The fair values are estimates and are subject to adjustment for up to one year after the merger date. In the third quarter of 2017, the Company made a $1.1 million adjustment to deferred tax assets and the deal consideration. During the quarter ended June 30, 2018, the Company finalized its fair values with this acquisition.

The Company accounted for these transactions under the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition.

The loan portfolios of Plaza and HEOP were recorded at fair value at the date of each acquisition. A valuation of Plaza and HEOP's loan portfolio was performed as of the acquisition dates to assess the fair value of the loan portfolio. The loan portfolios were both segmented into two groups; loan with credit deterioration and loans without credit deterioration, and then split further by loan type. The fair value was calculated on an individual loan basis using a discounted cash flow analysis. The discount rate utilized was based on a weighted average cost of capital, considering the cost of equity and cost of debt. Also factored into the fair value estimates were loss rates, recovery period and prepayment rates based on industry standards.

The Company also determined the fair value of the core deposit intangible, securities and deposits with the assistance of third-party valuations as well as the fair value of other real estate owned ("OREO') was based on recent appraisals of the properties.

The core deposit intangible on non-maturing deposits was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates, service charge income, overhead expense and costs of alternative funding. Since the fair value of intangible assets are calculated as if they were stand-alone assets, the presumption is that a hypothetical buyer of the intangible asset would be able to take advantage of potential tax benefits resulting from the asset purchase. The value of the benefit is the present value over the period of the tax benefit, using the discount rate applicable to the asset.

In determining the fair value of certificates of deposit, a discounted cash flow analysis was used, which involved present valuing the contractual payments over the remaining life of the certificates of deposit at market-based interest rates.

For loans acquired from Plaza and HEOP, the contractual amounts due, expected cash flows to be collected, interest component and fair value as of the respective acquisition dates were as follows:



	Acquired Loans
	Plaza		HEOP
	(dollars in thousands)
Contractual amounts due	$	1,708,685	$	1,717,191
Cash flows not expected to be collected	20,152		4,442
Expected cash flows	1,688,533		1,712,749
Interest component of expected cash flows	625,592		348,100
Fair value of acquired loans	$	1,062,941	$	1,364,649

In accordance with U.S. GAAP, there was no carryover of the allowance for loan losses that had been previously recorded by Plaza and HEOP.
