2016 ANNUAL REPORT 
 
 
 
 
 
to our shareholders

Fellow Shareholders,

Solid Growth—By the Numbers

One of our greatest responsibilities is to ensure that  
NBT Bancorp Inc. (NBT) remains fundamentally strong from  
the inside out. That means focusing not only on the things  
we do as a company, but also on why and how we do them.

As a community bank, we rely on our local teams to develop 
new customer relationships and expand existing ones. By 
all accounts, they are getting the job done. Organic growth 
continued to be a key driver of NBT’s success:

We have long believed that when we live by our corporate 
values, we create a culture capable of sustaining consistently 
outstanding performance. On this point, NBT’s track record offers 
proof positive: For the fourth year in a row, the company set a 
new earnings record, generating net income of $78.4 million in 
2016, up from $76.4 million in 2015. Earnings per diluted share 
were $1.80 for 2016, up 5% from $1.72 the prior year.

Taking a longer look back, NBT has posted net income exceeding 
$50 million annually for more than a decade—a period that 
included many challenges for the financial services industry, 
such as the Great Recession. This equates to an annual return 
on average assets of over 90 basis points for all but one of those 
years: 2013 when we acquired Alliance Financial Corporation 
and finished at 85 basis points. What’s more, we achieved this 
profitability while investing in the expansion of our footprint  
into New England and completing the Alliance acquisition— 
the largest in our history.

•  Average demand deposits increased by 10% over 2015,  
the seventh consecutive year this growth has been 10%  
or higher.

•  Loans grew by 5.4% in 2016, compared to 5.1% in 2015.

•  2016 net interest income was up $11.8 million, or 4.7%, 
compared to 2015. This was driven by a $510.5 million 
increase in earning assets.

•  2016 noninterest income grew by $6 million, or 5%, 

compared to 2015 (excluding net securities gains and 
the gain on sale of an equity investment). Retirement 
plan income was up $2 million, while ATM and debit card 
income increased $1 million.

We also depend on our employees at all levels to find ways we 
can be more efficient, whether through streamlined processes 
or better use of resources. Again, their efforts paid off in 2016 
as improved operating efficiencies resulted in flat noninterest 
expense year over year.

We have no doubt that the commitment and capabilities of 
our employees are at the heart of this success, making what 
motivates and guides them of great importance. That’s why our 
management team gathered in 2016 to refine and reaffirm the 
values that form the foundation for most everything we do.

These values, combined with our vision, promote an 
environment where we can be innovative in pursuing new 
business opportunities and in responding to shifts in our markets 
and industry. They define everyday interactions with customers 
and colleagues. Ultimately, they inspire us to act in the best 
interests of the company, our customers and our shareholders.

Our shared values and strategic focus areas also help create 
continuity. This was on full display as management of the 
company transitioned seamlessly during 2016.

NBT BANCORP STOCK PRICE

We have always had confidence in our strong fundamentals, 
including growth in loan production, core deposit levels and 
fee income generation. We believed that investors who took 
the long view with respect to the potential of their investment 
would see it grow in value when the outlook for interest rates 
and the 
financial 
sector turned 
in a favorable 
direction. Last 
year that time 
arrived: NBT’s 
stock price 
increased by 
50% from

to year-end 
2016.

NBT BANCORPThe Road Ahead

Closing Thoughts

We will continue to focus on organic growth, which generates 
low-cost core deposits and reduces the company’s need 
to borrow. In 2016 alone, average demand deposit 
growth saved NBT approximately $4.5 million in 
interest expense.

Our New England expansion states of Vermont, 
Massachusetts, New Hampshire and Maine will 
continue to be an important part of that organic 
growth. We maintained our positive trajectory in  
New England in 2016 with total loans outstanding exceeding 
$1 billion, an increase of more than 24% over the prior year.

We expect that noninterest income, particularly from our Wealth 
Management business, will continue to gain momentum as 
a significant contributor to the bottom line. Two acquisitions 
completed in 2016 added new capabilities that complement our 
established wealth management services: Actuarial Designs & 
Solutions, Inc. is a retirement plan consulting and services firm, 
and Columbia Ridge Capital Management, Inc. is a registered 
investment advisor. 

NBT has always taken pride in employing technology to better 
serve our customers. Our digital capacity is constantly evolving 
to address the needs of increasingly mobile customers. We 
offer them more tools than ever to manage their finances from 
anywhere, at any time, through virtually any device connected  
to the Internet.

We continue to extend our digital branch model, recently 
completing work on our fourth such location in Hamilton, N.Y. 
These branches offer advanced self-service technology and 
layouts that facilitate a side-by-side customer/banker experience. 
Other digital initiatives include the more robust delivery of 
marketing messages through targeted, measurable channels 
and the introduction of interactive resources to help our 
employees sell, collaborate and grow professionally.

We see last year as the continuation of a remarkable story,  

one that now dates back 160 years! NBT ended 2016 with 
$8.9 billion in assets, up 7.3% from the close of 2015.  

160

YEARS
NBT BANK
HISTORY

SNL Financial ranked NBT the 84th largest bank in the 
U.S. based on total assets as of December 31, 2016. 
We are that much closer to crossing the threshold 
of $10 billion in assets and are on track with our 
readiness plan to meet the regulatory compliance 

requirements associated with that milestone.

Reflecting its continued confidence in the company’s financial 
health, the Board of Directors voted to pay out a 500th 
consecutive cash dividend in March 2017—another record  
we are very proud of.

For the last decade, the banking industry has grappled with a 
sluggish economy, historically low interest rates and significant 
new government regulation. Recently, the Federal Reserve 
has signaled the likelihood of multiple increases in the Federal 
Funds Rate in 2017. Moreover, momentum appears to have 
shifted toward viable and reasonable regulatory reform, as well 
as corporate tax relief. While we support sensible reforms, we 
are also keenly aware of the need to preserve the safety and 
soundness of our nation’s financial system. We look forward  
to more clarity on these matters in the near future.

We believe NBT is well positioned for continued solid 
performance based on our strong fundamentals, outstanding 
team, investments in technology and aligned culture. We know 
that our values and strategies have produced enviable results 
through some challenging times, and we expect even greater 
success as conditions improve for our industry.

We would like to thank our directors, shareholders, employees 
and our 500,000 customers for all of your enthusiastic support.

2016 ANNUAL REPORT 
seamless 
transitions

NBT executives rang  

the Nasdaq opening bell  

on December 19, 2016,  

celebrating 160 years in business 

for NBT Bank and a transition to 

new leadership for the company.

When Daryl R. Forsythe was named president and chief 
executive officer of NBT Bancorp and NBT Bank in 1995,  
Martin A. Dietrich had been with NBT for 14 years, working  
in various management capacities. Suffice it to say, they  
would come to know each other pretty well and forge a strong 
relationship in the years that followed. This set the table for over 
two decades of stable, like-minded leadership, as Marty would 
eventually succeed Daryl as CEO in 2006 and serve through 2016.

This past year will be remembered for some historic and 
seamless transitions in the company’s corporate governance.  
In May 2016, Daryl retired from his role as NBT’s chairman, 
bringing to a close 28 years of service to the company.

At the same time, the Board of Directors elected Marty chairman 
and announced a succession plan, promoting John H. Watt, Jr. 
to the position of NBT Bank president and naming him Marty’s 
successor as CEO of the holding company and bank at the end 
of 2016, when Marty retired from those posts.

John joined NBT in 2014 and has played a key leadership role 
in several areas: commercial and consumer lending, credit 
administration and marketing. He was previously executive vice 

president for commercial banking, investment management 
and bank operations and a director with Alliance Financial 
Corporation, which was acquired by NBT in 2013.

On December 19, 2016, NBT had the honor of ringing the  
bell to open the Nasdaq Stock Market for the second time  
in the company’s history, commemorating the bank’s 160th 
anniversary and the official transition of the CEO role from  
Marty to John.

Also in 2016, the board structure was streamlined so that the 
same directors serve on both the holding company and bank 
boards. The Board believes this evolution in the company’s 
corporate structure represents a step toward more continuity, 
efficiency and agility.

The Board and the Executive Management Team would like to 
extend many thanks to Brian K. Hanaburgh, Susan H. Kwiatek, 
Thomas G. Mazzotta and Russell B. Strait, who completed  
terms of service on the bank board last May. In addition,  
they recognize V. Daniel Robinson, II, Matthew J. Salanger  
and Andrew S. Kowalczyk, III, as they began terms of  
service on the holding company board in December.

PART I

ITEM 1.  BUSINESS

NBT  Bancorp  Inc.  (the “Registrant”  or  the “Company”)  is  a
registered financial holding company incorporated in the state
of Delaware in 1986, with its principal headquarters located in
Norwich, New York. The Company, on a consolidated basis, at
December 31, 2016 had assets of $8.9 billion and stockholders’
equity of $913.3 million.

The  principal  assets  of  the  Registrant  consist  of  all  of  the
outstanding shares of common stock of its subsidiaries, includ-
ing: NBT Bank, National Association (the “Bank”), NBT Financial
Services, Inc. (“NBT Financial”), NBT Holdings, Inc. (“NBT Hold-
ings”), Hathaway Agency, Inc., CNBF Capital Trust I, NBT Statutory
Trust I, NBT Statutory Trust II, Alliance Financial Capital Trust I,
and Alliance Financial Capital Trust II (collectively, the “Trusts”).
The Company’s principal sources of revenue are the manage-
ment fees and dividends it receives from the Bank, NBT Financial
and NBT Holdings.

The Company’s business, primarily conducted through the
Bank but also through its other subsidiaries, consists of providing
commercial banking and financial services primarily to customers
in its market area, which includes central and upstate New York,
northeastern Pennsylvania, southern New Hampshire, western
Massachusetts, Vermont, and the greater Portland, Maine area.
The Company has been, and intends to continue to be, a com-
munity-oriented financial institution offering a variety of financial
services. The Company’s business philosophy is to operate as a
community bank with local decision-making, principally in non-
metropolitan markets, providing a broad array of banking and
financial services to retail, commercial, and municipal customers.
The financial condition and operating results of the Company
are dependent on its net interest income which is the difference
between the interest and dividend income earned on its earning
assets, primarily loans and investments, and the interest expense
paid on its interest bearing liabilities, primarily consisting of
deposits and borrowings. Among other factors, net income is
also affected by provisions for loan losses and noninterest income,
such as service charges on deposit accounts, insurance and other
financial services fees, trust revenue, and gains/losses on securities
sales, bank owned life insurance income, ATM and debit card
fees, and retirement plan administration fees as well as noninterest
expense, such as salaries and employee benefits, occupancy,
equipment, data processing and communications, professional
fees and outside services, office supplies and postage, amorti-
zation, loan collection and other real estate owned (“OREO”)
expenses, advertising, FDIC expenses, and other expenses.

Like much of the nation, some of the market areas that the
Company  serves  are  still  experiencing  economic  challenges
and volatility. A variety of factors (e.g., any substantial rise in
inflation or rise in unemployment rates, decrease in consumer
confidence, adverse international economic conditions, natural
disasters, war, or political instability) may affect both the Com-
pany’s  markets  and  the  national  market. The  Company  will
continue to emphasize managing its funding costs and lending
and  investment  rates  to  effectively  maintain  profitability.  In
addition, the Company will continue to seek and maintain rela-
tionships that can generate noninterest income. We anticipate
that this approach should help mitigate profit fluctuations that
are caused by movements in interest rates, business and con-
sumer loan cycles, and local economic factors.

NBT Bank, N.A.

The Bank is a full service commercial bank formed in 1856,
which  provides  a  broad  range  of  financial  products  to  indi-
viduals, corporations and municipalities throughout the central

Massachusetts,  southern  New  Hampshire, Vermont,  and  the
greater Portland, Maine market areas.

Through its network of branch locations, the Bank offers a
wide range of products and services tailored to individuals, busi-
nesses, and municipalities. Deposit products offered by the Bank
include demand deposit accounts, savings accounts, negotiable
order of withdrawal (“NOW”) accounts, money market deposit
accounts (“MMDA”), and certificate of deposit (“CD”) accounts.
The Bank offers various types of each deposit account to accom-
modate the needs of its customers with varying rates, terms,
and features. Loan products offered by the Bank include consumer
loans, home equity loans, mortgages, business banking loans
and commercial loans, with varying rates, terms and features to
accommodate the needs of its customers. The Bank also offers
various other products and services through its branch network

uct and service information. The Bank provides 24-hour access

The Trusts

The Trusts  were  organized  to  raise  additional  regulatory
capital and to provide funding for certain acquisitions. CNBF
Capital Trust I (“Trust I”) and NBT Statutory Trust I are Delaware
statutory business trusts formed in 1999 and 2005, respectively,
for the purpose of issuing trust preferred securities and lending
the proceeds to the Company. In connection with the acquisition
of CNB Bancorp, Inc., the Company formed NBT Statutory Trust
II (“Trust II”) in February 2006 to fund the cash portion of the
acquisition as well as to provide regulatory capital. In connec-
tion  with  the  acquisition  of  Alliance  Financial  Corporation
(“Alliance”), the Company acquired two statutory trusts, Alliance
Financial Capital Trust I and Alliance Financial Capital Trust II,
which were formed in 2003 and 2006, respectively. The Company
guarantees,  on  a  limited  basis,  payments  of  distributions  on
the trust preferred securities and payments on redemption of
the  trust  preferred  securities. The Trusts  are  variable  interest
entities for which the Company is not the primary beneficiary,
as defined by Financial Accounting Standards Board (“FASB”)
Accounting Standards Codification (“ASC”). In accordance with
ASC, the accounts of the Trusts are not included in the Com-
pany’s consolidated financial statements.

Operating Subsidiaries of the Bank

The Bank has seven operating subsidiaries, NBT Capital Corp.,
Broad Street Property Associates, Inc., NBT Services, Inc., CNB

Alliance Leasing, Inc. was formed in 2002 to provide equipment
leasing services. Columbia Ridge Capital Management, Inc. was
acquired in 2016 and is a registered investment advisor that
provides investment advice and financial consulting services.

Competition

The financial services industry, including commercial banking,
is highly competitive, and we encounter strong competition
for deposits, loans and other financial products and services
in our market area. The increasingly competitive environment
is the result of the continued low rate environment, changes
in regulation, changes in technology and product delivery sys-
tems, additional financial service providers, and the accelerating
pace of consolidation among financial services providers. The
Company  competes  for  loans,  deposits,  and  customers  with
other commercial banks, savings and loan associations, securities
and  brokerage  companies,  mortgage  companies,  insurance
companies,  finance  companies,  money  market  funds,  credit
unions, and other nonbank financial service providers.

The  financial  services  industry  could  become  even  more
competitive as a result of legislative, regulatory and technological
changes and continued consolidation. Banks, securities firms
and insurance companies can merge under the umbrella of a
financial holding company, which can offer virtually any type
of financial service, including banking, securities underwriting,
insurance (both agency and underwriting) and merchant bank-
ing. Also, technology has lowered barriers to entry and made
it possible for non-banks to offer products and services tradi-
tionally  provided  by  banks,  such  as  automatic  transfer  and
automatic payment systems.

Some of the Company’s nonbanking competitors have fewer
regulatory constraints and may have lower cost structures. In
addition, some of the Company’s competitors have assets, capital
and  lending  limits  greater  than  that  of  the  Company,  have
greater access to capital markets and offer a broader range of
products  and  services  than  the  Company. These  institutions
may have the ability to finance wide-ranging advertising cam-
paigns and may also be able to offer lower rates on loans and
higher rates on deposits than the Company can offer. Some of
these institutions offer services, such as credit cards and inter-
national banking, which the Company does not directly offer.

Various in-state market competitors and out-of-state banks
continue to enter or have announced plans to enter or expand
their presence in the market areas in which the Company cur-
rently operates. With the addition of new banking presences
within our market, the Company expects increased competition
for loans, deposits, and other financial products and services.
In order to compete with other financial services providers,
the  Company  stresses  the  community  nature  of  its  banking
operations and principally relies upon local promotional activ-
ities, personal relationships established by officers, directors,
and employees with their customers, and specialized services
tailored to meet the needs of the communities served. We also

offer  certain  customer  services,  such  as  agricultural  lending,
that  many  of  our  larger  competitors  do  not  offer. While  the
Company’s position varies by market, the Company’s manage-
ment believes that it can compete effectively as a result of local
market  knowledge,  local  decision  making,  and  awareness  of
customer needs.

The table below summarizes the Bank’s deposits and market
share by the thirty-eight counties of New York, Pennsylvania,
New Hampshire, Massachusetts, Vermont, and Maine in which
it had customer facilities as of June 30, 2016. Market share is
based on deposits of all commercial banks, credit unions, sav-

Supervision and Regulation

The Company, the Bank and certain of its non-banking sub-
sidiaries are subject to extensive regulation under federal and
state laws. The regulatory framework applicable to bank holding
companies and their subsidiary banks is intended to protect
depositors, federal deposit insurance funds, and the stability
of  the  U.S.  banking  system. This  system  is  not  designed  to
protect equity investors in bank holding companies, such as
the Company.

Set  forth  below  is  a  summary  of  the  significant  laws  and
regulations  applicable  to  the  Company  and  its  subsidiaries.
The description that follows is qualified in its entirety by refer-
ence to the full text of the statutes, regulations, and policies
that are described. Such statutes, regulations, and policies are
subject to ongoing review by Congress and state legislatures
and federal and state regulatory agencies. A change in any of
the  statutes,  regulations,  or  regulatory  policies  applicable  to
the Company and its subsidiaries could have a material effect
on the results of the Company.

Overview

The  Company  is  a  registered  bank  holding  company  and
financial holding company under the Bank Holding Company
Act of 1956, as amended (the “BHC Act”), and is subject to the
supervision of and regular examination by the Board of Gov-
ernors  of  the  Federal  Reserve  System  (the “Federal  Reserve
Board” or “FRB”) as its primary federal regulator. The Company
is also subject to the jurisdiction of the Securities and Exchange
Commission (“SEC”) and is subject to the disclosure and other
regulatory  requirements  of  the  Securities  Act  of  1933,  as
amended, and the Securities Exchange Act of 1934, as amended,
as administered by the SEC. The Company’s common stock is
listed on the NASDAQ Global Select market under the ticker
symbol, “NBTB,” and the Company is subject to the NASDAQ
stock market rules.

The  Bank  is  chartered  as  a  national  banking  association
under the National Bank Act. The Bank is subject to the super-
vision of, and to regular examination by, the Office of the Comp-
troller of the Currency (“OCC”) as its chartering authority and
primary federal regulator. The Bank is also subject to the super-
vision and regulation, to a limited extent, of the Federal Deposit
Insurance Corporation (“FDIC”) as its deposit insurer. Financial
products and services offered by the Company and the Bank
are  subject  to  federal  consumer  protection  laws  and  imple-
menting regulations promulgated by the Consumer Financial
Protection  Bureau  (“CFPB”). The  Company  and  the  Bank  are
also subject to oversight by state attorneys general for com-
pliance with state consumer protection laws. The Bank’s deposits

are insured by the FDIC up to the applicable deposit insurance
limits in accordance with FDIC laws and regulations. The non-
bank subsidiaries of the Company and the Bank are subject to
federal and state laws and regulations, including regulations
of the FRB and the OCC, respectively.

The Dodd-Frank Wall Street Reform and Consumer Protection
Act of 2010 (the “Dodd-Frank Act”) has significantly changed
the financial regulatory landscape in the U.S. Several provisions
of the Dodd-Frank Act are subject to further rulemaking, guid-
ance and interpretation by the federal banking agencies. Con-
sidering the recent changes in administration and controlling
party in the U.S., Congress, state legislatures and financial reg-
ulatory agencies may introduce various legislative and regulatory
initiatives that are likely to impact the financial services industry,
generally. However, it is not clear whether such changes will
be introduced at all or will be implemented successfully. As a
result, management cannot predict the ultimate impact of the
Dodd-Frank Act or potential additional reforms in the regulation
of financial institutions, or the extent to which they could affect
operations of the Company and the Bank.

Federal Bank Holding Company Regulation

The Company is a bank holding company as defined by the
BHC Act. The BHC Act generally limits the business of the Com-
pany  to  banking,  managing  or  controlling  banks,  and  other
activities that the FRB has determined to be so closely related
to banking “as to be a proper incident thereto.” The Company
has also qualified for and elected to be a financial holding com-
pany. Financial holding companies may engage in any activity,
or acquire and retain the shares of a company engaged in any
activity that is either (i) financial in nature or incidental to such
financial  activity  (as  determined  by  the  FRB  in  consultation
with the Secretary of the Treasury), or (ii) complementary to a
financial activity, and that does not pose a substantial risk to
the safety and soundness of depository institutions or the finan-
cial system (as solely determined by the FRB). If a bank holding
company  seeks  to  engage  in  the  broader  range  of  activities
permitted under the BHC Act for financial holding companies,
(i) the bank holding company and all of its depository institution
subsidiaries must be “well-capitalized” and “well-managed,” as
defined in the FRB’s Regulation Y, and (ii) it must file a declaration
with the FRB that it elects to be a “financial holding company.”
In  order  for  a  financial  holding  company  to  commence  any
activity that is financial in nature, incidental thereto, or com-
plementary  to  a  financial  activity,  or  to  acquire  a  company
engaged in any such activity permitted by the BHC Act, each
insured depository institution subsidiary of the financial holding
company must have received a rating of at least “satisfactory”

in its most recent examination under the Community Reinvest-
ment Act of 1977 (the “CRA”). See the section titled “Community
Reinvestment Act of 1977” for further information relating to
the CRA.

Regulation of Mergers and Acquisitions

The BHC Act, the Bank Merger Act, and other federal and
state statutes regulate acquisitions of depository institutions
and their holding companies. The BHC Act requires prior FRB
approval  for  a  bank  holding  company  to  acquire,  directly  or
indirectly, 5% or more of any class of voting securities of a com-
mercial bank or its parent holding company and for a company,
other than a bank holding company, to acquire 25% or more
of any class of voting securities of a bank or bank holding com-
pany. Under the Change in Bank Control Act, any person, includ-
ing a company, may not acquire, directly or indirectly, control
of a bank without providing 60 days’ prior notice and receiving
a non-objection from the appropriate federal banking agency.
Under  the  Bank  Merger  Act,  prior  approval  of  the  OCC  is
required for a national bank to merge with another bank where
the  national  bank  is  the  surviving  bank  or  to  purchase  the
assets or assume the deposits of another bank. In reviewing
applications seeking approval of merger and acquisition trans-
actions,  the  federal  banking  agencies  will  consider,  among
other criteria, the competitive effect and public benefits of the
transactions,  the  capital  position  of  the  combined  banking
organization,  the  applicant’s  performance  record  under  the
CRA, and the effectiveness of the subject organizations in com-
bating money laundering activities.

As a financial holding company, the Company is permitted
to acquire control of non-depository institutions engaged in
activities that are financial in nature and in activities that are
incidental and complementary to financial activities without
prior FRB approval. However, the BHC Act, as amended by the
Dodd-Frank Act, requires prior written approval from the FRB
or  prior  written  notice  to  the  FRB  before  a  financial  holding
company may acquire control of a company with consolidated
assets of $10 billion or more.

Capital Distributions

The principal source of the Company’s liquidity is dividends
from  the  Bank. The  OCC  oversees  the  ability  of  the  Bank  to
make capital distributions, including dividends. The OCC gen-
erally prohibits a depository institution from making any capital
distributions (including payment of a dividend) or paying any
management  fee  to  its  parent  holding  company  if  the  bank
would thereafter be undercapitalized. The OCC’s prior approval
is required if the total of all dividends declared by a national
bank in any calendar year would exceed the sum of the bank’s

net income for that year and its undistributed net income for
the preceding two calendar years, less any required transfers
to surplus. The National Bank Act also prohibits national banks
from paying dividends that would be greater than the bank’s
undivided profits after deducting statutory bad debt in excess
of the bank’s allowance for loan losses.

The  federal  banking  agencies  have  indicated  that  paying
dividends that deplete a bank’s capital base to an inadequate
level would be an unsafe and unsound banking practice and
that  banking  organizations  should  generally  pay  dividends
only out of current operating earnings. The appropriate federal
regulatory authority is authorized to determine, based on the
financial condition of a bank holding company or a bank, that
the  payment  of  dividends  would  be  an  unsafe  or  unsound
practice and to prohibit such payment.

Affiliate and Insider Transactions

Transactions between the Bank and its affiliates, including
the  Company,  are  governed  by  sections  23A  and  23B  of  the
Federal  Reserve  Act  (the “FRA”)  and  the  FRB’s  implementing
Regulation W. An “affiliate” of a bank includes any company or
entity that controls, is controlled by, or is under common control
with the Bank. In a bank holding company context, at a mini-
mum, the parent holding company of a bank, and any compa-
nies  which  are  controlled  by  such  parent  holding  company,
are affiliates of the bank. Generally, sections 23A and 23B of
the FRA are intended to protect insured depository institutions
from losses in transactions with affiliates. These sections place
quantitative and qualitative limitations on covered transactions
between the Bank and its affiliates, and require that all trans-
actions between a bank and its affiliates occur on market terms
that are consistent with safe and sound banking practices.

Section 22(h) of the FRA and its implementing Regulation
O restricts loans to directors, executive officers, and principal
stockholders (“Insiders”). Under Section 22(h), loans to Insiders
and their related interests may not exceed, together with all
other outstanding loans to such persons and affiliated entities,
the  institution’s  total  capital  and  surplus.  Loans  to  Insiders
above  specified  amounts  must  receive  the  prior  approval  of
the Bank’s board of directors. Further, under Section 22(h) of
the  FRA,  loans  to  directors,  executive  officers,  and  principal
stockholders must be made on terms substantially the same
as offered in comparable transactions to other persons, except
that such insiders may receive preferential loans made under
a benefit or compensation program that is widely available to
the  Bank’s  employees  and  does  not  give  preference  to  the
insider  over  the  employees.  Section  22(g)  of  the  FRA  places
additional limitations on loans to executive officers.

Federal Deposit Insurance and Brokered Deposits

The FDIC’s deposit insurance limit is $250,000 per depositor,
per  insured  bank,  for  each  account  ownership  category. The
Bank’s deposit accounts are fully insured by the FDIC Deposit
Insurance Fund (the “DIF”) up to the deposit insurance limits
in accordance with applicable laws and regulations.

The FDIC uses a risk-based assessment system that imposes
insurance premiums based upon a risk matrix that takes into
account a bank’s capital level and supervisory rating (“CAMELS
rating”). The  risk  matrix  uses  different  risk  categories  distin-
guished by capital levels and supervisory ratings. As a result
of the Dodd-Frank Act, the base for deposit insurance assess-
ments is now consolidated average assets less average tan-
gible equity. Assessment rates are calculated using formulas
that take into account the risk of the institution being assessed.
In  addition  to  deposit  insurance  assessments,  the  Federal
Deposit Insurance Act (“FDIA”) provides for additional assess-
ments  to  be  imposed  on  insured  depository  institutions  to
pay for the cost of Financing Corporation funding. Financing
Corporation  is  a  mixed-ownership  government  corporation
established by the Competitive Equality Banking Act of 1987
whose sole purpose was to function as a financing vehicle for
the now defunct Federal Savings & Loan Insurance Company.
The Financing Corporation assessments are adjusted quarterly
to reflect changes in the assessment base of the DIF and do
not vary depending upon a depository institution’s capitaliza-
tion or supervisory evaluation.

Under FDIC laws and regulations, no FDIC-insured depository
institution can accept brokered deposits unless it is well-cap-
italized, or unless it is adequately capitalized and receives a
waiver  from  the  FDIC.  Applicable  laws  and  regulations  also
prohibit any depository institution that is not well-capitalized
from paying an interest rate on brokered deposits in excess
of  three-quarters  of  one  percentage  point  over  certain  pre-
vailing market rates.

The Dodd-Frank Act requires that the FDIC raise the mini-
mum reserve ratio of the DIF from 1.15 percent to 1.35 percent,
and that the FDIC offset the effect of this increase on insured
depository institutions with total consolidated assets of less
than  $10  billion.  In  March  2016,  the  FDIC  issued  a  final  rule
affecting insured depository institutions with total consolidated
assets of more than $10 billion. The final rule imposes a sur-
charge  of  4.5  cents  per  $100  of  the  institution’s  assessment
base  on  deposit  insurance  assessment  rates  paid  by  these
larger  institutions.  If  the  reserve  ratio  does  not  reach  1.35%
by  December  31,  2018,  through  implementation  of  the  sur-
charge, the FDIC will impose an additional, one-time shortfall
assessment on insured depository institutions with more than

$10 billion in assets on March 31, 2019, to be paid by June 30,
2019. The FDIC also has authority to further increase deposit
insurance  assessments.  At  this  time,  the  Bank  is  not  subject
to this surcharge.

Under the FDIA, the FDIC may terminate deposit insurance
upon a finding that the institution has engaged in unsafe and
unsound  practices,  is  in  an  unsafe  or  unsound  condition  to
continue operations, or has violated any applicable law, regu-
lation, rule, order or condition imposed by the FDIC. The Bank’s
management is not aware of any practice, condition, or violation
that might lead to the termination of its deposit insurance.

Federal Home Loan Bank System

The Bank is also a member of the Federal Home Loan Bank
(“FHLB”)  of  New York,  which  provides  a  central  credit  facility
primarily  for  member  institutions  for  home  mortgage  and
neighborhood  lending. The  Bank  is  subject  to  the  rules  and
requirements of the FHLB, including the requirement to acquire
and hold shares of capital stock in the FHLB in an amount at
least  equal  to  the  sum  of  0.35%  of  the  aggregate  principal
amount of its unpaid residential mortgage loans and similar
obligations at the beginning of each year, up to a maximum
of $25.0 million. The Bank was in compliance with FHLB rules
and requirements as of December 31, 2016.

