BUSINESS ACQUISITION

BUSINESS ACQUISITIONS

Acquisition of Businesses from UMass Memorial Medical Center

On January 2, 2013, the Company completed the acquisition of the clinical outreach and anatomic pathology businesses of UMass Memorial Medical Center ("UMass"). This purchase was the first step in a series of transactions between the parties whereby the two organizations expect to eventually have a financial stake in a new entity that will perform diagnostic information testing services in a defined territory within the state of Massachusetts. The assets acquired at the acquisition date primarily represent goodwill and intangible assets, principally comprised of customer-related intangibles (see Note 9). In addition the Company granted to UMass a call option and UMass granted to the Company a put option for UMass to acquire an 18.90% equity interest in a newly formed entity. The put and call options have a remaining vesting period of approximately 18 months (see Note 8).

Other Acquisitions

On May 15, 2013, the Company completed the acquisition of the toxicology and clinical laboratory business of Advanced Toxicology Network ("ATN") from Concentra, a subsidiary of Humana Inc. The assets acquired at the acquisition date primarily represent goodwill and intangible assets, principally comprised of customer-related intangibles (see Note 9).

On June 22, 2013, the Company completed the acquisition of certain lab-related clinical outreach service operations of Dignity Health ("Dignity"), a hospital system in California. The assets acquired at the acquisition date primarily represent goodwill and intangible assets, principally comprised of customer-related intangibles (see Note 9).
