Toys "R" Us, which is partly owned by KKR (NYSE:KKR) and Vornado Realty Trust (NYSE:VNO), has finally ended its plans to go public, due to "unfavorable market conditions" and a change in CEO. The move comes a month after boss Gerald Storch said he was stepping down, and as Q4 revenue dropped 2.6% to $5.77B and profit slumped 30% to $239M.
