BUSINESS

General

PART I

Prosperity Bancshares, Inc.®, a Texas corporation (the “Company”), was formed in 1983 as a vehicle to 

acquire the former Allied Bank in Edna, Texas, which was chartered in 1949 as The First National Bank of Edna 
and is now known as Prosperity Bank. The Company is a registered financial holding company that derives 
substantially all of its revenues and income from the operation of its bank subsidiary, Prosperity Bank® (“Prosperity 
Bank®” or the “Bank”). The Bank provides a wide array of financial products and services to small and medium-
sized businesses and consumers. As of December 31, 2017, the Bank operated 242 full service banking locations; 65 
in the Houston area, including The Woodlands; 29 in the South Texas area, including Corpus Christi and Victoria; 
33 in the Dallas/Fort Worth area; 22 in the East Texas area; 29 in the Central Texas area, including Austin and San 
Antonio; 34 in the West Texas area, including Lubbock, Midland-Odessa and Abilene; 16 in the Bryan/College 
Station area; 6 in the Central Oklahoma area; and 8 in the Tulsa, Oklahoma area. The Company’s principal 
executive office is located at Prosperity Bank Plaza, 4295 San Felipe in Houston, Texas and its telephone number is 
(281) 269-7199. The Company’s website address is www.prosperitybankusa.com.

The Company’s market consists of the communities served by its banking centers. The diverse nature of the 

economies in each local market served by the Company provides the Company with a varied customer base and 
allows the Company to spread its lending risk throughout a number of different industries including professional 
service firms and their principals, manufacturing, tourism, recreation, petrochemicals, farming and ranching. The 
Company’s market areas outside of Houston, Dallas, Corpus Christi, San Antonio, Lubbock, Austin, Tulsa and 
Oklahoma City are dominated by either small community banks or branches of larger regional banks. Management 
believes that the Company, through its responsive customer service and community banking philosophy, combined 
with the sophistication of a larger regional bank holding company, has a competitive advantage in its market areas 
and excellent growth opportunities through acquisitions, new banking center locations and additional business 
development.

Operating under a community banking philosophy, the Company seeks to develop broad customer 

relationships based on service and convenience while maintaining its prudent approach to lending and sound asset 
quality. The Company has grown through a combination of internal growth, the acquisition of community banks and 
branches of banks and the opening of new banking centers. As a result of its stable customer relationships, the 
Company is able to maintain a low cost of funds. Utilizing that and employing stringent cost controls, the Company 
has been profitable in every year of its existence, including the periods of adverse economic conditions in Texas and 
Oklahoma.

(2) The Company assumed approximately $3.6 billion of deposits and acquired certain assets, including 33 banking 

centers, from the Federal Deposit Insurance Corporation (“FDIC”), acting in its capacity as receiver for Franklin Bank.

Acquisition

Acquisition of Tradition Bancshares, Inc.—On January 1, 2016, the Company completed the acquisition of 

Tradition Bancshares, Inc. (“Tradition”) and its wholly-owned subsidiary Tradition Bank headquartered in Houston, 
Texas. Tradition Bank operated 7 banking offices in the Houston, Texas area, including its main office in Bellaire, 3 
banking centers in Katy and 1 banking center in The Woodlands.

As of December 31, 2015, Tradition, on a consolidated basis, reported total assets of $548.0 million, total 

loans of $253.3 million, total deposits of $488.9 million and shareholders’ equity of $43.1 million. Under the terms 
of the definitive agreement, the Company issued 679,528 shares of Company common stock plus $39.0 million in 
cash for all outstanding shares of Tradition capital stock, for a total merger consideration of $71.5 million, based on 
the Company’s closing stock price of $47.86 on December 31, 2015. As of December 31, 2017, the Company 
recognized goodwill of $32.0 million, which is calculated as the excess of both the consideration exchanged and 
liabilities assumed compared with the fair value of the assets acquired. Additionally, the Company recognized $5.6 
million of core deposit intangibles.

Officers and Associates

The Company’s directors and officers are important to the Company’s success and play a key role in the 

Company’s business development efforts by actively participating in civic and public service activities in the 
communities served by the Company.

The Company has invested heavily in its officers and associates by recruiting talented officers in its market 

areas and providing them with economic incentives. The senior management team has substantial experience in the 
Houston, Dallas, Austin, Bryan/College Station, East Texas, South Texas, West Texas, Oklahoma City and Tulsa 
markets and the surrounding communities in which the Company has a presence. Each banking center location is 
overseen by a local president or manager with knowledge of the community and lending expertise in the specific 
industries found in the community. The Company entrusts its banking center presidents and managers with authority 
and flexibility within general parameters with respect to product pricing and decision making in order to minimize 
the bureaucratic structure of larger banks. The Company operates each banking center as a separate profit center, 
maintaining separate data with respect to each banking center’s net interest income, efficiency ratio, deposit growth, 
loan growth and overall profitability. Banking center presidents and managers are accountable for performance in 
these areas and compensated accordingly. 

As of December 31, 2017, the Company and the Bank had 3,017 full-time equivalent associates, 790 of whom 

were officers of the Bank. The Company provides medical and hospitalization insurance to its full-time associates. 
The Company considers its relations with associates to be good. Neither the Company nor the Bank is a party to any 
collective bargaining agreement.

Banking Activities

The Company, through the Bank, offers a variety of traditional loan and deposit products to its customers, 

which consist primarily of consumers and small and medium-sized businesses. The Bank tailors its products to the 
specific needs of customers in a given market. At December 31, 2017, the Bank maintained approximately 595,500 
separate deposit accounts including certificates of deposit and 53,200 separate loan accounts. At December 31, 
2017, noninterest-bearing demand deposits were 31.6% of the Bank’s total deposits. For the year ended 
December 31, 2017, the Company’s average cost of funds was 0.33% and the Company’s average cost of deposits 
(excluding all borrowings) was 0.27%.

The Company has been an active real estate lender, with commercial real estate (including multifamily 

residential) and 1-4 family residential loans comprising 33.1% and 24.5%, respectively, of the Company’s total 
loans as of December 31, 2017. The Company also offers commercial loans, loans for automobiles and other 
consumer durables, home equity loans, debit and credit cards, internet banking and other cash management services, 
mobile banking, trust and wealth management, retail brokerage services, mortgage banking services and automated 
telephone banking. The Company offers businesses a broad array of loan products including term loans, lines of 
credit and loans for working capital, business expansion and the purchase of equipment and machinery; land 
development and interim construction loans for builders; and owner-occupied and non-owner occupied commercial 
real estate loans. 

By offering certificates of deposit, interest checking accounts, savings accounts and overdraft protection at 

competitive rates, the Company gives its depositors a full range of traditional deposit products.

As of December 31, 2017, the Company maintains a trust department with total assets of $2.15 billion, 
including managed assets of $1.75 billion. The trust department provides trust services in the Company’s various 
market areas. 

Business Strategies

The Company’s main objective is to increase deposits and loans through internal growth, as well as through 

acquisition opportunities, while maintaining efficiency, individualized customer service and maximizing 
profitability. To achieve this objective, the Company has employed the following strategic goals:

3

Continue Community Banking Emphasis. Although the Company has significantly grown in the last several 
years, it intends to continue operating as a community banking organization focused on meeting the specific needs 
of consumers and small and medium-sized businesses in its market areas. The Company provides a high degree of 
responsiveness combined with a wide variety of banking products and services. The Company staffs its banking 
centers with experienced bankers who possess lending expertise in the specific industries found in the given 
community, and gives them authority within general parameters to make certain pricing and credit decisions, 
avoiding the bureaucratic structure of larger banks. Each banking center has its own listed local business telephone 
number. Customers are served by a local banker with decision making authority.

Expand Market Share Through Internal Growth and a Disciplined Acquisition Strategy. The Company intends 
to continue seeking opportunities, both inside and outside its existing markets, to expand either by acquiring existing 
banks or branches of banks or by establishing new banking centers. All of the Company’s acquisitions have been 
accretive to earnings within 12 months after acquisition date and generally have supplied the Company with 
relatively low-cost deposits which have been used to fund the Company’s lending and investing activities. However, 
future acquisitions, if any, may not be accretive to earnings within any particular time period. Factors used by the 
Company to evaluate expansion opportunities include (1) the similarity in management and operating philosophies, 
(2) whether the acquisition will be accretive to earnings and enhance shareholder value, (3) whether the acquisition 
will strategically expand the Company’s geographic footprint and (4) the opportunity to enhance the Company’s 
market presence in existing market areas.

Increase Loan Volume and Diversify Loan Portfolio. While maintaining its prudent approach to lending, the 

Company has emphasized both new and existing loan products, focusing on increasing its commercial real estate 
and commercial loan portfolios. During 2017, the Company’s total loans increased from $9.62 billion to $10.02 
billion or 4.1%. Construction, land development and other land loans increased 19.4%, and represented 15.1% of the 
total loan portfolio as of December 31, 2017. Commercial real estate loans (including multifamily residential) 
increased 4.9%, and represented 33.1% of the total portfolio, as of December 31, 2017. 

Maintain Sound Asset Quality. The Company continues to maintain the sound asset quality that has been 

representative of its historical loan portfolio. As the Company continues to diversify and increase its lending 
activities and acquire loans in acquisitions, it may face higher risks of nonpayment and increased risks in the event 
of prolonged economic downturns. The Company intends to continue to employ the strict underwriting guidelines 
and comprehensive loan review process that have contributed to its low incidence of nonperforming assets and its 
minimal charge-offs in relation to its size.

Continue Focus on Efficiency. The Company plans to maintain its stringent cost control practices and policies. 

The Company has invested significantly in the infrastructure required to centralize many of its critical operations, 
such as data processing and loan processing. For its banking centers, which the Company operates as independent 
profit centers, the Company supplies complete support in the areas of loan review, loan processing, internal audit, 
compliance and training. Management believes that this centralized infrastructure can accommodate additional 
growth while enabling the Company to minimize operational costs through economies of scale.

Enhance Cross-Selling. The Company uses incentives and friendly competition to encourage cross-selling 

efforts and increase cross-selling results among its associates. Officers and associates have access to each 
customer’s existing and related account relationships and are better able to inform customers of additional products 
when customers visit or call the various banking centers or use their drive-in facilities. In addition, the Company 
includes product information in monthly statements and other mailings.

Competition

The banking business is highly competitive, and the profitability of the Company depends principally on its 

ability to compete in its market areas. The Company competes with other commercial banks, savings banks, savings 
and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and 
investment banking firms, asset-based nonbank lenders and certain other nonfinancial entities, including retail stores 
that may maintain their own credit programs and certain governmental organizations that may offer more favorable 
financing than the Company. The Company believes it has been able to compete effectively with other financial 
institutions by emphasizing customer service, technology and responsive decision-making with respect to loans, by 

4

establishing long-term customer relationships and building customer loyalty and by providing products and services 
designed to address the specific needs of its customers.

Supervision and Regulation

The supervision and regulation of bank holding companies and their subsidiaries is intended primarily for the 

protection of depositors, the Deposit Insurance Fund (“DIF”) of the FDIC and the banking system as a whole, and 
not for the protection of the bank holding company’s shareholders or creditors. The banking agencies have broad 
enforcement power over bank holding companies and banks including the power to impose substantial fines and 
other penalties for violations of laws and regulations.

The following description summarizes some of the laws to which the Company and the Bank are subject. 

References in this Annual Report on Form 10-K to applicable statutes and regulations are brief summaries thereof, 
do not purport to be complete, and are qualified in their entirety by reference to such statutes and regulations.

The Company

The Company is a financial holding company pursuant to the Gramm-Leach-Bliley Act and a bank holding 

company registered under the Bank Holding Company Act of 1956, as amended (“BHCA”). Accordingly, the 
Company is subject to supervision, regulation and examination by the Board of Governors of the Federal Reserve 
System (“Federal Reserve Board”). The Gramm-Leach-Bliley Act, the BHCA and other federal laws subject 
financial and bank holding companies to particular restrictions on the types of activities in which they may engage, 
and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of 
laws and regulations. Further, since the Company has securities registered with the Securities and Exchange 
Commission and traded on the New York Stock Exchange, it is also subject to the supervision and regulation of 
these organizations.

Regulatory Restrictions on Dividends. The Company is regarded as a legal entity separate and distinct from 
the Bank. The principal source of the Company’s revenues is dividends received from the Bank. As described in 
more detail below, federal and state law places limitations on the amount that banks may pay in dividends, which the 
Bank must adhere to when paying dividends to the Company. It is the policy of the Federal Reserve Board that bank 
holding companies should pay cash dividends on common stock only out of income available over the past year and 
only if the prospective rate of earnings retention is consistent with the organization’s expected capital needs and 
financial condition. The Federal Reserve Board’s policy provides that bank holding companies should not maintain 
a level of cash dividends that undermines the bank holding company’s ability to serve as a source of strength to its 
banking subsidiaries. The Federal Reserve Board is authorized to limit or prohibit the payment of dividends if, in the 
Federal Reserve Board’s opinion, the payment of dividends would constitute an unsafe or unsound practice in light 
of a bank holding company’s financial condition. In addition, the Federal Reserve Board has indicated that each 
bank holding company should carefully review its dividend policy, and has discouraged payment ratios that are at 
maximum allowable levels, which is the maximum dividend amount that may be issued and allow the company to 
still maintain its target Tier 1 capital ratio, unless both asset quality and capital are very strong.

Stress Testing. In accordance with rules adopted by the Federal Reserve Board pursuant to the Dodd-Frank 

Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), institutions with average total 
consolidated assets greater than $10 billion, such as the Company and the Bank, are required to conduct an annual 
company-run stress test of capital and consolidated earnings and losses under one base and at least two stress 
scenarios provided by bank regulatory agencies. Public disclosure of summary stress test results under the severely 
adverse scenario will occur between October 15 and October 31. The Company’s capital ratios reflected in the stress 
test calculations are an important factor considered by the Federal Reserve Board in evaluating the capital adequacy 
of the Company and the Bank and determining whether proposed payments of dividends or stock repurchases may 
be an unsafe or unsound practice.

Source of Strength. Under Federal Reserve Board policy, a bank holding company has historically been 
required to act as a source of financial strength to each of its banking subsidiaries. The Dodd-Frank Act codified this 
policy as a statutory requirement. Under this requirement, the Company is expected to commit resources to support 
the Bank, including support at times when the Company may not be in a financial position to provide such 
resources. Any capital loans by a bank holding company to any of its subsidiary banks are subordinate in right of 

5

payment to deposits and to certain other indebtedness of such subsidiary banks. As discussed below, a bank holding 
company, in certain circumstances, could be required to guarantee the capital plan of an undercapitalized banking 
subsidiary.

In the event of a bank holding company’s bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, the 

trustee will be deemed to have assumed and is required to cure immediately any deficit under any commitment by 
the debtor holding company to any of the federal banking agencies to maintain the capital of an insured depository 
institution. Any claim for breach of such obligation will generally have priority over most other unsecured claims.

Scope of Permissible Activities. Under the BHCA, bank holding companies generally may not acquire a direct 

or indirect interest in or control of more than 5% of the voting shares of any company that is not a bank or bank 
holding company and may not engage in activities other than those of banking, managing or controlling banks or 
furnishing services to or performing services for its subsidiaries, except that it may engage in, directly or indirectly, 
certain activities that the Federal Reserve Board has determined to be so closely related to banking or managing and 
controlling banks as to be a proper incident thereto. In approving acquisitions or the addition of activities, the 
Federal Reserve Board considers, among other things, whether the acquisition or the additional activities can 
reasonably be expected to produce benefits to the public, such as greater convenience, increased competition, or 
gains in efficiency, that outweigh such possible adverse effects as undue concentration of resources, decreased or 
unfair competition, conflicts of interest or unsound banking practices.

Notwithstanding the foregoing, the Gramm-Leach-Bliley Act eliminated the barriers to affiliations among 

banks, securities firms, insurance companies and other financial service providers and permits bank holding 
companies to become financial holding companies and thereby affiliate with securities firms and insurance 
companies and engage in other activities that are financial in nature. The Gramm-Leach-Bliley Act defines 
“financial in nature” to include securities underwriting, dealing and market making; sponsoring mutual funds and 
investment companies; insurance underwriting and agency; merchant banking activities; and activities that the 
Federal Reserve Board has determined to be closely related to banking. Generally, no regulatory approval will be 
required for a financial holding company, such as the Company, to acquire a company, other than a bank or savings 
association, engaged in activities that are financial in nature or incidental to activities that are financial in nature as 
determined by the Federal Reserve Board.

The Company’s financial holding company status depends upon it maintaining its status as “well capitalized” 
and “well managed” under applicable Federal Reserve Board regulations. If a financial holding company ceases to 
meet these requirements, the Federal Reserve Board may impose corrective capital and/or managerial requirements 
on the financial holding company and place limitations on its ability to conduct the broader financial activities 
permissible for financial holding companies. Until the financial holding company returns to compliance, it may not 
acquire a company engaged in such financial activities without prior approval of the Federal Reserve Board. In 
addition, the Federal Reserve Board may require divestiture of the holding company’s depository institutions and/or 
its non-bank subsidiaries if the deficiencies persist.

While the Federal Reserve Board is the “umbrella” regulator for financial holding companies and has the 

power to examine banking organizations engaged in new activities, regulation and supervision of activities which 
are financial in nature or determined to be incidental to such financial activities will be handled along functional 
lines. Accordingly, activities of subsidiaries of a financial holding company will be regulated by the agency or 
authorities with the most experience regulating that activity as it is conducted in a financial holding company.

Safe and Sound Banking Practices. Bank holding companies are not permitted to engage in unsafe and 
unsound banking practices. The Federal Reserve Board’s Regulation Y, for example, generally requires a holding 
company to give the Federal Reserve Board prior notice of any redemption or repurchase of its own equity securities 
if the consideration to be paid, together with the consideration paid for any repurchases or redemptions in the 
preceding year, is equal to 10% or more of the company’s consolidated net worth. The Federal Reserve Board may 
oppose the transaction if it believes that the transaction would constitute an unsafe or unsound practice or would 
violate any law or regulation. Depending upon the circumstances, the Federal Reserve Board could take the position 
that paying a dividend would constitute an unsafe or unsound banking practice.

6

The Federal Reserve Board has broad authority to prohibit activities of bank holding companies and their 
nonbanking subsidiaries which represent unsafe and unsound banking practices or which constitute violations of 
laws or regulations, and can assess civil money penalties for certain activities conducted on a knowing and reckless 
basis if those activities caused a substantial loss to a depository institution. The penalties can be in excess of $1.0 
million for each day the activity continues.

Anti-Tying Restrictions. Bank holding companies and their affiliates are prohibited from tying the provision of 

certain services, such as extensions of credit, to other services offered by a holding company or its affiliates.

Basel III Capital Adequacy Requirements. In July 2013, the Federal Reserve Board and the FDIC published 

the Basel III Capital Rules establishing a new comprehensive capital framework for U.S. banking organizations. The 
rules implemented the Basel Committee’s December 2010 framework known as “Basel III” for strengthening 
international capital standards as well as certain provisions of the Dodd-Frank Act. The Basel III Capital Rules 
define the components of capital and address other issues affecting the numerator in banking institutions’ regulatory 
capital ratio calculations and also address risk weights and other issues affecting the denominator. The Basel III 
Capital Rules became effective for the Company and the Bank on January 1, 2015, subject to a phase-in period for 
certain provisions.

The Basel III Capital Rules, among other things, include a capital measure called “Common Equity Tier 1” 

(“CET1”) and specify that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting 
specified requirements. The Basel III Capital Rules also provide for a number of deductions from and adjustments to 
CET1. These include, for example, the requirement that certain deferred tax assets and significant investments in 
non-consolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of 
CET1 or all such items, in the aggregate, exceed 15% of CET1. Implementation of the deductions and other 
adjustments to CET1 began on January 1, 2015 and are being phased-in over a four-year transition period 
(beginning at 40% on January 1, 2015 and increasing by an additional 20% per year thereafter).  In October 2017, 
however, the banking agencies proposed rules to modify the thresholds for deductions from CET1 and in connection 
with that rule proposal, in November 2017, extended the transition period for financial institutions with assets less 
than $50 billion, like the Company and the Bank. Under the Basel III Capital Rules, trust preferred securities no 
longer included in Tier 1 capital of bank holding companies may be included as Tier 2 capital on a permanent basis.

The Basel III Capital Rules also require a capital conservation buffer, composed entirely of CET1 that is 
designed to absorb losses during periods of economic stress and has the effect of increasing the minimum required 
risk-weighted capital ratios, but has no effect on the leverage ratio. The implementation of the capital conservation 
buffer began on January 1, 2016 at the 0.625% level and is being phased in over a four-year period (increasing by 
that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The required phase-in buffer 
during 2017 was 1.25%.  The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is 
applicable to only certain covered institutions and does not have any current applicability to the Company or the 
Bank. Banking institutions with a ratio of CET1 to risk-weighted assets below the effective minimum (4.5% plus the 
capital conservation buffer and, if applicable, the countercyclical capital buffer) face constraints on dividends, equity 
repurchases and compensation based on the amount of the shortfall.

The minimum capital ratios under the Basel III Capital Rule, including the capital conservation buffer, that 
were effective as of January 1, 2017 are (1) 5.75% CET1 to risk-weighted assets, (2) 7.25% Tier 1 capital to risk-
weighted assets, (3) 9.25% total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets and (4) 4.0% Tier 1 
capital to average quarterly assets as reported on consolidated financial statements (known as the “leverage ratio”). 
As of December 31, 2017, the Company’s ratio of CET1 to risk-weighted assets was 15.08%, Tier 1 capital to risk-
weighted assets was 15.08%, total capital to risk-weighted assets was 15.74% and Tier 1 capital to average quarterly 
assets was 9.31%.

When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company to maintain an 

additional capital conservation buffer of 2.5% CET1, effectively resulting in minimum ratios of (1) CET1 to risk-
weighted assets of 7.0%, (2) Tier 1 capital to risk-weighted assets of 8.5%, (3) total capital to risk-weighted assets 
of 10.5% and (4) a leverage ratio of 4.0%.

7

With respect to the Bank, the Basel III Capital Rules also revise the “prompt corrective action” regulations as 

discussed below under “The Bank—Corrective Measures for Capital Deficiencies.”

The Basel III Capital Rules prescribe a standardized approach for risk weightings that expands the risk-

weighting categories from the general risk-based capital rules to a larger and more risk-sensitive number of 
categories, depending on the nature of the assets, generally ranging from 0% for U.S. government and agency 
securities, to 600% for certain equity exposures, and resulting in higher risk weights for a variety of asset categories.

The federal banking agencies’ risk-based and leverage capital ratios are minimum supervisory ratios generally 

applicable to banking organizations that meet certain specified criteria. Banking organizations not meeting these 
criteria are expected to operate with capital positions well above the minimum ratios. The federal bank regulatory 
agencies may set capital requirements for a particular banking organization that are higher than the minimum ratios 
when circumstances warrant. Federal Reserve Board guidelines also provide that banking organizations 
experiencing internal growth or making acquisitions will be expected to maintain strong capital positions 
substantially above the minimum supervisory levels, without significant reliance on intangible assets.

Liquidity Requirements. Historically, regulation and monitoring of bank and bank holding company liquidity 
has been addressed as a supervisory matter, without required formulaic measures. The Basel III liquidity framework 
requires banks and bank holding companies to measure their liquidity against specific liquidity tests that, although 
similar in some respects to liquidity measures historically applied by banks and regulators for management and 
supervisory purposes, are now required by regulation.

One test, referred to as the liquidity coverage ratio (“LCR”), is designed to ensure that a banking entity 
maintains an adequate level of unencumbered high-quality liquid assets equal to the entity’s expected net cash 
outflow for a 30-day time horizon (or, if greater, 25% of its expected total cash outflow) under an acute liquidity 
stress scenario. The other test, referred to as the net stable funding ratio (“NSFR”), is designed to promote more 
medium- and long-term funding of the assets and activities of banking entities over a one-year time horizon. Neither 
the LCR rule nor the proposed NSFR rule apply to U.S. banking organizations with less than $50 billion in total 
consolidated assets such as the Company and the Bank.

Imposition of Liability for Undercapitalized Subsidiaries. Bank regulators are required to take “prompt 
corrective action” to resolve problems associated with insured depository institutions whose capital declines below 
certain levels. In the event an institution becomes “undercapitalized,” it must submit a capital restoration plan. The 
capital restoration plan will not be accepted by the regulators unless each company having control of the 
undercapitalized institution guarantees the subsidiary’s compliance with the capital restoration plan up to a certain 
specified amount. Any such guarantee from a depository institution’s holding company is entitled to a priority of 
payment in bankruptcy.

The aggregate liability of the holding company of an undercapitalized bank is limited to the lesser of 5% of 
the institution’s assets at the time it became undercapitalized or the amount necessary to cause the institution to be 
“adequately capitalized.” The bank regulators have greater power in situations where an institution becomes 
“significantly” or “critically” undercapitalized or fails to submit a capital restoration plan. For example, a bank 
holding company controlling such an institution can be required to obtain prior Federal Reserve Board approval of 
proposed dividends, or might be required to consent to a consolidation or to divest the troubled institution or other 
affiliates.

Acquisitions by Bank Holding Companies. The BHCA requires every bank holding company to obtain the 
prior approval of the Federal Reserve Board before it may acquire all or substantially all of the assets of any bank, or 
ownership or control of any voting shares of any bank, if after such acquisition it would own or control, directly or 
indirectly, 5% or more of the voting shares of such bank. In approving bank acquisitions by bank holding 
companies, the Federal Reserve Board is required to consider, among other things, the financial and managerial 
resources and future prospects of the bank holding company and the banks concerned, the convenience and needs of 
the communities to be served and various competitive factors.

8

Control Acquisitions. The Change in Bank Control Act (“CBCA”) prohibits a person or group of persons from 

acquiring “control” of a bank holding company unless the Federal Reserve Board has been notified and has not 
objected to the transaction. Under a rebuttable presumption established by the Federal Reserve Board, the 
acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered 
under Section 12 of the Exchange Act, such as the Company, would, under the circumstances set forth in the 
presumption, constitute acquisition of control of the Company.

In addition, a person may not acquire 25% (5% in the case of an acquiror that is a bank holding company) or 

more of a bank holding company’s or bank’s voting securities, or otherwise obtain control or a controlling influence 
over a bank holding company or bank without the approval of the Federal Reserve Board. In 2008, the Federal 
Reserve Board issued a policy statement on equity investments in bank holding companies and banks, which allows 
the Federal Reserve Board to generally be able to conclude that an entity’s investment is not “controlling” if the 
entity does not own in excess of 15% of the voting power and 33% of the total equity of the bank holding company 
or bank. Depending on the nature of the overall investment and the capital structure of the banking organization, the 
Federal Reserve Board will permit, based on the policy statement, noncontrolling investments in the form of voting 
and nonvoting shares that represent in the aggregate (1) less than one-third of the total equity of the banking 
organization (and less than one-third of any class of voting securities, assuming conversion of all convertible 
nonvoting securities held by the entity) and (2) less than 15% of any class of voting securities of the banking 
organization.

The Volcker Rule. The Volcker Rule under the Dodd-Frank Act prohibits banks and their affiliates from 
engaging in proprietary trading and investing in and sponsoring certain hedge funds and private equity funds. Since 
neither the Company nor the Bank engages in the types of trading or investing covered by the Volcker Rule, the 
Volcker Rule does not currently have any effect on the operations of the Company or the Bank.

The Bank

The Bank is a Texas-chartered banking association, the deposits of which are insured by the DIF of the FDIC. 

The Bank is not a member of the Federal Reserve System, therefore the Bank is subject to supervision and 
regulation by the FDIC and the Texas Department of Banking. Such supervision and regulation subject the Bank to 
special restrictions, requirements, potential enforcement actions and periodic examination by the FDIC and the 
Texas Department of Banking. Because the Federal Reserve Board regulates the Company, the Federal Reserve 
Board also has supervisory authority which affects the Bank. Further, because the Bank has total assets of over $10 
billion, the Bank is also subject to supervision and regulation by the Consumer Financial Protection Bureau 
(“CFPB”). The CFPB regulates the offering and provision of consumer financial products and services under the 
federal consumer financial laws.

