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