issuer, the Company must be in compliance with the Amended Credit Facility. Separately, the credit agreement governing the Amended Credit Facility has a general basket for such payments of $25.0 million.
	As of September 30, 2013, the interest rates on the Term Loan A and Term Loan B were equal to a LIBOR floor of 1.00% and 1.25% plus applicable margins of 3.25% and 4.00%, respectively. As of December 31, 2012, the interest rate on the original Term Loan was equal to a LIBOR floor of 1.25% plus an applicable margin of 5.75%. The Issuer is also required to pay a commitment fee of 0.50% per annum on the unutilized commitments under the Revolving Facility. The effective interest rates of the Term Loan A and Term Loan B are approximately 6.4% and 7.1%, respectively. The effective interest rate of the original Term Loan was approximately 8.6%.
	As of September 30, 2013 and December 31, 2012, 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 capital needs.
	The 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 Company has interest rate cap agreements with a $190.0 million total notional amount, which cap the three-month LIBOR rate at 1.50% expiring March 31, 2016. These agreements, in conjunction with the fixed interest rate borrowings discussed below, met the stipulations prescribed by the Amended Credit Facility agreement. 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 and the change in fair value of the interest rate caps as of and for the three and nine months ended September 30, 2013 were immaterial.
	Senior Notes
	In December 2012, in connection with the Transaction, the Issuer issued $300.0 million of fixed rate 11.0% notes (“Original Notes”) due in December 2020. In August 2013, the Issuer completed its offer to exchange the Original Notes for $300.0 million in new fixed rate 11.0% notes (“Notes”) due 2020. The Notes are substantially identical to the Original Notes except that they have been registered under the Securities Act of 1933, as amended, are not subject to transfer restrictions, are not entitled to registration rights and do not provide for the payment of additional interest under circumstances relating to the timing of the exchange offer.
	Interest on the Notes is payable semi-annually in arrears on June 15 and December 15, commencing on June 15, 2013. 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 the applicable premium, as defined in the indenture, and accrued interest. The Issuer may redeem any portion or all of the Notes 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 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 the payment of dividends out of a cumulative basket based an aggregate amount not to exceed $50.0 million, which grows quarterly based on 50% of Company’s cumulative Consolidated Net Income, as defined in the indenture governing the Notes, since October 1, 2012. In addition, as a condition to making such payments to the Issuer, the Company must be in compliance with a fixed charge coverage ratio.

	Ancestry.com Holdings LLC Senior Unsecured PIK Notes
	On September 17, 2013, the Company’s parent, Ancestry.com Holdings LLC (“Holdings LLC”), closed a private offering of $300.0 million aggregate principal amount of senior unsecured payment-in-kind toggle notes due October 15, 2018 (the “PIK Notes”). 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. The PIK Notes were issued at 99% of par, resulting in an original issue discount of $3.0 million. Interest on the PIK Notes is payable semi-annually in arrears on April 15 and October 15 each year through maturity, commencing on April 15, 2014. The first and last interest payments on the PIK Notes will be entirely payable in cash. All other interest payments are required to be paid in cash. Subject to cash availability and restricted payment capacity, Holdings LLC will be entitled to pay all or a portion of the interest payment by increasing the principal amount of the notes or issuing new 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. Holdings LLC subsequently distributed the proceeds of the debt offering, net of the original issue discount and related fees and expenses, to its indirect parent entity to fund a return-of-capital distribution to its indirect parent entity’s shareholders and stock-based award holders.
	The PIK Notes are senior unsecured obligations of Holdings LLC and are structurally subordinated to all existing and future indebtedness of the Company. Additionally, the Company did not guarantee the PIK Notes, nor were any of the Company’s 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 consolidated financial statements of Ancestry.com LLC. While not required, the Company intends to make dividends to Holdings LLC in order to fund cash interest payments of the PIK Notes, provided that such dividends are permitted under the covenants of the Amended Credit Facility and Notes. If interest on the PIK Notes is paid in cash, annual interest payments will total approximately $28.9 million.