Debit Card Interchange Fees

The Dodd-Frank Act requires that any interchange transaction
fee charged for a debit transaction be reasonable and propor-
tional  to  the  cost  incurred  by  the  issuer  for  the  transaction.
FRB regulations mandated by the Dodd-Frank Act limit inter-
change fees on debit cards to a maximum of 21 cents per trans-
action plus 5 basis points of the transaction amount. The rule
also permits a fraud-prevention adjustment of 1 cent per trans-
action conditioned upon an issuer developing, implementing,
and updating reasonably designed fraud-prevention policies
and procedures. Issuers that, together with their affiliates, have
less than $10 billion of assets, such as the Company, are exempt
from the debit card interchange fee standards. However, FRB
regulations prohibit all issuers, including the Company and the
Bank, from restricting the number of networks over which elec-
tronic  debit  transactions  may  be  processed  to  less  than  two
unaffiliated networks.

Source of Strength Doctrine

FRB  policy  requires  bank  holding  companies  to  act  as  a
source of financial and managerial strength to their subsidiary
banks. Section 616 of the Dodd-Frank Act codifies the require-
ment that bank holding companies serve as a source of financial

NBT BANCORP 2016 FORM 10-K

9

strength to their subsidiary depository institutions. As a result,
the Company is expected to commit resources to support the
Bank, including at times when the Company may not be in a
financial position to provide such resources. Any capital loan
by the Company to the Bank is subordinate in right of payment
to deposits and to certain other indebtedness of such subsidiary
banks. The U.S. Bankruptcy Code provides that, in the event of
a  bank  holding  company’s  bankruptcy,  any  commitment  by
the bank holding company to a federal bank regulatory agency
to maintain the capital of a subsidiary bank will be assumed
by the bankruptcy trustee and entitled to priority of payment.
In addition, under the National Bank Act, if the Bank’s capital
stock is impaired by losses or otherwise, the OCC is authorized
to require payment of the deficiency by assessment upon the
Company. If the assessment is not paid within three months,
the OCC could order a sale of Bank stock held by the Company
to cover any deficiency.

Capital Adequacy and Prompt Corrective Action

In July 2013, the FRB, the OCC and the FDIC approved final
rules (the “Capital Rules”) that established a new capital frame-
work for U.S. banking organizations. The Capital Rules generally
implement the Basel Committee on Banking Supervision’s (the
“Basel  Committee”)  December  2010  final  capital  framework
referred to as “Basel III” for strengthening international capital
standards. The Capital Rules revise the definitions and the com-
ponents of regulatory capital, as well as address other issues
affecting  the  numerator  in  banking  institutions’  regulatory
capital ratios. The Capital Rules also address asset risk weights
and other matters affecting the denominator in banking insti-
tutions’ regulatory capital ratios and replace the existing general
risk-weighting approach with a more risk-sensitive approach.
The Capital Rules: (i) require a capital measure called “Com-
mon Equity Tier 1” (“CET1”) and related regulatory capital ratio
of CET1 to risk-weighted assets; (ii) specify that Tier 1 capital
consists  of  CET1  and “Additional Tier  1  capital”  instruments
meeting certain revised requirements; (iii) mandate that most
deductions/adjustments  to  regulatory  capital  measures  be
made to CET1 and not to the other components of capital; and
(iv) expand the scope of the deductions from and adjustments
to capital as compared to existing regulations. Under the Capital
Rules, for most banking organizations, including the Company,
the  most  common  form  of  Additional Tier  1  capital  is  non-
cumulative perpetual preferred stock and the most common
forms of Tier 2 capital are subordinated notes and a portion of
the allocation for loan losses, in each case, subject to the Capital
Rules’ specific requirements.

Pursuant to the Capital Rules, the minimum capital ratios

as of January 1, 2015 are:

•  4.5% CET1 to risk-weighted assets;

•  6.0% Tier 1 capital (CET1 plus Additional Tier 1 capital) to

risk-weighted assets;

•  8.0% Total capital (Tier 1 capital plus Tier 2 capital) to risk-

weighted assets; and

•  4.0% Tier  1  capital  to  average  consolidated  assets  as
reported on consolidated financial statements (known as
the “leverage ratio”).

The Capital Rules also require a “capital conservation buffer,”
composed  entirely  of  CET1,  on  top  of  these  minimum  risk-
weighted asset ratios. The capital conservation buffer is designed
to absorb losses during periods of economic stress. Banking
institutions with a ratio of CET1 to risk-weighted assets above
the  minimum  but  below  the  capital  conservation  buffer  will
face constraints on dividends, equity and other capital instru-
ment repurchases and compensation based on the amount of
the  shortfall. When  fully  phased-in  on  January  1,  2019,  the
capital standards applicable to the Company and the Bank will
include  an  additional  capital  conservation  buffer  of  2.5%  of
CET1, effectively resulting in minimum ratios inclusive of the
capital conservation buffer of (i) CET1 to risk-weighted assets
of  at  least  7%,  (ii) Tier  1  capital  to  risk-weighted  assets  of  at
least 8.5%, and (iii) Total capital to risk-weighted assets of at
least 10.5%. The risk-weighting categories in the Capital Rules
are standardized and include a risk-sensitive number of cate-
gories, depending on the nature of the assets, generally ranging
from 0% for U.S. government and agency securities, to 600%
for certain equity exposures, and resulting in higher risk weights
for a variety of asset classes.

The Capital Rules provide for a number of deductions from
and  adjustments  to  CET1. These  include,  for  example,  the
requirement that mortgage servicing rights, deferred tax assets
arising from temporary differences that could not be realized
through net operating loss carrybacks and significant invest-
ments in non-consolidated financial entities be deducted from
CET1 to the extent that any one such category exceeds 10%
of CET1 or all such items, in the aggregate, exceed 15% of CET1.
The deductions and adjustments will be incrementally phased
in between January 1, 2015 and January 1, 2019.

In addition, under the prior general risk-based capital rules,
the  effects  of  accumulated  other  comprehensive  income  or
loss (“AOCI”) items included in stockholders’ equity (for example,
marks-to-market  of  securities  held  in  the  available-for-sale
portfolio)  under  GAAP  were  excluded  for  the  purposes  of

10

NBT BANCORP 2016 FORM 10-K

determining regulatory capital ratios. Under the Capital Rules,
the effects of certain AOCI items are not excluded; however,
banking  organizations  not  using  the  advanced  approaches,
including the Company, and the Bank, were permitted to make
a one-time permanent election to continue to exclude these
items in January 2015. The Capital Rules also preclude certain
hybrid  securities,  such  as  trust  preferred  securities  issued
after May 19, 2010, from inclusion in bank holding companies’
Tier 1 capital.

Implementation of the deductions and other adjustments
to CET1 began on January 1, 2015, are phased-in over a 4-year
period (beginning at 40% on January 1, 2015 and an additional
20%  per  year  thereafter). The  implementation  of  the  capital
conservation buffer began on January 1, 2016 at the 0.625%
level and increase by 0.625% on each subsequent January 1,
until it reaches 2.5% on January 1, 2019.

Management believes that the Company is in compliance,
and will continue to be in compliance, with the targeted capital
ratios as such requirements are phased in.

Prompt Corrective Action and Safety and Soundness

Pursuant to Section 38 of the Federal Deposit Insurance Act
(“FDIA”), federal banking agencies are required to take “prompt
corrective action” (“PCA”) should an insured depository insti-
tutions fail to meet certain capital adequacy standards. At each
successive lower capital category, an insured depository insti-
tution is subject to more restrictions and prohibitions, including
restrictions  on  growth,  restrictions  on  interest  rates  paid  on
deposits, restrictions or prohibitions on payment of dividends
and restrictions on the acceptance of brokered deposits. Fur-
thermore,  if  an  insured  depository  institution  is  classified  in
one of the undercapitalized categories, it is required to submit
a capital restoration plan to the appropriate federal banking
agency,  and  the  holding  company  must  guarantee  the  per-
formance  of  that  plan.  Based  upon  its  capital  levels,  a  bank
that is classified as well-capitalized, adequately capitalized, or
undercapitalized may be treated as though it were in the next
lower capital category if the appropriate federal banking agency,
after notice and opportunity for hearing, determines that an
unsafe or unsound condition, or an unsafe or unsound practice,
warrants such treatment.

For purposes of PCA, to be: (i) well-capitalized, an insured
depository institution must have a total risk based capital ratio
of at least 10%, a Tier 1 risk based capital ratio of at least 8%,
a  CET1  risk  based  capital  ratio  of  at  least  6.5%,  and  a Tier  1
leverage  ratio  of  at  least  5%;  (ii)  adequately  capitalized,  an
insured  depository  institution  must  have  a  total  risk  based
capital ratio of at least 8%, a Tier 1 risk based capital ratio of

at  least  6%,  a  CET1  risk  based  capital  ratio  of  at  least  4.5%,
and a Tier 1 leverage ratio of at least 4%; (iii) undercapitalized,
an insured depository institution would have a total risk based
capital ratio of less than 8%, a Tier 1 risk based capital ratio of
less than 6%, a CET1 risk based capital ratio of less than 4.5%,
and  a Tier  1  leverage  ratio  of  less  than  4%;  (iv)  significantly
undercapitalized, an insured depository institution would have
a  total  risk  based  capital  ratio  of  less  than  6%,  a Tier  1  risk
based capital ratio of less than 4%, a CET1 risk based capital
ratio of less than 3%, and a Tier 1 leverage ratio of less than
3%.; (v) critically undercapitalized, an insured depository insti-
tution  would  have  a  ratio  of  tangible  equity  to  total  assets
that is less than or equal to 2%.

Bank holding companies and insured depository institutions
may also be subject to potential enforcement actions of varying
levels of severity for unsafe or unsound practices in conducting
their business, or for violation of any law, rule, regulation, con-
dition imposed in writing by the agency or term of a written
agreement with the agency. In more serious cases, enforcement
actions may include the issuance of directives to increase capital;
the issuance of formal and informal agreements; the imposition
of civil monetary penalties; the issuance of a cease and desist
order that can be judicially enforced; the issuance of removal
and  prohibition  orders  against  officers,  directors,  and  other
institution-affiliated  parties;  the  termination  of  the  insured
depository institution’s deposit insurance; the appointment of
a conservator or receiver for the insured depository institution;
and the enforcement of such actions through injunctions or
restraining  orders  based  upon  a  judicial  determination  that
the FDIC, as receiver, would be harmed if such equitable relief
was not granted.

Volcker Rule

Section 619 of the Dodd-Frank Act, commonly known as the
Volcker Rule, restricts the ability of banking entities, such as the
Company,  from:  (i)  engaging  in “proprietary  trading”  and  (ii)
investing in or sponsoring certain covered funds, subject to cer-
tain limited exceptions. Under the Volcker Rule, the term “covered
funds”  is  defined  as  any  issuer  that  would  be  an  investment
company under the Investment Company Act but for the exemp-
tions in section 3(c)(1) or 3(c)(7) of that Act, which includes col-
lateralized  loan  obligation  (“CLO”)  and  collateralized  debt
obligation securities. The regulation also provides an exemption
for CLOs meeting certain requirements. Compliance with the
Volcker Rule is generally required by July 21, 2017. Given the
Company’s  size  and  the  scope  of  its  activities,  the  Company
does not believe the implementation of the Volcker Rule will
have a significant effect on its consolidated financial statements.

Depositor Preference

The FDIA provides that, in the event of the “liquidation or
other resolution” of an insured depository institution, the claims
of depositors of the institution, including the claims of the FDIC
as subrogee of insured depositors, and certain claims for admin-
istrative expenses of the FDIC as a receiver, will have priority
over other general unsecured claims against the institution. If
an insured depository institution fails, insured and uninsured
depositors, along with the FDIC, will have priority in payment
ahead of unsecured, non-deposit creditors, including the parent
bank holding company, with respect to any extensions of credit
they have made to such insured depository institution.

Consumer Protection and CFPB Supervision

The Dodd-Frank Act centralized responsibility for consumer
financial  protection  by  creating  the  CFPB,  an  independent
agency charged with responsibility for implementing, enforcing,
and  examining  compliance  with  federal  consumer  financial
laws. The CFPB has examination authority over all banks and
savings institutions with more than $10 billion in assets. As the
Company is below this threshold, the OCC continues to exercise
primary examination authority over the Bank with regard to
compliance with federal consumer financial laws and regulations.
Under the Dodd-Frank Act state attorneys general are empow-
ered to enforce rules issued by the CFPB.

The Company is subject to federal consumer financial statutes
and  the  regulations  promulgated  thereunder  including,  but
not limited to:

•  The Truth-In-Lending Act, governing disclosures of credit

terms to consumer borrowers;

•  The  Equal  Credit  Opportunity  Act  (“ECOA”),  prohibiting
discrimination in connection with the extension of credit;

•  The Home Mortgage Disclosure Act (“HMDA”), requiring
home mortgage lenders, including the Bank, to make avail-
able  to  the  public  expanded  information  regarding  the
pricing of home mortgage loans, including the “rate spread”
between the annual percentage rate and the average prime
offer rate for mortgage loans of a comparable type;

•  The Fair Credit Reporting Act (“FCRA”), governing the pro-
vision of consumer information to credit reporting agencies
and the use of consumer information; and

•  The Fair Debt Collection Practices Act, governing the man-
ner in which consumer debts may be collected by collec-
tion agencies.

The Bank’s failure to comply with any of the consumer finan-
cial  laws  can  result  in  civil  actions,  regulatory  enforcement
action by the federal banking agencies and the U.S. Department
of Justice.

USA PATRIOT Act

The Bank Secrecy Act (“BSA”), as amended by the Uniting
and  Strengthening  America  by  Providing  Appropriate Tools
Required to Intercept and Obstruct Terrorism Act of 2001 (“USA
PATRIOT Act”), imposes obligations on U.S. financial institutions,
including banks and broker-dealer subsidiaries, to implement
policies,  procedures  and  controls  which  are  reasonably
designed to detect and report instances of money laundering
and the financing of terrorism. The USA PATRIOT Act requires
all financial institutions, including the Company and the Bank,
to identify their customers, adopt formal and comprehensive
anti-money laundering programs, scrutinize or prohibit alto-
gether certain transactions of special concern, and be prepared
to respond to inquiries from U.S. law enforcement agencies
concerning  their  customers  and  their  transactions. The  USA
PATRIOT Act also encourages information-sharing among finan-
cial institutions, regulators, and law enforcement authorities
by providing an exemption from the privacy provisions of the
GLB Act for financial institutions that comply with this provision.
The effectiveness of a financial institution in combating money
laundering activities is a factor to be considered in any appli-
cation submitted by the financial institution under the Bank
Merger Act, which applies to the Bank, or the BHC Act, which
applies  to  the  Company.  Failure  of  a  financial  institution  to
maintain and implement adequate programs to combat money
laundering and terrorist financing, or to comply with all of the
relevant laws or regulations, could have serious legal, financial
and reputational consequences. As of December 31, 2016, the
Company and the Bank believe that they are in compliance
with  the  BSA  and  the  USA  PATRIOT  Act,  and  implementing
regulations thereunder.

Identity Theft Prevention

The  Fair  Credit  Reporting  Act’s  (“FCRA”)  Red  Flags  Rule
requires financial institutions with covered accounts (e.g., con-
sumer bank accounts and loans) to develop, implement, and
administer an identity theft prevention program. This program
must include reasonable policies and procedures to detect sus-
picious  patterns  or  practices  that  indicate  the  possibility  of
identity theft, such as inconsistencies in personal information
or changes in account activity.

Office of Foreign Assets Control Regulation

Community Reinvestment Act of 1977

The  United  States  has  imposed  economic  sanctions  that
affect transactions with designated foreign countries, nationals,
and others. These are typically known as the “OFAC” rules based
on their administration by the U.S. Treasury Department Office
of  Foreign  Assets  Control  (“OFAC”). The  OFAC-administered
sanctions targeting countries take many different forms. Gen-
erally, they contain one or more of the following elements: (i)
restrictions on trade with or investment in a sanctioned country,
including prohibitions against direct or indirect imports from
and exports to a sanctioned country and prohibitions on “U.S.
persons” engaging in financial transactions relating to making
investments in, or providing investment-related advice or assis-
tance to, a sanctioned country; and (ii) a blocking of assets in
which the government or specially designated nationals of the
sanctioned country have an interest, by prohibiting transfers
of property subject to U.S. jurisdiction (including property in
the possession or control of U.S. persons). Blocked assets (prop-
erty  and  bank  deposits)  cannot  be  paid  out,  withdrawn,  set
off, or transferred in any manner without a license from OFAC.
Failure to comply with these sanctions could have serious legal
and reputational consequences.

Financial Privacy and Data Security

The  Company  and  the  Bank  are  subject  to  federal  laws,
including  the  Gramm-Leach-Bliley  Act  (“GLBA”)  and  certain
state laws containing consumer privacy protection provisions.
These provisions limit the ability of banks and other financial
institutions to disclose nonpublic information about consumers
to affiliated and non-affiliated third parties and limit the reuse
of  certain  consumer  information  received  from  nonaffiliated
financial institutions. These provisions require notice of privacy
policies to clients and, in some circumstances, allow consumers
to prevent disclosure of certain nonpublic personal information
to affiliates or non-affiliated third parties by means of “opt out”
or “opt in” authorizations.

The  GLBA  requires  that  financial  institutions  implement
comprehensive  written  information  security  programs  that
include administrative, technical, and physical safeguards to
protect consumer information. Further, pursuant to interpre-
tive guidance issued under the GLBA and certain state laws,
financial institutions are required to notify clients of security
breaches resulting in unauthorized access to their personal
information. The  Bank  believes  it  is  in  compliance  with  all
GLBA obligations.

The Bank is also subject to data security standards, privacy
and data breach notice requirements, primarily those issued
by the OCC.

The Bank has a responsibility under the CRA, as implemented
by OCC regulations, to help meet the credit needs of its com-
munities, including low- and moderate-income neighborhoods.
The CRA does not establish specific lending requirements or
programs for financial institutions nor does it limit an institution’s
discretion to develop the types of products and services that
it believes are best suited to its particular community, consistent
with the CRA. Regulators periodically assess the Bank’s record
of compliance with the CRA. In addition, the ECOA and the Fair
Housing  Act  prohibit  discrimination  in  lending  practices  on
the basis of characteristics specified in those statutes. The Bank’s
failure to comply with the CRA could, at a minimum, result in
regulatory restrictions on its activities and the activities of the
Company. The Bank’s latest CRA rating was “Satisfactory.”

Future Legislative Initiatives

Congress, state legislatures, and financial regulatory agencies
are  expected  to  introduce  various  legislative  and  regulatory
initiatives that are likely to impact the financial services industry,
generally. Such initiatives may include proposals to expand or
contract the powers of bank holding companies and/or depos-
itory institutions or proposals to substantially change the finan-
cial institution regulatory system. Such legislation could change
banking statutes and the operating environment of the Com-
pany in substantial and unpredictable ways. If enacted, such
legislation could increase or decrease the cost of doing busi-
ness, limit or expand permissible activities, or affect the com-
petitive  balance  among  banks,  savings  associations,  credit
unions, and other financial institutions. The Company cannot
predict  whether  any  such  legislation  will  be  enacted,  and,  if
enacted,  the  effect  that  it  or  any  implementing  regulations
would have on the financial condition or results of operations
of the Company. A change in statutes, regulations, or regulatory
policies applicable to the Company or any of its subsidiaries
could have a material effect on the business of the Company.

Employees

At  December  31,  2016,  the  Company  had  1,704  full-time
equivalent  employees. The  Company’s  employees  are  not
presently represented by any collective bargaining group.

ITEM 1A.  RISK FACTORS

There  are  risks  inherent  to  the  Company’s  business. The
material  risks  and  uncertainties  that  management  believes
affect the Company are described below. Any of the following
risks could affect the Company’s financial condition and results
of operations and could be material and/or adverse in nature.
You should consider all of the following risks together with all
of the other information in this Annual Report on Form 10-K.

Deterioration in Local Economic Conditions May 
Negatively Impact Our Financial Performance

The Company’s success depends primarily on the general
economic conditions in central and upstate New York, north-
eastern Pennsylvania, southern New Hampshire, western Mas-
sachusetts, Vermont, Maine and the specific local markets in
which the Company operates. Unlike larger national or other
regional  banks  that  are  more  geographically  diversified,  the
Company provides banking and financial services to customers
primarily in the upstate New York areas of Norwich, Syracuse,
Oneonta, Amsterdam-Gloversville, Albany, Binghamton, Utica-
Rome, Plattsburgh, Glens Falls and Ogdensburg-Massena, the
northeastern Pennsylvania areas of Scranton, Wilkes-Barre and
East Stroudsburg, Berkshire County, Massachusetts, southern
New Hampshire, Vermont and the greater Portland, Maine area.
The local economic conditions in these areas have a significant
impact on the demand for the Company’s products and services
as well as the ability of the Company’s customers to repay loans,
the value of the collateral securing loans and the stability of
the Company’s deposit funding sources.

As a lender with the majority of our loans secured by real
estate or made to businesses in New York, Pennsylvania, New
Hampshire,  Massachusetts, Vermont  and  Maine,  a  downturn
in these local economies could cause significant increases in
nonperforming loans, which could negatively impact our earn-
ings. Declines in real estate values in our market areas could

ington, DC, 20549. Information on the operation of the Public
Reference Room may be obtained by calling the SEC at 1-800-

cause any of our loans to become inadequately collateralized,
which would expose us to greater risk of loss. Additionally, a
decline in real estate values could result in the decline of orig-
inations of such loans, as most of our loans and the collateral
securing our loans, are located in those areas.

Variations in Interest Rates May Negatively Affect 
Our Financial Performance

The Company’s earnings and financial condition are largely
dependent upon net interest income, which is the difference
between interest earned from loans and investments and inter-
est paid on deposits and borrowings. The narrowing of interest
rate  spreads  could  adversely  affect  the  Company’s  earnings
and financial condition. The Company cannot predict with cer-
tainty, or control, changes in interest rates. Regional and local
economic conditions and the policies of regulatory authorities,
including monetary policies of the FRB, affect interest income
and interest expense. High interest rates could also affect the
amount  of  loans  that  the  Company  can  originate  because
higher rates could cause customers to apply for fewer mortgages
or cause depositors to shift funds from accounts that have a
comparatively lower cost to accounts with a higher cost. The
Company may also experience customer attrition due to com-
petitor pricing. If the cost of interest-bearing deposits increases
at  a  rate  greater  than  the  yields  on  interest-earning  assets
increase, net interest income will be negatively affected. Changes
in the asset and liability mix may also affect net interest income.
Similarly,  lower  interest  rates  cause  higher  yielding  assets  to
prepay and floating or adjustable rate assets to reset to lower
rates.  If  the  Company  is  not  able  to  reduce  its  funding  costs
sufficiently, due to either competitive factors or the maturity
schedule of existing liabilities, then the Company’s net interest
margin will decline.

14

NBT BANCORP 2016 FORM 10-K

Although management believes it has implemented effective
asset and liability management strategies to mitigate the poten-
tial adverse effects of changes in interest rates on the Company’s
results  of  operations,  any  substantial  or  unexpected  change
in, or prolonged change in market interest rates could have a
material adverse effect on the Company’s financial condition
and results of operations. See the section captioned “Net Interest
Income” in Item 7. Management’s Discussion and Analysis of
Financial  Condition  and  Results  of  Operations  and  Item  7A.
Quantitative  and  Qualitative  Disclosure  About  Market  Risk
located elsewhere in this report for further discussion related
to the Company’s management of interest rate risk.

Changes in the Economy or the Financial Markets 
Could Materially Affect Our Financial Performance

Downturns  in  the  United  States  or  global  economies  or
financial markets could adversely affect the demand for and
income received from the Company’s fee-based services. Rev-
enues from the trust and benefit plan administration businesses
depend in large part on the level of assets under management
and administration. Market volatility that leads customers to
liquidate investments, as well as lower asset values, can reduce
our level of assets under management and administration and
thereby decrease our investment management and adminis-
tration revenues.

Our Lending, and Particularly Our Emphasis on 
Commercial Lending, Exposes Us to the Risk of Losses 
Upon Borrower Default

As of December 31, 2016, approximately 45% of the Com-
pany’s loan portfolio consisted of commercial and industrial,
agricultural,  commercial  construction  and  commercial  real
estate loans. These types of loans generally expose a lender to
greater risk of non-payment and loss than residential real estate
loans because repayment of the loans often depends on the
successful operation of the property, the income stream of the
borrowers and, for construction loans, the accuracy of the esti-
mate of the property’s value at completion of construction and
the estimated cost of construction. Such loans typically involve
larger loan balances to single borrowers or groups of related
borrowers compared to residential real estate loans. Because
the Company’s loan portfolio contains a significant number of
commercial and industrial, agricultural, construction and com-
mercial real estate loans with relatively large balances, the dete-
rioration of one or a few of these loans could cause a significant
increase in nonperforming loans. An increase in nonperforming
loans could result in a net loss of earnings from these loans,

an increase in the provision for loan losses and/or an increase
in loan charge-offs, all of which could have a material adverse
effect on the Company’s financial condition and results of oper-
ations. See the section captioned “Loans” in Item 7. Manage-
ment’s  Discussion  and  Analysis  of  Financial  Condition  and
Results of Operations located elsewhere in this report for further
discussion  related  to  commercial  and  industrial,  agricultural,
construction and commercial real estate loans.

If Our Allowance for Loan Losses is Not Sufficient to 
Cover Actual Loan Losses, Our Earnings Will Decrease

The Company maintains an allowance for loan losses, which
is an allowance established through a provision for loan losses
charged to expense, that represents management’s best esti-
mate  of  probable  losses  that  could  be  incurred  within  the
existing portfolio of loans. The allowance, in the judgment of
management, is necessary to reserve for estimated loan losses
and risks inherent in the loan portfolio. The level of the allowance
reflects management’s continuing evaluation of industry con-
centrations; specific credit risks; loan loss experience; current
loan portfolio quality; present economic, political, environmental
and regulatory conditions and unidentified losses inherent in
the current loan portfolio. The determination of the appropriate
level of the allowance for loan losses inherently involves a high
degree of subjectivity and requires the Company to make sig-
nificant estimates of current credit risks and future trends, all
of which may undergo material changes. Changes in economic
conditions  affecting  borrowers,  new  information  regarding
existing loans, identification of additional problem loans and
other factors, both within and outside of the Company’s control,
may require an increase in the allowance for loan losses. Bank
regulatory agencies periodically review the Company’s allowance
for  loan  losses  and  may  require  an  increase  in  the  provision
for loan losses or the recognition of further loan charge-offs,
based on judgments different than those of management. In
addition, if charge-offs in future periods exceed the allowance
for loan losses, the Company may need additional provisions
to  increase  the  allowance  for  loan  losses. These  potential
increases  in  the  allowance  for  loan  losses  would  result  in  a
decrease in net income and, possibly, capital and may have a
material adverse effect on the Company’s financial condition
and results of operations. See the section captioned “Risk Man-
agement—Credit  Risk”  in  Item  7.  Management’s  Discussion
and Analysis of Financial Condition and Results of Operations
located elsewhere in this report for further discussion related
to the Company’s process for determining the appropriate level
of the allowance for loan losses.

Strong Competition Within Our Industry and Market 
Area Could Hurt Our Performance and Slow Our Growth

The Company faces substantial competition in all areas of
its operations from a variety of different competitors, many of
which are larger and may have more financial resources. Such
competitors primarily include national, regional and community
banks within the various markets in which the Company oper-
ates.  Additionally,  various  banks  continue  to  enter  or  have
announced plans to enter the market areas in which the Com-
pany currently operates. The Company also faces competition
from many other types of financial institutions, including, with-
out limitation, savings and loans, credit unions, finance com-
panies, brokerage firms, insurance companies and other financial
intermediaries. The financial services industry could become
even more competitive as a result of legislative, regulatory and
technological changes and continued consolidation. Technology
has  lowered  barriers  to  entry  and  made  it  possible  for  non-
banks to offer products and services traditionally provided by
banks, such as automatic transfer and automatic payment sys-
tems. Many of the Company’s competitors have fewer regulatory
constraints and may have lower cost structures. Additionally,
due  to  their  size,  many  competitors  may  be  able  to  achieve
economies of scale and, as a result, may offer a broader range
of  products  and  services  as  well  as  better  pricing  for  those
products and services than the Company can.

The Company’s ability to compete successfully depends on

a number of factors, including, among other things:

•  The ability to develop, maintain and build upon long-term
customer relationships based on top quality service, high
ethical standards and safe, sound assets;

•  The ability to expand the Company’s market position;

•  The scope, relevance and pricing of products and services

offered to meet customer needs and demands;

•  The rate at which the Company introduces new products,

services and technologies relative to its competitors;

•  Customer satisfaction with the Company’s level of service;

•  Industry and general economic trends; and

•  The ability to attract and retain talented employees.

Failure to perform in any of these areas could significantly
weaken  the  Company’s  competitive  position,  which  could
adversely affect the Company’s growth and profitability, which,
in turn, could have a material adverse effect on the Company’s
financial condition and results of operations.

We Are Subject to Extensive Government Regulation 
and Supervision, Which May Interfere With Our Ability 
to Conduct Our Business and May Negatively Impact 
Our Financial Results

We, primarily through the Bank and certain non-bank sub-
sidiaries, are subject to extensive federal and state regulation
and  supervision.  Banking  regulations  are  primarily  intended
to  protect  depositors’  funds,  the  Federal  Deposit  Insurance
Fund and the safety and soundness of the banking system as
a whole, not stockholders. These regulations affect the Com-
pany’s lending practices, capital structure, investment practices,
dividend  policy  and  growth,  among  other  things.  Congress
and  federal  regulatory  agencies  continually  review  banking
laws, regulations and policies for possible changes. Changes
to statutes, regulations or regulatory policies, including changes
in interpretation or implementation of statutes, regulations or
policies, could affect the Company in substantial and unpre-
dictable  ways.  Such  changes  could  subject  the  Company  to
additional costs, limit the types of financial services and products
the Company may offer, and/or limit the pricing the Company
may charge on certain banking services, among other things.
Compliance personnel and resources may increase our costs
of operations and adversely impact our earnings.

