On January 1, 2017, when a share of B Corp is available in the public market for $1 a share, X (in the long position) agrees to purchase 100 shares of B Corp stock from Y (in the short position) on December 31, 2017 for $105 (the forward price, representing $1.05 per share). If, on December 31, 2017, B Corp shares are trading at $1.15 per share, and the parties agreed to cash- settle the forward contract, Y would pay how much to X?
