Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of KAYAK Software Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statement of operations, of comprehensive income, of changes in stockholders equity and of cash flows present fairly, in all material respects, the financial position of KAYAK Software Corporation and its subsidiaries at December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

1. Organization

The Company was incorporated in Delaware on January 14, 2004 under the name of Travel Search Company, Inc. On August 17, 2004, we officially changed our name to KAYAK Software Corporation (“KAYAK”). We operate KAYAK.com and other travel websites and mobile applications that allow people to search for rates and availability for airline tickets, hotel rooms, rental cars, and other travel-related services across hundreds of websites and provide choices on where to book. As used in this report, the terms “we,” “us,” “our,” “KAYAK” and the “Company” mean KAYAK Software Corporation and its subsidiaries, unless the context indicates another meaning.

On July 25, 2012, we completed our initial public offering, or IPO, in which we issued and sold 4,025,000 shares of Class A common stock at an offering price of $26.00 per share. We received net proceeds of $94,213 after deducting underwriting discounts and commissions and issuance costs of approximately $4,112. In connection with our IPO, we also entered into private placement transactions with existing stockholders pursuant to which we issued and sold 231,695 shares of our Class A common stock at a price of $26.00 per share and issued 308,032 shares of our Class A common stock for no consideration.

On November 8, 2012, we entered into an Agreement and Plan of Merger, or Merger Agreement, to be acquired by priceline.com Incorporated (NASDAQ: PCLN), or Priceline. Under the terms of the Merger Agreement KAYAK will merge with and into a wholly owned subsidiary of Priceline.

At the effective time of the merger, each share of KAYAK Class A and Class B common stock issued and outstanding immediately prior to the effective time will, at the election of the holder and subject to proration as set forth in the Merger Agreement, be converted into the right to receive either (i) $40.00 per share of KAYAK Class A and Class B common stock or (ii) a fraction of a share of Priceline common stock. The number of shares of Priceline common stock issued in consideration for the Class A and Class B common stock will be based upon a formula as set forth in the Merger Agreement.

The merger was unanimously approved by the respective Boards of Directors of KAYAK and Priceline and the Board of Directors of KAYAK recommended that KAYAK’s stockholders approve the proposed transaction.

On March 4, 2013, KAYAK stockholders voted to approve the adoption of the previously announced Agreement and Plan of Merger between KAYAK, priceline.com and Produce Merger Sub Inc., a wholly owned subsidiary of priceline.com. Approximately 96% of the total voting power of KAYAK's outstanding shares of Class A common stock and Class B common stock as of the January 24, 2012, the record date for the special meeting of stockholders, were voted in favor of the adoption of the Agreement and Plan of Merger.

On March 13, 2013, the UK Office of Fair Trading (“OFT”) announced that that the administrative deadline for the OFT's review of the merger of KAYAK with priceline.com is expected to be in May 2013. The closing of the merger will take place once the remaining conditions to closing (including the receipt of all required regulatory approvals) have been satisfied.

The Merger Agreement contains certain termination rights for both KAYAK and Priceline and further provides that, upon termination of the Merger Agreement under certain circumstances, KAYAK may be obligated to pay Priceline a termination fee of $52,700.

2. Summary of Significant Accounting Policies

Significant Estimates and Judgments

The preparation of financial statements in conformity with GAAP in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these financial statements include the provision for uncollectible accounts, estimates used to determine the fair value of our common stock, preferred stock, put option, stock-based compensation and preferred stock warrants, recoverability of our net deferred tax assets and the fair value of long lived assets, goodwill, and litigation liabilities. Changes in estimates are recorded in the period in which they become known. We base

estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. Operating results of acquired businesses are included in the consolidated statements of operations from the date of acquisition. All intercompany accounts and transactions have been eliminated. We have reclassified certain prior period amounts to conform to our current period presentation.

Foreign Currency Translation

Assets and liabilities for our international operations are translated to U.S. dollars at current exchange rates in effect at the balance sheet date. Income and expense accounts are translated at average exchange rates in effect during the year. Resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income.

Segments

We have one operating segment for financial reporting purposes: travel search.

Revenue Recognition

KAYAK’s services are free for travelers. We earn revenues by sending referrals to travel suppliers and online travel agents, (OTAs) after a traveler selects a specific itinerary (distribution revenues), and through advertising placements on our websites and mobile applications (advertising revenues).

We recognize distribution revenues upon completion of the referral, provided that our fees are fixed and determinable, there is persuasive evidence of an arrangement and collection is reasonably assured. Advertising revenues are recognized when a traveler clicks on an advertisement that a customer has placed on our website or mobile application or when we display an advertisement.

Distribution Revenues

We earn distribution revenues by sending qualified leads to travel suppliers and OTAs and by facilitating bookings directly through our websites and mobile applications. After a traveler has entered a query on our website, reviewed the results, and decided upon a specific itinerary, we send the user directly into the travel supplier's or OTA's purchase process to complete the transaction. In many cases, users may now complete bookings with the travel supplier or OTA without leaving our websites and mobile applications. Travel suppliers and OTAs have the flexibility to pay us either when these qualified leads click on a query result at a set cost per click, or CPC basis, or when they purchase a travel product either through us or on the travel supplier or OTA website which we refer to as a cost per acquisition, or CPA, basis. We separately negotiate and enter into our distribution agreements, and these agreements set forth the payment terms for the applicable travel supplier or OTA.

Advertising Revenues

providers. Generally, our advertisers pay us on a CPC basis, which means advertisers pay us only when someone clicks on one of their advertisements, or on a cost per thousand impression basis, or CPM. Paying on a CPM basis means that advertisers pay us based on the number of times their advertisements appear on our websites or mobile applications.

Concentrations of Credit Risk

Financial instruments that subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. Our cash and cash equivalents and marketable securities are primarily held in one financial institution that we believe to be of high credit quality.

Five significant customers accounted for the following percentages of total revenues:



	Years Ended December 31,
	2012	2011	2010
Customer A	26%	24%	25%
Customer B	10%	8%	6%
Customer C	7%	12%	18%
Customer D	7%	6%	6%
Customer E	6%	6%	8%

Amounts due from these significant customers were:



	December 31,
	2012		2011
Customer A	$	5,480	$	7,354
Customer B	2,679		2,732
Customer C	2,718		4,242
Customer D	503		1,779
Customer E	42		1,045

We believe significant customer amounts outstanding at December 31, 2012 and 2011 are collectible.

Cost of Revenues

Cost of revenues consists primarily of expenses incurred related to airfare query costs, data center costs and related bandwidth charges. All costs of revenues are expensed as incurred.

Marketing

Marketing expenses are comprised primarily of costs of search engine and other digital marketing, brand advertising, affiliate referral fees, and public relations. All marketing costs are expensed as incurred.

Stock-Based Compensation

We estimate the value of stock option awards on the date of grant using the Black-Scholes option-pricing model (the Black-Scholes model). The determination of the fair value of stock option awards on the date of grant is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the term of the awards, expected term, risk-free interest rate, expected dividends and expected forfeiture rates. The forfeiture rate is estimated using historical option cancellation information, adjusted for anticipated changes in exercise and employment termination behavior. Outstanding awards do not contain market or performance conditions and therefore, we recognize stock-based compensation expense on a straight-line basis over the requisite service period.

services received. The fair value of the unvested portion of the options granted to non-employees is re-measured each period. The resulting increase or decrease in value, if any, is recognized during the period the related services are rendered. The fair value of each non-employee stock-based compensation award is re-measured each period until a commitment date is reached, which is generally the vesting date.

We also award restricted stock units to certain of our non-employee board members. At the time of vesting these awards are settled 65% in shares and 35% in cash. Awards settled in shares are accounted for based on the fair market value at the time of grant while awards settled in cash are accounted for based on the fair market value at the time of vesting.

Fair Value of Financial Instruments

The carrying amounts of our cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, approximate fair value because of their short maturities.

Cash Equivalents and Marketable Securities

Cash equivalents include all highly liquid investments maturing within 90 days from the date of purchase.