Equivalence to National Bank Powers. The Texas Constitution, as amended in 1986, provides that a Texas-
chartered bank has the same rights and privileges that are or may be granted to national banks domiciled in Texas. 
To the extent that the Texas laws and regulations may have allowed state-chartered banks to engage in a broader 
range of activities than national banks, the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) has 
operated to limit this authority. FDICIA provides that no state bank or subsidiary thereof may engage as principal in 
any activity not permitted for national banks, unless the institution complies with applicable capital requirements 
and the FDIC determines that the activity poses no significant risk to the DIF. In general, statutory restrictions on the 
activities of banks are aimed at protecting the safety and soundness of depository institutions.

Financial Modernization. Under the Gramm-Leach-Bliley Act, a national bank may establish a financial 
subsidiary and engage, subject to limitations on investment, in activities that are financial in nature, other than 
insurance underwriting as principal, insurance company portfolio investment, real estate development, real estate 
investment, annuity issuance and merchant banking activities. To do so, a bank must be well capitalized, well 
managed and have a CRA rating of satisfactory or better. Subsidiary banks of a financial holding company or 
national banks with financial subsidiaries must remain well capitalized and well managed in order to continue to 
engage in activities that are financial in nature without regulatory actions or restrictions, which could include 
divestiture of the financial-in-nature subsidiary or subsidiaries. In addition, a financial holding company or a bank 
may not acquire a company that is engaged in activities that are financial in nature unless each of the subsidiary 
banks of the financial holding company or the bank has a CRA rating of satisfactory or better.

9

Although the powers of state chartered banks are not specifically addressed in the Gramm-Leach-Bliley Act, 

Texas-chartered banks such as the Bank, will have the same if not greater powers as national banks through the 
parity provision contained in the Texas Constitution.

Branching. Pursuant to the Dodd-Frank Act, banks are permitted to engage in de novo interstate branching if 

the laws of the state where the new branch is to be established would permit the establishment of the branch if it 
were chartered by such state, subject to applicable regulatory review and approval requirements. The Dodd-Frank 
Act also modified certain regulatory requirements for interstate mergers and acquisitions, including that the 
acquiring bank must be well capitalized and well managed. Texas law provides that a Texas-chartered bank can 
establish a branch anywhere in Texas or any other state, subject to federal law requirements, provided that the 
branch is approved in advance by the Texas Department of Banking. The branch must also be approved by the 
FDIC, which considers a number of factors, including financial history, capital adequacy, earnings prospects, 
character of management, needs of the community and consistency with corporate powers.

Restrictions on Transactions with Affiliates and Insiders. Transactions between the Bank and its nonbanking 

affiliates, including the Company, are subject to Section 23A and Section 23B of the Federal Reserve Act. In 
general, Section 23A imposes limits on the amount of such transactions to 10% of the Bank’s capital stock and 
surplus and requires that such transactions be secured by designated amounts of specified collateral. It also limits the 
amount of advances to third parties which are collateralized by the securities or obligations of the Company or its 
subsidiaries. Section 23B generally requires that certain transactions between the Bank and its affiliates be on terms 
substantially the same, or at least as favorable to the Bank, as those prevailing at the time for comparable 
transactions with or involving other nonaffiliated persons.

Loans to directors, executive officers, principal shareholders and their related interests (collectively referred to 
herein as “insiders”) are subject to restrictions contained in the Federal Reserve Act and Regulation O, which apply 
to all insured institutions and their subsidiaries and holding companies. Insiders are subject to enforcement actions 
for knowingly accepting loans in violation of applicable restrictions.

Restrictions on Distribution of Subsidiary Bank Dividends and Assets. Dividends paid by the Bank have 

provided a substantial part of the Company’s operating funds and for the foreseeable future it is anticipated that 
dividends paid by the Bank to the Company will continue to be the Company’s principal source of operating funds. 
Capital adequacy requirements serve to limit the amount of dividends that may be paid by the Bank. Under federal 
law, the Bank cannot pay a dividend if, after paying the dividend, the Bank will be “undercapitalized.” The FDIC 
may declare a dividend payment to be unsafe and unsound even though the Bank would continue to meet its capital 
requirements after the dividend. The Bank is also subject to limitations on the payment of dividends under Texas 
law. Because the Company is a legal entity separate and distinct from its subsidiaries, its right to participate in the 
distribution of assets of any subsidiary upon the subsidiary’s liquidation or reorganization will be subject to the prior 
claims of the subsidiary’s creditors. In the event of a liquidation or other resolution of an insured depository 
institution, the claims of depositors and other general or subordinated creditors are entitled to a priority of payment 
over the claims of holders of any obligation of the institution to its shareholders, including any depository institution 
holding company (such as the Company) or any shareholder or creditor thereof.

Consumer Financial Protection. The Bank is subject to a number of federal and state consumer protection 
laws that extensively govern its relationship with its 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 the Bank’s ability to raise interest rates and subject the Bank 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 and civil money penalties in each jurisdiction in which the Bank operates. Failure to comply with consumer 

10

protection requirements may also result in the Bank’s failure to obtain any required regulatory approval for merger 
or other acquisition transactions the Bank may wish to pursue or its prohibition from engaging in such transactions 
even if approval is not required.

The Dodd-Frank Act established the CFPB, which has supervisory, examination and enforcement authority 

over depository institutions with total assets of $10 billion or greater and other providers of consumer financial 
products or services. The CFPB has broad rulemaking authority for a wide range of federal consumer financial laws, 
including, among other things, the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB 
can issue cease-and-desist orders against banks and other entities that violate federal consumer financial laws and 
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.

Customer Information Security. The federal banking agencies have adopted guidelines for safeguarding 
confidential, personal, nonpublic customer information. These guidelines require each financial institution, under the 
supervision and ongoing oversight of its board of directors or an appropriate committee thereof, to create, implement 
and maintain a comprehensive written information security program designed to ensure the security and 
confidentiality of customer information, protect against any anticipated threats or hazard to the security or integrity 
of such information and protect against unauthorized access to or use of such information that could result in 
substantial harm or inconvenience to any customer. The Bank has adopted a customer information security program 
to comply with these requirements.

Examinations. The FDIC periodically examines and evaluates state non-member banks, like the Bank. The 

Texas Department of Banking also conducts examinations of Texas-chartered banks, but may accept the results of a 
federal examination in lieu of conducting an independent examination. Additionally, the FDIC and Texas 
Department of Banking may elect to conduct a joint examination. Because the Bank has total assets of over $10 
billion, the CFPB also has examination authority with respect to the Bank’s compliance with federal consumer 
protection laws. 

Capital Adequacy Requirements. The FDIC has adopted regulations establishing minimum requirements for 

the capital adequacy of insured institutions. The FDIC may establish higher minimum requirements if, for example, 
a bank has previously received special attention or has a high susceptibility to interest rate risk.

The FDIC’s risk-based capital guidelines generally require state banks to have minimum ratios of CET1 to 

risk-weighted assets of 4.5%, Tier 1 capital to total risk-weighted assets of 6.0% and total capital to total risk-
weighted assets of 8.0%. The capital categories have the same definitions for the Bank as for the Company. As of 
December 31, 2017, the Bank’s ratio of CET1 to risk-weighted assets was 14.98%, Tier 1 capital to total risk-
weighted assets was 14.98% and its ratio of total capital to total risk-weighted assets was 15.65%.

The FDIC’s leverage guidelines require state banks to maintain Tier 1 capital of no less than 4.0% of average 
total assets. As of December 31, 2017, the Bank’s ratio of Tier 1 capital to average quarterly assets (leverage ratio) 
was 9.25%.

Corrective Measures for Capital Deficiencies. The federal banking regulators are required to take “prompt 

corrective action” with respect to capital-deficient institutions. Agency regulations define, for each capital category, 
the levels at which institutions are “well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly 
undercapitalized” and “critically undercapitalized.”

(cid:129)

(cid:129)

A bank is “well capitalized” if it has a total risk-based capital ratio of 10.0% or higher; a CET1 capital 
ratio of 6.5% or higher; a Tier 1 risk-based capital ratio of 8.0% or higher; a leverage ratio of 5.0% or 
higher; and is not subject to any written agreement, order or directive requiring it to maintain a specific 
capital level for any capital measure.

A bank is “adequately capitalized” if it has a total risk-based capital ratio of 8.0% or higher; a CET1 
capital ratio of 4.5% or higher; a Tier 1 risk-based capital ratio of 6.0% or higher; a leverage ratio of 
4.0% or higher; and does not meet the criteria for a well capitalized bank.

11

(cid:129)

(cid:129)

(cid:129)

A bank is “undercapitalized” if it has a total risk-based capital ratio of less than 8.0%; a CET1 capital 
ratio less than 4.5%; a Tier 1 risk-based capital ratio of less than 6.0% or a leverage ratio of less than 
4.0%.

A bank is “significantly undercapitalized” if it has a total risk-based capital ratio of less than 6.0%; a 
CET1 capital ratio less than 3.0%; a Tier 1 risk-based capital ratio of less than 4.0% or a leverage ratio 
of less than 3.0%.

A bank is “critically undercapitalized” if it has a tangible equity ratio to total assets that is equal to or 
less than 2.0%.

At December 31, 2017, the Bank was classified as “well-capitalized” for purposes of the FDIC’s prompt 

corrective action regulations in effect as of such date.

In addition to requiring undercapitalized institutions to submit a capital restoration plan, agency regulations 
contain broad restrictions on certain activities of undercapitalized institutions including asset growth, acquisitions, 
branch establishment and expansion into new lines of business. With certain exceptions, an insured depository 
institution is prohibited from making capital distributions, including dividends, and is prohibited from paying 
management fees to control persons if the institution would be undercapitalized after any such distribution or 
payment.

As an institution’s capital decreases, the FDIC’s enforcement powers become more severe. A significantly 
undercapitalized institution is subject to mandated capital raising activities, restrictions on interest rates paid and 
transactions with affiliates, removal of management and other restrictions. The FDIC has only very limited 
discretion in dealing with a critically undercapitalized institution and is virtually required to appoint a receiver or 
conservator.

Banks with risk-based capital and leverage ratios below the required minimums may also be subject to certain 

administrative actions, including the termination of deposit insurance upon notice and hearing, or a temporary 
suspension of insurance without a hearing in the event the institution has no tangible capital.

Deposit Insurance Assessments. The deposits of the Bank are insured up to applicable limits by the DIF, and 
the Bank must pay deposit insurance assessments to the FDIC for such deposit insurance protection. A depository 
institution’s DIF assessment is calculated by multiplying its assessment rate by the assessment base, which is 
defined as the average consolidated total assets less the average tangible equity of the depository institution. The 
initial base assessment rate is based on its capital level and CAMELS ratings, certain financial measures to assess an 
institution’s ability to withstand asset related stress and funding related stress and, in some cases, additional 
discretionary adjustments by the FDIC to reflect additional risk factors. 

The FDIC’s current DIF restoration plan is designed to ensure that the fund reserve ratio reaches 1.35% by 

September 30, 2020, as required by the Dodd-Frank Act. At least semi-annually, the FDIC updates its loss and 
income projections for the fund and, if needed, increases or decreases assessment rates, following notice-and-
comment rulemaking, if required. 

In August 2016, the FDIC announced that the DIF reserve ratio had surpassed 1.15% as of June 30, 2016. As a 

result, beginning in the third quarter of 2016, the initial assessment ranges for all institutions were adjusted 
downward such that the initial base deposit insurance assessment rate ranges from three to 30 basis points on an 
annualized basis (basis points representing cents per $100 of assessable assets). After the effect of potential base-rate 
adjustments, the total base assessment rate could range from 1.5 to 40 basis points on an annualized basis. 

Interchange Fees. Under the Durbin Amendment to the Dodd-Frank Act, the Federal Reserve Board adopted 

rules establishing standards for assessing whether the interchange fees that may be charged with respect to certain 
electronic debit transactions are “reasonable and proportional” to the costs incurred by issuers for processing such 
transactions. Interchange fees, or “swipe” fees, are charges that merchants pay to the Bank and other card-issuing 
banks for processing electronic payment transactions. Federal Reserve Board rules applicable to financial 
institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an 

12

electronic debit transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the 
transaction. An upward adjustment of no more than 1 cent to an issuer’s debit card interchange fee is allowed if the 
card issuer develops and implements policies and procedures reasonably designed to achieve certain fraud-
prevention standards. The Federal Reserve Board also has rules governing routing and exclusivity that require 
issuers to offer at least two unaffiliated networks for routing transactions on each debit or prepaid product.

Concentrated Commercial Real Estate Lending Regulations. The federal banking agencies, including the 
FDIC, have promulgated guidance governing financial institutions with concentrations in commercial real estate 
lending. The guidance provides that a bank has a concentration in commercial real estate lending if (1) total reported 
loans for construction, land development and other land represent 100% or more of total capital or (2) total reported 
loans secured by multifamily and non-farm residential properties and loans for construction, land development and 
other land represent 300% or more of total capital and the bank’s commercial real estate loan portfolio has increased 
50% or more during the prior 36 months. Owner occupied loans are excluded from this second category. If a 
concentration is present, management must employ heightened risk management practices that address the following 
key elements: including board and management oversight and strategic planning, portfolio management, 
development of underwriting standards, risk assessment and monitoring through market analysis and stress testing, 
and maintenance of increased capital levels as needed to support the level of commercial real estate lending.

Community Reinvestment Act. The Community Reinvestment Act of 1977 (“CRA”) and the regulations issued 

thereunder are intended to encourage banks to help meet the credit needs of their communities, including low and 
moderate income neighborhoods, consistent with the safe and sound operations of the banks. These regulations also 
provide for regulatory assessment of a bank’s CRA record when considering applications to establish branches, 
merger applications and applications to acquire the assets and assume the liabilities of another bank. The Financial 
Institutions Reform, Recovery, and Enforcement Act (“FIRREA”) requires federal banking agencies to make public 
a rating of a bank’s performance under the CRA. In the case of a financial holding company or a bank holding 
company, the CRA performance records of the banks involved in the transaction are reviewed in connection with the 
filing of an application to acquire ownership or control of shares or assets of a bank or to merge with any other bank 
holding company. An unsatisfactory record can substantially delay or block the transaction.

Anti-Money Laundering and Anti-Terrorism Legislation. A major focus of governmental policy on financial 

institutions in recent years has been aimed at combating money laundering and terrorist financing. The USA 
PATRIOT Act of 2001 (the “USA Patriot Act”) substantially broadened the scope of United States anti-money 
laundering laws and regulations by imposing significant new compliance and due diligence obligations, creating 
new crimes and penalties and expanding the extra-territorial jurisdiction of the United States. The United States 
Treasury Department has issued and, in some cases, proposed a number of regulations that apply various 
requirements of the USA Patriot Act to financial institutions. These regulations impose obligations on financial 
institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering 
and terrorist financing and to verify the identity of their customers. The regulations also impose specific due 
diligence requirements on financial institutions that maintain correspondent or private banking relationships with 
non-U.S. financial institutions or persons. Failure of a financial institution to maintain and implement adequate 
programs to combat money laundering and terrorist financing, or to comply with all of the relevant laws or 
regulations, could have serious legal and reputational consequences for the institution and could block or 
substantially delay a merger or other acquisition transaction.

Office of Foreign Assets Control Regulation. The United States has imposed economic sanctions that affect 

transactions with designated foreign countries, nationals and others. These are typically known as the “OFAC” rules 
based on their administration by the U.S. Treasury Department Office of Foreign Assets Control (“OFAC”). The 
OFAC-administered sanctions targeting countries take many different forms. Generally, however, they contain one 
or more of the following elements: (1) restrictions on trade with or investment in a sanctioned country, including 
prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on 
“U.S. persons” engaging in financial transactions relating to making investments in, or providing investment-related 
advice or assistance to, a sanctioned country; and (2) a blocking of assets in which the government or specially 
designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to 
U.S. jurisdiction (including property in the possession or control of U.S. persons). Blocked assets (e.g., property and 
bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. 

13

Failure to comply with these sanctions could have serious legal and reputational consequences, including substantial 
delay or blocking of a merger or other acquisition transaction.

Incentive Compensation. In June 2010, the Federal Reserve Board, OCC and FDIC issued comprehensive 
final guidance on incentive compensation policies intended to ensure that the incentive compensation policies of 
banking organizations do not undermine the safety and soundness of such organizations by encouraging excessive 
risk-taking. The guidance, which covers all employees that have the ability to materially affect the risk profile of an 
organization, either individually or as part of a group, is based upon the key principles that a banking organization’s 
incentive compensation arrangements should (1) provide incentives that do not encourage risk-taking beyond the 
organization’s ability to effectively identify and manage risks, (2) be compatible with effective internal controls and 
risk management and (3) be supported by strong corporate governance, including active and effective oversight by 
the organization’s Board of Directors. 

These three principles are incorporated into the proposed revised rules on incentive-based payment 

arrangements at specified covered institutions released in May 2016 by a number of federal agencies, including the 
Federal Reserve Board, FDIC and SEC.  The proposed revised rules would establish general qualitative 
requirements applicable to all covered institutions, including the Company and the Bank, that have at least $1 billion 
in total assets, which would include (1) prohibiting incentive arrangements that encourage inappropriate risks by 
providing excessive compensation; (2) prohibiting incentive arrangements that encourage inappropriate risks that 
could lead to a material financial loss; (3) establishing requirements for performance measures to appropriately 
balance risk and reward; (4) requiring Board of Director oversight of incentive arrangements; and (5) mandating 
appropriate record-keeping. Under the proposed rule, larger financial institutions with total consolidated assets of at 
least $50 billion would also be subject to additional requirements.

The Federal Reserve Board and FDIC review, as part of the regular, risk-focused examination process, the 

incentive compensation arrangements of banking organizations, such as the Company, that are not “large, complex 
banking organizations.” These reviews are tailored to each organization based on the scope and complexity of the 
organization’s activities and the prevalence of incentive compensation arrangements. The findings of this 
supervisory initiative will be included in reports of examination. Deficiencies will be incorporated into the 
organization’s supervisory ratings, which can affect the organization’s ability to make acquisitions and take other 
actions. Enforcement actions may be taken against a banking organization if its incentive compensation 
arrangements, or related risk-management control or governance processes, pose a risk to the organization’s safety 
and soundness and the organization is not taking prompt and effective measures to correct the deficiencies.

Legislative and Regulatory Initiatives

From time to time, various legislative and regulatory initiatives are introduced in Congress and state 
legislatures, as well as by regulatory agencies. Such initiatives may include proposals to expand or contract the 
powers of bank holding companies and depository institutions or proposals to substantially change the financial 
institution regulatory system. Such legislation could change banking statutes and the operating environment of the 
Company in substantial and unpredictable ways. If enacted, such legislation could increase or decrease the cost of 
doing business, limit or expand permissible activities or affect the competitive balance among banks, savings 
associations, credit unions, and other financial institutions. The Company cannot predict whether any such 
legislation will be enacted, and, if enacted, the effect that it, or any implementing regulations, would have on the 
financial condition or results of operations of the Company. A change in statutes, regulations or regulatory policies 
applicable to the Company or the Bank could have a material effect on the Company’s business, financial condition 
and results of operations.  In addition, the recent change in federal administration in the United States, has added 
additional uncertainty to the implementation, scope and timing of regulatory reforms.

Effect on Economic Environment

The policies of regulatory authorities, including the monetary policy of the Federal Reserve Board, have a 

significant effect on the operating results of bank holding companies and their subsidiaries. Among the means 
available to the Federal Reserve Board to affect the money supply are open market operations in U.S. government 
securities, changes in the discount rate on member bank borrowings and changes in reserve requirements against 
member bank deposits. These means are used in varying combinations to influence overall growth and distribution 
of bank loans, investments and deposits; and their use may affect interest rates charged on loans or paid for deposits.

Federal Reserve Board monetary policies have materially affected the operating results of commercial banks 
in the past and are expected to continue to do so in the future. The nature of future monetary policies and the effect 
of such policies on the business and earnings of the Company and its subsidiaries cannot be predicted.

ITEM  1A. RISK FACTORS

An investment in the Company’s common stock involves risks. The following is a description of the material 

risks and uncertainties that the Company believes affect its business and an investment in the common stock. 
Additional risks and uncertainties that the Company is unaware of, or that it currently deems immaterial, also may 
become important factors that affect the Company and its business. If any of the risks described in this Annual 
Report on Form 10-K were to occur, the Company’s financial condition, results of operations and cash flows could 
be materially and adversely affected. If this were to happen, the value of the common stock could decline 
significantly and all or part of an investment could be lost.

Risks Associated with the Company’s Business

The Company’s business is subject to interest rate risk, and fluctuations in interest rates may adversely affect its 
financial condition and results of operations.

The majority of the Company’s assets are monetary in nature, and, as a result, the Company is subject to 
significant risk from changes in interest rates. Changes in interest rates can impact the Company’s net interest 
income as well as the valuation of its assets and liabilities. The Company’s earnings are significantly dependent on 
its net interest income. Net interest income is the difference between the interest income earned on loans, 
investments and other interest-earning assets and the interest expense paid on deposits, borrowings and other 
interest-bearing liabilities.

Changes in monetary policy, including changes in interest rates, could influence the interest the Company 
receives on loans and securities and the amount of interest it pays on deposits and borrowings, and could also affect 
(1) the Company’s ability to originate loans and obtain deposits, (2) the fair value of the Company’s financial assets 
and liabilities and (3) the average duration of the Company’s mortgage-backed securities portfolio. If the interest 
rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and 
other investments, the Company’s net interest income, and therefore earnings, could be adversely affected. Earnings 
also could be adversely affected if the interest rates received on loans and other investments decrease more quickly 
than the interest rates paid on deposits and other borrowings. Further, the Company’s assets and liabilities may react 
differently to changes in overall market rates or conditions because there may be mismatches between the repricing 
or maturity characteristics of the assets and liabilities. Any substantial, unexpected, prolonged change in market 
interest rates could have a material adverse effect on the Company’s business, financial condition and results of 
operations.

The Company’s business depends on its ability to successfully manage credit risk. 

Our business depends on our ability to successfully measure and manage credit risk. As a lender, we are 

exposed to the risk that the principal of, or interest on, a loan will not be repaid timely or at all or that the value of 
any collateral supporting a loan will be insufficient to cover our outstanding exposure. In addition, we are exposed 
to risks with respect to the period of time over which the loan may be repaid, risks relating to proper loan 
underwriting, risks resulting from changes in economic and industry conditions, and risks inherent in dealing with 

15

individual loans and borrowers. The creditworthiness of a borrower is affected by many factors including local 
market conditions and general economic conditions. If the overall economic climate in the United States, generally, 
or our market areas, specifically, experiences material disruption, our borrowers may experience difficulties in 
repaying their loans, the collateral we hold may decrease in value or become illiquid, and the level of nonperforming 
loans, charge-offs and delinquencies could rise and require significant additional provisions for credit losses. 
Additional factors related to the credit quality of commercial loans include the quality of the management of the 
business and the borrower’s ability both to properly evaluate changes in the supply and demand characteristics 
affecting their market for products and services and to effectively respond to those changes. Additional factors 
related to the credit quality of commercial real estate loans include tenant vacancy rates and the quality of 
management of the property. 

Our risk management practices, such as monitoring the concentration of our loans within specific industries 
and our credit approval, review and administrative practices, may not adequately reduce credit risk, and our credit 
administration personnel, policies and procedures may not adequately adapt to changes in economic or any other 
conditions affecting customers and the quality of the loan portfolio. Many of our loans are made to small and 
medium-sized businesses that are less able to withstand competitive, economic and financial pressures than larger 
borrowers. Consequently, we may have significant exposure if any of these borrowers becomes unable to pay their 
loan obligations as a result of economic or market conditions, or personal circumstances, such as divorce or death. A 
failure to effectively measure and limit the credit risk associated with our loan portfolio may result in loan defaults, 
foreclosures and additional charge-offs, and may necessitate that we significantly increase our allowance for credit 
losses, each of which could adversely affect our net income. As a result, our inability to successfully manage credit 
risk could have a material adverse effect on our business, financial condition and results of operations.

The Company’s allowance for credit losses may not be sufficient to cover actual credit losses, which could 
adversely affect its earnings.

As a lender, the Company is exposed to the risk that its loan customers may not repay their loans according to 

the terms of these loans and the collateral securing the payment of these loans may be insufficient to fully 
compensate the Company for the outstanding balance of the loan plus the costs to dispose of the collateral. The 
Company maintains an allowance for credit losses in an attempt to cover estimated losses inherent in its loan 
portfolio. Additional credit losses will likely occur in the future and may occur at a rate greater than the Company 
has experienced to date. The determination of the appropriate level of the allowance inherently involves a high 
degree of subjectivity and requires the Company to make significant estimates of current credit risks, future trends 
and general economic conditions, all of which may undergo material changes. If the Company’s assumptions prove 
to be incorrect or if it experiences significant credit losses in future periods, its current allowance may not be 
sufficient to cover actual credit losses and adjustments may be necessary to allow for different economic conditions 
or adverse developments in its loan portfolio. A material addition to the allowance could cause net income, and 
possibly capital, to decrease.

In addition, federal and state regulators periodically review the Company’s allowance for credit losses and 

may require the Company to increase its provision for credit losses or recognize further charge-offs, based on 
judgments different than those of the Company’s management. An increase in the Company’s allowance for credit 
losses or charge-offs as required by these regulatory agencies could have a material adverse effect on the Company’s 
operating results and financial condition.

In addition, in June 2016, the Financial Accounting Standards Board issued a new accounting standard that 

will replace the current approach under GAAP for establishing allowances for credit losses, which generally 
considers only past event and current conditions, with a forward-looking methodology that reflects the expected 
credit losses over the lives of financial assets, starting when such assets are first acquired. Under the revised 
methodology, credit losses will be measured based on past events, current conditions and reasonable and supportable 
forecasts that affect the collectability of financial assets. The standard is expected to result in increases to allowance 
levels generally and will require the application of the revised methodology to existing financial assets through a 
one-time adjustment to retained earnings upon initial effectiveness. The standard will be effective for us beginning 
in 2020. See “Notes to Consolidated Financial Statements—Note 1—Summary of Accounting Policies—Pending 
Accounting Pronouncements” for additional information about the standard.

The Company’s profitability depends significantly on local economic conditions.

The Company’s success depends primarily on the general economic conditions of the primary markets in 

Texas and Oklahoma in which it operates and where its loans are concentrated. The local economic conditions in 
Texas and Oklahoma have a significant impact on the Company’s commercial, real estate and construction, land 
development and other land loans; the ability of its borrowers to repay their loans; and the value of the collateral 
securing these loans. Accordingly, if the population or income growth in the Company’s market areas is slower than 
projected, income levels, deposits and housing starts could be adversely affected and could result in a reduction of 
the Company’s expansion, growth and profitability. In addition, due to the large number of oil and gas companies in 
the Company’s market areas, the volatility in oil prices may negatively impact economic conditions in these areas. If 
the Company’s market areas experience a downturn or a recession for a prolonged period of time, the Company 
could experience significant increases in nonperforming loans, which could lead to operating losses, impaired 
liquidity and eroding capital. A significant decline in general economic conditions, caused by inflation, a decline in 
commodity prices, recession, weather extremes, acts of terrorism, outbreaks of hostilities or other international or 
domestic calamities, unemployment or other factors could impact these local economic conditions and could 
negatively affect the Company’s financial condition, results of operations and cash flows.

If the Company is not able to continue its historical levels of growth, it may not be able to maintain its historical 
earnings trends.

