Family focused. 
It defines our values and 
drives our success.  

CA14518 Cover  2/27/08  9:03 AM  Page 2

A   W O R D   F R O M   O U R   C H A I R M A N

As a family-run business, the values that define our company are not 
just part of our company culture. They are the principles that guide 
our decisions and help us position our company for sustained growth.
Our prudent approach and long-term view proved to be the right
course in 2007 as we steered clear of the pitfalls faced by so many
other financial institutions.  

Marshall M. Sloane

The last major credit crisis I witnessed was in the early nineties, over 15 years ago. Century 
weathered that storm, while watching scores of peer institutions fail or be compelled to merge.
The current credit crisis is again predicated on real estate, but in a different securitized structure.
Regardless of the mechanics, we believed then, and we believe now, that banks will lose money
when they make the mistake of decentralized credit authority and allow unsupervised geographic
lending expansion.  

While our loan policies and choice to remain focused within our market area may have appeared
overly conservative several years ago, our decisions have served us well. We chose not to get 
involved in an overheated market of inflated appraisals and aggressive brokers. We have always
tightly controlled loan authorities and customer geography because we believe there is no 
substitute for local market knowledge. Our risk management philosophy has worked for us since
our inception, and it is one of the reasons we have consistently paid a dividend on our stock 
for the last 34 years.

By staying true to our 
own family’s values, we continue to 
build our franchise value.  

I watch with amazement as the “giants” of our industry replenish their depleted capital, following
the sub-prime charge-offs, with huge foreign equity infusions. Little is said about the dramatic 
dilution of value for existing shareholders in those recapitalizations. We have always been sensitive
to maintaining and creating value for our loyal long-term shareholders. This latest crisis is 
one more example of how being guided by our values and our independent thinking has proven 
to be in our shareholders’ best interests. Our shareholders are always foremost in our thoughts 
and plans.

As we approach our 40th anniversary, I am confident that Century’s strategy will 
hold true for the future.

Sincerely,

Marshall M. Sloane
Founder and Chairman

Jonathan and Barry Sloane

D E A R   F E L L O W   S H A R E H O L D E R S :

2007 was a year of much improved performance for Century Bancorp. Building on our strong 
foundation, we grew our income, increased deposits and achieved growth across a range 
of business lines despite challenging economic conditions.

A solid performance.
Net income for the year ended December 31, 2007 rose 68% to $7,864,000, or $1.42 per 
diluted share, compared to $0.84 per diluted share in 2006. Our book value per share grew
11.2% to $21.43 at December 31, 2007, compared to $19.28 at year-end 2006. Total 
stockholders equity at year-end stood at over $118 million.

In a year when profitable deposit growth was exceptionally difficult due to a nearly flat, and 
frequently inverted, yield environment, we attracted new deposits and built on the strength 
of our customer relationships. We offer a distinct alternative to the “giant” banks as customers
turn to us for a personalized relationship from the locally controlled bank they know and trust.
In 2007, we grew “core” branch deposits 6.6%, or $23 million, and we increased total assets
2.2%, year-over-year, to $1.7 billion.

Our net interest margin improved to 2.65% during 2007, up from 2.40% in 2006. Our 
efficiency ratio also improved to 77.5% in 2007, down from 83.5% in 2006. While both ratios
are still below our goals, we continue to implement strategies to achieve both higher loan yields
and lower operating expenses—while striving to attain the optimum level of efficiency in the
context of providing the highest service quality and regulatory compliance.

Growing our business.
The competition for quality middle-market business loans continues to be intense, and 
developing credit relationships remained a focus in 2007. While maintaining credit quality
through our disciplined and prudent approach to lending, we held the total portfolio roughly
even, year-over-year, at $726 million. With our local market knowledge and experience, our 
Business Development Officers and Branch Managers grew our small business loans 7.4% 
in 2007 through originations of $28.4 million, expanding the total small business portfolio 
to $67 million. 

The Institutional Services Group added eight new major lockbox relationships in 2007, 
growing the total number of items processed to over 23 million, up some 5% from 2006. 

CA14518 Editorial:Layout 1  2/27/08  11:15 AM  Page 2

This achievement is especially noteworthy as the number of items processed industry-wide 
continues to decline with the shift to electronic payments. To that end, we grew our electronic
payment activity by 14.2% in 2007 to over 3.2 million ACH transactions. The Institutional 
business made a major contribution to our 23% increase in other operating income, reaching 
a record level of $13.9 million.

While some banks were shaken 
to their core in 2007, we stayed true 
to our values and prospered.

True to our values.
As important as what we did in 2007, is what we did not do; and that was exploit the perceived
opportunities in sub-prime lending or investing. Century has avoided the sub-prime mortgage
disaster that is shaking the banking industry.

