Business Acquisition, Pro Forma Information, Description

The Company's historical financial information was adjusted to give effect to the pro forma events that were directly attributable to the Zohydro ER® acquisition and factually supportable. The unaudited pro forma consolidated results include historical revenues and expenses of assets acquired in the acquisition with the following adjustments:

• Adjustment to recognize incremental amortization expense based on the fair value of intangibles acquired;
• Adjustment to recognize incremental interest expense and amortization of debt issuance costs for debt issued in connection with the acquisition
• Eliminate transaction costs and non-recurring charges directly related to the acquisition that were included in the historical results of operations for Pernix
• Adjustment to recognize pro forma income tax based on income tax benefit on the amortization of intangible asset at the statutory tax rate of Ireland (12.50%), and the income tax benefit on the interest expense at the statutory tax rate of the United States (37.21%).

For the three months and six months ended June 30, 2015, the Company has recognized revenue and net loss for Zohydro ER® subsequent to the closing of April 24, 2015 in the amount of $4.0 million and $5.3 million respectively. Non-recurring transaction costs of $3.1 million related to the acquisition for the three months and six months ended June 30, 2015 are included in the condensed consolidated statement of operations in selling, general and administrative expenses; these non-recurring transaction costs have been excluded from the pro forma results in the above table.