To achieve its past levels of growth, the Company has focused on both internal growth and acquisitions. The 

Company may not be able to sustain its historical rate of growth or may not be able to grow at all. More specifically, 
the Company may not be able to obtain the financing necessary to fund additional growth and may not be able to 
find suitable acquisition candidates. Various factors, such as economic conditions, competition and heightened 
regulatory scrutiny, may impede or prohibit the opening of new banking centers and the completion of acquisitions. 
Further, the Company may be unable to attract and retain experienced bankers, which could adversely affect its 
internal growth. If the Company is not able to continue its historical levels of growth, it may not be able to maintain 
its historical earnings trends.

If the Company is unable to manage its growth effectively, its operations and profitability could be negatively 
affected.

The Company faces a variety of risks and difficulties pursuing its growth strategy, including:

finding suitable markets for expansion;

finding suitable candidates for acquisition;

attracting funding to support additional growth;

maintaining asset quality;

attracting and retaining qualified management;

managing execution risks;

maintaining adequate regulatory capital; and 

scaling technology platforms.

In addition, in order to manage its growth and maintain adequate information and reporting systems within its 

organization, the Company must identify, hire and retain additional qualified associates, particularly in the 
accounting and operational areas of its business.

If the Company does not manage its growth effectively, its business, financial condition, results of operations 

and future prospects could be negatively affected, and the Company may not be able to continue to implement its 
business strategy and successfully conduct its operations.

17

If the Company is unable to identify and acquire other financial institutions and successfully integrate its 
acquired businesses, its business and earnings may be negatively affected.

The market for acquisitions remains highly competitive, and the Company may be unable to find acquisition 
candidates in the future that fit its acquisition and growth strategy. To the extent that the Company is unable to find 
suitable acquisition candidates, an important component of its growth strategy may be lost.

Acquisitions of financial institutions involve operational risks and uncertainties and acquired companies may 
have unforeseen liabilities, exposure to asset quality problems, key employee and customer retention problems and 
other problems that could negatively affect the Company’s organization. The Company may not be able to complete 
future acquisitions; and, if completed, the Company may not be able to successfully integrate the operations, 
management, products and services of the entities that it acquires and eliminate redundancies. The integration 
process could result in the loss of key employees or disruption of the combined entity’s ongoing business or 
inconsistencies in standards, controls, procedures and policies that adversely affect the Company’s ability to 
maintain relationships with customers and employees or achieve the anticipated benefits of the transaction. The 
integration process may also require significant time and attention from the Company’s management that they would 
otherwise direct at servicing existing business and developing new business. The Company’s inability to find 
suitable acquisition candidates or failure to successfully integrate the entities it acquires into its existing operations 
may increase its operating costs significantly and adversely affect its business and earnings.

The Company’s dependence on loans secured by real estate subjects it to risks relating to fluctuations in the real 
estate market that could adversely affect its financial condition, results of operations and cash flows.

Approximately 80.5% of the Company’s total loans as of December 31, 2017 consisted of loans included in 

the real estate loan portfolio, with 38.1% in commercial real estate (including farmland and multifamily residential), 
27.3% in residential real estate (including home equity) and 15.1% in construction, land development and other land 
loans. The real estate collateral in each case provides an alternate source of repayment in the event of default by the 
borrower and may deteriorate in value during the time the credit is extended. A weakening of the real estate market 
in the Company’s primary market areas could have an adverse effect on the demand for new loans, the ability of 
borrowers to repay outstanding loans, the value of real estate and other collateral securing the loans and the value of 
real estate owned by the Company. If real estate values decline, it is also more likely that the Company would be 
required to increase its allowance for credit losses, which could adversely affect its financial condition, results of 
operations and cash flows.

The Company’s commercial real estate and commercial loans expose it to increased credit risks, and these risks 
will increase if the Company succeeds in increasing these types of loans.

The Company, while maintaining its conservative approach to lending, has emphasized both new and existing 
loan products, focusing on managing its commercial real estate (including farmland and multifamily residential) and 
commercial loan portfolios, and intends to continue to increase its lending activities and acquire loans in possible 
future acquisitions. As a result, commercial real estate and commercial loans as a proportion of its portfolio could 
increase. As of December 31, 2017, commercial real estate (including farmland and multifamily residential) and 
commercial loans totaled $5.30 billion. In general, commercial real estate loans and commercial loans yield higher 
returns and often generate a deposit relationship, but also pose greater credit risks than do owner-occupied 
residential real estate loans. These types of loans are also typically larger than residential real estate 
loans. Accordingly, the deterioration of one or several of these loans could cause a significant increase in 
nonperforming loans, which could result in a loss of earnings from these loans and an increase in the provision for 
credit losses and net charge-offs.

The Company makes both secured and some unsecured commercial loans. Unsecured loans generally involve 

a higher degree of risk of loss than do secured loans because, without collateral, repayment is wholly dependent 
upon the success of the borrowers’ businesses. Secured commercial loans are generally collateralized by accounts 
receivable, inventory, equipment or other assets owned by the borrower and include a personal guaranty of the 
business owner. Compared to real estate, that type of collateral is more difficult to monitor, its value is harder to 
ascertain, it may depreciate more rapidly and it may not be as readily saleable if repossessed. Further, commercial 
loans generally will be serviced primarily from the operation of the business, which may not be successful, while 

18

commercial real estate loans generally will be serviced from income on the properties securing the loans. As the 
Company’s various commercial loan portfolios increase, the corresponding risks and potential for losses from these 
loans will also increase.

Failure to compete effectively for customers could adversely affect the Company’s growth and profitability, which 
could have a material adverse effect on the Company’s business, financial condition and results of operations.

The Company faces substantial competition in all areas of its operations from a variety of different 

competitors, many of which are larger and may have more financial resources. These competitors primarily include 
national, regional, and community banks within the various markets where the Company operates. The Company 
also faces competition from many other types of financial institutions, including savings and loans, credit unions, 
finance companies, brokerage firms, insurance companies and other financial intermediaries. The financial services 
industry could become even more competitive as a result of legislative, regulatory and technological changes and 
continued consolidation. Also, technology and other changes have lowered barriers to entry and made it possible for 
non-banks to offer products and services functionally equivalent to those provided by banks. The process of 
eliminating banks as intermediaries, known as “disintermediation,” could result in the loss of fee income, as well as 
the loss of customer deposits and the related income generated from those deposits. Further, many of the Company’s 
competitors have fewer regulatory constraints and may have lower cost structures. Additionally, due to their size, 
many competitors may be able to achieve economies of scale and, as a result, may offer a broader range of products 
and services as well as better pricing for those products and services than the Company can.  Failure to compete 
effectively for deposit, loan and other banking customers in the Company’s market areas could adversely affect the 
Company’s growth and profitability, which, in turn, could have a material adverse effect on the Company’s 
business, financial condition and results of operations.

Liquidity risk could impair the Company’s ability to fund operations and jeopardize its financial condition.

Liquidity is essential to the Company’s business. An inability to raise funds through deposits, borrowings, the 

sale of loans and other sources could have a substantial negative effect on its liquidity. The Company’s access to 
funding sources in amounts adequate to finance its activities or on terms which are acceptable to it could be 
impaired by factors that affect the Company specifically or the financial services industry or economy in general. 
Factors that could detrimentally impact the Company’s access to liquidity sources include a decrease in the level of 
its business activity as a result of a downturn in the markets in which its loans are concentrated or adverse regulatory 
action against it. The Company’s ability to borrow could also be impaired by factors that are not specific to it, such 
as a disruption in the financial markets or negative views and expectations about the prospects for the financial 
services industry in light of the recent turmoil faced by banking organizations and the continued deterioration in 
credit markets.

We rely on customer deposits as a significant source of funding, and our deposits may decrease in the future. 

We rely on customer deposits as a significant source of funding. Competition among U.S. banks for customer 

deposits is intense, and may increase the cost of deposits or prevent new deposits, and may otherwise negatively 
affect our ability to grow our deposit base. Our deposit accounts may decrease in the future, and any such decrease 
could have an adverse impact on our sources of funding, which impact could be material. Any changes we make to 
the rates offered on our deposit products to remain competitive with other financial institutions may adversely affect 
our profitability and liquidity. The demand for the deposit products we offer may also be reduced due to a variety of 
factors such as demographic patterns, changes in customer preferences, reductions in consumers’ disposable income, 
regulatory actions that decrease customer access to particular products or the availability of competing products.

If the goodwill that the Company recorded in connection with a business acquisition becomes impaired, it could 
require charges to earnings.

Goodwill represents the amount by which the acquisition cost exceeds the fair value of net assets the 
Company acquired in the purchase of another financial institution. The Company reviews goodwill for impairment 
at least annually, or more frequently if events or changes in circumstances indicate the carrying value of the asset 
might be impaired.

19

The Company determines impairment by comparing the implied fair value of the reporting unit goodwill with 
the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair 
value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Any such adjustments are 
reflected in the Company’s results of operations in the periods in which they become known. At December 31, 2017, 
the Company’s goodwill totaled $1.90 billion. Although the Company has not recorded any such impairment 
charges since it initially recorded the goodwill, the Company’s future evaluations of goodwill could result in 
findings of impairment and related write-downs, which may have a material adverse effect on its financial condition 
and results of operations.

The Company’s accounting estimates and risk management processes rely on analytical and forecasting models 
and tools that may prove to be inaccurate.

The processes the Company uses to estimate its probable credit losses and to measure the fair value of 

financial instruments, as well as the processes used to estimate the effects of changing interest rates and other market 
measures on the Company’s financial condition and results of operations, depend upon the use of analytical and 
forecasting models and tools. These models and tools reflect assumptions that may not be accurate, particularly in 
times of market stress or other unforeseen circumstances. Even if these assumptions are accurate, the models and 
tools may prove to be inadequate or inaccurate because of other flaws in their design or their implementation. Any 
such failure in the Company’s analytical or forecasting models and tools could have a material adverse effect on the 
Company’s business, financial condition and results of operations.

The Company may be adversely affected by the soundness of other financial institutions.

Financial services institutions are interrelated as a result of trading, clearing, counterparty or other 

relationships. The Company has exposure to many different industries and counterparties, and routinely executes 
transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, 
investment banks and other institutional clients. Many of these transactions expose the Company to credit risk in the 
event of a default by a counterparty or client. In addition, the Company’s credit risk may be exacerbated when the 
collateral held by the Company cannot be realized upon or is liquidated at prices not sufficient to recover the full 
amount of the credit or derivative exposure due to the Company. Any such losses could have a material adverse 
effect on the Company’s financial condition, results of operations and cash flows.

The Company may need to raise additional capital in the future and such capital may not be available when 
needed on acceptable terms or at all.

The Company may need to raise additional capital in the future to provide it with sufficient capital resources 

and liquidity to meet regulatory capital requirements or its commitments and business needs. In addition, the 
Company may elect to raise additional capital to support its business or to finance acquisitions, if any. If needed, the 
Company’s ability to raise additional capital will depend on many things, including conditions in the capital markets 
at that time, which are outside its control, and its financial performance.

Such capital may not be available to the Company on acceptable terms or at all. Any occurrence that may limit 

the Company’s access to the capital markets, such as a decline in the confidence of investors, depositors of 
Prosperity Bank or counterparties participating in the capital markets, may adversely affect the Company’s capital 
costs and its ability to raise capital and, in turn, its liquidity. Moreover, if the Company needs to raise capital in the 
future, it may have to do so when many other financial institutions are also seeking to raise capital and would have 
to compete with those institutions for investors. An inability to raise additional capital on acceptable terms when 
needed could have a material adverse effect on the Company’s business, financial condition and results of 
operations.

20

New lines of business or new products and services may subject the Company to additional risks.

From time to time, the Company may implement or acquire new lines of business or offer new products and 
services within existing lines of business. There are substantial risks and uncertainties associated with these efforts, 
particularly in instances where the markets are not fully developed. In developing and marketing new lines of 
business and/or new products and services, the Company may invest significant time and resources. Initial 
timetables for the introduction and development of new lines of business and/or new products or services may not be 
achieved and price and profitability targets may not prove feasible. External factors, such as compliance with 
regulations, competitive alternatives and shifting market preferences, may also impact the successful 
implementation of a new line of business or a new product or service. Furthermore, any new line of business and/or 
new product or service could have a significant impact on the effectiveness of the Company’s system of internal 
controls. Failure to successfully manage these risks in the development and implementation of new lines of business 
or new products or services could have a material adverse effect on the Company’s business, financial condition and 
results of operations.

An interruption in or breach in security of the Company’s information systems may result in a loss of customer 
business and have an adverse effect on the Company’s results of operations, financial condition and cash flows.

The Company relies heavily on communications and information systems to conduct its business. Any failure, 

interruption or breach in security of these systems, whether caused by physical damage, hackers, viruses or other 
malware, could jeopardize the security of information stored in and transmitted through the Company’s computer 
systems and network infrastructure as well as result in failures or disruptions in the Company’s customer 
relationship management, general ledger, deposits, servicing or loan origination systems. While the Company 
maintains specific “cyber” insurance coverage, which the Company expects would apply in the event of various 
breach scenarios, the amount of coverage may not be adequate in any particular case. In addition, cyber threat 
scenarios are inherently difficult to predict and can take many forms, some of which may not be covered under the 
Company’s cyber insurance coverage. Although the Company, with the help of third-party service providers, has 
and intends to continue to implement security technology and operational procedures to prevent such damage, these 
security measures may not entirely mitigate these risks. In addition, advances in computer capabilities, new 
discoveries in the field of cryptography or other developments could result in a compromise or breach of the 
algorithms the Company and its third-party service providers use to protect client transaction data. The occurrence 
of any such failures, interruptions or security breaches could damage the Company’s reputation, result in a loss of 
customer business, subject the Company to additional regulatory scrutiny or expose the Company to civil litigation 
and possible financial liability, any of which could have a material adverse effect on the Company’s results of 
operations, financial condition and cash flows.

The Company is subject to certain risks in connection with its use of technology.

The financial services industry is undergoing rapid technological changes with frequent introductions of new 
technology-driven products and services. The Company’s future success depends in part upon its ability to address 
the needs of its customers by using technology to provide products and services that will satisfy customer demands 
for convenience as well as create additional efficiencies in its operations. Many of the Company’s competitors have 
substantially greater resources to invest in technological improvements. The Company may not be able to effectively 
implement new technology-driven products and services or be successful in marketing these products and services to 
its customers, which may negatively affect the Company’s results of operations, financial condition and cash flows. 
Further, as technology advances, the ability to initiate transactions and access data has become more widely 
distributed among mobile devices, personal computers, automated teller machines, remote deposit capture sites and 
similar access points. These technological advances increase cybersecurity risk. While the Company maintains 
programs intended to prevent or limit the effects of cybersecurity risk, there is no assurance that unauthorized 
transactions or unauthorized access to customer information will not occur. The financial, reputational and 
regulatory impact of unauthorized transactions or unauthorized access to customer information could be significant.

21

The Company’s operations rely on external vendors, which may fail to provide adequate services.

The Company relies on certain external vendors to provide products and services necessary to maintain its 
day-to-day operations. These third parties provide key components of the Company’s business operations such as 
data processing, recording and monitoring transactions, online banking interfaces and services, Internet connections 
and network access. While the Company has selected these third-party vendors carefully, it does not control their 
actions. Any complications caused by these third parties, including those resulting from disruptions in 
communication services provided by a vendor, failure of a vendor to handle current or higher volumes, cyber-attacks 
and security breaches at a vendor, failure of a vendor to provide services for any reason or poor performance of 
services, could adversely affect the Company’s ability to deliver products and services to its customers and 
otherwise conduct its business. Financial or operational difficulties of a third-party vendor could also hurt the 
Company’s operations if those difficulties interfere with the vendor’s ability to provide services. Furthermore, the 
Company’s vendors could also be sources of operational and information security risk, including from breakdowns 
or failures of their own systems or capacity constraints, and reputational risk. Replacing these third-party vendors 
could also create significant delay and expense. Problems caused by external vendors could be disruptive to the 
Company’s operations, which could have a material adverse impact on the Company’s business and, in turn, the 
Company’s financial condition and results of operations.

The Company’s business may be adversely affected by security breaches at third parties.

The Company’s customers interact with their own and other third-party systems, which pose operational risks 

to the Company. The Company may be adversely affected by data breaches at retailers and other third parties who 
maintain data relating to the Company’s customers that involve the theft of customer data, including the theft of 
customers’ debit card, credit card, wire transfer and other identifying and/or access information used to make 
purchases or payments at such retailers and to other third parties. Despite third-party security risks that are beyond 
the Company’s control, the Company offers its customers protection against fraud and attendant losses for 
unauthorized use of debit and credit cards in order to stay competitive in the marketplace. Offering such protection 
to customers exposes the Company to significant expenses and potential losses related to reimbursing the 
Company’s customers for fraud losses, reissuing the compromised cards and increased monitoring for suspicious 
activity. In the event of a data breach at one or more retailers of considerable magnitude, the Company’s business, 
financial condition and results of operations may be adversely affected.

The Company is subject to claims and litigation pertaining to intellectual property.

Banking and other financial services companies, such as the Company, rely on technology companies to 
provide information technology products and services necessary to support their day-to-day operations. Technology 
companies frequently enter into litigation based on allegations of patent infringement or other violations of 
intellectual property rights. In addition, patent holding companies seek to monetize patents they have purchased or 
otherwise obtained. Competitors of the Company’s vendors, or other individuals or companies, have from time to 
time claimed to hold intellectual property sold to the Company by its vendors. Such claims may increase in the 
future as the financial services sector becomes more reliant on information technology vendors. The plaintiffs in 
these actions frequently seek injunctions and substantial damages.

Regardless of the scope or validity of such patents or other intellectual property rights, or the merits of any 
claims by potential or actual litigants, the Company may have to engage in protracted litigation. Such litigation is 
often expensive, time-consuming, disruptive to the Company’s operations and distracting to management. If the 
Company were to be found to have infringed one or more patents or other intellectual property rights, it may be 
required to pay substantial damages or royalties to a third-party. In certain cases, the Company may consider 
entering into licensing agreements for disputed intellectual property, although no assurance can be given that such 
licenses can be obtained on acceptable terms or that litigation will not occur. These licenses may also significantly 
increase the Company’s operating expenses. If legal matters related to intellectual property claims were resolved 
against the Company or settled, the Company could be required to make payments in amounts that could have a 
material adverse effect on its business, financial condition and results of operations.

22

The Company is subject to claims and litigation pertaining to fiduciary responsibility.

From time to time, customers make claims and take legal action pertaining to the Company’s performance of 
its fiduciary responsibilities. Whether customer claims and legal action related to the Company’s performance of its 
fiduciary responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner 
favorable to the Company, they may result in significant financial liability, adversely affect the market perception of 
the Company and its products and services and/or impact customer demand for those products and services. Any 
financial liability or reputation damage could have a material adverse effect on the Company’s business, financial 
condition and results of operations.

The Company operates in a highly regulated environment and, as a result, is subject to extensive regulation and 
supervision.

The Company and the Bank are subject to extensive federal and state regulation and supervision. Banking 
regulations are primarily intended to protect depositors’ funds, federal deposit insurance funds and the banking 
system as a whole, not the Company’s shareholders. These regulations affect the Company’s lending practices, 
capital structure, investment practices, dividend policy and growth, among other things. Congress and federal 
regulatory agencies continually review banking laws, regulations and policies for possible changes. Any change in 
applicable regulations or federal or state legislation could have a substantial impact on the Company, the Bank and 
their respective operations.

The Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial institutions 

regulatory regimes in light of the performance of and government intervention in the financial services sector during 
the several years prior to the implementation of such Act. Additional legislation and regulations or regulatory 
policies, including changes in interpretation or implementation of statutes, regulations or policies, could 
significantly affect the Company’s powers, authority and operations, or the powers, authority and operations of the 
Bank in substantial and unpredictable ways. Further, regulators have significant discretion and power to prevent or 
remedy unsafe or unsound practices or violations of laws by banks and bank holding companies in the performance 
of their supervisory and enforcement duties. The exercise of this regulatory discretion and power could have a 
negative impact on the Company. Failure to comply with laws, regulations or policies could result in sanctions by 
regulatory agencies, civil money penalties and/or reputation damage, which could have a material adverse effect on 
the Company’s business, financial condition and results of operations.

The Company’s risk management framework may not be effective in identifying, managing or mitigating risks 
and/or losses to it.

The Company has implemented a risk management framework to identify and manage its risk exposure, 
which is reviewed and overseen by the Company’s Risk Committee. This framework consists of various processes, 
systems and strategies, and is designed to manage the types of risk to which the Company is subject, including, 
among others, credit, market, liquidity, operational, financial, interest rate, legal and regulatory, compliance, 
strategic, reputation, fiduciary and general economic risks. The Company’s framework also includes financial or 
other modeling methodologies, which involves management assumptions and judgment. In addition, under this 
framework, the Company has developed a risk appetite statement to detail its risk tolerance levels at an enterprise-
wide level. This risk management framework may not be effective under all circumstances, and it may not 
adequately identify, manage or mitigate all or any risk or loss to the Company. If this framework is not effective, the 
Company may be subject to potentially adverse regulatory consequences and could suffer unexpected losses and its 
financial condition or results of operations could be materially adversely affected.

The Company is subject to losses resulting from fraudulent and negligent acts on the part of loan applicants, 
correspondents or other third parties.

The Company relies heavily upon information supplied by third parties, including the information contained 
in credit applications, property appraisals, title information, equipment pricing and valuation and employment and 
income documentation, in deciding which loans the Company will originate, as well as the terms of those loans. If 
any of the information upon which the Company relies is misrepresented, either fraudulently or inadvertently, and 
the misrepresentation is not detected prior to asset funding, the value of the asset may be significantly lower than 

23

expected, or the Company may fund a loan that it would not have funded or on terms it would not have extended. 
Whether a misrepresentation is made by the applicant or another third party, the Company generally bears the risk of 
loss associated with the misrepresentation. A loan subject to a material misrepresentation is typically unsellable or 
subject to repurchase if it is sold prior to detection of the misrepresentation. The sources of the misrepresentations 
are often difficult to locate, and it is often difficult to recover any of the monetary losses the Company may suffer.

The Company is subject to environmental liability risk associated with lending activities.

A significant portion of the Company’s loan portfolio is secured by real property. During the ordinary course 
of business, the Company may foreclose on and take title to properties securing certain loans, and there is a risk that 
hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, the 
Company may be liable for remediation costs, as well as for personal injury and property damage. Environmental 
laws may require the Company to incur substantial expenses and may materially reduce the affected property’s 
value or limit the Company’s ability to use or sell the affected property. In addition, future laws or more stringent 
interpretations or enforcement policies with respect to existing laws may increase the Company’s exposure to 
environmental liability. Although the Company has policies and procedures to perform an environmental review 
before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential 
environmental hazards. The remediation costs and any other financial liabilities associated with an environmental 
hazard could have a material adverse effect on the Company’s financial condition and results of operations.

Risks Associated with the Company’s Common Stock

The Company’s corporate organizational documents and the provisions of Texas law to which it is subject may 
delay or prevent a change in control of the Company that a shareholder may favor.

The Company’s amended and restated articles of incorporation and amended and restated bylaws contain 
various provisions which may delay, discourage or prevent an attempted acquisition or change of control of the 
Company. These provisions include:

(cid:129)

(cid:129)

(cid:129)

a Board of Directors classified into three classes of directors with the directors of each class having 
staggered three-year terms;

a provision that any special meeting of the Company’s shareholders may be called only by the chairman 
of the board and chief executive officer, the president, a majority of the Board of Directors or the 
holders of at least 50% of the Company’s shares entitled to vote at the meeting; and

a provision establishing certain advance notice procedures for nomination of candidates for election as 
directors and for shareholder proposals to be considered at an annual or special meeting of shareholders.

The Company’s articles of incorporation provide for noncumulative voting for directors and authorize the 
Board of Directors to issue shares of its preferred stock without shareholder approval and upon such terms as the 
Board of Directors may determine. The issuance of the Company’s preferred stock could have the effect of making 
it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a controlling interest in 
the Company. In addition, certain provisions of Texas law, including a provision which restricts certain business 
combinations between a Texas corporation and certain affiliated shareholders, may delay, discourage or prevent an 
attempted acquisition or change in control of the Company.

There are restrictions on the Company’s ability to pay dividends.

Holders of the Company’s common stock are only entitled to receive such dividends as the Company’s Board 

of Directors may declare out of funds legally available for such payments. Although the Company has historically 
declared cash dividends on its common stock, it is not required to do so and there can be no assurance that the 
Company will pay dividends in the future. Any declaration and payment of dividends on common stock will depend 
upon the Company’s earnings and financial condition, liquidity and capital requirements, the general economic and 
regulatory climate, the Company’s ability to service any equity or debt obligations senior to the common stock and 
other factors deemed relevant by the Board of Directors.

24

The Company’s principal source of funds to pay dividends on the shares of common stock is cash dividends 

that the Company receives from the Bank. Various banking laws applicable to the Bank limit the payment of 
dividends and other distributions by the Bank to the Company, and may therefore limit the Company’s ability to pay 
dividends on its common stock.

There may be extreme fluctuations in the Company’s stock price.

The trading price for the Company’s common stock may fluctuate significantly in response to a variety of 

factors outside our control, including, among other things:

Dividends

Holders of common stock are entitled to receive dividends when, as and if declared by the Company’s Board 
of Directors out of funds legally available therefor. Although the Company has declared dividends on its common 
stock since 1994, and paid quarterly dividends aggregating $1.38 per share for 2017 and $1.24 per share for 2016, 
the Company could discontinue payment of dividends in the future. Future dividends on the common stock will 
depend upon the Company’s earnings and financial condition, liquidity and capital requirements, the general 
economic and regulatory climate, the Company’s ability to service any equity or debt obligations senior to the 
common stock and other factors deemed relevant by the Board of Directors of the Company.

As a holding company, the Company is ultimately dependent upon its subsidiaries to provide funding for its 
operating expenses, debt service and dividends. Various banking laws applicable to the Bank limit the payment of 
dividends and other distributions by the Bank to the Company, and may therefore limit the Company’s ability to pay 
dividends on its common stock. Regulatory authorities could impose administratively stricter limitations on the 
ability of the Bank to pay dividends to the Company if such limits were deemed appropriate to preserve certain 
capital adequacy requirements.

In addition, the Federal Reserve Board has indicated that bank holding companies should carefully review 

their dividend policy in relation to the organization’s overall asset quality, level of current and prospective earnings 
and level, composition and quality of capital. The guidance provides that the Company should inform and consult 
with the Federal Reserve Board prior to declaring and paying a dividend that exceeds earnings for the period for 
which the dividend is being paid or that could result in an adverse change to the Company’s capital structure.

Management’s Discussion and Analysis of Financial Condition and Results of Operations analyzes the major 

elements of the Company’s balance sheets and statements of income. This section should be read in conjunction 
with the Company’s consolidated financial statements and accompanying notes and other detailed information 
appearing elsewhere in this Annual Report on Form 10-K.

Overview

The Company generates the majority of its revenues from interest income on loans, service charges and fees 

on customer accounts and income from investment in securities. The Company also earns revenues from various 
additional products and services it provides, including trust services, mortgage lending, brokerage, credit card and 
independent sales organization sponsorship operations. The Company’s revenues are partially offset by interest 
expense paid on deposits and other borrowings and noninterest expenses such as administrative and occupancy 
expenses. Net interest income is the difference between interest income on earning assets such as loans and 
securities and interest expense on liabilities such as deposits and borrowings which are used to fund those assets. Net 
interest income is the Company’s largest source of revenue. The level of interest rates and the volume and mix of 
earning assets and interest-bearing liabilities impact net interest income and margin.

