2016 Annual Report

Outperformance 

A year of outdoing ourselves.

2 0 1 6   A N N U A L   R E P O R T

Chairman’s Message

I turned 90 years young in 2016 and continued to accomplish many goals, including publishing my autobiography 
titled “Character Counts.” I used the book to reflect on my past and share life lessons with my family, associates 
and friends. I’ve seen the business of banking transform over the course of my career. Working in my father’s 
furniture store taught me that my generation, the “Greatest Generation,” made their decisions based on service, 
honesty and convenience. If you provided one family member with great service they referred others to our store. 
My generation wanted this same convenience and service with their banking too. 

When I founded Century, banks were confined to a single community. I recognized the need for a state-chartered 
commercial bank in Somerville but I didn’t want to limit my customer base to a single community. I knew a major 
highway, Route 93, was being planned that would funnel traffic from the communities north of Boston onto 
Mystic Avenue in Somerville. I knew exactly where our first branch needed to be located for optimal visibility. 
During my generation, the laws changed to enable banks to expand from cities to counties, to the entire state 
and then nationally. When I opened our Malden branch, I introduced free checking and numerous other products 
that appealed to the public. We also expanded our operating hours to include Saturday. Customers welcomed 
these changes, but other local bankers were furious with me because they were used to closing on Wednesday 
afternoons and Saturdays. They felt I was being disruptive by focusing on what the customers desired. None of 
these banks are in existence today; they have all closed or merged.

Today’s generation banks from anywhere, at any time. Weekly trips to the bank to make deposits are no 
longer routine – deposits are made by taking pictures from mobile phones. Century Bank’s adaption of new 
technology has enabled us to compete with the largest international banks. Even with all of these changes, 
brick-and-mortar branches still matter. Technology and generational tastes change but the physical branch still 
remains an important aspect of where to bank. We’ve responded by shrinking the branch size and expanding 
our staff skills to provide the full breath of banking services. Brands that once were the gold standard of retailing, 
like Sears, are struggling to find their place today. Retailers have been slow to evolve their model to compete 
with online behemoths like Amazon. Generations change and business must evolve with them. 

No matter what happens, banking remains a business of trust. Our clients and communities trust us with their 
homes, life savings and businesses. They expect us to do the right thing. Yet we continue to read about bankers 
who take advantage of this trust for their own gain. I was disheartened, but not surprised, to recently learn 
another giant bank took advantage of their clients’ trust by charging them fees for products and services they 
never requested. The fraud was ingrained in their organizational culture. Once discovered by the regulators they 
paid big fines but I have my doubts these indiscretions won’t reoccur even with the new leadership. Century’s 
culture would never tolerate this behavior which is why I’m proud to partner with the more than 400 Associates 
in the business I founded almost 50 years ago. My son and daughter, Barry and Linda, are the leaders for the 
next generation and will carry on the principles my father taught me. We are the largest family-run bank in 
New England, a rare characteristic in today’s financial industry. I am confident we will continue to deliver 
outperformance in our financial growth and risk decisions. I’m still excited and fascinated by the business of 
banking and intend to actively lead Century Bank as long as my health allows. I look forward to prospering 
together in 2017 and the years ahead. I thank you for your continued support and loyalty. 

Our Family’s Bank. And Yours.

Marshall M. Sloane, Founder and Chairman

President’s Message

Dear Fellow Shareholders:

2016 is the seventh consecutive record year for Century Bank. Century has been profitable in virtually every one of 
its 48 years, and has paid an uninterrupted dividend for 40 years. We continue to outperform in nearly all matters 
financial and strategic. Capital, assets, deposits, earnings, and loans all again reached record year-end levels. We 
wish to make particular note of our loan growth in 2016, $192 million, or 11%, to a total of $1.9 billion. We have 
achieved consistent and meaningful loan growth, without taking any speculative real estate project risk, a very 
different strategy than virtually all of our peers. We ended 2016 at $4.5 billion in assets, growth of 13% and 
$24.5 million of annual earnings, an increase of 6.6%. Our stock rose an astounding 38% to $60 at year-end; 
a three-year cumulative total return of 87% and a five-year cumulative total return of 127%. All three principal 
business units performed extremely well in 2016.

It is no exaggeration to say that the regulatory, fiscal, and macroeconomic environment all changed on 
November 8. The post-election world, despite enormous controversy, appears to be constructive for our future.

Our Family’s Bank. And Yours.

Our Founder and Chairman, Marshall M. Sloane, is in his 91st year, making him one of the 3 most senior working 
bank Chairmen in the country. He comes to work every day, adding his unparalleled market knowledge and industry 
experience to our decision making process. 

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 outperformance that have contributed to our success.

Outperforming 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. 