Marketable securities are classified as held-to-maturity as we have the intent and ability to hold these investments to maturity. Marketable securities are reported at amortized cost. Cash equivalents and marketable securities are invested in instruments we believe to be of high-quality, primarily money market funds, U.S. Government obligations, state and municipality obligations and corporate bonds with remaining contractual maturities of less than one year.

Accounts Receivable and Allowance for Doubtful Accounts

We review accounts receivable on a regular basis and estimate an amount of losses for uncollectible accounts based on our historical collections experience, age of the receivable and knowledge of the customer. We record changes in our estimate to the allowance for doubtful accounts through bad debt expense and relieve the allowance when accounts are ultimately collected or determined to be uncollectible.

Financing Costs Related to Initial Public Offering

Through December 31, 2012 and 2011, we had incurred $4,112 and $2,173, respectively, of legal and accounting costs related to our IPO. As of December 31, 2011 such costs were capitalized as prepaid expense and other current assets. Upon completion of our IPO on July 25, 2012, these amounts were offset against the proceeds received from the IPO and reclassified to equity.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment is computed on a straight-line basis over the estimated useful lives of the assets or, when applicable, the life of the lease, whichever is shorter.

Software and Website Development Costs

Certain costs to develop internal use computer software are capitalized provided these costs are expected to be recoverable. These costs are included in property and equipment and are amortized over three years beginning when the asset is substantially ready for use. Costs incurred during the preliminary project stage, as well as maintenance and training costs are expensed as incurred. We capitalized $1,095, $1,020 and 1,363 of software development costs and amortized $1,096, $881 and $621 in the years ended December 31, 2012, 2011, and 2010 respectively.

Impairment of Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. When such events occur, we compare the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there is impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. During the year ended December 31, 2011, we recorded an impairment charge of $15.0 million on trade and domain name assets related to our decision to discontinue the sidestep.com URL. See “—Note 6—Intangible Assets” for additional description of our impairment charge.

Goodwill

Goodwill represents the excess of the cost of an acquired business over the fair value of the assets acquired at the date of acquisition. Goodwill is tested for impairment at least annually and whenever events or changes in circumstances indicate that goodwill may be impaired. Goodwill is not deductible for tax purposes.

We assess goodwill for possible impairment using a two-step process. The first step identifies if there is potential goodwill impairment using either a quantitative or qualitative assessment. If step one indicates that an impairment may exist, a second step is performed to measure the amount of the goodwill impairment, if any. Goodwill impairment exists when the estimated fair value of goodwill is less than its carrying value. If impairment exists, the carrying value of the goodwill is reduced to fair value through an impairment charge in our consolidated statements of operations.

For purposes of goodwill impairment testing, we estimate the fair value of the Company using generally accepted valuation methodologies, including market and income based approaches, and relevant data available through and as of the testing date. The market approach is a valuation method in which fair value is estimated based on observed prices in actual transactions and on asking prices for similar assets. Under the market approach, the valuation process is essentially that of comparison and correlation between the subject asset and other similar assets. The income approach is a method in which fair value is estimated based on the cash flows that an asset could be expected to generate over its useful life, including residual value cash flows. These cash flows are then discounted to their present value using a rate of return that accounts for the relative risk of not realizing the estimated annual cash flows and for the time value of money.

Warrant liability

Warrants to purchase redeemable convertible preferred stock were accounted for on the balance sheets at fair value as liabilities. Changes in fair value are recognized in earnings in the period of change.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income consists of foreign currency translation adjustments. The financial statements of non-U.S. entities are translated from their functional currencies into U.S. dollars. Assets and liabilities are translated at period end rates of exchange and revenue and expenses are translated using average rates of exchange. The resulting gain or loss is included in accumulated other comprehensive income on the balance sheet.

Income Taxes

We record income taxes under the liability method. Interest and penalties related to income tax liabilities, if any, are included in income tax expense. Deferred tax assets and liabilities reflect our estimation of the future tax consequences of temporary differences between the carrying amounts of assets and liabilities for book and tax purposes. We determine deferred income taxes based on the differences in accounting methods and timing between financial statement and income tax reporting. Accordingly, we determine the deferred tax asset or liability for each temporary difference based on the enacted tax rates expected to be in effect when we realize the underlying items of income and expense. We consider many factors when assessing the likelihood of future realization of our deferred tax assets, including our recent earnings experience by jurisdiction, expectations of future taxable income, and the carryforward periods available to us for tax reporting purposes, as well as other relevant factors. We may establish a valuation allowance to reduce deferred tax assets to the amount we believe is more likely than not to be realized. Due to inherent complexities arising from the nature of our businesses, future changes in income tax law, tax sharing agreements or variances between our actual and anticipated operating results, we make certain judgments and estimates. Therefore, actual income taxes could materially vary from these estimates.

We follow authoritative guidance for uncertainty in income taxes, which requires that we recognize a tax benefit from an uncertain position only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. If this threshold is met, we measure the tax benefit as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Penalties and interest on uncertain tax positions are included in income tax expense.

We compute the reduction in taxes payable resulting from stock option exercises and other stock-based compensation by comparing our tax liabilities with and without stock-based tax deductions.

Recent Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board, or FASB, issued amended disclosure requirements for the presentation of comprehensive income. The amended guidance eliminates the option to present components of other comprehensive income (OCI) as part of the statement of changes in equity. Under the amended guidance, all changes in OCI are to be presented either in a single continuous statement of comprehensive income or in two separate but consecutive financial statements. We adopted these changes effective January 1, 2012 and applied retrospectively for all periods presented. There was no impact to the consolidated results as the amendments related only to changes in financial statement presentation.

In September 2011, the FASB issued amended guidance that will simplify how entities test goodwill for impairment. After an assessment of certain qualitative factors, if it is determined to be more likely than not that the fair value of a reporting unit is less than its carrying amount, entities must perform the quantitative analysis of the goodwill impairment test. Otherwise, the quantitative test becomes optional. The guidance is effective January 1, 2012, with early adoption permitted. We elected to adopt this guidance for the 2011 goodwill impairment test performed in the fourth quarter. Goodwill impairment testing did not result in any impact to our financial results.

3. Acquisitions

On May 6, 2010, the Company acquired 100% of the outstanding share capital in swoodoo AG, a leading German travel search company, for a total purchase price of $24,384, consisting of $6,781 in cash, net, and 825,000 shares of common stock valued at $13.00 per share on the date of the acquisition. Pursuant to an option agreed to with the former swoodoo stockholders, we were obligated, at a holder’s request given on or prior to August 12, 2011, to repurchase any or all of such shares owned by such holder at a price of €13.33 per share. We recorded a liability for the estimated fair value of this obligation at $4,208 at the time of acquisition. This amount was recorded as contingent consideration and is included in the purchase price above. The fair value of the obligation decreased by $1,262 and $2,946 for the years ended December 31, 2011 and 2010, respectively. During 2011, $1,126 of the decrease in the liability was recorded as a gain and is included in other income (expense), net. As of August 12, 2011, the expiration date of the option, these holders elected to sell back to the Company an aggregate of 685,219 of these shares. As a result of the exercises of this option, the Company acquired these shares for a cash payment of approximately $13,200.

We recognized $419 of acquisition-related expenses, for the year ended December 31, 2010 that were included in other general and administrative expenses.

The following table summarizes the consideration paid for swoodoo AG and the amounts of the assets acquired and liabilities assumed at the acquisition date.

Fair value of consideration transferred:






Cash paid	$	8,777
Cash paid for working capital adjustment	674
Fair value of common stock	10,725
Fair value of put options issued	4,208
Total purchase consideration	$	24,384

The table below sets forth the final purchase price allocation.





Assets acquired:

Total net assets acquired	$	24,384

(1) The weighted average useful life of the identifiable intangible assets acquired is 8 years.

The primary elements that generated goodwill are the value of the acquired assembled workforce, specialized processes and procedures and operating synergies, none of which qualify as separate intangible asset.

The pro forma impact of this acquisition on revenues and net income was immaterial.