Time and again over the past decade we were approached by the mortgage industry 
with proposals to join the flood of banks into sub-prime lending, and each time we came 
to a head-shaking conclusion that, regardless of the potential profits, these transactions 
were predatory, and largely unsuitable, to our clients. We saw clearly that unsupported 
and inappropriate levels of debt would ultimately fail the borrowing families and their 
lending institutions.

We believe that our rejection of sub-prime lending as a profit opportunity is yet another 
way that the family values that guide our company make a difference for the soundness

of our balance sheet and fiscal safety of our customers. As we review the 2007 performance of our
regional bank peer group, it is clear that our commitment to sound principles of risk management
and the value of long-term customer relationships has proven itself once again.

Successful community banking is an incremental business of careful execution to achieve 
consistent earnings and asset growth. We are very comfortable with the business strategy cast 
by our Founder and Chairman in 1969: the 2007 sub-prime crisis was a clear validation of 
our continuing shared values.

Challenges and opportunities.
The economic conditions ahead will likely provide earnings challenges, yet may also yield 
opportunities for client and business acquisitions. Guided by our core values, with the flexibility 
to nimbly react to changing business and economic conditions, we believe we are well positioned
to navigate this latest business cycle. 

As always, we remain focused on our core communities and our relationships with both the 
business and not-for-profit sectors. We will continue to seek ways to improve service, lower costs,
and ensure prudent risk management. We will continue to invest in our communities as a valued
neighbor and resource. We encourage our officers to devote time and effort to local charitable 
endeavors, and we financially support their efforts as resources allow.

Century Bank is, most of all, a collection of highly skilled professionals whose knowledge of their
clients and communities is the core of our franchise. We thank our employees for their hard work
and dedication in making our success possible, and we thank you, our shareholders, for your trust. 

We are optimistic about the year ahead and look forward to continued success.

Sincerely,

Barry R. Sloane

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. The Company
had total assets of $1.7 billion at December 31, 2007. The Company presently
operates 21 banking offices in 16 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
interest paid on deposits and borrowings. The results of operations are also 
affected by the level of income/fees from loans, deposits, as well as operating
expenses, the provision for loan losses, the impact of federal and state income
taxes and the relative levels of interest rates and economic activity.

The Company offers a wide range of services to commercial enterprises, state 
and local governments and agencies, non-profit organizations and individuals. It
emphasizes service to small and medium-sized businesses and retail customers in 
its market area. 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 supported
by Linsco/Private Ledger Corp., a full service securities brokerage business.

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
39% of the 351 cities and towns in Massachusetts.

03

The Company had net income of $7,864,000 for the year ended December 31,
2007, compared with net income of $4,688,000 for the year ended December
31, 2006 and net income of $6,880,000 for the year ended December 31, 2005.
Basic earnings per share were $1.42 in 2007, compared to $0.85 in 2006 and
$1.24 in 2005. Diluted earnings per share were $1.42 in 2007, compared to
$0.84 in 2006 and $1.24 in 2005. Included in income for 2007 is $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, 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 the loan yield due to an increase in prepayment fees, 

particularly in the second quarter of 2007, and

• The maturity of lower-yielding investment securities.

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.

In addition, a great deal of emphasis has been placed on cost control during
2007 as demonstrated by the increase of 0.1% in operating expenses for the
year ended December 31, 2007.

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. During 2005 and 2006, the U.S. economy experienced a flattening and
subsequent inversion of the yield curve, which means that the spread between 

CA14518_Financials  2/28/08  2:47 PM  Page 7

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

the long-term and short-term yields has decreased or inverted. During 2007,
rates have fallen and the yield curve has steepened somewhat. This has 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 $1,680,281,000 at December 31, 2007, an increase of 2.2%
from total assets of $1,644,290,000 on December 31, 2006.

On December 31, 2007, stockholders’ equity totaled $118,806,000, compared
with $106,818,000 on December 31, 2006. Book value per share increased 
to $21.43 at December 31, 2007 from $19.28 on December 31, 2006.

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.

During 2007, the Company entered into a lease agreement to open a branch
located on Riverside Avenue in Medford, Massachusetts. The branch is scheduled
to open during the second quarter of 2008. 

On August 17, 2007, the Company sold the building which houses one of its
branches located at 55 High Street, Medford, Massachusetts for $1.5 million 
at market terms. The Bank is relocating this branch to 1 Salem Street (formerly
3 Salem Street), Medford, Massachusetts. This sale resulted in a gain 
of $1,321,000.

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.

