Gain on Sale of Building

On September 30, 2015, we sold an office building in our San Clemente location to Dr. Lopez. The building was sold for $3.6 million, its fair market value as determined by a third party. The net book value of the land and building was $2.5 million, resulting in a gain on the sale of the land and building of $1.1 million.
