2017 Annual Report

An unwavering focus on 

results

for our customers, communities 
and shareholders. 

Chairman’s Message

Dear Fellow Shareholders & Customers: 

As we approach our 50th year, Century Bank’s unwavering focus on all aspects of the banking operation 
and ourselves is why we continue to produce results. We have positive results in our earnings, expense 
management, loan quality and customer satisfaction. 

I have never compromised on the most important part: Integrity – it counts. It counts with our customers. It 
counts with our communities. It counts with our shareholders and it counts with me. I learned from my father 
at an early age that if you were trusted by your customers, they would refer their friends and family to you. It’s 
an important lesson for business and in life. I have never forgotten that lesson and have instilled it with my 
children and all of the Century Bank Associates. 

According to Bloomberg®, I am the oldest active bank chairman in the world. I developed my finance skills 
while working in my father’s business selling furniture to families on installment. Those skills enabled my 
smooth transition into banking over 50 years ago. Here I am still at it - delivering results. 

I have many loyal customers, shareholders and associates. That continuity has been a driving force behind our 
continued good results. It’s why I come to work every day. I am an active part of the daily management of the 
bank as are many loyal associates whose tenure here exceeds 40 years. This is a rare trait in today’s financial 
industry. I attribute associate stability to our practice of developing competent personnel, enabling us to recruit 
internally for our future leaders. Rosalie Cunio, our first associate, still works beside me each day. 

The Bank’s Management Committee works cohesively to leverage a collaborative framework to develop 
technology strategy that achieves the bank’s objectives by empowering the customer and our workforce.

I’m thankful to be joined at the Bank with my son and daughter, Barry and Linda. They are highly educated, 
experienced and quite competent to lead Century Bank into the future. I am proud that Century Bank is the 
largest family-run bank in New England. I am humbled that we count among our customers some of the 
world’s most prestigious health care organizations, higher education institutions and Fortune 500 companies. 

Thank you for your support and I look forward to continuing to deliver results in 2018 and beyond.

Marshall M. Sloane
Founder and Chairman

President’s Message

Dear Fellow Shareholders:

2017 was a year of excellent core financial results, setting records for the 8th year in a row, until the President 
signed the Tax Cuts and Jobs Act of 2017 on December 22, 2017. Excluding the effects of the Tax Act, we had 
net earnings of over $30 million, and had growth of our capital to $269 million. Including the results of the Tax Act, 
net income for 2017 was $22.3 million and year-end capital was $260 million. 

While the reduction in corporate income taxes and the elimination of the corporate AMT (Alternative Minimum Tax) 
will have long-term benefits for Century, the short term consequence of the reduction in the corporate tax rate 
results in a revaluation of the Company’s net deferred tax assets (DTA’s). We have accumulated significant DTA’s 
over time, due in large measure to our unspent contributions to the loan loss reserve. When the tax rate is cut, 
in this case from 35% to 21%, as it was in December, the value of those DTA’s are proportionately reduced. For 
Century, the immediate write down to earnings and capital was $8.4 million. 

This outcome is predicated on a FASB rule, over which we have no control. It is a one-time event in 2017, and will 
have no impact on 2018 earnings. 

With all this so-called “noise,” we ended 2017 at $4.8 billion in assets, growth of 7.2%, and $22.3 million of 
annual earnings, a decline of 9.1%. Century earned $4.01 per share in 2017, as compared to $4.41 in 2016. 
Our stock rose an astounding 30% to $78.25 at year-end; a three-year cumulative total return of 99% and a 
five-year cumulative total return of 145%. All three principal business units again performed extremely well 
in 2017. 

Through up and down business and interest rate cycles of varying duration and severity, we have produced 
consistent and superior core results. We continued that trend in 2017. 

Our Family’s Bank. And Yours.

Our slogan translates into our devotion to treat our clients, as we, as a family and a business, would wish to be 
treated. It means fair products, rates, and fees, quick credit decisions and closings, transparency of process, and 
respect for the continuity and loyalty of our clients. Yet we also appreciate the frailty of life and business conditions, 
and try to support our clients through those inevitable undulations.

Let’s examine the multiple elements of Century’s results that have contributed to our success in 2017.

Results Through Centralized Hands on Management

Banking is a business of temperament and daily routine. We are steadfast in our centralized control and 
transparency of management. Our Loan Committee is a weekly institution that approves in open forum 
every loan over $500,000. So-called Deal of the Day meets almost every afternoon to approve all other 
loans and lines of credit. I participate in virtually every one. It is a level of centralized credit approval that
ensures we know the risks we take, makes sure we reward customer loyalty, and connects us to our clients 
and communities.

Our Management Committee is composed of the 11 most senior sector executives at Century. This bi-weekly, 
half-day, meeting follows an agenda that covers officer hirings, contracts, leases, audits, marketing campaigns, 
significant complaints, policy changes, donations, and pipelines of all new business. MANCOM, as we call it, 
sets our cultural tone of centralized, yet participatory, management engagement. Opinions and dialogue are 
encouraged; the wisdom of our collective executive team is shared. All have a stake in decisions made. 
It works. 

Results in Core Net Earnings Growth and Return on Equity

Net income declined by 9.1% to $22.3 million, or $4.01 per Class A share diluted, for the year ended 
December 31, 2017, as compared to net income of $24.5 million, or $4.41 per Class A share diluted for 
2016. Century’s return on average equity (ROE) was 8.75%, for 2017, as compared to 2016’s 10.80%. 
The ROE would have been 12.1%, had it not been for the DTA charge-off explained earlier. The ROE is the 
primary building block of our financial goal setting. It reflects our priority to grow shareholder value as the key 
driver of our strategic plan, our annual budget, and our tactical decisions. We can’t control the equity markets, 
but we can have a high level of confidence that if we continue to produce a core double digit ROE, the share 
price will follow over time. It is why we believe Standard and Poor’s/CFRA continues for the third year to rate 
Century’s shares an “A” and a “Buy.”

In addition, our efficiency ratio of overhead to revenue, the key comparative metric of non-interest expense 
decreased (favorable) from 63% in 2016 to 58% in 2017. We watch our expenses carefully, and are very 
proud of the efficiency ratio declining below 60%, an industry threshold target.

Results Yield Significant Asset Growth 

Total assets grew 7% to a record of $4.8 billion on December 31, 2017, up from 
$4.5 billion on December 31, 2016, an increase of $323 million. We experienced 
significant growth in 2017 for all three of our business lines: consumer, business, 
and institutional services. We are proud to have dozens of depositors who each 
routinely keep tens of millions at Century with confidence in our high performing 
earnings and asset growth. Being one of the 11 S&P/CFRA “A” rated banks in 
America, and one of only three in Massachusetts, is a strong external contributing 
confidence factor. 

Results Support Capital Adequacy 

Total equity was $260.3 million on December 31, 2017, an increase of $20.3 
million or 8.4% from $240.0 million on December 31, 2016. Book value per 
share increased to $46.75 at December 31, 2017, up by $3.64 from $43.11 
at December 31, 2016. Century is “well capitalized” by all regulatory standards, 
and we have passed all “Basel III” requirements through organic capital generation 
from earnings.

       Billion in Total Loans

Barry R. Sloane received the Living Legend Award from the Boston Renaissance Charter Public 
School honoring his work, in the tradition of Dr. Martin Luther King, Jr., for his exceptional service to 
their communities.

Results Grow Our Loan Portfolio

Our unique loan portfolio strategy continues to work exceptionally well. Total loans 
grew by $252 million or 13% to a record $2.18 billion on December 31, 2017; 
our largest loan portfolio ever, and a loan to deposit ratio of 56%. Non-performing 
assets continued to be a minimal number for a portfolio of our size, increasing 
from $1.1 million at December 31, 2016 to $1.7 million at December 31, 2017. 
The education and healthcare sectors anchor our loan growth, increasing 
some 13% as 2017 saw many quality not-for-profit institutions expanding and 
continuing to refinance debt with simpler and less expensive “direct purchase” 
loan placements. We are, by any standard, one of the leading experts in 
tax-exempt financing in New England.

We believe the magnetism and quality of Massachusetts’ colleges and universities 
validate our decade-long strategic conclusion that education and healthcare were, 
and are, the future of our region. 

Our calling officers are seeking new middle market business prospects every day. 
We combine expert market knowledge with extraordinary product expertise, 
leading to some of the longest duration satisfied relationships in commercial 
banking. The process goes on, every day, pushing up our market share, but it’s 
not easy as many of our peers have lower underwriting and pricing standards than 
we do. The middle business market is an exceptionally competitive environment. 

Loan quality is religion to us; our portfolio continues to be well diversified with 
emphasis on quality underwriting and effective ongoing monitoring of the loan 
portfolio.

2017 was a productive year in which we closed $90 million in residential first 
mortgages, and $165 million in home equity loans. We extended 198 energy 
conservation loans through the Mass Save loan program, which helped us do our 
part for conservation while originating many new long term relationships.

Results in Our Branch System

We are proud that five of our twenty-seven branches hold over $100 million in deposits, and total branch 
deposits exceed $1.8 billion. We are very discerning in the search for our next branch, #28. We are on
the lookout for further high visibility market-extending locations; small size and manageable cost is 
paramount. In addition, we now operate 50 ATMs, processing over 600,000 annual transactions.

We fully implemented in 2017 a regionally managed branch system, divided by geography, and 
placing supervision and mentoring much closer to the line. It worked skillfully in 2017 along 
with our superb staff, as branch deposits grew by 13%.

Results Fostered Record Growth in Institutional Services

The Institutional Services Group, which includes our government, cash management, and not-for-
profit banking teams, had another record year of client growth. Our share of government banking 
deposits is now the highest among Massachusetts chartered banks, and we have expanded our 
client set significantly in Rhode Island and New Hampshire.  

We processed over 34 million check and payment items in 2017, with exceptional quality control and 
customer service. The lockbox function remains a time tested magnet for corporate and institutional clients.
We are proud of the most stable operational management team in the industry, combining an advanced
technology platform with live and experienced customer service personnel. 

For the fifth consecutive year, the audit of our automated lockbox services and its operative effectiveness of 
controls was without any finding of deficiency.

In late 2017, we won the largest and most competitive corporate lockbox relationship in our history. 
This engagement will begin in 2018. Proof that our service, execution, and reputation is without peer in 
New England. We will do our utmost to insure it is always true.

Results in Wealth Management

2017 was the third full year of our wealth management function. Our assets 
under management grew 73.3% to over $126 million in 2017, and the business 
broke into positive earnings territory. Our wealth management business is a 
great opportunity to serve the generational transition challenges of our private 
clients while providing our non-profit clients an institutional-quality offering that 
embraces industry best practices. We specialize in global asset allocation 
“defensive” portfolios that we believe are particularly relevant when equity 
markets are near all time highs.

Results in Branding

It’s easy to be different in this realm as there is no other family managed and 
controlled bank of our size in New England. Our advertising, in print, radio, and 
now regional television, promotes our consistent message of local family control, 
permanence, approachability, and personal service. Dad, Linda, and I keep taking 
the time to personally sign each welcome note thanking all new clients of Century. 
This level of personal touch is unique from all others in the industry. 

Results in Information Systems

We pride ourselves on a technology platform of redundancy and expertise that our 
clients can rely on for financial inquiry, transactions, and high quality service. We 
are proud to say that Information Systems met all of its operational and service 
goals in 2017. We are constantly monitoring our systems reliability, and when 
customers encounter problems at night or on weekends, we’re always reachable.

We are forever vigilant in the daily battle against cybercrime. It is the new “bank 
robbery” risk. We employ the most sophisticated tools and consultants available 
to reduce our risks of fraud.

Results in Commitment to the Community

We are focused on our social responsibility to our home communities. Led by our 
imperative for locally controlled enterprise, community development, and relationship 
based philanthropy, we live our social mission every day. We support the Community 
Reinvestment Act function with staff, resources, and management commitment. We 
are proud that our most recent completed Massachusetts CRA audit was ranked a 
“High Satisfactory.” We diligently try to better serve our minority and lower income 
communities with home ownership opportunities and access to traditional banking 
services. We have refreshed our First Time Home Buyer offering, and are very proud 
that we are the lead lender to a new affordable housing project in Somerville of 
25 units to be occupied in 2018.

Results from our People and Our Values

We can’t say enough about the commitment and capability of our over 400 Century 
Associates. When bad weather, family calamity, or industry changes bring challenges, 
our colleagues faultlessly respond with time, ability and ingenuity. So many of our 
colleagues have worked together for decades, a rare condition in our industry that 
makes our teamwork superb. Most of the achievements described above are the 
result of the talent and resourcefulness of the Century team. 

Finally, we see so clearly our family and corporate values of industry, fairness, and 
community. The reduction in corporate tax rates were costly to our 2017 earnings. 
We are hopeful that the change will be a long-term benefit to both our profitability 
and economic activity. Early indications are quite positive for 2018.

Thank you to our shareholders, our clients, our associates, and our communities, for 
their confidence and relationships. We will endeavor to make 2018 another year of 
superior results through our diligence and resourcefulness.

Gratefully,

Barry R. Sloane

Century Bancorp, Inc.  AR ’17Financial HighlightsFORWARD-LOOKING STATEMENTS 

Certain statements contained herein are not based on historical facts and 
are “forward-looking statements” within the meaning of Section 21A of the 
Securities Exchange Act of 1934. Forward-looking statements, which are based 
on various assumptions (some of which are beyond the Company’s control), 
may be identified by reference to a future period or periods, or by the use 
of forward-looking terminology, such as “may,” “will,” “believe,” “expect,” 
“estimate,” “anticipate,” “continue” or similar terms or variations on those terms, 
or the negative of these terms. Actual results could differ materially from those 
set forth in forward-looking statements due to a variety of factors, including, 
but not limited to, those related to the economic environment, particularly 
in the market areas in which the Company operates, competitive products 
and pricing, fiscal and monetary policies of the U.S. Government, changes in 
government regulations affecting financial institutions, including regulatory fees 
and capital requirements, changes in prevailing interest rates, acquisitions and 
the integration of acquired businesses, credit risk management, asset/liability 
management, the financial and securities markets, and the availability of and 
costs associated with sources of liquidity. 

The Company does not undertake, and specifically disclaims any obligation, to 
publicly release the result of any revisions which may be made to any forward-
looking statements to reflect the occurrence of anticipated or unanticipated 
events or circumstances after the date of such statements. 

RECENT MARKET DEVELOPMENTS 

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection 
Act (the “Act”) became law. The Act was intended to address many issues arising 
in the recent financial crisis and is exceedingly broad in scope, affecting many 
aspects of bank and financial market regulation. The Act requires, or permits 
by implementing regulation, enhanced prudential standards for banks and bank 
holding companies inclusive of capital, leverage, liquidity, concentration and 
exposure measures. In addition, traditional bank regulatory principles such as 
restrictions on transactions with affiliates and insiders were enhanced. The Act 
also contains reforms of consumer mortgage lending practices and creates a 
Bureau of Consumer Financial Protection, which is granted broad authority 
over consumer financial practices of banks and others. It is expected as the 
specific new or incremental requirements applicable to the Company become 
effective that the costs and difficulties of remaining compliant with all such 
requirements will increase. The Act broadened the base for FDIC assessments 
to average consolidated assets less tangible equity of financial institutions and 
also permanently raises the current standard maximum FDIC deposit insurance 
amount to $250,000. The Act extended unlimited deposit insurance on non-
interest bearing transaction accounts through December 31, 2012. 

In addition, the Act added a new Section 13 to the Bank Holding Company 
Act, the so-called “Volcker Rule,” (the “Rule”) which generally restricts certain 
banking entities such as the Company and its subsidiaries or affiliates, from 
engaging in proprietary trading activities and owning equity in or sponsoring any 
private equity or hedge fund. The Rule became effective July 21, 2012. The final 
implementing regulations for the Rule were issued by various regulatory agencies 
in December, 2013 and under an extended conformance regulation compliance 
was required to be achieved by July 21, 2015. The conformance period for 
investments in and relationships with certain “legacy covered funds” has been 
extended to July 21, 2017. Under the Rule, the Company may be restricted 
from engaging in proprietary trading, investing in third party hedge or private 
equity funds or sponsoring new funds unless it qualifies for an exemption from 
the rule. The Company has little involvement in prohibited proprietary trading 
or investment activities in covered funds and the Company does not expect that 
complying with the requirements of the Rule will have any material effect on the 
Company’s financial condition or results of operation. 

