[1] At the time we purchased one of our urgent and primary care centers, we allocated $600,000 of the purchase price to a contract held by the acquired center that related to non-urgent care services. During the quarter ended June 30, 2015, we suspended our provision of services under that contract and have recorded a one-time impairment charge of $520,000 relating to the unamortized balance of that intangible asset.