Outperforming in Consistency of Net Earnings Growth 
and Return on Equity

Net income grew by 6.6% to a record $24.5 million, or $4.41 per Class A share 
diluted, for the year ended December 31, 2016, as compared to net income of 
$23.0 million, or $4.13 per Class A share diluted for 2015. Century’s return on 
average equity (ROE) was 10.80%, for 2016, as compared to 2015’s 11.26%. 
Our ROE remains within the top 15% of our regional peer group. 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 double digit ROE, the 
share price will follow over time. It is why we believe Standard and Poor’s 
continues for the second year to rate Century’s shares an “A” and a “Buy.” 

In addition, our efficiency ratio of overhead to revenue, the key metric of 
comparative non-interest expense decreased (favorable) from 64% in 2015 to 
63% in 2016. We watch our expenses carefully.

Significant Asset Growth 

Outperforming Supports 
Capital Adequacy 

Total equity was $240.0 million on 
December 31, 2016, an increase 
of $25.5 million or 11.9% from 
$214.5 million on December 31, 
2015. Book value per share 
increased to $43.11 at December 31, 
2016, up by $4.58 from $38.53 
at December 31, 2015. Century is 
“well capitalized” by all regulatory 
standards, and we have passed all 
“Basel III” requirements through 
organic capital generation from 
earnings.

Total assets grew 13% to a record of 
$4.5 billion on December 31, 2016, 
up from $3.9 billion on December 
31, 2015, an increase of $515 
million. We experienced significant 
growth in 2016 for all three of 
our business lines: consumer, 
business, and institutional 
services. Our depositor confidence is 
pronounced and predicated on our 
consistent growth of earnings and 
assets. 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 nine S&P “A” rated banks 
in America, and one of only two in 
Massachusetts, is a strong external 
contributing confidence factor.

 $1.92

       Billion in Total Loans

Outperforming Grows 
Our Loan Portfolio

Our unique loan portfolio strategy 
continues to work really well. Total 
loans grew by $192 million or 11% 
to a record $1.92 billion on December 
31, 2016; our largest loan portfolio 
ever, and a loan to deposit ratio of 
53%. Non-performing assets fell 
again from the previous year to $1.1 
million, down from $2.3 million, a 
continued minimal number for a 
portfolio of our size. The education 
and healthcare sectors anchor our 
loan growth, increasing some 10% 
as 2016 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 Greater Boston’s colleges 
and universities validates 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 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 every loan.

2016 was a productive year in which 
we closed $93 million in residential 
first mortgages, and $148 million in 
home equity loans. We extended 
188 energy conservation loans 
through the Mass Save loan program, 
which helped us do our part for 
conservation while originating many 
new long term relationships.

Outperformance in Our Branch System

In 2016 we decided to relocate our “downtown” Wellesley branch to 258 
Washington Street in Wellesley Hills at Route 9. It is an improved location with 
reserved parking in front, and we opened in December 2016. It has already met 
with a warm reception from the community and deposits have grown. We will be 
very discerning in the search for branch #28. We are on the lookout for further 
high visibility market-extending locations, small size and manageable cost is 
paramount.

We approved in 2016 a regionally managed branch system, dividing by geography, 
and placing supervision and mentoring much closer to the line. It worked 
skillfully in 2016 along with our superb staff, as branch deposits grew by 20%.

Outperformance 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 37 million check and payment items in 2016, 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. 

Let me quote one truly satisfied long-duration government client who wrote to 
us, “Providing quality customer service has become a lost art as companies 
today are strictly profit driven. There is no business that we are affiliated with 
that sets a higher standard than Century Bank…it remains a first class 
organization in every respect.” I truly could not have said it any better. We will do 
our utmost to insure it is always true.

Outperformance in Wealth Management

2016 was the second full year of our rechristened wealth management function. 
Our assets under management grew 31.6% to over $78 million in 2016. 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. In 2016 
we also migrated to a much enhanced custodial and trading platform that 
improves reporting and reduces client expenses.

Outperformance 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 and on 
radio, 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. 

Outperformance 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 2016. We are constantly monitoring our systems reliability, and 
when customers encounter problems at night or on weekends we’re always 
reachable. Even New Year’s Eve when a client with a withdrawal problem 
reached me at 1 AM, we took action to rectify the issue within an hour.

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.

Outperformance 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 utilizing these 
resources 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.

Outperformance of 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. We 
certainly hope in 2017 that the 
divisions in our society will mend, 
and all Americans will focus on the 
elements of our commonality, rather 
than our differences.

Thank you to our shareholders, our 
clients, our associates, and our 
communities, for their confidence 
and relationships. We will endeavor 
to make 2017 another year of 
outperformance through our 
diligence and resourcefulness.

