Item 8.01. Other Events.
As previously disclosed, on March 29, 2015, Catamaran Corporation (the "
Company
") entered into an Arrangement Agreement (the "
Arrangement Agreement
") with UnitedHealth Group Incorporated, a corporation incorporated under the laws of the State of Minnesota, USA ("
UnitedHealth Group
"), and 1031387 B.C. Unlimited Liability Company, an unlimited liability company incorporated under the laws of the Province of British Columbia, Canada, and a wholly owned subsidiary of UnitedHealth Group.
Completion of the statutory "arrangement" under Section 195 of the
Business Corporations Act
(Yukon) (the "
Arrangement
") is conditioned on, among other things, the expiration of the waiting period (and any extension thereof) or the granting of early termination under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "
HSR Act
").  The waiting period under the HSR Act expired on June 17, 2015.  The Company now anticipates that the Arrangement will be completed during the third quarter of 2015, but the Company cannot be certain when or if all the conditions to the Arrangement will be satisfied or, to the extent permitted, waived, including the approval by the Company's shareholders of a resolution approving the plan of arrangement contemplated by the Arrangement Agreement, the Arrangement Agreement and the Arrangement (or such other vote as a Yukon court may require).
