[1] | None of the cash held in escrow is considered contingent consideration as it is expected to be released to the Sellers pending the Sellers’ satisfaction of general representations and warranties made in connection with the execution of the purchase agreement.
[2] | Vinnolit’s long-term debt paid on behalf of the Sellers was not legally assumed by Westlake in the acquisition and was a condition of the consummation of the purchase agreement. Therefore, the retirement has been included in the total purchase consideration.
[3] | The fair value of accounts receivable acquired is $181,826, with the gross contractual amount being $183,769. The Company expects $1,943 to be uncollectible.
[4] | An adjustment of approximately $16,900 was recorded to reflect Vinnolit's inventories at fair value and increased cost of sales by the same amount for the three months ended September 30, 2014.
[5] | Included in other assets was a loan acquired that was repaid prior to September 30, 2014.
[6] | A liability arising from unfavorable forward purchase contracts for the purchase of power was recognized at fair value. This liability will be amortized over a period of approximately 3.0 years, being the weighted-average life of the forward purchase contracts.
[7] | Management estimated that the fair value of the net assets acquired equals consideration paid. Therefore, no goodwill was recorded.
