FROM OUR CHAIRMAN:

billion in assets
By building on the strength of our 
relationships with small and medium-sized 
businesses, retail customers, and 
local governments and institutions, 
we increased our total assets 7.2% 
to $1.8 billion in 2008. 

When I founded Century 
40 years ago in an office
trailer on Fellsway West in
Somerville, I never dreamed
that we would grow to be 
the largest family controlled
bank in New England, and in
2008, one of the very few
banks in the nation with 
a solid balance sheet and 
increasing earnings. 

Marshall M. Sloane

As we approach our anniversary celebration in May, there
are so many memories of loyal customers and Century 
Associates, deals done, and most of all, people helped and
communities that prospered. It seems like not that long
ago that I cut the first ribbon on opening day, May 1,
1969, and I’ve been blessed to cut many more new office
ribbons in the years that followed. I note with sadness 
the passing in 2008 of our Founding Director, Henry L. 
Foster, DVM. I am grateful for his 39 years of devoted 
service and wisdom.

My father landed in Boston from Russia 100 years ago 
next March. He had a strong conviction that success in
America was only limited by one's work ethic and values.
He instilled in me a strict moral compass and the values of
honesty, integrity and good character. He would be proud,
but not too surprised, by what Century has become.

I give much of the credit for our success to what we 
call our “family values”: hard work, unwavering focus, 
patient expectations, ethical behavior, and a lifelong 

commitment to our home communities. I am proud that
my three children, and the entire Century family, will carry
on these values as they build Century for the future.

I’ve been a banker for over 50 years. I thought I’d seen 
it all, but many of the events of the past couple of months
have left me astounded: monumental write-offs, absurd 
executive compensation, bank failures, huge forced 
mergers, frauds, depositor panics, and now the deepest 
recession since the Great Depression. Over the years, I have
lost plenty of sleep worrying about events like these to 
ensure Century would survive and prosper. In the 90’s, 
I told my family that sound management principles are 
as important during a recession as when times are 
prosperous. I am proud to say we are sound, profitable,
and growing.

Century has always been a culture based on risk 
management. We are spending more time than ever on
loan portfolio quality and underwriting standards. I feel
confident that by maintaining our centralized control of
lending in local markets, we’ll be fine. 

Most of all, I have faith in the United States, the 
economy of Massachusetts, and the core Greater Boston
communities we serve. I’m proud of the skills and 
commitment of our management team, and take great
pride in our 40 years of achievement. I’m already making
plans for our next 40 years.  

Sincerely,

Marshall M. Sloane
Founder & Chairman

DEAR FELLOW SHAREHOLDERS:

2008 was a strong and positive year for Century 
Bancorp. Our earnings, assets, capital, and branch 
footprint all grew meaningfully. Despite the most 
challenging business environment in a generation, 
each of our business units exceeded their goals. 

Here are some highlights:

Net income for the year ended December 31, 2008
increased 15% to $9,046,000, or $1.63 per diluted
share, compared to $7,864,000, or $1.42 per 
diluted share for 2007.

Total assets increased 7.2% from $1.7 billion 
at December 31, 2007 to $1.8 billion at 
December 31, 2008.

Net interest income increased 14.2% due to an 
improvement of 35 basis points in the net interest
margin to 3.00%.

Total stockholders’ equity increased from 
$118.8 million at year-end 2007 to $120.5 million 
at year-end 2008. Book value per share increased 
to $21.76.

Total loans increased by 15.1% from year-end 2007
to $836 million at year-end 2008, including a 20.5%
increase in commercial and industrial loans. 

Jonathan G. Sloane and Barry R. Sloane

Total deposits grew $135 million from year-end 
2007 to 2008, or 12%.

The efficiency ratio, a key measure of operating 
effectiveness, improved (declined) from 77.5% 
to 70.6% from 2007 to 2008.

We opened two new branches: Main Street in 
Winchester and Riverside Avenue in Medford; 
and repositioned our Medford Square branch to 
the very center of the Square. Each location has 
accomplished significant deposit growth, further 
increasing our market share and our commitment 
to the communities we serve.

Institutional Services increased its lockbox and 
related cash management fees by 9% and grew 
deposit balances by 22% in 2008.

15% increase in net income 

Despite the challenging economic
climate, we grew our net income by
staying true to our core values and
focused on our communities. 

491070.Text.QX7:Layout 1  2/20/09  3:57 PM  Page 2

22branch locations

Continually seeking ways to 
improve service and lower costs, 
we optimized and expanded our 
branch network to 22 offices in 17 
Massachusetts cities and towns. 

Century was founded 40 years ago on the philosophy of careful risk 
management and centralized in-market lending, long before these 
imperatives were cited as absent in the recent analysis of troubled banks.  

A year ago, we perceived a significant deterioration in national credit quality,
so we fortified our loan approval mechanism. The improved process requires
daily Executive review and approval on all bank lending.

Our nonperforming assets (“NPA”) increased from $1.8 million at year-end
2007 to $3.7 million at year-end 2008. The NPAs represent a small 
percentage of our loan portfolio, less than half of 1%, and the Bank has 
no foreclosed real estate owned. Regardless, we remain relentlessly devoted
to proactively managing the credit quality of our portfolio.

Independent thinking.

The troubles of the giant, multinational banks have further distracted 
their management’s attention from their communities and clients. Some
years ago, we wrote of our concern about “living in the land of the giants.”
The “giants” appear less formidable today. Clients and bankers have moved
to Century as a refuge from the “management by headline” that defines
those multinational banks. To seize this opportunity, we recognize how 
critical it is that we remain focused on strengthening our local ties. It is 
a relief to be fortunate to spend our days on constructive business building
initiatives, rather than on lobbying for federal assistance.

We did receive preliminary approval in December for $30 million of the 
Capital Purchase Program (“CPP”) preferred capital stock investment from 
the U.S. Treasury's Troubled Asset Relief Program (“TARP”). However, in 
early February 2009, we cancelled our scheduled closing. We simply felt 
that the relatively high percentage coupon, 10-year stock warrants, and 
the almost daily announcements of proposed restrictions on dividends 
and acquisitions did not justify the “insurance” value of the additional 
and, in our case, unneeded capital.

Looking ahead.

There is no doubt of the severity of this recession, 
but conservative economic forecasts foreshadow 
a leveling of GDP in late 2009, followed by modest
growth in 2010. We feel comfortable that we can 
manage our way through this economic contraction
without the TARP/CPP money and its burdens. There is
no doubt that we are living through a deleveraging of
American consumers and corporations. While less debt
will restrain spending and GDP growth in the short
term, less high-rate debt is a good and productive 
development for America. We acknowledge recessions
are painful for our communities and clients, but we are
certain they will emerge stronger at the conclusion of
this challenging period.

As we mark our 40th anniversary, we are confident 
that, with the continued support and commitment of
our 400 Associates, Century will continue to prosper 
in the years ahead. Thank you for your business, 
your share ownership, and your confidence in 
our leadership.

Sincerely,

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 is facing unprecedented challenges in the face 
of the current economic crisis. The global and U.S. economies are experiencing
significantly reduced business activity as a result of, among other factors, 
disruptions in the financial system during the past year. Dramatic declines in the
housing market, and increased foreclosure levels and unemployment rates, have
resulted in significant writedowns of asset values by financial institutions, 
including government-sponsored entities and major commercial and investment
banks. These writedowns, initially of mortgage-backed securities but spreading 
to credit default swaps and other derivative securities, have caused many financial 
institutions to seek additional capital; to merge with larger and stronger 
institutions; and, in some cases, to fail. The Company is fortunate that the 
markets it serves have been impacted to a lesser extent than many areas 
around the country. 

In response to the financial crises affecting the banking system and financial 
markets, there have been several recent announcements of federal programs
designed to purchase assets from, provide equity capital to, and guarantee 
the liquidity of the industry. 

On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (the
“EESA”) was signed into law. The EESA authorizes the U.S. Treasury to, among
other things, purchase up to $700 billion of mortgages, mortgage-backed 
securities, and certain other financial instruments from financial institutions for
the purpose of stabilizing and providing liquidity to the U.S. financial markets.
The Company does not expect to participate in the sale of any of its assets 
into these programs. EESA also immediately increased the FDIC deposit 
insurance limit from $100,000 to $250,000 through December 31, 2009. 

