Previously unvested CMYF restricted stock awards outstanding immediately prior to the close of the transaction vested and were considered issued and outstanding at acquisition close and included in consideration.

Northwest Bancorporation, Inc. On April 25, 2018, the Company entered into a definitive agreement to acquire all of the outstanding stock of Northwest Bancorporation, Inc. (“Northwest”), the parent company of Inland Northwest Bank (“INB”), a Spokane, Washington based community bank with 20 banking offices across Idaho, Oregon and Washington. The acquisition was completed on August 16, 2018, and the Company merged INB with its existing bank subsidiary, First Interstate Bank, on November 9, 2018.

Consideration for the acquisition was $176.3 million, consisting of the issuance of 3.84 million shares of the Company's Class A common stock valued at $45.15 per share, the closing price of the Company's Class A common stock as quoted on the NASDAQ stock market on the acquisition date. The Company paid approximately $3.0 million in cash related to Northwest warrants, which were included in the consideration paid. Holders of each share of Northwest common stock received 0.516 shares of First Interstate Class A common stock for each share of Northwest common stock. Additionally, all Northwest stock purchase warrants outstanding immediately prior to the close of the transaction were canceled in exchange for the right to receive a cash payment as provided in the Agreement. Previously unvested Northwest restricted stock awards outstanding immediately prior to the close of the transaction vested and were considered issued and outstanding at acquisition close.

The assets and liabilities of Northwest were provisionally recorded in the Company’s consolidated financial statements at their estimated fair values as of the acquisition date and will be finalized in the coming months. The excess value of the consideration paid over the fair value of assets acquired and liabilities assumed is recorded as provisional goodwill. The preliminary purchase price allocation resulted in provisional goodwill of $100.7 million, which is not deductible for income tax purposes. Goodwill resulting from the acquisition was allocated to the Company’s one operating segment, community banking, and consists largely of the synergies and economies of scale expected from combining the operations of Northwest and the Company.

The following table summarizes the consideration paid, fair values of the Northwest assets acquired and liabilities assumed, and the resulting goodwill. The amounts reported for net deferred tax assets and goodwill are provisional pending completion of the Company's review of tax items.

Explanation of fair value adjustments and the removal of previously recorded fair value marks recorded by Northwest. Note adjustments to the marks for deferred tax assets and premises and equipment were made since the prior quarter, none of which were material. The adjustments had no impact on 2018 earnings and a net decrease to goodwill of $0.4 million from the December 31, 2018 reported balances.
(1)	Write down of the book value of loans to their estimated fair values. The fair value of the loans was estimated using cash flow projections based on the remaining maturity and repricing terms, adjusted for estimated future credit losses and prepayments and discounted to present value using a risk-adjusted market rate for similar loans. The fair value of collateral dependent loans acquired with deteriorated credit quality was estimated based on the Company’s analysis of the fair value of each loan’s underlying collateral, discounted using market-derived rates of return with consideration given to the period of time and costs associated with foreclosure and disposition of the collateral.
(2)	Adjustment to remove the Northwest allowance for loan losses at acquisition date, as the credit risk is included in the fair value adjustment for loans receivable described in (1) above.
(3)	Adjustment represents the value of the core deposit base assumed in the acquisition based upon valuation from an independent accounting and advisory firm.
(4)	Adjustment consists of reductions to the fair value of other items, including the removal of Northwest previously recorded goodwill.
(5)	Increase in book value of time deposits to their estimated fair values based upon interest rates of similar time deposits with similar terms on the date of acquisition based upon valuation from an independent accounting and advisory firm.
(6)	Decrease due to the write-off of off balance sheet reserves.
(7)	Write down of the book value of debt to the estimated fair values on the date of acquisition based upon favorable interest rates in the market.
(8)	Adjustment consists of the write-off of pre-existing deferred tax assets and purchase accounting adjustments as a result of the acquisition.

Core deposit intangible assets of $15.7 million are being amortized using an accelerated method over the estimated useful lives of the related deposits of 10 years.

The Company acquired certain loans that are subject to Accounting Standards Codification ("ASC") Topic 310-30 "Loans and Debt Securities Acquired with Deteriorated Credit Quality." ASC Topic 310-30 provides recognition, measurement and disclosure guidance for acquired loans that have evidence of deterioration in credit quality since origination for which it is probable, at acquisition, the Company will be unable to collect all contractual amounts owed. For loans that meet the criteria stipulated in ASC Topic 310-30, the excess of all cash flows expected at acquisition over the initial fair value of the loans acquired ("accretable yield") is amortized to interest income over the expected remaining lives of the underlying loans using the effective interest method. The accretable yield will fluctuate due to changes in (i) estimated lives of underling credit-impaired loans, (ii) assumptions regarding future principal and interest amounts collected, and (iii) indices used to fair value variable rate loans.

Information regarding Northwest loans acquired deemed credit-impaired as of the August 16, 2018 acquisition date are as follows:



Contractually required principal and interest payments	$	27.5
Contractual cash flows not expected to be collected (“non-accretable discount”)	4.4
Cash flows expected to be collected	23.1
Interest component of cash flows expected to be collected (“accretable discount”)	3.2
Fair value of acquired credit-impaired loans	$	19.9

Information regarding Northwest acquired loans not deemed credit-impaired at the August 16, 2018 acquisition date are as follows:



Contractually required principal and interest payments	$	894.8
Contractual cash flows not expected to be collected	26.1
Fair value at acquisition	$	693.2

Unaudited pro forma consolidated revenues and net income as if the Northwest acquisition had occurred as of January 1, 2018, are not presented because the effect of this acquisition was not considered significant.