Failure  to  comply  with  laws,  regulations  or  policies  could
result in sanctions by regulatory agencies, civil money penalties
and/or reputation damage, which could have a material adverse
effect on our business, financial condition and results of oper-
ations. While the Company has policies and procedures designed
to prevent any such violations, there can be no assurance that
such violations will not occur. See the section captioned “Super-
vision  and  Regulation”  in  Item  1.  Business  of  this  report  for
further information.

We Will be Subject to Heightened Regulatory 
Requirements if We Exceed $10 Billion in Total 
Consolidated Assets

Based on our historical growth rates and current size, it is
possible that our total assets could exceed $10 billion dollars
in the near future. The Dodd-Frank Act and its implementing
regulations  impose  enhanced  supervisory  requirements  on
bank  holding  companies  with  more  than  $10  billion  in  total
consolidated  assets.  For  bank  holding  companies  with  more
than $10 billion but less than $50 billion in total consolidated
assets such requirements include, among other things:

•  Compliance with the FRB’s annual stress testing requirements;

•  Increased capital, leverage, liquidity and risk management

standards;

16

NBT BANCORP 2016 FORM 10-K

•  Examinations  by  the  CFPB  for  compliance  with  federal

consumer financial protection laws and regulations;

•  Limits on interchange fees on debit cards; and

•  Changes to the FDIC deposit insurance assessments cal-
culation that would increase our insurance premium costs.

Federal financial regulators may require us to take actions
to prepare for compliance before we exceed $10 billion in total
consolidated assets. Our regulators may consider our preparation
for compliance with these regulatory requirements when exam-
ining our operations or considering any request for regulatory
approval. We  may,  therefore,  incur  compliance  costs  before
we reach $10 billion in total consolidated assets and may be
required  to  maintain  the  additional  compliance  procedures
even if we do not grow at the anticipated rate or at all.

Failure to comply with these new requirements may nega-
tively impact the results of our operations and financial condi-
tion. To ensure compliance, we will be required to investment
significant resources, which may necessitate hiring additional
personnel and implementing additional internal controls. These
additional compliance costs may have a material adverse effect
on our business, results of operations and financial condition.

The Company is Subject to Liquidity Risk Which Could 
Adversely Affect Net Interest Income and Earnings

The purpose of the Company’s liquidity management is to
meet the cash flow obligations of its customers for both deposits
and loans. The primary liquidity measurement the Company
utilizes is called basic surplus, which captures the adequacy of
the Company’s access to reliable sources of cash relative to the
stability of its funding mix of average liabilities. This approach
recognizes the importance of balancing levels of cash flow liq-
uidity from short and long-term securities with the availability
of dependable borrowing sources which can be accessed when
necessary. However, competitive pressure on deposit pricing
could result in a decrease in the Company’s deposit base or an
increase in funding costs. In addition, liquidity will come under
additional  pressure  if  loan  growth  exceeds  deposit  growth.
These  scenarios  could  lead  to  a  decrease  in  the  Company’s
basic surplus measure below the minimum policy level of 5%.
To manage this risk, the Company has the ability to purchase
brokered time deposits, borrow against established borrowing
facilities with other banks (Federal funds) and enter into repur-
chase agreements with investment companies. Depending on
the level of interest rates, the Company’s net interest income,
and therefore earnings, could be adversely affected. See the
section captioned “Liquidity Risk” in Item 7.

Our Ability to Service Our Debt, Pay Dividends and 
Otherwise Pay Our Obligations as They Come Due 
is Substantially Dependent on Capital Distributions 
From Our Subsidiaries

The Company is a separate and distinct legal entity from
its subsidiaries. It receives substantially all of its revenue from
dividends from its subsidiaries. These dividends are the prin-
cipal source of funds to pay dividends on the Company’s com-
mon stock and interest and principal on the Company’s debt.
Various  federal  and/or  state  laws  and  regulations  limit  the
amount of dividends that the Bank may pay to the Company.
Also, the Company’s right to participate in a distribution of
assets  upon  a  subsidiary’s  liquidation  or  reorganization  is
subject to the prior claims of the subsidiary’s creditors. In the
event the Bank is unable to pay dividends to the Company,
the Company may not be able to service debt, pay obligations
or pay dividends on the Company’s common stock. The inabil-
ity to receive dividends from the Bank could have a material
adverse effect on the Company’s business, financial condition
and results of operations.

A Breach of Information Security, Including as a Result 
of Cyber Attacks, Could Disrupt Our Business and 
Impact Our Earnings

We depend upon data processing, communication and infor-
mation exchange on a variety of computing platforms and net-
works and over the internet. In addition, we rely on the services
of a variety of vendors to meet our data processing and com-
munication needs. Despite existing safeguards, we cannot be
certain  that  all  of  our  systems  are  free  from  vulnerability  to
attack or other technological difficulties or failures. If information
security is breached or difficulties or failures occur, despite the
controls we and our third party vendors have instituted, infor-
mation  can  be  lost  or  misappropriated,  resulting  in  financial
loss  or  costs  to  us,  reputational  harm  or  damages  to  others.
Such  costs  or  losses  could  exceed  the  amount  of  insurance
coverage, if any, which would adversely affect our earnings.

The Company May be Adversely Affected by Fraud

As a financial institution, the Company is inherently exposed
to  operational  risk  in  the  form  of  theft  and  other  fraudulent
activity by employees, customers, and other third parties tar-
geting the Company and/or the Company’s customers or data.
Such activity may take many forms, including check fraud, elec-
tronic fraud, wire fraud, phishing, social engineering and other
dishonest acts.

Although  the  Company  devotes  substantial  resources  to
maintaining effective policies and internal controls to identify
and prevent such incidents, given the increasing sophistication
of possible perpetrators, the Company may experience financial
losses or reputational harm as a result of fraud.

We Continually Encounter Technological Change and 
the Failure to Understand and Adapt to These Changes 
Could Hurt Our Business

The  financial  services  industry  is  continually  undergoing
rapid technological change with frequent introductions of new
technology-driven products and services. The effective use of
technology increases efficiency and enables financial institutions
to better serve customers and to reduce costs. The Company’s
future success depends, in part, upon its ability to address the
needs of its customers by using technology to provide products
and services that will satisfy customer demands, as well as to
create  additional  efficiencies  in  the  Company’s  operations.
Many of the Company’s competitors have substantially greater
resources to invest in technological improvements. The Company
may  not  be  able  to  effectively  implement  new  technology-
driven  products  and  services  or  be  successful  in  marketing
these  products  and  services  to  its  customers.  Failure  to  suc-
cessfully keep pace with technological changes affecting the
financial services industry could have a material adverse impact
on the Company’s business and, in turn, the Company’s financial
condition and results of operations.

The Company Relies on Third Parties to Provide 
Key Components of its Business Infrastructure

The Company relies on third parties to provide key compo-
nents for its business operations, such as data processing and
storage, recording and monitoring transactions, online banking
interfaces  and  services,  internet  connections,  and  network
access. While  the  Company  selects  these  third-party  vendors
carefully, it does not control their actions. Any problems caused
by these third parties, including those resulting from breakdowns
or other disruptions in communication services provided by a
vendor, failure of a vendor to handle current or higher volumes,
cyber-attacks  and  security  breaches  at  a  vendor,  failure  of  a
vendor to provide services for any reason, or poor performance
of services by a vendor, could adversely affect the Company’s
ability  to  deliver  products  and  services  to  its  customers  and
otherwise conduct its business. Financial or operational difficulties
of a third-party vendor could also hurt the Company’s operations
if those difficulties interfere with the vendor’s ability to serve
the Company. Replacing these third party vendors also could
create significant delays and expense that adversely affect the
Company’s business and performance.

The Possibility of the Economy’s Return to Recessionary 
Conditions and the Possibility of Further Turmoil or 
Volatility in the Financial Markets Would Likely Have 
an Adverse Effect on Our Business, Financial Position 
and Results of Operations

The economy in the United States and globally has experienced
volatility in recent years and may continue to do so for the fore-
seeable future. There can be no assurance that economic con-
ditions will not worsen. Unfavorable or uncertain economic
conditions can be caused by declines in economic growth, busi-
ness activity or investor or business confidence, limitations on
the availability or increases in the cost of credit and capital,
increases in inflation or interest rates, the timing and impact of
changing governmental policies, natural disasters, terrorist attacks,
acts of war or a combination of these or other factors. A worsening
of business and economic conditions recovery could have adverse
effects on our business, including the following:

•  Investors may have less confidence in the equity markets
in general and in financial services industry stocks in par-
ticular, which could place downward pressure on the Com-
pany’s stock price and resulting market valuation;

•  Economic and market developments may further affect
consumer and business confidence levels and may cause
declines in credit usage and adverse changes in payment
patterns, causing increases in delinquencies and default
rates;

•  The Company’s ability to assess the creditworthiness of its
customers may be impaired if the models and approaches
the Company uses to select, manage and underwrite its
customers become less predictive of future behaviors;

•  The Company could suffer decreases in demand for loans
or other financial products and services or decreased deposits
or other investments in accounts with the Company;

•  Customers of the Company’s trust and benefit plan admin-
istration  business  may  liquidate  investments,  which
together with lower asset values, may reduce the level of
assets under management and administration and thereby
decrease  the  Company’s  investment  management  and
administration revenues;

•  Competition in the financial services industry could inten-
sify as a result of the increasing consolidation of financial
services  companies  in  connection  with  current  market
conditions or otherwise; and;

•  The value of loans and other assets or collateral securing

loans may decrease.

We are Subject to Other-Than-Temporary 
Impairment Risk Which Could Negatively Impact 
Our Financial Performance

The Company recognizes an impairment charge when the
decline  in  the  fair  value  of  equity,  debt  securities  and  cost-
method investments below their cost basis are judged to be
other-than-temporary. Significant judgment is used to identify
events  or  circumstances  that  would  likely  have  a  significant
adverse effect on the future use of the investment. The Company
considers various factors in determining whether an impairment
is other-than-temporary, including the severity and duration
of the impairment, forecasted recovery, the financial condition
and near-term prospects of the investee, whether the Company
has the intent to sell and whether it is more likely than not it
will be forced to sell the security in question. Information about
unrealized gains and losses is subject to changing conditions.
The values of securities with unrealized gains and losses will
fluctuate,  as  will  the  values  of  securities  that  we  identify  as
potentially  distressed.  Our  current  evaluation  of  other-than-
temporary  impairments  reflects  our  intent  to  hold  securities
for a reasonable period of time sufficient for a forecasted recov-
ery of fair value. However, our intent to hold certain of these
securities may change in future periods as a result of facts and
circumstances  impacting  a  specific  security.  If  our  intent  to
hold a security with an unrealized loss changes and we do not
expect the security to fully recover prior to the expected time
of disposition, we will write down the security to its fair value
in the period that our intent to hold the security changes.

The process of evaluating the potential impairment of good-
will and other intangibles is highly subjective and requires sig-
nificant judgment. The Company estimates the expected future
cash flows of its various businesses and determines the carrying
value of these businesses. The Company exercises judgment
in assigning and allocating certain assets and liabilities to these
businesses. The Company then compares the carrying value,
including  goodwill  and  other  intangibles,  to  the  discounted
future cash flows. If the total of future cash flows is less than
the carrying amount of the assets, an impairment loss is rec-
ognized based on the excess of the carrying amount over the
fair value of the assets. Estimates of the future cash flows asso-
ciated with the assets are critical to these assessments. Changes
in these estimates based on changed economic conditions or
business strategies could result in material impairment charges
and therefore have a material adverse impact on the Company’s
financial condition and performance.

The Risks Presented by Acquisitions Could Adversely 
Affect Our Financial Condition and Results of Operations

The  business  strategy  of  the  Company  has  included  and
may  continue  to  include  growth  through  acquisition.  Any
future acquisitions will be accompanied by the risks commonly
encountered in acquisitions. These risks may include, among
other things:

•  Our ability to realize anticipated cost savings;

•  The difficulty of integrating operations and personnel, the

loss of key employees;

•  The potential disruption of our or the acquired company’s
ongoing  business  in  such  a  way  that  could  result  in
decreased revenues, the inability of our management to
maximize our financial and strategic position;

•  The inability to maintain uniform standards, controls, pro-

cedures and policies; and

•  The impairment of relationships with the acquired com-
pany’s employees and customers as a result of changes
in ownership and management.

We cannot provide any assurance that we will be successful
in overcoming these risks or any other problems encountered
in connection with acquisitions. Our inability to overcome these
risks could have an adverse effect on the achievement of our
business strategy and results of operations.

There are Substantial Risks and Uncertainties 
Associated With the Introduction or Expansion 
of Lines of Business or New Products and Services 
Within Existing Lines of Business

From time to time, the Company may implement new lines
of business or offer new products and services within existing
lines of business. There are substantial risks and uncertainties
associated with these efforts, particularly in instances where
the markets are not fully developed. In developing and mar-
keting new lines of business and/or new products and services,
the Company may invest significant time and resources. Initial
timetables  for  the  introduction  and  development  of  new
lines of business and/or new products or services may not be
achieved  and  price  and  profitability  targets  may  not  prove
attainable. External factors, such as compliance with regulations,
competitive alternatives, and shifting market preferences, may
also  impact  the  successful  implementation  of  a  new  line  of
business or a new product or service. Furthermore, any new

NBT BANCORP 2016 FORM 10-K

19

line of business and/or new product or service could have a
significant impact on the effectiveness of the Company’s system
of internal controls. Failure to successfully manage these risks
in the development and implementation of new lines of business
or  new  products  or  services  could  have  a  material  adverse
effect  on  the  Company’s  business,  results  of  operations,  and
financial condition.

Our Controls and Procedures May Fail or be 
Circumvented, Which May Result in a Material 
Adverse Effect on Our Business

Management  regularly  reviews  and  updates  our  internal
controls,  disclosure  controls  and  procedures  and  corporate
governance policies and procedures. Any system of controls,
however well designed and operated, is based in part on certain
assumptions and can provide only reasonable, not absolute,
assurances that the objectives of the system are met. Any failure
or circumvention of the controls and procedures or failure to
comply  with  regulations  related  to  controls  and  procedures
could have a material adverse effect on our business, results
of operations and financial condition.

We Are Exposed to Risk of Environmental Liabilities 
With Respect to Properties to Which We Obtain Title

A significant portion of our loan portfolio at December 31,
2016 was secured by real estate. In the course of our business,
we  may  foreclose  and  take  title  to  real  estate  and  could  be
subject to environmental liabilities with respect to these prop-
erties. We may be held liable to a government entity or to third
parties for property damage, personal injury, investigation and
clean-up  costs  incurred  by  these  parties  in  connection  with
environmental contamination, or may be required to clean up
hazardous or toxic substances, or chemical releases at a property.
The costs associated with investigation and remediation activities
could be substantial. In addition, if we are the owner or former
owner of a contaminated site, we may be subject to common
law claims by third parties based on damages and costs resulting
from environmental contamination emanating from the prop-
erty. These costs and claims could adversely affect our business,
results of operations and prospects.

We May be Adversely Affected by the Soundness 
of Other Financial Institutions Including the 
FHLB of New York

Our ability to engage in routine funding transactions could
be adversely affected by the actions and commercial soundness
of  other  financial  institutions.  Financial  services  companies
are interrelated as a result of trading, clearing, counterparty
or  other  relationships. We  have  exposure  to  many  different

industries and counterparties, and we routinely execute trans-
actions with counterparties in the financial services industry,
including brokers and dealers, commercial banks, investment
banks, mutual and hedge funds and other institutional clients.
As  a  result,  defaults  by,  or  even  rumors  or  questions  about,
one or more financial services companies, or the financial serv-
ices industry generally, have led to market-wide liquidity prob-
lems  and  could  lead  to  losses  or  defaults  by  us  or  by  other
institutions.  Many  of  these  transactions  expose  us  to  credit
risk  in  the  event  of  default  of  our  counterparty  or  client.  In
addition, our credit risk may be exacerbated if the collateral
held by us cannot be realized or is liquidated at prices not suf-
ficient  to  recover  the  full  amount  of  the  loan  or  derivative
exposure due us. There is no assurance that any such losses
would not materially and adversely affect our business, financial
condition or results of operations.

The Company owns common stock of FHLB of New York in
order  to  qualify  for  membership  in  the  FHLB  system,  which
enables it to borrow funds under the FHLB of New York’s advance
program. The carrying value and fair market value of our FHLB
of New York common stock was $31.8 million as of December
31,  2016. There  are  11  branches  of  the  FHLB,  including  New
York, which are jointly liable for the consolidated obligations
of the FHLB system. To the extent that one FHLB branch cannot
meet its obligations to pay its share of the system’s debt, other
FHLB branches can be called upon to make the payment. Any
adverse effects on the FHLB of New York could adversely affect
the value of our investment in its common stock and negatively
impact our results of operations.

Provisions of Our Certificate of Incorporation and Bylaws,
as Well as Delaware Law and Certain Banking Laws, 
Could Delay or Prevent a Takeover of Us by a Third Party

Provisions of the Company’s certificate of incorporation and
bylaws, the corporate law of the State of Delaware and state
and federal banking laws, including regulatory approval require-
ments, could delay, defer or prevent a third party from acquiring
the Company, despite the possible benefit to the Company’s
stockholders,  or  otherwise  adversely  affect  the  market  price
of  the  Company’s  common  stock. These  provisions  include
supermajority voting requirements for certain business com-
binations  and  advance  notice  requirements  for  nominations
for election to the Company’s board of directors and for pro-
posing  matters  that  stockholders  may  act  on  at  stockholder
meetings. In addition, the Company is subject to Delaware law,
which among other things prohibits the Company from engag-
ing in a business combination with any interested stockholder
for a period of three years from the date the person became
an  interested  stockholder  unless  certain  conditions  are  met.

20

NBT BANCORP 2016 FORM 10-K

These provisions may discourage potential takeover attempts,
discouraging bids for the Company’s common stock at a pre-
mium over market price or adversely affect the market price
of and the voting and other rights of the holders of the Com-
pany’s common stock. These provisions could also discourage
proxy  contests  and  make  it  more  difficult  for  you  and  other
stockholders to elect directors other than candidates nominated
by the Board.

The Company’s Common Stock Price 
May Fluctuate Significantly

The  Company’s  common  stock  price  constantly  changes,
and has increased substantially since the U.S. Presidential elec-
tion  in  November  2016. The  market  price  of  the  Company’s
common  stock  may  continue  to  fluctuate  significantly  in
response to a number of factors including, but not limited to:

•  The political climate and whether the proposed policies
of  the  new  Presidential  administration  in  the  U.S.  that
have affected market prices for financial institution stocks
are successfully implemented;

•  Changes in securities analysts’ recommendations or expec-

tations of financial performance;

•  Volatility of stock market prices and volumes;

•  Incorrect information or speculation;

•  Changes in industry valuations;

•  Variations in operating results from general expectations;

•  Actions taken against the Company by various regulatory

agencies;

•  Changes in authoritative accounting guidance;

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

•  Changes in general domestic economic conditions such
as  inflation  rates,  tax  rates,  unemployment  rates,  labor
and healthcare cost trend rates, recessions and changing
government policies, laws and regulations; and

•  Severe weather, natural disasters, acts of war or terrorism

and other external events.

There May be Future Sales or Other Dilution 
of the Company’s Equity, Which May Adversely 
Affect the Market Price of the Company’s Stock

The Company is not restricted from issuing additional com-
mon  stock,  including  any  securities  that  are  convertible  into
or exchangeable for, or that represent the right to receive, com-
mon stock. The Company also grants a significant number of
shares of common stock to employees and directors under the
Company’s incentive plan each year. The issuance of any addi-
tional  shares  of  the  Company’s  common  stock  or  preferred
stock or securities convertible into, exchangeable for or that
represent the right to receive common stock, or the exercise
of such securities could be substantially dilutive to stockholders
of  the  Company’s  common  stock.  Holders  of  the  Company’s
common  stock  have  no  preemptive  rights  that  entitle  such
holders to purchase their pro rata share of any offering of shares
or any class or series. Because the Company’s decision to issue
securities in any future offering will depend on market condi-
tions, its acquisition activity and other factors, the Company
cannot predict or estimate the amount, timing or nature of its
future  offerings. Thus,  the  Company’s  stockholders  bear  the
risk  of  the  Company’s  future  offerings  reducing  the  market
price of the Company’s common stock and diluting their stock
holdings in the Company.

Stock Performance Graph

The following stock performance graph compares the cumu-
lative total stockholder return (i.e., price change, reinvestment
of cash dividends and stock dividends received) on our Common
Stock against the cumulative total return of the NASDAQ Stock
Market  (U.S.  Companies)  Index  and  the  KBW  Regional  Bank

Index (Peer Group). The stock performance graph assumes that
$100 was invested on December 31, 2011. The graph further
assumes the reinvestment of dividends into additional shares
of  the  same  class  of  equity  securities  at  the  frequency  with
which dividends are paid on such securities during the relevant
fiscal year. The yearly points marked on the horizontal axis cor-
respond to December 31 of that year. We calculate each of the
referenced indices in the same manner. All are market-capital-
ization-weighted indices, so companies judged by the market
to be more important (i.e., more valuable) count for more in
all indices.

Dividends

We depend primarily upon dividends from our subsidiaries
for a substantial part of our revenue. Accordingly, our ability
to pay dividends to our stockholders depends primarily upon
the receipt of dividends or other capital distributions from our
subsidiaries. Payment of dividends to the Company from the
Bank  is  subject  to  certain  regulatory  and  other  restrictions.
Under  OCC  regulations,  the  Bank  may  pay  dividends  to  the
Company without prior regulatory approval so long as it meets
its applicable regulatory capital requirements before and after
payment of such dividends and its total dividends do not exceed
its net income to date over the calendar year plus retained net
income over the preceding two years. At December 31, 2016,
the Bank was in compliance with all applicable minimum capital
requirements and had the ability to pay dividends of $102.5
million to the Company without the prior approval of the OCC.
If the capital of the Company is diminished by depreciation
in the value of its property or by losses, or otherwise, to an
amount less than the aggregate amount of the capital rep-
resented  by  the  issued  and  outstanding  stock  of  all  classes

having a preference upon the distribution of assets, no divi-
dends may be paid out of net profits until the deficiency in the
amount of capital represented by the issued and outstanding
stock of all classes having a preference upon the distribution
of assets has been repaired. See the section captioned “Super-
vision and Regulation” in Item 1. Business and Note 15 to the
consolidated financial statements is included in Item 8. Financial
Statements and Supplementary Data, which are located else-
where in this report.

NBT Board of Directors authorized a new repurchase program
for NBT to repurchase up to 1,000,000 shares of its outstanding

The Company cautions readers not to place undue reliance
on any forward-looking statements, which speak only as of the
date made, and advises readers that various factors including,
but  not  limited  to,  those  described  above,  could  affect  the
Company’s financial performance and could cause the Com-
pany’s  actual  results  or  circumstances  for  future  periods  to
differ materially from those anticipated or projected.

Except as required by law, the Company does not undertake,
and specifically disclaims any obligations to, publicly release
any revisions that may be made to any forward-looking state-
ments to reflect the occurrence of anticipated or unanticipated
events or circumstances after the date of such statements.

General

The  financial  review  which  follows  focuses  on  the  factors
affecting  the  consolidated  financial  condition  and  results  of
operations of the Company and its wholly-owned subsidiaries,
the Bank, NBT Financial Services and NBT Holdings during 2016
and, in summary form, the preceding two years. Collectively,
the Registrant and its subsidiaries are referred to herein as “the
Company.” Net interest margin is presented in this discussion
on  a  fully  taxable  equivalent  (“FTE”)  basis.  Average  balances
discussed are daily averages unless otherwise described. The
audited  consolidated  financial  statements  and  related  notes
as of December 31, 2016 and 2015 and for each of the years in
the  three-year  period  ended  December  31,  2016  should  be
read in conjunction with this review. Amounts in prior period
consolidated  financial  statements  are  reclassified  whenever
necessary to conform to the 2016 presentation.

Critical Accounting Policies

The Company has identified policies as being critical because
they require management to make particularly difficult, sub-
jective and/or complex judgments about matters that are inher-
ently uncertain and because of the likelihood that materially
different amounts would be reported under different conditions
or  using  different  assumptions. These  policies  relate  to  the
allowance  for  loan  losses,  pension  accounting,  provision  for
income taxes and impairment of goodwill and intangible assets.

Management  of  the  Company  considers  the  accounting
policy relating to the allowance for loan losses to be a critical
accounting policy given the uncertainty in evaluating the level
of the allowance required to cover credit losses inherent in the
loan portfolio and the material effect that such judgments can
have on the results of operations. While management’s current
evaluation of the allowance for loan losses indicates that the
allowance is adequate, under adversely different conditions or
assumptions,  the  allowance  may  need  to  be  increased.  For
example, if historical loan loss experience significantly worsened
or  if  current  economic  conditions  significantly  deteriorated,
additional provision for loan losses would be required to increase
the allowance. In addition, the assumptions and estimates used
in the internal reviews of the Company’s nonperforming loans
and potential problem loans have a significant impact on the
overall analysis of the adequacy of the allowance for loan losses.
While management has concluded that the current evaluation
of  collateral  values  is  reasonable  under  the  circumstances,  if
collateral  values  were  significantly  lower,  the  Company’s
allowance  for  loan  loss  policy  would  also  require  additional
provision for loan losses.

Management  is  required  to  make  various  assumptions  in
valuing  its  pension  assets  and  liabilities. These  assumptions
include the expected rate of return on plan assets, the discount
rate,  and  the  rate  of  increase  in  future  compensation  levels.
Changes to these assumptions could impact earnings in future
periods. The Company takes into account the plan asset mix,
funding obligations, and expert opinions in determining the
various rates used to estimate pension expense. The Company
also  considers  the  Citigroup  Pension  Liability  Index,  market
interest rates and discounted cash flows in setting the appro-
priate discount rate. In addition, the Company reviews expected
inflationary and merit increases to compensation in determining
the rate of increase in future compensation levels.

The Company is subject to examinations from various taxing
authorities. Such examinations may result in challenges to the
tax return treatment applied by the Company to specific trans-
actions. Management believes that the assumptions and judg-
ments used to record tax-related assets or liabilities have been

NBT BANCORP 2016 FORM 10-K

27

appropriate. Should tax laws change or the taxing authorities
determine that management’s assumptions were inappropriate,
an adjustment may be required which could have a material
effect on the Company’s results of operations.

As a result of acquisitions, the Company has acquired good-
will and identifiable intangible assets. Goodwill represents the
cost of acquired companies in excess of the fair value of net
assets  at  the  acquisition  date.  Goodwill  is  evaluated  at  least
annually or when business conditions suggest that an impair-
ment may have occurred. Goodwill will be reduced to its carrying
value through a charge to earnings if impairment exists. Core
deposits and other identifiable intangible assets are amortized
to expense over their estimated useful lives. The determination
of whether or not impairment exists is based upon discounted
cash flow modeling techniques that require management to
make estimates regarding the amount and timing of expected
future cash flows. It also requires them to select a discount rate
that reflects the current return requirements of the market in
relation to present risk-free interest rates, required equity market
premiums  and  Company-specific  risk  indicators,  all  of  which
are susceptible to change based on changes in economic con-
ditions and other factors. Future events or changes in the esti-
mates used to determine the carrying value of goodwill and
identifiable intangible assets could have a material impact on
the Company’s results of operations.

The  Company’s  policies  on  the  allowance  for  loan  losses,
pension accounting, provision for income taxes, goodwill and
intangible assets are disclosed in Note 1 to the consolidated
financial  statements.  A  more  detailed  description  of  the
allowance for loan losses is included in the section captioned
“Risk Management—Credit Risk” in Item 7. Management’s Dis-
cussion and Analysis of Financial Condition and Results of Oper-
ations  of  this  Form  10-K.  All  significant  pension  accounting
assumptions,  income  tax  assumptions,  and  intangible  asset
assumptions and detail are disclosed in Notes 13, 12 and 7 to
the consolidated financial statements, respectively. All account-
ing policies are important, and as such, the Company encourages
the reader to review each of the policies included in Note 1 to
obtain a better understanding of how the Company’s financial
performance is reported.

Non-GAAP Measures

This Annual Report on Form 10-K contains financial infor-
mation determined by methods other than in accordance with
accounting principles generally accepted in the United States
of America (“GAAP”). These measures adjust GAAP measures
to exclude the effects of acquisition related intangible amorti-
zation expense on earnings and equity as well as providing a
fully  taxable  equivalent  yield  on  securities  and  loans. Where
non-GAAP disclosures are used in this Annual Report on Form
10-K, the comparable GAAP measure, as well as a reconciliation
to the comparable GAAP measure, is provided in the accom-
panying  tables.  Management  believes  that  these  non-GAAP
measures provide useful information that is important to an
understanding of the operating results of the Company’s core
business as well as provide information standard in the financial
institution industry. Non-GAAP measures should not be con-
sidered a substitute for financial measures determined in accor-
dance with GAAP and investors should consider the Company’s
performance and financial condition as reported under GAAP
and all other relevant information when assessing the perform-
ance or financial condition of the Company.

Overview

Significant  factors  management  reviews  to  evaluate  the
Company’s operating results and financial condition include,
but  are  not  limited  to:  net  income  and  earnings  per  share,
return on assets and equity, net interest margin, noninterest
income, operating expenses, asset quality indicators, loan and
deposit  growth,  capital  management,  liquidity  and  interest
rate sensitivity, enhancements to customer products and serv-
ices, technology advancements, market share and peer com-
parisons. The following information should be considered in
connection with the Company’s results for the fiscal year ended
December 31, 2016:

•  Net income for 2016 was $78.4 million, the highest in the
Company’s history, and up from $76.4 million in 2015.

