Liquidity and Capital Resources
As of June 30, 2023, we had approximately $6,378 of cash and cash equivalents (excluding restricted cash), $25,526 in marketable securities, and total current assets of $36,128. Our total current liabilities balance, which includes accounts payable, deferred revenue, accrued expenses, and operating lease liabilities was approximately $9,266 as of June 30, 2023 and $10,956 as of December 31, 2022. The working capital surplus was $26,862 as of June 30, 2023, compared to a working capital surplus of $36,376 as of December 31, 2022.
We have carried out an assessment of our ability to continue as a going concern. As of the date of the report, we believe that our Company has sufficient liquidity to fund operations for the next twelve months. Our primary liquidity and capital requirements are for the maintenance of our current XpresSpa and Treat locations and brand, as well as the expansion outside the airports. During the six months ended June 30, 2023 and 2022, we used $8,618 and $8,615 in operations, respectively.
On August 31, 2021, our board of directors initially authorized a stock repurchase program that permitted the purchase and repurchase of up to 15 million shares of our common stock through September 15, 2022. In May 2022, the Board increased the share repurchase program by an additional 10 million shares and extended its effectiveness through September 15, 2023. Under this stock repurchase program, management has discretion in determining the conditions under which shares may be purchased from time to time. The program does not require us to repurchase any specific number of shares, and may be modified, suspended or terminated at any time without prior notice.
Pursuant to our share repurchase program, we purchased 8,480,850 shares for $12,116 and retired 7,142,446 of these purchased shares during the six months ended June 30, 2022, and the remaining 1,338,404 shares were retired on August 3, 2022. We did not repurchase any shares during the six months ended June 30, 2023. As of June 30, 2023, we were permitted to repurchase approximately 0.8 million additional shares under this program.

Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Exchange Act) that are designed to ensure that information required to be disclosed in Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer (Principal Financial and Accounting Officer), as appropriate, to allow timely decisions regarding required disclosure.
As of June 30, 2023, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Interim Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures.
This type of evaluation is performed on a quarterly basis so that conclusions of management, including our Chief Executive Officer and the Interim Chief Financial Officer, concerning the effectiveness of the disclosure controls can be reported in