Federal banking regulators have issued risk-based capital guidelines, which assign 
risk factors to asset categories and off-balance-sheet items. Also, the Basel 
Committee has issued capital standards entitled “Basel III: A global regulatory 
framework for more resilient banks and banking systems” (“Basel III”). The 
Federal Reserve Board has finalized its rule implementing the Basel III regulatory 
capital framework. The rule that came into effect in January 2015 sets the Basel 
III minimum regulatory capital requirements for all organizations. It included a 
new common equity Tier I ratio of 4.5 percent of risk-weighted assets, raised the 
minimum Tier I capital ratio from 4 percent to 6 percent of risk-weighted assets 
and would set a new conservation buffer of 2.5 percent of risk-weighted assets. 
The implementation of the framework did not have a material impact on the 
Company’s financial condition or results of operations. 

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was 
enacted, which represents the most comprehensive reform to the U.S. tax code 
in over thirty years. The majority of the provisions of the Tax Act takes effect on 
January 1, 2018. The Tax Act lowers the Company’s federal tax rate from 34% 
to 21%. Also, for tax years beginning after December 31, 2017, the corporate 
Alternative Minimum Tax (“AMT”) has been repealed. For 2018 through 2021, 
the AMT credit carryforward can offset regular tax liability and is refundable 
in an amount equal to 50% (100% for 2021) of the excess of the minimum 
tax credit for the tax year over the amount of the credit allowable for the year 
against regular tax liability. Accordingly, the full amount of the alternative 
minimum tax credit carryforward will be recovered in tax years beginning before 
2022. The Tax Act also contains other provisions that may affect the Company 
currently or in future years. Among these are changes to the deductibility of 
meals and entertainment, the deductibility of executive compensation, the 
dividend received deduction and net operating loss carryforwards. Tax Act 
changes for individuals include lower tax rates, mortgage interest and state 
and local tax limitations as well as an increase in the standard deduction, 
among others.

OVERVIEW 

Century Bancorp, Inc. (together with its bank subsidiary, unless the context 
otherwise requires, the “Company”) is a Massachusetts state-chartered bank 
holding company headquartered in Medford, Massachusetts. The Company is a 
Massachusetts corporation formed in 1972 and has one banking subsidiary (the 
“Bank”): Century Bank and Trust Company formed in 1969. At December 31, 
2017, the Company had total assets of $4.8 billion. Currently, the Company 
operates 27 banking offices in 20 cities and towns in Massachusetts, ranging 
from Braintree in the south to Andover in the north. The Bank’s customers 
consist primarily of small and medium-sized businesses and retail customers 
in these communities and surrounding areas, as well as local governments and 
large healthcare and higher education institutions throughout Massachusetts, 
New Hampshire, Rhode Island, Connecticut and New York. 

The Company’s results of operations are largely dependent on net interest 
income, which is the difference between the interest earned on loans and 
securities and interest paid on deposits and borrowings. The results of operations 
are also affected by the level of income and fees from loans, deposits, as well as 
operating expenses, the provision for loan losses, the impact of federal and state 
income taxes and the relative levels of interest rates and economic activity. 

The Company offers a wide range of services to commercial enterprises, state 
and local governments and agencies, non-profit organizations and individuals. It 
emphasizes service to small and medium sized businesses and retail customers in 
its market area. In recent years, the Company has increased business to larger 
institutions, specifically, healthcare and higher education. The Company makes 
commercial loans, real estate and construction loans and consumer loans, and 
accepts savings, time, and demand deposits. In addition, the Company offers its

Century Bancorp, Inc.  AR ’17Management’s Discussion and Analysis of Results of Operations and Financial Conditioncorporate and institutional customers automated lock box collection services, 
cash management services and account reconciliation services, and actively 
promotes the marketing of these services to the municipal market. Also, the 
Company provides full service securities brokerage services through a program 
called Investment Services at Century Bank, which is supported by LPL Financial, 
a third party full-service securities brokerage business. 

The Company has municipal cash management client engagements in 
Massachusetts, New Hampshire and Rhode Island comprised of approximately 
250 government entities. 

The Company had net income of $22,301,000 for the year ended 
December 31, 2017, compared with net income of $24,534,000 for the year 
ended December 31, 2016 and net income of $23,021,000 for the year ended 
December 31, 2015. Class A diluted earnings per share were $4.01 in 2017 
compared to $4.41 in 2016 and compared to $4.13 in 2015.

During 2017, the Company’s earnings were negatively impacted by a reduction 
in the value of its net deferred tax asset resulting in a charge of $8.4 million 
to income tax expense. This was the result of the enactment of the Tax Act on 
December 22, 2017, which lowered the Company’s federal tax rate from 34% 
to 21%. During 2017 and 2016, the Company’s earnings were positively 
impacted primarily by an increase in net interest income. This increase was 
primarily due to an increase in earning assets. Also contributing to the increase 
in earnings for 2016 was a decrease in the provision for loan losses. This was 
primarily the result of changes in the risk profile of the Company’s new loan 
originations, related methodology enhancements to address these changes, as 
well as net recoveries being realized during the year. During 2016 and 2015, 
the U.S. economy experienced a low short-term rate environment. The lower 
short-term rates negatively impacted the net interest margin as the rate at which 
short-term deposits could be invested declined more than the rates offered on 
those deposits.

During the second and third quarters of 2015 the net interest margin increased 
primarily as a result of an increase in higher yielding assets as well as prepayment 
penalties collected. The increase in higher yielding assets was primarily the result 
of increased purchases of securities held-to-maturity. The margin decreased 
during the fourth quarter of 2015 primarily as a result of lower yielding loan 
originations. The margin increased during the first quarter of 2016 primarily as a 

result of an increase in rates on earning assets. The margin decreased during the 
second, third, and fourth quarters of 2016 primarily as a result of a decrease in 
rates on earning assets. The margin increased during 2017 primarily as a result 
of an increase in rates on earning assets. This increase was primarily the result 
of the yield on floating rate assets increasing as a result of recent increases in 
short term interest rates as well as an increase in prepayment penalties collected 
during the second quarter of 2017. Prepayment penalties collected amounted 
to $825,000 and contributed approximately seven basis points to the net 
interest margin for the second quarter. During 2017, the Company has not 
seen a corresponding increase in short term rates on interest bearing liabilities. 
While management will continue its efforts to improve the net interest margin, 
there can be no assurance that certain factors beyond its control, such as the 
prepayment of loans and changes in market interest rates, will continue to 
positively impact the net interest margin.

U.S. Treasury Yield Curve 12/31/2015

A yield curve is a line that typically plots the interest rates of U.S. Treasury 
Debt, which have different maturity dates but the same credit quality, at a 
specific point in time. The three main types of yield curve shapes are normal, 
inverted and flat. Over the past three years, the U.S. economy has experienced 
low short-term rates. During 2016 and 2017, short-term rates increased more 
than longer-term rates resulting in a flattening of the yield curve. This flattening 
of the yield curve became more pronounced during 2017.

Total assets were $4,785,572,000 at December 31, 2017, an increase of 
7.2% from total assets of $4,462,608,000 at December 31, 2016.

On December 31, 2017, stockholders’ equity totaled $260,297,000, compared 
with $240,041,000 on December 31, 2016. Book value per share increased to 
$46.75 at December 31, 2017, from $43.11 on December 31, 2016.

During June 2016, the Company entered into a lease agreement to open a new 
branch located in Wellesley, Massachusetts. The Company closed its existing 
Wellesley branch and transferred the accounts to the new Wellesley branch 
which opened on December 19, 2016. On September 25, 2017 the Company 
purchased the new Wellesley location.

CRITICAL ACCOUNTING POLICIES 

Accounting policies involving significant judgments and assumptions by 
management, which have, or could have, a material impact on the carrying value 
of certain assets and impact income, are considered critical accounting policies. 

The Company considers allowance for loan losses and income taxes to be its 
critical accounting policies.

FINANCIAL CONDITION 

Investment Securities 

The Company’s securities portfolio consists of securities available-for-sale 
(“AFS”) and securities held-to-maturity (“HTM”). 

Securities available-for-sale consist of certain U.S. Treasury, U.S. Government 
Sponsored Enterprises, SBA Backed Securities, and U.S. Government Sponsored 
Enterprise mortgage-backed securities; state, county and municipal securities; 
privately issued mortgage-backed securities; other debt securities; and other 
marketable equities. 

These securities are carried at fair value, and unrealized gains and losses, 
net of applicable income taxes, are recognized as a separate component 
of stockholders’ equity. The fair value of securities available-for-sale at 
December 31, 2017 totaled $397,475,000 and included gross unrealized 
gains of $860,000 and gross unrealized losses of $948,000. A year earlier, 
the fair value of securities available-for-sale was $499,297,000 including gross 
unrealized gains of $555,000 and gross unrealized losses of $1,478,000. In 
2017, the Company recognized gains of $47,000 on the sale of available-for-
sale securities. In 2016 and 2015, the Company recognized gains of $52,000 
and $289,000, respectively. 

Securities classified as held-to-maturity consist of U.S. Government Sponsored 
Enterprises, SBA Backed Securities, and U.S. Government Sponsored Enterprise 
mortgage-backed securities. Securities held-to-maturity as of December 31, 
2017 are carried at their amortized cost of $1,701,233,000. A year earlier, 
securities held-to-maturity totaled $1,653,986,000. In 2017 the company did 
not recognize any gains on the sale of held-to-maturity securities. In 2016 and 
2015 the company recognized gains of $12,000 and $305,000, respectively, 
on the sale of held-to-maturity securities. The sales from securities held-to-
maturity relate to certain mortgage-backed securities for which the Company 
had previously collected a substantial portion of its principal investment. 

Allowance for Loan Losses 

Arriving at an appropriate level of allowance for loan losses necessarily involves 
a high degree of judgment. Management maintains an allowance for loan losses 
to absorb losses inherent in the loan portfolio. The allowance is based on 
assessments of the probable estimated losses inherent in the loan portfolio. 
Management’s methodology for assessing the appropriateness of the allowance 
consists of several key elements, which include the specific allowances, if 
appropriate, for identified problem loans, formula allowance, and possibly an 
unallocated allowance. Arriving at an appropriate level of allowance for loan 
losses necessarily involves a high degree of judgment. 

Specific allowances for loan losses entail the assignment of allowance amounts 
to individual loans on the basis of loan impairment. Under this method, loans are 
selected for evaluation based upon a change in internal risk rating, occurrence 
of delinquency, loan classification or nonaccrual status. The formula allowances 
are based on evaluations of homogenous loans to determine the allocation 
appropriate within each portfolio segment. Formula allowances are based on 
internal risk ratings or credit ratings from external sources. After considering 
the above components, an unallocated component may be generated to cover 
uncertainties that could affect management’s estimate of probable losses. 
Further information regarding the Company’s methodology for assessing the 
appropriateness of the allowance is contained within Note 1 of the “Notes to 
Consolidated Financial Statements”. 

During 2016 and 2017, the Company continued to enhance its methodology 
to the allowance for loan losses by updating qualitative factors on certain loan 
portfolios. Management believes that the allowance for loan losses is adequate. 
In addition, various regulatory agencies, as part of the examination process, 
periodically review the Company’s allowance for loan losses. Such agencies may 
require the Company to recognize additions to the allowance based on their 
judgments about information available to them at the time of their examination.

Income Taxes 

Certain areas of accounting for income taxes require management’s judgment, 
including determining the expected realization of deferred tax assets and the 
adequacy of liabilities for uncertain tax positions. Judgments are made regarding 
various tax positions, which are often subjective and involve assumptions 
about items that are inherently uncertain. If actual factors and conditions differ 
materially from estimates made by management, the actual realization of the net 
deferred tax assets or liabilities for uncertain tax positions could vary materially 
from the amounts previously recorded. 

Deferred tax assets arise from items that may be used as a tax deduction or 
credit in future income tax returns, for which a financial statement tax benefit 
has already been recognized. The realization of the net deferred tax asset 
generally depends upon future levels of taxable income. Valuation allowances are 
recorded against those deferred tax assets determined not likely to be realized. 
Deferred tax liabilities represent items that will require a future tax payment. 
They generally represent tax expense recognized in the Company’s financial 
statements for which payment has been deferred, or a deduction taken on the 
Company’s tax return but not yet recognized as an expense in the Company’s 
financial statements. Deferred tax liabilities are also recognized for certain non-
cash items such as goodwill.

The majority of the Company’s securities AFS are classified as Level 2, as defined in Note 1 of the “Notes to Consolidated Financial Statements.” The fair values of 
these securities are obtained from a pricing service, which provides the Company with a description of the inputs generally utilized for each type of security. These 
inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. 
Management’s understanding of a pricing service’s pricing methodologies includes obtaining an understanding of the valuation risks, assessing its qualification, 
verification of sources of information and processes used to develop prices and identifying, documenting, and testing controls. Management’s validation of a vendor’s 
pricing methodology includes establishing internal controls to determine that the pricing information received by a pricing service and used by management in the 
valuation process is relevant and reliable. Market indicators and industry and economic events are also monitored. The decline in fair value from amortized cost for 
individual available-for-sale securities that are temporarily impaired is not attributable to changes in credit quality. Because the Company does not intend to sell any of 
its debt securities and it is not more likely than not that it will be required to sell the debt securities before the anticipated recovery of their remaining amortized cost, 
the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2017. 

The increase in SBA Backed Securities was primarily the result of an increased investment return combined with a lower risk rating in these types of securities. The 
decrease in Obligations Issued by States and Political Subdivisions was primarily the result of increased competition in the bidding process for these types of securities.

Securities available-for-sale totaling $82,600,000, or 1.7% of assets, are classified as Level 3, as defined in Note 1 of the “Notes to Consolidated Financial 
Statements.” These securities are generally municipal securities with no readily determinable fair value. The Company also utilizes internal pricing analysis on various 
municipal securities using market rates on comparable securities. The securities are carried at fair value with periodic review of underlying financial statements and 
credit ratings to assess the appropriateness of these valuations. 

Debt securities of Government Sponsored Enterprises refer primarily to debt securities of Fannie Mae and Freddie Mac.

At December 31, 2017 and 2016, the Bank had no investments in obligations of individual states, counties, municipalities or nongovernment corporate entities which 
exceeded 10% of stockholders’ equity. In 2017, sales of securities totaling $18,180,000 in gross proceeds resulted in a net realized gain of $47,000. In 2016, sales 
of securities totaling $2,568,000 in gross proceeds resulted in a net realized gain of $64,000. There were no sales of state, county or municipal securities during 
2017 and 2016.

Management reviews the investment portfolio for other-than-temporary impairment of individual securities on a regular basis. The results of such analysis are 
dependent upon general market conditions and specific conditions related to the issuers of our securities. 

Loans 

The Company’s lending activities are conducted principally in Massachusetts, New Hampshire, Rhode Island, Connecticut and New York. The Company grants single-
family and multi-family residential loans, commercial and commercial real estate loans, municipal loans, and a variety of consumer loans. To a lesser extent, the Company 
grants loans for the construction of residential homes, multi-family properties, commercial real estate properties and land development. Most loans granted by the 
Company are secured by real estate collateral. The ability and willingness of commercial real estate, commercial, construction, residential and consumer loan borrowers 
December 31, 
to honor their repayment commitments are generally dependent on the health of the real estate market in the borrowers’ geographic areas and of the general economy.

The Company’s commercial and industrial (“C&I”) loan customers represent various small and middle-market established businesses involved in manufacturing, distribution, 
retailing and services. Most clients are privately owned with markets that range from local to national in scope. Many of the loans to this segment are secured by liens on 
corporate assets and the personal guarantees of the principals. The regional economic strength or weakness impacts the relative risks in this loan category. There is little 
concentration in any one business sector, and loan risks are generally diversified among many borrowers. 