CRITICAL ACCOUNTING POLICIES 
Accounting policies involving significant judgments and assumptions by 
management, which have, or could have, a material impact on the carrying value
of certain assets and impact income, are considered critical accounting policies.
The Company considers the following to be its critical accounting policies:
allowance for loan losses and impairment of investment securities. There have
been no significant changes in the methods or assumptions used in the 
accounting policies that require material estimates and assumptions.

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

Century Bancorp, Inc. AR ’07

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 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 loss experience, 
as well as regulatory guidelines.

Specific allowances for loan losses entails 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 non-accrual 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.

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 write-down 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 hinder
its ability to make future scheduled interest and principal payments on a timely
basis or whether there was downgrade in ratings by rating agencies.

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

Century Bancorp, Inc. AR ’07

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 Enterprises, mortgage-backed securities, state, county, municipal 
securities, foreign debt securities, other marketable equities and Federal Home Loan Bank (“FHLB”) stock.

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, 2007 totaled $403,635,000 and include gross unrealized gains of $1,728,000 and gross 
unrealized losses of $2,077,000. A year earlier, securities available-for-sale were $415,481,000 including gross unrealized gains of $221,000 and unrealized losses 
of $8,447,000. In 2007, the Company recognized gross gains of $153,000 on the sale of one stock. In 2006, the Company recognized no net gains or losses 
on the sale of available-for-sale securities.

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, 2007 are carried at their amortized cost of $183,710,000 and exclude gross unrealized gains of $131,000 and gross unrealized
losses of $2,137,000. A year earlier, securities held-to-maturity totaled $265,712,000 excluding gross unrealized gains of $76,000 and gross unrealized losses 
of $7,368,000.

during 2007 with gross proceeds of $336,000 resulting in a gain of $153,000.

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 is generally dependent on the
health of the real estate market in the borrowers’ geographic areas and the general economy.

The Company’s commercial and industrial (C&I) loan customers represent various small and middle market established businesses involved in manufacturing, distribution,
retailing and services. Most clients are privately owned with markets that range from local to national in scope. Many of the loans to this segment are secured by liens 
on corporate assets and the personal guarantees of the principals. The regional economic strength or weakness impacts the relative risks in this loan category. There is
little concentration 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 re-write or otherwise extend the loan at prevailing interest rates. During recent years, the Bank has emphasized non-residential 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
non-residential and residential mortgages.

Residential real estate (1-4 family) includes two categories of loans. Included in residential real estate are approximately $9,503,000 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 are mostly 1-4 family residential properties located in the Bank’s market area. General underwriting criteria are largely
the same as those used by Federal National Mortgage Association (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%.

The Bank intends to maintain a market for construction loans, principally for smaller local residential projects or an owner-occupied commercial project. Individual 
consumer residential home construction loans are also extended on a similar basis.

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, 2007, the Company was obligated to advance a total of $27,294,000 to complete projects under construction.

At December 31, 2007, impaired loans of $75,000 had specific reserves of $75,000. There were no impaired loans with specific reserves from December 31, 2003
through December 31, 2006.

The Company was servicing mortgage loans sold to others without recourse of approximately $559,000, $798,000, $1,078,000, $1,538,000 and $2,397,000 
at December 31, 2007, 2006, 2005, 2004 and 2003, respectively. Additionally, the Company services mortgage loans sold to others with limited recourse. 
The outstanding balance of these loans with limited recourse was approximately $65,000, $72,000, $80,000, $86,000 and $183,000 at December 31, 2007,
2006, 2005, 2004 and 2003, respectively.

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 non-accrual 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.

Non-accrual 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 $14,117,000 and $20,779,000 at December 31, 2007 and 2006, respectively, of potential
problem 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, 2007, although such values can fluctuate with changes in the economy 
and the real estate market.

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 due to an increase in commercial 
loan charge-offs.

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:

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

Century Bancorp, Inc. AR ’07

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. In prior years, 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. 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.

The following table sets forth the average balances of the Bank’s deposits for the periods indicated.

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 borrowing from the FHLB totaled $289,250,000, an increase of $167,500,000
from the prior year. The Bank’s remaining term borrowing capacity at the FHLB at December 31, 2007 was approximately $31,452,000. In addition, the Bank has a
$14,500,000 line of credit with the FHLB. See note 10 “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 twenty 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 $85,990,000,
a decrease of $970,000 from the prior year. See note 9 “Securities Sold Under Agreements to Repurchase” for a schedule, including their interest rates and other informa-
tion.

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 increased 6.6% in 2007 to
$39,203,000, compared with $36,763,000 in 2006. The increase in net interest income for 2007 was mainly due to a 10.4% or a twenty-five 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 2.65% in 2007 from 2.40% in 2006, 
which had decreased from 2.58% in 2005. 