Three principal components of the Company’s growth strategy are internal growth, efficient operations and 

acquisitions, including strategic merger transactions. The Company focuses on continual internal growth. Each 
banking center is operated as a separate profit center, maintaining separate data with respect to its net interest 
income, efficiency ratio, deposit growth, loan growth and overall profitability. Banking center presidents and 
managers are accountable for performance in these areas and compensated accordingly. The Company also focuses 
on maintaining efficiency and stringent cost control practices and policies. The Company has centralized many of its 
critical operations, such as data processing and loan processing. Management believes that this centralized 

33

infrastructure can accommodate substantial additional growth while enabling the Company to minimize operational 
costs through certain economies of scale. The Company also intends to continue to seek expansion opportunities. 
During 2016, the Company completed the acquisition of Tradition Bancshares, Inc., which added 7 banking centers 
after consolidation. 

Net income was $272.2 million, $274.5 million and $286.6 million for the years ended December 31, 2017, 

2016 and 2015, respectively, and diluted earnings per share were $3.92, $3.94 and $4.09, respectively, for these 
same periods. The change in net income during 2017 was principally due to an increase in interest expense and a 
decrease in loan discount accretion. The change in net income during 2016 was principally due to an increase in the 
provision for credit losses and the Tradition acquisition. The Company posted returns on average assets of 1.22%, 
1.25% and 1.33% and returns on average common equity of 7.26%, 7.69% and 8.51% for the years ended 
December 31, 2017, 2016 and 2015, respectively. The Company’s efficiency ratio was 42.76% in 2017, 42.50% in 
2016 and 41.87% in 2015. The efficiency ratio is calculated by dividing total noninterest expense (excluding credit 
loss provisions) by the sum of net interest income and noninterest income. Because the ratio is a measure of 
revenues and expenses resulting from our lending activities and fee-based banking services, net gains and losses on 
the sale of assets and securities are not included. Additionally, taxes are not part of this calculation.

Total assets at December 31, 2017 and 2016 were $22.59 billion and $22.33 billion, respectively. Total 
deposits were $17.82 billion at December 31, 2017, an increase of $514.2 million or 3.0% compared with $17.31 
billion at December 31, 2016. Total loans were $10.02 billion at December 31, 2017, an increase of $398.7 million 
or 4.1% compared with $9.62 billion at December 31, 2016. At December 31, 2017, the Company had $26.3 million 
in nonperforming loans, and its allowance for credit losses was $84.0 million compared with $32.6 million in 
nonperforming loans and an allowance for credit losses of $85.3 million at December 31, 2016. Shareholders’ equity 
was $3.82 billion and $3.64 billion at December 31, 2017 and 2016, respectively.

Acquisition

Acquisition of Tradition Bancshares, Inc.—On January 1, 2016, the Company completed the acquisition of 

Tradition Bancshares, Inc. (“Tradition”) and its wholly-owned subsidiary Tradition Bank headquartered in Houston, 
Texas. Tradition Bank operated 7 banking offices in the Houston, Texas area, including its main office in Bellaire, 3 
banking centers in Katy and 1 banking center in The Woodlands.

As of December 31, 2015, Tradition, on a consolidated basis, reported total assets of $548.0 million, total 

loans of $253.3 million, total deposits of $488.9 million and shareholders’ equity of $43.1 million. Under the terms 
of the definitive agreement, the Company issued 679,528 shares of its common stock plus $39.0 million in cash for 
all outstanding shares of Tradition capital stock, for total merger consideration of $71.5 million, based on the 
Company’s closing stock price of $47.86. As of December 31, 2017, the Company recognized goodwill of $32.0 
million, which is calculated as the excess of both the consideration exchanged and liabilities assumed compared with 
the fair value of the assets acquired. Additionally, the Company recognized $5.6 million of core deposit intangibles 
during 2016. 

On January 1, 2016, in connection with the acquisition of Tradition, the Company assumed $7.2 million in 

junior subordinated debentures. During the second quarter of 2016, the Company redeemed all of the junior 
subordinated debentures. Accordingly, as of December 31, 2016 and 2017, the Company had no junior subordinated 
debentures outstanding.

Critical Accounting Policies

The Company’s significant accounting policies are integral to understanding the results reported. The 
Company’s accounting policies are described in detail in Note 1 to the consolidated financial statements, appearing 
elsewhere is this Annual Report on Form 10-K. The Company believes that of its significant accounting policies, the 
following may involve a higher degree of judgment and complexity:

Allowance for Credit Losses—The allowance for credit losses is established through charges to earnings in the 

form of a provision for credit losses. The Company’s allowance for credit losses consists of two elements: 
(1) specific valuation allowances based on probable losses on impaired loans; and (2) a general valuation allowance 
based on historical loan loss experience, general economic conditions and other qualitative risk factors both internal 
and external to the Company. The allowance for acquired credit losses is calculated as described under the heading 
“Accounting for Acquired Loans and the Allowance for Acquired Credit Losses” below. Management has 
established an allowance for credit losses which it believes is adequate for estimated losses in the Company’s loan 
portfolio. Based on an evaluation of the portfolio, management presents a quarterly review of the allowance for 
credit losses to the Bank’s Board of Directors, indicating any change in the allowance since the last review and any 
recommendations as to adjustments in the allowance. In making its evaluation, management considers factors such 
as historical loan loss experience, the amount of nonperforming assets and related collateral, the volume, growth and 
composition of the portfolio, current economic conditions that may affect the borrower’s ability to pay and the value 
of collateral, the evaluation of the portfolio through its internal loan review process and other relevant factors. 
Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any 
credit that, in management’s judgment, should be charged off. Charge-offs occur when loans are deemed to be 
uncollectible. For further discussion of the methodology used in the determination of the allowance for credit losses, 
see “Financial Condition—Allowance for Credit Losses” below and Note 1 to the consolidated financial statements.

Accounting for Acquired Loans and the Allowance for Acquired Credit Losses—The Company accounts for its 

acquisitions using the acquisition method of accounting. Accordingly, the assets, including loans, and liabilities of 
the acquired entity were recorded at their fair values at the acquisition date. No allowance for credit losses related to 
the acquired loans is recorded on the acquisition date, as the fair value of the acquired loans incorporates 
assumptions regarding credit risk. These fair value estimates associated with acquired loans, and based on a 
discounted cash flow model, include estimates related to market interest rates and undiscounted projections of future 
cash flows that incorporate expectations of prepayments and the amount and timing of principal, interest and other 
cash flows, as well as any shortfalls thereof.

At period-end after acquisition, the fair-valued acquired loans from each acquisition are reassessed to 
determine whether an addition to the allowance for credit losses is appropriate due to further credit quality 
deterioration. For further discussion of the methodology used in the determination of the allowance for credit losses 
for acquired loans, see “Financial Condition—Allowance for Credit Losses” below. For further discussion of the 
Company’s acquisition and loan accounting, see Note 1 to the consolidated financial statements.

Goodwill and Intangible Assets—Goodwill and intangible assets that have indefinite useful lives are subject to 
an impairment test at least annually, or more often, if events or circumstances indicate that it is more likely than not 
that the fair value of the Company’s reporting unit is below the carrying value of its equity. Under Accounting 
Standards Codification (“ASC”) topic 350-20, “Intangibles—Goodwill and Other—Goodwill,” companies have the 
option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a 
reporting unit is less than its carrying amount as a basis for determining the need to perform step one of the annual 
test for goodwill impairment. An entity has an unconditional option to bypass the qualitative assessment described in 
the preceding paragraph for any reporting unit in any period and proceed directly to performing the first step of the 
goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. 
The Company currently utilizes a qualitative assessment for its annual goodwill impairment analysis.

If the Company bypasses the qualitative assessment, a two-step goodwill impairment test is performed. The 

two-step process begins with an estimation of the fair value of the Company’s reporting unit compared with its 
carrying value. If the carrying amount exceeds the fair value of the reporting unit, a second test is completed 
comparing the implied fair value of the reporting unit’s goodwill to its carrying value to measure the amount of 
impairment.

35

The Company had no intangible assets with indefinite useful lives at December 31, 2017. Core deposit 
intangible assets that are subject to amortization are being amortized on a non-pro rata basis over the years expected 
to be benefited, which the Company believes is between ten and fifteen years. These core deposit intangible assets 
are reviewed for impairment if circumstances indicate their value may not be recoverable based on a comparison of 
fair value to carrying value. Based on the Company’s annual goodwill impairment test as of September 30, 2017, 
management does not believe any of its goodwill is impaired as of December 31, 2017, because the fair value of the 
Company’s equity exceeded its carrying value. While the Company believes no impairment existed at December 31, 
2017, under accounting standards applicable at that date, different conditions or assumptions, or changes in cash 
flows or profitability, if significantly negative or unfavorable, could have a material adverse effect on the outcome 
of the Company’s impairment evaluation and financial condition or future results of operations.

Stock-Based Compensation—The Company accounts for stock-based employee compensation plans using the 

fair value-based method of accounting. The Company’s results of operations reflect compensation expense for all 
employee stock-based-compensation. The fair value of stock options granted is estimated at the date of grant using 
the Black-Scholes option-pricing model. This model requires the input of subjective assumptions including stock 
price volatility and employee turnover that are utilized to measure compensation expense.

Other-Than-Temporarily Impaired Securities—When the fair value of a security is below its amortized cost, 

and depending on the length of time the condition exists and the extent the fair market value is below amortized 
cost, additional analysis is performed to determine whether an other-than-temporary impairment exists. Available 
for sale and held to maturity securities are analyzed quarterly for possible other-than-temporary impairment. The 
analysis considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the 
financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by 
macroeconomic conditions and (4) whether the entity has the intent to sell the debt security or more likely than not 
will be required to sell the debt security before its anticipated recovery. Often, the information available to conduct 
these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual 
information or conditions are different than estimated, the extent of the impairment of the security may be different 
than previously estimated, which could have a material effect on the Company’s results of operations and financial 
condition.

Fair Values of Financial Instruments—The Company determines the fair market values of financial 

instruments based on the fair value hierarchy established which requires an entity to maximize the use of observable 
inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that 
may be used to measure fair value. Level 1 inputs include quoted market prices, where available. If such quoted 
market prices are not available, Level 2 inputs are used. These inputs are based upon internally developed analytical 
tools that primarily use observable, market-based parameters. Level 3 inputs are unobservable inputs which are 
typically based on an entity’s own assumptions, as there is little, if any, related market activity. The Company’s 
assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment 
and considers factors specific to the asset or liability.

Hurricane Harvey

On August 25, 2017, Hurricane Harvey came ashore in Rockport, Texas impacting numerous communities 
along the Texas Gulf coast. Prosperity Bank operates 94 banking centers in the Houston and South Texas areas, 
which include Beaumont, Corpus Christi and Victoria. All of those banking centers are currently operational, 
including three currently using a temporary facility. As of December 31, 2017, the Company has not experienced 
any material financial impact related to Hurricane Harvey. 

Tax Cuts and Jobs Act

The Tax Cuts and Jobs Act was enacted on December 22, 2017 and made widespread changes to the U.S. tax 

code effective January 1, 2018. Under ASC Topic 740 “Income Taxes,” the Company was required to recalculate its 
deferred tax assets and liabilities to account for the future impact of lower corporate tax rates and lost deductions on 
these assets and liabilities. The recalculation resulted in a one-time non-cash charge of $1.4 million recorded to 
income tax expense for the year ended December 31, 2017. 

36

Results of Operations

Net Interest Income

The Company’s operating results depend primarily on its net interest income, which is the difference between 

interest income on interest-earning assets, including securities and loans, and interest expense incurred on interest-
bearing liabilities, including deposits and other borrowed funds. Interest rate fluctuations, as well as changes in the 
amount and type of earning assets and liabilities, combine to affect net interest income. The Company’s net interest 
income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, 
referred to as a “volume change.” It is also affected by changes in yields earned on interest-earning assets and rates 
paid on interest-bearing deposits and other borrowed funds, referred to as a “rate change.”

2017 versus 2016. Net interest income before the provision for credit losses for 2017 was $616.9 million 

compared with $632.6 million for 2016, a decrease of $15.8 million or 2.5%. The decrease in net interest income 
was primarily due to a decrease in loan discount accretion of $17.1 million and a 13-basis-point increase in the 
average rate on interest-bearing liabilities, partially offset by an increase in average interest-earning assets of $474.1 
million or 2.5%. Interest income was $677.4 million in 2017, an increase of $1.6 million or 0.2% compared with 
2016. Interest income on loans was $468.3 million for 2017, a decrease of $6.7 million or 1.4% compared with 
2016. This was primarily due to a decrease in loan discount accretion of $17.1 million, partially offset by an increase 
in average loans of $192.5 million or 2.0%. The Company had $34.7 million of total outstanding discounts on 
purchased loans, of which $28.7 million was accretable at December 31, 2017. Interest income on securities was 
$208.2 million during 2017, an increase of $7.8 million or 3.9% compared with 2016 due primarily to an increase in 
average securities of $280.1 million or 3.0%. Average interest-bearing liabilities increased $62.8 million or 0.5% 
during 2017 compared with 2016. The average rate on interest-bearing liabilities increased from 0.33% to 0.46% 
during the same time period, resulting in an increase in interest expense of $17.3 million. The total cost of funds 
increased to 0.33% during 2017 from 0.24% during 2016. 

Net interest margin, defined as net interest income divided by average interest-earning assets, on a tax 

equivalent basis, was 3.19% for 2017, a decrease of 16 basis points compared with 3.35% for 2016.

2016 versus 2015. Net interest income before the provision for credit losses for 2016 was $632.6 million 
compared with $630.5 million for 2015, an increase of $2.1 million or 0.3%. The increase in net interest income was 
primarily due to an increase in average interest-earning assets of $254.7 million or 1.4%, partially offset by a 
decrease in purchase accounting loan discount accretion of $13.2 million and a 3-basis-point increase in the average 
rate paid on interest-bearing liabilities. Interest income was $675.8 million in 2016, an increase of $6.1 million or 
0.9% compared with 2015. Interest income on loans was $475.1 million for 2016, a decrease of $368 thousand or 
0.1% compared with 2015. This was primarily due to a decrease in purchase accounting loan discount accretion of 
$13.2 million and a 24-basis-point decrease in the average yield earned on loans, partially offset by an increase in 
average loans outstanding of $428.9 million. The Company had $59.4 million of total outstanding discounts on 
purchased loans, of which $45.2 million was accretable at December 31, 2016. Interest income on securities was 
$200.4 million during 2016, an increase of $6.4 million or 3.3% compared with 2015 due primarily to a 10-basis-
point increase in the average yield on investment securities, partially offset by a decrease in average investment 
securities outstanding of $139.8 million. Average interest-bearing liabilities decreased $39.2 million or 0.3% for 
2016 compared with 2015. The average rate paid increased from 0.30% to 0.33% for the same time period, resulting 
in an overall increase in interest expense of $4.0 million. The increase in the average rate paid on interest-bearing 
liabilities contributed to an increase in total cost of funds to 0.24% during 2016 from 0.22% during 2015. 

Net interest margin, on a tax equivalent basis, was 3.35% for 2016, a decrease of 3 basis points compared with 

3.38% for 2015.

(1) The net interest margin is equal to net interest income divided by average interest-earning assets.
(2) In order to make pretax income and resultant yields on tax-exempt investments and loans comparable to those on 
taxable investments and loans, a tax equivalent adjustment has been computed using a federal income tax rate of 
35% for the years ended December 31, 2017, 2016 and 2015 and other applicable effective tax rates.

The Company’s provision for credit losses is established through charges to income in the form of the 
provision in order to bring the Company’s allowance for credit losses to a level deemed appropriate by management 
based on the factors discussed under “Financial Condition—Allowance for Credit Losses.” The allowance for credit 
losses at December 31, 2017 was $84.0 million, representing 0.84% of total loans as of such date. Acquired loans 
were recorded at fair value based on a discounted cash flow valuation methodology that considers, among other 
things, interest rates, projected default rates, loss given defaults and recovery rates, with no carryover of any existing 
allowance for credit losses. The provision for credit losses for the year ended December 31, 2017 was $14.3 million 
compared with $24.0 million for the year ended December 31, 2016 and $7.6 million for the year ended 
December 31, 2015. Net charge-offs for the years ended December 31, 2017, 2016 and 2015 were $15.6 million, 
$20.1 million and $6.9 million, respectively.

Noninterest Income

The Company’s primary sources of recurring noninterest income are nonsufficient funds (“NSF”) fees, credit, 

debit and ATM card income, and service charges on deposit accounts. Additionally, the Company generates 
recurring noninterest income from its various additional products and services, including trust services, mortgage 
lending, brokerage and independent sales organization sponsorship operations. Noninterest income does not include 
loan origination fees which are recognized over the life of the related loan as an adjustment to yield using the 
interest method. For the year ended December 31, 2017, noninterest income totaled $116.6 million, a decrease of 
$1.8 million or 1.5% compared with 2016. The decrease was primarily due to the net loss on sale of assets and 
decreases in mortgage and brokerage income, partially offset by a gain on sale of securities and an increase in 
service charges on deposit accounts.

income and NSF fees, partially offset by an increase in service charges on deposit accounts and mortgage income.

 Noninterest Expense

For the year ended December 31, 2017, noninterest expense totaled $313.1 million, a decrease of $5.3 million 
or 1.7% compared with 2016. This decrease was primarily due to decreases in salaries and benefits and amortization 
of core deposit intangibles, partially offset by the write-down of other real estate. 

For the year ended December 31, 2016, noninterest expense totaled $318.4 million, an increase of $4.9 million 

or 1.5% compared with 2015. This increase was primarily due to the Tradition acquisition.

Salaries and Employee Benefits. Salaries and employee benefits were $192.4 million for the year ended 

December 31, 2017, a decrease of $5.5 million or 2.8% compared with 2016. This change was primarily due to a 
decrease in stock based compensation expense and commissions. Salaries and employee benefits were $197.9 
million for the year ended December 31, 2016, an increase of $5.0 million or 2.6% compared with 2015. This 
change was primarily due to the Tradition acquisition and an increase in incentive compensation. The number of 
full-time equivalent associates employed by the Company were 3,017, 3,035 and 3,037 at December 31, 2017, 2016 
and 2015, respectively. Total salaries and benefits for the year ended December 31, 2017 include $6.9 million in 
stock-based compensation expense compared with $9.5 million and $11.1 million recorded for the years ended 
December 31, 2016 and 2015, respectively. 

Credit and Debit Card, Data Processing and Software Amortization. Credit and Debit card, data processing 
and software amortization expenses were $17.2 million for the year ended December 31, 2017, an increase of $180 
thousand or 1.1% compared with 2016. Credit and Debit card, data processing and software amortization expenses 
were $17.1 million and $15.8 million for the years ended December 31, 2016 and 2015, respectively. 

Regulatory Assessments and FDIC Insurance. Regulatory assessments and FDIC insurance assessments were 

$14.3 million for the year ended December 31, 2017, an increase of $1.6 million or 12.4%, compared with $12.7 
million for the year ended December 31, 2016. Assessments for the year ended December 31, 2016 decreased $1.7 
million or 11.8% to $12.7 million compared with $14.4 million for the year ended December 31, 2015. 

Core Deposit Intangibles Amortization. Core deposit intangibles (“CDI”) amortization was $6.9 million for 

the year ended December 31, 2017, a decrease of $2.3 million or 24.5% compared with $9.2 million for the year 
ended December 31, 2016. This change was primarily due to certain intangible assets that fully amortized during 
2017. CDI amortization decreased $330 thousand or 3.5% to $9.2 million at December 31, 2016, compared with 
$9.5 million for the year ended December 31, 2015. This change was primarily due to a reduction in the annual 
amortization rate of certain previously recognized intangible assets. CDI are being amortized on a non-pro rata basis 
over an estimated life of 10 to 15 years.

Other Real Estate. Other real estate expense was $3.3 million for the year ended December 31, 2017, an 
increase of $2.8 million or 536.4%, compared with $514 thousand for the year ended December 31, 2016. This 
change was primarily due to the write-down of other real estate. Other real estate expense decreased $111 thousand 
or 17.8% to $514 thousand for the year ended December 31, 2016, compared with $625 thousand for the year ended 
December 31, 2015. This change was primarily due to a decrease in other real estate carrying cost. 

Efficiency Ratio

The Company’s efficiency ratio is a supplemental financial measure utilized in management’s internal 
evaluation of the Company and is not calculated based on generally accepted accounting principles (“GAAP”). A 
GAAP-based efficiency ratio is calculated by dividing total noninterest expense, excluding credit loss provisions, by 
net interest income plus total noninterest income, as shown in the Consolidated Statements of Income. The 
Company’s efficiency ratio, as calculated and used by the Company, excludes from noninterest income the net gains 
and losses on the sale of securities and assets, which can vary widely from period to period.  Taxes are not included 
in either calculation. An increase in the efficiency ratio indicates that more resources are being utilized to generate 
the same volume of income, while a decrease would indicate a more efficient allocation of resources. The 
Company’s efficiency ratio calculated pursuant to GAAP was 42.69% for the year ended December 31, 2017 
compared with 42.39% for the year ended December 31, 2016 and 41.73% for the year ended December 31, 2015. 
The efficiency ratio, excluding net gains and losses on the sale of securities and assets, was 42.76% for the year 
ended December 31, 2017, compared with 42.50% for the year ended December 31, 2016 and 41.87% for the year 
ended December 31, 2015.

Income Taxes

The amount of federal and state income tax expense is influenced by the amount of pre-tax income, the 
amount of tax-exempt income and the amount of other nondeductible expenses. As a result of the Tax Cuts and Jobs 
Act enacted in December 2017, the Company recorded a one-time non-cash charge of $1.4 million to income tax 
expense to account for the future impact of lower corporate tax rates and lost deductions on deferred tax assets and 
liabilities. 

Income tax expense was $133.9 million for the year ended December 31, 2017, a decrease of $287 thousand 

or 0.2% compared with $134.2 million for the year ended December 31, 2016. The decrease was primarily 
attributable to lower pre-tax net earnings, partially offset by the one-time non-cash charge related to the Tax Cuts 
and Jobs Act. Income tax expense decreased $9.4 million or 6.5% for the year ended December 31, 2016, compared 
with $143.5 million for the year ended December 31, 2015. The decrease was primarily attributable to lower pre-tax 
net earnings for the year ended December 31, 2016. The effective tax rate for the years ended December 31, 2017, 
2016 and 2015 was 33.0%, 32.8% and 33.4%, respectively. The effective income tax rates differed from the U.S. 
statutory rate of 35% during the comparable periods primarily due to the effect of tax-exempt income from loans 
and securities.

Impact of Inflation

The Company’s consolidated financial statements and related notes included in this Annual Report on 
Form 10-K have been prepared in accordance with GAAP. These require the measurement of financial position and 
operating results in terms of historical dollars, without considering changes in the relative value of money over time 
due to inflation or recession.

Unlike many industrial companies, substantially all of the Company’s assets and liabilities are monetary in 

nature. As a result, interest rates have a more significant impact on the Company’s performance than the effects of 
general levels of inflation. Interest rates may not necessarily move in the same direction or in the same magnitude as 
the prices of goods and services. However, noninterest expenses do reflect general levels of inflation.

The Company separates its loan portfolio into two general categories of loans: (1) loans originated by 
Prosperity Bank and made pursuant to the Company’s loan policy and procedures in effect at the time the loan was 
made are referred to as “legacy loans” and (2) “acquired loans,” which are loans acquired in a business combination. 
Those acquired loans that are renewed or substantially modified after the date of the business combination, thereby 
subjecting them to the Company’s allowance for credit losses methodology, are referred to as “acquired legacy 
loans.” If a renewal or substantial modification of an acquired loan is underwritten by the Company with a new 
credit analysis, the loan will no longer be categorized as an acquired loan. For example, acquired loans to one 
borrower may be combined into a new loan with a new loan number and categorized as a legacy loan. Acquired 
loans with a fair value discount or premium at the date of the business combination that remained at the reporting 
date are referred to as “fair-valued acquired loans.” All fair-valued acquired loans are further categorized into “Non-
PCI loans” and “PCI loans” (purchased credit impaired loans). Acquired loans with evidence of credit quality 
deterioration at acquisition for which it is probable that the Company would not be able to collect all contractual 
amounts due are PCI loans.

The Company offers a broad range of short to medium-term commercial loans, primarily collateralized, to 

businesses for working capital (including inventory and receivables), business expansion (including acquisitions of 
real estate and improvements) and the purchase of equipment and machinery. Historically, the Company has 
originated loans for its own account, including all loans in the 1-4 family residential category, and has not 
securitized its loans. However, the Company does originate longer-term residential mortgage loans for sale into the 
secondary market. The purpose of a particular loan generally determines its structure.

Loans to borrowers with aggregate debt relationships over $1.0 million and below $3.5 million are evaluated 

and acted upon on a daily basis by two of the company-wide loan concurrence officers. Loans to borrowers with 
aggregate debt relationships above $3.5 million are evaluated and acted upon by an officers’ loan committee that 
meets weekly. In addition to the officers’ loan committee evaluation, loans to borrowers with aggregate debt 
relationships from $25.0 million to $50.0 million are evaluated and acted upon by the directors’ loan committee 
which consists of three directors of the Bank and meets as necessary. Loans to borrowers with aggregate debt 
relationships over $50.0 million are evaluated and acted upon by the Bank’s Board of Directors either at a regularly 
scheduled monthly board meeting or by teleconference or written consent.

Commercial and Industrial Loans. In nearly all cases, the Company’s commercial loans are made in the 
Company’s market areas and are underwritten on the basis of the borrower’s ability to service the debt from income. 
As a general practice, the Company takes as collateral a lien on any available real estate, equipment or other assets 
owned by the borrower and obtains a personal guaranty of the borrower or principal. Working capital loans are 
primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets. In 
general, commercial loans involve more credit risk than residential mortgage loans and commercial mortgage loans 
and, therefore, usually yield a higher return. The increased risk in commercial loans is due to the type of collateral 
securing these loans as well as the expectation that commercial loans generally will be serviced principally from the 
operations of the business, and those operations may not be successful. Historical trends have shown these types of 
loans to have higher delinquencies than mortgage loans. As a result of these additional complexities, variables and 
risks, commercial loans require more thorough underwriting and servicing than other types of loans.

Included in commercial loans are (1) commitments to oil and gas producers secured by proven, developed and 

producing reserves and (2) commitments to service, equipment and midstream companies secured mainly by 
accounts receivable, inventory and equipment. Mineral reserve values supporting commitments to producers are 
normally re-determined semi-annually using reserve studies prepared by a third-party or the Company’s oil and gas 
engineer. Accounts receivable and inventory borrowing bases for service companies are typically re-determined 
monthly. Funding requests by both producers and service companies are monitored relative to the most recently 
determined borrowing base. As of December 31, 2017, the Company had $112.2 million in funded commitments 
outstanding to oil and gas production companies and $63.0 million in unfunded commitments, for a total of $175.2 
million. This compares with funded commitments to production companies of $119.9 million as of December 31, 
2016 and $72.1 million in unfunded commitments, for a total of $192.0 million. Total unfunded commitments to 
producers include letters of credit issued in lieu of oil well plugging bonds. As of December 31, 2017, the Company 
had outstanding $188.3 million in funded commitments to service companies and $90.6 million in unfunded 
commitments for a total of $278.9 million. This compares with funded commitments to service companies of $164.6 
million as of December 31, 2016 and $73.4 million in unfunded commitments, for a total of $238.0 million.

Commercial Real Estate. The Company makes commercial real estate loans collateralized by owner-occupied 

and nonowner-occupied real estate to finance the purchase of real estate. The Company’s commercial real estate 
loans are collateralized by first liens on real estate, typically have variable interest rates (or five year or less fixed 
rates) and amortize over a 15- to 20-year period. Payments on loans secured by nonowner-occupied properties are 
often dependent on the successful operation or management of the properties. Accordingly, repayment of these loans 
may be subject to adverse conditions in the real estate market or the economy to a greater extent than other types of 
loans. The Company seeks to minimize these risks in a variety of ways, including giving careful consideration to the 
property’s operating history, future operating projections, current and projected occupancy, location and physical 
condition, in connection with underwriting these loans. The underwriting analysis also includes credit verification, 
analysis of global cash flow, appraisals and a review of the financial condition of the borrower.