Gratefully,

Barry R. Sloane

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 

The financial services industry continues to face challenges in the aftermath 
of the recent national and global economic crisis. Since June 2009, the U.S. 
economy has been recovering from the most severe recession and financial crisis 
since the Great Depression. There have been improvements in private sector 
employment, industrial production and U.S. exports; nevertheless, the pace 
of economic recovery has been slow. Financial markets have improved since 
the depths of the crisis but are still unsettled and volatile. There is continued 
concern about the U.S. economic outlook. 

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 

3

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. 

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, 
2016, the Company had total assets of $4.5 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 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 
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 $24,534,000 for the year ended 
December 31, 2016, compared with net income of $23,021,000 for the year 
ended December 31, 2015, and net income of $21,860,000 for the year 
ended December 31, 2014. Class A diluted earnings per share were $4.41 in 
2016, compared to $4.13 in 2015 and $3.93 in 2014.

The net interest margin declined slightly throughout 2014 and the first quarter 
of 2015. During the second and third quarter 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.

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 
4.00 %
positively impact the net interest margin.

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 2015 and 2016, short-term rates increased 
slightly more than longer-term rates resulting in a slight flattening of the 
yield curve. 

During 2016 and 2015, 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 2015 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, 2015 and 2014, 
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. 

Total assets were $4,462,608,000 at December 31, 2016, an increase of 
13.1% from total assets of $3,947,441,000 at December 31, 2015. 

On December 31, 2016, stockholders’ equity totaled $240,041,000, 
compared with $214,544,000 on December 31, 2015. Book value per 
share increased to $43.11 at December 31, 2016, from $38.53 on 
December 31, 2015. 

During December 2013, the Company entered into a lease agreement to 
open a branch located in Woburn, Massachusetts. The branch opened on 
November 3, 2014. 

During March 2014, the Company entered into a lease agreement to open a 
branch located on Boylston Street in Boston, Massachusetts. This property is 
leased from an entity affiliated with Marshall M. Sloane, Chairman of the Board 
of the Company. This agreement was approved by the Board of Directors in the 
absence of the Chairman of the Board. The branch opened on April 22, 2015. 
The deposits from the Kenmore Square, Boston, Massachusetts branch, which 
closed on September 30, 2014, were moved to the new Boylston Street branch. 
The Kenmore Square landlord did not renew the existing lease during 2014.

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.

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 impairment of investment securities, allowance for loan 
losses and income taxes to be its critical accounting policies. There have been 
no significant changes in the methods or assumptions used in the investment 
securities accounting policy that require material estimates and assumptions. 
There was a methodology enhancement to the allowance for loan losses policy. 
This enhancement is described below. 

Impaired Investment Securities 

Management evaluates securities for other-than-temporary impairment (“OTTI”) 
on a periodic basis. Factors considered in determining whether an impairment is 
OTTI include: (1) the length of time and the extent to which the fair value has 
been less than amortized cost, (2) projected future cash flows, (3) the financial 
condition and near-term prospects of the issuers and (4) the intent and ability 
of the Company to hold the investment for a period of time sufficient to allow 
for any anticipated recovery in fair value. The Company records an OTTI loss in 
an amount equal to the entire difference between the fair value and amortized 
cost if (1) the Company intends to sell an impaired investment security, (2) it 
is more likely than not that the Company will be required to sell the investment 
security before its amortized costs or (3) for debt securities, the present value 
of expected future cash flows is not sufficient to recover the entire amortized 
cost basis. If an investment security is determined to be OTTI but the Company 
does not intend to sell the investment security, only the credit portion of the 
estimated loss is recognized in earnings, with the non-credit portion of the loss 
recognized in other comprehensive income. 

The Company does not intend to sell any of its debt securities with an 
unrealized loss, 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, which may be maturity.

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 2015, the Company enhanced its approach to the development of the historical loss factors and qualitative factors used on certain loan portfolios. The 
enhancement is described within the Allowance for Loan Losses section of “Management’s Discussion and Analysis of Results of Operations and Financial Condition”. 
During 2016, 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 and the existence of prior years’ taxable income 
to which refund claims could be carried back. 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. 

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, 2016 totaled $499,297,000 and included gross unrealized gains of $555,000 and gross 
unrealized losses of $1,478,000. A year earlier, the fair value of securities available-for-sale was $404,623,000 including gross unrealized gains of $979,000 and 
gross unrealized losses of $1,333,000. In 2016, the Company recognized gains of $52,000 on the sale of available-for-sale securities. In 2015 and 2014, the 
Company recognized gains of $289,000 and $450,000, 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, 2016 are carried at their amortized cost of $1,653,986,000. A year earlier, securities 
held-to-maturity totaled $1,438,903,000. In 2016 the company recognized gains of $12,000 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. In 
2015, the Company recognized gains of $305,000. In 2014 the Company did not recognize any gains on sales of held-to-maturity securities.

