Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Competition Reviews The online travel industry has become the subject of investigations by various national competition authorities ("NCAs"), particularly in Europe. The Company is or has been involved in investigations predominantly related to whether Booking.com's contractual parity arrangements with accommodation providers, sometimes also referred to as "most favored nation" or "MFN" provisions, are anti-competitive because they require accommodation providers to provide Booking.com with room rates that are at least as low as those offered to other online travel companies ("OTCs") or through the accommodation provider's website. Some investigations relate to other issues such as reservation and cancellation clauses, commission payments and pricing behavior. For instance, in September 2016 the Swiss Price Surveillance Office initiated a market observation exercise with respect to the market position and the level of commissions of Booking.com in Switzerland. In Europe, investigations into Booking.com's price parity provisions were initiated in 2013 and 2014 by NCAs in France, Germany, Italy, Austria, Sweden, Ireland and Switzerland. A number of other NCAs have also looked at these issues. On April 21, 2015, the French, Italian and Swedish NCAs, working in close cooperation with the European Commission, announced that they had accepted "commitments" offered by Booking.com to resolve and close the investigations in France, Italy and Sweden. Under the commitments, Booking.com replaced its existing price parity agreements with accommodation providers with "narrow" price parity agreements. Under a "narrow" price parity agreement, subject to certain exceptions, an accommodation provider is still required to offer the same or better rates on Booking.com as it offers to a consumer directly online, but it is no longer required to offer the same or better rates on Booking.com as it offers to other OTCs. The commitments also allow an accommodation provider to, among other things, offer different terms and conditions (e.g., free WiFi) and availability to consumers that book with online travel companies that offer lower rates of commission or other benefits, offer lower rates to consumers that book through offline channels and continue to discount through, among other things, accommodation loyalty programs, as long as those rates are not published or marketed online. The commitments apply to accommodations in France, Italy and Sweden and were effective on July 1, 2015. The foregoing description is a summary only and is qualified in its entirety by reference to the commitments published by the NCAs on April 21, 2015. On July 1, 2015, Booking.com voluntarily implemented the commitments given to the French, Italian and Swedish NCAs throughout the European Economic Area and Switzerland. Nearly all NCAs in the European Economic Area have now closed their investigations following Booking.com's implementation of the commitments in their jurisdictions. Booking.com has also recently agreed with the NCAs in Australia, New Zealand and Georgia to implement the "narrow" price parity clause in these countries. However, the Australian NCA indicated in February 2017 that it is reassessing "narrow" price parity clauses between online travel agencies and accommodation providers. The Turkish NCA recently imposed fines on Booking.com following an investigation into Booking.com's "wide" parity clauses. Booking.com is in ongoing discussions with various NCAs in other countries regarding their concerns. The Company is currently unable to predict the long-term impact the implementation of these commitments will have on Booking.com's business, on investigations by other countries, or on industry practice more generally. On December 23, 2015, the German NCA issued a final decision prohibiting Booking.com's "narrow" price parity agreements with accommodations in Germany. The German NCA did not issue a fine, but has reserved its position regarding an order for disgorgement of profits. Booking.com is appealing the German NCA's decision. An Italian hotel association has appealed the Italian NCA's decision to accept the commitments by Booking.com. A working group of 10 European NCAs (France, Germany, Belgium, Hungary, Ireland, Italy, the Netherlands, Czech Republic, the United Kingdom and Sweden) was established by the European Commission in December 2015 to monitor the effects of the narrow price parity clause in Europe. This working group (the "ECN Working Group") issued questionnaires during 2016 to online travel agencies, including Booking.com and Expedia, meta-search sites and hotels about the narrow price parity clause. On April 6, 2017, the ECN Working Group published the results of this monitoring exercise. The report indicates that the introduction of the narrow price parity clause generally improved conditions for competition. Although neither the European Commission nor any of the participating NCAs has opened a new investigation following the publication of the report, the ECN Working Group decided to keep the sector under review and re-assess the competitive situation in due course. Separately, the French NCA, which conducted its own review of the effects of the narrow price parity clause, issued a report on February 9, 2017 stating that it has not ruled out the possibility of issuing an opinion at its own initiative if a change in competition requires it, and that it would continue to contribute actively to the ECN Working Group process. The Company is unable to predict how these appeals and the remaining investigations in other countries will ultimately be resolved, or whether further action in Europe will be taken as a result of the ECN Working Group's ongoing review. Possible outcomes include requiring Booking.com to amend or remove its rate parity clause from its contracts with accommodation providers in those jurisdictions and/or the imposition of fines. The Company is unable to predict the impact these possible outcomes might have on its business. In August 2015, French legislation known as the "Macron Law" became effective. Among other