On April 1, 2011, the Company acquired 100% of the outstanding share capital in JaBo Vertrieb-und Entwicklung GmbH, or JaBo Software, a leading Austrian travel search company, for a total cash purchase price of $9,160, net.

The table below sets forth the final purchase price allocation:





Assets acquired:
Accounts receivable and other assets	$	983
Contingent asset	230
Identifiable intangible assets (1)
Customer relationships (useful life—7 years)	3,200
Trade & domain names (useful life—10 years)	2,600
Current technology (useful life—2 years)	700

Depreciation expense was $2,706, $1,920 and $2,202 for the years ended December 31, 2012, 2011 and 2010, respectively.

6. Intangible Assets

The following tables detail our intangible asset balances by major asset class:



	December 31, 2012							December 31, 2011
	Gross Carrying Amount		Accumulated Amortization & Impairment			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Impairment			Net Carrying Amount
Intangible asset class
Domain and trade names	$	33,742	$	(27,143	)	$	6,599	$	33,505	$	(11,255	)	$	(14,980	)	$	7,270
Customer relationships	11,041		(5,422		)	5,619		10,878		(3,826		)	—			7,052
Technology	4,173		(4,092		)	81		4,160		(1,287		)	—			2,873
Non-compete agreements	1,002		(883		)	119		982		(493		)	—			489
Intangible assets, net	$	49,958	$	(37,540	)	$	12,418	$	49,525	$	(16,861	)	$	(14,980	)	$	17,684

Amortization expense was $5,567, $6,566 and $4,619 for the years ended December 31, 2012, 2011 and 2010, respectively. Intangible assets are amortized on a straight-line basis over their estimated economic lives. We believe that the

straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained.

In January 2011, we determined that we would not support two brand names and URLs in the United States and decided that we would begin to migrate all traffic from sidestep.com to KAYAK.com. As a result of this triggering event, we prepared

an analysis comparing expected future discounted cash flows to be generated by the SideStep domain and trade name asset to the carrying value of the asset. Our analysis resulted in:


•	A charge of $14,980 due to the impairment of the value of the SideStep brand name and URL,


•	A change in estimate that resulted in acceleration of amortization based on the estimated decline in queries directed from our SideStep URL through December 2013 to reflect the gradual transition of users to the KAYAK URL.

To determine fair value of the SideStep brand name and URL, we used an income approach, which utilized Level 3 fair value inputs as described in "- Note 15 - Fair Value Measurements", and discounted the expected cash flows of the intangible assets. We calculated expected cash flows, using an estimate of future revenue to be generated from the SideStep URL offset by estimated future expenses. We applied a discount rate of 17.0% representing the estimated weighted average cost of capital, which reflects the overall level of inherent risk involved in the respective operations and the rate of return an outside investor could expect to earn.

As of December 31, 2012, future amortization expense for the next 5 years and after is expected to be:





2013	$	2,099
2014	1,845
2015	1,845
2016	1,845
2017	1,823
Thereafter	2,961
Total	$	12,418

9. Income Taxes

Domestic pre-tax income was $45,371, $11,805, and $20,636 for the years ended December 31, 2012, 2011 and 2010, respectively. Foreign pre-tax income (loss) was $(7,030), $4,579 and $(484) for the years ended December 31, 2012, 2011 and 2010 respectively.

The significant components of the provision for income taxes are as follows:



	December 31,
	2012			2011			2010
Current:
Federal	$	19,299		$	12,665		$	3,648
State	4,349			3,864			3,576
Foreign	1,961			2,844			146
Total current	25,609			19,373			7,370

Foreign	(698		)	(1,743		)	(209		)
Total deferred	(6,078		)	(12,692		)	4,750
Income tax expense	$	19,531		$	6,681		$	12,120

Provisions for income taxes compared with income taxes based on the federal statutory tax rate of 35% were as follows:



	December 31,
	2012		2011		2010
U.S. Statutory federal income tax rate	35.0	%	35.0	%	35.0	%
State income taxes, net of federal benefits	5.3	%	7.2	%	8.3	%
Compensation related to incentive stock options	1.6	%	6.0	%	7.1	%
Gain on sale of TravelPost	—		—		4.4	%

Other	(1.1	)%	(2.1	)%	2.1	%
Effective income tax rate	50.9	%	40.8	%	60.1	%

Significant components of deferred tax assets and (liabilities) at December 31, 2012 and 2011 were as follows:



	December 31,
	2012			2011
Deferred tax assets:
Net operating loss carryforward	$	4,462		$	4,037
Accruals and reserves	1,693			1,633
Stock compensation	9,947			6,431
Tax credits	60			21
Total gross deferred tax assets	16,162			12,122
Valuation allowance	(1,189		)	(1,627		)
Total deferred tax assets	14,973			10,495
Deferred tax liabilities:
Depreciation and amortization	(3,944		)	(4,997		)
Net deferred tax asset	$	11,029		$	5,498

At December 31, 2012, we had approximately $5,369, $29,741 and $8,741 of federal, state and foreign tax operating loss carryforwards respectively. The federal, state and foreign operating loss carryforwards begin to expire in 2021, 2015 and 2020, respectively. This includes the effect of Section 382 limitations on our federal NOL due to certain ownership changes in prior years. We had approximately $464 of tax credits at December 31, 2010, which are not included in the above deferred tax schedule. The credits were fully utilized in 2011 and the tax benefit was recorded in additional paid in capital.

During the year ended December 31, 2010, we recorded a valuation allowance against our California net operating losses and credits, based on our decision to reduce our physical presence in California and local law in effect at that time. In 2012, California changed its law. A review of this legislation demonstrates these NOLs will in fact be utilized and we believe it more likely than not that the full value of the deferred tax asset will be realized and the valuation allowance was released in the fourth quarter of 2012. We have foreign NOLs that we do not believe are more likely than not to be realized and a full valuation allowance was recorded.

We have not recorded U.S. income and foreign withholding tax liabilities on the unremitted earnings of our foreign subsidiaries, because we intend to permanently reinvest those earnings. The amount of unremitted earnings at December 31, 2012, for which U.S. income and foreign withholding tax liabilities have not been provided, is approximately $500. At this time, determination of the amount of unrecognized tax liabilities is not practicable.

The following table summarizes the changes in the balance of gross unrecognized tax benefits for the years ended December 31, 2012 and 2011:



	December 31,
	2012			2011		2010
Gross unrecognized tax benefits as of beginning of the period	$	840		$	513	$	231
Increases based on tax positions related to the current year	1,691			—		—
Increases related to tax positions from prior fiscal years	2,690			327		282
Decreases due to statute expiration	(71		)	—		—
Settlements with tax authority	(319		)	—		—
Total gross unrecognized tax benefits as of end of period	$	4,831		$	840	$	513

All of the unrecognized tax benefits, if recognized, would impact our effective tax rate. The Company does not currently anticipate that the total amount of unrecognized tax benefits will significantly change within the next 12 months. We recognize interest and penalties related to uncertain tax positions tax benefits in income tax expense. As of December 31, 2012, 2011 and 2010, total gross interest and penalties accrued was $424, $101, and $0 respectively. In connection with our uncertain tax positions, we recognized interest expense in 2012, 2011 and 2010 of $323, $101, and $0, respectively.

All years are open for examination by federal, state and foreign taxing authorities. The Commonwealth of Massachusetts commenced an audit of our 2007 through 2010 income tax returns during the first quarter of 2011. We believe we have adequately reserved for all uncertain tax positions.

10. Commitments and Contingencies

Operating Leases

We lease our office and data center facilities under noncancelable leases that expire at various points between May 2013 and April 2025. We are also responsible for certain real estate taxes, utilities and maintenance costs on our office facilities. Rent expense was approximately $2,912, $1,746 and $1,070 for the years ended December 31, 2012, 2011, and 2010 respectively. Future minimum payments under non cancelable operating lease agreements as of December 31, 2012 are as follows:






2013	$	3,125
2014	2,766
2015	2,660
2016	2,379
2017	1,575
Thereafter	6,238
Total	$	18,743

Other Commitments

We have a content licensing agreement that as of December 31, 2012, obligates us to make future minimum payments of $5,612 in 2013. If this content licensing agreement is not renewed, it will expire in December 2013.

