Notes to Unaudited Consolidated Financial Statements

The unaudited consolidated financial statements include the accounts of Cambridge Bancorp (the “Company”) and its wholly owned subsidiary, Cambridge Trust Company (the “Bank”), and the Bank’s wholly owned subsidiaries, Cambridge Trust Company of New Hampshire Inc., CTC Security Corporation, and CTC Security Corporation III. References to the Company herein relate to the consolidated group of companies. All significant intercompany accounts and transactions have been eliminated in preparation of the consolidated financial statements.

The Company is a state-chartered, federally registered bank holding company headquartered in Cambridge, Massachusetts and was incorporated in 1983. The Company is the sole shareholder of the Bank, a Massachusetts trust company chartered in 1890, which is a commercial bank.  We are a private bank offering a full range of private banking and wealth management services to our clients.  The private banking business, the Company’s only reportable operating segment, is managed as a single strategic unit.  

The unaudited consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) and disclosures necessary to present fairly the Company’s financial position, as of September 30, 2019 and December 31, 2018, respectively, and the results of operations and cash flows for the interim periods presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Interim results are not necessarily reflective of the results of the entire year.

For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses and the valuation of deferred tax assets are particularly subject to change.

Management has reviewed events occurring through November 7, 2019, the date the unaudited consolidated financial statements were available to be issued, and determined that no other subsequent events occurred requiring adjustment to or disclosure in these financial statements.

Accounting Standards Update 2018-16 - Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (“ASU 2018-16”). On October 25, 2018, the FASB issued ASU 2018-16 to introduce OIS Rate based on the SOFR as an acceptable US benchmark interest for the purpose of applying hedge accounting under Topic 815. This update is effective for interim and annual reporting periods beginning after December 15, 2018 because the Company has already adopted ASU 2017-12 - Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The Company adopted this update on January 1, 2019, and the update did not have a material impact on the consolidated financial statements.

Accounting Standards Update 2018-15 - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). On August 29, 2018, the FASB issued amended guidance to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years; early adoption is permitted and should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently assessing the impact the adoption of this guidance will have on our consolidated balance sheets, statements of income, and cash flows.

Accounting Standards Update 2018-14 - Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). On August 28, 2018, the FASB issued guidance to remove, add, and clarify certain disclosures for defined benefit plans. The ASU is effective for fiscal years ending after December 15, 2020; early adoption is permitted and should be applied using the retrospective method to all periods presented. We are currently assessing the impact the adoption of this guidance will have on our consolidated balance sheets, statements of income, and cash flows.  

Accounting Standards Update 2018-13 - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). On August 28, 2018, the FASB issued guidance to remove, add, and clarify certain disclosures for fair value measurement. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019; early adoption is permitted and should be applied using either retrospective method or the prospective method as specified in the ASU. We are currently assessing the impact the adoption of this guidance will have on our consolidated balance sheets, statements of income, and cash flows.

Accounting Standards Update 2018-07 - Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). On June 20, 2018, the FASB issued ASU 2018-07 to align the accounting for share-based payment awards issued to employees and nonemployees. The new guidance also clarifies that any share-based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers. Currently, the accounting for nonemployee share-based payments differs from that applied to employee awards, particularly with regard to the measurement date and the impact of performance conditions. Under the new guidance, the existing employee guidance will apply to nonemployee share-based transactions, with certain exceptions. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. The ASU is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year, and early adoption is permitted. The adoption of this guidance did not have a material impact on our consolidated balance sheets, statements of income, and cash flows.

Accounting Standard Update No. 2017-12 - Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). On August 28, 2017, the FASB issued a new standard that allows companies to better align their hedge accounting and risk management activities. The new standard will also reduce the cost and complexity of applying hedge accounting. The standard requires companies to change the recognition and presentation of the effects of hedge accounting by:

The standard also permits hedge accounting for strategies for which hedge accounting was not historically permitted and includes new alternatives for measuring the hedged item for fair value hedges of interest rate risk. Furthermore, the standard eases the requirements for effectiveness testing, hedge documentation, applying the critical terms match method, and introduces new alternatives that will permit companies to reduce the risk of material error corrections if they misapply the shortcut method. The new accounting standard was effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years.  

The new standard requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company early adopted the standard during the fourth quarter of 2018, using a modified retrospective transition method, and it did not have an effect on our consolidated balance sheets, statements of income, and cash flows. See note 18 – DERIVATIVE AND HEDGING ACTIVITIES.

Accounting Standards Update No. 2016-13 - Financial Instruments - Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). On June 16, 2016, the FASB issued ASU 2016-13, which will significantly change how entities measure and recognize credit impairment for many financial assets. Under this standard, the new current expected credit loss model will require entities to immediately recognize an estimate of credit losses expected to occur over the remaining life of the financial assets that are in the scope of the standard. This new guidance also made targeted amendments to the current impairment model for available for sale debt securities. This guidance will be effective for the Company for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption for fiscal years and interim periods beginning after December 15, 2018 is permitted. We are in the process of evaluating this guidance and its effect on our consolidated balance sheets, statements of income, and cash flows. We have developed an implementation plan which includes assessment of processes, portfolio segmentation, model development, system requirements, and the identification of data and resource needs to implement this standard. During the fourth quarter of 2019, the Company expects to perform a full parallel run of the current expected credit loss ("CECL") model alongside the current incurred loss model, using September 30, 2019 balances. In addition, the Company has also begun developing accounting policies, as well as considering the need for new internal controls relevant to the updated methodologies and models.