things, the Macron Law makes price parity agreements illegal, including the "narrow" price parity agreements agreed to by the French NCA in April 2015. Legislation in Austria prohibiting "narrow" price parity agreements (including the narrow parity clause) became effective on December 31, 2016. Similar legislation was approved by the Italian Senate on May 3, 2017, and will return to the Italian Chamber of Deputies for final approval. A motion to prohibit the narrow price parity clause is currently being discussed in the Swiss Parliament. It is not yet clear how the Macron Law and the Austrian legislation or the proposed Italian and Swiss legislation may affect the Company's business in the long term in France, Austria, Italy and Switzerland, respectively. Competition-related investigations, legislation or issues could also give rise to private litigation. For example, Booking.com is involved in private litigation in Sweden related to its "narrow" price parity provisions. We are unable to predict how this litigation will be resolved, or whether it will impact Booking.com's business in Sweden. Litigation Related to Travel Transaction Taxes The Company and certain third-party OTCs are currently involved in approximately thirty lawsuits, including certified and putative class actions, brought by or against U.S. states, cities and counties over issues involving the payment of travel transaction taxes (e.g., hotel occupancy taxes, excise taxes, sales taxes, etc.) related to the priceline.com business. Generally, the complaints allege, among other things, that the OTCs violated each jurisdiction's respective relevant travel transaction tax ordinance with respect to the charge and remittance of amounts to cover taxes under each law. The Company believes that the laws at issue generally do not apply to the services it provides, namely the facilitation of travel reservations, and, therefore, that it does not owe the taxes that are claimed to be owed. However, the Company has been involved in this type of litigation for many years, and state and local jurisdictions where these issues have not been resolved could assert that the Company is subject to travel transaction taxes and could seek to collect such taxes, retroactively and/or prospectively. From time to time, the Company has found it expedient to settle claims pending in these matters without conceding that the claims at issue are meritorious or that the claimed taxes are in fact due to be paid. The Company may also settle current or future travel transaction tax claims. On August 5, 2016, the tax appeal court of the State of Hawaii ruled that online travel companies, including the Company, owe General Excise Tax (GET) on the gross amounts collected from consumers on rental car reservations. The tax appeal court rejected the online travel companies' arguments that GET applies only to amounts retained by online travel companies and does not include amounts paid to rental car company suppliers. The online travel companies argued that GET should not apply to gross amounts charged to consumers for rental car reservations pursuant to the 2015 decision of the Hawaii Supreme Court in Travelocity.com, L.P., et al. v. Director of Taxation that GET applies to amounts retained by online travel companies for hotel reservations and not for gross amounts charged to consumers. The Company intends to appeal the tax appeal court decision to the Hawaii appellate courts. In order to appeal the decision, the Company must pay $13 million, which is the amount of the judgment entered on April 25, 2017. Litigation is subject to uncertainty and there could be adverse developments in these pending or future cases and proceedings. An unfavorable outcome or settlement of pending litigation may encourage the commencement of additional litigation, audit proceedings or other regulatory inquiries and also could result in substantial liabilities for past and/or future bookings, including, among other things, interest, penalties, punitive damages and/or attorneys’ fees and costs. An adverse outcome in one or more of these unresolved proceedings could have an adverse effect on the Company's results of operations or cash flows in any given operating period. However, the Company believes that even if the Company were to suffer adverse determinations in the near term in more of the pending proceedings than currently anticipated, given results to date it would not have a material impact on its liquidity or financial condition. As a result of the travel transaction tax litigation generally and other attempts by U.S. jurisdictions to levy similar taxes, the Company has established an accrual (including estimated interest and penalties) for the potential resolution of issues related to travel transaction taxes in the amount of approximately $27 million at both March 31, 2017 and December 31, 2016. The Company's legal expenses for these matters are expensed as incurred and are not reflected in the amount accrued. The actual cost may be less or greater, potentially significantly, than the liabilities recorded. An estimate for a reasonably possible loss or range of loss in excess of the amount accrued cannot be reasonably made. Patent Infringement On February 9, 2015, International Business Machines Corporation ("IBM") filed a complaint in the U.S. District Court for the District of Delaware against The Priceline Group Inc. and its subsidiaries KAYAK Software Corporation, OpenTable, Inc. and priceline.com LLC (the "Subject Companies"). In the complaint, IBM alleges that the Subject Companies have infringed and continue to willfully infringe certain IBM patents that IBM claims relate to the presentation of applications and advertising in an interactive service, preserving state information in online transactions and single sign-on processes in a computing environment and seeks unspecified damages (including a request that the amount of compensatory damages be trebled), injunctive relief and costs and reasonable attorneys’ fees. The Subject Companies believe the claims to be without merit and are contesting them. The Subject Companies asked the court to dismiss the case due