On April 3, 2012, we entered into a Products and Services Agreement with a technology provider. This agreement obligates us to make minimum future payments of $1,600 per year for the next three years.

We have two content delivery agreements that as of December 31, 2012, obligate us to make minimum future payments of $700 in 2013, $677 in 2014, and $56 in 2015.

We have up-front marketing agreements that as of December 31, 2012, obligate us to make minimum future payments of $17,932 for the first three quarters of 2013.

Legal Matters

We are involved in various legal proceedings, including but not limited to the matters described below that involve claims for substantial amounts of money or for other relief or that might necessitate changes to our business or operations.

In connection with our merger with priceline.com, we, along with our board, priceline.com, and Produce Merger Sub, a wholly-owned subsidiary of priceline.com were named as defendants in three complaints. Two claims were filed in the Delaware Court of Chancery and one claim was filed in the Judicial District of Stamford / Norwalk, Connecticut. All claims generally allege, among other things, that our board failed to adequately discharge its fiduciary duties to the holders of shares of our Class A common stock by failing to ensure they will receive maximum value for their shares, failing to conduct an appropriate sale process and agreeing to inappropriate provisions in the merger agreement that would dissuade or otherwise preclude the emergence of a superior offer. The claims also allege that we and priceline.com aided and abetted our board's breach of its fiduciary duties. The actions seek injunctive relief compelling the board to properly exercise its fiduciary duties to holders of shares of our Class A common stock, enjoining the consummation of the merger and declaring the merger agreement unlawful and unenforceable, among other things. All claims seek to recover costs and disbursements from the defendants, including reasonable attorneys' and experts fees. On January 16, 2013, the parties entered into a Memorandum of Understanding with the plaintiffs for each complaint described above to settle those lawsuits. The settlement is subject to executing a definitive stipulation of settlement and court approval following notice to our stockholders and consummation of the merger. If the settlement is approved, it will resolve and release all claims that were or could have been brought challenging

any aspect of the merger, the merger agreement and any disclosure made in connection therewith, among other claims. The settlement will not have a material impact on the Company's results of operations or cash flows.

In April 2009, Parallel Networks, LLC filed a complaint against us for patent infringement in the U.S. District Court for the Eastern District of Texas. The complaint alleged, among other things, that our website technology infringes a patent owned by Parallel Networks purporting to cover a “Method And Apparatus For Client-Server Communication Using a Limited Capability Client Over A Low-Speed Communications Link” (U.S. Patent No. 6,446,111 B1) and sought injunctive relief, monetary damages, costs and attorneys' fees. The complaint was dismissed without prejudice in February 2010, but the plaintiff filed a new complaint against us on March 29, 2010 containing similar allegations. On January 12, 2012, the Court entered final judgment against some defendants, not including KAYAK, and stayed the case against KAYAK pending resolution of any appeal. On January 16, 2013, the Federal Circuit affirmed the district court's grant of summary judgment, however, final judgment on the appeal has not yet issued and Parallel still has a right to request a rehearing or to file a petition with the Supreme Court. Upon conclusion of that petition or if Parallel decides not to pursue the appeal any further, we expect Parallel to move to lift the stay against KAYAK in early-to-mid 2013. The Court will then set a new trial date and enter a new scheduling order. At this time we are unable to estimate any potential damages associated with this matter.

In addition, from time to time, we may become involved in legal proceedings arising in the ordinary course of our business. Such proceedings, even if not meritorious, could result in the expenditure of significant financial and managerial resources. We have accrued for certain legal contingencies where it is probable that a loss has been incurred and the amount can be reasonably estimated.

11. Redeemable Convertible Preferred Stock

As of December 31, 2011, we had authorized 26,876,384 shares of redeemable convertible preferred stock, and had designated six series as follows : 6,600,000 shares of Series A Redeemable Convertible Preferred Stock, 1,176,051 shares of Series A-1 Redeemable Convertible Preferred Stock, 4,989,308 shares of Series B Redeemable Convertible Preferred Stock, 2,138,275 shares of Series B-1 Redeemable Convertible Preferred Stock, 3,897,084 shares of Series C Redeemable Convertible Preferred Stock and 8,075,666 shares of Series D Redeemable Convertible Preferred Stock.

Upon the completion of our IPO on July 25, 2012, all of the outstanding shares of redeemable convertible preferred stock automatically converted into shares of Class B common stock.

Series A Preferred

In March and June 2004, we issued an aggregate of 6,600,000 shares of Series A Redeemable Convertible Preferred Stock, or Series A Preferred Stock, at $1.00 per share for gross proceeds of $6,600.

Series A-1 Preferred

In November 2004, we issued an aggregate of 825,000 shares of Series A-1 Redeemable Convertible Preferred Stock, or Series A-1 Preferred Stock, at $2.00 per share for gross proceeds of $1,650. The purchase price of the shares was subject to adjustment based on any dilution occurring as a result of any subsequent stock offering that occurred prior to February 1, 2006 at a price per share lower than $2.00. Consequently, in March 2005, an additional 351,051 shares were issued to Series A-1 holders to adjust the stock purchase price to $1.403 per share, the per-share price of the Series B Redeemable Convertible Preferred Stock.

Series B Preferred

In February 2005, we issued an aggregate 4,989,308 shares of Series B Redeemable Convertible Preferred Stock, or Series B Preferred Stock, at $1.403 per share for gross proceeds of $7,000.

Series B-1 Preferred

In April 2006, we issued an aggregate 2,138,275 shares of Series B-1 Redeemable Convertible Preferred Stock, or Series B-1 Preferred Stock, at $1.403 per share for gross proceeds of $3,000.

Series C Preferred

In May 2006, we issued an aggregate 3,855,180 shares of Series C Redeemable Convertible Preferred Stock, or Series C Preferred Stock, at $2.983 per share for gross proceeds of $11,500.

Series D Preferred

In December 2007, we issued an aggregate 8,008,842 shares of Series D Redeemable Convertible Preferred Stock, or Series D Preferred Stock, at $20.727 per share for gross proceeds of $166,000 and $278 in issuance costs.

A summary of the rights and preferences of the Series A, A-1, B, B-1, C and D Preferred Stock, as of December 31, 2012, are as follows:

Voting

Prior to our IPO, Series A, A-1, B, B-1, C and D Preferred stockholders are entitled to one vote per common share equivalent on all matters voted on by holders of common stock.

Dividends

Prior to our IPO, Series A, A-1, B, B-1, C and D Preferred stockholders were entitled to receive dividends that are paid on common stock of the Company equal to an amount of the largest number of whole shares of common stock into which the shares of preferred stock are convertible. In addition, holders of Series A, A-1, B, B-1, C and D Preferred Stock were entitled to receive, out of funds legally available, dividends at the rate of 6% per annum of the adjusted original issue price per share and are accumulated regardless if declared. Accumulated and unpaid dividends totaled $58,390 and $51,745 as of the date of the IPO, and December 31, 2011 respectively. Dividends were deemed payable upon a liquidation event, redemption or if declared by the Board of Directors. Upon the completion of our IPO, all accumulated dividends were reversed.

In April 2012, the Company executed an Election and Amendment Agreement with certain existing stockholders, or eligible holders, pursuant to which we granted certain eligible holders the right to purchase from us 352,178 shares of common stock at the IPO price of $26.00. We refer to these as the private placement purchase rights. The holders of these private placement purchase rights exercised 231,695 shares on August 1, 2012. These private placement purchase rights expired on August 1, 2012.

Pursuant to the Election and Amendment Agreement, since our IPO price was below $27.00 per share, we issued to the eligible holders additional shares of Class A common stock for no additional consideration pursuant to an automatic adjustment. As a result of the revision in the terms due to the Election and Amendment Agreement, we recognized a charge of $2,929 as a deemed dividend at the modification date. This charge impacted net income attributable to our common stockholders and basic net income per share attributable to common stockholders.