C&I loan customers also include large healthcare and higher education institutions. During 2016 and 2017, the Company increased its lending activities to these 
types of organizations. This increase may expose the Company to concentration risks inherent in financings based upon analysis of credit risk, the value of underlying 
collateral, and other more intangible factors, which are considered in originating commercial loans. The percentage of these types of organizations to total C&I loans has 
increased to 87 % at December 31, 2017, compared to 81% at December 31, 2016.

Commercial real estate loans are extended to finance various manufacturing, warehouse, light industrial, office, retail and residential properties in the Bank’s market 
area, which generally includes Massachusetts, New Hampshire, and Rhode Island. Also included are loans to educational institutions, hospitals and other non-profit 
organizations. Loans are normally extended in amounts up to a maximum of 80% of appraised value and normally for terms between three and thirty years. 

Amortization schedules are long term and thus a balloon payment is generally due at maturity. Under most circumstances, the Bank will offer to rewrite or otherwise extend 
the loan at prevailing interest rates. During recent years, the Bank has emphasized nonresidential-type owner-occupied properties. This complements our C&I emphasis 
placed on the operating business entities and will continue. The regional economic environment affects the risk of both nonresidential and residential mortgages. 

Municipal loans customers include loans to municipalities or related interests, primarily for infrastructure projects. The Company had increased its lending activities 
to municipalities through 2016. Municipal loans decreased during 2017 as a result of loan payoffs. 

Residential real estate (1–4 family) includes two categories of loans. Included in residential real estate are approximately $33,835,000 of C&I type loans secured by 
1–4 family real estate. Primarily, these are small businesses with modest capital or shorter operating histories where the collateral mitigates some risk. This category of 
loans shares similar risk characteristics with the C&I loans, notwithstanding the collateral position. 

The other category of residential real estate loans is mostly 1–4 family residential properties located in the Bank’s market area. General underwriting criteria are largely the 
same as those used by Fannie Mae. The Bank utilizes mortgage insurance to provide lower down payment products and has provided a “First Time Homebuyer” product 
to encourage new home ownership. Residential real estate loan volume has increased and remains a core consumer product. The economic environment impacts the risks 
associated with this category. 

Home equity loans are extended as both first and second mortgages on owner-occupied residential properties in the Bank’s market area. Loans are underwritten to a 
maximum loan to property value of 75%. 

Bank officers evaluate the feasibility of construction projects based on independent appraisals of the project, architects’ or engineers’ evaluations of the cost 
of construction and other relevant data. As of December 31, 2017, the Company was obligated to advance a total of $15,152,000 to complete projects 
under construction.

At December 31, 2017, 2016, 2015, 2014 and 2013 impaired loans had specific reserves of $164,000, $173,000, $250,000, $904,000 and $1,019,000, 
respectively. 

The Company was servicing mortgage loans sold to others without recourse of approximately $229,533,000, $229,730,000, $185,299,000, $143,696,000 and 
$109,301,000 at December 31, 2017, 2016, 2015, 2014 and 2013, respectively. The Company had no loans held for sale at December 31, 2017, December 31, 
2016, December 31, 2015, December 31, 2014 and December 31, 2013.

Servicing assets are recorded at fair value and recognized as separate assets when rights are acquired through sale of loans with servicing rights retained. Mortgage 
servicing assets (“MSA”) are amortized into non-interest income in proportion to, and over the period of, the estimated net servicing income. Upon sale, the mortgage 
servicing asset is established, which represents the then-current estimated fair value based on market prices for comparable mortgage servicing contracts, when 
available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates 
assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, an inflation rate, ancillary 
income, prepayment speeds and default rates and losses. Servicing rights are assessed for impairment based on fair value at each reporting date. MSAs are reported 
in other assets in the consolidated balance sheets. MSAs totaled $1,525,000 at December 31, 2017, $1,629,000 at December 31, 2016, $1,305,000 at 
December 31, 2015, $941,000 at December 31, 2014 and $703,000 for December 31, 2013.

Directors and officers of the Company and their associates are customers of, and have other transactions with, the Company in the normal course of business. All loans 
and commitments included in such transactions were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for 
comparable transactions with other persons and do not involve more than normal risk of collection or present other unfavorable features. 

Loans are placed on nonaccrual status when any payment of principal and/or interest is 90 days or more past due, unless the collateral is sufficient to cover both 
principal and interest and the loan is in the process of collection. The Company monitors closely the performance of its loan portfolio. In addition to internal 
loan review, the Company has contracted with an independent organization to review the Company’s commercial and commercial real estate loan portfolios. This 
independent review was performed in each of the past five years. The status of delinquent loans, as well as situations identified as potential problems, is reviewed on a 
regular basis by senior management and monthly by the Board of Directors of the Bank. 

Nonaccrual loans increased during 2017, primarily as a result of an increase in home equity and residential real estate nonperforming loans. Nonaccrual loans 
decreased during 2016, primarily as a result of a decrease in home equity and residential real estate nonperforming loans. Nonaccrual loans decreased during 2015 
primarily due to the sale and partial charge-off of the property securing a large commercial real estate loan subsequent to foreclosure. Nonaccrual loans increased 
during 2014 primarily as a result of a large commercial real estate loan. 

The Company continues to monitor closely $37,184,000 and $35,583,000 at December 31, 2017 and 2016, respectively, of loans for which management has 
concerns regarding the ability of the borrowers to perform. The majority of the loans are secured by real estate and are considered to have adequate collateral value to 
cover the loan balances at December 31, 2017, although such values may fluctuate with changes in the economy and the real estate market. The increase is primarily 
attributable to one loan relationship secured by real estate. 

Allowance for Loan Losses 

The Company maintains an allowance for loan losses in an amount determined by management on the basis of the character of the loans, loan performance, financial 
Year Ended December 31, 
condition of borrowers, the value of collateral securing loans and other relevant factors. The following table summarizes the changes in the Company’s allowance for

The amount of the allowance for loan losses results from management’s evaluation of the quality of the loan portfolio considering such factors as loan status, specific 
reserves on impaired loans, collateral values, financial condition of the borrower, the state of the economy and other relevant information. The pace of the charge-offs 
depends on many factors, including the national and regional economy. Cyclical lagging factors may result in charge-offs being higher than historical levels. Charge-offs 
declined in 2014, 2015 and 2016 as a result of the overall decrease in the level of nonaccrual loans. The dollar amount of the allowance for loan losses increased primarily 
as a result of an increase in loan balances offset, somewhat, by lower historical loss factors. 

During 2015, the Company enhanced its approach to the development of the historical loss factors and qualitative factors used on certain loan portfolios. The 
methodology enhancement was in response to the changes in the risk characteristics of the Company’s new loan originations, as the Company has continued to 
increase its exposure to larger loan originations to large institutions with strong credit quality. The Company has limited internal loss history experience with these

types of loans, and has determined a more appropriate representation of loss expectation is to utilize external historical loss factors based on public credit ratings, 
as there is a great deal of default and loss data available on these types of loans from the credit rating agencies. As of June 30, 2015, the Company incorporated 
this information into the development of the historical loss rates for these loan types. The combination of the enhancements made to the allowance methodology to 
address the changing risk profile of the Company’s new loan originations and the increase in these loan types as a percentage of the overall portfolio, has resulted 
in a decrease in the ratio of allowance for loan losses to total loans for 2015. For 2016 and 2017, the change in the ratio of the allowance for loan losses to loans 
outstanding, was primarily due to changes in portfolio composition, lower historical loss rates, and qualitative factor adjustments. 

In addition, the Company monitors the outlook for the industries in which these institutions operate. Healthcare and higher education are the primary industries. The 
Company also monitors the volatility of the losses within the historical data. 

By combining the credit rating, the industry outlook and the loss volatility, the Company arrives at the quantitative loss factor for each credit grade.

The allowance for loan losses is an estimate of the amount needed for an adequate reserve to absorb losses in the existing loan portfolio. This amount is determined by 
an evaluation of the loan portfolio, including input from an independent organization engaged to review selected larger loans, a review of loan experience and current 
2016 
economic conditions. Although the allowance is allocated between categories, the entire allowance is available to absorb losses attributable to all loan categories. At 
December 31 of each year listed below, the allowance is comprised of the following:

Management believes that the allowance for loan losses is adequate. In addition, various regulatory agencies, as part of the examination process, periodically review 
the Company’s allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance based on their judgments about information 
available to them at the time of their examination. The enhancements described above have resulted in a lower level of unallocated allowance for loan losses. Further 
information regarding the allocation of the allowance is contained within Note 6 of the “Notes to Consolidated Financial Statements.”

The Company offers savings accounts, NOW accounts, demand deposits, time deposits and money market accounts. Additionally, the Company offers cash 
management accounts which provide either automatic transfer of funds above a specified level from the customer’s checking account to a money market account or 
short-term borrowings. Also, an account reconciliation service is offered whereby the Company provides a report balancing the customer’s checking account. 

Interest rates on deposits are set twice per month by the Bank’s rate-setting committee, based on factors including loan demand, maturities and a review of competing 
interest rates offered. Interest rate policies are reviewed periodically by the Executive Management Committee.

Borrowings 

The Bank’s borrowings consisted primarily of Federal Home Loan Bank of Boston (“FHLBB”) borrowings collateralized by a blanket pledge agreement on the Bank’s 
FHLBB stock, certain qualified investment securities, deposits at the FHLBB and residential mortgages held in the Bank’s portfolios. The Bank’s borrowings from the 
FHLBB totaled $347,778,000, an increase of $54,778,000 from the prior year. The Bank’s remaining term borrowing capacity at the FHLBB at December 31, 2017, 
was approximately $127,631,000. In addition, the Bank has a $14,500,000 line of credit with the FHLBB. See Note 12, “Other Borrowed Funds and Subordinated 
Debentures,” for a schedule, including related interest rates and other information. 

Subordinated Debentures 

In December 2004, the Company consummated the sale of a Trust Preferred Securities offering, in which it issued $36,083,000 of subordinated debt securities due 
2034 to its newly formed unconsolidated subsidiary, Century Bancorp Capital Trust II. 

Century Bancorp Capital Trust II then issued 35,000 shares of Cumulative Trust Preferred Securities with a liquidation value of $1,000 per share. These securities 
paid dividends at an annualized rate of 6.65% for the first ten years and then converted to the three-month LIBOR rate plus 1.87% for the remaining 20 years. The 
coupon rate on these securities was 3.46% at December 31, 2017. The Company is using the proceeds primarily for general business purposes. 

Securities Sold Under Agreements to Repurchase 

The Bank’s remaining borrowings consist primarily of securities sold under agreements to repurchase. Securities sold under agreements to repurchase totaled 
$158,990,000, a decrease of $23,290,000 from the prior year. See Note 11, “Securities Sold Under Agreements to Repurchase,” for a schedule, including related 
interest rates and other information. 

RESULTS OF OPERATIONS 

Net Interest Income 

The Company’s operating results depend primarily on net interest income and fees received for providing services. Net interest income on a fully taxable equivalent 
basis increased 14.5% in 2017 to $99,595,000, compared with $86,999,000 in 2016. The increase in net interest income for 2017 was mainly due to an 8.1% 
increase in the average balances of earning assets, combined with a similar increase in deposits. The increase in net interest income for 2016 was mainly due to a 
10.3% increase in the average balances of earning assets, combined with a similar increase in deposits. The level of interest rates, the ability of the Company’s earning 
assets and liabilities to adjust to changes in interest rates and the mix of the Company’s earning assets and liabilities affect net interest income. The net interest margin 
on a fully taxable equivalent basis increased to 2.25 % in 2017 and decreased to 2.12% in 2016 from 2.18% in 2015. The increase in the net interest margin for 
2017 was primarily attributable to an increase in rates on earning assets and prepayment penalties collected. The decrease in the net interest margin, for 2016, 
was primarily the result of a decrease in rates on earning assets. This is primarily as a result of originating larger loans to borrowers with high credit quality, some of 
which are at variable rates. The Company collected approximately $907,000, $416,000 and $945,000, respectively, of prepayment penalties, which are included in 
interest income on loans, for 2017, 2016 and 2015, respectively. 

Additional information about the net interest margin is contained in the “Overview” section of this report. Also, there can be no assurance that certain factors beyond 
its control, such as the prepayment of loans and changes in market interest rates, will continue to positively impact the net interest margin. Management believes 
that the current yield curve environment will continue to present challenges as deposit and borrowing costs may have the potential to increase at a faster rate than 
corresponding asset categories.

Average earning assets were $4,435,905,000 in 2017, an increase of $330,744,000 or 8.1% from the average in 2016, which was 10.3% higher than the 
average in 2015. Total average securities, including securities available-for-sale and securities held-to-maturity, were $2,186,915,000, an increase of 7.6% from 
the average in 2016. The increase in securities volume was mainly attributable to an increase in taxable securities held-to-maturity. An increase in securities volume 
and short term rates resulted in higher securities income, which increased 20.2% to $45,795,000 on a fully tax equivalent basis. Total average loans increased 
12.1% to $2,059,797,000 after increasing $330,590,000 in 2016. The primary reason for the increase in loans was due in large part to an increase in tax-exempt 
lending as well as taxable residential mortgage and commercial lending. The increase in loan volume resulted in higher loan income. Loan income increased by 13.2% 
or $9,256,000 to $79,523,000 in 2017 compared to 2016. Total loan income was $62,998,000 in 2015. Prepayment penalties collected were $907,000, 
$416,000, and $945,000 for 2017, 2016, and 2015, respectively. 

The Company’s sources of funds include deposits and borrowed funds. On average, deposits increased 11.4%, or $391,898,000, in 2017 after increasing by 13.5%, 
or $408,321,000, in 2016. Deposits increased in 2017, primarily as a result of increases in time deposits, savings, demand deposits, money market, and NOW 
accounts. Deposits increased in 2016, primarily as a result of increases in demand deposits, savings, money market, NOW accounts, and time deposits. Borrowed funds 
and subordinated debentures decreased by 14.1% in 2017, following a decrease of 6.2% in 2016. The majority of the Company’s borrowed funds are borrowings 
from the FHLBB and retail repurchase agreements. Average borrowings from the FHLBB decreased by approximately $48,872,000, and average retail repurchase 
agreements decreased by $33,272,000 in 2017. Interest expense totaled $27,820,000 in 2017, an increase of $5,203,000, or 23.0%, from 2016 when interest 
expense increased 12.3% from 2015. The increase in interest expense, for 2017, is primarily due to increases in the rates on deposits as well as an increase in average 
balances of deposits offset, somewhat, by a decrease in borrowed funds. The increase in interest expense, for 2016, is primarily due to increases in the average 
balances of deposits as well as an increase in rates offset, somewhat, by a decrease in borrowed funds.

Provision for Loan Losses 

The provision for loan losses was $1,790,000 in 2017, compared with 
$1,375,000 in 2016 and $200,000 in 2015. These provisions are the result 
of management’s evaluation of the amounts and credit quality of the loan 
portfolio considering such factors as loan status, collateral values, financial 
condition of the borrower, the state of the economy and other relevant 
information. The provision for loan losses increased during 2017, primarily as a 
result of an increase in loan balances offset, somewhat, by changes in historical 
loss factors. The provision for loan losses increased during 2016, primarily as 
a result of an increase in loan balances. During the second quarter of 2015, 
the Company enhanced its approach to the development of the historical loss 
factors on certain loans within the portfolio. This was done in response to 
the changing risk profile of the Company’s new loan originations and related 
methodology enhancements to address these changes. 

Other Operating Income 

During 2017, the Company continued to experience strong results in its fee-
based services, including fees derived from traditional banking activities such as 
deposit-related services, its automated lockbox collection system and full-
service securities brokerage supported by LPL Financial, a full-service securities 
brokerage business. 

Under the lockbox program, which is not tied to extensions of credit by the 
Company, the Company’s customers arrange for payments of their accounts 
receivable to be made directly to the Company. The Company records the 
amounts paid to its customers, deposits the funds to the customer’s account 
and provides automated records of the transactions to customers. Typical 
customers for the lockbox service are municipalities that use it to automate tax 
collections, cable TV companies and other commercial enterprises. 