The following table sets forth the distribution of the Company’s average assets, liabilities and stockholders’ equity, and average rates earned or paid on a fully taxable

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

Century Bancorp, Inc. AR ’07

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 $1,479,349,000 in 2007, a decrease of $55,568,000 or 3.6% from the average in 2006, which was 1.0% lower than the average in 2005.
Total average securities, including securities available-for-sale and securities held-to-maturity, were $621,546,000, a decrease of 19.6% from the average in 2006. The
decrease in securities volume was mainly attributable to an increase in pricing discipline relating to deposits that resulted in a smaller average balance sheet. A decrease 
in securities balances resulted in lower securities income, which decreased 13.8% to $23,548,000. Total average loans increased 0.3% to $725,903,000 after increasing
$82,722,000 in 2006. The primary reason for the increase in loans was due in large part to an increase in small business lending. The increase in loan volume and increases
in loan rates resulted in higher loan income, which increased by 2.8% or $1,436,000 to $52,902,000. Total loan income was $41,274,000 in 2005.

The Company’s sources of funds include deposits and borrowed funds. On average, deposits showed a decrease of 4.3% or $53,898,000 in 2007 after increasing by 2.6%
or $31,760,000 in 2006. Deposits decreased in 2007 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 decreased by 12.3% in 2007 following a decrease of 14.8% in 2006.
The majority of the Company’s borrowed funds are borrowings from the FHLB and retail repurchase agreements. Borrowings from the FHLB decreased by approximately
$22,801,000 and retail repurchase agreements increased by $18,953,000. Interest expense totaled $43,805,000 in 2007, a slight decrease of $139,000 or 0.3% 
from 2006 when interest expense increased 33.9% from 2005. The decrease in interest expense is primarily due to deposit pricing discipline.

Provision for Loan Loss 
The provision for loan losses was $1,500,000 in 2007, compared with $825,000 in 2006 and $600,000 in 2005. 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 2007 primarily as a result of an increase in net charge-offs during the year.

The allowance for loan losses was $9,633,000 at December 31, 2007, compared with $9,713,000 at December 31, 2006. Expressed as a percentage of outstanding
loans at year-end, the allowance was 1.33% in 2007 and 1.32% in 2006. This ratio increased mainly as a result of a small decrease in the loan portfolio.

Nonperforming loans, which include all non-accruing loans, totaled $1,312,000 on December 31, 2007, compared with $135,000 on December 31, 2006.
Nonperforming loans increased primarily as a result of three consumer mortgages totaling $938,000.

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

Century Bancorp, Inc. AR ’07

Other Operating Income 
During 2007, 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. The
brokerage service was previously offered through IFMG, also 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 who 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 2007 was $13,948,000, an increase of
$2,583,000 or 22.7% compared to 2006. This increase followed an increase 
of $392,000 or 3.6% in 2006, compared to 2005. 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 $7,579,000 in 2007, increased
$877,000 compared to 2006. This followed an increase of $856,000 compared
to 2005. Service charges on deposit accounts increased mainly because of
increases in fees and an increase in overdraft charges. Lockbox revenues totaled
$2,956,000, up $184,000 in 2007 following a decrease of $35,000 in 2006. 
This increase was mainly attributable to an increase in the customer base. 
Other income totaled $1,687,000, down $55,000 in 2007 following a decrease
of $116,000 in 2006. 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 ATM machines. The decrease in 2006 was mainly attributable to 
a decrease in the growth of cash surrender values by $697,000 due to a decline
in the policy returns 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.

Operating Expenses 
Total operating expenses were $40,255,000 in 2007, compared to
$40,196,000 in 2006 and $40,318,000 in 2005.

Salaries and employee benefits expenses increased by $728,000 or 3.1% 
in 2007, after decreasing by 1.6% in 2006. The increase in 2007 was mainly
attributable to an increase in staff levels, merit increases in salaries and increases
in health insurance costs. The decrease in 2006 was mainly attributable to 
the retirement of the former Chief Executive Officer offset somewhat by 
an increase in pension expense and health insurance costs. 

13

Occupancy expense decreased by $55,000 or 1.4% in 2007, following an
increase of $109,000 or 2.9% in 2006. The decrease in 2007 was primarily
attributable to an increase in rental income. The increase in 2006 was primarily
attributable to an increase in utility rates. Equipment expense decreased by
$86,000 or 2.8% in 2007, following an increase of $56,000 or 1.9% in 2006.
The decrease in 2007 was primarily attributable to a decrease in depreciation
expense. The increase in 2006 was primarily attributable to depreciation 
associated with the addition of capital expenditures. Other operating expenses
decreased by $528,000 in 2007, which followed a $95,000 increase in 2006.
The decrease in 2007 was primarily attributable to a decrease in bank 
processing charges and legal expense. The increase in 2006 was primarily 
attributable to an increase in contributions. 

