discussed below). As a result of the Merger closing, TerraForm Power is no longer a controlled affiliate of SunEdison, Inc. and is now a controlled affiliate of Brookfield.
At the effective time of the Merger, each share of Class A common stock of TerraForm Power issued and outstanding immediately prior to the effective time of the Merger, with the exception of certain excluded shares, was converted into the right to, at the holder’s election and subject to proration as described below, either (i) receive $9.52 per Class A Share, in cash, without interest (the “Per Share Cash Consideration”) or (ii) retain one share of Class A common stock, par value $0.01 per share, of the surviving corporation (the “Per Share Stock Consideration,” and, together with the Per Share Cash Consideration, without duplication, the “Per Share Merger Consideration”). Issued and outstanding shares included shares issued in connection with the SunEdison Settlement Agreement as more fully described above and shares underlying outstanding RSUs of the Company under the Company’s 2014 Second Amended and Restated Long-Term Incentive Plan (the “2014 LTIP”). At the effective time of the Merger, any vesting conditions applicable to any Company RSU outstanding immediately prior to the effective time of the Merger under the 2014 LTIP were automatically and without any required action on the part of the holder, deemed to be satisfied in full, and such Company RSU was canceled and converted into the right to receive the Per Share Merger Consideration, including the election of the Per Share Stock Consideration or the Per Share Cash Consideration in respect of each share (in the case of RSUs subject to performance conditions, with such conditions deemed satisfied at “target” levels), less any tax withholdings. The Per Share Stock Consideration was subject to proration in the event that the aggregate number of Class A Shares for which an election to receive the Per Share Stock Consideration exceeded 49% of the TerraForm Power fully diluted share count (the “Maximum Stock Consideration Shares”). Additionally, the Per Share Cash Consideration was subject to proration in the event that the aggregate number of Class A shares for which an election to receive the Per Share Cash Consideration exceeded the TerraForm Power fully diluted share count minus (i) the Maximum Stock Consideration Shares, (ii) any Class A shares currently held by affiliates of Brookfield, and (iii) any shares for which the holders seek appraisal under Delaware law. Based on the results of the consideration election, the elections of the Per Share Stock Consideration were oversubscribed and the proration ratio was 62.6%, which meant that stockholders electing to receive 100% of their merger consideration in stock retained 62.6% of their Class A shares in the Merger and received cash consideration in respect of 37.4% of their shares.
On October 16, 2017, in connection with the consummation of the Merger, the Company entered into a registration rights agreement (the “SunEdison Registration Rights Agreement”) with SunEdison, Inc., SunEdison Holdings Corporation (“SHC”) and SUNE ML 1, LLC (“SML1”). The SunEdison Registration Rights Agreement governed the rights of SunEdison, Inc., SHC, SML1 and certain permitted assigns with respect to the registration for resale of Class A shares held by them immediately following the Merger. The Company registered these shares in December of 2017, and these shares were distributed by SunEdison, Inc., SHC and SML1 to certain creditors under the plan of reorganization in connection with SunEdison's emergence from bankruptcy in December of 2017.
Upon the consummation of the Merger, the Company's certificate of incorporation was amended and restated. TerraForm Power now has 100,000,000 authorized shares of preferred stock, par value $0.01 per share, and 1,200,000,000 authorized shares of Class A common stock, par value $0.01 per share. There are no other authorized classes of shares, and the Company does not have any issued shares of preferred stock.
Issuance of Class A Common Stock to Affiliates
On June 11, 2018, TerraForm Power entered into a Class A Common Stock Purchase Agreement (“Share Purchase Agreement”) with Orion Holdings and BBHC Orion Holdco L.P. (collectively, the “Purchasers”), both affiliates of Brookfield. Pursuant to the Share Purchase Agreement, the Purchasers purchased in a private placement a total of 60,975,609 shares of TerraForm Power’s Class A common stock for a price per share of $10.66, representing total consideration of approximately $650.0 million. No underwriting discounts or commissions were paid with respect to this private placement. These newly issued shares of TerraForm Power were not registered with the SEC in reliance on Section 4(a)(2) of the Securities Act and the acknowledgment of each of the Purchasers that it is an “accredited investor” within the meaning of Rule 501(a) of Regulation D of the Securities Act or a “qualified institutional buyer” under Rule 144A of the Securities Act. As a result of this private placement, affiliates of Brookfield now hold approximately 65% of TerraForm Power’s Class A common stock.
The proceeds of the offering were used by the Company to pay a portion of the purchase price of the Tendered Shares of Saeta. The purchase of $650 million of TerraForm Power’s Class A shares by the Purchasers was made pursuant to support agreement that the Company had entered into with Brookfield, dated February 6, 2018, and amended on May 28, 2018, at the previously agreed backstop price of $10.66 per share.