During the third quarter of 2013, $987,037,000 of securities available-for-sale with unrealized losses of $25,333,000 were transferred to securities held-to-
maturity. This was done in response to rising interest rates and an assessment of liquidity needs. 

The following table sets forth the fair value and percentage distribution of securities available-for-sale at the dates indicated.

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, 2016. 

Securities available-for-sale totaling $164,876,000, or 3.7% 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, 2016 and 2015, the Bank had no investments in obligations of individual states, counties, municipalities or nongovernment corporate entities which 
exceeded 10% of stockholders’ equity. 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 2016 and 2015. In 2015, sales of securities totaling $51,551,000 in gross proceeds resulted in net realized 
gains of $594,000. In 2014, sales of securities totaling $40,285,000 in gross proceeds resulted in net realized gains of $450,000.

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 2015, and 2016, the Company increased its lending activities to these 
types of organizations. The percentage of these types of organizations to total C&I loans has increased to 81% at December 31, 2016, compared to 76% at 
December 31, 2015.

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 has increased its lending activities 
to municipalities.

Residential real estate (1–4 family) includes two categories of loans. Included in residential real estate are approximately $28,464,000 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, 2016, the Company was obligated to advance a total of $22,049,000 to complete projects 
under construction.

At December 31, 2016, 2015, 2014, 2013, and 2012, impaired loans had specific reserves of $173,000, $250,000, $904,000, $1,019,000, and 
$1,732,000 respectively. 

The Company was servicing mortgage loans sold to others without recourse of approximately $229,730,000, $185,299,000, $143,696,000, $109,301,000, and 
$26,786,000 at December 31, 2016, 2015, 2014, 2013, and 2012, respectively. The Company had no loans held for sale at December 31, 2016, December 31, 
2015, December 31, 2014, December 31, 2013, and $9,378,000 at December 31, 2012.

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 $1,629,000 at December 31, 2016, $1,305,000 at December 31, 2015, $941,000 at 
December 31, 2014, $703,000 for December 31, 2013, and $137,000 for December 31, 2012.

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 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. Nonaccrual loans decreased during 2013 primarily as a result of a 
charge-off of a construction loan and a decrease in residential real estate nonperforming loans. 

The Company continues to monitor closely $35,583,000 and $11,203,000 at December 31, 2016 and 2015, 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, 2016, 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 2013, 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 a lower level of charge-off activity combined with changes in the portfolio composition and related methodology enhancements to 
address these changes.

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.

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 
2015 
economic conditions. Although the allowance is allocated between categories, the entire allowance is available to absorb losses attributable to all loan categories. At

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.”

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 $293,000,000, a decrease of $75,000,000 from the prior year. The Bank’s remaining term borrowing capacity at the FHLBB at December 31, 2016, 
was approximately $239,163,000. 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 
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 
$182,280,000, a decrease of $15,570,000 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 7.3% in 2016 to $86,999,000, compared with $81,099,000 in 2015. 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 increase in net interest income for 2015 was mainly due to an 
8.3% 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 decreased to 2.12% in 2016 from 2.18% in 2015 and decreased from 2.22% in 2014. The decrease in the net interest margin, for 
2016 and 2015, 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 $416,000, $945,000 and $693,000 respectively, of prepayment penalties, which 
are included in interest income on loans, for 2016, 2015, and 2014, 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 $4,105,161,000 in 2016, an increase of $381,682,000 or 10.3% from the average in 2015, which was 8.3% higher than the average 
in 2014. Total average securities, including securities available-for-sale and securities held-to-maturity, were $2,031,686,000, a decrease of 1.3% from the average 
in 2015. The decrease in securities volume was mainly attributable to a decrease in taxable securities. An increase in short term rates resulted in slightly higher 
securities income, which increased 0.8% to $38,113,000 on a fully tax equivalent basis. Total average loans increased 21.9% to $1,838,136,000 after increasing 
$199,658,000 in 2015. The primary reason for the increase in loans was due in large part to an increase in tax-exempt lending as well as residential second mortgage 
lending. The increase in loan volume resulted in higher loan income. Loan income increased by 11.5% or $7,269,000 to $70,267,000. Total loan income was 
$59,996,000 in 2014. Prepayment penalties collected were $416,000, $945,000, and $693,000 for 2016, 2015, and 2014, respectively.

