The Company and Basis of Presentation	'
	1. The Company and Basis of Presentation
	Description of the business: Blucora, Inc. (the “Company” or “Blucora”) operates three primary businesses: an internet search business, an online tax preparation business and an e-commerce business. The Company’s Search business, InfoSpace, provides search services to distribution partners’ web properties as well as to the Company’s owned and operated properties. The Tax Preparation business consists of the operations of the TaxACT tax preparation online services and software business that the Company acquired on January 31, 2012. The E-Commerce business consists of the operations of Monoprice, Inc. (“Monoprice”), which the Company acquired on August 22, 2013, and is a provider of self-branded consumer electronics and accessories.
	On January 31, 2012, the Company acquired TaxACT Holdings, Inc. (“TaxACT Holdings”) and its wholly-owned subsidiary, TaxACT, Inc. (“TaxACT”), previously 2nd Story Software, Inc., which operates the TaxACT tax preparation online service and software business. The TaxACT business consists of an online tax preparation service for individuals, tax preparation software for individuals and professional tax preparers, and ancillary services. The majority of the TaxACT business’s revenue is generated by its online service at www.taxact.com.
	On August 22, 2013, the Company completed the acquisition of Monoprice pursuant to the terms of the Stock Purchase Agreement dated as of July 31, 2013. As a result of the Acquisition, Blucora owns 100% of Monoprice, an online provider of self-branded electronics and accessories for both consumers and businesses. Monoprice generates revenue primarily through its website, www.monoprice.com.
	Segments: The Company has three reporting segments: Search, Tax Preparation and E-Commerce. The Search segment is the InfoSpace business, the Tax Preparation segment is the TaxACT business, and the E-Commerce segment is the Monoprice business. Unless the context indicates otherwise, the Company uses the term “Search” to represent search services, the term “Tax Preparation” to represent services and products sold through the TaxACT business, and the term “E-Commerce” to represent products sold through the Monoprice business (see “Note 10: Segment Information”).
	Seasonality: Blucora’s Tax Preparation segment is highly seasonal. Revenue from the Company’s Tax Preparation segment tends to be highest during its first and second quarters as a result of significantly higher sales of income tax preparation services and products during the period from January through April. During the third and fourth quarter, the Tax Preparation segment typically reports losses because revenue from the segment is minimal while core operating expenses continue at relatively consistent levels.

	2. Summary of Significant Accounting Policies
	The Company’s critical accounting policies and methodologies during the quarter ended September 30, 2013 include those described in its Annual Report on Form 10-K for the year ended December 31, 2012, along with those presented below.
	Revenue recognition: The Company recognizes revenue when all four revenue recognition criteria have been met: persuasive evidence of an arrangement exists, the Company has delivered the product or performed the service, the fee is fixed or determinable, and collectability is probable. Determining whether and when these criteria have been satisfied involves exercising judgment and using estimates and assumptions that can have an impact on the timing and amount of revenue that the Company recognizes.
	The Company also evaluates whether revenue should be presented on a gross basis, which is the amount that a customer pays for the service or product, or on a net basis, which is the customer payment less amounts the Company pays to suppliers. In making that evaluation, the Company considers indicators such as whether the Company is the primary obligor in the arrangement and assumes the risks and rewards as a principal in the customer transaction, including the credit risk, and whether the Company can set the sales price and select suppliers. The accounting principles generally accepted in the United States of America (“GAAP”) clearly indicate that the evaluation of these factors, which at times can be contradictory, are subject to significant judgment and subjectivity.
	Search services revenue recognition: The majority of the Company’s revenues are generated from its web search services. The Search business does not generate its own search content for its web search services, but instead aggregates search content from a number of content providers. Some of these content providers, such as Google and Yahoo!, pay us to distribute their content, and those providers are referred to as “Search Customers”. The Company generates search services revenue when an end user of such services clicks on a paid search link provided by a Search Customer and displayed on a distribution partners’ web property or on one of the Company’s owned and operated web properties. The Search Customer that provided the paid search link receives a fee from the advertiser who paid for the click and the Search Customer pays the Company a portion of that fee. Revenue is recognized in the period in which the services are provided (i.e., when a paid search occurs) and is based on the amounts earned by and ultimately remitted to the Company. This revenue is recorded in the Search segment.
	Under the Company’s agreements with its Search Customers and its distribution partners, the Company is the primary obligor, separately negotiates each revenue or unit pricing contract independent of any revenue sharing arrangements, and assumes the credit risk for amounts invoiced to its Search Customers. For search services, the Company determines the paid search results, content, and information directed to its owned and operated websites and its distribution partners’ web properties.
	The Company earns revenue from its Search Customers by providing paid search results generated from its owned and operated web properties and from its distribution partners’ web properties based on separately negotiated and agreed-upon terms with each distribution partner. Consequently, the Company records search services revenue on a gross basis.
	Tax preparation revenue recognition: The Company derives service revenue from the sale of tax preparation online services, ancillary service offerings, packaged tax preparation software products, and multiple element arrangements that may include a combination of these items. Ancillary service offerings include tax preparation support services, data archive services, bank or reloadable pre-paid debit card services, e-filing services, and other value-added services. This revenue is recorded in the Tax Preparation segment.
	The Company’s Tax Preparation segment service revenue consists primarily of hosted tax preparation online services, tax preparation support services, data archive services, and e-filing services. The Company recognizes revenue from these services as the services are performed and the four revenue recognition criteria described above are met.
	The Company recognizes revenue from the sale of its packaged software products when legal title transfers. This is generally when its customers download products from the Web or when the products ship.
	The bank or reloadable prepaid debit card services are offered to taxpayers as an option to receive their tax refunds in the form of a prepaid bank card or to have the fees for the product and/or services purchased by the customers deducted from their refunds. Other value-added service revenue consists of revenue from revenue sharing and royalty arrangements with third party partners. Revenue for these transactions is recognized when the four revenue recognition criteria described above are met; for some arrangements that is upon filing and for other arrangements that is upon the Company’s determination of when collectability is probable.