STOCK-BASED AWARDS	'
	7. STOCK-BASED AWARDS
	In connection with the Transaction, the Company’s indirect parent adopted the Predecessor’s 2009 Stock Incentive Plan, the Generations Holding, Inc. Stock Purchase and Option Plan and the 2004 Stock Option Plan (the “Predecessor Plans”). The Company’s indirect parent does not anticipate issuing additional awards under these plans. All awards granted and outstanding pursuant to these plans have a term not greater than ten years from the original date of grant.
	During the nine months ended September 30, 2013, the Company’s indirect parent adopted the 2013 Equity Incentive Plan, which provides for employees, directors and consultants of the Company to be granted options and restricted stock units (“RSUs”), which represent the option to purchase or rights to own “Investor Interests” in an indirect parent entity of the Company, respectively.
	In September 2013, the Company’s indirect parent entity paid a return-of-capital distribution to its shareholders and stock-based award holders. Under the terms of the Predecessor Plans and the 2013 Equity Incentive Plan, an equitable adjustment was required to be made to all stock-based awards outstanding upon a return-of-capital distribution such that no dilution or enlargement of benefits occurred. The stock-based awards outstanding as of the date of the distribution were modified as follows:
		•		Options outstanding were modified such that the exercise price of each option was reduced by the same percentage as the return-of-capital distribution percentage. Holders of in-the-money options also received a cash distribution.
		•		The holders of RSUs outstanding either received an immediate cash distribution or will receive a cash distribution upon the vesting of the awards dependent upon the terms of the individual award and the equity plan under which the award was originally granted.
	In accordance with ASC 718 – Stock Compensation, the changes to the awards were accounted for as a modification. As such, the fair value of each award immediately before and after the modification was compared and no incremental stock-based compensation cost was recognized.
	The disclosures below have been updated to retroactively reflect the effects of the return-of-capital distribution for the weighted-average exercise price of the options and weighted-average grant date fair value of the RSUs granted under the 2013 Equity Incentive Plan.
	Stock Options
	Stock options granted are in an indirect parent entity or a subsidiary of the Company.
	Each option in the indirect parent entity entitles the grantee to an investor interest in that entity upon exercise. The activity for stock options in an indirect parent entity of the Company for the nine months ended September 30, 2013 was as follows:
			Number of			Weighted
			Units			Average
			(In thousands)			Exercise
						Price
	Outstanding at December 31, 2012			315		$	13.06
	Granted			296			88.96

	Exercisable at September 30, 2013			344			19.35
	Vested and expected to vest at September 30, 2013			596			48.81
	The Company estimates the fair value of each stock option on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires several estimates including an estimate of the fair value of the underlying investor interest. The fair value of the underlying investor interest was based on the fair value on the grant date. The expected term of the options was based on the remaining contractual term of the options and the expected exercise behavior of employees. The Company calculated its expected volatility based on the volatilities of a peer group of publicly traded companies. The risk-free interest rate of the option is based on the U.S. Treasury rate for the expected term of the option. The following weighted average assumptions were used in the calculations for the nine months ended September 30, 2013 and 2012:
			Successor			Predecessor
			Nine months ended
			September 30,
			2013			2012
	Expected volatility			44.6	%		47.5	%
	Expected term (in years)			5			4.2

	Weighted average fair value of the underlying investor interest/common stock		$	88.96		$	23.33
	Expected dividends			—			—
	Each option in the Company’s subsidiary entitled the grantee to one common share in the subsidiary entity. Per the terms of the Merger Agreement, outstanding options in the subsidiary of the Company were required to be exercised within 30 days of the closing date of the Transaction. Immediately following the first anniversary of the option exercise date, the shares must then be contributed to the indirect parent entity in exchange for an equivalent number of investor interests. The activity for stock options in the subsidiary of the Company for the nine months ended September 30, 2013 was as follows:
			Number of			Weighted
			Units			Average
			(In thousands)			Exercise

	Restricted Stock Units
	Each RSU entitles the grantee to an investor interest in an indirect parent entity of the Company, or, at the discretion of the indirect parent entity, cash equal to the fair market value of the award at the settlement date. RSUs granted during the nine months ended September 30, 2013 generally vest over one year.

