Overview 

We  are  headquartered  in  Laredo,  Texas,  with  189  facilities  and  287  ATMs,  provides  banking  services  for 
commercial, consumer and international customers of north, south, central and southeast Texas and the State of Oklahoma. 
We  are  one  of  the  largest  independent  commercial  bank  holding  companies  headquartered  in  Texas.  We,  through  our 
Subsidiary Banks, are in the business of gathering funds from various sources and investing those funds in order to earn a 
return. We, either directly or through a Subsidiary Bank, own one insurance agency, a liquidating subsidiary, a fifty percent 
interest in an investment banking unit that owns a broker/dealer, a controlling interst in four merchant banking entities, 
and a majority ownership in a real-estate development partnership. Our primary earnings come from the spread between 
the interest earned on interest-bearing assets and the interest paid on interest-bearing liabilities. In addition, we generate 
income from fees on products offered to commercial, consumer and international customers.  The sales team of each of 
our Subsidiary Banks aims to match the right mix of products and services to each customer to best serve the customer’s 
needs.  That process entails spending time with customers to assess those needs and servicing the sales arising from those 
discussions  on  a  long  term  basis.    Our  Subsidiary  Banks  have  various  compensation  plans,  including  incentive  based 
compensation, for fairly compensating employees.  Our Subsidiary Banks also have a robust process in place to review 
sales that support the incentive based compensation plan to monitor the quality of the sales and identify any significant 
irregularities, a process that has been in place for many years. 

One of our primary goals is to grow net interest income and non-interest income while adequately managing 
credit risk, interest rate risk and expenses. Effective management of capital is one of our critical objectives. A key measure 

3 

of the performance of a banking institution is the return on average common equity (“ROE”). Our ROE for the year ended 
December 31, 2018 was 11.22% as compared to 8.62% for the year ended December 31, 2017. 

We are very active in facilitating trade along the United States border with Mexico. We do a large amount of 
business with customers domiciled in Mexico. Deposits from persons and entities domiciled in Mexico comprise a large 
and stable portion of the deposit base of our Subsidiary Banks. The loan policies of our Subsidiary Banks generally require 
that loans to borrowers domiciled in foreign countries be primarily secured by assets located in the United States or have 
credit enhancements in the form of guarantees, from significant United States corporations. We also serve the growing 
Hispanic population through our facilities located throughout north, south, central and southeast Texas and the State of 
Oklahoma. 

Expense control is an essential element in our long-term profitability. As a result, we monitor the efficiency ratio, 
which  is  a  measure  of  non-interest  expense  to  net  interest  income  plus  non-interest  income  closely.  As  we  adjust  to 
regulatory changes related to the Dodd-Frank Act, including congressional efforts to revamp or reform it, our efficiency 
ratio may suffer because the additional regulatory compliance costs are expected to increase non-interest expense. We 
monitor this ratio over time to assess our efficiency relative to our peers. We use this measure as one factor in determining 
if we are accomplishing our long-term goals of providing superior returns to our shareholders.

Net Income 

Net income for the year ended December 31, 2018 increased by 37.2% compared to the same period of 2017.  
Net income for the years ended December 31, 2018 and December 31, 2017 was positively affected by a decrease in the 
provision for probable loan losses from the prior year as a result of a decrease in the historical loss experience in the 
commercial category of the allowance for probable loan loss calculation.  As discussed in prior periods, charge-offs had 
increased due to  the deterioration of one  relationship  that  was  secured by  multiple  pieces  of  transportation  equipment 
beginning in the fourth quarter of 2014.  We use a three-year historical charge-off experience in the calculation, therefore, 
as those charge-offs begin to be eliminated, the allowance for probable loan losses will be impacted.  As fluctuations occur 
in historical loss factors, management evaluates the need to adjust the qualitative factors used in the calculation to properly 
reflect probable loan losses.  Net income for the year ended December 31, 2018 was also positively impacted by an increase 
in net interest income due to a higher volume of loans and an increase in the overall yield on the loan portfolio.  Interest 
expense  increased  for  the  year  ended  December 31,  2018  compared  to  the  same  period  of  2017  and  can  be  attributed 
primarily to an increase in the cost of borrowings and an increase in the interest paid on savings and time deposit accounts, 
which have increased because of Federal Reserve Board actions to raise interest rates.  Net income for 2018 was also 
positively  impacted  by  a  decrease  in  the  effective  tax  rate  arising  from  the  Tax  Cut  and  Jobs  Act  signed  into  law  on 
December 22, 2017, resulting in a decrease in income tax expense of approximately $38.6 million due to the decrease in 
the corporate tax rate from 35% to 21%.  Net income for the year ended December 31, 2017 increased by 17.5% compared 
to the same period in 2016.  Net income for the year ended December 31, 2017 was positively impacted by an increase in 
net interest income.  Net interest income increased as interest income on loans increased due to a higher volume of loans 
and an increase in the overall yield on the loan portfolio.  Interest expense declined primarily due to the effects of the early 
termination of the long-term repurchase agreements by the lead Subsidiary Bank in prior years.  Net income for the year 
ended  December 31, 2017 was  also positively  impacted  by  a  tax  refund  received  in  the  second quarter of 2017  in  the 
amount of $4.9 million as a result of an amended tax return for the 2012 tax year.  In September 2014, we amended our 
2012 federal income tax return as a result of a tax opinion obtained regarding a judgment against us paid in 2012 after 
litigation related to tax matters in our 2004 acquisition of Local Financial Corporation (“LFIN”).  Litigation was initiated 
against us by the former controlling shareholders of LFIN with respect to such tax matters.  On March 5, 2010, a judgment 
was entered against us on a jury verdict in the U.S. District Court for the Western District of Oklahoma.  We subsequently 
appealed the decision and on January 5, 2012, the United States Court of Appeals Tenth Circuit affirmed the judgment 
and it became final and unappealable and we recorded the majority of the payment of the judgment as a non-deductible 
expense in our 2012 federal income tax return.  We engaged legal counsel to review the deductibility of the judgment and, 
upon receiving a tax opinion, amended the 2012 tax return to report the payment as a deductible expense.  The Internal 
Revenue Service examined the amended return and at the conclusion of the exam, allowed a certain portion of the judgment 
to be deducted as a necessary and ordinary business expense.  Net income for the year ended December 31, 2017 was 
negatively impacted by a charge of $5.8 million, $3.7 million after tax, taken by the lead Subsidiary Bank in connection 
with the termination of its long-term repurchase agreements outstanding in order to help manage its long-term funding 
costs, recorded in the first quarter of 2017.       

Net Interest Income 

Net interest income is the spread between income on interest-earning assets, such as loans and securities, and the 
interest expense on liabilities used to fund those assets, such as deposits, repurchase agreements and funds borrowed. Net 
interest income is our largest source of revenue. Net interest income is affected by both changes in the level of interest 

5 

rates and changes in the amount and composition of interest-earning assets and interest-bearing liabilities. Tax-exempt 
yields have not been adjusted to a tax-equivalent basis.

The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net 
income and net interest margin. The yield on average interest-earning assets increased 13.1% from 3.97% in 2017 to 4.49% 
in 2018, and the rates paid on average interest-bearing liabilities increased 38.6% from 0.57% in 2017 to 0.79% in 2018. 
The yield on average interest-earning assets increased 5.9% from 3.75% in 2016 to 3.97% in 2017, and the rates paid on 
average  interest-bearing  liabilities  decreased  8.1%  from  .62%  in  2016  to  .57%  in  2017.  The  majority  of  our  taxable 
investment securities are invested in mortgage backed securities and, during rapid increases or reduction in interest rates, 
the yield on these securities do not re-price as quickly as the loans.

(1)  The change in interest due to both rate and volume has been allocated to volume and rate changes in proportion to the relationship of the absolute 

dollar amounts of the change in each. 

As part of our strategy to manage interest rate risk, we strive to manage both assets and liabilities so that interest 
sensitivities match. One method of calculating interest rate sensitivity is through gap analysis. A gap is the difference 
between the amount of interest rate sensitive assets and interest rate sensitive liabilities that re-price or mature in a given 
time period. Positive gaps occur when interest rate sensitive assets exceed interest rate sensitive liabilities, and negative 
gaps occur when interest rate sensitive liabilities exceed interest rate sensitive assets. A positive gap position in a period 
of rising interest rates should have a positive effect on net interest income as assets will re-price faster than liabilities. 
Conversely, net interest income should contract somewhat in a period of falling interest rates. Management can quickly 
change our interest rate position at any given point in time as market conditions dictate. Additionally, interest rate changes 
do  not  affect  all  categories  of  assets  and  liabilities  equally  or  at  the  same  time.  Analytical  techniques  we  employ  to 
supplement gap analysis include simulation analysis to quantify interest rate risk exposure. The gap analysis prepared by 
management is reviewed by our Investment Committee twice a year. The Investment Committee is comprised of certain 
members of the board of directors, senior managers of the various Subsidiary Banks along with consultants. Management 
currently believes that we are properly positioned for interest rate changes; however, if management determines at any 
time that we are not properly positioned, we will strive to adjust the interest rate sensitive assets and liabilities in order to 
manage the effect of interest rate changes. 

We have established guidelines for acceptable volatility of projected net interest income on the income simulation 
analysis and the guidelines are reviewed at least annually. As of December 31, 2018, in rising rate scenarios of +100, 
+200, +300 and +400 basis points, the guidelines established by management require that the net interest income not vary 
by more than plus or minus 15%, 15%, 15%, and 20%, respectively and in a decreasing rate scenario of -100 or -175 basis

points,  that  the  net  interest  income  not  vary  by  more  than  plus  or  minus  15%.  At  December 31,  2018,  the  income 
simulations show that a rate shift of -175, -100, +100, +200, +300 and +400 basis points in interest rates up will vary 
projected  net  interest  income  for  the  coming  12 month  period  by -5.55%, -3.24%,  +3.96%,  +7.70%,  +11.39%  and 
+14.93%, respectively. The basis point shift in interest rates is a hypothetical rate scenario used to calibrate risk, and does 
not necessarily represent management’s current view of future market developments. We believe that we are properly 
positioned for a potential interest rate increase or decrease.

Domestic loans accounted for on a non-accrual basis decreased at December 31, 2018 by 71% compared to the 
same period of 2017.  The decrease can be attributed to the foreclosure of a relationship primarily secured by a water park 
and the foreclosure of the collateral on a relationship secured by multiple pieces of transportation equipment.  Domestic 
loans contractually past due ninety days and still accruing increase at December 31, 2018 compared to the same period of 
2017 and can be attributed to a relationship that is secured by multiple pieces of real property on which car dealerships are 
operated.  The relationship remained on accrual since we had a court approved debtor in possession plan that provided that 
the sponsors of the plan wold assume full responsibility for the plan, including accrued and unpaid interest. 

The allowance for probable loan losses decreased 9.3% to $61,384,000 at December 31, 2018 from $67,687,000 
at December 31, 2017. The allowance was .94% of total loans, net of unearned income at December 31, 2018 and 1.07% 
at December 31, 2017. The provision for probable loan losses charged to expense decreased $5,109,000 to $6,112,000 for 
the  year  ended  December 31,  2018 from  $11,221,000  for the  same  period  in  2017.   The  decrease  in  the provision  for 
probable  loan  losses  charged  to  expense  for  the  year  ended  December 31,  2018  can  be  attributed  to  a  decrease  in  the 
historical  charge-off  experience  in  the  commercial  category  of  the  allowance  for  probable  loan  loss  calculation.    As 
discussed  in  prior  periods,  charge-offs  had  increased  due  to  the  deterioration  of  one  relationship  that  was  secured  by 
multiple pieces of transportation equipment beginning in the fourth quarter of 2014.  We use a three-year historical charge-
off experience in the calculation, therefore, as those charge-offs begin to be eliminated from the calculation, the allowance 
for probable loan losses will be impacted.  As fluctuations occur in historical loss factors, management evaluates the need 
to  adjust  the  qualitative  factors  used  in  the  calculation  to  properly  reflect  probable  loan  losses.    The  decrease  in  the 
provision for probable loan losses charged to expense for the year ended December 31, 2016 can be attributed to two  large 
recoveries on loans that had been charged-off in prior years of approximately $10.4 million.  The recoveries positively 
impacted  the  balance  in  the  allowance  for  probable  loan  losses  and  resulted  in  a  decrease  to  provision  expense.    The 
increase  in  the  provision  for  probable  loan  losses  charged  to  expense  for  the  year  ended  December 31,  2015  can  be 
attributed to an increase in the portion of the allowance for probable loan losses calculated based on actual historical loss 
experience in the commercial loan category of our loan portfolio.

The gross income that would have been recorded during 2018, 2017 and 2016 on non-accrual loans in accordance 
with  their  original  contract  terms  was  approximately  $1,119,000,  $977,000  and  $2,438,000  on  domestic  loans  and 
approximately $0, $0, and $23,800 on foreign loans, respectively. The amount of interest income on such loans that was 
recognized in 2018, 2017 and 2016 was approximately $4,000, $4,000, and $0 on domestic loans and $0, $0, and $0 for 
foreign loans, respectively. 

Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/or 
management  deems  the  collectibility  of  the  principal  and/or  interest  to  be  in  question,  as  well  as  when  required  by 
applicable  regulatory  guidelines.  Interest  income  on  non-accrual  loans  is  recognized  only  to  the  extent  payments  are 
received or when, in management’s opinion, the creditor’s financial condition warrants reestablishment of interest accruals. 
Under special circumstances, a loan may be more than 90 days delinquent as to interest or principal and not be placed on 
non-accrual status. This situation generally results when a Subsidiary Bank has a borrower who is experiencing financial 
difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed 
of loans that are considered to be adequately secured and/or for which there has been a recent history of payments. When 
a loan is placed on non-accrual status, any interest accrued, not paid, is reversed and charged to operations against interest 
income. 

Loan  commitments,  consisting  of  unused  commitments  to  lend,  letters  of  credit,  credit  card  lines  and  other 
approved loans, that have not been funded, were approximately $3,076,184,000 and $2,915,326,000 at December 31, 2018 
and 2017, respectively. See Note 19 to the Consolidated Financial Statements.

The allowance for probable loan losses primarily consists of the aggregate loan loss allowances of the Subsidiary 

Banks. The allowances are established through charges to operations in the form of provisions for probable loan losses. 