	For products and/or services that consist of multiple elements, the Company must: (1) determine whether and when each element has been delivered; (2) determine the fair value of each element using the selling price hierarchy of vendor-specific objective evidence (“VSOE”) of fair value if available, third-party evidence (“TPE”) of fair value if VSOE is not available, and estimated selling price (“ESP”) if neither VSOE nor TPE is available; and (3) allocate the total price among the various elements based on the relative selling price method. Once the Company has allocated the total price among the various elements, it recognizes revenue when the revenue recognition criteria described above are met for each element.
	VSOE generally exists when the Company sells the deliverable separately. When VSOE cannot be established, the Company attempts to establish a selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. When the Company is unable to establish selling price using VSOE or TPE, it uses ESP in its allocation of arrangement consideration. ESP is the estimated price at which the Company would sell a product or service if it were sold on a stand-alone basis. The Company determines ESP for a product or service by considering multiple factors including, but not limited to, historical stand-alone sales, pricing practices, market conditions, competitive landscape, internal costs, and gross margin objectives.
	In some situations, the Company receives advance payments from its customers. The Company defers revenue associated with these advance payments and recognizes the allocated consideration for each element when the Company ships the products or performs the services, as appropriate. Advance payments related to data archive services are deferred and recognized over the related contractual term.
	E-Commerce revenue recognition: The Company recognizes product revenue from product sales when all four revenue recognition criteria, as outlined above, have been met. Because the Company either (i) has a general practice of refunding customer losses for products damaged while in-transit despite selling terms indicating title transfers at the point of shipment or (ii) has FOB-destination shipping terms specifically set out in certain arrangements, delivery is deemed to have occurred at the point in time when the product is received by the customer. All amounts billed to a customer in a sale transaction related to shipping and handling, if any, represents revenues earned for the goods provided, and these amounts have been classified as “product revenue”. Costs related to such shipping and handling billings are classified as “product cost of revenue”.
	The Company provides its customers with a thirty-day right of return. Return allowances, which reduce revenue, are estimated using historical experience.
	Cost of revenues: The Company records the cost of revenues for sales of products and services when the related revenue is recognized. Services cost of revenue consists of costs related to revenue sharing arrangements with our distribution partners, usage-based content fees, certain costs associated with the operation of our data centers that serve the Company’s Search and Tax Preparation businesses, including amortization of intangible assets, depreciation, personnel expenses (which include salaries, benefits and other employee related costs, and stock-based compensation expense), bandwidth costs, bank service fees, and royalties. Product cost of revenue includes product costs, inbound and outbound shipping and handling costs, packaging supplies, and provisions for inventory obsolescence. Shipping charges to receive products from the Company’s suppliers are included in inventory, and recognized as product cost of revenue upon sale of products to customers.
	Sales and marketing expenses: Sales and marketing expenses consist principally of marketing expenses associated with the Company’s TaxACT and Monoprice websites (which include the following channels: television, radio, online display and text, and email), the Company’s owned and operated web search properties (which consist of traffic acquisition, including the Company’s online marketing, which includes fees paid to search engines to drive traffic to an owned and operated website, agency fees, brand promotion expense and market research expense), personnel costs (which include salaries, benefits and other employee-related costs, and stock-based compensation expense) for personnel engaged in marketing and selling activities, and fulfillment expenses primarily associated with the Company’s E-Commerce business. Fulfillment includes direct operating expenses (including personnel costs) relating to the Company’s purchasing, customer and technical support, receiving, inspection and warehouse functions, as well as the cost of temporary help and contractors, and credit card processing fees.
	Inventories: Inventories, consisting of merchandise purchased for resale in the E-Commerce business, are accounted for using the first-in-first-out (“FIFO”) method of accounting, and are valued at the lower of cost or market. Inventory quantities on hand are reviewed regularly, and allowances are maintained for obsolete, slow moving, and nonsalable inventory.
	Business combinations and intangible assets including goodwill: The Company accounts for business combinations using the acquisition method and, accordingly, the identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. Goodwill is calculated as the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets. Identifiable intangible assets with finite lives are amortized over their useful lives. Acquisition-related costs, including advisory, legal, accounting, valuation, and other costs, are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date.
	Debt issuance costs and debt discount: Debt issuance costs and debt discounts are deferred and amortized as interest expense under the effective interest method over the contractual term of the related debt, adjusted for prepayments in the case of the Company’s credit facility (see “Note 8: Debt”).
	Debt issuance costs related to the Company’s Convertible Senior Notes (the “Notes”) issued in 2013 were allocated to the liability and equity components of the instrument. The debt issuance costs allocated to the liability component are amortized to interest expense through the earlier of the maturity date of the Notes or the date of conversion, if any. The debt issuance costs allocated to the equity component of the Notes were recorded as an offset to additional paid in capital (See “Note 8: Debt”).
	Supplier Concentration: A material part of Monoprice’s business is dependent on two vendors. During the period from August 22, 2013, the date of the acquisition, to September 30, 2013, these unrelated vendors accounted for $1.3 million or 16% and $742,000 and 9%, respectively, of Monoprice’s inventory purchases and at September 30, 2013 accounted for $1.1 million or 12% and $843,000 or 10%, respectively, of Monoprice’s related accounts payable, respectively.
	Impairment of Equity Method Investments: The Company evaluates its equity method investments for impairment whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of such investment may have experienced a decline in value. When evidence of an other-than-temporary decline has occurred, the Company compares the estimated fair value of the investment to the carrying value of the investment to determine whether an impairment has occurred.