to lack of patentable subject matter in the asserted patents, and on March 30, 2016 that motion was denied without prejudice to refiling later in the case. Concurrently with the litigation, the Subject Companies filed two Inter Partes Review ("IPR") petitions and four Covered Business Method ("CBM") petitions for the patents-in-suit with the U.S. Patent and Trademark Office (the "PTAB"). The PTAB denied one of the IPR petitions and granted one of the IPR petitions, and denied the four CBM petitions. Expert discovery has concluded and the parties have fully briefed and held oral argument on summary judgment motions. There is a mediation in the case scheduled for May 23, 2017 before the Magistrate Judge. Trial in the District Court is scheduled for August 2017. The Company does not believe a loss contingency is probable and reasonably estimable and therefore has not recorded a liability for this matter. French Tax Matter French tax authorities conducted an audit of Booking.com of the years 2003 through 2012. They are asserting that Booking.com has a permanent establishment in France and are seeking to recover what they claim are unpaid income taxes and value-added taxes. In December 2015, the French tax authorities issued Booking.com assessments for approximately 356 million Euros, the majority of which would represent penalties and interest. The Company believes that Booking.com has been, and continues to be, in compliance with French tax law, and the Company intends to contest the assessments. If the Company is unable to resolve the matter with the French authorities, it would expect to challenge the assessments in the French courts. In order to contest the assessments in court, the Company may be required to pay, upfront, the full amount or a significant part of any such assessments, though any such payment would not constitute an admission by it that it owes the taxes. At the end of 2016, French authorities announced their intention to also audit the tax years 2013 to 2015, which could result in additional assessments. Turkish Matter From time to time the Company has been subject to legal proceedings and claims regarding whether it is subject to local registration requirements, such as requirements to register as a travel agent. In March 2017, in connection with a lawsuit begun in 2015 by the Association of Turkish Travel Agencies claiming that Booking.com is required to meet certain registration requirements in Turkey, a Turkish court unexpectedly ordered Booking.com to suspend offering Turkish hotels and accommodations to Turkish residents. Although Booking.com is appealing the order and believes it to be without basis, this order has had, and is likely to continue to have, a negative impact on the Company's growth and results of operations. Other The Company accrues for certain legal contingencies where it is probable that a loss has been incurred and the amount can be reasonably estimated. Such accrued amounts are not material to the Company's consolidated balance sheets and provisions recorded have not been material to the Company's consolidated results of operations or cash flows. An estimate for a reasonably possible loss or range of loss in excess of the amount accrued cannot be reasonably made. From time to time, the Company has been, and expects to continue to be, subject to legal proceedings and claims in the ordinary course of business, including claims of alleged infringement of third-party intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources, divert management's attention from the Company's business objectives and adversely affect the Company's business, results of operations, financial condition and cash flows. Contingent Consideration for Business Acquisitions As of March 31, 2017 and December 31, 2016, the Company recognized a liability of approximately $9 million for each period for estimated contingent payments, which was considered a "Level 3" fair value measurement (see Note 5). The estimated acquisition-date contingent liability is based upon the probability-weighted average payments for specific performance factors from the acquisition date through the performance period which ends at March 31, 2019. The range of undiscounted outcomes for the estimated contingent payments is approximately $0 to $90 million. Building Construction In September 2016, the Company signed a turnkey agreement to construct an office building in the Netherlands, which will be the future headquarters of the Booking.com business. The turnkey agreement provided for payments by Booking.com of approximately 270 million Euros and consists of two components, land use rights and the building to be constructed. Upon signing this agreement, Booking.com paid approximately 48 million Euros to the developer, which included approximately 43 million Euros for the acquired land use rights and approximately 5 million Euros for the building construction. The land use rights are included in "Other assets" and the building construction-in-progress is included in "Property and equipment, net" in the Unaudited Consolidated Balance Sheets at March 31, 2017 and December 31, 2016. The land use rights asset and required future lease payments to the Municipality in Amsterdam of approximately 60 million Euros are recognized as rent expense on a straight-line basis over the remaining 49-year term of the lease and are recorded in general and administrative expense in the statements of operations. Booking.com expects to pay approximately 34 million Euros related to the building construction later in 2017, with the remainder of payments being paid periodically beginning in 2018 until the expected completion of the building in late 2020. The Company expects all future payments to be made from its international cash. Acquisition of Momondo Group On February 7, 2017, the Company signed a definitive agreement to acquire the Momondo Group, which operates the travel meta-search websites Momondo and Cheapflights. The Company will use approximately $550 million of its international cash to fund this acquisition. The transaction is expected to close later in the year, subject to regulatory approval.

