(*) Less than $0.01. (**) December 31, 2018 and 2017 options data represents the number of shares adjusted to retroactively reflect the 1:15 Reverse Split effected on September 4, 2018. Refer to Note 1 for further information. Compensation expense recorded by the Company in respect of its stock-based employee compensation awards in accordance with ASC 718-10 for the year ended December 31, 2018 and 2017 was $ 1,399 and $254, respectively. The fair value of the stock options is estimated at the date of grant using Black-Scholes options pricing model with the following weighted-average assumptions:
|  | Year ended December 31, 2018 |  |  | Year ended December 31, 2017 |
Expected volatility |  |  | 99.4 | % |  |  | 122.5 | %
Risk-free interest |  |  | 2.39 | % |  |  | 1.64 | %
Dividend yield |  |  | 0 | % |  |  | 0 | %
Expected life of up to (years) |  |  | 5.24 |  |  |  | 6.25 |
Shares Issued to Service Provider In connection with the Merger, the Company issued an aggregate of 525,706 restricted shares (7,802,639 restricted shares before the Reverse Split) of its common stock to certain advisors. The fair value of the award of approximately $10,000 was estimated based on the share price of the common stock of $19.2 ($1.28 before the Reverse Split) as of the date of grant. During 2017, the Company issued an aggregate of 8,085 nonrefundable shares (120,000 nonrefundable shares before the Reverse Split) of common stock to a consultant as part of investor relations services. The Company recorded expenses of approximately $225 with respect to the issuance of these shares included in general and administrative expenses. On May 24, 2018 the Company issued an aggregate of 6,738 nonrefundable shares (100,000 nonrefundable shares before the Reverse Split) of common stock to CardioSert as part of certain patent acquisition. The Company recorded expenses of approximately $74 with respect to the issuance of these shares included in research and development expenses. Repurchase of Shares The Company had intended to enter into a definitive agreement with up to three Israeli shareholders, some of whom are directors of the Company, that were former shareholders of Microbot Israel, pursuant to which the Company would repurchase, at a discount on the fair value of the share at the date of repurchase, up to $500 of common stock held by them, in the aggregate, if and to the extent such shareholders are unable to sell enough of their shares to cover certain of their Israeli tax liabilities resulting from the Merger. Such repurchase(s), if any, would occur only after the two-year anniversary of the Merger. The transaction would have been subject to negotiating final terms and entering into definitive agreements with such shareholders. The Company evaluated whether an embedded derivative that requires bifurcation exists within such shares that may be subject to repurchase. The Company concluded the fair value of such derivative instrument would be nominal and, in any case, would represent an asset to the Company as (a) the settlement requires acquiring the shares at a discount on the fair market value of the share at the time of re purchase and in no circumstances the acquisition price will be higher than approximately one dollar per share (representing 25% discount on the fair market value of the share at the merger closing date) and (b) it is assumed that the selling shareholders would use such right as last resort as such repurchase at a discount on the fair market value of such shares results in a loss to be incurred by the selling shareholders. In accordance with ASC 480-10-S99-3A (formerly EITF D-98), the Company classified the maximum amount it may be required to pay in the event the repurchase right is exercised ($500) as temporary equity. As of December 31, 2018, the Company determined that no obligation remained to enter into any such definitive agreement as the two-year anniversary of the Merger was in November 2018 and therefore there was no liability for the Company to repurchase any shares from the three Israeli shareholders.