1-4 Family Residential Loans. The Company’s lending activities also include the origination of 1-4 family 
residential mortgage loans (including home equity loans) collateralized by owner-occupied residential properties 
located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio products which 
generally are amortized over five to 25 years. Loans collateralized by 1-4 family residential real estate generally 
have been originated in amounts of no more than 89% of appraised value or have mortgage insurance. The Company 
requires mortgage title insurance and hazard insurance. The Company retains these portfolio loans for its own 
account rather than selling them into the secondary market. By doing so, the Company incurs interest rate risk as 
well as the risks associated with nonpayments on such loans. The Company’s mortgage department also offers a 
variety of mortgage loan products which are generally amortized over 30 years, including FHA and VA loans. The 
Company sells these longer-term loans into the secondary market.

45

Construction, Land Development and Other Land Loans. The Company makes loans to finance the 

construction of residential and, to a lesser extent, nonresidential properties. Construction loans generally are 
collateralized by first liens on real estate and have floating interest rates. The Company conducts periodic 
inspections, either directly or through an agent, prior to approval of periodic draws on these loans. Underwriting 
guidelines similar to those described above are also used in the Company’s construction lending activities. 
Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of 
a project under construction, and the project is of uncertain value prior to its completion. Because of uncertainties 
inherent in estimating construction costs, the market value of the completed project and the effects of governmental 
regulation on real property, it can be difficult to accurately evaluate the total funds required to complete a project 
and the related loan to value ratio. As a result of these uncertainties, construction lending often involves the 
disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project rather 
than the ability of a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a project prior 
to completion, the Company may not be able to recover all of the unpaid portion of the loan. In addition, the 
Company may be required to fund additional amounts to complete a project and may have to hold the property for 
an indeterminate period of time. Although the Company has underwriting procedures designed to identify what it 
believes to be acceptable levels of risks in construction lending, these procedures may not prevent losses from the 
risks described above.

Agriculture Loans. The Company provides agriculture loans for short-term crop production, including rice, 

cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company evaluates 
agriculture borrowers primarily based on their historical profitability, level of experience in their particular 
agriculture industry, overall financial capacity and the availability of secondary collateral to withstand economic and 
natural variations common to the industry. Because agriculture loans present a higher level of risk associated with 
events caused by nature, the Company routinely makes on-site visits and inspections in order to identify and monitor 
such risks.

Consumer Loans. Consumer loans made by the Company include direct “A”-credit automobile loans, 
recreational vehicle loans, boat loans, home improvement loans, personal loans (collateralized and uncollateralized) 
and deposit account collateralized loans. The terms of these loans typically range from 12 to 180 months and vary 
based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do real estate 
secured loans, particularly in the case of consumer loans that are unsecured or collateralized by rapidly depreciating 
assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide 
an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does not warrant 
further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, 
consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to 
be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various 
federal and state laws may limit the amount which can be recovered on such loans.

Nonperforming assets include loans on nonaccrual status, accruing loans 90 days or more past due, 

repossessed assets and real estate which has been acquired through foreclosure and is awaiting disposition. 
Nonperforming assets do not include PCI loans unless the timing and amount of projected cash flows can no longer 
be reasonably estimated. PCI loans become subject to the Company’s allowance for credit losses methodology when 
a deterioration in projected cash flows is identified.

The Company has several procedures in place to assist it in maintaining the overall quality of its loan 
portfolio. The Company has established underwriting guidelines to be followed by its officers, and the Company 
also monitors its delinquency levels for any negative or adverse trends. Nevertheless, the Company’s loan portfolio 
could become subject to increasing pressures from deteriorating borrower credit due to general economic conditions.

As part of the on-going monitoring of the Company’s loan portfolio and the methodology for calculating the 
allowance for credit losses, management grades each loan from 1 to 9. Depending on the grade, loans in the same 
grade are aggregated and a loss factor is applied to the total loans in the group to determine the allowance for credit 
losses. For certain loans in risk grades 7 to 9, a specific reserve may be required.

The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of 
principal or interest is delinquent for 90 days, or earlier in some cases, unless the loan is in the process of collection 
and the underlying collateral fully supports the carrying value of the loan.

The Company requires appraisals on loans collateralized by real estate. With respect to potential problem 
loans, an evaluation of the borrower’s overall financial condition is made to determine the need, if any, for possible 
write-downs or appropriate additions to the allowance for credit losses.

The Company had $37.5 million in nonperforming assets at December 31, 2017 compared with $48.3 million 
at December 31, 2016 and $43.5 million at December 31, 2015. The nonperforming assets consisted of 99 separate 
credits or other real estate properties at December 31, 2017, compared with 158 at December 31, 2016 and 147 at 
December 31, 2015. If interest on nonaccrual loans had been accrued under the original loan terms, approximately 
$2.7 million, $3.2 million and $3.9 million would have been recorded as income for the years ended December 31, 
2017, 2016 and 2015, respectively.

At December 31, 2017, of the total nonperforming assets, $20.0 million resulted from legacy loans, $12.4 
million resulted from acquired legacy loans, $3.6 million resulted from Non-PCI loans and $1.5 million resulted 
from PCI loans. At December 31, 2016, of the total nonperforming assets, $24.3 million resulted from legacy loans, 
$14.1 million resulted from acquired legacy loans, $6.3 million resulted from Non-PCI loans and $3.5 million 
resulted from PCI loans. A PCI loan becomes impaired when there is a deterioration in projected cash flows after 
acquisition. 

Nonperforming assets were 0.37% of total loans and other real estate at December 31, 2017 compared with 
0.50% of total loans and other real estate at December 31, 2016. The allowance for credit losses as a percentage of 
total nonperforming loans was 319.9% at December 31, 2017 and 261.8% at December 31, 2016.

The allowance for credit losses is a valuation established through charges to earnings in the form of a 
provision for credit losses. The amount of the allowance for credit losses is affected by the following: (1) charge-
offs of loans that occur when loans are deemed uncollectible and decrease the allowance, (2) recoveries on loans 
previously charged off that increase the allowance and (3) provisions for credit losses charged to earnings that 
increase the allowance. Based on an evaluation of the loan portfolio and consideration of the factors listed below, 
management presents a quarterly review of the allowance for credit losses to the Bank’s Board of Directors, 
indicating any change in the allowance since the last review and any recommendations as to adjustments in the 
allowance. Although management believes it uses the best information available to make determinations with 
respect to the allowance for credit losses, further adjustments may be necessary if economic conditions differ from 
the assumptions used in making the initial determinations.

The Company’s allowance for credit losses consists of two components: a specific valuation allowance based 

on probable losses on specifically identified loans and a general valuation allowance based on historical loan loss 
experience, general economic conditions and other qualitative risk factors both internal and external to the 
Company.

In setting the specific valuation allowance, the Company follows a loan review program to evaluate the credit 
risk in the total loan portfolio and assigns risk grades to each loan. Through this loan review process, the Company 
maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess 
the overall quality of the loan portfolio and the adequacy of the allowance for credit losses. All loans that have been 
identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required. 
For certain impaired loans, the Company allocates a specific loan loss reserve primarily based on the value of the 
collateral securing the impaired loan. The specific reserves are determined on an individual loan basis. Loans for 
which specific reserves are provided are excluded from the general valuation allowance described below.

In connection with this review of the loan portfolio, the Company considers risk elements attributable to 

particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include:

for 1-4 family residential mortgage loans, the borrower’s ability to repay the loan, including a 
consideration of the debt to income ratio and employment and income stability, the loan to value ratio, 
and the age, condition and marketability of collateral;

for commercial mortgage loans and multifamily residential loans, the debt service coverage ratio 
(income from the property in excess of operating expenses compared to loan payment requirements), 
operating results of the owner in the case of owner-occupied properties, the loan to value ratio, the age 
and condition of the collateral and the volatility of income, property value and future operating results 
typical of properties of that type;

for construction, land development and other land loans, the perceived feasibility of the project 
including the ability to sell developed lots or improvements constructed for resale or the ability to lease 
property constructed for lease, the quality and nature of contracts for presale or prelease, if any, 
experience and ability of the developer and loan to value ratio;

for commercial and industrial loans, the operating results of the commercial, industrial or professional 
enterprise, the borrower’s business, professional and financial ability and expertise, the specific risks 
and volatility of income and operating results typical for businesses in that category and the value, 
nature and marketability of collateral;

for agriculture real estate loans, the experience and financial capability of the borrower, projected debt 
service coverage of the operations of the borrower and loan to value ratio; and

for non-real estate agriculture loans, the operating results, experience and financial capability of the 
borrower, historical and expected market conditions and the value, nature and marketability of 
collateral.

In addition, for each category, the Company considers secondary sources of income and the financial strength 

and credit history of the borrower and any guarantors.

In determining the amount of the general valuation allowance, management considers factors such as 
historical loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the 
Company’s loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of 
collateral, the evaluation of the Company’s loan portfolio through its internal loan review process, general economic 
conditions, other qualitative risk factors both internal and external to the Company and other relevant factors. Based 
on a review of these factors for each loan type, the Company applies an estimated percentage to the outstanding 
balance of each loan type, excluding any loan that has a specific reserve allocated to it. The Company uses this 
information to establish the amount of the general valuation allowance.

A change in the allowance for credit losses can be attributable to several factors, most notably (1) specific 
reserves identified for impaired loans, (2) historical credit loss information, (3) changes in environmental factors and 
(4) growth in the balance of legacy loans and the re-categorization of fair-valued acquired loans to acquired legacy 
loans, which subjects such loans to the allowance methodology.

50

Changes in the Company’s asset quality are reflected in the allowance in several ways. Specific reserves that 
are calculated on a loan-by-loan basis and the qualitative assessment of all other loans reflect current changes in the 
credit quality of the loan portfolio. Historical credit losses, on the other hand, are based on a three-year look back 
period, which are then applied to estimate current credit losses inherent in the loan portfolio. A deterioration in the 
credit quality of the loan portfolio in the current period would increase the historical credit loss factor to be applied 
in future periods, just as an improvement in credit quality would decrease the historical credit loss factor.

The allowance for credit losses is further determined by the size of the loan portfolio subject to the allowance 

methodology and environmental factors that include Company-specific risk indicators and general economic 
conditions, both of which are constantly changing. The Company evaluates the economic and portfolio-specific 
factors on a quarterly basis to determine a qualitative component of the general valuation allowance. The factors 
include economic metrics, business conditions, delinquency trends, credit concentrations, nature and volume of the 
portfolio and other adjustments for items not covered by specific reserves and historical loss experience. 
Management’s assessment of qualitative factors is a statistically based approach to determine the inherent probable 
loss associated with such factors. Based on the Company’s actual historical loan loss experience relative to 
economic and loan portfolio-specific factors at the time the losses occurred, management is able to identify the 
probabilities of default and loss severity based on current economic conditions. The correlation of historical loss 
experience with current economic conditions provides an estimate of inherent and probable losses that has not been 
previously factored into the general valuation allowance by the determination of specific reserves and recent 
historical losses. Additionally, the Company considers qualitative factors not easily quantified and the possibility of 
model imprecision.

Utilizing the aggregation of specific reserves, historical loss experience and a qualitative component, 

management is able to determine the valuation allowance to reflect the full inherent probable loss.

In determining the allowance for credit losses, management also considers the type of loan (legacy or 
acquired) and the credit quality of the loan. The Company distinguishes between legacy loans and acquired legacy 
loans, which are accounted for under the contractual yield method, and fair-valued acquired loans consisting of Non-
PCI loans and PCI loans, which are accounted for as purchased loans.

Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of 

inherent credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding 
allowance for credit losses is recorded for these loans at acquisition. When a fair-valued acquired loan is renewed at 
its maturity date, the loan is re-categorized as an acquired legacy loan. When a fair-valued acquired loan is modified 
after acquisition, the loan is independently evaluated subsequent to the modification decision to determine whether 
the modification was substantial, and therefore requires that the loan be re-categorized as an acquired legacy loan. 
This determination is based on a discounted cash-flow analysis. Generally, when a change in discounted cash-flow 
of greater than 10% is identified, the fair-valued acquired loan becomes categorized as an acquired legacy loan. If 
and when a fair-valued acquired loan becomes an acquired legacy loan, the acquired legacy loan is evaluated at the 
time of renewal or modification in accordance with the Company’s allowance for credit losses methodology 
described above.

Non-PCI loans that were not deemed impaired subsequent to the acquisition date are considered non-impaired 

and are evaluated as part of the general valuation allowance. Non-PCI loans that have not become impaired 
subsequent to acquisition are segregated into a pool for each acquisition for allowance calculation purposes. For 
each pool, the Company estimates a hypothetical allowance for credit losses also referred to as an “indicated 
reserve” that is calculated in accordance with GAAP requirements. The Company uses the acquired bank’s past loss 
history adjusted for qualitative factors to establish the indicated reserve. The indicated reserve for each pool of Non-
PCI loans is compared with the remaining discount for the respective pool to test for credit quality deterioration and 
the possible need for a loan loss provision. To the extent the remaining discount of the pool is greater than the 
indicated reserve, no additional allowance is necessary. If the remaining discount of the pool is less than the 
indicated reserve, the difference results in an increase to the allowance recorded through a provision for credit 
losses.

51

Non-PCI loans that have deteriorated to an impaired status subsequent to acquisition are evaluated for a 

specific reserve on a quarterly basis which, when identified, is added to the allowance for credit losses. The 
Company reviews impaired Non-PCI loans on a loan-by-loan basis and determines the specific reserve based on the 
difference between the recorded investment in the loan and one of three factors: expected future cash flows, 
observable market price or fair value of the collateral. Because essentially all of the Company’s impaired Non-PCI 
loans have been collateral-dependent, the amount of the specific reserve historically has been determined by 
comparing the fair value of the collateral securing the Non-PCI loan with the recorded investment in such loan. In 
the future, the Company will continue to analyze impaired Non-PCI loans on a loan-by-loan basis and may use an 
alternative measurement method to determine the specific reserve, as appropriate and in accordance with applicable 
accounting standards.

PCI loans are individually monitored on a quarterly basis to assess for deterioration subsequent to acquisition 

and are only subject to the Company’s allowance methodology when a deterioration in projected cash flows is 
identified. If a deterioration in cash flows is identified, an additional provision for credit losses is made. PCI loans 
were recorded at their acquisition date fair values, which were based on expected cash flows and included estimates 
of expected future credit losses. The Company’s estimates of loan fair values at the acquisition date may be adjusted 
for a period of up to one year as the Company continues to evaluate its estimate of expected future cash flows at the 
acquisition date. If the Company determines that losses arose after the acquisition date, the additional losses will be 
reflected as a provision for credit losses. An allowance for credit losses is not calculated for PCI loans that have not 
experienced deterioration subsequent to the acquisition date. See “Critical Accounting Policies” above for more 
information.

As described in the section captioned “Critical Accounting Policies” above, the Company’s determination of 

the allowance for credit losses involves a high degree of judgment and complexity. The Company’s analysis of 
qualitative, or environmental, factors on pools of loans with common risk characteristics, in combination with the 
quantitative historical loss information and specific reserves, provides the Company with an estimate of inherent 
losses. The allowance must reflect changes in the balance of loans subject to the allowance methodology, as well as 
the estimated imminent losses associated with those loans. In the Company’s case, the $1.3 million decrease in the 
allowance for credit losses for the year ended December 31, 2017 was primarily attributable to improved 
environmental factors, partially offset by increases in historical loss rates, loan balances and specific reserves 
identified for loans with deteriorated credit quality.

The following table shows the allocation of the allowance for credit losses among various categories of loans 

and certain other information as of the dates indicated. The allocation is made for analytical purposes and is not 
necessarily indicative of the categories in which future losses may occur. The total allowance is available to absorb 
losses from any loan category.

The Company had gross charge-offs on legacy loans of $9.3 million during the year ended December 31, 2017 

compared with $16.9 million during the year ended December 31, 2016. Partially offsetting these charge-offs were 
recoveries on legacy loans of $2.3 million for the year ended December 31, 2017 compared with $6.0 million for the 
year ended December 31, 2016. Total charge-offs for the year ended December 31, 2017 were $18.9 million, 
partially offset by total recoveries of $3.3 million. Total charge-offs for the year ended December 31, 2016 were 
$27.5 million, partially offset by total recoveries of $7.5 million.

The following tables show the allocation of the allowance for credit losses among various categories of loans 
disaggregated between legacy loans, acquired legacy loans, Non-PCI loans and PCI loans at the dates indicated. The 
allocation is made for analytical purposes and is not necessarily indicative of the categories in which future losses 
may occur. The total allowance is available to absorb losses from any loan category, regardless of whether allocated

At December 31, 2017, the allowance for credit losses totaled $84.0 million or 0.84% of total loans. At 

December 31, 2016, the allowance for credit losses totaled $85.3 million or 0.89% of total loans, and at 
December 31, 2015, the allowance totaled $81.4 million or 0.86% of total loans. The allowance for credit losses at 
December 31, 2017 decreased $1.3 million or 1.5% compared with December 31, 2016. 

At December 31, 2017, $73.4 million of the allowance was attributable to legacy loans compared with $73.8 

million of the allowance at December 31, 2016, a decrease of $439 thousand or 0.6%. This change was primarily 
due to improved environmental factors, partially offset by increases in historical loss rates and legacy loan balances.

At December 31, 2017, $10.3 million of the allowance was attributable to acquired legacy loans compared 
with $11.3 million of the allowance at December 31, 2016, a decrease of $1.0 million or 8.9%. This decrease was 
primarily due to improved environmental factors, partially offset by increases in historical loss rates and specific 
reserves identified for loans with deteriorated credit quality.

At December 31, 2017, $373 thousand of the allowance was attributable to Non-PCI loans compared with 

$185 thousand of the allowance at December 31, 2016, an increase of $188 thousand or 101.6%. This change was 
primarily attributable to an increase in specific reserves identified for loans with deteriorated credit quality.

At December 31, 2017, no part of the allowance was attributable to PCI loans compared with $31 thousand of 

the allowance at December 31, 2016. This decrease was primarily attributable to the charge-off of one loan with 
specific reserves identified at December 31, 2016.

At December 31, 2017, the Company had $34.7 million of total outstanding discounts on Non-PCI and PCI 

loans, of which $28.7 million was accretable.

The Company believes that the allowance for credit losses at December 31, 2017 is adequate to cover 

estimated losses in the loan portfolio as of such date. Nevertheless, the Company could sustain losses in future 
periods that could be substantial in relation to the size of the allowance at December 31, 2017.

Securities

The Company uses its securities portfolio to manage interest rate risk and as a source of income and liquidity 
for cash requirements. At December 31, 2017, the carrying amount of investment securities totaled $9.67 billion, a 
decrease of $54.0 million or 0.6% compared with $9.73 billion at December 31, 2016. At December 31, 2017, 
securities represented 42.8% of total assets compared with 43.6% of total assets at December 31, 2016.

At the date of purchase, the Company is required to classify debt and equity securities into one of three 

categories: held to maturity, trading or available for sale. At each reporting date, the appropriateness of the 
classification is reassessed. Investments in debt securities are classified as held to maturity and measured at 
amortized cost in the financial statements only if management has the positive intent and ability to hold those 
securities to maturity. Securities that are bought and held principally for the purpose of selling them in the near term 
are classified as trading and measured at fair value in the financial statements with unrealized gains and losses 
included in earnings. Investments not classified as either held to maturity or trading are classified as available for 
sale and measured at fair value in the financial statements with unrealized gains and losses reported, net of tax, in a 
separate component of shareholders’ equity until realized.

 Certain investment securities are valued at less than their historical cost. Management evaluates securities for 

other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or 
market conditions warrant such an evaluation.

In determining OTTI, management considers many factors, including: (1) the length of time and the extent to 

which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, 
(3) whether the market decline was affected by macroeconomic conditions and (4) whether the entity has the intent 
to sell the debt security or more likely than not will be required to sell the debt security before its anticipated 
recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity 
and judgment and is based on the information available to management at the time of such determination.

Management has the ability and intent to hold the securities classified as held-to-maturity until they mature, at 

which time the Company will receive full value for the securities. Furthermore, as of December 31, 2017, 
management does not have the intent to sell any of the securities classified as available for sale before a recovery of 
cost. In addition, management believes it is more likely than not that the Company will not have to sell any of its 
investment securities before a recovery of cost. As of December 31, 2017, management believes any impairment in 
the Company’s securities is temporary and no impairment loss has been realized in the Company’s consolidated 
statement of income. The Company recorded no other-than-temporary impairment charges in 2017, 2016 or 2015.

The following table summarizes the contractual maturity of securities and their weighted average yields as of 
December 31, 2017. The contractual maturity of a mortgage-backed security is the date at which the last underlying 
mortgage matures. The weighted average life of the Company’s securities portfolio is 3.97 years, with a modified 
duration of 3.67 at December 31, 2017. Available for sale securities are shown at fair value and held to maturity 
securities are shown at amortized cost. For purposes of the table below, tax-exempt states and political subdivisions 
are calculated on a tax equivalent basis.

The contractual maturity of mortgage-backed securities and collateralized mortgage obligations is not a 

reliable indicator of their expected life because borrowers have the right to prepay their obligations at any time. 
Mortgage-backed securities monthly pay downs cause the average lives of the securities to be much different than 
their stated lives. During a period of increasing interest rates, fixed rate mortgage-backed securities do not tend to 
experience heavy prepayments of principal, and consequently, the average life of this security will be lengthened. If 
interest rates begin to fall, prepayments may increase, thereby shortening the estimated life of this security. 

At December 31, 2017 and 2016, the Company did not own securities of any one issuer (other than the U.S. 

government and its agencies) for which aggregate adjusted cost exceeded 10% of the consolidated shareholders’ 
equity at such respective dates.

The average tax equivalent yield of the securities portfolio was 2.24% as of December 31, 2017 compared 

with 2.24% as of December 31, 2016 and 2.28% as of December 31, 2015. The decrease in yields during 2016 was 
primarily due to the Company’s reinvestment of funds at lower rates in 2016 compared with the rates in 2015. The 
average yield excluding the tax equivalent adjustment was 2.15% for the year ended December 31, 2017 compared 
with 2.13% for the year ended December 31, 2016 and 2.03% for the year ended December 31, 2015. The overall 
non-acquisition growth in the average securities portfolio over the comparable periods was primarily funded by 
average deposit growth and other borrowings.

Mortgage-backed securities are securities that have been developed by pooling a number of real estate 
mortgages and which are principally issued by federal agencies such as Government National Mortgage Association 
(Ginnie Mae), Fannie Mae and Freddie Mac. These securities are deemed to have high credit ratings, and minimum 
regular monthly cash flows of principal and interest are guaranteed by the issuing agencies.

Unlike U.S. Treasury and U.S. government agency securities, which have a lump sum payment at maturity, 

mortgage-backed securities provide cash flows from regular principal and interest payments and principal 
prepayments throughout the lives of the securities. Premiums and discounts on mortgage-backed securities are 
amortized over the expected life of the security and may be impacted by prepayments. As such, mortgage-backed 
securities which are purchased at a premium will generally suffer decreasing net yields as interest rates drop because 
home owners tend to refinance their mortgages resulting in prepayments and an acceleration of premium 
amortization. Securities purchased at a discount will obtain higher net yields in a decreasing interest rate 
environment as prepayments result in a acceleration of discount accretion. At December 31, 2017, 75.1% of the 
mortgage-backed securities held by the Company had contractual final maturities of more than ten years with a 
weighted average life of 4.38 years.

Collateralized mortgage obligations (“CMOs”) are bonds that are backed by pools of mortgages. The pools 

can be Ginnie Mae, Fannie Mae or Freddie Mac pools or they can be private-label pools. CMOs are designed so that 
the mortgage collateral will generate a cash flow sufficient to provide for the timely repayment of the bonds. 
Provided that the collateral cash flow is adequate to meet scheduled bond payments, the mortgage collateral pool 
can be structured to accommodate various desired bond repayment schedules. 

This is accomplished by dividing the bonds into classes to which payments on the underlying mortgage pools are 
allocated in different order. The bond’s cash flow, for example, can be dedicated to one class of bondholders at a 
time, thereby increasing call protection to bondholders. In private-label CMOs, losses on underlying mortgages are 
directed to the most junior of all classes and then to the classes above in order of increasing seniority, which means 
that the senior classes have enough credit protection to be given the highest credit rating by the rating agencies.

Deposits

The Company’s lending and investing activities are primarily funded by deposits. The Company offers a 
variety of deposit accounts having a wide range of interest rates and terms including demand, savings, money 
market and time accounts. The Company relies primarily on competitive pricing policies and customer service to 
attract and retain these deposits.

Total deposits at December 31, 2017 were $17.82 billion, an increase of $514.2 million or 3.0% compared 

with $17.31 billion at December 31, 2016. Total deposits at December 31, 2016 were $17.31 billion, a decrease of 
$373.8 million or 2.1% compared with $17.68 billion at December 31, 2015. Noninterest-bearing deposits at 
December 31, 2017 were $5.62 billion compared with $5.19 billion at December 31, 2016, an increase of $432.3 
million or 8.3%. Noninterest-bearing deposits at December 31, 2016 were $5.19 billion compared with $5.14 billion 
at December 31, 2015, an increase of $54.4 million or 1.1%. Interest-bearing deposits at December 31, 2017 were 
$12.20 billion, an increase of $81.8 million or 0.7% compared with $12.12 billion at December 31, 2016. Interest-
bearing deposits at December 31, 2016 were $12.12 billion, a decrease of $428.2 million or 3.4% compared with 
$12.54 billion at December 31, 2015.

FHLB advances and long-term notes payable—The Company has an available line of credit with the FHLB of 

Dallas, which allows the Company to borrow on a collateralized basis. The Company’s FHLB advances are 
typically considered short-term borrowings used to manage liquidity as needed. Maturing advances are replaced by 
drawing on available cash, making additional borrowings or through increased customer deposits. At December 31, 
2017, the Company had total funds of $5.77 billion available under this line, of which a total amount of $505.2 
million was outstanding. FHLB advances were $500.0 million at December 31, 2017 with a weighted average 
interest rate of 1.21%. Long-term notes payable were $5.2 million at December 31, 2017, with an average interest 
rate of 5.70%. The maturity dates on the FHLB notes payable range from the years 2018 to 2027 and have interest 
rates ranging from 4.51% to 6.10%.

Securities sold under repurchase agreements with Company customers—At December 31, 2017, the 

Company had $324.2 million in securities sold under repurchase agreements compared with $320.4 million at 
December 31, 2016, with weighted average rates paid of 0.39% and 0.29% for the years ended December 31, 2017 
and 2016, respectively. Repurchase agreements are generally settled on the following business day; however, 
approximately $9.8 million of repurchase agreements outstanding at December 31, 2017 have maturity dates ranging 
from 6 to 24 months. All securities sold under agreements to repurchase are collateralized by certain pledged 
securities.

Junior Subordinated Debentures

On January 1, 2016, in connection with the acquisition of Tradition, the Company assumed $7.2 million in 
junior subordinated debentures. During the second quarter of 2016, the Company redeemed all of its outstanding 
junior subordinated debentures. Accordingly, as of December 31, 2017 and 2016, the Company had no junior 
subordinated debentures outstanding.

Interest Rate Sensitivity and Market Risk

The Company’s asset liability and funds management policy provides management with the guidelines for 

effective funds management, and the Company has established a measurement system for monitoring its net interest 
rate sensitivity position. The Company manages its sensitivity position within established guidelines.

As a financial institution, the Company’s primary component of market risk is interest rate volatility. 
Fluctuations in interest rates will ultimately impact both the level of income and expense recorded on most of the 
Company’s assets and liabilities, and the market value of all interest-earning assets and interest-bearing liabilities, 
other than those which have a short term to maturity. Interest rate risk is the potential of economic losses due to 
future interest rate changes. These economic losses can be reflected as a loss of future net interest income and/or a 
loss of current fair market values. The objective is to measure the effect on net interest income and to adjust the 
balance sheet to minimize the inherent risk while at the same time maximizing income.