On October 14, 2008, the U.S. Treasury announced that it will purchase equity
stakes in a wide variety of banks and thrifts. Under this program, known as the
Troubled Asset Relief Program Capital Purchase Program (the “TARP Capital
Purchase Program”), the U.S. Treasury has made approximately $250 billion of 
capital available (from the $750 billion authorized by the EESA) to U.S. financial
institutions in the form of preferred stock. In conjunction with the purchase of 
preferred stock, the U.S. Treasury will receive warrants to purchase common stock
with an aggregate market price equal to 15% of the preferred investment.
Participating financial institutions will be required to adopt the U.S. Treasury’s 

3

standards for executive compensation, dividend restrictions and corporate 
governance for the period during which the U.S. Treasury holds equity issued under
the TARP Capital Purchase Program. The U.S. Treasury also announced that nine
large financial institutions had already agreed to participate in the TARP Capital
Purchase Program. Subsequently, a number of smaller institutions have participated
in the TARP Capital Purchase Program. On December 18, 2008, the Company
announced, in a press release, it had received preliminary approval from the U.S.
Treasury to participate in the TARP Capital Purchase Program, in an amount up to
$30 million in the form of Century Bancorp, Inc. preferred stock and warrants to
purchase Class A common stock. In light of uncertainty surrounding additional
restrictions that may be imposed on participants under pending legislation, the
Company, on January 14, 2009, informed the U.S. Treasury that it would not be
closing on the transaction on January 16, 2009, as originally scheduled. The
Company will monitor developments and may decide to close on the transaction
once uncertainties are resolved if it is in the best interest of the Company to do 
so, though the U.S. Treasury did not commit to close at a future date.

On October 14, 2008, the U.S. Treasury and the FDIC jointly announced a 
new program, known as the Temporary Liquidity Guarantee Program (“TLGP”), to
strengthen confidence and encourage liquidity in the nation’s banking system.
The TLGP consists of two programs: the Debt Guarantee Program (“DGP”) and
the Transaction Account Guarantee Program (“TAGP”). Under the DGP, the FDIC
will guarantee certain newly issued senior unsecured debt of participating banks,
thrifts and certain holding companies issued from October 14, 2008 through
June 30, 2009, which debt matures on or prior to June 30, 2012, up to a fixed
maximum amount per participant. In addition, under the TAGP, the FDIC will fully
guarantee deposits in noninterest bearing transaction accounts without dollar 
limitation through December 31, 2009. Institutions opting to participate in the
DGP will be charged a 50-, 75- or 100-basis point fee (depending on maturity)
for the guarantee of eligible debt, and a 10-basis point assessment will be 
applicable to deposits in noninterest bearing transaction accounts at institutions
participating in the TAGP that exceed the existing deposit insurance limit of
$250,000. The Company opted to participate in both the DGP and the TAGP.

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,
2008, the Company had total assets of $1.8 billion. Currently, the Company 
operates 22 banking offices in 17 cities and towns in Massachusetts ranging from
Braintree in the south to Beverly 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.

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 the interest paid on deposits and borrowings. The results of operations are
also affected by the level of income/fees from loans and 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, nonprofit organizations and individuals. 
It emphasizes service to small and medium-sized businesses and retail customers 
in its market area. 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 to its corporate and institutional 
customers automated lockbox 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 Linsco/Private Ledger Corp., a full-service securities brokerage business.

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.   

The Company is also a provider of financial services, including cash management,
transaction processing and short-term financing, to municipalities in Massachusetts
and Rhode Island. The Company has deposit relationships with approximately 43%
of the 351 cities and towns in Massachusetts.

The Company had net income of $9,046,000 for the year ended December 31,
2008, compared with net income of $7,864,000 for the year ended December 31,
2007 and net income of $4,688,000 for the year ended December 31, 2006.
Diluted earnings per share were $1.63 in 2008, compared to $1.42 in 2007 and
$0.84 in 2006. Included in income for 2007 is a $1,321,000 pre-tax gain on the
sale of the building that houses the Company’s Medford Square branch. Included in
income for 2006 is a pre-tax gain of $600,000 from the sale of the Company’s
rights to future royalty payments for a portion of its Merchant Credit Card 
customer base.

Throughout 2007 and 2008, the Company has seen improvement in its net 
interest margin as illustrated in the graph below:

The primary factors accounting for the increase in net interest margin are: 

• a continuing decline in the cost of funds as a result of increased pricing 

discipline related to deposits,

• an increase in average loans outstanding during 2008,

• the maturity of lower-yielding investment securities,

• an increase in the slope of the yield curve,

During 2008, the U.S. economy has experienced a lower rate environment along
with a steepening of the yield curve, which means that the spread between the
long-term and short-term yields has increased. This has positively impacted 
the net interest margin. During 2007, rates fell and the yield curve steepened
somewhat. This positively impacted the net interest margin. During 2006, the
Company’s earnings were negatively impacted primarily by a decrease in net 
interest income. This decrease was primarily due to the inverted yield curve 
during 2006 as well as increased funding costs.

Total assets were $1,801,566,000 at December 31, 2008, an increase of 7.2%
from total assets of $1,680,281,000 on December 31, 2007.

On December 31, 2008, stockholders’ equity totaled $120,503,000, compared
with $118,806,000 on December 31, 2007.  Book value per share increased to
$21.76 at December 31, 2008 from $21.43 on December 31, 2007.

On August 17, 2007, the Company sold the building that houses one of its branches
located at 55 High Street, Medford, Massachusetts, for $1.5 million at market
terms. The Bank relocated this branch to 1 Salem Street (formerly 3 Salem Street),
Medford, Massachusetts. This sale resulted in a pre-tax gain of $1,321,000. The
branch opened on May 5, 2008. 

On April 14, 2008, the Company opened a branch located on Riverside Avenue in
Medford, Massachusetts. On November 17, 2008, the Company opened a branch
located on Main Street in Winchester, Massachusetts. During October 2008, the
Company received regulatory approval to close a branch on Albany Street in
Boston, Massachusetts. This branch closed during the first quarter of 2009. 

During the fourth quarter of 2007, the Company sold the assets associated with
the Sherman Union branch located on Commonwealth Avenue in Boston,
Massachusetts, as well as automated teller machines (“ATMs”) located at or near
Boston University. The buyer assumed the leases for the branch and ATMs. The
deposits associated with the Sherman Union branch were transferred to Century’s
Hotel Commonwealth branch located at 512 Commonwealth Avenue in Boston,
Massachusetts. This resulted in a gain of $115,000.

• an increase in the loan yield due to an increase in prepayment fees, particularly

in the second quarter of 2007, and

• an increase in investment yields due, in part, to taking advantage of elevated
yields in the municipal auction rate securities market, particularly in the third
quarter of 2008.

On February 7, 2006, the Company announced that it had renewed its contract
with NOVA Information Systems, a wholly owned subsidiary of U.S. Bancorp, and
had also sold its rights to future royalty payments for a portion of its Merchant
Credit Card customer base for $600,000, which the Bank has included as 
other income.

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 prepayments of loans and changes in market interest rates, will 
continue to positively impact the net interest margin.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Impaired Investment Securities
If a decline in fair value below the amortized cost basis of an investment security 
is judged to be “other-than-temporary,” the cost basis of the investment is written
down to fair value. The amount of the writedown is included as a charge to 
earnings. An other-than-temporary impairment exists for debt securities if it is
probable that the Company will be unable to collect all amounts due according 
to contractual terms of the security. Some factors considered for other-than-
temporary impairment related to a debt security include an analysis of yield which
results in a decrease in expected cash flows, whether an unrealized loss is issuer
specific, whether the issuer has defaulted on scheduled interest and principal 
payments, whether the issuer’s current financial condition hinders its ability to 
make future scheduled interest and principal payments on a timely basis or
whether there was a downgrade in ratings by rating agencies.

The Company has the ability and intent to hold all securities with an unrealized
loss until recovery of fair value, which may be maturity.

FINANCIAL CONDITION 
Investment Securities
The Company’s securities portfolio consists of securities available-for-sale and
securities held-to-maturity.

Securities available-for-sale consist of certain U.S. Treasury and U.S. Government
Sponsored Enterprise mortgage-backed securities; state, county and municipal 
securities; foreign 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, 2008 totaled $495,585,000 and includes gross unrealized 
gains of $4,783,000 and gross unrealized losses of $5,244,000. A year 
earlier, securities available-for-sale were $388,104,000 including gross 
unrealized gains of $1,728,000 and unrealized losses of $2,077,000. In 2008,
the Company recognized gross gains of $251,000 and gross losses of $2,000
on the sale of available-for-sale securities. The Company also recognized
$76,000 in realized losses on the writedown of two stocks. In 2007, the
Company recognized gross gains of $153,000 on the sale of one stock.

Securities which management intends to hold until maturity consist of
U.S. Government Sponsored Enterprises and mortgage-backed securities.
Securities held-to-maturity as of December 31, 2008 are carried at their 
amortized cost of $184,047,000 and exclude gross unrealized gains of
$1,820,000 and gross unrealized losses of $434,000. A year earlier, securities
held-to-maturity totaled $183,710,000 excluding gross unrealized gains of
$131,000 and gross unrealized losses of $2,137,000.

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 formula allowance and specific
allowances for identified problem loans.

