GAIN ON SALE OF BUILDING

During 2015, we sold an office building in our San Clemente location to George A. Lopez, M.D., a member of our Board of Directors. 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.