Provision for Income Taxes 
Income tax expense was $3,532,000 in 2007, $2,419,000 in 2006 and
$3,166,000 in 2005. The effective tax rate was 31.0% in 2007, 34.0% in 2006
and 31.5% in 2005. The decrease in the effective tax rate for 2007 was mainly
attributable to a higher level of non-taxable income. The increase in the effective
tax rate for 2006 was primarily the result of a decrease in non-taxable income.
The federal tax rate was 34% in 2007, 2006 and 2005.

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, and 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 exposures to 
differential changes in interest rates between assets and liabilities is an interest 
rate risk management test.

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

Change in Interest Rates
(in Basis Points)

Percentage Change in
Net Interest Income(1)

+300
+200
+100
–100
–200
–300

(0.2)%
(0.4)% 
(0.7)% 
(2.5)%
(3.8)%
(4.9)%

(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.

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

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 $299,901,000 on December 31, 2007, 
compared with $159,668,000 on December 31, 2006. In each of these 
two years, deposit and borrowing activity has generally been adequate 
to support asset activity.

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.

Century Bancorp, Inc. AR ’07

Capital Adequacy 
Total stockholders’ equity was $118,806,000 at December 31, 2007, compared
with $106,818,000 at December 31, 2006. The increase in 2007 was primarily
the result of earnings and a decrease in accumulated other comprehensive 
loss less dividends paid. The decrease in accumulated other comprehensive loss
was mainly attributable to an improvement of $4,900,000 in the net unrealized
loss on the Company’s available-for-sale portfolio, and an improvement of
$1,346,000 in the additional pension liability, 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 16.46%
and 13.02%, respectively, and total capital-to-risk assets ratio of 17.51% and
14.08%, respectively, at December 31, 2007. 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, 2007, the Company and the Bank
exceeded this requirement with leverage ratios of 9.56% and 7.56%, respectively.

Contractual Obligations, Commitments, and Contingencies

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 ’07

The Company’s exposure to credit loss in the event of non-performance 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:

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 commercial 
mortgage loans, certain private equity investments, distressed debt, non-investment
grade residual interests in securitizations, as well as certain highly structured OTC
derivative contracts.

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.

Recent Accounting Developments 
In September 2006, the Financial Accounting Standards Board (“FASB”) issued
SFAS 157, “Fair Value Measurements,” which among other things, requires enhanced
disclosures about financial instruments carried at fair value. SFAS 157 is effective
for fiscal years beginning after November 15, 2007. 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 values have been
derived using a model where inputs to the model are directly observable in the
market, or can be derived principally from or corroborated by observable market
data, and instruments that are fair valued using other financial instruments, the
parameters of which can be directly observed. Instruments which are generally
included in the 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 

15

The Company is currently evaluating the impact SFAS 157 will have upon 
disclosures upon adoption.

In February 2007, the FASB issued Statement of Financial Accounting Standard 
No. 159 (“SFAS 159”), “The Fair Value Option for Financial Assets and Financial
Liabilities,” 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.

In March 2007, the FASB ratified the consensus reached by the Emerging Issues
Task Force (“EITF”) on EITF 06-10, “Accounting for Deferred Compensation and
Postretirement Benefit Aspects of Collateral Assignment Split-Dollar Life Insurance
Arrangements.” EITF 06-10 will require employers to recognize a liability for the
postretirement benefit related to a collateral assignment split-dollar life insurance
arrangement if the employer remains subject to the risks or rewards associated
with the underlying insurance contract (in the postretirement period) that 
collateralizes the employer’s asset. Additionally, an employer should recognize and
measure an asset based on the nature and substance of the collateral assignment
split-dollar life insurance arrangement by assessing what future cash flows the
employer is entitled to, if any, as well as the employer’s obligation and ability to
repay the employer. The employer’s asset should be limited to the amount of the
cash surrender value of the insurance policy, unless the arrangement requires the
employee (or retiree) to repay the employer irrespective of the amount of the cash
surrender value of the insurance policy (and assuming the employee (or retiree) 
is an adequate credit risk), in which case the employer should recognize the value
of the loan including accrued interest, if applicable. EITF 06-10 is effective for 
fiscal years beginning after December 15, 2007, earlier application permitted.
Entities should recognize the effects of applying EITF 06-10 through either 
a change in accounting principle through a cumulative-effect adjustment to
retained earnings in the statement of financial position as of the beginning 
of the year of adoption or through a change in accounting principle through 
retrospective application to all prior periods. The Company anticipates the impact
of EITF 06-10 to be immaterial to the Company’s consolidated financial statements.

