Decommissioning trust assets description       (i) the completion of the Business Combination; (ii) the redemption of 100% of the shares of common stock included in the units sold in the Offering (the “public shares”) if the Company is unable to complete a Business Combination within 15 months (or 18 months as described below) from the closing of the Offering on December 12, 2017 (subject to the requirements of law); or (iii) the redemption of the public shares in connection with a stockholder vote to amend the Company’s amended and restated certificate of incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of its public shares if it does not complete its initial Business Combination within 15 months (or 18 months as described below) from the closing of the Offering on December 12, 2017.

Business combination, description       (i) seek stockholder approval of the Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest but less taxes payable, or (ii) provide stockholders with the opportunity to have their shares redeemed by the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to commencement of the tender offer, including interest but less taxes payable. The decision as to whether the Company will seek stockholder approval of the Business Combination or allow stockholders to redeem their shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek stockholder approval unless a vote is required by New York Stock Exchange rules. If the Company seeks stockholder approval, it will complete its Business Combination only if a majority of the outstanding shares of common stock voted are voted in favor of the Business Combination. However, in no event will the Company redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001 upon consummation of a Business Combination. In such case, the Company would not proceed with the redemption of its public shares and the related Business Combination, and instead may search for an alternate Business Combination.