	For the three months ended September 30, 2013, in connection with the Company’s review of its equity method investments for other than temporary impairment, the Company determined that its equity investment in a privately-held company had experienced a decline in value which was other than temporary, due to recurring losses from operations, significant personnel reductions and a change in the underlying business model. The Company’s impairment loss calculations require management to apply judgment in estimating future cash flows and assessing the probability of differing estimated outcomes. The Company assesses the fair value of its equity method investments using commonly accepted techniques to the extent applicable, and may use more than one method. Accordingly, this equity investment in a privately-held company with a carrying value of $3.7 million was written down to zero, resulting in a loss of $3.7 million, which was included in “other loss, net” in the Company’s condensed consolidated statements of operations for the three and nine month periods ended September 30, 2013.

	3. Acquisitions
	Monoprice. On August 22, 2013, the Company acquired all of the outstanding stock of Monoprice, an online provider of self-branded electronics and accessories for both consumers and businesses (see “Note 1: The Company and Basis of Presentation”). The preliminary acquisition consideration paid by the Company was equal to $183.3 million, which was funded from available cash and is subject to a final working capital adjustment during the fourth quarter of 2013. The acquisition was intended to diversify the Company’s business model and expand its operations. Under the acquisition method, assets acquired and liabilities assumed are recorded at their fair values as of the acquisition date. Any excess of the purchase price over the fair values of the net assets acquired is recorded as goodwill. Preliminary valuations are as follows (in thousands):
		Fair Value
	Tangible assets acquired	$	49,515
	Liabilities assumed		(23,122	)
	Identifiable net assets acquired	$	26,393
	Fair value adjustments to intangible assets
	Customer relationships	$	30,900
	Trade name		38,000
	Fair value of intangible assets acquired	$	68,900
	Purchase price:
	Cash paid	$	183,319
	Less identifiable net assets acquired		(26,393	)
	Plus deferred tax liability related to intangible assets		24,823
	Less fair value of intangible assets acquired		(68,900	)
	Excess of purchase price over net assets acquired, allocated to goodwill	$	112,849
	The preliminary fair value determinations for assets acquired and liabilities assumed for this acquisition was based upon a preliminary valuation and certain of our estimates and assumptions are subject to change as we obtain additional information for our estimates in future periods. The primary areas of the acquisition accounting that are not yet finalized relate to income and non-income based taxes, certain contingent liability matters, indemnification assets, and residual goodwill. The Company incurred acquisition costs of $646,000 and $698,000 in the three and nine months ended September 30, 2013, which were recognized in general and administrative expenses as incurred. The Company did not assume any equity awards or plans from Monoprice. Following the completion of the acquisition, the Company issued 27,152 options and 126,259 restricted stock units (“RSUs”), which are at levels consistent with other awards to Blucora subsidiary employees, and 243,750 performance-based restricted stock units (“PSUs”) to Monoprice’s employees.
	The Company’s estimates of the economic lives of the acquired intangible assets are two years for the business-to-consumer customer relationships, seven years for the business-to-business customer relationships, approximately six years for the personal property assets, and the trade name is estimated to have an indefinite-life. The Company plans to amortize the definite-lived intangible assets over their respective estimated lives. The goodwill and the trade name will be tested for impairment at least annually.
	The gross contractual amount of trade accounts receivable acquired was $3.2 million, which the Company expects to be completely collectible. The Company recorded a fair value of $1.3 million for deferred revenue, which Monoprice, prior to the acquisition, had recorded at $2.0 million as of the acquisition date.
	For the period from the August 22, 2013 acquisition date to September 30, 2013, the Company’s total revenues included $14.6 million in revenue from Monoprice’s sales. For the same period, Monoprice contributed $427,000 to the Company’s net loss.

	TaxACT. As described in “Note 1: The Company and Basis of Presentation”, on January 31, 2012, the Company acquired all of the outstanding stock of TaxACT Holdings and its wholly-owned subsidiary, TaxACT. The Company paid $287.5 million in cash for this acquisition, less certain transaction expenses, and subject to certain specified working capital adjustments. The acquisition of the TaxACT business was funded from the Company’s cash reserves and from the net proceeds of a $105 million credit facility (of which $100 million was drawn at the transaction’s close). For further discussion of the credit facility, see “Note 8: Debt”. The acquisition was intended to diversify the Company’s business model and expand its operations. The Company recorded $185.5 million in goodwill upon final valuation.

Fair Value Measures	'
	4. Fair Value Measures
	Certain financial assets and liabilities are remeasured and reported at fair value each reporting period. Fair value is 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. The Company measures its cash equivalents, available-for-sale investments, and derivative instruments at fair value. The cash equivalents and available-for-sale investments are valued within Level 2 in the fair value hierarchy because the Company values its cash equivalents and marketable securities using alternative pricing sources utilizing market observable inputs. The Company classifies its interest rate swap derivative within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. As more fully discussed in “Note 8: Debt”, the interest rate swap was terminated for break-even on September 10, 2013. The Company classifies the Warrant derivative (see “Note 5: Stock-Based Compensation”) within Level 3 because it is valued using the Black-Scholes valuation model, which has significant unobservable inputs. Those unobservable inputs reflect the Company’s assumptions, consistent with reasonably available assumptions made by other market participants. This valuation requires significant judgment.
	The fair value hierarchy of the Company’s financial assets and liabilities carried at fair value and measured on a recurring basis is as follows (in thousands):

The Company’s management considers the carrying values of accounts receivable, other receivables, inventory, prepaid expenses and other current assets, accounts payable, accrued expenses, and other current liabilities to approximate fair values primarily due to their short-term nature.

	In October 2011, the Company granted 200,000 stock options to a non-employee consultant who performed acquisition-related activities, and the award’s vesting was predicated on completing a “qualified acquisition” under the terms of the award. The completion of the acquisition of the TaxACT business on January 31, 2012 constituted a qualifying acquisition under the terms of the award, and the vesting of the award resulted in a charge of $903,000 to stock-based compensation expense in the nine months ended September 30, 2012, which was classified in general and administrative expenses.
