CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES

The Bank has made no significant changes in its critical accounting policies and significant estimates from those disclosed in its 2018 Annual Report on Form 10-K.

Accounting and Reporting Developments

In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This new standard significantly changes how entities will measure credit losses for virtually all financial assets. The standard replaces today’s “incurred loss” approach with an “expected loss” model for instruments such as loans and held-to-maturity (“HTM”) securities that are measured at amortized cost. The standard requires credit losses relating to available-for-sale (“AFS”) debt securities to be recorded through an allowance rather than a reduction of the carrying amount and replaces the historically required other-than-temporary impairment (“OTTI”) analysis. It also changes the accounting for purchased credit-impaired debt securities and loans. The standard retains many of the current disclosure requirements in U.S. generally accepted accounting principles (“GAAP”) and expands other disclosure requirements. The new guidance is effective for calendar year-end public companies beginning January 1, 2020.

5

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

Our implementation team, led jointly by Credit, Treasury, and the Corporate Controller’s group, has developed models to meet the new standard that are being validated. We have started to analyze the results of our models. Next steps include establishing and testing controls, further challenging model results, and finalizing the qualitative allowance process and disclosures.

Based upon our modeling-to-date, we expect more volatility in the credit loss estimate and less comparability among banks when this new standard becomes effective. Comparability will be impacted by, among other items, varying expectations for macroeconomic trends over the near term and loan portfolio composition differences, including expected loan lives. The impact at adoption of this standard is dependent upon the nature and characteristics of our assets in scope of the guidance, macroeconomic conditions and forecasts, as well as other management judgments.

GAAP to NON-GAAP RECONCILIATIONS

This Form 10-Q presents non-GAAP financial measures, in addition to GAAP financial measures, to provide investors with additional information. The adjustments to reconcile from the applicable GAAP financial measures to the non-GAAP financial measures are presented in the following schedules. The Bank considers these adjustments to be relevant to ongoing operating results and provide a meaningful base for period-to-period and company-to-company comparisons. These non-GAAP financial measures are used by management to assess the performance and financial position of the Bank and for presentations of Bank performance to investors. The Bank further believes that presenting these non-GAAP financial measures will permit investors to assess the performance of the Bank on the same basis as that applied by management.

Non-GAAP financial measures have inherent limitations, and are not required to be uniformly applied by individual entities. Although non-GAAP financial measures are frequently used by stakeholders to evaluate a company, they have limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of results reported under GAAP.

The following are non-GAAP financial measures presented in this Form 10-Q and a discussion of the reasons for which management uses these non-GAAP measures:

Return on Average Tangible Common Equity – this schedule also includes “net earnings applicable to common shareholders, excluding the effects of the adjustment, net of tax” and “average tangible common equity.” Return on average tangible common equity is a non-GAAP financial measure that management believes provides useful information to management and others about the Bank’s use of shareholders’ equity. Management believes the use of ratios that utilize tangible equity provides additional useful information because they present measures of those assets that can generate income.

Tangible Equity Ratio, Tangible Common Equity Ratio, and Tangible Book Value per Common Share – this schedule also includes “tangible equity,” “tangible common equity,” and “tangible assets.” Tangible equity ratio, tangible common equity ratio, and tangible book value per common share are non-GAAP financial measures that management believes provides additional useful information about the levels of tangible assets and tangible equity between each other and in relation to outstanding shares of common stock. Management believes the use of ratios that utilize tangible equity provides additional useful information to management and others about capital adequacy because they present measures of those assets that can generate income.

Efficiency Ratio and Adjusted Pre-Provision Net Revenue – this schedule also includes “adjusted noninterest expense,” “net interest margin,” “adjusted taxable-equivalent revenue,” “pre-provision net revenue (“PPNR”),” and “adjusted PPNR.” The methodology of determining the efficiency ratio may differ among companies. Management makes adjustments to exclude certain items as identified in the subsequent schedule which it believes allows for more consistent comparability among periods. Management believes the efficiency ratio provides useful information regarding the cost of generating revenue. Adjusted noninterest expense provides a measure as to how well the Bank is managing its expenses, and adjusted PPNR enables management and others to assess the Bank’s ability to generate capital to cover credit losses through a credit cycle. Net interest margin allows management to assess the comparability of revenue arising from both taxable and tax-exempt sources.

Adjusted Pre-Tax Pre-Provision Net Revenue per Share– this schedule uses “adjusted pre-provision net revenue” as calculated in the efficiency ratio, which is divided by the weighted average diluted shares for the period. As mentioned previously, Management believes that adjusted PPNR enables management and others to assess the Bank’s ability to generate capital to cover credit losses through a credit cycle. Dividing this amount by the weighted average diluted shares outstanding provides a shareholder’s perspective of PPNR growth.

RESULTS OF OPERATIONS

Executive Summary

The Bank reported net earnings applicable to common shareholders of $205 million, or $1.04 per diluted common share for the first quarter of 2019, compared with net earnings applicable to common shareholders of $231 million, or $1.09 per diluted common share for the first quarter of 2018. The financial performance in the first quarter of 2019 reflects consistent net interest income, moderate balance sheet growth, solid expense control, continued strong credit quality, and progress on key technology and process simplification initiatives, partially offset by a slight decline in customer-related fees. During the first quarter of 2019, the Bank successfully implemented the second phase of its three-phase multi-year project to replace its core loan and deposit systems. With this milestone reached, we now have substantially all our retail, commercial, and commercial real estate (“CRE”) loans on a new modern core platform.

Net income decreased by $25 million from $238 million in the first quarter of 2018 to $213 million in the first quarter of 2019 due the provision for credit losses moving from a large negative provision to a small positive provision, an $11 million increase in noninterest expense, and a $6 million decrease in noninterest income, partially offset by a $34 million increase in net interest income and a $9 million decrease in income taxes.