The formula allowance evaluates groups of loans to determine the allocation 
appropriate within each portfolio segment. Individual loans within the commercial
and industrial, commercial real estate and real estate construction loan portfolio
segments are assigned internal risk ratings to group them with other loans 
possessing similar risk characteristics. Changes in risk grades affect the amount of
the formula allowance. Risk grades are determined by reviewing current collateral
value, financial information, cash flow, payment history and other relevant facts 
surrounding the particular credit. Provisions for losses on the remaining commercial
and commercial real estate loans are based on pools of similar loans using a 
combination of historical net loss experience and qualitative adjustments. For the 
residential real estate and consumer loan portfolios, the reserves are calculated by
applying historical charge-off and recovery experience and qualitative adjustments
to the current outstanding balance in each loan category. Loss factors are based
on the Company’s historical net loss experience, as well as regulatory guidelines.

Specific allowances for loan losses entail the assignment of allowance amounts 
to individual loans on the basis of loan impairment. Certain loans are evaluated
individually and are judged to be impaired when management believes it is 
probable that the Company will not collect all the contractual interest and 
principle payments as scheduled in the loan agreement. 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.

The formula allowance and specific allowances also include management’s 
evaluation of various conditions, including business and economic conditions,
delinquency trends, charge-off experience and other quality factors.

Management has identified certain risk factors, which could impact the degree of
loss sustained within the portfolio. These include: (a) market risk factors, such as
the effects of economic variability on the entire portfolio, and (b) 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 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 industry concentrations and geographic
concentrations or trends that may exacerbate losses resulting from economic
events which the Company may not be able to fully diversify out of its portfolio.

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.

Included in Obligations Issued by States and Political Subdivisions as of December 31, 2008, are $33,300,000 of auction rate municipal obligations (“ARSs”) and
$20,000,000 of variable rate demand notes (“VRDNs”) with unrealized losses of $1,254,000 for ARSs. VRDNs’ market value equals the carrying value. These debt 
securities were issued by governmental entities, but are not necessarily debt obligations of the issuing entity. Of the total of $53,300,000 of ARSs and VRDNs,
$25,000,000 are obligations of governmental entities and the remainder are obligations of large nonprofit entities. These obligations are variable rate securities with 
long-term maturities whose interest rates are set periodically through an auction process for ARSs and by prevailing market rates for VRDNs. Should the auction not 
attract sufficient bidders, the interest rate adjusts to the default rate defined in each obligation’s underlying documents. The Company increased its holdings in these 
types of securities during the second and third quarters of 2008 to take advantage of yields available due to market disruption. Although many of these issuers have 
bond insurance, the Company purchased the securities based on the creditworthiness of the underlying obligor.  

In the case of a failed auction, the Company may not have access to funds as only a limited market exists for failed ARSs. As of December 31, 2008, three of the Company’s
ARSs were purchased subsequent to their failure with a fair value of $12,000,000 and an amortized cost of $13,300,000. Three securities issued by governmental entities
were purchased prior to their failure with a fair value and amortized cost of $10,000,000. The remaining securities were issued by governmental entities, and large 
nonprofit entities, and are the debt of nonprofit organizations which the Company believes to be creditworthy. As of December 31, 2008, the weighted average taxable
equivalent yield on these securities was 5.69%.

The majority of the Company’s securities AFS are classified as Level 2, as defined in footnote 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. Market indicators and
industry and economic events are also monitored. The decline in fair value of $460,000 from amortized cost for available-for-sale securities is attributable to changes in
interest rates and not credit quality. 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, 2008.

Securities available-for-sale totaling $3,470,000, or 0.19% of assets, are classified as Level 3, as defined in footnote 1 of the “Notes to Consolidated Financial Statements.”
These securities are generally equity investments or municipal securities with no readily determinable fair value. 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 primarily refer to debt securities of Fannie Mae and Freddie Mac. Control of these enterprises was directly taken over
by the U.S. Government in the third quarter of 2008.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

At December 31, 2008 and 2007, the Bank had no investments in obligations of individual states, counties, municipalities or nongovernment corporate entities 
which exceeded 10% of stockholders’ equity. Additionally, in 2008, there were sales totaling $123,704,000 in gross proceeds in state, county or municipal securities 
resulting in gross gains of $46,000 and gross losses of $0. There were no sales of state, county or municipal securities in 2007. In 2008, sales of securities totaling
$238,894,000 in gross proceeds resulted in a net realized gain of $249,000. One equity security was sold during 2007 with gross proceeds of $336,000 resulting 
in a gain of $153,000. The book value of two equity securities was written down $76,000 during 2008. 

Debt securities of Government Sponsored Enterprises primarily refer to debt securities of Fannie Mae and Freddie Mac. Control of these enterprises was directly taken
over by the U.S. Government in the third quarter of 2008.

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. The Company grants single and multi-family residential loans, commercial and commercial
real estate 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 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 following summary shows the composition of the loan portfolio at the dates indicated.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

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 catgory.
There is little concentration to any one business sector, and loan risks are generally diversified among many borrowers.

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 Eastern Massachusetts and Southern New Hampshire. Loans are normally extended in amounts up to a maximum of 80% of appraised value and
normally for terms between three to five years. Amortization schedules are long term and thus a balloon payment is 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.

Residential real estate (1-4 family) includes two categories of loans. Included in residential real estate are approximately $8,498,000 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 but normally only one- or three-year adjustable interest rates are used. 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, 2008, the Company was obligated to advance a total of $16,642,000 to complete projects under construction.

At December 31, 2008 and December 31, 2007, impaired loans had specific reserves of $600,000 and $75,000, respectively. There were no impaired loans with 
specific reserves from December 31, 2004 through December 31, 2006.

The Company was servicing mortgage loans sold to others without recourse of approximately $768,000, $559,000, $798,000, $1,078,000 and $1,538,000 
at December 31, 2008, 2007, 2006, 2005 and 2004, respectively. Additionally, the Company services mortgage loans sold to others with limited recourse. The 
outstanding balance of these loans with limited recourse was approximately $56,000, $65,000, $72,000, $80,000 and $86,000 at December 31, 2008, 2007,
2006, 2005 and 2004, respectively.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

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, are reviewed 
on a regular basis by senior management and monthly by the Board of Directors of the Bank.

Nonaccrual loans increased from 2007 to 2008 primarily as a result of eight consumer mortgages totaling $1,649,000. Nonaccrual loans increased from 2006 
to 2007 primarily as a result of three consumer mortgages totaling $938,000. The relatively low level of nonperforming assets of $135,000 in 2006 and $949,000
in 2005 resulted from fewer additions to nonperforming assets during the year combined with an improvement in the resolution of nonperforming assets including
payments on nonperforming loans.

In addition to the above, the Company continues to monitor closely $21,807,000 and $14,117,000 at December 31, 2008 and 2007, 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, 2008, although such values may fluctuate with changes in the economy and the real estate market.

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, the 
financial 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 loan losses for the years indicated.

These provisions are the result of management’s evaluation of the 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 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 increased during 2007 and 2008 due to an increase 
in commercial loan charge-offs as a result of the weakening of the overall economy.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

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 
economic conditions. Although the allowance is allocated between categories, the entire allowance is available to absorb losses attributable to all loan categories. 
At December 31 of each year listed below, the allowance was comprised of the following:

The shift in the allocations of the allowance for loan losses in 2007 is the result of the implementation of guidance issued by the FDIC. The current allocation is based on
historical charge-off rates with additional allocations based on risk factors for each category and general economic factors. Prior to 2007, the allowance related to general
economic factors was included solely in the unallocated category.

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

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

Borrowings
The Bank’s borrowings consisted primarily of FHLB borrowings collateralized by a blanket pledge agreement on the Bank’s FHLB stock, certain qualified investment securities,
deposits at the FHLB and residential mortgages held in the Bank’s portfolios. The Bank’s borrowings from the FHLB totaled $237,000,000, a decrease of $52,250,000 
from the prior year. The Bank’s remaining term borrowing capacity at the FHLB at December 31, 2008 was approximately $194,415,000. In addition, the Bank has a
$14,500,000 line of credit with the FHLB. See Note 12, “Other Borrowed Funds and Subordinated Debentures,” for a schedule, their interest rates and other information.

Subordinated Debentures
In May 1998, the Company consummated the sale of a Trust Preferred Securities offering, in which it issued $29,639,000 of subordinated debt securities due 2029 to 
its newly formed unconsolidated subsidiary, Century Bancorp Capital Trust.

Century Bancorp Capital Trust then issued 2,875,000 shares of Cumulative Trust Preferred Securities with a liquidation value of $10 per share. These securities pay 
dividends at an annualized rate of 8.30%. The Company redeemed through its subsidiary, Century Bancorp Capital Trust, its 8.30% Trust Preferred Securities, 
January 10, 2005.