The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well 
as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial and agricultural 
or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure 
beyond  any  collateral  coverage  is  apparent,  (ii) when  no  further  collection  of  the  portion  of  the  loan  so  exposed  is 
anticipated  based  on  actual  results,  (iii) when  the  credit  enhancements,  if  any,  are  not  adequate,  and  (iv) when  the 
borrower’s financial condition would so indicate. Generally, unsecured consumer loans are charged-off when 90 days past 
due. As discussed in prior periods, charge-offs had increased due to the deterioration of one relationship that was secured 
by multiple pieces of transportation equipment beginning in the fourth quarter of 2014 and increased charge-offs for the 
twelve months ended December 31, 2016 and December 31, 2015.  In March 2016, litigation against the management of 
the borrower was filed in the State of Nevada, resulting in a going concern issue with the borrower’s operations and the 
future use of the transportation equipment pledged as collateral on the relationship.  As a result, management, in accordance 
with its credit review procedures, re-evaluated the collateral values on the equipment in light of the new circumstances 
and reduced the collateral values accordingly, resulting in a further charge-down of the relationship of approximately $19.4 
million, which is included in the losses charged to the allowance in the commercial category in the table detailing the 
activity for the twelve months ended December 31, 2016.  The same relationship had been previously charged-down in 
the years ended December 31, 2015 and 2014.  Two recoveries on loans charged-off in prior years are included in the 
recoveries credited to the allowance in the table detailing activity for the year ended December 31, 2016.  The recoveries 
occurred in the first and third quarters of 2016 in the amounts of $4.4 million and $6 million, respectively, and are included 
in the Commercial and Commercial Real Estate: Other Construction and Land Development categories.  The increase in 
charge-offs for the years ended December 31, 2015 and 2014 in the Commercial category can be attributed to a charge-
down of a relationship that is primarily secured by multiple pieces of transportation equipment.  The relationship was 
charged-down  by  $13.5  million  and  $8.5  million  for  the  years  ended  December 31,  2015  and  December 31,  2014, 
respectively. 

The  allowance  for  probable  loan  losses  is  a  reserve  established  through  a  provision  for  probable  loan  losses 
charged to expense, which represents management’s best estimate of probable loan losses within the existing portfolio of 
loans.  Our  allowance  for  probable  loan  loss  methodology  is  based  on  guidance  provided  in  Securities  and  Exchange 
Commission  Staff  Accounting  Bulletin  No. 102,  “Selected  Loan  Loss  Allowance  Methodology  and  Documentation 
Issues”  and  includes  allowance  allocations  calculated  in  accordance  with  ASC  310,  “Receivables”  and  ASC  450, 
“Contingencies.”  Please  refer  to  Note 4—Allowance  for  Probable  Loan  Losses  in  the  accompanying  Notes  to  the 
consolidated Financial Statements. 

While our management considers that it is generally able to identify borrowers with financial problems reasonably 
early and to monitor credit extended to such borrowers carefully, there is no precise method of predicting loan losses. The

determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an 
exercise of judgment. Similarly, the determination of the adequacy of the allowance for probable loan losses can be made 
only on a subjective basis. Our management believes that the allowance for probable loan losses at December 31, 2018 
was adequate to absorb probable losses from loans in the portfolio at that date. See Critical Accounting Policies on page 24. 
Should any of the factors considered by management in evaluating the adequacy of the allowance for probable loan losses 
change,  our  estimate  of  probable  loan  losses  could  also  change,  which  could  affect  the  level  of  future  provisions  for 
probable loan losses.

Total non-interest income for the year ended December 31, 2018 increased by 9.7% compared to the same period 
of 2017.  Other income for the year ended December 31, 2018 was positively impacted by our share of income from a real 
estate  development  partnership  in  which  we  hold  a  majority  interest.    Total  non-interest  income  for  the  year  ended 
December 31, 2017 decreased by 7.0% compared to the same period of 2016.  The decrease in total non-interest income 
for the year ended December 31, 2017 can be attributed to an increase in losses recognized on the sales of certain available-
for-sale investment securities in 2017 to re-position a portion of our investment portfolio and to certain infrequent items 
recorded in 2016.

Non-interest expense for the year ended December 31, 2018 increased by 2.0% compared to the same period of 
2017.  Non-interest expense for the year ended December 31, 2018 was negatively impacted by an increase in the cost of

operations on other real estate owned and due to an increase in the specific reserve on a property as part of the re-evaluation 
of  the  carrying  value  of  said  property.    Non-interest  expense  for  the  year  ended  December 31,  2017  increased  1.4% 
compared to the same period of 2016.  Non-interest expense for 2017 was positively impacted by a decrease in deposit 
insurance assessments arising from a decrease in the assessment rate set by the FDIC of $2.4 million and a decrease in the 
net cost of operations on other real estate owned as the size of the portfolio has decreased from prior periods.  Non-interest 
expense for the period was negatively impacted by increased technology costs related to certain network infrastructure 
modifications of $4.1 million for the year ended December 31, 2017 compared to the same period of 2016.   

Effects of Inflation 

The principal component of earnings is net interest income, which is affected by changes in the level of interest 
rates. Changes in rates of inflation affect interest rates. It is difficult to precisely measure the impact of inflation on net 
interest income because it is not possible to accurately differentiate between increases in net interest income resulting from 
inflation and increases resulting from increased business activity. Inflation also raises costs of operations, primarily those 
of employment and services.

Mortgage-backed  securities  are  securities  primarily  issued  by  the  Federal  Home  Loan  Mortgage  Corporation 
(“Freddie  Mac”),  Federal  National  Mortgage  Association  (“Fannie  Mae”),  and  the  Government  National  Mortgage 
Association (“Ginnie Mae”). Investments in mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the 
U.S.  government.  Investments  in  mortgage-backed  securities  issued  by  Freddie  Mac  and  Fannie  Mae  are  not  fully 
guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds 
with  limited  credit  risk, particularly  given  the  placement  of Fannie  Mae  and Freddie  Mac  into  conservatorship by  the 
federal government in 2008 and because securities issued by others that are collateralized by residential mortgage-backed 
securities issued by Fannie Mae or Freddie Mac are rated consistently as AAA rated securities.

International Operations 

On December 31, 2018, we had $150,517,000 (1.3% of total assets) in loans outstanding to borrowers domiciled 
in foreign countries, which included primarily borrowers domiciled in Mexico. The loan policies of our Subsidiary Banks 
generally require that loans to borrowers domiciled in foreign countries be primarily secured by assets located in the United 
States or have credit enhancements in the form of guarantees, from significant United States corporations. The composition 
of such loans and the related amounts of allocated allowance for probable loan losses as of December 31, 2018 and 2017 
is presented below.

We offer a variety of deposit accounts having a wide range of interest rates and terms. We rely primarily on our 
high  quality  customer  service,  sales  programs,  customer  referrals  and  advertising  to  attract  and  retain  these  deposits. 
Deposits provide the primary source of funding for our lending and investment activities, and the interest paid for deposits 
must be managed carefully to control the level of interest expense. Deposits at December 31, 2018 were $8,696,545,000, 
an increase of 1.8% from $8,544,892,000 at December 31, 2017. Although deposits at December 31, 2018 increased from

December 31,  2017  and  we  have  experienced  growth  in  deposits  over  the  last  few  years,  we  are  still  experiencing  a 
substantial amount of competition for deposits at higher than market rates.  As a result, we have attempted to maintain 
certain deposit relationships, but have allowed certain deposits to leave as the result of aggressive pricing by competitors.   

Other Borrowed Funds 

Other borrowed funds include FHLB borrowings which are short-term and long-term borrowings issued by the 
FHLB of Dallas and the FHLB of Topeka at the market price offered at the time of funding.  These borrowings are secured 
by residential mortgage-backed investment securities and a portion of our loan portfolio.  At December 31, 2018, other 
borrowed funds totaled $705,655,000, an increase of 41.0% from $1,195,225,000 at December 31, 2017.  The decrease in 
borrowings can be attributed to an increase in cash arising from principal pay downs on available-for-sale debt securities 
and deposits.

Liquidity and Capital Resources 

Liquidity 

The maintenance of adequate liquidity provides our Subsidiary Banks with the ability to meet potential depositor 
withdrawals,  provide  for  customer  credit  needs,  maintain  adequate  statutory  reserve  levels  and  take  full  advantage  of 
high-yield  investment  opportunities  as  they  arise.  Liquidity  is  afforded  by  access  to  financial  markets  and  by  holding 
appropriate amounts of liquid assets. Our Subsidiary Banks derive their liquidity largely from deposits of individuals and 
business entities. Other important funding sources for our Subsidiary Banks during 2018 and 2017 were borrowings from 
the FHLB, securities sold under repurchase agreements and large certificates of deposit, requiring management to closely 
monitor its asset/liability mix in terms of both rate sensitivity and maturity distribution. Our Subsidiary Banks have had a 
long-standing relationship with the FHLB and keep open, unused, lines of credit in order to fund liquidity needs. In the 
event that the FHLB indebtedness is not renewed, the repayment of the outstanding indebtedness would more than likely 
be repaid through proceeds generated from the sales of unpledged available-for-sale securities. We maintain a sizable, 
high quality investment portfolio to provide significant liquidity. These securities can be sold or sold under agreements to 
repurchase, to provide immediate liquidity. As in the past, we will continue to monitor the volatility and cost of funds in 
an attempt to match maturities of rate-sensitive assets and liabilities and respond accordingly to anticipated fluctuations in 
interest rates over reasonable periods of time. 

Asset/Liability Management 

Our  funds  management  policy  has  as  its  primary  focus  the  measurement  and  management  of  the  Subsidiary 
Banks’ earnings at risk in the face of rising or falling interest rate forecasts. The earliest and most simplistic concept of 
earnings at risk measurement is the gap report, which is used to generate a rough estimate of the vulnerability of net interest 
income to changes in market rates as implied by the relative re-pricings of assets and liabilities. The gap report calculates 
the difference between the amounts of assets and liabilities re-pricing across a series of intervals in time, with emphasis 
typically placed on the one-year period. This difference, or gap, is usually expressed as a percentage of total assets. 

17 

 
 
  
 
 
  
 
     
     
     
  
 
 
 
 
 
 
 
 
If an excess of liabilities over assets matures or re-prices within the one-year period, the statement of condition 
is said to be negatively gapped. This condition is sometimes interpreted to suggest that an institution is liability-sensitive, 
indicating that earnings would suffer from rising rates and benefit from falling rates. If a surplus of assets over liabilities 
occurs in the one-year time frame, the statement of condition is said to be positively gapped, suggesting a condition of 
asset sensitivity in which earnings would benefit from rising rates and suffer from falling rates. 

The gap report thus consists of an inventory of dollar amounts of assets and liabilities that have the potential to 
mature or re-price within a particular period. The flaw in drawing conclusions about interest rate risk from the gap report 
is that it takes no account of the probability that potential maturities or re-pricings of interest-rate-sensitive accounts will 
occur, or at what relative magnitudes. Because simplicity, rather than utility, is the only virtue of gap analysis, financial 
institutions increasingly have either abandoned gap analysis or accorded it a distinctly secondary role in managing their 
interest-rate risk exposure. 

The  net  interest  rate  sensitivity  at  December 31,  2018,  is  illustrated  in  the  following  table.  This  information 
reflects the balances of assets and liabilities whose rates are subject to change. As indicated in the table below, we are 
asset  sensitive  through  the majority of  the  time  periods  illustrated. The  table  shows the  sensitivity of  the  statement of 
condition at one point in time and is not necessarily indicative of the position at future dates.

without the limitations of gap analysis. In particular, the fundamental, but often unstated, assumption of the gap approach 
that every statement of condition item that can re-price will do so to the full extent of any movement in market interest 
rates is taken into consideration in income simulation analysis. 

Accordingly,  income  simulation  analysis  captures  not  only  the  potential  of  assets  and  liabilities  to  mature  or 
re-price,  but  also  the  probability  that  they  will  do  so.  Moreover,  income  simulation  analysis  focuses  on  the  relative 
sensitivities of these balance sheet items and projects their behavior over an extended period of time in a motion picture 
rather than snapshot fashion. Finally, income simulation analysis permits management to assess the probable effects on 
balance sheet items not only of changes in market interest rates, but also of proposed strategies for responding to such 
changes.  We  and  many  other  institutions  rely  primarily  upon  income  simulation  analysis  in  measuring  and  managing 
exposure to interest rate risk. 

We have established guidelines for acceptable volatility of projected net interest income on the income simulation 
analysis and the guidelines are reviewed at least annually. As of December 31, 2018, in rising rate scenarios of +100, 
+200, +300 and +400 basis points, the guidelines established by management require that the net interest income not vary 
by more than plus or minus 15%, 15%, 15%, and 20%, respectively and in a decreasing rate scenario of -100 or -175 basis 
points,  that  the  net  interest  income  not  vary  by  more  than  plus  or  minus  15%.  At  December 31,  2018,  the  income 
simulations show that a rate shift of -175, -100, +100, +200, +300 and +400 basis points in interest rates up will vary 
projected  net  interest  income  for  the  coming  12 month  period  by -5.55%, -3.24%,  +3.96%,  +7.70%,  +11.39%  and 
+14.93%, respectively. The basis point shift in interest rates is a hypothetical rate scenario used to calibrate risk, and does 
not necessarily represent management’s current view of future market developments. We believe that we are properly 
positioned for a potential interest rate increase or decrease. 

All the measurements of risk described above are made based upon our business mix and interest rate exposures 
at  the  particular  point  in  time.  The  exposure  changes  continuously  as  a  result  of  our  ongoing  business  and  our  risk 
management initiatives. While management believes these measures provide a meaningful representation of our interest 
rate sensitivity, they do not necessarily take into account all business developments that have an effect on net income, such 
as changes in credit quality or the size and composition of the statement of condition. 

Our principal sources of liquidity and funding dividends from subsidiaries and borrowed funds, with such funds 
being used to finance our cash flow requirements. We closely monitor the dividend restrictions and availability from our 
Subsidiary Banks as disclosed in Note 20 to the Consolidated Financial Statements. At December 31, 2018, the aggregate 
amount legally available to be distributed to us from our Subsidiary Banks as dividends was approximately $768,900,000, 
assuming that each Subsidiary Bank continues to be classified as “well-capitalized” under the applicable regulations in 
effect  at  December 31,  2018.  The  restricted  capital  (capital  and  surplus)  of  our  Subsidiary  Banks  was  approximately 
$784,416,000  as  of  December 31,  2018.  The  undivided  profits  of  our  Subsidiary  Banks  were  approximately 
$1,223,017,000 as of December 31, 2018.  