Accounting Standards Update No. 2016-02 - Leases (“ASU 2016-02”). On February 25, 2016, the FASB issued guidance that requires recognition of lease assets and lease liabilities on the statement of condition and disclosure of key information about leasing arrangements. In particular, this guidance requires a lessee of operating or finance leases to recognize on the statement of condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. Under previous GAAP, a lessee was not required to recognize lease assets and lease liabilities arising from operating leases on the statement of condition. The guidance became effective for the Company on January 1, 2019. Also in July 2018, the FASB issued Accounting Standards Update No. 2018-11, “Targeted Improvements” (“ASU 2018-11”), to allow an optional transition method in which the provisions of Topic 842 would be applied upon the adoption date and would not have to be retroactively applied to the earliest reporting period presented in the consolidated financial statements. Using the optional transition method discussed above, the Company adopted the new lease guidance on January 1, 2019 and recorded a right-of-use asset of $32.9 million and a corresponding net lease liability. See note 14 – LEASES.

Accounting Standards Update No. 2014-09 - Revenue from Contracts with Customers (“ASU 2014-09”). On May 28, 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new guidance supersedes current U.S. GAAP guidance on revenue recognition and requires the use of more estimates and judgments than the current revenue standards. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams, such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees, are also not in scope of the new guidance.

On January 1, 2018, the Company adopted ASU No. 2014-09 and all subsequent ASUs that modified Topic 606. Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, and merchant income. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, deposit related fees, and other income within noninterest income. Based on this assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company adopted ASU 2014-09 and its related amendments utilizing the modified retrospective approach. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Noninterest income considered in-scope of Topic 606 is discussed below.

Wealth Management and Trust Fees

The Company earns wealth management fees for providing investment management, trust administration, and financial planning services to clients. The Company’s performance obligation under these contracts is satisfied over time as the wealth management services are provided. Fees are recognized monthly based on the average monthly value of the assets under management and the applicable fee rate, or at a fixed annual rate, depending on the terms of the contract. No performance-based incentives are earned on wealth management contracts.

The Company earns trust fees for serving as trustee for certain clients. As trustee, the Company serves as a fiduciary, administers the client’s trust, and in some cases, manages the assets of the trust. The Company’s performance obligation under these agreements is satisfied over time as the administration and management services are provided. Fees are recognized monthly based on a percentage of the market value of the account or at a fixed annual rate as outlined in the agreement. The Company also earns fees for trust related activities. The Company’s performance obligation under these agreements is satisfied at a point in time and recognized when these services have been performed.

All of the wealth management and trust fee income on the consolidated statement of income is considered in-scope of Topic 606.

Other Banking Fee Income

The Company charges a variety of fees to its clients for services provided on the deposit and deposit management related accounts. Each fee is either transaction-based or assessed monthly. The types of fees include service charges on accounts, overdraft fees, wire transfer fees, maintenance fees, ATM fee charges, and other miscellaneous charges related to the accounts. These fees are not governed by individual contracts with clients. They are charges to clients based on disclosures presented to clients upon opening these accounts along with updated disclosures when changes are made to the fee structures. The transaction-based fees are recognized in revenue when charged to the client based on specific activity on the client’s account. Monthly service and maintenance charges are recognized in the month they are earned and are charged directly to the client’s account.

Optima Bank & Trust Company

The Company completed its merger with Optima Bank & Trust Company (“Optima”) on April 17, 2019. Under the terms of the Agreement and Plan of Merger (the “Merger Agreement”), each outstanding share of Optima common stock was converted into $32.00 in cash or 0.3468 shares of the Company’s common stock, with the transaction structured as 95 percent common stock and 5 percent cash.  As a result of the merger, former Optima shareholders received an aggregate of approximately 722,746 shares of the Company’s common stock and an aggregate of approximately $3.5 million in cash. The total consideration paid amounted to $64.3 million.

The Company accounted for the merger using the acquisition method pursuant to the Business Combinations Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). Accordingly, the Company recorded merger expenses during the three months and nine months ended September 30, 2019 of approximately $339,000 and $3.9 million, respectively. 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:

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.

Fair values of the major categories of assets acquired and liabilities assumed were determined as follows:

Cash and Cash Equivalents

The fair values of cash and cash equivalents approximate the respective carrying amounts because the instruments are payable on demand or have short-term maturities.

Investments

The fair values of securities were based on quoted market prices for identical securities received from an independent, nationally-recognized, third-party pricing service. Prices provided by the independent pricing service were based on recent trading activity and other observable information including, but not limited to, market interest rate curves, referenced credit spreads, and estimated prepayment rates where applicable.

Loans

The loans acquired were recorded at fair value without a carryover of the allowance for loan losses. Fair value of the loans portfolio 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.

Premises and Equipment

The fair value of the premises, including 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.

Core Deposit Intangible

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.

Deposits

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 were determined based on the present value of the contractual cash flows over the remaining period to maturity using a market interest rate.

Borrowings

Federal Home Loan Bank (“FHLB”) borrowings were recorded at their carrying value which approximates fair value.

At September 30, 2019 and December 31, 2018, cash and cash equivalents totaled $68.9 million and $18.5 million, respectively. Of this amount, $30.4 million and $12.7 million, respectively, were maintained to satisfy the reserve requirements of the Federal Reserve Bank of Boston (“FRB Boston”). Additionally, at September 30, 2019 and December 31, 2018, the Company pledged $500,000 to the New Hampshire Banking Department relating to Cambridge Trust Company of New Hampshire, Inc.’s operations in that state.

Investment securities have been classified in the unaudited consolidated balance sheets according to management’s intent. The carrying amounts of securities and their approximate fair values were as follows:

All of the Company’s mortgage-backed securities have been issued by, or are collateralized by securities issued by, either Government National Mortgage Association (Ginnie Mae), Federal National Mortgage Association (Fannie Mae), or Federal Home Loan Mortgage Corporation (Freddie Mac).