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

Century Bancorp Capital Trust II then issued 35,000 shares of Cumulative Trust Preferred Securities with a liquidation value of $1,000 per share. These securities pay 
dividends at an annualized rate of 6.65% for the first ten years and then convert 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 
$112,510,000, an increase of $26,520,000 from the prior year. See Note 11, “Securities Sold Under Agreements to Repurchase,” for a schedule, including their 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 18.9% in 2008 to $46,750,000, compared with $39,313,000 in 2007. The increase in net interest income for 2008 was mainly due to a 13.2% or a 35 basis
point increase in the net interest margin. The level of interest rates, the ability of the Company’s earning assets and liabilities to adjust to changes in interest rates and the
mix of the Company’s earning assets and liabilities affect net interest income. The net interest margin on a fully taxable equivalent basis increased to 3.00% in 2008 from
2.65% in 2007, and from 2.40% in 2006.

Additional information about the increased 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.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

The following table summarizes the year-to-year changes in the Company’s net interest income resulting from fluctuations in interest rates and volume changes in 
earning assets and interest-bearing liabilities. Changes due to rate are computed by multiplying the change in rate by the prior year’s volume. Changes due to volume
are computed by multiplying the change in volume by the prior year’s rate. Changes in volume and rate that cannot be separately identified have been allocated in 
proportion to the relationship of the absolute dollar amounts of each change.

Average earning assets were $1,556,527,000 in 2008, an increase of $77,178,000 or 5.2% from the average in 2007, which was 3.6% lower than the average in 2006.
Total average securities, including securities available-for-sale and securities held-to-maturity, were $666,928,000, an increase of 7.3% from the average in 2007. The
increase in securities volume was mainly attributable to an increase in tax-exempt securities. Investments in tax-exempt securities increased to take advantage of increased
yields in this market. An increase in securities balances resulted in higher securities income, which increased 25.9% to $29,652,000 on a fully tax equivalent basis. Total
average loans increased 6.8% to $775,337,000 after increasing $2,078,000 in 2007. The primary reason for the increase in loans was due in large part to an increase in
residential first and second mortgage lending as well as an increase in commercial real estate lending. The increase in loan volume partially offset by decreases in loan rates
resulted in lower loan income, which decreased by 5.1% or $2,703,000 to $50,199,000. Total loan income was $51,466,000 in 2006.

The Company’s sources of funds include deposits and borrowed funds. On average, deposits showed an increase of 1.1% or $13,193,000 in 2008 after decreasing 
by 4.3% or $53,898,000 in 2007. Deposits increased in 2008 primarily as a result of increases in savings and money market accounts, which increased by 21.8% or
$84,759,000, somewhat offset by decreases in time deposits, which decreased by 18.5% or $62,047,000. During 2007, deposits decreased primarily as a result of
decreases in money market accounts, which decreased by 15.2% or $49,721,000 and time deposits, which decreased by 6.4% or $23,073,000. Borrowed funds and 
subordinated debentures increased by 33.9% in 2008 following a decrease of 12.3% in 2007. The majority of the Company’s borrowed funds are borrowings from the
FHLB and retail repurchase agreements. Borrowings from the FHLB increased by approximately $57,208,000, and retail repurchase agreements increased by $4,711,000.
Interest expense totaled $35,914,000 in 2008, a decrease of $7,891,000 or 18.0% from 2007 when interest expense decreased 0.3% from 2006. The decrease in 
interest expense is primarily due to market decreases in deposit rates and continued deposit pricing discipline.

Provision for Loan Losses
The provision for loan losses was $4,425,000 in 2008, compared with $1,500,000 in 2007 and $825,000 in 2006. These provisions are the result of 
management’s evaluation of the amounts and 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 increased during 2008 primarily as a result of growth in the loan portfolio, nonperforming
loans and an increase in net charge-offs during the year as well as management’s quantitative analysis of the loan portfolio.

The allowance for loan losses was $11,119,000 at December 31, 2008, compared with $9,633,000 at December 31, 2007. Expressed as a percentage of outstanding
loans at year-end, the allowance was 1.33% in 2008 and 2007. This ratio remained stable as a result of management’s evaluation of the loan portfolio.

Nonperforming loans, which include all nonaccruing loans, totaled $3,661,000 on December 31, 2008, compared with $1,312,000 on December 31, 2007.
Nonperforming loans increased primarily as a result of an increase in both nonperforming consumer mortgages and commercial loans.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

Other Operating Income 
During 2008, the Company continued to experience positive 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 offered through Linsco/Private Ledger Corp. (“LPL”), an
unaffiliated registered securities broker-dealer and investment advisor. 

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, a full-service
securities brokerage business. Registered representatives employed by LPL offer
limited investment advice, execute transactions and assist customers in financial
and retirement planning. LPL provides research to and supervises its 
representatives. The Bank receives a share in the commission revenues.

Total other operating income in 2008 was $13,975,000, an increase of
$27,000 or 0.2% compared to 2007. This increase followed an increase of
$2,583,000 or 22.7% in 2007, compared to 2006. Included in 2007 is the
$1,321,000 pre-tax gain on the sale of the building that houses the Company’s
Medford Square branch. Service charge income, which continues to be a major
area of other operating income totaling $8,190,000 in 2008, increased
$611,000 compared to 2007. This followed an increase of $877,000 compared
to 2006. Service charges on deposit accounts increased mainly because of
increases in fees. Lockbox revenues totaled $2,953,000, down $3,000 in 2008
following an increase of $184,000 in 2007. Other income totaled $2,479,000,
up $792,000 in 2007 following a decrease of $55,000 in 2007. The increase in
2008 was mainly attributable to an increase of $420,000 in the growth of cash
surrender values on life insurance policies which was attributable to higher
returns on life insurance policies, an increase of $143,000 in foreign ATM 
surcharges and an increase of $138,000 in royalty payments on the merchant
and credit card customer base. The decrease in 2007 was mainly attributable to
an increase of $217,000 in foreign ATM surcharges and an increase of $183,000
in the growth of cash surrender values on life insurance policies that was 
attributable to higher returns on life insurance policies offset by a pre-tax gain 
of $600,000 from the sale of rights to future royalty payments for a portion of
the Company’s Merchant Credit Card customer base during 2006. Foreign ATM
surcharges increased because of an increase in rates charged and the addition 
of ATMs. 

Operating Expenses 
Total operating expenses were $43,028,000 in 2008, compared to
$40,255,000 in 2007 and $40,196,000 in 2006.

Salaries and employee benefits expenses increased by $1,072,000 or 4.4% in
2008, after increasing by 3.1% in 2007. The increase in 2008 and 2007 was
mainly attributable to an increase in staff levels, merit increases in salaries and
increases in health insurance costs. Pension expense for 2009 is expected to
increase. 

Occupancy expense increased by $394,000 or 10.2% in 2008, following a
decrease of $55,000 or 1.4% in 2007. The increase in 2008 was primarily
attributable to an increase in rent expense associated with general rent 
escalations as well as retail branch expansion, depreciation and real estate taxes.
The decrease in 2007 was primarily attributable to an increase in rental income.

15

Equipment expense decreased by $83,000 or 2.8% in 2008, following a
decrease of $86,000 or 2.8% in 2007. The decrease in 2008 and 2007 was
primarily attributable to a decrease in depreciation expense. Other operating
expenses increased by $1,390,000 in 2008, which followed a $528,000
decrease in 2007. The increase in 2008 was primarily attributable to an increase
in FDIC assessments, legal expense, consulting expense and contributions to
charitable organizations. The decrease in 2007 was primarily attributable to 
a decrease in bank processing charges and legal expense. 

Currently, the Company pays approximately 5.3 basis points for FDIC deposit
insurance. Under a proposal by the FDIC, the assessment rate schedule would be
raised uniformly by 7 basis points (annualized) beginning on January 1, 2009.
Beginning with the second quarter of 2009, changes would be made to the
deposit insurance assessment system to make the increase in assessments fairer
by requiring riskier institutions to pay a larger share. As discussed in the “Recent
Market Developments” section, the Company has elected to participate in 
the TAGP. The annual impact to the Company of raising the deposit insurance
rate by seven basis points and participating in the TAGP will be approximately
$1.2 million in FDIC insurance premiums.

Provision for Income Taxes 
Income tax expense was $2,255,000 in 2008, $3,532,000 in 2007 and
$2,419,000 in 2006. The effective tax rate was 20.0% in 2008, 31.0% in 2007
and 34.0% in 2006. The decrease in the effective tax rate for 2008 and 2007
was mainly attributable to an increase in tax-exempt interest income as 
a percentage of taxable income. The federal tax rate was 34% in 2008, 2007 
and 2006.