The Company accrues for certain legal contingencies where it is probable that a loss has been incurred and the amount can be reasonably estimated. Such accrued amounts are not material to the Company's consolidated balance sheets and provisions recorded have not been material to the Company's consolidated results of operations or cash flows. An estimate for a reasonably possible loss or range of loss in excess of the amount accrued cannot be reasonably made.

From time to time, the Company has been, and expects to continue to be, subject to legal proceedings and claims in the ordinary course of business, including claims of alleged infringement of third-party intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources, divert management's attention from the Company's business objectives and adversely affect the Company's business, results of operations, financial condition and cash flows.

Contingent Consideration for Business Acquisitions

As of March 31, 2017 and December 31, 2016, the Company recognized a liability of approximately $9 million for each period for estimated contingent payments, which was considered a "Level 3" fair value measurement (see Note 5). The estimated acquisition-date contingent liability is based upon the probability-weighted average payments for specific performance factors from the acquisition date through the performance period which ends at March 31, 2019. The range of undiscounted outcomes for the estimated contingent payments is approximately $0 to $90 million.

The Company expects all future payments to be made from its international cash.

Acquisition of Momondo Group

On February 7, 2017, the Company signed a definitive agreement to acquire the Momondo Group, which operates the travel meta-search websites Momondo and Cheapflights. The Company will use approximately $550 million of its international cash to fund this acquisition. The transaction is expected to close later in the year, subject to regulatory approval.