•  Net interest margin for 2016 declined 7 basis points as a
result  of  the  continued  low  rate  environment  on  loans
and investments.

28

NBT BANCORP 2016 FORM 10-K

•  Asset quality indicators showed stability from last year:

–  Nonperforming loans were 0.65% at December 31, 2016

compared to 0.64% at December 31, 2015;

–  Past  due  loans  to  total  loans  increased  to  0.64%  at
December 31, 2016 from 0.62% at December 31, 2015;
and

–  Net charge-offs to average loans were 0.39% for 2016

compared to 0.38% in 2015.

•  Continued  demand  deposit  growth  strategies  resulting
in 10.1% growth in average deposits from 2015 to 2016.

•  Increased efforts to grow noninterest income with focus
on organic growth of our wealth management businesses;
and

•  Improved operating efficiencies resulting in flat noninterest

expense year over year.

The Company reported net income of $78.4 million or $1.80
per diluted share for 2016, up 2.6% from net income of $76.4
million or $1.72 per diluted share for 2015. Net interest income
was $264.4 million for the year ended December 31, 2016, up
$11.8 million, or 4.7% from $252.6 million in 2015. FTE net inter-
est margin was 3.43% for the year ended December 31, 2016,
down from 3.50% for the year ended December 31, 2015. Aver-
age interest earning assets were up $510.5 million, or 7.0%, for
the year ended December 31, 2016 as compared to 2015. The
provision for loan losses totaled $25.4 million for the year ended
December 31, 2016, up $7.1 million, or 39.1%, from $18.3 million
for the year ended December 31, 2015.

2017 Outlook

The Company’s 2016 earnings reflected the Company’s con-
tinued ability to manage through the existing economic con-
ditions and challenges in the financial services industry, while
investing in the Company’s future. Since the 2016 U.S. Presidential

election, financial services stock prices have increased substan-
tially  based  in  part  on  assumptions  related  to  interest  rates,
deregulation and tax policy, the extent, timing and impact of
which  remains  uncertain.  Significant  items  that  may  have  an
impact on 2017 results include:

•  Improving economic conditions may cause interest rates
to rise. This would result in principal and interest payments
on  currently  outstanding  loans  and  investments  being
reinvested at higher rates. In addition, rising market rates
would likely increase deposit and borrowing costs from
current  low  levels. This  could  potentially  offset  or  more
than  offset  the  benefits  of  higher  rates  on  our  earning
assets. The magnitude and timing of interest rate increases,
along with the shape of the yield curve, will impact net
interest income in 2017.

•  The new administration’s proposed regulatory relief and
income tax reform could have positive impacts on com-
pliance costs and income tax expense for both the Com-
pany and our customers. The extent and speed of these
potential  reforms  will  determine  the  significance  of  the
potential benefits in 2017.

•  Generally, political turmoil, both in the United States and
globally, may give rise to continued market volatility that
could impact both the Company’s stock price and interest
rates.

•  The Company’s continued focus on long-term strategies
including growth in the New England markets, diversifi-
cation of revenue, improving operating efficiencies and
investing in technology.

•  The Company’s 2017 outlook is subject to factors in addi-
tion to those identified above and those risks and uncer-
tainties  that  could  impact  the  Company’s  future  results
are explained in ITEM 1A. RISK FACTORS.

Asset/Liability Management

The  Company  attempts  to  maximize  net  interest  income
and  net  income,  while  actively  managing  its  liquidity  and
interest rate sensitivity through the mix of various core deposit
products  and  other  sources  of  funds,  which  in  turn  fund  an
appropriate mix of earning assets. The changes in the Company’s
asset mix and sources of funds, and the resulting impact on
net interest income, on a fully tax equivalent basis, are discussed

TO 2015 OPERATING RESULTS

Net Interest Income

Net interest income was $264.4 million for the year ended
December 31, 2016, up $11.8 million from 2015. Fully taxable
equivalent (“FTE”) net interest margin was 3.43% for the year
ended December 31, 2016, down from 3.50% for the year ended
December 31, 2015. Average interest earning assets were up
$510.5 million, or 7.0%, for the year ended December 31, 2016
as compared to 2015. This increase from last year was driven
primarily  by  $314.9,  or  5.4%,  period  end  loan  growth  and  a
$220.7 million, or 13.4%, increase in investment securities in
2016. The benefit of earning asset growth was partially offset
by a 6 basis point (“bp”) decrease in earning assets yields, driven
by a 5 bp decrease in loan yields from 2015 to 2016. Average
interest  bearing  liabilities  increased  $330.7  million,  or  6.4%,
from  the  year  ended  December  31,  2015  to  the  year  ended

December 31, 2016. Total average deposits increased $373.2
million, or 5.8%, for the year ended December 31, 2016 as com-
pared to the prior year driven primarily by a 10.1% increase in
noninterest bearing demand deposits, as well as increases in
money  market  deposit  accounts,  NOW  and  savings  deposits
in 2016. Average short-term borrowings increased $157.8 mil-
lion  for  the  year  ended  December  31,  2016  as  compared  to
the prior year funding earning asset growth. The rates paid on
interest bearing liabilities increased by 1 bp for the year ended
December 31, 2016 as compared to 2015. The following table
presents changes in interest income, on a FTE basis, and interest
expense attributable to changes in volume (change in average
balance multiplied by prior year rate), changes in rate (change
in rate multiplied by prior year volume), and the net change in
net interest income. The net change attributable to the com-
bined impact of volume and rate has been allocated to each
in proportion to the absolute dollar amounts of change.

Loans and Corresponding Interest 
and Fees on Loans

The average balance of loans increased by approximately
$291.7 million, or 5.1%, from 2015 to 2016. The yield on average
loans decreased from 4.22% in 2015 to 4.17% in 2016, as loan
rates declined due to the continued low rate environment in
2016.  FTE  interest  income  from  loans  increased  3.8%,  from
$242.6 million in 2015 to $251.7 million in 2016. This increase
was due to the decrease in yields, offset by the increase in aver-
age loan balances.

Composition of Loan Portfolio

Total loans increased $314.9 million, or 5.4%, from December
31, 2015 to December 31, 2016. Increases in commercial real
estate loans and commercial loans were the primary drivers of
the increase in total loans from 2015 as the Company experi-
enced  strong  originations  in  2016  in  the  upstate  New York,
Pennsylvania and New England markets.

The following table reflects the loan portfolio by major cat-

egories as of December 31 for the years indicated:

Residential real estate mortgages consist primarily of loans
secured by first or second deeds of trust on primary residences.
Loans in the commercial and agricultural categories, including
commercial and agricultural real estate mortgages, consist pri-
marily of short-term and/or floating rate loans made to small
and medium-sized entities. Consumer loans include $1.2 billion
of  indirect  installment  loans  to  individuals  which  is  secured
by automobiles and other personal property including marine,
recreational  vehicles  and  manufactured  housing.  Consumer
loans  also  consist  of  direct  installment  loans  to  individuals
secured by similar collateral. Although automobile loans have
generally  been  originated  through  dealers,  all  applications
submitted through dealers are subject to the Company’s normal
underwriting and loan approval procedures. In addition, the
consumer  loan  portfolio  as  of  December  31,  2016  includes
$374.9 million of unsecured consumer loans across a national

footprint  originated  through  our  relationship  with  a  leading
national  fintech  company  that  began  nine  years  ago  as  the
result of our investment in Springstone Financial LLC (“Spring-
stone”).  Advances  of  credit  through  this  specialty  lending
business  line  are  to  prime  borrowers  and  are  subject  to  the
Company’s  underwriting  standards.  Real  estate  construction
and development loans include commercial construction and
development and residential construction loans. Commercial
construction loans are for small and medium-sized office build-
ings and other commercial properties and residential construc-
tion  loans  are  primarily  for  projects  located  in  upstate  New
York and northeastern Pennsylvania.

Risks associated with the commercial real estate portfolio
include the ability of borrowers to pay interest and principal
during the loan’s term, as well as the ability of the borrowers
to refinance at the end of the loan term.

Funding Sources and Corresponding 
Interest Expense

The Company utilizes traditional deposit products such as
time, savings, NOW, money market, and demand deposits as
its  primary  source  for  funding.  Other  sources,  such  as  short-
term FHLB advances, federal funds purchased, securities sold
under agreements to repurchase, brokered time deposits, and
long-term FHLB borrowings are utilized as necessary to support
the  Company’s  growth  in  assets  and  to  achieve  interest  rate
sensitivity objectives. The average balance of interest-bearing
liabilities increased $330.7 million from 2015, and totaled $5.5
billion  in  2016. The  rate  paid  on  interest-bearing  liabilities
increased from 0.40% in 2015 to 0.41% in 2016. This increase
in rates and increase in average balances, caused an increase
in interest expense of $1.9 million, or 9.2%, from $20.6 million
in 2015 to $22.5 million in 2016.

Deposits

Average interest bearing deposits increased $184.8 million,
or 4.0%, from 2015 to 2016, due primarily to organic deposit
growth. Average money market deposits increased $86.5 mil-
lion or 5.5% during 2016 when compared to 2015. Average
NOW accounts increased $89.9 million or 9.1% during 2016
as compared to 2015. The average balance of savings accounts
increased $63.4 million or 5.9% during 2016 when compared
to 2015. These increases were partially offset by a decrease
in average time deposits, which decreased $55.1 million, or
5.7%,  from  2015  to  2016. The  average  balance  of  demand
deposits increased $188.4 million, or 10.1%, during 2016 when
compared to 2015. This growth in demand deposits was driven
principally  by  increases  in  accounts  from  retail,  municipal,
and commercial customers.

increased from 0.23% in 2015 to 0.46% in 2016. Average long-
term debt decreased from $130.7 million in 2015 to $118.9 mil-

at $101.2 million in 2016. The average rate paid for junior sub-
ordinated debt in 2016 was 2.60%, up from 2.19% in 2015.

erally represent overnight borrowing transactions, and other
short-term borrowings, primarily FHLB advances, with original
maturities of one year or less. The Company has unused lines

of credit and access to brokered deposits available for short-
term  financing  of  approximately  $1.9  billion  and  $2.1  billion

lateralizing  repurchase  agreements  are  held  in  safekeeping
by non-affiliated financial institutions and are under the Com-
pany’s control. Long-term debt, which is comprised primarily
of FHLB advances, are collateralized by the FHLB stock owned
by the Company, certain of its mortgage-backed securities and
a blanket lien on its residential real estate mortgage loans.

Noninterest income for the year ended December 31, 2016
was $115.7 million, down $2.8 million, or 2.3%, from the year
ended December 31, 2015. The decrease was primarily due to
the $4.2 million gain recognized in the third quarter of 2015
from the 2014 sale of Springstone. In addition, net securities
income was down $3.7 million from 2015 due to a $0.6 million
securities loss in 2016 versus a net securities gain for $3.1 million
in 2015. The decreases were offset by increases in retirement
plan administration fees, other noninterest income, ATM and
debit card fees, bank owned life insurance income and insurance
and other financial services revenue. Retirement plan admin-
istration  fees  were  up  $1.9  million,  or  13.6%,  from  2015  due
primarily to the 2015 fourth quarter acquisition of Third Party
Administrators, Inc. and the 2016 third quarter acquisition of
Actuarial Designs & Solutions, Inc. Other noninterest income

was up $1.8 million, or 12.4% primarily due to higher swap fee
income in 2016 than in 2015, an increase in mortgage banking
income and a $0.9 million gain on the sale of equity investments
for  compliance  with  the  Dodd-Frank Wall  Street  Reform  and
Consumer Protection Act in the third quarter of 2016. Nonin-
terest income as a percent of total revenue excluding net secu-
rities (losses) gains and the gain on the sale of equity investment
was 30.6% for the years ended December 31, 2016 and 2015.

Noninterest expense for the year ended December 31, 2016
was $235.9 million, down $0.3 million, or 0.1% from 2015. This
decrease  was  driven  primarily  by  lower  other  noninterest
expense during 2016 than 2015 primarily due to reorganization
expenses incurred during the third quarter of 2015, offset by
higher salaries and employee benefit expenses in 2016. Salaries
and employee benefits expense increased $5.4 million, or 4.3%
from 2015 to 2016, due to higher salaries and medical insurance
costs  that  were  partially  offset  by  lower  pension  credit  and
contract termination costs.

Income Taxes

Income tax expense for the year ended December 31, 2016
was $40.4 million, up from $40.2 million for the same period
in 2015. The effective tax rate was 34.0% for the year ended
December 31, 2016, compared to 34.5% for the same period
in 2015. The decrease in the effective tax rate was due to the

higher  level  of  tax-exempt  income  to  total  income  in  2016
compared to 2015.

We calculate our current and deferred tax provision based
on estimates and assumptions that could differ from the actual
results reflected in income tax returns filed during the subse-
quent year. Adjustments based on filed returns are recorded
when identified, which is generally in the third quarter of the
subsequent year for U.S. federal and state provisions.

The amount of income taxes the Company pays is subject
at times to ongoing audits by federal and state tax authorities,
which may result in proposed assessments. Future results may
include favorable or unfavorable adjustments to the estimated
tax  liabilities  in  the  period  the  assessments  are  proposed  or
resolved or when statutes of limitation on potential assessments
expire. As a result, the Company’s effective tax rate may fluc-
tuate significantly on a quarterly or annual basis.

Risk Management—Credit Risk

Credit risk is managed through a network of loan officers,
credit committees, loan policies, and oversight from the senior
credit officers and Board of Directors. Management follows a
policy of continually identifying, analyzing, and grading credit
risk inherent in each loan portfolio. An ongoing independent

review,  subsequent  to  management’s  review,  of  individual
credits in the commercial loan portfolio is performed by the
independent loan review function. These components of the
Company’s underwriting and monitoring functions are critical
to  the  timely  identification,  classification,  and  resolution  of
problem credits.

acquired loan portfolio. Excluding nonaccrual acquired loans,
originated nonperforming loans to originated loans was 0.61%
at December 31, 2016. The Company recorded a provision for
loan losses of $25.4 million for the year ended December 31,

2016 compared with $18.3 million for the year ended December
31, 2015. Net charge-offs to average loans for the year ended
December 31, 2016 were 0.39%, compared with 0.38% for the
year ended December 31, 2015. The allowance for loan losses
was 160.90% of nonperforming loans at December 31, 2016
as compared to 168.47% at December 31, 2015. The allowance
for  loan  losses  as  a  percentage  of  loans  was  1.05%  (1.13%
excluding acquired loans with no related allowance recorded)
at December 31, 2016, compared to 1.07% (1.18% excluding
acquired loans with no related allowance recorded) at Decem-
ber 31, 2015.

Impaired loans, which primarily consist of nonaccruing com-
mercial, commercial real estate, agricultural, and agricultural
real estate loans, as well as loans that have been modified in a
troubled debt restructuring (“TDR”), increased to $28.9 million
at December 31, 2016 as compared to $27.2 million at December
31, 2015. At December 31, 2016, $7.0 million of the total impaired
loans had a specific reserve allocation of $1.5 million compared
to $5.9 million of impaired loans at December 31, 2015 which
had a specific reserve allocation of $2.0 million.

The allowance for loan losses is maintained at a level esti-
mated by management to provide adequately for risk of prob-
able losses inherent in the current loan portfolio. The adequacy
of the allowance for loan losses is continuously monitored. It
is  assessed  for  adequacy  using  a  methodology  designed  to
ensure the level of the allowance reasonably reflects the loan
portfolio’s risk profile. It is evaluated to ensure that it is sufficient
to absorb all reasonably estimable credit losses inherent in the
current loan portfolio.

Management  considers  the  accounting  policy  relating  to
the allowance for loan losses to be a critical accounting policy
given the inherent uncertainty in evaluating the levels of the
allowance required to cover credit losses in the portfolio and
the material effect that such judgments can have on the con-
solidated results of operations.

For purposes of evaluating the adequacy of the allowance,
the Company considers a number of significant factors that affect
the collectability of the portfolio. For individually analyzed loans,
these include estimates of loss exposure, which reflect the facts
and circumstances that affect the likelihood of repayment of

such loans as of the evaluation date. For homogeneous pools
of loans, estimates of the Company’s exposure to credit loss
reflect a current assessment of a number of factors, which could
affect collectability. These factors include: past loss experience;
size, trend, composition, and nature of loans; changes in lending
policies and procedures, including underwriting standards and
collection, charge-offs and recoveries; trends experienced in
nonperforming and delinquent loans; current economic condi-
tions in the Company’s market; portfolio concentrations that
may affect loss experienced across one or more components of
the portfolio; the effect of external factors such as competition,
legal and regulatory requirements; and the experience, ability,
and depth of lending management and staff. In addition, various
regulatory agencies, as an integral component of their exami-
nation 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 examinations.

After  a  thorough  consideration  of  the  factors  discussed
above, any required additions to the allowance for loan losses
are  made  periodically  by  charges  to  the  provision  for  loan
losses. These charges are necessary to maintain the allowance
at a level which management believes is reasonably reflective
of overall inherent risk of probable loss in the portfolio. While
management  uses  available  information  to  recognize  losses
on loans, additions to the allowance may fluctuate from one
reporting period to another. These fluctuations are reflective
of  changes  in  risk  associated  with  portfolio  content  and/or
changes in management’s assessment of any or all of the deter-
mining factors discussed above.

In  addition  to  the  nonperforming  loans  discussed  above,
the Company has also identified approximately $70.0 million
in potential problem loans at December 31, 2016 as compared
to $73.8 million at December 31, 2015. Potential problem loans
are  loans  that  are  currently  performing,  with  a  possibility  of
loss if weaknesses are not corrected. Such loans may need to
be  disclosed  as  nonperforming  at  some  time  in  the  future.
Potential problem loans are classified by the Company’s loan
rating system as “substandard.” At December 31, 2016, there
were 17 potential problem loans exceeding $1.0 million, totaling
$34.9 million in aggregate, compared to 13 potential problem

loans exceeding $1.0 million, totaling $25.0 million at December
31, 2015. Management cannot predict the extent to which eco-
nomic  conditions  may  worsen  or  other  factors  which  may
impact borrowers and the potential problem loans. Accordingly,
there  can  be  no  assurance  that  other  loans  will  not  become
90 days or more past due, be placed on nonaccrual, become
restructured, or require increased allowance coverage and pro-
vision for loan losses. To mitigate this risk, the Company main-
tains a diversified loan portfolio, has no significant concentration
in any particular industry, and originates loans primarily within
its footprint.

The following table sets forth the allocation of the allowance
for loan losses by category, as well as the percentage of loans
in each category to total loans, as prepared by the Company.
This allocation is based on management’s assessment of the
risk characteristics of each of the component parts of the total
loan  portfolio  as  of  a  given  point  in  time  and  is  subject  to
changes as and when the risk factors of each such component

part change. The allocation is not indicative of either the specific
amounts  of  the  loan  categories  in  which  future  charge-offs
may be taken, nor should it be taken as an indicator of future

does not restrict the use of the allowance to absorb losses in
any category.

The Company’s accounting policy relating to the allowance
for loan losses requires a review of each significant loan type
within the loan portfolio, considering asset quality trends for
each type, including, but not limited to, delinquencies, nonac-
cruals, historical charge-off experience, and specific economic
factors (e.g. milk prices are considered when reviewing agri-
cultural loans). Based on this review, management believes the
reserve allocations are adequate to address any trends in asset
quality indicators. As a result of the general improvement and
stabilization of asset quality indicators in 2016, as well as the
aforementioned review of the loan portfolio, the allowance for
loan losses as a percentage of originated loans decreased from
1.18% as of December 31, 2015 to 1.13% as of December 31,
2016. Acquired loans were recorded at fair value on the date
of acquisition, with no carryover of the related allowance for
loan losses. Generally, the fair value discount represents expected
credit losses, net of market interest rate adjustments. The dis-
count on loans receivable will be amortized to interest income
over the estimated remaining life of the acquired loans using
the level yield method.

At December 31, 2015, approximately 59% of the Company’s
loans were secured by real estate located in central and northern
New York, northeastern Pennsylvania, western Massachusetts,
southern  New  Hampshire, Vermont,  and  Maine.  Accordingly,
the ultimate collectability of a substantial portion of the Com-
pany’s portfolio is susceptible to changes in market conditions
of those areas. Management is not aware of any material con-
centrations of credit to any industry or individual borrowers.

Subprime  mortgage  lending,  which  has  been  the  riskiest
sector of the residential housing market, is not a market that
the Company has ever actively pursued. The market does not
apply a uniform definition of what constitutes “subprime” lending.
Our reference to subprime lending relies upon the “Statement
on  Subprime  Mortgage  Lending”  issued  by  the  OTS  and  the
other federal bank regulatory agencies (the “Agencies”), on June
29, 2007, which further referenced the “Expanded Guidance for
Subprime Lending Programs,” or the Expanded Guidance, issued
by the Agencies by press release dated January 31, 2001. In the
Expanded Guidance, the Agencies indicated that subprime lend-
ing does not refer to individual subprime loans originated and
managed, in the ordinary course of business, as exceptions to
prime  risk  selection  standards. The  Agencies  recognize  that
many  prime  loan  portfolios  will  contain  such  accounts. The
Agencies also excluded prime loans that develop credit problems
after acquisition and community development loans from the
subprime arena. According to the Expanded Guidance, subprime
loans are other loans to borrowers which display one or more
characteristics of reduced payment capacity. Five specific criteria,
which are not intended to be exhaustive and are not meant to
define specific parameters for all subprime borrowers and may
not match all markets or institutions’ specific subprime definitions,
are  set  forth,  including  having  a  FICO  score  of  660  or  below.
Based upon the definition and exclusions described above, the
Company is a prime lender. Within the loan portfolio, there are
loans that, at the time of origination, had FICO scores of 660 or
below.  However,  since  the  Company  is  a  portfolio  lender,  it

40

NBT BANCORP 2016 FORM 10-K

reviews all data contained in borrower credit reports and does
not base underwriting decisions solely on FICO scores. We believe
the aforementioned loans, when made, were amply collateralized
and otherwise conformed to our prime lending standards.

For acquired loans that are not deemed to be impaired at
acquisition, credit discounts representing the principal losses
expected over the life of the loan are a component of the initial
fair value and amortized over the life of the asset.

As a result of the application of this accounting methodology,
certain  credit-related  ratios  may  not  necessarily  be  directly
comparable with periods prior to acquisitions, or comparable
with other institutions. The credit metrics most impacted by
our acquisition of loans related to the acquisition of Alliance
Financial Corporation (“Alliance”) were the allowance for loans
losses to total loans, and total allowance for loan losses to non-
performing loans. As of December 31, 2016, the allowance for
loan  losses  to  total  originated  loans  and  the  total  allowance
for loan losses to originated nonperforming loans were 1.13%
and 186.82%, respectively.

Liquidity Risk

Liquidity involves the ability to meet the cash flow require-
ments of customers who may be depositors wanting to with-
draw  funds  or  borrowers  needing  assurance  that  sufficient
funds  will  be  available  to  meet  their  credit  needs. The  Asset
Liability Committee (ALCO) is responsible for liquidity manage-
ment and has developed guidelines which cover all assets and
liabilities, as well as off-balance sheet items that are potential
sources or uses of liquidity. Liquidity policies must also provide
the flexibility to implement appropriate strategies. Requirements
change as loans grow, deposits and securities mature, and pay-
ments on borrowings are made. Liquidity management includes
a focus on interest rate sensitivity management with a goal of
avoiding widely fluctuating net interest margins through periods
of changing economic conditions.

The primary liquidity measurement the Company utilizes is
called “Basic Surplus,” which captures the adequacy of its access
to reliable sources of cash relative to the stability of its funding
mix of average liabilities. This approach recognizes the impor-
tance of balancing levels of cash flow liquidity from short and
long-term securities with the availability of dependable bor-
rowing  sources  which  can  be  accessed  when  necessary.  At
December 31, 2016, the Company’s Basic Surplus measurement
was 13.6% of total assets, or $1.2 billion, which was above the
Company’s  minimum  of  5%  (calculated  at  $443.4  million  of
period end total assets at December 31, 2016) set forth in its
liquidity policies.

This Basic Surplus approach enables the Company to ade-
quately manage liquidity from both operational and contin-
gency  perspectives.  By  tempering  the  need  for  cash  flow
liquidity with reliable borrowing facilities, the Company is able
to operate with a more fully invested and, therefore, higher
interest income generating securities portfolio. The makeup
and term structure of the securities portfolio is, in part, impacted
by  the  overall  interest  rate  sensitivity  of  the  balance  sheet.
Investment  decisions  and  deposit  pricing  strategies  are
impacted by the liquidity position. At December 31, 2016, the
Company considered its Basic Surplus position to be strong.
However, certain events may adversely impact the Company’s
liquidity position in 2017. Improvement in the economy may
increase  competitive  pressure  on  deposit  pricing,  which,  in
turn, could result in a decrease in the Company’s deposit base
or  increase  funding  costs.  Additionally,  liquidity  will  come
under  additional  pressure  if  loan  growth  exceeds  deposit
growth in 2017. These scenarios could lead to a decrease in
the  Company’s  Basic  Surplus  measure  below  the  minimum
policy level of 5%. To manage this risk, the Company has the
ability  to  purchase  brokered  time  deposits,  borrow  against
established  borrowing  facilities  with  other  banks  (Federal
funds), and enter into repurchase agreements with investment
companies. The additional liquidity that could be provided by
these measures was $1.6 billion at December 31, 2016. In addi-
tion, the Bank has enhanced its “Borrower-in-Custody” program
with the FRB with the addition of the ability to pledge auto-
mobile loans. At December 31, 2016, the Bank had the capacity
to borrow $832 million from this program.

At December 31, 2016 and 2015, FHLB advances outstanding
totaled $598 million and $432 million, respectively. The Bank
is a member of the FHLB system and had additional borrowing
capacity from the FHLB of approximately $0.8 billion at Decem-
ber 31, 2016 and $1.1 billion at December 31, 2015. In addition,
unpledged  securities  could  have  been  used  to  increase  bor-
rowing capacity at the FHLB by an additional $706 million at
December 31, 2016 or used to collateralize other borrowings,
such as repurchase agreements.

At  December  31,  2016,  a  portion  of  the  Company’s  loans
and securities were pledged as collateral on borrowings. There-
fore,  future  growth  of  earning  assets  will  depend  upon  the
Company’s ability to obtain additional funding, through growth
of core deposits and collateral management, and may require
further  use  of  brokered  time  deposits,  or  other  higher  cost
borrowing arrangements.

Net  cash  flows  provided  by  operating  activities  totaled
$113.5 million in 2016 and $124.5 million in 2015. The critical
elements  of  net  operating  cash  flows  include  net  income,
adjusted for non-cash income and expense items such as the
provision for loan losses, deferred income tax expense, depre-
ciation and amortization, and cash flows generated through
changes in other assets and liabilities.

Net cash flows used by investing activities totaled $633.9
million and $504.0 million in 2016 and 2015, respectively. Critical
elements of investing activities are loan and investment secu-
rities transactions.

Net  cash  flows  provided  by  financing  activities  totaled
$529.3 million in 2016 as compared to $373.1 million in 2015.

The critical elements of financing activities are proceeds from
deposits, borrowings, and stock issuances. In addition, financ-
ing activities are impacted by dividends and treasury stock
transactions.

Contractual Obligations

In  connection  with  its  financing  and  operating  activities,
the Company has entered into certain contractual obligations.
The  Company’s  future  minimum  cash  payments,  excluding
interest, associated with its contractual obligations pursuant
to its borrowing agreements, operating leases, and other obli-
gations at December 31, 2016 are as follows:

                                                                                                                                                                  Payments Due by Period

We  have  obligations  under  our  pension,  post-retirement
plan, directors’ retirement and supplemental executive retire-
ment plans as described in Note 13 to the consolidated financial
statements. The supplemental executive retirement, pension
and postretirement benefit and directors’ retirement payments
represent actuarially determined future benefit payments to
eligible plan participants.

Commitments to Extend Credit

The Company makes contractual commitments to extend
credit, which include unused lines of credit, which are subject
to the Company’s credit approval and monitoring procedures.
At December 31, 2016 and 2015, commitments to extend credit
in the form of loans, including unused lines of credit, amounted
to $1.5 billion and $1.3 billion, respectively. In the opinion of
management, there are no material commitments to extend
credit, including unused lines of credit that represent unusual
risks. All commitments to extend credit in the form of loans,
including unused lines of credit, expire within one year.

Standby Letters of Credit

The  Company  does  not  issue  any  guarantees  that  would
require liability-recognition or disclosure, other than its standby
letters of credit. The Company guarantees the obligations or

performance of customers by issuing standby letters of credit
to third parties. These standby letters of credit are frequently
issued in support of third party debt, such as corporate debt
issuances, industrial revenue bonds, and municipal securities.
The risk involved in issuing standby letters of credit is essentially
the same as the credit risk involved in extending loan facilities
to customers, and they are subject to the same credit origination,
portfolio maintenance and management procedures in effect
to monitor other credit and off-balance sheet products. Typically,
these instruments have terms of five years or less and expire
unused; therefore, the total amounts do not necessarily repre-
sent future cash requirements. At December 31, 2016 and 2015,
outstanding standby letters of credit were approximately $36.8
million  and  $31.5  million,  respectively. The  fair  value  of  the
Company’s standby letters of credit at December 31, 2016 and
2015  was  not  significant. The  following  table  sets  forth  the
commitment expiration period for standby letters of credit at
December 31, 2016:

Within one year                                                                                 $27,664
After one but within three years                                                       4,593
After three but within five years                                                       3,657
After five years                                                                                           901

Interest Rate Swaps

The Company records all derivatives on the balance sheet
at fair value. The accounting for changes in the fair value of
derivatives  depends  on  the  intended  use  of  the  derivative,
whether the Company has elected to designate a derivative
in  a  hedging  relationship  and  apply  hedge  accounting  and
whether  the  hedging  relationship  has  satisfied  the  criteria
necessary to apply hedge accounting. Derivatives designated
and qualifying as a hedge of the exposure to changes in the
fair value of an asset, liability, or firm commitment attributable
to a particular risk, such as interest rate risk, are considered
fair value hedges. Derivatives designated and qualifying as a
hedge of the exposure to variability in expected future cash
flows, or other types of forecasted transactions, are considered
cash  flow  hedges.  Hedge  accounting  generally  provides  for
the matching of the timing of gain or loss recognition on the
hedging  instrument  with  the  recognition  of  the  changes  in
the fair value of the hedged asset or liability that are attributable
to the hedged risk in a fair value hedge or the earnings effect
of the hedged forecasted transactions in a cash flow hedge.
The  Company  may  enter  into  derivative  contracts  that  are
intended to economically hedge certain of its risk, even though
hedge accounting does not apply or the Company elects not
to apply hedge accounting.