	In May 2012, the Company granted 190,000 performance-based stock options to certain employees who perform acquisition-related activities, and the awards’ vestings are predicated on completing qualified acquisitions per the terms of the awards. No expense was recognized in 2012, as a qualified acquisition did not occur. The completion of the acquisition of Monoprice on August 22, 2013 constituted a qualifying acquisition under the terms of the awards, and the vestings of the awards resulted in a charge of $526,000 to stock-based compensation expense in the three and nine months ended September 30, 2013, which was classified in general and administrative expenses.
	In August 2011, the Company issued a Warrant to purchase one million shares of common stock, exercisable at a price of $9.62 per share. The Warrant was originally scheduled to expire on August 23, 2014, but the acquisition of the TaxACT business on January 31, 2012 was an event under the Warrant’s terms that extended the expiration date to the earlier of August 23, 2017 or the effective date of a change of control of the Company. The extension of the Warrant’s term was a modification that resulted in a $4.3 million charge to stock-based compensation expense in the first quarter 2012 equal to the increase in the Warrant’s fair value and was recognized in general and administrative expenses. Additionally, subsequent to the modification, the Company treated the award as a derivative instrument, and the modification date fair value previously recognized in paid in capital was classified as a current liability (See “Note 9: Derivative Instruments and Hedging Activities”).
	The total net shares issued for RSUs and MSUs vested, options exercised, and shares purchased pursuant to the ESPP during the three and nine months ended September 30, 2013 and 2012 is presented below (in thousands):

	6. Net Income (Loss) per Share
	Basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares outstanding plus the number of potentially dilutive shares outstanding during the period. Potentially dilutive shares consist of the incremental common shares issuable upon the exercise of outstanding stock options, the Warrant, vesting of unvested RSUs, MSUs, and PSUs, and the impact of shares that could be issued upon conversion or maturity of our convertible debt. Potentially dilutive shares are excluded from the computation of earnings per share if their effect is antidilutive.
	The weighted average dilutive and anti-dilutive shares for the three and nine months ended September 30, 2013 and 2012 are as follows (in thousands):

	As more fully discussed in “Note 8: Debt”, in March 2013, we issued Convertible Senior Notes (the “Notes”) maturing in April 2019. The Company intends, upon conversion or maturity of the Notes, to satisfy any conversion premium by issuing shares of our common stock. Due to the cash settlement feature of the principal amount of the Notes, the Company only includes the impact of the premium feature in its diluted earnings per common share calculation when the average stock price exceeds the conversion price of the Notes, which did not occur for the three or nine months ended September 30, 2013.

Debt	'
	8. Debt
	Term Debt. On January 31, 2012, in conjunction with closing the Company’s acquisition of the TaxACT business, TaxACT entered into an agreement with a syndicate of lenders for a $105 million credit facility, consisting of $95 million term loan and up to $10 million under a revolving credit facility. On January 31, 2012, TaxACT borrowed $95 million of term debt with an original maturity of January 31, 2017 and $5 million under the revolving credit facility. A portion of any excess cash flows, as the term is defined in the credit agreement, were to be used to make a mandatory prepayment on the term loan within sixty days of June 30th, beginning June 30, 2013, and in each succeeding year, in the event that the leverage ratio is more than two-to-one on June 30th of that year. Amounts outstanding under the term loan could be prepaid without penalty. During 2012, TaxACT repaid an aggregate of $25.5 million of the debt, including the balance of revolving credit facility. In April 2013, TaxACT repaid an additional $10.0 million of the outstanding debt, and in August 2013, the remaining amount of $64.5 million was repaid in connection with the refinancing of this credit agreement as discussed further below.
	The interest rate on amounts borrowed under the term loan and the revolving loan was variable and payable as of the end of each interest period, based upon, at the election of TaxACT, the Alternate Base Rate or the LIBOR Rate, plus the Applicable Margin (as such terms are defined in the credit agreement). The Applicable Margin was dependent on the consolidated Total Leverage Ratio (as defined in the credit agreement) of TaxACT Holdings and ranged from 2.0% to 3.5% for borrowings tied to the Alternative Base Rate and 3.0% to 4.5% for borrowings tied to the LIBOR Rate.
	Additionally, the Company was required to hedge a portion of the interest rate risk associated with the term debt 90 days after its inception, and that requirement was met on May 1, 2012 by the purchase of an interest rate swap with a financial institution which fixed the LIBOR Rate portion at 0.85% for $37.5 million of the amount outstanding under the term loan. The swap was terminated for break-even on September 10, 2013.
	Credit Facility. On August 30, 2013, TaxACT and TaxACT Holdings entered into an agreement with a syndicate of lenders for the purpose of refinancing the previous credit agreement entered into by TaxACT and TaxACT Holdings on January 31, 2012 on more favorable terms. The new credit facility consists of revolving credit loans, up to $10.0 million in swingline loans, and up to $5.0 million under a letter of credit, which in the aggregate represent a $100.0 million revolving credit commitment that reduces to $90.0 million on August 30, 2014, to $80.0 million on August 30, 2015, and to $70.0 million on August 30, 2016. The final maturity date of the credit facility is August 30, 2018. TaxACT’s obligations under the credit facility are guaranteed by TaxACT Holdings, and are secured by the assets of the TaxACT business and the TaxACT equity owned by TaxACT Holdings.
	TaxACT initially borrowed approximately $65.4 million under the revolving credit loans, which was used to pay off the $64.5 million principal balance of the term loan as described above and to pay accrued interest, certain expenses and fees related to the agreement. The Company has the right to permanently reduce, without premium or penalty, (i) the entire credit facility at any time or (ii) portions of the credit facility, from time to time, in an aggregate principal amount not less than $3 million or any whole multiple of $1 million in excess thereof. The interest rate on amounts borrowed under the credit facility is variable and payable as of the end of each interest period, based upon, at the election of TaxACT, either (i) LIBOR plus a margin of between 1.75% and 2.5%, or (ii) a Base Rate plus a margin of between 0.75% and 1.5%, in each case with the applicable margin within the range dependent upon TaxACT’s ratio of leverage to EBITDA over the previous four quarters. The credit facility includes financial and operating covenants with respect to certain ratios, including (a) leverage ratio and (b) fixed charge coverage ratio, which are defined further in the agreement, as well as certain restrictions on TaxACT’s payments to the Company. As of September 30, 2013, the Company was in compliance with all of the financial and operating covenants. As of September 30, 2013, the credit facility’s gross carrying value of $65.4 million approximates its fair value as it is a variable rate instrument and the current applicable margin approximates current market conditions.