The Company’s sources of funds include deposits and borrowed funds. On average, deposits increased 13.5%, or $408,321,000, in 2016 after increasing by 5.1%, 
or $146,996,000, in 2015. Deposits increased in 2016, primarily as a result of increases in demand deposits, savings, money market, NOW accounts, and time 
deposits. Deposits increased in 2015, primarily as a result of increases in demand deposits, savings, money market, NOW accounts, and time deposits. Borrowed funds 
and subordinated debentures decreased by 6.2% in 2016, following an increase of 26.8% in 2015. 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 $16,134,000, and average retail repurchase 
agreements decreased by $22,320,000 in 2016. Interest expense totaled $22,617,000 in 2016, an increase of $2,483,000, or 12.3%, from 2015 when interest 
expense increased 5.2% from 2014. The increase in interest expense, for 2016, is primarily due to increases in the average balances of deposits offset, somewhat by a 
decrease in borrowed funds. The increase in interest expense, for 2015, is primarily due to increases in the average balances of deposits and borrowed funds.

Provision for Loan Losses

The provision for loan losses was $1,375,000 in 2016, compared with $200,000 in 2015 and $2,050,000 in 2014. 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 2016, primarily as a result of an increase in loan 
balances. The provision for loan losses decreased during 2015, primarily as a result of changes in the portfolio composition, related methodology enhancements 
to address these changes, as well as net recoveries being realized during the year. 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.

The allowance for loan losses was $24,406,000 at December 31, 2016, 
compared with $23,075,000 at December 31, 2015. Expressed as a 
percentage of outstanding loans at year-end, the allowance was 1.27% in 2016 
and 1.33% in 2015. The allowance for loan losses increased primarily as a 
result of an increase in loan balances. The ratio of allowance for loan losses as a 
percentage of outstanding loans at year-end decreased primarily as a result of 
changes in portfolio composition and lower historical loss rates.

Nonperforming loans, which include all non-accruing loans, totaled $1,084,000 
on December 31, 2016, compared with $2,336,000 on December 31, 2015. 
Nonperforming loans decreased primarily as a result of a decrease in consumer 
mortgage nonperforming loans. 

Other Operating Income 

During 2016, 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 2016 was $16,222,000, an increase of 
$229,000, or 1.4%, compared to 2015. This increase followed an increase 
of $722,000, or 4.7%, in 2015, compared to 2014. Included in other 
operating income are net gains on sales of securities of $64,000, $594,000 
and $450,000 in 2016, 2015 and 2014, respectively. Also included in other 
operating income are net gains on sales of mortgage loans of $1,331,000, 
$1,034,000 and $757,000 in 2016, 2015 and 2014, respectively. Service 
charge income, which continues to be a major source of other operating income, 
totaling $7,907,000 in 2016, increased $175,000 compared to 2015. This 
followed a decrease of $331,000 in 2015 compared to 2014. 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. The decrease in fees, in 2015, was mainly attributable to a 
decrease in overdraft fees and fees collected from processing activities; this was 
offset somewhat by an increase in debit card fees. Lockbox revenues totaled 
$3,164,000, down $47,000 in 2016 following an increase of $112,000 in 
2015. Other income totaled $3,441,000, up $399,000 in 2016 following an 
increase of $442,000 in 2015. 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. The increase in 2015 was 
primarily the result of increases in merchant and charge card sales royalties. 

Operating Expenses 

Total operating expenses were $64,757,000 in 2016, compared to 
$62,198,000 in 2015 and $56,730,000 in 2014.

Salaries and employee benefits expenses increased by $1,452,000 or 3.8% in 
2016, after increasing by 10.0% in 2015. The increase in 2016 was mainly 
attributable to merit increases in salaries, bonus accruals, pension costs and 

15

health insurance costs. The increase in 2015 was mainly attributable to increases 
in staff levels, merit increases in salaries, pension costs and health insurance costs.

Occupancy expense increased by $31,000, or 0.5%, in 2016, following an 
increase of $613,000, or 11.1%, in 2015. The increase in 2016 was primarily 
attributable to an increase in rent expense. The increase in 2015 was primarily 
attributable to an increase in rent expense, depreciation expense and building 
maintenance associated with branch expansion. 

Equipment expense increased by $219,000, or 8.3%, in 2016, following an 
increase of $297,000, or 12.8%, in 2015. The increase in 2016 was primarily 
attributable to an increase in depreciation expense. The increase in 2015 was 
primarily attributable to an increase in depreciation expense associated with 
branch expansion. 

FDIC assessments decreased by $250,000, or 11.6%, in 2016, following 
an increase of $182,000, or 9.2%, in 2015. FDIC assessments decreased in 
2016 mainly as a result of a decrease in the assessment rate. FDIC assessments 
increased in 2015 mainly as a result of deposit growth. 

Other operating expenses increased by $1,107,000 in 2016, which followed 
an $876,000 increase in 2015. The increase in 2016 was primarily attributable 
to an increase in marketing expenses, telephone expenses, software maintenance 
costs, contributions, and postage expenses. The increase in 2015 was primarily 
attributable to an increase in bank security, software maintenance costs, and 
legal expenses.

Provision for Income Taxes

Income tax expense was ($362,000) in 2016, $533,000 in 2015, and 
$866,000 in 2014. The effective tax rate was (1.5%) in 2016, 2.3% in 2015 
and 3.8% in 2014. The decrease in the effective tax rate for 2016 and 2015 was 
mainly attributable to an increase in tax-exempt interest income as a percentage 
of taxable income. The federal tax rate was 34% in 2016, 2015 and 2014. 

Market Risk and Asset Liability Management 

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 

(9.0)
(6.4)
(4.7)
(2.1)
0.8
(0.4)

(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 and Capital Resources 

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 $239,334,000 on December 31, 2016, compared with $223,957,000 on December 31, 2015. 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 $240,041,000 at December 31, 2016, compared with $214,544,000 at December 31, 2015. 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 amortization of the pension 
liability. This was offset, somewhat, by an increase in unrealized losses on securities available-for-sale. 

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-
2015
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  

2016  

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

  52,224 

$  5,638
4,936
  320,874
  11,589
  41,717

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 $44,000 and $51,000 for 2016 and 2015, 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, 2016 and 2015, 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 ’16Notes 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, 2016, 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, 2016.

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 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, 

24

Century Bancorp, Inc.  AR ’16Notes to Consolidated Financial Statementsupon periodic evaluation by management, further declines in the estimated 
fair value of properties have occurred. 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 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 

25

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 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. 

Century Bancorp, Inc.  AR ’16Notes to Consolidated Financial Statements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 
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, 2016. 

The Company uses the fair value method to account for stock options. There 
were no options granted during 2016 and 2015. 

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. 

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 ’16Notes to Consolidated Financial StatementsRECENT ACCOUNTING DEVELOPMENTS 

In May 2014, the Financial Accounting Standards Board (“FASB”) issued 
Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts 
with Customers (Topic 606). This ASU is intended to create a single source 
of revenue guidance which is more principles based than current revenue 
guidance. The guidance affects any entity that either enters into contracts 
with customers to transfer goods or services, or enters into contracts for the 
transfer of non-financial assets, unless those contracts are within the scope of 
other standards. In August 2015, the FASB issued ASU 2015-14, “Revenue 
from Contracts with Customers (Topic 606): Deferral of the Effective Date” to 
amend the effective date of ASU 2014-09. The amendments in ASU 2014-09 
are effective for annual and interim periods within fiscal years beginning after 
December 15, 2017. Earlier adoption is permitted only as of annual reporting 
periods beginning after December 15, 2016, including interim reporting periods 
within that reporting period. The FASB has since issued additional related ASUs 
amendments intended to clarify certain aspects and improve understanding 
of the implementation guidance of Topic 606 but do not change the core 
principles of the guidance in Topic 606. The effective date and transition 
requirements for the amendments are the same as the effective date and 
transition requirements of Topic 606. The Company is currently evaluating the 
potential impact of the ASU and its amendments on the Company’s financial 
statements and results of operations.

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 Company is 
currently assessing the applicability of this ASU and has not determined the 
impact, if any, as of December 31, 2016. 

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 is currently assessing the applicability of this ASU and 
has not determined the impact, if any, as of December 31, 2016. 

In March 2016, the FASB issued ASU 2016-07, Investments—Equity Method 
and Joint Ventures (Topic 323) Simplifying the Transition to the Equity Method 
of Accounting. This ASU requires that an entity that has an available-for-sale 
equity security that becomes qualified for the equity method of accounting 
recognize through earnings the unrealized holding gain or loss in accumulated 
other comprehensive income at the date the investment becomes qualified for 
use of the equity method. This ASU is effective for all entities for fiscal years, 
and interim periods within those fiscal years, beginning after December 15, 
2016. The effect of this update is not expected to have a material impact on the 
Company’s consolidated financial position.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock 
Compensation (Topic 718): Improvements to Employee Share-Based Payment 
Accounting. This ASU was issued as part of the FASB Simplification Initiative 
which intends to reduce the complexity of GAAP while improving usefulness to 
users. There are eight main items in this ASU that contribute to the simplification 
of share-based accounting. For public entities, this ASU is effective for the 
fiscal years beginning after December 15, 2016, including interim periods 

27

within those fiscal years. Early adoption is permitted. 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 currently assessing this ASU and has not determined the impact, if 
any, as of December 31, 2016. 