On July 3, 2008, the Commonwealth of Massachusetts enacted a law that
included reducing the tax rates on net income applicable to financial institutions.
The rate drops from the current rate of 10.5% to 10% for tax years beginning
on or after January 1, 2010; to 9.5% for tax years beginning on or after January
1, 2011; and to 9% for tax years beginning on or after January 1, 2012 and 
thereafter. The Company has analyzed the impact of this law and as a result of
revaluing its net deferred tax assets, we calculated the impact to be additional
tax expense of approximately $80,000. This charge was recognized during the
third quarter of 2008. 

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.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

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)

+300
+200
+100
–100
–200
–300

(2.0) %
(1.8) % 
(1.2) % 
1.5  %
3.1  %
(5.9) %

(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 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
include cash and due from banks, federal funds sold and other temporary 
investments. Liquid assets totaled $199,982,000 on December 31, 2008, 
compared with $299,901,000 on December 31, 2007. In each of these two
years, deposit and borrowing activity has generally been adequate to support
asset activity.

Century Bancorp, Inc. AR ’08

The source of funds for dividends paid by the Company is dividends received from
the Bank. 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 $120,503,000 at December 31, 2008, compared
with $118,806,000 at December 31, 2007. The increase in 2008 was primarily
the result of earnings offset by an increase in accumulated other comprehensive
loss, net of taxes and dividends paid. The increase in accumulated other 
comprehensive loss was mainly attributable to an increase of $4,723,000 in the
pension liability, net of taxes, and an increase of $81,000 in the net unrealized
loss on the Company’s available-for-sale portfolio, net of taxes.

Federal banking regulators have issued risk-based capital guidelines, which 
assign risk factors to asset categories and off-balance-sheet items. The current
guidelines require a Tier 1 capital-to-risk assets ratio of at least 4.00% and a 
total capital-to-risk assets ratio of at least 8.00%. The Company and the Bank
exceeded these requirements with a Tier 1 capital-to-risk assets ratio of 15.30%
and 12.10%, respectively, and total capital-to-risk assets ratio of 16.38% and
13.19%, respectively, at December 31, 2008. Additionally, federal banking 
regulators have issued leverage ratio guidelines, which supplement the risk-based
capital guidelines. The minimum leverage ratio requirement applicable to the
Company is 4.00%; and at December 31, 2008, the Company and the Bank
exceeded this requirement with leverage ratios of 9.05% and 7.15%, respectively.

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 notational amounts of those instruments reflect the extent of involvement the Company has in these particular classes of financial instruments.

Management’s Discussion and Analysis of Results of Operations and Financial Condition

Century Bancorp, Inc. AR ’08

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-balance-sheet instruments. Financial instruments with off-balance-sheet risk
at December 31, are as follows:

Contract or Notational Amount

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 market value of standby letters of
credit was $117,000 and $109,000 for 2008 and 2007, respectively. 

Recent Accounting Developments 
Statement of Financial Accounting Standard No. 159 (“SFAS 159”), “The Fair 
Value Option for Financial Assets and Financial Liabilities.” In February 2007, the
Financial Accounting Standards Board (“FASB”) issued SFAS 159, which gives 
entities the option to measure eligible financial assets, and financial liabilities at fair
value on an instrument by instrument basis, that are otherwise not permitted to be
accounted for at fair value under other accounting standards. The election to use
the fair value option is available when an entity first recognizes a financial asset or
financial liability. Subsequent changes in fair value must be recorded in earnings.
This statement is effective as of the beginning of a company’s first fiscal year after
November 15, 2007. The Company adopted SFAS 159 on January 1, 2008 and did
not elect to apply the fair value to any existing financial instruments.

17

Statement of Financial Accounting Standards No. 141 (revised 2007), “Business
Combinations” (“SFAS 141R”) and Statement of Financial Accounting Standards 
No. 160, “Noncontrolling Interests in Consolidated Financial Statements, an
Amendment of ARB No. 51” (“SFAS 160”). In December 2007, the FASB issued
SFAS 141R and SFAS 160. These statements require significant changes in the
accounting and reporting for business acquisitions and the reporting of 
noncontrolling interests in subsidiaries. Among many changes under SFAS 141R, 
an acquirer will record 100% of all assets and liabilities at fair value for partial
acquisitions, contingent consideration will be recognized at fair value at the 
acquisition date with changes possibly recognized in earnings, and acquisition
related costs will be expensed rather than capitalized. SFAS 160 establishes new
accounting and reporting standards for the noncontrolling interest in a subsidiary.
Key changes under the standard are that noncontrolling interests in a subsidiary
will be reported as part of equity, losses allocated to a noncontrolling interest can
result in a deficit balance, and changes in ownership interests that do not result in
a change of control are accounted for as equity transactions and, upon a loss of
control, gain or loss is recognized and the remaining interest is remeasured at fair
value on the date control is lost. SFAS 141R applies prospectively to business 
combinations for which the acquisition is on or after the beginning of the first
annual reporting period beginning on or after December 15, 2008. The effective
date for applying SFAS 160 is also the first annual reporting period beginning on
or after December 15, 2008. Adoption of these statements will affect the
Company’s accounting for any business acquisitions occurring after the effective
date and the reporting of any noncontrolling interests in subsidiaries existing on 
or after the effective date. 

SFAS No. 162 (“SFAS 162”), “The Hierarchy of Generally Accepted Accounting
Principles.” In May 2008, the FASB issued SFAS No. 162, “The Hierarchy of
Generally Accepted Accounting Principles.” This statement identifies the sources 
of accounting principles and the framework for selecting the principles to be used 
in the preparation of financial statements of nongovernmental entities that are 
presented in conformity with generally accepted accounting principles (“GAAP”) 
in the United States (“the GAAP hierarchy”). This Statement shall be effective
60 days following the Security and Exchange Commission’s approval of the Public
Company Accounting Oversight Board (“PCAOB”) amendments to AU Section
411, “The Meaning of Present Fairly in Conformity with Generally Accepted
Accounting Principles.” The Company has not yet determined the impact of the
adoption of SFAS 162 to the Company’s statement of financial position or results 
of operations.

FASB Staff Position FAS 142-3 (“FSP FAS 142-3”), “Determination of the 
Useful Life of Intangible Assets.” In April 2008, the FASB issued FSP FAS 142-3,
“Determination of the Useful Life of Intangible Assets.” This FSP amends the 
factors that should be considered in developing renewal or extension assumptions
used to determine the useful life of a recognized intangible asset under FASB
Statement No. 142 (“SFAS 142”), “Goodwill and Other Intangible Assets.” 
The intent of this FSP is to improve the consistency between the useful life of a
recognized intangible asset under SFAS 142 and the period of expected cash flows
used to measure the fair value of the asset under FASB Statement No. 141 (revised
2007) (“SFAS 141R”), “Business Combinations,” and other U.S. generally accepted
accounting principles (“GAAP”). This Statement is effective for fiscal years 
beginning on or after December 15, 2008, and interim periods within those years.
Early application is not permitted. The Company has not yet determined the
impact of the adoption of FSP FAS 142-3 to the Company’s statement of financial
position or results of operations.

FSP EITF 03-6-01, “Determining Whether Instruments Granted in Share-Based
Payment Transactions Are Participating Securities.” In June 2008, the FASB issued
FSP EITF 03-6-1, “Determining Whether Instruments Granted in Share-Based
Payment Transactions Are Participating Securities.” This FSP addresses whether
instruments granted in share-based payment transactions are participating 
securities prior to vesting and, therefore, need to be included in the earnings 
allocation in computing earnings per share (“EPS”) under the two-class method
described in paragraphs 60 and 61 of FASB Statement No. 128 (“SFAS 128”),
“Earnings per Share.” The guidance in this FSP applies to the calculation of EPS
under SFAS 128 for share-based payment awards with rights to dividends or 
dividend equivalents. Unvested share-based payment awards that contain 
nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid)
are participating securities and shall be included in the computation of EPS 
pursuant to the two-class method. This Statement is effective for fiscal years 
beginning on or after December 15, 2008, and interim periods within those years.
All prior-period EPS data presented shall be adjusted retrospectively (including 
interim financial statements, summaries of earnings and selected financial data) 
to conform with the provisions of this FSP. Early application is not permitted. The
Company has determined that the impact of the adoption of FSP EITF 03-6-1 to
the Company’s statement of financial position or results of operations is immaterial.

FSP FAS 132(R)-1, “Employers’ Disclosures about Postretirement Benefit Plan
Assets.” In December 2008, the FASB issued FSP FAS 132(R)-1, “Employers’
Disclosures about Postretirement Benefit Plan Assets.” The FSP requires disclosure
of additional information about investment allocation, fair values of major asset 
categories of assets, the development of fair value measurements, and 
concentrations of risk. The FSP is effective for fiscal years ending after December
15, 2009; however, earlier application is permitted. The Company will adopt the 
FSP upon its effective date and will report the required disclosures in our Form 
10-K for the period ending December 31, 2009.

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’08

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. 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 inter-
est 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 independent appraisals and review of other factors
associated with the loans. 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 
In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS
157, “Fair Value Measurements,” which, among other things, requires enhanced 
disclosures about assets and liabilities carried at fair value. SFAS 157 is effective for
fiscal years beginning after November 15, 2007. FASB Staff Position 157-2 delays the
effective date of SFAS 157 for nonfinancial assets and nonfinancial liabilities, except
for items that are recognized or disclosed at fair value in the financial statements on a
recurring basis (at least annually) to fiscal years beginning after November 15, 2008.

23

SFAS 157 establishes a hierarchal disclosure framework associated with the level of
pricing observability utilized in measuring financial instruments at fair value. The three
broad levels defined by the SFAS 157 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 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 which are generally
included in this category are corporate bonds and loans, mortgage whole loans,
municipal bonds and OTC derivatives.

Level III – Instruments that 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, noninvestment
grade residual interests in securitizations, as well as certain highly structured OTC
derivative contracts.

In October 2008, the FASB issued FSP No. FAS 157-3, “Determining the Fair Value
of a Financial Asset When the Market for That Asset Is Not Active.” FSP No. FAS
157-3 clarifies the application of SFAS No. 157 in an inactive market, without 
changing its existing principles. The FSP was effective immediately upon issuance. 
The adoption of FSP No. FAS 157-3 did not have an effect on our financial 
condition, results of operations or cash flows.

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, 2008, short-term investments include highly liquid certificates
of deposit with original maturities of greater 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. If a decline in fair value below the
amortized cost basis of an investment is judged to be other-than-temporary, 
the cost basis of the investment is written down to fair value. The amount of the
writedown is included as a charge to earnings. Gains and losses on the sale 
of investment securities are recognized on the trade date on a specific 
identification basis.

491070.Financial.QX7.qxd:CA14518_Financials  2/20/09  6:54 PM  Page 24

The Company owns Federal Home Loan Bank (“FHLB”) stock which is 
considered a restricted equity security. As a voluntary member of the FHLB, the
Company is required to invest in stock of the FHLB in an amount equal to 4.5%
of its outstanding advances from the FHLB. Stock is purchased at par value. As
and when such stock is redeemed, the Company would receive from the FHLB 
an amount equal to the par value of the stock. At its discretion, the FHLB may
declare dividends on the stock. During the fourth quarter, the Company received
notice that the FHLB has placed a moratorium on all excess stock repurchases
and has placed limitations on quarterly dividend payouts.

LOANS 
Interest on loans is recognized based on the daily principal amount outstanding.
Accrual of interest is discontinued when loans become 90 days’ delinquent
unless the collateral is sufficient to cover both principal and interest and the
loan is in the process of collection. 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 which 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 income. 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 accounts for impaired loans at lower of cost or fair value, by either 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. 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.
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 rate of interest.

ACQUIRED LOANS
In accordance with 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. SOP No. 03-3 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 SOP No. 03-3. For such loans,

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’08

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, 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 also 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.

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,
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 which ultimately prove uncollectible. In determining the level of the
allowance, periodic evaluations are made of the loan portfolio which take into
account such factors as the character of the loans, loan status, financial posture
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 formula allowance, specific allowances, 
if appropriate, for identified problem loans and the unallocated allowance.

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.

BANK PREMISES AND EQUIPMENT 
Bank premises and equipment are stated at cost less accumulated depreciation
and amortization. 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

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’08

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. 

The goodwill impairment analysis is a two-step test. The first step, 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.

STOCK OPTION ACCOUNTING 
The Company follows the fair value recognition provisions of SFAS 123R for all
share-based payments, using the modified-prospective transition method. The
Company’s method of valuation for share-based awards granted utilizes the Black-
Scholes option-pricing model which was also previously used for the Company’s
pro forma information required under SFAS 123. 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 options to purchase an aggregate of 81,037 shares of
Class A common stock exercisable at December 31, 2008.

On December 30, 2005, the Board of Directors approved the acceleration and
immediate vesting of all unvested options with an exercise price of $31.60 or
greater per share. As a consequence, options to purchase 23,950 shares of Class A
common stock became exercisable immediately. The average of the high and low
price at which the Class A common stock traded on December 30, 2005, the date
of the acceleration and vesting, was $29.28 per share. In connection with this
acceleration, the Board of Directors approved a technical amendment to each of
the Option Plans to eliminate the possibility that the terms of any outstanding 
or future stock option would require a cash settlement on the occurrence of any
circumstance outside the control of the Company. Effective as of January 1, 2006,
the Company adopted SFAS 123R for all share-based payments. The Company
estimates that, as a result of this accelerated vesting, approximately $190,000 of
2006 noncash compensation expense was eliminated that would otherwise have
been recognized in the Company’s earnings.

The Company decided to accelerate the vesting of certain stock options 
primarily to reduce the noncash compensation expense that would otherwise 
be expected to be recorded in conjunction with the Company’s required 
adoption of SFAS 123R in 2006. There was no earnings impact for 2006 due 
to the Company’s adoption of SFAS 123R.

25

The Company uses the fair value method to account for stock options. All of 
the Company’s stock options are vested, and there were no options granted 
during 2008.

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.

In July 2006, the FASB issued Financial Accounting Standards Interpretation
No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 clarifies
the accounting for uncertainty in income taxes recognized in an enterprise’s
financial statements in accordance with FASB Statement No. 109, “Accounting
for Income Taxes.” FIN 48 prescribes a recognition threshold and measurement
attributable for the financial statement recognition and measurement of a tax
position taken or expected to be taken in a tax return. FIN 48 also provides
guidance on derecognition, classification, interest and penalties, accounting in
interim periods, disclosures and transitions. The Company adopted FIN 48 on
January 1, 2007. The adoption of FIN 48 did not have a material impact on 
the Company’s results of operations or its financial position.

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.

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, and participants are required to contribute to its cost. Individual life
insurance policies, which are owned by the Company, are purchased covering 
the lives of each participant.

Effective December 31, 2006, the Company adopted SFAS No. 158, “Employers’
Accounting for Defined Benefit Pension and Other Postretirement Plans — An
Amendment of FASB Statements No. 87, 88, 106, and 132(R),” which requires the
Company to recognize the overfunded or underfunded status of a single employer
defined benefit pension or postretirement plan as an asset or liability on its 

491070.Financial.QX7.qxd:CA14518_Financials  2/20/09  6:54 PM  Page 26

balance sheet and to recognize changes in the funded status in comprehensive
income in the year in which the change occurred. However, gains or losses, prior
service costs or credits, and transition assets or obligations that have not yet been
included in net periodic benefit cost as of the end of 2006, the fiscal year in which
the Statement is initially applied, are to be recognized as components of the 
ending balance of accumulated other comprehensive income, net of tax. The
Company recorded an additional $2,158,000 pension liability adjustment, net 
of tax, through stockholders’ equity, as a result of the adoption of SFAS 158.
SFAS 158 also required the Company to measure plan assets and benefit 
obligations as of December 31, 2008, the date of the Company’s fiscal year-end.

RECENT ACCOUNTING DEVELOPMENTS 
Statement of Financial Accounting Standard No. 159 ("SFAS 159"), “The Fair Value
Option for Financial Assets and Financial Liabilities.” In February 2007, the FASB
issued SFAS 159, which gives entities the option to measure eligible financial assets,
and financial liabilities at fair value on an instrument by instrument basis, that are 
otherwise not permitted to be accounted for at fair value under other accounting
standards. The election to use the fair value option is available when an entity first
recognizes a financial asset or financial liability. Subsequent changes in fair value
must be recorded in earnings. This statement is effective as of the beginning of a
company's first fiscal year after November 15, 2007. The Company adopted SFAS
159 on January 1, 2008 and did not elect to apply the fair value to any existing
financial instruments.

SFAS No. 141 (revised 2007), “Business Combinations” (“SFAS 141R”) and 
SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements,
an Amendment of ARB No. 51” (“SFAS 160”). In December 2007, the FASB
issued SFAS 141R and SFAS 160. These statements require significant changes in
the accounting and reporting for business acquisitions and the reporting of non-
controlling interests in subsidiaries. Among many changes under SFAS 141R, an
acquirer will record 100% of all assets and liabilities at fair value for partial
acquisitions, contingent consideration will be recognized at fair value at the
acquisition date with changes possibly recognized in earnings, and acquisition-
related costs will be expensed rather than capitalized. SFAS 160 establishes 
new accounting and reporting standards for the noncontrolling interest in a 
subsidiary. Key changes under the standard are that noncontrolling interests in a
subsidiary will be reported as part of equity, losses allocated to a noncontrolling
interest can result in a deficit balance, and changes in ownership interests that
do not result in a change of control are accounted for as equity transactions
and, upon a loss of control, gain or loss is recognized and the remaining interest
is remeasured at fair value on the date control is lost. SFAS 141R applies
prospectively to business combinations for which the acquisition is on or after
the beginning of the first annual reporting period beginning on or after
December 15, 2008. The effective date for applying SFAS 160 is also the first
annual reporting period beginning on or after December 15,  2008. Adoption 
of these statements will affect the Company’s accounting for any business 
acquisitions occurring after the effective date and the reporting of any 
noncontrolling interests in subsidiaries existing on or after the effective date. 