	In accordance with the relevant accounting guidance, the Company performed an analysis by creditor to determine whether the refinancing would be recorded as an extinguishment or a modification of debt, and as a result of this analysis, recognized a loss on partial extinguishment of debt comprised of the following (in thousands):
	Fees paid to creditors in connection with the refinance, including arrangement fee classified as extinguishment		$	567
	Deferred financing costs on extinguished debt			726
	Debt discount on extinguished debt			300
	Total		$	1,593
	In accordance with the debt extinguishment accounting guidance, the Company recorded $28,000 in deferred debt issuance costs, which will be amortized over the term of the new credit facility using the effective interest method as an adjustment to interest expense. The Company also determined that the remaining portion of the refinancing was a modification under the related accounting guidance, and the Company determined a new effective interest rate based on the carrying amount of the original debt and the revised cash flows. Approximately $606,000, which is comprised of $429,000 in deferred financing costs and $177,000 in unamortized debt discount related to the prior credit agreement, will be amortized as an adjustment to interest expense over the remaining term of the new credit facility using the effective interest method. Similarly, additional creditor-related fees incurred of $92,000 related to the modification will be amortized over the term of the new debt using the effective interest method.
	Convertible Senior Notes. On March 15, 2013, the Company issued $201.25 million aggregate principal amount of its 4.25% Convertible Senior Notes (the “Notes”), inclusive of the underwriters’ exercise in full of their over-allotment option of $26.25 million. The Notes mature on April 1, 2019 unless earlier purchased, redeemed, or converted in accordance with the terms and bear interest at a rate of 4.25% per year, which began to accrue on March 15, 2013 and is payable semi-annually in arrears on April 1 and October 1 of each year beginning on October 1, 2013. Based upon the above, annual interest payments for fiscal year 2013, fiscal years 2014 through 2018, and fiscal year 2019 will be $4.7 million, $8.6 million, and $4.3 million, respectively. The Company received net proceeds from the offering of approximately $194.8 million after adjusting for debt issuance costs, including the underwriting discount.
	The Notes were issued under an indenture dated March 15, 2013 (the “Indenture”) by and between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee. There are no financial or operating covenants relating to the Notes.
	On or before June 30, 2013, holders could not convert the Notes under any circumstances. After June 30, 2013 and prior to the close of business on the business day immediately preceding October 1, 2018, holders may convert all or a portion of the Notes at their option, in multiples of $1,000 principal amount, only under the following circumstances:
		•		during any fiscal quarter commencing after the calendar quarter ending on June 30, 2013 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
		•		during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of the Notes for each trading day of the measurement period was less than 98% of the product of the last reported sales price of the Company’s common stock and the conversion rate on each trading day;
		•		if the Company calls any or all of the Notes for redemption;
		•		upon the occurrence of specified corporate events, including a merger or a sale of all or substantially all of the Company’s assets.
	On or after October 1, 2018 until the close of business on the second scheduled trading day immediately preceding the maturity date of April 1, 2019, holders may convert their Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.
	The conversion rate for the Notes is initially 46.1723 shares per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $21.66 per share of the Company’s common stock). The conversion rate is subject to customary adjustment for certain events as described in the Indenture.
	At the time the Company issued the Notes, the Company was only permitted to settle conversions with shares of its common stock. The Company received shareholder approval at its annual meeting in May 2013 to allow for “flexible settlement”, which provides the Company with the option to settle conversions in cash, shares of common stock, or any combination thereof. The Company’s intention is to satisfy conversion of the Notes with cash for the principal amount of the debt and shares of common stock for any related conversion premium.
	The Company may not redeem the Notes prior to April 6, 2016. After April 6, 2016, the Company may, at its option, redeem for cash all or part of the Notes plus accrued and unpaid interest up to, but not including the redemption date. If the Company undergoes a fundamental change, (as described in the Indenture), subject to certain conditions, holders may require the Company to repurchase for cash all or part of their Notes in principal amounts of $1,000 or an integral multiple thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. However, if a fundamental change occurs and a holder elects to convert the Notes, the Company will, under certain circumstances, increase the applicable conversion rate for the Notes surrendered for conversion by a number of additional shares of common stock based on the date on which the fundamental change occurs or becomes effective and the price paid per share of the Company’s common stock in the fundamental change as specified in the Indenture.
	The Notes are unsecured and unsubordinated obligations of the Company and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes, and equal in right of payment to any of the Company’s existing and future unsecured indebtedness that is not subordinated. The Notes are effectively junior in right of payment to any of the Company’s secured indebtedness (to the extent of the value of assets securing such indebtedness) and structurally junior to all existing and future indebtedness and other liabilities, including trade payables, of the Company’s subsidiaries. The Indenture does not limit the amount of debt that the Company or its subsidiaries may incur, including senior secured indebtedness.
	The Notes may be settled in combination of cash or shares of common stock given the flexible settlement option. As a result, the Notes contain liability and equity components which were bifurcated and accounted for separately. The liability component of the Notes, as of the issuance date, was calculated by estimating the fair value of a similar liability issued at a 6.5% effective interest rate, which was determined by considering the rate of return investors would require in the Company’s debt structure. The amount of the equity component was calculated by deducting the fair value of the liability component from the principal amount of the Notes, resulting in the initial recognition of $22.3 million as the debt discount recorded in additional paid in capital for the Notes. The carrying amount of the Notes will be accreted to the principal amount over the remaining term to maturity and the Company will record a corresponding interest expense.