8

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

Net interest income increased from the first quarter of 2018 to the first quarter of 2019 primarily from loan growth and increases in short-term interest rates, partially offset by an increase in interest expense. The provision for credit losses increased from $(47) million in the first quarter of 2018, which was primarily due to oil and gas-related credit quality improvement, to $4 millionin the first quarter of 2019, reflecting loan growth and generally stable credit quality in the total loan portfolio.

When comparing the first quarter of 2019 to the first quarter of 2018, customer-related fees decreased by $3 million, or 2%, primarily due to a decrease in service charges and fees on deposit accounts. Salaries and employee benefits increased $18 million during this same time period due to increases in base salaries from annual salary merit increases and headcount, increased 401(k) plan contributions, increased employee medical expense and a decline in deferred salaries. FDIC premiums decreased by $7 million from the first quarter of 2018 to the first quarter of 2019, positively impacting net income.

Adjusted PPNR of $285 million for the first quarter of 2019 was up $20 million, or 8%, from the first quarter of 2018. The first quarter of 2018 included $11 million of interest income recoveries of at least $1 million per loan, while there were no such recoveries in the first quarter of 2019. Adjusted for these interest income recoveries, the increase in adjusted PPNR would be 12%. The increase in PPNR reflects operating leverage improvement resulting from moderate loan growth and increases in short-term interest rates, partially offset by increased interest expense and noninterest expense primarily from increased salaries and employee benefits. See “Noninterest Expense” for a more detailed discussion regarding the increased salary and employee benefits expense. The Bank’s efficiency ratio was 60.2% in the first quarter of 2019 compared with 61.3% in the first quarter of 2018 and 57.8% in the fourth quarter of 2018. The Bank is committed to further improvement of the efficiency ratio in 2019. See “GAAP to Non-GAAP Reconciliations” on page 6 for more information regarding the calculation of adjusted PPNR.

Our average loan portfolio increased $2.3 billion, or 5%, since the first quarter of 2018. We have seen widespread growth across most products and geographies, with particular strength in construction, 1-4 family residential loans, and all categories of commercial loans. Asset quality has continued to improve during the past several quarters. Credit quality in the oil and gas-related portfolio continues to strengthen and it has remained strong in the rest of the lending portfolio. Overall, from the first quarter of 2018 to the first quarter of 2019, criticized, classified, and nonaccrual loans declined by $306 million, $294 million, and $153 million, respectively.

We continue to focus on the return on- and of- capital. Return on average tangible common equity was 13.9% for the first quarter of 2019, down 160 basis points (“bps”) from the same prior year period, and our return on average assets decreased by 19 bps during the same period, primarily as a result of the negative provision in the first quarter of 2018. Regarding the return of capital, during the first quarter of 2019, the Bank repurchased 5.5 million shares of common stock for $275 million, which is equivalent to 2.9% of common stock outstanding as of December 31, 2018. Dividends per common share were $0.30 in the first quarter of 2019, compared with $0.20 for the first quarter of 2018. In April 2018, the Bank announced that its board of directors declared a regular quarterly dividend of $0.30 per common share, payable May 23, 2019 to shareholders of record on May 16, 2019. Additionally, the Board approved a plan to repurchase $275 million of common stock during the second quarter of 2019. The share repurchases have resulted in higher returns being provided to shareholders. For example, while adjusted PPNR increased 8% from the first quarter of 2018, adjusted PPNR per share increased 16% from the same prior year period. See “GAAP to Non-GAAP Reconciliations” on page 6 for more information regarding the calculation of adjusted PPNR per share. See “Capital Management” on page 30 for more information regarding the Bank’s stress testing and capital planning.

Areas of focus for 2019

In 2019, we are focused on ongoing initiatives related to Bank profitability and returns on- and of-equity. While our profitability and returns on equity in the first quarter of 2019 compared to the first quarter of 2018 have remained consistent when adjusted for the provision for credit losses and interest income recoveries, our capital distributed as a percentage of net earnings applicable to common shareholders increased to 161% from 67% for the same periods.

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

We are committed to achieve positive operating leverage and a high single-digit annual percentage growth for PPNR, and achieved an 8% growth from the first quarter of 2018 to the first quarter of 2019. We continue to implement technology upgrades and process simplification to ensure current and future performance.

We are also focused on reducing potential earnings volatility and are actively adjusting our interest rate risk profile to move towards a more neutral interest-rate sensitive position and to protect against a decline in interest rates. During the first quarter of 2019, we added approximately $3 billion of interest rate floors and $700 million of interest rate swaps. See “Interest Rate and Market Risk Management” on page 24 for further information regarding our interest rate risk management and Note 7 of the Notes to the Consolidated Financial Statements for further information regarding our use of derivative instruments. See “Areas of focus for 2019” in our 2018 Annual Report on Form 10-K for a discussion of the major areas of emphasis in 2019.

Net Interest Income

Net interest income is the difference between interest earned on interest-earning assets and interest paid on interest-bearing liabilities. Net interest income increased to $576 million in the first quarter of 2019 from $542 million in the first quarter of 2018. The $34 million, or 6%, increase in net interest income was primarily due to a $73 million increase in interest and fees on loans, resulting from increases in short-term interest rates and generally wide-spread loan growth, partially offset by an increase in interest expense.

Interest income in the first quarter of 2018 was positively impacted by $11 million of interest income recoveries of at least $1 million per loan, while there were no such recoveries in the first quarter of 2019. Adjusting for these interest income recoveries, net interest income would have increased by $45 million, or 8%.

Interest expense increased $52 million from the first quarter of 2018 to the first quarter of 2019 due to higher interest rates paid and an increase in deposits and long-term debt, partially offset by a decrease in short-term borrowings.