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 Company is currently assessing 
the applicability of this ASU and has not determined the impact, if any, as of 
December 31, 2016.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) 
Intra-Entity Transfers of Assets Other Than Inventory. This ASU was issued to 
improve the accounting for income tax consequences of intra-entity transfers 
of assets other than inventory. For public entities, this ASU is effective for the 
fiscal years beginning after December 15, 2017, including interim periods 
within those fiscal years. Early adoption is permitted. Management is currently 
assessing the applicability of this ASU and has not determined the impact, if any, 
as of December 31, 2016.

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810) 
Interests Held through Related Parties That Are under Common Control. The 
amendments of this ASU affect reporting entities that are required to evaluate 
whether they should consolidate a Variable Interest Entity within the Variable 
Interest Entities Subsections of Subtopic 810-10, Consolidation—Overall, in 
certain situations involving entities under common control. For public entities, 
this ASU is effective for the fiscal years beginning after December 15, 2016, 
including interim periods within those fiscal years. Early adoption is permitted. 
The effect of this update is not expected to have a material impact on the 
Company’s consolidated financial position.

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. Early adoption is permitted. 
Management is currently assessing the applicability of this ASU and has not 
determined the impact, if any, as of December 31, 2016.

Included in SBA Backed Securities and U.S. Government Agency and Sponsored Enterprises Mortgage-Backed Securities are securities at fair value pledged to secure 
public deposits and repurchase agreements amounting to $210,780,000 and $220,482,000 at December 31, 2016 and 2015, respectively. Also included in 
securities available-for-sale at fair value are securities pledged for borrowing at the Federal Home Loan Bank amounting to $53,396,000 and $20,056,000 at 
December 31, 2016 and 2015, respectively. The Company realized gains on sales of securities of $52,000, $289,000, and $450,000 from the proceeds of sales 
of available-for-sale securities of $2,376,000, $47,853,000, and $40,285,000 for the years ended December 31, 2016, 2015, and 2014, respectively.

The weighted average remaining life of investment securities available-for-sale at December 31, 2016, was 4.4 years. Included in the weighted average remaining life 
calculation at December 31, 2106, were $15,000,000 of US 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, $301,253,000 of the securities are floating rate or adjustable rate and reprice prior to maturity.

As of December 31, 2016 and December 31, 2015, 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, 2016 and December 31, 2015.

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 weighted average remaining life of investment securities held-to-maturity at December 31, 2016, was 4.5 years. Included in the weighted average remaining life 
calculation at December 31, 2016, were $59,745,000 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, $188,000 of the securities are floating rate or adjustable rate and reprice prior to maturity. 

As of December 31, 2016 and December 31, 2015, 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 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, 2016 and December 31, 2015. 

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. 

The following table shows the temporarily impaired securities of the Company’s held-to-maturity portfolio at December 31, 2016. 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. 
Temporarily Impaired Investments 
There are 194 and 16 securities that are temporarily impaired for less than 12 months and for 12 months or longer, respectively, out of a total of 375 holdings at

At December 31, 2016, and December 31, 2015, loans were carried net of discounts of $313,000 and $360,000, respectively. Net deferred fees included in loans 
at December 31, 2016, and December 31, 2015, were $641,000 and $988,000, respectively. 

The Company was servicing mortgage loans sold to others without recourse of approximately $229,730,000 and $185,299,000 at December 31, 2016, and 
December 31, 2015, respectively. The Company had no residential real estate loans held for sale at December 31, 2016 and December 31, 2015. The Company’s 
mortgage servicing rights totaled $1,629,000 and $1,305,000 at December 31, 2016 and December 31, 2015, respectively. 

As of December 31, 2016 and 2015, the Company’s recorded investment in impaired loans was $3,830,000 and $3,225,000, 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, 2016, there were $3,105,000 of impaired loans 
with a specific reserve of $173,000. At December 31, 2015, there were $3,051,000 of impaired loans with specific reserves of $250,000.

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.

Loans rated 1-3 (Pass) — Loans in this category are considered “pass” rated loans with low to average risk. 

Loans rated 4 (Monitor) — These loans represent classified loans that management is closely monitoring for credit quality. These loans have had or may have minor 
credit quality deterioration as of December 31, 2016. 

Loans rated 5 (Substandard) — Substandard loans represent classified loans that management is closely monitoring for credit quality. These loans have had more 
significant credit quality deterioration as of December 31, 2016. 

Loans rated 6 (Doubtful) — Doubtful loans represent classified loans that management is closely monitoring for credit quality. These loans had more significant credit 
quality deterioration as of December 31, 2016, and are doubtful for full collection. 

Impaired — Impaired loans represent classified loans that management is closely monitoring for credit quality. A loan is classified as impaired when it is probable that 
the Company will be unable to collect all amounts due.