The Company manages its exposure to interest rates by structuring its balance sheet in the ordinary course of 
business. The Company does not enter into instruments such as leveraged derivatives, interest rate swaps, financial 
options, financial future contracts or forward delivery contracts for the purpose of reducing interest rate risk. Based 
upon the nature of the Company’s operations, with the exception of how commodity prices may impact the 
Company’s borrowers’ ability to repay loans, the Company is not subject to foreign exchange or commodity price 
risk. The Company does not own any trading assets.

59

The Company’s exposure to interest rate risk is managed by the Asset Liability Committee (“ALCO”), which 

is composed of senior officers of the Company, in accordance with policies approved by the Company’s Board of 
Directors. The ALCO formulates strategies based on appropriate levels of interest rate risk. In determining the 
appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital of the current outlook 
on interest rates, potential changes in interest rates, regional economies, liquidity, business strategies and other 
factors. The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest 
rate changes, the book and market values of assets and liabilities, unrealized gains and losses, purchase and sale 
activities, commitments to originate loans and the maturities of investments and borrowings. Additionally, the 
ALCO reviews liquidity, cash flow flexibility, maturities of deposits and consumer and commercial deposit activity. 
Management uses two methodologies to manage interest rate risk: (1) an analysis of relationships between interest-
earning assets and interest-bearing liabilities; and (2) an interest rate shock simulation model. The Company has 
traditionally managed its business to reduce its overall exposure to changes in interest rates.

The Company uses an interest rate risk simulation model and shock analysis to test the interest rate sensitivity 

of net interest income and the balance sheet. Contractual maturities and repricing opportunities of loans are 
incorporated in the model as are prepayment assumptions, maturity data and call options within the investment 
portfolio. Assumptions based on past experience are incorporated into the model for nonmaturity deposit accounts. 
The assumptions used are inherently uncertain, and, as a result, the model cannot precisely measure future net 
interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual 
results will differ from the model’s simulated results due to timing, magnitude and frequency of interest rate changes 
as well as changes in market conditions and the application and timing of various management strategies.

The Company utilizes static balance sheet rate shocks to estimate the potential impact on net interest income 

of changes in interest rates under various rate scenarios. This analysis estimates a percentage of change in the metric 
from the stable rate base scenario versus alternative scenarios of rising and falling market interest rates by 
instantaneously shocking a static balance sheet.    

The following table summarizes the simulated change in net interest income at the 12-month horizon, 

considering the balance sheet composition as of December 31, 2017:

Change in Interest
Rates (Basis Points)
+200
+100
Base
-100

Percent Change in
Net Interest Income
1.5%
1.4%
0.0%
(7.6)%

The results are significantly influenced by the behavior of demand, money market and savings deposits and 

the overall balance sheet composition during such rate fluctuations. The Company has found that, historically, 
interest rates on these deposits change more slowly than changes in the discount and federal funds rates. This 
assumption is incorporated into the simulation model and is generally not fully reflected in a gap analysis. The 
assumptions incorporated into the model are inherently uncertain and, as a result, the model cannot precisely 
measure future net interest income or precisely predict the impact of fluctuations in market interest rates on net 
interest income. Actual results will differ from the model’s simulated results due to timing, magnitude and 
frequency of interest rate changes as well as changes in market conditions and the application and timing of various 
strategies.

Liquidity

Liquidity involves the Company’s ability to raise funds to support asset growth and acquisitions or reduce 
assets to meet deposit withdrawals and other payment obligations, to maintain reserve requirements and otherwise to 
operate the Company on an ongoing basis and manage unexpected events. During 2017 and 2016, the Company’s 
liquidity needs have primarily been met by growth in core deposits, security and loan maturities, amortizing 
investment and loan portfolios and advances from the FHLB of Dallas. Although access to purchased funds from 
correspondent banks is available and has been utilized on occasion to take advantage of investment opportunities, 
the Company does not generally rely on this external funding source.

The following table illustrates, during the years presented, the mix of the Company’s funding sources and the 

average assets in which those funds are invested as a percentage of the Company’s average total assets for the 
periods indicated. Average assets totaled $22.34 billion for 2017 compared with $21.88 billion for 2016.

The Company’s largest source of funds is deposits and its largest uses of funds are securities and loans. The 

Company does not expect a change in the source or use of its funds in the foreseeable future. The Company’s 
average loans increased 2.0% for the year ended December 31, 2017 compared with the year ended December 31, 
2016. The Company predominantly invests excess deposits in government-backed securities until the funds are 
needed to fund loan growth. The Company’s securities portfolio has a weighted average life of 3.97 years and a 
modified duration of 3.67 at December 31, 2017.

As of December 31, 2017, the Company had outstanding $2.38 billion in commitments to extend credit and 
$72.4 million in commitments associated with outstanding standby letters of credit. Since commitments associated 
with letters of credit and commitments to extend credit may expire unused, the total outstanding may not necessarily 
reflect the actual future cash funding requirements.

As of December 31, 2017, the Company had no exposure to future cash requirements associated with known 

uncertainties or capital expenditures of a material nature.

As of December 31, 2017, the Company had cash and cash equivalents of $392.3 million compared with 

$437.4 million at December 31, 2016. The decrease was primarily due to the net repayments of other short-term 
borrowings of $485.0 million and the net increase in loans held for investment of $387.5 million, partially offset by 
the net increase in noninterest-bearing deposits of $432.3 million and net income of $272.2 million.

The following table summarizes the Company’s contractual obligations and other commitments to make 
future payments as of December 31, 2017 (other than deposit obligations and securities sold under repurchase 
agreements). The Company’s future cash payments associated with its contractual obligations pursuant to its FHLB 
notes payable and operating leases as of December 31, 2017 are summarized below. The future interest payments 
were calculated using the current rate in effect at December 31, 2017. Payments for FHLB notes payable include 
interest of $364 thousand that will be paid over the future periods. Payments related to leases are based on actual 
payments specified in underlying contracts.

 Off-Balance Sheet Items

In the normal course of business, the Company enters into various transactions that, in accordance with 
GAAP, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the 
financing needs of its customers. These transactions include commitments to extend credit and standby letters of 
credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts 
recognized in the consolidated balance sheets.

The Company’s commitments associated with outstanding standby letters of credit and commitments to 

extend credit expiring by period as of December 31, 2017 are summarized below. Since commitments associated 
with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily 
reflect the actual future cash funding requirements.

Standby Letters of Credit. Standby letters of credit are written conditional commitments issued by the 

Company to guarantee the payment by or performance of a customer to a third party. If the customer does not 
perform in accordance with the terms of the agreement with the third party, the Company would be required to fund 
the commitment. The maximum potential amount of future payments the Company could be required to make is 
represented by the contractual amount of the commitment. If the commitment is funded, the Company would be 
entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit 
arrangements contain security and debt covenants similar to those contained in loan agreements.

Commitments to Extend Credit. The Company enters into contractual commitments to extend credit, normally 
with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the 
Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the 
time of loan funding. The Company minimizes its exposure to loss under these commitments by subjecting them to 
credit approval and monitoring procedures. Management assesses the credit risk associated with certain 
commitments to extend credit in determining the level of the allowance for credit losses.

Capital Resources

Capital management consists of providing equity to support the Company’s current and future operations. The 

Company is subject to capital adequacy requirements imposed by the Federal Reserve Board, and the Bank is 
subject to capital adequacy requirements imposed by the FDIC. Both the Federal Reserve Board and the FDIC have 
adopted risk-based capital requirements for assessing bank holding company and bank capital adequacy. These 
standards define capital and establish minimum capital requirements in relation to assets and off-balance sheet 
exposure, adjusted for credit risk.

In July 2013, the Federal Reserve Board and the FDIC published the Basel III Capital Rules establishing a 
new comprehensive capital framework for U.S. banking organizations. The Basel III Capital Rules, among other 
things, (1) introduced a new capital measure called “Common Equity Tier 1” (“CET1”), (2) specified that Tier 1 
capital consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (3) defined 
CET1 narrowly by requiring that most deductions/ adjustments to regulatory capital measures be made to CET1 and 
not to the other components of capital and (4) expanded the scope of the deductions/ adjustments as compared to 
existing regulations.

The initial minimum capital ratios under the Basel III Capital Rules that became effective as of January 1, 
2015 were (1) 4.5% CET1 to risk-weighted assets, (2) 6.0% Tier 1 capital to risk-weighted assets, (3) 8.0% Total 
capital to risk-weighted assets and (4) 4.0% Tier 1 capital to average quarterly assets as reported on consolidated 
financial statements (known as the “leverage ratio”).

The Basel III Capital Rules require a “capital conservation buffer,” composed entirely of CET1, in addition to 

the minimum risk-weighted asset capital ratios. The implementation of the capital conservation buffer began on 
January 1, 2016 at the 0.625% level and is being phased in over a four-year period (increasing by that amount on 
each subsequent January 1, until it reaches 2.5% on January 1, 2019). The required phase-in buffer during 2017 was 
1.25%.

When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company to maintain an 

additional capital conservation buffer of 2.5% CET1, effectively resulting in minimum ratios of (1) CET1 to risk-
weighted assets of 7.0%, (2) Tier 1 capital to risk-weighted assets of 8.5%, (3) Total capital (that is, Tier 1 plus Tier 
2) to risk-weighted assets of 10.5% and (4) a leverage ratio of 4.0%. The Bank is subject to capital adequacy 
guidelines of the FDIC that are substantially similar to the Federal Reserve Board’s guidelines. Also pursuant to 
FDICIA, the FDIC has promulgated regulations setting the levels at which an insured institution such as the Bank 
would be considered “well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly 
undercapitalized” and “critically undercapitalized.” Under the FDIC’s regulations, the Bank is classified “well-
capitalized” for purposes of prompt corrective action.

Total shareholders’ equity increased to $3.82 billion at December 31, 2017, compared with $3.64 billion at 

December 31, 2016, an increase of $181.8 million or 5.0%. This increase was primarily the result of net income of 
$272.2 million, partially offset by dividends paid on common stock of $95.9 million.

ITEM  9A. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, the 
Company carried out an evaluation, under the supervision and with the participation of its management, including its 
Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its 
disclosure controls and procedures. In designing and evaluating the disclosure controls and procedures, management 
recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable 
assurance of achieving the desired control objectives, and management was required to apply judgment in evaluating 
its controls and procedures. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial 
Officer concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-
15(e) under the Exchange Act), were effective as of the end of the period covered by this report.

Changes in internal control over financial reporting. There were no changes in the Company’s internal 
control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred 
during the quarter ended December 31, 2017, that have materially affected, or are reasonably likely to materially 
affect, the Company’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control 
over financial reporting. The Company’s internal control over financial reporting is a process designed under the 
supervision of the Company’s Chief Executive Officer and Chief Financial Officer to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external 
purposes in accordance with generally accepted accounting principles.

As of December 31, 2017, management assessed the effectiveness of the Company’s internal control over 
financial reporting based on the criteria for effective internal control over financial reporting established in “Internal 
Control—Integrated Framework,” issued by the Committee of Sponsoring Organizations (“COSO”) of the 
Treadway Commission (“2013 Framework”). This assessment included controls over the preparation of the 
schedules equivalent to the basic financial statements in accordance with the instructions for the Consolidated 
Financial Statements for Bank Holding Companies (Form FR Y-9C) to meet the reporting requirements of 
Section 112 of the Federal Deposit Insurance Corporation Improvement Act. Based on the assessment, management 
determined that the Company maintained effective internal control over financial reporting as of December 31,

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the shareholders and the Board of Directors of Prosperity Bancshares, Inc. 

Opinion on Internal Control over Financial Reporting 

We  have  audited  the  internal  control  over  financial  reporting  of  Prosperity  Bancshares,  Inc.  and  subsidiaries  (the 
“Company”) as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework 
(2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  Because 
management's  assessment  and  our  audit  were  conducted  to  meet  the  reporting  requirements  of  Section  112  of  the 
Federal Deposit Insurance Corporation Improvement Act (FDICIA), management's assessment and our audit of the 
Company's  internal  control  over  financial  reporting  included  controls  over  the  preparation  of  the  schedules 
equivalent  to  the  basic  financial  statements  in  accordance  with  the  instructions  for  the  Consolidated  Financial 
Statements for Bank Holding Companies (Form FR Y-9C). In our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in 
Internal Control — Integrated Framework (2013) issued by COSO.

We  have  not  examined  and,  accordingly,  we  do  not  express  an  opinion  or  any  other  form  of  assurance  on 
management's statement referring to compliance with laws and regulations.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States)  (PCAOB),  the  consolidated  financial  statements  as  of  and  for  the  year  ended  December  31,  2017,  of  the 
Company and our report dated February 27, 2018, expressed an unqualified opinion on those financial statements.

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 
Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the 
Company’s internal control over financial reporting based on our audit. We 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 Prosperity Bancshares, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Prosperity Bancshares, Inc. and subsidiaries (the 
“Company”)  as  of  December  31,  2017  and  2016,  the  related  consolidated  statements  of  income,  comprehensive 
income, changes in shareholders' equity, and cash flows, for each of the three years in the period ended December 
31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial 
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 
and  2016,  and  the  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended 
December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

We have also 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,  2017,  based  on 
criteria  established  in  Internal  Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission  and  our  report  dated  February  27,  2018,  expressed  an  unqualified 
opinion on the Company's internal control over financial reporting.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING 
POLICIES

Nature of Operations—Prosperity Bancshares, Inc.® (“Bancshares”) and its subsidiary, Prosperity Bank® 

(the “Bank”, collectively referred to as the “Company”), provide retail and commercial banking services.

As of December 31, 2017, the Bank operated 242 full-service banking locations; with 65 in the Houston area, 

including The Woodlands; 29 in the South Texas area including Corpus Christi and Victoria; 33 in the Dallas/Fort 
Worth, Texas area; 22 in the East Texas area; 29 in the Central Texas area, including Austin and San Antonio; 34 in 
the West Texas area including Lubbock, Midland-Odessa and Abilene; 16 in the Bryan/College Station area; 6 in the 
Central Oklahoma area; and 8 in the Tulsa, Oklahoma area.

Summary of Significant Accounting and Reporting Policies—The accounting and reporting policies of the 

Company conform to generally accepted accounting principles (“GAAP”) and the prevailing practices within the 
financial services industry. A summary of significant accounting and reporting policies are as follows:

Basis of Presentation—The consolidated financial statements include the accounts of Bancshares and its 

subsidiaries. Intercompany transactions have been eliminated in consolidation. Operations are managed and 
financial performance is evaluated on a company-wide basis. Accordingly, all of the Company’s banking operations 
are considered by management to be aggregated in one reportable operating segment. Because the overall banking 
operations comprise the vast majority of the consolidated operations, no separate segment disclosures are presented.

Use of Estimates—The preparation of financial statements in conformity with GAAP requires management to 

make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and 
expenses during the reporting period. Such estimates include, but are not limited to certain fair value measures 
including the calculation of stock-based compensation, the valuation of goodwill and available for sale and held to 
maturity securities and the calculation of allowance for credit losses. Actual results could differ from these 
estimates.

Securities —Securities held to maturity are carried at cost, adjusted for the amortization of premiums and the 
accretion of discounts. Management has the positive intent and the Company has the ability to hold these assets until 
their estimated maturities.

Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings 

and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the 
available for sale portfolio may be used as part of the Company’s asset/liability strategy and may be sold in response 
to changes in interest rate risk, prepayment risk or other similar economic factors.

For debt securities, when other-than-temporary impairment (“OTTI”) occurs, the amount of the OTTI 

recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be 
required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity 
intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis 
less any current-period credit loss, the OTTI will be recognized in earnings equal to the entire difference between 
the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell 
the security and it is not more likely than not that the entity will be required to sell the security before recovery of its 
amortized cost basis less any current-period loss, the OTTI will be separated into the amount representing the credit-
related portion of the impairment loss (“credit loss”) and the noncredit portion of the impairment loss (“noncredit 
portion”). The amount of the total OTTI related to the credit loss is determined based on the difference between the 
present value of cash flows expected to be collected and the amortized cost basis and such difference is recognized 
in earnings. The amount of the total OTTI related to the noncredit portion is recognized in other comprehensive 

80

income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings shall 
become the new amortized cost basis of the investment.

Premiums and discounts are amortized and accreted to operations using the level-yield method of accounting, 
adjusted for prepayments as applicable. The specific identification method of accounting is used to compute gains or 
losses on the sales of these assets. Interest earned on these assets is included in interest income.

Loans Held for Sale—Loans held for sale are carried at the lower of aggregate cost or market value. 
Premiums, discounts and loan fees (net of certain direct loan origination costs) on loans held for sale are deferred 
until the related loans are sold or repaid. Gains or losses on loan sales are recognized at the time of sale and 
determined using the specific identification method.

Loans Held for Investment—Loans originated and held for investment are stated at the principal amount 

outstanding, net of unearned fees. The related interest income for multipayment loans is recognized principally by 
the simple interest method; for single payment loans, such income is recognized using the straight-line method.

The Company has two general categories of loans in its portfolio. Loans originated by the Bank and made 
pursuant to the Company’s loan policy and procedures in effect at the time the loan was made are referred to as 
“legacy loans” and loans acquired in a business combination are referred to as “acquired loans.” Acquired loans are 
initially recorded at fair value based on a discounted cash flow valuation methodology that considers, among other 
things, interest rates, projected default rates, loss given default and recovery rates, with no carryover of any existing 
allowance for credit losses. Those acquired loans that are renewed or substantially modified after the date of the 
business combination, thereby subjecting them to the Company’s allowance for credit losses methodology, are 
referred to as “acquired legacy loans.” Modifications are reviewed for determination of troubled debt restructuring 
status independently of this process. In certain instances, acquired loans to one borrower may be combined or 
otherwise re-originated such that they are re-categorized as legacy loans. Acquired loans with a fair value discount 
or premium at the date of the business combination that remained at the reporting date are referred to as “fair-valued 
acquired loans.” All fair-valued acquired loans are further categorized into “Non-PCI loans” and “PCI loans” 
(purchased credit impaired loans). Acquired loans with evidence of credit quality deterioration at acquisition are 
reviewed to determine if it is probable that the Company will not be able to collect all contractual amounts due, 
including both principal and interest. When both conditions exist, such loans are accounted for as PCI loans.

The Company estimates the total cash flows expected to be collected from the PCI loans, which include 

undiscounted expected principal and interest, using credit risk, interest rate and prepayment risk assessments that 
incorporate management’s best estimate of current key assumptions such as default rates, loss severity and payment 
speeds. The excess of the undiscounted total cash flows expected to be collected over the fair value of the related 
PCI loans represents the accretable yield, which is recognized as interest income on a level-yield basis over the life 
of the related loan. The difference between the undiscounted contractual principal and interest and the undiscounted 
total cash flows expected to be collected is the nonaccretable difference, which reflects the impact of estimated 
credit losses and other factors. Subsequent increases in expected cash flows will result in a recovery of any 
previously recorded allowance for credit losses, to the extent applicable, and a reclassification from nonaccretable 
difference to accretable yield, which is recognized prospectively over the then remaining life of the loan. Subsequent 
decreases in expected cash flows will result in an impairment charge to the provision for credit losses, resulting in an 
addition to the allowance for credit losses, and a reclassification from accretable yield to nonaccretable difference.

A loan disposal, which may include a loan sale, receipt of payment in full from the borrower or foreclosure, 

results in removal of the loan from the balance sheet at its allocated carrying amount and accretion of any remaining 
fair value discount to income. 

Nonrefundable Fees and Costs Associated with Lending Activities—Loan origination fees in excess of the 

associated costs are recognized over the life of the related loan as an adjustment to yield using the interest method.

Loan commitment fees and loan origination costs are deferred and recognized as an adjustment of yield by the 

interest method over the related loan life or, if the commitment expires unexercised, recognized in income upon 
expiration of the commitment.

81

Nonperforming and Past Due Loans—Included in the nonperforming loan category are loans which have 

been categorized by management as nonaccrual because collection of interest is doubtful and loans which have been 
restructured to provide a reduction in the interest rate or a deferral of interest or principal payments. When the 
payment of principal or interest on a loan is delinquent for 90 days, or earlier in some cases, the loan is placed on 
nonaccrual status unless the loan is in the process of collection and the underlying collateral fully supports the 
carrying value of the loan. If the decision is made to continue accruing interest on the loan, periodic reviews are 
made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status, interest accrued but not 
yet collected prior to the determination of uncollectibility is charged to operations. Interest accrued during prior 
periods is charged to the allowance for credit losses. Any payments received on nonaccrual loans are applied first to 
outstanding principal of the loan amount, next to the recovery of charged-off loan amounts and finally, any excess is 
treated as recovery of lost interest.

Restructured loans are those loans on which concessions in terms have been granted because of a borrower’s 

financial difficulty. Interest is generally not accrued on such loans in accordance with the new terms.

Allowance for Credit Losses—The allowance for credit losses is a valuation allowance available for losses 
incurred on loans. All losses are charged to the allowance when the loss actually occurs or when a determination is 
made that such a loss is probable and reasonably estimatable. Recoveries are credited to the allowance at the time of 
recovery.

Throughout the year, management estimates the probable level of losses to determine whether the allowance 
for credit losses is adequate to absorb losses inherent in the loan portfolio. Based on these estimates, an amount is 
charged to the provision for credit losses and credited to the allowance for credit losses in order to adjust the 
allowance to a level determined to be adequate to absorb losses.

In making its evaluation of the adequacy of the allowance for credit losses, management considers factors 

such as historical loan loss experience, the amount of nonperforming assets and related collateral, the volume, 
growth and composition of the Company’s loan portfolio, current economic conditions that may affect the 
borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its 
internal loan review process and other relevant factors.

Estimates of credit losses involve an exercise of judgment. While it is possible that in the short term the 
Company may sustain losses which are substantial in relation to the allowance for credit losses, it is the judgment of 
management that the allowance for credit losses reflected in the consolidated balance sheets is adequate to absorb 
probable losses that exist in the loan portfolio as of December 31, 2017.

The Company’s allowance for credit losses consists of two elements: (1) specific valuation allowances based 

on probable losses on impaired loans; and (2) a general valuation allowance based on historical loan loss experience, 
general economic conditions and other qualitative risk factors both internal and external to the Company. A loan is 
defined as impaired if, based on current information and events, it is probable that a creditor will be unable to collect 
all amounts due, both interest and principal, according to the contractual terms of the loan agreement. The allowance 
for credit losses related to impaired loans is determined based on the difference of carrying value of loans and the 
present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, the 
loan’s observable market price or the fair value of the collateral if the loan is collateral dependent.

Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of 
credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance 
for credit losses is recorded for these loans at acquisition. These fair value estimates associated with acquired loans, 
based on a discounted cash flow model, include estimates related to market interest rates and undiscounted 
projections of future cash flows that incorporate expectations of prepayments and the amount and timing of 
principal, interest and other cash flows, as well as any shortfalls thereof. At period-end after acquisition, the fair-
valued acquired loans from each acquisition are reassessed to determine whether an addition to the allowance for 
credit losses is appropriate due to further credit quality deterioration. Methods utilized to estimate any subsequently 
required allowance for acquired loans not deemed credit impaired at acquisition are similar to originated loans; 
however, the estimate of loss is based on the unpaid principal balance and then compared to any remaining 

82

unaccreted purchase discount. To the extent that the calculated loss is greater than the remaining unaccreted 
purchase discount, an allowance is recorded for such difference.

Premises and Equipment—Premises and equipment are carried at cost less accumulated depreciation. 
Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the 
assets which range from three to 39 years. Leasehold improvements are amortized using the straight-line method 
over the periods of the leases or the estimated useful lives, whichever is shorter.

Goodwill —Goodwill is annually assessed for impairment or when events or changes in circumstances 

indicate that the carrying amount of the asset may not be recoverable.

Under Accounting Standards Codification (“ASC”) topic 350-20, “Intangibles—Goodwill and Other—
Goodwill” companies have the option to first assess qualitative factors to determine whether it is more likely than 
not that the fair value of a reporting unit is less than its carrying amount as a basis for determining the need to 
perform step one of the annual test for goodwill impairment. An entity has an unconditional option to bypass the 
qualitative assessment described in the preceding paragraph for any reporting unit in any period and proceed directly 
to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative 
assessment in any subsequent period. 

If the Company bypasses the qualitative assessment, a two-step goodwill impairment test would be performed. 

The first step of the goodwill impairment test compares the estimated fair value of the Company’s reporting unit to 
its carrying value. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill of the 
reporting unit is not impaired. If the estimated fair value of the reporting unit is less than the carrying value, the 
second step must be performed to determine the implied fair value of the reporting unit’s goodwill and the amount 
of goodwill impairment, if any. The Company currently utilizes a qualitative assessment for its annual goodwill 
impairment analysis.

Amortization of Core Deposit Intangibles—Core deposit intangibles are being amortized on a non-pro rata 

basis over an estimated life of 10 to 15 years.

Income Taxes— The Company files a consolidated federal income tax return and a consolidated Oklahoma 

state income tax return. Since 2014, the Bank files an Arkansas state income tax return. 

Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to differences 
between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and 
are recorded in other assets or other liabilities on the Company’s consolidated balance sheets. The Company records 
uncertain tax positions in accordance with ASC topic 740 “Income Taxes” on the basis of a two-step process 
whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained on 
the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not 
recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely 
to be realized upon ultimate settlement with the related tax authority.

Realization of net deferred tax assets is based upon the level of historical income and on estimates of future 

taxable income. Although realization is not assured, management believes it is more likely than not that all of the net 
deferred tax assets will be realized.  Interest and/or penalties related to income taxes are reported as a component of 
income tax expense. Beginning in 2017, the income tax effects related to settlements of share-based payment awards 
are reported in earnings as an increase (or decrease) to income tax expense (see Note 11 - Income Taxes).

Stock-Based Compensation—The Company accounts for stock-based employee compensation plans using 

the fair value-based method of accounting. The expense associated with stock-based compensation is recognized 
over the vesting period of each individual arrangement. The fair value of stock options granted is estimated at the 
date of grant using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions. 
The fair value of restricted stock awards is based on the current market price on the date of grant.

83

Cash and Cash Equivalents—For purposes of reporting cash flows, cash and cash equivalents include cash 

and due from banks as well as federal funds sold that mature in three days or less.

Earnings Per Common Share—Basic earnings per common share are calculated using the two-class method. 

The two-class method provides that unvested share-based payment awards that contain nonforfeitable rights to 
dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the 
computation of basic earnings per share.

Diluted earnings per common share is computed using the weighted-average number of shares determined for 

the basic earnings per common share computation plus the potential dilution that could occur if securities or other 
contracts to issue common stock were exercised or converted into common stock using the treasury stock method. 
As of December 31, 2017, all outstanding stock options issued by the Company have been exercised and there is no 
potential dilution of weighted-average shares. 

The following table illustrates the computation of basic and diluted earnings per share:

New Accounting Standards

Accounting Standards Updates (“ASU”)

ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain 

Tax Effects from Accumulated Other Comprehensive Income.” The amendments of ASU 2018-02 allow a 
reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting 
from the Tax Cuts and Jobs Act. ASU 2018-02 is effective for all entities beginning January 1, 2019 and is not 
expected to have a significant impact on the Company’s financial statements. 

ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350).” ASU 2017-04 simplifies the subsequent 
measurement of goodwill by eliminating the second step of the goodwill impairment test, which required computing 
the implied fair value of goodwill. 
Under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by 
comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized 
for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized 
should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for 
the Company on January 1, 2020 and is not expected to have a significant impact on the Company’s financial 
statements.

ASU 2017-01, “Business Combinations (Topic 805).” ASU 2017-01 is intended to clarify or correct 
unintended application of ASU 2014-09 “Revenue from Contract with Customers (Topic 606).” ASU 2017-01 
clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether 
transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Additionally, the 
amendments in this update provide a more robust framework to assist entities in evaluating whether a set of assets 
and activities constitutes a business. Lastly, the amendments in this update narrow the definition of the term output 
so that the term is consistent with how outputs are described in Topic 606. ASU 2017-01 is effective for the 
Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial 
statements. 