	8. INCOME TAXES
	For the three and nine months ended September 30, 2013, the Company recorded an income tax benefit of $13.0 million and $53.4 million, respectively, compared to income tax expense of $11.1 million and $27.0 million, respectively, for the three and nine months ended September 30, 2012. For the three months ended September 30, 2013, the Company’s effective income tax rate was 48.9%, an increase of 18.1 percentage points compared to the three months ended September 30, 2012. The increase in the effective income tax rate resulted primarily from the foreign tax rate benefit, which reduced the effective income tax rate during the three months ended September 30, 2012, but increased the effective income tax rate during the three months ended September 30, 2013 due to the Company’s loss before income taxes.
	For the nine months ended September 30, 2013, the Company’s effective income tax rate was 48.6%, an increase of 17.0 percentage points compared to the nine months ended September 30, 2012. The increase in the effective income tax rate resulted primarily from the foreign tax rate benefit, which reduced the effective income tax rate during the nine months ended September 30, 2012, but increased the effective income tax rate during the nine months ended September 30, 2013 due to the Company’s loss before income taxes. Additionally, the Company recognized 2012 federal research and development tax credits during the nine months ended September 30, 2013. This credit, which increased the effective income tax rate, was recorded during the nine months ended September 30, 2013, as a result of the American Taxpayer Relief Act of 2012, enacted on January 2, 2013.
	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 September 30, 2013 and December 31, 2012 were $5.6 million and $4.5 million, respectively. The $1.1 million increase in the gross unrecognized tax benefits at September 30, 2013 compared to December 31, 2012 resulted primarily from positions taken on the Company’s income tax returns related to various tax credits. The gross uncertain tax positions, if recognized, would result in a reduction of tax expense.

	Litigation Challenging the Transaction (In re: Ancestry.com Inc. Shareholder Litigation)
	Following the announcement on October 22, 2012 of the execution of the Merger Agreement, litigation challenging the Transaction ensued. The Court of Chancery of the State of Delaware dismissed the claims in the litigation with prejudice on September 27, 2013. As of October 30, 2013, plaintiffs had not appealed the Court of Chancery’s decision. The discussion below further details the history of the litigation.
	The following complaints were filed in the Court of Chancery challenging the proposed acquisition of the Company: Heck v. Sullivan, et al. (C.A. No. 7893), Smilow v. Ancestry.com Inc., et al. (C.A. No. 7987), Boca Raton Police & Firefighters’ Retirement System v. Billings, et al. (C.A. No. 7989), Pontiac General Employees Retirement System v. Billings (C.A. No. 7988), Dale G. & Donella M. Jacobs Trust v. Ancestry.com Inc., et al. (C.A. No. 8004), Palumbo et ano. v. Spectrum Equity Investors LP, et al. (C.A. No. 8016), Windemuth v. Ancestry.com Inc., et al.(C.A. No. 8013), Althaver v. Ancestry.com Inc., et al. (C.A. No. 8023), and Steamfitters Local 449 Pension Fund v. Ancestry.com Inc., et al. (C.A. No. 8034). Each of the actions is a putative class action filed on behalf of the public stockholders of the Predecessor and names as defendants the Company, its directors, Holdings and Merger Sub. All but the Heck action also name Permira as a defendant. The Boca Raton Police & Firefighters’ Retirement System, Pontiac General Employees Retirement System, Dale G. & Donella M. Jacobs Trust, Palumbo, Windemuth, Althaver and Steamfitters Local 449 Pension Fund complaints also name Howard Hochhauser and Spectrum as defendants. All of these actions have been consolidated as In re: Ancestry.com Inc. Shareholder Litigation (Consolidated C.A. No. 7988). The complaints generally allege that the individual defendants breached their fiduciary duties in connection with their consideration and approval of the Merger and that the entity defendants aided and abetted those breaches. The complaints seek, among other relief, declaratory and injunctive relief enjoining the Merger. On December 17, 2012, the Court heard argument in In re: Ancestry.com Inc. Shareholder Litigation on plaintiffs’ motion to preliminarily enjoin the proposed merger between the Predecessor and Merger Sub and the upcoming special meeting of the Predecessor’s stockholders that was to be held to vote on the Merger. At the conclusion of the hearing, the Court required that the Predecessor disclose certain information before the special meeting of the Predecessor’s stockholders could proceed and otherwise denied the substantive aspects of the motion for a preliminary injunction. The information required to be disclosed by the Court was disclosed on December 19, 2012 and the Merger was consummated on December 28, 2012. The litigation has continued following the consummation of the transaction.
	On March 8, 2013, the plaintiffs filed an amended complaint. The amended complaint, like the original operative complaint, names Ancestry.com, the members of Ancestry.com’s then-board of directors, Ancestry.com’s Chief Executive Officer and Chief Financial Officer, Permira, Holdings, Merger Sub and entities associated with Spectrum Equity as defendants. The amended complaint generally alleges that Ancestry’s then-board of directors, its Chief Executive Officer and Chief Financial Officer and the entities associated with Spectrum breached their fiduciary duties in connection with their consideration and approval of the merger transaction and that Ancestry filed a materially false and misleading proxy in connection with the Merger. In addition, the amended complaint alleges that Permira and its affiliated entities aided and abetted the above-described alleged breaches of fiduciary duty. The amended complaint seeks compensatory damages and an award of the costs and disbursements incurred in the litigation. On April 26, 2013, all of the defendants named in the amended complaint filed motions seeking to have the amended complaint dismissed. On September 27, 2013, arguments on the motions to dismiss were heard and the Court granted defendants’ motion to dismiss with prejudice.
	Appraisal Litigation (In re: Appraisal of Ancestry.com Inc.)
	Following the consummation of the Transaction, three former shareholders, who, combined, owned approximately 1.415 million shares of the Predecessor’s common stock have 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 allege that the $32 per share price paid to the Predecessor’s shareholders in the Transaction did not represent the fair value of the Company on the date the Transaction was consummated. On June 24, 2013, the Court consolidated the two pending appraisal proceedings as In re: Appraisal of Ancestry.com Inc.
	In view of the inherent difficulty of predicting the outcome of such litigation, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, the Company generally cannot predict or reasonably estimate what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what any loss or range of loss related to each pending matter may be. With respect to its outstanding legal matters, the Company believes that it has substantial defenses to the claims asserted by the claimants in the litigations to which it is a party. Based on its current knowledge, the Company does not believe that a loss, if any, arising from the pending matters should have a material adverse effect on its consolidated financial position.
	The Company is party to various 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 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.