As a result of the completion of our IPO on July 25, 2012 all shares of outstanding redeemable convertible preferred stock converted into shares of Class B common stock.

Preferred Stock Warrants

In connection with the issuance of subordinated term loans in 2007, the lender received warrants to purchase 62,000 shares of Series D Preferred Stock at an exercise price of $20.73 per share. The warrants expire on the tenth anniversary of the loan closing date (December 2017). In connection with the transaction we recorded a separate warrant liability based on the estimated fair value at the issuance date by allocating proceeds first to the warrants and the remaining to the loans (the residual method). On July 20, 2012, the lender exercised this warrant on a cashless basis, based on a fair market value at the time of exercise of $33.18 per share. As a result, we issued to the lender an aggregate 23,269 shares of our Series D Preferred Stock. These shares automatically converted to Class B common stock upon the closing of our IPO. Warrants are valued at each reporting period with changes recorded as other income (expense) in the statement of operations. The fair value of these warrants was $0 and $426 at December 31, 2012 and 2011 respectively, based on the following assumptions using the Black-Scholes model:



	December 31, 2012	December 31, 2011
Risk free interest rate	—	0.4	%
Expected volatility	—	42.9	%
Expected life (in years)	—	3
Dividend yield	—	—	%

The mark-to-market gain (loss) on these warrants was $(346), $183, and $71 for the years ended December 31, 2012, 2011, and 2010 respectively.

In November 2006, under the terms of a loan and security agreement, we issued warrants for the purchase of 41,904 shares of Series C Preferred Stock. The warrants are exercisable at $2.983 per share and expire on November 22, 2016. On July 20, 2012, one of these lenders exercised on a cashless basis its warrant for 25,142, based on a fair market value at the time of exercise of $33.18 per share. As a result, we issued to the lender an aggregate 22,881 shares of our Series C Preferred Stock. These shares automatically converted to Class B common stock upon the closing of our IPO. Additionally, upon the closing of our IPO, the unexercised warrants automatically converted into warrants to purchase shares of our Class B common stock. In November, 2012 the remaining lender exercised on a cashless basis its warrant for 16,762, based on a fair market value of $34.68 per share. As a result, we issued to the lender an aggregate 15,320 shares of Class B common stock.

The fair value of these warrants was $0, and $724 as of December 31, 2012, and 2011 respectively, based on the following assumptions using the Black-Scholes model:



	December 31, 2012	December 31, 2011
Risk free interest rate	—	0.3	%
Expected volatility	—	41.0	%
Expected life (in years)	—	2
Dividend yield	—	—	%

The mark-to-market loss on these warrants was $(567), $(98) and $(226) for the years ended December 31, 2012, 2011 and 2010.

12. Stockholders’ Equity

Common Stock

A summary of the rights and preferences of our Class A and Class B common stock as of December 31, 2012 are as follows:

Voting

Holders of our Class A common stock are entitled to one vote per share and holders of our Class B common stock are entitled to 10 votes per share on all matters on which such common stockholders are entitled to vote.

Dividends

Holders of our Class A and Class B common stock are eligible to receive dividends on common stock held when funds are available and as approved by the board of directors.

Liquidation Rights

In the event of liquidation, dissolution or winding up of the Company, a sale of all or substantially all of the Company’s assets, and certain mergers, common stockholders are entitled to receive all assets of the Company available for distribution, subject to the preferential rights of any outstanding shares of preferred stock.

13. Stock Options and Restricted Stock

The board of directors adopted the 2004 Stock Option Plan, or the 2004 Plan, the Third Amended and Restated 2005 Equity Incentive Plan, as amended, or the 2005 Plan, and the 2012 Equity Incentive Plan, or the 2012 Plan, which permits the issuance of equity awards including incentive and nonqualified stock options, restricted stock and restricted stock units to employees, directors and consultants. At December 31, 2012 and 2011, 616,279 shares and no shares, respectively, were available for issuance under our 2012 Plan. At December 31, 2012 and 2011, no shares and 159,946 shares, respectively, were available for issuance under our 2004 Plan and 2005 Plan.

Restricted Stock

The Company has issued shares of restricted common stock to employees, directors and consultants. There were no unvested shares of restricted stock outstanding at December 31, 2012 and 2011, respectively.

Restricted stock is subject to transfer restrictions and contains the same rights and privileges as unrestricted shares of common stock. Shares of restricted stock are presented as outstanding as of the date of issuance.

The following table summarizes the activity for our restricted stock:



	Number of Shares		Weighted- Average Grant Date Fair Value
Unvested at December 31, 2009	345		$	1.40
Granted	54,986		11.29
Vested	(55,331	)	11.23
Unvested at December 31, 2010	—		—
Granted	14,905		17.60
Vested	(14,905	)	17.60
Unvested at December 31, 2011	—		$	—

There were no restricted stock grants between January 1, 2012 and December 31, 2012.

Restricted Stock Units

On August 31, 2012, we issued an aggregate 33,655 restricted stock units to certain of our non-employee directors. These restricted stock units vest quarterly over a two-year period and are settled 65% in shares and 35% in cash. At the time of grant, the recipients of these awards were automatically vested with respect to an aggregate 11,779 of these shares.

On December 22, 2012, we issued an additional 4,373 restricted stock units to a non-employee director. The restricted stock units vest quarterly over a two-year period and are settled 65% in shares and 35% in cash.

Restricted stock units settled in cash are accounted for as liability awards and paid based on the fair market value of KAYAK stock on the date of vest. Restricted stock units settled in shares are accounted for as equity awards and expensed based on the fair market value on the date of grant.

The following table summarizes the activities for the unvested stock portion of our restricted stock unit grants for the year ended December 31, 2012:



	Shares Settled in Cash	Shares Settled in Shares	Weighted- Average Grant Date Fair Value
Unvested at December 31, 2011	—	—	$	—
Granted	13,310	24,718	28.75
Vested	7,065	13,128	27.29
Forfeited/canceled	—	—	—
Unvested at December 31, 2012	6,245	11,590	$	30.41
Expected to vest after December 31, 2012 (1)	5,303	9,855	$	30.42

(1) Restricted stock units expected to vest reflect an estimated forfeiture rate.

The unrecognized compensation cost related to unvested restricted stock units to be settled in shares and to be settled in cash was $264 and $179 respectively as of December 31, 2012. These amounts are expected to be recognized over a weighted-average period of 0.7 years as of December 31, 2012. To the extent the actual forfeiture rate is different from what we have estimated, stock-based compensation related to these awards will be different from our expectations.

Stock Options

Stock options generally have terms of ten years. Stock options granted under the stock plans will typically vest 25% after the first year of service and ratably each month over the remaining 36-month period contingent upon employment with the Company on the date of vesting.

We utilize the Black-Scholes model to determine the fair value of stock options. Management is required to make certain assumptions with respect to selected model inputs, including anticipated changes in the underlying stock price (i.e., expected volatility) and option exercise activity (i.e., expected term). We base our expected volatility on the historical volatility of comparable publicly traded companies for a period that is equal to the expected term of the options. The expected term of options granted is derived using the “simplified” method as allowed under the provisions of the SEC’s Staff Accounting Bulletin No. 107 and represents the period of time that options granted are expected to be outstanding. The expected term for performance-based and non-employee awards is based on the period of time for which each award is expected to be outstanding, which is typically the remaining contractual term. The risk-free rate is based on the U.S. Treasury yield in effect at the time of the grant period for a period commensurate with the estimated expected life.

The following table summarizes stock option activity:



	Number of Shares		Weighted-Average Exercise Price		Aggregate Intrinsic Value⁽¹⁾		Weighted-Average Remaining Contractual Term (in years)
Balance, December 31, 2011	9,086,586		$	10.79	$	86,590	7.3

(1)	The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying award and the fair value of $39.72, and $20.14 of our common stock on December 31, 2012, and 2011.


(2)	Includes 254,500 shares granted to non-employees. The assumptions used to value these grants are similar to those used for grants made to employees with the exception of the expected term.