For derivatives designated as fair value hedges, changes in
the fair value of the derivative and the hedged item related to
the hedged risk are recognized in earnings. Any hedge inef-
fectiveness would be recognized in the income statement line
item pertaining to the hedged item. For derivatives designated
as  cash  flow  hedges,  changes  in  fair  value  of  the  effective
portion of the cash flow hedges are reported in OCI. When the
cash flows associated with the hedged item are realized, the
gain or loss included in OCI is recognized in the Consolidated
Statement of Income.

When the Company purchases a portion of a commercial
loan  that  has  an  existing  interest  rate  swap,  it  enters  a  risk
participation agreement with the counterparty and assumes
the credit risk of the loan customer related to the swap. Any
fee paid to the Company under a risk participation agreement
is in consideration of the credit risk of the counterparties and
is recognized in the income statement. Credit risk on the risk
participation agreements is determined after considering the
risk  rating,  probability  of  default  and  loss  given  default  of
the counterparties.

Loans Serviced for Others and 
Loans Sold with Recourse

The  total  amount  of  loans  serviced  by  the  Company  for
unrelated third parties was approximately $604.0 million and
$616.1 million at December 31, 2016 and 2015, respectively.
At December 31, 2016 and 2015, the Company had approxi-
mately $0.9 million and $1.1 million, respectively, of mortgage
servicing rights. At December 31, 2016 and 2015, the Company
serviced $28.5 million and $25.1 million, respectively, of agri-
cultural  loans  sold  with  recourse.  Due  to  sufficient  collateral
on these loans, no reserve is considered necessary at December
31,  2016  and  2015.  As  of  December  31,  2016  and  2015,  the
Company serviced $72.2 million and $47.3 million, respectively,
of consumer loans serviced for Springstone.

Capital Resources

Consistent with its goal to operate a sound and profitable
financial institution, the Company actively seeks to maintain a
“well-capitalized”  institution  in  accordance  with  regulatory
standards. The  principal  source  of  capital  to  the  Company  is
earnings retention. The Company’s capital measurements are
in  excess  of  both  regulatory  minimum  guidelines  and  meet
the requirements to be considered well-capitalized.

The Company’s principal source of funds to pay interest on
trust preferred debentures and pay cash dividends to its share-
holders  are  dividends  from  its  subsidiaries. Various  laws  and
regulations  restrict  the  ability  of  banks  to  pay  dividends  to
their shareholders. Generally, the payment of dividends by the
Company in the future as well as the payment of interest on
the capital securities will require the generation of sufficient
future earnings by its subsidiaries.

The Bank also is subject to substantial regulatory restrictions
on its ability to pay dividends to the Company. Under OCC reg-
ulations, the Bank may not pay a dividend, without prior OCC
approval, if the total amount of all dividends declared during
the calendar year, including the proposed dividend, exceeds
the sum of its retained net income to date during the calendar
year and its retained net income over the preceding two years.
At  December  31,  2016,  approximately  $102.5  million  of  the
total stockholders’ equity of the Bank was available for payment
of  dividends  to  the  Company  without  approval  by  the  OCC.
The Bank’s ability to pay dividends also is subject to the Bank
being in compliance with regulatory capital requirements. The
Bank is currently in compliance with these requirements.

Stock Repurchase Plan

The  Company  purchased  675,535  shares  of  its  common
stock during the year ended December 31, 2016 at an average
price of $25.45 per share under a previously announced plan
that expired on December 31, 2016. As of December 31, 2016,
there were 1,000,000 shares available for repurchase under the
repurchase plan that was announced on March 28, 2016, which
expires on December 31, 2017.

Recent Accounting Updates

See Note 24 to the consolidated financial statements for a

detailed discussion of new accounting pronouncements.

2015 OPERATING RESULTS AS COMPARED 
TO 2014 OPERATING RESULTS

Net Interest Income

Net interest income was $252.6 million for the year ended
December 31, 2015, up $0.7 million from 2014. FTE net interest
margin was 3.50% for the year ended December 31, 2015, down
from 3.61% for the year ended December 31, 2014. Average
interest earning assets were up $241.8 million, or 3.4%, for the
year  ended  December  31,  2015  as  compared  to  2014. This
increase  from  last  year  was  driven  primarily  by  organic  loan
growth. Yields on earning assets decreased from 3.94% during
2014  to  3.78%  for  2015,  more  than  offsetting  the  growth  in
earning assets, resulting in a 0.7% decrease in interest income
for the year ended December 31, 2015 as compared to the year
ended December 31, 2014. The yield compression was driven
by a 20 basis-point decrease in loan yields from 2014 to 2015.
Average interest bearing liabilities increased $21.0 million, or
0.4%,  from  the  year  ended  December  31,  2014  to  the  year
ended  December  31,  2015. Total  average  deposits  increased
$344.2 million, or 5.6%, for the year ended December 31, 2015
as compared to last year driven primarily by an 11.2% increase
in noninterest bearing demand deposits, as well as increases
in  money  market  deposit  accounts  and  savings  deposits  in
2015. This increase was partially offset by a decrease in average
long-term  borrowings  of  $93.9  million  for  the  year  ended
December 31, 2015 as compared to last year due to the debt
restructuring completed during the third quarter of 2014, which
resulted in the prepayment of $165.0 million of long-term debt.
In  addition,  average  short-term  borrowings  decreased  $42.6

million for the year ended December 31, 2015 as compared to
last year driven by deposit growth. The rates paid on interest
bearing liabilities decreased by 5 basis-points for the year ended
December 31, 2015 as compared to 2014. This decrease resulted
primarily from a shift in deposits into lower cost core deposits
as well as the aforementioned debt restructuring.

Loans and Corresponding Interest 
and Fees on Loans

The average balance of loans increased by approximately
$215.8 million, or 3.9%, from 2014 to 2015. The yield on average
loans decreased from 4.42% in 2014 to 4.22% in 2015, as loan
rates declined due to the continued low rate environment in
2015. Interest income from loans decreased 0.6%, from $244.2
million  in  2014  to  $242.6  million  in  2015. This  decrease  was
due to the decrease in yields, partially offset by the increase in
average loan balances.

Total loans increased $287.9 million, or 5.1%, from December
31,  2014  to  December  31,  2015.  Increases  in  residential  real
estate mortgages, commercial real estate loans, and consumer
loans  were  the  primary  drivers  of  the  increase  in  total  loans
from 2014 as the Company experienced strong originations in
2015 in the upstate New York and Vermont markets.

Securities and Corresponding Interest 
and Dividend Income

The average balance of AFS securities decreased $199.7 mil-
lion,  or  15.9%,  from  2014  to  2015. The  yield  on  average  AFS
securities was 1.97% for 2015 compared to 2.05% in 2014.

The average balance of HTM securities increased from $233.5
million in 2014 to $459.6 million in 2015. At December 31, 2015,
HTM securities were comprised primarily of tax-exempt munic-
ipal  securities. The  yield  on  HTM  securities  decreased  from
2.81% in 2014 to 2.46% in 2015.

During the third quarter of 2014, the Company transferred
$340.5 million in securities from the AFS portfolio to the HTM
portfolio  to  mitigate  the  impact  of  volatility  of  interest  rate
changes on tangible book value.

The average balance of FRB and FHLB stock decreased to
$33.0 million in 2015 from $39.3 million in 2014. The yield from
investments in FRB and FHLB banks increased from 5.10% in
2014 to 5.18% in 2015.

Funding Sources and Corresponding 
Interest Expense

The Company utilizes traditional deposit products such as
time, savings, NOW, money market, and demand deposits as
its  primary  source  for  funding.  Other  sources,  such  as  short-
term FHLB advances, federal funds purchased, securities sold
under agreements to repurchase, brokered time deposits, and
long-term FHLB borrowings are utilized as necessary to support
the  Company’s  growth  in  assets  and  to  achieve  interest  rate
sensitivity objectives. The average balance of interest-bearing
liabilities increased $21.0 million from 2014, and totaled $5.2
billion  in  2015. The  rate  paid  on  interest-bearing  liabilities
decreased from 0.45% in 2014 to 0.40% in 2015. This decrease
in  rates,  partially  offset  by  an  increase  in  average  balances,
caused a decrease in interest expense of $2.6 million, or 11.1%,
from $23.2 million in 2014 to $20.6 million in 2015.

Deposits

Average interest bearing deposits increased $157.4 million,
or 3.5%, from 2014 to 2015, due primarily to organic deposit
growth.  Average  money  market  deposits  increased  $124.3
million or 8.5% during 2015 when compared to 2014. Average
NOW accounts increased $37.9 million or 4.0% during 2015
as compared to 2014. The average balance of savings accounts
increased $50.8 million or 5.0% during 2015 when compared
to 2014. These increases were partially offset by a decrease
in average time deposits, which decreased $55.6 million, or
5.5%,  from  2014  to  2015. The  average  balance  of  demand
deposits increased $186.8 million, or 11.2%, during 2015 when
compared to 2014. This growth in demand deposits was driven
principally  by  increases  in  accounts  from  retail,  municipal,
and commercial customers.

The  rate  paid  on  average  interest-bearing  deposits  was
0.31%  for  2015  and  2014. The  rate  paid  for  money  market
deposit accounts increased from 0.17% during 2014 to 0.21%
during  2015. The  rate  paid  for  time  deposits  increased  from
0.97% during 2014 to 1.01% during 2015. The rate paid for sav-
ings  deposits  decreased  from  0.07%  during  2014  to  0.06%
during 2015.

Borrowings

Average short-term borrowings decreased to $339.9 million
in 2015 from $382.5 million in 2014. The average rate paid on
short-term borrowings increased from 0.22% in 2014 to 0.23%
in 2015. Average long-term debt decreased from $224.6 million
in 2014 to $130.7 million in 2015. This decrease was due to the

long-term debt restructure completed in the third quarter of
2014  which  resulted  in  the  prepayment  of  $165.0  million  of
long-term debt.

The average balance of junior subordinated debt remained
at  $101.2  million  in  2015. The  average  rate  paid  for  junior
subordinated debt in 2015 was 2.19%, up slightly from 2.14%
in 2014.

Short-term borrowings consist of Federal funds purchased
and securities sold under repurchase agreements, which gen-
erally represent overnight borrowing transactions, and other
short-term borrowings, primarily FHLB advances, with original
maturities of one year or less. The Company has unused lines
of credit and access to brokered deposits available for short-
term  financing  of  approximately  $2.0  billion  and  $1.8  billion
at  December  31,  2015  and  2014,  respectively.  Securities  col-
lateralizing repurchase agreements are held in safekeeping by
non-affiliated financial institutions and are under the Company’s
control. Long-term debt, which is comprised primarily of FHLB
advances, are collateralized by the FHLB stock owned by the
Company, certain of its mortgage-backed securities and a blan-
ket lien on its residential real estate mortgage loans.

Noninterest income for the year ended December 31, 2015
was $118.5 million, down $7.5 million, or 6.0%, from the year
ended December 31, 2014. The decrease from 2014 was pri-
marily driven by a $19.4 million gain recognized in 2014 from
the  previously  disclosed  sale  of  our  ownership  interest  in
Springstone as compared with the $4.2 million gain recognized
in 2015. Excluding the gains recognized from the sale of equity
investments, noninterest income was up $7.7 million, or 7.2%,
from 2014 to 2015. This increase was driven in part to a gain
on  the  sale  of  an  equity  investment  totaling  $3.0  million  in
the fourth quarter of 2015. In addition, retirement plan admin-
istration  fees  were  up  $2.0  million,  or  16.6%,  from  2014  to
2015  due  to  new  business  generation  as  well  as  the  2015
acquisition of Third Party Administrators, Inc.. ATM and debit
card fees were up $1.1 million, or 6.5%, in 2015 as compared
to 2014 due to an increase in debit card activity. Other nonin-
terest income was up $3.7 million in 2015 as compared with
2014 due primarily to charge-off recoveries on acquired loans
of $1.5 million and a favorable settlement of a prior accrual of
$1.6 million in 2015.

Noninterest Expense

Noninterest expense for the year ended December 31, 2015
was $236.2 million, down $9.9 million from 2014. This decrease
was driven primarily by $17.9 million in prepayment penalties

resulting from the debt restructuring in 2014. Excluding these
prepayment penalties, noninterest expense was up $8.0 million,
or 3.5%, from 2014 to 2015. This increase was due primarily to
an increase in salaries and employee benefits of $4.7 million,
or 3.9%, from 2014 to 2015. This increase was driven primarily
by a $2.4 million increase in post-retirement expenses as well
as contract termination costs totaling $1.6 million accrued in
the fourth quarter of 2015. In addition, other operating expenses
were  up  $4.6  million  in  2015  as  compared  with  2014. This
increase was driven primarily by branch reorganization expenses
totaling $3.8 million in 2015.

Income Taxes

Income tax expense for the year ended December 31, 2015
was $40.2 million, up from $37.2 million for the same period
in 2014. The effective tax rate was 34.5% for the year ended
December 31, 2015, compared to 33.2% for the same period
in 2014.

The income tax expense on the Company’s income was dif-
ferent  than  the  income  tax  expense  at  the  Federal  statutory
rate of 35% due primarily to tax exempt income and, to a lesser
extent, the effect of state income taxes and Federal low income
housing tax credits.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Interest rate risk is the most significant market risk affecting
the Company. Other types of market risk, such as foreign cur-
rency exchange rate risk and commodity price risk, do not arise
in the normal course of the Company’s business activities or
are immaterial to the results of operations.

Interest rate risk is defined as an exposure to a movement
in interest rates that could have an adverse effect on the Com-
pany’s net interest income. Net interest income is susceptible
to interest rate risk to the degree that interest-bearing liabilities
mature or reprice on a different basis than earning assets. When
interest-bearing liabilities mature or reprice more quickly than
earning assets in a given period, a significant increase in market
rates  of  interest  could  adversely  affect  net  interest  income.
Similarly, when earning assets mature or reprice more quickly
than interest-bearing liabilities, falling interest rates could result
in a decrease in net interest income.

In an attempt to manage the Company’s exposure to changes
in interest rates, management monitors the Company’s interest
rate  risk.  Management’s  asset/liability  committee  (“ALCO”)
meets monthly to review the Company’s interest rate risk posi-
tion and profitability, and to recommend strategies for consid-
eration by the Board of Directors. Management also reviews
loan and deposit pricing, and the Company’s securities portfolio,
formulates  investment  and  funding  strategies,  and  oversees
the timing and implementation of transactions to assure attain-
ment of the Board’s objectives in the most effective manner.
Notwithstanding the Company’s interest rate risk management
activities, the potential for changing interest rates is an uncer-
tainty that can have an adverse effect on net income.

In adjusting the Company’s asset/liability position, the Board
and management attempt to manage the Company’s interest
rate risk while minimizing the net interest margin compression.
At times, depending on the level of general interest rates, the
relationship between long and short-term interest rates, market
conditions and competitive factors, the Board and management
may  determine  to  increase  the  Company’s  interest  rate  risk
position somewhat in order to increase its net interest margin.
The Company’s results of operations and net portfolio values
remain vulnerable to changes in interest rates and fluctuations
in the difference between long and short-term interest rates.

The primary tool utilized by ALCO to manage interest rate
risk is through earnings at risk modeling (interest rate sensitivity
analysis).  Information  such  as  principal  balance,  interest  rate,
maturity date, cash flows, next repricing date (if needed), and
current rates is uploaded into the model to create an ending
balance  sheet.  In  addition,  ALCO  makes  certain  assumptions
regarding prepayment speeds for loans and mortgage related
investment  securities  along  with  any  optionality  within  the
deposits and borrowings. The model is first run under an assump-
tion  of  a  flat  rate  scenario  (i.e.  no  change  in  current  interest
rates)  with  a  static  balance  sheet. Two  additional  models  are
run in which a gradual increase of 200 bps and a gradual decrease
of 100 bps takes place over a 12 month period with a static bal-
ance sheet. Under these scenarios, assets subject to prepayments
are adjusted to account for faster or slower prepayment assump-
tions. Any investment securities or borrowings that have callable
options embedded into them are handled accordingly based
on the interest rate scenario. The resultant changes in net interest
income are then measured against the flat rate scenario.

46

In the declining rate scenario, net interest income is projected
to decrease slightly when compared to the forecasted net inter-
est  income  in  the  flat  rate  scenario  through  the  simulation
period. The decrease in net interest income is a result of earning
assets repricing downward, given potential higher prepayments
and lower reinvestment rates, slightly faster than the interest
bearing liabilities that are at or near their floors. In the rising
rate scenarios, net interest income is projected to experience
a  decline  from  the  flat  rate  scenario;  however,  the  potential
impact on earnings is dependent on the ability to lag deposit
repricing on NOW, savings, MMDA, and CD accounts. Net interest
income for the next twelve months in the +200/–100 bp sce-
narios,  as  described  above,  is  within  the  internal  policy  risk
limits of not more than a 7.5% change in net interest income.
The following table summarizes the percentage change in net
interest income in the rising and declining rate scenarios over
a 12-month period from the forecasted net interest income in
the  flat  rate  scenario  using  the  December  31,  2016  balance
sheet position:

The Company anticipates that under the current low rate
environment, on a monthly basis, interest income is expected
to  decrease  at  a  faster  rate  than  interest  expense  given  the
potential  higher  prepayments  and  reinvestment  into  lower
rates as deposit rates are at or near their respective floors. In
order  to  protect  net  interest  income  from  anticipated  net
interest margin compression in 2017, the Company will continue
to focus on increasing earning assets while maintaining a bal-
anced asset mix of loans and investments, and focus on funding
growth through lower cost core deposits.

Another tool used by ALCO to manage interest rate risk is
financial modeling of net portfolio values (discounted present
value of assets minus discounted present value of liabilities).
The table below represents the percent change in net portfolio
values from base case (flat rates) for +200/–100 instantaneous
rate shocks:

NBT Bancorp Inc. and Subsidiaries:

Notes to Consolidated Financial Statements
December 31, 2016 and 2015

(1)  Summary of Significant Accounting Policies

The accounting and reporting policies of NBT Bancorp Inc.
(“NBT Bancorp”) and its subsidiaries, NBT Bank, National Asso-
ciation (“NBT Bank” or the “Bank”), NBT Holdings, Inc., and NBT
Financial Services, Inc., conform, in all material respects, with
accounting principles generally accepted in the United States
of America (“GAAP”) and to general practices within the banking
industry.  Collectively,  NBT  Bancorp  and  its  subsidiaries  are
referred to herein as “the Company.”

The preparation of financial statements in conformity with
GAAP requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the
financial  statements  and  the  reported  amounts  of  revenues
and expenses during the reporting period. Actual results could
differ from these estimates.

Estimates  associated  with  the  allowance  for  loan  losses,
income taxes, pension expense, fair values of financial instru-
ments,  status  of  contingencies  and  other-than-temporary
impairment (“OTTI”) on investments are particularly susceptible
to material change in the near term.

The  following  is  a  description  of  significant  policies  and

practices:

Consolidation

The accompanying consolidated financial statements include
the accounts of NBT Bancorp and its wholly-owned subsidiaries
mentioned above. All material intercompany transactions have
been eliminated in consolidation. Amounts previously reported
in the consolidated financial statements are reclassified whenever
necessary to conform to the current year’s presentation. In the
“Parent Company Financial Information,” the investment in sub-
sidiaries is recorded using the equity method of accounting.

The Company determines whether it has a controlling finan-
cial interest in an entity by first evaluating whether the entity
is  a  voting  interest  entity  or  a  variable  interest  entity  under
GAAP. Voting  interest  entities  are  entities  in  which  the  total
equity investment at risk is sufficient to enable the entity to
finance itself independently and provides the equity holders
with the obligation to absorb losses, the right to receive residual
returns  and  the  right  to  make  decisions  about  the  entity’s
activities. The Company consolidates voting interest entities
in which it has all, or at least a majority of, the voting interest.

As defined in applicable accounting standards, variable interest
entities (“VIEs”) are entities that lack one or more of the char-
acteristics  of  a  voting  interest  entity.  A  controlling  financial
interest in a VIE is present when the Company has both the
power and ability to direct the activities of the VIE that most
significantly impact the VIE’s economic performance and an
obligation  to  absorb  losses  or  the  right  to  receive  benefits
that could potentially be significant to the VIE. The Company’s
wholly-owned subsidiaries CNBF Capital Trust I, NBT Statutory
Trust I, NBT Statutory Trust II, Alliance Financial Capital Trust I
and  Alliance  Financial  Capital Trust  II  are VIEs  for  which  the
Company  is  not  the  primary  beneficiary.  Accordingly,  the
accounts of these entities are not included in the Company’s
consolidated financial statements.

Segment Reporting

The Company’s operations are primarily in the community
banking industry and include the provision of traditional banking
services. The  Company  also  provides  other  services  through
its subsidiaries such as insurance, retirement plan administration,
and trust administration. The Company operates solely in the
geographical regions of central and upstate New York, north-
eastern  Pennsylvania,  western  Massachusetts,  southern  New
Hampshire, Vermont, and the greater Portland, Maine area. The
Company has no reportable operating segments.

Cash Equivalents

The Company considers amounts due from correspondent
banks,  cash  items  in  process  of  collection,  and  institutional
money market mutual funds to be cash equivalents for purposes
of the consolidated statements of cash flows.

Securities

The Company classifies its securities at date of purchase as
either held to maturity (“HTM”), trading or available for sale
(“AFS”). HTM debt securities are those that the Company has
the ability and intent to hold until maturity. Trading securities
are securities purchased with the intent to sell within a short
period of time. AFS securities are securities that are not classified
as a HTM or trading securities. AFS securities are recorded at
fair  value.  Unrealized  holding  gains  and  losses,  net  of  the

54

related tax effect, on AFS securities are excluded from earnings
and are reported in the consolidated statements of stockhold-
ers’ equity and the consolidated statements of comprehensive
income as a component of accumulated other comprehensive
income or loss. HTM securities are recorded at amortized cost.
Trading securities are recorded at fair value, with net unrealized
gains and losses recognized in income. Transfers of securities
between categories are recorded at fair value at the date of
transfer. Declines in the fair value of HTM and AFS securities
below their cost that are deemed to be other than temporary
are  reflected  in  earnings  as  realized  losses  or  in  other  com-
prehensive  income,  depending  on  whether  the  Company
intends  to  sell  the  security  or  more  likely  than  not  will  be
required to sell the security before recovery of its amortized
cost basis less any current-period credit loss. If the Company
intends  to  sell  the  security  or  more  likely  than  not  will  be
required to sell the security before recovery of its amortized
cost basis less any current-period credit loss, the OTTI shall be
recognized in earnings equal to the entire difference between
the investment’s amortized cost basis and its fair value at the
balance  sheet  date.  If  the  Company  does  not  intend  to  sell
the security and it is not more likely than not that the entity
will be required to sell the security before recovery of its amor-
tized  cost  basis  less  any  current-period  credit  loss,  the  OTTI
shall be separated into (a) the amount representing the credit
loss and (b) the amount related to all other factors. The amount
of the total OTTI impairment related to the credit loss shall be
recognized in earnings. The amount of the total OTTI related
to other factors shall be recognized in other comprehensive
income, net of applicable taxes.

In estimating OTTI losses, management considers, among
other things, (i) the length of time and the extent to which the
fair  value  has  been  less  than  cost,  (ii)  the  financial  condition
and  near-term  prospects  of  the  issuer,  and  (iii)  the  historical
and implied volatility of the fair value of the security.

Non-marketable equity securities are carried at cost.
Premiums and discounts are amortized or accreted over the
life of the related security as an adjustment to yield using the
interest method. Dividend and interest income are recognized
when earned. Realized gains and losses on securities sold are
derived using the specific identification method for determining
the cost of securities sold.

Investments  in  Federal  Reserve  Bank  (“FRB”)  and  Federal
Home Loan Bank (“FHLB”) stock are required for membership
in those organizations and are carried at cost since there is no
market value available. The FHLB New York continues to pay
dividends  and  repurchase  stock.  As  such,  the  Company  has
not recognized any impairment on its holdings of FHLB stock.

Loans

Loans are recorded at their current unpaid principal balance,
net of unearned income and unamortized loan fees and expenses,
which are amortized under the effective interest method over
the estimated lives of the loans. Interest income on loans is
accrued based on the principal amount outstanding.

For  all  loan  classes  within  the  Company’s  loan  portfolio,
loans are placed on nonaccrual status when timely collection
of principal and interest in accordance with contractual terms
is doubtful. Loans are transferred to nonaccrual status generally
when  principal  or  interest  payments  become  ninety  days
delinquent, unless the loan is well-secured and in the process
of  collection,  or  sooner  when  management  concludes  cir-
cumstances indicate that borrowers may be unable to meet
contractual  principal  or  interest  payments. When  a  loan  is
transferred  to  a  nonaccrual  status,  all  interest  previously
accrued  in  the  current  period  but  not  collected  is  reversed
against  interest  income  in  that  period.  Interest  accrued  in  a
prior  period  and  not  collected  is  charged-off  against  the
allowance for loan losses.

If ultimate repayment of a nonaccrual loan is expected, any
payments received are applied in accordance with contractual
terms. If ultimate repayment of principal is not expected, any
payment received on a nonaccrual loan is applied to principal
until ultimate repayment becomes expected. For all loan classes
within  the  Company’s  loan  portfolio,  nonaccrual  loans  are
returned  to  accrual  status  when  they  become  current  as  to
principal and interest and demonstrate a period of performance
under the contractual terms and, in the opinion of manage-
ment, are fully collectible as to principal and interest. For loans
in all portfolios, the principal amount is charged off in full or
in part as soon as management determines, based on available
facts, that the collection of principal in full is improbable. For
commercial loans, management considers specific facts and
circumstances relative to individual credits in making such a
determination.  For  consumer  and  residential  loan  classes,
management uses specific guidance and thresholds from the
Federal Financial Institutions Examination Council’s Uniform
Retail Credit Classification and Account Management Policy.
Commercial type loans are considered impaired when it is
probable that the borrower will not repay the loan according
to the original contractual terms of the loan agreement, and
all loan types are considered impaired if the loan is restructured
in a troubled debt restructuring (“TDR”). In determining that
we will be unable to collect all principal and interest payments
due in accordance with the contractual terms of the loan agree-
ments, we consider factors such as payment history and changes
in the financial condition of individual borrowers, local economic

NBT BANCORP 2016 FORM 10-K

55

conditions, historical loss experience and the conditions of the
various markets in which the collateral may be liquidated.

A loan is considered to be a TDR when the Company grants
a concession to the borrower because of the borrower’s financial
condition  that  the  Company  would  not  otherwise  consider.
Such concessions include the reduction of interest rates, for-
giveness  of  all  or  a  portion  of  principal  or  interest,  or  other
modifications  at  interest  rates  that  are  less  than  the  current
market rate for new obligations with similar risk. TDR loans are
nonaccrual  loans;  however,  they  can  be  returned  to  accrual
status after a period of performance, generally evidenced by
six months of compliance with their modified terms.

When the Company modifies a loan, management evaluates
any  possible  impairment  based  on  the  present  value  of  the
expected  future  cash  flows,  discounted  at  the  contractual
interest rate of the original loan agreement, except when the
sole (remaining) source of repayment for the loan is the oper-
ation or liquidation of the collateral. In these cases, management
uses the current fair value of the collateral, less selling costs,
instead of discounted cash flows. If management determines
that the value of the modified loan is less than the recorded
investment in the loan (net of previous charge-offs, deferred
loan  fees  or  costs  and  unamortized  premium  or  discount),
impairment is recognized.

Acquired Loans

Acquired loans are initially measured at fair value as of the
acquisition date without carryover of historical allowance for
loan losses.

For loans that meet the criteria stipulated in ASC 310-30—
Receivables—Loans and Debt Securities Acquired with Deteriorated
Credit Quality, the Company shall recognize the accretable yield,
which  is  defined  as  the  excess  of  all  cash  flows  expected  at
acquisition  over  the  initial  fair  value  of  the  loan,  as  interest
income on a level-yield basis over the expected remaining life
of the loan. The excess of the loan’s contractually required pay-
ments  over  the  cash  flows  expected  to  be  collected  is  the
nonaccretable  difference. The  nonaccretable  difference  shall
not be recognized as an adjustment of yield, a loss accrual, or
a valuation allowance. Decreases in the expected cash flows
in subsequent periods require the establishment of an allowance
for loan losses. Improvements in expected cash flows in future
periods  result  in  a  reduction  of  the  nonaccretable  discount,
with such amount reclassified as part of the accretable yield
and subsequently recognized in interest income over the remain-
ing  lives  of  the  acquired  loans  on  a  level-yield  basis  if  the
amount and timing of future cash flows is reasonably estimable.

Acquired loans that met the criteria for nonaccrual of interest
prior to the acquisition are considered performing upon acqui-
sition, regardless of whether the customer is contractually delin-
quent, if the Company can reasonably estimate the timing and
amount of the expected cash flows on such loans and if the
Company expects to fully collect the new carrying value of the
loans. As such, the Company may no longer consider the loan
to be nonaccrual or nonperforming and may accrue interest
on these loans, including the impact of any accretable yield.
As such, charge-offs on acquired loans are first applied to the
nonaccretable difference and then to any allowance for loan
losses recognized subsequent to acquisition.

For loans that meet the criteria stipulated in ASC 310-20—
Receivables—Nonrefundable Fees and Other Costs (“ASC  310-
20”), the Company shall amortize/accrete into interest income
the premium/discount determined at the date of purchase on
a level-yield basis over the life of the loan. Subsequent to the
acquisition date, the methods utilized to estimate the required
allowance for loan losses are similar to originated loans. Loans
accounted  for  under  ASC  310-20  are  placed  on  nonaccrual
status when past due in accordance with the Company’s nonac-
crual policy.

An  acquired  loan  may  be  resolved  either  through  receipt
of payment (in full or in part) from the borrower, the sale of
the loan to a third party, or foreclosure of the collateral. In the
event of a sale of the loan, a gain or loss on sale is recognized
and reported within noninterest income based on the difference
between the sales proceeds and the carrying amount of the
loan.  In  other  cases,  individual  loans  are  removed  from  the
pool based on comparing the amount received from its reso-
lution (fair value of the underlying collateral less costs to sell
in the case of a foreclosure) with its outstanding balance. Any
difference between these amounts is recorded as a charge-off
through the allowance for loan losses. Acquired loans subject
to modification are not removed from the pool even if those
loans would otherwise be deemed TDRs as the pool, and not
the individual loan, represents the unit of account.

Allowance for Loan Losses

The allowance for loan losses is the amount which, in the
opinion of management, is necessary to absorb probable losses
inherent  in  the  loan  portfolio. The  allowance  is  determined
based  upon  numerous  considerations,  including  local  and
regional conditions, the growth and composition of the loan
portfolio with respect to the mix between the various types of
loans and their related risk characteristics, a review of the value
of collateral supporting the loans, comprehensive reviews of

56

NBT BANCORP 2016 FORM 10-K

the  loan  portfolio  by  the  independent  loan  review  staff  and
management, as well as consideration of volume and trends
of delinquencies, nonperforming loans, and loan charge-offs.
Loan losses are charged off against the allowance, while recov-
eries  of  amounts  previously  charged  off  are  credited  to  the
allowance. As a result of tests of adequacy, required additions
to the allowance for loan losses are made periodically by charges
to the provision for loan losses.

The  allowance  for  loan  losses  related  to  impaired  loans
specifically  allocated  for  impairment  is  based  on  discounted
expected  cash  flows  using  the  loan’s  initial  effective  interest
rate or the fair value of the collateral for certain loans where
repayment  of  the  loan  is  expected  to  be  provided  solely  by
the underlying collateral (“collateral dependent”). The Company’s
impaired loans are generally collateral dependent. The Company
considers  the  estimated  cost  to  sell,  on  a  discounted  basis,
when determining the fair value of collateral in the measurement
of impairment if those costs are expected to reduce the cash
flows available to repay or otherwise satisfy the loans.

The allowance for loan losses for homogeneous non impaired
loans is calculated using a systematic methodology with both
a  quantitative  and  a  qualitative  analysis  that  is  applied  on  a
quarterly basis. For purposes of our allowance methodology,
the loan portfolio is segmented as described in Note 5. Each
segment has a distinct set of risk characteristics monitored by
management. We further assess and monitor risk and perform-
ance at a more disaggregated level which includes our internal
risk grading system for the commercial segments.

We  first  apply  historical  loss  rates  to  pools  of  loans  with
similar risk characteristics. Loss rates are calculated by historical
charge-offs that have occurred within each pool of loans over
the lookback period (“LBP”), multiplied by the loss emergence
period (“LEP”). The LBP represents the historical data period uti-
lized to calculate loss rates. The LEP is an estimate of the average
amount of time from the point at which a loss is incurred on a
loan to the point at which the loss is confirmed. In general, the
LEP will be shorter in an economic slowdown or recession and
longer during times of economic stability or growth, as customers
are better able to delay loss confirmation after a potential loss
event has occurred. In conjunction with our annual review of
the  ALL  assumptions,  we  update  our  study  of  LEPs  for  each
portfolio segment using our loan charge-off history.

After consideration of the historic loss analysis, management
applies additional qualitative adjustments so that the allowance
for loan losses is reflective of the inherent losses that exist in
the loan portfolio at the balance sheet date. Qualitative adjust-
ments  are  made  based  upon  size,  trend,  composition,  and
nature of loans; changes in lending policies and procedures,
including underwriting standards and collection, charge-offs

and recoveries; trends experienced in nonperforming and delin-
quent  loans;  current  economic  conditions  in  the  Company’s
market; portfolio concentrations that may affect loss experience
across one of more components of the portfolio; the effect of
external  factors  such  as  competition,  legal  and  regulatory
requirements; and the experience, ability, and depth of lending
management and staff. The evaluation of the various compo-
nents  of  the  allowance  for  loan  losses  requires  considerable
judgment in order to estimate inherent loss exposures. In addi-
tion, various regulatory agencies, as an integral component of
their examination process, periodically review the Company’s
allowance for loan losses. Such agencies may require the Com-
pany to make loan grade changes as well as recognize additions
to the allowance based on their examinations.

Management believes that the allowance for loan losses is
adequate. 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 or changes in the values of properties securing loans
in  the  process  of  foreclosure.  In  addition,  various  regulatory
agencies, as an integral part of their examination process, peri-
odically 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
which may not be currently available to management.

Premises and Equipment

Premises and equipment are stated at cost, less accumu-
lated depreciation. Depreciation of premises and equipment
is determined using the straight-line method over the estimated
useful lives of the respective assets. Expenditures for mainte-
nance, repairs, and minor replacements are charged to expense
as incurred.

Other Real Estate Owned

Other  real  estate  owned  (“OREO”)  consists  of  properties
acquired  through  foreclosure  or  by  acceptance  of  a  deed  in
lieu of foreclosure. These assets are recorded at the lower of
fair value of the asset acquired less estimated costs to sell or
“cost”  (defined  as  the  fair  value  at  initial  foreclosure).  At  the
time of foreclosure, or when foreclosure occurs in-substance,
the excess, if any, of the loan over the fair market value of the
assets received, less estimated selling costs, is charged to the
allowance for loan losses and any subsequent valuation write-
downs are charged to other expense. In connection with the
determination of the allowance for loan losses and the valu-
ation of OREO, management obtains appraisals for properties.

NBT BANCORP 2016 FORM 10-K

57

Operating costs associated with the properties are charged to
expense as incurred. Gains on the sale of OREO are included
in income when title has passed and the sale has met the min-
imum down payment requirements prescribed by GAAP. The
balance of OREO is recorded in other assets on the consolidated
balance sheets.

Goodwill and Other Intangible Assets

Goodwill represents the cost of acquired business in excess
of the fair value of the related net assets acquired. Goodwill is
not amortized but tested at the reporting unit level for impair-
ment  on  an  annual  basis  and  on  an  interim  basis  or  when
events or circumstances dictate. The Company has elected June
30  as  the  annual  impairment  testing  date  for  the  insurance
and retirement services reporting units and December 31 for
the Bank reporting unit.

The Company has the option to first assess qualitative factors,
by  performing  a  step  zero  qualitative  analysis,  to  determine
whether  the  existence  of  events  or  circumstances  leads  to  a
determination that it is more likely than not that the fair value
of  a  reporting  unit  is  less  than  its  carrying  amount.  If,  after
assessing the events or circumstances, the Company determines
it is not more likely than not that the fair value of a reporting
unit is greater than its carrying amount, the two-step impairment
test is not required. If the Company concludes otherwise, the
Company is required to perform the first step of the two-step
impairment test. In the first step of the goodwill impairment
test, the estimated fair value of a reporting unit is compared
to the carrying amount in order to determine if impairment is
indicated.  If  the  estimated  fair  value  exceeds  the  carrying
amount, the reporting unit is not deemed to be impaired. If
the  estimated  fair  value  is  below  the  carrying  value  of  the
reporting  unit,  the  second  step  of  the  goodwill  impairment
test is required to determine the amount of impairment. The
second step of the goodwill impairment test determines the
implied fair value of the goodwill that is compared to the car-
rying value of goodwill for the reporting unit to determine the
amount of the impairment.

Intangible  assets  that  have  indefinite  useful  lives  are  not
amortized,  but  are  tested  at  least  annually  for  impairment.
Intangible assets that have finite useful lives are amortized over
their useful lives. Core deposit intangibles and trust intangibles
at  the  Company  are  amortized  using  the  sum-of-the-years’-
digits method. Covenants not to compete are amortized on a
straight-line basis. Customer lists are amortized using an accel-
erated method. When facts and circumstances indicate potential
impairment  of  amortizable  intangible  assets,  the  Company
evaluates the recoverability of the asset carrying value, using

estimates of undiscounted future cash flows over the remaining
asset  life.  Any  impairment  loss  is  measured  by  the  excess  of
carrying value over fair value.

Determining the fair value of a reporting unit under the first
step of the goodwill impairment testing and determining the
fair value of individual assets and liabilities of a reporting unit
under the second step of the goodwill impairment test and in
determining the fair value of other intangible assets are judg-
mental and often involve the use of significant estimates and
assumptions. Estimates of fair value are primarily determined
using the discounted cash flows method, which uses significant
estimates  and  assumptions  including  projected  future  cash
flows, discount rates reflecting the market rate of return and
projected growth rates. Future events may impact such estimates
and assumptions and could cause the Company to conclude
that our goodwill or intangible assets have become impaired,
which would result in recording an impairment loss.

Bank-Owned Life Insurance

The Bank has purchased life insurance policies on certain
employees, key executives and directors. Bank-owned life insur-
ance is recorded at the amount that can be realized under the
insurance contract at the balance sheet date, which is the cash
surrender value adjusted for other charges or other amounts
due that are probable at settlement.

Treasury Stock

Treasury stock acquisitions are recorded at cost. Subsequent
sales of treasury stock are recorded on an average cost basis.
Gains on the sale of treasury stock are credited to additional
paid-in-capital. Losses on the sale of treasury stock are charged
to  additional  paid-in-capital  to  the  extent  of  previous  gains,
otherwise charged to retained earnings.

Income Taxes

Income taxes are accounted for under the asset and liability
method. Deferred income taxes are recognized for the future
tax consequences attributable to differences between the finan-
cial 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 tax-
able income in the years in which those temporary differences
are expected to be recovered or settled. The effect on deferred
taxes of a change in tax rates is recognized in income in the
period  that  includes  the  enactment  date. The  Company  rec-
ognizes interest accrued and penalties related to unrecognized
tax benefits in income tax expense.

58

NBT BANCORP 2016 FORM 10-K

Tax positions are recognized as a benefit only if it is “more
likely than not” that the tax position would be sustained in a
tax  examination,  with  a  tax  examination  being  presumed  to
occur. The amount recognized is the largest amount of tax ben-
efit that is greater than 50 percent likely of being realized on
examination.  For  tax  positions  not  meeting  the “more  likely
than not” test, no tax benefit is recorded.

Pension Costs

The Company maintains a noncontributory, defined benefit
pension  plan  covering  substantially  all  employees,  as  well  as
supplemental employee retirement plans covering certain exec-
utives  and  a  defined  benefit  postretirement  healthcare  plan
that covers certain employees. Costs associated with these plans,
based on actuarial computations of current and future benefits
for employees, are charged to current operating expenses.

Stock-Based Compensation

We maintain various long-term incentive stock benefit plans
under which we grant stock options, restricted stock awards,
and restricted stock units to certain directors and key employ-
ees. We recognize compensation expense in our consolidated
statements of income over the requisite service period, based
on the grant-date fair value of the award. For restricted stock
awards and units, we recognize compensation expense ratably
over the vesting period for the fair value of the award, measured
at the grant date. The fair values of options are estimated using
the Black-Scholes option pricing model.

The Company’s stock-based employee compensation plan

is described in Note 14.

Earnings Per Share

Basic  earnings  per  share  (“EPS”)  excludes  dilution  and  is
computed by dividing income available to common stockholders
by the weighted average number of common shares outstand-
ing for the period. Diluted EPS reflects the potential dilution
that could occur if securities or other contracts to issue common
stock were exercised or converted into common stock or resulted
in the issuance of common stock that then shared in the earn-
ings of the entity (such as the Company’s dilutive stock options
and restricted stock).

Comprehensive Income

At  the  Company,  comprehensive  income  represents  net
income plus other comprehensive income (loss), which consists
primarily of the net change in unrealized gains or losses on
securities available for sale for the period and changes in the
funded status of employee benefit plans. Accumulated other

comprehensive  (loss)  income  represents  the  net  unrealized
gains or losses on securities available for sale and the previously
unrecognized portion of the funded status of employee benefit
plans,  net  of  income  taxes,  as  of  the  consolidated  balance
sheet dates.

Derivative Instruments and Hedging Activities

The Company records all derivatives on the balance sheet
at  fair  value. The  accounting  for  changes  in  the  fair  value  of
derivatives  depends  on  the  intended  use  of  the  derivative,
whether the Company has elected to designate a derivative in
a hedging relationship and apply hedge accounting and whether
the hedging relationship has satisfied the criteria necessary to
apply hedge accounting. Derivatives designated and qualifying
as a hedge of the exposure to changes in the fair value of an
asset, liability, or firm commitment attributable to a particular
risk, such as interest rate risk, are considered fair value hedges.
Derivatives designated and qualifying as a hedge of the exposure
to  variability  in  expected  future  cash  flows,  or  other  types  of
forecasted transactions, are considered cash flow hedges. Hedge
accounting generally provides for the matching of the timing
of gain or loss recognition on the hedging instrument with the
recognition of the changes in the fair value of the hedged asset
or liability that are attributable to the hedged risk in a fair value
hedge or the earnings effect of the hedged forecasted transac-
tions in a cash flow hedge. The Company may enter into deriv-
ative contracts that are intended to economically hedge certain
of  its  risk,  even  though  hedge  accounting  does  not  apply  or
the Company elects not to apply hedge accounting.

For derivatives designated as fair value hedges, changes in
the fair value of the derivative and the hedged item related to
the hedged risk are recognized in earnings. Any hedge ineffec-
tiveness would be recognized in the income statement line item
pertaining to the hedged item. For derivatives designated as
cash flow hedges, changes in fair value of the effective portion
of the cash flow hedges are reported in other comprehensive
income. When the cash flows associated with the hedged item
are realized, the gain or loss included in other comprehensive
income is recognized in the consolidated statements of income.
When the Company purchases a portion of a commercial
loan that has an existing interest rate swap, it enters a risk par-
ticipation agreement with the counterparty and assumes the
credit risk of the loan customer related to the swap. Any fee paid
to the Company under a risk participation agreement is in con-
sideration of the credit risk of the counterparties and is recognized
in the income statement. Credit risk on the risk participation
agreements is determined after considering the risk rating, prob-
ability of default and loss given default of the counterparties.

Fair Value Measurements

Fair  value  is  an  exit  price,  representing  the  amount  that
would be received to sell an asset or paid to transfer a liability
in  an  orderly  transaction  between  market  participants.  Fair
value measurements are not adjusted for transaction costs. A
fair value hierarchy prioritizes the inputs to valuation techniques
used to measure fair value. The hierarchy gives the highest pri-
ority to unadjusted quoted prices in active markets for identical
assets  or  liabilities  (Level  1  measurements)  and  the  lowest
priority to unobservable inputs (Level 3 measurements). The
three levels of the fair value hierarchy are described below:

Level 1—Unadjusted quoted prices in active markets that
are accessible at the measurement date for identical, unrestricted
assets or liabilities;

Level  2—Quoted  prices  for  similar  assets  or  liabilities  in
active markets, quoted prices in markets that are not active,
or inputs that are observable, either directly or indirectly, for
substantially the full term of the asset or liability;

Level 3—Prices or valuation techniques that require inputs
that  are  both  significant  to  the  fair  value  measurement  and
unobservable (i.e., supported by little or no market activity).

A financial instrument’s level within the fair value hierarchy
is based on the lowest level of input that is significant to the
fair value measurement.

The types of instruments valued based on quoted market
prices in active markets include most U.S. government and
agency  securities,  many  other  sovereign  government  obli-
gations, liquid mortgage products, active listed equities and
most money market securities. Such instruments are generally
classified within Level 1 or Level 2 of the fair value hierarchy.
The  Company  does  not  adjust  the  quoted  price  for  such
instruments.

The types of instruments valued based on quoted prices
in markets that are not active, broker or dealer quotations, or
alternative  pricing  sources  with  reasonable  levels  of  price
transparency include most investment-grade and high-yield
corporate  bonds,  less  liquid  mortgage  products,  less  liquid
agency securities, less liquid listed equities, state, municipal
and provincial obligations, and certain physical commodities.
Such instruments are generally classified within Level 2 of the
fair value hierarchy.

Level 3 is for positions that are not traded in active markets
or are subject to transfer restrictions, valuations are adjusted
to reflect illiquidity and/or non-transferability, and such adjust-
ments  are  generally  based  on  available  market  evidence.  In
the  absence  of  such  evidence,  management’s  best  estimate
will  be  used.  Management’s  best  estimate  consists  of  both
internal and external support on certain Level 3 investments.

Subsequent to inception, management only changes Level 3
inputs and assumptions when corroborated by evidence such
as transactions in similar instruments, completed or pending
third-party transactions in the underlying investment or com-
parable entities, subsequent rounds of financing, recapitaliza-
tions and other transactions across the capital structure, offerings
in the equity or debt markets, and changes in financial ratios
or cash flows.

Other Financial Instruments

The Company is a party to certain other financial instruments
with  off-balance-sheet  risk  such  as  commitments  to  extend
credit, unused lines of credit, as well as certain mortgage loans
sold  to  investors  with  recourse. The  Company’s  policy  is  to
record such instruments when funded.

Standby letters of credit are conditional commitments issued
to guarantee the performance of 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 cus-
tomers.  Under  the  standby  letters  of  credit,  the  Company  is
required to make payments to the beneficiary of the letters of
credit  upon  request  by  the  beneficiary  contingent  upon  the
customer’s failure to perform under the terms of the underlying
contract with the beneficiary. Standby letters of credit typically
have one year expirations with an option to renew upon annual
review. The Company typically receives a fee for these trans-
actions. The fair value of standby letters of credit is recorded
upon inception.

Loan Sales and Loan Servicing

Loan sales are recorded when the sales are funded. Mort-
gage servicing rights are recorded at fair value upon sale of
the loan. Loans held for sale are recorded at the lower of cost
or market.

Repurchase Agreements

Repurchase agreements are accounted for as secured financ-
ing transactions since the Company maintains effective control
over the transferred securities and the transfer meets the other
criteria for such accounting. Obligations to repurchase securities
sold  are  reflected  as  a  liability  in  the  consolidated  balance
sheets. The securities underlying the agreements are delivered
to  a  custodial  account  for  the  benefit  of  the  dealer  or  bank
with whom each transaction is executed. The dealers or banks,
who may sell, loan or otherwise dispose of such securities to
other parties in the normal course of their operations, agree
to resell to the Company the same securities at the maturities
of the agreements.

Trust Operations

Reclassifications

Assets held by the Company in a fiduciary or agency capac-
ity  for  its  customers  are  not  included  in  the  accompanying
consolidated balance sheets, since such assets are not assets
of  the  Company. Trust  income  is  recognized  on  the  accrual
method based on contractual rates applied to the balances
of trust accounts.

Amounts in prior period consolidated financial statements
are  reclassified  whenever  necessary  to  confirm  with  current
period presentation.

Subsequent Events

The Company has evaluated subsequent events for potential
recognition and/or disclosure and there were none identified.

(2)  Acquisitions

In 2016, the Company acquired Actuarial Designs & Solutions,
Inc. for total consideration of $3.0 million and Columbia Ridge
Capital Management, Inc., for total consideration of $1.3 million.
As part of the acquisitions, the Company recorded goodwill of
$1.3 million and $0.8 million, respectively.

In 2015, the Company acquired Third Party Administrators,
Inc., a retirement plan administration company for total con-
sideration of $4.1 million. As part of the acquisition, the Com-
pany recorded goodwill of $2.3 million.

(3)  Securities

Declines in the fair value of HTM and AFS securities below
their  cost  that  are  deemed  to  be  other-than-temporary  are
reflected in earnings as realized losses or in other comprehensive
income, depending on whether the Company intends to sell
the security or more likely than not will be required to sell the
security  before  recovery  of  its  amortized  cost  basis  less  any
current-period credit loss, the OTTI shall be recognized in earn-
ings equal to the entire difference between the investment’s
amortized  cost  basis  and  its  fair  value  at  the  balance  sheet

date. If the Company does not intend to sell the security and
it is not more likely than not that the entity will be required to
sell the security before recovery of its amortized cost basis less
any current-period credit loss, the OTTI shall be separated into
(a) the amount representing the credit loss and (b) the amount
related to all other factors. The amount of the total OTTI related
to the credit loss shall be recognized in earnings. The amount
of the total OTTI related to other factors shall be recognized in
other comprehensive income, net of applicable taxes.

In estimating OTTI losses, management considers, among
other things, (i) the length of time and the extent to which the
fair  value  has  been  less  than  cost,  (ii)  the  financial  condition
and  near-term  prospects  of  the  issuer  and  (iii)  the  historical
and implied volatility of the fair value of the security.

Management has the intent to hold the securities classified
as HTM until they mature, at which time it is believed the Com-
pany  will  receive  full  value  for  the  securities. The  unrealized
losses on HTM debt securities are due to increases in market
interest rates over the yields available at the time the underlying
securities were purchased. When necessary, the Company has
performed a discounted cash flow analysis to determine whether
or not it will receive the contractual principal and interest on
certain securities. The fair value is expected to recover as the
bonds  approach  their  maturity  date  or  repricing  date  or  if
market yields for such investments decline.

Management  also  has  the  intent  to  hold  and  will  not  be
required to sell, the securities classified as AFS for a period of
time sufficient for a recovery of cost, which may be until maturity.
The unrealized losses on AFS debt securities are due to increases
in market interest rates over the yields available at the time the
underlying  securities  were  purchased. When  necessary,  the

Company  has  performed  a  discounted  cash  flow  analysis  to
determine whether or not it will receive the contractual principal
and interest on certain securities. The unrealized losses on equity
securities are due to declines in the fair value below the cost
basis of the securities. For AFS debt and equity securities, the
Company considers a decline in fair value to be other-than-tem-
porary  if  it  is  probable  that  the  Company  will  not  recover  its
cost basis. For equity securities, OTTI losses are recognized in
earnings if the Company intends to sell the security. In other
cases the Company considers the relevant factors noted above,
as well as the Company’s intent and ability to retain its investment
for a period of time sufficient to allow for any anticipated recovery
in market value, and whether evidence exists to support a real-
izable value equal to or greater than the cost basis. Any impair-
ment loss on an equity security is equal to the full difference
between the cost basis and the fair value of the security.

As of December 31, 2016 and 2015, management believes
the  impairments  detailed  in  the  table  above  are  temporary
and no OTTI losses have been realized in the Company’s con-
solidated statements of income.

Maturities  of  mortgage-backed,  collateralized  mortgage
obligations  and  asset-backed  securities  are  stated  based  on
their estimated average lives. Actual maturities may differ from
estimated average lives or contractual maturities because, in
certain cases, borrowers have the right to call or prepay obli-
gations with or without call or prepayment penalties.

Except for U.S. Government securities, there were no holdings,

Included in the above loans are net deferred loan origination
costs totaling $40.3 million and $38.7 million at December 31,
2016 and 2015, respectively. The Company had $0.6 million res-
idential loans held for sale as of December 31, 2016. The Company
had no residential loans held for sale as of December 31, 2015.
The  total  amount  of  loans  serviced  by  the  Company  for
unrelated third parties was $604.0 million and $616.1 million
at December 31, 2016 and 2015, respectively. At December 31,
2016 and 2015, the Company had $0.9 million and $1.1 million,
respectively, of mortgage servicing rights.

At  December  31,  2016  and  2015,  the  Company  serviced
$28.5  million  and  $25.1  million,  respectively,  of  agricultural

loans sold with recourse. Due to sufficient collateral on these
loans, no reserve is considered necessary at December 31, 2016
and 2015.

FHLB advances are collateralized by a blanket lien on the

Company’s residential real estate mortgages.

In the ordinary course of business, the Company has made
loans  at  prevailing  rates  and  terms  to  directors,  officers,  and
other related parties. Such loans, in management’s opinion, do
not present more than the normal risk of collectability or incor-
porate other unfavorable features. The aggregate amount of
loans  outstanding  to  qualifying  related  parties  and  changes
during the years are summarized as follows:

(5)  Allowance for Loan Losses and Credit Quality of Loans

Allowance for Loan Losses

The allowance for loan losses is maintained at a level esti-
mated by management to provide adequately for risk of prob-
able losses inherent in the current loan portfolio. The adequacy
of the allowance for loan losses is continuously monitored. It
is  assessed  for  adequacy  using  a  methodology  designed  to
ensure the level of the allowance reasonably reflects the loan
portfolio’s risk profile. It is evaluated to ensure that it is sufficient
to absorb all reasonably estimable credit losses inherent in the
current loan portfolio.

To  develop  and  document  a  systematic  methodology  for
determining  the  allowance  for  loan  losses,  the  Company  has
divided the loan portfolio into three segments, each with different
risk characteristics and methodologies for assessing risk. Those
segments are further segregated between our loans accounted
for under the amortized cost method (referred to as “originated”
loans) and loans acquired in a business combination (referred
to as “acquired” loans). Each portfolio segment is broken down
into class segments where appropriate. Class segments contain
unique measurement attributes, risk characteristics and methods

for monitoring and assessing risk that are necessary to develop
the  allowance  for  loan  losses.  Unique  characteristics  such  as
borrower type, loan type, collateral type, and risk characteristics
define each class segment. The following table illustrates the
portfolio and class segments for the Company’s loan portfolio:

Residential Real Estate Mortgages

Commercial Loans

Commercial—The Company offers a variety of loan options
to meet the specific needs of our commercial customers includ-
ing term loans, time notes and lines of credit. Such loans are
made available to businesses for working capital such as inven-
tory and receivables, business expansion and equipment pur-
chases. Generally, a collateral lien is placed on equipment or
other assets owned by the borrower. These loans carry a higher
risk  than  commercial  real  estate  loans  by  the  nature  of  the
underlying  collateral,  which  can  be  business  assets  such  as
equipment and accounts receivable and is generally less liquid
than real estate. To reduce the risk, management also attempts
to secure real estate as collateral and obtain personal guarantees
of the borrowers.

Commercial Real Estate—The Company offers commercial
real estate loans to finance real estate purchases, refinancings,
expansions and improvements to commercial properties. Com-
mercial real estate loans are made to finance the purchases of
real property which generally consists of real estate with com-
pleted structures. These commercial real estate loans are secured
by first liens on the real estate, which may include apartments,
commercial structures, housing businesses, healthcare facilities,
and other non owner-occupied facilities. These loans are typ-
ically less risky than commercial loans, since they are secured
by real estate and buildings. The Company’s underwriting analy-
sis includes credit verification, independent appraisals, a review
of the borrower’s financial condition, and a detailed analysis
of the borrower’s underlying cash flows. These loans are typically
originated in amounts of no more than 80% of the appraised
value of the property.

Agricultural—The Company offers a variety of agricultural
loans to meet the needs of our agricultural customers including
term loans, time notes, and lines of credit. These loans are made
to  purchase  livestock,  purchase  and  modernize  equipment,
and finance seasonal crop expenses. Generally, a collateral lien
is  placed  on  the  livestock,  equipment,  produce  inventories,
and/or receivables owned by the borrower. These loans may
carry a higher risk than commercial and agricultural real estate
loans  due  to  the  industry  price  volatility  and  the  perishable
nature of the underlying collateral. To reduce these risks, man-
agement  may  attempt  to  secure  these  loans  with  additional
real  estate  collateral,  obtain  personal  guarantees  of  the  bor-
rowers,  or  obtain  government  loan  guarantees  to  provide
further support.

Agricultural Real Estate—The Company offers real estate
loans to our agricultural customers to finance farm related real
estate purchases, refinancings, expansions, and improvements
to  agricultural  properties.  Agricultural  real  estate  loans  are
made  to  finance  the  purchases  and  improvements  of  farm
properties that generally consist of barns, production facilities,
and land. The agricultural real estate loans are secured by first
liens on the farm real estate. Because they are secured by land
and buildings, these loans may be less risky than agricultural
loans. The Company’s underwriting analysis includes credit ver-
ification,  independent  appraisals,  a  review  of  the  borrower’s
financial condition, and a detailed analysis of the borrower’s
underlying cash flows. These loans are typically originated in
amounts of no more than 75% of the appraised value of the
property.  Government  loan  guarantees  may  be  obtained  to
provide further support.

Business Banking—The Company offers a variety of loan
options  to  meet  the  specific  needs  of  our  business  banking
customers including term loans, business banking mortgages
and  lines  of  credit.  Such  loans  are  generally  less  than  $0.8
million and are made available to businesses for working capital
such as inventory and receivables, business expansion, equip-
ment purchases, and agricultural needs. Generally, a collateral
lien is placed on equipment or other assets owned by the bor-
rower such as inventory and/or receivables. These loans carry
a higher risk than commercial loans due to the smaller size of
the borrower and lower levels of capital. To reduce the risk, the
Company  obtains  personal  guarantees  of  the  owners  for  a
majority of the loans.

Consumer Loans

Indirect—The Company maintains relationships with many
dealers primarily in the communities that we serve. Through
these  relationships,  the  company  finances  the  purchases  of
automobiles and recreational vehicles (such as campers, boats,
etc.)  indirectly  through  dealer  relationships.  Approximately
70% of the indirect relationships represent automobile financing.
Most of these loans carry a fixed rate of interest with principal
repayment  terms  typically  ranging  from  three  to  six  years,
based upon the nature of the collateral and the size of the loan.
The majority of indirect consumer loans are underwritten on
a secured basis using the underlying collateral being financed.
Home Equity—The Company offers fixed home equity loans
as well as home equity lines of credit to consumers to finance
home improvements, debt consolidation, education and other
uses. Consumers are able to borrower up to 85% of the equity
in their homes. The Company originates home equity lines of
credit and second mortgage loans (loans secured by a second
lien position on one-to-four-family residential real estate). These
loans carry a higher risk than first mortgage residential loans
as they are in a second position with respect to collateral. Risk
is reduced through underwriting criteria, which include credit
verification, appraisals, a review of the borrower’s financial con-
dition, and personal cash flows. A security interest, with title
insurance when necessary, is taken in the underlying real estate.
Direct—The Company offers a variety of consumer install-
ment loans to finance vehicle purchases, mobile home purchases
and personal expenditures. Most of these loans carry a fixed
rate of interest with principal repayment terms typically ranging
from one to ten years, based upon the nature of the collateral
and the size of the loan. The majority of consumer loans are
underwritten on a secured basis using the underlying collateral
being financed or a customer’s deposit account. In addition to
installment  loans,  the  Company  also  offers  personal  lines  of
credit  and  overdraft  protection.  A  minimal  amount  of  loans
are unsecured, which carry a higher risk of loss.

Residential Real Estate Loans

Residential real estate loans consist primarily of loans secured
by  first  or  second  deeds  of  trust  on  primary  residences. We
originate  adjustable-rate  and  fixed-rate,  one-to-four-family

residential real estate loans for the construction, purchase or
refinancing of a mortgage. These loans are collateralized by
owner-occupied properties located in the Company’s market
area. When market conditions are favorable, for longer term,
fixed-rate residential mortgages without escrow, the Company
retains  the  servicing,  but  sells  the  right  to  receive  principal
and interest to Freddie Mac when market conditions are favor-
able. This  practice  allows  the  Company  to  manage  interest
rate risk, liquidity risk, and credit risk. Loans on one-to-four-
family residential real estate are generally originated in amounts
of no more than 85% of the purchase price or appraised value
(whichever is lower), or have private mortgage insurance. Mort-
gage title insurance and hazard insurance are normally required.
Construction loans have a unique risk, because they are secured
by an incomplete dwelling. This risk is reduced through periodic
site inspections, including one at each loan draw period.

Allowance for Loan Loss Calculation

Management  considers  the  accounting  policy  relating  to
the allowance for loan losses to be a critical accounting policy
given the inherent uncertainty in evaluating the levels of the
allowance required to cover credit losses in the portfolio and
the material effect that such judgments can have on the con-
solidated results of operations.

In addition, various regulatory agencies, as an integral com-
ponent of their examination process, periodically review the
Company’s allowance for loan losses. Such agencies may require
the Company to make loan grade changes as well as recognize
additions to the allowance based on their examinations.

After  a  thorough  consideration  of  the  factors  discussed
above, any required additions to the allowance for loan losses
are  made  periodically  by  charges  to  the  provision  for  loan
losses. These charges are necessary to maintain the allowance
at a level which management believes is reasonably reflective
of overall inherent risk of probable loss in the portfolio. While
management  uses  available  information  to  recognize  losses
on loans, additions to the allowance may fluctuate from one
reporting period to another. These fluctuations are reflective
of  changes  in  risk  associated  with  portfolio  content  and/or
changes in management’s assessment of any or all of the deter-
mining factors discussed above.

For acquired loans, to the extent that we experience dete-
rioration in borrower credit quality resulting in a decrease in
our expected cash flows subsequent to acquisition of the loans,
an  allowance  for  loan  losses  would  be  established  based  on
our estimate of future credit losses over the remaining life of
the loans. The allowance for loan losses for the acquired loan

portfolio  totaled  $0.7  million  as  of  December  31,  2016  and
December 31, 2015. Net charge-offs related to acquired loans
totaled approximately $0.5 million, $2.7 million, and $4.8 million
during  the  years  ended  December  31,  2016,  December  31,
2015 and December 31, 2014, respectively, and are included
in the table above.

There  were  no  material  commitments  to  extend  further
credit to borrowers with nonperforming loans as of December

The methodology used to establish the allowance for loan
losses on impaired loans incorporates specific allocations on
loans analyzed individually. Classified loans, including all TDRs
and nonaccrual commercial loans that are graded Substandard
or below, with outstanding balances of $0.8 million or more
are evaluated for impairment through the Company’s quarterly

status review process. In determining that we will be unable
to collect all principal and interest payments due in accordance
with the contractual terms of the loan agreements, we consider
factors such as payment history and changes in the financial
condition of individual borrowers, local economic conditions,
historical  loss  experience  and  the  conditions  of  the  various
markets in which the collateral may be liquidated. For loans
that  are  evaluated  for  impairment,  impairment  is  measured
by  one  of  three  methods:  1)  the  fair  value  of  collateral  less

cost to sell, 2) present value of expected future cash flows or
3)  the  loan’s  observable  market  price. These  impaired  loans
are reviewed on a quarterly basis for changes in the measure-
ment of impairment. For impaired loans measured using the
present value of expected cash flow method, any change to
the previously recognized impairment loss is recognized as a

change to the allowance account and recorded in the consol-
idated statement of income as a component of the provision
for credit losses.

While we continue to adhere to prudent underwriting stan-
dards, as a lender we may be adversely impacted by general
economic weaknesses and, in particular, a sharp downturn in
the housing market nationally. Decreases in real estate values
could adversely affect the value of property used as collateral
for  our  loans.  Adverse  changes  in  the  economy  may  have  a
negative effect on the ability of our borrowers to make timely
loan payments, which would have an adverse impact on our
earnings.  A  further  increase  in  loan  delinquencies  would
decrease  our  net  interest  income  and  adversely  impact  our
loan  loss  experience,  causing  increases  in  our  provision  and
allowance for loan losses.

The Company has developed an internal loan grading system
to evaluate and quantify the Bank’s loan portfolio with respect
to quality and risk. The system focuses on, among other things,
financial strength of borrowers, experience and depth of man-
agement, primary and secondary sources of repayment, pay-
ment  history,  nature  of  the  business,  outlook  on  particular

industries. The internal grading system enables the Company
to monitor the quality of the entire loan portfolio on a contin-
uous  basis  and  provide  management  with  an  early  warning
system, enabling recognition and response to problem loans
and potential problem loans.

Commercial Grading System

For commercial and agricultural loans, the Company uses a
grading  system  that  relies  on  quantifiable  and  measurable
characteristics when available. This would include comparison
of financial strength to available industry averages, comparison
of transaction factors (loan terms and conditions) to loan policy,
and  comparison  of  credit  history  to  stated  repayment  terms
and  industry  averages.  Some  grading  factors  are  necessarily
more subjective such as economic and industry factors, regu-
latory environment, and management. Commercial loans are
graded as Doubtful, Substandard, Special Mention and Pass.

•  Doubtful

A Doubtful loan has a high probability of total or substantial
loss,  but  because  of  specific  pending  events  that  may
strengthen the asset, its classification as loss is deferred.
Doubtful borrowers are usually in default, lack adequate
liquidity  or  capital,  and  lack  the  resources  necessary  to
remain an operating entity. Pending events can include
mergers, acquisitions, liquidations, capital injections, the
perfection of liens on additional collateral, the valuation
of collateral, and refinancing. Generally, pending events
should  be  resolved  within  a  relatively  short  period  and
the ratings will be adjusted based on the new information.
Because of high probability of loss, nonaccrual treatment
is required for Doubtful assets.

•  Substandard

Substandard  loans  have  a  high  probability  of  payment
default, or they have other well-defined weaknesses. They
require more intensive supervision by bank management.
Substandard loans are generally characterized by current
or  expected  unprofitable  operations,  inadequate  debt
service coverage, inadequate liquidity, or marginal capi-
talization. Repayment may depend on collateral or other
credit  risk  mitigants.  For  some  Substandard  loans,  the
likelihood  of  full  collection  of  interest  and  principal
may  be in doubt and should be placed on nonaccrual.
Although Substandard assets in the aggregate will have
a  distinct  potential  for  loss,  an  individual  asset’s  loss
potential does not have to be distinct for the asset to be
rated Substandard.

in  compliance  with  loan  covenants,  and  payments  are
generally made as agreed. Pass loans range from superior
quality to fair quality.

Business Banking Grading System

Business  Banking  loans  are  graded  as  either  Classified  or

Non-classified.

•  Classified

Classified loans are inadequately protected by the current
worth and paying capacity of the obligor or, if applicable,
the  collateral  pledged. These  loans  have  a  well-defined
weakness, or weaknesses, that jeopardize the liquidation
of the debt, or in some cases make collection or liquidation
in full, on the basis of currently existing facts, conditions,
and values, highly questionable and improbable. They are
characterized by the distinct possibility that the Company
will sustain some loss if the deficiencies are not corrected.
Classified loans have a high probability of payment default,
or  a  high  probability  of  total  or  substantial  loss. These
loans require more intensive supervision by management
and  are  generally  characterized  by  current  or  expected
unprofitable operations, inadequate debt service coverage,
inadequate liquidity, or marginal capitalization. Repayment
may depend on collateral or other credit risk mitigants.
When the likelihood of full collection of interest and prin-
cipal may be in doubt; classified loans are considered to
have a nonaccrual status. In some cases, Classified loans
are considered uncollectible and of such little value that
their continuance as assets is not warranted.

•  Special Mention

•  Non-classified

Special  Mention  loans  have  potential  weaknesses  that
may,  if  not  checked  or  corrected,  weaken  the  asset  or
inadequately  protect  the  Company’s  position  at  some
future date. These loans pose elevated risk, but their weak-
ness does not yet justify a Substandard classification. Bor-
rowers  may  be  experiencing  adverse  operating  trends
(declining revenues or margins) or may be struggling with
an ill-proportioned balance sheet (e.g., increasing inventory
without an increase in sales, high leverage, tight liquidity).
Adverse economic or market conditions, such as interest
rate increases or the entry of a new competitor, may also
support a special mention rating. Although a Special Men-
tion loan has a higher probability of default than a pass
asset, its default is not imminent.

•  Pass

Loans graded as Pass encompass all loans not graded as
Doubtful, Substandard, or Special Mention. Pass loans are

Loans graded as Non-classified encompass all loans not
graded as Classified. Non-classified loans are in compliance
with loan covenants, and payments are generally made
as agreed.

Consumer and Residential Mortgage 
Grading System

Consumer  and  Residential  Mortgage  loans  are  graded  as

either Nonperforming or Performing.

•  Nonperforming

Nonperforming loans are loans that are 1) over 90 days
past due and interest is still accruing or 2) on nonaccrual
status.

•  Performing

All loans not meeting any of these criteria are considered
Performing.

Troubled Debt Restructuring

Substantially all modifications include one or a combination
of the following: an extension of the maturity date at a stated
rate of interest lower than the current market rate for new debt
with  similar  risk;  temporary  reduction  in  the  interest  rate;  or
change in scheduled payment amount. Residential and home
equity TDRs occurring during 2016 and 2015 were due to the
reduction in the interest rate or extension of the term. In 2015,

commercial and business banking TDRs were both a reduction
of the interest rate and change in terms.

The  following  tables  illustrate  the  recorded  investment
and number of modifications for modified loans, including
the recorded investment in the loans prior to a modification
and the recorded investment in the loans after restructuring
that  occurred  during  the  years  ended  December  31,  2016
and 2015:

Time deposits of $250,000 or more aggregated $84.3 million and $84.9 million December 31, 2016 and 2015, respectively.

(9)  Short-Term Borrowings

In addition to the liquidity provided by balance sheet cash
flows,  liquidity  must  also  be  supplemented  with  additional
sources such as credit lines from correspondent banks as well
as borrowings from the FHLB and the Federal Reserve Bank.
Other funding alternatives may also be appropriate from time
to time, including wholesale and retail repurchase agreements
and brokered certificate of deposit (“CD”) accounts.

Short-term  borrowings  totaled  $681.7  million  and  $442.5
million at December 31, 2016 and 2015, respectively, and consist
of Federal funds purchased and securities sold under repurchase
agreements, which generally represent overnight borrowing
transactions, and other short-term borrowings, primarily FHLB
advances, with original maturities of one year or less.

The Company has unused lines of credit with the FHLB and
access to brokered deposits available for short-term financing
of approximately $1.9 billion and $2.1 billion at December 31,
2016 and 2015, respectively. Borrowings on the FHLB lines are
secured by FHLB stock, certain securities and one-to-four family

first lien mortgage loans. Securities collateralizing repurchase
agreements are held in safekeeping by nonaffiliated financial
institutions and are under the Company’s control.

(10)  Long-Term Debt

Long-term debt consists of obligations having an original
maturity at issuance of more than one year. A majority of the
Company’s long-term debt is comprised of FHLB advances col-
lateralized by the FHLB stock owned by the Company, certain

of its mortgage-backed securities and a blanket lien on its res-
idential real estate mortgage loans. A summary as of December

(11)  Junior Subordinated Debt

The  Company  sponsors  five  business  trusts,  CNBF  Capital
Trust  I,  NBT  Statutory Trust  I,  NBT  Statutory Trust  II,  Alliance
Financial Capital Trust I and Alliance Financial Capital Trust II
(collectively, the “Trusts”). The Company’s junior subordinated
debentures  include  amounts  related  to  the  Company’s  NBT
Statutory Trust I and II as well as junior subordinated debentures
associated with one statutory trust affiliate that was acquired
from our merger with CNB Financial Corp. and two statutory
trusts that were acquired from our acquisition of Alliance Finan-
cial Corporation (“Alliance”). The Trusts were formed for the pur-
pose of issuing company-obligated mandatorily redeemable
trust preferred securities to third-party investors and investing
in the proceeds from the sale of such preferred securities solely
in junior subordinated debt securities of the Company for gen-
eral corporate purposes. The Company guarantees, on a limited
basis, payments of distributions on the trust preferred securities
and payments on redemption of the trust preferred securities.
The Trusts are VIEs for which the Company is not the primary
beneficiary,  as  defined  by  GAAP.  In  accordance  with  GAAP,

the accounts of the Trusts are not included in the Company’s
consolidated  financial  statements.  See  Note  1  for  additional
information about the Company’s consolidation policy.

The  debentures  held  by  each  trust  are  the  sole  assets  of
that trust. The Trusts hold, as their sole assets, junior subordinated
debentures of the Company with face amounts totaling $98.0
million  at  December  31,  2016. The  Company  owns  all  of  the
common securities of the Trusts and has accordingly recorded
$3.2 million in equity method investments classified as other
assets  in  our  consolidated  balance  sheets  at  December  31,
2016. The Company owns all of the common stock of the Trusts,
which have issued trust preferred securities in conjunction with
the Company issuing trust preferred debentures to the Trusts.
The terms of the trust preferred debentures are substantially
the same as the terms of the trust preferred securities.

As  of  December  31,  2016,  the Trusts  had  the  following
trust preferred securities outstanding and held the following
junior subordinated debentures of the Company (dollars in
thousands):

The  Company’s  junior  subordinated  debentures  are
redeemable prior to the maturity date at our option upon each
trust’s stated option repurchase dates, and from time to time
thereafter. These debentures are also redeemable in whole at
any time upon the occurrence of specific events defined within
the trust indenture. Our obligations under the debentures and
related documents, taken together, constitute a full and uncon-
ditional guarantee by the Company of the issuers’ obligations
under the trust preferred securities. The Company owns all of
the common stock of the Trusts, which have issued trust pre-
ferred securities in conjunction with the Company issuing trust
preferred debentures to the Trusts. The terms of the trust pre-
ferred debentures are substantially the same as the terms of
the trust preferred securities.

With respect to the Trusts, the Company has the right to
defer  payments  of  interest  on  the  debentures  issued  to  the
Trusts at any time or from time to time for a period of up to
ten  consecutive  semi-annual  periods  with  respect  to  each
deferral period. Under the terms of the debentures, if in certain

circumstances there is an event of default under the debentures
or  the  Company  elects  to  defer  interest  on  the  debentures,
the Company may not, with certain exceptions, declare or pay
any dividends or distributions on its capital stock or purchase
or acquire any of its capital stock.

Despite the fact that the Trusts are not included in the Com-
pany’s  consolidated  financial  statements,  $97  million  of  the
$101 million in trust preferred securities issued by these sub-
sidiary trusts is included in the Tier 1 capital of the Company
for regulatory capital purposes as allowed by the Federal Reserve
Board (NBT Bank owns $1.0 million of CNBF Trust I securities).
The Dodd-Frank Wall Street Reform and Consumer Protection
Act of 2010 requires bank holding companies with assets greater
than $500 million to be subject to the same capital requirements
as insured depository institutions, meaning, for instance, that
such bank holding companies will not be able to count trust
preferred securities issued after May 19, 2010 as Tier 1 capital.
The aforementioned Trusts are grandfathered with respect to
this enactment based on their date of issuance.

Realization  of  deferred  tax  assets  is  dependent  upon  the
generation of future taxable income or the existence of sufficient
taxable income within the available carryback period. A valuation
allowance is provided when it is more likely than not that some
portion of the deferred tax asset will not be realized. Based on
available evidence, gross deferred tax assets will ultimately be

realized and a valuation allowance was not deemed necessary
at December 31, 2016 and 2015.

The following is a reconciliation of the provision for income
taxes  to  the  amount  computed  by  applying  the  applicable
Federal statutory rate of 35% to income before taxes:

mine if significant changes will occur over the next 12 months.
As  of  December  31,  2016,  no  significant  changes  to  UTBs
are projected; however, tax audit examinations are possible.

The Company recognized an insignificant amount of interest
expense  related  to  UTBs  in  the  consolidated  statement  of
income for the year ended December 31, 2016.

The Company is no longer subject to U.S. Federal tax exami-
nation by tax authorities for years prior to 2013 and New York

audit in the state of New York for tax years 2011, 2012 and 2013.

(13)  Employee Benefit Plans

Defined Benefit Post-retirement Plans

The Company has a qualified, noncontributory, defined ben-
efit  pension  plan  (“the  Plan”)  covering  substantially  all  of  its
employees at December 31, 2016. Benefits paid from the plan
are based on age, years of service, compensation, social security
benefits, and are determined in accordance with defined for-
mulas. The Company’s policy is to fund the Plan in accordance
with Employee Retirement Income Security Act of 1974 stan-
dards.  Assets  of  the  Plan  are  invested  in  bonds  and  publicly
traded stocks and mutual funds. Prior to January 1, 2000, the
Plan  was  a  traditional  defined  benefit  plan  based  on  final
average compensation. On January 1, 2000, the Plan was con-
verted to a cash balance plan with grandfathering provisions
for existing participants. Effective March 1, 2013, the Plan was

amended. Benefit accruals for participants who, as of January
1,  2000,  elected  to  continue  participating  in  the  traditional
defined benefit plan design were frozen as of March 1, 2013.

In May 2013, the noncontributory, frozen, defined benefit
pension  plan  assumed  from  Alliance  in  the  acquisition  was
merged into the Plan.

In addition to the Plan, the Company provides supplemental
employee retirement plans to certain current and former exec-
utives. The Company also assumed supplemental retirement
plans for certain current and former executives in the Alliance
acquisition.

The  supplemental  employee  retirement  plans  and  the
defined benefit pension plan are collectively referred to herein
as “Pension Benefits.”

Also, the Company provides certain health care benefits for
retired  employees.  Benefits  are  accrued  over  the  employees’
active service period. Only employees that were employed by
NBT Bank on or before January 1, 2000 are eligible to receive
post-retirement health care benefits. The Plan is contributory
for  participating  retirees,  requiring  participants  to  absorb
certain deductibles and coinsurance amounts with contribu-
tions adjusted annually to reflect cost sharing provisions and
benefit limitations called for in the Plan. Employees become
eligible for these benefits if they reach normal retirement age
while  working  for  the  Company.  For  eligible  employees
described above, the Company funds the cost of post-retire-
ment health care as benefits are paid. The Company elected
to recognize the transition obligation on a delayed basis over
twenty years. In addition, the Company assumed post-retirement
medical life insurance benefits for certain Alliance employees,

retirees and their spouses, if applicable, in the Alliance acqui-
sition. These post-retirement benefits are referred to herein as
“Other Benefits.”

Accounting standards require an employer to: (1) recognize
the overfunded or underfunded status of defined benefit post-
retirement plans, which is measured as the difference between
plan assets at fair value and the benefit obligation, as an asset
or liability in its balance sheet; (2) recognize changes in that
funded status in the year in which the changes occur through
comprehensive income; and (3) measure the defined benefit
plan  assets  and  obligations  as  of  the  date  of  its  year-end
balance sheet.

The components of accumulated other comprehensive loss,
which have not yet been recognized as components of net peri-
odic benefit cost, related to pensions and other post-retirement
benefits at December 31, 2016 and 2015 are summarized below:

The Company made contributions to the plan totaling $5.6

The  Company  did  not  make  any  contributions  to  the  plan
during the twelve months ended December 31, 2015 and 2014.
For measurement purposes, the annual rates of increase
in  the  per  capita  cost  of  covered  medical  and  prescription
drug benefits for fiscal year 2016 were assumed to be 6.5%
to 10.5% percent. The rates were assumed to decrease grad-
ually  to  3.9%  for  fiscal  year  2075  and  remain  at  that  level
thereafter. Assumed health care cost trend rates have a sig-
nificant effect on amounts reported for health care plans. A
one-percentage point change in the health care trend rates
would have the following effects as of and for the year ended
December 31, 2016:

Plan Investment Policy

The Company’s key investment objectives in managing its
defined  benefit  plan  assets  are  to  ensure  that  present  and
future benefit obligations to all participants and beneficiaries
are  met  as  they  become  due;  to  provide  a  total  return  that,
over the long-term, maximizes the ratio of the plan assets to
liabilities, while minimizing the present value of required Com-
pany contributions, at the appropriate levels of risk; to meet

statutory requirements and regulatory agencies’ requirements;
and to satisfy applicable accounting standards. The Company
periodically evaluates the asset allocations, funded status, rate
of return assumption and contribution strategy for satisfaction
of our investment objectives.

The target and actual allocations expressed as a percentage

of the defined benefit pension plan’s assets are as follows:

The plan had no financial instruments recorded at fair value

on a non-recurring basis as of December 31, 2016 and 2015.

Determination of Assumed Rate of Return

The expected long-term rate-of-return on assets was 7.0%
at December 31, 2016 and December 31, 2015. This assumption
represents  the  rate  of  return  on  plan  assets  reflecting  the
average rate of earnings expected on the funds invested or to
be invested to provide for the benefits included in the projected
benefit  obligation. The  assumption  has  been  determined  by
reflecting expectations regarding future rates of return for the
portfolio considering the asset distribution and related historical
rates  of  return. The  appropriateness  of  the  assumption  is
reviewed annually.

Employee 401(k) and Employee 
Stock Ownership Plans

The Company maintains a 401(k) and employee stock own-
ership plan (the “401(k) Plan”). The Company contributes to the

(14)  Stock-Based Compensation

401(k)  Plan  based  on  employees’  contributions  out  of  their
annual salaries. In addition, the Company may also make dis-
cretionary contributions to the 401(k) Plan based on profitability.
Participation in the 401(k) Plan is contingent upon certain age
and service requirements. The employer contributions associated
with the 401(k) Plan were $2.7 million in 2016, $2.5 million in
2015, and $2.8 million in 2014.

Other Retirement Benefits

Included in other liabilities is $2.6 million and $2.8 million
at  December  31,  2016  and  December  31,  2015,  respectively,
for  supplemental  retirement  benefits  for  retired  executives
from legacy plans assumed in acquisitions. The Company rec-
ognized  $0.2,  $0.3  and  $0.1  million  in  expense  for  the  years
ended December 31, 2016, December 31, 2015, and December
31, 2014, respectively, related to these plans.

In April 2008, the Company adopted the NBT Bancorp Inc.
2008 Omnibus Incentive Plan (the “Stock Plan”). Under the terms
of the Stock Plan, options and other equity-based awards are
granted to directors and employees to increase their direct pro-
prietary interest in the operations and success of the Company.
The Stock Plan assumed all prior equity-based incentive plans
and any new equity-based awards are granted under the terms
of the Stock Plan. Under terms of the Stock Plan, stock options
are granted to purchase shares of the Company’s common stock
at a price equal to the fair market value of the common stock
on the date of the grant. Options granted have a vesting period

of four years and terminate ten years from the date of the grant.
Shares issued as a result of stock option exercises and vesting
of restricted shares and stock unit awards are funded from the
Company’s treasury stock. Restricted shares granted under the
Plan vest after five years for employees and three years for non-
employee  directors.  Restricted  stock  units  granted  under  the
Stock Plan may have different terms and conditions. Performance
shares and units granted under the Stock Plan for executives
may have different terms and conditions. Since 2011, the Com-
pany primarily grants restricted stock unit awards. Stock option
grants since that time were reloads of existing grants.

Certain restrictions exist regarding the ability of the subsidiary
bank to transfer funds to the Company in the form of cash div-
idends. The approval of the Office of Comptroller of the Currency
(the “OCC”) is required to pay dividends when a bank fails to
meet certain minimum regulatory capital standards or when
such  dividends  are  in  excess  of  a  subsidiary  bank’s  earnings
retained  in  the  current  year  plus  retained  net  profits  for  the
preceding two years as specified in applicable OCC regulations.
At  December  31,  2016,  approximately  $102.5  million  of  the
total stockholders’ equity of the Bank was available for payment
of  dividends  to  the  Company  without  approval  by  the  OCC.
The Bank’s ability to pay dividends also is subject to the Bank

(16)  Regulatory Capital Requirements

being in compliance with regulatory capital requirements. The
Bank is currently in compliance with these requirements. Under
the State of Delaware General Corporation Law, the Company
may declare and pay dividends either out of accumulated net
retained earnings or capital surplus.

Under  a  previously  disclosed  stock  repurchase  plan,  the
Company purchased 675,535 shares of its common stock during
the twelve month period ended December 31, 2016, for a total
of $17.2 million at an average price of $25.45 per share. There
are 1,000,000 shares available for repurchase under this plan,
which expires on December 31, 2017.

The Company and the Bank are subject to various regulatory
capital requirements administered by the federal banking agen-
cies. 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 consolidated financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt
corrective action, the Bank must meet specific capital guidelines
that involve quantitative measures of NBT Bank’s assets, liabilities,
and certain off-balance sheet items as calculated under regulatory

accounting  practices. The  capital  amounts  and  classifications
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 Company and the Bank to maintain
minimum amounts and ratios (set forth in the table below) of
total  and Tier  1  Capital  to  risk-weighted  assets  and  of Tier  1
capital to average assets. As of December 31, 2016 and 2015,
the Company and the Bank meet all capital adequacy require-
ments to which they were subject.

Under their prompt corrective action regulations, regulatory
authorities  are  required  to  take  certain  supervisory  actions
(and may take additional discretionary actions) with respect
to an undercapitalized institution. Such actions could have a
direct material effect on an institution’s financial statements.
The regulations establish a framework for the classification of
banks into five categories: well-capitalized, adequately capi-
talized, under capitalized, significantly under capitalized, and
critically under capitalized. As of December 31, 2016, the most
recent notification from the Bank’s regulators 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 1 risk-
based, and Tier 1 Capital to Average Asset ratios as set forth

in  the  table  below. There  are  no  conditions  or  events  since
that notification that management believes have changed the
Bank’s category.

Beginning  in  2016,  in  addition  to  maintaining  minimum
capital ratios, the Company is subject to a capital conservation
buffer  (“Buffer”)  above  the  minimum  to  avoid  restriction  on
capital  distributions  and  discretionary  bonus  paychecks  to
officers.  At  December  31,  2016  the  Buffer  was  0.625%. The
Buffer  regulatory  minimum  ratio  will  be  phased  in  over  four
years starting in 2016 with minimum requirement of 0.625%
until fully phased in for fiscal year 2019 at 2.5%.

The  Company  and  NBT  Bank’s  actual  capital  amounts
and ratios are presented as follows as of December 31, 2016
and 2015:

options outstanding for the years ended December 31, 2016,
2015, and 2014, respectively, that were not considered in the

calculation  of  diluted  EPS  since  the  stock  options’  exercise
prices  were  greater  than  the  average  market  price  during
these periods.

(19)  Commitments and Contingent Liabilities

The  Company’s  concentrations  of  credit  risk  are  reflected
in the consolidated balance sheets. The concentrations of credit
risk with standby letters of credit, unused lines of credit, com-
mitments to originate new loans and loans sold with recourse
generally follow the loan classifications.

At December 31, 2016, approximately 59% of the Company’s
loans were secured by real estate located in central and upstate
New York, northeastern Pennsylvania, western Massachusetts,
southern New Hampshire, and Vermont. Accordingly, the ulti-
mate collectability of a substantial portion of the Company’s
portfolio  is  susceptible  to  changes  in  market  conditions  of
those areas. Management is not aware of any material concen-
trations of credit to any industry or individual borrowers.

The Company is a party to certain financial instruments with
off-balance sheet risk in the normal course of business to meet
the financing needs of its customers. These financial instruments
include commitments to extend credit, unused lines of credit,
standby letters of credit, and certain mortgage loans sold to
investors with recourse. The Company’s exposure to credit loss
in the event of nonperformance by the other party to the com-
mitments  to  extend  credit,  unused  lines  of  credit,  standby
letters  of  credit,  and  loans  sold  with  recourse  is  represented
by  the  contractual  amount  of  those  instruments. The  credit
risk associated with commitments to extend credit and standby
and commercial letters of credit is essentially the same as that
involved with extending loans to customers and is subject to
normal  credit  policies.  Collateral  may  be  obtained  based  on
management’s assessment of the customer’s creditworthiness.

                                                                                                                                                                                                                       At December 31,

being  funded  in  whole  or  in  part,  the  contract  amounts  are
not necessarily indicative of future cash flows. The Company
does  not  issue  any  guarantees  that  would  require  liability-
recognition or disclosure, other than its standby letters of credit.
The Company guarantees the obligations or performance
of customers by issuing standby letters of credit to third parties.
These standby letters of credit are frequently issued in support
of third party debt, such as corporate debt issuances, industrial
revenue bonds, and municipal securities. The risk involved in
issuing standby letters of credit is essentially the same as the
credit  risk  involved  in  extending  loan  facilities  to  customers,
and letters of credit are subject to the same credit origination,
portfolio maintenance and management procedures in effect
to monitor other credit and off-balance sheet products. Typically,

these instruments have terms of five years or less and expire
unused; therefore, the total amounts do not necessarily repre-
sent future cash requirements. The fair value of the Company’s
standby letters of credit at December 31, 2016 and 2015 was
not significant.

In the normal course of business there are various outstand-
ing  legal  proceedings.  If  legal  costs  are  deemed  material  by
management, the Company accrues for the estimated loss from
a loss contingency if the information available indicates that
it is probable that a liability had been incurred at the date of
the financial statements, and the amount of loss can be rea-
sonably estimated.

The Company is required to maintain reserve balances with
the FRB. The required average total reserve for NBT Bank for
the  14-day  maintenance  period  ending  December  21,  2016
was $56.2 million.

(20)  Derivative Instruments and Hedging Activities

The Company is exposed to certain risks arising from both
its business operations and economic conditions. The Company
principally manages its exposures to a wide variety of business
and operational risks through management of its core business
activities. The  Company  manages  economic  risks,  including
interest rate, primarily by managing the amount, sources, and
duration  of  its  assets  and  liabilities,  and  through  the  use  of
derivative instruments. Specifically, the Company enters into
derivative financial instruments to manage exposures that arise
from business activities that result in the receipt or payment
of  future  known  and  uncertain  cash  amounts,  the  value  of
which are determined by interest rates. The Company’s derivative
financial  instruments  are  used  to  manage  differences  in  the
amount,  timing,  and  duration  of  the  Company’s  known  or
expected cash receipts and its known or expected cash pay-
ments principally related to certain fixed rate borrowings. The
Company also has interest rate derivatives that result from a
service provided to certain qualifying customers and, therefore,
are  not  used  to  manage  interest  rate  risk  in  the  Company’s
assets  or  liabilities. The  Company  manages  a  matched  book
with respect to its derivative instruments in order to minimize
its net risk exposure resulting from such transactions.

Derivatives Not Designated 
as Hedging Instruments

The  Company  enters  into  interest  rate  swaps  to  facilitate
customer transactions and meet their financing needs. These
swaps  are  considered  derivatives,  but  are  not  designated  in
hedging  relationships. These  instruments  have  interest  rate
and credit risk associated with them. To mitigate the interest
rate risk, the Company enters into offsetting interest rate swaps

with counterparties. The counterparty swaps are also considered
derivatives and are also not designated in hedging relationships.
Interest rate swaps are recorded within other assets or other
liabilities on the consolidated balance sheet at their estimated
fair  value.  Changes  to  the  fair  value  of  assets  and  liabilities
arising from these derivatives are included, net, in other oper-
ating income in the consolidated statement of income.

The Company has two risk participation agreements with
financial institution counterparties for interest rate swaps related
to loans in which we are a participant. The risk participation
agreement provides credit protection to the financial institution
should the borrower fail to perform on its interest rate derivative
contract with the financial institution.

Derivatives Designated as Hedging Instruments

In 2016, the Company entered into interest rate swaps to
modify  the  interest  rate  characteristics  of  certain  short-term
FHLB advances from variable rate to fixed rate in order to reduce
the  impact  of  changes  in  future  cash  flows  due  to  market
interest rate changes. These agreements are designated as cash
flow hedges. Fair values included in other assets and other lia-
bilities on the consolidated balance sheet applicable to these
agreements amounted to $2.9 million and $0.2 million respec-
tively at December 31, 2016. For the year ended December 31,
2016  the  amount  included  in  other  comprehensive  income
totaled $1.8 million net of tax.

standing as well as the notional amount of risk participation
agreements as December 31:

(21)  Fair Values of Financial Instruments

GAAP states that fair value is an exit price, representing the
amount  that  would  be  received  to  sell  an  asset  or  paid  to
transfer  a  liability  in  an  orderly  transaction  between  market
participants.  Fair  value  measurements  are  not  adjusted  for
transaction costs. A fair value hierarchy exists within GAAP that
prioritizes the inputs to valuation techniques used to measure
fair value. The hierarchy gives the highest priority to unadjusted
quoted prices in active markets for identical assets or liabilities
(Level 1 measurements) and the lowest priority to unobservable
inputs (Level 3 measurements). The three levels of the fair value
hierarchy are described below:

Level 1—Unadjusted quoted prices in active markets that
are accessible at the measurement date for identical, unrestricted
assets or liabilities;

Level  2—Quoted  prices  for  similar  assets  or  liabilities  in
active markets, quoted prices in markets that are not active,
or inputs that are observable, either directly or indirectly, for
substantially the full term of the asset or liability;

Level 3—Prices or valuation techniques that require inputs
that  are  both  significant  to  the  fair  value  measurement  an
unobservable (i.e., supported by little or no market activity).

A financial instrument’s level within the fair value hierarchy
is based on the lowest level of input that is significant to the
fair value measurement.

The types of instruments valued based on quoted market
prices  in  active  markets  includes  most  U.S.  government  and
agency securities, many other sovereign government obligations,
liquid mortgage products, active listed equities and most money
market  securities.  Such  instruments  are  generally  classified

within Level 1 or Level 2 of the fair value hierarchy. The Company
does not adjust the quoted prices for such instruments.

The types of instruments valued based on quoted prices
in markets that are not active, broker or dealer quotations, or
alternative  pricing  sources  with  reasonable  levels  of  price
transparency include most investment-grade and high-yield
corporate  bonds,  less  liquid  mortgage  products,  less  liquid
agency securities, less liquid listed equities, state, municipal
and provincial obligations and certain physical commodities.
Such instruments are generally classified within Level 2 of the
fair value hierarchy.

Level 3 is for positions that are not traded in active markets
or are subject to transfer restrictions, valuations are adjusted
to reflect illiquidity and/or non-transferability and such adjust-
ments  are  generally  based  on  available  market  evidence.  In
the  absence  of  such  evidence,  management’s  best  estimate
will  be  used.  Management’s  best  estimate  consists  of  both
internal and external support on certain Level 3 investments.
Subsequent to inception, management only changes Level 3
inputs and assumptions when corroborated by evidence such
as transactions in similar instruments, completed or pending
third-party transactions in the underlying investment or com-
parable entities, subsequent rounds of financing, recapitaliza-
tions and other transactions across the capital structure, offerings
in the equity or debt markets and changes in financial ratios
or cash flows.

For the years ended December 31, 2016 and 2015, the Com-
pany  has  made  no  transfers  of  assets  between  Level  1  and
Level 2 or Level 3.

Certain common equity securities are reported at fair value
utilizing Level 1 inputs (exchange quoted prices). The majority
of  the  other  investment  securities  are  reported  at  fair  value
utilizing  Level  2  inputs. The  prices  for  these  instruments  are
obtained  through  an  independent  pricing  service  or  dealer
market participants with whom the Company has historically
transacted both purchases and sales of investment securities.
Prices  obtained  from  these  sources  include  prices  derived
from market quotations and matrix pricing. The fair value meas-
urements  consider  observable  data  that  may  include  dealer
quotes, market spreads, cash flows, the U.S. Treasury yield curve,

live  trading  levels,  trade  execution  data,  market  consensus
prepayment speeds, credit information, and the bond’s terms
and  conditions,  among  other  things.  Management  reviews
the methodologies used in pricing the securities by its third
party providers.

GAAP requires disclosure of assets and liabilities measured
and  recorded  at  fair  value  on  a  non-recurring  basis  such  as
goodwill,  loans  held  for  sale,  OREO,  collateral-dependent
impaired loans, mortgage servicing rights and held to maturity
securities.

The Company had collateral dependent impaired loans with
a  carrying  value  of  $7.0  million,  which  had  specific  reserves
included  in  the  allowance  for  loan  losses  of  $1.5  million  at
December 31, 2016. The Company uses the fair value of under-
lying collateral to estimate the specific reserves for collateral
dependent impaired loans. The fair value of underlying collateral
is generally determined through independent appraisals, which
generally include various Level 3 inputs which are not identifi-
able. The appraisals may be adjusted by management for qual-
itative  factors  such  as  economic  conditions  and  estimated
liquidation expenses ranging from 10% to 35%. Based on the

valuation  techniques  used,  the  fair  value  measurements  for
collateral dependent impaired loans are classified as Level 3.

The  following  table  sets  forth  information  with  regard  to
estimated fair values of financial instruments at December 31,
2016  and  December  31,  2015. This  table  excludes  financial
instruments for which the carrying amount approximates fair
value. Financial instruments for which the fair value approximates
carrying  value  include  cash  and  cash  equivalents,  securities
available for sale, trading securities, accrued interest receivable,
non-maturity deposits, short-term borrowings, accrued interest
payable, and interest rate swaps.

Fair  value  estimates  are  made  at  a  specific  point  in  time,
based on relevant market information and information about
the  financial  instrument. These  estimates  do  not  reflect  any
premium or discount that could result from offering for sale at
one time the Company’s entire holdings of a particular financial
instrument. Because no market exists for a significant portion
of  the  Company’s  financial  instruments,  fair  value  estimates
are based on judgments regarding future expected loss expe-
rience,  current  economic  conditions,  risk  characteristics  of
various financial instruments, 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  could  significantly
affect the estimates.

Fair value estimates are based on existing on and off-balance
sheet  financial  instruments  without  attempting  to  estimate
the value of anticipated future business and the value of assets
and  liabilities  that  are  not  considered  financial  instruments.
For example, the Company has a substantial trust and invest-
ment management operation that contributes net fee income
annually. The trust and investment management operation is
not  considered  a  financial  instrument,  and  its  value  has  not
been incorporated into the fair value estimates. Other significant
assets  and  liabilities  include  the  benefits  resulting  from  the
low-cost funding of deposit liabilities as compared to the cost

of borrowing funds in the market, and premises and equipment.
In addition, the tax ramifications related to the realization of
the  unrealized  gains  and  losses  can  have  a  significant  effect
on fair value estimates and have not been considered in the
estimate of fair value.

Fair values for securities are based on quoted market prices
or dealer quotes, where available. Where quoted market prices
are  not  available,  fair  values  are  based  on  quoted  market
prices of comparable instruments. When necessary, the Com-
pany utilizes matrix pricing from a third party pricing vendor
to  determine  fair  value  pricing.  Matrix  prices  are  based  on
quoted prices for securities with similar coupons, ratings, and
maturities, rather than on specific bids and offers for the des-
ignated security.

GAAP gives entities the option to measure eligible financial
assets, financial liabilities and Company commitments at fair
value (i.e., the fair value option), 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 rec-
ognizes a financial asset or financial liability or upon entering
into a Company commitment. Subsequent changes in fair value
must be recorded in earnings. As of December 31, 2016 and
2015, the Company did not elect the fair value option for any
eligible items.

Securities Held to Maturity

Long-Term Debt

The fair value of the Company’s investment securities held
to  maturity  is  primarily  measured  using  information  from  a
third party pricing service. The fair value measurements consider
observable data that may include dealer quotes, market spreads,
cash  flows,  the  U.S. Treasury  yield  curve,  live  trading  levels,
trade execution data, market consensus prepayment speeds,
credit information and the bond’s terms and conditions, among
other things.

Net Loans

The fair value of the Company’s loans was estimated by dis-
counting  the  expected  future  cash  flows  using  the  current
interest  rates  at  which  similar  loans  would  be  made  for  the
same  remaining  maturities.  Loans  were  first  segregated  by
type, and then further segmented into fixed and variable rate
and loan quality categories. Expected future cash flows were
projected based on contractual cash flows, adjusted for esti-
mated prepayments.

Time Deposits

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

The fair value of long-term debt was estimated using a dis-
counted  cash  flow  approach  that  applies  prevailing  market
interest rates for similar maturity instruments.

Junior Subordinated Debt

The fair value of trust preferred debentures has been esti-

mated using a discounted cash flow analysis.

Interest Rate Swaps

The  Company  enters  into  interest  rate  swaps  to  facilitate
customer transactions and meet their financing needs. These
swaps  are  considered  derivatives,  but  are  not  designated  in
hedging  relationships. These  instruments  have  interest  rate
and credit risk associated with them. To mitigate the interest
rate risk, the Company enters into offsetting interest rate swaps
with counterparties. The counterparty swaps are also considered
derivatives and are also not designated in hedging relationships.
Interest rate swaps are recorded within other assets or other
liabilities on the consolidated balance sheet at their estimated
fair  value.  Changes  to  the  fair  value  of  assets  and  liabilities
arising from these derivatives are included, net, in other oper-
ating income in the consolidated statement of income.

In 2016, the Company entered into interest rate swaps to
modify  the  interest  rate  characteristics  of  certain  short-term
FHLB advances from variable rate to fixed rate in order to reduce
the  impact  of  changes  in  future  cash  flows  due  to  market
interest rate changes. These agreements are designated as cash
flow hedges.

(22)  Sale of Equity Investment

On April 17, 2014, NBT Capital Corp., a wholly-owned sub-
sidiary of NBT, sold to LendingClub Corporation (“LendingClub”),
its  20%  ownership  interest  in  Springstone  Financial,  LLC
(“Springstone”),  which  NBT  originally  acquired  in  exchange
for a $3.0 million investment, as part of LendingClub’s acqui-
sition of all of the outstanding equity in Springstone. In total,
LendingClub paid the group of selling equity holders a purchase

price equal to $140.0 million in cash and preferred stock. As a
result  of  this  sale,  the  Company  recognized  a  gain  of  $19.4
million in 2014 and a gain of $4.2 million in 2015. There is $0.9
million in proceeds being held in escrow for indemnification
provisions of the sale contract which will be recognized into
income when the conditions of the contract have been deemed
to be satisfied.

(24)  Recent Accounting Pronouncements

In February 2017, the FASB issued Accounting Standards
Update (“ASU”) No. 2017-05, Other Income—Gains and Losses
from  the  Derecognition  of  Nonfinancial  Assets  (Subtopic  610-
20).  ASU  2017-05  will  clarify  the  scope  of  Subtopic  610-20
and add guidance for partial sales of nonfinancial assets. The
amendments define the term in substance nonfinancial assets,
and  clarify  that  a  nonfinancial  asset  within  the  scope  may
include nonfinancial assets transferred within a legal entity
to a counterparty, in part, as a financial asset promised to a
counterparty in a contract. Additionally, the amendments in
ASU clarify that an entity should identify each distinct nonfi-
nancial asset or in substance nonfinancial assets and allocate
consideration to each distinct asset. The amendments should
be  applied  either  retrospectively  to  each  period  presented
or  with  a  modified  retrospective  approach.  ASU  2017-05  is
effective for the Company on January 1, 2018 and the Company
is required to apply the amendment at the same time that it
applies  the  amendments  in  2014-09.  Early  adoption  is  per-
mitted but only as of annual reporting period beginning after
December 15, 2016. Management is evaluating the effect that
this guidance will have on the consolidated financial state-
ments and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Intangi-
bles—Goodwill and Other (Topic 350): Simplifying the Test for
Goodwill Impairment. ASU 2017-04 will amend and simplify the
subsequent measurement of goodwill, the amendments elim-
inate Step 2 from the goodwill impairment test. The amend-
ments also eliminate the requirements for any reporting unit
with a zero or negative carrying amount to perform Step 2 of
the goodwill impairment test. An entity still has the option to
perform the qualitative assessment for a reporting unit to deter-
mine if the qualitative impairment test is necessary. The amend-
ments should be applied on a prospective basis. The nature of
and reason for the change in accounting principle should be
disclosed upon transition. ASU 2017-04 is effective for the Com-
pany on January 1, 2020. Early adoption is permitted on testing
dates  after  January  1,  2017.  Management  is  evaluating  the
effect that this guidance will have on the consolidated financial
statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-01, Business
Combinations (Topic 805): Clarifying the Definition of a Business.
ASU 2017-01 provides a more robust framework to use in deter-
mining when a set of assets and activities (“set”) is a business
and to address stakeholder feedback that the definition of a
business in current GAAP is applied too broadly. The primary

amendments in the ASU provide a screen to exclude transactions
where substantially all of the fair value of the transferred set is
concentrated in a single asset, or group of similar assets, from
being evaluated as a business. ASU 2017-01 is effective for the
Company on January 1, 2018 using the prospective method.
Early  adoption  is  permitted.  Management  is  evaluating  the
effect that this guidance will have on the consolidated financial
statements and related disclosures.

In November 2016, the FASB issued ASU No. 2016-18, State-
ment of Cash Flows (Topic 230): Restricted Cash.  ASU  2016-18
address diversity in practice from entities classifying and pre-
senting transfers between cash and restricted cash as operating,
investing, or financing activities, or as a combination of those
activities  in  the  Statement  of  Cash  Flows. The  ASU  requires
entities to show the changes in the total of cash, cash equiva-
lents,  restricted  cash,  and  restricted  cash  equivalents  in  the
Statement of Cash Flows. As a result, transfers between such
categories  will  no  longer  be  presented  in  the  Statement  of
Cash Flows. ASU 2016-18 is effective for the Company on Jan-
uary 1, 2018 using the retrospective method. Early adoption
is permitted provided that all amendments are adopted in the
same  period.  Management  is  evaluating  the  effect  that  this
guidance will have on the consolidated financial statements
and related disclosures.

In  August  2016,  the  FASB  issued  Accounting  Standards
Update  (“ASU”)  No.  2016-15,  Statement of Cash Flows (Topic
230): Classification of Certain Cash Receipts and Cash Payments.
ASU 2016-15 addresses diversity in practice in how certain cash
receipts and cash payments are presented and classified in the
statement of cash flows. This standard addresses the following
eight specific cash flow issues: Debt prepayment or debt extin-
guishment costs; settlement of zero-coupon debt instruments
or other debt instruments with coupon interest rates that are
insignificant in relation to the effective interest rate of the bor-
rowing; contingent consideration payments made after a busi-
ness combination; proceeds from the settlement of insurance
claims; proceeds from the settlement of corporate-owned life
insurance policies; distributions received from equity method
investees; beneficial interests in securitization transactions; and
separately identifiable cash flows and application of the pre-
dominance principle. ASU 2016-15 is effective for the Company
on January 1, 2018. Early adoption is permitted, including adop-
tion in an interim period. Management is evaluating the effect
that this guidance will have on the consolidated financial state-
ments and related disclosures.

In June 2016, the FASB issued Accounting Standards Update
No.  2016-13,  Financial Instruments—Credit Losses (Topic 326):
Measurement of Credit Losses on Financial Instruments. ASU 2016-
13 requires the measurement of all expected credit losses for
financial assets held at the reporting date based on historical
experience, current conditions and reasonable and supportable
forecasts.  Financial  institutions  and  other  organizations  will
now  use  forward-looking  information  to  better  inform  their
credit loss estimates. Many of the loss estimation techniques
applied  today  will  still  be  permitted,  although  the  inputs  to
those  techniques  will  change  to  reflect  the  full  amount  of
expected credit losses. In addition, ASU 2016-16 amends the
accounting for credit losses on available for sale debt securities
and purchased financial assets with credit deterioration. ASU
2016-13 is effective for the Company on January 1, 2020. Early
adoption is permitted for all organizations for fiscal years and
interim periods within those fiscal years, beginning after Decem-
ber  15,  2019.  Management  is  evaluating  the  effect  that  this
guidance  will  have  on  the  consolidated  financial  statements
and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, Compen-
sation—Stock Compensation (Topic 718): Improvements to
Employee Share-Based Payment Accounting. ASU 2016-09 sim-
plifies the accounting for stock-based payment transactions,
including the income tax consequences, classification of awards
as either equity or liabilities and classification on the statement
of  cash  flows.  ASU  2016-09  is  effective  for  the  Company  on
January 1, 2017. Early adoption is permitted in any interim or
annual period. Management is evaluating the effect that this
guidance  will  have  on  the  consolidated  financial  statements
and related disclosures. Effective January 1, 2017, the Company
adopted ASU 2016-09. As a result of the adoption of this new
guidance, the Company made an accounting policy election
to account for forfeitures when they occur. The guidance was
required to be applied with a modified retrospective approach,
and, accordingly, the Company made a cumulative effect adjust-
ment recorded to opening retained earnings as of January 1,
2017 which was not material to the Company’s consolidated
financial statements.

In March 2016, the FASB issued ASU No. 2016-07, Invest-
ments—Equity Method and Joint Ventures (Topic 323): Simplifying
the Transition to the Equity Method of Accounting. ASU 2016-07
eliminates the requirement for an investor to adjust an equity
method investment, results of operations and retained earn-
ings  retroactively  on  a  step-by-step  basis  as  if  the  equity
method had been in effect during all previous periods that
the  investment  had  been  held  as  a  result  of  an  increase  in

the level of ownership interest or degree of influence. Addi-
tionally, an entity that has an available for sale equity security
that becomes qualified for the equity method of accounting
must recognize through earnings the unrealized holding gain
or loss in accumulated other comprehensive income at the
date the investment becomes qualified for use of the equity
method. ASU 2016-07 is effective for the Company on January
1, 2017. Early adoption is permitted in any interim or annual
period. Management does not believe the guidance will have
a  material  impact  on  the  consolidated  financial  statements
and related disclosures.

In March 2016, the FASB issued ASU No. 2016-06, Derivatives
and Hedging (Topic 815): Contingent Put and Call Options in Debt
Instruments. ASU 2016-06 clarifies the requirements for assessing
whether contingent call (put) options that can accelerate the
payment of principal on debt instruments are clearly and closely
related to their debt hosts. An entity performing the assessment
under the amendments in this Update is required to assess the
embedded call (put) options solely in accordance with the four-
step decision sequence. The amendments in this ASU clarify
what steps are required when assessing whether the economic
characteristics  and  risks  of  call  (put)  options  are  clearly  and
closely related to the economic characteristics and risks of their
debt hosts, which is one of the criteria for bifurcating an embed-
ded derivative. Consequently, when a call (put) option is con-
tingently exercisable, an entity does not have to assess whether
the event that triggers the ability to exercise a call (put) option
is related to interest rates or credit risks. The amendments are
an improvement to GAAP because they eliminate diversity in
practice in assessing embedded contingent call (put) options
in debt instruments. ASU 2016-07 is effective for the Company
on January 1, 2017. Early adoption is permitted in any interim
or annual period. Management does not believe this guidance
will have a material impact on the consolidated financial state-
ments and related disclosures.

In March 2016, the FASB issued ASU No. 2016-05, Derivatives
and Hedging (Topic 815): Effect of Derivative Contract Novations
on Existing Hedge Accounting Relationships. ASU 2016-05 clarifies
that a change in the counterparty to a derivative instrument
that has been designated as a hedging instrument does not
in  and  of  itself,  require  de-designation  of  that  hedging  rela-
tionship provided that all other hedge accounting criteria con-
tinue to be met. ASU 2016-05 is effective for the Company on
January 1, 2017. Early adoption is permitted in any interim or
annual  period.  Management  does  not  believe  this  guidance
will have a material impact on the consolidated financial state-
ments and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases
(Topic 842). ASU 2016-02 requires lessees to recognize right of
use assets and lease liabilities on the balance sheet for all leases
with terms longer than 12 months. For leases with a term of 12
months  or  less,  a  lessee  is  permitted  to  make  an  accounting
policy election by class of underlying asset not to recognize a
right of use asset and lease liability. Additionally, when measuring
assets  and  liabilities  arising  from  a  lease,  optional  payments
should be included only if the lessee is reasonable certain to
exercise  an  option  to  extend  the  lease,  exercise  a  purchase
option  or  not  exercise  an  option  to  terminate  the  lease.  ASU
2016-07 is effective for the Company on January 1, 2019. Early
adoption is permitted in any interim or annual period. Manage-
ment  is  evaluating  the  effect  that  this  guidance  will  have  on
the consolidated financial statements and related disclosures.
In January 2016, the FASB issued ASU No. 2016-01, Financial
Instruments—Overall  (Subtopic  825-10)—Recognition  and
Measurement of Financial Assets and Financial Liabilities. ASU
2016-01 addresses certain aspects of recognition, measure-
ment,  presentation  and  disclosure  of  financial  instruments
and requires entities to measure equity investments that do
not result in consolidation and are not accounted for under
the equity method at fair value. Any changes in fair value will
be recognized in net income unless the investments qualify
for a new practicability exception. This ASU also requires entities
to recognize changes in instrument-specific credit risk related
to financial liabilities measured under the fair value option in
other comprehensive income. No changes were made to the
guidance for classifying and measuring investments in debt
securities and loans. ASU 2016-01 is effective for the Company
on January 1, 2018. Early adoption is permitted in any interim
or  annual  period.  Management  is  evaluating  the  effect  that
this guidance will have on the consolidated financial statements
and related disclosures.

In  May  2014,  the  FASB  issued  ASU  No.  2014-09—Revenue
from Contracts with Customers (Topic 606).  ASU  2014-09  is  a
comprehensive  new  revenue  recognition  standard  that  will
supersede  nearly  all  existing  revenue  recognition  guidance
under GAAP and is based on the principle that revenue is rec-
ognized to depict the transfer of goods or services to customers
in an amount that reflects consideration to which the entity
expects to be entitled in exchange for those goods and services.
The ASU also requires additional disclosure about the nature,
amount,  timing  and  uncertainty  of  revenue  and  cash  flows
arising from customer contracts, including significant judgments
and changes in judgments and assets recognized from costs
incurred to obtain or fulfill a contract. For financial reporting
purposes, the standard allows for either full retrospective adop-
tion, meaning the standard is applied to all of the periods pre-
sented,  or  modified  retrospective  adoption,  meaning  the
standard is applied only to the most current period presented
in the financial statements with the cumulative effect of initially
applying the standard recognized at the date of initial appli-
cation. ASU 2014-09 was initially effective for the Company on
January 1, 2017; however, in August 2015, the FASB issued ASU
No. 2015-14—Revenue from Contracts with Customers—Deferral
of the Effective Date, which deferred the effective date to January
1, 2018. Early adoption is not permitted. In addition, the FASB
has begun to issue targeted updates to clarify specific imple-
mentation issues of ASU 2014-09. These updates include ASU
No. 2016-08—Principal versus Agent Considerations (Reporting
Revenue Gross versus Net),  ASU  No.  2016-10—Identifying Per-
formance Obligations and Licensing, ASU No. 2016-12—Narrow-
Scope Improvements and Practical Expedients,  and  ASU  No.
2016-20—Technical Corrections and Improvements to Top 606—
Revenue from Contract with Customers. Management is evaluating
the  effect  that  this  guidance  will  have  on  the  consolidated
financial statements and related disclosures.

ITEM 9A.  CONTROLS AND PROCEDURES

As of the end of the period covered by this Annual Report
on Form 10-K, an evaluation was carried out by the Company’s
management, with the participation of its Chief Executive Officer
and Chief Financial Officer, of the effectiveness of the Company’s
disclosure controls and procedures (as defined in Rule 13a-15(e)
under the Securities Exchange Act of 1934). Based upon that
evaluation, the Chief Executive Officer and Chief Financial Officer
concluded  that  the  disclosure  controls  and  procedures  were
effective as of the end of the period covered by this report. No
changes  were  made  to  the  Company’s  internal  control  over
financial reporting (as defined in Rule 13a-15(f) under the Secu-
rities Exchange Act of 1934) during the last fiscal quarter that
materially affected, or are reasonably likely to materially affect,
the Company’s internal control over financial reporting.

Management Report on Internal Controls 
Over Financial Reporting

The management of NBT Bancorp, Inc. (the “Company”) is
responsible for establishing and maintaining adequate internal
control over financial reporting. The Company’s internal control
over financial reporting is a process designed under the super-
vision of the Company’s Chief Executive Officer and Chief Finan-
cial  Officer  to  provide  reasonable  assurance  regarding  the

reliability of financial reporting and the preparation of the Com-
pany’s consolidated financial statements for external purposes
in accordance with generally accepted accounting principles.
As of December 31, 2016, management assessed the effec-
tiveness of the Company’s internal control over financial report-
ing  based  on  the  criteria  for  effective  internal  control  over
financial reporting established in “Internal Control—Integrated
Framework  (2013),”  issued  by  the  Committee  of  Sponsoring
Organizations (COSO) of the Treadway Commission. Based on
the assessment, management determined that the Company’s
internal  control  over  financial  reporting  as  of  December  31,
2016 was effective at the reasonable assurance level based on
those criteria.

KPMG  LLP,  the  independent  registered  public  accounting
firm that audited the consolidated financial statements of the
Company  included  in  this  Annual  Report  on  Form  10-K,  has
issued a report on the effectiveness of the Company’s internal
control over financial reporting as of December 31, 2016. The
report, which expresses an unqualified opinion on the effec-
tiveness of the Company’s internal control over financial report-
ing as of December 31, 2016, is included in this Item under the
heading “Report of Independent Registered Public Accounting
Firm” on the following page.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
NBT Bancorp Inc.:

We have audited NBT Bancorp, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December
31, 2016, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in
the accompanying Management 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,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of

December 31, 2016, based on the criteria established in Internal Control—Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States),
the  consolidated  balance  sheets  of  NBT  Bancorp  Inc.  and  subsidiaries  as  of  December  31,  2016  and  2015  and  the  related
consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows for each of the years
in the three-year period ended December 31, 2016, and our report dated March 1, 2017 expressed an unqualified opinion on
those financial statements.