IMPAIRED LOANS 

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 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 troubled debt restructurings occurring during the year ended December 31, 2015. Also, there were no commitments to lend additional funds to 
troubled debt restructuring borrowers. There were no troubled debt restructurings that subsequently defaulted during 2015 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 2016 for the 
estimated credit loss amounted to ($135,000). 

There were no transfers between level 1, 2 and 3 for the year ended December 31, 2016. There were no liabilities measured at fair value on a recurring or 
nonrecurring basis during the year ended December 31, 2016.

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 2016 for the 
estimated credit loss amounted to ($165,000).

There were no transfers between level 1 and 2 for the year ended December 31, 2015. There were no liabilities measured at fair value on a recurring or nonrecurring

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 the stock options discussed below. The dilutive effect of these stock options for 2016, 2015 and 2014 was an increase of 0, 0, and 1,447 
shares, 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, 2016 and December 31, 2015.

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, 2016, that the Bank and the Company meet all capital adequacy requirements to which they are subject. 

The Basel Committee has issued capital standards entitled “Base 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 
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, 2016, with the exception of a $108,000 valuation allowance on a charitable contribution carryforward that has a remaining 
carryforward period of four 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. The Company is in an Alternative Minimum Tax (“AMT”) credit position. The AMT credit is carried as a deferred asset and has an indefinite life. 
The Company’s intent is not to perpetually remain an AMT taxpayer and has potential tax planning strategies available which support the deferred AMT credit and, at 
this time, no valuation allowance is needed. The Company and its subsidiaries file a consolidated federal tax return. The Company is subject to federal examinations for 
tax years after December 31, 2013, and state examinations for the tax years after December 31, 2012. 

 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 20% to 36%. 

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 plan assets measured at fair value in Level 1 are based on quoted market prices in an active exchange market. 

LEVEL 2 

Plan assets measured at fair value in Level 2 are based on pricing models that consider standard input factors, such as observable market data, benchmark yields, 
interest rate volatilities, broker/dealer quotes, credit spreads and new issue data. 

LEVEL 3 

Plan assets measured at fair value in Level 3 are based on unobservable inputs, which includes SBERA’s assumptions and the best information available under the 
circumstance. Level 3 assets consist of hedge funds. The underlying assets are valued based upon quoted exchange prices, over-the-counter trades, bid/ask prices, 
relative value assessments based on market conditions, and other information, as available. Further adjustments may be made based on factors impacting liquidity. 

The asset or liability’s fair value measurement level within fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. 
Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. Below is a description of the valuation 
methodologies used for assets measured at fair value. 

The Trust reports bonds and other obligations, short-term investments and equity securities at fair values based on published quotations, Collective funds and hedge 
funds (Funds) are valued in accordance with valuations provided by such Funds, which generally value marketable securities at the last reported sales price on the 
valuation date and other investments at fair value, as determined by each Fund’s manager. 

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future values. Furthermore, 
although the Trust believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies to determine the 
fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The performance of the plan assets is dependent upon general market conditions and specific conditions related to the issuers of the underlying securities. 

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 2017 to 2021 are $2,031,000, $1,990,000, $1,964,000, $1,906,000 and $1,830,000, respectively. The

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.

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 $418,000 for 2016, $403,000 for 2015 and $346,000 for 2014. 
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 $1,418,000, $1,178,000 and $1,434,000 in 2016, 
2015, and 2014, 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, 2016. 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.

 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. 

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 
Year ended December 31, 
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, 2016 and December 31, 2015. 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.

Independent Registered Public Accounting Firm 
Two Financial Center  
60 South Street  
Boston, Massachusetts 02111-2759 

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

We have audited the accompanying consolidated balance sheets of Century Bancorp, Inc. and its subsidiary as of December 31, 2016 and 2015 and 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, 2016. 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 conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan 
and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our 
opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Century Bancorp, Inc. and 
its subsidiary as of December 31, 2016 and 2015 and the results of their operations and their cash flows for each of the years in the three-year period ended 
December 31, 2016, 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), Century Bancorp, Inc.’s internal control 
over financial reporting as of December 31, 2016, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 15, 2017, expressed an unqualified opinion on the effectiveness of the 
Company’s internal control over financial reporting.

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

We have audited Century Bancorp, Inc.’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control—
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Century Bancorp, Inc.’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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 
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. 

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. 

In our opinion, Century Bancorp, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria 
established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of 
Century Bancorp, Inc. as of December 31, 2016 and 2015 and 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, 2016, and our report dated March 15, 2017, expressed an unqualified 
opinion on those consolidated financial statements.

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, 2016. 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, 2016, 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 53.