Through a program called Investment Services at Century Bank, the Bank 
provides full-service securities brokerage services supported by LPL Financial, a 
full-service securities brokerage business. Registered representatives employed 
by Century Bank offer limited investment advice, execute transactions and 
assist customers in financial and retirement planning. LPL Financial provides 
research to the Bank’s representatives. The Bank receives a share in the 
commission revenues. 

Total other operating income in 2017 was $16,552,000, an increase of 
$330,000, or 2.0%, compared to 2016. This increase followed an increase 
of $229,000, or 1.4%, in 2016, compared to 2015. Included in other 
operating income are net gains on sales of securities of $47,000, $64,000 
and $594,000 in 2017, 2016 and 2015, respectively. Also included in other 
operating income are net gains on sales of mortgage loans of $370,000, 
$1,331,000 and $1,034,000 in 2017, 2016 and 2015, respectively. Service 
charge income, which continues to be a major source of other operating income, 
totaling $8,586,000 in 2017, increased $679,000 compared to 2016. This 
followed an increase of $175,000 in 2016 compared to 2015. The increase 
in fees, in 2017, was mainly attributable to an increase in fees collected from 
processing activities and debit card fees. The increase in fees, in 2016, was 
mainly attributable to an increase in fees collected from processing activities 
and debit card fees; this was offset somewhat by a decrease in overdraft fees. 
Lockbox revenues totaled $3,290,000, up $126,000 in 2017 following 

a decrease of $47,000 in 2016. Other income totaled $3,906,000, up 
$465,000 in 2017 following an increase of $399,000 in 2016. The increase 
in 2017 was primarily the result of increases in wealth management fees, and 
merchant card sales royalties. The increase in 2016 was primarily the result of 
increases in wealth management fees, merchant and charge card sales royalties, 
and cash surrender values of life insurance policies. 

Operating Expenses 

Total operating expenses were $67,119,000 in 2017, compared to 
$64,757,000 in 2016 and $62,198,000 in 2015. 

Salaries and employee benefits expenses increased by $1,865,000 or 4.7% 
in 2017, after increasing by 3.8% in 2016. The increase in 2017 was mainly 
attributable to merit increases in salaries, bonus, and health insurance costs. The 
increase in 2016 was mainly attributable to merit increases in salaries, bonus 
accruals, pension costs and health insurance costs. 

Occupancy expense decreased by $7,000, or 0.1%, in 2017, following an 
increase of $31,000, or 0.5%, in 2016. The decrease in 2017 was primarily 
attributable to a decrease in rent expense. The increase in 2016 was primarily 
attributable to an increase in rent expense. 

Equipment expense increased by $47,000, or 1.7%, in 2017, following an 
increase of $219,000, or 8.3%, in 2016. The increase in 2017 was primarily 
attributable to an increase in service contracts. The increase in 2016 was 
primarily attributable to an increase in depreciation expense. 

FDIC assessments decreased by $321,000, or 16.9%, in 2017, following a 
decrease of $250,000, or 11.6%, in 2016. FDIC assessments decreased in 
2017 and 2016 mainly as a result of a decrease in the assessment rate. 

Other operating expenses increased by $778,000 in 2017, which followed a 
$1,107,000 increase in 2016. The increase in 2017 was primarily attributable 
to an increase in contributions, legal expenses, and marketing expenses. 
The increase in 2016 was primarily attributable to an increase in marketing 
expenses, telephone expenses, software maintenance costs, contributions, and 
postage expenses. 

Provision for Income Taxes 

Income tax expense was 10,958,000 in 2017, $(362,000) in 2016, and 
$533,000 in 2015. The effective tax rate was 32.9% in 2017, (1.5%) in 
2016 and 2.3% in 2015. The increase in the effective tax rate for 2017 was 
primarily the result of a reduction in the value of the deferred tax asset resulting 
in a charge of $8,448,000 to income tax expense. On December 22, 2017, the 
Tax Act was enacted, which lowered the Company’s federal tax rate from 34% 
to 21%. As a result of the rate reduction, the Company recorded a reduction in 
the value of its net deferred tax asset. The decrease in the effective tax rate for 
2016 was mainly attributable to an increase in tax-exempt interest income as 
a percentage of taxable income. The federal tax rate was 34% in 2017, 2016 
and 2015.

Liquidity and Capital Resources 

Market risk is the risk of loss from adverse changes in market prices and rates. 
The Company’s market risk arises primarily from interest rate risk inherent in its 
lending and deposit-taking activities. To that end, management actively monitors 
and manages its interest rate risk exposure. 

The Company’s profitability is affected by fluctuations in interest rates. A 
sudden and substantial change in interest rates may adversely impact the 
Company’s earnings to the extent that the interest rates borne by assets and 
liabilities do not change at the same speed, to the same extent or on the same 
basis. The Company monitors the impact of changes in interest rates on its net 
interest income using several tools. One measure of the Company’s exposure to 
differential changes in interest rates between assets and liabilities is an interest 
rate risk management test. 

This test measures the impact on net interest income of an immediate change in 
interest rates in 100-basis point increments as set forth in the following table: 

Change in Interest Rates 
(in Basis Points) 

Percentage Change in 
Net Interest Income(1)

+400 
+300 
+200 
+100 
–100 
–200 

(10.1)
(9.0)
(6.3)
(2.5)
1.2
2.6

(1)

  The percentage change in this column represents net interest income for 12 months in various 
rate scenarios versus the net interest income in a stable interest rate environment. 

The changes in the table above are within the Company’s policy parameters. 

The Company’s primary objective in managing interest rate risk is to minimize 
the adverse impact of changes in interest rates on the Company’s net interest 
income and capital, while structuring the Company’s asset-liability structure to 
obtain the maximum yield-cost spread on that structure. The Company relies 
primarily on its asset-liability structure to control interest rate risk. 

Liquidity is provided by maintaining an adequate level of liquid assets that 
includes cash and due from banks, federal funds sold and other temporary 
investments. Liquid assets totaled $356,430,000 on December 31, 2017, 
compared with $239,334,000 on December 31, 2016. In each of these two 
years, deposit and borrowing activity has generally been adequate to support 
asset activity. 

The sources of funds for dividends paid by the Company are dividends received 
from the Bank and liquid funds held by the Company. The Company and the 
Bank are regulated enterprises and their abilities to pay dividends are subject to 
regulatory review and restriction. Certain regulatory and statutory restrictions 
exist regarding dividends, loans and advances from the Bank to the Company. 
Generally, the Bank has the ability to pay dividends to the Company subject to 
minimum regulatory capital requirements. 

Capital Adequacy 

Total stockholders’ equity was $260,297,000 at December 31, 2017, 
compared with $240,041,000 at December 31, 2016. The Company’s 
equity increased primarily as a result of earnings and a decrease on other 
comprehensive loss, net of taxes, offset somewhat by dividends paid. Other 
comprehensive loss, net of taxes, decreased primarily as a result of a decrease 
in unrealized losses on securities transferred from available-for-sale to held-
to-maturity and a decrease in unrealized losses on securities available-for-sale. 
This was offset, somewhat, by an increase in the pension liability, net of taxes. 
The reduction in the value of the Company’s deferred tax asset of $8.4 million 
impacted the Company’s total equity as a reduction to retained earnings. 

Federal banking regulators have issued risk-based capital guidelines, which assign 
risk factors to asset categories and off-balance-sheet items. The following table 
reflects capital ratios computed utilizing the recently implemented Basel III 
regulatory capital framework:

Financial Instruments with Off-Balance-Sheet Risk 

The Company is party to financial instruments with off-balance-sheet risk in 
the normal course of business to meet the financing needs of its customers. 
These financial instruments primarily include commitments to originate and 
sell loans, standby letters of credit, unused lines of credit and unadvanced 
portions of construction loans. The instruments involve, to varying degrees, 
elements of credit and interest rate risk in excess of the amount recognized 
in the consolidated balance sheet. The contract or notional amounts of those 
instruments reflect the extent of involvement the Company has in these 
particular classes of financial instruments. 

The Company’s exposure to credit loss in the event of nonperformance by the 
other party to the financial instrument for loan commitments, standby letters 
of credit and unadvanced portions of construction loans is represented by the 
contractual amount of those instruments. The Company uses the same credit 
policies in making commitments and conditional obligations as it does for on-
2016
Contract or Notional Amount 
balance-sheet instruments. Financial instruments with off-balance-sheet risk at 
(dollars in thousands)
December 31 are as follows: 
Financial instruments whose contract amount  

2017  

represents credit risk: 

  Commitments to originate 1–4 family mortgages  
  Standby and commercial letters of credit  
  Unused lines of credit  
  Unadvanced portions of construction loans  
  Unadvanced portions of other loans

   362,357

 52,224

Commitments to originate loans, unadvanced portions of construction loans 
and unused letters of credit are generally agreements to lend to a customer, 
provided there is no violation of any condition established in the contract. 
Commitments generally have fixed expiration dates or other termination clauses 
and may require payment of a fee. Since many of the commitments are expected 
to expire without being drawn upon, the total commitment amounts do not 
necessarily represent future cash requirements. The Company evaluates each 
customer’s creditworthiness on a case-by-case basis. The amount of collateral 
obtained, if deemed necessary by the Company upon extension of credit, is 
based on management’s credit evaluation of the borrower. 

Standby letters of credit are conditional commitments issued by the Company 
to guarantee the performance by a customer to a third party. The credit risk 
involved in issuing letters of credit is essentially the same as that involved in 
extending loan facilities to customers. The fair value of standby letters of credit 
was $66,000 and $44,000 for 2017 and 2016, respectively.

  1. Summary of Significant Accounting Policies 

BASIS OF FINANCIAL STATEMENT PRESENTATION 

The consolidated financial statements include the accounts of Century Bancorp, 
Inc. (the “Company”) and its wholly owned subsidiary, Century Bank and Trust 
Company (the “Bank”). The consolidated financial statements also include 
the accounts of the Bank’s wholly owned subsidiaries, Century Subsidiary 
Investments, Inc. (“CSII”), Century Subsidiary Investments, Inc. II (“CSII II”), 
Century Subsidiary Investments, Inc. III (“CSII III”) and Century Financial 
Services Inc. (“CFSI”). CSII, CSII II, and CSII III are engaged in buying, selling and 
holding investment securities. CFSI has the power to engage in financial agency, 
securities brokerage, and investment and financial advisory services and related 
securities credit. The Company also owns 100% of Century Bancorp Capital 
Trust II (“CBCT II”). The entity is an unconsolidated subsidiary of the Company. 

All significant intercompany accounts and transactions have been eliminated 
in consolidation. The Company provides a full range of banking services to 
individual, business and municipal customers in Massachusetts, New Hampshire, 
Rhode Island, Connecticut and New York. As a bank holding company, the 
Company is subject to the regulation and supervision of the Federal Reserve 
Board. The Bank, a state chartered financial institution, is subject to supervision 
and regulation by applicable state and federal banking agencies, including the 
Federal Reserve Board, the Federal Deposit Insurance Corporation (the “FDIC”) 
and the Commonwealth of Massachusetts Commissioner of Banks. The Bank is 
also subject to various requirements and restrictions under federal and state 
law, including requirements to maintain reserves against deposits, restrictions 
on the types and amounts of loans that may be granted and the interest that 
may be charged thereon, and limitations on the types of investments that may 
be made and the types of services that may be offered. Various consumer laws 
and regulations also affect the operations of the Bank. In addition to the impact 
of regulation, commercial banks are affected significantly by the actions of the 
Federal Reserve Board as it attempts to control the money supply and credit 
availability in order to influence the economy. All aspects of the Company’s 
business are highly competitive. The Company faces aggressive competition 
from other lending institutions and from numerous other providers of financial 
services. The Company has one reportable operating segment. 

The financial statements have been prepared in conformity with accounting 
principles generally accepted in the United States of America and general 
practices within the banking industry. In preparing the financial statements, 
management is required to make estimates and assumptions that affect the 
reported amounts of assets and liabilities as of the date of the balance sheet 
and revenues and expenses for the period. Actual results could differ from 
those estimates. 

Material estimates that are susceptible to change in the near term relate to 
the allowance for loan losses. Management believes that the allowance for loan 
losses is adequate based on a review of factors, including historical charge-
off rates with additional allocations based on qualitative risk factors for each 
category and general economic factors. While management uses available 
information to recognize loan losses, future additions to the allowance for loan 
losses may be necessary based on changes in economic conditions. In addition, 
regulatory agencies periodically review the Company’s allowance for loan losses. 
Such agencies may require the Company to recognize additions to the allowance 
for loan losses based on their judgments about information available to them at 
the time of their examination. Certain reclassifications are made to prior-year 
amounts whenever necessary to conform with the current-year presentation. 

FAIR VALUE MEASUREMENTS 

The Company follows FASB ASC 820-10, Fair Value Measurements and 
Disclosures, which among other things, requires enhanced disclosures about 
assets and liabilities carried at fair value. ASC 820-10 establishes a hierarchal 
disclosure framework associated with the level of pricing observability utilized 
in measuring financial instruments at fair value. The three broad levels of the 
hierarchy are as follows: 

23

Level I — Quoted prices are available in active markets for identical assets or 
liabilities as of the reported date. The type of financial instruments included 
in Level I are highly liquid cash instruments with quoted prices, such as G-7 
government, agency securities, listed equities and money market securities, as 
well as listed derivative instruments. 

Level II — Pricing inputs are other than quoted prices in active markets, which 
are either directly or indirectly observable as of the reported date. The nature 
of these financial instruments includes cash instruments for which quoted 
prices are available but traded less frequently, derivative instruments whose fair 
value has been derived using a model where inputs to the model are directly 
observable in the market or can be derived principally from or corroborated by 
observable market data, and instruments that are fair valued using other financial 
instruments, the parameters of which can be directly observed. Instruments that 
are generally included in this category are corporate bonds and loans, mortgage 
whole loans, municipal bonds and over the counter (“OTC”) derivatives. 

Level III — These instruments have little to no pricing observability as of 
the reported date. These financial instruments do not have two-way markets 
and are measured using management’s best estimate of fair value, where the 
inputs into the determination of fair value require significant management 
judgment or estimation. Instruments that are included in this category generally 
include certain commercial mortgage loans, certain private equity investments, 
distressed debt, and noninvestment grade residual interests in securitizations as 
well as certain highly structured OTC derivative contracts. 

CASH AND CASH EQUIVALENTS 

For purposes of reporting cash flows, cash equivalents include highly liquid 
assets with an original maturity of three months or less. Highly liquid assets 
include cash and due from banks, federal funds sold and certificates of deposit. 

SHORT-TERM INVESTMENTS 

As of December 31, 2017 and 2016, short-term investments include highly 
liquid certificates of deposit with original maturities of more than 90 days but 
less than one year. 

INVESTMENT SECURITIES 

Debt securities that the Company has the positive intent and ability to hold to 
maturity are classified as held-to-maturity and reported at amortized cost; debt 
and equity securities that are bought and held principally for the purpose of 
selling are classified as trading and reported at fair value, with unrealized gains 
and losses included in earnings; and debt and equity securities not classified 
as either held-to-maturity or trading are classified as available-for-sale and 
reported at fair value, with unrealized gains and losses excluded from earnings 
and reported as a separate component of stockholders’ equity, net of estimated 
related income taxes. The Company has no securities held for trading. 

Premiums and discounts on investment securities are amortized or accreted 
into income by use of the level-yield method. Gains and losses on the sale 
of investment securities are recognized on the trade date on a specific 
identification basis. 