At December 31, 2018, we had outstanding $705,655,000 in other borrowed funds and $160,416,000 in junior 
subordinated  deferrable  interest  debentures.  In  addition  to  borrowed  funds  and  dividends,  we  have  a  number  of  other 
available alternatives to finance the growth of our Subsidiary Banks as well as future growth and expansion. 

Capital 

We  maintain  an  adequate  level  of  capital  as  a  margin  of  safety  for  our  depositors  and  shareholders.  At 
December 31,  2018,  shareholders’  equity  was  $1,939,582,000  compared  to  $1,838,980,000  at  December 31,  2017,  an 
increase of $100,602,000, or 5.5%. Shareholders’ equity increased primarily due to the retention of earnings, offset by the 
payment  of  cash  dividends  to  shareholders  and  repurchases  of  our  common  stock  in  the  form  of  treasury  stock.  The 
accumulated other comprehensive loss is not included in the calculation of regulatory capital ratios. 

During 1990, the Federal Reserve Board (“FRB”) adopted a minimum leverage ratio of 3% for the most highly 
rated bank holding companies and at least 4% to 5% for all other bank holding companies. Our leverage ratio (defined as 
shareholders’  equity  plus  eligible  trust  preferred  securities  issued  and  outstanding  less  goodwill  and  certain  other 
intangibles divided by average quarterly assets) was 15.87% at December 31, 2018 and 14.62% at December 31, 2017. 

19 

The core deposit intangibles and goodwill of $282,532,000 as of December 31, 2018, are deducted from the sum of core 
capital elements when determining our capital ratios. 

The FRB has adopted risk-based capital guidelines which assign risk weightings to assets and off-balance sheet 
items. The guidelines also define and set minimum capital requirements (risk-based capital ratios). Under the final 1992 
rules, all banks are required to have Tier 1 capital of at least 4.0% of risk-weighted assets and total capital of 8.0% of 
risk-weighted assets. Tier 1 capital consists principally of shareholders’ equity plus trust preferred securities issued and 
outstanding  less  goodwill  and  certain  other  intangibles,  while  total  capital  consists  of  Tier 1  capital,  certain  debt 
instruments and a portion of the reserve for loan losses. In order to be deemed well-capitalized pursuant to the regulations, 
an institution must have a total risk-weighted capital ratio of 10%, a Tier 1 risk-weighted ratio of 8% and a Tier 1 leverage 
ratio of 5%. We had risk-weighted Tier 1 capital ratios of 19.06% and 18.73% and risk weighted total capital ratios of 
19.74%  and  19.51%  as  of  December 31,  2018  and  2017,  respectively,  which  are  well  above  the  minimum  regulatory 
requirements and exceed the well-capitalized ratios (see Note 20 to Notes to Consolidated Financial Statements). 

In July 2013, the Federal Deposit Insurance Corporation (“FDIC”) and other regulatory bodies established a new, 
comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both 
the quantity and quality of capital held by banking organizations. The final rules are a result of the implementation of the 
BASEL III capital reforms and various Dodd-Frank Act related capital provisions. Consistent with the Basel international 
framework, the rules include a new minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% 
and a CET1 capital conservation buffer of 2.5% of risk-weighted assets.  The capital conservation buffer began phasing-in 
on January 1, 2016 at .625% and increased each year until January 1, 2019, when we were required to have a 2.5% capital 
conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon 
full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and 
include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the new rules 
emphasize CET1 capital and implements strict eligibility criteria for regulatory capital instruments. The new rules also 
improve the methodology for calculating risk-weighted assets to enhance risk sensitivity. The new rules are subject to a 
four year phase in period for mandatory compliance and we were required to begin to phase in the new rules beginning on 
January 1, 2015.  Management believes, as of December 31, 2018, that we and each of our Subsidiary Banks will meet all 
capital adequacy requirements once the capital conservation is fully phased-in. 

On November 21, 2017, the Office of the Comptroller of the Currency (“OCC”), the FRB and the FDIC finalized 
a proposed rule that extends the current treatment under the regulatory capital rules for certain regulatory capital deductions 
and risk weights and certain minority interest requirements, as they apply to banking organizations that are not subject to 
the advanced approaches capital rules.  Effective January 1, 2018, the rule also pauses the full transition to the Basel III 
treatment of mortgage servicing assets, certain deferred tax assets, investments in the capital of unconsolidated financial 
institutions and minority interests.  The agencies are also considering whether to make adjustments to the capital rules in 
response  to  CECL  (the  FASB  Standard relating  to  current expected  credit  loss)  and  its  potential  impact  on regulatory 
capital. 

On December 7, 2017, the Basel Committee on Banking Supervision unveiled the latest round of its regulatory 
capital framework, commonly called “Basel IV.”  The framework makes changes to the capital framework first introduced 
as “Basel III” in 2010.  The committee targeted 2022-2027 as the timeframe for implementation by regulators in individual 
countries, including the U.S. federal bank regulatory agencies (after notice and comment). 

In December 2018, the federal banking regulators issued a final rule that would provide an optional three-year 
phase-in  period  for  the  day-one  regulatory  capital  effects  of  the  adoption  of  Accounting  Standards  Update 
(“ASU”) 2016-13 to ASC 326, “Financial Instruments – Credit Losses,” as amended, on January 1, 2020. 

Junior Subordinated Deferrable Interest Debentures 

We have formed six statutory business trusts under the laws of the State of Delaware, for the purpose of issuing 
trust preferred securities. These statutory business trusts (the “Trusts”) have each issued Capital and Common Securities 
and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) that we 

20 

issued.  As  of  December 31,  2018  and  December 31,  2017,  the  principal  amount  of  debentures  outstanding  totaled 
$160,416,000.  

The Debentures are subordinated and junior in right of payment to all of our present and future senior indebtedness 
(as defined in the respective indentures), and are pari passu with one another. The interest rate payable on, and the payment 
terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and 
Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the 
Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the 
Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive 
quarterly  periods  on  Trusts  VI,  VIII,  IX,  X,  XI  and  XII.  If  interest  payments  on  any  of  the  Debentures  are  deferred, 
distributions on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption 
prior to maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory 
bodies. 

For financial reporting purposes, the Trusts are treated as investments and not consolidated in the consolidated 
financial  statements.  Although  the  Capital  Securities  issued  by  each of  the Trusts  are  not  included  as  a  component  of 
shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory 
purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 
capital up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that exceeds the 25% threshold 
would  qualify  as  Tier 2  capital.  At  December 31,  2018  and  December 31,  2017,  the  total  $160,416,000  of  the  Capital 
Securities outstanding qualified as Tier 1 capital.

Critical Accounting Policies 

We have established various accounting policies which govern the application of accounting principles in the 
preparation of our consolidated financial statements. The significant accounting policies are described in the Notes to the 
Consolidated Financial Statements. Certain accounting policies involve significant subjective judgments and assumptions 
by management which have a material impact on the carrying value of certain assets and liabilities; management considers 
such accounting policies to be critical accounting policies. 

We consider our allowance for probable loan losses as a policy critical to the sound operations of our  Subsidiary 
Banks. The allowance for probable loan losses primarily consists of the aggregate loan loss allowances of our Subsidiary 
Banks. The allowances are established through charges to operations in the form of provisions for probable loan losses. 
Loan losses or recoveries are charged or credited directly to the allowances. The allowance for probable loan losses of 
each Subsidiary Bank is maintained at a level considered appropriate by management, based on estimated probable losses 
in the loan portfolio. The allowance is derived from the following elements: (i) allowances established on specific impaired 
loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay 
the loan, the underlying collateral values, and the industry in which the customer operates, (ii) allowances based on actual 
historical loss experience for similar types of loans in our loan portfolio, and (iii) allowances based on general economic 
conditions, changes in the mix of loans, company resources, border risk and credit quality indicators, among other things. 
See also discussion regarding the allowance for probable loan losses and provision for probable loan losses included in 
the results of operations and “Provision and Allowance for Probable Loan Losses” included in Notes 1 and 4 of the Notes 
to Consolidated Financial Statements. 

The loan loss provision is determined using the following methods. On a weekly basis, loan past due reports are 
reviewed by the credit quality committee to determine if a loan has any potential problems and if a loan should be placed 
on our internal classified report. Additionally, our credit department reviews the majority of our loans for proper internal 
classification purposes regardless of whether they are past due and segregates any loans with potential problems for further 
review. The credit department will discuss the potential problem loans with the servicing loan officers to determine any 
relevant issues that were not discovered in the evaluation. Also, an analysis of loans that is provided through examinations 
by regulatory authorities is considered in the review process. After the above analysis is completed, we will determine if 
a  loan  should  be  placed  on  an  internal  classified  report  because  of  issues  related  to  the  analysis  of  the  credit,  credit 
documents, collateral and/or payment history. 

Our internal classified report is segregated into the following categories: (i) “Special Review Credits,” (ii) “Watch 
List—Pass  Credits,”  or  (iii) “Watch  List—Substandard  Credits.”  The  loans  placed  in  the  “Special  Review  Credits” 
category reflect our opinion that the loans reflect potential weakness which require monitoring on a more frequent basis. 
The “Special Review Credits” are reviewed and discussed on a regular basis with the credit department and the lending 
staff to determine if a change in category is warranted. The loans placed in the “Watch List—Pass Credits” category reflect 
our opinion that the credit contains weaknesses which represent a greater degree of risk, which warrant “extra attention.”

The “Watch List—Pass Credits” are reviewed and discussed on a regular basis with the credit department and the lending 
staff  to  determine  if  a  change  in  category  is  warranted.  The  loans  placed  in  the  “Watch  List—Substandard  Credits” 
classification are considered to be potentially inadequately protected by the current sound worth and debt service capacity 
of the borrower or of any pledged collateral. These credit obligations, even if apparently protected by collateral value, 
have shown defined weaknesses related to adverse financial, managerial, economic, market or political conditions which 
may jeopardize repayment of principal and interest. Furthermore, there is the possibility that we may sustain some future 
loss if such weaknesses are not corrected. For loans that are classified as impaired, management evaluates these credits 
ASC 310-10, “Receivables,” and, if deemed necessary, a specific reserve is allocated to the credit. The specific reserve 
allocated  under  ASC  310-10,  is  based  on  (i) the  present  value  of  expected  future  cash  flows  discounted  at  the  loan’s 
effective interest rate; (ii) the loan’s observable market price; or (iii) the fair value of the collateral if the loan is collateral 
dependent. Substantially all of our loans evaluated as impaired under ASC 310-10 are measured using the fair value of 
collateral method. In limited cases, we may use other methods to determine the specific reserve of a loan under ASC 310-10 
if such loan is not collateral dependent. 

The allowance based on historical loss experience on our remaining loan portfolio, which includes the “Special 
Review Credits,” “Watch List—Pass Credits,” and “Watch List—Substandard Credits” is determined by segregating the 
remaining  loan  portfolio  into  certain  categories  such  as  commercial  loans,  installment  loans,  international  loans,  loan 
concentrations and overdrafts. A historical loss percentage, adjusted for (i) management’s evaluation of changes in lending 
policies  and  procedures,  (ii) current  economic  conditions  in  the  market  area  we  serve,  (iii) other  risk  factors,  (iv) the 
effectiveness  of  the  internal  loan  review  function,  (v) changes  in  loan  portfolios,  and  (vi) the  composition  and 
concentration of credit volume is applied to each category. Each category is then added together to determine the allowance 
allocated under ASC 450-20. 

Our management continually reviews the allowance for loan losses of our Subsidiary Banks using the amounts 
determined from the allowances established on specific loans, the allowance established on quantitative historical loss 
percentages, and the allowance based on qualitative data, to establish an appropriate amount to maintain our allowance for 
probable loan loss. Should any of the factors considered by management in evaluating the adequacy of the allowance for 
probable loan losses change, our estimate of probable loan losses could also change, which could affect the level of future 
provisions for probable loan losses. 

Recent Accounting Standards Issued 

See  Note 1—Summary  of  Significant  Accounting  Policies  in  the  accompanying  Notes  to  the  Consolidated 
Financial  Statements  for  details  of  recently  issued  and  recently  adopted  accounting  standards  and  their  impact  on  our 
consolidated financial statements. 

Preferred Stock, Common Stock and Dividends 

We  have  issued  and  outstanding  65,617,505  shares  of  $1.00  par  value  common  stock  held  by  approximately 
1,928 holders of record at February 25, 2019. The book value of the common stock at December 31, 2018 was $31.33 per 
share compared with $29.28 per share at December 31, 2017. In connection with our participation in the Troubled Asset 
Relief  Program  Capital  Purchase  Program  in  2008,  the  US  Treasury  received  a  warrant  (the  “Warrant”)  to  purchase 
1,326,238 shares of our common stock (the “Warrant Shares”) at $24.43 per share. The term of the Warrant is ten years 
and was immediately exercisable. The Warrant was included as a component of Tier 1 capital. On June 12, 2013, the U. S. 
Treasury sold the Warrant to a third party. On September 19, 2018, we entered into an agreement to repurchase the Warrant 
from the third party at an aggregate purchase price of $29,005,000, which transaction was consummated in the third quarter 
of  2018.  The  repurchase  of  the  outstanding  Warrant  eliminates  any  restrictions  on  certain  shareholder  distributions  or 
payment of cash dividends in excess of $0.33 per semi-annual period that would have impacted the exercise price of the 
Warrant while it remained outstanding.   

Our common stock is traded on the NASDAQ National Market under the symbol “IBOC.” The following table 
sets forth the approximate high and low bid prices in our common stock during 2018 and 2017, as quoted on the NASDAQ 
National Market for each of the quarters in the two year period ended December 31, 2018. Some of the quotations reflect 

23 

inter-dealer  prices,  without  retail  mark-up,  mark-down  or  commission  and  may  not  necessarily  represent  actual 
transactions. The closing sales price of our common stock was $40.45 per share at February 25, 2019.

On April 16 and October 16, 2018, we paid cash dividends of $0.33 and $0.42 per share to recordholders of our 
common stock on April 2 and October 9, 2018, respectively.  We paid cash dividends to the common shareholders of 
$.33 per share on April 17 and October 16, 2017 to all holders of record on April 3 and September 29, 2017, respectively.   

  Our principal source of funds to pay cash dividends on our common stock is cash dividends from our Subsidiary 

Banks. For a discussion of the limitations, please see Note 20 of Notes to Consolidated Financial Statements. 

Stock Repurchase Program 

In April 2009, following receipt of the Treasury Department’s consent, the Board of Directors re-established a 
formal stock repurchase program that authorized the repurchase of up to $40 million of common stock within the following 
twelve months and on March 5, 2018, the Board of Directors extended the repurchase program and again authorized the 
repurchase of up to $40 million of common stock during the twelve month period commencing on April 9, 2018, which 
repurchase cap the Board is inclined to increase over time. Stock repurchases may be made from time to time, on the open 
market or through private transactions. Shares repurchased in this program will be held in treasury for reissue for various 
corporate purposes, including employee stock option plans. During the fourth quarter of 2018, our Board of Directors 
adopted a Rule 10b5-1 plan and intends to adopt additional Rule 10b5-1 trading plans that will allow us to purchase shares 
of our common stock during certain trading blackout periods when we ordinarily would not be in the market due to trading 
restrictions in our internal trading policy. During the term of a 10b5-1 Plan, purchases of common stock are automatic to 
the extent the conditions of the 10b5-1 Plan’s trading instructions are met. Shares repurchased in this program will be held 
in treasury for reissue for various corporate purposes, including employee stock option plans. As of February 25, 2019, a 
total of 9,800,256 shares had been repurchased under all programs at a cost of $290,332,000. We are not obligated to 
repurchase shares under its stock repurchase program or to enter into additional Rule 10b5-1 plans. The timing, actual 
number and value of shares purchased will depend on many factors, including our cash flow and the liquidity and price 
performance of our shares of common stock. 

Except for repurchases in connection with the administration of an employee benefit plan in the ordinary course 
of business and consistent with past practices, common stock repurchases are only conducted under publicly announced

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of
International Bancshares Corporation

Opinion on the Financial Statements
We have audited the accompanying consolidated statements of condition of International Bancshares 
Corporation and its subsidiaries (the Company) as of December 31, 2018 and 2017, the related consolidated 
statements of income, comprehensive income, shareholders' equity and cash flows for each of the three years 
in the period ended December 31, 2018, and the related notes to the consolidated financial statements 
(collectively, 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, 2018 and 2017, and the results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2018, 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, 2018, 
based on criteria established in Internal Control — Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 27, 2019
expressed an unqualified opinion on the effectiveness of 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 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 audits 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.

We have served as the Company's auditor since 2007.

Notes to Consolidated Financial Statements 

(1) Summary of Significant Accounting Policies 

Our accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”) and 

to general practices within the banking industry. The following is a description of the more significant of those policies. 

Consolidation and Basis of Presentation 

Our  consolidated  financial  statements  include  the  accounts  of  the  International  Bancshares  Corporation,  its 
wholly-owned Subsidiary Banks and its wholly-owned non-bank subsidiaries, IBC Subsidiary Corporation, IBC Trading 
Company,  Premier  Tierra Holdings, Inc., IBC  Charitable and  Community  Development  Corporation,  and  IBC  Capital 
Corporation.  All significant inter-company balances and transactions have been eliminated in consolidation. 

We, through our Subsidiary Banks, are primarily engaged in the business of banking, including the acceptance of 
checking and savings deposits and the making of commercial, real estate, personal, home improvement, automobile and 
other  installment  and  term  loans.  Our  primary  markets  are  north,  south,  central,  and  southeast  Texas  and  the  state  of 
Oklahoma. Each of our Subsidiary Banks is very active in facilitating international trade along the United States border 
with Mexico and elsewhere. Although our loan portfolio is diversified, the ability of our debtors to honor their contracts 
is primarily dependent upon the economic conditions in our trade area. In addition, the investment portfolio is directly 
impacted by fluctuations in market interest rates. We are subject to the regulations of certain federal agencies as well as 
the Texas Department of Banking and the Oklahoma Department of Banking and undergo periodic examinations by those 
regulatory authorities. Such agencies may require certain standards or impose certain limitations based on their judgments 
or changes in law and regulations. 

We  own  one  insurance-related  subsidiary,  IBC  Insurance  Agency, Inc.,  a  wholly  owned  subsidiary  of  our 
Subsidiary  Bank,  International  Bank  of  Commerce,  Laredo.  The  insurance-related  subsidiary  does  not  conduct 
underwriting activities.  

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  accounting  principles  generally 
accepted in the United States of America requires management to make estimates and assumptions that affect the reported 
amounts of assets and liabilities as of the dates of the statement of condition and income and expenses for the periods. 
Actual  results  could  differ  significantly  from  those  estimates.  Material  estimates  that  are  particularly  susceptible  to 
significant changes in the near-term relate to the determination of the allowance for probable loan losses. 

Subsequent Events 

We have evaluated all events or transactions that occurred through the date we issued these financial statements. 

During this period, we did not have any material recognizable or non-recognizable subsequent events. 

Investment Securities 

We  classify  debt  securities  into  one  of  these  categories:  held-to-maturity,  available-for-sale,  or  trading.  Such 
classifications are reassessed for appropriate classification at each reporting date. Securities that are intended and expected 
to  be  held  until  maturity  are  classified  as  “held-to-maturity”  and  are  carried  at  amortized  cost  for  financial  statement 
reporting. Securities that are not positively expected to be held until maturity, but are intended to be held for an indefinite 
period of time are classified as “available-for-sale” or “trading” and are carried at their fair value. Unrealized holding gains 
and losses are included in net income for those securities classified as “trading”, while unrealized holding gains and losses 
related to those securities classified as “available-for-sale” are excluded from net income and reported net of tax as other 
comprehensive income and in shareholders’ equity as accumulated other comprehensive income (loss) until realized. We 
did not maintain any trading securities during the three-year period ended December 31, 2018. 

36 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

Mortgage-backed  securities  held  at  December 31,  2018  and  2017  represent  participating  interests  in  pools  of 
long-term first mortgage loans originated and serviced by  the issuers of the securities. Mortgage-backed securities are 
either issued or guaranteed by the U.S. government or its agencies including the Federal Home Loan Mortgage Corporation 
(“Freddie  Mac”),  the  Federal  National  Mortgage  Association  (“Fannie  Mae”),  the  Government  National  Mortgage 
Association  (“Ginnie  Mae”)  or  other  non-government  entities.  Investments  in  residential  mortgage-backed  securities 
issued by Ginnie Mae are fully guaranteed by the U. S. government. Investments in residential mortgage-backed securities 
issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. government; however, we believe that the 
quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie 
Mae and Freddie Mac into conservatorship by the federal government in 2008 and because securities issued by others that 
are collateralized by residential mortgage-backed securities issued by Fannie Mae or Freddie Mac are rated consistently 
as AAA rated securities. Market interest rate fluctuations can affect the prepayment speed of principal and the yield on the 
security. 

Premiums and discounts are amortized using the level yield or “interest method” over the terms of the securities. 
Declines in the fair value of held-to-maturity and available-for sale-securities below their cost that are deemed to be other 
than  temporary  are  reflected  in  earnings  as  realized  losses.  In  determining  whether  other-than-temporary  impairment 
exists, management considers many factors, including (i) the length of time and the extent to which the fair value has been 
less  than  cost,  (ii) the  financial  condition  and  near-term  prospects  of  the  issuer,  and  (iii) our  intent  to  hold  and  our 
determination of whether we will more likely than not be required to sell the security prior to a recovery in fair value. If 
we determine that (i) we intend to sell the security or (ii) it is more likely than not that we will be required to sell the 
security before it’s anticipated recovery, the other-than-temporary impairment that is recognized in earnings is equal to 
the difference between the fair value of the security and our amortized cost of the security. If we determine that we (i) do 
not intend to sell the security and (ii) we will not be more likely than not required to sell the security before it’s anticipated 
recovery, the other-than-temporary impairment is segregated into its two components (i) the amount of impairment related 
to credit loss and (ii) the amount of impairment related to other factors. The difference between the present value of the 
cash flows expected to be collected and the amortized cost is the credit loss recognized through earnings and an adjustment 
to the cost basis of the security. The amount of impairment related to other factors is included in other comprehensive 
income (loss). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific 
identification method.  

Equity Securities 

Prior to January 1, 2018, equity securities with readily determinable fair values were included in available-for-sale 
securities, with the unrealized gain or loss recorded as a component of other comprehensive income (loss).  Pursuant to 
the adoption of ASU 2016-02, equity securities with readily determinable fair values are a separate component of our 
balance sheet, with unrealized gains and losses recognized in net income.  Equity securities with readily determinable fair 
values at December 31, 2018 and December 31, 2017 consist primarily of Community Reinvestment Act funds. 

Provision and Allowance for Probable Loan Losses 

The allowance for probable loan losses is maintained at a level considered adequate by management to provide 
for  probable  loan  losses.  The  allowance  is  increased  by  provisions  charged  to  operating  expense  and  reduced  by  net 
charge-offs. The provision for probable loan losses is the amount, which, in the judgment of management, is necessary to 
establish the allowance for probable loan losses at a level that is adequate to absorb known and inherent risks in the loan 
portfolio. 

Management believes that the allowance for probable loan losses is adequate. While management uses available 
information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic 
conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review 
our Subsidiary Banks’ allowances for probable loan losses. Such agencies may require our Subsidiary Banks to make 

37 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

additions or reductions to their GAAP allowances based on their judgments of information available to them at the time 
of their examination. 

The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well 
as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial and agricultural 
or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure 
beyond  any  collateral  coverage  is  apparent,  (ii) when  no  further  collection  of  the  portion  of  the  loan  so  exposed  is 
anticipated  based  on  actual  results,  (iii) when  the  credit  enhancements,  if  any,  are  not  adequate,  and  (iv) when  the 
borrower’s financial condition would indicate so. Generally, unsecured consumer loans are charged-off when 90 days past 
due. 

Loans 

Loans are reported at the principal balance outstanding, net of unearned discounts. Interest income on loans is 
reported on an accrual basis. Loan fees and costs associated with originating the loans are accreted or amortized over the 
life of the loan using the interest method. We originate mortgage loans that may subsequently be sold to an unaffiliated 
third party. The loans are not securitized and if sold, are sold without recourse. Loans held for sale are carried at cost and 
the principal amount outstanding is not significant to the consolidated financial statements. 

Impaired Loans 

Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan 
agreement will not be collected. Impaired loans are measured based on (1) the present value of expected future cash flows 
discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral 
if the loan is collateral dependent. Substantially all our impaired loans are measured at the fair value of the collateral. In 
limited  cases,  we  may  use  other  methods  to  determine  the  level  of  impairment  of  a  loan  if  such  loan  is  not  collateral 
dependent. 

Troubled Debt Restructured Loans 

Troubled debt restructured loans (“TDR”) are those loans where, for reasons related to a borrower’s difficulty to 
repay a loan, we grant a concession to the borrower that we would not normally consider in the normal course of business. 
The original terms of the loan are modified or restructured. The terms that may be modified include a reduction in the 
original stated interest rate, an extension of the original maturity of the loan, a renewal of the loan at an interest rate below 
current market rates, a reduction in the principal amount of debt outstanding, a reduction in accrued interest or deferral of 
interest payments. A loan classified as a TDR is classified as an impaired loan and included in the impaired loan totals. A 
TDR  loan  may  be  returned  to  accrual  status  when  the  loan  is  brought  current,  has  performed  in  accordance  with  the 
restructured  terms  for  a  reasonable  period  of  time,  is  at  the  current  market  rate,  and  the  ultimate  collectability  of  the 
outstanding principal and interest is no longer questionable, however, although those loans may be placed back on accrual 
status, they will continue to be classified as impaired. Consistent with regulatory guidance, a TDR loan that is subsequently 
modified, but has shown sustained performance and classification as a TDR, will be removed from TDR status provided 
that the modified terms were market-based at the time of modification. 

Non-Accrual Loans 

The  non-accrual  loan  policy  of  our  Subsidiary  Banks  is  to  discontinue  the  accrual  of  interest  on  loans  when 
management determines that it is probable that future interest accruals will be un-collectible. As it relates to consumer 
loans, management charges-off those loans when the loan is contractually 90 days past due. Under special circumstances, 
a consumer or non-consumer loan may be more than 90 days delinquent as to interest or principal and not be placed on 
non-accrual status. This situation generally results when a Subsidiary Bank has a borrower who is experiencing financial 

38 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed 
of loans that are considered to be adequately secured and/or for which there are expected future payments. When a loan is 
placed on non-accrual status, any interest accrued, not paid is reversed and charged to operations against interest income. 
As  it  relates  to  non-consumer  loans  that  are  not  90 days  past  due,  management  will  evaluate  each  of  these  loans  to 
determine if placing the loan on non-accrual status is warranted. Interest income on non-accrual loans is recognized only 
to  the  extent  payments  are  received  or  when,  in  management’s  opinion,  the  debtor’s  financial  condition  warrants 
reestablishment of interest accruals. 

Other Real Estate Owned and Reposessed Assets 

Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other 
real estate is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such 
property (as determined by independent appraisal). Prior to foreclosure, the value of the underlying loan is written down 
to the fair value of the real estate to be acquired by a charge to the allowance for probable loan losses, if necessary. Any 
subsequent write-downs are charged against other non-interest expense through a valuation allowance. Other real estate 
owned totaled approximately $57,344,000 and $30,519,000 at December 31, 2018 and 2017, respectively. Other real estate 
owned is included in other assets.  Reposessed assets consist primarily of non-real estate assets acquired by foreclosure.  
Prior to foreclosure, the value of the underlying loan is written down to the fair value of the asset to be repossessed by a 
charge  to  the  allowance  for  probable  loan  losses,  if  necessary.    Reposessed  assets  are  included  in  other  assets  on  the 
consolidated financial statements and totaled approximately $6,454,000 and $303,000 at December 31, 2018 and 2017, 
respectively. 

Bank Premises and Equipment 

Bank  premises  and  equipment  are  stated  at  cost  less  accumulated  depreciation.  Depreciation  is  computed  on 
straight-line and accelerated methods over the estimated useful lives of the assets. Repairs and maintenance are charged 
to operations as incurred and expenditures for renewals and betterments are capitalized. 

Other Investments 

Other investments include equity investments in non-financial companies, as well as equity securities with no 
readily determinable fair market value. Equity investments are accounted for using the equity method of accounting. Equity 
securities with no readily determinable fair value are accounted for using the cost method. 

Cash Surrender Value of Bank Owned Life Insurance 

Cash surrender value of bank owned life insurance includes investments in cash value insurance policies to assist 
with financing employee compensation and benefit programs.  The cash value of the underlying policies accumulates on 
a tax-free basis and is received through death proceeds, which are also tax-free.  The earnings on the policies are derived 
from the investment portfolio returns of the individual insurance carriers for general account policies and on the returns 
on investments segregated in our name for separate account policies.     

Revenue Recognition 

On January 1, 2018, we adopted the provisions of ASU 2014-09 to ASC 606, “Revenue from Contracts with 
Customers.”  Since our revenue is primarily comprised of net interest income on financial assets and liabilities, which 
were excluded from the scope of the update, the remaining non-interest revenue streams were identified and then analyzed 
under the provisions of the update, to:  (i) indentify the contract, (ii) identify the performance obligation, (iii) determine 
the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when 
the performance obligation was satisfied.  Our non-interest revenue contracts with customers are primarily short term and 

39 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

our performance obligation is satisfied at a single point in time, typically within a single period.  No changes to our existing 
methods for recognizing revenue were made as a result of the update. 

Income Taxes 

Deferred income tax assets and liabilities are determined using the asset and liability method. Under this method, 
the net deferred tax asset or liability is determined based on the tax effects of the differences between the book and tax 
basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. We 
file a consolidated federal income tax return with our subsidiaries. 

Recognition  of  deferred  tax  assets  is  based  on  management’s  assessment  that  the  benefit  related  to  certain 
temporary differences, tax operating loss carry forwards, and tax credits are more likely than not to be realized. A valuation 
allowance is recorded for the amount of the deferred tax items for which it is more likely than not that the tax benefits will 
not be realized. 

We evaluate uncertain tax positions at the end of each reporting period. We may recognize the tax benefit from 
an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the 
taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from 
any such a position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized 
upon ultimate settlement. As of December 31, 2018 and 2017, respectively, after evaluating all uncertain tax positions, we 
have recorded no liability for unrecognized tax benefits at the end of the reporting period. We would recognize any interest 
accrued on unrecognized tax benefits as other interest expense and penalties as other non-interest expense. During the 
years ended December 31, 2018, 2017 and 2016, we recognized no interest expense or penalties related to uncertain tax 
positions. 

We file consolidated tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We are no longer 

subject to U.S. federal or state income tax examinations by tax authorities for years before 2015. 

Stock Options 

Compensation expense for stock awards is based on the market price of the stock on the measurement date, which 
is generally the date of grant, and is recognized ratably over the service period of the award. The fair value of stock options 
granted  was  estimated  using  the  Black-Sholes-Merton  option-pricing  model.  This  model  was  developed  for  use  in 
estimating the fair value of publicly traded options that have no vesting restrictions and are fully transferable. Additionally, 
the model requires the input of highly subjective assumptions. Because our employee stock options have characteristics 
significantly different from those of publicly traded options, and because changes in the subjective input assumptions can 
materially affect the fair value estimate, in management’s opinion, the Black-Scholes-Merton option-pricing model does 
not necessarily provide a reliable single measure of the fair value of our stock options. 

Net Income Per Share 

Basic  Earnings  Per  Share  (“EPS”)  is  calculated  by  dividing  net  income  by  the  weighted  average  number  of 
common  shares  outstanding.  The  computation  of  diluted  EPS  assumes  the  issuance  of  common  shares  for  all  dilutive 
potential common shares outstanding during the reporting period. The dilutive effect of stock options is considered in 
earnings per share calculations, if dilutive, using the treasury stock method. 

40

Notes to Consolidated Financial Statements (Continued) 

Goodwill and Identified Intangible Assets 

Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill is tested for 
impairment at least annually or on an interim basis if an event triggering impairment may have occurred. As of October 1, 
2018, after completing goodwill testing, we have determined that no goodwill impairment exists. 

Identified intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill 
because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or 
in combination with a related contract, asset, or liability. Our identified intangible assets relate to core deposits and contract 
rights.  As  of  December 31,  2018,  we  have  determined  that  no  impairment  of  identified  intangibles  exists.  Identified 
intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. See Note 6—
Goodwill and Other Intangible Assets. 

Impairment of Long-Lived Assets 

Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are 
reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not 
be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the asset 
to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset 
exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying value of 
the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of 
condition and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated. The 
assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset 
and liability sections of the statement of condition. 

Consolidated Statements of Cash Flows 

For purposes of the consolidated statements of cash flows, we consider all short-term investments with a maturity 
at date of purchase of three months or less to be cash equivalents. Also, we report transactions related to deposits and loans 
to customers on a net basis. 

Accounting for Transfers and Servicing of Financial Assets 

We  account  for  transfers  and  servicing  of  financial  assets  and  extinguishments  of  liabilities  based  on  the 
application of a financial-components approach that focuses on control. After a transfer of financial assets, we recognize 
the financial and servicing assets we control and liabilities we have incurred, derecognize financial assets when control 
has  been  surrendered  and  derecognize  liabilities  when  extinguished.  We  have  retained  mortgage  servicing  rights  in 
connection with the sale of mortgage loans. Because we may not initially identify loans as originated for resale, all loans 
are  initially  treated  as  held  for  investment.  The  value  of  the  mortgage  servicing  rights  are  reviewed  periodically  for 
impairment and are amortized in proportion to, and over the period of estimated net servicing income or net servicing 
losses. The value of the mortgage servicing rights is not significant to the consolidated statements of condition. 

Segments of an Enterprise and Related Information 

We  operate  as  one  segment.  The  operating  information  used  by  our  chief  executive  officer  for  purposes  of 
assessing performance and making operating decisions is the consolidated financial statements presented in this report. 
We have five active operating subsidiaries, namely, the Subsidiary Banks. We apply the provisions of ASC Topic 280, 
“Segment Reporting,” in determining our reportable segments and related disclosures. 

41 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

Comprehensive Income (Loss) 

Comprehensive  income  (loss)  consists  of  net  income  and  other  comprehensive  income  (loss).  Other 

comprehensive income (loss) includes unrealized gains and losses on securities available for sale. 

Advertising 

Advertising costs are expensed as incurred. 

Reclassifications 

Certain amounts in the prior year’s presentations have been reclassified to conform to the current presentation. 

These reclassifications had no effect on previously reported net income or shareholders’ equity. 

New Accounting Standards 

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 to ASC 606, “Revenue from Contracts 
with Customers.”  The update sets a common standard that defines revenue and the principles for recognizing revenue.  
The update outlines when an entity should recognize revenue, among other matters.  At its core, the update states 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 to in exchange for those goods or services.  The update also 
outlines the steps that entities should take to determine and record the current revenue number including:  (i) identify the 
contract(s) with a customer, (ii) identify the performance obligations in the contract(s), (iii) determine the transaction price, 
(iv) allocate the transaction price to the performance obligations in the contract(s), and (v) recognize revenue when (or 
as) the entity satisfies the identified performance obligations in the contract(s).  The update was originally effective for 
annual periods beginning after December 31, 2016 and the interim periods within that reporting period.  In August 2015, 
the FASB issued Accounting Standards Update No. 2015-14 which deferred the effective date of ASU 2014-09 by one 
year to annual and interim periods beginning after December 15, 2017.  On January 1, 2018, we adopted the provisions of 
ASU 2014-09 to ASC 606.  Our revenue is primarily comprised of net interest income on financial assets and financial 
liabilities,  which  is  explicitly  excluded  from  the  scope  of  ASC  606.  We  have  evaluated  the  impact  of  the  accounting 
standards update on certain other non-interest revenue streams that the provisions of the update apply to and has determined 
that  the  adoption  of  the  new  provisions  to  ASC  606  did  not  have  a  significant  impact  to  our  consolidated  financial 
statements or operations. 

In  January 2016,  the  FASB  issued  Accounting  Standards  Update  No. 2016-01  to  ASC  825-10,  “Financial 
Instruments – Overall.”  The update amends existing standards regarding certain aspects of recognition and measurement 
of financial assets and financial liabilities.  The amendments in the update establish the following guidance:  (i) 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,  (ii) simplifies  the 
impairment assessment of equity securities without readily determinable fair values by requiring a qualitative assessment, 
(iii) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities 
that are not public business entities, (iv) eliminates the requirement for public business entities to disclose the methods 
and significant assumptions used to estimate fair value that is required to be disclosed for financial instruments measured 
at amortized cost on the balance sheet, (v) requires public business entities to use the exit price notion when measuring 
fair value for disclosure purposes, (vi) 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, (vii) requires separate 
presentation of financial assets and liabilities  by measurement category and form of financial assets on the balance sheet 
or in the accompanying notes to the financial statements, and (viii) clarifies that an entity should evaluate the need to a 
valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other 

42 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

deferred  tax  assets.    The  update  is  effective  for  interim  and  annual  periods  beginning  after  December 15,  2017.    On 
January 1,  2018,  we  adopted  the  provisions  of  ASU  2016-01  The  main  effect  resulting  from  the  adoption  of  the  new 
standards is that beginning on January 1, 2018, equity securities with readily determinable fair values are now reported in 
a single line item on the face of our consolidated statement of condition under the caption, “Equity securities with readily 
determinable fair values.” Additionally, the changes in fair value of the equity securities is now recognized in net income 
and is included in other non-interest expense on the face of our consolidated income statement. Prior to January 1, 2018, 
the equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses included 
in accumulated comprehensive income, net of tax and had a net unrealized loss of $189,000. Other equity securities without 
readily determinable fair values are recorded at cost less any impairment, if any, and included in other investments in our 
consolidated financial statements.     

In  February 2016,  the  FASB  issued  Accounting  Standards  Update  No. 2016-02  to  ASC  820,  “Leases.”    The 
update amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining 
mainly unchanged from current guidance.  The update requires that lessees recognize a lease liability and a right of use 
asset  for  all  leases  (with  the  exception  of  short-term  leases)  at  the  commencement  date  of  the  lease  and  disclose  key 
information about leasing arrangements.  The update is to be applied on a modified retrospective basis for leases existing 
at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements.  
The update is effective for interim and annual periods beginning after December 15, 2018.  In January 2018, the FASB 
issued a proposal that provides an additional transition method that would allow entities to not apply the guidance in the 
update in the comparative periods presented in the consolidated financial statements, but instead recognize a cumulative-
effect adjustment to the opening balance of retained earnings in the period of adoption.  The adoption of the update is not 
expected to have a significant impact to our consolidated financial statements.   

In  June 2016,  the  FASB  issued  Accounting  Standards  Update  No. 2016-13  to  ASC  326,  “Financial 
Instruments – Credit Losses.”  The update amends existing standards for accounting for credit losses for financial assets.  
The update requires that the expected credit losses on the financial instruments held as of the end of the period being 
reported be measured based on historical experience, current conditions, and reasonable and supportable forecasts.  The 
update  also  expands  the  required  disclosures  related  to  significant  estimates  and  judgements  used  in  estimating  credit 
losses,  as  well  as  the  credit  quality  and  underwriting  standards  of  an  organization’s  financial  assets.    The  update  also 
amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit 
deterioration and effective for interim and annual periods beginning after December 15, 2019.  The change in accounting 
method represents a significant difference to current accounting practice over the accounting for credit losses on financial 
assets.  We have formed a task force including key members of the teams that work with the current calculation of the 
allowance for probable loan losses and members representing the corporate accounting and risk management areas.  The 
task force will be working with a plan to develop and implement the changes to current practice with support from third-
party vendors.  We cannot estimate at this time the impact of ASC 326.     

In  January 2017,  the  FASB  issued  Accounting  Standards  Update  No. 2017-04  to  ASC  350,    “Intangibles – 
Goodwill and Other.”  The update amends existing guidance in evaluating goodwill for impairment.  The update requires 
that an entity perform its annual or interim goodwill test by comparing the fair value of a reporting unit with its carrying 
amount, with any impairment charges being recognized as the difference between the fair value and carrying value.  The 
update is intended to standardize the impairment test for all business entities and also reduce the complexity and cost of 
evaluating goodwill for impairment.  The update is effective for any annual or interim goodwill impairment tests in fiscal 
years beginning after December 15, 2019.  The adoption of the update is not expected to have a significant impact to our 
consolidated financial statements. 

In  March 2017,  the  FASB  issued  Accounting  Standards  Update  No. 2017-08  to  ASC  310,  “Receivables – 
Nonrefundable  Fees  and  Other  Costs.”    The  update  amends  existing  guidance  on  the  amortization  period  for  certain 
callable debt securities held at a premium.  The update shortens the amortization period of the premium to the earliest call 
date.  The update is effective for fiscal years beginning after December 15, 2018.  The update is to be applied on a modified

Notes to Consolidated Financial Statements (Continued) 

retrospective  basis  through  a  cumulative-effect  adjustment  to  retained  earnings  as  of  the  beginning  of  the  period  of 
adoption.  The adoption of the update did not have a significant impact to our consolidated financial statements. 

In February 2018, the FASB issued Accounting Standards Update No. 2018-02 to ASC 220, “Income Statement – 
Reporting Comprehensive Income.”  The update amends current guidance surrounding the reclassification of certain tax 
effects from accumulated other comprehensive income.  The update is being issued as a result of the 2017 Tax Cuts and 
Jobs Act and the related impact to comprehensive income as a result of the application of current guidance with respect to 
changes  in  tax  rates.    Under  current  guidance,  entities  must  re-evaluate  the  carrying  value  of  deferred  tax  assets  and 
liabilities and adjust them for the tax effect of the rate change and record that change through earnings.  The result is that 
the tax effects for items that normally would only be recognized in comprehensive income will be recognized through 
earnings and results in stranded tax effects in accumulated other comprehensive income (loss) for the impact of the rate 
change.  The update will allow a reclassification from accumulated other comprehensive income (loss) to retained earnings 
for the stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act.  The update is effective for all entities for fiscal 
years beginning after December 31, 2018.  We adopted the provisions of ASU 2018-02 to ASC 220 in the second quarter 
of 2018. We recorded a one-time reclassification of $5,997,000 between accumulated comprehensive income (loss) and 
retained earnings as a result of the adoption of the accounting standards update. 

In  August 2018,  the  FASB  issued  Accounting  Standards  Update  No. 2018-13  to  ASC  820,  “Fair  Value 
Measurement.”  The update amends the existing guidance surrounding the disclosure of certain fair value measurements.  
The  update  removes  certain disclosures  that  are  no  longer  considered  cost  beneficial, modifies  and, in  some  instances 
clarifies, the specific requirements of certain disclosures and adds disclosure requirements that are identified relevant.  The 
update is effective for fiscal years beginning after December 15, 2019.  The adoption of the update is not expected to have 
a significant impact on our consolidated financial statements.

$3,237,1700 of mortgage-backed securities issued by Fannie Mae and Freddie Mac  

Residential  mortgage-backed  securities  are  securities  issued  by  Freddie  Mac,  Fannie  Mae,  Ginnie  Mae  or 
non-government entities. Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed 
by the U.S. government. Investments in mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully 
guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds 
with  limited  credit  risk, particularly  given  the  placement  of Fannie  Mae  and Freddie  Mac  into  conservatorship by  the 
federal government in early September 2008 and because securities issued by others that are collateralized by residential 
mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities.

