On January 1, year 1, Melvin Corporation promises to "unconditionally" transfer a building that cost $100,000 (appraised recently at $300,000) to the Vivian Company on January 1, year 2 for a boat she bought for $250,000. As of December 31, year 2, Melvin still has not transferred title to the building, although it received title to the boat. How should Vivian and Melvin record these transactions?