Management also considers the Company’s capital adequacy, interest-rate risk, 
liquidity and business plans in assessing whether it is more likely than not that 
the Company will sell or be required to sell the investment securities before 
recovery. If the Company determines that a decline in fair value is OTTI and that 
it is more likely than not that the Company will not sell or be required to sell 
the investment security before recovery of its amortized cost, the credit portion 
of the impairment loss is recognized in the Company’s consolidated statement 
of income and the noncredit portion is recognized in accumulated other 
comprehensive income. The credit portion of the OTTI impairment represents 
the difference between the amortized cost and the present value of the expected 
future cash flows of the investment security. If the Company determines that 
a decline in fair value is OTTI and it is more likely than not that it will sell or 

Century Bancorp, Inc.  AR ’17Notes to Consolidated Financial Statementsbe required to sell the investment security before recovery of its amortized 
cost, the entire difference between the amortized cost and the fair value of the 
security will be recognized in the Company’s consolidated statement of income. 

The transfer of a security between categories of investments shall be accounted 
for at fair value. For a debt security transferred into the held-to-maturity 
category from the available-for-sale category, the unrealized holding gain or 
loss at the date of the transfer shall continue to be reported in a separate 
component of shareholders’ equity but shall be amortized over the remaining 
life of the security as an adjustment of yield in a manner consistent with the 
amortization of any premium or discount. The amortization of an unrealized 
holding gain or loss reported in equity will offset or mitigate the effect on 
interest income of the amortization of the premium or discount for that held-to-
maturity security. 

The sale of a security held-to-maturity may occur after a substantial portion (at 
least 85%) of the principal outstanding at acquisition due either to prepayments 
on the debt security or to scheduled payments on a debt security payable 
in equal installments over its term. For variable rate securities, the scheduled 
payments need not be equal. 

FEDERAL HOME LOAN BANK STOCK 

The Bank, as a member of the Federal Home Loan Bank of Boston (“FHLBB”), 
is required to maintain an investment in capital stock of the FHLBB. Based on 
redemption provisions, the stock has no quoted market value and is carried 
at cost. At its discretion, the FHLBB may declare dividends on the stock. The 
Company reviews for impairment based on the ultimate recoverability of the cost 
basis of the stock. As of December 31, 2017, no impairment has been recognized. 

LOANS HELD FOR SALE 

Loans originated and intended for sale in the secondary market are carried at the 
lower of cost or estimated fair value in the aggregate. Net unrealized losses, if 
any, are recognized through a valuation allowance by charges to income. 

LOANS 

Interest on loans is recognized based on the daily principal amount outstanding. 
Accrual of interest is discontinued when loans become ninety days delinquent 
unless the collateral is sufficient to cover both principal and interest and the 
loan is in the process of collection. Past-due status is based on contractual 
terms of the loan. Loans, including impaired loans, on which the accrual of 
interest has been discontinued, are designated nonaccrual loans. When a loan 
is placed on nonaccrual, all income that has been accrued but remains unpaid 
is reversed against current period income, and all amortization of deferred 
loan costs and fees is discontinued. Nonaccrual loans may be returned to an 
accrual status when principal and interest payments are not delinquent or 
the risk characteristics of the loan have improved to the extent that there no 
longer exists a concern as to the collectibility of principal and interest. Income 
received on nonaccrual loans is either recorded in income or applied to the 
principal balance of the loan, depending on management’s evaluation as to the 
collectibility of principal. 

Loan origination fees and related direct loan origination costs are offset, and the 
resulting net amount is deferred and amortized over the life of the related loans 
using the level-yield method. Prepayments are not initially considered when 
amortizing premiums and discounts. 

The Bank measures impairment for impaired loans at either the fair value of 
the loan, the present value of the expected future cash flows discounted at 
the loan’s effective interest rate or the fair value of the collateral if the loan is 
collateral dependent. This method applies to all loans, uncollateralized as well as 
collateralized, except large groups of smaller-balance homogeneous loans such 
as residential real estate and consumer loans that are collectively evaluated for 
impairment and loans that are measured at fair value. For collateral dependent 
loans, the amount of the recorded investment in a loan that exceeds the fair 
value of the collateral is charged-off against the allowance for loan losses in 
lieu of an allocation of a specific allowance when such an amount has been 

identified definitively as uncollectible. Management considers the payment 
status, net worth and earnings potential of the borrower, and the value and cash 
flow of the collateral as factors to determine if a loan will be paid in accordance 
with its contractual terms. Management does not set any minimum delay of 
payments as a factor in reviewing for impaired classification. Loans are charged-
off when management believes that the collectibility of the loan’s principal is 
not probable. The specific factors that management considers in making the 
determination that the collectibility of the loan’s principal is not probable 
include the delinquency status of the loan, the fair value of the collateral, if 
secured, and, the financial strength of the borrower and/or guarantors. In 
addition, criteria for classification of a loan as in-substance foreclosure has 
been modified so that such classification need be made only when a lender is in 
possession of the collateral. The Bank measures the impairment of troubled debt 
restructurings using the pre-modification effective rate of interest. 

TRANSFERS OF FINANCIAL ASSETS 

Transfers of financial assets, typically residential mortgages and loan 
participations for the Company, are accounted for as sales when control over 
the assets has been surrendered. Control over transferred assets is deemed 
to be surrendered when (1) the assets have been isolated from the Company, 
(2) the transferee obtains the right (free of conditions that constrain it from 
taking advantage of that right) to pledge or exchange the transferred assets, and 
(3) the Company does not maintain effective control over the transferred assets. 

ACQUIRED LOANS 

In accordance with FASB ASC 310-30, Loans and Debt Securities Acquired with 
Deteriorated Credit Quality (formerly Statement of Position (“SOP”) No. 03-3, 
“Accounting for Certain Loans or Debt Securities Acquired in a Transfer”) the 
Company reviews acquired loans for differences between contractual cash flows 
and cash flows expected to be collected from the Company’s initial investment 
in the acquired loans to determine if those differences are attributable, at least 
in part, to credit quality. If those differences are attributable to credit quality, 
the loan’s contractually required payments received in excess of the amount of 
its cash flows expected at acquisition, or nonaccretable discount, is not accreted 
into income. FASB ASC 310-30 requires that the Company recognize the excess 
of all cash flows expected at acquisition over the Company’s initial investment in 
the loan as interest income using the interest method over the term of the loan. 
This excess is referred to as accretable discount and is recorded as a reduction 
of the loan balance. 

Loans which, at acquisition, do not have evidence of deterioration of credit 
quality since origination are outside the scope of FASB ASC 310-30. For such 
loans, the discount, if any, representing the excess of the amount of reasonably 
estimable and probable discounted future cash collections over the purchase 
price, is accreted into interest income using the interest method over the term of 
the loan. Prepayments are not considered in the calculation of accretion income. 
Additionally, the discount is not accreted on nonperforming loans. 

When a loan is paid off, the excess of any cash received over the net investment 
is recorded as interest income. In addition to the amount of purchase discount 
that is recognized at that time, income may include interest owed by the 
borrower prior to the Company’s acquisition of the loan, interest collected if on 
nonperforming status, prepayment fees and other loan fees. There were no new 
loans acquired during the year ended December 31, 2017. 

NONPERFORMING ASSETS 

In addition to nonperforming loans, nonperforming assets include other real 
estate owned. Other real estate owned is comprised of properties acquired 
through foreclosure or acceptance of a deed in lieu of foreclosure. Other real 
estate owned is recorded initially at the lower of cost or the estimated fair 
value less costs to sell. When such assets are acquired, the excess of the loan 
balance over the estimated fair value of the asset is charged to the allowance for 
loan losses. An allowance for losses on other real estate owned is established 
by a charge to earnings when, upon periodic evaluation by management, 
further declines in the estimated fair value of properties have occurred. 

24

Century Bancorp, Inc.  AR ’17Notes to Consolidated Financial StatementsSuch evaluations are based on an analysis of individual properties as well as a 
general assessment of current real estate market conditions. Holding costs and 
rental income on properties are included in current operations, while certain 
costs to improve such properties are capitalized. Gains and losses from the sale 
of other real estate owned are reflected in earnings when realized. 

ALLOWANCE FOR LOAN LOSSES 

The allowance for loan losses is based on management’s evaluation of the 
quality of the loan portfolio and is used to provide for losses resulting from 
loans that ultimately prove uncollectible. The components of the allowance for 
loan losses represent estimates based upon Accounting Standards Codification 
(“ASC”) Topic 450, contingencies, and ASC Topic 310 Receivables. ASC 
Topic 450 applies to homogenous loan pools such as consumer installment, 
residential mortgages, consumer lines of credit and commercial loans that are 
not individually evaluated for impairment under ASC Topic 310. In determining 
the level of the allowance, periodic evaluations are made of the loan portfolio, 
which takes into account factors such as the characteristics of the loans, loan 
status, financial strength of the borrowers, value of collateral securing the 
loans and other relevant information sufficient to reach an informed judgment. 
The allowance is increased by provisions charged to income and reduced by 
loan charge-offs, net of recoveries. Management maintains an allowance for 
loan losses to absorb losses inherent in the loan portfolio. The allowance is 
based on assessments of the probable estimated losses inherent in the loan 
portfolio. Management’s methodology for assessing the appropriateness of the 
allowance consists of several key elements, which include the specific allowances, 
if appropriate, for identified problem loans, formula allowance, and possibly an 
unallocated allowance. Arriving at an appropriate level of allowance for loan 
losses necessarily involves a high degree of judgment. 

While management uses available information in establishing the allowance for 
loan losses, future adjustments to the allowance may be necessary if economic 
conditions differ substantially from the assumptions used in making the 
evaluations. Loans are charged-off in whole or in part when, in management’s 
opinion, collectibility is not probable. The specific factors that management 
considers in making the determination that the collectibility of the loan’s 
principal is not probable include the delinquency status of the loan, the fair value 
of the collateral and the financial strength of the borrower and/or guarantors. 

Under ASC Topic 310, a loan is impaired, based upon current information and 
in management’s opinion, when it is probable that the loan will not be repaid 
according to its original contractual terms, including both principal and interest, 
or if a loan is designated as a Troubled Debt Restructuring (“TDR”). Specific 
allowances for loan losses entail the assignment of allowance amounts to 
individual loans on the basis of loan impairment. Under this method, loans are 
selected for evaluation based upon a change in internal risk rating, occurrence of 
delinquency, loan classification or nonaccrual status. A specific allowance amount 
is allocated to an individual loan when such loan has been deemed impaired 
and when the amount of a probable loss is able to be estimated on the basis of: 
(a) present value of anticipated future cash flows, (b) the loan’s observable fair 
market price or (c) fair value of collateral if the loan is collateral dependent. For 
collateral dependent loans, the amount of the recorded investment in a loan that 
exceeds the fair value of the collateral is charged-off against the allowance for 
loan losses in lieu of an allocation of a specific allowance when such an amount 
has been identified definitively as uncollectible. 

In estimating probable loan loss under ASC Topic 450 management considers 
numerous factors, including historical charge-offs and subsequent recoveries. The 
formula allowances are based on evaluations of homogenous loans to determine 
the allocation appropriate within each portfolio segment. Formula allowances are 
based on internal risk ratings or credit ratings from external sources. Individual 
loans within the commercial and industrial, commercial real estate and real estate 
construction loan portfolio segments are assigned internal risk ratings to group 
them with other loans possessing similar risk characteristics. Changes in risk 
grades affect the amount of the formula allowance. Risk grades are determined by 

25

reviewing current collateral value, financial information, cash flow, payment history 
and other relevant facts surrounding the particular credit. On these loans, the 
formula allowances are based on the risk ratings, the historical loss experience, 
and the loss emergence period. Historical loss data and loss emergence periods 
are developed based on the Company’s historical experience. For larger loans 
with available external credit ratings, these ratings are utilized rather than the 
Company’s risk ratings. The historical loss factor and loss emergence periods for 
these loans are based on data published by the rating agencies for similar credits 
as the Company has limited internal historical data. For the residential real estate 
and consumer loan portfolios, the formula allowances are calculated by applying 
historical loss experience and the loss emergence period to the outstanding 
balance in each loan category. Loss factors and loss emergence periods are based 
on the Company’s historical net loss experience. 

Additional allowances are added to portfolio segments based on qualitative 
factors. Management considers potential factors identified in regulatory 
guidance. Management has identified certain qualitative factors, which could 
impact the degree of loss sustained within the portfolio. These include market 
risk factors and unique portfolio risk factors that are inherent characteristics 
of the Company’s loan portfolio. Market risk factors may consist of changes to 
general economic and business conditions, such as unemployment and GDP that 
may impact the Company’s loan portfolio customer base in terms of ability to 
repay and that may result in changes in value of underlying collateral. Unique 
portfolio risk factors may include the outlooks for business segments in which 
the Company’s borrowers operate and loan size. The potential ranges for 
qualitative factors are based on historical volatility in losses. The actual amount 
utilized is based on management’s assessment of current conditions. 

After considering the above components, an unallocated component may be 
generated to cover uncertainties that could affect management’s estimate 
of probable losses. These uncertainties include the effects of loans in new 
geographical areas and new industries. The unallocated component of the 
allowance reflects the margin of imprecision inherent in the underlying 
assumptions used in the methodologies for estimating allocated and general 
reserves in the portfolio. 

BANK PREMISES AND EQUIPMENT 

Bank premises and equipment are stated at cost less accumulated depreciation 
and amortization. Land is stated at cost. Depreciation is computed using the 
straight-line method over the estimated useful lives of the assets or the terms 
of leases, if shorter. It is general practice to charge the cost of maintenance and 
repairs to operations when incurred; major expenditures for improvements are 
capitalized and depreciated. 

GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS 

Goodwill represents the excess of the cost of an acquisition over the fair value 
of the net assets acquired. Goodwill is not subject to amortization. Identifiable 
intangible assets consist of core deposit intangibles and are assets resulting 
from acquisitions that are being amortized over their estimated useful lives. 
Goodwill and identifiable intangible assets are included in other assets on the 
consolidated balance sheets. The Company tests goodwill for impairment on 
an annual basis, or more often if events or circumstances indicate there may 
be impairment. Goodwill impairment testing is performed at the segment (or 
“reporting unit”) level. Currently, the Company’s goodwill is evaluated at the 
entity level as there is only one reporting unit. Goodwill is assigned to reporting 
units at the date the goodwill is initially recorded. Once goodwill has been 
assigned to reporting units, it no longer retains its association with a particular 
acquisition, and all of the activities within a reporting unit, whether acquired or 
organically grown, are available to support the value of the goodwill. 

Goodwill impairment is evaluated by first assessing qualitative factors (events 
and circumstances) to determine whether it is more likely than not (meaning 
a likelihood of more than 50 percent) that the fair value of a reporting unit 
is less than its carrying amount. If, after considering all relevant events and 
circumstances, an entity determines it is not more likely than not that the fair 

Century Bancorp, Inc.  AR ’17Notes to Consolidated Financial Statementsvalue of a reporting unit is less than its carrying amount, then performing the 
two-step impairment test will be unnecessary. 

The first step, in the two-step impairment test, used to identify potential 
impairment, involves comparing each reporting unit’s fair value to its carrying 
value including goodwill. If the fair value of a reporting unit exceeds its carrying 
value, applicable goodwill is considered not to be impaired. If the carrying value 
exceeds fair value, there is an indication of impairment and the second step is 
performed to measure the amount of impairment. 

SERVICING 

The Company services mortgage loans for others. Mortgage servicing assets 
are recognized as separate assets when rights are acquired through purchase or 
through sale of financial assets. Fair value is determined using prices for similar 
assets with similar characteristics, when available, or based upon discounted 
cash flows using market-based assumptions. The valuation model incorporates 
assumptions that market participants would use in estimating future net 
servicing income, such as the cost to service, the discount rate, an inflation rate, 
ancillary income, prepayment speeds and default rates and losses. Capitalized 
servicing rights are reported in other assets and are amortized into loan servicing 
fee income in proportion to, and over the period of, the estimated future 
net servicing income of the underlying financial assets. Servicing assets are 
evaluated for impairment based upon the fair value of the rights as compared to 
amortized cost. Impairment is determined by stratifying rights by predominant 
risk characteristics, such as interest rates and terms. Impairment is recognized 
through a valuation allowance for an individual stratum, to the extent that 
fair value is less than the capitalized amount for the stratum. Changes in the 
valuation allowance are reported in loan servicing fee income. 

STOCK OPTION ACCOUNTING 

The Company follows the fair value recognition provisions of FASB ASC 718, 
Compensation — Stock Compensation for all share-based payments. The 
Company’s method of valuation for share-based awards granted utilizes the 
Black-Scholes option-pricing model. The Company will recognize compensation 
expense for its awards on a straight-line basis over the requisite service period 
for the entire award (straight-line attribution method), ensuring that the amount 
of compensation cost recognized at any date at least equals the portion of the 
grant-date fair value of the award that is vested at that time. 

During 2000 and 2004, common stockholders of the Company approved 
stock option plans (the “Option Plans”) that provide for granting of options 
to purchase up to 150,000 shares of Class A common stock per plan. Under 
the Option Plans, all officers and key employees of the Company are eligible 
to receive nonqualified or incentive stock options to purchase shares of Class 
A common stock. The Option Plans are administered by the Compensation 
Committee of the Board of Directors, whose members are ineligible to 
participate in the Option Plans. Based on management’s recommendations, 
the Committee submits its recommendations to the Board of Directors as to 
persons to whom options are to be granted, the number of shares granted 
to each, the option price (which may not be less than 85% of the fair market 
value for nonqualified stock options, or the fair market value for incentive stock 
options, of the shares on the date of grant) and the time period over which the 
options are exercisable (not more than ten years from the date of grant). There 
were no options to purchase shares of Class A common stock outstanding at 
December 31, 2017. 

The Company uses the fair value method to account for stock options. There 
were no options granted during 2017 and 2016. 

INCOME TAXES 

The Company uses the asset and liability method in accounting for income 
taxes. Under the asset and liability method, deferred tax assets and liabilities are 
recognized for the future tax consequences attributable to differences between 
the financial statement carrying amounts of existing assets and liabilities and 
their respective tax bases. Deferred tax assets and liabilities are measured using 

enacted tax rates expected to apply to taxable income in the years in which 
temporary differences are expected to be recovered or settled. Under this 
method, the effect on deferred tax assets and liabilities of a change in tax rates is 
recognized in income in the period that includes the enactment date. 

The Company accounts for uncertain tax positions in accordance with 
FASB ASC 740. 

The Company classifies interest resulting from underpayment of income taxes 
as income tax expense in the first period the interest would begin accruing 
according to the provisions of the relevant tax law. 

The Company classifies penalties resulting from underpayment of income taxes 
as income tax expense in the period for which the Company claims or expects to 
claim an uncertain tax position or in the period in which the Company’s judgment 
changes regarding an uncertain tax position. 

For tax years beginning after December 31, 2017, the corporate alternative 
minimum tax (“AMT”) has been repealed. For 2018 through 2021, the AMT 
credit carryforward can offset regular tax liability and is refundable in an amount 
equal to 50% (100% for 2021) of the excess of the minimum tax credit for 
the tax year over the amount of the credit allowable for the year against regular 
tax liability. Accordingly, the full amount of the AMT credit carryforward will be 
recovered in tax years beginning before 2022. As a result of the change, the 
Company has classified its AMT credit carryforward as currently receivable.

EARNINGS PER SHARE (“EPS”) 

Class A and Class B shares participate equally in undistributed earnings. Under 
the Company’s Articles of Organization, the holders of Class A Common Stock 
are entitled to receive dividends per share equal to at least 200% of dividends 
paid, if any, from time to time, on each share of Class B Common Stock. 

Diluted EPS includes the dilutive effect of common stock equivalents; basic EPS 
excludes all common stock equivalents. The only common stock equivalents for 
the Company are stock options. 

The company utilizes the two class method for reporting EPS. The two-class 
method is an earnings allocation formula that treats Class A and Class B shares 
as having rights to earnings that otherwise would have been available only to 
Class A shareholders and Class B shareholders as if converted to Class A shares. 

TREASURY STOCK 

Effective July 1, 2004, companies incorporated in Massachusetts became subject 
to Chapter 156D of the Massachusetts Business Corporation Act, provisions of 
which eliminate the concept of treasury stock and provide that shares reacquired 
by a company are to be treated as authorized but unissued shares. 

PENSION 

The Company provides pension benefits to its employees under a 
noncontributory, defined benefit plan, which is funded on a current basis in 
compliance with the requirements of the Employee Retirement Income Security 
Act of 1974 (“ERISA”) and recognizes costs over the estimated employee 
service period. 

The Company also has a Supplemental Executive Insurance/Retirement Plan 
(“the Supplemental Plan”), which is limited to certain officers and employees 
of the Company. The Supplemental Plan is accrued on a current basis and 
recognizes costs over the estimated employee service period. 

Executive officers of the Company or its subsidiaries who have at least one year 
of service may participate in the Supplemental Plan. The Supplemental Plan is 
voluntary. Individual life insurance policies, which are owned by the Company, 
are purchased covering the life of each participant. 

The Company utilizes a full yield curve approach in the estimation of the service 
and interest components by applying the specific spot rates along the yield 
curve used in the determination of the benefit obligation to the underlying 
projected cash flows.

Century Bancorp, Inc.  AR ’17Notes to Consolidated Financial StatementsRECENT ACCOUNTING DEVELOPMENTS 

In February 2018, the Financial Accounting Standards Board (“FASB”) issued 
Accounting Standards Update (“ASU”) 2018-02, Income Statement—
Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax 
Effects from Accumulated Other Comprehensive Income. The amendments in this 
ASU allow a reclassification from accumulated other comprehensive income to 
retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs 
Act. Consequently, the amendments eliminate the stranded tax effects resulting 
from the Tax Cuts and Jobs Act and will improve the usefulness of information 
reported to financial statement users. However, because the amendments only 
relate to the reclassification of the income tax effects of the Tax Cuts and Jobs 
Act, the underlying guidance that requires that the effect of a change in tax laws 
or rates be included in income from continuing operations is not affected. The 
amendments in this ASU are effective for all entities for fiscal years beginning 
after December 15, 2018, and interim periods within those fiscal years. Early 
adoption of the amendments in this ASU is permitted, including adoption in any 
interim period, (1) for public business entities for reporting periods for which 
financial statements have not yet been issued and (2) for all other entities 
for reporting periods for which financial statements have not yet been made 
available for issuance. The amendments in this ASU should be applied either in 
the period of adoption or retrospectively to each period (or periods) in which 
the effect of the change in the U.S. federal corporate income tax rate in the Tax 
Cuts and Jobs Act is recognized. The Company will adopt this update in the first 
quarter of 2018 and will apply the effects of the changes retrospectively. The 
effect of the changes is approximately $3.8 million.

In July 2017, FASB issued ASU 2017-11, Earnings Per Share (Topic 260), 
Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging 
(Topic 815): I. Accounting for Certain Financial Instruments with Down Round 
Features II. Replacement of the Indefinite Deferral for Mandatorily Redeemable 
Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily 
Redeemable Noncontrolling Interest with a Scope Exception. For public entities, 
this ASU is effective for annual reporting periods beginning after December 15, 
2018. Management is currently assessing the applicability of ASU 2017-11 and 
has not determined the impact of the adoption, if any, as of December 31, 2017.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock 
Compensation (Topic 718): Scope of Modification Accounting. FASB issued this 
Update to address the diversity in practice as well as the cost and complexity 
when applying the guidance in Topic 718, Compensation - Stock Compensation, 
to a change to the terms or conditions of a share-based payment award. For 
public entities, this ASU is effective for annual reporting periods beginning 
after December 15, 2017. The effect of this update is not expected to have a 
material impact on the Company’s consolidated financial position.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable 
Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased 
Callable Debt. The FASB is issuing this ASU to amend the amortization period 
for certain purchased callable debt securities held at a premium. The FASB is 
shortening the amortization period for the premium to the earliest call date. 
Under current generally accepted accounting principles (GAAP), entities 
generally amortize the premium as an adjustment of yield over the contractual 
life of the instrument. For public business entities, the amendments in this 
ASU are effective for fiscal years, and interim periods within those fiscal years, 
beginning after December 15, 2018. Management is currently assessing 
the applicability of this ASU and has not determined the impact, if any, as of 
December 31, 2017.

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement 
Benefits (Topic 715) Improving the Presentation of Net Periodic Pension Cost 
and Net Periodic Postretirement Benefit Cost. The amendments in this ASU 
require that an employer disaggregate the service cost component from the other 
components of net benefit cost. The amendments also provide explicit guidance 
on how to present the service cost component and the other components of net 

27

benefit cost in the income statement and allow only the service cost component 
of net benefit cost to be eligible for capitalization. The amendments in this ASU 
are effective for fiscal years beginning after December 15, 2017. Early adoption 
is permitted. This ASU is for presentation purposes only, accordingly, there will 
be no impact on the Company’s consolidated financial position.

In February 2017, the FASB issued ASU 2017-05, Other Income Gains and 
Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20). This 
ASU was issued to clarify the scope of Subtopic 610-20, and to add guidance 
for partial sales of nonfinancial assets. For public entities, this ASU is effective 
for annual reporting periods beginning after December 15, 2017. The effect 
of this update is not expected to have a material impact on the Company’s 
consolidated financial position.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill 
and Other (Topic 350). This ASU was issued to simplify the subsequent 
measurement of goodwill by eliminating Step 2 from the goodwill impairment 
test. For public entities, this ASU is effective for the fiscal years beginning after 
December 15, 2019, including interim periods within those fiscal years. Early 
adoption is permitted and application should be on a prospective basis. The 
effect of this update is not expected to have a material impact on the Company’s 
consolidated financial position.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit 
Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. 
This ASU was issued to provide financial statement users with more decision-
useful information about the expected credit losses on financial instruments and 
other commitments to extend credit held by a reporting entity at each reporting 
date. To achieve this objective, the amendments in this ASU replace the 
incurred loss impairment methodology in current GAAP with a methodology that 
reflects expected credit losses and requires consideration of a broader range 
of reasonable and supportable information to inform credit loss estimates. The 
amendments in this ASU are effective for fiscal years beginning after December 
15, 2019, including interim periods within those fiscal years. The Company is in 
the process of analyzing this ASU and has begun evaluating software solutions 
to help capture information needed to implement this update. The Company has 
not determined the impact, if any, as of December 31, 2017.

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with 
Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. 
The intention of this ASU is to provide additional clarification on specific 
issues brought forth by the FASB and the International Accounting Standards 
Board Joint Transition Resource Group for Revenue Recognition in relation to 
Topic 606 and revenue recognition. This ASU is to have the same effective 
date as ASU 2015-14 which deferred the effective date of ASU 2014-09 to 
December 15, 2017. In May 2014, the FASB issued ASU 2014-09, Revenue 
from Contracts with Customers (Topic 606), which will replace numerous 
requirements in U.S. GAAP, including industry-specific requirements, and provide 
companies with a single revenue recognition model for recognizing revenue from 
contracts with customers. The core principle of the standard is that a company 
should recognize revenue to depict the transfer of promised goods or services 
to customers in an amount that reflects the consideration to which the company 
expects to be entitled in exchange for those goods or services. The two 
permitted transition methods under the new standard are the full retrospective 
method, in which case the standard would be applied to each prior reporting 
period presented and the cumulative effect of applying the standard would be 
recognized at the earliest period shown, or the modified retrospective method, 
in which case the cumulative effect of applying the standard would be recognized 
at the date of initial application. Since the issuance of Update 2014-09, the 
FASB has finalized various amendments to the standard that include corrections, 
improvements and timing modifications. 

In July 2015, the FASB approved the deferral of the new standard’s effective 
date by one year. The new standard is effective for annual reporting periods 

Century Bancorp, Inc.  AR ’17Notes to Consolidated Financial Statementsbeginning after December 15, 2017. The FASB will permit companies to adopt the new standard early, but not before the original effective date of annual reporting 
periods beginning after December 15, 2016.

We monitored FASB activity related to the new standard. A significant amount of the Company’s revenues are derived from interest income on financial assets, which 
are excluded from the scope of the amended guidance. 

In 2017, we established a cross-functional implementation team consisting of representatives from across our business segments. We utilized a bottom-up approach 
to analyze the impact of the standard on our contract portfolio by reviewing our current accounting policies and practices to identify potential differences that would 
result from applying the requirements of the new standard to our revenue contracts. In addition, we identified and implemented appropriate changes to our business 
processes, systems and controls to support recognition and disclosure under the new standard. The implementation team has reported the findings and progress of 
the project to management on a frequent basis over this past year.

During 2017, we completed our evaluation of the potential changes from adopting the new standard on our future financial reporting and disclosures. In the third 
quarter of 2017, we finalized our contract reviews. The Company did not identify any significant changes in the timing of revenue recognition when considering the 
amended accounting guidance.

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires lessees to put most leases on their balance sheet but recognize expenses on their income 
statements in a manner similar to today’s accounting. This ASU also eliminates today’s real estate-specific provisions for all companies. For lessors, this ASU modifies 
the classification criteria and the accounting for sales-type and direct financing leases. This ASU is effective for fiscal years beginning after December 15, 2018, 
including interim periods therein. Early adoption is permitted. The Company has begun analyzing this ASU and will be assessing implementation steps beginning in 
2018. The Company has not determined the impact, if any, as of December 31, 2017.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash. The amendments of this ASU was issued to require that a 
statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted 
cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when 
reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. For public entities, this ASU is effective for the fiscal 
years beginning after December 15, 2017, including interim periods within those fiscal years. The effect of this update is not expected to have a material impact on the 
Company’s consolidated financial position.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 326) Classification of Certain Cash Receipts and Cash Payments. Stakeholders indicated 
that there is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement 
of Cash Flows, and other Topics. This ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments in 
this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The effect of this 
update is not expected to have a material impact on the Company’s consolidated financial position.

In January 2016, FASB issued ASU 2016-1, “Financial Instruments-Overall” (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities. 
This ASU significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation 
of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial 
instruments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods therein. The effect of this update is not expected to have 
a material impact on the Company’s consolidated financial position.

  2. Cash and Due from Banks 

The Company is required to maintain a portion of its cash and due from banks as a reserve balance under the Federal Reserve Act. Such reserve is calculated based 
upon deposit levels and amounted to $0 at December 31, 2017, and $0 at December 31, 2016.

The weighted average remaining life of investment securities available-for-sale at December 31, 2017, was 5.7 years. The contractual maturities, which were used 
in the table above, of mortgage-backed securities, will differ from the actual maturities due to the ability of the issuers to prepay underlying obligations. Also, 
$313,037,000 of the securities are floating rate or adjustable rate and reprice prior to maturity. 

As of December 31, 2017 and December 31, 2016, management concluded that the unrealized losses of its investment securities are temporary in nature since they 
are not related to the underlying credit quality of the issuers, and the Company does not intend to sell these debt securities and it is not more likely than not that it 
will be required to sell these debt securities before the anticipated recovery of its remaining amortized cost. In making its other-than-temporary impairment evaluation, 
the Company considered the fact that the principal and interest on these securities are from issuers that are investment grade. The change in the unrealized losses on 
the Obligations Issued by States and Political Subdivisions, Privately Issued Residential Mortgage-Backed Securities and Other Debt Securities was primarily caused by 
changes in credit spreads and liquidity issues in the marketplace. 

The unrealized loss on SBA Backed Securities and U.S. Government Agency and Sponsored Enterprises Mortgage-Backed Securities related primarily to interest rates 
and not credit quality and because the Company has the ability and intent to hold these investments until recovery of fair value, which may be maturity. The Company 
does not consider these investments to be other-than-temporarily impaired at December 31, 2017 and December 31, 2016. 

In evaluating the underlying credit quality of a security, management considers several factors such as the credit rating of the obligor and the issuer, if applicable. 
Internal reviews of issuer financial statements are performed as deemed necessary. In the case of privately issued mortgage-backed securities, the performance of the 
underlying loans is analyzed as deemed necessary to determine the estimated future cash flows of the securities. Factors considered include the level of subordination, 
current and estimated future default rates, current and estimated prepayment rates, estimated loss severity rates, geographic concentrations and origination dates 
of underlying loans. In the case of marketable equity securities, the severity of the unrealized loss, the length of time the unrealized loss has existed, and the issuer’s 
financial performance are considered. 

The following table shows the temporarily impaired securities of the Company’s available-for-sale portfolio at December 31, 2017. This table shows the unrealized 
market loss of securities that have been in a continuous unrealized loss position for 12 months or less and a continuous loss position for 12 months and longer.

$12,000 from the proceeds of sales of held-to-maturity securities of $192,000 for the year ending December 31, 2016. The sales from securities held-to-maturity

The weighted average remaining life of investment securities held-to-maturity at December 31, 2017, was 4.3 years. Included in the weighted average remaining life 
calculation at December 31, 2017, were $20,496,000 of U.S. Government Sponsored Enterprises obligations that are callable at the discretion of the issuer. The 
contractual maturities, which were used in the table above, of mortgage-backed securities, will differ from the actual maturities due to the ability of the issuers to 
prepay underlying obligations. Also, $159,000 of the securities are floating rate or adjustable rate and reprice prior to maturity. 

As of December 31, 2017 and December 31, 2016, management concluded that the unrealized losses of its investment securities are temporary in nature since 
they are not related to the underlying credit quality of the issuers, and the Company does not intend to sell these debt securities and it is not more likely than not 
that it will be required to sell these debt securities before the anticipated recovery of their remaining amortized costs. In making its other-than-temporary impairment 
evaluation, the Company considered the fact that the principal and interest on these securities are from issuers that are investment grade. 

The unrealized loss on U.S. Government Sponsored Enterprises, SBA Backed Securities and U.S. Government Sponsored Enterprises Mortgage-Backed Securities 
related primarily to interest rates and not credit quality, and because the Company does not intend to sell any of these securities and it is not more likely than not that 
it will be required to sell these securities before the anticipated recovery of the remaining amortized cost, the Company does not consider these investments to be 
other-than-temporarily impaired at December 31, 2017 and December 31, 2016. 

In evaluating the underlying credit quality of a security, management considers several factors such as the credit rating of the obligor and the issuer, if applicable. 
Internal reviews of issuer financial statements are performed as deemed necessary.

At December 31, 2017, and December 31, 2016, loans were carried net of discounts of $272,000 and $313,000, respectively. Net deferred fees included in loans 
at December 31, 2017, and December 31, 2016, were $362,000 and $641,000, respectively. 

The Company was servicing mortgage loans sold to others without recourse of approximately $229,533,000 and $229,730,000 at December 31, 2017, and 
December 31, 2016, respectively. The Company had no residential real estate loans held for sale at December 31, 2017 and December 31, 2016. The Company’s 
mortgage servicing rights totaled $1,525,000 and $1,629,000 at December 31, 2017 and December 31, 2016, respectively. 

As of December 31, 2017 and 2016, the Company’s recorded investment in impaired loans was $7,114,000 and $3,830,000, respectively. If an impaired loan is 
placed on nonaccrual, the loan may be returned to an accrual status when principal and interest payments are not delinquent and the risk characteristics have improved 
to the extent that there no longer exists a concern as to the collectibility of principal and interest. At December 31, 2017, there were $ 6,581,000 impaired loans 
with specific reserves of $164,000. At December 31, 2016, there were $3,105,000 of impaired loans with a specific reserve of $173,000. 

Loans are designated as troubled debt restructures when a concession is made on a credit as a result of financial difficulties of the borrower. Typically, such 
concessions consist of a reduction in interest rate to a below-market rate, taking into account the credit quality of the note, or a deferment of payments, principal 
or interest, which materially alters the Bank’s position or significantly extends the note’s maturity date, such that the present value of cash flows to be received is 
materially less than those contractually established at the loan’s origination. Restructured loans are included in the impaired loan category.

A loan is impaired when, based on current information and events, it is probable that a creditor will be unable to collect all amounts due according to the contractual 
terms of the loan agreement. When a loan is impaired, the Company measures impairment based on the present value of expected future cash flows discounted at the 
loan’s effective interest rate, except that as a practical expedient, the Company measures impairment based on a loan’s observable market price or the fair value of the 
collateral if the loan is collateral dependent. Loans are charged-off when management believes that the collectibility of the loan’s principal is not probable. The specific 
factors that management considers in making the determination that the collectibility of the loan’s principal is not probable include; the delinquency status of the loan, 
the fair value of the collateral, if secured, and the financial strength of the borrower and/or guarantors. For collateral dependent loans, the amount of the recorded 
investment in a loan that exceeds the fair value of the collateral is charged-off against the allowance for loan losses in lieu of an allocation of a specific allowance 
amount when such an amount has been identified definitively as uncollectible. The Company’s policy for recognizing interest income on impaired loans is contained 
within Note 1 of the “Notes to Consolidated Financial Statements.”

Troubled Debt Restructurings are identified as a modification in which a concession was granted to a customer who was having financial difficulties. This concession 
may be below market rate, longer amortization/term, or a lower payment amount. The present value calculation of the modification did not result in an increase in the 
allowance for these loans beyond any previously established allocations. 

There were no troubled debt restructurings occurring during the year ended December 31, 2017. 

There was one commercial real estate troubled debt restructuring during the year ended December 31, 2016. The pre-modification and post-modification outstanding 
recorded investment was $2,091,000. The loan was modified in 2016, by reducing the interest rate as well as extending the term on the loan. The financial impact for 
the modification was $16,000 reduction in principal payments and $5,000 reduction in interest payments for 2016. 

There were no commitments to lend additional funds to troubled debt restructuring borrowers. There were no troubled debt restructurings that subsequently 
defaulted during 2017 and 2016.

The Company follows FASB ASC 820-10, Fair Value Measurements and Disclosures, which among other things, requires enhanced disclosures about assets and 
liabilities carried at fair value. ASC 820-10 establishes a hierarchal disclosure framework associated with the level of pricing observability utilized in measuring financial 
instruments at fair value. The three broad levels of the hierarchy are as follows: 

Level I — Quoted prices are available in active markets for identical assets or liabilities as of the reported date. The type of financial instruments included in Level I are 
highly liquid cash instruments with quoted prices such as G-7 government, agency securities, listed equities and money market securities, as well as listed derivative 
instruments. 

Level II — Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these 
financial instruments include cash instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been 
derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, 
and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Instruments which are generally included in this 
category are corporate bonds and loans, mortgage whole loans, municipal bonds and OTC derivatives.

Level III — These instruments have little to no pricing observability as of the reported date. These financial instruments do not have two-way markets and are 
measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. 
Instruments that are included in this category generally include certain commercial mortgage loans, certain private equity investments, distressed debt, non-investment 
grade residual interests in securitizations, as well as certain highly structured OTC derivative contracts.

Impaired loan balances in the table above represent those collateral dependent loans where management has estimated the credit loss by comparing the loan’s carrying 
value against the expected realizable fair value of the collateral. Fair value is generally determined through a review process that includes independent appraisals, 
discounted cash flows, or other external assessments of the underlying collateral, which generally include various Level 3 inputs which are not identifiable. The 
Company discounts the fair values, as appropriate, based on management’s observations of the local real estate market for loans in this category. 

Appraisals, discounted cash flows and real estate tax assessments are reviewed quarterly. There is no specific policy regarding how frequently appraisals will be 
updated. Adjustments are made to appraisals and real estate tax assessments based on management’s estimate of changes in real estate values. Within the past twelve 
months there have been no updated appraisals, however, all impaired loans have been reviewed during the past quarter using either a discounted cash flow analysis or 
other type of real estate tax assessment. The types of adjustments that are made to specific provisions (credits) relate to impaired loans recognized for 2017 for the 
estimated credit loss amounted to $3,000. 

There were no transfers between level 1, 2 and 3 for the year ended December 31, 2017. There were no liabilities measured at fair value on a recurring or 
nonrecurring basis during the year ended December 31, 2017.

SUBORDINATED DEBENTURES 

Subordinated debentures totaled $36,083,000 at December 31, 2017 and 2016. In May 1998, the Company consummated the sale of a trust preferred securities 
offering, in which it issued $29,639,000 of subordinated debt securities due 2029 to its newly formed unconsolidated subsidiary Century Bancorp Capital trust. 
Century Bancorp Capital Trust the issued 2,875,000 shares of Cumulative Trust Preferred with a liquidation value of $10 per share. These securities pay dividends at 
an annualized rate of 8.30%. The Company redeemed through its subsidiary, Century Bancorp Capital Trust, its 8.30% Trust Preferred Securities, January 10, 2005.

In December 2004, the Company consummated the sale of a trust preferred securities offering, in which it issued $36,083,000 of subordinated debt securities due 
2034 to its newly formed unconsolidated subsidiary Century Bancorp Capital Trust II. 

Century Bancorp Capital Trust II then issued 35,000 shares of Cumulative Trust Preferred Securities with a liquidation value of $1,000 per share. These securities 
paid dividends at an annualized rate of 6.65% for the first ten years and then converted to the three-month LIBOR rate plus 1.87% for the remaining 20 years. The 
coupon rate on these securities was 3.46% at December 31, 2017 and 2.83% at December 31, 2016.

OTHER BORROWED FUNDS

14. Earnings per share (“EPS”) 

Class A and Class B shares participate equally in undistributed earnings. Under the Company’s Articles of Organization, the holders of Class A Common Stock are 
entitled to receive dividends per share equal to at least 200% of dividends paid, if any, from time to time, on each share of Class B Common Stock. 

Diluted EPS includes the dilutive effect of common stock equivalents; basic EPS excludes all common stock equivalents. There were no common stock equivalents for 
2017, 2016 and 2015, respectively.

 15. Stockholders’ Equity 

DIVIDENDS 

Holders of the Class A common stock may not vote in the election of directors but may vote as a class to approve certain extraordinary corporate transactions. Holders 
of Class B common stock may vote in the election of directors. Class A common stockholders are entitled to receive dividends per share equal to at least 200% per 
share of that paid, if any, on each share of Class B common stock. Class A common stock is publicly traded. Class B common stock is not publicly traded; however, it 
can be converted on a per share basis to Class A common stock at any time at the option of the holder. Dividend payments by the Company are dependent in part on 
the dividends it receives from the Bank, which are subject to certain regulatory restrictions. 

STOCK OPTION PLAN 

During 2000 and 2004, common stockholders of the Company approved stock option plans (the “Option Plans”) that provide for granting of options for not more 
than 150,000 shares of Class A common stock per plan. Under the Option Plans, all officers and key employees of the Company are eligible to receive nonqualified and 
incentive stock options to purchase shares of Class A common stock. The Option Plans are administered by the Compensation Committee of the Board of Directors, 
whose members are ineligible to participate in the Option Plans. Based on management’s recommendations, the Committee submits its recommendations to the Board 
of Directors as to persons to whom options are to be granted, the number of shares granted to each, the option price (which may not be less than 85% of the fair 
market value for nonqualified stock options, or the fair market value for incentive stock options, of the shares on the date of grant) and the time period over which the 
options are exercisable (not more than ten years from the date of grant). There were no options outstanding at December 31, 2017 and December 31, 2016. 

CAPITAL RATIOS 

The Bank and the Company are subject to various regulatory requirements administered by federal banking agencies. Failure to meet minimum capital requirements 
can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank and 
Company’s financial statements. Under capital adequacy guidelines and regulatory framework for prompt corrective action, the Bank and Company must meet specific 
capital guidelines that involve quantitative measures of the Bank and Company’s assets and liabilities, and certain off-balance-sheet items as calculated under regulatory 
accounting practices. The Bank and Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk 
weightings and other factors. 

Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Company to maintain minimum amounts and ratios (set forth 
in the table below) of total and Tier 1 capital (as defined in the regulation) to risk-weighted assets (as defined) and Tier 1 capital (as defined) to average assets (as 
defined). Management believes, as of December 31, 2017, that the Bank and the Company meet all capital adequacy requirements to which they are subject. 

The Basel Committee has issued capital standards entitled “Basel III: A global framework for more resilient banks and banking systems” (Basel III). The Federal Reserve 
has finalized its rule implementing the Basel III regulatory capital framework. The rule was effective in January 2015 and sets the Basel III minimum Regulatory capital 
requirements. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Common Equity tier 1, tier 1 risk-based, and Tier 1 leverage 
To Be Well Capitalized
ratios as set forth in the table. There are no conditions or events since that notification that management believes would cause a change in the Bank’s categorization.

Based on the Company’s historical and current pre-tax earnings, management believes it is more likely than not that the Company will realize the deferred income 
tax asset existing at December 31, 2017, with the exception of a $108,000 valuation allowance on a charitable contribution carryforward that has a remaining 
carryforward period of 3-4 years. Management believes that existing net deductible temporary differences which give rise to the deferred tax asset will reverse during 
periods in which the Company generates net taxable income. In addition, gross deductible temporary differences are expected to reverse in periods during which 
offsetting gross taxable temporary differences are expected to reverse. Factors beyond management’s control, such as the general state of the economy and real 
estate values, can affect future levels of taxable income, and no assurance can be given that sufficient taxable income will be generated to fully absorb gross deductible 
temporary differences. 

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted. The majority of the provisions of the Tax Act takes effect on January 1, 2018. 
The Tax Act lowers the Company’s federal tax rate from 34% to 21%. The Company evaluated its deferred taxes at 21% as of the enactment date and recorded 
additional tax expense of $8,448,000. Also, for tax years beginning after December 31, 2017, the corporate Alternative Minimum Tax (“AMT”) has been repealed. 
For 2018 through 2021, the AMT credit carryforward can offset regular tax liability and is refundable in an amount equal to 50% (100% for 2021) of the excess of 
the minimum tax credit for the tax year over the amount of the credit allowable for the year against regular tax liability. Accordingly, the full amount of the alternative 
minimum tax credit carryforward will be recovered in tax years beginning before 2022. The Tax Act also contains other provisions that may affect the Company 
currently or in future years. Among these are changes to the deductibility of meals and entertainment, the deductibility of executive compensation, the dividend 
received deduction and net operating loss carryforwards.

The Company is in an Alternative Minimum Tax (“AMT”) credit position. As the AMT has been repealed and the existing credit is refundable, the AMT credit, totalling 
$14,001,000, has been reclassified to currently receivable. The Company and its subsidiaries file a consolidated federal tax return. The Company is subject to federal 
and state examinations for tax years after December 31, 2013. 

 17. Employee Benefits 

The Company has a Qualified Defined Benefit Pension Plan (the “Plan”), which had been offered to all employees reaching minimum age and service requirements. In 
2006, the Bank became a member of the Savings Bank Employees Retirement Association (“SBERA”) within which it then began maintaining the Qualified Defined 
Benefit Pension Plan. SBERA offers a common and collective trust as the underlying investment structure for its retirement plans. The target allocation mix for the 
common and collective trust portfolio calls for an equity-based investment deployment range of 40% to 64% of total portfolio assets. The remainder of the portfolio 
is allocated to fixed income securities with target range of 15% to 25% and other investments including global asset allocation and hedge funds from 25% to 41%. 

The Trustees of SBERA, through its Investment Committee, select investment managers for the common and collective trust portfolio. A professional investment 
advisory firm is retained by the Investment Committee to provide allocation analysis, performance measurement and to assist with manager searches. The overall 
investment objective is to diversify investments across a spectrum of investment types to limit risks from large market swings. The Company closed the plan to 
employees hired after March 31, 2006.

The measurement date for the Plan is December 31 for each year. The benefits expected to be paid in each year from 2018 to 2022 are $1,530,000, $1,569,000, 
$1,732,000, $1,832,000, and $1,988,000, respectively. The aggregate benefits expected to be paid in the five years from 2023 to 2027 are $11,531,000. 

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives 
the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1) and the lowest priority to unobservable inputs (level 3). 
Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs. The three levels of the fair value hierarchy under 
Topic 820 are described as follows:

LEVEL 1

Inputs to the valuation methodology are quoted market prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to 
access at the measurement date.

LEVEL 2

Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly, such as: quoted prices for similar 
assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other that quoted prices that are observable for 
the asset or liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has 
specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

LEVEL 3

Inputs that are unobservable inputs for the asset or liability.

Below is a description of the valuation methodologies used for assets measured at fair value.