The unrealized losses on investments in residential mortgage-backed securities are primarily caused by changes 
in market interest rates. Residential mortgage-backed securities are primarily securities issued by Freddie Mac, Fannie Mae 
and Ginnie Mae. The contractual cash obligations of the securities issued by Ginnie Mae are fully guaranteed by the U.S. 
government.  The  contractual  cash  obligations  of  the  securities  issued  by  Freddie  Mac  and  Fannie  Mae  are  not  fully 
guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds 
with  limited  credit  risk, particularly  given  the  placement  of Fannie  Mae  and Freddie  Mac  into  conservatorship by  the 
federal government in early September 2008 and because securities issued by others that are collateralized by residential 
mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities. The 
decrease in fair value on residential mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae is 
due to market interest rates. We have no intent to sell and more likely than not be required to sell before a market price 
recovery or maturity of the securities; therefore, it is our conclusion that the investments in residential mortgage-backed 
securities issued by Freddie Mac, Fannie Mae and Ginnie Mae are not considered other-than-temporarily impaired. In 
addition,  we  had  a  small  investment  in  non-agency  residential  mortgage-backed  securities  that  had  additional  market 
volatility beyond economically induced interest rate events, which were sold in the first quarter of 2017.  We concluded 
that the investments in non-agency residential mortgage-backed securities were other-than-temporarily impaired due to 
both credit and other than credit issues. No impairment charges were recorded in 2017.  Impairment charges of $354,000 
($230,100, after tax) were recorded in 2016 on the non-agency residential mortgage backed securities. The impairment 
charges represent the credit related impairment on the securities. 

The unrealized losses on investments in other securities are caused by fluctuations in market interest rates. The 
underlying cash obligations of the securities are guaranteed by the entity underwriting the debt instrument. We believe 
that the entity issuing the debt will honor its interest payment schedule, as well as the full debt at maturity. We purchased 
the securities for their economic value. The decrease in fair value is primarily due to market interest rates and not other

factors,  and  because  we  have  no  intent  to  sell  and  will  more  likely  than  not  be  required  to  sell  before  a  market  price 
recovery or maturity of the securities, it is our conclusion that the investments are not considered other-than-temporarily

(4) Allowance for Probable Loan Losses 

The allowance for probable loan losses primarily consists of the aggregate loan loss allowances of the Subsidiary 
Banks. The allowances are established through charges to operations in the form of provisions for probable loan losses. 
Loan losses or recoveries are charged or credited directly to the allowances. The allowance for probable loan losses of 
each Subsidiary Bank is maintained at a level considered appropriate by management, based on estimated probable losses 
in  the  loan  portfolio.  The  allowance  for  probable  loan  losses  is  derived  from  the  following  elements:  (i) allowances 
established on specific impaired loans, which are based on a review of the individual characteristics of each loan, including 
the customer’s ability to repay the loan, the underlying collateral values, and the industry in which the customer operates, 
(ii) allowances  based  on  actual  historical  loss  experience  for  similar  types  of  loans  in  our  loan  portfolio,  and 
(iii) allowances based on general economic conditions, changes in the mix of loans, company resources, border risk and 
credit quality indicators, among other things.  

Our management continually reviews the allowance for loan losses of the Subsidiary Banks using the amounts 
determined from the allowances established on specific impaired loans, the allowance established on quantitative historical 
loss  percentages,  and  the  allowance  based  on  qualitative  data  to  establish  an  appropriate  amount  to  maintain  in  our 
allowance for probable loan losses. Should any of the factors considered by management in evaluating the adequacy of 
the allowance for probable loan losses change, our estimate of probable loan losses could also change, which could affect 
the level of future provisions for probable loan losses. While the calculation of the allowance for probable loan losses 
utilizes management’s best judgment and all information available, the adequacy of the allowance is dependent on a variety 
of factors beyond our control, including, among other things, the performance of the entire loan portfolio, the economy, 
changes in interest rates and the view of regulatory authorities towards loan classifications. 

The loan loss provision is determined using the following methods. On a weekly basis, loan past due reports are 
reviewed by the credit quality committee to determine if a loan has any potential problems and if a loan should be placed 
on our internal classified report. Additionally, our credit department reviews the majority of our loans for proper internal 
classification purposes regardless of whether they are past due and segregates any loans with potential problems for further 
review. The credit department will discuss the potential problem loans with the servicing loan officers to determine any 
relevant issues that were not discovered in the evaluation. Also, an analysis of loans that is provided through examinations 
by regulatory authorities is considered in the review process. After the above analysis is completed, we will determine if 
a  loan  should  be  placed  on  an  internal  classified  report  because  of  issues  related  to  the  analysis  of  the  credit,  credit 
documents, collateral and/or payment history. 

World  and  U.S.  economic  conditions  have  continued  to  improve;  however,  there  remains  some  uncertainty 
created by continued issues with negative demographic trends, weak labor participation rates, enormous government debt, 
excessive regulations, and unfunded entitlement programs that could create a financial crisis.  The impact to the world and 
U.S. economy from these issues is being magnified by a lack of appropriate government action to find solutions to the 
problems.    Economic  risk  factors  are  minimized  by  the  underwriting  standards  of  the  Subsidiary  Banks.  The  general 
underwriting standards encompass the following principles:  (i) the financial strength of the borrower including strong 
earnings,  a  high  net  worth,  significant  liquidity  and  an  acceptable  debt  to  worth  ratio,  (ii) managerial  and  business 
competence, (iii) the ability to repay, (iv) for a new business, projected cash flows, (v) loan to value, (vi) in the case of a 
secondary guarantor, a guarantor financial statement, and (vii) financial and/or other character references.  Although the 
underwriting standards reduce the risk of loss, unique risk factors exist in each type of loan in which the Subsidiary Banks 
invest. 

Commercial and industrial loans are mostly secured by the collateral pledged by the borrower that is directly 
related to the business activities of the company such as accounts receivable and inventory. The ability of the borrower to 
collect accounts receivable, and to turn inventory into sales are risk factors in the repayment of the loan.

Construction and land development loans can carry risk of repayment when projects incur cost overruns, have an 
increase in the price of building materials, encounter zoning and environmental issues, or encounter other factors that may 
affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively impacted when 
the market experiences a deterioration in the value of real estate. Risks specifically related to 1-4 family development loans 
also include the practice by the mortgage industry of more restrictive underwriting standards, which inhibits the buyer 
from obtaining long term financing and excessive housing and lot inventory in the market. 

Commercial  real  estate  loans  demonstrate  a  risk  of  repayment  when  market  values  deteriorate,  the  business 
experiences turnover in key management, the business has an inability to attract or keep occupancy levels stable, or when 
the  market  experiences  an  exit  of  a  specific  business  industry  that  is  significant  to  the  local  economy,  such  as  a 
manufacturing plant. 

First  and  second  lien  residential  1-4  family  mortgage  and  consumer  loan  repayments  may  be  affected  by 

unemployment or underemployment and deteriorating market values of real estate.

The  allowance  for  probable  loan  losses  is  a  reserve  established  through  a  provision  for  probable  loan  losses 
charged  to  expense,  which  represents  management’s  best  estimate  of  probable  loan  losses  when  evaluating  loans 
(i) individually or (ii) collectively. The decrease in the provision for probable loan losses charged to expense for the years 
ended December 31, 2018 and December 31, 2017  can be attributed to a decrease in the historical loss experience in the 
commercial category of the calculation.  As discussed in prior periods, charge-offs increased from historical levels due to 
the  deterioration of  one relationship  that  was  secured by multiple  pieces  of  transportation  equipment  beginning  in  the 
fourth  quarter  of  2014.    We  use  a  three-year  historical  charge-off  experience  in  the  calculation,  therefore,  as  those 
charge-offs are eliminated from the calculation, the allowance for probable loan losses is impacted.  As fluctuations occur 
in historical loss factors, management evaluates the need to adjust the qualitative factors used in the calculation to properly 
reflect probable loan losses.  The increase in losses charged to the allowance for probable loan losses for the year ended 
December 31, 2016 can be attributed to further deterioration in the previously identified and charged down relationship 
primarily secured by multiple pieces of transportation equipment. In March 2016, litigation against the management of the 
borrower was filed in the State of Nevada, resulting in a going concern issue with the borrower’s operations and the future 
use of the transportation equipment pledged as collateral on the relationship. As a result, management, in accordance with 
its credit review procedures, re-evaluated the collateral values on the equipment in light of the new circumstances and 
reduced the collateral values accordingly, resulting in a further charge-down of the relationship of approximately $19.4 
million, which is included in the losses charged to the allowance in the commercial category in the table detailing the year 
ended December 31, 2016 activity.

The decrease in loans individually evaluated for impairment at December 31, 2018 compared to December 31, 
2017, can be attributed to the foreclosure on a relationship primarily secured by a water park and the foreclosure of the 
collateral  on  a  relationship  secured  by  multiple  pieces  of  transportation  equipment.    The  foreclosure  of  the  collateral 
securing the two relationships is also impacting the balances reported as impaired loans in the following tables. Loans 
accounted for on a non-accrual basis at December 31, 2018, 2017 and 2016 amounted to $15,791,000, $54,730,000 and 
$37,245,000, respectively. The effect of such non-accrual loans reduced interest income by approximately $1,119,000, 
$977,000  and $2,461,000  for  the  years  ended December 31, 2018,  2017  and 2016,  respectively. Amounts  received on 
non-accruals are applied, for financial accounting purposes, first to principal and then to interest after all principal has 
been collected. Accruing loans contractually past due 90 days or more as to principal or interest payments at December 31, 
2018,  2017  and  2016  amounted  to  approximately  $40,674,000,  $7,257,000  and  $5,226,000,  respectively  and  can  be 
attributed to a relationship that is secured by multiple pieces of real property on which car dealerships are operated.

Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan 
agreement will not be collected. We have identified these loans through our normal loan review procedures. Impaired 
loans are measured based on (i) the present value of expected future cash flows discounted at the loan’s effective interest 
rate;  (ii) the  loan’s  observable  market  price;  or  (iii) the  fair  value  of  the  collateral  if  the  loan  is  collateral  dependent. 
Substantially all of our impaired loans are measured at the fair value of the collateral. In limited cases, we may use other 
methods to determine the level of impairment of a loan if such loan is not collateral dependent.

due to our long-standing practices that emphasize secured lending with strong collateral positions and guarantor support. 
Management is likewise confident the reserve for probable loan losses is adequate.  

Management  recognizes  the  risks  associated  with  these  impaired  loans.    However,  management's  decision  to 
place loans in this category does not necessarily mean that losses will occur. In the current environment, troubled loan 
management  can  be  protracted  because  of  the  legal  and  process  problems  that  delay  the  collection  of  an  otherwise 
collectible loan.  Additionally, management believes that the collateral related to these impaired loans and/or the secondary 
support from guarantors mitigates the potential for losses from impaired loans.     

The following table details loans accounted for as “troubled debt restructuring,” segregated by loan class.  Loans 

accounted for as troubled debt restructuring are included in impaired loans.

The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss, as 
well as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial and industrial or real 
estate loans are generally considered by management to represent a loss, in whole or part, when an exposure beyond any 
collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s 
financial condition and general economic conditions in the borrower’s industry. Generally, unsecured consumer loans are 
charged-off when 90 days past due. 

While management considers that it is generally able to identify borrowers with financial problems reasonably 
early and to monitor credit extended to such borrowers carefully, there is no precise method of predicting loan losses. The 
determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an 
exercise of judgment. Similarly, the determination of the adequacy of the allowance for probable loan losses can be made 
only  on  a  subjective  basis.  It  is  the  judgment  of  our  management  that  the  allowance  for  probable  loan  losses  at 
December 31, 2018 and December 31, 2017, was adequate to absorb probable losses from loans in the portfolio at that 
date.

The  increase  in  the  commercial  real  estate:  farmland  and  commercial  in  the  90  days  and  greater  category  at 
December 31, 2018 compared to December 31, 2017 can be attributed to a relationship that is secured by multiple pieces 
of real property on which car dealerships are operated.  The relationship remained on accrual since we had a court approved 
debtor in possession plan that provided that the sponsors of the plan would assume full responsibility for the plan, including 
accrued and unpaid interest.  Our internal classified report is segregated into the following categories: (i) “Special Review 
Credits,” (ii) “Watch List—Pass Credits,” or (iii) “Watch List—Substandard Credits.” The loans placed in the “Special 
Review Credits” category reflect our opinion that the loans reflect potential weakness which require monitoring on a more 
frequent basis. The “Special Review Credits” are reviewed and discussed on a regular basis with the credit department and 
the lending staff to determine if a change in category is warranted. The loans placed in the “Watch List—Pass Credits” 
category reflect our opinion that the credit contains weaknesses which represent a greater degree of risk, which warrant 
“extra attention.” The “Watch List—Pass Credits” are reviewed and discussed on a regular basis with the credit department 
and the lending staff to determine if a change in category is warranted. The loans placed in the “Watch List—Substandard 
Credits” classification are considered to be potentially inadequately protected by the current sound worth and debt service 
capacity of the borrower or of any pledged collateral. These credit obligations, even if apparently protected by collateral 
value, have shown defined weaknesses related to adverse financial, managerial, economic, market or political conditions 
which may jeopardize repayment of principal and interest. Furthermore, there is the possibility that we could sustain some 
future loss if such weaknesses are not corrected. For loans that are classified as impaired, management evaluates these 
credits in accordance with the provision of. ASC 310-10, “Receivables,” and, if deemed necessary, a specific reserve is 
allocated to the credit. The specific reserve allocated under ASC 310-10, is based on (i) the present value of expected 
future cash flows discounted at the loan’s effective interest rate; (ii) the loan’s observable market price; or (iii) the fair

value  of  the  collateral  if  the  loan  is  collateral  dependent.  Substantially  all  of  our  loans  evaluated  as  impaired  under 
ASC 310-10  are  measured  using  the  fair  value  of  collateral  method.  In  limited  cases,  we  may  use  other  methods  to 
determine the specific reserve of a loan under ASC 310-10 if such loan is not collateral dependent. 