In December 2007, the FASB issued SFAS 141R, "Business Combinations." 
SFAS 141R replaces FASB Statement No. 141, “Business Combinations,” but retains
the fundamental requirements in Statement 141 that the acquisition method of
accounting (which Statement 141 called the purchase method) be used for all 
business combinations and for an acquirer to be identified for each business 
combination. It also retains the guidance in Statement 141 for identifying and 
recognizing intangible assets separately from goodwill. However, SFAS 141R's scope
is broader than that of Statement 141. SFAS 141R applies prospectively to business
combinations for which the acquisition date is on or after the beginning of the first
annual reporting period beginning on or after December 15, 2008. Earlier adoption
is prohibited. For any business combinations entered into by the Company 
subsequent to January 1, 2009, the Company will be required to apply the 
guidance in SFAS 141R.

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. Ill (“CSII III”) and Century Financial Services
Inc. (“CFSI”). CSII, CSII II, 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 interest that may be
charged thereon, and limitations on the types of investments that may be made
and the types of services that may be offered. Various consumer laws and 
regulations also affect the operations of the Bank. In addition to the impact 
of regulation, commercial banks are affected significantly by the actions of the
Federal Reserve Board as it attempts to control the money supply and credit 
availability in order to influence the economy. All aspects of the Company’s 
business are highly competitive. The Company faces aggressive competition from
other lending institutions and from numerous other providers of financial services.
The Company has one reportable operating segment.

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

Material estimates that are susceptible to change in the near-term relate to 
the allowance for loan losses. Management believes that the allowance for loan
losses is adequate based on 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.

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’07

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 write-down 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.

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 non-accrual loans.
When a loan is placed on non-accrual, 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. Non-accrual 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 non-accrual 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.

The Bank accounts for impaired loans, except those loans that are accounted 
for at fair value or 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.

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.

STOCK OPTION ACCOUNTING 
Prior to January 1, 2006, the Company accounted for its stock-based plans 
under the recognition and measurement provisions of Accounting Principles Board
Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), and 
related Interpretations, as permitted by SFAS No. 123, “Accounting for Stock-Based
Compensation” (“SFAS 123”). No compensation cost was recognized for stock
options in the Consolidated Statement of Income for the periods ended on or
prior to December 31, 2005, as options granted under those plans had an exercise
price equal to or greater than the market value of the underlying common stock 
on the date of the grant.

Effective January 1, 2006, the Company adopted the fair value recognition 
provisions of SFAS 123R for all share-based payments, using the modified-
prospective transition method. In accordance with the modified-prospective
transition method, the Company’s Consolidated Financial Statements for prior
periods have not been restated to reflect, and do not include, the impact of
SFAS 123R. Upon adoption of SFAS 123R, the Company elected to retain its
method of valuation for share-based awards granted using 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 non-qualified
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

21

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 non-qualified 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 94,787
shares of Class A common stock exercisable at December 31, 2007.

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 non-cash 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 non-cash 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.

Had compensation cost for the Company’s stock option plans been determined
based on the fair value at the grant date, the Company’s net income and earnings
per share for the year ended December 31, 2005 would have been reduced to 
the pro forma amounts indicated in the following table:

In determining the pro forma amounts, the fair value of each option grant was

1.59 %

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 2007.

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 Financial Accounting Standards Board (“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 operation 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 at 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 

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’07

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 requires the Company to measure plan assets and benefit 
obligations as of the date of the Company’s fiscal year-end effective for 
fiscal years ending after December 15, 2008.

RECENT ACCOUNTING DEVELOPMENTS 
In September 2006, the Financial Accounting Standards Board (“FASB”) issued 
SFAS 157, “Fair Value Measurements,” which among other things, requires enhanced
disclosures about financial instruments carried at fair value. SFAS 157 is effective for
fiscal years beginning after November 15, 2007. 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 values have been derived
using a model where inputs to the model are directly observable in the market, 
or can be derived principally from or corroborated by observable market data, and
instruments that are fair valued using other financial instruments, the parameters 
of which can be directly observed. Instruments which are generally included in the
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 commercial mortgage
loans, certain private equity investments, distressed debt, non-investment grade
residual interests in securitizations, as well as certain highly structured OTC 
derivative contracts.

The Company is currently evaluating the impact SFAS 157 will have upon disclosures
upon adoption.

In February 2007, the FASB issued Statement of Financial Accounting Standard
No. 159 (“SFAS 159”), “The Fair Value Option for Financial Assets and Financial
Liabilities,” 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.

