The Company establishes reserves for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Management has also identified certain other legal matters where we believe an unfavorable outcome is not probable and, therefore, </span><span style="font-family:inherit;font-size:10pt;"><span>no</span></span><span style="font-family:inherit;font-size:10pt;"> reserve is established. Although management currently believes that resolving claims against us, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. The Company also evaluates other contingent matters, including income and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of </span><span style="font-family:inherit;font-size:10pt;"><span>one</span></span><span style="font-family:inherit;font-size:10pt;"> or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company.

("Tinder"), an operating business of Match Group, filed a lawsuit in New York state court against IAC and Match Group. </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">See Sean Rad et al. v. IAC/InterActiveCorp and Match Group, Inc.</span><span style="font-family:inherit;font-size:10pt;">, No. 654038/2018 (Supreme Court, New York County). The complaint alleges that in 2017, the defendants: (i) wrongfully interfered with a contractually established process for the independent valuation of Tinder by certain investment banks, resulting in a substantial undervaluation of Tinder and a consequent underpayment to the plaintiffs upon exercise of their Tinder stock options, and (ii) then wrongfully merged Tinder into Match Group, thereby depriving one of the plaintiffs (Mr. Rad) of his contractual right to later valuations of Tinder on a stand-alone basis. The complaint asserts claims for breach of contract, breach of the implied covenant of good faith and fair dealing, unjust enrichment, interference with contractual relations (as against Match Group only), and interference with prospective economic advantage, and seeks compensatory damages in the amount of at least </span><span style="font-family:inherit;font-size:10pt;"><span>$2 billion</span></span><span style="font-family:inherit;font-size:10pt;">, as well as punitive damages. On August 31, 2018, four plaintiffs who were still employed by Match Group filed a notice of discontinuance of their claims without prejudice, leaving the </span><span style="font-family:inherit;font-size:10pt;"><span>six</span></span><span style="font-family:inherit;font-size:10pt;"> former employees as the remaining plaintiffs.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:29px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On October 9, 2018, the defendants filed a motion to dismiss the complaint on various grounds, including that the 2017 valuation of Tinder by the investment banks was an expert determination any challenge to which is both time-barred under applicable law and available only on narrow substantive grounds that the plaintiffs have not pleaded in their complaint; the plaintiffs opposed the motion. On June 13, 2019, the court issued a decision and order (i) granting the motion to dismiss the claims for breach of the implied covenant of good faith and fair dealing and for unjust enrichment, (ii) granting the motion to dismiss the merger-related claim for breach of contract as to </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> of the remaining </span><span style="font-family:inherit;font-size:10pt;"><span>six</span></span><span style="font-family:inherit;font-size:10pt;"> plaintiffs, and (iii) otherwise denying the motion to dismiss. The defendants have appealed from the court's partial denial of their motion to dismiss. On June 3, 2019, the defendants filed a second motion to dismiss based upon certain provisions of the plaintiffs' agreement with a litigation funding firm; the plaintiffs have opposed the motion, which remains pending. Discovery in the case is proceeding. IAC and Match Group believe that the allegations in this lawsuit are without merit and will continue to defend vigorously against it.</span></div>
