The total purchase price of this acquisition is 630 million Canadian dollars (approximately 460 million U.S. dollars*), subject to customary working capital and other adjustments. Following the completion of this transaction, together with SMEJ’s existing approximately 39% equity interest, SMEJ and SPE will indirectly own an 80% equity interest in Peanuts, and Peanuts will become a consolidated subsidiary of Sony.