In March 2007, the FASB ratified the consensus reached by the Emerging Issues Task Force (“EITF”) on EITF 06-10, “Accounting for Deferred Compensation and
Postretirement Benefit Aspects of Collateral Assignment Split-Dollar Life Insurance Arrangements.” EITF 06-10 will require employers to recognize a liability for the 
postretirement benefit related to a collateral assignment split-dollar life insurance arrangement if the employer remains subject to the risks or rewards associated with the
underlying insurance contract (in the postretirement period) that collateralizes the employer’s asset. Additionally, an employer should recognize and measure an asset based
on the nature and substance of the collateral assignment split-dollar life insurance arrangement by assessing what future cash flows the employer is entitled to, if any, as 
well as the employer’s obligation and ability to repay the employer. The employer’s asset should be limited to the amount of the cash surrender value of the insurance policy,
unless the arrangement requires the employee (or retiree) to repay the employer irrespective of the amount of the cash surrender value of the insurance policy (and 
assuming the employee (or retiree) is an adequate credit risk), in which case the employer should recognize the value of the loan including accrued interest, if applicable.
EITF 06-10 is effective for fiscal years beginning after December 15, 2007, earlier application permitted. Entities should recognize the effects of applying EITF 06-10
through either a change in accounting principle through a cumulative-effect adjustment to retained earnings in the statement of financial position as of the beginning 
of the year of adoption or through a change in accounting principle through retrospective application to all prior periods. The Company anticipates the impact of 
EITF 06-10 to be immaterial to the Company’s consolidated financial statements.

In December 2007, the FASB issued SFAS 141R, “Business Combinations.” SFAS 141R replaces FASB Statement No. 141, “Business Combinations,” but retains the fundamental
requirements in Statement 141 that the acquisition method of accounting (which Statement 141 called the purchase method) be used for all business combinations and 
for an acquirer to be identified for each business combination. It also retains the guidance in Statement 141 for identifying and recognizing intangible assets separately from
goodwill. However, SFAS 141R's scope is broader than that of Statement 141. SFAS 141R applies prospectively to business combinations for which the acquisition date is on
or after the beginning of the first annual reporting period beginning on or after December 15, 2008. Earlier adoption is prohibited. For any business combinations entered
into by the Company subsequent to January 1, 2009, the Company will be required to apply the guidance in SFAS 141R.

Cash and Due from Banks
The Company is required to maintain a portion of its cash and due from banks as a reserve balance under the Federal Reserve Act. Such reserve is calculated based
upon deposit levels and amounted to $1,909,000 at December 31, 2007 and $805,000 at December 31, 2006.

The weighted average remaining life of investment securities available-for-sale at December 31, 2007 and 2006 was 2.2 and 2.1 years, respectively. Included in the
weighted average remaining life calculation at December 31, 2007 and 2006 were $113,160,000 and $10,000,000, respectively, of U.S. Government Sponsored
Enterprises obligations that are callable at the discretion of the issuer. These call dates were not utilized in computing the weighted average remaining life. The actual
maturities, which were used in the table above, of mortgage-backed securities will differ from the contractual 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, 2007. This table shows the unrealized

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 is relocating this branch to 1 Salem Street (formerly 3 Salem Street), Medford, Massachusetts. This property will be leased from an entity affiliated with
Marshall M. Sloane, Chairman of the Board of the Company. The lease is for a period of fifteen years. The annual base rent amount will be $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.

Until such time as 1 Salem Street is opened as a branch, 55 High Street has been leased to the Bank as a tenant-at-will at market terms. It is anticipated that the 
new branch will be opened during the second or third quarter of 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 $1,349,000, $1,113,000 and $1,076,000 for the years ended December 31, 2007, 2006 and 2005, respectively. Rental income
approximated $351,000, $69,000 and $61,000 in 2007, 2006 and 2005, respectively.

Future minimum rental commitments for noncancelable operating leases with initial or remaining terms of one year or more at December 31, 2007 were as follows:

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 share for 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 2007, 2006 and 2005 was an increase of 4,246, 9,756 and 17,807
shares, respectively.

STOCK OPTION PLAN 
During 2000 and 2004, common stockholders of the Company approved stock option plans (the “Option Plans”) that provides 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 non-qualified
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 non-qualified 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 94,787 options exercisable at December 31, 2007.

Stock option activity under the plan is as follows:

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’07

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, 2007, that the Bank and the Company meets all capital adequacy requirements to which it is subject.

As of December 31, 2007, 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.
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, 2007. 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
The Company has a Qualified Defined Benefit Pension Plan (the “Plan”), which 
had been offered to all employees reaching minimum age and service requirements.
In 2006, the Bank became a member of the Savings Bank Employees Retirement
Association (“SBERA”) within which it then began maintaining the Qualified
Defined Benefit Pension Plan. SBERA offers a common and collective trust as 
the underlying investment structure for 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, 
performance measurement and to assist with manager searches. 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.