SFAS No. 162 (“SFAS 162”), “The Hierarchy of Generally Accepted Accounting
Principles.” In May 2008, the FASB issued SFAS No. 162, “The Hierarchy of
Generally Accepted Accounting Principles.” This statement identifies the sources
of accounting principles and the framework for selecting the principles to be
used in the preparation of financial statements of nongovernmental entities that
are presented in conformity with generally accepted accounting principles
(“GAAP”) in the United States (“the GAAP hierarchy”). This Statement shall be
effective 60 days following the Security and Exchange Commission’s approval of
the Public Company Accounting Oversight Board (“PCAOB”) amendments to 
AU Section 411, “The Meaning of Present Fairly in Conformity With Generally
Accepted Accounting Principles.” The Company has not yet determined the
impact of the adoption of SFAS 162 to the Company’s statement of financial
position or results of operations.

FASB Staff Position FAS 142-3 (“FSP FAS 142-3”), “Determination of the 
Useful Life of Intangible Assets.” In April 2008, the FASB issued FSP FAS 142-3,

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’08

“Determination of the Useful Life of Intangible Assets.” This FSP amends the 
factors that should be considered in developing renewal or extension 
assumptions used to determine the useful life of a recognized intangible asset
under FASB Statement No. 142 (“SFAS 142”), “Goodwill and Other Intangible
Assets.” The intent of this FSP is to improve the consistency between the useful
life of a recognized intangible asset under SFAS 142 and the period of expected
cash flows used to measure the fair value of the asset under FASB Statement
No. 141 (revised 2007) (“SFAS 141R”), “Business Combinations,” and other U.S.
generally accepted accounting principles (“GAAP”). This Statement is effective
for fiscal years beginning on or after December 15, 2008, and interim periods 
within those years. Early application is not permitted. The Company has not 
yet determined the impact of the adoption of FSP FAS 142-3 to the Company’s
statement of financial position or results of operations.

FSP EITF 03-6-01, “Determining Whether Instruments Granted in Share-Based
Payment Transactions Are Participating Securities.” In June 2008, the FASB
issued FSP EITF 03-6-1, “Determining Whether Instruments Granted in Share-
Based Payment Transactions Are Participating Securities.” This FSP addresses
whether instruments granted in share-based payment transactions are 
participating securities prior to vesting and, therefore, need to be included in
the earnings allocation in computing earnings per share (“EPS”) under the 
two-class method described in paragraphs 60 and 61 of FASB Statement
No. 128 (“SFAS 128”), “Earnings per Share.” The guidance in this FSP applies 
to the calculation of EPS under SFAS 128 for share-based payment awards with
rights to dividends or dividend equivalents. Unvested share-based payment
awards that contain nonforfeitable rights to dividends or dividend equivalents
(whether paid or unpaid) are participating securities and shall be included in 
the computation of EPS pursuant to the two-class method. This Statement is
effective for fiscal years beginning on or after December 15, 2008, and interim
periods within those years. All prior-period EPS data presented shall be adjusted
retrospectively (including interim financial statements, summaries of earnings and
selected financial data) to conform with the provisions of this FSP. Early applica-
tion is not permitted. The Company has determined that the impact 
of the adoption of FSP EITF 03-6-1 to the Company’s statement of financial
position or results of operations is immaterial.

FSP FAS 132(R)-1, “Employers’ Disclosures about Postretirement Benefit Plan
Assets.” In December 2008, the FASB issued FSP FAS 132(R)-1, “Employers’
Disclosures about Postretirement Benefit Plan Assets.” The FSP requires 
disclosure of additional information about investment allocation, fair values of
major asset categories of assets, the development of fair value measurements,
and concentrations of risk. The FSP is effective for fiscal years ending after
December 15, 2009; however, earlier application is permitted. The Company 
will adopt the FSP upon its effective date and will report the required disclosures
in our Form 10-K for the period ending December 31, 2009.

value pledged to secure public deposits and repurchase agreements amounting to $113,259,000 and $80,260,000 at December 31, 2008 and 2007, respectively.
Also included in securities available-for-sale at fair value are securities pledged for borrowing at the Federal Home Loan Bank amounting to $244,409,000 and
$233,544,000 at December 31, 2008 and 2007, respectively. The Company realized gross gains of $251,000 and gross losses of $2,000 from the proceeds of
$238,894,000 from the sales of available-for-sale securities for the year ended December 31, 2008. The Company realized gross gains of $153,000 in 2007 from
gross proceeds of $336,000 on the sale of one stock. The Company did not realize any gains or losses in 2006.

Debt securities of Government Sponsored Enterprises primarily refer to debt securities of Fannie Mae and Freddie Mac. Control of these enterprises was directly taken
over by the U.S. Government in the third quarter of 2008.

The weighted average remaining life of investment securities available-for-sale at December 31, 2008 and 2007 was 4.8 and 2.2 years, respectively. Excluding auction
rate municipal obligations (“ARSs”) and variable rate demand notes (“VRDNs”), which have maturities up to 30 years, but reprice more frequently, the estimated average
remaining life is 2.9 years for 2008. ARSs and VRDNs are included in Obligations of States and Political Subdivisions above. There were no holdings of ARSs and VRDNs
during 2007. Included in the weighted average remaining life calculation at December 31, 2008 and 2007 were $126,145,000 and $113,160,000, respectively, of
U.S. Government Sponsored Enterprise obligations that are callable at the discretion of the issuer. These call dates were not utilized in computing the weighted average
remaining life. 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.

The following table shows the temporarily impaired securities of the Company’s available-for-sale portfolio at  December 31, 2008. This table shows the 
unrealized 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.
There are 44 and 17 securities that are temporarily impaired for less than 12 months and for 12 months or longer, respectively, out of a total of 260 holdings at
December 31, 2008.

As of December 31, 2008, management has concluded that the unrealized losses below its investment securities are temporary in nature since they are not related 
to the underlying credit quality of the issuers, and the Company has the intent and ability to hold these investments for the time necessary to recover its cost which
for debt securities may be at maturity. 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 state and municipal securities and the nonagency mortgage-
backed securities were caused by changes in credit spreads and liquidity issues in the marketplace. 

In evaluating the underlying credit quality of a security, management considers several factors such as the credit notary of the obliger 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.

*The decline in fair value is attributable to change in 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, 2008. Excluded from the table above are two stocks that were written down by
$76,000. The current fair value is $96,000 with an unrealized loss of $13,000. These stocks were deemed to be impaired based on the extent of the decline in value and the length of time the stocks had
been trading below cost.

There are 5 and 63 securities that are temporarily impaired for less than 12 months and for 12 months or longer, respectively, out of a total of 174 holdings at

During 2007, the Company sold the building which houses one of its branches located at 55 High Street, Medford, Massachusetts, for $1,500,000 at market terms.
This property was sold to an entity affiliated with a director of the Company. The Bank financed $1,000,000 of this purchase at market terms. This sale resulted in 
a pre-tax gain of $1,321,000.

The Bank relocated this branch to 1 Salem Street (formerly 3 Salem Street), Medford, Massachusetts. This property is leased from an entity affiliated with Marshall 
M. Sloane, Chairman of the Board of the Company. The lease is for a period of 15 years. The annual base rent amount is $28,500 with annual increases based on the
consumer price index. The Company is also required to pay 25% of all real estate taxes and operating costs. The lease contains options to extend the lease for three
additional five-year periods. The lease was effective on September 1, 2007. The terms of the lease were based on an independent appraisal of the property and are
considered to be market terms. The branch opened on May 5, 2008.

The Company and its subsidiaries are obligated under a number of noncancelable operating leases for premises and equipment expiring in various years through 2026.
Total lease expense approximated $1,533,000, $1,349,000 and $1,113,000 for the years ended December 31, 2008, 2007 and 2006, respectively. Rental income
approximated $399,000, $351,000 and $69,000 in 2008, 2007 and 2006, respectively.

Future minimum rental commitments for noncancelable operating leases with initial or remaining terms of one year or more at December 31, 2008 were as follows:

Goodwill and Identifiable Intangible Assets
Historically, the Company has determined fair values of reporting units based on stock prices, market earnings and tangible book value multiples of peer companies 
for the reporting unit. During the third quarter of 2008, management determined that the Company’s goodwill should be tested for impairment as the Company’s
Class A common stock had been trading below book value per share. In the third quarter of 2008, management enhanced the valuation methodology with discounted
cash flow analysis. During the fourth quarter of 2008, management reviewed the assumptions used during the third quarter and concluded that the assumptions 
continued to be appropriate. Based on management’s assessment of the reporting unit’s fair value, goodwill is not considered to be impaired at December 31, 2008.

