Description of Business and Operations	1. Description of Business and Operations Description of Business - CF Finance Acquisition Corp. (the “Company”) was incorporated in Delaware on July 9, 2014. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). Although the Company is not limited to a particular industry or sector for the purpose of consummating a Business Combination, the Company intends to focus its search on companies operating in the financial services or real estate industries. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of June 30, 2020, the Company had not yet commenced operations. All activity for the three and six months ended June 30, 2020 and 2019 relates to the Company’s formation and Public Offering described below and, subsequent to the Public Offering, efforts have been directed toward locating and completing a suitable Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company has generated non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Public Offering. The Company has selected December 31^st as its fiscal year end. The Company’s Sponsor is CF Finance Holdings, LLC (the “Sponsor”). The registration statement for the Public Offering (see Note 3) was declared effective by the United States Securities and Exchange Commission (the “SEC”) on December 12, 2018. The Company intends to finance a Business Combination with the proceeds of approximately $282,600,000 (approximately $276,503,600, as adjusted for the redemption described below) from the Public Offering, $6,000,000 from the Private Placement (see Note 4) and approximately $2,826,000 (approximately $5,315,700, as adjusted for the redemption described below) from the Sponsor loan (see Note 4). Offering costs for the Public Offering amounted to approximately $5,585,900, consisting of $5,100,000 of underwriting fees and approximately $485,900 of other costs. On June 15, 2020, the stockholders of the Company approved the extension of the termination of the Company from June 17, 2020 to September 17, 2020. In conjunction with the termination date extension vote, public stockholders exercised their right to elect to redeem their 593,700 shares of Common Stock. $6,096,437 was withdrawn from the Trust Account in connection with the redemption of such shares. In addition, in conjunction with the termination date extension, the Sponsor committed to contribute an additional $0.09 per remaining Public Share to the Trust Account in the form of a Sponsor Loan. On June 17, 2020, an additional $2,489,824 was contributed to the Trust Account. 1. Description of Business and Operations (continued) Initial Business Combination - The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering and the sale of Private Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the assets held in the Trust Account (as defined below) (excluding taxes payable on income earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Upon the closing of the Public Offering and the underwriter’s partial exercises of the over-allotment option, an amount equal to $10.10 per Unit sold in the Public Offering, including the proceeds of the Private Placement Units and Sponsor Loan (see Note 4), was held in a Trust Account, with Continental Stock Transfer & Trust Company acting as trustee. The proceeds are invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 180 days or less or in any open-ended Investment Company that holds itself out as a money market fund selected by the Company meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below. The Company will provide its holders of the outstanding shares of its Class A common stock, par value $0.0001 (“Class A common stock”), sold in the Public Offering (the “public stockholders”) with the opportunity to redeem all or a portion of their public shares (the “Public Shares”) upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares (see Note 3) for a pro rata portion of the amount then in the Trust Account (initially $10.10 per Public Share).These Public Shares will be recorded at a redemption value and classified as temporary equity upon the completion of the Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 Distinguishing Liabilities from Equity. In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the SEC and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law or rules of the stock exchange, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor (the “initial stockholders”), officers and directors have agreed to vote their Founder Shares (see Note 4) and any Public Shares purchased during or after the Public Offering in favor of a Business Combination. In addition, the initial stockholders, officers and directors have agreed to waive their redemption rights with respect to their Founder Shares and shares included in the Private Placement Units held by the initial stockholders, officers and directors in connection with the completion of a Business Combination. 1. Description of Business and Operations (continued) Notwithstanding the foregoing, the Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Class A common stock sold in the Public Offering, without the prior consent of the Company. The initial stockholders, officers and directors have agreed not to propose an amendment to the Amended and Restated Certificate of Incorporation (i) that would affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination or (ii) with respect to any other provision relating to stockholders’ rights or pre-business combination activity, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. Forward Purchase Contract – In connection with the Public Offering, the Sponsor committed, pursuant to a forward purchase contract with the Company, to purchase, in a Private Placement for gross proceeds of $30,000,000 to occur concurrently with the consummation of an initial Business Combination, 3,000,000 of the Company’s Units on substantially the same terms as the sale of Units in the initial Public Offering at $10.00 per Unit, and 750,000 shares of Class A common stock. In connection with the execution of the Transaction Agreement (as defined in Note 8) regarding its initial Business Combination (see Note 8), on August 2, 2020, the Company and the Sponsor entered into Amendment No. 1 to Forward Purchase Contract, pursuant to which, among other things, the Sponsor agreed to purchase, subject to the Company’s consummation of a Business Combination with GCM PubCo (as defined in Note 8) and its affiliates, to a reduction in the total equity issuable under such contract to a total of 3,500,000 shares of GCM PubCo Class A common stock and 1,500,000 GCM PubCo common warrants, for the same $30,000,000 in gross proceeds. The funds from the sale of Company’s securities in the forward purchase contract, as amended, will be used as part of the consideration to the sellers in the initial Business Combination; any excess funds from this Private Placement will be used for working capital in the post-transaction company. This commitment is independent of the percentage of stockholders electing to redeem their Public Shares and provides the Company with a minimum funding level for the initial business combination. Failure to Consummate a Business Combination - If the Company is unable to complete a Business Combination by September 17, 2020 (which was originally June 17, 2020, but has been extended due to the shareholder approval of an extension of time) (or if such date is extended at a duly called meeting of our stockholders, such later date) (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. The Combination Period extension from June 17, 2020 to September 17, 2020 was approved by stockholders at the stockholder’s meeting on June 15, 2020. 1. Description of Business and Operations (continued) The initial stockholders, officers and directors have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders, officers and directors acquire Public Shares in or after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.10 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the underwriter of the Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, except for the Company’s independent registered public accounting firm, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. The Trust Account - The proceeds in the Trust Account will be invested only in U.S. government treasury bills with a maturity of one hundred and eighty (180) days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940 which invest only in direct U.S. government obligations. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Company’s initial Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence expenses for prospective acquisition targets and continuing general and administrative expenses. As of June 30, 2020 and December 31, 2019, investment securities in the Trust Account consisted of $286,565,390 and $291,761,159 in money market funds. The Amended and Restated Certificate of Incorporation, as further amended on June 15, 2020, provides that, other than the withdrawal of interest to pay taxes, if any, none of the funds held in the Trust Account will be released until the earlier of: (i) the completion of the Business Combination; or (ii) the redemption of 100% of the Public Shares included in the Units being sold in the Public Offering if the Company is unable to complete a Business Combination by the Combination Period, subject to the requirements of law. During three and six months ended June 30, 2020, $136,882 and $336,882 of the proceeds from the Trust Account were used to pay taxes, respectively.