	As of September 30, 2013, the net carrying amount of the Notes was as follows (in thousands):
			September 30,
			2013
	Principal Amount		$	201,250
	Unamortized discount			(20,525	)
	Net Carrying Value		$	180,725
	The Company incurred debt issuance costs of $6.4 million related to the Notes and allocated $5.7 million of debt issuance costs to the liability component of the Notes. These costs will be amortized to interest expense over the six year term of the Notes or the date of conversion, if any.
	The following table sets forth total interest expense related to the Notes (in thousands):
			Three months ended			Nine months ended
			September 30, 2013			September 30, 2013
	Contractual interest expense (Cash)		$	2,139		$	4,657
	Amortization of debt issuance costs (Non-cash)			216			465
	Accretion of debt discount (Non-cash)			843			1,816
	Total interest expense		$	3,198		$	6,938
	Effective interest rate of the liability component			7.32	%		7.32	%
	The fair value of the principal amount of the Notes as of September 30, 2013 was $252.8 million, based on the last trading price as of that date.
	Line of Credit. Monoprice has a short-term credit line up to $8.0 million borrowing capacity, which matures on July 31, 2014. The line of credit bears interest at an average monthly LIBOR rate plus 2.25%. The outstanding balance of the line of credit was zero at the date of acquisition on August 22, 2013 and at September 30, 2013. This line of credit is collateralized by the general business assets of Monoprice. Monoprice is subject to restrictive covenants related to the line-of-credit agreement pertaining to maintenance of current ratio, debt service coverage ratio, and debt-to-worth ratio.

	9. Derivative Instruments and Hedging Activities
	The Company recognizes derivative instruments as either assets or liabilities on its unaudited condensed consolidated balance sheets at fair value. The Company records changes in the fair value of the derivative instruments as gains or losses in the unaudited condensed consolidated statements of comprehensive income (loss) in other loss, net, or to accumulated other comprehensive income (loss) in the unaudited condensed consolidated balance sheets.
	The presentation of derivative instruments on the unaudited condensed consolidated balance sheets is summarized below (in thousands):
				Fair value of derivative
				instruments
		Balance sheet location		As of				As of
				September				December 31,
				30, 2013				2012
	Derivative liabilities
	Derivative designated as a hedging instrument:
	Interest rate contract (interest rate swap)	Current liabilities - derivative instruments		$	—			$	410
	Derivative not designated as a hedging instrument:
	Equity contract (the Warrant)	Current liabilities - derivative instruments			14,495				8,564
	Total derivative liabilities			$	14,495			$	8,974
	The derivative instrument in a hedging relationship had no effect on income for any and all periods presented, as it did not have any hedging ineffectiveness. As noted in “Note 8: Debt”, above, the interest rate swap was terminated at break-even on September 10, 2013.
	The effect of the derivative instrument not designated as hedging instruments on income is summarized below for the three and nine months ended September 30, 2013 and 2012 (in thousands):
				Loss recognized in other loss, net
				Three months ended								Nine months ended
	Derivative not designated as hedging	Statement of Comprehensive Income		September 30,				September 30,				September 30,		September 30,
	instrument	(Loss) location		2013				2012				2013		2012
	Equity contract (the Warrant)	Other loss, net		$	3,956			$	4,335			$	5,931	$	4,274
	At September 30, 2013, the estimated fair value of the Warrant derivative instrument was $14.5 million. The Company values the Warrant, classified within Level 3, by using the Black-Scholes option pricing model which takes into account a variety of factors, including historical stock price volatility, risk-free interest rates, remaining maturity, and the closing price of our common stock. The Company believes the assumption that has the greatest impact on the determination of fair value is the closing price of our common stock.
	The following table illustrates the potential impact of a change in stock price on the fair value of the derivative at September 30, 2013:
		-10%				September 30,				10%
						2013
						closing stock price
	Effect of a 10% change in stock price:
	Variable changed
	Closing stock price	$	20.68			$	22.98			$	25.28
	Estimated fair value (in thousands)	$	12,365							$	16,661
	If our stock price increased or decreased by 10% (all other Black-Scholes variables held constant) our reported net income for the nine months ending September 30, 2013 would have been $23.4 million and $27.7 million, respectively.

	In the three and nine months ended September 30, 2013, the Company revised the presentation of its Consolidated Statement of Comprehensive Income (Loss) as outlined below:
	As a result of the Monoprice acquisition in August 2013, the Company revised the classification of credit cards fees previously reported in services cost of revenue to sales and marketing. The Company assessed the related materiality of the reclassification and concluded that it is immaterial to any of our previously issued financial statements and therefore, have revised the three and nine months ended September 30, 2012 from the amounts previously reported in that period’s quarterly report on Form 10-Q to conform with the 2013 presentation. The revision of classification had no effect on our reported net revenues, operating income (loss) or cash flows for the three or nine months ended September 30, 2013 or 2012.

Recent Accounting Pronouncements	'
	13. Recent Accounting Pronouncements
	Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all recent ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.
	In February 2013, the FASB issued an update to the authoritative guidance related to the reporting of amounts reclassified out of accumulated other comprehensive income. This new requirement about presenting information about amounts reclassified out of accumulated other comprehensive income and their corresponding effect on net income will present, in one place, information about significant amounts reclassified and, in some cases, cross-references to related footnote disclosures. The Company adopted this guidance in the first quarter of 2013, and the adoption of these disclosure requirements did not have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued guidance on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance is effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2013
Accounting Policies [Abstract]	'
Revenue Recognition	'
	Revenue recognition: The Company recognizes revenue when all four revenue recognition criteria have been met: persuasive evidence of an arrangement exists, the Company has delivered the product or performed the service, the fee is fixed or determinable, and collectability is probable. Determining whether and when these criteria have been satisfied involves exercising judgment and using estimates and assumptions that can have an impact on the timing and amount of revenue that the Company recognizes.
	The Company also evaluates whether revenue should be presented on a gross basis, which is the amount that a customer pays for the service or product, or on a net basis, which is the customer payment less amounts the Company pays to suppliers. In making that evaluation, the Company considers indicators such as whether the Company is the primary obligor in the arrangement and assumes the risks and rewards as a principal in the customer transaction, including the credit risk, and whether the Company can set the sales price and select suppliers. The accounting principles generally accepted in the United States of America (“GAAP”) clearly indicate that the evaluation of these factors, which at times can be contradictory, are subject to significant judgment and subjectivity.
Search Services Revenue Recognition	'
	Search services revenue recognition: The majority of the Company’s revenues are generated from its web search services. The Search business does not generate its own search content for its web search services, but instead aggregates search content from a number of content providers. Some of these content providers, such as Google and Yahoo!, pay us to distribute their content, and those providers are referred to as “Search Customers”. The Company generates search services revenue when an end user of such services clicks on a paid search link provided by a Search Customer and displayed on a distribution partners’ web property or on one of the Company’s owned and operated web properties. The Search Customer that provided the paid search link receives a fee from the advertiser who paid for the click and the Search Customer pays the Company a portion of that fee. Revenue is recognized in the period in which the services are provided (i.e., when a paid search occurs) and is based on the amounts earned by and ultimately remitted to the Company. This revenue is recorded in the Search segment.
	Under the Company’s agreements with its Search Customers and its distribution partners, the Company is the primary obligor, separately negotiates each revenue or unit pricing contract independent of any revenue sharing arrangements, and assumes the credit risk for amounts invoiced to its Search Customers. For search services, the Company determines the paid search results, content, and information directed to its owned and operated websites and its distribution partners’ web properties.
	The Company earns revenue from its Search Customers by providing paid search results generated from its owned and operated web properties and from its distribution partners’ web properties based on separately negotiated and agreed-upon terms with each distribution partner. Consequently, the Company records search services revenue on a gross basis.
Tax Preparation Revenue Recognition	'
	Tax preparation revenue recognition: The Company derives service revenue from the sale of tax preparation online services, ancillary service offerings, packaged tax preparation software products, and multiple element arrangements that may include a combination of these items. Ancillary service offerings include tax preparation support services, data archive services, bank or reloadable pre-paid debit card services, e-filing services, and other value-added services. This revenue is recorded in the Tax Preparation segment.
	The Company’s Tax Preparation segment service revenue consists primarily of hosted tax preparation online services, tax preparation support services, data archive services, and e-filing services. The Company recognizes revenue from these services as the services are performed and the four revenue recognition criteria described above are met.
	The Company recognizes revenue from the sale of its packaged software products when legal title transfers. This is generally when its customers download products from the Web or when the products ship.
	The bank or reloadable prepaid debit card services are offered to taxpayers as an option to receive their tax refunds in the form of a prepaid bank card or to have the fees for the product and/or services purchased by the customers deducted from their refunds. Other value-added service revenue consists of revenue from revenue sharing and royalty arrangements with third party partners. Revenue for these transactions is recognized when the four revenue recognition criteria described above are met; for some arrangements that is upon filing and for other arrangements that is upon the Company’s determination of when collectability is probable.
	For products and/or services that consist of multiple elements, the Company must: (1) determine whether and when each element has been delivered; (2) determine the fair value of each element using the selling price hierarchy of vendor-specific objective evidence (“VSOE”) of fair value if available, third-party evidence (“TPE”) of fair value if VSOE is not available, and estimated selling price (“ESP”) if neither VSOE nor TPE is available; and (3) allocate the total price among the various elements based on the relative selling price method. Once the Company has allocated the total price among the various elements, it recognizes revenue when the revenue recognition criteria described above are met for each element.
	VSOE generally exists when the Company sells the deliverable separately. When VSOE cannot be established, the Company attempts to establish a selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. When the Company is unable to establish selling price using VSOE or TPE, it uses ESP in its allocation of arrangement consideration. ESP is the estimated price at which the Company would sell a product or service if it were sold on a stand-alone basis. The Company determines ESP for a product or service by considering multiple factors including, but not limited to, historical stand-alone sales, pricing practices, market conditions, competitive landscape, internal costs, and gross margin objectives.
	In some situations, the Company receives advance payments from its customers. The Company defers revenue associated with these advance payments and recognizes the allocated consideration for each element when the Company ships the products or performs the services, as appropriate. Advance payments related to data archive services are deferred and recognized over the related contractual term.
E-Commerce Revenue Recognition	'
	E-Commerce revenue recognition: The Company recognizes product revenue from product sales when all four revenue recognition criteria, as outlined above, have been met. Because the Company either (i) has a general practice of refunding customer losses for products damaged while in-transit despite selling terms indicating title transfers at the point of shipment or (ii) has FOB-destination shipping terms specifically set out in certain arrangements, delivery is deemed to have occurred at the point in time when the product is received by the customer. All amounts billed to a customer in a sale transaction related to shipping and handling, if any, represents revenues earned for the goods provided, and these amounts have been classified as “product revenue”. Costs related to such shipping and handling billings are classified as “product cost of revenue”.
	The Company provides its customers with a thirty-day right of return. Return allowances, which reduce revenue, are estimated using historical experience.
Cost of Revenues	'
	Cost of revenues: The Company records the cost of revenues for sales of products and services when the related revenue is recognized. Services cost of revenue consists of costs related to revenue sharing arrangements with our distribution partners, usage-based content fees, certain costs associated with the operation of our data centers that serve the Company’s Search and Tax Preparation businesses, including amortization of intangible assets, depreciation, personnel expenses (which include salaries, benefits and other employee related costs, and stock-based compensation expense), bandwidth costs, bank service fees, and royalties. Product cost of revenue includes product costs, inbound and outbound shipping and handling costs, packaging supplies, and provisions for inventory obsolescence. Shipping charges to receive products from the Company’s suppliers are included in inventory, and recognized as product cost of revenue upon sale of products to customers.
