Shares of TerraForm Power Inc (NASDAQ: TERP) have finally stabilized after Brookfield Asset Management (NYSE: BAM) agreed to buy a majority stake in the company and become its sponsor. SunEdison, which founded TerraForm Power, went bankrupt last year, leaving the yieldco with an uncertain future and unable to file quarterly reports, since it shared back-office functions with SunEdison, leaving investors with little information on the stock.