Collective Funds

Valued at either the closing price reported on the active market on which the individual securities are traded or valued at the net asset value (NAV) of units of a 
collective trust. The NAV, as provided by the trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying 
investments held by the fund less its liabilities. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an 
amount different than the reported NAV. Participant transactions (purchases and sales) may occur daily. Were SBERA to initiate a full redemption of the collective 
trust, the investment advisor reserves the right to temporarily delay withdrawal from the trust in order to ensure that securities liquidations will be carried out in an 
orderly business manner.

Equity Securities

Valued at the closing price reported on the active market on which the individual securities are traded.

Mutual Funds

Valued at the daily closing price as reported by the fund. Mutual funds held open-end mutual funds that are registered with the U.S. Securities and Exchange 
Commission. The funds are required to publish their daily NAV and to transact at that price.

The mutual funds held are deemed to be actively traded.

Limited Partnerships and Hedge Funds

The funds are valued at NAV, without further adjustment, as calculated by the fund’s manager based upon the terms and conditions of the organization documents of 
the underlying investments, with further consideration to portfolio risks.

The following table sets forth by level, within the fair value hierarchy, the plan’s assets at fair value. Classification within the fair value hierarchy table is based upon the 
lowest level of any input that is significant to the fair value measurement:

This category includes investments in hedge funds that pursue multiple strategies to diversify risks and reduce volatility. Fund objectives are to seek above-average rates of return and long-term capital 
growth through investments, which are fund of funds with a diversified portfolio of private investment entities and/or separately managed accounts managed by investment managers or achieve superior 
risk-adjusted capital appreciation over the long-term, generally through an investment, which invests in private investment funds and discretional managed accounts, structured notes, swaps or other similar 
(2) 
products. The fair values of the investments in this category have been determined using the net asset value per share of the fund(s).

This category has an investment strategy to pursue a hybrid absolute return via portfolio managers, secondaries, and co-investments with a flexible and opportunistic mandate tactically allocating capital 
to look to capitalize on market dislocations and inefficiencies. The opportunities are expected to fall within the following strategies: Niche Alternatives and Private Credit and Hedge Fund secondaries. The fair 
value of the investments in this category have been determined using the last sales price, for listed securities, and in accordance with the agreement terms for portfolio-managed investments, notes, swaps, 
(3) 
and other similar products.

The Fund’s investment objective is to invest in highly attractive, select investment opportunities by maintaining investments through private investment entities and/or separately managed accounts (each, 
an Investment or a Portfolio and collectively, the Investments or the Portfolios) with investment management professionals (each a Manager and collectively, the Managers) specializing in various alternative 
investment strategies. The Managers have broad investment experience and the ability to leverage their existing relationships with corporate management teams, investment banks and other institutions to 
gain access to certain investment opportunities. As such, the Manager is presented with “best idea” investment opportunities, typically in asset classes where market dislocations or other events have created 
attractive investment opportunities. The Managers are not restricted in the investment strategies that they may employ across different asset classes and regions. The Manager anticipates that any number of 
strategies will be eligible for consideration for investment by the Fund and the Fund reserves the right to invest in any particular strategy or asset class it deems appropriate.

ASSET ALLOCATION

SBERA offers a common and collective trust as the underlying investment structure for its retirement plans. The target allocation mix for the common and collective 
trust portfolio calls for an equity-based investment deployment range of 40% to 64% of total portfolio assets. The remainder of the portfolio is allocated to fixed 
income securities with a target range of 15% to 25% and other investments including global asset allocation and hedge funds from 25% to 41%.

The Trustees of SBERA, through the Association’s Investment Committee, select investment managers for the common and collective trust portfolio. A professional 
investment advisory firm is retained by the Investment Committee to provide allocation analysis, performance measurement and to assist with manager searches. The 
overall investment objective is to diversify investments across a spectrum of investment types to limit risks from large market swings.

The Company has a Supplemental Executive Insurance/Retirement Plan (the Supplemental Plan), which is limited to certain officers and employees of the Company. 
The Supplemental Plan is voluntary. Under the Supplemental Plan, each participant will receive a retirement benefit based on compensation and length of service. Life 
insurance policies, which are owned by the Company, are purchased covering the lives of each participant. 

The benefits expected to be paid in each year from 2018 to 2022 are $2,096,000, $2,068,000, $2,002,000, $1,939,000 and $1,966,000, respectively. The 
aggregate benefits expected to be paid in the five years from 2023 to 2027 are $13,107,000.

Assumptions for the expected return on plan assets and discount rates in the 
Company’s Plan and Supplemental Plan are periodically reviewed. As part of 
the review, management in consultation with independent consulting actuaries 
performs an analysis of expected returns based on the plan’s asset allocation. 
This forecast reflects the Company’s and actuarial firm’s expected return on 
plan assets for each significant asset class or economic indicator. The range of 
returns developed relies on forecasts and on broad market historical benchmarks 
for expected return, correlation and volatility for each asset class. Also, as a part 
of the review, the Company’s management in consultation with independent 
consulting actuaries performs an analysis of discount rates based on expected 
returns of high-grade fixed income debt securities. 

Effective January 1, 2016, the Company changed its estimate of the service and 
interest components of the net periodic benefit cost. Previously, the Company 
estimated the service and interest cost components utilizing a single weighted-
average discount rate derived from the yield curve used to measure the benefit 
obligation. The new estimate utilizes a full yield curve approach in the estimation 
of these components by applying the specific spot rates along the yield curve 
used in the determination of the benefit obligation to their underlying projected 
cash flows. The new estimate provided a more precise measurement of service 
and interests costs by improving the correlation between projected benefit 
cash flows and their corresponding spot rates. The change does not affect the 
measurement of the Company’s benefit obligations and it is accounted for as 
a change in accounting estimate, which is applied prospectively. For 2016, the 
change in estimate reduced periodic plan cost by $859,000 compared to the 
prior estimate. Mortality assumptions are based on the RP 2015 Mortality 
Table projected with Scale MP 2016. 

The Company offers a 401(k) defined contribution plan for all employees 
reaching minimum age and service requirements. The plan is voluntary and 
employee contributions are matched by the Company at a rate of 33.3% for the 
first 6% of compensation contributed by each employee. The Company’s match 
totaled $445,000 for 2017, $418,000 for 2016 and $403,000 for 2015. 
Administrative costs associated with the plan are absorbed by the Company. 

The Company has a cash incentive plan that is designed to reward our 
executives and officers for the achievement of annual financial performance goals 
of the Company as well as business line, department and individual performance. 
The plan supports the philosophy that management be measured for their 
performance as a team in the attainment of these goals. Discretionary bonus 
expense amounted to $1,859,000, $1,418,000 and $1,178,000 in 2017, 
2016, and 2015, respectively. 

The Company does not offer any postretirement programs other than pensions.

 18. Commitments and Contingencies 

A number of legal claims against the Company arising in the normal course of 
business were outstanding at December 31, 2017. Management, after reviewing 
these claims with legal counsel, is of the opinion that their resolution will not 
have a material adverse effect on the Company’s consolidated financial position 
or results of operations.

On September 7, 2017, Crimson Galeria Limited Partnership, Raj & Raj, LLC, 
Harvard Square Holdings LLC, and Charles River Holdings LLC (collectively, 
the “Plaintiffs”) filed suit in the United States District Court for the District 
of Massachusetts against the Attorney General of the Commonwealth of 
Massachusetts, the Massachusetts Department of Public Health, the City of 
Cambridge, the Town of Georgetown, as well as against the Bank, Healthy 
Pharms, Inc., (“Healthy Pharms”), Timbuktu Real Estate, LLC, Paul Overgaag, 
Nathaniel Averill, 4Front Advisors, LLC, 4Front Holdings LLC, Kristopher T. 
Krane, 3 Brothers Real Estate, LLC, Red Line Management, LLC, unspecified 
insurance providers to certain Plaintiffs, Tomolly, Inc., and (collectively, the 
“Defendants”).

The Plaintiffs allege that they own property in Cambridge, MA, and claim that 
the value and use of their property will be impaired by Healthy Pharms decision 
to open a registered medicinal marijuana dispensary in abutting or nearby 
situated property. The Plaintiffs further allege that the Bank has a banking 
relationship with Healthy Pharms and that, by entering into such relationship, 
the Bank conspired with Healthy Pharms to violate the Racketeer Influenced 
and Corrupt Organizations Act, 18 U.S.C. § 1961 et seq. The Plaintiffs seek 
unspecified treble damages, and attorney’s costs and fees, as well as injunctive 
and declaratory relief.

The Company believes that the claims and allegations against the Bank set forth 
in the complaint are without merit, and the Company and the Bank intend to 
vigorously defend against them.

On December 15, 2017, the Company filed a motion to dismiss the complaint; 
the plaintiffs filed an opposition brief, and the Company filed a reply in further 
support of its motion.

 19. Financial Instruments with Off-Balance-Sheet Risk 

The Company is party to financial instruments with off-balance-sheet risk in the 
normal course of business to meet the financing needs of its customers. 

These financial instruments primarily include commitments to originate and 
sell loans, standby letters of credit, unused lines of credit and unadvanced 
portions of construction loans. The instruments involve, to varying degrees, 
elements of credit and interest rate risk in excess of the amount recognized 
in the consolidated balance sheet. The contract or notional amounts of those 
instruments reflect the extent of involvement the Company has in these 
particular classes of financial instruments. 

The Company’s exposure to credit loss in the event of nonperformance by the 
other party to the financial instrument for loan commitments, standby letters 
of credit and unadvanced portions of construction loans is represented by the 
contractual amount of those instruments. The Company uses the same credit 
policies in making commitments and conditional obligations as it does for on-
Contract or Notional Amount 
balance-sheet instruments. Financial instruments with off-balance-sheet risk at 
December 31 are as follows:

Commitments to originate loans, unadvanced portions of construction loans, 
unused lines of credit and unused letters of credit are generally agreements to 
lend to a customer, provided there is no violation of any condition established 
in the contract. Commitments generally have fixed expiration dates or other 
termination clauses and may require payment of a fee. Since many of the 
commitments are expected to expire without being drawn upon, the total 
commitment amounts do not necessarily represent future cash requirements. 
The Company evaluates each customer’s creditworthiness on a case-by-case 
basis. The amount of collateral obtained, if deemed necessary by the Company 
upon extension of credit, is based on management’s credit evaluation of 
the borrower. 

Standby letters of credit are conditional commitments issued by the Company 
to guarantee the performance by a customer to a third party. The credit risk 
involved in issuing letters of credit is essentially the same as that involved in 
extending loan facilities to customers.

 21. Fair Values of Financial Instruments 

The following methods and assumptions were used by the Company in 
estimating fair values of its financial instruments. Excluded from this disclosure 
are all non-financial instruments. Accordingly, the aggregate fair value amounts 
presented do not represent the underlying value of the Company. 

The assumptions used below are expected to approximate those that market 
participants would use in valuing these financial instruments. 

Fair value estimates are made at a specific point in time, based on available 
market information and judgments about the financial instrument, including 
estimates of timing, amount of expected future cash flows and the credit 
standing of the issuer. Such estimates do not consider the tax impact of the 
realization of unrealized gains or losses. In some cases, the fair value estimates 
cannot be substantiated by comparison to independent markets. In addition, 
the disclosed fair value may not be realized in the immediate settlement of the 
financial instrument. Care should be exercised in deriving conclusions about our 
business, its value or financial position based on the fair value information of 
financial instruments presented below. 

SECURITIES HELD-TO-MATURITY 

The fair values of these securities were based on quoted market prices, where 
available, as provided by third-party investment portfolio pricing vendors. If 
quoted market prices were not available, fair values provided by the vendors 
were based on quoted market prices of comparable instruments in active markets 
and/or based on a matrix pricing methodology which employs The Bond Market 
Association’s standard calculations for cash flow and price/yield analysis, live 
benchmark bond pricing and terms/condition data available from major pricing 
sources. Management regards the inputs and methods used by third party 
pricing vendors to be “Level 2 inputs and methods” as defined in the “fair value 
hierarchy” provided by FASB. 

LOANS 

For variable-rate loans, that reprice frequently and with no significant change 
in credit risk, fair values are based on carrying amounts. The fair value of other 
loans is estimated using discounted cash flow analysis, based on interest rates 
currently being offered for loans with similar terms to borrowers of similar credit 
quality. Incremental credit risk for nonperforming loans has been considered. 

TIME DEPOSITS 

The fair value of time deposits was estimated using a discounted cash flow 
approach that applies prevailing market interest rates for similar maturity 
instruments. The fair values of the Company’s time deposit liabilities do not 
take into consideration the value of the Company’s long-term relationships with 
depositors, which may have significant value. 

OTHER BORROWED FUNDS 

The fair value of other borrowed funds is based on the discounted value of 
contractual cash flows. The discount rate used is estimated based on the rates 
currently offered for other borrowed funds of similar remaining maturities. 

SUBORDINATED DEBENTURES 

The fair value of subordinated debentures is based on the discounted value 
of contractual cash flows. The discount rate used is estimated based on 
the rates currently offered for other subordinated debentures of similar 
remaining maturities. 

The following presents (in thousands) the carrying amount, estimated fair value, 
and placement in the fair value hierarchy of the Company’s financial instruments 
as of December 31, 2017 and December 31, 2016. This table excludes 
financial instruments for which the carrying amount approximates fair value. 
Financial assets for which the fair value approximates carrying value include cash 
and cash equivalents, short-term investments, FHLBB stock and accrued interest 
receivable. Financial liabilities for which the fair value approximates carrying 
value include non-maturity deposits, short-term borrowings and accrued 
interest payable.

LIMITATIONS 

Fair value estimates are made at a specific point in time, based on relevant market information and information about the type of financial instrument. These estimates 
do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular financial instrument. Because no 
active market exists for some of the Bank’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, cash flows, 
current economic conditions, risk characteristics and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant 
judgment and therefore cannot be determined with precision. Changes in assumptions and changes in the loan, debt and interest rate markets could significantly affect 
the estimates. Further, the income tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates 
and have not been considered.

The Board of Directors and Stockholders  
Century Bancorp, Inc.: 

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Century Bancorp, Inc. and its subsidiary (the “Company”) as of December 31, 2017 and 2016, 
the related consolidated statements of income, comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period 
ended December 31, 2017, and the related notes, collectively, the “consolidated financial statements”. In our opinion, the consolidated financial statements present 
fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each 
of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal 
control over financial reporting as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission, and our report dated March 15, 2018 expressed an unqualified opinion on the effectiveness of the 
Company’s internal control over financial reporting. 

Basis for Opinion 

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated 
financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to 
assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also 
included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated 
financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 1982.

The Board of Directors and Stockholders  
Century Bancorp, Inc.: 

Opinion on Internal Control Over Financial Reporting

We have audited Century Bancorp, Inc. and its subsidiary’s (the “Company”) internal control over financial reporting as of December 31, 2017, based on criteria 
established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, 
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in 
Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.   

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance 
sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity, 
and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes, collectively, the consolidated financial statements, and 
our report dated March 15, 2018 expressed an unqualified opinion on those consolidated financial statements. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal 
control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an 
opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to 
be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the 
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial 
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions 
and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance 
with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of 
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with 
the policies or procedures may deteriorate.

CENTURY BANCORP, INC. 

400 Mystic Avenue 
Medford, Massachusetts 02155 

We, together with the other members of executive management of Century Bancorp, Inc. and our subsidiary (the “Company”), are responsible for establishing and 
maintaining adequate internal control over financial reporting. The Company’s internal control system was designed to provide reasonable assurance to the Company’s 
management and board of directors regarding the preparation and fair presentation of published financial statements. 

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only 
reasonable assurance with respect to financial statement preparation and presentation. 

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this 
assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated 
Framework (2013). Based on our assessment, we believe that, as of December 31, 2017, the Company’s internal control over financial reporting is effective based on 
those criteria. 

The Company’s independent registered public accounting firm has issued an audit report on the effectiveness of the Company’s internal control over financial 
reporting. Their report appears on page 55.