(3)	Stock options expected to vest reflect an estimated forfeiture rate.

The fair value of vested shares was $10,841, $10,885 and $5,770 during the years ended December 31, 2012, 2011 and 2010. The total intrinsic value of options exercised was $4,963 and $4,143 during the years ended December 31, 2012 and 2011.

The weighted-average fair value of options granted during the years ended December 31, 2012 and 2011 was $13.34 per share and $9.71 per share respectively, based on the Black-Scholes model. The following weighted-average assumptions were used for grants made to employees and do not include the assumptions for non-employee grants:



	December 31, 2012		December 31, 2011
Risk-free interest rate	0.9	%	1.8	%

$ 1.00 - $40.70	10,678,836	6.9	$	13.89	6,347,735	$	8.69

Prior to the completion of our IPO, the fair value of the common stock was determined by the board of directors at each award grant date based on a variety of factors, including arm’s length sales of our capital stock (including redeemable convertible preferred stock), valuations of comparable public companies, our financial position and historical financial performance, the status of technological developments within our products, the composition and ability of the technology and management team, an evaluation of and benchmark to our competition, the current climate in the marketplace, the illiquid nature of the common stock, the effect of rights and preferences of preferred stockholders, and the prospects of a liquidity event, among others. Subsequent to the completion of our IPO, we utilize the closing price of our common stock on the date of grant to determine its fair value.

At December 31, 2012 and 2011, total unrecognized estimated compensation expense related to non-vested stock options granted prior to that date was approximately $43,295, and $38,250 respectively. This expense will be recognized on a straight-line basis over the weighted average remaining vesting period of 2.9 and 2.6 years as of December 31, 2012 and 2011 respectively.

14. Earnings per share

The following tables set forth the computation of basic and diluted earnings (loss) per share of common stock for the years ended December 31, 2012, 2011, and 2010 were as follows:

15. Fair Value Measurements

GAAP sets forth a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The three tiers are Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Our restricted stock units settled in cash are measured and recorded at fair value at the time of vesting. See “--Note 13-Stock Options and Restricted Stock” for further discussion of our restricted stock units.

Our preferred stock warrants are measured at fair value on a recurring basis. The preferred stock warrants are valued using the Black-Scholes model with the following assumptions: share price, exercise price, expected term, volatility, risk-free interest rate and dividend yield as described in “—Note 11—Redeemable Convertible Preferred Stock”.

Using the Black-Scholes model, the common stock put options were valued at $1,262 based on the following assumptions at December 31, 2010. As of December 31, 2012 and 2011 there were no outstanding put options. See “- Note 3 -Acquisitions” for further discussion of our swoodoo acquisition and the exercise of the put options.





	December 31, 2010
	December 31, 2010

Risk free interest rate	0.2	%
Expected volatility	31.0	%
Expected life (in years)	0.5
Dividend yield	—	%

Using the Black-Scholes model, the common stock options issued to non-employees were valued at $1,012 based on the following weighted-average assumptions at December 31, 2012 and a fair market value of $39.72. As of December 31, 2012 there were 254,500 outstanding common stock options outstanding. See “- Note 13 - Stock Options and Restricted Stock” for further discussion of our stock option plans and activity.

Changes in valuation during the years ended December 31, 2012, 2011 and 2010, were as follows:



	Level 3 Stock Put Options			Level 3 Warrant Instruments			Level 2 Non-Employee Common Stock Options
Balance, December 31, 2009	$	—		$	1,081
Fair value at issuance	4,208			—

Mark-to-market adjustments related to warrant instruments are included in other income (expense). Mark-to-market adjustments related to common stock options granted to non-employees are included in other general and administrative expenses.

16. Employee Benefit Plan

In June 2004, the Company established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis, subject to legal limitations. Company contributions to the plan may be made at the discretion of the Board of Directors. In March 2011, the Company implemented a program that matched a portion of employee 401(k) contributions. For the years ended December 31, 2012 and 2011, the company contributed $1,247 and $399 to the plan, respectively.

17. Related Party Transactions

In March 2010, we sold TravelPost, a website that was acquired in 2007, to a corporation affiliated with certain members of our board of directors. In return, we received 800,000 shares of common stock in the new company and $3,600 in cash. We recorded a gain on the sale of $459 which is included in other income (expense), net. In addition we entered into a commercial agreement pursuant to which we granted the new company a three-year license to reproduce and publicly display hotel reviews and hotel related information in exchange for a monthly license fee of $50 for the term of the license. In May 2011, the commercial agreement was amended to lower the monthly license fee to $10 in exchange for 1,000,000 shares of Series A Preferred Stock in TravelPost. No value was attributed to the stock.

18. Information about Geographic Areas

Revenues by geography are based on the country in which our websites are located. For example, KAYAK.com is in the United States, while KAYAK.de.com and swoodoo.com are in Germany. We allocate revenues based on the website’s proportional revenue-generating activity (generally, volume of queries and clicks relative to the whole). Long-lived assets are allocated based on the location of the corporate entity to which they relate.

1. Organization

KAYAK Software Corporation was incorporated in Delaware on January 14, 2004 under the name of Travel Search Company, Inc. On August 17, 2004, we officially changed our name to KAYAK Software Corporation, or KAYAK. We operate KAYAK.com and other travel websites and mobile applications that allow people to search for rates and availability for airline tickets, hotel rooms, rental cars, and other travel-related services across hundreds of websites and provide choices on where to book. As used in this report, the terms “we,” “us,” “our,” “KAYAK” and the “Company” mean KAYAK Software Corporation and its subsidiaries, unless the context indicates another meaning.

On November 8, 2012, we entered into an Agreement and Plan of Merger, or Merger Agreement, to be acquired by priceline.com Incorporated (NASDAQ: PCLN), or priceline.com. Under the terms of the Merger Agreement, KAYAK will merge with and into a wholly owned subsidiary of priceline.com.

At the effective time of the merger, each share of KAYAK Class A and Class B common stock issued and outstanding immediately prior to the effective time will, at the election of the holder and subject to proration as set forth in the Merger Agreement, be converted into the right to receive either (i) $40.00 per share of KAYAK Class A and Class B common stock or (ii) a fraction of a share of priceline.com common stock. The number of shares of priceline.com common stock issued in consideration for the Class A and Class B common stock will be based upon a formula as set forth in the Merger Agreement.

The merger was unanimously approved by the respective Boards of Directors of KAYAK and priceline.com and the Board of Directors of KAYAK recommended that KAYAK’s stockholders approve the proposed transaction.

On March 4, 2013, KAYAK stockholders voted to approve the adoption of the Merger Agreement. Approximately 96% of the total voting power of KAYAK's outstanding shares of Class A common stock and Class B common stock as of January 24, 2012, the record date for the special meeting of stockholders, were voted in favor of the adoption of the Merger Agreement.

On May 9, 2013, the UK Office of Fair Trading announced that it had cleared the merger of KAYAK with priceline.com. The closing date of the proposed merger has been scheduled for May 21, 2013 subject to the remaining conditions to closing being satisfied.

The Merger Agreement contains certain termination rights for both KAYAK and priceline.com and further provides that, upon termination of the Merger Agreement under certain circumstances, KAYAK may be obligated to pay priceline.com a termination fee of $52,700.

2. Summary of Significant Accounting Policies

Significant Estimates and Judgments

The preparation of financial statements in conformity with Generally Accepted Accounting Principles, or GAAP, in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these financial statements include the provision for uncollectible accounts, estimates used to determine the fair value of our common stock, preferred stock, stock-based compensation and preferred stock warrants, recoverability of our net deferred tax assets and the fair value of long lived assets and goodwill. Changes in estimates are recorded in the period in which they become known. We base

estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. Operating results of acquired businesses are included in the consolidated statements of operations from the date of acquisition. All intercompany accounts and transactions have been eliminated. We have reclassified certain prior period amounts to conform to our current period presentation.

