Business acquisitions and development projects
(a)
Acquisition of Empire
Subsequent to year-end, on February 9, 2016, the Company entered into an agreement and plan of merger pursuant to which, a subsidiary of Liberty Utilities Co. will merge with and into The Empire District Electric Company and its subsidiaries (“Empire”), and Empire will survive the merger and become a wholly owned indirect subsidiary of the Company. Empire is a Joplin, Missouri based regulated electric, gas and water utility, serving customers in Missouri, Kansas, Oklahoma and Arkansas. 
Empire shareholders will receive U.S.$34.00 per common share in cash, which represents an aggregate purchase price of approximately $3,400,000 (U.S.$2,400,000), which includes the assumption of approximately $1,300,000 (U.S.$900,000) of debt.
The closing of the acquisition, which is expected to occur in early 2017, is subject to customary closing conditions, including the approval of Empire’s common shareholders, and the receipt of certain state and federal regulatory and government approvals.
On February 9, 2016, the Company obtained a $2,200,000 (U.S. $1,600,000) bridge financing commitment for the acquisition from a syndicate of banks (note 9).
On March 1, 2016, the Company issued $1,000,000 aggregate principal amount of 5.0% convertible unsecured subordinated debentures represented by instalment receipts (the “Debentures” or the “Debenture Offering”) and received the first instalment of $333,000. On March 9, 2016, the underwriters exercised their option to purchase $150,000 additional Debentures and received the first instalment of $49,950. The Debentures are expected to convert to common shares of the Company upon the closing of the acquisition of Empire (note 25).
(b)
Acquisition of Park Water System
Subsequent to year-end, on January 8, 2016, the Company completed the acquisition of Western Water Holdings, LLC which is the parent company of Park Water Company (“Park Water System”), a regulated water distribution utility. Park Water System owns and operates three regulated water utilities engaged in the production, treatment, storage, distribution, and sale of water in southern California and western Montana. The total purchase price for the Park Water System is U.S.$341,750, including debt assumed of U.S.$91,750 and is subject to certain closing adjustments. All costs related to the acquisition have been expensed through the consolidated statements of operations.
Due to the timing of the acquisition, the Company has not completed the fair value measurements of the assets acquired and liabilities assumed. The Company will continue to review information and perform further analysis prior to finalizing the fair value of the consideration paid and the fair value of the assets acquired and liabilities assumed.
Mountain Water Company is currently the subject of a condemnation proceeding by the city of Missoula. It is not known when the condemnation proceeding will conclude or whether the City of Missoula will ultimately take possession of Mountain Water Company. The City’s right to take Mountain Water Company is currently on appeal before the Montana Supreme Court, which is set to hear the appeal on April 22, 2016. If the City of Missoula prevails on appeal and ultimately takes possession of Mountain Water Company, the compensation to be paid by the City of Missoula for such taking will be the value of the utility plus accrued interest and attorney’s fees as determined by the Montana court.
