21. | BUSINESS ACQUISITION
In the second quarter of 2022, the Company announced the signing of a definitive merger agreement to acquire 100% of the outstanding equity interest of Liberty for stock. Liberty was an Ohio bank holding company whose national bank subsidiary, Liberty National Bank, operated six offices in Central and Northwest Ohio. The transaction closed on December 1, 2022, with Liberty National Bank merging into Middlefield Bank, with Middlefield Bank as the surviving entity. The acquisition established the Company’s presence in Hardin, Logan, Franklin, and Union Counties. Under the terms of the merger agreement, Liberty shareholders received 2.752 shares of the Company’s common stock in exchange for each share of Liberty common stock they owned immediately before the merger. The Company issued 2.6 million shares of its common stock in the merger and the aggregate merger consideration was approximately $73.3 million. Upon closing, Liberty National Bank was merged into MBC, and its six full-service bank offices, in Ada and Kenton in Hardin County, in Bellefontaine and Bellefontaine South in Logan County, in Marysville in Union County, and in Westerville in Franklin County, became offices of MBC. The Company accounted for the Liberty acquisition using the acquisition method of accounting and accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair value on the acquisition date, in accordance with purchase accounting. The Company relied on the income approach to estimate the value of the loans. The loans’ underlying characteristics (account types, remaining terms (in months), annual interest rates or coupons, interest types, past delinquencies, timing of principal and interest payments, current market rates, loan-to-value ratios, loss exposures and remaining balance) were considered. Various assumptions were applied regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. Due to the timing of the merger, the estimated fair value measurements remain preliminary. Management will continue to review the estimated fair values and expects to finalize its analysis of the acquired assets and assumed liabilities in the transaction within one year of the merger. As the Company finalizes its analysis of these assets, there may be adjustments to the recorded carrying values. Any adjustments to carrying values will be recorded in goodwill. The calculation of goodwill is subject to change for up to one year after closing date of the transaction as additional information relative to closing date estimates and uncertainties becomes available. The Company also recorded an identifiable intangible asset representing the core deposit base of Liberty. The discounted cash flow method was used in valuing this intangible. This method is based upon the principle of future benefits; economic value is based on anticipated future benefits as measured by cash flows expected to occur in the future. The estimated future cash flows are converted to a value indicator by determining the present value of the cash flows using a discount rate. The discount rate is based upon the nature of the business, the level of risk, and the expected stability of the estimated future cash flows. The higher the risk, the higher the discount rate, and the lower the value indicator. Time deposit fair values were estimated using an income approach. The methodology entailed discounting the contractual cash flows of the instruments over their remaining contractual lives at prevailing market rates. Interest and principal payments were projected for each category of CDs over the period from the valuation date to the maturity dates. These payments represent future cash flows to be paid to depositors until maturity. Using appropriate market interest rates for each category of CDs, the future cash flows were discounted to their present value equivalents. The following table summarizes the purchase of Liberty as of December 1, 2022:

Middlefield recorded goodwill and intangibles associated with the purchase of Liberty totaling $16.7 million. Goodwill is not amortized, but is periodically evaluated for impairment. Middlefield Bank did not recognize any impairment during the year ended December 31, 2022. Identifiable intangibles are amortized to their estimated residual values over the expected useful lives. Such lives are also periodically reassessed to determine if any amortization period adjustments are required. During the year ended December 31, 2022, no such adjustments were recorded. The identifiable intangible assets consist of a core deposit intangible which is being amortized over the estimated useful life of 10 years. The gross carrying amount of the core deposit intangible acquired in the Liberty merger that closed in 2022 was $6.7 million at December 31, 2022 with $63,000 accumulated amortization as of that date. As of December 31, 2022, the current year and estimated future amortization expense for the core deposit intangible associated with this merger is as follows:
