Dear Shareholders,

2020 was dominated by national news 
headlines—a 100-year pandemic, an energy 
industry downturn, near-zero interest rates and 
political uncertainty. This quartet of headwinds 
acted as the ultimate test of our business 
model, core values and the resiliency of our 
employees. I’m proud to say that we delivered 
a differentiated outcome on all fronts: 
for our customers, our employees, 
our shareholders and our communities.

In a year many have characterized as 
“worth forgetting,” BOK Financial Corporation, 
in my opinion, had a year that will be worth 
remembering.

Our Customers
Despite the challenges of conducting business almost wholly 
through virtual mediums, we stayed closely connected to 
customers. As a relationship-oriented institution, we saw the 
need for advice and counsel elevate substantially in all areas of 
our organization due to the extreme economic pressure brought 
by COVID-19. 

We were there for our business customers the day the Paycheck 
Protection Program went live on Friday, April 3. We redeployed 
more than 500 employees from many different areas of our 
company to help clients secure much-needed funding to keep 
their businesses and employee payrolls intact. In the end, we 
came together to help more than 5,000 customers receive over 
$2 billion in PPP funds. And we are poised to continue that 
assistance as new stimulus programs unfold in the new year. 

We helped evaluate investment portfolios and objectives with our 
many wealth management customers in light of extreme market 
volatility. As these clients sought ways to reduce risk and gain an 
advantage as market stability returned, we provided the crucial 
counsel sought in times of economic crisis. 

We also took swift action for our consumer banking customers, 
eliminating certain fees and loosening policies surrounding 
overdrafts. Additionally, quick access to forbearance relief for our 
mortgage customers provided financial flexibility and resiliency 
for families most impacted.

Our Employees
In mid-March, we swiftly undertook a massive initiative to 
move more than 75% of our employees to a work from home 
status. This involved a severe test of the many technology 
infrastructure and business resiliency investments we have 
made in the last several years. Candidly, it went better than we 
even anticipated. We quickly deployed a substantial inventory of 
laptops to employees who needed them, enabling us to maintain 
connectivity with customers and one another. For those critical 
employees who needed to stay on-site, we created proper 
cleaning and spacing protocol while using multiple sites where 
possible to reduce employee density. As part of the work from 
home process, we differentiated pay for the critical workforce 
and provided incremental funds for the technology needed at 
home for employees with school-age children. We also provided 
tutoring services and additional funds for employees to retain 
child care services for those who needed it. Our employee 
engagement’s defining characteristic was flexibility, as many were 
navigating unique challenges for themselves and their family.

Pandemic response aside, 2020 was also a year of advancing 
our commitment to building an even stronger and more 
diverse workforce in the second full year for our Diversity and 
Inclusion Council. We made great strides implementing an 
educational program focused on leveraging inclusion and 
mitigating unconscious bias for our employees, as well as a 
formal mentoring program as part of our talent development 
focus. We see a tremendous opportunity to gain greater diversity 
of thought and experience across our company as we see 
leadership transitions over the next 3-5 years in many vital areas. 
To address this, we continue to build a prepared slate of diverse 
candidates for those roles. In fact, we have made strides in 
increasing both the gender and racial diversity of our succession 
slates. Of note, this year we have doubled our percentage of 
internal female successor candidates for senior leadership team 
roles. We believe that a diverse workforce isn’t merely a desire; 
it’s necessary to drive business growth in the years ahead.

Our commitment to cultivate a diverse and inclusive workplace 
did not stop within our walls. In 2020, we signed the CEO 
Action for Diversity & Inclusion™ Pledge, the largest CEO-
driven business commitment to advance diversity and inclusion 
in the workplace. We are proud to join the more than 1,000 
CEOs of the world’s leading companies who have agreed to 
take action to cultivate a workplace where different points 
of view are welcomed, and employees feel encouraged to 
discuss challenging issues at work. I fully expect BOK Financial 
Corporation to be a leader in our industry and our communities 
when advancing diversity and inclusion efforts. There is still  
much work to do, but I am incredibly proud of the progress 
made in 2020.

Our Shareholders
We often discuss with our investors that we have intentionally 
built the bank to mitigate downside risk and earnings volatility. 
Remaining disciplined in our credit underwriting throughout the 
cycle and investing in growth for our fee-based businesses has 
been our company’s hallmark for decades.

That dual strategy was on full display in 2020 as we saw a 
precipitous drop in energy pricing, a key segment of our loan 
portfolio. Even though the economic outlook component of 
CECL drove a quick and significant increase to loan loss reserves 
in the first half of 2020, our asset quality has remained incredibly 
resilient. In fact, we expect to continue our outperformance 
related to charge-offs in our energy portfolio compared to peers 
in the space, while maintaining sub-historic charge-offs across all 
other lending functions.

The 150 basis points of emergency Federal Reserve rate cuts 
in March made the outlook for incremental quarterly earnings 
growth difficult for most banks. But having the ability to serve 
client needs across the spectrum of financial services is a 
competitive advantage for BOK Financial Corporation—and 
the income diversity rewards shareholders. Our fee income 
streams produced more than $800 million in revenue in 
2020, a testament to our resiliency during economic distress. 
Unprecedented demand due to the low rate environment and 
lack of industry capacity was a historic force that vaulted margins 
in our mortgage business to all-time highs. Our mortgage team 
produced record revenues in 2020, earning more than $180 
million for the company.

Additionally, our wealth management division put together a 
record revenue year with its host of complementary business 
units. We have considerable expertise related to mortgage 
backed securities trading and commodity hedging, and 
together, these two units increased revenue by a combined 
$67.9 million from 2019. Combined with significant deposit 
growth and growing investment management and investment 
banking revenue, our wealth management division is a diversified 
business within itself that provides stable shareholder value in 
both good times and bad. 

Despite the headwinds for the banking sector, our ability to 
generate revenue has never been more impressive with record 
annual pre-tax, pre-provision earnings of $786.4 million. 
Throughout 2020 we continued to accumulate capital and,  
once the immediate storm had passed, opportunistically bought 
back shares of our common equity to support EPS growth into 
the future. 

Our Communities
As the pandemic accelerated, so too did the deployment 
of our financial and employee volunteer resources to help 
those suffering most in the communities we serve. With a 
focus on organizations helping displaced workers from the 
hard-hit hospitality and restaurant industries, we embraced 
our leadership role in our communities by providing a record 
$6.8 million in funding to nonprofits serving critical needs. Our 
employees volunteered nearly 16,000 hours of their time and 
expertise, including 271 employees engaged in 465 meaningful 
leadership roles with organizations within our communities. As 
witnessed by our top ranking in the 2020 American Banker 
reputation survey, community engagement isn’t casual at BOKF; 
it’s a significant core value for all of our employees.

Like many across the country, we were outraged by the multiple 
incidents that resulted from income inequality and racial injustice 
that were only made worse by the disparate impact of the 
pandemic. We feel that it’s critical to back up our words with 
actions, so we have identified opportunities to address the root 

causes of income inequality and racial injustice by partnering 
with Tulsa and Dallas agencies focused on improving outcomes, 
especially in low to moderate income communities. Our focus 
has been to provide incremental funding and employee direct 
engagement to assist these agencies. As we monitor progress 
and outcome, we expect to broaden our focus to include all of 
the BOKF footprint markets. 

Our Future
2020 was a year that tested our core strengths and revealed 
our core values in a meaningful way. While the pandemic will 
ultimately be resolved through medical advancement, the impact 
on our company culture, our customer relationships, and our role 
in our communities will be forever changed—for the better.

Looking ahead, we remain optimistic about the resiliency of 
our customers and employees, and we expect upside growth 
across many of our business segments. We see a future that 
includes more robust digital capabilities, but also one where the 
value of a personal relationship with BOK Financial Corporation 
is significantly enhanced. The complexity of decision-making 
arising from the pandemic and its consequences has been a 
tremendous challenge for our customers. Like never before, 
we embrace our role as a foundation of experience, advice and 
counsel to create the best possible outcomes. This is a sweet 
spot for BOKF. Our operating model provides a credible and 
sustainable alternative to the national banks and investment firms 
that almost exclusively rely on technology to deliver impersonal, 
“in the box” solutions. While digital solutions are important 
for day to day transactional needs, we believe that having 
experienced, well-prepared and fully supported professionals to 
assist clients with their most meaningful decisions is critical to 
their success—as well as ours. 

As shareholders, we appreciate the confidence and trust you 
have placed in our company and our leadership team. We are 
grateful that you allow us to execute disciplined strategies that 
pay off in times of uncertainty, and you can see the fruits of that 
labor today. We pledge to keep the company firmly focused on 
long-term shareholder value and growth—while achieving that in 
tandem with a highly energized and committed workforce—and 
being a leader in the communities we serve. 2020 was a year like 
no other, but the growth story of BOK Financial Corporation has 
been enhanced from the challenges we have faced successfully.

Sincerely,

Steven G. Bradshaw 
President and Chief Executive Officer

PART I

General

Developments relating to individual aspects of the business of BOK Financial Corporation ("BOK Financial" or "the 
Company") are described below. Additional discussion of the Company’s activities during the current year appears within Item 
7 "Management’s Discussion and Analysis of Financial Condition and Results of Operations."

Description of Business

BOK Financial is a financial holding company incorporated in the state of Oklahoma in 1990 whose activities are governed by 
the Bank Holding Company Act of 1956 ("BHCA"), as amended by the Financial Services Modernization Act or Gramm-
Leach-Bliley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"). BOK 
Financial offers full service banking in Oklahoma, Texas, New Mexico, Northwest Arkansas, Colorado, Arizona, and Kansas/
Missouri. At December 31, 2020, the Company reported total consolidated assets of $47 billion.

BOKF, NA is a wholly owned subsidiary bank of BOK Financial. BOKF, NA operates TransFund, Cavanal Hill Investment 
Management and BOK Financial Asset Management, Inc. BOKF, NA operates banking divisions across eight states: Bank of 
Albuquerque, Bank of Oklahoma, Bank of Texas and BOK Financial in Arizona, Arkansas, Colorado, Kansas and Missouri; as 
well as having limited purpose offices in Nebraska, Wisconsin and Connecticut. Other wholly owned subsidiaries of BOK 
Financial include BOK Financial Securities, Inc., a broker/dealer that primarily engages in retail and institutional securities 
sales and municipal bond underwriting; BOK Financial Private Wealth, Inc., an investment adviser to high net worth clients; 
and BOK Financial Insurance, Inc., a broker providing insurance services. Other non-bank subsidiary operations do not have a 
significant effect on the Company’s financial statements. 

Our overall strategic objective is to emphasize growth in long-term value by building on our leadership position in Oklahoma 
through expansion into other high-growth markets in contiguous states. We operate primarily in the metropolitan areas of Tulsa 
and Oklahoma City, Oklahoma; Dallas, Fort Worth and Houston, Texas; Albuquerque, New Mexico; Denver, Colorado; 
Phoenix, Arizona, and Kansas City, Kansas/Missouri. Our acquisition strategy targets fairly priced quality organizations with 
demonstrated solid growth that would supplement our principal lines of business. We provide additional growth opportunities 
by hiring talent to enhance competitiveness, adding locations and broadening product offerings. Our operating philosophy 
embraces local decision-making in each of our geographic markets while adhering to common Company standards.

Our primary focus is to provide a comprehensive range of nationally competitive financial products and services in a 
personalized and responsive manner. Products and services include loans and deposits, cash management services, fiduciary 
and insurance services, mortgage banking and brokerage and trading services to middle-market businesses, financial institutions 
and consumers. Commercial banking represents a significant part of our business. Our credit culture emphasizes building 
relationships by making high quality loans and providing a full range of financial products and services to our customers. We 
offer derivative products that enable mortgage banking customers to manage their production risks and our energy financing 
expertise enables us to offer commodity derivatives for customers to use in their risk management. Our diversified base of 
revenue sources is designed to generate returns in a range of economic situations. Historically, fees and commissions provide 
39% to 48% of our total revenue. Approximately 42% of our revenue came from fees and commissions in 2020.

BOK Financial’s corporate headquarters is located at Bank of Oklahoma Tower, Boston Avenue at Second Street, Tulsa, 
Oklahoma 74172.

The Company’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and 
amendments to those reports are available on the Company’s website at www.bokf.com as soon as reasonably practicable after 
the Company electronically files such material with or furnishes it to the Securities and Exchange Commission.

Operating Segments

BOK Financial operates three principal lines of business: Commercial Banking, Consumer Banking and Wealth 
Management. Commercial Banking includes lending, treasury and cash management services and customer commodity risk 
management products for small businesses, middle market and larger commercial customers. Commercial Banking also 
includes the TransFund electronic funds network. Consumer Banking includes retail lending and deposit services, lending and 
deposit services to small business customers served through the retail branch network and all mortgage loan origination and 
servicing activities. Wealth Management engages in brokerage and trading activities, mainly related to providing liquidity to the 
mortgage markets through trading of  U.S. government agency mortgage-backed securities and related derivative contracts. 
Wealth Management also provides fiduciary services, private bank services, investment advisory services and insurance 
services in all markets. Additionally, Wealth Management underwrites state and municipal securities. Discussion of these 
principal lines of business appears within the Lines of Business section of "Management's Discussion and Analysis of Financial 
Condition and Results of Operations". 

Competition

BOK Financial and its operating segments face competition from other banks, thrifts, credit unions and other non-bank 
financial institutions, such as investment banking firms, investment advisory firms, brokerage firms, investment companies, 
financial technology firms, government agencies, mortgage brokers and insurance companies. The Company competes largely 
on the basis of customer services, interest rates on loans and deposits, lending limits and customer convenience. Some operating 
segments face competition from institutions that are not as closely regulated as banks, and therefore are not limited by the same 
capital requirements and other restrictions. All market share information presented below is based upon share of deposits in 
specified areas according to the Federal Deposit Insurance Corporation ("FDIC") as of June 30, 2020.

We are the largest financial institution in the state of Oklahoma with 16% of the state’s total deposits. We have 38% and 10% 
of the market share in the Tulsa and Oklahoma City areas, respectively. We compete with two banks that have operations 
nationwide and have greater access to funds at lower costs, higher lending limits, and greater access to technology resources. 
We also compete with regional and locally-owned banks in both the Tulsa and Oklahoma City areas, as well as in every other 
community in which we do business throughout the state.

We compete against numerous financial institutions in the state of Texas, including some of the largest in the United States, and 
have a market share of approximately 1% in the Dallas, Fort Worth area and less than 1% in the Houston area. We have an 11% 
market share in the Albuquerque area and compete with four large national banks, some regional banks and several locally-
owned smaller community banks. Our market share is approximately 4% in the Denver area. We serve Benton and Washington 
counties in Arkansas with a market share of approximately 2%. Our market share is approximately 1% in the Kansas City, 
Missouri/Kansas area. We operate as a community bank with locations in Phoenix, Mesa and Scottsdale with approximately 1% 
market share. The Company’s ability to expand into additional states remains subject to various federal and state laws.

Human Capital Management and Practices

In order to continue leading the financial industry as a provider of sophisticated solutions to businesses, institutions and 
individuals across the country, it is crucial that we attract, develop and retain top talent. To facilitate talent attraction and 
retention, we strive to make BOK Financial an inclusive workplace with opportunities for our employees to grow and develop 
in their careers. We support our employees with strong compensation, benefits, and wellness programs. We also work to build 
connections between our employees and our communities. “Actively advancing the communities we serve” is one of our core 
values. Those familiar with BOK Financial will recognize the generosity of our employees in our communities as one of the 
hallmarks of our culture, and a source of pride as we live out our purpose statement of “Achieving More Together”.

As of December 31, 2020, BOK Financial and its subsidiaries employed approximately 4,915 full-time and part-time 
employees, the majority of which are full-time employees. None of the Company’s employees are represented by collective 
bargaining agreements. Management considers its employee relations to be good. Our employees are distributed over our eight 
state footprint, to include: Oklahoma, Texas, Arkansas, Kansas, Missouri, Colorado, New Mexico and Arizona. As of year-end 
2020, our voluntary turnover rate was 10.5%, well below the financial services industry benchmark of 14%+ for voluntary 
turnover.

2

Response to COVID-19

Related to the COVID-19 pandemic, we implemented protocols that we determined were in the best interest of our employees 
to ensure operational continuity and employee safety. We moved a majority of our employees to a work-from-home status and 
implemented additional safety measures for employees continuing critical on-site operations. In addition, we implemented 
enhanced compensation and benefits offerings for employees and their families throughout the year.

Diversity and Inclusion Efforts

We believe that our organization should reflect the diversity of the communities we serve. We also recognize that in order for a 
diverse workforce to thrive, we must prioritize inclusion efforts. The following categories represent areas of focus for Diversity 
& Inclusion: community engagement, senior leader engagement, Communities of Practice, diverse recruiting practices and 
education.

Community Engagement

In 2020, the company and our BOKF Foundation gave a combined $6.2 million to organizations making a difference 
in our communities. Our employees donated more than 12,000 volunteer hours and more than 250 employees served 
on 320 nonprofit boards. Over the past ten years, we have committed nearly $565 million in loan funding to support 
affordable housing projects and nearly $305 million in affordable housing investments.

Senior Leader Engagement

Our Diversity & Inclusion Council is led by our CEO and President, Steve Bradshaw, and includes other members of 
the executive leadership team, as well as senior leaders throughout our footprint. As an organization, we joined the 
‘CEO Action for Diversity and Inclusion’ Pledge. The pledge outlines our commitment to cultivating a trusting 
environment where all ideas are welcomed, and employees feel comfortable and empowered to have discussions about 
diversity and inclusion.

Mentorship Program

Our mentorship program launched in the fourth quarter of 2020. We believe that mentorship programs are a valuable 
tool for helping employees successfully shape their long-term career trajectory. Mentor matches are prioritized for 
availability for females and people of color.

Communities of Practice

Earlier this year, we introduced a concept called ‘Communities of Practice’ ("CoP") as a way for our organization to 
build inclusive groups to harness the collective power of diverse skills, styles, strengths and experiences – and leverage 
those strengths into advancing our business. Six groups connecting employees from different disciplines, markets and 
lines of business were launched in 2020. More CoPs are set to launch in 2021, to include: Advancing Minority Owned 
Businesses, Practicing Inclusion, and Diverse Recruiting Practices. Any person from across the organization can join 
any Community of Practice; these groups highlight our enterprise focus on inclusivity.

Diverse Recruiting Practices

All members of the recruiting team have completed the Alliance of Information & Referral Systems ("AIRS") 
Certified Diversity Recruiter certification as well as a custom-developed training program for BOKF talent and 
attraction specialists. University recruiting has been a focal point for our diversity efforts. Our 2020 class of interns 
and early career associates saw significant increases both in number of females and people of color.

Diversity Education

Unconscious bias education was introduced for all managers in order to provide tools to adjust automatic patterns of 
thinking related to hiring practices. At the beginning of 2020, we also introduced a partnership with a well-known 
learning vendor to ensure all employees across the company had equal access to development opportunities in a virtual 
setting. The concept of ‘inclusion’ is woven into many of the learning opportunities offered by our Talent and 
Organizational Development team; examples would include: ‘Communicating Across Generations’ and ‘Crucial 
Conversations’.

Benefits and Compensation Offerings

BOKF is committed to the health and wellness of our employees. We provide our employees and their families with access to a 
variety of flexible and convenient health and wellness programs. We encourage engagement in healthy behaviors and offer 
options, where possible, to customize benefits to meet the needs of employees and their families. We provide robust 
compensation and benefits programs to help meet the needs of our employees. In addition to base salaries, these programs may 
include incentive compensation, discretionary bonuses, equity, 401(k), health and wellness benefits, health savings and flexible 
spending accounts, paid time off, family leave, flexible work schedules, employee assistance programs, and tuition 
reimbursement.

Talent Development

Our talent development programs provide employees with the resources they need to achieve their career goals, build 
management skills and lead within BOKF. We provide ‘boot camps’ that support professional development. We have programs 
that prepare high-potential talent for the leadership roles of tomorrow.

Connecting with Our Communities

Since our employees are passionate about many causes, our corporate giving and volunteering programs support and encourage 
employees by engaging with those causes. Our employee-led giving program allows employees to nominate and vote for 
nonprofit organizations across our footprint to receive financial benefit from our Foundation. This year, over 2,100 employees 
nominated and voted on 212 nonprofit organizations to receive funding.

Supervision and Regulation

BOK Financial and its subsidiaries are subject to extensive regulations under federal and state laws. Both the scope of the laws 
and regulations and the intensity of the supervision to which our business is subject have increased in recent years. Regulatory 
enforcement and fines have also increased across the banking and financial services sector. Many of these changes have 
occurred as a result of the Dodd-Frank Act and its implementing regulations, most of which are now in place. These regulations 
and others are designed to promote safety and soundness, protect consumers and ensure the stability of the banking system as a 
whole. The purpose of these regulations is not necessarily to protect shareholders and creditors. As detailed below, these 
regulations require the Company and its subsidiaries to maintain certain capital balances and require the Company to provide 
financial support to its subsidiaries. These regulations may restrict the Company’s ability to diversify, to acquire other 
institutions and to pay dividends on its capital stock. These regulations also include requirements on certain programs and 
services offered to our customers, including restrictions on fees charged for certain services. The Company expects that its 
business will remain subject to extensive regulation and supervision. 

The following information summarizes certain existing laws and regulations that affect the Company’s operations. It does not 
summarize all provisions of these laws and regulations and does not include all laws and regulations that affect the Company 
presently or in the future.

General

As a financial holding company, BOK Financial is regulated under the BHCA and is subject to regular inspection, examination 
and supervision by the Board of Governors of the Federal Reserve System (the "Federal Reserve Board"). Under the BHCA, 
BOK Financial files quarterly reports and other information with the Federal Reserve Board.

BOKF, NA is organized as a national banking association under the National Banking Act, and is subject to regulation, 
supervision and examination by the Office of the Comptroller of the Currency (the "OCC"), the FDIC, the Federal Reserve 
Board, the Consumer Financial Protection Bureau ("CFPB") and other federal and state regulatory agencies. The OCC has 
primary supervisory responsibility for national banks and must approve certain corporate or structural changes, including 
changes in capitalization, payment of dividends, change of place of business, and establishment of a branch or operating 
subsidiary. The OCC performs examinations concerning safety and soundness, the quality of management and directors, 
information technology and compliance with applicable regulations. The National Banking Act authorizes the OCC to examine 
every national bank as often as necessary.

A financial holding company, and the companies under its control, are permitted to engage in activities considered "financial in 
nature" as defined by the BHCA, Gramm-Leach-Bliley Act and Federal Reserve Board interpretations. Activities that are 
"financial in nature" include securities underwriting and dealing, insurance underwriting, merchant banking, operating a 
mortgage company, performing certain data processing operations, servicing loans and other extensions of credit, providing 
investment and financial advice, owning and operating savings and loan associations, and leasing personal property on a full 
pay-out, non-operating basis. A financial holding company is required to notify the Federal Reserve Board within thirty days of 
engaging in new activities determined to be "financial in nature." BOK Financial is engaged in some of these activities and has 
notified the Federal Reserve Board.

In order for a financial holding company to commence any new activity permitted by the BHCA, each insured depository 
institution subsidiary of the financial holding company must be "well capitalized" and "well managed" and have received a 
rating of at least "satisfactory" in its most recent examination under the Community Reinvestment Act. A financial holding 
company and its depository institution subsidiaries are considered to be "well capitalized" if they meet the requirements 
discussed in the section captioned "Capital Adequacy and Prompt Corrective Action" which follows. A financial holding 
company and its depository institution subsidiaries are considered to be "well managed" if they receive a composite rating and 
management rating of at least "satisfactory" in their most recent examinations. If a financial holding company fails to meet 
these requirements, the Federal Reserve Board may impose limitations or conditions on the conduct of its activities and the 
company may not commence any new financial activities without prior approval.   

The BHCA requires the Federal Reserve Board’s prior approval for the direct or indirect acquisition of more than five percent 
of any class of voting stock of any non-affiliated bank. Under the Federal Bank Merger Act, the prior approval of the OCC is 
required for a national bank to merge with another bank or purchase the assets or assume the deposits of another bank. In 
reviewing applications seeking approval of merger and acquisition transactions, the bank regulatory authorities consider, among 
other things, the competitive effect and public benefits of the transactions, the capital position of the combined organization, the 
applicant’s performance record under the Community Reinvestment Act and fair housing laws and the effectiveness of the 
subject organizations in combating money laundering activities.

A financial holding company and its subsidiaries are prohibited under the BHCA from engaging in certain tie-in arrangements 
in connection with the provision of any credit, property or services. Thus, a subsidiary of a financial holding company may not 
extend credit, lease or sell property, furnish any services or fix or vary the consideration for these activities on the condition that 
(1) the customer obtain or provide additional credit, property or services from or to the financial holding company or any 
subsidiary thereof, or (2) the customer may not obtain some other credit, property or services from a competitor, except to the 
extent reasonable conditions are imposed to insure the soundness of credit extended.

The Company and other non-bank subsidiaries are also subject to other federal and state laws and regulations. For example, 
BOK Financial Securities, Inc. is regulated by the Securities and Exchange Commission ("SEC"), the Financial Industry 
Regulatory Authority ("FINRA"), the Federal Reserve Board, and state securities regulators. Such regulations generally include 
licensing of certain personnel, customer interactions, and trading operations. 

Volcker and Swap Rules

Title VI of the Dodd-Frank Act, commonly known as the Volcker Rule, prohibits the Company from (1) engaging in short-term 
proprietary trading for our own account, and (2) having certain ownership interests in or relationships with private equity or 
hedge funds. The fundamental prohibitions of the Volcker Rule apply to banking entities of any size, including the Company 
and its bank subsidiary. Trading activity remains largely unaffected by the Volcker Rule as most of our trading activity is 
exempted or excluded from the proprietary trading prohibitions.

Title VII of the Dodd-Frank Act, commonly known as the Swap Rule, subjects nearly all derivative transactions to the 
regulations of the Commodity Futures Trading Commission ("CFTC") or SEC. This includes registration, recordkeeping, 
reporting, capital, margin and business conduct requirements on swap dealers and major swap participants. Under CFTC and 
SEC rules, entities transacting in less than $8 billion in notional value of swaps over any 12 month period are exempt from the 
definition of and registration as a "swap dealer." The Company currently estimates that the nature and volume of its swaps 
activity will not require it to register as a swap dealer.

Enhanced Prudential Standards

The Dodd-Frank Act directed the Federal Reserve Board to monitor emerging risks to financial institutions and enacted 
enhanced supervision and prudential standards applicable to bank holding companies with consolidated assets of $50 billion 
or more and non-bank covered companies designated as systematically important to the Financial Stability Oversight Council 
(often referred to as systemically important financial institutions). The Dodd-Frank Act mandated that certain regulatory 
requirements applicable to systemically important financial institutions be more stringent than those applicable to other 
financial institutions.  

In February 2014, the Federal Reserve Board adopted rules to implement certain of these enhanced prudential standards. 
Beginning in 2015, the rules required publicly traded bank holding companies with $10 billion or more in total consolidated 
assets to establish risk committees and required bank holding companies with $50 billion or more in total consolidated assets 
to comply with enhanced capital, liquidity and overall risk management standards. In May 2018, the Economic Growth, 
Regulatory Relief and Consumer Protection Act ("Regulatory Relief Act") raised the threshold for systemically important 
financial institutions from $50 billion to $250 billion while providing the Federal Reserve with authority to establish 
incremental prudential standards for banks between $100 billion and $250 billion.

Consumer Financial Protection

We  are  subject  to  a  number  of  federal  and  state  consumer  protection  laws  that  extensively  govern  our  relationship  with  our 
customers. These laws include the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth in Lending Act, the 
Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Home Mortgage Disclosure 
Act,  the  Fair  Housing  Act,  the  Real  Estate  Settlement  Procedures  Act,  the  Fair  Debt  Collection  Practices  Act,  the  Service 
Members  Civil  Relief  Act  and  these  laws’  respective  state-law  counterparts,  as  well  as  state  usury  laws  and  laws  regarding 
unfair  and  deceptive  acts  and  practices.  These  and  other  federal  laws,  among  other  things,  require  disclosures  of  the  cost  of 
credit  and  terms  of  deposit  accounts,  provide  substantive  consumer  rights,  prohibit  discrimination  in  credit  transactions, 
regulate  the  use  of  credit  report  information,  provide  financial  privacy  protections,  prohibit  unfair,  deceptive  and  abusive 
practices,  restrict  our  ability  to  raise  interest  rates  and  subject  us  to  substantial  regulatory  oversight.  Violations  of  applicable 
consumer  protection  laws  can  result  in  significant  potential  liability  from  litigation  brought  by  customers,  including  actual 
damages, restitution and attorneys’ fees. Federal bank regulators, state attorneys general and state and local consumer protection 
agencies may also seek to enforce consumer protection requirements and obtain these and other remedies, including regulatory 
sanctions, customer rescission rights, action by the state and local attorneys general in each jurisdiction in which we operate and 
civil money penalties. Failure to comply with consumer protection requirements may also damage our reputation and result in 
our failure to obtain any required bank regulatory approval for merger or acquisition transactions we may wish to pursue or our 
prohibition from engaging in such transactions even if approval is not required.

The  CFPB  has  broad  rulemaking  authority  for  a  wide  range  of  consumer  financial  laws  that  apply  to  all  banks,  including, 
among  other  things,  the  authority  to  prohibit  “unfair,  deceptive  or  abusive”  acts  and  practices.  Abusive  acts  or  practices  are 
defined as those that materially interfere with a consumer’s ability to understand a term or condition of a consumer financial 
product or service or take unreasonable advantage of a consumer’s (i) lack of financial savvy, (ii) inability to protect himself in 
the  selection  or  use  of  consumer  financial  products  or  services,  or  (iii)  reasonable  reliance  on  a  covered  entity  to  act  in  the 
consumer’s  interests.  The  CFPB  can  issue  cease-and-desist  orders  against  banks  and  other  entities  that  violate  consumer 
financial laws. The CFPB may also institute a civil action against an entity in violation of federal consumer financial law in 
order to impose a civil penalty or injunction. 

Community Reinvestment Act

The  Community  Reinvestment  Act  of  1977  ("CRA")  requires  depository  institutions  to  assist  in  meeting  the  credit  needs  of 
their market areas consistent with safe and sound banking practice. Under the CRA, each depository institution is required to 
help meet the credit needs of its market areas by, among other things, providing credit to low- and moderate-income individuals 
and communities. Depository institutions are periodically examined for compliance with the CRA and are assigned ratings. In 
order  for  a  financial  holding  company  to  commence  any  new  activity  permitted  by  the  BHCA,  or  to  acquire  any  company 
engaged  in  any  new  activity  permitted  by  the  BHCA,  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  CRA.  Furthermore, 
banking regulators take into account CRA ratings when considering a request for an approval of a proposed transaction. BOKF, 
NA received a rating of "outstanding" in its most recent CRA examination, which is above "satisfactory."

6

Financial Privacy

The federal banking regulators adopted rules that limit the ability of banks and other financial institutions to disclose non-public 
information about consumers to non-affiliated third parties. These limitations require disclosure of privacy policies to 
consumers and, in some circumstances, allow consumers to prevent disclosure of certain personal information to a non-
affiliated third party. These regulations affect how consumer information is transmitted through diversified financial companies 
and is conveyed to outside parties.

Capital Adequacy and Prompt Corrective Action

The Federal Reserve Board, the OCC and the FDIC have issued substantially similar risk-based and leverage capital guidelines 
applicable to United States banking organizations to ensure capital adequacy based upon the risk levels of assets and off-
balance sheet financial instruments. In addition, these regulatory agencies may from time to time require that a banking 
organization maintain capital above the minimum levels, whether because of its financial condition or actual or anticipated 
growth. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, 
liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and 
classifications are also subject to qualitative judgments by regulators regarding components, risk weighting and other factors.  

Federal Reserve Board risk-based guidelines define four capital metrics based on three categories of regulatory capital. 
Common equity Tier 1 capital ("CET1") includes common shareholders' equity, less goodwill, most intangible assets and other 
adjustments. Tier 1 capital consists of CET1 capital plus certain additional capital instruments and related surplus. 
Supplementary capital ("Tier 2") consists of preferred stock not qualifying as Tier 1 capital, qualifying mandatory convertible 
debt securities, limited amounts of subordinated debt, other qualifying term debt and allowances for credit losses, subject to 
limitations. Assets and off-balance sheet exposures are assigned to categories of risk-weights, based primarily upon relative 
credit risk. Risk-based capital ratios are calculated by dividing CET1, Tier 1 and total capital by risk-weighted assets. In 
addition to the risk-based capital ratios, the Company is also subject to the leverage ratio. The leverage ratio is determined by 
dividing Tier 1 capital by adjusted average total assets.

Additional capital rules were effective for banks and bank holding companies, including BOK Financial, on January 1, 2015 as 
part of a package of regulatory reforms developed by the Basel Committee on Banking Supervision ("BCBS") to strengthen the 
regulation, supervision and risk management of the banking sector, commonly referred to as the Basel III framework. Several 
components, which had previously been deferred, were finalized in 2019. These have been implemented with no material 
capital impact. 

Failure to meet minimum capital requirements would be subject to regulatory restrictions on capital distributions (including but 
not limited to dividends and share repurchases) and executive bonus payments. 

The Federal Deposit Insurance Corporation Improvement Act of 1991 (the "FDICIA"), among other things, identifies five 
capital categories for insured depository institutions from well capitalized to critically under-capitalized and requires the 
respective federal regulatory agencies to implement systems for prompt corrective action for institutions failing to meet 
minimum capital requirements within such categories. FDICIA imposes progressively more restrictive covenants on operations, 
management and capital distributions, depending upon the category in which an institution is classified. The various regulatory 
agencies have adopted substantially similar regulations that define the five capital categories identified by FDICIA, using the 
total risk-based capital, Tier 1 risk-based capital and leverage capital ratios as the relevant capital measures. Such regulations 
establish various degrees of corrective action to be taken when an institution is considered under-capitalized.

Stress Testing 

The Regulatory Relief Act eliminated the requirement for periodic company run capital stress tests known as the Dodd-Frank 
Act Stress Test for banks with assets less than $250 billion. Although the mandate has been lifted, the Company still continues 
to perform capital stress testing on a regular basis. 

7

Executive and Incentive Compensation

Guidelines adopted by federal banking agencies prohibit excessive compensation as an unsafe and unsound practice and 
describe compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by 
an executive officer, employee, director or principal shareholder. The Federal Reserve Board has issued comprehensive 
guidance on incentive compensation intended to ensure that the incentive compensation policies do not undermine safety and 
soundness by encouraging excessive risk taking. This guidance covers all employees that have the ability to materially affect 
the risk profile of an organization, either individually or as part of a group, based on key principles that (i) incentives do not 
encourage risk-taking beyond the organization's ability to identify and manage risk, (ii) compensation arrangements are 
compatible with effective internal controls and risk management, and (iii) compensation arrangements are supported by strong 
corporate governance, including active and effective board oversight. Deficiencies in compensation practices may affect 
supervisory ratings and enforcement actions may be taken if incentive compensation arrangements pose a risk to safety and 
soundness.  

Deposit Insurance

Substantially all of the deposits held by the subsidiary banks are insured up to applicable limits by the Deposit Insurance Fund 
("DIF") of the FDIC and are subject to deposit insurance assessments to maintain the DIF. In 2011, the FDIC released a final 
rule to implement provisions of the Dodd-Frank Act that affect deposit insurance assessments. Among other things, the Dodd-
Frank Act raised the minimum Designated Reserve Ratio (DRR) from 1.15% to 1.35% of estimated insured deposits, removed 
the upper limit of the designated reserve ratio, required that the designated reserve ratio reach 1.35% by September 30, 2020, 
and required that the FDIC offset the effect of increasing the minimum designated reserve ratio on depository institutions with 
total assets of less than $10 billion. The Dodd-Frank Act provided the FDIC flexibility in implementation of the increase in the 
designated reserve ratio, but it ultimately resulted in increased deposit insurance costs to the Company. The Dodd-Frank Act 
also required that the FDIC redefine the assessment base to average consolidated assets minus average tangible equity. 

On September 30, 2018 the DRR rose above 1.35%. Accordingly, the surcharge for depository institutions with assets of greater 
than $10 billion ceased. On September 15, 2020, the FDIC Board of Directors waived the provision of the FDIC's assessment 
regulations requiring that the reserve ratio must be at least 1.35% for the FDIC to remit the full nominal value of an insured 
depository institution's remaining assessment credits. All remaining small bank credits were refunded on the September 30, 
2020 assessment invoice, ending the application of small bank credits.

Dividends

A key source of liquidity for BOK Financial is dividends from BOKF, NA, which is limited by various banking regulations to 
net profits, as defined, for the year plus retained profits for the preceding two years. Dividends are further restricted by 
minimum capital requirements and the Company's internal capital policy. BOKF, NA's dividend limitations are discussed under 
the heading "Liquidity and Capital" within "Management's Discussion and Analysis of Financial Condition and Results of 
Operations."

Source of Strength Doctrine

According to Federal Reserve Board policy, a bank holding company is expected to act as a source of financial strength to each 
subsidiary bank and to commit resources to support each such subsidiary. This support may be required at times when a bank 
holding company may not be able to provide such support. 

Transactions with Affiliates

The Federal Reserve Board regulates transactions between the Company and its subsidiaries. Generally, the Federal Reserve 
Act and Regulation W, as amended by the Dodd-Frank Act, limit the Company’s banking subsidiary and its subsidiaries, to 
lending and other "covered transactions" with affiliates. The aggregate amount of covered transactions a banking subsidiary or 
its subsidiaries may enter into with an affiliate may not exceed 10% of the capital stock and surplus of the banking subsidiary. 
The aggregate amount of covered transactions with all affiliates may not exceed 20% of the capital stock and surplus of the 
banking subsidiary.

8

 
Covered transactions with affiliates are also subject to collateral requirements and must be conducted on arm’s length 
terms. Covered transactions include (a) a loan or extension of credit by the banking subsidiary, including derivative contracts, 
(b) a purchase of securities issued to a banking subsidiary, (c) a purchase of assets by the banking subsidiary unless otherwise 
exempted by the Federal Reserve, (d) acceptance of securities issued by an affiliate to the banking subsidiary as collateral for a 
loan, and (e) the issuance of a guarantee, acceptance or letter of credit by the banking subsidiary on behalf of an affiliate. 

Bank Secrecy Act and USA PATRIOT Act

The Bank Secrecy Act ("BSA") and The USA PATRIOT Act of 2001 ("PATRIOT Act") impose many requirements on 
financial institutions in the interest of national security and law enforcement. BSA requires banks to maintain records and file 
suspicious activity reports that are of use to law enforcement and regulators in combating money laundering and other financial 
crimes. The PATRIOT Act is intended to deny terrorists and criminals the ability to access the U.S. financial services system 
and places significantly greater requirements on financial institutions. Financial institutions, such as the Company and its 
subsidiaries, must have a designated BSA Officer, internal controls, independent testing and training programs commensurate 
with their size and risk profile. As part of its internal control program, a financial institution is expected to have effective 
customer due diligence and enhanced due diligence requirements for high-risk customers, as well as processes to prohibit 
transactions with entities subject to Office of Foreign Asset Control sanctions. Documentation and recordkeeping requirements, 
as well as system requirements, aimed at identifying and reporting suspicious activity reporting, must increase with the 
institution's size and complexity. Failure to implement or maintain adequate programs and controls to combat terrorist financing 
and money laundering may have serious legal, financial, and reputational consequences.

Governmental Policies and Economic Factors

The operations of BOK Financial and its subsidiaries are affected by legislative changes and by the policies of various 
regulatory authorities and, in particular, the policies of the Federal Reserve Board. The Federal Reserve Board has statutory 
objectives to maximize employment and maintain price stability. Among the instruments of monetary policy used by the 
Federal Reserve Board to implement these objectives are: open-market operations in U.S. Government securities, changes in the 
discount rate and federal funds rate on bank borrowings, and changes in reserve requirements on bank deposits. The effect of 
future changes in such policies on the business and earnings of BOK Financial and its subsidiaries is uncertain.

The spread of COVID-19 and related economic shutdowns that occurred during 2020 resulted in significant economic 
instability. In response, Congress and the Federal Reserve took aggressive actions. Congress passed an emergency $2.2 trillion 
relief package, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"), designed to alleviate some of the 
worst effects of the swift economic downturn. The Federal Reserve lowered the federal funds rate by 150 basis points to near 
zero and has initiated additional programs to infuse liquidity and stimulate economic activity. The Federal Reserve increased its 
purchasing position, purchasing about $120 billion in securities a month in the final half of 2020. The Federal Open Market 
Committee is committed to keeping the federal funds rate at the current level until the labor market has recovered consistent 
with their assessment of maximum employment and inflation has risen to 2 percent, and is on track to exceed that for some 
time. In December, 2020, Congress passed an additional $900 billion in stimulus to the U.S. economy. The newest package 
included the extension of federal pandemic unemployment compensation, funds for healthcare and vaccination distributions, an 
extended stay on evictions, stimulus check for qualifying Americans, employee tax credits, additional Paycheck Protection 
Program relief, among other provisions. 

The drastic decline in economic conditions in March and April was partially offset by a steep incline in May and June and 
moderated in the subsequent months. Real GDP grew 33% in the third quarter and demand for durable goods increased to pre-
pandemic levels. The housing market completely bounced back due to continued low mortgage interest rates. See "Summary of 
Credit Loss Experience" section on Management's Discussion and Analysis for further discussion around our economic 
forecast.

BOK Financial does not engage in operations in foreign countries, nor does it lend to foreign governments.

ITEM 1A.   RISK FACTORS

BOK Financial Corporation and its subsidiaries could be adversely affected by risks and uncertainties that could have a material 
impact on its financial condition and results of operations, as well as on its common stock and other financial instruments. Risk 
factors which are significant to the Company include, but are not limited to:

General and Regulatory Risk Factors

Adverse factors could impact BOK Financial's ability to implement its operating strategy.

Although BOK Financial has developed an operating strategy, which it expects to result in continuing improved financial 
performance, BOK Financial cannot ensure that it will be successful in fulfilling this strategy or that this operating strategy will 
be successful. Achieving success is dependent upon a number of factors, many of which are beyond BOK Financial's direct 
control. Factors that may adversely affect BOK Financial's ability to implement its operating strategy include:

•
•
•
•
•
•
•
•
•

deterioration of BOK Financial's asset quality;
deterioration in general economic conditions, especially in BOK Financial's core markets;
inability to control BOK Financial's non-interest expenses;
inability to increase non-interest income;
inability to access capital;
decreases in net interest margins;
increases in competition;
a breach in the security of BOK Financial's systems and
adverse regulatory developments.

Substantial competition could adversely affect BOK Financial.

Banking is a competitive business. BOK Financial competes actively for loan, deposit and other financial services business in 
the southwest region of the United States. BOK Financial's competitors include a large number of small and large local and 
national banks, savings and loan associations, credit unions, trust companies, broker-dealers and underwriters, as well as many 
financial and non-financial firms that offer services similar to those of BOK Financial. Large national financial institutions have 
substantial capital, technology and marketing resources. Such large financial institutions may have greater access to capital at a 
lower cost than BOK Financial does, which may adversely affect BOK Financial's ability to compete effectively.

BOK Financial has expanded into markets outside of Oklahoma, where it competes with a large number of financial institutions 
that have an established customer base and greater market share than BOK Financial. With respect to some of its services, BOK 
Financial competes with non-bank companies that are not subject to regulation. The absence of regulatory requirements may 
give non-banks a competitive advantage.

The increasingly competitive environment is in part a result of changes in regulation, changes in technology and product 
delivery systems and the accelerating pace of consolidation among financial service providers. Our success depends on our 
ability to respond to the threats and opportunities of financial technology innovations. Developments in "fintech" and crypto-
currencies have the potential to disrupt the financial industry and change the way banks do business. Investment in new 
technology to stay competitive could result in significant costs and increased cybersecurity risk. Our success depends on our 
ability to adapt to the pace of the rapidly changing technological environment which is important to retention and acquisition of 
customers.  

Government regulations and political environment could adversely affect BOK Financial.

BOK Financial and BOKF, NA are subject to banking laws and regulations that limit the type of acquisitions and investments 
that we may make. In addition, certain permitted acquisitions and investments are subject to prior review and approval by 
banking regulators, including the Federal Reserve, OCC and FDIC. Banking regulators have broad discretion on whether to 
approve proposed acquisitions and investments. In deciding whether to approve a proposed acquisition, federal banking 
regulators will consider, among other things, the effect of the acquisition on competition; the convenience and needs of the 
communities to be served, including our record of compliance under the Community Reinvestment Act; and our effectiveness 
in combating money laundering. They will also consider our financial condition and our future prospects, including projected 
capital ratios and levels; the competence, experience, and integrity of our management; and our record of compliance with laws 
and regulations. 

10

 
Regulatory authorities may change their interpretation of these statutes and regulations, including the OCC, our primary 
regulator, and the CFPB, our regulator for certain designated consumer laws and regulations. Violations of laws and regulations 
could limit the growth potential of BOK Financial's businesses. We have made extensive investments in human and 
technological resources to address enhanced regulatory expectations, including investments in the areas of risk management, 
compliance, and capital planning. Political developments, including recent Federal executive and legislative changes, add 
additional uncertainty to the implementation, scope and timing of changes in the regulatory environment for the banking 
industry and for the broader economy. 

BOK Financial has a long-standing relationship with the energy industry and the local economies within BOKF's geographical 
footprint have a concentration in energy-related industries. The energy industry is facing increased pressure from investors and 
the government to mitigate greenhouse emissions, which could significantly increase costs, hinder financial results and shrink 
the industry.  

Our business, financial condition, liquidity and results of operations have been, and will likely continue to be, adversely 
affected by the COVID-19 pandemic. 

The Coronavirus Disease 2019 (“COVID-19”) pandemic has created economic and financial disruptions that have adversely 
affected, and are likely to continue to adversely affect, BOKF’s business, financial condition, liquidity and results of operations. 
The extent to which the COVID-19 pandemic will continue to affect our business, financial condition, liquidity and results of 
operations will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and 
duration of the pandemic, the continued effectiveness of our business continuity plan, the direct and indirect impact of the 
pandemic on our employees, customers, clients, counterparties and service providers, as well as other market participants, and 
the effectiveness of actions taken by governmental authorities and other third parties in response to the pandemic.

The spread of the COVID-19 virus and the resulting "Stay at Home" orders, travel restrictions, and closed schools and work 
places caused severe disruptions in the U.S. economy, which has in turn disrupted the business activities and operations of our 
customers, as well as our business and operations. The COVID-19 outbreak was first reported in Wuhan, Hubei Province, 
China in December 2019, and has resulted in millions of confirmed cases identified around the world, many in the U.S. As a 
result of the pandemic, many businesses were shut down or continue to be shut down, supply chains were interrupted, slowed, 
or rendered inoperable, and many individuals have become ill, quarantined, or otherwise unable to work and/or travel due to 
health reasons or governmental restrictions. While multiple vaccines have been developed, the timing of administration of the 
vaccines to the full population, number of people who will take the vaccines, and the efficacy on new variants of the virus 
remains unknown. 

Specific to our operations, we face the following risks:

•

•

•

•

The pandemic, combined with pre-existing factors, including, but not limited to, international trade disputes, inflation 
risks, and oil price volatility, could further destabilize the financial markets and markets in which the Company 
operates. The resulting impacts on consumers, including the sudden increase in the unemployment rate, could cause 
changes in consumer and business spending, borrowing needs, and saving habits, which will likely affect the demand 
for loans and other products or services the Company offers, as well as the creditworthiness of potential and current 
borrowers.

Governmental mandates forced shutdowns of many of our customers' and vendors' facilities. While some have 
reopened, others may extend for indefinite periods. This may cause customers, third-party service providers, and 
counterparties to be unable to meet existing payment or other obligations to the Company. 

The COVID-19 virus may have an adverse effect on customer deposits, the ability of our borrowers to satisfy their 
obligations, the demand for our loans or other products and services, or on financial markets, real estate markets, or 
economic growth, which could adversely affect our liquidity, financial condition and results of operations.

The Federal Reserve reduced the target federal funds rate to 0.00% to 0.25% on March 15, 2020 and announced a 
significant quantitative easing program in response to the economic downturn caused by COVID-19. These reductions, 
especially if prolonged, could adversely affect our net interest income and margins, the value of mortgage servicing 
rights, and our profitability. 

• Widespread outbreaks of the COVID-19 virus in our primary geographies could adversely affect our workforce 

resulting in serious health issues and absenteeism. Social distancing measures enacted for working employees such as 
working from home, working in different locations, and working different shifts could further disrupt the workforce 

11

and normal internal control environment. This could lead to the inability to adequately meet customer needs, maintain 
adequate financial controls and cybersecurity controls, and meet regulatory deadlines. 

•

The determination of the appropriate level of allowance for credit losses involves a high degree of subjectivity and 
requires management to make significant estimates of current expected credit losses. The COVID-19 pandemic and the 
unprecedented governmental response could make these subjective judgments even more difficult. The economic 
impact of the pandemic and government responses may have an adverse effect on current and forward prices for oil 
and natural gas, which could result in significant credit losses. The value of real estate and other collateral securing 
loans may also be adversely affected. 

As a result of the preceding and other risks, if the COVID-19 virus continues to spread and the response to contain the 
pandemic is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, and 
results of operations. These adverse impacts could lead to a material impairment of goodwill and other intangible assets 
assigned to our reporting units.

Credit Risk Factors

Adverse regional economic developments could negatively affect BOK Financial's business.

At December 31, 2020, loans to businesses and individuals with collateral primarily located in Texas represented approximately 
31% of the total loan portfolio, loans to businesses and individuals with collateral primarily located in Oklahoma represented 
approximately 17% of our total loan portfolio and loans to businesses and individuals with collateral primarily located in 
Colorado represented approximately 12% of our total loan portfolio. These geographic concentrations subject the loan portfolio 
to the general economic conditions within these areas. Poor economic conditions in Texas, Oklahoma, Colorado or other 
markets in the southwest region may cause BOK Financial to incur losses associated with higher default rates and decreased 
collateral values in BOK Financial's loan portfolio. A regional economic downturn could also adversely affect revenue from 
brokerage and trading activities, mortgage loan originations and other sources of fee-based revenue.

Extended oil and gas commodity price downturns could negatively affect BOK Financial customers.

At December 31, 2020, 15% of BOK Financial's total loan portfolio is comprised of loans to borrowers in the energy industry. 
The energy industry is historically cyclical and prolonged periods of low oil and gas commodity prices could negatively impact 
borrowers' ability to pay. In addition, the Company does business in several major oil and natural gas producing states including 
Oklahoma, Texas and Colorado. The economies of these states could be negatively impacted by prolonged periods of low oil 
and gas commodity prices resulting in increased credit migration to classified and nonaccruing categories, higher loan loss 
provisions and risk of credit losses from both energy borrowers and businesses and individuals in those regional economies.

Other adverse economic factors affecting particular industries could have a negative effect on BOK Financial customers 
and their ability to make payments to BOK Financial.

Certain industry-specific economic factors also affect BOK Financial. For example, BOK Financial's loan portfolio includes 
commercial real estate loans. A downturn in the real estate industry in general or in certain segments of the commercial real 
estate industry in the southwest region could also have an adverse effect on BOK Financial's operations. Regulatory changes in 
healthcare may negatively affect our customers. Legislation affecting reimbursement rates along with the continued transition to 
managed care in place of fee for service payments could affect their ability to pay.

Adverse global economic factors could have a negative effect on BOK Financial customers and counterparties.

Economic conditions globally could impact BOK Financial’s customers and counterparties with which we do business. The 
ongoing COVID-19 pandemic has affected economies around the world, the United Kingdom continues to work through issues 
regarding BREXIT, trade related issues remain between the United States and China, and tension exists amongst the United 
States and OPEC Plus countries, including Russia and countries in the Middle East, over oil production levels. We have no 
direct exposure to European sovereign debt and limited exposure to European and Chinese financial institutions. We have not 
identified any significant customer exposures to European sovereign debt, European financial institutions or Chinese financial 
institutions.

BOK Financial, its customers and counterparties may also be negatively affected by global events, such as natural disasters, and 
other external events beyond our control, including public health issues, terrorist attacks and acts of war. These global events 

12

may significantly affect long-term and short-term interest rates, energy prices, the value of financial assets and ultimately 
economic activity in our primary markets. The adverse effect of these events on the Company may include narrowing of the 
spread between interest income and interest expense, a reduction in fee income, an increase in credit losses and a decrease in 
demand for loans and other products and services.  

Liquidity and Interest Rate Risk Factors

Fluctuations in interest rates could adversely affect BOK Financial's business.

BOK Financial's business is highly sensitive to:

•

•
•
•

the monetary policies implemented by the Federal Reserve Board, including the discount rate on bank borrowings 
and changes in reserve requirements, which affect BOK Financial's ability to make loans and the interest rates we 
may charge;
changes in prevailing interest rates, due to the dependency of the subsidiary banks on interest income;
changes in depositor behavior;
open market operations in U.S. Government securities.

A significant increase in market interest rates, or the perception that an increase may occur, could adversely affect both BOK 
Financial's ability to originate new loans and BOK Financial's ability to grow. Conversely, a decrease in interest rates could 
result in acceleration in the payment of loans, including loans underlying BOK Financial's holdings of residential mortgage-
backed securities and termination of BOK Financial's mortgage servicing rights. In addition, changes in market interest rates, 
changes in the relationships between short-term and long-term market interest rates or changes in the relationships between 
different interest rate indices, could affect the interest rates charged on interest-earning assets differently than the interest rates 
paid on interest-bearing liabilities. This difference could result in an increase in interest expense relative to interest income, 
which would reduce the Company’s net interest revenue. In a rising interest rate environment, the composition of the deposit 
portfolio could shift resulting in a mix that is more sensitive to changes in interest rates than is the current mix. An increase in 
market interest rates also could adversely affect the ability of BOK Financial's floating-rate borrowers to meet their higher 
payment obligations. If this occurred, it could cause an increase in nonperforming assets and net charge-offs, which could 
adversely affect BOK Financial's business.

In 2017, the U.K. Financial Conduct Authority announced its lack of confidence in LIBOR as a market benchmark rate, and 
that it would no longer persuade or compel banks to submit to LIBOR after 2021. U.S. regulatory authorities voiced similar 
support for phasing out LIBOR. The Federal Reserve Bank of New York's Alternative Reference Rate Committee has 
recommended the Secured Overnight Financing Rate ("SOFR") as an alternative to LIBOR.

In November of 2020, the ICE Benchmark Administration (IBA), the FCA-regulated and authorized administrator of LIBOR, 
announced its intention to cease USD LIBOR for one-week and two-month tenors at the end of 2021, but extend the anticipated 
cessation date for the remaining USD LIBOR tenors to the end of June 2023. U.S. regulators released a joint inter-agency 
statement about their expectations that banks cease entering into new contracts that use USD LIBOR as a reference rate as soon 
as practicable and in any event by December 31, 2021. 

We have a significant number of loans, securities, derivative contracts, borrowings and other financial instruments with 
attributes that are either directly or indirectly dependent on LIBOR. Given these uncertainties, it is not possible at this time to 
determine the impact of the transition away from LIBOR on the valuations, pricing and operation of our financial instruments. 
However, the proposed extension of our primary LIBOR tenors to June of 2023 reduces our exposure to the LIBOR transition 
significantly, as a large portion of our legacy financial instruments that matured after 2021 will mature before June of 2023.

In order to be well prepared for the transition, the Company has established formal governance for the LIBOR transition, 
including a LIBOR Transition Working Group ("the Group") whose purpose is to guide the overall transition process for the 
Company. The Group is an internal, cross-functional team with representatives from all business lines, support and control 
functions, and legal counsel. Its responsibilities include, but are not limited to, monitoring industry developments; tracking 
direct and indirect exposures; developing and implementing remediation plans; and communication with internal and external 
stakeholders.

Key loan provisions have been modified so that new and renewed loans include LIBOR fallback language designed to ensure 
the smoothest possible transition from LIBOR to the new benchmark when such transition occurs. All existing financial 
contracts with direct exposure to LIBOR have been inventoried and are being tracked. Indirect exposures in the form of 
LIBOR-related systems, models, and processes have been inventoried, evaluated, and prioritized and remediation is underway.

Changes in mortgage interest rates could adversely affect mortgage banking operations along with mortgage servicing rights 
as well as BOK Financial's substantial holdings of residential mortgage-backed securities, and brokerage and trading 
revenue. 

BOK Financial derives a substantial amount of revenue from mortgage banking activities, the production and sale of mortgage 
loans and the servicing of mortgage loans. In addition, as part of BOK Financial's mortgage banking business, BOK Financial 
has substantial holdings of mortgage servicing rights. Revenue generated from the production and sale of mortgage loans is 
affected by mortgage interest rates and government policies related to economic stimulus and home ownership. Falling interest 
rates tend to increase mortgage lending activities and related revenue while rising interest rates have an opposite effect. 

Mortgage servicing revenue is a fee earned over the life of the related loan. However, mortgage servicing rights are assets that 
are carried at fair value which are very sensitive to numerous factors with the primary factor being changes in market interest 
rates. Falling interest rates tend to increase loan prepayments, which may lead to a decrease in the value of related servicing 
rights. We attempt to manage this risk by maintaining an active hedging program. The primary objective of the Company's 
hedging program is to provide an offset to changes in the fair value of these rights due to hedgeable risks, primarily changes in 
market interest rates. Due to numerous unhedgeable factors, hedging strategies may not offset all changes in the fair value of 
the asset. Such unhedgeable factors include, but are not limited to, changes in customer prepayment or delinquency behavior 
that is inconsistent with historical actual performance in a similar market environment; changes in the long-term or short-term 
primary/secondary mortgage spreads; and changes in survey-driven assumptions such as the cost of servicing and discount 
rates. 

We also hold a substantial portfolio of residential mortgage-backed securities issued by U.S. government agencies. The fair 
value of residential mortgage-backed securities is highly sensitive to changes in interest rates. A significant decrease in interest 
rates may lead mortgage holders to refinance the mortgages constituting the pool backing the securities, subjecting BOK 
Financial to a risk of prepayment and decreased return on investment due to subsequent reinvestment at lower interest rates. A 
significant decrease in interest rates may also accelerate premium amortization. Conversely, a significant increase in interest 
rates may cause mortgage holders to extend the term over which they repay their loans, which delays the Company’s 
opportunity to reinvest funds at higher rates. We mitigate this risk somewhat by investing principally in shorter duration 
mortgage products, which are less sensitive to changes in interest rates.

In addition, the Company actively engages in trading activities that provide U.S. government agency residential mortgage-
backed securities and related derivative instruments to our customers. Trading activities generate net interest revenue, trading 
revenue and customer hedging revenue. Trading revenue and customer hedging revenue varies in response to customer demand. 
The value of trading securities will increase in response to decreases in interest rates or decrease in response to increases in 
interest rates. We mitigate the market risk of holding trading securities through appropriate economic hedging techniques. 

Market disruptions could impact BOK Financial’s funding sources.

BOK Financial’s subsidiary bank may rely on other financial institutions and the Federal Home Loan Bank of Topeka as a 
significant source of funds. Our ability to fund loans, manage our interest rate risk and meet other obligations depends on funds 
borrowed from these sources. The inability to borrow funds at market interest rates could have a material adverse effect on our 
operations.

Operating Risk Factors

Dependence on technology increases cybersecurity, data privacy and technology failure risk.  

The Company is dependent on its technological ability to process, record and monitor a large number of customer transactions 
and store and protect a significant amount of sensitive customer information. Our customers’ use of our internet-based services, 
and our customer and regulatory expectations regarding operational and information security and reliability, have increased 
over time. We face compliance risks and costs relating to the data privacy laws existing in multiple jurisdictions. Congress and 
the legislatures of states in which we operate regularly consider legislation that would impose more stringent data privacy 
requirements, resulting in increased compliance costs.

Cybersecurity risks for financial institutions have increased significantly in recent years in part because of the proliferation of 
new technologies, the increased use of the internet and mobile technologies to conduct financial transactions, and the increased 
sophistication and ever changing cyberattack techniques used by organized crime, hackers, terrorists, hostile foreign 
governments and other external parties to obtain confidential customer information and misappropriate customer funds. Such 
parties may seek to gain access to our systems directly or use equipment or security passwords belonging to employees, 

14

customers, third party services providers or other users of our systems. Accordingly, our operational systems and infrastructure 
must continue to be safeguarded and monitored for potential failures, disruptions, breakdowns and cyber attacks.  

Our business, financial, accounting, data processing systems and other operating systems and facilities may stop operating 
properly or become disabled as a result of a number of factors that may be wholly or partially beyond our control. In addition to 
cyber attacks, there could be sudden increases in customer transaction volume, electrical or telecommunications outages, 
natural disasters, pandemics, events arising from political or social matters, including terrorist attacks. Third parties with whom 
we do business or that facilitate our business activities including exchanges, clearing houses, financial intermediaries or vendors 
that provide services or security solutions for our operations, could also be sources of operational or information security risk to 
the Company, including breakdowns or failures of their own systems, capacity constraints or cyber attacks.

Cybersecurity risk management programs are expensive to maintain and will not protect the Company from all risks associated 
with maintaining the security of customer data from external and internal intrusions, disaster recovery and failures in controls 
used by our vendors. A material breach of customer data security or operational or system failure may negatively impact our 
business reputation and cause a loss of customers, result in increased expense to contain the event and/or require that we 
provide credit monitoring services for or reimburse affected customers, result in regulatory fines, penalties or intervention, or 
result in litigation, all of which could have a materially adverse effect on our results of operations and financial condition.

Although to date we have not experienced any material losses relating to cyber attacks or other information security breaches or 
operational failures, there can be no assurance that we will not suffer such losses in the future. Our risk and exposure to these 
matters remains heightened and as a result the continued development and enhancement of our controls, processes and practices 
designed to protect and facilitate the recovery of our systems, computers, software, data and networks from attack, damage or 
unauthorized access remains a high priority for us. As an additional layer of protection, we have purchased network and privacy 
liability risk insurance coverage. Our cybersecurity insurance may not provide sufficient coverage in the event of a breach, or 
may not be available in the future on acceptable terms. 

We depend on third parties for critical components of our infrastructure.

We outsource a significant portion of our information systems, communications, data management and transaction processing 
to third parties. These third parties are sources of risk associated with operational errors, system interruptions or breaches, 
unauthorized disclosure of confidential information and misuse of intellectual property. If the service providers encounter any 
of these issues, we could be exposed to disruption of service, reputation damages, and litigation risk that could be material to 
our business. 

Risks Related to an Investment in Our Stock

Although publicly traded, BOK Financial's common stock has substantially less liquidity than the average trading market 
for a stock quoted on the NASDAQ National Market System.

A relatively small fraction of BOK Financial's outstanding common stock is actively traded. The risks of low liquidity include 
increased volatility of the price of BOK Financial's common stock. Low liquidity may also limit holders of BOK Financial's 
common stock in their ability to sell or transfer BOK Financial's shares at the price, time and quantity desired.

BOK Financial's principal shareholder controls a majority of BOK Financial's common stock.

Mr. George B. Kaiser owns approximately 55% of the outstanding shares of BOK Financial's common stock at December 31, 
2020. Mr. Kaiser is able to elect all of BOK Financial's directors and effectively control the vote on all matters submitted to a 
vote of BOK Financial's common shareholders. Mr. Kaiser's ability to prevent an unsolicited bid for BOK Financial or any 
other change in control could have an adverse effect on the market price for BOK Financial's common stock. A substantial 
majority of BOK Financial's directors are not officers or employees of BOK Financial or any of its affiliates. However, because 
of Mr. Kaiser's control over the election of BOK Financial's directors, he could change the composition of BOK Financial's 
Board of Directors so that it would not have a majority of outside directors.

15

Possible future sales of shares by BOK Financial's principal shareholder could adversely affect the market price of BOK 
Financial's common stock.

Mr. Kaiser has the right to sell shares of BOK Financial's common stock in compliance with the federal securities laws at any 
time, or from time to time. The federal securities laws will be the only restrictions on Mr. Kaiser's ability to sell. Because of his 
current control of BOK Financial, Mr. Kaiser could sell large amounts of his shares of BOK Financial's common stock by 
causing BOK Financial to file a registration statement that would allow him to sell shares more easily. In addition, Mr. Kaiser 
could sell his shares of BOK Financial's common stock without registration under Rule 144 of the Securities Act. Although 
BOK Financial can make no predictions as to the effect, if any, that such sales would have on the market price of BOK 
Financial's common stock, sales of substantial amounts of BOK Financial's common stock, or the perception that such sales 
could occur, could adversely affect market prices. If Mr. Kaiser sells or transfers his shares of BOK Financial's common stock 
as a block, another person or entity could become BOK Financial's controlling shareholder.

Statutory restrictions on subsidiary dividends and other distributions and debts of BOK Financial's subsidiaries could limit 
amounts BOK Financial's subsidiaries may pay to BOK Financial.

A substantial portion of BOK Financial's cash flow typically comes from dividends paid by BOKF, NA. Statutory provisions 
and regulations restrict the amount of dividends BOKF, NA may pay to BOK Financial without regulatory approval. 
Management also developed, and the BOK Financial board of directors approved, an internal capital policy that is more 
restrictive than the regulatory capital standards. In the event of liquidation, creditors of the subsidiary banks and other non-bank 
subsidiaries of BOK Financial are entitled to receive distributions from the assets of that subsidiary before BOK Financial, as 
holder of an equity interest in the subsidiaries, is entitled to receive any distributions.

Management’s Assessment of Operations and Financial Condition

Overview

The following discussion is management’s analysis to assist in the understanding and evaluation of the financial condition and 
results of operations of BOK Financial Corporation ("BOK Financial" or "the Company"). This discussion should be read in 
conjunction with the Consolidated Financial Statements and footnotes and selected financial data presented elsewhere in this 
report.

After completing its 11th consecutive year of expansion in 2019, the U.S. economy experienced extreme volatility throughout 
2020. The worldwide spread of COVID-19 affected every part of the economic environment. Economic conditions in the U.S. 
declined drastically in March and April of 2020 following the initial U.S. COVID-19 outbreak. Congress quickly passed the 
CARES Act economic relief package, which alleviated some of the downturn. With the government stimulus package and some 
time to settle into the current new normal, the economy rebounded significantly in the second half of the year.

The Federal Reserve lowered the federal funds rate to near zero by April, 2020 and has initiated additional programs to infuse 
liquidity and stimulate economic activity. The Federal Reserve is expected to keep the federal funds rate at or near zero until the 
labor market has fully recovered and inflation has stabilized at 2%. See "Summary of Credit Loss Experience" section of 
Management's Discussion and Analysis for additional discussion around our economic forecast.

Performance Summary

Net income for the year ended December 31, 2020 totaled $435.0 million or $6.19 per diluted share compared with net income 
of $500.8 million or $7.03 per diluted share for the year ended December 31, 2019. A pre-tax provision for expected credit 
losses of $222.6 million was included in 2020 while a pre-tax provision for incurred losses of $44.0 million was included in 
2019. The Company adopted the current expected credit loss ("CECL") model on January 1, 2020. 

Pre-provision net revenue, a non-GAAP measure, was $786.4 million for 2020 compared to $674.9 million in the prior year. 
This is a measure of revenue less expenses, and is calculated before provision for credit losses and income tax expense. Pre-
provision net revenue is a financial measure frequently used by investors and analysts that enables them to assess a company's 
ability to generate earnings to cover credit losses through a credit cycle. It also provides an additional basis for comparing the 
results of operations between periods by isolating the impact of the provision for credit losses, which can vary significantly 
between periods.

We incurred $17.2 million of integration costs in 2019 related to the acquisition of CoBiz Financial, Inc. ("CoBiz") on October 
1, 2018, which resulted in an $0.18 per share reduction in 2019. The fluctuation discussion in the highlights below excludes this 
impact.

Highlights of 2020 included:

•

•

•

•

•

•

•

Net interest revenue totaled $1.1 billion for 2020, consistent with the prior year. Net interest margin was 2.83% for 
2020 compared to 3.11% for 2019. The Federal Reserve reduced the federal funds rate to near zero early in the year 
putting pressure on the margin in 2020. Average earning assets were $40.7 billion for 2020, up $4.3 billion over 2019. 
The  increase  was  largely  due  to  increased  trading  securities,  loans  primarily  related  to  the  Small  Business 
Administration's Paycheck Protection Program ("PPP"), and the expansion of the available for sale securities portfolio 
as we repositioned the balance sheet for a lower rate environment.

Fees and commissions revenue was $810.3 million for 2020, up $108.1 million compared to 2019. Mortgage banking 
revenue increased $74.8 million and brokerage and trading revenue increased $62.0 million. Lower mortgage interest 
rates increased both mortgage loan production and related trading activities. These increases were partially offset by a 
decrease in deposit service charges of $15.7 million and fiduciary and asset management revenue of $9.6 million.

Other operating expense totaled $1.2 billion, a $50.8 million increase compared to 2019. Personnel expense increased 
$30.8  million,  primarily  due  to  higher  incentive  compensation  expense  due  to  expanded  trading  activities.  This  was 
partially offset by lower employee benefits costs. Increased data processing and communications expense, occupancy 
and equipment expense, mortgage banking costs and charitable contributions were partially offset by lower business 
promotions expense. 

The net economic benefit of the changes in the fair value of mortgage servicing rights and related economic hedges 
was $24.9 million during 2020 compared to an economic cost of $17.9 million during 2019.

The  allowance  for  loan  losses  totaled  $389  million  or  1.69%  of  outstanding  loans  at  December  31,  2020.  The 
combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was 
$426 million or 1.85% of outstanding loans at December 31, 2020. Excluding PPP loans, which are fully guaranteed 
by  a  U.S.  government  agency,  the  allowance  for  loan  losses  was  1.82%  of  outstanding  loans  and  the  combined 
allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was 2.00%. 
The allowance for loan losses was $211 million or 0.97% of outstanding loans and the combined allowance for loan 
losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $212 million or 0.98% of 
outstanding loans at December 31, 2019.

Period-end outstanding loan balances were $23.0 billion at December 31, 2020, a $1.3 billion increase over the prior 
year, primarily due to the inflow of PPP loans. Average loans were $23.4 billion, a $1.3 billion increase compared to 
2019. 

Period-end deposits totaled $36.1 billion at December 31, 2020, an $8.5 billion increase compared to December 31, 
2019.  Interest-bearing  transaction  deposits  increased  $5.8  billion,  while  demand  deposit  balances  increased  $2.8 
billion. Average deposits increased $7.1 billion to $32.8 billion. Deposit growth was largely due to customers retaining 
higher  balances  in  the  current  economic  environment  combined  with  increases  due  to  various  COVID-19  related 
government program stimulus payments.

Common  equity  Tier  1  capital  ratio  was  11.95%  at  December  31,  2020.  In  addition,  the  Tier  1  capital  ratio  was 
11.95%, total capital ratio was 13.82% and leverage ratio was 8.28% at December 31, 2020. At December 31, 2019, 
the Tier 1 capital ratio was 11.39%, the total capital ratio was 12.94% and the leverage ratio was 8.40%.

The Company repurchased 1,107,100 shares at an average price of $68.49 per share during 2020 and 1,572,322 shares 
at an average price of $82.35 during 2019.

The Company paid cash dividends of $2.05 per common share during 2020 and $2.01 per common share in 2019. 

Net income for the fourth quarter of 2020 totaled $154.2 million or $2.21 per diluted share, compared to $110.4 million or 
$1.56 per diluted share for the fourth quarter of 2019. 

Highlights of the fourth quarter of 2020 included:

•

•

•

•

Net interest revenue totaled $297.2 million for the fourth quarter of 2020, an increase of $27.0 million compared to the 
fourth quarter of 2019, largely due to a $5.2 billion increase in average trading securities. We saw a shift from trading 
revenue to interest income on trading securities in the fourth quarter of 2020. Net interest margin was 2.72% for the 
fourth  quarter  of  2020  and  2.88%  for  the  fourth  quarter  of  2019.  The  increase  in  the  trading  securities  portfolio 
combined with the repricing of our available for sale securities portfolio decreased the net interest margin.  

Fees  and  commissions  revenue  totaled  $181.1  million,  up  $1.6  million  over  the  fourth  quarter  of  2019.  Increased 
mortgage banking revenue stemming from the low interest rate environment was largely offset by decreased brokerage 
and trading revenue, fiduciary and asset management revenue, and deposit service charges. 

Operating expenses in the fourth quarter totaled $300.7 million, an $11.9 million increase compared to the prior year. 
Personnel expense increased $7.8 million primarily due to higher incentive compensation expense, partially offset by 
regular  compensation  expense.  Non-personnel  expenses  increased  $4.1  million,  largely  due  to  increased  data 
processing  and  communications  expense  and  higher  charitable  contributions,  partially  offset  by  lower  business 
promotion expense.

Based on an evaluation of economic forecasts and loan portfolio characteristics, the Company recorded a $6.5 million 
negative provision for expected credit losses in the fourth quarter of 2020 and a $19.0 million provision for incurred 
credit losses in the fourth quarter of 2019.

Critical Accounting Policies & Estimates

The Consolidated Financial Statements and accompanying notes are prepared in accordance with generally accepted accounting 
principles in the United States of America (“GAAP”). The Company's accounting policies are more fully described in Note 1 of 
the Consolidated Financial Statements. Management makes significant assumptions and estimates in the preparation of the 
Consolidated Financial Statements and accompanying notes in conformity with GAAP that may be highly subjective, complex 
and subject to variability. Actual results could differ significantly from these assumptions and estimates. The following 
discussion addresses the most critical areas where these assumptions and estimates could affect the financial condition, results 
of operations and cash flows of the Company. These critical accounting policies and estimates have been discussed with the 
appropriate committees of the Board of Directors.

Allowance for Loan Losses and Accrual for Off-Balance Sheet Credit Risk from Loan Commitments

The allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments represent the 
portion of amortized cost basis of loans and related unfunded commitments we do not expect to collect over the asset’s 
contractual life, considering past events, current conditions, as well as reasonable and supportable forecasts of future economic 
conditions. Appropriateness of the allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan 
commitments is determined by a senior management Allowance Committee which requires judgment about effects of uncertain 
matters, resulting in a subjective calculation which is inherently imprecise. Because of the subjective forward-looking nature of 
the calculation, changes in these measures may not directly correlate with actual economic events. In future periods, 
management judgment may consider new or changed information which may cause significant changes in these allowances in 
those future periods.  

As of January 1, 2020 BOK Financial’s accounting policies have changed significantly with the adoption of Financial 
Accounting Standards Board ("FASB") Accounting Standards Update No. 2016-13 Financial Instruments - Credit Losses 
(Topic 326): Assets Measured at Amortized Cost ("ASU 2016-13" or "CECL"). Prior years are not restated. Prior to January 1, 
2020, general allowances and nonspecific allowances were based on incurred credit losses. See Note 4 to the Consolidated 
Financial Statements for the description of the expected credit losses calculation of the allowance for loan losses and accrual for 
off-balance sheet credit risk from unfunded loan commitments.  

For the majority of risk-graded loans, the accruing loan’s expected credit loss estimate is sensitive to management judgment, 
particularly probability of default and loss given default assumptions, changes in specific macroeconomic factor forecasts and 
the probability weight assigned to each economic scenario. 

Probability of default and loss given default measurements are based on historical data that may not be a good predictor of 
future performance or actual losses. Probability of default is based on risk grades, a subjective measurement of the risk of a 
loan. This subjective assessment of risk may not reflect actual risk of loss.

Other subjective measures include the forecast for each relevant economic loss driver and the probability weighting of 
economic scenarios, both of which are overseen by a senior management Economic Forecast Committee which includes 
members independent of the allowance process. The Allowance Committee may increase or decrease the allowance based on 
factors that include, for example, new lines of business, market conditions that have not been previously encountered, observed 
changes in credit risk that are not yet reflected in macroeconomic factors, or economic conditions that impact loss given default 
assumptions. 

Although the resulting expected credit loss estimate represents management’s best estimates at the time, actual credit losses will 
differ from management’s estimate. Portfolio composition will change over time, actual economic conditions will differ from 
probability-weighted assumptions, borrower-specific circumstances will change, as well as other factors. Differences between 
actual losses and management's estimates may materially affect the Company's results of operations. 

Fair Value Measurement

Certain assets and liabilities are recorded at fair value in the Consolidated Financial Statements. Fair value is defined by 
applicable accounting guidance as the price to sell an asset or transfer a liability in an orderly transaction between market 
participants in the principal markets for the given asset or liability at the measurement date based on market conditions at that 
date. An orderly transaction assumes exposure to the market for a customary period for marketing activities prior to the 
measurement date and not a forced liquidation or distressed sale.

25

A hierarchy for fair value has been established that prioritizes the inputs of valuation techniques used to measure fair value into 
three broad categories: unadjusted quoted prices in active markets for identical assets or liabilities (Level 1), other observable 
inputs that can be observed either directly or indirectly (Level 2) and unobservable inputs for assets or liabilities (Level 3). Fair 
value may be recorded for certain assets and liabilities every reporting period on a recurring basis or under certain 
circumstances on a non-recurring basis. Fair value measurements of significant assets or liabilities that are based on 
unobservable inputs (Level 3) are considered Critical Accounting Policies and Estimates. Additional discussion of fair value 
measurement and disclosure is included in Notes 7 and 19 of the Consolidated Financial Statements. 

Mortgage Servicing Rights

We have a significant investment in mortgage servicing rights. Our mortgage servicing rights are primarily retained 
from sales in the secondary market of residential mortgage loans we have originated or purchased from correspondent 
lenders. Occasionally, mortgage servicing rights may be purchased from other lenders. Both originated and purchased 
mortgage servicing rights are initially recognized at fair value. We carry all mortgage servicing rights at fair value. 
Changes in fair value are recognized in earnings as they occur.

Mortgage servicing rights are not traded in active markets. The fair value of mortgage servicing rights is determined by 
discounting the projected cash flows. Certain significant assumptions and estimates used in valuing mortgage servicing 
rights are based on current market sources including projected prepayment speeds, assumed servicing costs, earnings 
on escrow deposits, ancillary income and discount rates. Assumptions used to value our mortgage servicing rights are 
considered significant unobservable inputs and represent our best estimate of assumptions that market participants 
would use to value this asset. A separate third party model is used to estimate prepayment speeds based on interest 
rates, housing turnover rates, estimated loan curtailment, anticipated defaults and other relevant factors. The 
prepayment model is updated periodically for changes in market conditions and adjusted to better correlate with actual 
performance of our servicing portfolio. The discount rate is based on benchmark rates for mortgage loans plus a 
market spread expected by investors in servicing rights. Significant assumptions used to determine the fair value of our 
mortgage servicing rights are presented in Note 7 to the Consolidated Financial Statements. At least annually, we 
request estimates of fair value from outside sources to corroborate the results of the valuation model.

The assumptions used in this model are primarily based on mortgage interest rates. Evaluation of the effect of a change 
in one assumption without considering the effect of that change on other assumptions is not meaningful. Considering 
all related assumptions, we expect a 50 basis point increase in primary mortgage interest rates to increase the fair value 
of our servicing rights by $29 million. We expect a $15 million decrease in the fair value of our mortgage servicing 
rights from a 50 basis point decrease in primary mortgage interest rates.  

Valuation of Impaired Loans and Real Estate and Other Repossessed Assets

The fair value of collateral for certain impaired loans and real estate and other repossessed assets is measured on a 
non-recurring basis. The fair value of real estate is generally based on unadjusted third-party appraisals derived 
principally from or corroborated by observable market data. Fair value measurements based on these appraisals are 
considered to be based on Level 2 inputs. Fair value measurements based on appraisals that are not based on 
observable inputs or that require significant adjustments by us or fair value measurements that are not based on third-
party appraisals are considered to be based on Level 3 inputs. Significant unobservable inputs include listing prices for 
comparable assets, uncorroborated expert opinions or management's knowledge of the collateral or industry.

The fair value of mineral rights is generally determined by our internal staff of engineers based on projected cash flows 
from proven oil and gas reserves under existing economic and operating conditions. Proven oil and gas reserves are 
estimated quantities that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in 
future years from known reservoirs using existing prices and costs. Projected cash flows incorporate assumptions 
related to a number of factors including production, sales prices, operating expenses, severance, ad valorem taxes, 
capital costs and appropriate discount rate. Fair values determined through this process are considered to be based on 
Level 3 inputs.  

Income Taxes

Determination of income tax expense and related assets and liabilities is complex and requires estimates and judgments when 
applying tax laws, rules, regulations and interpretations. It also requires judgments as to future earnings and the timing of future 
events. Accrued income taxes represent an estimate of net amounts due to or from taxing jurisdictions based upon these 
estimates, interpretations and judgments.

26

 
Management evaluates the Company's current tax expense or benefit based upon estimates of taxable income, tax credits and 
statutory tax rates. Annually, we file tax returns with each jurisdiction where we conduct business and adjust recognized income 
tax expense or benefit to filed tax returns.

We recognize deferred tax assets and liabilities based upon the differences between the values of assets and liabilities as 
recognized in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the 
differences are expected to be recovered or settled. A valuation allowance is provided when it is more likely than not that some 
portion of the entire deferred tax asset may not be realized.  

We also recognize the benefit of uncertain tax positions when based upon all relevant evidence, it is more-likely-than-not that 
our position would prevail upon examination, including resolution of related appeals or litigation, based upon the technical 
merits of the position. Unrecognized tax benefits, including estimated interest and penalties, are part of our current accrued 
income tax liability. Estimated penalties and interest are recognized in income tax expense. Income tax expense in future 
periods may decrease if an uncertain tax position is favorably resolved, generally upon completion of an examination by the 
taxing authorities, expiration of a statute of limitations, or changes in facts and circumstances.

Goodwill Impairment

Goodwill for each reporting unit is evaluated for impairment annually as of October 1st or more frequently if conditions 
indicate that impairment may have occurred. The evaluation of possible goodwill impairment involves significant judgment 
based upon short-term and long-term projections of future performance. 

During the evaluation for impairment, management qualitatively assesses whether it is more likely than not that the fair value of 
the reporting units is less than their carrying value, including goodwill. Reporting unit carrying value includes sufficient capital 
to exceed regulatory requirements. This assessment includes consideration of relevant events and circumstances including, but 
not limited to, macroeconomic conditions, industry and market conditions, the financial and stock performance of the Company 
and other relevant factors. Specifically, the analysis may include:

•

•

•

•

•

•

General economic conditions including overall economic activity, consumer spending and mobility, unemployment 
rates, consumer confidence, and duration and severity of any current market moving instability.
Global health concerns including ongoing pandemics or potential for widespread health issues, the future course of a 
pandemic and the potential for medical advances.
Regional economic conditions including demand for oil and price stability of oil, other overarching conditions that 
may be affecting any of the Company's primary states such as weather or other catastrophes, pandemics and health 
related lockdowns, or other state mandates. 
Industry conditions including federal funds rate movement by the Federal Reserve, the interest rate environment and 
the resulting effect on net interest revenue and operating revenue, and regulatory mandates that hinder or provide relief 
to the financial services industry. 
Company specific conditions including current and forecasted income, changes in stock price, the Company's stock 
price compared to peers and other indexes, book value per share compared to fair value per share, goodwill compared 
to total shareholders' equity, current capital and liquidity position, demand for products and services, health of the loan 
portfolio and other credit related factors, and current credit ratings with the ratings agencies, and regulatory ratings.
Reporting unit performance and forecasts including any event that may significantly impact a reporting unit. 

If management concludes based on the qualitative assessment that goodwill may be impaired, a quantitative impairment test 
will be applied to goodwill at all reporting units. The quantitative analysis compares the fair value of the reporting unit with its 
carrying value, including goodwill. The fair value of each reporting unit is estimated by the discounted future earnings method. 
Goodwill is considered impaired if the fair value of the reporting unit is less than the carrying value of the reporting unit, 
including goodwill.

Both the qualitative assessment and quantitative analysis require significant management judgment, including estimates of 
changes in future economic conditions and their underlying causes and duration, the reasonableness and effectiveness of 
management's responses to those changes, changes in governmental fiscal and monetary policies, and fair value measurements 
based largely on significant unobservable inputs. The results of these judgments may have a significant impact on the 
Company's reported results of operations. 

See Note 6, "Goodwill and Intangible Assets" for breakout of goodwill by reporting unit.

Results of Operations

Net Interest Revenue and Net Interest Margin

Net interest revenue is the interest earned on debt securities, loans and other interest-earning assets less interest paid for 
interest-bearing deposits and other borrowings. The net interest margin is calculated by dividing tax-equivalent net interest 
revenue by average interest-earning assets. Net interest spread is the difference between the average rate earned on interest-
earning assets and the average rate paid on interest-bearing liabilities. Net interest margin is typically greater than net interest 
spread due to interest income earned on assets funded by non-interest bearing liabilities such as demand deposits and equity.

Tax-equivalent net interest revenue totaled $1.1 billion for 2020, consistent with the prior year. This includes $26.0 million of 
net purchase discount accretion for 2020 and $37.8 million for 2019. Approximately $48 million of purchase accounting 
discount remains to be accreted. Net interest revenue decreased $108.7 million due to changes in interest rates and increased 
$102.8 million from growth in earning assets. Table 2 shows the effects on net interest revenue due to changes in average 
balances and interest rates for the various types of earning assets and interest-bearing liabilities. In addition, see the Annual and 
Quarterly Financial Summary of consolidated daily average balances, yields and rates following the Consolidated Financial 
Statements.

Net interest margin was 2.83% for 2020 and 3.11% for 2019. The tax-equivalent yield on earning assets was 3.24% for 2020 
compared to 4.27% in 2019. In response to the anticipated impact to the economy from the COVID-19 pandemic, the Federal 
Reserve reduced the federal funds rate to near zero in March, 2020. The resulting impact on market interest rates has 
compressed the net interest margin. The company has been proactive in reducing deposit costs and implementing LIBOR floors 
in loan agreements; however, funds received from available for sale securities have been reinvested at lower rates. Loan yields 
decreased 129 basis points to 3.84%. The available for sale securities portfolio yield decreased 37 basis points to 2.21%. The 
yield on trading securities fell 80 basis points to 2.75%. The yield on interest-bearing cash and cash equivalents decreased 183 
basis points to 0.45%.  

Funding costs decreased 108 basis points compared to 2019. The cost of interest-bearing deposits decreased 69 basis points. 
The cost of other short-term borrowings decreased 161 basis points. The benefit to net interest margin from earning assets 
funded by non-interest bearing liabilities was 12 basis points for 2020, down from 45 basis points for 2019.

Average earning assets for 2020 increased $4.3 billion or 12% over 2019, largely due to the expansion of the available for sale 
securities portfolio, loans originated as part of the Small Business Administration's Paycheck Protection Program ("PPP"), and 
an increase in our trading of U.S. government issued mortgage-backed securities. The average balance of available for sale 
securities, which consists largely of residential and commercial mortgage-backed securities guaranteed by U.S. government 
agencies, increased $2.3 billion. We purchase securities to supplement earnings and to manage interest rate risk. We increased 
the size of our bond portfolio during the latter half of 2019 and first quarter 2020 in order to reduce our exposure to falling 
short-term interest rates. Average loans, net of allowance for loan losses, increased $1.1 billion, primarily related to $1.4 billion 
in average PPP loans. Trading securities balances increased $1.3 billion. 

Total average deposits grew by $7.1 billion over the prior year. This increase is largely due to the combination of focused 
deposit gathering initiatives, stimulus-related deposits, and customers retaining elevated balances in the current economic 
environment. Average interest-bearing transaction account balances increased $5.6 billion. Average demand deposit balances 
increased $1.4 billion. Average short-term borrowings decreased $1.7 billion. 

Our overall objective is to manage the Company’s balance sheet to be relatively neutral to changes in interest rates as is further 
described in the Market Risk section of this report. As shown in Table 21, approximately 70% of our commercial and 
commercial real estate loan portfolios are either variable rate loans or fixed rate loans that will re-price within one year. These 
loans are funded primarily by deposit accounts that are either non-interest bearing, or that re-price more slowly than the 
loans. The result is a balance sheet that would be asset sensitive, which means that assets generally re-price more quickly than 
liabilities. Among the strategies that we use to manage toward a relatively rate-neutral position, we purchase fixed rate 
residential mortgage-backed securities issued primarily by U.S. government agencies and fund them with market rate sensitive 
liabilities. The liability-sensitive nature of this strategy provides an offset to the asset-sensitive characteristics of our loan 
portfolio. We also may use derivative instruments to manage our interest rate risk. 

The effectiveness of these strategies is reflected in the overall change in net interest revenue due to changes in interest rates as 
shown in Table 2 and in the interest rate sensitivity projections as shown in the Market Risk section of this report.

Fourth Quarter 2020 Net Interest Revenue

Tax-equivalent net interest revenue totaled $299.6 million for the fourth quarter of 2020, an increase of $26.7 million compared 
to the fourth quarter of 2019. Net interest revenue increased $44.5 million, primarily due to the increase in trading securities, 
available for sale securities and loan balances. This was partially offset by a decrease of $17.8 million primarily due to lower 
market interest rates in 2020. 

Net interest margin was 2.72% for the fourth quarter of 2020 compared to 2.88% for the fourth quarter of 2019. The tax-
equivalent yield on earning assets was 2.92% for the fourth quarter of 2020, a decrease of 101 basis points compared to the 
fourth quarter of 2019, primarily due to the impact on interest rates related to the federal funds rate cuts in 2020. Loan yields 
decreased 107 basis points to 3.68%. Yield on available for sale securities decreased 54 basis points to 1.98%. Yield on trading 
securities decreased 117 basis points to 2.02%. 

Funding costs decreased 112 basis points compared to the fourth quarter of 2019. The cost of other short-term borrowings 
decreased 145 basis points. The cost of interest-bearing deposits decreased 90 basis points. The benefit to net interest margin 
from earning assets funded by non-interest bearing liabilities was 8 basis points in the fourth quarter of 2020, down from 35 
basis points in the fourth quarter of 2019.

Average earning assets for the fourth quarter of 2020 increased $6.3 billion over the fourth quarter of 2019. Trading securities 
balances increased $5.2 billion as we increased our trading of U.S. government issued mortgage-backed securities. Available 
for sale securities increased $1.6 billion as the balance sheet was repositioned for the current rate environment. Average loans, 
net of allowance for loan losses, increased $1.0 billion, largely due to the loans related to the PPP. Fair value option securities 
held as an economic hedge of our mortgage servicing rights decreased $1.4 billion. 

Average deposits increased $8.4 billion over the fourth quarter of 2019, largely due to the combination of government stimulus 
payments and customers choosing to retain elevated balances in the current environment. Average interest-bearing transaction 
accounts increased $6.0 billion and average demand deposit balances increased $2.5 billion. Average short-term borrowings 
decreased $3.0 billion. 

2019 Net Interest Revenue

Tax-equivalent net interest revenue for 2019 was $1.1 billion, up from $993.8 million for 2018. The acquisition of CoBiz in the 
fourth quarter of 2018 added $158.5 million to net interest revenue in 2019 and $43.1 million to net interest revenue in 2018. 
This includes $37.8 million of net purchase discount accretion for 2019 and $6.4 million for 2018. Net interest revenue 
decreased $13.7 million due to rates and increased $144.4 million from growth in earning assets. 

Net interest margin was 3.11% for 2019 compared to 3.20% for 2018. The tax-equivalent yield on average earning assets 
increased 29 basis points over 2018. Short-term rate increases during the first half of 2019 resulting from four 25 basis point 
increases in the federal funds rate by the Federal Reserve during 2018 were partially offset by three 25 basis point decreases in 
the federal funds rate in the second half of 2019. Loan yields increased 33 basis points. The available for sale securities 
portfolio yield increased 23 basis points.The yield on interest-bearing cash and cash equivalents increased 48 basis points. The 
yield on trading securities fell 29 basis points. The cost of interest-bearing liabilities increased 42 basis points. The cost of 
interest-bearing deposits increased 39 basis points and the cost of other short-term borrowings increased 35 basis points. The 
benefit to net interest margin from earning assets funded by non-interest bearing liabilities was 45 basis points for 2019, 
compared to 41 basis points for 2018.

Average earning assets increased $5.4 billion or 18% over 2018, largely due to acquired loans from the CoBiz acquisition 
combined with the expansion of the available for sale securities portfolio. Average loans, net of allowance for loan losses, 
increased $3.4 billion. The average balance of available for sale securities increased $1.8 billion. Total average deposits grew 
by $2.8 billion over 2018, largely related to acquired deposits. Average interest-bearing transaction deposits increased $2.5 
billion. Average short-term borrowings increased $2.9 billion, primarily from increased borrowings from federal funds 
purchased and the Federal Home Loan Banks.

result of the revenue recognition standard implemented January 1, 2018. This measure has no effect on net income or earnings per share. 

Fees and commissions revenue

Diversified sources of fees and commissions revenue are a significant part of our business strategy and represented 42% of total 
revenue for 2020, excluding provision for credit losses and gains and losses on asset sales, securities and derivatives and the 
change in the fair value of mortgage servicing rights. We believe that a variety of fee revenue sources provides an offset to 
changes in interest rates, values in the equity markets, commodity prices and consumer spending, all of which can be 
volatile. As an example of this strength, many of the economic factors such as rising interest rates resulting in growth in net 
interest revenue or fiduciary and asset management revenue may also decrease mortgage banking production volumes and 
related trading. We expect growth in other operating revenue to come through offering new products and services and by 
further development of our presence in other markets. However, current and future economic conditions, including the impact 
of the COVID-19 pandemic, regulatory constraints, increased competition and saturation in our existing markets could affect 
the rate of future increases.

Brokerage and trading revenue, which includes revenues from trading, customer hedging, retail broker and investment banking, 
increased $62.0 million or 39% over the prior year. 

Trading revenue includes net realized and unrealized gains and losses primarily related to sales of residential mortgage-backed 
securities guaranteed by U.S. government agencies and related derivative instruments that enable our mortgage-banking 
customers to manage their production risk. Trading revenue also includes net realized and unrealized gains and losses on 
municipal securities, asset-backed securities and other financial instruments that we sell to institutional customers, along with 
changes in the fair value of financial instruments we hold as economic hedges against market risk of our trading securities. 
Trading revenue was $144.3 million for 2020, an increase of $55.7 million over 2019. Industry-wide mortgage loan production 
increased in 2020 driven by lower interest rates as the Federal Reserve stepped in to provide market stability. We increased our 
bond trading pipeline to provide greater liquidity to the housing market during a time of record loan production volumes.

Customer hedging revenue is based primarily on realized and unrealized changes in the fair value of derivative contracts held 
for customer risk management programs. As more fully discussed under Customer Derivative Programs in Note 3 of the 
Consolidated Financial Statements, we offer commodity, interest rate, foreign exchange and equity derivatives to our 
customers. Derivative contracts executed with customers are offset with contracts between selected counterparties and 
exchanges to minimize market risk from changes in commodity prices, interest rates or foreign exchange rates. Customer 
hedging revenue totaled $22.7 million for 2020, an increase of $3.8 million or 20% compared to 2019. Customer hedging 
revenue on energy derivatives is up $12.2 million as energy customers have increased hedging activity in the volatile 
commodity price environment. This is offset by a $9.6 million decrease on to-be-announced derivatives reflecting a shift in the 
mix of our to-be-announced residential mortgage-backed securities contracts from our customer hedging program to our trading 
program. 

Revenue earned from retail brokerage transactions totaled $15.7 million for 2020, relatively consistent with the prior 
year. Retail brokerage revenue is primarily based on fees and commissions earned on sales of fixed income securities, annuities, 
mutual funds and other financial instruments to retail customers. Revenue is primarily based on the volume of customer 
transactions and applicable commission rate for each type of product. 

Insurance brokerage fees were $12.7 million for 2020, a decrease of $1.2 million compared to the prior year.

Investment banking, which includes fees earned upon completion of underwriting, financial advisory services and loan 
syndication fees, totaled $26.4 million for 2020, an increase of $4.1 million or 18% compared to 2019, related to the timing and 
volume of completed transactions. 

Transaction card revenue depends largely on the volume and amount of transactions processed, the number of TransFund 
automated teller machine (“ATM”) locations and the number of merchants served. Transaction card revenue totaled $90.2 
million for 2020, a $3.0 million or 3% increase over 2019. Revenues from the processing of transactions on behalf of the 
members of our TransFund electronic funds transfer ("EFT") network totaled $78.4 million, up $1.0 million or 1% over 
2019. The number of TransFund ATM locations totaled 2,599 at December 31, 2020 compared to 2,463 at December 31, 2019. 
Merchant services fees paid by customers for account management and electronic processing of card transactions totaled $9.2 
million, relatively consistent with the prior year.

Fiduciary and asset management revenue is earned through managing or holding of assets for customers and executing 
transactions or providing related services. Approximately 90% of fiduciary and asset management revenue is primarily based 
on the fair value of assets. Rates applied to those asset values vary based on the nature of the relationship. Fiduciary and 
managed asset relationships generally have a higher fee rate than non-fiduciary and/or managed relationships.

Fiduciary and asset management revenue decreased $9.6 million or 5% compared to 2019. The low rate environment has put 
pressure on our mutual fund revenue streams, partially offset by increased trust and managed account fees from higher client 
asset balances.We also had approximately $5.6 million in fee waivers during 2020 as a result of the significant decline in 
interest rates. We have voluntarily waived certain administration fees on the Cavanal Hill money market funds in order to 
maintain positive yields on these funds in the current low short-term interest rate environment.

Mortgage banking revenue totaled $182.4 million for 2020, a $74.8 million or 70% increase compared to 2019. Mortgage 
production revenue increased $83.1 million. Production volume is up $1.0 billion as average primary interest rates decreased 84 
basis points compared to 2019. Gain on sale margin also increased 172 basis points to 3.16%. A rapid decrease in interest rates 
has led to increased application demand and industry-wide capacity constraints. Mortgage servicing revenue was $56.5 million, 
an $8.3 million decrease compared to the prior year. The outstanding principal balance of mortgage loans serviced for others 
totaled $16.2 billion at December 31, 2020, a $4.5 billion decrease compared to December 31, 2019, largely due to our strategic 
decision to focus on higher-margin products and distribution channels along with a sale of mortgage servicing rights. During 
the second quarter of 2020, we completed a sale of mortgage servicing rights on $1.6 billion of unpaid principal balance, 
primarily related to loans guaranteed by the Veteran's Administration. Completion of this sale meaningfully reduced the future 
expected credit losses in the servicing portfolio.

Net gains on securities, derivatives and other assets

As discussed in the Market Risk section following, the fair value of our mortgage servicing rights ("MSRs") changes in 
response to changes in primary mortgage loan rates and other assumptions. We attempt to mitigate the earnings volatility 
caused by changes in the fair value of MSRs by designating certain financial instruments as an economic hedge. Changes in the 
fair value of these instruments are generally expected to partially offset changes in the fair value of MSRs. 

The net economic benefit of the changes in fair value of mortgage servicing rights and related economic hedges was $24.9 
million in 2020, including a $95.3 million increase in the fair value of securities and derivative contracts held as an economic 
hedge, offset by a $79.5 million decrease in the fair value of mortgage servicing rights and $9.1 million of related net interest 
revenue. 

The net economic cost of changes in the fair value of mortgage servicing rights and related economic hedges was $17.9 million
in 2019. The fair value of mortgage servicing rights decreased $53.5 million. The fair value of securities and interest rate 
derivative contracts held as an economic hedge increased $30.4 million. Net interest earned on securities held as an economic 
hedge was $5.2 million. 

The significant improvement in results versus 2019 was due to the combination of a more favorable mortgage servicing rights 
risk profile; increased volume and carry on the hedge portfolio; positive hedge strategy performance; and positive economics on 
the sale of GNMA servicing rights.

Fourth Quarter 2020 Other Operating Revenue

Other operating revenue was $196.8 million for the fourth quarter of 2020, an $18.2 million or 10% increase over the fourth 
quarter of 2019. 

Mortgage banking revenue was $39.3 million for the fourth quarter of 2020, an increase of $13.9 million. A decrease in 
mortgage interest rates in 2020 increased mortgage loan production. Mortgage loan production volumes were $819 million for 
the fourth quarter of 2020, compared to $635 million in the fourth quarter of 2019. The fourth quarter of 2020 included a $6.0 
million increase in the fair value of mortgage servicing rights, net of economic hedges, while the fourth quarter of 2019
included a $3.7 million decrease.

Other gains and losses, net, increased $7.0 million largely due to changes in the fair value of assets related to the deferred 
compensation plan and equity securities not held for trading purposes. 

Brokerage and trading revenue was $39.5 million for the fourth quarter of 2020, a decrease of $4.3 million, largely due to the 
shift of brokerage and trading fee revenue to net interest revenue partially offset by increased customer hedging fees and 
investment banking revenue. Fiduciary and asset management revenue decreased $3.2 million while deposit service charges 
decreased $3.0 million.

2019 Other Operating Revenue

Other operating revenue totaled $694.4 million for 2019, an increase of $77.6 million or 13% compared to 2018 driven by 
growth in brokerage and trading revenue and mortgage banking revenue. A $15.4 million fee earned through the sale of client 
assets was recognized as fiduciary and asset management revenue in 2018. This fee is excluded from the fluctuation discussion 
below.

Brokerage and trading revenue for 2019 increased $51.5 million compared to 2018. Lower mortgage interest rates during 2019 
increased customer mortgage-backed trading activities. Trading revenue increased $60.5 million in 2019. Customer hedging 
revenue decreased $19.9 million compared to 2018. This is reflective of a shift in the mix of our to-be-announced residential 
mortgage-backed securities contracts from our customer hedging program to our trading program. Insurance brokerage fees 
increased $9.7 million compared to 2018 due to a full of year of operations with the addition of CoBiz in October, 2018.

Transaction card revenue grew by $3.2 million over 2018, primarily due to growth in transaction volumes. Fiduciary and asset 
management revenue grew $7.7 million over 2018, primarily due to growth in managed fiduciary assets.

Mortgage banking revenue increased by $9.8 million over 2018. Lower mortgage interest rates led to an increase in the supply 
of mortgage applications.

Other Operating Expense

Other operating expense for 2020 totaled $1.2 billion, a $33.6 million or 3% increase over the prior year. CoBiz added $17.2 
million in integration costs during 2019. Excluding those costs, operating expense increased $50.8 million, largely related to 
incentive compensation. The fluctuation discussion below excludes the impact of closing and integration costs.

Personnel expense

Personnel expense increased $30.8 million in 2020. Incentive compensation increased $41.8 million or 25% over 2019. Cash-
based incentive compensation plans, which are either intended to provide current rewards to employees who generate long-term 
business opportunities for the Company based on growth in loans, deposits, customer relationships and other measurable 
metrics or intended to compensate employees with commissions on completed transactions, grew $41.6 million or 29% over 
2019, largely related to the growth in mortgage-backed securities trading activities. This increase was partially offset by lower 
employee benefits costs of $7.2 million or 8%, largely related to decreased employee healthcare costs.

Non-personnel expense

Non-personnel expense increased $20.0 million or 4% over the prior year. 

Data processing and communications expense increased $12.5 million or 10% primarily due to technology project costs. 
Occupancy and equipment expense increased $6.4 million or 6%, largely due to increased cleaning costs during the pandemic 
as well as increased depreciation costs. Mortgage banking expense increased $6.0 million or 12%, primarily due to an increase 
in prepayments and accruals related to default servicing and loss mitigation costs on loans serviced for others. Charitable 
contributions to the BOKF Foundation increased $6.0 million as we focus on the communities we serve and the extreme needs 
created by the pandemic. Professional fees increased $5.0 million or 10%. Net losses and operating expenses of repossessed 
assets increased $4.0 million or 60% over the prior year mainly due to write-downs on a set of oil and gas properties and a retail 
commercial real estate property during the year. 

Business promotion costs, consisting largely of travel and entertainment and advertising costs, were down $19.5 million or 
57%, primarily due to the effects of the current pandemic.  

Fourth Quarter 2020 Operating Expenses

Other operating expense for the fourth quarter of 2020 totaled $300.7 million, an increase of $11.9 million over the fourth 
quarter of 2019. 

Personnel expense increased $7.8 million over the fourth quarter of 2019 An increase in incentive compensation costs of $12.2 
million was partially offset by a decrease of $3.4 million in regular compensation. Cash-based incentive compensation 
increased $11.4 million due to increased activity, particularly in the mortgage banking and trading areas. Deferred 
compensation expense increased $3.1 million, which is largely offset by changes in the fair value of assets held in rabbi trusts 
for the benefit of participants. Share-based compensation expense, which represents expense for equity awards based on the 
grant date fair value, decreased $2.3 million due to changes in vesting assumptions related to performance-based share awards.

Non-personnel expense increased $4.1 million compared to the fourth quarter of 2019. Data processing and communications 
costs increased $3.2 million related to technology projects. Charitable contributions to the BOKF Foundation increased $4.0 
million. These increases were partially offset by a decrease in business promotion expense of $5.1 million, largely related to 
lower travel and entertainment costs during the pandemic.

2019 Operating Expenses

Other operating expense totaled $1.1 billion for 2019, a $104.2 million or 10% increase over 2018. CoBiz added $17.2 million 
in closing and integration costs in 2019 and $16.6 million in 2018. The fluctuation discussion below excludes these costs.

Personnel expense increased $80.3 million in 2019. Regular compensation expense increased $36.0 million, largely related to 
the addition of CoBiz employees. Incentive compensation grew $37.6 million, primarily related to increased sales activities and 
the addition of CoBiz employees. Cash based incentive compensation grew $16.5 million over 2018. Share-based incentive 
compensation increased $11.3 million due to an increase in the vesting probability of certain performance-based share awards. 
Deferred compensation expense increased $9.8 million. This expense is largely offset by changes in the fair value of assets held 
in rabbi trusts for the benefit of participants, which is included in other gains (losses). 

Non-personnel expense increased $23.3 million or 5% over 2018. Intangible asset amortization increased $11.0 million due to 
the addition of CoBiz. Occupancy and equipment expense increased $8.4 million, primarily related to the addition of CoBiz 
operations. Data processing and communications expense increased $8.5 million due to technology project costs. Mortgage 
banking costs increased $4.4 million, largely due to an increase in prepayments.

Net losses and operating expenses of repossessed assets decreased $10.3 million compared to 2018 mainly due to write-downs 
on a set of oil and gas properties and a healthcare property in 2018. Insurance expense decreased $2.6 million, largely due to the 
elimination of a large bank deposit insurance surcharge assessed by the FDIC in the fourth quarter of 2018.

Income Taxes

Income tax expense was $128.8 million or 22.8% of net income before taxes for 2020, $130.2 million or 20.6% of net income 
before taxes for 2019 and $119.1 million or 21.1% of net income before taxes for 2018.

Net deferred tax liabilities totaled $9.5 million at December 31, 2020 compared to net deferred tax liabilities of $26 million at 
December 31, 2019. We have evaluated the recoverability of our deferred tax assets based on the generation of future taxable 
income during the periods in which those temporary differences become deductible and determined that no valuation allowance 
was required in 2020 and 2019.

Income tax expense was $45.1 million or 22.6% of net income before taxes for the fourth quarter of 2020 compared to $30.3 
million or 21.5% of net income before taxes for the fourth quarter of 2019.

Lines of Business

We operate three principal lines of business: Commercial Banking, Consumer Banking and Wealth Management. Commercial 
Banking includes lending, treasury and cash management services and customer risk management products for small 
businesses, middle market and larger commercial customers. Commercial Banking also includes the TransFund EFT 
network. Consumer Banking includes retail lending and deposit services, lending and deposit services to small business 
customers served through our consumer branch network and all mortgage loan origination and servicing activities. Wealth 
Management provides fiduciary services, private bank services, insurance and investment advisory services in all 
markets. Wealth Management also underwrites state and municipal securities and engages in brokerage and trading activities.

In addition to our lines of business, we have a Funds Management unit. The primary purpose of this unit is to manage our 
overall liquidity needs and interest rate risk. Each line of business borrows funds from and provides funds to the Funds 
Management unit as needed to support their operations. Operating results for Funds Management and other include the effect of 
interest rate risk positions and risk management activities, securities gains and losses including impairment charges, the 
provision for credit losses in excess of net loans charged off, tax planning strategies and certain executive compensation costs 
that are not attributed to the lines of business. The Funds Management unit also initially recognizes accruals for loss 
contingencies when losses become probable. Actual losses are recognized by the lines of business if the accruals are settled. 

We allocate resources and evaluate the performance of our lines of business using the net direct contribution, which includes 
the allocation of funds, actual net credit losses and capital costs. In addition, we measure the performance of our business lines 
after allocations of certain indirect expenses and taxes based on statutory rates. 

The cost of funds borrowed from the Funds Management unit by the operating lines of business is transfer priced at rates that 
approximate market rates for funds with similar repricing and cash flow characteristics. Market rates are generally based on the 
applicable LIBOR or interest rate swap rates, adjusted for prepayment risk and liquidity risk. This method of transfer-pricing 
funds that support assets of the operating lines of business tends to insulate them from interest rate risk. 

The value of funds provided by the operating lines of business to the Funds Management unit is also based on rates that 
approximate wholesale market rates for funds with similar repricing and cash flow characteristics. Market rates are generally 
based on LIBOR or interest rate swap rates. The funds credit formula applied to deposit products with indeterminate maturities 
is established based on their repricing characteristics reflected in a combination of the short-term LIBOR rate and a moving 
average of an intermediate term swap rate, with an appropriate spread applied to both. Shorter duration products are weighted 
towards the short term LIBOR rate and longer duration products are weighted towards the intermediate swap rates. The 
expected duration ranges from 30 days for certain rate-sensitive deposits to five years. During 2018, the funds transfer pricing 
rates for non-maturity deposits became inverted due to the flattening of the yield curve. Short term rates continued to increase 
while long term rates remained relatively flat. In order to appropriately reflect the organizational value of these deposits to the 
lines of business, we increased the funding credit to reflect the upward rate moves. Those adjustments are set annually each 
January. During 2019, short-term rates moved down materially, which was reflected in the funding credit to the business lines 
beginning in January, 2020.

Economic capital is assigned to the business units by a capital allocation model that reflects management’s assessment of 
risk. This model assigns capital based upon credit, operating, interest rate and other market risk inherent in our business lines 
and recognizes the diversification benefits among the units. The level of assigned economic capital is a combination of the risk 
taken by each business line, based on its actual exposures and calibrated to its own loss history where possible. Average 
invested capital includes economic capital and amounts we have invested in the lines of business.

As shown in Table 10 following, net income attributable to our lines of business decreased $9.8 million or 2% compared to the 
prior year. Net interest revenue decreased by $119.0 million compared to the prior year, primarily due to decreases in the short-
term interest rate related to a 225 basis point reduction in the federal funds rate by the Federal Reserve since the middle of 
2019. Net charge-offs were up $27.1 million over the prior year. Other operating revenue increased $130.6 million led by our 
brokerage and trading and mortgage banking businesses. Other operating expense increased $57.3 million compared to prior 
year, largely due to increased incentive compensation related to trading activities. The increase in net loss attributed to Funds 
Management and other is largely due to the excess provision for expected credit losses over net charge-offs.

Net interest revenue decreased $87.8 million or 13% compared to the prior year. Yields on deposits sold to the Funds 
Management unit decreased as the value of deposits was impacted by falling interest rates. Net loans charged-off increased 
$30.5 million. 

Fees and commissions revenue increased $18.5 million or 11% due to growth in customer energy hedging revenue and an 
increase in revenues from the processing of transactions on behalf of the members of our TransFund EFT network. 

Operating expense increased $6.4 million or 3% over 2019. Non-personnel expense increased $10.4 million or 12%. Increases 
in data processing and communications expense, occupancy and equipment expense, intangible amortization and deposit 
insurance costs were partially offset by a decrease in business promotion expense. Personnel expense decreased $3.9 million or 
2%. An decrease in incentive compensation costs was partially offset by an increase in regular compensation. Corporate 
expense allocations decreased $18.2 million or 42% compared to the prior year.

The average outstanding balance of loans attributed to Commercial Banking was up $621 million or 3% over 2019 to $18.7 
billion, primarily due to the full year benefit of acquired loans from CoBiz. Prior to April 1, 2019, CoBiz loans were attributed 
to Funds Management and other. See the Loans section of Management's Discussion and Analysis of Financial condition 
following for additional discussion of changes in commercial and commercial real estate loans, which are primarily attributed to 
the Commercial Banking segment.  

Average deposits attributed to Commercial Banking were $14.3 billion for 2020, a 39% increase over the prior year. See 
Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital for further 
discussion of change.  

Consumer Banking

Consumer Banking services are provided through four primary distribution channels: traditional branches, the 24-hour 
ExpressBank call center, Internet banking and mobile banking. Consumer Banking also conducts mortgage banking activities 
through offices located outside of our Consumer Banking markets. In the first quarter of 2019, the strategic decision was made 
to exit our online lead buying business, HomeDirect, to focus more on our core competency of developing complete, long-term 
relationships with our clients through our traditional mortgage origination channel. 

Net income attributed to Consumer Banking totaled $95.4 million for 2020, compared to $56.6 million in the prior 
year. Improved performance by Consumer Banking was largely due to the effect of lower mortgage interest rates, which has 
increased mortgage banking activity and related revenue.

Net interest revenue from Consumer Banking activities decreased by $48.5 million or 25% compared to 2019, primarily due to 
a decrease in the yield on deposits sold to our Funds Management unit. Average consumer deposits grew $723 million with 
demand deposit balances up by $470 million or 22%. 

Fees and commissions revenue increased $57.6 million or 31% over the prior year. Lower mortgage interest rates increased 
mortgage loan origination volumes. Mortgage production volume increased $1.0 billion or 34% and gain on sale margin 
increased 172 basis points due to industry-wide capacity constraints. Deposit service charges decreased $15.4 million. During 
these uncertain times, we proactively waived certain fees. In addition, the pandemic has resulted in customers retaining cash 
and not maintaining the usual level of spending, which has decreased overdraft fees compared to the prior year. Operating 
expense increased $2.5 million or 1% over 2019. An increase in mortgage banking costs was largely offset by lower business 
promotion expenses. Corporate expense allocations were $4.5 million or 10% lower than the prior year.

Changes in the fair value of our mortgage servicing rights, net of economic hedges, as more fully presented in Table 7, resulted 
in a $15.8 million increase to pre-tax net income for 2020 compared to a $23.1 million decrease to pre-tax net income in 2019.

Wealth Management

Wealth Management contributed $115.6 million to consolidated net income in 2020, up $20.3 million or 21% over the prior 
year. Increased fees and commissions revenue, primarily from U.S. agency residential mortgage-backed securities and related 
derivatives trading, was partially offset by related incentive compensation costs.

Revenue attributed to the Wealth Management segment totaled $516.1 million for 2020, a $74.6 million or 17% increase over 
the previous year. Net interest revenue increased $17.2 million and fees and commissions revenue increased $57.9 million. 

Demand for mortgage loans and related derivative contracts increased significantly due to a decrease in mortgage interest rates 
that began in early 2020 and continued throughout the year. We expanded trading activities that provide liquidity to our 
mortgage banking customers and enable them to manage their market risk. Our expanded trading activities are subject to limits 
established by the Board of Directors as discussed in the Market Risk section following. Growth in transaction volumes resulted 
in an $89.7 million increase in combined net interest revenue and trading revenue. Our level of trading volume is largely 
dependent on industry-wide mortgage loan production.

Growth in total revenue from expanded trading activities was partially offset by decreased net interest revenue generated by 
deposits sold to our Funds Management unit and loans attributed to the Wealth Management segment, and fiduciary and asset 
management fees. Both were negatively affected by the current low short-term interest rate environment.

Operating expense increased $48.3 million or 17% over the prior year. Personnel expense increased $42.1 million or 21% 
primarily related to incentive compensation as a result of higher trading activity. Non-personnel expense increased $6.2 million 
or 8% over 2019. Corporate expense allocations were relatively consistent compared to the prior year.

We maintain an inventory of trading securities in support of sales to a variety of customers, including banks, corporations, 
insurance companies, money managers and others. As discussed in the Market Risk section of this report, trading activities 
involve risk of loss from adverse price movement. We mitigate this risk within board-approved limits through the use of 
derivative contracts, short-sales and other techniques. These limits remain unchanged from levels set before our expanded 
trading activities. For further discussion of growth in trading securities, see "Lines of Business" section of Management's 
Discussion and Analysis.

Investment securities consist primarily of intermediate and long-term, fixed rate Oklahoma and Texas municipal bonds and 
taxable Texas school construction bonds. The investment security portfolio is diversified among issuers.

Available for sale securities, which may be sold prior to maturity, are carried at fair value. Unrealized gains or losses, net of 
deferred taxes, are recorded as accumulated other comprehensive income in shareholders’ equity. The amortized cost of 
available for sale securities totaled $12.6 billion at December 31, 2020, an increase of $1.5 billion compared to December 31, 
2019. Available for sale securities consist primarily of U.S. government agency residential mortgage-backed securities and U.S. 
government agency commercial mortgage-backed securities. Both residential and commercial mortgage-backed securities have 
credit risk from delinquency or default of the underlying loans. We mitigate this risk by primarily investing in securities issued 
by U.S. government agencies. Principal and interest payments on the underlying loans are fully guaranteed. Commercial 
mortgage-backed securities have prepayment penalties similar to commercial loans. At December 31, 2020, residential 
mortgage-backed securities represented 72% of total available for sale securities. 

A primary risk of holding residential mortgage-backed securities comes from extension during periods of rising interest rates or 
prepayment during periods of falling interest rates. We evaluate this risk through extensive modeling of risk both before making 
an investment and throughout the life of the security. Our best estimate of the effective duration of the combined residential 
mortgage-backed securities portfolio held in investment and available for sale securities portfolios at December 31, 2020 is 2.3 
years. Management estimates the combined portfolios' duration extends to 4.0 years assuming an immediate 200 basis point 
upward shock. The estimated duration contracts to 1.9 years assuming a 100 basis point decline in the current low rate 
environment. 

The aggregate gross amount of unrealized losses on available for sale securities totaled $8.8 million at December 31, 2020, an 
$11.4 million decrease compared to December 31, 2019. On a quarterly basis, we perform an evaluation on debt securities to 
determine if the unrealized losses are temporary as more fully described in Note 2 of the Consolidated Financial Statements. No 
other-than-temporary impairment charges were recognized in earnings in 2020.

Certain residential mortgage-backed securities issued by U.S. government agencies and included in Fair value option securities 
on the Consolidated Balance Sheets have been segregated and designated as economic hedges of changes in the fair value of 
our mortgage servicing rights. We have elected to carry these securities at fair value with changes in fair value recognized in 
current period income. These securities are held with the intent that gains or losses will offset changes in the fair value of 
mortgage servicing rights and related derivative contracts. Fair value option securities totaled $115 million, a decrease of $984 
million. See Market Risk section for further details.

Bank-Owned Life Insurance

We have approximately $399 million of bank-owned life insurance at December 31, 2020. This investment is expected to 
provide a long-term source of earnings to support existing employee benefit programs. Approximately $308 million is held in 
separate accounts. Our separate account holdings are invested in diversified portfolios of investment-grade fixed income 
securities and cash equivalents, including U.S. Treasury and Agency securities, residential mortgage-backed securities, 
corporate debt, asset-backed and commercial mortgage-backed securities. The portfolios are managed by unaffiliated 
professional managers within parameters established in the portfolio’s investment guidelines. The cash surrender value of 
certain life insurance policies is further supported by a stable value wrap, which protects against changes in the fair value of the 
investments. As of December 31, 2020, the fair value of investments held in separate accounts was approximately $331 
million. As the underlying fair value of the investments held in a separate account at December 31, 2020 exceeded the net book 
value of the investments, no cash surrender value was supported by the stable value wrap. The stable value wrap is provided by 
a domestic financial institution. The remaining cash surrender value of $91 million primarily represents the cash surrender 
value of policies held in general accounts and other amounts due from various insurance companies.

Loans

The aggregate loan portfolio before allowance for loan losses totaled $23.0 billion at December 31, 2020, an increase of $1.3 
billion over December 31, 2019, primarily due to PPP loans, partially offset by commercial loan paydowns.

Commercial loans represent loans for working capital, facilities acquisition or expansion, purchases of equipment and other 
needs of commercial customers primarily located within our geographical footprint. Commercial loans are underwritten 
individually and represent ongoing relationships based on a thorough knowledge of the customer, the customer’s industry and 
market. While commercial loans are generally secured by the customer’s assets including real property, inventory, accounts 
receivable, operating equipment, interests in mineral rights and other property and may also include personal guarantees of the 
owners and related parties, the primary source of repayment of the loans is the on-going cash flow from operations of the 
customer’s business. Inherent lending risks are centrally monitored on a continuous basis from underwriting throughout the life 
of the loan for compliance with commercial lending policies.

Commercial loans totaled $13.1 billion or 57% of the loan portfolio at December 31, 2020, decreasing $954 million or 7%
compared to December 31, 2019. Borrowers continue to reduce leverage during this time of economic uncertainty.

Approximately 78% of loans in this segment are located within our geographic footprint, based on collateral location. Loans for 
which the collateral location is less relevant, such as unsecured loans and reserve-based energy loans are categorized by the 
borrower's primary operating location. The largest concentration of loans in this segment outside of our footprint is California, 
totaling 5% of the segment.

Supporting the energy industry with loans to producers and other energy-related entities has been a hallmark of the Company 
since its founding and represents a large portion of our commercial loan portfolio. In addition, energy production and related 
industries have a significant impact on the economy in our primary markets. Loans collateralized by oil and gas properties are 
subject to a semi-annual engineering review by our internal staff of petroleum engineers. This review is used as the basis for 
developing the expected cash flows supporting the loan amount. The projected cash flows are discounted according to risk 
characteristics of the underlying oil and gas properties. Loans are evaluated to demonstrate with reasonable certainty that crude 
oil, natural gas and natural gas liquids can be recovered from known oil and gas reservoirs under existing economic and 
operating conditions at current pricing levels and with existing conventional equipment and operating methods and costs. As 
part of our evaluation of credit quality, we analyze rigorous stress tests over a range of commodity prices and take proactive 
steps to mitigate risk when appropriate.

Outstanding energy loans totaled $3.5 billion or 15% of total loans at December 31, 2020. Approximately $2.6 billion or 76% 
of energy loans were to oil and gas producers, a $497 million decrease compared to December 31, 2019. The majority of this 
portfolio is first lien, senior secured, reserve-based lending, which we believe is the lowest risk form of energy lending. 
Approximately 67% of the committed production loans are secured by properties primarily producing oil and 33% of the 
committed production loans are secured by properties primarily producing natural gas. 

Loans to midstream oil and gas companies totaled $700 million or 20% of energy loans, an increase of $91 million over the 
prior year. Loans to borrowers that provide services to the energy industry totaled $110 million or 3% of energy loans, a 
decrease of $68 million during 2020. Loans to other energy borrowers, including those engaged in wholesale or retail energy 
sales totaled $36 million or 1% of energy loans, a decrease of $31 million compared to the prior year.

Unfunded energy loan commitments were $2.4 billion at December 31, 2020, down $524 million compared to December 31, 
2019 as a result of the semi-annual borrowing base redetermination process in the second and fourth quarters of 2020.

The healthcare sector of the loan portfolio totaled $3.3 billion or 14% of total loans. Healthcare loans increased $272 million 
over December 31, 2019, primarily due to growth in loans to senior housing and care facilities. Healthcare sector loans consist 
primarily of loans for the development and operation of senior housing and care facilities, including independent living, assisted 
living and skilled nursing. Generally we loan to borrowers with a portfolio of multiple facilities that serves to help diversify 
risks specific to a single facility. Healthcare also includes loans to hospitals and other medical service providers impacted by a 
deferral of elective procedures. The CARES Act includes multiple revenue enhancement measures for both hospitals and skilled 
nursing facilities as they manage through the risks of the virus.

The services sector of the loan portfolio decreased $323 million to $3.5 billion or 15% of total loans. Service sector loans 
consist of a large number of loans to a variety of businesses, including Native American tribal and state and local governments, 
Native American tribal casino operations, educational services, foundations and not-for-profit organizations and specialty trade 
contractors. Approximately $1.9 billion of the services category is made up of loans with individual balances of less than $10 
million. Service sector loans are generally secured by the assets of the borrower with repayment coming from the cash flows of 
ongoing operations of the customer’s business. 

General business loans decreased $399 million to $2.8 billion or 12% of total loans. General business loans primarily consist of 
$1.6 billion of wholesale/retail loans and $701 million of loans from other commercial industries. 

Our services and general business loans include areas we consider to be more exposed to the economic slowdown as a result of 
the social distancing measures in place to combat the COVID-19 pandemic such as entertainment and recreation, retail, hotels, 
churches, airline travel, and higher education that are dependent on large social gatherings to remain profitable. This represents 
less than 7 percent of our total portfolio. Some of these borrowers have participated in the PPP, which has provided some 
measure of relief. We will continue to monitor these areas closely in the coming months.

We participate in shared national credits when appropriate to obtain or maintain business relationships with local customers. 
Shared national credits are defined by banking regulators as credits of more than $100 million and with three or more non-
affiliated banks as participants. At December 31, 2020, the outstanding principal balance of these loans totaled $4.1 billion, 
including $1.8 billion in the energy sector. Approximately 85% of shared national credits are to borrowers with local market 
relationships. We serve as the agent lender in approximately 21% of our shared national credits, based on dollars committed. 

51

We hold shared national credits to the same standard of analysis and perform the same level of review as internally originated 
credits. Our lending policies generally avoid loans in which we do not have the opportunity to maintain or achieve other 
business relationships with the customer. In addition to management’s quarterly assessment of credit risk, banking regulators 
annually review a sample of shared national credits for proper risk grading.

Commercial Real Estate

Commercial real estate represents loans for the construction of buildings or other improvements to real estate and property held 
by borrowers for investment purposes generally within our geographical footprint. We require collateral values in excess of the 
loan amounts, demonstrated cash flows in excess of expected debt service requirements, equity investment in the project and a 
portion of the project already sold, leased or permanent financing already secured. The expected cash flows from all significant 
new or renewed income producing property commitments are stress tested to reflect the risks in varying interest rates, vacancy 
rates and rental rates. As with commercial loans, inherent lending risks are centrally monitored on a continuous basis from 
underwriting throughout the life of the loan for compliance with applicable lending policies.

The commercial real estate loan balance as a percentage of our total loan portfolio has ranged from 20% to 22% over the past 
five years. The outstanding balance of commercial real estate loans increased $265 million over 2019. Continued friction in the 
permanent financing market continued to constrain paydown activity. Loans secured by office buildings increased $157 million 
or 17%. Other real estate loans increased $102 million or 22%. Loans secured by multifamily real estate increased $62 million 
or 5%. These increases were partially offset by a decrease of $46 million or 5% in loans secured by industrial facilities and a 
decrease of $31 million or 21% in construction and land development loans.

Approximately 67% of loans in this segment are in our geographic footprint based on collateral location. The largest 
concentration of loans in this segment outside our footprint is Utah, totaling 8% of the segment, followed by California at 7%. 
All other states represent less than 5% individually.

Loans secured by retail facilities and office buildings may be adversely impacted by measures being taken to hinder the spread 
of the virus as well as changes in consumer behavior.

Paycheck Protection Program

We are actively participating in programs initiated by the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"), 
including the Small Business Administration's ("SBA") Paycheck Protection Program ("PPP") that began on April 3, 2020. PPP 
provided fully forgivable loans when utilized for qualified expenditures, including to help small business maintain payrolls 
during the COVID-19 pandemic. These loans generally have a contractual term of two years, though most are expected to be 
forgiven prior to maturity after completion of a compliance period. Loans are guaranteed and amounts forgiven will be 
reimbursed to the Company by the SBA. The loans carry a rate of 1 percent. Interest plus loan fees, which vary depending on 
loan size, are accrued over the contractual life of the loan. Any unaccreted origination fees will be recognized when the loan is 
paid. Unaccreted origination fees totaled $24 million at December 31, 2020.

PPP loan balances decreased $415 million to $1.7 billion or 7% of total loans. The complexity of the forgiveness process and 
borrowers' reluctance to apply for forgiveness in hopes of further legislative action that would relax the requirements has made 
the forgiveness process slower than initially anticipated. The recent Economic Aid Act will provide substantial forgiveness 
process relief, particularly for those clients with existing loans of less than $150 thousand, which represents more the 70% of 
our total PPP loan volume. The Company expects to participate in the newest round of PPP, with largely the same strategy of 
focusing on our existing client base in order to timely meet our existing clients' needs.

Loans to Individuals

Loans to individuals include residential mortgage and personal loans. Residential mortgage loans provide funds for our 
customers to purchase or refinance their primary residence or to borrow against the equity in their home. These loans are 
secured by a first or second mortgage on the customer's primary residence. These loans are made in accordance with 
underwriting policies we believe to be conservative and are fully documented. Loans may be individually underwritten or credit 
scored based on size and other criteria. Credit scoring is assessed based on significant credit characteristics including credit 
history, residential and employment stability. 

52

In general, we sell the majority of our conforming fixed rate loan originations in the secondary market and retain the majority of 
our non-conforming and adjustable-rate mortgage loans. Our mortgage loan portfolio does not include payment option 
adjustable rate mortgage loans or adjustable rate mortgage loans with initial rates that are below market. Home equity loans are 
primarily first-lien and fully amortizing. 

Residential mortgage, which includes home equity loans, and personal loans are made in accordance with underwriting policies 
we believe to be conservative and are fully documented. Loans may be individually underwritten or credit scored based on size 
and other criteria. Credit scoring is assessed based on significant credit characteristics including credit history, residential and 
employment stability. 

Personal loans consist primarily of loans to Wealth Management clients secured by the cash surrender value of insurance 
policies and marketable securities. It also includes direct loans secured by and for the purchase of automobiles, recreational and 
marine equipment as well as unsecured loans.

Approximately 91% of the loans in this segment are secured by collateral located within our geographical footprint. Loans for 
which the collateral location is less relevant, such as unsecured loans are categorized by the borrower’s primary operating 
location. 

Residential mortgage loans guaranteed by U.S. government agencies have limited credit exposure because of the agency 
guarantee. This amount includes residential mortgage loans previously sold into GNMA mortgage pools that the Company may 
repurchase when certain defined delinquency criteria are met. Because of this repurchase right, the Company is deemed to have 
regained effective control over these loans and must include them on the Consolidated Balance Sheet. Residential mortgage 
loans guaranteed by U.S. government agencies increased $211 million compared to December 31, 2019, primarily due to 
increased delinquencies and CARES Act forbearance. The balances of residential mortgage loans guaranteed by U.S. 
government agencies are expected to decline during the next few quarters as new forbearance plan requests have remained 
muted, which will reduce the Company's repurchase activity relative to 2020. Loans that have exited forbearance and have met 
GNMA requirements will be re-pooled into GNMA mortgage pools.

The Company secondarily evaluates loan portfolio performance based on the primary geographical market managing the loan. 
Loans attributed to a geographical market may not represent the location of the borrower or the collateral. All permanent 
mortgage loans serviced by our mortgage banking unit and held for investment by the Company are centrally managed by the 
Oklahoma market.

We enter into certain off-balance sheet arrangements in the normal course of business as shown in Table 22. Loan commitments 
may be unconditional obligations to provide financing or conditional obligations that depend on the borrower’s financial 
condition, collateral value or other factors. Standby letters of credit are unconditional commitments to guarantee the 
performance of our customer to a third party. Since some of these commitments are expected to expire before being drawn 
upon, the total commitment amounts do not necessarily represent future cash requirements.

We have off-balance sheet commitments related to certain residential mortgage loans sold into mortgage-backed securities as 
part of our mortgage banking activities. We retain off-balance sheet credit risk related to losses in excess of amounts guaranteed 
by the U.S. Department of Veteran's Affairs ("VA"). During the second quarter of 2020, we sold mortgage servicing rights 
related to residential mortgage loans primarily guaranteed by the VA with an unpaid principal balance of $1.6 billion.

We also have off-balance sheet credit risk related to certain residential mortgage loans primarily originated under community 
development loan programs that were sold to a U.S. government agency with full recourse prior to 2007. We are obligated to 
repurchase these loans for the life of these loans in the event of foreclosure for the unpaid principal and interest at the time of 
foreclosure. The majority of our conforming fixed rate loan originations are sold in the secondary market and we only retain 
repurchase obligations under standard underwriting representations and warranties.

The CARES Act provided protections for borrowers with agency-backed residential mortgages that are serviced by the 
Company. Forbearance must be granted upon receiving a request from a borrower and the borrower's attestation to a financial 
hardship associated with the COVID-19 emergency. The Bank is required to offer up to a 6 month forbearance, with the 
possibility of an additional 6 month extension. This program was available to all current and delinquent borrowers, including 
those in bankruptcy and/or foreclosure. As of December 31, 2020, agency-serviced loans in forbearance included 3,258 
borrowers with an unpaid principal balance of $511 million. For certain contracts, we must advance principal and interest 
payments during the forbearance period. Advances as of December 31, 2020 totaled $5.4 million. Advances are generally 
reimbursed to us by the appropriate agencies. Loans in forbearance are considered delinquent when payments are not made for 
purposes of valuing mortgage servicing rights and for purposes of determining GNMA loans that are eligible to be repurchased. 
As of December 31, 2020, 23% of borrowers in forbearance remained current.

Customer Derivative Programs

We offer programs that permit our customers to hedge various risks, including fluctuations in energy, cattle and other 
agricultural product prices, interest rates and foreign exchange rates. Each of these programs work essentially the same 
way. Derivative contracts are executed between the customers and the Company. Offsetting contracts are executed between the 
Company and selected counterparties or exchanges to minimize market risk to us from changes in commodity prices, interest 
rates or foreign exchange rates. The counterparty contracts are identical to the customer contracts, except for a fixed pricing 
spread or a fee paid to us as compensation for administrative costs, credit risk and profit.

The customer derivative programs create credit risk for potential amounts due to the Company from our customers and from the 
counterparties. Customer credit risk is monitored through existing credit policies and procedures. The effects of changes in 
commodity prices, interest rates or foreign exchange rates are evaluated across a range of possible options to determine the 
maximum exposure we are willing to have individually to any customer. Customers may also be required to provide cash 
margin or other collateral in conjunction with our credit agreements to further limit our credit risk.

Counterparty credit risk is evaluated through existing policies and procedures. This evaluation considers the total relationship 
between BOK Financial and each of the counterparties. Individual limits are established by management, approved by Credit 
Administration and reviewed by the Asset/Liability Committee. Margin collateral is required if the exposure between the 
Company and any counterparty exceeds established limits. Based on declines in the counterparties’ credit ratings, these limits 
may be reduced and additional margin collateral may be required.

A deterioration of the credit standing of one or more of the customers or counterparties to these contracts may result in BOK 
Financial recognizing a loss as the fair value of the affected contracts may no longer move in tandem with the offsetting 
contracts. This occurs if the credit standing of the customer or counterparty deteriorated such that either the fair value of 
underlying collateral no longer supports the contract or the customer or counterparty’s ability to provide margin collateral was 
impaired. Credit losses on customer derivatives reduce brokerage and trading revenue in the Consolidated Statements of 
Earnings.

Derivative contracts are carried at fair value. At December 31, 2020, the net fair values of derivative contracts, before 
consideration of cash margin, reported as assets under these programs totaled $625 million compared to $302 million at 
December 31, 2019. Derivative contracts carried as assets include foreign exchange contracts with fair values of $332 million, 
energy contracts with fair values of $175 million and interest rate swaps primarily sold to loan customers with fair values of 
$113 million. Before consideration of cash margin paid to counterparties, the aggregate net fair values of derivative contracts 
held under these programs reported as liabilities totaled $600 million.

At December 31, 2020, total derivative assets were reduced by $705 thousand of cash collateral received from counterparties 
and total derivative liabilities were reduced by $223 million of cash collateral paid to counterparties related to instruments 
executed with the same counterparty under a master netting agreement.

A table showing the notional and fair value of derivative assets and liabilities on both a gross and net basis is presented in Note 
3 to the Consolidated Financial Statements.

The fair value of derivative contracts reported as assets under these programs, net of cash margin held by the Company, by 
category of debtor at December 31, 2020 follows in Table 23.

The largest exposure to a single counterparty was to a customer for an energy swap which totaled $28 million at December 31, 
2020. 

Our customer derivative program also introduces liquidity and capital risk. We are required to provide cash margin to certain 
counterparties when the net negative fair value of the contracts exceeds established limits. Also, changes in commodity prices 
affect the amount of regulatory capital we are required to hold as support for the fair value of our derivative assets. These risks 
are modeled as part of the management of these programs. Based on current prices, a decrease in market prices equal to the 
equivalent of $35.09 per barrel of oil would decrease the fair value of derivative assets by $85 million, with dealer 
counterparties comprising the bulk of the assets. An increase in prices equal to the equivalent of $61.71 per barrel of oil would 
increase the fair value of derivative assets by $506 million. Liquidity requirements of this program are also affected by our 
credit rating. A decrease in credit rating to below investment grade would increase our obligation to post cash margin on 
existing contracts by approximately $10 million. The fair value of our to-be-announced residential mortgage-backed securities 
and interest rate swap derivative contracts is affected by changes in interest rates. Based on our assessment as of December 31, 
2020, changes in interest rates would not materially impact regulatory capital or liquidity needed to support this portion of our 
customer derivative program.

Allowance for Loan Losses and Accrual for Off-Balance Sheet Credit Risk from Unfunded Loan Commitments

The Company adopted FASB Accounting Standard Update No. 2016-13, Financial Instruments – Credit Losses (Topic 326): 
Assets Measured at Amortized Cost ("CECL") on January 1, 2020 through a pre-tax cumulative-effect adjustment to equity of 
$61.4 million. CECL requires recognition of expected credit losses on assets carried at amortized cost over their expected lives. 
The previous incurred loss model incorporated only known information as of the balance sheet date. Prior years reported under 
the incurred loss model have not been restated. CECL uses models to measure the probability of default and loss given default 
over a 12-month reasonable and supportable forecast period. Models incorporate base case, downside, and upside 
macroeconomic variables such as real gross domestic product ("GDP") growth, civilian unemployment rate and West Texas 
Intermediate ("WTI") oil prices on a probability weighted basis. See Note 4 to the Consolidated Financial Statements for 
additional discussion of methodology of allowance for loan losses.

The provision for expected credit losses was $222.6 million for the year ended December 31, 2020. A $234.2 million provision 
related to lending activities was partially offset by a decrease in the accrual for expected credit losses from mortgage banking 
activities and allowance for credit losses from investment securities. During the second quarter of 2020, the Company sold 
certain mortgage servicing rights related to residential mortgage loans transferred to mortgage-backed securities. These 
servicing rights expose the Company to credit risk for amounts that exceed the U.S. government agency guarantees.

Changes in our reasonable and supportable forecasts of macroeconomic variables, primarily due to the anticipated impact of the 
COVID-19 pandemic, resulted in a $99.1 million provision for credit losses from lending activities. Economic conditions were 
volatile during the year, including changes in unemployment rates, GDP and energy commodity prices, causing the 2020 
provision to occur in the first half of the year as our allowance grew for expected losses. While this volatility moderated in the 
latter half of the year, the embedded impact of these risks continue to remain in our portfolio at December 31, 2020. Changes in 
the loan portfolio characteristics, including specific impairment and losses, loan balances and risk grading resulted in a $135.1 
million increase in the provision for credit losses from lending activities during 2020.

We recorded a $6.5 million negative provision for credit losses in the fourth quarter of 2020. Changes in our reasonable and 
supportable forecasts of macroeconomic variables, primarily due to an improved economic outlook related to the anticipated 
impact of the on-going COVID-19 pandemic offset by changes in the probability weighting of the economic scenarios and other 
assumptions, resulted in a $3.0 million increase in the provision for credit losses from lending activities. Changes in the loan 
portfolio characteristics, including specific impairment and losses, risk grading and loan balances resulted in an $8.6 million 
decrease in the provision for credit losses from lending activities.

Our reasonable and supportable forecast of macroeconomic variables is significantly influenced by the COVID-19 pandemic 
developments and related government stimulus policies, which remain highly uncertain. A summary of macroeconomic 
variables considered in developing our estimate of expected credit losses at December 31, 2020 follows:

Trajectory of COVID-19 
maintains current level with 
localized and state-level hotspots 
resulting in isolated shutdowns; 
FDA approval of several more 
vaccines in the first half of 2021, 
with a large share of U.S. 
population vaccinated by the end 
of the third quarter of 2021.

Regional shutdowns and 
consumer confidence weigh 
negatively on economic and 
employment recoveries in the first 
quarter of 2021. As vaccine 
distribution boosts consumer 
confidence, GDP grows at rates 
above historical averages and 
recovers to pre-COVID-19 levels 
by the third quarter of 2021.
No additional fiscal stimulus 
packages are enacted in 2021. 

Trajectory of COVID-19 
continues to improve from peak 
experienced in December of 2020. 
This leads to isolated shutdowns, 
even at a more localized level. 
FDA approval of several more 
vaccines in the first half of 2021, 
with a large share of U.S. 
population vaccinated by the end 
of the third quarter 2021.

Consumer confidence grows as 
optimism around vaccination 
helps maintain moderate growth in 
the first quarter of 2021. GDP 
subsequently continues to grow at 
levels above historical averages,  
recovering to pre-COVID-19 
levels by the second quarter of 
2021.

No additional fiscal stimulus 
packages are enacted in 2021.

Trajectory of COVID-19 
pandemic worsens during winter 
months; additional waves and 
hotspots emerge through the first 
half of 2021. Highly impacted 
states/regions enact shutdowns to 
manage hospital capacity, though 
a nation-wide shutdown is not re-
implemented. FDA does not 
approve additional vaccines until 
the second half of 2021, resulting 
in more protracted distribution and 
delaying widespread vaccination 
in the U.S. until early 2022.
Deteriorated COVID-19 situation, 
slow vaccine distribution and lack 
of fiscal stimulus in 2020 cause 
the economy to fall back into 
recession. GDP does not recover 
to pre-COVID-19 levels until 
early 2023.

Net charge-offs and changes in specific impairments attributed to certain credits required a $75.4 million provision during 2020 
while changes in risk grading during the year resulted in a $92.9 million provision. This provision was partially offset by a 
change in outstanding loan balances used to measure the provision for credit losses related to changes in loan portfolio 
characteristics. A summary of outstanding loan balances by risk grade is included in Note 4 to the Consolidated Financial 
Statements. Non-pass grade loans include other loans especially mentioned, defined by regulatory guidelines as loans that are 
currently performing in compliance with original terms but may have a potential weakness that deserves management’s close 
attention, accruing substandard loans, and nonaccruing loans. Non-pass grade loans totaled $1.0 billion at December 31, 2020, 
composed primarily of $650 million or 19% of energy loans, $133 million or 4% of commercial services loans, $84 million or 
3% of commercial general business loans, $58 million or 1% of commercial real estate loans and $53 million or 2% of 
commercial healthcare loans. Non-pass grade loans totaled $551 million at December 31, 2019.

Although fiscal stimulus through PPP, SBA support and other CARES Act programs have had a positive impact on credit 
quality, we received a number of deferral or forbearance requests beginning in the second quarter of 2020. All requests were 
evaluated on a case-by-case basis and all loans greater than $1 million that requested forbearance were reviewed for proper 
grading. At the peak, deferral requests totaled $1.6 billion or 8% of total loans. At December 31, 2020, loans in deferral status 
have dropped to just below 1% of total loans. More than 90% of the loans that were deferred have now moved back to payment 
status and are making payments pursuant to an updated payment schedule.    

The allowance for loan losses totaled $389 million or 1.69% of outstanding loans and 171% of nonaccruing loans at December 
31, 2020, excluding residential mortgage loans guaranteed by U.S. government agencies. The combined allowance for loan 
losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $426 million or 1.85% of outstanding 
loans and 188% of nonaccruing loans at December 31, 2020. Excluding PPP loans, the allowance for loan losses was 1.82% of 
outstanding loans and the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan 
commitments was 2.00%.

The allowance for credit losses attributed to energy was 3.61% of outstanding energy loans at December 31, 2020. Our most 
recent semi-annual borrowing base redetermination was completed during the fourth quarter of 2020 based on forward pricing 
curves that existed at that time. While forward prices subsequently improved, the pricing environment remains fragile and tied 
to the continued economic recovery from the impact of the COVID-19 pandemic. We believe the duration of the downturn is a 
more significant factor affecting performance than the level of prices. 

We also conduct quarterly stress tests of our energy borrowers with more than 50% funding on their lines of credit and all non-
pass graded loans using a current price deck discounted at 20%. This stress test helps us identify potential issues, although the 
most recent test corroborated the risk grading of energy borrowers evaluated once hedging was taken into consideration. Of all 
the energy customers that we stress test, which makes up 96% of production loans outstanding, 96% of our customers have 
some level of hedging in the 12-month range and many of them carry into the 24-month range. 

The company recorded a $44 million provision for credit losses under the previous incurred loss model in 2019. The allowance 
for loan losses under the incurred loss model was $211 million or 0.97% of outstanding loans and 121% of nonaccruing loans, 
excluding loans guaranteed by U.S. government agencies at December 31, 2019. The combined allowance for loan losses and 
accrual for off-balance sheet credit risk from unfunded loan commitments was $212 million or 0.98% of outstanding loans and 
121% of core nonaccruing loans.

Financial Instruments – Credit Losses (Topic 326): Assets Measured at Amortized Cost ("CECL") on January 1, 2020

Net Loans Charged Off

Net loans charged off totaled $70 million or 0.32% of average loans, excluding PPP loans, in 2020. Net loans charged off were 
$41 million or 0.19% of average loans in 2019. 

In 2020, net charge-offs of commercial loans were $69 million, primarily related to energy borrowers. Net commercial real 
estate loan charge-offs were $1.0 million and net loan charge-offs of loans to individuals were $620 thousand. Net charge-offs 
of loans to individuals include deposit account overdraft losses.

Accrual for Off-Balance Sheet Credit Risk Associated with Mortgage Banking Activities

The accrual for off-balance sheet credit risk associated with mortgage banking activities includes consideration of credit risk 
related to certain residential mortgage loans sold into mortgage-backed securities in excess of amounts guaranteed by the U.S. 
Department of Veteran's Affairs ("VA") and mortgage loans originated under community development loan programs that were 
sold to a U.S. government agency with full recourse.

We use publicly available long-term national data to estimate total loss given default for our off-balance sheet credit risk related 
to losses in excess of amounts guaranteed by the VA. This result is combined with probability of default output from our 
mortgage servicing rights model to estimate total expected loss. Then, we estimate the VA's guarantee percentage to determine 
our portion of the credit risk. Qualitative adjustment may be used, if necessary.

Allowance for Credit Losses Related to Held-to-Maturity (Investment) Securities

The expected credit losses principles apply to all financial assets measured at cost, including our held-to-maturity (investment) 
debt securities portfolio. Our investment portfolio includes municipal and other tax-exempt securities and other debt securities. 
Expected credit losses for these assets is based on probability of default and loss given default assumptions that align with 
similarly graded loans. Qualitative adjustment may be used, if necessary.

Nonperforming Assets

As more fully described in Note 4 to the Consolidated Financial Statements, loans are generally classified as nonaccruing when 
it becomes probable that we will not collect the full contractual principal and interest. Accruing renegotiated loans guaranteed 
by U.S. government agencies represent residential mortgage loans that have been modified in troubled debt restructurings. 
Interest continues to accrue based on the modified terms of the loan and loans may be sold once they become eligible according 
to U.S. government agency guidelines. Real estate and other repossessed assets are assets acquired in partial or total forgiveness 
of loans. The assets are carried at the lower of cost as determined by fair value at the date of foreclosure or current fair value, 
less estimated selling costs. A summary of nonperforming assets follows in Table 26:

2   Excludes residential mortgage and PPP loans guaranteed by U.S. government agencies.
3  Excludes residential mortgages guaranteed by U.S. government agencies.

Excluding assets guaranteed by U.S. government agencies, nonperforming assets increased $122 million over December 31, 
2019, primarily due to a $70 million increase in real estate and other repossessed assets, a $33 million increase in nonaccruing 
energy loans and an $18 million increase in nonaccruing services loans. Newly identified nonaccruing loans totaled $305 
million, partially offset by $85 million of foreclosures, $79 million of charge-offs and $74 million in payments. The Company 
generally retains nonperforming assets to maximize potential recovery, which may cause future nonperforming assets to 
decrease more slowly.

We foreclose on loans guaranteed by U.S. government agencies in accordance with agency guidelines. Generally these loans 
are not eligible for modification programs or have failed to comply with modified loan terms. Principal is guaranteed by 
agencies of the U.S. government, subject to limitations and credit risk is limited. These properties will be conveyed to the 
agencies and receivables collected once applicable criteria have been met. 

Real Estate and Other Repossessed Assets

Real estate and other repossessed assets totaled $91 million at December 31, 2020, composed primarily of $64 million of oil 
and gas properties, including $41 million of repossessed oil & gas properties included in a consolidated limited liability 
corporation that is 60% owned by the Company and 40% owned by an unrelated financial institution. The remaining balance of 
real estate and other repossessed assets included $21 million of developed commercial real estate, $3.4 million of undeveloped 
land primarily zoned for commercial development and $625 thousand of 1-4 family residential properties. The residential 
properties and undeveloped land are widely disbursed across our geographical footprint. Real estate and other repossessed 
assets increased $73 million compared to December 31, 2019. 

Liquidity and Capital

Based on the average balances for 2020, approximately 67% of our funding was provided by deposit accounts, 17% from 
borrowed funds, less than 1% from long-term subordinated debt and 10% from equity. Our funding sources, which primarily 
include deposits and borrowings from the Federal Home Loan Banks, provide adequate liquidity to meet our operating needs.

Subsidiary Bank

Deposits and borrowed funds are the primary sources of liquidity for the subsidiary bank. Deposit accounts represent our largest 
funding source. We compete for retail and commercial deposits by offering a broad range of products and services and focusing 
on customer convenience. Retail deposit growth is supported through personal and small business checking, online bill paying 
services, mobile banking services, an extensive network of branch locations and ATMs and our ExpressBank call 
center. Commercial deposit growth is supported by offering treasury management and lockbox services. We also acquire 
brokered deposits when the cost of funds is advantageous to other funding sources.

Average deposits for 2020 totaled $32.8 billion and represented approximately 67% of total liabilities and capital compared to 
$25.7 billion and 61% of total liabilities and capital for 2019. Average deposits increased $7.1 billion over the prior year. 
Inflows resulting from PPP loans and government stimulus payments during the pandemic, along with additional core deposit 
growth as customers maintain higher balances during the current economic environment, have all contributed to the significant 
increase in deposits. Interest-bearing transaction deposit account balances increased by $5.6 billion and demand deposits grew 
by $1.4 billion. 

Average deposits attributed to Commercial Banking were $14.3 billion for 2020, a $4.0 billion or 39% increase over 2019. 
Interest-bearing transaction account balances increased $2.5 billion or 60% and demand deposit balances increased $1.3 billion
or 22%. Commercial customers continue to retain large cash reserves primarily due to a combination of factors including 
uncertainty about the economic environment and potential for growth, lack of preferable liquid alternatives and a desire to 
minimize deposit charges through the earnings credit. The earnings credit is a non-cash method that enables commercial 
customers to offset deposit service charges based on account balances. Commercial deposit balances may decrease as the 
economic outlook improves and if short-term rates move higher, enhancing their investment alternatives.

Average Consumer Banking deposit balances increased $723 million or 11% over the prior year. Average demand deposit 
balances grew by $470 million or 22% while average interest-bearing transaction accounts increased $253 million or 5%. Time 
deposit balances decreased $15 million or 2%. 

Average Wealth Management deposit balances grew by $2.2 billion or 35% over the prior year. Interest-bearing transaction 
balances increased $2.3 billion or 52%. Non-interest-bearing demand deposits decreased $42 million or 4%, and time deposit 
balances decreased $63 million or 8%.

See Note 9 to the Consolidated Financial Statements for a summary of other borrowings.

In addition to deposits, liquidity for the subsidiary bank is provided primarily by federal funds purchased, securities repurchase 
agreements and Federal Home Loan Bank borrowings. Federal funds purchased consist primarily of unsecured, overnight funds 
acquired from other financial institutions. Funds are primarily purchased from bankers’ banks and Federal Home Loan Banks 
from across the country. The largest source of wholesale federal funds purchased totaled $200 million at December 31, 2020
and $600 million at December 31, 2019. Securities repurchase agreements generally mature within 90 days and are secured by 
certain available for sale securities. Federal Home Loan Bank borrowings are generally short term and are secured by a blanket 
pledge of eligible collateral (generally unencumbered U.S. Treasury and mortgage-backed securities, 1-4 family residential 
mortgage loans, multifamily and other qualifying commercial real estate loans). Amounts borrowed from the Federal Home 
Loan Bank of Topeka averaged $3.4 billion during 2020 and $7.1 billion during 2019.

On April 13, 2020, the banking agencies published an interim final rule which permits banking organizations to exclude from 
regulatory capital requirements PPP covered loans pledged to the Federal Reserve's Paycheck Protection Program Liquidity 
Facility ("PPLF"). The Company initially funded PPP loans from deposits and Federal Home Loan Bank borrowings, but 
transitioned to the PPLF in June of 2020 in order to realize this regulatory capital relief.

At December 31, 2020, the estimated unused credit available to BOKF, NA from collateralized sources was approximately 
$16.5 billion.

BOKF, NA also has a liability related to the repurchase of certain delinquent residential mortgage loans previously sold in 
GNMA mortgage pools. Interest is payable monthly at rates contractually due to investors. The average balance of this liability 
increased over the prior year primarily due to GNMA loans serviced by the Company that are participating in the forbearance 
program included in the CARES Act, which began in the second quarter. As delinquencies increase, the GNMA repurchase 
liability will also increase.

Parent Company and Other Non-Bank Subsidiaries

The primary sources of liquidity for BOK Financial are cash on hand and dividends from the subsidiary bank. Cash and cash 
equivalents totaled $184 million at December 31, 2020. Dividends from the subsidiary bank are limited by various banking 
regulations to net profits, as defined, for the year plus retained profits for the two preceding years. Dividends are further 
restricted by minimum capital requirements. At December 31, 2020, based on the most restrictive limitations as well as 
management’s internal capital policy, BOKF, NA could declare up to $370 million of dividends without regulatory 
approval. Dividend constraints may be alleviated through increases in retained earnings, capital issuances or changes in risk 
weighted assets. Future losses or increases in required regulatory capital could also affect its ability to pay dividends to the 
parent company. 

On June 27, 2016, the parent company issued $150 million of subordinated debt that will mature on June 30, 2056. This debt 
bears interest at the rate of 5.375%, payable quarterly. On June 30, 2021, we will have the option to redeem the debt at the 
principal amount plus accrued interest, subject to regulatory approval.

As a result of the acquisition of CoBiz Financial, we obtained $60 million of subordinated debt issued in June 2015 that will 
mature on June 25, 2030. This debt bears interest at the rate of 5.625% through June 25, 2025 and thereafter, the notes will bear 
an annual floating rate equal to 3-month LIBOR plus 317 basis points. We also acquired $72 million of junior subordinated 
debentures. Interest is based on spreads over 3 month LIBOR ranging from 145 basis points to 295 basis points and mature 
September 17, 2033 through September 30, 2035. The junior subordinated debentures are subject to early redemption prior to 
maturity.

Shareholders' equity at December 31, 2020 was $5.3 billion, an increase of $410 million over December 31, 2019. Net income 
less cash dividends paid increased equity $357 million during 2020. Changes in interest rates resulted in accumulated other 
comprehensive income of $336 million at December 31, 2020, compared to $105 million at December 31, 2019. Capital is 
managed to maximize long-term value to the shareholders. Factors considered in managing capital include projections of future 
earnings, asset growth and acquisition strategies, and regulatory and debt covenant requirements. Capital management may 
include subordinated debt issuance, share repurchase and stock and cash dividends. 

On April 30, 2019, the Board of Directors authorized the Company to purchase up to five million common shares, subject to 
market conditions, securities laws and other regulatory compliance limitations. As of December 31, 2020, a cumulative total of 
1,973,813 shares have been repurchased under this authorization. The Company repurchased 1,107,100 shares during 2020 at 
an average price of $68.49 per share.

BOK Financial and the subsidiary bank are subject to various capital requirements administered by federal agencies. Failure to 
meet minimum capital requirements, including capital conservation buffer, can result in certain mandatory and additional 
discretionary actions by regulators that could have a material impact on operations including restrictions on capital distributions 
from dividends and share repurchases and executive bonus payments. These capital requirements include quantitative measures 
of assets, liabilities and off-balance sheet items. The capital standards are also subject to qualitative judgments by the 
regulators.

A summary of minimum capital requirements follows for BOK Financial on a consolidated basis in Table 32.

In March 2020, in response to the impact on the financial markets by the COVID-19 pandemic, the banking agencies issued an 
interim final rule permitting banking organizations that implement CECL the option to delay for two years an estimate of the 
CECL methodology's effect on regulatory capital, followed by a three-year transition period. The estimate includes the 
implementation date adjustment as of January 1, 2020 plus an estimate of the impact of the change for a two year period 
following implementation of CECL. We have elected to delay the regulatory capital impact of the transition in accordance with 
the interim final rule. Deferral of the impact of CECL added 26 basis points to the Company's Common equity Tier 1 capital at 
December 31, 2020.

Capital resources of financial institutions are also regularly measured by the tangible common shareholders’ equity 
ratio. Tangible common shareholders’ equity is shareholders’ equity as defined by generally accepted accounting principles in 
the United States of America (“GAAP”), including unrealized gains and losses on available for sale securities, less intangible 
assets and equity which does not benefit common shareholders. Equity that does not benefit common shareholders includes 
preferred equity. This non-GAAP measure is a valuable indicator of a financial institution’s capital strength since it eliminates 
intangible assets from shareholders’ equity and retains the effect of unrealized losses on securities and other components of 
accumulated other comprehensive income in shareholders’ equity.

Table 33 following provides a reconciliation of the non-GAAP measures with financial measures defined by GAAP.

Payments on time deposits, other borrowed funds and subordinated debentures include interest which has been calculated from 
rates at December 31, 2020. These obligations may have variable interest rates and actual payments will differ from the 
amounts shown on this table. 

Payments on time deposits are based on contractual maturity dates. These funds may be withdrawn prior to maturity. We may 
charge the customer a penalty for early withdrawal.

Lease commitments generally represent real property we rent for branch offices, corporate offices and operations 
facilities. Payments presented represent the minimum lease payments and exclude related costs such as utilities and property 
taxes.

Obligations under derivative contracts are used in customer hedging programs. As previously discussed, we have entered into 
derivative contracts which are expected to substantially offset the cash payments due on these obligations. 

Data processing and communications contracts represent the minimum obligations under the contracts. Additional payments 
that are based on the volume of transactions processed are excluded.

Loan commitments represent legally binding obligations to provide financing to our customers. Some of these commitments are 
expected to expire before being drawn upon and the total commitment amounts do not necessarily represent future cash 
requirements. Approximately $2.1 billion of the loan commitments expire within one year.

The Company has commitments to fund an additional $94 million for various alternative investments. Alternative investments 
primarily consist of limited partnership interests in entities that invest in low income housing projects. Legally binding 
commitments to fund alternative investments are recognized as liabilities in the Consolidated Financial Statements.

Forward-Looking Statements

This 10-K contains forward-looking statements that are based on management's beliefs, assumptions, current expectations, 
estimates and projections about BOK Financial, the financial services industry, the economy generally and the expected or 
potential impact of the novel coronavirus (COVID-19) pandemic, and the related responses of the government, consumers, and 
others, on our business, financial condition and results of operations. Words such as “anticipates,” “believes,” “estimates,” 
“expects,” “forecasts,” “plans,” “projects,” “will,” “intends,” variations of such words and similar expressions are intended to 
identify such forward-looking statements. Management judgments relating to and discussion of the provision and allowance for 
credit losses, allowance for uncertain tax positions, accruals for loss contingencies and valuation of mortgage servicing rights 
involve judgments as to expected events and are inherently forward-looking statements. Assessments that acquisitions and 
growth endeavors will be profitable are necessary statements of belief as to the outcome of future events based in part on 
information provided by others which BOK Financial has not independently verified. These various forward-looking statements 
are not guarantees of future performance and involve certain risks, uncertainties, and assumptions which are difficult to predict 
with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ 
from what is expected, implied or forecasted in such forward-looking statements. Internal and external factors that might cause 
such a difference include, but are not limited to changes in government, consumer or business responses to, and ability to treat 
or prevent further outbreak of, the COVID-19 pandemic, commodity prices, interest rates and interest rate relationships, 
inflation, demand for products and services, the degree of competition by traditional and nontraditional competitors, changes in 
banking regulations, tax laws, prices, levies and assessments, the impact of technological advances, and trends in customer 
behavior as well as their ability to repay loans. BOK Financial and its affiliates undertake no obligation to update, amend or 
clarify forward-looking statements, whether as a result of new information, future events, or otherwise.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

Market risk is a broad term for the risk of economic loss due to adverse changes in the fair value of a financial instrument. 
These changes may be the result of various factors, including interest rates, foreign exchange rates, commodity prices or equity 
prices. Financial instruments that are subject to market risk can be classified either as held for trading or held for purposes other 
than trading. Market risk excludes changes in fair value due to credit of the individual issuers of financial instruments.

BOK Financial is subject to market risk primarily through the effect of changes in interest rates on both its assets held for 
purposes other than trading and trading assets. The effects of other changes, such as foreign exchange rates, commodity prices 
or equity prices do not pose significant market risk to BOK Financial. BOK Financial has no material investments in assets that 
are affected by changes in foreign exchange rates or equity prices. Energy and agricultural product derivative contracts, which 
are affected by changes in commodity prices, are matched against offsetting contracts as previously discussed.

The Asset/Liability Committee is responsible for managing market risk in accordance with policy limits established by the 
Board of Directors. The Committee monitors projected variation in net interest revenue, net income and economic value of 
equity due to specified changes in interest rates. These limits also set maximum levels for short-term borrowings, short-term 
assets, public funds and brokered deposits and establish minimum levels for un-pledged assets, among other things. Further, the 
Board approved market risk limits for fixed income trading, mortgage pipeline and mortgage servicing assets inclusive of 
economic hedge benefits. Exposure is measured daily and compliance is reviewed monthly. Deviations from the Board 
approved limits, which periodically occur throughout the reporting period, may require management to develop and execute 
plans to reduce exposure. These plans are subject to escalation to and approval by the Board.

The simulations used to manage market risk are based on numerous assumptions regarding the effects of changes in interest 
rates on the timing and extent of repricing characteristics, future cash flows and customer behavior. These assumptions are 
inherently uncertain and, as a result, models cannot precisely estimate or precisely predict the impact of higher or lower interest 
rates. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes, market 
conditions and management strategies, among other factors.

Interest Rate Risk – Other than Trading

As previously noted in the Net Interest Revenue section of this report, management has implemented strategies to manage the 
Company’s balance sheet to have relatively limited exposure to changes in interest rates over a twelve-month period. The 
effectiveness of these strategies in managing the overall interest rate risk is evaluated through the use of an asset/liability 
model. BOK Financial performs a sensitivity analysis to identify more dynamic interest rate risk exposures, including 
embedded option positions, on net interest revenue. A simulation model is used to estimate the effect of changes in interest rates 
on our performance across multiple interest rate scenarios. Our current internal policy limit for net interest revenue variation 
due to a 200 basis point parallel change in market interest rates over twelve months is a maximum decline of 5%. The results of 
a decrease in interest rates in the current low-rate environment are not meaningful. 

The Company’s primary interest rate exposures include the Federal Funds rate, which affects short-term borrowings, and the 
prime lending rate and LIBOR, which are the basis for much of the variable rate loan pricing. Additionally, residential 
mortgage rates directly affect the prepayment speeds for residential mortgage-backed securities and mortgage servicing 
rights. Derivative financial instruments and other financial instruments used for purposes other than trading are included in this 
simulation. In addition, the impact on the level and composition of demand deposit accounts and other core deposit balances 
resulting from a significant increase in short-term market interest rates and the overall interest rate environment is likely to be 
material. The simulation incorporates assumptions regarding the effects of such changes based on a combination of historical 
analysis and expected behavior. The impact of planned growth and new business activities is factored into the simulation 
model.

1  Repricing assumptions for non-maturity deposits were updated in the second quarter of 2020 to better represent observed historical performance.
2  The results of a decrease in the current low-rate environment in 2020 are not meaningful. The results of a 200 basis point decrease in interest rates in the low-

rate environment in 2019 were not meaningful, therefore we reported the effect of a 100 basis point decrease in interest rates.

BOK Financial is also subjected to market risk through changes in the fair value of mortgage servicing rights. Changes in the 
fair  value  of  mortgage  servicing  rights  are  highly  dependent  on  changes  in  primary  mortgage  rates  offered  to  borrowers, 
intermediate-term  interest  rates  that  affect  the  value  of  custodial  funds,  and  assumptions  about  servicing  revenues,  servicing 
costs and discount rates. As primary mortgage rates increase, prepayment speeds slow and the value of our mortgage servicing 
rights  increases.  As  primary  mortgage  rates  fall,  prepayment  speeds  increase  and  the  value  of  our  mortgage  servicing  rights 
decreases.

We maintain a portfolio of financial instruments, which may include debt securities issued by the U.S. government or its 
agencies and interest rate derivative contracts held as an economic hedge of the changes in the fair value of our mortgage 
servicing rights. Composition of this portfolio will change based on our assessment of market risk. Changes in the fair value of 
residential mortgage-backed securities are highly dependent on changes in secondary mortgage rates required by investors, and 
interest rate derivative contracts are highly dependent on changes in other market interest rates. While primary and secondary 
mortgage rates generally move in the same direction, the spread between them may widen and narrow due to market conditions 
and government intervention. Changes in the forward-looking spread between the primary and secondary rates can cause 
significant earnings volatility. 

Management performs a stress test to measure market risk due to changes in interest rates inherent in its MSR portfolio and 
hedges. The stress test shocks applicable interest rates up and down 50 basis points and calculates an estimated change in fair 
value, net of economic hedging activity, that may result. The Board has approved a $20 million market risk limit for mortgage 
servicing rights, net of economic hedges.

The Company bears market risk by originating residential mortgages held for sale ("RMHFS"). RMHFS are generally 
outstanding for 60 to 90 days, which represents the typical period from commitment to originate a loan to sale of the closed 
loan to an investor. Primary mortgage interest rate changes during this period affect the value of RMHFS commitments and 
loans. We use forward sale contracts to mitigate market risk on all closed mortgage loans held for sale and on an estimate of 
mortgage loan commitments that are expected to result in closed loans. 

A variety of methods are used to monitor market risk of mortgage origination activities. These methods include daily marking 
of all positions to market value, independent verification of inventory pricing, and revenue sensitivity limits. 

Management performs a stress test to measure market risk due to changes in interest rates inherent in the mortgage production 
pipeline. The stress test shocks applicable interest rates up and down 50 basis points and calculates an estimated change in fair 
value, net of economic hedging activity that may result. The Board has approved a $7 million market risk limit for the mortgage 
production pipeline, net of forward sale contracts.

BOK Financial enters into trading activities both as an intermediary for customers and for its own account. As an intermediary, 
we take positions in securities, generally residential mortgage-backed securities, government agency securities and municipal 
bonds. These securities are purchased for resale to customers, which include individuals, corporations, foundations and 
financial institutions. On a limited basis, we may also take trading positions in U.S. Treasury securities, residential mortgage-
backed securities, and municipal bonds to enhance returns on securities portfolios. Both of these activities involve interest rate, 
liquidity and price risk. BOK Financial has an insignificant exposure to foreign exchange risk and does not take positions in 
commodity derivatives.

A variety of methods are used to monitor the interest rate risk of trading activities. These methods include daily marking of all 
positions to market value, independent verification of inventory pricing, and position limits for each trading activity. Economic 
hedges in either the futures or cash markets may be used to reduce the risk associated with some trading programs.

Management performs a stress test to measure market risk from changes in interest rates on its trading portfolio. The stress test 
shocks applicable interest rates up and down 50 basis points and calculates an estimated change in fair value, net of economic 
hedging activity that may result. The Board has approved an $8 million market risk limit for the trading portfolio, net of 
economic hedges.

Report of Management on Internal Control over Financial Reporting

Management of BOK Financial Corporation is responsible for establishing and maintaining adequate internal control over 
financial reporting and for assessing the effectiveness of internal control over financial reporting, as such term is defined in 
Exchange Act Rules 13a-15(f) and 15d-15(f), as amended. Management has assessed the effectiveness of the Company’s

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of BOK Financial Corporation 

Opinion on Internal Control over Financial Reporting 

We have audited BOK Financial Corporation’s internal control over financial reporting as of December 31, 2020, based on 
criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (2013 framework) (the COSO criteria). In our opinion, BOK Financial Corporation (the Company) 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the 
COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of BOK Financial Corporation as of December 31, 2020 and 2019, and the related 
consolidated statements of earnings, comprehensive income, changes in equity, and cash flows for each of the three years in the 
period ended December 31, 2020, and the related notes and our report dated February 24, 2021 expressed an unqualified 
opinion thereon.

Basis for Opinion 

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion.

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

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

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of BOK Financial Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of BOK Financial Corporation (the Company) as of December 
31, 2020 and 2019, and the related consolidated statements of earnings, comprehensive income, changes in equity, and cash 
flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the 
“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, 
the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for 
each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting 
principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on the criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(2013 framework), and our report dated February 24, 2021 expressed an unqualified opinion thereon.

Adoption of New Accounting Standard

As discussed in Notes 1 and 4 to the consolidated financial statements, the Company changed its method for accounting for 
credit losses in 2020. As explained below, auditing the Company’s allowance for credit losses, including adoption of the new 
accounting guidance related to the estimate of allowance for credit losses, was a critical audit matter. 

Basis for Opinion

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

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

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that 
was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that 
are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The 
communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken 
as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit 
matter or on the accounts or disclosures to which it relates.

Description of 
the Matter

Allowance for credit losses
The Company’s loan portfolio totaled $23.0 billion as of December 31, 2020, and the 
associated allowance for credit losses (ACL) was $425.6 million. The provision for credit 
losses was $234.2 million for the year ended December 31, 2020. As discussed above and in 
Notes 1 and 4, the Company adopted new accounting guidance related to the estimate of the 
allowance for credit losses (ACL or allowance), resulting in a pre-tax cumulative-effect 
decrease to equity of $61.4 million. As discussed in Note 1 and 4 to the consolidated financial 
statements, management’s estimate for the expected credit losses within the loan portfolio 
represents the portion of amortized cost basis of loans and related unfunded commitments 
they do not expect to collect over the asset’s contractual life, considering past events, current 
conditions, as well as reasonable and supportable forecasts of future economic conditions. The 
allowance for credit losses consists of specific allowances attributed to certain individual 
loans, generally nonaccruing loans, with dissimilar risk characteristics that have not yet been 
charged down to amounts they expect to recover, general allowances for estimated credit 
losses on pools of loans that share similar risk characteristics, and qualitative reserves with the 
estimated impact of factors that are not captured in the modeled results or historical 
experience.  

Auditing management’s estimate of the ACL and related provision for credit losses was 
complex due to the allowance models used, high degree of subjectivity in evaluating 
management’s development of forecasts of future economic conditions (“economic 
scenarios”), probability weighting of economic scenarios, and qualitative reserves used in the 
general allowance.      

How We 
Addressed the 
Matter in Our 
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of 
internal controls over the ACL process, including, among others, controls over the 
development, operation, and monitoring of economic scenarios, probability weighting of 
economic scenarios and qualitative reserves used in the allowance results.  

We involved EY specialists in testing management’s models including evaluating model 
methodology, model performance and testing key modeling assumptions as well as controls 
covering the economic scenarios used by the ACL models.  Additionally, with the support of 
EY specialists, we assessed the economic scenarios and related probability weights by 
evaluating management’s methodology and agreeing a sample of key economic variables used 
to external sources. We also performed various sensitivity analyses and analytical procedures, 
including comparison of a sample of the key economic variables to alternative external 
sources and historical statistics.   

With respect to general ACL models, with the support of EY specialists, we evaluated model 
design and re-performed the calculation for a sample of models. We also tested the 
appropriateness of key inputs and assumptions used in these models by agreeing a sample of 
inputs to internal sources.

80

We evaluated the overall ACL amount, including model estimates, qualitative reserves, and 
whether the recorded ACL appropriately reflects expected credit losses. We performed 
analytical procedures on the ACL, charge-off and delinquency rates, and coverage ratios of 
the allowance. Our audit response also included specific substantive tests of management’s 
process to measure qualitative reserves, including those related to the significant judgments 
made by management. We compared calculations to industry peer data and compared 
qualitative reserves to prior periods and prior economic cycles. We also evaluated if the 
qualitative reserves were applied based on a comprehensive framework and that all available 
information was considered, well-documented, and consistently applied. We searched for and 
evaluated information that corroborates or contradicts management’s economic scenarios and 
related probability weights as well as identification and measurement of qualitative reserves.

Notes to Consolidated Financial Statements

(1) Significant Accounting Policies 

Basis of Presentation

The Consolidated Financial Statements of BOK Financial Corporation (“BOK Financial” or “the Company”) have been 
prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"), including 
interpretations of U.S. GAAP issued by federal banking regulators and general practices of the banking industry. The 
Consolidated Financial Statements include the accounts of BOK Financial and its subsidiaries, principally BOKF, NA, BOK 
Financial Securities, Inc., BOK Financial Private Wealth, Inc., BOK Financial Insurance, Inc. and Cavanal Hill Distributors, 
Inc. All significant intercompany transactions are eliminated in consolidation. 

The Consolidated Financial Statements include the assets, liabilities, non-controlling interests and results of operations of 
variable interest entities (“VIEs”) when BOK Financial is determined to be the primary beneficiary. Variable interest entities 
are generally defined as entities that either do not have sufficient equity to finance their activities without support from other 
parties or whose equity investors lack a controlling financial interest. Determination that the Company is the primary 
beneficiary considers the power to direct the activities that most significantly impact the variable interest's economic 
performance and the obligation to absorb losses of the variable interest or the right to receive benefits of the variable interest 
that could be significant to the variable interest.

Certain prior year amounts have been reclassified to conform to current year presentation. 

Nature of Operations

BOK Financial, through its subsidiaries, provides a wide range of financial services to commercial and industrial customers, 
other financial institutions, municipalities, and consumers. These services include depository and cash management; lending 
and lease financing; mortgage banking; securities brokerage, trading and underwriting; and personal and corporate trust.

BOKF, NA operates as Bank of Oklahoma primarily in the Tulsa and Oklahoma City metropolitan areas of the state of 
Oklahoma and Bank of Texas primarily in the Dallas, Fort Worth and Houston metropolitan areas of the state of Texas. In 
addition, BOKF, NA does business as BOK Financial in the metropolitan areas of Phoenix, Arizona; Northwest Arkansas; 
Denver, Colorado; Kansas City, Missouri/Kansas; and as Bank of Albuquerque in Albuquerque, New Mexico. BOKF, NA also 
operates the TransFund electronic funds network, Cavanal Hill Investment Management, and BOK Financial Asset 
Management, Inc.

Use of Estimates

Preparation of BOK Financial's Consolidated Financial Statements requires management to make estimates of future economic 
activities, including loan collectability, loss contingencies, prepayments and cash flows from customer accounts. These 
estimates are based upon current conditions and information available to management. Actual results may differ significantly 
from these estimates.

Acquisitions

Assets and liabilities acquired, including identifiable intangible assets, are recorded at fair value on the acquisition date. The 
purchase price includes consideration paid at closing and the estimated fair value of contingent consideration that will be paid in 
the future, subject to achieving defined performance criteria. Premiums and discounts assigned to interest-earning assets and 
interest-bearing liabilities are amortized over the lives of the acquired assets and liabilities on either an individual instrument or 
pool basis. Provision for credit losses is recognized for changes in credit quality after the acquisition date. Goodwill is 
recognized as the excess of the purchase price over the net fair value of assets acquired and liabilities assumed. The 
Consolidated Statements of Earnings include the results of operations from the acquisition date.

88

 
 
Goodwill and Intangible Assets

Goodwill and intangible assets generally result from business combinations and are evaluated for each of BOK Financial's 
reporting units for impairment annually or more frequently if conditions indicate impairment. The evaluation of possible 
impairment of goodwill and intangible assets involves significant judgment based upon short-term and long-term projections of 
future performance.

Reporting units are defined by the Company as significant lines of business within each operating segment. This definition is 
consistent with the manner in which the chief operating decision maker assesses the performance of the Company and makes 
decisions concerning the allocation of resources. The Company qualitatively assesses whether it is more likely than not that the 
fair value of the reporting units are less than their carrying value, including goodwill. Reporting unit carrying value includes 
sufficient capital to exceed regulatory requirements. This assessment includes consideration of relevant events and 
circumstances including but not limited to macroeconomic conditions, industry and market conditions, the financial and stock 
performance of the Company and other relevant factors.

If the Company concludes based on the qualitative assessment that goodwill may be impaired, a quantitative one-step 
impairment test will be applied to goodwill at all reporting units. The quantitative analysis compares the fair value of the 
reporting unit with its carrying value, including goodwill. The fair value of each reporting unit is estimated by the discounted 
future earnings method. Goodwill is considered impaired if the fair value of the reporting unit is less than the carrying value of 
the reporting unit, including goodwill.

Intangible assets are generally composed of customer relationships, naming rights, non-compete agreements and core deposit 
premiums. They are amortized using accelerated or straight-line methods, as appropriate, over the estimated benefit periods. 
These periods range from 3 years to 20 years. The net book values of identifiable intangible assets are evaluated for impairment 
when economic conditions indicate impairment may exist.

Cash Equivalents

Due from banks, funds sold (generally federal funds sold for one day), resell agreements (which generally mature within one 
day to 30 days) and investments in money market funds are considered cash equivalents.

Securities

Securities are identified as trading, investment (held to maturity) or available for sale at the time of purchase based upon the 
intent of management, liquidity and capital requirements, regulatory limitations and other relevant factors. Trading securities, 
which are acquired for profit through resale, are carried at fair value with unrealized gains and losses included in current period 
earnings. Investment securities are carried at amortized cost. Amortization is computed by methods that approximate level yield 
and is adjusted for changes in prepayment estimates. Securities identified as available for sale are carried at fair value. 
Unrealized gains and losses are recorded, net of deferred income taxes, as accumulated other comprehensive income in 
shareholders' equity. Available for sale securities are separately identified as pledged to creditors if the creditor has the right to 
sell or re-pledge the collateral.

The purchase or sale of securities is recognized on a trade date basis. Realized gains and losses on sales of securities are based 
upon specific identification of the security sold. A receivable or payable is recognized for subsequent transaction settlement. 

On a quarterly basis, the Company performs separate evaluations of debt investment and available for sale securities for the 
presence of impairment. We assess whether impairment is present on an individual security basis when the fair value of a debt 
security is less than the amortized cost. 

Management determines whether it intends to sell or if it is more likely than not that it will be required to sell impaired 
securities. This determination considers current and forecasted liquidity requirements and securities portfolio management. If 
the Company intends to sell or it is more likely than not that it will be required to sell the impaired debt security, a charge is 
recognized against earnings for the entire unrealized loss. For all impaired debt securities for which there is no intent or 
expected requirement to sell, the evaluation considers all available evidence to assess whether it is more likely than not that all 
amounts due would not be collected according to the security's contractual terms and whether there is any impairment 
attributable to credit-related factors. If an impairment exists, the amount attributed to credit-related factors is measured and an 
allowance for credit loss is recognized. Declines in fair value that are not recorded in the allowance are recorded in other 
comprehensive income, net of taxes.

89

 
 
 
 
 
BOK Financial may elect to carry certain securities that are not held for trading purposes at fair value with changes in fair value 
recognized in current period income. These securities are held with the intent that gains or losses will offset changes in the fair 
value of mortgage servicing rights or other financial instruments.

Restricted equity securities represent equity interests the Company is required to hold in the Federal Reserve Banks and Federal 
Home Loan Banks. Restricted equity securities are carried at cost as these securities do not have a readily determined fair value 
because ownership of these shares is restricted and they lack a market.

The fair value of our securities portfolio is generally based on a single price for each financial instrument provided to us by a 
third-party pricing service determined by one or more of the following:

•
•
•

•

Quoted prices for similar, but not identical, assets or liabilities in active markets;
Quoted prices for identical or similar assets or liabilities in inactive markets;
Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment 
speeds, loss severities, credit risks and default rates; and
Other inputs derived from or corroborated by observable market inputs.

The underlying methods used by the third-party pricing services are considered in determining the primary inputs used to 
determine fair values. We evaluate the methodologies employed by the third-party pricing services by comparing the price 
provided by the pricing service with other sources, including brokers' quotes, sales or purchases of similar instruments and 
discounted cash flows to establish a basis for reliance on the pricing service values. Significant differences between the pricing 
service provided value and other sources are discussed with the pricing service to understand the basis for their values. Based 
on all observable inputs, management may adjust prices obtained from third-party pricing services to more appropriately reflect 
the prices that would be received to sell assets or paid to transfer liabilities in orderly transactions in the current market. 

Derivative Instruments

Derivative instruments may be used by the Company as part of its internal risk management programs or may be offered to 
customers. All derivative instruments are carried at fair value and changes in fair value are generally reported in income as they 
occur. The determination of fair value of derivative instruments considers changes in interest rates, commodity prices and 
foreign exchange rates. Fair values for exchange-traded contracts are based on quoted prices in an active market for identical 
instruments. Fair values for over-the-counter contracts are generated internally using third-party valuation models. Inputs used 
in third-party valuation models to determine fair values are considered significant other observable inputs. Credit risk is also 
considered in determining fair value. Deterioration in the credit rating of customers or other counterparties reduces the fair 
value of asset contracts. Deterioration of our credit rating could decrease the fair value of our derivative liabilities. 

When bilateral netting agreements or similar agreements exist between the Company and its counterparties that create a single 
legal claim or obligation to pay or receive the net amount in settlement of the individual derivative contracts, the Company 
reports derivative assets and liabilities on a net by derivative contract by counterparty basis.

Derivative contracts may also require the Company to provide or receive cash margin as collateral for derivative assets and 
liabilities. Derivative assets and liabilities are reported net of cash margin when certain conditions are met. In addition, 
derivative contracts executed with customers under Customer Risk Management Programs may be secured by non-cash 
collateral in conjunction with a credit agreement with that customer. Access to collateral in the event of default is reasonably 
assured.

BOK Financial offers programs that permit its customers to manage various risks, including fluctuations in energy, cattle and 
other agricultural products, interest rates and foreign exchange rates with derivative contracts. Customers may also manage 
interest rate risk through interest rate swaps used by the borrower to modify interest rate terms of their loans. Derivative 
contracts are executed between the customers and BOK Financial. Offsetting contracts are executed between BOK Financial 
and other selected counterparties to minimize market risk from changes in commodity prices, interest rates or foreign exchange 
rates. The counterparty contracts are identical to customer contracts, except for a fixed pricing spread or fee paid to BOK 
Financial as profit and compensation for administrative costs and credit risk which is recognized over the life of the contracts 
and included in Other Operating Revenue - Brokerage and trading revenue in the Consolidated Statements of Earnings.

BOK Financial may offer derivative instruments such as to-be-announced U.S. agency residential mortgage-backed securities to 
mortgage banking customers to enable them to manage their market risk or to mitigate the Company's market risk of holding 
trading securities. Changes in the fair value of derivative instruments for trading purposes or used to mitigate the market risk of 
holding trading securities are included in Other Operating Revenue - Brokerage and trading revenue.

BOK Financial may use derivative instruments in managing its interest rate sensitivity, as part of its economic hedge of the 
changes in the fair value of mortgage servicing rights. Changes in the fair value of derivative instruments used in managing 
interest rate sensitivity and as part of its economic hedge of changes in the fair value of mortgage servicing rights are included 
in Other Operating Revenue - Gain (loss) on derivatives, net in the Consolidated Statements of Earnings. 

BOK Financial also enters into mortgage loan commitments that are considered derivative contracts. Forward sales contracts 
that have not been designated as hedging instruments are used to economically hedge these mortgage loan commitments as well 
as mortgage loans held for sale. Mortgage loan commitments, forward sales contracts, and residential mortgage loans held for 
sale are carried at fair value. Changes in the fair value are reported in Other Operating Revenue - Mortgage banking revenue.

Loans

Loans are either secured or unsecured based on the type of loan and the financial condition of the borrower. Repayment is 
generally expected from cash flow or proceeds from the sale of selected assets of the borrower. BOK Financial is exposed to 
risk of loss on loans due to the borrower's financial difficulties, which may arise from any number of factors, including 
problems within the respective industry or local economic conditions. Access to collateral, in the event of borrower default, is 
reasonably assured through adherence to applicable lending laws and through sound lending standards and credit review 
procedures. Accounting policies for all loans, excluding residential mortgage loans guaranteed by U.S. government agencies, 
are as follows.

Interest is accrued at the applicable interest rate on the outstanding principal amount. Loans are placed on nonaccruing status 
when, in the opinion of management, full collection of principal or interest is uncertain. Internally risk graded loans are 
individually evaluated for nonaccruing status quarterly. Non-risk graded loans are generally placed on nonaccruing status when 
90 days or more past due or within 60 days of being notified of the borrower's bankruptcy filing. Interest previously accrued but 
not collected is charged against interest income when the loan is placed on nonaccruing status. Payments received on 
nonaccruing loans are applied to principal or recognized as interest income, according to management's judgment as to the 
collectability of principal. Loans may be returned to accruing status when, in the opinion of management, full collection of 
principal and interest, including principal previously charged off, is probable based on improvements in the borrower's financial 
condition or a sustained period of performance. 

For loans acquired with no evidence of credit deterioration, discounts are accreted on either an individual basis for loans with 
unique characteristics or on a pool basis for groups of homogeneous loans. Accretion is discontinued when a loan with an 
individually attributed discount is placed on nonaccruing status.

Loans to borrowers experiencing financial difficulties may be modified in troubled debt restructurings ("TDRs"). TDRs are 
generally classified as nonaccruing, excluding loans guaranteed by U.S. government agencies. Modifications generally consist 
of extension of payment terms or interest rate concessions and may result either voluntarily through negotiations with the 
borrower or involuntarily through court order. Payment deferrals of up to six months are generally considered to be short-term 
modifications. Generally, principal and accrued but unpaid interest is not voluntarily forgiven. 

Performing loans may be renewed under the then current collateral, debt service ratio and other underwriting standards. 
Nonaccruing loans may also be renewed and will remain classified as nonaccruing.

Occasionally, loans, other than residential mortgage loans, may be held for sale in order to manage credit concentration. These 
loans are carried at the lower of cost or fair value with gains or losses recognized in gain (loss) on assets.  

All loans are charged-off when the loan balance or a portion of the loan balance is no longer supported by the paying capacity 
of the borrower or when the required cash flow is reduced in a TDR. The charge-off amount is determined through an 
evaluation of available cash resources and collateral value. Internally risk graded loans are evaluated quarterly and charge-offs 
are taken in the quarter in which the loss is identified. Non-risk graded loans that are past due between 60 days and 180 days, 
based on the loan product type, are charged off. Loans to borrowers whose personal obligation has been discharged through 
Chapter 7 bankruptcy proceedings are charged off within 60 days of notice of the bankruptcy filing, regardless of payment 
status.

Loan origination and commitment fees and direct loan acquisition and origination costs are deferred and amortized as an 
adjustment to yield over the life of the loan or over the commitment period, as applicable. Amortization does not anticipate loan 
prepayments. Net unamortized fees are recognized in full at time of payoff.

91

 
Qualifying residential mortgage loans guaranteed by U.S. government agencies have been sold into GNMA pools. Under 
certain performance conditions specified in government programs, the Company has the right, but not the obligation to 
repurchase loans from GNMA pools. These loans no longer qualify for sale accounting and are recognized in the Consolidated 
Balance Sheets. Guaranteed loans are considered to be impaired because we do not expect to receive all principal and interest 
based on the loan's contractual terms. A portion of the principal balance continues to be guaranteed; however, interest accrues at 
a curtailed rate as specified in the programs. The carrying value of these loans is reduced based on an estimate of expected cash 
flows discounted at the original note rate plus a liquidity spread. Guaranteed loans may be modified in TDRs in accordance 
with U.S. government agency guidelines. Interest continues to accrue at the modified rate. Guaranteed loans may either be 
resold into GNMA pools after a performance period specified by the programs or foreclosed and conveyed to the guarantors.

Loans are disaggregated into portfolio segments and further disaggregated into classes. The portfolio segment is the level at 
which the Company develops and documents a systematic method for determining its Allowance for Credit Losses. Classes are 
based on the risk characteristics of the loans and the Company's method for monitoring and assessing credit risk.

Allowances for Credit Losses and Accrual for Off-balance Sheet Credit Risk from Unfunded Loans Commitments

BOK Financial’s accounting policies have changed significantly with the adoption of CECL as of January 1, 2020. Prior 
periods are not restated. Prior to January 1, 2020, general allowances and nonspecific allowances were based on incurred credit 
losses in accordance with accounting policies disclosed in Note 1 of the Consolidated Financial Statements included in the 2019 
Form 10-K.

The allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments represent the 
portion of the amortized cost basis of loans that we do not expect to collect over the asset’s contractual life, considering past 
events, current conditions, and reasonable and supportable forecasts of future economic conditions. The appropriateness of the 
allowance for credit losses, including industry and product adjustments, is assessed quarterly by a senior management 
Allowance Committee. This review is based on an on-going evaluation of the estimated expected credit losses in the portfolio 
and on unused commitments to provide financing. A well-documented methodology has been developed and is applied by an 
independent Credit Administration department to assure consistency across the Company.  

The allowance for loan losses consists of specific allowances attributed to certain individual loans, generally nonaccruing loans, 
with dissimilar risk characteristics that have not yet been charged down to amounts we expect to recover and general 
allowances for estimated credit losses on pools of loans that share similar risk characteristics.  

When full collection of principal or interest is uncertain, the loan’s risk characteristics have changed, and we exclude the loan 
from the general allowance pool, typically designating it as nonaccruing. For these loans, a specific allowance reflects the 
expected credit loss.   

We measure specific allowances for loans excluded from the general allowance pool by an evaluation of estimated future cash 
flows discounted at the loans initial effective interest rate or the fair value of collateral for certain collateral dependent loans. 
For a non-collateral dependent loan, the specific allowance is the amount by which the loan’s amortized cost basis exceeds its 
net realizable value. We measure the specific allowance for collateral dependent loans as the amount by which the loan’s 
amortized cost basis exceeds its fair value. When repayment is expected to be provided substantially through the sale of 
collateral, we deduct estimated selling costs from the collateral’s fair value. Generally, third party appraisals that conform to 
Uniform Standards of Professional Appraisal Practice serve as the basis for the fair value of real property held as collateral. 
These appraised values are on an “as-is” basis and generally are not adjusted by the Company. We obtain updated appraisals at 
least annually or more frequently if market conditions indicate collateral values may have declined. For energy loans, our 
internal staff of engineers generally determines collateral value of mineral rights based on projected cash flows from proven oil 
and gas reserves under existing economic and operating conditions. For real property held as collateral for other loans, third 
party appraisals that conform to Uniform Standards of Professional Appraisal Practice generally serve as the basis for the fair 
value. These appraised values are on an “as-is” basis and generally are not adjusted by the Company. We obtain updated 
appraisals at least annually or more frequently if market conditions indicate collateral values may have declined. Our special 
assets staff generally determines the value of other collateral based on projected liquidation cash flows under current market 
conditions. We evaluate collateral values and available cash resources quarterly. Historical statistics may be used to estimate 
specific allowances in limited situations, such as when a collateral dependent loan is removed from the general allowance pool 
near the end of a reporting period until an appraisal of collateral value is received or a full assessment of future cash flows is 
completed.  

92

General allowances estimate expected credit losses on pools of loans sharing similar risk characteristics that are expected to 
occur over the loan’s estimated remaining life. The loan’s estimated remaining life represents the contractual term adjusted for 
amortization, estimates of prepayments, and borrower-owned extension options. Approximately 90 percent of the committed 
dollars in the loan portfolio is risk graded loans with general allowance model inputs that include probability of default, loss 
given default, and exposure at default. Probability of default is based on the migration of loans from performing to 
nonperforming using historical life of loan analysis periods. Loss given default is based on the aggregate losses incurred, net of 
estimated recoveries. Exposure at default represents an estimate of the outstanding amount of credit exposure at the time a 
default may occur.  

Charge-off migration is used to calculate the general allowance for the majority of non-risk graded loans to individuals. The 
expected credit loss on less than 10 percent of the committed dollars in the portfolio is calculated using charge-off migration. 

The expected credit loss on approximately 1 percent of the committed dollars in the portfolio is calculated using a non-modeled 
approach. Specifically, the calculation applies a long-term net charge-off rate to the loan balances, adjusted for the weighted 
average remaining maturity of each portfolio.  

In estimating the expected credit losses for general allowances on performing risk-graded loans, each portfolio class is assigned 
relevant economic loss drivers which best explain variations in portfolio net loss rates. The probability of default estimates for 
each portfolio class are adjusted for current and forecasted economic conditions. The result is applied to the exposure at default 
and loss given default to calculate the lifetime expected credit loss estimate. Selection of relevant economic loss drivers is re-
evaluated periodically and involves statistical analysis as well as management judgment. The unemployment rate factors 
significantly in the allowance for loan losses calculation, affecting commercial and loans to individuals segments. Other 
primary factors impacting the commercial portfolio include BBB corporate spreads, real gross domestic product growth rate, 
and energy commodity prices. The primary commercial real estate variables are vacancy rate and BBB corporate spreads. In 
addition to the unemployment rate, the forecast for loans to individuals is tied to home price index. The forecasts may include 
regional economic factors when localized conditions diverge from national conditions.  

An Economic Forecast Committee, consisting of senior management with members largely independent of the allowance 
process develops a twelve-month forward-looking forecast for the relevant economic loss drivers. Management develops these 
forecasts based on external data as well as a view of future economic conditions, which may include adjustments for regional 
conditions. The forecast includes three economic scenarios and probability weights for each scenario. The base forecast 
represents management's view of the most likely outcome, while the downside forecast reflects reasonably possible worsening 
economic conditions, and the upside forecast projects reasonably possible improving conditions.  

At the end of the one-year reasonable and supportable forecast period, we transition from shorter-term expected losses to long-
term loss averages for the loan’s estimated remaining life. The difference between short-term loss forecasts and long-term loss 
averages is run-off over the reversion horizon, up to three years, depending on the forecasted economic scenarios.      

General allowances also consider the estimated impact of factors that are not captured in the modeled results or historical 
experience. These factors may increase or decrease modeled results by amounts determined by the Allowance Committee. 
Factors not captured in modeled results or historical experience may include for example, new lines of business, market 
conditions that have not been previously encountered, observed changes in credit risk that are not yet reflected in macro-
economic factors, or economic conditions that impact loss given default assumptions.    

The accrual for off-balance sheet credit risk is maintained at a level that is appropriate to cover estimated losses associated with 
credit instruments that are not currently recognized as assets such as loan commitments, standby letters of credit or guarantees 
that are not unconditionally cancellable by the bank. This accrual is included in other liabilities in the Consolidated Balance 
Sheets. The appropriateness of the accrual is determined in the same manner as the allowance for loan losses, with the added 
consideration of commitment usage over the remaining life for those loans that the bank can not unconditionally cancel.

A provision for credit losses is charged against or credited to earnings in amounts necessary to maintain an appropriate 
Allowance for Credit Losses. Recoveries of loans previously charged off are added to the allowance when received.  

93

Real Estate and Other Repossessed Assets

Real estate and other repossessed assets are acquired in partial or total forgiveness of loans. These assets are initially recognized 
at cost, which is determined by fair value at date of foreclosure less estimated disposal costs. They are subsequently carried at 
the lower of cost or current fair value less estimated disposal costs. Decreases in fair value below cost are recognized as asset-
specific valuation allowances which may be reversed when supported by future increases in fair value. Subsequent increases in 
fair value may be used to reduce the allowance but not below zero.

Fair values of real estate are based on “as is” appraisals which are updated at least annually or more frequently for certain asset 
types or assets located in certain distressed markets. Fair values based on appraisals are generally considered to be based on 
significant other observable inputs. The Company also considers decreases in listing price and other relevant information in 
quarterly evaluations and reduces the carrying value of real estate and other repossessed assets when necessary. Fair values 
based on list prices and other relevant information are generally considered to be based on significant unobservable inputs. 
Additional costs incurred to complete real estate and other repossessed assets may increase the carrying value, up to current fair 
value based on “as completed” appraisals. The fair value of mineral rights included in repossessed assets is generally 
determined by our internal staff of engineers based on projected cash flows from proven oil and gas reserves under existing 
economic and operating conditions. The value of other repossessed assets is generally determined by our special assets staff 
based on projected liquidation cash flows under current market conditions.

Income generated by these assets is recognized as received. Operating expenses are recognized as incurred. Gains or losses on 
sales of real estate and other repossessed assets are based on the cash proceeds received less the cost basis of the asset, net of 
any valuation allowances. The estimated disposal costs of real estate and other repossessed assets are evaluated by the Company 
on an annual basis based on actual results.

Transfers of Financial Assets

BOK Financial regularly transfers financial assets as part of its mortgage banking activities and periodically may transfer other 
financial assets. Transfers are recorded as sales when the criteria for surrender of control are met.  

The Company has elected to carry certain residential mortgage loans held for sale at fair value under the fair value option. 
Changes in fair value are recognized in net income as they occur. These loans are reported separately in the Consolidated 
Balance Sheets and changes in fair value are recorded in Other Operating Revenue - Mortgage banking revenue in the 
Consolidated Statements of Earnings.  

Fair value of conforming residential mortgage loans that will be sold to U.S. government agencies is based on sales 
commitments or market quotes considered Level 2 inputs. Fair value of mortgage loans that are unable to be sold to U.S. 
government agencies is based on Level 3 inputs using quoted prices of loans that are sold in securitization transactions with a 
liquidity discount applied. The fair value is corroborated with an independent third party on at least an annual basis.  

BOK Financial retains a repurchase obligation under underwriting representations and warranties related to residential 
mortgage loans transferred and generally retains the right to service the loans. These are not credit obligations. The Company 
may incur a recourse obligation in limited circumstances. Separate accruals are recognized in Other liabilities in the 
Consolidated Balance Sheets for repurchase and recourse obligations. These reserves reflect the estimated amount of probable 
loss the Company will incur as a result of repurchasing a loan, indemnifications, and other settlement resolutions.  

Repurchases of loans with an origination defect that are also credit impaired are considered collateral dependent and are 
initially recognized at net realizable value (appraised value less the cost to sell). The difference between unpaid principal 
balance and net realizable value is not accreted. Repurchases of loans with an origination defect that are not credit impaired are 
carried at fair value as of the repurchase date. Interest income continues to accrue on these loans and the discount is accreted 
over the estimated life of the loan.

The Company may also choose to purchase GNMA loans once certain mandated delinquency criteria are met. The loans that 
are eligible and are chosen to be repurchased are initially recognized at fair value based on expected cash flows discounted 
using the average agency guaranteed debenture rates, average actual principal loss rates and liquidity premium.

94

 
 
Mortgage Servicing Rights

Mortgage servicing rights may be purchased or may be recognized when mortgage loans are originated and sold with servicing 
rights retained. All mortgage servicing rights are carried at fair value. Changes in the fair value are recognized in earnings as 
they occur.

Mortgage servicing rights are not traded in active markets. A cash flow model is used to determine fair value. Key assumptions 
and estimates, including projected prepayment speeds and assumed servicing costs, earnings on escrow deposits, ancillary 
income and discount rates, used by this model are based on current market sources. Assumptions used to value mortgage 
servicing rights are considered significant unobservable inputs. A separate third-party model is used to estimate prepayment 
speeds based on interest rates, housing turnover rates, estimated loan curtailment, anticipated defaults and other relevant 
factors. The prepayment model is updated daily for changes in market conditions and adjusted to better correlate with actual 
performance of BOK Financial's servicing portfolio. Fair value estimates from outside sources are received at least annually to 
corroborate the results of the valuation model.

Premises and Equipment

Premises and equipment are carried at cost, including capitalized interest when appropriate, less accumulated depreciation and 
amortization. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the assets 
or, for leasehold improvements, over the shorter of the estimated useful lives or remaining lease terms. Useful lives range from 
5 years to 40 years for buildings and improvements, 3 years to 10 years for software and related implementation costs, and 3 
years to 10 years for furniture and equipment. Construction in progress represents facilities construction and data processing 
systems projects underway that have not yet been placed into service. Depreciation and amortization begin once the assets are 
placed into service. 

Repair and maintenance costs, including software maintenance and enhancement costs, are charged to expense as incurred. 
Software licensing costs are generally charged to expense as incurred. Software licensing costs are capitalized if the contractual 
right to take possession of the software exists and it is feasible to take possession without significant penalty. Capitalized costs 
are amortized over the shorter of the estimated useful life of the software or remaining contractual life of the license.

Premises no longer used by the Company are transferred to real estate and other repossessed assets. The transferred amount is 
the lower of cost less accumulated depreciation or fair value less estimated disposal costs as of the transfer date.

Premises and equipment includes rights to use leased facilities and equipment. Right of use assets are initially measured by the 
present value of future rent payments over lease terms, adjusted for rent concessions. Rent payments exclude both payments 
made for non-lease components such as services and variable lease payments other than payments dependent on an index at 
lease commencement. Lease term includes options reasonably certain to be exercised. The right of use assets and lease 
liabilities are amortized to achieve straight-line expense over the lease term. Upon lease modification, the right of use asset and 
liability are reassessed and remeasured. Right of use assets are evaluated for impairment when facts and circumstances change 
that indicate an impairment may be necessary. Leases less than twelve months are excluded from capitalization.

Ongoing technology projects of significant size or length are reviewed at least annually for impairment. Accumulated costs are 
reviewed for projects or components of projects that do not support the value of the asset being developed. Findings of 
obsolescence, duplicate effort or other conditions that do not support the recorded value are impaired, with the cost of the 
impaired components being charged to current-year earnings.

Federal and State Income Taxes

BOK Financial and its subsidiaries file consolidated tax returns. The subsidiaries provide for income taxes on a separate return 
basis and remit to BOK Financial amounts determined to be currently payable. BOK Financial is an agent for its subsidiaries 
under the Company's tax sharing agreements and has no ownership rights to any refunds received for the benefit of its 
subsidiaries. 

Current income tax expense or benefit is based on an evaluation that considers estimated taxable income, tax credits, and 
statutory federal and state income tax rates. The amount of current income tax expense or benefit recognized in any period may 
differ from amounts reported to taxing authorities. Annually, tax returns are filed with each jurisdiction where the Company 
conducts business and recognized current income tax expense or benefit is adjusted to the filed tax returns.

95

 
 
 
Deferred tax assets and liabilities are based upon the temporary differences between the values of assets and liabilities as 
recognized in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the 
differences are expected to be recovered or settled. The effect of changes in statutory tax rates on the measurement of deferred 
tax assets and liabilities is recognized through income tax expense in the period the change is enacted. A valuation allowance is 
provided when it is more likely than not that some portion of the entire deferred tax asset may not be realized.  

BOK Financial has unrecognized tax benefits, which are included in accrued current income taxes payable, for the uncertain 
portion of recorded tax benefits and related interest. These uncertainties result from the application of complex tax laws, rules, 
regulations and interpretations, primarily in state taxing jurisdictions. Unrecognized tax benefits are assessed quarterly and may 
be adjusted through current income tax expense in future periods based on changing facts and circumstances, completion of 
examinations by taxing authorities or expiration of a statute of limitations. Estimated penalties and interest on uncertain tax 
positions are recognized in income tax expense.

Employee Benefit Plans

BOK Financial sponsors a defined contribution plan (“Thrift Plan”) and a defined benefit cash balance pension plan (“Pension 
Plan”). Employer contributions to the Thrift Plan, which matches employee contributions subject to percentage and years of 
service limits, are expensed when incurred. Pension Plan costs, which are based upon actuarial computations of current costs, 
are expensed annually. Pension Plan benefits were curtailed as of April 1, 2006. No participants may be added to the Pension 
Plan and no additional service benefits will be accrued. BOK Financial recognizes the funded status of its employee benefit 
plans. Adjustments required to recognize the Pension Plan's net funded status are made through accumulated other 
comprehensive income, net of deferred income taxes.

Share-Based Compensation Plans

BOK Financial awards non-vested common shares and stock options as compensation to certain officers. The grant date fair 
value of non-vested shares is based on the then-current market value of BOK Financial common stock. Non-vested shares 
generally cliff vest in 3 years and are subject to a holding period after vesting of 2 years. The grant date fair value of stock 
options is based on the Black-Scholes option pricing model. Stock options generally have graded vesting over 7 years. Each 
tranche is considered a separate award for valuation and compensation cost recognition. 

Compensation cost is initially based on the grant date fair value of the award and recognized as expense over the service period, 
which is generally the vesting period. Expense is reduced for estimated forfeitures over the vesting period and adjusted for 
actual forfeitures as they occur. Share-based compensation awarded to certain officers has performance conditions that affect 
the number of awards granted. Compensation cost is adjusted based on the probable outcome of the performance conditions. 

Restricted stock units ("RSUs") may also be awarded for certain executives who have elected to defer income recognition upon 
vesting of their awards. RSUs are subject to the same vesting criteria as non-vested shares. The value of the awards will vary in 
amounts equal to changes in the fair value of an equal number of BOK Financial common shares. 

Tax effects of share-based payments are recognized through tax expense. Dividends on non-vested shares are charged to 
retained earnings. Dividend equivalents on RSUs are charged to expense. 

Other Operating Revenue

Fees and commissions revenue is generated through the sales of products, consisting primarily of financial instruments, and the 
performance of services for customers under contractual obligations. Revenue from providing services for customers is 
recognized at the time services are provided in an amount that reflects the consideration we expect to be entitled to for those 
services. Revenue is recognized based on the application of five steps:
•
•
•
•
•

Identify the contract with a customer
Identify the performance obligations in the contract
Determine the transaction price
Allocate the transaction price to the performance obligations in the contract
Recognize revenue when (or as) the Company satisfies a performance obligation

For contracts with multiple performance obligations, individual performance obligations are accounted for separately if the 
customer can benefit from the good or service on its own or with other resources readily available to the customer and the 
promise to transfer goods and services to the customer is separately identifiable in the contract. The transaction price is 
allocated to the performance obligations based on relative standalone selling prices.  

96

 
 
 
Revenue is recognized on a gross basis whenever we have primary responsibility and risk in providing the services or products 
to our customers and have discretion in establishing the price for the services or products. Revenue is recognized on a net basis 
whenever we act as an agent for products or services of others.

Brokerage and trading revenue includes revenues from trading, customer hedging, retail brokerage, investment banking and 
insurance brokerage. Trading revenue includes net realized and unrealized gains primarily related to sales of securities to 
institutional customers and related derivative contracts. Customer hedging revenue includes realized and unrealized changes in 
the fair value of derivative contracts held for customer risk management programs including credit valuation adjustments, as 
necessary. We offer commodity, interest rate, foreign exchange and equity derivatives to our customers. These customer 
contracts are offset with contracts with selected counterparties and exchanges to minimize changes in market risk from changes 
in commodity prices, interest rates or foreign exchange rates. Retail brokerage revenue represents fees and commissions earned 
on sales of fixed income securities, annuities, mutual funds and other financial instruments to retail customers. Investment 
banking revenue includes fees earned upon completion of underwriting and financial advisory services. Investment banking 
revenue also includes fees earned in conjunction with loan syndications. Insurance brokerage revenues represent fees and 
commissions earned on placement of insurance products with carriers for property and casualty and health coverage.  

Transaction card revenue includes merchant discount fees and electronic funds transfer network fees, net of interchange fees 
paid to card issuers and assessments paid to card networks. Merchant discount fees represent fees paid by customers for account 
management and electronic processing of card transactions. Merchant discount fees are recognized at the time the customer’s 
transactions are processed or other services are performed. The Company also maintains the TransFund electronic funds 
transfer network for the benefit of its members, which includes BOKF, NA. Electronic funds transfer fees are recognized as 
electronic transactions are processed on behalf of its members. 

Fiduciary and asset management revenue includes fees from asset management, custody, recordkeeping, investment advisory 
and administration services. Revenue is recognized on an accrual basis at the time the services are performed and may be based 
on either the fair value of the account or the service provided.

Deposit service charges and fees include commercial account service charges, overdraft fees, check card fee revenue and 
automated service charge and other deposit service fees. Fees are recognized at least quarterly in accordance with published 
deposit account agreements and disclosure statements for retail accounts or contractual agreements for commercial 
accounts. Item charges for overdraft or non-sufficient funds items are recognized as items are presented for payment. Account 
balance charges and activity fees are accrued monthly and collected in arrears. Commercial account activity fees may be offset 
by an earnings credit based on account balances. Check card fees represent interchange fees paid by a merchant bank for 
transactions processed from cards issued by the Company. Check card fees are recognized when transactions are processed.   

Mortgage banking revenue includes revenues recognized in conjunction with the origination, marketing and servicing of 
conventional and government-sponsored residential mortgage loans. Mortgage production revenue includes net realized gains 
(losses) on sales of residential mortgage loans in the secondary market and the net change in unrealized gains (losses) on 
residential mortgage loans held for sale. Mortgage production revenue also includes changes in the fair value of derivative 
contracts not designated as hedging instruments related to residential mortgage loan commitments and forward sales contracts. 
Mortgage servicing revenue includes servicing fee income and late charges on loans serviced for others.  

Newly Adopted and Pending Accounting Pronouncements

The following is a summary of newly adopted and pending accounting pronouncements that may have a more than insignificant 
effect on the Company's financial statements. 

Financial Accounting Standards Board ("FASB")

FASB Accounting Standards Update No. 2016-02, Leases (Topic 842) ("ASU 2016-02")

On February 25, 2016, the FASB issued ASU 2016-02 to increase transparency and comparability by recognizing lease assets 
and liabilities on the balance sheet and disclosing key information about leasing arrangements. The Company adopted the new 
standard January 1, 2019 through a cumulative effect adjustment to retained earnings. The implementation of ASU 2016-02 
increased the reported right-of-use asset and lease liability by $137 million. The effect on retained earnings was immaterial. 

97

 
 
FASB Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Assets Measured at 
Amortized Cost ("ASU 2016-13")

On June 16, 2016, the FASB issued ASU 2016-13 to provide more timely recording of credit losses on loans and other financial 
assets measured at amortized cost. The Company adopted the new standard January 1, 2020, through a cumulative effect 
adjustment to retained earnings. Prior periods were not restated. 

Under ASU 2016-13, acquired loans must be reserved in a manner consistent with originated loans while the incurred loss 
model excluded purchased loans because the loans had been marked to fair value at acquisition. Under ASU 2016-13, the fair 
value discount will remain in place and be accreted into interest income over the life of any acquired loans in the portfolio. 

Another transition adjustment component is related to expected credit losses for residential mortgage loans sold that exceed 
amounts guaranteed by the U.S. Department of Veterans Affairs as we retain the credit risk for any amounts exceeding the 
guarantee as well as for recourse loans.  

Prior to ASU 2016-13, held-to-maturity non-agency securities carried no reserve for credit losses. 

Note 4 disaggregates the transition adjustment for loans and unfunded loan commitments among portfolio segments as well as 
on-and off-balance sheet reserves.  

FASB Accounting Standards Update No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit 
Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments ("ASU 2019-04")

On April 25, 2019, the FASB issued ASU 2019-04 which clarifies certain aspects of the accounting for credit losses, hedging 
activities, and financial instruments addressed by ASUs 2016-13, 2017-12, and 2016-01, respectively. Significant amendments 
made to the provisions of ASU 2016-13 by ASU 2019-04 include providing certain alternatives for the measurement of the 
allowance for credit losses on accrued interest receivable and clarifying steps entities should take when recording the transfer of 
loans or debt securities between measurement classification or categories. ASU 2019-04 further clarifies the expectation that 
entities include recoveries of financial assets in the calculation of the current expected credit losses allowance for both pools of 
financial assets and individual financial assets. Significant amendments made to the provisions of ASU 2017-12 by ASU 
2019-04 include clarification on partial-term fair value hedges of interest rate risk, amortization of fair value hedge basis 
adjustments and disclosure of fair value hedge basis adjustments. Significant amendments made to provisions of ASU 2016-01 
include clarification of the measurement alternative practice for equity securities and remeasurement of equity securities at 
historical exchange rates. ASU 2019-04 includes other amendments which clarify various provisions within the codification. 
The Company adopted ASU 2019-04 in the first quarter of 2020. Adoption of ASU 2019-04 did not have a material impact on 
the Company's financial statements.   

FASB Accounting Standards Update No. 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition 
Relief ("ASU 2019-05")

On May 15, 2019, the FASB issued ASU 2019-05 which provides transition relief for entities adopting the Board's credit losses 
standard, ASU 2016-13. ASU 2019-05 amends ASU 2016-13 to allow companies to irrevocably elect, upon adoption of ASU 
2016-13, the fair value option for financial instruments that meet specific requirements and is effective for the Company for 
annual reporting periods beginning after December 15, 2019. The Company did not elect the fair value option for additional 
financial instruments.

FASB Accounting Standards Update No. 2019-11, Codification Improvements to Topic 326: Financial Instruments-Credit 
Losses ("ASU 2019-11")

On November 27, 2019, the FASB issued ASU 2019-11 which revises certain aspects of new guidance on credit losses. Topics 
addressed include purchased credit-deteriorated assets, transition relief for troubled debt restructurings, disclosure relief for 
accrued interest receivable, and financial assets secured by collateral maintenance provisions. ASU 2019-11 is effective for the 
Company for annual reporting periods beginning after December 15, 2019. The Company adopted ASU 2019-11 in the first 
quarter of 2020. Adoption of ASU 2019-11 did not have a material impact on the Company's financial statements.

FASB Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes 
("ASU 2019-12")

On December 18, 2019, the FASB issued ASU 2019-12 which simplifies the accounting for income taxes by eliminating certain 
exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim 
period and the recognition of deferred tax liabilities for outside basis differences. The ASU also simplifies aspects of accounting 
for franchise taxes and enacted changes in tax laws or rates and clarifies accounting for transactions that result in a step-up in 
the tax basis of goodwill. ASU 2019-12 is effective for the Company for annual reporting periods beginning after December 15, 
2020, and interim periods within; however, early adoption is permitted. The Company adopted ASU 2019-12 in the first quarter 
of 2020. Adoption of ASU 2019-12 did not have a material impact on the Company's financial statements.  

FASB Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference 
Rate Reform on Financial Reporting ("ASU 2020-04")

On March 12, 2020, the FASB issued ASU 2020-04 which provides optional expedients and exceptions for applying U.S. 
GAAP to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be 
discontinued, subject to meeting certain criteria. Under the new guidance, an entity can elect by accounting topic or industry 
subtopic to account for the modification of a contract affected by reference rate reform as a continuation of the existing 
contract, if certain conditions are met. In addition, the new guidance allows an entity to elect on a hedge-by-hedge basis to 
continue to apply hedge accounting for hedging relationships in which the critical terms change due to reference rate reform, if 
certain conditions are met. A one-time election to sell and/or transfer held-to-maturity debt securities that reference a rate 
affected by reference rate reform is also allowed. ASU 2020-04 became effective for all entities as of March 12, 2020 and will 
apply to all LIBOR reference rate modifications through December 31, 2022. Management is currently evaluating the impact of 
ASU 2020-04 on the Company's financial statements.

FASB Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848): Scope ("ASU 2021-01")

On January 7, 2021, the FASB issued ASU 2021-01 which clarifies that certain optional expedients and exceptions in Topic 
848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The 
amendments in this update are elective and apply to all entities that have derivative instruments that use an interest rate for 
margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments also 
optionally apply to all entities that designate receive-variable rate, pay-variable-rate cross-currency interest rate swaps as 
hedging instruments in net investment hedges that are modified as a result of reference rate reform. ASU 2021-01 is effective 
immediately for all entities and amendments may be applied on a full retrospective basis as of any date from the beginning of 
an interim period that includes or is subsequent to March 12, 2020. Management is currently evaluating the impact of ASU 
2021-01 on the Company's financial statements.

No credit impairment of available for sale securities was recognized in 2020. Unrealized losses related to changes in interest rates 
subsequent to purchase and are not attributable to credit. Based on evaluations of impaired securities as of December 31, 2020, the 
Company does not intend to sell any impaired available for sale securities before fair value recovers to the current amortized cost and 
it is more-likely-than-not that the Company will not be required to sell impaired securities before fair value recovers, which may be 
maturity.

Fair Value Option Securities

Fair value option securities represent securities which the Company has elected to carry at fair value and are separately identified on 
the Consolidated Balance Sheets with changes in the fair value recognized in earnings as they occur. Certain residential mortgage-
backed securities issued by U.S. government agencies and derivative contracts are held as an economic hedge of the mortgage 
servicing rights.

At December 31, 2020, loans to businesses and individuals with collateral primarily located in Texas totaled $7.2 billion or 
31% of the total loan portfolio. Loans to businesses and individuals with collateral primarily located in Oklahoma totaled $3.8 
billion or 17% of our total loan portfolio. Loans to businesses and individuals with collateral primarily located in Colorado 
totaled $2.8 billion or 12% of our total loan portfolio. Loans for which the collateral location is not relevant, such as unsecured 
loans and reserve-based energy loans, are distributed by the borrower’s primary operating location. These geographic 
concentrations subject the loan portfolio to the general economic conditions within these areas. 

At December 31, 2019, loans to businesses and individuals with collateral primarily located in Texas totaled $6.8 billion or 
31% of the loan portfolio, loans to businesses and individuals with collateral primarily located in Oklahoma totaled $3.5 billion 
or 16% of the loan portfolio and loans to businesses and individuals with collateral primarily located in Colorado totaled $2.8 
billion or 13% of the loan portfolio.

Commercial

Commercial loans represent loans for working capital, facilities acquisition or expansion, purchases of equipment and other 
needs of commercial customers primarily located within our geographical footprint. Commercial loans are underwritten 
individually and represent on-going relationships based on a thorough knowledge of the customer, the customer’s industry and 
market. While commercial loans are generally secured by the customer’s assets including real property, inventory, accounts 
receivable, operating equipment, interest in mineral rights and other property and may also include personal guarantees of the 
owners and related parties, the primary source of repayment of the loans is the on-going cash flow from operations of the 
customer’s business. Inherent lending risk is centrally monitored on a continuous basis from underwriting throughout the life of 
the loan for compliance with commercial lending policies.

At December 31, 2020, commercial loans with collateral primarily located in Texas totaled $4.3 billion or 33% of the 
commercial loan portfolio segment. Commercial loans with collateral primarily located in Oklahoma totaled $1.8 billion or 
14% of the commercial loan portfolio segment. Commercial loans with collateral primarily located in Colorado totaled $1.7 
billion or 13% of the commercial loan portfolio segment. The commercial loan portfolio segment is further divided into loan 
classes. The services loan class totaled $3.5 billion or 15% of total loans. Approximately $1.8 billion of loans in the services 
class consisted of loans with individual balances of less than $10 million. Businesses included in the services class include 
Native American tribal and state and local municipal government entities, Native American tribal casino operations, educational 
services, foundations and not-for-profit organizations and specialty trade contractors. The energy loan class totaled $3.5 billion 
or 15% of total loans, including $2.6 billion of outstanding loans to energy producers. Approximately 67% of the committed 
production loans are secured by properties primarily producing oil and 33% of the committed production loans are secured by 
properties primarily producing natural gas. The healthcare loan class totaled $3.3 billion or 14% of total loans. The healthcare 
loan class consists primarily of loans for the development and operation of senior housing and care facilities, including 
independent living, assisted living and skilled nursing. Healthcare also includes loans to hospitals and other medical service 
providers.

At December 31, 2019, commercial loans with collateral primarily located in Texas totaled $4.7 billion or 33% of the 
commercial loan portfolio segment, commercial loans with collateral primarily located in Oklahoma totaled $2.0 billion or 14% 
of the commercial loan portfolio segment and commercial loans with collateral primarily located in Colorado totaled $2.0 
billion or 14% of the commercial loan portfolio segment. The energy loan class totaled $4.0 billion or 18% of total loans, 
including $3.1 billion of outstanding loans to energy producers. At December 31, 2019, approximately 58% of committed 
production loans were secured by properties primarily producing oil and 42% were secured by properties producing natural gas. 
The services loan class totaled $3.8 billion or 18% of total loans. Approximately $1.5 billion of loans in the services category 
consisted of loans with individual balances of less than $10 million. The healthcare loan class totaled $3.0 billion or 14% of 
total loans.

Commercial Real Estate

Commercial real estate loans are for the construction of buildings or other improvements to real estate and property held by 
borrowers for investment purposes primarily within our geographical footprint. We require collateral values in excess of the 
loan amounts, demonstrated cash flows in excess of expected debt service requirements, equity investment in the project and a 
portion of the project already sold, leased or permanent financing already secured. The expected cash flows from all significant 
new or renewed income producing property commitments are stress tested to reflect the risks in varying interest rates, vacancy 
rates and rental rates. As with commercial loans, inherent lending risks are centrally monitored on a continuous basis from 
underwriting throughout the life of the loan for compliance with applicable lending policies.

108

At December 31, 2020, 27% of commercial real estate loans were secured by properties primarily located in the Dallas and 
Houston metropolitan areas of Texas and 10% of commercial real estate loans were secured by properties located primarily in 
the Tulsa and Oklahoma City metropolitan areas of Oklahoma. At December 31, 2019, 24% of commercial real estate loans are 
secured by properties primarily located in the Dallas and Houston metropolitan areas of Texas, 12% of commercial real estate 
loans were secured by properties located primarily in the Tulsa and Oklahoma City metropolitan areas of Oklahoma and 11% of 
commercial real estate loans are secured by properties located primarily in the Denver, Colorado metropolitan area.

Paycheck Protection Program

BOK Financial is actively participating in programs initiated by the Coronavirus Aid, Relief and Economic Security Act 
("CARES Act"), including the Small Business Administration's ("SBA") Paycheck Protection Program ("PPP") that began on 
April 3, 2020. PPP provided fully forgivable loans when utilized for qualified expenditures, including to help small business 
maintain payrolls during the COVID-19 pandemic. These loans generally have a contractual term of two years, though most are 
expected to be forgiven prior to maturity after completion of a compliance period. Loans are guaranteed and amounts forgiven 
will be reimbursed to the Company by the SBA. The loans carry a rate of 1 percent. Interest plus loan fees, which vary 
depending on loan size, are accrued over the contractual life of the loan. Any unaccreted origination fees will be recognized 
when the loan is paid. 

Loans to Individuals

Loans to individuals include residential mortgage and personal loans. Residential mortgage loans provide funds for our 
customers to purchase or refinance their primary residence or to borrow against the equity in their home. These loans are 
secured by a first or second mortgage on the customer's primary residence. These loans are made in accordance with 
underwriting policies we believe to be conservative and are fully documented. Loans may be individually underwritten or credit 
scored based on size and other criteria. Credit scoring is assessed based on significant credit characteristics including credit 
history, residential and employment stability. 

In general, we sell the majority of our conforming fixed rate loan originations in the secondary market and retain the majority of 
our non-conforming and adjustable-rate mortgage loans. Our mortgage loan portfolio does not include payment option 
adjustable rate mortgage loans or adjustable rate mortgage loans with initial rates that are below market. Home equity loans are 
primarily first-lien and fully amortizing. 

Residential mortgage, which includes home equity loans, and personal loans are made in accordance with underwriting policies 
we believe to be conservative and are fully documented. Loans may be individually underwritten or credit scored based on size 
and other criteria. Credit scoring is assessed based on significant credit characteristics including credit history, residential and 
employment stability. 

Personal loans consist primarily of loans to Wealth Management clients secured by the cash surrender value of insurance 
policies and marketable securities. It also includes direct loans secured by and for the purchase of automobiles, recreational and 
marine equipment as well as unsecured loans.

Approximately 91% of the loans in this segment are secured by collateral located within our geographical footprint. Loans for 
which the collateral location is less relevant, such as unsecured loans are categorized by the borrower’s primary operating 
location. 

Residential mortgage loans guaranteed by U.S. government agencies have limited credit exposure because of the agency 
guarantee. This amount includes residential mortgage loans previously sold into GNMA mortgage pools that the Company may 
repurchase when certain defined delinquency criteria are met. Because of this repurchase right, the Company is deemed to have 
regained effective control over these loans and must include them on the Consolidated Balance Sheet.

Credit Commitments

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of conditions established in 
the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. 
At December 31, 2020, outstanding commitments totaled $11.0 billion. Because some commitments are expected to expire 
before being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. BOK Financial 
uses the same credit policies in making commitments as it does loans.

The amount of collateral obtained, if deemed necessary, is based upon management’s credit evaluation of the borrower.

109

 
Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. 
Because the credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan 
commitments, BOK Financial uses the same credit policies in evaluating the creditworthiness of the customer. Additionally, 
BOK Financial uses the same evaluation process in obtaining collateral on standby letters of credit as it does for loan 
commitments. The term of these standby letters of credit is defined in each commitment and typically corresponds with the 
underlying loan commitment. At December 31, 2020, outstanding standby letters of credit totaled $681 million. 

Allowances for Credit Losses and Accrual for Off-balance Sheet Credit Risk from Unfunded Loans Commitments

BOK Financial maintains an allowance for loan losses and accrual for off-balance sheet credit risk from unfunded 
commitments. The allowance consists of specific allowances attributed to certain individual loans, generally nonaccruing loans, 
with dissimilar risk characteristics that have not yet been charged down to amounts we expect to recover and general 
allowances for estimated credit losses on pools of loans that share similar risk characteristics based on probability of default, 
loss given default and exposure at default for each loan class developed based on current and forecasted relevant economic loss 
drivers.

The accrual for off-balance sheet credit risk is maintained at a level that is appropriate to cover estimated losses associated with 
credit instruments that are not currently recognized as assets such as loan commitments, standby letters of credit or guarantees 
that are not unconditionally cancellable by the bank. 

The activity in the allowance for loan losses and the allowance for off-balance sheet credit losses related to loan commitments 
and standby letters of credit is for the year ended December 31, 2020 summarized as follows (in thousands):

Changes in our reasonable and supportable forecasts of macroeconomic variables, primarily due to the anticipated impact of the 
on-going COVID-19 pandemic, and other assumptions, resulted in a $99.1 million increase in the allowance for lending 
activities during the year ended December 31, 2020. Changes in the loan portfolio characteristics, including specific impairment 
and losses, loan balances and risk grading resulted in a $135.2 million increase in the allowance for lending activities.

The Company utilizes risk grading as primary credit quality indicators as it influences the probability of default which is a key 
attribute in the expected credit losses calculation. Substantially all commercial as well as commercial real estate loans and 
certain loans to individuals are risk graded based on a quarterly evaluation of the borrowers’ ability to repay the loans. Certain 
commercial loans and most loans to individuals are small, homogeneous pools that are not risk-graded. The credit quality of 
these loans is based on past due days in accordance with regulatory guidelines.   

We have included in the credit quality indicator “pass” loans that are in compliance with the original terms of the agreement 
and currently exhibit no factors that cause management to have doubts about the borrowers’ ability to remain in compliance 
with the original terms of the agreement, which is consistent with the regulatory guideline of “pass.” This also includes past due 
residential mortgages that are guaranteed by agencies of the U.S. government that continue to accrue interest based on criteria 
of the guarantors’ programs. 

Other loans especially mentioned ("Special Mention") are currently performing in compliance with the original terms of the 
agreement but may have a potential weakness that deserves management’s close attention, consistent with regulatory 
guidelines. Non-graded loans 30 to 59 days past due are categorized as Special Mention.  

The risk grading process identified certain loans that have a well-defined weakness (for example, inadequate debt service 
coverage or liquidity or marginal capitalization; repayment may depend on collateral or other risk mitigation) that may 
jeopardize liquidation of the debt and represent a greater risk due to deterioration in the financial condition of the borrower. 
This is consistent with the regulatory guideline for “substandard.” Because the borrowers are still performing in accordance 
with the original terms of the loan agreements, these loans remain on accruing status. Non-graded loans 60 to 89 days past due 
are categorized as Accruing Substandard.    

Nonaccruing loans represent loans for which full collection of principal and interest is uncertain. This includes certain loans 
considered “substandard” and all loans considered “doubtful” by regulatory guidelines. Non-graded loans 90 or more days past 
due are categorized as Nonaccrual.

Probability of default is lowest for pass graded loans and increases for each credit quality indicator, Special Mention, and 
Accruing Substandard.   

Vintage represents the year of origination, except for revolving loans which are considered in aggregate. Loans that were once 
revolving but have converted to term loans without additional underwriting appear in a separate vintage column.

Impaired Loans

Loans are considered to be impaired when it is probable that the Company will not be able to collect all amounts due according 
to the contractual terms of the loan agreement. This generally includes all nonaccruing loans, all loans modified in a TDR and 
all loans repurchased from GNMA pools.

Generally, no interest income is recognized on impaired loans until all principal balances, including amounts charged-off, are 
recovered.

A summary of impaired loans at December 31, 2019 follows (in thousand):

Funds Management and Other in 2018 then allocated during 2019. 

At October 1, 2020, the Company performed a qualitative impairment assessment of goodwill based on factors including, but 
not limited to, general economic conditions, financial services industry considerations, regional economic conditions, global 
health concerns and related medical developments, general BOKF Financial performance and reporting unit performance. 
During 2020, the U.S. and global economies were negatively impacted by the spread of COVID-19. This resulted in the need 
for quarterly qualitative impairment analyses and quantitative corroboration of the annual qualitative impairment assessment. 
No impairment was indicated for any reporting unit.

(7) Mortgage Banking Activities

Residential Mortgage Loan Production

The Company originates, markets and services conventional and government-sponsored residential mortgage loans. Generally, 
conforming fixed rate residential mortgage loans are held for sale in the secondary market and non-conforming and adjustable-
rate residential mortgage loans are held for investment. The volume of mortgage loans originated for sale and secondary market 
prices are the primary drivers of originating and marketing revenue.

Residential mortgage loan commitments are generally outstanding for 60 to 90 days, which represents the typical period from 
commitment to originate a residential mortgage loan to when the closed loan is sold to an investor. Residential mortgage loan 
commitments are subject to both credit and interest rate risk. Credit risk is managed through underwriting policies and 
procedures, including collateral requirements, which are generally accepted by the secondary loan markets. Exposure to interest 
rate fluctuations is partially managed through forward sales of residential mortgage-backed securities and forward sales 
contracts. These latter contracts set the price for loans that will be delivered in the next 60 to 90 days.

The unpaid principal balance of residential mortgage loans held for sale, notional amounts of derivative contracts related to 
residential mortgage loan commitments and forward contract sales and their related fair values included in Mortgage loans held 
for sale on the Consolidated Balance Sheets were (in thousands):

Residential Mortgage Servicing

The Company generally retains the right to service residential mortgage loans sold and may purchase mortgage servicing 
rights. The unpaid principal balance of loans serviced for others is the primary driver of servicing revenue.

Changes in the fair value of mortgage servicing rights due to market changes are included in Other operating revenue in the 
Consolidated Statements of Earnings. Changes in fair value due to loan runoff are included in Mortgage banking costs. 

Mortgage servicing rights are not traded in active markets. Fair value is determined by discounting the projected net cash flows. 
Significant assumptions used to determine fair value considered to be significant unobservable inputs were as follows:

Discount rate – risk-free rate plus a market premium

Changes in primary residential mortgage interest rates directly affect the prepayment speeds used in valuing our mortgage 
servicing rights. A separate third party model is used to estimate prepayment speeds based on interest rates, housing turnover 
rates, estimated loan curtailment, anticipated defaults and other relevant factors. The prepayment model is updated periodically 
for changes in market conditions and adjusted to better correlate with actual performance of BOK Financial’s servicing 
portfolio.

1 BOK Financial maintains control over the securities underlying overnight repurchase agreements and generally transfers control over securities underlying 

longer-term dealer repurchase agreements to the respective counterparty.

Borrowings from the Federal Home Loan Banks are used for funding purposes. In accordance with policies of the Federal 
Home Loan Banks, BOK Financial has granted a blanket pledge of eligible assets (generally unencumbered U.S. Treasury and 
residential mortgage-backed securities, 1-4 family loans and multifamily loans) as collateral for these advances. The Federal 
Home Loan Banks have issued letters of credit totaling $381 million to secure BOK Financial’s obligations to depositors of 
public funds. The unused credit available to BOK Financial at December 31, 2020 pursuant to the Federal Home Loan Bank’s 
collateral policies is $8.6 billion.

In 2016, BOK Financial issued $150 million of subordinated debt that will mature on June 30, 2056. Interest on this debt bears 
an interest rate of 5.375%, payable quarterly. On June 30, 2021, BOK Financial will have the option to redeem the debt at the 
principal amount plus accrued interest, subject to regulatory approval. 

As a result of the acquisition of CoBiz Financial, we obtained $60 million of subordinated debt issued in June 2015 that will 
mature on June 25, 2030. This debt bears interest at the rate of 5.625% through June 2025 and thereafter, the notes will bear 
interest at an annual floating rate equal to three-month LIBOR plus 3.17%. The debt contains a call option that allows for 
repayment prior to contractual maturity. The call option is available on June 25, 2025 and quarterly thereafter at 100% of the 
principal amount.  

127

 
 
 
 
 
 
 
 
 
 
 
Also through CoBiz Financial, we acquired junior subordinated debentures split across three issuance tranches. Junior 
subordinated debentures of $21 million will mature September 17, 2033 and bear an interest rate of three-month LIBOR plus 
2.95% that resets quarterly. Junior subordinated debentures of $31 million will mature on July 23, 2034 and bear an interest rate 
of three-month LIBOR plus 2.60% that resets quarterly. Junior subordinated debentures of $20 million will mature on 
September 30, 2035 and bear an interest rate of three-month LIBOR plus 1.45% that resets quarterly. The junior subordinated 
debentures are subject to early redemption prior to maturity. 

BOK Financial Securities, Inc. may borrow funds from Pershing, LLC ("Pershing"), a clearing broker/dealer and a wholly 
owned subsidiary of Bank of New York Mellon, for the purposes of financing securities purchases or to facilitate funding of 
investment banking activities, on terms to be negotiated at the time of the borrowing. BOK Financial Securities, Inc. had no 
borrowings outstanding at December 31, 2020 and December 31, 2019.

The Company has a liability related to the repurchase of certain delinquent residential mortgage loans previously sold into 
GNMA mortgage pools. Interest is payable at rates contractually due to investors.

BOK Financial recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. The 
Company recognized $2.4 million for 2020, $2.2 million for 2019 and $1.7 million for 2018 in interest and penalties. The 
Company had approximately $5.9 million and $5.6 million accrued for the payment of interest and penalties at December 31, 
2020 and 2019, respectively. Federal statutes remain open for federal tax returns filed in the previous three reporting periods. 
Various state income tax statutes remain open for the previous three to six reporting periods.

(11) Employee Benefits

BOK Financial sponsors a defined benefit cash balance Pension Plan for all employees who satisfy certain age and service 
requirements. Pension Plan benefits were curtailed as of April 1, 2006. No participants may be added to the plan and no 
additional service benefits will be accrued. Interest continues to accrue on employees' account balances at a variable rate tied to 
the five-year trailing average of five-year U.S. Treasury securities plus 1.5%. The rate has a floor of 3.0% and a ceiling of 
5.0%. The 2020 quarterly variable rates ranged from 3.28% to 3.40%.

The projected benefit obligation and fair value of plan assets, respectively, were $24 million and $38 million at December 31, 
2020 and $25 million and $36 million at December 31, 2019. The net periodic benefit credit was $1.3 million for December 31, 
2020, $815 thousand for December 31, 2019 and $583 thousand for December 31, 2018. Total expected future benefit 
payments related to the Pension Plan were $26.6 million at December 31, 2020.

The following table presents the weighted-average assumptions used in the measurement of the Company's net periodic benefit 
cost as of December 31:

Discount rate

Expected return on plan assets

2020

Assets of the Pension Plan consist primarily of shares in the Cavanal Hill Active Core Fund. The stated objective of this fund is 
to provide an attractive total return with a well-balanced mix of equities and bonds. The typical portfolio mix is approximately 
60% equities and 40% bonds. The net asset value of shares in the Cavanal Hill Funds is reported daily based on market 
quotations for the Fund’s securities. Management considers the Fund's recent and long-term performance as indicators when 
setting the expected return on plan assets. No minimum contribution was required for 2020, 2019 or 2018. 

Employee contributions to the Thrift Plan are eligible for Company matching equal to 6% of base compensation, as defined in 
the plan. The Company-provided matching contribution rates range from 50% for employees with less than 4 years of service to 
200% for employees with 15 or more years of service. Additionally, a maximum Company-provided, non-elective annual 
contribution of up to $750 per participant is provided for employees whose annual base compensation is less than $40,000. 
Participants may direct investments in their accounts to a variety of options, including a BOK Financial common stock fund and 
Cavanal Hill funds. Employer contributions, which are invested in accordance with the participant’s investment options, vest 
over five years. Thrift Plan expenses were $29.9 million for 2020, $27.6 million for 2019 and $25.1 million for 2018.

(12) Share-Based Compensation Plans

The shareholders and Board of Directors of BOK Financial have approved various share-based compensation plans. An 
independent compensation committee of the Board of Directors determines the number of awards granted to the Chief 
Executive Officer and other senior executives. Share-based compensation is granted to other officers and employees as 
determined by the Chief Executive Officer.

The following table presents stock options outstanding under these plans (in thousands, except for per share data):

outstanding was 1.03 years and the weighted average remaining contractual life of vested options was 1.03 years. The aggregate 
intrinsic value of options exercised was $318 thousand for 2020, $761 thousand for 2019 and $2.3 million for 2018.

The Company also awards restricted stock to certain officers and employees and restricted stock units ("RSUs) to certain 
executives, (collectively "non-vested shares"). Vesting of all non-vested shares is subject to service requirements. Additionally, 
vesting of certain non-vested shares is subject to performance criteria based on changes in the Company's earnings per share 
relative to defined peers. The following represents a summary of the non-vested shares for the three years ended December 31,

transactions with related parties in the ordinary course of business in compliance with applicable regulations.

QuikTrip Corporation has entered into a fee sharing agreement with TransFund, BOKF’s electronic funds transfer network 
(“TransFund”), respecting transactions completed at TransFund automated teller machines placed in QuikTrip locations. In 
2020, BOKF paid QuikTrip approximately $10.0 million pursuant to this agreement. A BOK Financial director is Chief 
Executive Officer, Chairman, and a significant shareholder of QuikTrip Corporation.

Cavanal Hill Investment Management, Inc., a wholly-owned subsidiary of BOKF, NA, is the administrator to and investment

(14) Commitments and Contingent Liabilities 

Litigation Contingencies

As a member of Visa, BOK Financial is obligated for a proportionate share of certain covered litigation losses incurred by Visa 
under a retrospective responsibility plan. A contingent liability was recognized for the Company’s share of Visa’s covered 
litigation liabilities. Visa funded an escrow account to cover litigation claims, including covered litigation losses under the 
retrospective responsibility plan, with proceeds from its initial public offering in 2008 and from available cash.   

BOK Financial currently owns 252,233 Visa Class B shares which are convertible into 409,324 shares of Visa Class A shares 
after the final settlement of all covered litigation. Class B shares may be diluted in the future if the escrow fund is not adequate 
to cover future covered litigation costs. No value has been currently assigned to the Class B shares. 

On June 24, 2015, BOKF, NA received a complaint alleging that an employee had colluded with a bond issuer and an 
individual in misusing revenues pledged to municipal bonds for which BOKF, NA served as trustee under the bond indenture. 
The Company conducted an investigation and concluded that employees in one of its Corporate Trust offices had, with respect 
to a single group of affiliated bond issuances, violated Company policies and procedures by waiving financial covenants, 
granting forbearances and accepting without disclosure to the bondholders, debt service payments from sources other than 
pledged revenues. The relationship manager was terminated. The Company reported the circumstances to, and cooperated with 
an investigation by, the Securities and Exchange Commission ("SEC"). On September 7, 2016, BOKF, NA agreed, and the SEC 
entered, a consent order finding that BOKF, NA had violated Section 17(a) of the Securities Act of 1933 and Section 10(b) of 
the Securities Exchange Act and requiring BOKF, NA to disgorge $1,067,721 of fees and pay a civil penalty of $600,000. 
BOKF, NA disgorged the fees and paid the penalty.  

On December 28, 2015, in an action brought by the SEC, the United States District Court for the District of New Jersey entered 
a judgment against the principals involved in issuing the bonds, precluding the principals from denying the alleged violations of 
the federal securities laws and requiring the principals to pay all outstanding principal, accrued interest, and other amounts 
required under the bond documents, less the value of the facilities securing repayment of the bonds, subject to oversight by a 
court appointed monitor (“Payment Plan”).

On August 26, 2016, BOKF, NA was sued in the United States District Court for New Jersey by two bondholders in a putative 
class action on behalf of all holders of the bonds alleging BOKF, NA participated in the fraudulent sale of securities by the 
principals. The New Jersey Federal District Action remains stayed with no current deadlines pending. On September 14, 2016, 
BOKF, NA was sued in the District Court of Tulsa County, Oklahoma by 19 bondholders alleging BOKF, NA participated in 
the fraudulent sale of securities by the principals. The Tulsa County District Court Action is pending on BOKF, NA’s motion to 
dismiss the plaintiff's Third Amended Petition. 

On January 8, 2020, the New Jersey District Court entered judgment against the principal individual and his wife for 
$36,805,051 in principal amount and $10,937,831 in pre-judgment interest. On January 17, 2020, the New Jersey Federal 
District Court formally terminated the Payment Plan. Management is no longer able to conclude that the individual principal 
and his wife will be successful in paying the obligations they have to pay the bonds in full but such obligations remain and are 
not dischargeable in bankruptcy. Beginning September 2020, the SEC filed multiple garnishments on entities either related to or 
holding assets for the debtor. If the individual principal and his wife do not have the financial ability to pay the bonds in full, a 
bondholder loss could become probable. Management has been advised by counsel that BOKF, NA has valid defenses to claims 
of bondholders and that no loss to the company is probable. No provision for losses has been made at this time. BOKF, NA 
estimates that, upon sale of all remaining collateral securing payment of the bonds, approximately $20 million will remain 
outstanding. A reasonable estimate cannot be made of the amount of any bondholder loss, though the amount of bondholder 
loss could be material to the company in the event a loss to the company becomes probable.

On March 5, 2018, BOKF, NA was sued in the Fulton, Georgia County District Court by a Wrongful Death Judgment Creditor 
of one of the operators of a nursing home financed by one of the bonds which are the subject of the litigation discussed above. 
The judgment is alleged to total approximately $8 million in principal and interest at this time. Plaintiff alleges that BOKF, as 
Trustee, colluded with the borrower and others to defraud creditors of the nursing home by misleading the public about the 
solvency of the nursing home. Plaintiff alleges that this conduct has prevented her from collecting on her judgment. On April 
19, 2019, the Court granted BOKF, NA's Motion to Dismiss. On May 3, 2019, the plaintiff filed a Motion for Reconsideration 
which remains pending. BOKF, NA is advised by counsel that BOKF, NA has valid defenses to the plaintiffs’ claims and no 
loss is probable.

134

On March 14, 2017, BOKF, NA was sued in the United States District Court for the Northern District of Oklahoma by 
bondholders in a second putative class action representing a different set of municipal securities. The bondholders in this 
second action alleged two individuals purchased facilities from the principals who are the subject of the SEC New Jersey 
proceedings by means of the fraudulent sale of $60 million of municipal securities for which BOKF, NA also served as 
indenture trustee. On December 18, 2020, the action was dismissed with prejudice in exchange for a nominal payment.

On March 7, 2017, a plaintiff filed a putative class action in the United States District Court for the Northern District of Texas 
alleging an extended overdraft fee charged by BOKF, NA is interest and exceeds permitted rates. On September 18, 2018, the 
District Court dismissed the Texas action and the plaintiff appealed the dismissal to the United States Court of Appeals for the 
Fifth Circuit which heard argument on October 8, 2019. On August 22, 2018, a plaintiff filed a second putative class action in 
the United States District Court for New Mexico making the same allegations as the Texas action. The District Court dismissed 
the plaintiff's action. The plaintiff has appealed to the United States Court of Appeals for the Tenth Circuit. Management is 
advised by counsel that a loss is not probable in either the now dismissed Texas action or the New Mexico action and that the 
loss, if any, cannot be reasonably estimated.

On March 7, 2020, three former employees sued BOKF, NA, the Plan Committee of the BOKF, NA 401k Plan, and Cavanal 
Hill Investment Management, Inc., a subsidiary of BOKF, NA, alleging that the Defendants included proprietary investment 
products as investment options in the BOKF, NA 401k Plan, whose fees were too high and performance too low, for the 
purpose of earning fees. The action is brought as a putative class action on behalf of all Plan Participants. The action is pending 
on the defendants' motion to dismiss. Management is advised by counsel that a loss is not probable and that the loss, if any, 
cannot be reasonably estimated.  

On May 12, 2020, an accounting firm filed a putative class action in the District Court of Colorado alleging that BOKF, NA 
and other national banks failed to pay the agents of borrowers making application through the Bank to the Small Business 
Administration for Paycheck Protection Program (CARES Act) loans. The action has now been dismissed with prejudice by the 
plaintiff.

In the ordinary course of business, BOK Financial and its subsidiaries are subject to legal actions and complaints. Management 
believes, based upon the opinion of counsel, that the actions and liability or loss, if any, resulting from the final outcomes of the 
proceedings, will not have a material effect on the Company’s financial condition, results of operations or cash flows.

Alternative Investment Commitments

The Company sponsors a private equity fund and invests in several tax credit entities and other funds as permitted by banking 
regulations. Consolidation of these investments is based on the variable interest model. 

At December 31, 2020, the Company has $290 million in interests in various alternative investments generally consisting of 
unconsolidated limited partnership interests in entities for which investment return is in the form of low income housing tax 
credits or other investments in merchant banking activities. The investment balance also includes $94 million in unfunded 
commitments included in Other liabilities on the Consolidated Balance Sheets. At December 31, 2019, the Company had $259 
million in interests in various alternative investments and included $82 million in unfunded commitments in Other liabilities.

Other Commitments and Contingencies

Cavanal Hill Funds’ assets include U.S. Treasury and government securities money market funds. Assets of these funds consist 
of highly-rated, short-term obligations of the U.S. Treasury and Agencies. The net asset value of units in these funds was $1.00 
at December 31, 2020. An investment in these funds is not insured by the Federal Deposit Insurance Corporation or guaranteed 
by BOK Financial or any of its subsidiaries. BOK Financial may, but is not obligated to purchase assets from these funds to 
maintain the net asset value at $1.00. No assets were purchased from the funds in 2020 or 2019.

The Federal Reserve Bank requires member banks to maintain certain minimum average cash balances. Member banks may 
satisfy reserve balance requirements through holdings of vault cash and balances maintained directly with a Federal Reserve 
Bank. The combined average balance of vault cash and balances held at the Federal Reserve Bank was $727 million for the year 
ended December 31, 2020 and $618 million for the year ended December 31, 2019.

 (15) Shareholders Equity 

Preferred Stock

One billion shares of preferred stock with a par value of $0.00005 per share are authorized. The Series A Preferred Stock has no 
voting rights except as otherwise provided by Oklahoma corporate law and may be converted into one share of Common Stock 
for each 36 shares of Series A Preferred Stock at the option of the holder. Dividends are cumulative at an annual rate of ten 
percent of the $0.06 per share liquidation preference value when declared and are payable in cash. Aggregate liquidation 
preference is $15 million. No Series A Preferred Stock was outstanding in 2020, 2019 or 2018.

Common Stock

Common stock consists of 2.5 billion authorized shares with a $0.00006 par value. Holders of common shares are entitled to 
one vote per share at the election of the Board of Directors and on any question arising at any shareholders’ meeting and to 
receive dividends when and as declared. Additionally, regulations restrict the ability of national banks and bank holding 
companies to pay dividends.

Subsidiary Bank

The amounts of dividends that BOK Financial’s subsidiary bank can declare and the amounts of loans the subsidiary bank can 
extend to affiliates are limited by various federal banking regulations and state corporate law. Generally, dividends declared 
during a calendar year are limited to net profits, as defined, for the year plus retained profits for the preceding two years. 
Dividends are further restricted by minimum capital requirements. 

Regulatory Capital

BOK Financial and the subsidiary bank is subject to various capital requirements administered by the federal banking agencies. 
Failure to meet minimum capital requirements can initiate certain mandatory and additional discretionary actions by regulators 
that could have a material effect on BOK Financial's operations. These capital requirements include quantitative measures of 
assets, liabilities and certain off-balance sheet items. The capital standards are also subject to qualitative judgments by the 
regulators.

A bank falling below the minimum capital requirements, including the capital conservation buffer, would be subject to 
regulatory restrictions on capital distributions (including but not limited to dividends and share repurchases) and executive 
bonus payments. For a banking institution to qualify as well capitalized, Common Equity Tier 1, Tier I, Total and Leverage 
capital ratios must be at least 6.5%, 8%, 10% and 5%, respectively. Tier I capital consists primarily of common stockholders' 
equity, excluding unrealized gains or losses on available for sale securities, less goodwill, core deposit premiums and certain 
other intangible assets. Total capital consists primarily of Tier I capital plus preferred stock, subordinated debt and allowances 
for credit losses, subject to certain limitations. The subsidiary bank exceeded the regulatory definition of well capitalized as of 
December 31, 2020 and December 31, 2019.

Accumulated Other Comprehensive Income (Loss)

AOCI includes unrealized gains and losses on available for sale ("AFS") securities and non-credit related unrealized losses on 
AFS securities for which an other-than-temporary impairment has been recorded in earnings. Unrealized losses on employee 
benefit plans will be reclassified into income as pension plan costs are recognized over the remaining service period of plan 
participants. Gains and losses in AOCI are net of deferred income taxes.

BOK Financial operates three principal lines of business: Commercial Banking, Consumer Banking and Wealth Management. 
Commercial Banking includes lending, treasury and cash management services and customer risk management products to 
small businesses, middle market and larger commercial customers. Commercial Banking also includes the TransFund EFT 
network. Consumer Banking includes retail lending and deposit services, lending and deposit services to small business 
customers served through the consumer branch network and all mortgage banking activities. Wealth Management provides 
fiduciary services, private bank services, insurance and investment advisory services in all markets. Wealth Management also 
underwrites state and municipal securities and engages in brokerage and trading activities. 

In addition to its lines of business, BOK Financial has a Funds Management unit. The primary purpose of this unit is to manage 
overall liquidity needs and interest rate risk. Each line of business borrows funds from and provides funds to the Funds 
Management unit as needed to support their operations. Operating results for Funds Management and Other include the effect 
of interest rate risk positions and risk management activities, securities gains and losses including impairment charges, the 
provision for credit losses in excess of net loans charged off, tax planning strategies and certain executive compensation costs 
that are not attributed to the lines of business. 

BOK Financial allocates resources and evaluates performance of its lines of business after allocation of funds, actual net credit 
losses and capital costs. In addition, we measure the performance of our business lines after allocation of certain indirect 
expenses and taxes on statutory rates. The allocation for the prior comparable periods have been revised on a comparable basis. 

The cost of funds borrowed from the Funds Management unit by the operating lines of business is transfer priced at rates that 
approximate market rates for funds with similar duration. Market rates are generally based on the applicable LIBOR or interest 
rate swap rates, adjusted for prepayment risk. This method of transfer-pricing funds that support assets of the operating lines of 
business tends to insulate them from interest rate risk.

139

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The value of funds provided by the operating lines of business to the Funds Management unit is based on rates which 
approximate the wholesale market rates for funds with similar duration and re-pricing characteristics. Market rates are generally 
based on LIBOR or interest rate swap rates. The funds credit formula applied to deposit products with indeterminate maturities 
is established based on their re-pricing characteristics reflected in a combination of the short-term LIBOR rates and a moving 
average of an intermediate term swap rate, with an appropriate spread applied to both. Shorter duration products are weighted 
towards the short-term LIBOR rate and longer duration products are weighted towards intermediate swap rates. The expected 
duration ranges from 30 days for certain rate-sensitive deposits to five years.

Substantially all revenue is from domestic customers. No single external customer accounts for more than 10% of total revenue.

Net loans charged off and provision for credit losses represents net loans charged off as attributed to the lines of business and 
the provision for credit losses in excess of net charge-offs attributed to Funds Management and Other.

The operations of CoBiz, acquired on October 1, 2018 were allocated to the operating segments in the second quarter of 2019. 
Prior to April 1, 2019, CoBiz operations were included in Funds Management and other.

(19) Fair Value Measurements 

Fair value is defined by applicable accounting guidance as the price to sell an asset or transfer a liability in an orderly 
transaction between market participants in the principal market for the given asset or liability at the measurement date based on 
market conditions at that date. An orderly transaction assumes exposure to the market for a customary period for marketing 
activities prior to the measurement date and not a forced liquidation or distressed sale. Certain assets and liabilities are recorded 
in the Company’s financial statements at fair value. Some are recorded on a recurring basis and some on a non-recurring basis.

For some assets and liabilities, observable market transactions and market information might be available. For other assets and 
liabilities, observable market transactions and market information might not be available. A hierarchy for fair value has been 
established which categorizes into three levels the inputs to valuation techniques used to measure fair value. The three levels are 
as follows:

Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) - fair value is based on unadjusted quoted 
prices in active markets for identical assets or liabilities.

Significant Other Observable Inputs (Level 2) - fair value is based on significant other observable inputs which are 
generally determined based on a single price for each financial instrument provided to us by an applicable third-party 
pricing service and is based on one or more of the following:

•
•
•

•

Quoted prices for similar, but not identical, assets or liabilities in active markets;
Quoted prices for identical or similar assets or liabilities in inactive markets;
Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment 
speeds, loss severities, credit risks and default rates;
Other inputs derived from or corroborated by observable market inputs.

Significant Unobservable Inputs (Level 3) - fair value is based upon model-based valuation techniques for which at least 
one significant assumption is not observable in the market. 

Transfers between levels are recognized as of the end of the reporting period. There were no transfers in or out of quoted prices 
in active markets for identical instruments to significant other observable inputs or significant unobservable inputs during the 
year ended December 31, 2020 and 2019, respectively. Transfers between significant other observable inputs and significant 
unobservable inputs during the year ended December 31, 2020 and 2019 are included in the summary of changes in recurring 
fair values measured using unobservable inputs. 

The underlying methods used by the third-party pricing services are considered in determining the primary inputs used to 
determine fair values. Management has evaluated the methodologies employed by the third-party pricing services by comparing 
the price provided by the pricing service with other sources, including brokers' quotes, sales or purchases of similar instruments 
and discounted cash flows to establish a basis for reliance on the pricing service values. Significant differences between the 
pricing service provided value and other sources are discussed with the pricing service to understand the basis for their values. 
Based on all observable inputs, management may adjust prices obtained from third-party pricing services to more appropriately 
reflect the prices that would be received to sell assets or paid to transfer liabilities in orderly transactions in the current market. 
No significant adjustments were made to prices provided by third-party pricing services at December 31, 2020 and 2019.

Following is a description of the Company's valuation methodologies used for assets and liabilities measured on a recurring 
basis:

Securities

The fair values of trading, available for sale and fair value option securities are based on quoted prices for identical instruments 
in active markets, when available. If quoted prices for identical instruments are not available, fair values are based on 
significant other observable inputs such as quoted prices of comparable instruments or interest rates and credit spreads, yield 
curves, volatilities, prepayment speeds and loss severities. 

The fair value of certain available for sale and held-to-maturity municipal and other debt securities may be based on significant 
unobservable inputs. These significant unobservable inputs include limited observed trades, projected cash flows, current credit 
rating of the issuers and, when applicable, the insurers of the debt and observed trades of similar debt. Discount rates are 
primarily based on reference to interest rate spreads on comparable securities of similar duration and credit rating as determined 
by the nationally-recognized rating agencies adjusted for a lack of trading volume. Significant unobservable inputs are 
developed by investment securities professionals involved in the active trading of similar securities. A summary of significant 
inputs used to value these securities follows. A management committee composed of senior members from the Company's 
Capital Markets, Risk Management and Finance departments assess the appropriateness of these inputs quarterly.

Derivatives 

All derivative instruments are carried on the balance sheet at fair value. Fair values for exchange-traded contracts are based on 
quoted prices. Fair values for over-the-counter interest rate, commodity and foreign exchange contracts are based on valuations 
provided either by third-party dealers in the contracts, quotes provided by independent pricing services, or a third-party 
provided pricing model that uses significant other observable market inputs. 

Credit risk is considered in determining the fair value of derivative instruments. Management determines fair value adjustments 
based on various risk factors including but not limited to counterparty credit rating or equivalent loan grading, derivative 
contract notional size, price volatility of the underlying commodity, duration of the derivative contracts and expected loss 
severity. Expected loss severity is based on historical losses for similarly risk graded commercial loan customers. Decreases in 
counterparty credit rating or grading and increases in price volatility and expected loss severity all tend to increase the credit 
quality adjustment which reduces the fair value of asset contracts. 

We also consider our own credit risk in determining the fair value of derivative contracts. Changes in our credit rating would 
affect the fair value of our derivative liabilities. In the event of a credit downgrade, the fair value of our derivative liabilities 
would increase. 

Residential Mortgage Loans Held for Sale

Residential mortgage loans held for sale are carried on the balance sheet at fair value. The fair values of conforming residential 
mortgage loans held for sale are based upon quoted market prices of such loans sold in securitization transactions, including 
related unfunded loan commitments. The fair value of mortgage loans that are unable to be sold to U.S. government agencies is 
determined using quoted prices of loans that are sold in securitization transactions with a liquidity discount applied.

149

Fair Value of Assets and Liabilities Measured on a Non-Recurring Basis

Assets measured at fair value on a non-recurring basis include pension plan assets, which are based on quoted prices in active 
markets for identical instruments, collateral for certain impaired loans and real property and other assets acquired to satisfy 
loans, which are based primarily on comparisons to completed sales of similar assets. 

The following represents the carrying value of assets measured at fair value on a non-recurring basis and related losses recorded 
during the year. The carrying value represents only those assets with the balance sheet date for which the fair value was 
adjusted during the year:

The fair value of collateral-dependent nonaccruing loans and real estate and other repossessed assets and the related fair value 
adjustments are generally based on unadjusted third-party appraisals. Our appraisal review policies require appraised values to 
be supported by observed inputs derived principally from or corroborated by observable market data. Appraisals that are not 
based on observable inputs or that require significant adjustments or fair value measurements that are not based on third-party 
appraisals are considered to be based on significant unobservable inputs. Non-recurring fair value measurements of collateral-
dependent nonaccruing loans and real estate and other repossessed assets based on significant unobservable inputs are generally 
due to estimates of current fair values between appraisal dates. Significant unobservable inputs include listing prices for 
comparable assets, uncorroborated expert opinions or management's knowledge of the collateral or industry. Non-recurring fair 
value measurements of collateral dependent loans secured by mineral rights are generally determined by our internal staff of 
engineers on projected cash flows under current market conditions and are based on significant unobservable inputs. Projected 
cash flows are discounted according to risk characteristics of the underlying oil and gas properties. Assets are evaluated to 
demonstrate with reasonable certainty that crude oil, natural gas and natural gas liquids can be recovered from known oil and 
gas reservoirs under existing economic and operating conditions at current prices with existing conventional equipment, 
operating methods and costs. Significant unobservable inputs are developed by asset management and workout professionals 
and approved by senior Credit Administration executives.

evaluation of the effectiveness and design of the Company's disclosure controls and procedures (as that term is defined in Rules

procedures were effective in recording, processing, summarizing and reporting information required to be disclosed by the 
Company, within the time periods specified in the Securities and Exchange Commission's rules and forms.

reporting (as defined in Rule 13a-15(f) and 15d-15(f), as amended, of the Exchange Act) during the Company's fourth fiscal 
quarter that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting.