The measurement date for the Plan is September 30 for each year. The benefits
expected to be paid in each year from 2008-2012 are $604,000, $693,000,
$727,000, $780,000 and $925,000. The aggregate benefits expected to be 
paid in the five years from 2013-2017 are $5,720,000. The Company plans 
to contribute $1,387,000 to the Plan in 2008.

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. An increase 
in recognized net losses resulted in an increase in the cost of the Supplemental Plan in 2006. 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.

The measurement date for the Supplemental Plan is September 30 for each year. The benefits expected to be paid in each year from 2008-2012 are $1,033,000, $1,029,000,
$1,029,000, $1,041,000 and $1,043,000. The aggregate benefits expected to be paid in the five years from 2013-2017 are $5,843,000.

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
$229,000 for 2007, $210,000 for 2006 and $217,000 for 2005. Administrative costs associated with the plan are absorbed by the Company.

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, 2007. 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 operation.

15.

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.

SECURITIES HELD-TO-MATURITY AND SECURITIES AVAILABLE-FOR-SALE 
The fair value of these securities, excluding certain state and municipal securities
whose fair value is estimated at book value because they are not readily 
marketable, 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, that reprice frequently and with no significant change 
in credit risk, fair values are based on carrying amounts. The fair value of other
loans is estimated using discounted cash flow analysis, based on interest rates
currently being offered for loans with similar terms to borrowers of similar credit
quality. Incremental credit risk for nonperforming loans has been considered.

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. 

34

CA14518_Financials  2/28/08  2:47 PM  Page 38

Notes to Consolidated Financial Statements

Century Bancorp, Inc. AR ’07

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. 

The carrying amounts and fair values of the Company’s financial instruments at December 31 are as follows:

(dollars in thousands)

Financial assets:

Cash and cash equivalents

Securities available-for-sale

Securities held-to-maturity

Net loans

Accrued interest receivable

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.

KPMG LLP

Independent Registered Public Accounting Firm

Boston, Massachusetts 02110

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

Century Bancorp, Inc. AR ’07

We have audited the accompanying consolidated balance sheets of Century Bancorp, Inc. and subsidiary as of December 31, 2007 and 2006, 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, 2007. 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 subsidiary as of December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the years in the three-year period ended 
December 31, 2007, 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, 2007, 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 26, 2008 expressed an unqualified opinion on the effectiveness of the 
Company’s internal control over financial reporting.

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

We have audited Century Bancorp, Inc.’s internal control over financial reporting as of December 31, 2007, 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, 2007, 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, 2007 and 2006, 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, 2007, and our report dated February 26, 2008 expressed an unqualified opinion on those consolidated financial
statements.

Management’s Report on Internal Control Over Financial Reporting

Century Bancorp, Inc. AR ’07

We, together with the other members of Century Bancorp, Inc. and 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, 2007. 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, 2007, 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 39.

A   W O R D   F R O M   O U R   C H A I R M A N

As a family-run business, the values that define our company are not 
just part of our company culture. They are the principles that guide 
our decisions and help us position our company for sustained growth.
Our prudent approach and long-term view proved to be the right
course in 2007 as we steered clear of the pitfalls faced by so many
other financial institutions.  

Marshall M. Sloane

The last major credit crisis I witnessed was in the early nineties, over 15 years ago. Century 
weathered that storm, while watching scores of peer institutions fail or be compelled to merge.
The current credit crisis is again predicated on real estate, but in a different securitized structure.
Regardless of the mechanics, we believed then, and we believe now, that banks will lose money
when they make the mistake of decentralized credit authority and allow unsupervised geographic
lending expansion.  

While our loan policies and choice to remain focused within our market area may have appeared
overly conservative several years ago, our decisions have served us well. We chose not to get 
involved in an overheated market of inflated appraisals and aggressive brokers. We have always
tightly controlled loan authorities and customer geography because we believe there is no 
substitute for local market knowledge. Our risk management philosophy has worked for us since
our inception, and it is one of the reasons we have consistently paid a dividend on our stock 
for the last 34 years.

By staying true to our 
own family’s values, we continue to 
build our franchise value.  

I watch with amazement as the “giants” of our industry replenish their depleted capital, following
the sub-prime charge-offs, with huge foreign equity infusions. Little is said about the dramatic 
dilution of value for existing shareholders in those recapitalizations. We have always been sensitive
to maintaining and creating value for our loyal long-term shareholders. This latest crisis is 
one more example of how being guided by our values and our independent thinking has proven 
to be in our shareholders’ best interests. Our shareholders are always foremost in our thoughts 
and plans.

As we approach our 40th anniversary, I am confident that Century’s strategy will 
hold true for the future.

Sincerely,

Marshall M. Sloane
Founder and Chairman