Sales and Marketing Expenses	'
	Sales and marketing expenses: Sales and marketing expenses consist principally of marketing expenses associated with the Company’s TaxACT and Monoprice websites (which include the following channels: television, radio, online display and text, and email), the Company’s owned and operated web search properties (which consist of traffic acquisition, including the Company’s online marketing, which includes fees paid to search engines to drive traffic to an owned and operated website, agency fees, brand promotion expense and market research expense), personnel costs (which include salaries, benefits and other employee-related costs, and stock-based compensation expense) for personnel engaged in marketing and selling activities, and fulfillment expenses primarily associated with the Company’s E-Commerce business. Fulfillment includes direct operating expenses (including personnel costs) relating to the Company’s purchasing, customer and technical support, receiving, inspection and warehouse functions, as well as the cost of temporary help and contractors, and credit card processing fees.
Inventories	'
	Inventories: Inventories, consisting of merchandise purchased for resale in the E-Commerce business, are accounted for using the first-in-first-out (“FIFO”) method of accounting, and are valued at the lower of cost or market. Inventory quantities on hand are reviewed regularly, and allowances are maintained for obsolete, slow moving, and nonsalable inventory.
Business Combinations and Intangible Assets Including Goodwill	'
	Business combinations and intangible assets including goodwill: The Company accounts for business combinations using the acquisition method and, accordingly, the identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. Goodwill is calculated as the excess of the purchase price over the fair value of net assets, including the amount assigned to identifiable intangible assets. Identifiable intangible assets with finite lives are amortized over their useful lives. Acquisition-related costs, including advisory, legal, accounting, valuation, and other costs, are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date.
Debt Issuance Costs and Debt Discount	'
	Debt issuance costs and debt discount: Debt issuance costs and debt discounts are deferred and amortized as interest expense under the effective interest method over the contractual term of the related debt, adjusted for prepayments in the case of the Company’s credit facility (see “Note 8: Debt”).
	Debt issuance costs related to the Company’s Convertible Senior Notes (the “Notes”) issued in 2013 were allocated to the liability and equity components of the instrument. The debt issuance costs allocated to the liability component are amortized to interest expense through the earlier of the maturity date of the Notes or the date of conversion, if any. The debt issuance costs allocated to the equity component of the Notes were recorded as an offset to additional paid in capital (See “Note 8: Debt”).
Supplier Concentration	'
	Supplier Concentration: A material part of Monoprice’s business is dependent on two vendors. During the period from August 22, 2013, the date of the acquisition, to September 30, 2013, these unrelated vendors accounted for $1.3 million or 16% and $742,000 and 9%, respectively, of Monoprice’s inventory purchases and at September 30, 2013 accounted for $1.1 million or 12% and $843,000 or 10%, respectively, of Monoprice’s related accounts payable, respectively.
Impairment of Equity Method Investments	'
	Impairment of Equity Method Investments: The Company evaluates its equity method investments for impairment whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of such investment may have experienced a decline in value. When evidence of an other-than-temporary decline has occurred, the Company compares the estimated fair value of the investment to the carrying value of the investment to determine whether an impairment has occurred.
	For the three months ended September 30, 2013, in connection with the Company’s review of its equity method investments for other than temporary impairment, the Company determined that its equity investment in a privately-held company had experienced a decline in value which was other than temporary, due to recurring losses from operations, significant personnel reductions and a change in the underlying business model. The Company’s impairment loss calculations require management to apply judgment in estimating future cash flows and assessing the probability of differing estimated outcomes. The Company assesses the fair value of its equity method investments using commonly accepted techniques to the extent applicable, and may use more than one method. Accordingly, this equity investment in a privately-held company with a carrying value of $3.7 million was written down to zero, resulting in a loss of $3.7 million, which was included in “other loss, net” in the Company’s condensed consolidated statements of operations for the three and nine month periods ended September 30, 2013.
Fair Value Measures, Policy	'
	Certain financial assets and liabilities are remeasured and reported at fair value each reporting period. Fair value is 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. The Company measures its cash equivalents, available-for-sale investments, and derivative instruments at fair value. The cash equivalents and available-for-sale investments are valued within Level 2 in the fair value hierarchy because the Company values its cash equivalents and marketable securities using alternative pricing sources utilizing market observable inputs. The Company classifies its interest rate swap derivative within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. As more fully discussed in “Note 8: Debt”, the interest rate swap was terminated for break-even on September 10, 2013. The Company classifies the Warrant derivative (see “Note 5: Stock-Based Compensation”) within Level 3 because it is valued using the Black-Scholes valuation model, which has significant unobservable inputs. Those unobservable inputs reflect the Company’s assumptions, consistent with reasonably available assumptions made by other market participants. This valuation requires significant judgment.
Net Income (Loss) per Share, Policy	'
	Basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares outstanding plus the number of potentially dilutive shares outstanding during the period. Potentially dilutive shares consist of the incremental common shares issuable upon the exercise of outstanding stock options, the Warrant, vesting of unvested RSUs, MSUs and PSUs, and the impact of shares that could be issued upon conversion or maturity of our convertible debt. Potentially dilutive shares are excluded from the computation of earnings per share if their effect is antidilutive.
Derivative Instruments and Hedging Activities, Policy	'
	The Company recognizes derivative instruments as either assets or liabilities on its unaudited condensed consolidated balance sheets at fair value. The Company records changes in the fair value of the derivative instruments as gains or losses in the unaudited condensed consolidated statements of comprehensive income (loss) in other loss, net, or to accumulated other comprehensive income (loss) in the unaudited condensed consolidated balance sheets.
Segment Information, Policy	'
	The Company does not allocate certain general and administrative costs (including personnel and overhead costs), stock-based compensation, depreciation, amortization of intangible assets, other loss, net and income tax expense to the reportable segments. Such amounts are reflected in the table under the heading “Corporate-level activity.” The Company does not account for, and does not report to management, its assets or capital expenditures by segment other than goodwill and intangible assets used for impairment analysis purposes.