The allowance based on historical loss experience on our remaining loan portfolio, which includes the “Special 
Review Credits,” “Watch List—Pass Credits,” and “Watch List—Substandard Credits” is determined by segregating the 
remaining  loan  portfolio  into  certain  categories  such  as  commercial  loans,  installment  loans,  international  loans,  loan 
concentrations and overdrafts. Installment loans are then further segregated by number of days past due. A historical loss 
percentage, adjusted for (i) management’s evaluation of changes in lending policies and procedures, (ii) current economic 
conditions in the market area served, (iii) other risk factors, (iv) the effectiveness of the internal loan review function, 
(v) changes in loan portfolios, and (vi) the composition and concentration of credit volume is applied to each category. 
Each category is then added together to determine the allowance allocated under ASC 450-20. 

A summary of the loan portfolio by credit quality indicator by loan class is as follows:

The increase in special review credits in the commercial real estate:  farmland and commercial for December 31, 
2018 compared to December 31, 2017 can be attributed to a relationship secured by children’s learning centers reclassified 
from the Pass category.  The increase in Watch-List Pass commercial credits can be attributed to the reclassification of a 
relationship in the oil and gas production business from Watch-List Substandard.  The decrease in Watch-List Substandard

for December 31, 2018 can be attributed to the payoff of a relationship secured by barges used in the transportation of 
petroleum  products,  the  reclassification  of  a  relationship  secured  by  accounts  receivable  to  Pass  and  the  previously 
mentioned reclassification of the relationship in the oil and gas production business to Watch-List Pass.  The increase in 
Watch-List  Substandard  commercial  credits  for  December 31, 2018  can be  attributed  to  a  relationship  secured  by real 
property on which car dealerships are operated from the Pass category.  The decrease in Watch-List Impaired credits in 
the commercial real estate:  farmland and commercial at December 31, 2018 can be attributed to the foreclosure of a loan 
relationship primarily secured by a water park.

on an annual basis.  Two amortizing advances are outstanding at December 31, 2018 in the amounts of $3,200,000 and $8,490,000 and mature in 
December 2033 and November 2033, respectively.  The amortization on the amortizing long-term advances totals approximately $179,000 per year 
for each of the next five years.  Long-term advances outstanding at December 31, 2017 mature in the following increments:  $100,000,000 in 
November 2027 and $150,000,000 in December 2027 and are callable by the FHLB on a quarterly basis.   

(10) Junior Subordinated Deferrable Interest Debentures 

We have formed six statutory business trusts under the laws of the State of Delaware for the purpose of issuing 
trust preferred securities. These statutory business trusts (the “Trusts”) have each issued Capital and Common Securities 
and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) we issued. 
As of December 31, 2018 and December 31, 2017, the principal amount of debentures outstanding totaled $160,416,000.  

The Debentures are subordinated and junior in right of payment to all our present and future senior indebtedness 
(as defined in the respective indentures) and are pari passu with one another. The interest rate payable on, and the payment 
terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and 
Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the 
Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the 
Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive 
quarterly  periods  on  Trusts  VI,  VIII,  IX,  X,  XI  and  XII.  If  interest  payments  on  any  of  the  Debentures  are  deferred, 
distributions on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption 
prior to maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory 
bodies. 

For financial reporting purposes, the Trusts are treated as investments and not consolidated in the consolidated 
financial  statements.  Although  the  Capital  Securities  issued  by  each of  the Trusts  are  not  included  as  a  component  of 
shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory 
purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 
capital up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that exceeds the 25% threshold 
would  qualify  as  Tier 2  capital.  At  December 31,  2018  and  December 31,  2017,  the  total  $160,416,000  of  the  Capital 
Securities outstanding qualified as Tier 1 capital.

(11) Earnings per Share (“EPS”) 

Basic EPS is calculated by dividing net income by the weighted average number of common shares outstanding. 
The  computation  of  diluted  EPS  assumes  the  issuance  of  common  shares  for  all  dilutive  potential  common  shares 
outstanding  during  the  reporting  period.  The  calculation  of  the  basic  EPS  and  the  diluted  EPS  for  the  years  ended

(12) Employees’ Profit Sharing Plan 

We  have  a  deferred  profit  sharing  plan  for  full-time  employees  with  a  minimum  of  one  year  of  continuous 
employment. Our annual contribution to the plan is based on a percentage, as determined by our Board of Directors, of 
income  before  income  taxes,  as  defined,  for  the  year.  Allocation  of  the  contribution  among  officers  and  employees’ 
accounts is based on length of service and amount of salary earned. Profit sharing costs of $3,850,000 $3,750,000 and 
$3,650,000 were charged to income for the years ended December 31, 2018, 2017, and 2016, respectively. 

(13) International Operations 

We provide international banking services for our customers through our Subsidiary Banks. Neither we nor our 
Subsidiary Banks have facilities located outside the United States. International operations are distinguished from domestic 
operations based upon the domicile of the customer. 

Because the resources we employ are common to both international and domestic operations, it is not practical to 

determine net income generated exclusively from international activities.

On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was signed into law.  The Tax Act materially 
changes U.S. corporate income tax rates, among other things.  We were in a net deferred tax liability position at the time 
the Tax Act was enacted and subsequently revalued the carrying value of the net deferred liability and its components to 
the new 21% effective tax rate.  The change in the tax rate resulted in a net benefit to us of $4,786,000 and was included 
as a reduction to income tax expense in the consolidated income statement.

(15) Stock Options 

On April 5, 2012, the Board of Directors adopted the 2012 International Bancshares Corporation Stock Option 
Plan (the “2012 Plan”). There are 800,000 shares available for stock option grants under the 2012 Plan. Under the 2012 
Plan, both qualified incentive stock options (“ISOs”) and non-qualified stock options (“NQSOs”) may be granted. Options 
granted  may  be  exercisable  for  a  period  of  up  to  10 years  from  the  date  of  grant,  excluding  ISOs  granted  to  10% 
shareholders, which may be exercisable for a period of up to only five years. As of December 31, 2018, 10,700 shares 
were available for future grants under the 2012 Plan. 

The  fair  value  of  each  option  award  granted  under  the  plan  is  estimated  on  the  date  of  grant  using  a 
Black-Scholes-Merton option valuation model that uses the assumptions noted in the following table. Expected volatility 
is based on the historical volatility of the price of our stock. We use historical data to estimate the expected dividend yield 
and  employee  termination  rates  within  the  valuation  model.  The  expected  term  of  options  is  derived  from  historical 
exercise behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield 
curve in effect at the time of grant.

(16) Long Term Restricted Stock Units  

As a former participant in the Troubled Asset Relief Program Capital Purchase Program (the “CPP”) we were 
subject to certain compensation restrictions, including a prohibition on the payment or accrual of any bonuses to certain 
officers and employees except for awards of CPP-compliant long- term restricted stock and stock units. 

On  December 18,  2009,  our  board  of  directors  (the  “Board”)  adopted  the  2009  International  Bancshares 
Corporation Long-Term Restricted Stock Unit Plan (the “Plan”) to give us additional flexibility in the compensation of 
our officers, employees, consultants and advisors in compliance with all applicable laws and restrictions. 

The  Plan  authorizes  us  to  issue  Restricted  Stock  Units  (“RSUs”)  to  our  officers,  employees,  consultants  and 
advisors.  On December 18, 2009, pursuant to the Plan, the Board adopted resolutions creating the Long-Term Restricted 
Stock Unit Plan Committee to administer the Plan. RSUs issued under the Plan are not equity and are payable only in cash. 
The Plan provides for both the issuance of CPP-compliant long-term RSUs as well as RSUs that are not CPP-compliant.  
No grants have been made under the Plan since December 2012 and there are currently no outstanding grants under the 
Plan.  

(17) Commitments, Contingent Liabilities and Other Matters 

We lease portions of our banking premises and equipment under operating leases. Total rental expense for the 
years ended December 31, 2018, 2017 and 2016 were approximately $5,257,000, $5,258,000 and $5,870,000, respectively.

Cash  of  approximately  $115,721,000  and  $116,129,000  at  December 31,  2018  and  2017,  respectively,  was 

maintained to satisfy regulatory reserve requirements. 

We are involved in various legal proceedings that are in various stages of litigation. We have determined, based 
on discussions with our counsel that any material loss in such actions, individually or in the aggregate, is remote or the 
damages sought, even if fully recovered, would not be considered material to our consolidated statements of condition and 
related  statements  of  income,  comprehensive  income,  shareholders’  equity  and  cash  flows.  However,  many  of  these 
matters are in various stages of proceedings and further developments could cause management to revise its assessment of 
these matters. 

(18) Transactions with Related Parties 

In  the  ordinary  course  of  business,  the  Subsidiary  Banks  make  loans  to  our  directors  and  executive  officers, 
including their affiliates, families and companies in which they are principal owners. In the opinion of management, these 
loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for 
comparable transactions with other persons and do not involve more than normal risk of collectability or present other 
unfavorable features. The aggregate amounts receivable from such related parties amounted to approximately $33,042,000 
and $27,626,000 at December 31, 2018 and 2017, respectively. 

(19) Financial Instruments with Off-Statement of Condition Risk and Concentrations of Credit Risk 

In the normal course of business, the Subsidiary Banks are party to financial instruments with off-statement of 
condition risk to meet the financing needs of their customers. These financial instruments include commitments to their 
customers.  These  financial  instruments  involve,  to  varying  degrees,  elements  of  credit  risk  in  excess  of  the  amounts 
recognized  in the  consolidated  statement  of  condition.  The  contract  amounts  of  these  instruments  reflect  the  extent of 
involvement the Subsidiary Banks have in particular classes of financial instruments. At December 31, 2018, the following 
financial amounts of instruments, whose contract amounts represent credit risks, were outstanding:

We enter into a standby letter of credit to guarantee performance of a customer to a third party. These guarantees 
are primarily issued to support public and private borrowing arrangements. The credit risk involved is represented by the 
contractual amounts of those instruments. Under the standby letters of credit, we are required to make payments to the 
beneficiary of the letters of credit upon request by the beneficiary so long as all performance criteria have been met. At 
December 31, 2018, the maximum potential amount of future payments is approximately $111,229,000. At December 31, 
2018, the fair value of these guarantees is not significant. Unsecured letters of credit totaled approximately $42,729,000 
and $35,409,000 at December 31, 2018 and 2017, respectively. 

We enter into commercial letters of credit on behalf of our customers which authorize a third party to draw drafts 
upon us up to a stipulated amount and with specific terms and conditions. A commercial letter of credit is a conditional 
commitment on our part to provide payment on drafts drawn in accordance with the terms of the commercial letter of 
credit. 

The Subsidiary Banks’ exposure to credit loss in the event of nonperformance by the other party to the above 
financial instruments is represented by the contractual amounts of the instruments. The Subsidiary Banks use the same 
credit policies in making commitments and conditional obligations as they do for on-statement of condition instruments. 
The  Subsidiary  Banks  control  the  credit  risk  of  these  transactions  through  credit  approvals,  limits  and  monitoring 

67

procedures. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any 
condition established in the contract. Commitments generally have fixed expiration dates normally less than one year or 
other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire 
without  being  drawn  upon,  the  total  commitment  amounts  do  not  necessarily  represent  future  cash  requirements.  The 
Subsidiary Banks evaluate each customer’s credit-worthiness on a case-by-case basis. The amount of collateral obtained, 
if deemed necessary by the Subsidiary Banks upon extension of credit, is based on management’s credit evaluation of the 
customer.  Collateral  held  varies,  but  may  include  residential  and  commercial  real  estate,  bank  certificates  of  deposit, 
accounts receivable and inventory. 

The Subsidiary Banks make commercial, real estate and consumer loans to customers principally located in South, 
Central and Southeast Texas and the State of Oklahoma. Although the loan portfolio is diversified, a substantial portion 
of its debtors’ ability to honor their contracts is dependent upon the economic conditions in these areas, especially in the 
real estate and commercial business sectors. 

(20) Capital Requirements 

On December 23, 2008, as part of the Troubled Asset Relief Program Capital Purchase Program of the United 
States Department of the Treasury (“Treasury”), we issued to the Treasury a warrant to purchase 1,326,238 shares of our 
common stock at a price per share of $24.43 and with a term of ten years (the “Warrant”).  

On June 12, 2013, the U.S. Treasury sold the Warrant to a third party. On September 19, 2018, we entered into 
an  agreement  to  repurchase  the  Warrant  from  the  third  party  at  an  aggregate  purchase  price  of  $29,005,000,  which 
transaction  was  consummated  in  the  third  quarter  of  2018.  The  repurchase  of  the  outstanding  Warrant  eliminates  any 
restrictions on certain shareholder distributions or payment of cash dividends in excess of $0.33 per semi-annual period 
that would have impacted the exercise price of the Warrant while it remained outstanding. 

Bank regulatory agencies limit the amount of dividends, which the Subsidiary Banks can pay, without obtaining 
prior  approval  from  such  agencies.  At  December 31,  2018,  the  Subsidiary  Banks  could  pay  dividends  of  up  to 
$768,900,000  without  prior  regulatory  approval  and  without  adversely  affecting  their  “well-capitalized”  status  under 
regulatory  capital  rules  in  effect  at  December 31,  2018.  In  addition  to  legal  requirements,  regulatory  authorities  also 
consider the adequacy of the Subsidiary Banks’ total capital in relation to their deposits and other factors. These capital 
adequacy  considerations  also  limit  amounts  available for payment  of dividends. We historically  have not  allowed any 
Subsidiary Bank to pay dividends in such a manner as to impair its capital adequacy. 

We and the Subsidiary Banks are subject to various regulatory capital requirements administered by the federal 
banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional 
discretionary actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial 
statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet 
specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-statement of condition 
items  as  calculated  under  regulatory  accounting  practices.  Our  capital  amounts  and  classification  are  also  subject  to 
qualitative judgments by the regulators about components, risk weightings, and other factors. 

Current  quantitative  measures  established  by  regulation  to  ensure  capital  adequacy  require  us  to  maintain 
minimum amounts and ratios (set forth in the table on the following page) of Total and Tier 1 capital to risk-weighted 
assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2018, that we met all capital 
adequacy requirements to which we are subject. 

In July 2013, the Federal Deposit Insurance Corporation (“FDIC”) and other regulatory bodies established a new, 
comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both 
the quantity and quality of capital held by banking organizations. The final rules are a result of the implementation of the 

68 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

BASEL III capital reforms and various Dodd-Frank Act related capital provisions. Consistent with the Basel international 
framework, the rules include a new minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% 
and a CET1 capital conservation buffer of 2.5% of risk-weighted assets.  The capital conservation buffer began phasing-in 
on January 1, 2016 at .625% and increased each year until January 1, 2019, when we were required to have a 2.5% capital 
conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon 
full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and 
include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the new rules 
emphasize CET1 capital and implements strict eligibility criteria for regulatory capital instruments. The new rules also 
improve  the  methodology  for  calculating  risk-weighted  assets  to  enhance  risk  sensitivity.  The  rules  were  subject  to  a 
four-year phase in period for mandatory compliance and we were required to begin to phase in the new rules beginning on 
January 1, 2015.  Management believes, as of December 31, 2018, that we will meet all capital adequacy requirements 
once the capital conservation is fully phased-in.  