ASU 2016-18, “Statement of Cash Flows (Topic 230) – Restricted Cash.” ASU 2016-18 requires the 
Statement of Cash Flows to explain the change during the period in the total of cash, cash equivalents and amounts 
generally described as restricted cash or restricted cash equivalents. Therefore, restricted cash or cash equivalents 
should be included with cash and cash equivalents when recording the beginning-of-period and end-of-period total 
amounts on the Statement of Cash Flows. ASU 2016-18 is effective for the Company on January 1, 2018 and is not 
expected to have a significant impact on the Company’s financial statements. 

ASU 2016-15, “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash 
Payments.” ASU 2016-15 addresses certain cash receipts and cash payments with the objective of reducing the 
existing diversity in practice. ASU 2016-15 is effective for the Company on January 1, 2018 and is not expected to 
have a significant impact on the Company's financial statements.

ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326)—Measurement of Credit Losses on 
Financial Instruments.” ASU 2016-13 requires a financial asset (or a group of financial assets) measured at 
amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit 
losses is based on relevant information about past events, including historical experience, current conditions, and 
reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use 
judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. 
Additionally, available for sale debt securities may realize value either through collection of contractual cash flows 
or through sale of the security at fair value. Therefore, the amendments limit the amount of the allowance for credit 
losses to the difference between amortized cost and fair value. ASU 2016-13 will be effective for the Company as of 
January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on the Company’s 
financial statements.

ASU 2016-09, “Compensation - Stock Compensation (Topic 718)—Improvements to Employee Share-Based 

Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based awards paid to employees. The 
amended guidance 1) requires excess tax benefits and tax deficiencies on share-based awards payments to 
employees to be recognized directly to income tax expense or benefit in the Consolidated Statement of Income 
rather than to capital surplus; 2) requires excess tax benefits to be included as operating activities on the 
Consolidated Statements of Cash Flows; 3) provides entities with the option of making an accounting policy election 
to account for forfeitures of share-based payments as they occur instead of estimating the awards expected to be 
forfeited; and 4) changes the threshold to qualify for equity classification to permit withholdings up to the maximum 
statutory tax rate in the applicable jurisdiction. In addition, excess tax benefits and tax deficiencies are considered 
discrete items in the reporting period they occur and are not included in the estimate of an entity’s annual effective 
tax rate.  The Company adopted ASU 2016-09 on January 1, 2017 and elected to recognize forfeitures as they occur. 
Implementation of ASU 2016-09 will add volatility to tax expense as the Company’s stock price changes.  The 
adoption of ASU 2016-09 did not have a significant impact on the Company’s financial statements.  

ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires that lessees and lessors recognize lease assets and 

lease liabilities on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 is 
effective for public companies for annual periods beginning January 1, 2019, including interim periods within those 
fiscal years. The Company is currently evaluating the potential impact of ASU 2016-02 on the Company’s financial 
statements.

85

ASU 2016-01 “Financial Instruments—Overall (Subtopic 825-10) Recognition and Measurement of Financial 
Assets and Financial Liabilities” ASU 2016-01 addresses certain aspects of recognition, measurement, presentation, 
and disclosure of financial instruments. ASU 2016-01 (1) requires equity investments (except those accounted for 
under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair 
value with changes in fair value recognized in net income; (2) simplifies the impairment assessment of equity 
investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 
(3) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for 
entities that are not public business entities; (4) eliminates the requirement for public business entities to disclose the 
method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial 
instruments measured at amortized cost on the balance sheet; (5) requires public business entities to use the exit 
price notion when measuring the fair value of financial instruments for disclosure purposes; (6) requires an entity to 
present separately in other comprehensive income the portion of the total change in the fair value of a liability 
resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at 
fair value in accordance with the fair value option for financial instruments; (7) requires separate presentation of 
financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or 
loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (8) clarifies 
that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale 
securities in combination with the entity’s other deferred tax assets. The amendments in this update affect all entities 
that hold financial assets or owe financial liabilities. ASU 2016-01 is effective for the Company on January 1, 2018 
and is not expected to have a significant impact on the Company’s financial statements.

ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 supersedes the revenue 
recognition requirements in Revenue Recognition (Topic 605), and most industry-specific guidance throughout the 
Industry Topics of the Codification. The core principle of ASU 2014-09 is that an entity should recognize revenue to 
depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which 
the entity expects to be entitled in exchange for those goods or services.  In addition, the FASB has issued targeted 
updates to clarify specific implementation issues of ASU 2014-09. These updates include ASU 2016-08 - Principal 
versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 - Identifying Performance 
Obligations and Licensing, ASU 2016-12 - Narrow-Scope Improvements and Practical Expedients and ASU 2016-
20 - Technical Corrections and Improvements to Topic 606 - Revenue from Contract with Customers. These 
amendments do not change the core principles in ASU 2014-09. The Company’s primary sources of revenue are 
comprised of net interest income on financial assets and liabilities, which are not within the scope of ASU 2014-09. 
ASU 2014-09 is effective for the Company on January 1, 2018, with a cumulative-effect adjustment, and will not 
have a significant impact on the financial statements.

2. ACQUISITIONS

Acquisitions are an integral part of the Company’s growth strategy. All acquisitions were accounted for using 
the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities were recorded at 
their fair values at the acquisition date. The excess of the purchase price over the estimated fair value of the net 
assets for tax-free acquisitions was recorded as goodwill, none of which is deductible for tax purposes. The excess 
of the purchase price over the estimated fair value of the net assets for taxable acquisitions was also recorded as 
goodwill, and is deductible for tax purposes. The identified core deposit intangibles for each acquisition are being 
amortized using a non-pro rata basis over an estimated life of 10 to 15 years. The results of operations for each 
acquisition have been included in the Company’s consolidated financial results beginning on the respective 
acquisition date.

86

The measurement period for the Company to determine the fair values of acquired identifiable assets and 

assumed liabilities will end at the earlier of (1) twelve months from the date of the acquisition or (2) as soon as the 
Company receives the information it was seeking about facts and circumstances that existed as of the acquisition 
date or learns that more information is not obtainable. The following acquisitions were completed on the dates 
indicated:

2016 Acquisition

Acquisition of Tradition Bancshares, Inc. — On January 1, 2016, the Company completed the acquisition of 

Tradition Bancshares, Inc. (“Tradition”) and its wholly-owned subsidiary Tradition Bank, headquartered in Houston, 
Texas. Tradition Bank operated 7 banking offices in the Houston, Texas area, including its main office in Bellaire, 3 
banking centers in Katy and 1 banking center in The Woodlands. The acquisition was not considered significant to 
the Company’s financial statements and therefore pro forma financial data and related disclosures are not included.

The Company acquired loans and deposits with fair values of $239.7 million and $489.7 million, respectively, 

at acquisition date. Under the terms of the definitive agreement, Bancshares issued 679,528 shares of its common 
stock plus $39.0 million in cash for all outstanding shares of Tradition capital stock, for total merger consideration 
of $71.5 million, based on Bancshares’ closing stock price of $47.86 on December 31, 2015. During 2016, the 
Company recognized goodwill of $32.0 million, which is calculated as the excess of both the consideration 
exchanged and liabilities assumed as compared to the fair value of identifiable assets acquired, none of which is 
expected to be deductible for tax purposes. Additionally, the Company recognized $5.6 million of core deposit 
intangibles during 2016.

Merger-Related Expenses: The Company did not incur merger-related expenses during 2017. During 2016, 
the Company incurred $670 thousand of pre-tax merger-related expenses attributable to the Tradition acquisition. 
The merger-related expenses are reflected on the Company’s income statement for the applicable periods and are 
reported primarily in the categories of salaries and benefits, data processing and travel and development. There were 
no other merger-related costs incurred during 2016.

Acquired Loans

Acquired loans were preliminarily recorded at fair value based on a discounted cash flow valuation 

methodology that considers, among other things, interest rates, projected default rates, loss given default and 
recovery rates, with no carryover of any existing allowance for credit losses from the acquisition completed during 
2016. During the valuation process, the Company identified PCI and Non-PCI loans in the acquired loan portfolios. 
PCI loan identification considers the following factors: payment history and past due status, debt service coverage, 
loan grading, collateral values and other factors that may indicate deterioration of credit quality since origination. 
Non-PCI loan identification considers the following factors: account types, remaining terms, annual interest rates or 
coupons, current market rates, interest types, past delinquencies, timing of principal and interest payments, loan to 
value ratios, loss exposures and remaining balances. Accretion of purchased discounts on PCI loans will be based on 
estimated future cash flows, regardless of contractual maturities. Accretion of purchased discounts on Non-PCI 
loans will be recognized on a level-yield basis based on contractual maturity of individual loans.

PCI Loans. The carrying amount of PCI loans included in the consolidated balance sheets and the related 
outstanding balances at December 31, 2017 and 2016 are presented in the table below. The outstanding balance 
represents the total amount owed as of December 31, 2017 and 2016.

Income recognition on PCI loans is subject to the Company’s ability to reasonably estimate both the timing 
and amount of future cash flows. PCI loans for which the Company is accruing interest income are not considered 
non-performing or impaired. The non-accretable difference represents contractual principal and interest the 
Company does not expect to collect. 

Non-PCI Loans. The carrying amount of Non-PCI loans included in the consolidated balance sheets and the 

related outstanding balances at December 31, 2017 and 2016 are presented in the table below. The outstanding 
balance represents the total amount owed as of December 31, 2017 and 2016.

Management performs an evaluation annually and more frequently if a triggering event occurs, of whether any 

impairment of the goodwill and other intangibles has occurred. If any such impairment is determined, a write down 
is recorded. As of December 31, 2017, there was no impairment recorded on goodwill and core deposit intangibles.

Core deposit intangibles are being amortized on a non-pro rata basis over their estimated lives, which the 
Company believes is between 10 and 15 years. The estimated aggregate future amortization expense for core deposit 
intangibles remaining as of December 31, 2017 is as follows (dollars in thousands):

 Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more 

frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is 
evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI 
analysis. Investment securities classified as available for sale or held to maturity are evaluated for OTTI under 
Financial Accounting Standards Board (“FASB”): ASC Topic 320, “Investments—Debt and Equity Securities.”

In determining OTTI, management considers many factors, including: (1) the length of time and the extent to 

which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, 
(3) whether the market decline was affected by macroeconomic conditions and (4) whether the entity has the intent 
to sell the debt security or more likely than not will be required to sell the debt security before its anticipated 
recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity 
and judgment and is based on the information available to management at the time of such determination.

When OTTI occurs, the amount of the other-than-temporary impairment recognized in earnings depends on 

whether an entity intends to sell the security or more likely than not will be required to sell the security before 
recovery of its amortized cost basis less any current-period credit loss.

Management has the ability and intent to hold the securities classified as held-to-maturity until they mature, at 

which time the Company will receive full value for the securities. Furthermore, as of December 31, 2017, 
management does not have the intent to sell any of the securities classified as available for sale before a recovery of 
cost. In addition, management believes it is more likely than not that the Company will not be required to sell any of 
its investment securities before a recovery of cost. The unrealized losses are largely due to increases in market 
interest rates over the yields available at the time the underlying securities were purchased. The fair value is 
expected to recover as the securities approach their maturity date or repricing date or if market yields for such 
investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. 
Accordingly, as of December 31, 2017, management believes any impairment in the Company’s securities is 
temporary and no impairment loss has been realized in the Company’s consolidated statements of income.

Securities with unrealized losses segregated by length of time such securities have been in a continuous loss 

position were as follows:

The Company recorded a gain on sale of securities of $3.3 million for the year ended December 31, 2017. The 
gain resulted from the sale of seven mortgage-backed securities with a total book value of $77.6 million. Under ASC 
Topic 320 “Investments – Debt and Equity Securities,” selling a debt security after 85% of the principal outstanding 
has been collected is considered the equivalent to holding the security to maturity. The Company sold these 
securities, which had paid down over 85% of their principal, because they no longer represented an efficient 
investment due to the safekeeping and administrative cost required to maintain them. The Company recorded no 
gain or loss on sale of securities for the years ended December 31, 2016 and 2015.

At December 31, 2017 and 2016, the Company did not own securities of any one issuer (other than the 

U.S. government and its agencies) for which aggregate adjusted cost exceeded 10% of the consolidated 
shareholders’ equity at such respective dates.

Securities with an amortized cost of $5.94 billion and $5.64 billion and a fair value of $5.84 billion and $5.51 

billion at December 31, 2017 and 2016, respectively, were pledged to collateralize public deposits and for other 
purposes required or permitted by law.

Loan Origination/Risk Management. The Company has certain lending policies and procedures in place that 
are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these 
policies and procedures on a regular basis. A reporting system supplements the review process by providing 
management with frequent reports related to loan production, loan quality, concentrations of credit, loan 
delinquencies and non-performing and potential problem loans. Diversification in the loan portfolio is a means of 
managing risk associated with fluctuations in economic conditions. Loans to borrowers with aggregate debt 
relationships over $1.0 million and below $3.5 million are evaluated and acted upon on a daily basis by two of the 
company-wide loan concurrence officers. Loans to borrowers with aggregate debt relationships above $3.5 million 
are evaluated and acted upon by an officers’ loan committee that meets weekly. In addition to the officers’ loan 
committee evaluation, loans to borrowers with aggregate debt relationships from $25.0 million to $50.0 million are 
evaluated and acted upon by the directors’ loan committee which consists of three directors of the Bank and meets 
as necessary. Loans to borrowers with aggregate debt relationships over $50.0 million are evaluated and acted upon 
by the Bank’s Board of Directors either at a regularly scheduled monthly board meeting or by teleconference or 
written consent.

The Company maintains an independent loan review department that reviews and validates the credit risk 

program on a periodic basis. Results of these reviews are presented to management. The loan review process 
complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, 
as well as the Company’s policies and procedures.

(i) Commercial and Industrial Loans. In nearly all cases, the Company’s commercial loans are made in the 

Company’s market areas and are underwritten on the basis of the borrower’s ability to service the debt from income. 
As a general practice, the Company takes as collateral a lien on any available real estate, equipment or other assets 
owned by the borrower and obtains a personal guaranty of the borrower or principal. Working capital loans are 
primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets. In 
general, commercial loans involve more credit risk than residential mortgage loans and commercial mortgage loans 
and, therefore, usually yield a higher return. The increased risk in commercial loans is due to the type of collateral 
securing these loans as well as the expectation that commercial loans generally will be serviced principally from the 
operations of the business, and those operations may not be successful. Historical trends have shown these types of 
loans to have higher delinquencies than mortgage loans. As a result of these additional complexities, variables and 
risks, commercial loans require more thorough underwriting and servicing than other types of loans.

(ii) Commercial Real Estate. The Company makes commercial real estate loans collateralized by owner-
occupied and nonowner-occupied real estate to finance the purchase of real estate. The Company’s commercial real 
estate loans are collateralized by first liens on real estate, typically have variable interest rates (or five year or less 
fixed rates) and amortize over a 15-to 20-year period. Payments on loans secured by nonowner-occupied properties 
are often dependent on the successful operation or management of the properties. Accordingly, repayment of these 
loans may be subject to adverse conditions in the real estate market or the economy to a greater extent than other 
types of loans. The Company seeks to minimize these risks in a variety of ways, including giving careful 
consideration to the property’s operating history, future operating projections, current and projected occupancy, 
location and physical condition in connection with underwriting these loans. The underwriting analysis also includes 
credit verification, analysis of global cash flow, appraisals and a review of the financial condition of the borrower. 
At December 31, 2017, approximately 46.0% of the outstanding principal balance of the Company’s commercial 
real estate loans were secured by owner-occupied properties.

(iii) 1-4 Family Residential Loans. The Company’s lending activities also include the origination of 1-

4 family residential mortgage loans (including home equity loans) collateralized by owner-occupied residential 
properties located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio 
products which generally are amortized over five to 25 years. Loans collateralized by 1-4 family residential real 
estate generally have been originated in amounts of no more than 89% of appraised value or have mortgage 
insurance. The Company requires mortgage title insurance and hazard insurance. The Company retains these 
portfolio loans for its own account rather than selling them into the secondary market. By doing so, the Company 
incurs interest rate risk as well as the risks associated with nonpayments on such loans. The Company’s Home Loan 
Center offers a variety of mortgage loan products which are generally amortized over 30 years, including FHA and 
VA loans. The Company sells the loans originated by the Home Loan Center into the secondary market.

93

(iv) Construction, Land Development and Other Land Loans. The Company makes loans to finance the 

construction of residential and, to a lesser extent, nonresidential properties. Construction loans generally are 
collateralized by first liens on real estate and have floating interest rates. The Company conducts periodic 
inspections, either directly or through an agent, prior to approval of periodic draws on these loans. Underwriting 
guidelines similar to those described above are also used in the Company’s construction lending activities. 
Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of 
a project under construction, and the project is of uncertain value prior to its completion. Because of uncertainties 
inherent in estimating construction costs, the market value of the completed project and the effects of governmental 
regulation on real property, it can be difficult to accurately evaluate the total funds required to complete a project 
and the related loan to value ratio. As a result of these uncertainties, construction lending often involves the 
disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project rather 
than the ability of a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a project prior 
to completion, the Company may not be able to recover all of the unpaid portion of the loan. In addition, the 
Company may be required to fund additional amounts to complete a project and may have to hold the property for 
an indeterminate period of time. Although the Company has underwriting procedures designed to identify what it 
believes to be acceptable levels of risks in construction lending, these procedures may not prevent losses from the 
risks described above.

(v) Agriculture Loans. The Company provides agriculture loans for short-term beef and crop production, 
including rice, cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company 
evaluates agriculture borrowers primarily based on their historical profitability, level of experience in their particular 
agriculture industry, overall financial capacity and the availability of secondary collateral to withstand economic and 
natural variations common to the industry. Because agriculture loans present a higher level of risk associated with 
events caused by nature, the Company routinely makes on-site visits and inspections in order to identify and monitor 
such risks.

(vi) Consumer Loans. Consumer loans made by the Company include direct “A”-credit automobile loans, 
recreational vehicle loans, boat loans, home improvement loans, personal loans (collateralized and uncollateralized), 
credit cards and deposit account collateralized loans. The terms of these loans typically range from 12 to 180 months 
and vary based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do 
real estate secured loans, particularly in the case of consumer loans that are unsecured or collateralized by rapidly 
depreciating assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may 
not provide an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does 
not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In 
addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more 
likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of 
various federal and state laws may limit the amount which can be recovered on such loans.

Concentrations of Credit. Most of the Company’s lending activity occurs within the states of Texas and 
Oklahoma. Commercial real estate loans, 1-4 family residential loans and construction, land development and other 
land loans make up 75.2% of the Company’s total loan portfolio at December 31, 2017.  As of December 31, 2017 
and 2016, there were no concentrations of loans related to any single industry in excess of 10% of total loans.

Foreign Loans. The Company has U.S. dollar-denominated loans and commitments to borrowers in Mexico. 

The outstanding balance of these loans and the unfunded amounts available under these commitments was not 
significant at December 31, 2017 or 2016.

Related Party Loans. As of December 31, 2017 and 2016, loans outstanding to directors, officers and their 
affiliates totaled $2.7 million and $4.5 million, respectively. All transactions between the Company and such related 
parties are conducted in the ordinary course of business and made on the same terms and conditions as similar 
transactions with unaffiliated persons.

An analysis of activity with respect to these related-party loans is as follows:

Nonperforming Assets and Nonaccrual and Past Due Loans. The Company has several procedures in place to 
assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines 
to be followed by its officers, and the Company also monitors its delinquency levels for any negative or adverse 
trends. Nevertheless, the Company’s loan portfolio could become subject to increasing pressures from deteriorating 
borrower credit due to general economic conditions.

The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of 
principal or interest is delinquent for 90 days, or earlier in some cases, unless the loan is in the process of collection 
and the underlying collateral fully supports the carrying value of the loan.

The Company requires appraisals on loans collateralized by real estate. With respect to potential problem 
loans, an evaluation of the borrower’s overall financial condition is made to determine the need, if any, for possible 
writedowns or appropriate additions to the allowance for credit losses.

Includes troubled debt restructurings of $53 thousand, $97 thousand, $681 thousand, $ 911 thousand and $1.4 
million for the years ended December 31, 2017, 2016, 2015, 2014 and 2013, respectively.

The Company had $37.5 million in nonperforming assets at December 31, 2017 compared with $48.3 million 
at December 31, 2016 and $43.5 million at December 31, 2015. Nonperforming assets were 0.37% of total loans and 
other real estate at December 31, 2017 compared with 0.50% of total loans and other real estate at December 31, 
2016 and 0.46% of total loans and other real estate at December 31, 2015. The nonperforming assets consisted of 99 
separate credits or other real estate properties at December 31, 2017, compared with 158 at December 31, 2016 and 
147 at December 31, 2015.

If interest on nonaccrual loans had been accrued under the original loan terms, approximately $2.7 million, 
$3.2 million, and $3.9 million would have been recorded as income for the years ended December 31, 2017, 2016 
and 2015, respectively.

Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable 
the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan 
agreement, including scheduled principal and interest payments. Impairment is evaluated in total for smaller-balance 
loans of a similar nature and on an individual loan basis for other loans. If a loan is impaired, a specific valuation 
allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash 
flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the 
collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal 
amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions 
thereof, are charged off when deemed uncollectible.

Credit Quality Indicators. As part of the on-going monitoring of the credit quality of the Company’s loan 
portfolio and methodology for calculating the allowance for credit losses, management assigns and tracks loan 
grades to be used as credit quality indicators.

The following is a general description of the loan grades used:

Grade 1—Credits in this category have risk potential that is virtually nonexistent. These loans may be secured 

by insured certificates of deposit, insured savings accounts, U.S. Government securities and highly rated municipal 
bonds.

Grade 2—Credits in this category are of the highest quality. These borrowers represent top-rated companies 

and individuals with unquestionable financial standing with excellent global cash flow coverage, net worth, liquidity 
and collateral coverage. 

Grade 3—Credits in this category are not immune from risk but are well protected by the collateral and 
paying capacity of the borrower. These loans may exhibit a minor unfavorable credit factor, but the overall credit is 
sufficiently strong to minimize the possibility of loss.

Grade 4—Credits in this category are considered to be of acceptable credit quality with moderately greater 
risk than Grade 3 and receiving closer monitoring. Loans in this category have sources of repayment that remain 
sufficient to preclude a larger than normal probability of default and secondary sources are likewise currently of 
sufficient quantity, quality, and liquidity to protect the Company against loss of principal and interest. These 
borrowers have specific risk factors, but the overall strength of the credit is acceptable based on other mitigating 
credit and/or collateral factors and can repay the debt in the normal course of business.

Grade 5—Credits in this category constitute an undue and unwarranted credit risk; however, the factors do 

not rise to a level of substandard. These credits have potential weaknesses and/or declining trends that, if not 
corrected, could expose the Bank to risk at a future date. These loans are monitored on the Bank’s internally 
generated watch list and evaluated on a quarterly basis.

Grade 6—Credits in this category are considered “substandard” but “non-impaired” loans in accordance with 

regulatory guidelines. Loans in this category have well-defined weakness that, if not corrected, could make default 
of principal and interest possible. Loans in this category are still accruing interest and may be dependent upon 
secondary sources of repayment and/or collateral liquidation.

Grade 7—Credits in this category are deemed “substandard” and “impaired” pursuant to regulatory 

guidelines. As such, the Bank has determined that it is probable that less than 100% of the contractual principal and 
interest will be collected. These loans are individually evaluated for a specific reserve and will typically have the 
accrual of interest stopped.

Grade 8—Credits in this category include “doubtful” loans in accordance with regulatory guidance. Such 

loans are no longer accruing interest and factors indicate a loss is imminent. These loans are also deemed 
“impaired.” While a specific reserve may be in place while the loan and collateral is being evaluated these loans are 
typically charged down to an amount the Bank estimates is collectible.

Grade 9—Credits in this category are deemed a “loss” in accordance with regulatory guidelines and have 

been charged off or charged down. The Bank may continue collection efforts and may have partial recovery in the 
future.

The following table presents risk grades and PCI loans by category of loan at December 31, 2017. Impaired 

loans include loans in risk grades 7, 8 and 9, as well as any PCI loan that has a specific reserve allocated to it.

Allowance for Credit Losses. The allowance for credit losses is a valuation established through charges to 
earnings in the form of a provision for credit losses. Management has established an allowance for credit losses 
which it believes is adequate as of December 31, 2017 for estimated losses in the Company’s loan portfolio. The 
amount of the allowance for credit losses is affected by the following: (1) charge-offs of loans that occur when loans 
are deemed uncollectible and decrease the allowance, (2) recoveries on loans previously charged off that increase 
the allowance and (3) provisions for credit losses charged to earnings that increase the allowance. Based on an 
evaluation of the loan portfolio and consideration of the factors listed below, management presents a quarterly 
review of the allowance for credit losses to the Bank’s Board of Directors, indicating any change in the allowance 
since the last review and any recommendations as to adjustments in the allowance. Although management believes it 
uses the best information available to make determinations with respect to the allowance for credit losses, future 
adjustments may be necessary if economic conditions or the borrower’s performance differ from the assumptions 
used in making the initial determinations.

The Company’s allowance for credit losses consists of two components: (1) a specific valuation allowance 
based on probable losses on specifically identified loans and (2) a general valuation allowance based on historical 
loan loss experience, general economic conditions and other qualitative risk factors both internal and external to the 
Company.

In setting the specific valuation allowance, the Company follows a loan review program to evaluate the credit 
risk in the total loan portfolio and assigns risk grades to each loan. Through this loan review process, the Company 
maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess 
the overall quality of the loan portfolio and the adequacy of the allowance for credit losses. All loans that have been 
identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required. 
For certain impaired loans, the Company allocates a specific loan loss reserve primarily based on the value of the 
collateral securing the impaired loan in accordance with ASC Topic 310-10,“Receivables.” The specific reserves 
are determined on an individual loan basis. Loans for which specific reserves are provided are excluded from the 
general valuation allowance described below.

In connection with this review of the loan portfolio, the Company considers risk elements attributable to 

particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include:

(cid:129)

(cid:129)

(cid:129)

for 1-4 family residential mortgage loans, the borrower’s ability to repay the loan, including a 
consideration of the debt to income ratio and employment and income stability, the loan to value ratio, 
and the age, condition and marketability of collateral;

for commercial real estate loans and multifamily residential loans, the debt service coverage ratio 
(income from the property in excess of operating expenses compared to loan payment requirements), 
operating results of the owner in the case of owner-occupied properties, the loan to value ratio, the age 
and condition of the collateral and the volatility of income, property value and future operating results 
typical of properties of that type;

for construction, land development and other land loans, the perceived feasibility of the project 
including the ability to sell developed lots or improvements constructed for resale or the ability to lease 
property constructed for lease, the quality and nature of contracts for presale or prelease, if any, 
experience and ability of the developer and loan to value ratio;

for commercial and industrial loans, the operating results of the commercial, industrial or professional 
enterprise, the borrower’s business, professional and financial ability and expertise, the specific risks 
and volatility of income and operating results typical for businesses in that category and the value, 
nature and marketability of collateral;

for agricultural real estate loans, the experience and financial capability of the borrower, projected debt 
service coverage of the operations of the borrower and loan to value ratio; and

for non-real estate agricultural loans, the operating results, experience and financial capability of the 
borrower, historical and expected market conditions and the value, nature and marketability of 
collateral.

In addition, for each category, the Company considers secondary sources of income and the financial strength 

and credit history of the borrower and any guarantors.

