Stockholders' Equity [Abstract]
STOCKHOLDERS' EQUITY	NOTE 6 – STOCKHOLDERS’ EQUITY The Company’s common stock and warrants are listed on the NASDAQ Capital Market under the symbols “LIND” and “LINDW,” respectively. As of September 30, 2017 and December 31, 2016, there were 45,155,621 and 45,659,762 shares of common stock outstanding, respectively, and 10,673,015 and 11,186,387 warrants outstanding (inclusive of certain warrants issued to the Company’s founders on substantially the same terms as all other warrants), respectively. *Capital Stock* The Company has a total of 201,000,000 authorized shares of capital stock, consisting of 1,000,000 shares of preferred stock, $0.0001 par value and 200,000,000 shares of common stock, $0.0001 par value. *Stock and Warrant Repurchase Plan* In November 2015, the Company’s Board of Directors approved a $20.0 million stock and warrant repurchase plan and in November 2016, increased the authorization by $15.0 million to a total of $35.0 million. This Repurchase Plan authorizes the Company to purchase from time to time the Company’s outstanding common stock and warrants through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions based on market and business conditions, applicable legal requirements and other factors. Any shares and warrants repurchased will be retired. The Repurchase Plan has no time deadline and will continue until otherwise modified or terminated at the sole discretion of the Company’s Board of Directors at any time. During the three months ended September 30, 2017, the Company did not repurchase shares of common stock or warrants. During the nine months ended September 30, 2017 the Company repurchased 547,058 shares of common stock for $5.1 million and 513,372 warrants for $1.1 million. The Company has cumulatively repurchased 855,776 shares of common stock for $8.1 million and 5,426,985 warrants for $13.9 million, since plan inception. *2017 Long-Term Incentive Compensation* In March 2017, the Company’s compensation committee (or a subcommittee thereof) approved awards of restricted stock units (“RSUs”) and performance share units (“PSUs”) to key employees under the Company’s 2015 Long-Term Incentive Plan. The Company granted 171,393 RSUs on April 3, 2017 at a grant price of $8.98. The RSU’s will vest in three equal annual installments following the April 2017 grant date, subject to the recipient’s continued employment or service with us or our subsidiaries on the applicable vesting date. The PSUs are performance-vesting equity incentive awards that will be earned based on our performance against metrics relating to annual Adjusted EBITDA, annual revenue, and guest satisfaction. Awards will vest after a three-year performance period and may be earned at a level ranging from 0%-200% of the number of PSUs granted, depending on performance. On April 3, 2017, the Company awarded 126,953 of targeted PSUs with the number of shares determined based upon the closing price of our common stock on March 31, 2017 of $8.96. Based on the financial statements as of September 30, 2017, the Company assessed the applicable metrics related to the PSU grants, determined the blended probability of achieving the performance metrics and valued the awards based on the fair value at the date of grant with the amount of stock compensation expense determined based on the number PSU’s expected to vest. *2016 CEO Share Allocation Plan* In April 2016, the Company’s Board of Directors adopted the 2016 CEO Share Allocation Plan and in June 2016, the Company’s stockholders approved the 2016 CEO Share Allocation Plan, pursuant to which the Company may grant awards covering up to 1,000,000 shares of the Company’s common stock in the form of restricted stock, restricted stock units, and/or other stock- or cash- based awards to eligible employees and other service providers of the Company. The 2016 CEO Share Allocation Plan was adopted in connection with a contribution agreement that the Company entered into with Sven-Olof Lindblad, Chief Executive Officer and President of the Company, pursuant to which Mr. Lindblad is authorized to transfer up to 1,000,000 shares from his holdings of the Company’s common stock (i.e., an equivalent number of shares as is reserved for issuance under the 2016 CEO Share Allocation Plan) (the “Contribution Shares”) to the Company as a contribution to the capital of the Company. Mr. Lindblad will not receive any consideration in exchange for the Contribution Shares. However, as a condition to the contribution of any Contribution Shares, the Company must grant awards under the 2016 CEO Share Allocation Plan, such that the number of Contribution Shares that Mr. Lindblad actually contributes to the Company will equal the number of shares corresponding to awards granted under the plan. The contribution of the Contribution Shares by Mr. Lindblad to the Company will effectively reduce the number of shares of the Company’s common stock that are outstanding by the same number of shares that are issued under the 2016 CEO Share Allocation Plan (or a lesser number in the event awards are settled in cash). Such contributions will be effective as of the date the Company grants corresponding awards under the 2016 CEO Share Allocation Plan. The administrator may amend, suspend or terminate the 2016 CEO Share Allocation Plan at any time. On January 10, 2017, Mr. Lindblad contributed to the Company and the Company thereafter granted, 716,550 restricted shares at a grant price of $9.65. The grants vest in three equal installments with the first vesting date of January 10, 2017 and the remaining two vesting dates of January 10, 2018 and 2019, respectively. On January 10, 2017, 238,850 restricted shares vested, with 93,320 of such shares withheld and retired by the Company in order to pay the payroll withholdings to cover the transactions. *Stock Options* On August 2, 2017, 95,542 options were exercised at a market price on the date of exercise of $9.76 per share and a grant price of $1.76 per share, 17,229 shares were withheld by the Company to provide the $0.2 million required to exercise the options. In addition, 28,192 shares were withheld by the Company in order to pay the payroll withholding taxes for the transactions. The balance of 50,121 option shares were issued as a result of the transaction. During March 2017, an additional 95,542 options were exercised. Using the market price at the date of exercise of $8.72 per share and the grant price of $1.76 per share, 19,284 shares were withheld by the Company to provide the $0.2 million required to exercise the options. In addition, 23,145 of such shares were withheld by the Company in order to pay the payroll withholding taxes for the transactions. The balance of 53,113 option shares were issued as a result of the transaction.