The interim financial statements and footnotes are unaudited. In the opinion of our management, these statements include all adjustments, which are of a normal recurring nature, necessary to present a fair statement of the Company’s results of operations, financial position and cash flows. Interim results are not necessarily indicative of financial results for a full year. The interim information included in this Form 10-Q should be read in conjunction with the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2012.

Foreign Currency Translation

Segments

We have one operating segment for financial reporting purposes: travel search.

Revenue Recognition

We recognize distribution revenues upon completion of the referral. Provided that our fees are fixed and determinable, there is persuasive evidence of an arrangement and collection is reasonably assured. Advertising revenues are recognized when a traveler clicks on an advertisement that a customer has placed on our website or mobile application or when we display an advertisement.

Distribution Revenues

Advertising Revenues

Advertising revenues primarily come from payments for compare units, text-based sponsored links and display advertisements. A “compare unit” is an advertising placement that, if selected by a KAYAK user, launches the advertiser’s website and initiates a query based on the same travel parameters provided on the KAYAK website. The major types of advertisers on our websites consist of OTAs, third party sponsored link providers, hotels, airlines and vacation package providers. Generally, our advertisers pay us on a CPC basis, which means advertisers pay us only when someone clicks on one of their advertisements, or on a cost per thousand impression basis, or CPM. Paying on a CPM basis means that advertisers pay us based on the number of times their advertisements appear on our websites or mobile applications.

Concentrations of Credit Risk

Three significant customers accounted for the following percentages of total revenues:



	Three Months Ended March 31,
	2013	2012
Customer A	21%	22%
Customer B	14%	10%
Customer C	7%	11%

Amounts due from these significant customers were:



	March 31,		December 31,
	2013		2012
Customer A	$	9,203	$	5,485
Customer B	7,545		3,152
Customer C	5,310		3,813

We believe significant customer amounts outstanding at March 31, 2013 and December 31, 2012 are collectible.

Cost of Revenues

Cost of revenues consists primarily of expenses incurred related to airfare query costs, data center costs and related bandwidth charges. All costs of revenues are expensed as incurred.

Marketing

Stock-Based Compensation

We account for stock options issued to non-employees in accordance with the guidance for equity-based payments to non-employees. Stock option awards to non-employees are accounted for at fair value using the Black-Scholes option-pricing model. Our management believes that the fair value of stock options is more reliably measured than the fair value of the services received. The fair value of the unvested portion of the options granted to non-employees is re-measured each period. The resulting increase or decrease in value, if any, is recognized during the period the related services are rendered. The fair value of each non-employee stock-based compensation award is re-measured each period until a commitment date is reached, which is generally the vesting date.

Fair Value of Financial Instruments

The carrying amounts of our cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, approximate fair value because of their short maturities.

Cash Equivalents and Marketable Securities

Cash equivalents include all highly liquid investments maturing within 90 days from the date of purchase.

Accounts Receivable and Allowance for Doubtful Accounts

Property and Equipment

Software and Website Development Costs

Certain costs to develop internal use computer software are capitalized provided these costs are expected to be recoverable. These costs are included in property and equipment and are amortized over three years beginning when the asset is substantially ready for use. Costs incurred during the preliminary project stage, as well as maintenance and training costs were expensed as incurred. We capitalized $101 and $222 of software development costs and amortized $280 and $260 in the three months ended March 31, 2013 and March 31, 2012, respectively.

Impairment of Long-Lived Assets

Goodwill

Goodwill represents the excess of the cost of acquired business over the fair value of the assets acquired at the date of acquisition. Goodwill is tested for impairment at least annually and whenever events or changes in circumstances indicate that goodwill may be impaired. Goodwill is not deductible for tax purposes.

We assess goodwill for possible impairment using a two-step process. The first step identifies if there is potential goodwill impairment. If step one indicates that an impairment may exist, a second step is performed to measure the amount of the goodwill impairment, if any. Goodwill impairment exists when the estimated fair value of goodwill is less than its carrying value. If impairment exists, the carrying value of the goodwill is reduced to fair value through an impairment charge in our consolidated statements of operations.

Accumulated Other Comprehensive Income

Income Taxes

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board issued accounting guidance which requires entities to provide additional information about items reclassified out of accumulated other comprehensive income ("AOCI"). Changes in AOCI balances by component, both before tax and after tax, must be disclosed and significant items reclassified out of AOCI by component must be reported either on the face of the income statement or in a separate footnote to the financial statements. The accounting guidance is effective for public companies for fiscal years, and interim periods within those years, beginning after December 15, 2013. There were no reclassifications out of AOCI for the three months ended March 31, 2013 and 2012.

3. Marketable Securities

The following tables summarize the investments in marketable securities all of which are classified as held to maturity:



	March 31, 2013				December 31, 2012
	Amortized Cost		Level 1(1) Fair Value		Amortized Cost		Level 1(1) Fair Value
Commercial paper	—		—		900		900
Corporate debentures/bonds	1,985		1,984		5,712		5,712
Marketable securities	$	1,985	$	1,984	$	6,612	$	6,612


(1)	Level 1 fair values are defined as observable inputs such as quoted prices in active markets.

4. Property and Equipment

Property and equipment consisted of the following:



	Estimated Life	March 31,			December 31,
		2013			2012
Website development	3 years	$	3,374		$	6,647
Computer equipment	3 years	4,999			5,340
Leasehold improvements	Life of lease	2,487			2,470
Furniture and fixtures	5 years	1,055			1,084
Software	3 years	608			318
Vehicles	5 years	109			109
Office equipment	5 years	35			46
Construction in progress	N/A	167			1,240
Property and equipment		12,834			17,254
Accumulated depreciation		(6,147		)	(10,351		)
Property and equipment, net		$	6,687		$	6,903

Depreciation expense was $937 and $635 for the three months ended March 31, 2013 and 2012, respectively.

5. Intangible Assets

The following tables detail our intangible asset balances by major asset class:



	March 31, 2013							December 31, 2012
	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Intangible asset class
Domain and trade names	$	33,496	$	(27,297	)	$	6,199	$	33,742	$	(27,143	)	$	6,599
Customer relationships	10,799		(5,606		)	5,193		11,041		(5,422		)	5,619
Technology	4,153		(4,153		)	—		4,173		(4,092		)	81
Non-compete agreements	972		(949		)	23		1,002		(883		)	119
Intangible assets, net	$	49,420	$	(38,005	)	$	11,415	$	49,958	$	(37,540	)	$	12,418

Amortization expense was $655 and $1,415 for the three months ended March 31, 2013, and March 31, 2012, respectively. Intangible assets are amortized on a straight-line basis over their estimated economic lives. We believe that the straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained.

6. Goodwill

Changes in the carrying amount of goodwill for the year ended December 31, 2012 and three months ended March 31, 2013 were as follows:





Balance, December 31, 2012	$	155,988
Foreign currency translation	(461		)
Balance, March 31, 2013	$	155,527

7. Accrued Expenses and Other Current Liabilities

Accrued expenses and other current liabilities consisted of the following:



	March 31, 2013		December 31, 2012
Accrued marketing	$	11,480	$	7,527
Accrued search fees	2,254		1,529
Accrued bonus	2,059		1,080
Accrued vacation	1,555		1,264
Accrued professional fees	1,175		1,651
Income taxes payable	579		6,346
Other accrued expenses	4,822		4,744
Accrued expenses and other current liabilities	$	23,924	$	24,141

8. Income Taxes

Our effective tax rates were 64.9% and 47.8% for the three months ended March 31, 2013 and 2012, respectively. The effective tax rate for the three months ended March 31, 2013 was higher than the statutory rate due to state taxes and losses in Europe for which no benefit was recognized, partially offset by federal and state research credits. The effective tax rate for the three months ended March 31, 2012 was higher than the statutory rate primarily due to state taxes, losses in Europe for which no benefit was recognized and disallowed stock compensation expense for incentive stock options.

9. Commitments and Contingencies

Operating Leases

We lease our office and data center facilities under noncancelable leases that expire at various points between May 2013 and April 2025. We are also responsible for certain real estate taxes, utilities and maintenance costs on our office facilities. Rent expense was approximately $898 and $535 for the three months ended March 31, 2013 and 2012, respectively.