On November 21, 2017, the OCC, the Federal Reserve and the FDIC finalized a proposed rule that extends the 
current treatment under the regulatory capital rules for certain regulatory capital deductions and risk weights and certain 
minority interest requirements, as they apply to banking organizations that are not subject to the advanced approaches 
capital rules.  Effective January 1, 2018, the rule also pauses the full transition to the Basel III treatment of mortgage 
servicing assets, certain deferred tax assets, investments in the capital of unconsolidated financial institutions and minority 
interests.  The agencies are also considering whether to make adjustments to the capital rules in response to CECL (the 
FASB Standard relating to current expected credit loss) and its potential impact on regulatory capital. 

On December 7, 2017, the Basel Committee on Banking Supervision unveiled the latest round of its regulatory 
capital framework, commonly called “Basel IV.”  The framework makes changes to the capital framework first introduced 
as “Basel III” in 2010.  The committee targeted 2022-2027 as the timeframe for implementation by regulators in individual 
countries, including the U.S. federal bank regulatory agencies (after notice and comment). 

The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. 
Banking institutions with a ratio of CET1 capital to risk-weighted assets above the minimum but below the conservation 
buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. 

As of December 31, 2018, our capital levels exceed all capital adequacy requirements under the Basel III Capital 
Rules as currently applicable to us. Based on the ratios presented below, capital levels as of December 31, 2018 exceed 
the minimum levels necessary to be considered “well capitalized.”   

On  May 24,  2018,  the  EGRRCPA  was  enacted  and,  among  other  things,  it  includes  a  simplified  capital  rule 
change which effectively exempts banks with assets of less than $10 billion that exceed the “community bank leverage 
ratio,” from all risk-based capital requirements, including Basel III and its predecessors. The federal banking agencies 
must establish the “community bank leverage ratio” (a ratio of tangible equity to average consolidated assets) between 8% 
and 10% before community banks can begin to take advantage of this regulatory relief provision. Some of the Subsidiary 
Banks, with assets of less than $10 billion, may qualify for this exemption. Additionally, under the EGRRCPA, qualified 
bank holding companies with assets of up to $3 billion (currently $1 billion) will be eligible for the Federal Reserve’s 
Small Bank Holding Company Policy Statement, which eases limitations on the issuance of debt by holding companies. 
On August 28, 2018, the Federal Reserve issued an interim final rule expanding the applicability of its Small Bank Holding 
Company Policy Statement. While holding companies that meet the conditions of the policy statement are excluded from 
consolidated capital requirements, their depository institutions continue to be subject to minimum capital requirements. 
Finally, for banks that continue to be subject to the risk-based capital rules of Basel III (e.g., 150%), certain commercial 
real estate loans that were formally classified as high volatility commercial real estate 31 (“HVCRE”) will not be subject 
to heightened risk weights if they meet certain criteria. Also, while acquisition, development, and construction (“ADC”) 
loans  will  generally  be  subject  to  heightened  risk  weights,  certain  exceptions  will  apply.  On  September 18,  2018,  the 
federal banking agencies issued a proposed rule modifying the agencies’ capital rules for HVCRE.

Notes to Consolidated Financial Statements (Continued) 

As  of  December 31,  2018,  the  most  recent  notification  from  the  Federal  Deposit  Insurance  Corporation 
categorized all the Subsidiary Banks as well-capitalized under the regulatory framework for prompt corrective action. To 
be categorized as “well-capitalized,” we must maintain minimum Total risk-based, Tier 1 risk based, and Tier 1 leverage 
ratios as set forth in the table. There are no conditions or events since that notification that management believes have 
changed our categorization as well-capitalized. 

In December 2018, the federal bank regulators issued a final rule that would provide an optional three-year phase-
in  period  for  the  day-one  regulatory  capital  effects  of  the  adoption  of  ASU  2016-13  to  ASC  326  “Financial 
Instruments – Credit Losses,” as amended, on January 1, 2020.

ASC  Topic  820,  “Fair  Value  Measurements  and  Disclosures”  (“ASC  820”)  defines  fair  value,  establishes  a 
framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value 
measurements. ASC 820 applies to all financial instruments that are being measured and reported on a fair value basis. 
ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants at the measurement date; it also establishes a fair value hierarchy that prioritizes 
the inputs used in valuation methodologies into the following three levels: 

•  Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities. 
•  Level 2  Inputs—Observable  inputs  other  than  Level 1  prices,  such  as  quoted  prices  for  similar  assets  or 
liabilities,  quoted  prices  in  markets  that  are  not  active;  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 Inputs—Unobservable inputs that are supported by little or no market activity and that are significant 
to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose 
value is determined using pricing models, discounted cash flow methodologies, or other valuation techniques, 
as well as instruments for which the determination of fair value requires significant management judgment 
or estimation.

For the years ended December 31, 2018 and December 31, 2017, debt investment securities available-for-sale are 
classified within Level 2 of the valuation hierarchy.  Equity securities with readily determinable fair values are classified 
within Level 1. For debt securities classified as Level 2 in the fair value hierarchy, we obtain fair value measurements 
from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes,

Certain financial instruments are measured at fair value on a nonrecurring basis. They 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).

During 
Period 

Our assets measured at fair value on a non-recurring basis are limited to impaired loans and other real estate 
owned.  Impaired loans are classified within Level 3 of the valuation hierarchy.  The fair value of impaired loans is derived 
in  accordance  with  FASB  ASC  310,  “Receivables”.    Impaired  loans  are  primarily  comprised  of  collateral-dependent 
commercial loans.   Understanding that as the primary sources of loan repayments decline, the secondary repayment source 
comes  into  play  and  correctly  evaluating  the  fair  value  of  that  secondary  source,  the  collateral,  becomes  even  more 
important.  Re-measurement of the impaired loan to fair value is done through a specific valuation allowance included in 
the allowance for probable loan losses.  The fair value of impaired loans is based on the fair value of the collateral, as 
determined through either an appraisal or evaluation process.  The basis for our appraisal and appraisal review process is 
based  on  regulatory  guidelines  and  strives  to  comply  with  all  regulatory  appraisal  laws,  regulations  and  the  Uniform 
Standards of Professional Appraisal Practice. All appraisals and evaluations are “as is” (the property’s highest and best 
use) valuations based on the current conditions of the property/project at that point in time.  The determination of the fair 
value  of  the  collateral  is  based  on  the  net  realizable  value,  which  is  the  appraised  value  less  any  closing  costs,  when 
applicable.  As of December 31, 2018, we had approximately $14,306,000 of impaired commercial collateral dependent 
loans, of which approximately $10,911,000 had an appraisal performed within the immediately preceding twelve months

and  of  which  approximately  $0  had  an  evaluation  performed  within  the  immediately  preceding  twelve  months.  As  of 
December 31,  2017,  we  had  approximately  $53,267,000  of  impaired  commercial  collateral  dependent  loans,  of  which 
approximately $18,585,000 had an appraisal performed within the immediately preceding twelve months and of which 
approximately $0 had an evaluation performed within the immediately preceding twelve months. 

The determination to either seek an appraisal or to perform an evaluation begins in weekly credit quality meetings, 
where  the  committee  analyzes  the  existing  collateral  values  of  the  impaired  loans  and  where  obsolete  appraisals  are 
identified.  In order to determine whether we would obtain a new appraisal or perform an internal evaluation to determine 
the fair value of the collateral, the credit committee reviews the existing appraisal to determine if the collateral value is 
reasonable in view of the current use of the collateral and the economic environment related to the collateral.  If the analysis 
of the existing appraisal does not find that the collateral value is reasonable under the current circumstances, we would 
obtain a new appraisal on the collateral or perform an internal evaluation of the collateral.  The ultimate decision to get a 
new  appraisal  rests  with  the  independent  credit  administration  group.    A  new  appraisal  is  not  required  if  an  internal 
evaluation, as performed by in-house experts, is able to appropriately update the original appraisal assumptions to reflect 
current market conditions and provide an estimate of the collateral’s market value for impairment analysis.  The internal 
evaluations must be in writing and contain sufficient information detailing the analysis, assumptions and conclusions and 
they must support performing an evaluation in lieu of ordering a new appraisal. 

Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other 
real estate owned is carried at the lower of the recorded investment in the property or its fair value less estimated costs to 
sell such property (as determined by independent appraisal) within Level 3 of the fair value hierarchy. Prior to foreclosure, 
the  value  of  the  underlying  loan  is  written  down  to  the  fair  value  of  the  real  estate  to  be  acquired  by  a  charge  to  the 
allowance for probable loan losses, if necessary. The fair value is reviewed periodically and subsequent write downs are 
made accordingly through a charge to operations. Other real estate owned is included in other assets on the consolidated 
financial  statements.  For  the  twelve  months  ended  December 31,  2018,  December 31,  2017  and  December 31,  2016, 
respectively we recorded approximately $170,000, $30,000 and $381,000 in charges to the allowance for probable loan 
losses in connection with loans transferred to other real estate owned. For the twelve months ended December 31, 2018, 
December 31,  2017  and  December 31,  2016,  respectively,  we  recorded  approximately  $3,071,000,  $710,000  and 
$2,351,000 in adjustments to fair value in connection with other real estate owned. 

The  fair  value  estimates,  methods,  and  assumptions  for  our  financial  instruments  at  December 31,  2018  and 

December 31, 2017 are outlined below. 

Cash and Cash Equivalents 

For these short-term instruments, the carrying amount is a reasonable estimate of fair value. 

Investment securities held-to-maturity 

The carrying amounts of investments held-to-maturity approximate fair value. 

Investment Securities 

For  debt  investment  securities,  which  include  U.S.  Treasury  securities,  obligations  of  other  U.S.  government 
agencies, obligations of states and political subdivisions and mortgage pass through and related securities, fair values are 
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. See disclosures of fair 
value of investment securities in Note 2.

Notes to Consolidated Financial Statements (Continued) 

Loans 

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by 
type such as commercial, real estate and consumer loans as outlined by regulatory reporting guidelines. Each category is 
segmented into fixed and variable interest rate terms and by performing and non-performing categories. 

For variable rate performing loans, the carrying amount approximates the fair value. For fixed rate performing 
loans,  except  residential  mortgage  loans,  the  fair  value  is  calculated  by  discounting  scheduled  cash  flows  through  the 
estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. 
For  performing  residential  mortgage  loans,  fair  value  is  estimated  by  discounting  contractual  cash  flows  adjusted  for 
prepayment estimates using discount rates based on secondary market sources or the primary origination market. Fixed 
rate performing loans are within Level 3 of the fair value hierarchy. At December 31, 2018 and December 31, 2017, the 
carrying amount of fixed rate performing loans was $1,515,437,000 and $1,505,531,000, respectively, and the estimated 
fair value was $1,469,231,000 and $1,454,434,000, respectively. 

Accrued Interest 

The carrying amounts of accrued interest approximate fair value. 

Deposits 

The fair value of deposits with no stated maturity, such as non-interest bearing demand deposit accounts, savings 
accounts and interest bearing demand deposit accounts, was equal to the amount payable on demand as of December 31, 
2018 and December 31, 2017. The fair value of time deposits is based on the discounted value of contractual cash flows. 
The discount  rate  is  based on  currently  offered  rates.  Time  deposits  are  within  Level 3 of  the  fair  value  hierarchy.  At 
December 31,  2018  and  December 31,  2017,  the  carrying  amount  of  time  deposits  was  $1,973,468,000  and 
$2,056,506,000, respectively, and the estimated fair value was $1,976,156,000 and $2,058,621,000, respectively. 

Securities Sold Under Repurchase Agreements 

Securities sold under repurchase agreements include both short and long-term maturities. Due to the contractual 
terms  of  the  short-term  instruments,  the  carrying  amounts  approximated  fair  value  at  December 31,  2018  and 
December 31,  2017.  The  fair  value  of  the  long-term  instruments  is  based  on  established  market  spread  using  option 
adjusted spread methodology. Long-term repurchase agreements are within Level 3 of the fair value hierarchy. The only 
remaining long-term repurchase agreement  outstanding matured in the first quarter of 2018 and was not renewed.  At 
December 31, 2017 the carrying amount of long-term repurchase agreements was $100,000,000 and the estimated fair 
value was $99,504,000. 

Junior Subordinated Deferrable Interest Debentures 

We  currently  have  floating  rate  junior  subordinated  deferrable  interest  debentures  outstanding.  Due  to  the 
contractual terms of the floating rate junior subordinated deferrable interest debentures, the carrying amounts approximated 
fair value at December 31, 2018 and December 31, 2017. 

Other Borrowed Funds 

We currently have short and long-term borrowings issued from the Federal Home Loan Bank (“FHLB”). Due to 
the contractual terms of the short-term borrowings, the carrying amounts approximated fair value at December 31, 2018 
and December 31, 2017. The long-term borrowings outstanding at December 31, 2018 and December 31, 2017 are fixed-
rate borrowings and the fair value is based on established market spreads for similar types of borrowings.  The fixed-rate 

75 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

long-term borrowings are included in Level 2 of the fair value hierarchy.  At December 31, 2018, and December 31, 2017 
the carrying amount of the fixed-rate long-term FHLB borrowings was $436,690,000 and $250,000,000, respectively and 
the estimated fair value was $436,238,000 and $249,728,000 respectively.   

Commitments to Extend Credit and Letters of Credit 

Commitments to extend credit and fund letters of credit are principally at current interest rates and therefore the 

carrying amount approximates fair value. 

Limitations 

Fair value estimates are made at a point in time, based on relevant market information and information about the 
financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one 
time of our entire holdings of a particular financial instrument. Because no market exists for a significant portion of our 
financial  instruments,  fair  value  estimates  are  based  on  judgments  regarding  future  expected  loss  experience,  current 
economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective 
in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. 
Changes in assumptions could significantly affect the estimates. 

Fair  value  estimates  are  based  on  existing  on-and  off-statement  of  condition  financial  instruments  without 
attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered 
financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include 
the bank premises and equipment and core deposit value. In addition, the tax ramifications related to the effect of fair value 
estimates have not been considered in the above estimates.