	11. GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS
	In August 2013, the Issuer completed its offer to exchange the Original Notes for $300.0 million in new fixed rate 11.0% notes (“Notes”) due 2020. 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 to be made on the Notes and other indebtedness, the Issuer will rely on cash flows from these subsidiaries. See Note 5 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 consolidating 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 consolidating 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.com Inc.’s consolidated U.S. tax return. In the condensed consolidating 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).
	Certain transfers of cash between subsidiaries and their parent companies and intercompany dividends are reflected as cash flows from financing activities in the accompanying condensed consolidating statements of cash flows. All other intercompany activity is reflected in cash flows from operations.
	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. These reclassifications did not have a significant impact on the condensed consolidated financial statements.

GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS (Policies)	9 Months Ended
	Sep. 30, 2013
Basis of Presentation	'
	Basis of Presentation
	The 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”). Due to the Transaction, the interim condensed consolidated financial statements are presented for Successor and Predecessor periods which relate to periods succeeding and preceding the Transaction, respectively. As a result of the Transaction, the condensed consolidated financial statements prior to and subsequent to the Transaction are not necessarily comparable. 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. These reclassifications did not have a significant impact on the condensed consolidated financial statements.
Unaudited Interim Financial Statements	'
	Unaudited Interim Financial Statements
	The accompanying condensed consolidated balance sheets and the condensed consolidated statements of comprehensive income (loss) and 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, reflect all adjustments (all of which are considered of a normal recurring nature) considered necessary to present fairly 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 and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	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, 2012 included in the Company’s registration statement on Form S-4 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, the estimated useful lives of the Company’s intangible assets, including content databases, determination of fair value of stock options included in stock-based compensation expense and allowances for sales returns and uncollectible accounts receivable. 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 registration statement on Form S-4 for the three and nine months ended September 30, 2013.
Guarantor Subsidiaries [Member]	'
Basis of Presentation	'
	Basis of Presentation
	The same accounting policies as described in the condensed consolidated financial statements are used by each entity in the condensed consolidating 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 consolidating 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.com Inc.’s consolidated U.S. tax return. In the condensed consolidating 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).
	Certain transfers of cash between subsidiaries and their parent companies and intercompany dividends are reflected as cash flows from financing activities in the accompanying condensed consolidating statements of cash flows. All other intercompany activity is reflected in cash flows from operations.
	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. These reclassifications did not have a significant impact on the condensed consolidated financial statements.