The changes in goodwill and identifiable intangible assets for the years ended December 31, 2008 and 2007 are shown in the table below.

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, in accordance with SFAS 114 (as amended). Specific provisions related to impaired loans recognized for
2008 for credit losses amounted to $2,519,000.

There were purchases of $13,367,000 and maturities of $9,897,000 for a net increase of $3,470,000 in the fair value of available-for-sale securities valued using 
significant unobservable inputs (Level 3), between January 1, 2008 and December 31, 2008. The increase was attributable to an increase in certain municipal securities
without readily available fair values. The securities in this category are generally equity investments or municipal securities with no readily determinable fair value. In the
judgment of management, the fair value of these securities was considered to approximate their carrying value because they were deemed to be fully collectible and the
rates paid on the securities were at least equal to rates paid on securities with similar maturities.

Subordinated debentures totaled $36,083,000 at December 31, 2008 and 2007. In May 1998, the Company consummated the sale of a trust preferred securities
offering, in which it issued $29,639,000 of subordinated debt securities due 2029 to its newly formed unconsolidated subsidiary Century Bancorp Capital Trust.

Century Bancorp Capital Trust then issued 2,875,000 shares of Cumulative Trust Preferred Securities with a liquidation value of $10 per share. These securities pay

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 pay
dividends at an annualized rate of 6.65% for the first ten years and then convert to the three-month LIBOR rate plus 1.87% for the remaining 20 years.

OTHER BORROWED FUNDS
There were no overnight federal funds purchased at December 31, 2008 and 2007. 

The Bank serves as a Treasury Tax and Loan depository under a note option with the Federal Reserve Bank of Boston. This open-ended interest-bearing borrowing carries an
interest rate equal to the daily federal funds rate less 0.25%. This amount totaled $1,413,000 and $489,000 at December 31, 2008 and 2007, respectively.

The Bank also has an outstanding loan in the amount of $145,000 and $146,000 at December 31, 2008 and 2007, respectively, borrowed against the cash value of a
whole life insurance policy for a key executive of the Bank.

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.

EARNINGS PER SHARE (“EPS”) 
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 2008, 2007 and 2006 was an increase of 1,719, 4,246 and
9,756 shares, respectively.

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 81,037 options exercisable at December 31, 2008.

Stock option activity under the plan is as follows:

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’08

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, 2008, that the Bank and the Company meet all capital adequacy requirements to which they are subject.

As of December 31, 2008, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective
action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier risk-based, and Tier 1 leverage ratios as set forth in the table below. 
There are no conditions or events since that notification that management believes would cause a change in the Bank’s categorization.

The Bank’s actual capital amounts and ratios are presented in the following table:

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, 2008. 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.

Employee Benefits

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 pension plans participating in SBERA. The Trustees of
SBERA, through SBERA’s Investment Committee, select investment managers for 
the common and collective trust portfolio. A professional advisory firm is retained
by the Investment Committee to provide allocation analysis and performance 
measurement and to assist with manager searches. The target allocation mix calls
for an equity-based investment deployment range from 55% to 75% of total 
portfolio assets. The remainder of the portfolio is allocated to fixed income. The
overall investment objective is to diversify equity investments across a spectrum 
of investment types (e.g., small cap, large cap, international, etc.) and styles 
(e.g., growth, value, etc.). The Company closed the plan to employees hired 
after March 31, 2006.

Prior to 2008, the measurement date for the Plan was September 30 for each 
year. Beginning in 2008, the measurement date was changed to December 31 in
accordance with SFAS No. 158. The benefits expected to be paid in each year from
2009 to 2013 are $720,000, $752,000, $774,000, $910,000 and $934,000,
respectively. The aggregate benefits expected to be paid in the five years from
2014 to 2018 are $5,830,000. The Company plans to contribute $1,275,000 
to the Plan in 2009.

The weighted-average asset allocation of pension benefit assets was:

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 and participants are required to contribute to its cost. Under the Supplemental Plan, each participant will receive a retirement benefit based 
on compensation and length of service. Individual life insurance policies, which are owned by the Company, are purchased covering the lives of each participant. Effective
December 31, 2006, the Company adopted SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — An Amendment of FASB
Statements No. 87, 88, 106 and 132(R).” The Company recorded an additional $2,158,000 net pension liability adjustment, through stockholders’ equity, as a result of 
this adoption.

Prior to 2008, the measurement date for the Supplemental Plan was September 30 for each year. Beginning in 2008, the measurement date was changed to December 31 in
accordance with SFAS No. 158. The benefits expected to be paid in each year from 2009 to 2013 are $1,034,000, $1,042,000, $1,049,000, $1,051,000 and $1,045,000,
respectively. The aggregate benefits expected to be paid in the five years from 2014 to 2018 are $6,481,000.

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

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
$265,000 for 2008, $229,000 for 2007 and $210,000 for 2006. 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. There were no payments under this plan for 2006, 2007 and 2008. Discretionary bonus expense amounted to 
$348,000, $154,000, and $0, in 2008, 2007, and 2006, respectively.

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

Commitments and Contingencies
A number of legal claims against the Company arising in the normal course of
business were outstanding at December 31, 2008. 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.

17.

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 notational 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-balance-sheet instruments. Financial instruments with off-balance-sheet 
risk at December 31 are as follows:

Contract or Notational Amount

(dollars in thousands)

Financial instruments whose contract

amount represents credit risk:

Commitments to originate 

1-4 family mortgages

Standby and commercial letters of credit

Unused lines of credit

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.

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 nonfinancial instruments. Accordingly, the aggregate fair value amounts
presented do not represent the underlying value of the Company.

CASH AND CASH EQUIVALENTS
The carrying amounts reported in the balance sheet for cash and cash 
equivalents approximate the fair values of these assets because of the short-term
nature of these financial instruments.

SHORT-TERM INVESTMENTS
The fair value of short-term investments is estimated using the discounted value
of contractual cash flows. The discount rate used is estimated based on the rates
currently offered for short-term investments of similar remaining maturities.

SECURITIES HELD-TO-MATURITY AND SECURITIES AVAILABLE-FOR-SALE 
The fair value of these securities is estimated based on prices published in 
financial newspapers or received from pricing services, or bid quotations received
from securities dealers.

LOANS
For variable-rate loans, which 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.

ACCRUED INTEREST RECEIVABLE AND PAYABLE
The carrying amounts for accrued interest receivable and payable approximate
fair values because of the short-term nature of these financial instruments.

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’08

DEPOSITS
The fair value of deposits, with no stated maturity, is equal to the carrying amount. The fair value of time deposits is based on the discounted value of contractual cash
flows, applying interest rates currently being offered on the deposit products of similar maturities. The fair value estimates for deposits do not include the benefit that
results from the low-cost funding provided by the deposit liabilities compared to the cost of alternative forms of funding (“deposit base intangibles”).

REPURCHASE AGREEMENTS AND OTHER BORROWED FUNDS
The fair value of repurchase agreements and 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.

OFF-BALANCE-SHEET INSTRUMENTS
The fair values of the Company’s unused lines of credit and unadvanced portions of construction loans, commitments to originate and sell loans and standby 
letters of credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the
counterparties’ credit standing.

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.

Report of Independent Registered Public Accounting Firm

Century Bancorp, Inc. AR ’08

KPMG LLP

Independent Registered Public Accounting Firm
99 High Street
Boston, Massachusetts 02110

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, 2008 and 2007, and the related 
consolidated statements of income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2008. 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, 2008 and 2007, and the results of their operations and their cash flows for each of the years in the three-year period ended
December 31, 2008, 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, 2008, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO), and our report dated February 24, 2009 expressed an unqualified opinion on the effectiveness of the Company’s
internal control over financial reporting.

Century Bancorp, Inc. AR ’08

KPMG LLP

99 High Street
Boston, Massachusetts 02110

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, 2008, based on criteria established in Internal Control —
Integrated Framework 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, 2008, based on criteria
established in Internal Control — Integrated Framework 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, 2008 and 2007, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the
years in the three-year period ended December 31, 2008, and our report dated February 24, 2009 expressed an unqualified opinion on those consolidated 
financial statements.

Management’s Report on Internal Control Over Financial Reporting

Century Bancorp, Inc. AR ’08

CENTURY BANCORP, INC.

400 Mystic Avenue
Medford, Massachusetts 02155

We, together with the other members 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, 2008. 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. Based on our assessment, we believe that, as of December 31, 2008, 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 45.
