Commitments and Contingencies From time to time, the Company is subject to various claims and legal proceedings, either asserted or unasserted, that arise in the ordinary course of business. The Company accrues for legal contingencies if the Company can estimate the potential liability and if the Company believes it is probable that the case will be ruled against it. If a legal claim for which the Company did not accrue is resolved against it, the Company would record the expense in the period in which the ruling was made. The Company believes that the likelihood of an ultimate amount of liability, if any, for any pending claims of any type (alone or combined) that will materially affect the Companys financial position, results of operations or cash flows is remote. The ultimate outcome of any litigation is uncertain, however, and unfavorable outcomes could have a material negative impact on the Companys financial condition and operating results. Regardless of outcome, litigation can have an adverse impact on the Company because of defense costs, negative publicity, diversion of management resources and other factors. The Company was formed as a result of a combination and merger of entities founded by the Companys principal stockholder, Ralph Bartel. In 2002, Travelzoo.com Corporation was merged into Travelzoo. Under and subject to the terms of the merger agreement, holders of promotional shares of Travelzoo.com Corporation (Netsurfers) who established that they had satisfied certain prerequisite qualifications were allowed a period of 2 years following the effective date of the merger to receive one share of Travelzoo in exchange for each share of common stock of Netsurfers. In 2004, two years following the effective date of the merger, certain promotional shares remained unexchanged. As the right to exchange these promotional shares expired, no additional shares were reserved for issuance. Thereafter, the Company began to offer a voluntary cash program for those who established that they had satisfied certain prerequisite qualifications for Netsurfers promotional shares as further described below. During 2010 through 2014, the Company became subject to unclaimed property audits of various states in the United States related to the above unexchanged promotional shares and completed settlements with all states. Although the Company has settled the unclaimed property claims with all states, the Company may still receive inquiries from certain potential Netsurfers promotional stockholders that had not provided their state of residence to the Company by April 25, 2004. Therefore, the Company is continuing its voluntary program under which it makes cash payments to individuals related to the promotional shares for individuals whose residence was unknown by the Company and who establish that they satisfy the original conditions required for them to receive shares of Netsurfers, and who failed to submit requests to convert their shares into shares of Travelzoo within the required time period. This voluntary program is not available for individuals whose promotional shares have been escheated to a state by the Company, except those individuals for which their residence was unknown to the Company. The Company did not make any material payments for 2019 and 2018. The total cost of this program cannot be reliably estimated because it is based on the ultimate number of valid requests received and future levels of the Companys common stock price. The Companys common stock price affects the liability because the amount of cash payments under the program is based in part on the recent level of the stock price at the date valid requests are received. The Company does not know how many of the requests for shares originally received by Netsurfers in 1998 were valid, but the Company believes that only a portion of such requests were valid. In order to receive payment under this voluntary program, a person is required to establish that such person validly held shares in Netsurfers. The Company leases office space in Australia, Canada, China, France, Germany, Hong Kong, Japan, Singapore, Spain, the U.K., and the U.S. under operating leases which expire between February 2020 and November 2024. Rent expense was $5.8 million for each of the years ended December 31, 2019 and 2018 , respectively. The Companys rental income from sublease was approximately $347,000 and $123,000 for the years ended December 31, 2019 and 2018. See Note 13 - Leases for more information. The Company has purchase commitments aggregating approximately $50,000 as of December 31, 2019, which represent the minimum obligations the Company has under agreements with certain suppliers. These minimum obligations are less than the Company's projected use for those periods. Payments may be more than the minimum obligations based on actual use.