Other Commitments

We have up-front marketing agreements that as of March 31, 2013, obligate us to make minimum future payments of $10,997 for the remainder of 2013.

We have a content licensing agreement that as of March 31, 2013, obligates us to make minimum future payments of $4,335 for the remainder of 2013. If not renewed, this agreement expires in December 2013.

We have two content delivery agreements that as of March 31, 2013, obligate us to make minimum future payments of $531 for the remainder of 2013, $677 in 2014, and $56 in 2015.

Legal Matters

appropriate sale process and agreeing to inappropriate provisions in the merger agreement that would dissuade or otherwise preclude the emergence of a superior offer. The claims also allege that we and priceline.com aided and abetted our board's

breach of its fiduciary duties. The actions seek injunctive relief compelling the board to properly exercise its fiduciary duties to holders of shares of our Class A common stock, enjoining the consummation of the merger and declaring the merger agreement unlawful and unenforceable, among other things. All claims seek to recover costs and disbursements from the defendants, including reasonable attorneys' and experts fees. On January 16, 2013, the parties entered into a Memorandum of Understanding with the plaintiffs for each complaint described above to settle those lawsuits. The settlement is subject to executing a definitive stipulation of settlement and court approval following notice to our stockholders and consummation of the merger. If the settlement is approved, it will resolve and release all claims that were or could have been brought challenging any aspect of the merger, the merger agreement and any disclosure made in connection therewith, among other claims. The settlement will not have a material impact on the Company's consolidated results of operations or cash flows.

10. Redeemable Convertible Preferred Stock

As of December 31, 2011, we had authorized 26,876,384 shares of redeemable convertible preferred stock, and had designated six series as follows: 6,600,000 shares of Series A Redeemable Convertible Preferred Stock, 1,176,051 shares of Series A-1 Redeemable Convertible Preferred Stock, 4,989,308 shares of Series B Redeemable Convertible Preferred Stock, 2,138,275 shares of Series B-1 Redeemable Convertible Preferred Stock, 3,897,084 shares of Series C Redeemable Convertible Preferred Stock and 8,075,666 shares of Series D Redeemable Convertible Preferred Stock.

Upon the completion of our IPO on July 25, 2012, all of the outstanding shares of redeemable convertible preferred stock automatically converted into shares of Class B common stock.

Dividends

Pursuant to the Election and Amendment Agreement, since our IPO price was below $27.00 per share, we issued to the eligible holders additional shares of Class A common stock for no additional consideration pursuant to an automatic adjustment. As a result of the revision in the terms due to the Election and Amendment Agreement, we recognized a charge of $2,929 as a deemed dividend at the modification date. This charge impacted 2012 annual net income (loss) attributable to our common stockholders and basic net income (loss) per share attributable to common stockholders.

11. Stockholders’ Equity

Common Stock

A summary of the rights and preferences of our Class A and Class B common stock as of March 31, 2013 are as follows:

Voting

Dividends

Holders of our Class A and Class B common stock are eligible to receive dividends on common stock held when funds are available and as approved by the board of directors.

Liquidation Rights

12. Stock Options and Restricted Stock

The board of directors adopted the 2004 Stock Option Plan, or the 2004 Plan, the Third Amended and Restated 2005 Equity Incentive Plan, as amended or the 2005 Plan, and the 2012 Equity Incentive Plan, or the 2012 Plan, which permits the issuance of equity awards including incentive and nonqualified stock options, restricted stock and restricted stock units to employees, directors and consultants. At March 31, 2013 and December 31, 2012, 2,296,953 shares and 616,279 shares, respectively, were available for issuance under our 2012 Plan. At March 31, 2013 and December 31, 2012, no shares were available for issuance under our 2004 Plan and 2005 Plan.

Restricted Stock Units

The following table summarizes the activities for the unvested stock portion of our restricted stock unit grants for the quarter ended March 31, 2013:



	Shares Settled in Cash	Shares Settled in Shares	Weighted- Average Grant Date Fair Value
Balance, unvested at December 31, 2012	6,245	11,590	$	30.41
Granted	—	—	—
Vested	1,665	3,091	28.76
Forfeited/canceled	—	—	—
Balance, unvested at March 31, 2013	4,580	8,499	$	31.01
Expected to vest after March 31, 2013 (1)	4,341	8,081	$	31.02

(1) Restricted stock units expected to vest reflect an estimated forfeiture rate.

The unrecognized compensation cost related to unvested restricted stock units to be settled in shares and to be settled in cash was $152 and $101 respectively as of March 31, 2013. These amounts are expected to be recognized over a weighted-

average period of 0.7 years as of March 31, 2013. To the extent the actual forfeiture rate is different from what we have estimated, stock-based compensation related to these awards will be different from our expectations.

Stock Options

We may award certain employees and non-employees options to acquire shares of our Class B common stock. Stock options generally have terms of ten years. Stock options granted under the stock plans will typically vest 25% after the first year of service and ratably each month over the remaining 36-month period contingent upon employment with the Company on the date of vesting.

We utilize the Black-Scholes model to determine the fair value of stock options. Management is required to make certain assumptions with respect to selected model inputs, including anticipated changes in the underlying stock price (e.g., expected volatility) and option exercise activity (e.g., expected term). We base our expected volatility on the historical volatility of comparable publicly traded companies for a period that is equal to the expected term of the options. The expected term of options granted is derived using the “simplified” method as allowed under the provisions of the Securities and Exchange Commission, or SEC’s, Staff Accounting Bulletin No. 107 and represents the period of time that options granted are expected to be outstanding. The expected term for performance-based and non-employee awards is based on the period of time for which each award is expected to be outstanding, which is typically the remaining contractual term. The risk-free rate is based on the U.S. Treasury yield in effect at the time of the grant period for a period commensurate with the estimated expected life.

The following table summarizes stock option activity:



	Number of Shares		Weighted-Average Exercise Price		Aggregate Intrinsic Value(1)		Weighted-Average Remaining Contractual Term (in years)
Balance, December 31, 2012	10,678,836		$	13.89	$	275,899	6.9

(1)	The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying award and the fair value of $39.96, and $39.72 of our Class A common stock on March 31, 2013 and December 31, 2012, respectively.


(2)	Includes 254,500 shares granted to non-employees which are marked-to-market until they are fully vested. The assumptions used to value these grants are similar to those used for grants made to employees with the exception of the expected term.


(3)	Stock options expected to vest reflect an estimated forfeiture rate.

The fair value of vested shares was $3,640 at March 31, 2013 and $3,075 at March 31, 2012. The total intrinsic value of options exercised was $11,103 for the three months ended March 31, 2013 and $4,963 during the year ended December 31, 2012.

The weighted-average fair value of options granted during the three months ended March 31, 2013 was $18.23 per share and $13.34 per share for the year ended December 31, 2012 based on the Black-Scholes model. The following weighted-average assumptions were used for grants made to employees and do not include the assumptions for non-employee grants:



	March 31, 2013		December 31, 2012
Risk-free interest rate	1.0	%	0.9	%
Expected volatility	45.9	%	44.9	%

Prior to the completion of our IPO, the fair value of the common stock was determined by the board of directors at each award grant date based on a variety of factors, including arm’s length sales of our capital stock (including redeemable convertible preferred stock), valuations of comparable public companies, our financial position and historical financial performance, the status of technological developments within our products, the composition and ability of the technology and management team, an evaluation of and benchmark to our competition, the current climate in the marketplace, the illiquid nature of the common stock, the effect of rights and preferences of preferred shareholders, and the prospects of a liquidity event, among others. Subsequent to the completion of our IPO, we utilize the closing price of our common stock on the date of grant to determine its fair value.

At March 31, 2013 and December 31, 2012, total unrecognized estimated compensation expense related to non-vested stock options granted prior to that date was approximately $38,373 and $43,295, respectively. This expense will be recognized on a straight-line basis over the weighted average remaining vesting period of 2.5 and 2.9 years as of March 31, 2013, and December 31, 2012, respectively.