Forward Purchase Contract – In connection with the Public Offering, the Sponsor committed, pursuant to a forward purchase contract with the Company, to purchase, in a Private Placement for gross proceeds of $30,000,000 to occur concurrently with the consummation of an initial Business Combination, 3,000,000 of the Company’s Units on substantially the same terms as the sale of Units in the initial Public Offering at $10.00 per Unit, and 750,000 shares of Class A common stock. In connection with the execution of the Transaction Agreement (as defined in Note 8) regarding its initial Business Combination (see Note 8), on August 2, 2020, the Company and the Sponsor entered into Amendment No. 1 to Forward Purchase Contract, pursuant to which, among other things, the Sponsor agreed to purchase, subject to the Company’s consummation of a Business Combination with GCM PubCo (as defined in Note 8) and its affiliates, to a reduction in the total equity issuable under such contract to a total of 3,500,000 shares of GCM PubCo Class A common stock and 1,500,000 GCM PubCo common warrants, for the same $30,000,000 in gross proceeds.

1. Description of Business and Operations (continued)

The initial stockholders, officers and directors have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders, officers and directors acquire Public Shares in or after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.10 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the underwriter of the Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, except for the Company’s independent registered public accounting firm, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

The Trust Account - The proceeds in the Trust Account will be invested only in U.S. government treasury bills with a maturity of one hundred and eighty (180) days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940 which invest only in direct U.S. government obligations. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Company’s initial Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence expenses for prospective acquisition targets and continuing general and administrative expenses. As of June 30, 2020 and December 31, 2019, investment securities in the Trust Account consisted of $286,565,390 and $291,761,159 in money market funds. The Amended and Restated Certificate of Incorporation, as further amended on June 15, 2020, provides that, other than the withdrawal of interest to pay taxes, if any, none of the funds held in the Trust Account will be released until the earlier of: (i) the completion of the Business Combination; or (ii) the redemption of 100% of the Public Shares included in the Units being sold in the Public Offering if the Company is unable to complete a Business Combination by the Combination Period, subject to the requirements of law.

During three and six months ended June 30, 2020, $136,882 and $336,882 of the proceeds from the Trust Account were used to pay taxes, respectively.