In determining the amount of the general valuation allowance, management considers factors such as 
historical loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the 
Company’s loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of 
collateral, the evaluation of the Company’s loan portfolio through its internal loan review process, general economic 
conditions and other qualitative risk factors both internal and external to the Company and other relevant factors in 
accordance with ASC Topic 450, “Contingencies.” Based on a review of these factors for each loan type, the 
Company applies an estimated percentage to the outstanding balance of each loan type, excluding any loan that has a 
specific reserve allocated to it. Allocation of a portion of the allowance to one category of loans does not preclude its 
availability to absorb losses in other categories. The Company uses this information to establish the amount of the 
general valuation allowance. 

A change in the allowance for credit losses can be attributable to several factors, most notably (1) specific 
reserves identified for impaired loans, (2) historical credit loss information, (3) changes in environmental factors and 
(4) growth in the balance of legacy loans and the renewal or substantial modification of acquired loans (Non-PCI 
and PCI loans as discussed in Note 2) into the loan portfolio subject to the allowance methodology.

Changes in the Company’s asset quality are reflected in the allowance in several ways. Specific reserves that 
are calculated on a loan-by-loan basis and the qualitative assessment of all other loans reflect current changes in the 
credit quality of the loan portfolio. Historical credit losses, on the other hand, are based on a three-year look back 
period, which are then applied to estimate current credit losses inherent in the loan portfolio. A deterioration in the 
credit quality of the loan portfolio in the current period would increase the historical credit loss factor to be applied 
in future periods, just as an improvement in credit quality would decrease the historical credit loss factor.

102

The allowance for credit losses is further determined by the size of the loan portfolio subject to the allowance 

methodology and environmental factors that include Company-specific risk indicators and general economic 
conditions, both of which are constantly changing. The Company evaluates the economic and portfolio-specific 
factors on a quarterly basis to determine a qualitative component of the general valuation allowance. The factors 
include economic metrics, business conditions, delinquency trends, credit concentrations, nature and volume of the 
portfolio and other adjustments for items not covered by specific reserves and historical loss experience. 
Management’s assessment of qualitative factors is a statistically based approach to determine the inherent probable 
loss associated with such factors. Based on the Company’s actual historical loan loss experience relative to 
economic and loan portfolio-specific factors at the time the losses occurred, management is able to identify the 
probabilities of default and loss severity based on current economic conditions. The correlation of historical loss 
experience with current economic conditions provides an estimate of inherent and probable losses that has not been 
previously factored into the general valuation allowance by the determination of specific reserves and recent 
historical losses. Additionally, the Company considers qualitative factors not easily quantified and the possibility of 
model imprecision.

Utilizing the aggregation of specific reserves, historical loss experience and a qualitative component, 

management is able to determine the valuation allowance to reflect the full inherent probable loss. 

Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of 

inherent credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding 
allowance for credit losses is recorded for these loans at acquisition. When a fair-valued acquired loan is renewed at 
its maturity date, the loan is re-categorized and is subject to the allowance methodology. When a fair-valued 
acquired loan is modified after acquisition, the loan is independently evaluated subsequent to the modification 
decision to determine whether the modification was, substantial, and therefore, requires that the loan be re-
categorized as an acquired legacy loan. The determination is based on a discounted cash-flow analysis. Generally, 
when a change in discounted cash-flow of greater than 10% is identified, the fair-valued acquired loan becomes re-
categorized and is evaluated at the time of renewal or modification in accordance with the Company’s allowance for 
credit losses methodology described above.

Non-PCI loans that were not deemed impaired subsequent to the acquisition date are considered non-impaired 

and are evaluated as part of the general valuation allowance. Non-PCI loans that have not become impaired 
subsequent to acquisition are segregated into a pool for each acquisition for allowance calculation purposes. For 
each pool, the Company estimates a hypothetical allowance for credit losses also referred to as an “indicated 
reserve” that is calculated in accordance with GAAP requirements. The Company uses the acquired bank’s past loss 
history adjusted for qualitative factors to establish the indicated reserve. The indicated reserve for each pool of Non-
PCI loans is compared with the remaining discount for the respective pool to test for credit quality deterioration and 
the possible need for a loan loss provision. To the extent the remaining discount of the pool is greater than the 
indicated reserve, no additional allowance is necessary. If the remaining discount of the pool is less than the 
indicated reserve, the difference results in an increase to the allowance recorded through a provision for credit 
losses.

Non-PCI loans that have deteriorated to an impaired status subsequent to acquisition are evaluated for a 

specific reserve on a quarterly basis which, when identified, is added to the allowance for credit losses. The 
Company reviews impaired Non-PCI loans on a loan-by-loan basis and determines the specific reserve based on the 
difference between the recorded investment in the loan and one of three factors: expected future cash flows, 
observable market price or fair value of the collateral. Because essentially all of the Company’s impaired Non-PCI 
loans have been collateral-dependent, the amount of the specific reserve historically has been determined by 
comparing the fair value of the collateral securing the Non-PCI loan with the recorded investment in such loan. In 
the future, the Company will continue to analyze impaired Non-PCI loans on a loan-by-loan basis and may use an 
alternative measurement method to determine the specific reserve, as appropriate and in accordance with applicable 
accounting standards.

103

PCI loans are individually monitored on a quarterly basis to assess for deterioration subsequent to acquisition 

and are only subject to the Company’s allowance methodology when a deterioration in projected cash flows is 
identified. In the event that a deterioration in cash flows is identified, an additional provision for credit losses is 
made. PCI loans were recorded at their acquisition date fair values, which were based on expected cash flows and 
included estimates of expected future credit losses. The Company’s estimates of loan fair values at the acquisition 
date may be adjusted for a period of up to one year as the Company continues to evaluate its estimate of expected 
future cash flows at the acquisition date. If the Company determines that losses arose after the acquisition date, the 
additional losses will be reflected as a provision for credit losses. An allowance for credit losses is not calculated for 
PCI loans that have not experienced deterioration subsequent to the acquisition date.

At December 31, 2017, the allowance for credit losses totaled $84.0 million or 0.84% of total loans, including 
acquired loans with discounts. At December 31, 2016, the allowance for credit losses totaled $85.3 million or 0.89% 
of total loans, and at December 31, 2015, the allowance aggregated $81.4 million or 0.86% of total loans, both 
including acquired loans with discounts. The allowance for credit losses totaled $84.0 million at December 31, 2017 
compared with $85.3 million at December 31, 2016, a decrease of $1.3 million or 1.5%.

The following tables detail the recorded investment in loans, excluding $31.4 million and $27.0 million of 
residential mortgage loans held for sale, and activity in the allowance for credit losses by category of loan for the 
years ended December 31, 2017 and 2016, respectively.

Troubled Debt Restructurings. The restructuring of a loan is considered a “troubled debt restructuring” if both 
(1) the borrower is experiencing financial difficulties and (2) the creditor has granted a concession. Concessions may 
include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization 
schedules and other actions intended to minimize potential losses. Under ASC topic 310-40 “Receivables—Troubled 
Debt Restructurings by Creditors,” the Company evaluates all loan modifications for identification as troubled debt 
restructurings. At December 31, 2017 and 2016, the Company had $53 thousand and $97 thousand, respectively, in 
outstanding troubled debt restructurings.  The following table presents information regarding the recorded 
investment at December 31, 2017 and 2016 of loans modified in a troubled debt restructuring during the years ended 
December 31, 2017 and 2016:

Total

For the year ended December 31, 2017, the Company added 3 loans totaling $8.7 million as new troubled debt 

restructurings, none of which remained outstanding at December 31, 2017. During the year ended December 31, 
2017, the Company fully charged off two loans with a recorded investment of $4.3 million at the time of charge off. 
These two loans were modified as troubled debt restructurings during the first quarter of 2017 and had defaulted in 
payment prior to the charge off. As of December 31, 2017 there have been no other defaults on any loans that were 
modified as troubled debt restructurings during the preceding twelve months. Default is determined at 90 or more 
days past due. There were no charge-offs related to restructured loans recognized during the year ended December 
31, 2016. The modifications primarily related to extending the amortization periods of the loans, which includes 
loans modified during bankruptcy. The Company did not grant principal reductions on any restructured loans. These 
modifications did not have a material impact on the Company’s determination of the allowance for credit losses.

7. FAIR VALUE

The Company uses fair value measurements to record fair value adjustments to certain assets and to determine 

fair value disclosures. Fair values represent the estimated price that would be received from selling an asset or paid 
to transfer a liability, otherwise known as an “exit price.” Securities available for sale are recorded at fair value on a 
recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on 
a nonrecurring basis. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-
market accounting or write downs of individual assets. ASC Topic 820, “Fair Value Measurements and 
Disclosures” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in 
active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value 
hierarchy is as follows:

Fair Value Hierarchy

The Company groups financial assets and financial liabilities measured at fair value in three levels, based on 
the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair 
value. These levels are:

(cid:129)

(cid:129)

(cid:129)

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Other significant observable inputs (including quoted prices in active markets for similar 
assets or liabilities) or other inputs that are observable or can be corroborated by observable market data 
for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant 
to the fair value of the assets or liabilities.

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that 
liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a 
principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that 
are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques 
are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use 
in pricing an asset or liability.

The fair value disclosures below represent the Company’s estimates based on relevant market information and 
information about the financial instruments. Fair value estimates are based on judgments regarding current economic 
conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature 
and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. 
Changes in the above methodologies and assumptions could significantly affect the estimates.

The following tables present fair values for assets measured at fair value on a recurring basis:

Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not 

measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for 
example, when there is evidence of impairment). These instruments include other real estate owned, repossessed 
assets, held to maturity debt securities, loans held for sale, and impaired loans. For the year ended December 31, 
2017, the Company had additions to other real estate owned of $1.6 million, of which $923 thousand were 
outstanding as of December 31, 2017. For the year ended December 31, 2017, the Company had additions to 
impaired loans of $20.9 million, of which $17.6 million were outstanding as of December 31, 2017. The remaining 
financial assets and liabilities measured at fair value on a non-recurring basis that were recorded in 2017 and 
remained outstanding at December 31, 2017 were not significant.

The following tables summarize the carrying values and estimated fair values of certain financial instruments

Entities may choose to measure eligible financial instruments at fair value at specified election dates. The fair 

value measurement option (1) may be applied instrument by instrument, with certain exceptions, (2) is generally 
irrevocable and (3) is applied only to entire instruments and not to portions of instruments. Unrealized gains and 
losses on items for which the fair value measurement option has been elected must be reported in earnings at each 
subsequent reporting date. During the reported periods, the Company had no financial instruments measured at fair 
value under the fair value measurement option.

The fair value estimates presented herein are based on pertinent information available to management as of the 

dates indicated. Although management is not aware of any factors that would significantly affect the estimated fair 
value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements 
since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented 
herein.

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value, 
non-financial assets and non-financial liabilities, and for estimating fair value for financial instruments not recorded 
at fair value:

Cash and due from banks—For these short-term instruments, the carrying amount is a reasonable estimate 

of fair value. The Company classifies the estimated fair value of these instruments as Level 1.

Federal funds sold—For these short-term instruments, the carrying amount is a reasonable estimate of fair 

value. The Company classifies the estimated fair value of these instruments as Level 1.

Securities —Fair value measurements based upon quoted prices are considered Level 1 inputs. Level 1 
securities consist of U.S. Treasury securities and certain equity securities which are included in the available for sale 
portfolio. For all other available for sale and held to maturity securities, if quoted prices are not available, fair values 
are measured using Level 2 inputs. For these securities, the Company generally obtains fair value measurements 
from an independent pricing service. The fair value measurements consider observable data that may include dealer 
quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market 
consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. The 
Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing 
methodologies, for reasonableness.

Securities available for sale are recorded at fair value on a recurring basis.

Loans held for sale—Loans held for sale are carried at the lower of cost or estimated fair value. Fair value for 

consumer mortgages held for sale is based on commitments on hand from investors or prevailing market prices. As 
such, the Company classifies loans subjected to nonrecurring fair value adjustments as Level 2.

Loans held for investment—The Company does not record loans at fair value on a recurring basis. As such, 

valuation techniques discussed herein for loans are primarily for estimating fair value disclosures. However, from 
time to time, the Company records nonrecurring fair value adjustments to impaired loans to reflect (1) partial write 
downs that are based on the observable market price or current appraised value of the collateral, or (2) the full 
charge-off of the loan carrying value. Where appraisals are not available, estimated cash flows are discounted using 
a rate commensurate with the credit risk associated with those cash flows. Assumptions regarding credit risk, cash 
flows and discount rates are judgmentally determined using available market information and specific borrower 
information.

The estimated fair value approximates carrying value for variable-rate loans that reprice frequently and with 

no significant change in credit risk. The fair value of fixed-rate loans and variable-rate loans which reprice on an 
infrequent basis is estimated by discounting future cash flows using the current interest rates at which similar loans 
with similar terms would be made to borrowers of similar credit quality. An overall valuation adjustment is made for 
specific credit risks as well as general portfolio credit risk. The Company classifies the estimated fair value of loans 
held for investment as Level 3.

Other real estate owned—Other real estate owned is primarily foreclosed properties securing residential 

loans and commercial real estate. Foreclosed assets are adjusted to fair value less estimated costs to sell upon 
transfer of the loans to other real estate owned. Subsequently, these assets are carried at the lower of carrying value 
or fair value less estimated costs to sell. Other real estate carried at fair value based on an observable market price or 
a current appraised value is classified by the Company as Level 2. When management determines that the fair value 
of other real estate requires additional adjustments, either as a result of a non-current appraisal or when there is no 
observable market price, the Company classifies the other real estate as Level 3.

Deposits—The fair value of demand deposits, savings accounts and certain money market deposits is the 
amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated 
using the rates currently offered for deposits of similar remaining maturities. Deposits fair value measurements 
utilize Level 2 inputs.

Other borrowings—Rates currently available to the Company for debt with similar terms and remaining 
maturities are used to estimate the fair value of other borrowings using a discounted cash flows methodology and are 
measured utilizing Level 2 inputs.

Securities sold under repurchase agreements—The fair value of securities sold under repurchase 

agreements is the amount payable on demand at the reporting date and are measured utilizing Level 2 inputs.

Off-balance sheet financial instruments—The fair value of commitments to extend credit and standby 
letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the 
remaining terms of the agreement and the present creditworthiness of the counterparties. The Company has 
reviewed the unfunded portion of commitments to extend credit as well as standby and other letters of credit, and 
has determined that the fair value of such financial instruments is not material. The Company classifies the 
estimated fair value of credit-related financial instruments as Level 3.

borrowings and used to manage liquidity as needed. Maturing advances are replaced by drawing on available cash, 
making additional borrowings or through increased customer deposits. At December 31, 2017, the Company had 
total funds of $5.77 billion available under this agreement, of which a total amount of $505.2 million was 
outstanding at December 31, 2017. FHLB advances were $500.0 million at December 31, 2017, with a weighted 
average interest rate of 1.21%. Long-term notes payable were $5.2 million at December 31, 2017, with a weighted 
average interest rate of 5.70%. The maturity dates on the FHLB notes payable range from the years 2018 to 2027 
and have interest rates ranging from 4.51% to 6.10%.

Securities sold under repurchase agreements with Company customers—At December 31, 2017, the 

Company had $324.2 million in securities sold under repurchase agreements compared with $320.4 million at 
December 31, 2016, with average rates paid of 0.39% and 0.29% for the years ended December 31, 2017 and 2016, 
respectively. Repurchase agreements are generally settled on the following business day; however, approximately 
$9.8 million of repurchase agreements outstanding at December 31, 2017 have maturity dates ranging from 6 to 24 
months. All securities sold under agreements to repurchase are collateralized by certain pledged securities.

Income tax expense for 2017 was impacted by the adjustment of deferred tax assets and liabilities related to 

the reduction in the U.S. federal statutory income tax rate to 21% under the Tax Cuts and Jobs Act, which was 
enacted on December 22, 2017. As a result of the new law, which is more fully discussed below, the Company 
recognized a net tax expense totaling $1.4 million, as presented in the table above. During 2017, the Company 
adopted a new accounting standard that requires the income tax effects associated with stock-based compensation to 
be recognized as a component of income tax expense. The Company recognized net tax benefits related to stock-
based compensation totaling $442 thousand in 2017, as presented in the table above. See Note 1 - Significant 
Accounting Policies for additional information related to the accounting for the income tax effects of stock-based 
compensation.

corporate income tax rate of 21%. Deferred taxes as of December 31, 2016 are based on the previously enacted U.S. 
statutory federal corporate income tax rate of 35%.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income 

during the periods in which those temporary differences become deductible. Management considers the scheduled 
reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this 
assessment. Based upon the level of historical taxable income and estimates of future taxable income over the 
periods for which the deferred tax assets are deductible, management believes it is more likely than not the 
Company will realize the benefits of these deductible differences at December 31, 2017. 

Benefits from tax positions are recognized in the financial statements only when it is more likely than not that 

the tax position will be sustained upon examination by the appropriate taxing authority that would have full 
knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is 
measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate 
settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold are 
recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized 
tax positions that no longer meet the more-likely-than-not recognition threshold are derecognized in the first 
subsequent financial reporting period in which that threshold is no longer met. The Company had no tax positions at 
December 31, 2017 or December 31, 2016 that did not meet the more-likely-than not recognition threshold. ASC 
Topic 740 “Income Taxes” also provides guidance on the accounting for and disclosure of unrecognized tax 
benefits, interest and penalties. The Company’s policy for recording interest and penalties associated with audits is 
to record such items as a component of income before taxes. Penalties are recorded in other (gains) losses and 
interest paid or received is recorded in interest expense or interest income, respectively, in the consolidated 
statement of income. As of December 31, 2017 and 2016, the Company has not accrued any interest and penalties 
related to unrecognized tax benefits. The Company has identified its federal tax return and its state tax returns in 
Texas, Oklahoma and Arkansas as “major” tax jurisdictions, as defined. The periods subject to examination for the 
Company’s federal return are the 2014 through 2017 tax years. The Company has assumed to net operating loss

carryforwards, “acquired NOLs”, through its acquisitions. The tax periods of the acquired entities from which these 
acquired NOLs originated are considered open years for purposes of adjusting the amount of the acquired NOLs 
used in the Company’s open years. Net operating loss carryforwards expire in tax years beginning in 2028 through 
2031.

Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act was enacted on December 22, 2017. Among other things, 

the new law (i) establishes a new, flat federal statutory corporate income tax rate of 21%, (ii) eliminates the 
corporate alternative minimum tax and allows the use of any such carryforwards to offset regular tax liability for any 
taxable year, (iii) limits the deduction for net interest expense incurred by U.S. corporations, (iv) allows businesses 
to immediately expense, for tax purposes, the cost of new investments in certain qualified depreciable assets, 
(v) eliminates or reduces certain deductions related to meals and entertainment expenses, (vi) modifies the limitation 
on excessive employee remuneration to eliminate the exception for performance-based compensation and clarifies 
the definition of a covered employee and (vii) limits the deductibility of deposit insurance premiums. The Tax Cuts 
and Jobs Act also significantly changes U.S. tax law related to foreign operations, however, such changes do not 
currently impact the Company. As stated above, as a result of the enactment of the Tax Cuts and Jobs Act on 
December 22, 2017, the Company remeasured its deferred tax assets and liabilities based upon the newly enacted 
U.S. statutory federal corporate income tax rate of 21%, which is the tax rate at which these assets and liabilities are 
expected to reverse in the future.  The Company is still analyzing certain aspects of the new law and refining its 
calculations, which could affect the measurement of these deferred tax assets and liabilities or give rise to new 
deferred tax amounts. The Company recognized a one-time non-cash income tax expense related to the 
remeasurement of its deferred tax assets and liabilities totaling $1.4 million during the year ended December 31, 
2017. 

12. STOCK INCENTIVE PROGRAMS

At December 31, 2017, the Company had two stock-based employee compensation plans with awards 
outstanding. One of these plans has expired and therefore no additional awards may be issued under that plan. The 
Company accounts for stock-based employee compensation plans using the fair value-based method of 
accounting. The Company recognized stock-based compensation expense of $6.9 million, $9.5 million and $11.1 
million for the years ended December 31, 2017, 2016 and 2015, respectively. There was approximately $2.4 million, 
$3.3 million and $3.9 million of income tax benefit recorded for the stock-based compensation expense for the same 
periods, respectively.

In December 2004, Bancshares’ Board of Directors established the Prosperity Bancshares, Inc. 2004 Stock 
Incentive Plan (the “2004 Plan”), which was approved by Bancshares’ shareholders on February 23, 2005. The 2004 
Plan authorized the issuance of up to 1,250,000 shares of common stock upon the exercise of options granted under 
the 2004 Plan or upon the grant or exercise, as the case may be, of other awards granted under the 2004 Plan. The 
2004 Plan provided for grants of incentive and nonqualified stock options to employees and nonqualified stock 
options to directors who are not employees. The 2004 Plan also provided for grants of shares of restricted stock, 
stock appreciation rights, phantom stock awards and performance awards on substantially similar terms. A total of 
191,625 options and 793,218 shares of restricted stock have been granted under the 2004 Plan as of December 31, 
2017. No options granted under the 2004 Plan were outstanding at December 31, 2017. The 2004 Plan has expired 
and therefore no additional shares may be issued under the 2004 Plan.

On February 22, 2012, Bancshares’ Board of Directors adopted the Prosperity Bancshares, Inc. 2012 Stock 
Incentive Plan (the “2012 Plan”), which was approved by Bancshares’ shareholders on April 17, 2012. The 2012 
Plan authorizes the issuance of up to 1,250,000 shares of common stock upon the exercise of options granted under 
the 2012 Plan or pursuant to the grant or exercise, as the case may be, of other awards granted under the 2012 Plan, 
including restricted stock, stock appreciation rights, phantom stock awards and performance awards. A total of 
359,133 shares of restricted stock have been granted under the 2012 Plan as of December 31, 2017.

Stock Options

Stock options are issued at the current market price on the date of the grant, subject to a pre-determined 
vesting period with a contractual term of 10 years. Options assumed in connection with acquisitions have contractual 
terms as established in the original option grant agreements entered into prior to acquisition. The fair value of stock 
options granted is estimated at the date of grant using the Black-Scholes option-pricing model. The Black-Scholes 
pricing model utilizes certain assumptions including expected life of the option, risk free interest rate, volatility and 
dividend yield. Stock-based compensation expense is recognized ratably over the requisite service period for all 
awards. There were no options issued for the years ended December 31, 2017, 2016 and 2015 and the Company had 
no options outstanding at December 31, 2017.

$202 thousand and $931 thousand, respectively. No options vested during the year ended December 31, 2017, as all 
options vested prior to 2017. There were no unvested options forfeited during the years ended December 31, 2017 
and 2016. 

The Company received $148 thousand, $778 thousand and $290 thousand in cash from the exercise of stock 
options during the years ended December 31, 2017, 2016 and 2015, respectively. There was no tax benefit realized 
from exercises of the stock-based compensation arrangements during the years ended December 31, 2017, 2016 and 
2015.

Restricted Stock

The Company has granted shares of restricted stock pursuant to the 2004 and 2012 Plans. These shares of 

restricted stock generally vest over a period of one to five years. The Company accounts for restricted stock grants 
by recording the fair value of the grant as compensation expense over the vesting period. Compensation expense 
related to restricted stock was $6.9 million, $9.5 million and $11.1 million for the years ended December 31, 2017, 
2016 and 2015, respectively.

an employee’s contributions, up to 15% of such employee’s compensation, not to exceed the maximum allowable 
pursuant to the Code and excluding catch-up contributions. Such matching contributions were approximately $4.3 
million, $4.4 million and $4.3 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Off-Balance Sheet Items

In the normal course of business, the Company enters into various transactions, which, in accordance with 

GAAP, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the 
financing needs of its customers. These transactions include commitments to extend credit and standby letters of 
credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts 
recognized in the consolidated balance sheets.

The Company’s commitments associated with outstanding standby letters of credit and commitments to 

extend credit expiring by period as of December 31, 2017 are summarized below.

Standby Letters of Credit. Standby letters of credit are written conditional commitments issued by the 
Company to guarantee the payment by or performance of a customer to a third party. In the event the customer does 
not perform in accordance with the terms of the agreement with the third party, the Company would be required to 
fund the commitment. The maximum potential amount of future payments the Company could be required to make 
is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be 
entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit 
arrangements contain security and debt covenants similar to those contained in loan agreements.

Commitments to Extend Credit. The Company enters into contractual commitments to extend credit, normally 
with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the 
Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the 
time of loan funding. The Company minimizes its exposure to loss under these commitments by subjecting them to 
credit approval and monitoring procedures. Management assesses the credit risk associated with certain 
commitments to extend credit in determining the level of the allowance for credit losses. Since many of the 
commitments are expected to expire without being fully drawn upon, the total commitment amounts disclosed above 
do not necessarily represent future cash funding requirements. 

At December 31, 2017, $225.2 million of commitments to extend credit and standby letters of credit have 

fixed rates ranging from 1.6% to 21.0%.

Litigation—The Company and the Bank are defendants, from time to time, in legal actions arising from 
transactions conducted in the ordinary course of business. After consultations with legal counsel, the Company and 
the Bank believe that the ultimate liability, if any, arising from such actions will not have a material adverse effect 
on their financial statements.

 17. REGULATORY MATTERS

The Company and the Bank are subject to various regulatory capital requirements administered by the federal 

banking agencies. Any institution that fails to meet its minimum capital requirements is subject to actions by 
regulators that could have a direct material effect on the Company’s financial statements. Under the capital 
adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital 
guidelines based on the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory 
accounting practices. The Company’s and the Bank’s capital amounts and the Bank’s classification under the 
regulatory framework for prompt corrective action are also subject to qualitative judgments by the regulators about 
the components, risk weightings and other factors.

The Basel III Capital Rules adopted by the federal regulatory authorities in 2013 substantially revised the risk-

based capital requirements applicable to the Company and the Bank. The Basel III Capital Rules became effective 
for the Company and the Bank on January 1, 2015, subject to a phase-in period for certain provisions. Among other 
things, the Basel III Capital Rules introduced a new capital measure called “Common Equity Tier 1” (“CET1”), 
which is a comparison of the sum of certain equity capital components to total risk-weighted assets, and revised the 
risk-weighting approach of the capital ratios with a more risk-sensitive approach that expanded the risk-weighting 
categories from the previous Basel I derived categories to a much larger and more risk-sensitive number of 
categories, depending on the nature of the assets. 

To meet the capital adequacy requirements, the Company and the Bank must maintain minimum capital 
amounts and ratios of CET1, Tier 1 and Total capital to risk weighted assets, and of Tier 1 capital to adjusted 
quarterly average assets as defined in the regulations. As of December 31, 2017, the Company and the Bank met all 
capital adequacy requirements to which they were subject.

The Basel III Capital Rules require a “capital conservation buffer,” composed entirely of CET1, in addition to 

the minimum risk-weighted asset capital ratios. The implementation of the capital conservation buffer began on 
January 1, 2016 at the 0.625% level and is being phased in over a four-year period (increasing by that amount on 
each subsequent January 1, until it reaches 2.5% on January 1, 2019). The required phase-in buffer during 2017 was 
1.25%.

The CET1, Tier 1 and total capital ratios are calculated by dividing the respective capital amounts by risk 
weighted assets. Risk weighted assets include total assets, excluding goodwill and other intangible assets, allocated 
by risk weight category, and certain off-balance-sheet items. The leverage ratio is calculated by dividing Tier 1 
capital by adjusted quarterly average total assets, excluding goodwill and other intangible assets.

As of December 31, 2017, the most recent notification from the FDIC categorized the Bank as “well 
capitalized” under the regulatory framework for prompt corrective action. There have been no conditions or events 
since that notification which management believes have changed the Bank’s category. To be categorized as well 
capitalized the Bank must maintain minimum CET1 risk-based, Tier 1 risk-based, total risk-based and Tier 1 
leverage ratios as set forth in the table below. 

The following is a summary of the Company’s and the Bank’s capital ratios at December 31, 2017 and 2016:
