On September 20, 2018, the Company, and Blue Hills Bancorp, Inc. (“Blue Hills Bancorp”), parent of Blue Hills Bank, signed a definitive merger agreement for the Company to acquire Blue Hills Bancorp and the Bank to acquire Blue Hills Bank. The merger agreement provides that each Blue Hills Bancorp stockholder will receive 0.2308 of a share of the Company's common stock and $5.25 in cash for each share of Blue Hills Bancorp common stock. The transaction is intended to qualify as a tax-free reorganization for federal income tax purposes and to provide a tax-free exchange for Blue Hills Bancorp stockholders for the Company common stock portion of the consideration they receive. The merger remains subject to regulatory approval and other customary closing conditions.

On November 16, 2018, the Company completed its acquisition of MNB Bancorp (MNB Bancorp), the parent company of The Milford National Bank and Trust Company. The transaction qualified as a tax-free reorganization for federal income tax purposes and MNB Bancorp shareholders received, for each share of MNB Bancorp common stock, the right to receive either $275 in cash per share or 3.55 shares of the Company's stock (valued at $285.38 per share, based upon the highest trading value of the Company's stock on November 16, 2018 of $80.39). The total deal consideration was $56.1 million and was comprised of 25% cash and 75% stock consideration, which equates to 528,353 shares of the Company's common stock issued to MNB Bancorp shareholders valued at $42.5 million, and $13.6 million in cash, inclusive of cash in lieu of fractional shares. In addition to increasing its loan, deposit and wealth management bases, the Company will be able to provide a deeper product set to new customers, as well as benefit from increased operating synergies, improving the long-term operating and financial results of the Company.

The Company accounted for the MNB Bancorp acquisition using the acquisition method pursuant to the Business Combinations Topic of the FASB ASC. Accordingly, the Company recorded merger and acquisition expenses of $8.8 million for the year ended December 31, 2018 related to the MNB Bancorp acquisition. Additionally, the acquisition method requires the acquirer to recognize the assets acquired and the liabilities assumed at their fair values as of the acquisition date. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed as of the date of the acquisition:



	Net Assets Acquired at Fair Value
	(Dollars in thousands)
Assets
Cash	$	6,743
Investments	25,358
Loans	293,498
Premises and equipment	1,904
Goodwill	24,299
Core deposit and other intangibles	8,588
Other assets	8,639
Total assets acquired	369,029
Liabilities
Deposits	278,204
Borrowings	33,093
Other liabilities	1,609
Total liabilities assumed	312,906
Purchase price	$	56,123

Fair value adjustments to assets acquired and liabilities assumed are generally amortized using either an effective yield or straight-line basis over periods consistent with the average life, useful life and/or contractual term of the related assets and liabilities.

The loans acquired were recorded at fair value without a carryover of the allowance for loan losses. Fair value of the loans is determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected, as adjusted for an estimate of future credit losses and prepayments, and then applying a market-based discount rate to those cash flows. The overall discount on the loans acquired in this transaction was due to anticipated credit loss, as well as considerations for liquidity and market interest rates. In addition, the acquired loans were reviewed to determine if any loans would be deemed purchased credit impaired, as determined by identifying evidence of deterioration of credit quality at the purchase date combined with an assumption that all contractually required payments will not be collected. No loans were deemed to be purchased credit impaired.

The fair value of the premises, including land, buildings and improvements, was determined based upon appraisals by licensed real estate appraisers. The appraisals were based upon the best and highest use of the property with final values determined based upon an analysis of the cost, sales comparison and income capitalization approaches for each property appraised.

The fair value of the core deposit intangible is derived by comparing the interest rate and servicing costs that the financial institution pays on the core deposit liability versus the current market rate for alternative sources of financing, while factoring in estimates over the remaining life and attrition rate of the deposit accounts. The intangible asset represents the stable and relatively low cost source of funds that the deposits and accompanying relationships provide the Company, when compared to alternative funding sources.

The fair value of acquired savings and transaction deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. The fair value of time deposits was determined based on the present value of the contractual cash flows over the remaining period to maturity using a market interest rate.

The loans acquired were recorded at fair value without a carryover of the allowance for loan losses. Fair value of the loans is determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected, as adjusted for an estimate of future credit losses and prepayments, and then applying a market-based discount rate to those cash flows. The overall discount on the loans acquired in this transaction was due to anticipated credit loss, as well as considerations for liquidity and market interest rates. In addition, the acquired loans were reviewed to determine if the loan had evidence of deterioration of credit quality at the purchase date and also reviewed to determine if it was probable that all contractually required payments will not be collected. Based on the review of the loan portfolio at the time of the acquisition, it was deemed that there was no evidence to show that any of the acquired loans were purchased credit impaired.

The fair value of acquired savings and transaction deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand.