Net Interest Margin and Interest Rate Spreads

The net interest margin (“NIM”) was 3.68% and 3.56% for the first quarters of 2019 and 2018, respectively, and 3.67% for the fourth quarter of 2018, and reflects a higher loan yield with only a moderate increase in funding costs. Excluding the effect of the previously mentioned interest income recoveries, the NIM would have been 3.49% for the first quarter of 2018. The NIM for the first quarter of 2019, compared with the same prior year period, benefited from increases in short-term interest rates. The NIM has benefited from the stability of noninterest-bearing demand deposits in a rising interest rate environment.

Average interest-earning assets increased $1.9 billion from the first quarter of 2018 to the first quarter of 2019, with average rates improving 44 bps. Adjusting for the interest income recoveries in the first quarter of 2018, the yield on interest-earning assets would have increased 51 bps from the same prior year period. Average interest-bearing liabilities increased $2.2 billion in the first quarter of 2019 compared with the first quarter of 2018. The average rate on interest-bearing liabilities increased 54 bps from the first quarter of 2018 to the first quarter of 2019 due to rising interest rates and increased rates paid on deposits and long-term debt.

The average loan portfolio increased $2.3 billion, or 5%, between the first quarter of 2018 and the first quarter of 2019. Most of this growth was in construction, 1-4 family residential loans, and all categories of commercial loans. The average loan yield increased 42 bps over the same period, with increases in the average rates for commercial, CRE, and consumer loans of 35 bps, 64 bps, and 36 bps, respectively. Benchmark interest rates have increased several times during the last couple of years, which has had a positive impact on NIM and spreads, as our earning assets generally reprice quicker than our funding sources. A portion of our variable-rate loans were not affected by these changes primarily due to having longer reset frequencies, or because a substantial portion of our earning assets are tied to longer-term rate indices. The longer-term rates were impacted by a relatively flat yield curve during the last several quarters. Over the next four quarters, we expect moderate total loan growth.

Average AFS securities balances decreased $0.2 billion from the first quarter of 2018 to the first quarter of 2019. Yields on average AFS securities increased by 31 bps over the same period, and was primarily a result of

10

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

reinvesting principal cash flows from fixed-rate securities at higher rates and rising market interest rates on variable-rate securities.

Average noninterest-bearing demand deposits were generally stable and provided us with low cost funding and comprised approximately 43% and 45% of average total deposits for the first quarters of 2019 and 2018, respectively. Average total deposits were $53.9 billion for the first quarter of 2019 compared with $52.0 billion for the first quarter of 2018. Average interest-bearing deposits were $30.7 billion in the first quarter of 2019, compared with $28.6 billion for the same prior year period. The daily average benchmark Federal Funds target rate increased from 1.54% to 2.50% between the first quarter of 2018 and the first quarter of 2019, or 96 bps, while the rate paid on the Bank’s average interest-bearing deposits increased 47 bps, implying a deposit beta of 49%, and the rate paid on total average deposits increased 28 bps. We refer to “deposit beta” as a measure of the changes in rates paid to customers compared with changes in the average benchmark interest rates.

We have been selectively increasing deposit pricing in certain markets and with certain clients, but we have not generally experienced significant pressure to broadly increase deposit rates. Although we consider a wide variety of sources when determining our funding needs, we benefit from access to deposits from a significant number of small to mid-sized business customers, which provide us with a low cost of funds and have a positive impact on our NIM. Including wholesale borrowings, the rate paid on interest-bearing liabilities increased 54 bps. Further information regarding deposit assumptions is discussed in “Interest Rate and Market Risk Management” on page 24.

Average short-term borrowings decreased $0.4 billion compared with the same prior year period and the average interest rate paid increased by 103 bps as a result of rising short-term interest rates. Between the March 31, 2018 and March 31, 2019, we issued $1.0 billion of senior long-term debt which reduced the amount of short-term borrowing needed.

The spread on average interest-bearing funds was 3.22% and 3.32% for the first quarters of 2019 and 2018, respectively. The spread on average interest-bearing funds for these periods was affected by the same factors that had an impact on the NIM. While the spread on average interest-bearing funds decreased, the NIM still expanded as a result of the increasing value of noninterest-bearing deposits in a higher-rate environment. Because of the nature of our deposits being operating accounts for businesses and households, we expect our noninterest-bearing deposits to remain a competitive advantage. The spread on average interest-earning assets for the first quarter of 2019 decreased by 3 bps, if adjusted for the previously discussed $11 million interest recoveries recognized, or 7 bps, in the prior year period.

Interest rate spreads and margin are impacted by the mix of assets we hold, the composition of our loan and securities portfolios and the type of funding used. Additionally, as interest rates increase, our noninterest-bearing deposits become more valuable. In the first quarter of 2019 our noninterest-bearing sources of funds contributed 46 bps to the margin compared with 24 bps in the first quarter of 2018. We expect the mix of interest-earning assets to continue to change over the next four quarters primarily due to moderate-to-strong growth in 1-4 family residential, municipal, commercial and industrial, and owner-occupied loans, and stable-to-moderate growth in oil and gas and commercial real estate loans.

Our estimates of the Bank’s interest rate risk position are highly dependent upon a number of assumptions regarding the repricing behavior of various deposit and loan types in response to changes in both short-term and long-term interest rates, balance sheet composition, and other modeling assumptions, as well as the actions of competitors and customers in response to those changes. Although the federal funds target rate has increased 150 bps during the past couple of years, we have not experienced significant migration of our noninterest-bearing demand deposits which we attribute to the operating nature of many of our deposit accounts. Further detail on interest rate risk is discussed in “Interest Rate and Market Risk Management” on page 24.

The following schedule summarizes the average balances, the amount of interest earned or incurred, and the applicable yields for interest-earning assets and the costs of interest-bearing liabilities that generate taxable-equivalent net interest income.

Provision for Credit Losses

The provision for credit losses is the combination of both the provision for loan losses and the provision for unfunded lending commitments. Note 6 of our 2018 Annual Report on Form 10-K and “Credit Risk Management” on page 19 contains information on how we determine the appropriate level for the allowance for loan and lease losses (“ALLL”) and the reserve for unfunded lending commitments (“RULC”).

The provision for credit losses was $4 million in the first quarter of 2019, compared with $(47) million in the first quarter of 2018, which was primarily due to oil and gas-related credit quality improvement. The increase from the first quarter of 2018 to the first quarter of 2019 reflects loan growth and generally stable credit quality in the total loan portfolio. Classified and nonaccrual loans in the total portfolio declined by $294 million and $153 million, respectively, from the first quarter of 2018 to the first quarter of 2019. During the first quarter of 2019, there were zero net charge-offs, compared with net charge-offs of $5 million during the first quarter of 2018.

The provision for loan losses was $2 million during the first quarter of 2019, compared with $(40) million during the first quarter of 2018. This increase was primarily as a result of the previously mentioned loan growth and qualitative adjustments.

During the first quarter of 2019, we recorded a $2 million provision for unfunded lending commitments, compared with a $(7) million provision in the first quarter of 2018. This increase was primarily due to increased unfunded lending commitments and generally stable credit quality. From quarter to quarter, the provision for unfunded lending commitments may be subject to sizable fluctuations due to changes in the timing and volume of loan commitments, originations, fundings, and changes in credit quality.

The allowance for credit losses (“ACL”), which is the combination of both the ALLL and the RULC, increased $32 million, when compared with the first quarter of 2018. This was mainly due to the loan growth and increases in qualitative adjustments described previously.

Noninterest Income

Noninterest income represents revenues we earn for products and services that have no associated interest rate or yield. We believe a subtotal of customer-related fees provides a good view of income over which we have more direct control. It excludes items such as dividends, insurance-related income, mark-to-market adjustments on certain derivatives, and securities gains and losses. For the first quarter of 2019, noninterest income decreased $6 million, or 4%, compared with the first quarter of 2018, primarily due to a $3 million decrease in customer-related fees, a $2 million decrease in dividends and other investment income, and a $2 million decrease in other noninterest income. The following schedule presents a comparison of the major components of noninterest income.

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

Customer-related fees decreased $3 million, or 2% from the first quarter of 2018 to the first quarter of 2019 primarily from a $2 million decrease in service charges and fees on deposit accounts. The decrease in service charges and fees on deposit accounts was largely attributable to an unfavorable impact from the earnings credit rate associated with noninterest-bearing demand deposits and softness in retail and small business service charges.

Dividends and other investment income decreased by $2 million primarily as a result of increases in the market values of the Company’s Small Business Investment Company (“SBIC”) investments in the first quarter of 2018 that did not reoccur in the first quarter of 2019. Other noninterest income decreased $2 million primarily due to a decrease in credit valuation adjustments on client-related derivatives, partially offset by a gain on the sale of a minor product line.

Noninterest Expense

Noninterest expense increased by $11 million, or 3%, from the first quarter of 2018 to the first quarter of 2019. As discussed subsequently, adjusted noninterest expense also increased 3% over the same period. The Bank remains focused on expense control efforts, while continuing to invest in technology and process simplification initiatives. As previously mentioned, during the first quarter of 2019, the Bank successfully implemented the second phase of its three-phase multi-year project to replace its core loan and deposit systems, upgrading its commercial loans core system. The Bank continues to work on upgrading its primary deposit system. This 3% increase is within our targeted growth rate of low single-digit percentage range relative to the prior year.

The following schedule presents a comparison of the major components of noninterest expense.

Salary and employee benefits expense was up $18 million in the first quarter of 2019, compared with the first quarter of 2018. In the first quarter of 2019, we increased some key benefits to employees which are designed to appropriately reward our employees for significantly improved financial performance. The increase in salaries and employee benefits was primarily due to a $6 million increase in base salaries resulting from annual salary merit increases and employee headcount, a $3 million increase in the Bank’s contribution to the employee 401(k) plan as a result of an increased matching contribution and higher profit sharing, and a $2 million increase in incentive compensation. The remaining $7 million increase was primarily a result of an increase in share-based compensation and employee medical expenses, and a decline in deferred salaries.

These increases in noninterest expense were partially offset by a $7 million decrease in FDIC premiums due to the elimination of the FDIC surcharge for large banks because the required Deposit Insurance Fund reserve ratio has been met.

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

Adjusted noninterest expense for the first quarter of 2019 increased $12 million, or 3%, to $431 million, compared with $419 million for the same prior year period. To arrive at adjusted noninterest expense, GAAP noninterest expense is adjusted to exclude certain expense items, which are the same as those items excluded in arriving at the efficiency ratio (see “GAAP to Non-GAAP Reconciliations” on page 6 for more information regarding the calculation of the efficiency ratio). We expect adjusted noninterest expense for 2019 to experience an increase in the low single-digit percentage range relative to the prior year.

Income Taxes

Income tax expense for the first quarter of 2019 was $61 million compared with $70 million for the same prior year period. The effective income tax rates were 22.3% and 22.7% for the first quarters of 2019 and 2018, respectively. Note 13 of the Notes to Consolidated Financial Statements contains additional information about the factors that influenced the income tax rates and information about deferred income tax assets and liabilities. The effective tax rate for 2019 is expected to be approximately 23%, including the effects of stock-based compensation.

Preferred Stock Dividends

Preferred stock dividends have been consistent over the past year and were $8 million and $7 million during the first quarters of 2019 and 2018, respectively.

BALANCE SHEET ANALYSIS

Interest-Earning Assets

Interest-earning assets are those assets that have interest rates or yields associated with them. One of our goals is to maintain a high level of interest-earning assets relative to total assets while keeping nonearning assets at a minimum. Interest-earning assets consist of money market investments, securities, loans, and leases.

Another goal is to maintain a higher-yielding mix of interest-earning assets, such as loans, relative to lower-yielding assets, while maintaining adequate levels of highly liquid assets. As a result of this goal we redeployed funds from lower-yielding money market investments, in addition to using wholesale borrowings, to purchase agency securities.

For information regarding the average balances of our interest-earning assets, the amount of revenue generated by them, and their respective yields, see the average balance sheet on page 12.

Average interest-earning assets were $64.2 billion for the first three months of 2019, compared with $62.2 billion for the first three months of 2018. Average interest-earning assets as a percentage of total average assets were 94% for both the first three months of 2019 and 2018.

Average loans were $47.2 billion and $44.9 billion for the first three months of 2019 and 2018, respectively. Average loans as a percentage of total average assets for the first three months of 2019 were 69%, compared with 68% in the same prior year period.

Average money market investments, consisting of interest-bearing deposits, federal funds sold, and security resell agreements, decreased by 15% to $1.3 billion for the first three months of 2019, compared with $1.5 billion for the first three months of 2018. Average securities decreased by 1% for the first three months of 2019, compared with the first three months of 2018.

Investment Securities Portfolio

We invest in securities to actively manage liquidity and interest rate risk, in addition to generating revenue for the Bank. Refer to the “Liquidity Risk Management” section on page 28 for additional information on management of liquidity and funding. The following schedule presents a profile of our investment securities portfolio. The amortized cost amounts represent the original cost of the investments, adjusted for related accumulated amortization or accretion of any yield adjustments, and for impairment losses, including credit-related impairment. The estimated fair value measurement levels and methodology are discussed in Note 3of our 2018 Annual Report on Form 10-K.

The investment securities portfolio includes $411 million of net premium that is distributed across various asset classes as illustrated in the preceding schedule. Premium amortization for the three months ended March 31, 2019, was approximately $31 million, compared with approximately $33 million for the same period in 2018, reducing the yield on securities by 86 bps compared with a 89 bps impact for the same period in 2018.

As of March 31, 2019, under the GAAP fair value accounting hierarchy, 0.3% of the $14.9 billion fair value of the AFS securities portfolio was valued at Level 1, 99.7% was valued at Level 2, and there were no Level 3 AFS securities. At December 31, 2018, 0.3% of the $14.7 billion fair value of AFS securities portfolio was valued at Level 1, 99.7% was valued at Level 2, and there were no Level 3 AFS securities. See Note 3 of our 2018 Annual Report on Form 10-K for further discussion of fair value accounting.

Exposure to State and Local Governments

We provide multiple products and services to state and local governments (referred to collectively as “municipalities”), including deposit services, loans, and investment banking services, and we invest in securities issued by the municipalities.

Loan portfolio growth during the first three months of 2019 was widespread across loan products and geographies with particular strength intotal commercial real estate, commercial and industrial, consumer 1-4 family residential, and municipal loans. The growth in the loan portfolio was primarily at Amegy Bank (“Amegy”) and National Bank of Arizona (“NBAZ”).

Other Noninterest-Bearing Investments

During the first three months of 2019, the Bank decreased its short-term borrowings with the Federal Home Loan Bank (“FHLB”) by $1.25 billion. This decrease also led to a decline in FHLB activity stock, which consequently decreased by $50 million during the year. Aside from this decrease, other noninterest-bearing investments remained relatively stable as set forth in the following schedule.

Premises, Equipment, and Software

Net premises, equipment, and software increased $1 million, or 0.1%, during the first three months of 2019. In 2017, the Bank implemented the first phase of our core lending and deposit systems replacement project, which replaced the Bank’s primary consumer lending systems. During the first quarter of 2019, the Bank successfully implemented the second phase of this project by replacing its primary commercial and commercial real estate lending systems. With this milestone reached, we now have substantially all our retail, commercial and commercial real estate loans on a new modern core platform. The Bank is well underway with the project to convert its deposit servicing system by 2022. The total core replacement project spend amount is comprised of both capitalized amounts and amounts that are expensed as incurred. The useful life for most of the capitalized costs is 10 years. The following schedule shows the total amount of costs capitalized, less accumulated depreciation, by phase for the core replacement project.

Deposits

Deposits, both interest-bearing and noninterest-bearing, are a primary source of funding for the Bank. Average total deposits for the first three months of 2019 increased by 4%, compared with the first three months of 2018, with average interest-bearing deposits increasing by 7% and average noninterest-bearing deposits decreasing by 1%. The average interest rate paid for interest-bearing deposits was 47 bps higher during the first three months of 2019, compared with the first three months of 2018.

Demand, savings, and money market deposits were 91% and 92% of total deposits at March 31, 2019 and December 31, 2018, respectively. At March 31, 2019 and December 31, 2018, total deposits included $2.6 billion and $2.2 billion, respectively, of brokered deposits.

See “Liquidity Risk Management” on page 28 for additional information on funding and borrowed funds.

RISK ELEMENTS

Since risk is inherent in substantially all of the Bank’s operations, management of risk is an integral part of its operations and is also a key determinant of its overall performance. The Board of Directors has appointed a Risk Oversight Committee (“ROC”) that consists of appointed Board members who oversee the Bank’s risk management processes. The ROC meets on a regular basis to monitor and review Enterprise Risk Management (“ERM”) activities. As required by its charter, the ROC performs oversight for various ERM activities and approves ERM policies and activities as detailed in the ROC charter.

Management applies various strategies to reduce the risks to which the Bank’s operations are exposed, including credit, interest rate and market, liquidity, and operational risks. These risks are overseen by the various management

18

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

committees of which the Enterprise Risk Management Committee is the focal point for the monitoring and review of enterprise risk.

Credit Risk Management

Credit risk is the possibility of loss from the failure of a borrower, guarantor, or another obligor to fully perform under the terms of a credit-related contract. Credit risk arises primarily from our lending activities, as well as from off-balance sheet credit instruments. For a more comprehensive discussion of credit risk management, see “Credit Risk Management” in our 2018 Annual Report on Form 10-K.

Government Agency Guaranteed Loans

We participate in various guaranteed lending programs sponsored by U.S. government agencies, such as the Small Business Administration (“SBA”), Federal Housing Authority, Veterans’ Administration, Export-Import Bank of the U.S., and the U.S. Department of Agriculture. As of March 31, 2019, the principal balance of these loans was $564 million, and the guaranteed portion of these loans was $427 million. Most of these loans were guaranteed by the SBA. The following schedule presents the composition of government agency guaranteed loans.

¹  No other geography exceeds $96 million for all three loan types.

²  Delinquency rates include nonaccrual loans.

Approximately 11% of the CRE term loans consist of mini-perm loans as of March 31, 2019. For such loans, construction has been completed and the project has stabilized to a level that supports the granting of a mini-perm loan in accordance with our underwriting standards. Mini-perm loans generally have initial maturities of three to

20

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

five years. The remaining 89% of CRE loans are term loans with initial maturities generally of 5 to 20 years. The stabilization criteria for a project to qualify for a term loan differ by product type and include criteria related to the cash flow generated by the project, loan-to-value ratio, and occupancy rates.

Approximately $231 million, or 10%, of the commercial construction and land development portfolio at March 31, 2019 consists of land acquisition and development loans. Most of these land acquisition and development loans are secured by specific retail, apartment, office, or other projects.

For a more comprehensive discussion of commercial real estate loans, see the “Commercial Real Estate Loans” section in our 2018 Annual Report on Form 10-K.

Consumer Loans

We have mainly been an originator of first and second mortgages, generally considered to be of prime quality. We generally hold variable-rate loans in our portfolio and sell “conforming” fixed-rate loans to third parties, including Federal National Mortgage Association and Federal Home Loan Mortgage Corporation, for which we make representations and warranties that the loans meet certain underwriting and collateral documentation standards.

We are also engaged in Home Equity Credit Line (“HECL”) lending. At both March 31, 2019 and December 31, 2018, our HECL portfolio totaled $2.9 billion. The following schedule describes the composition of our HECL portfolio by lien status.

HECL PORTFOLIO BY LIEN STATUS

(In millions)	March 31, 2019		December 31, 2018
Secured by first deeds of trust	$	1,410	$	1,458
Secured by second (or junior) liens	1,474		1,479
Total	$	2,884	$	2,937

At March 31, 2019, loans representing less than 1% of the outstanding balance in the HECL portfolio were estimated to have combined loan-to-value ratios (“CLTV”) above 100%. An estimated CLTV ratio is the ratio of our loan plus any prior lien amounts divided by the estimated current collateral value. At origination, underwriting standards for the HECL portfolio generally include a maximum 80% CLTV with high credit scores at origination.

Approximately 89% of our HECL portfolio is still in the draw period, and approximately 15% of those loans are scheduled to begin amortizing within the next five years. We regularly analyze the risk of borrower default in the event of a loan becoming fully amortizing and the risk of higher interest rates. The analysis indicates that the risk of loss from this factor is minimal in the current economic environment. The annualized ratio of net charge-offs to average balances for the first three months of 2019 and 2018 for the HECL portfolio was (0.09)% and 0.06%, respectively. See Note 6 of the Notes to Consolidated Financial Statements for additional information on the credit quality of this portfolio.

Nonperforming Assets

Nonperforming assets as a percentage of loans and leases and other real estate owned (“OREO”) decreased to 0.50% at March 31, 2019, compared with 0.55% at December 31, 2018.

Total nonaccrual loans at March 31, 2019 decreased $18 million from December 31, 2018, primarily in the commercial and industrial loan portfolio. The largest total decrease in nonaccrual loans occurred at Amegy, mainly due to improvements in the oil and gas-related portfolio.

The balance of nonaccrual loans can decrease due to paydowns, charge-offs, and the return of loans to accrual status under certain conditions. If a nonaccrual loan is refinanced or restructured, the new note is immediately placed on nonaccrual. If a restructured loan performs under the new terms for at least a period of six months, the loan can be considered for return to accrual status. See “Restructured Loans” following for more information. Bank policy does

21

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

not allow for the conversion of nonaccrual construction and land development loans to CRE term loans. See Note 6 of the Notes to Consolidated Financial Statements for more information on nonaccrual loans.

The following schedule sets forth our nonperforming assets:

Nonaccrual loans1 current as to principal and interest payments	58.9		%	58.5		%

¹ Includes loans held for sale.

Restructured Loans

Troubled debt restructurings (“TDRs”) are loans that have been modified to accommodate a borrower who is experiencing financial difficulties, and for whom we have granted a concession that we would not otherwise consider. TDRs decreased $28 million, or 14%, during the first three months of 2019, primarily due to payments and payoffs. Commercial loans may be modified to provide the borrower more time to complete the project, to achieve a higher lease-up percentage, to sell the property, or for other reasons. Consumer loan TDRs represent loan modifications in which a concession has been granted to the borrower who is unable to refinance the loan with another lender, or who is experiencing economic hardship. Such consumer loan TDRs may include first-lien residential mortgage loans and home equity loans.

If the restructured loan performs for at least six months according to the modified terms, and an analysis of the customer’s financial condition indicates that we are reasonably assured of repayment of the modified principal and interest, the loan may be returned to accrual status. The borrower’s payment performance prior to and following the restructuring is taken into account to determine whether a loan should be returned to accrual status.

Allowance for Credit Losses

In analyzing the adequacy of the ALLL, we utilize a comprehensive loan grading system to determine the risk potential in the portfolio and also consider the results of independent internal credit reviews. To determine the adequacy of the allowance, our loan and lease portfolio is broken into segments based on loan type.

The following schedule shows the changes in the allowance for loan losses and a summary of loan loss experience:

See Note 6 of the Notes to Consolidated Financial Statements for additional information related to the ACL and credit trends experienced in each portfolio segment.

Interest Rate and Market Risk Management

Interest rate and market risk are managed centrally. Interest rate risk is the potential for reduced net interest income and other rate sensitive income resulting from adverse changes in the level of interest rates. Market risk is the potential for loss arising from adverse changes in the fair value of fixed income securities, equity securities, other earning assets, and derivative financial instruments as a result of changes in interest rates or other factors. As a financial institution that engages in transactions involving an array of financial products, we are exposed to both interest rate risk and market risk.

The Bank’s Board of Directors is responsible for approving the overall policies relating to the management of the financial risk of the Bank, including interest rate and market risk management. The Board has established the Asset/Liability Committee (“ALCO”) consisting of members of management, to which it has delegated the responsibility of managing interest rate and market risk for the Bank. ALCO establishes and periodically revises policy limits and reviews with the ROC the limits and limit exceptions reported by management.

Interest Rate Risk

Interest rate risk is one of the most significant risks to which we are regularly exposed. In general, our goal in managing interest rate risk is to manage balance sheet sensitivity to reduce net income volatility due to changes in interest rates.

Over the course of the last several years, we have actively reduced the level of asset-sensitivity through the purchase of short-to-medium duration agency pass-through securities and funding these purchases by reducing money market investments and increasing short-term borrowings. This repositioning of the investment portfolio has increased current net interest income while dampening the impact of higher rates on net interest income growth. We continue to anticipate moderately higher net interest income in a rising rate environment as our assets reprice more quickly than our liabilities.

Interest Rate Risk Measurement

We monitor interest rate risk through the use of two complementary measurement methods: net interest income simulation, or Earnings at Risk (“EaR”), and Economic Value of Equity at Risk (“EVE”). EaR analyzes the expected change in near term (one year) net interest income in response to changes in interest rates. In the EVE method, we measure the expected changes in the fair value of equity in response to changes in interest rates.

EaR is an estimate of the change in total net interest income that would be recognized under different rate environments over a one-year period. EaR is measured simulating net interest income under several different scenarios including parallel and nonparallel interest rate shifts across the yield curve, taking into account deposit repricing assumptions and estimates of the possible exercise of embedded options within the portfolio (e.g., a borrower’s ability to refinance a loan under a lower-rate environment). Our policy contains a trigger for a 10% decline in rate sensitive income as well as a risk capacity of a 13% decline if rates were to immediately rise or fall in parallel by 200 bps. As of December 31, 2018 the EaR declined by 12% for a 200 bps decline in rates. This trigger violation informed our decision to move to a less asset-sensitive position throughout 2019.

EVE is calculated as the fair value of all assets minus the fair value of liabilities. We measure changes in the dollar amount of EVE for parallel shifts in interest rates. Due to embedded optionality and asymmetric rate risk, changes in EVE can be useful in quantifying risks not apparent for small rate changes. Examples of such risks may include out-of-the-money interest rate caps (or limits) on loans, which have little effect under small rate movements but may become important if large rate changes were to occur, or substantial prepayment deceleration for low-rate mortgages in a higher-rate environment. Our policy contains a trigger for an 8% decline in EVE as well as a risk capacity of a

24

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

10% decline if rates were to immediately rise or fall in parallel by 200 bps. Exceptions to the EVE limits are subject to notification and approval by the ROC.

Estimating the impact on net interest income and EVE requires that we assess a number of variables and make various assumptions in managing our exposure to changes in interest rates. The assessments address deposit withdrawals and deposit product migration (e.g., customers moving money from checking accounts to certificates of deposit), competitive pricing (e.g., existing loans and deposits are assumed to roll into new loans and deposits at similar spreads relative to benchmark interest rates), loan and security prepayments, and the effects of other similar embedded options. As a result of uncertainty about the maturity and repricing characteristics of both deposits and loans, we also calculate the sensitivity of EaR and EVE results to key assumptions. As most of our liabilities are comprised of indeterminate maturity and managed rate deposits, the modeled results are highly sensitive to the assumptions used for these deposits, such as checking, savings and money market accounts, and also to prepayment assumptions used for loans with prepayment options. We use historical regression analysis as a guide for setting such assumptions; however, due to the current low interest rate environment, which has little historical precedent, estimated deposit behavior may not reflect actual future results. Additionally, competition for funding in the marketplace has and may again result in changes to deposit pricing on interest-bearing accounts that are greater or less than changes in benchmark interest rates such as the London Interbank Offered Rate (“LIBOR”) or the federal funds rate.

Under most rising interest rate environments, we would expect some customers to move balances from demand deposits to interest-bearing accounts such as money market, savings, or certificates of deposit. The models are particularly sensitive to the assumption about the rate of such migration.

In addition, we assume certain correlation rates, often referred to as a “deposit beta,” of interest-bearing deposits, wherein the rates paid to customers change at a different pace when compared with changes in average benchmark interest rates. Generally, certificates of deposit are assumed to have a high correlation rate, while interest-on-checking accounts are assumed to have a lower correlation rate. Actual results may differ materially due to factors including competitive pricing, money supply, credit worthiness of the Bank, and so forth; however, we use our historical experience as well as industry data to inform our assumptions.

The aforementioned migration and correlation assumptions result in deposit durations presented in the following schedule.

DEPOSIT ASSUMPTIONS

	March 31, 2019
Product	Effective duration (unchanged)		Effective duration (+200 bps)
Demand deposits	3.2	%	2.9	%
Money market	3.0	%	1.1	%
Savings and interest-on-checking	3.0	%	2.4	%

As of the dates indicated and incorporating the assumptions previously described, the following schedule shows EaR, or percentage change in net interest income, based on a static balance sheet size, in the first year after the interest rate change if interest rates were to sustain immediate parallel changes ranging from -100 bps to +300 bps.

For non-maturity interest-bearing deposits, the weighted average modeled beta is 45%. If the weighted average deposit beta increased to 55% it would decrease the EaR in the +200bps shock from 5.3% to 2.6%.

The EaR analysis focuses on parallel rate shocks across the term structure of rates. The yield curve typically does not move in a parallel manner. During the past year, an increase in short-term rates has led to a flatter yield curve as longer-term rates have not increased at the same pace as short-term rates. If we consider a flattening rate shock where the short-term rate moves +200bps but the ten-year rate only moves +30bps, the increase in earnings is 33% lower over 12 months compared with the parallel +200bps rate shock.

For comparative purposes, the December 31, 2018 measures are presented in the following schedule.

	December 31, 2018
	Parallel shift in rates (in bps)1
Repricing scenario	-100		0		+100		+200		+300

¹  Assumes rates cannot go below zero in the negative rate shift.

The asset-sensitivity as measured by EaR decreased slightly quarter-over-quarter due to changes in the investment securities and funding compositions.

CHANGES IN ECONOMIC VALUE OF EQUITY

As of the dates indicated, the following schedule shows our estimated percentage change in EVE under parallel interest rate changes ranging from -100 bps to +300 bps. For non-maturity interest-bearing deposits, the weighted average modeled beta is 45%. If the weighted average deposit beta increased to 55% it would decrease the EVE in the +200bps shock from (2.4)% to (5.4)%.

	March 31, 2019
	Parallel shift in rates (in bps)1
Repricing scenario	-100		0		+100		+200		+300
Economic Value of Equity	3.1	%	—	%	(0.2	)%	(2.4	)%	(4.8	)%

¹  Assumes rates cannot go below zero in the negative rate shift.

For comparative purposes, the December 31, 2018 measures are presented in the following schedule. The changes in EVE measures from December 31, 2018 are driven by increases in interest rates which increase the expected life of certain assets and decrease the expected life of certain liabilities.

	December 31, 2018
	Parallel shift in rates (in bps)1
Repricing scenario	-100 bps		0 bps		+100 bps		+200 bps		+300 bps
Economic Value of Equity	(2.5	)%	—	%	(2.1	)%	(5.6	)%	(5.4	)%

¹  Assumes rates cannot go below zero in the negative rate shift.

Our focus on business banking also plays a significant role in determining the nature of the Bank’s asset-liability management posture. At March 31, 2019, $21 billion of the Bank’s commercial lending and CRE loan balances were scheduled to reprice in the next six months. Of these variable-rate loans approximately 98% are tied to either the prime rate or LIBOR. For these variable-rate loans we have executed $4.3 billion of cash flow hedges by receiving fixed rates on interest rate swaps or through purchased interest rate floors. Additionally, asset-sensitivity is reduced due to $66 million of variable-rate loans being priced at floored rates at March 31, 2019, which were above the “index plus spread” rate by an average of 62 bps. At March 31, 2019, we also had $3.4 billion of variable-rate consumer loans scheduled to reprice in the next six months. Of these variable-rate consumer loans approximately $9 million were priced at floored rates, which were above the “index plus spread” rate by an average of 79 bps.

See Notes 3 and 7 of the Notes to Consolidated Financial Statements for additional information regarding derivative instruments.

In July 2017, the Financial Conduct Authority, the authority regulating LIBOR, along with various other regulatory bodies, announced that LIBOR would likely be discontinued at the end of 2021. LIBOR makes up the most liquid and common interest rate index in the world and is commonly referenced in financial instruments. We have exposure to LIBOR in various aspects through its financial contracts. We are currently working with various industry groups and internal working groups to determine an appropriate replacement index for affected contracts that expire after the expected discontinuation of LIBOR on December 31, 2021. Instruments that may be impacted include loans, securities, and derivatives, among other financial contracts indexed to LIBOR and that mature after December 31, 2021. We are actively working to address any impacted contracts but realize that amending certain contracts indexed to LIBOR may require consent from the counterparties which could be difficult and costly to obtain in certain limited circumstances.

Market Risk – Fixed Income

We engage in the underwriting and trading of municipal securities. This trading activity exposes us to a risk of loss arising from adverse changes in the prices of these fixed income securities.

At March 31, 2019, we had a relatively small amount, $316 million, of trading assets and $52 million of securities sold, not yet purchased, compared with $106 million and $85 million, respectively, at December 31, 2018.

We are exposed to market risk through changes in fair value. We are also exposed to market risk for interest rate swaps used to hedge interest rate risk. Changes in the fair value of AFS securities and in interest rate swaps that qualify as cash flow hedges are included in accumulated other comprehensive income (“AOCI”) for each financial reporting period. During the first quarter of 2019, the after-tax change in AOCI attributable to AFS securities increased by $121 million, due largely to changes in the interest rate environment, compared with a $126 million decrease in the same prior year period.

Market Risk – Equity Investments

Through our equity investment activities, we own equity securities that are publicly-traded. In addition, we own equity securities in companies and governmental entities, e.g., the Federal Reserve Bank and an FHLB, that are not publicly-traded. The accounting for equity investments may use the cost, fair value, equity, or full consolidation methods of accounting, depending on our ownership position and degree of involvement in influencing the investees’ affairs. Regardless of the accounting method, the value of our investment is subject to fluctuation. Because the fair value of these securities may fall below our investment costs, we are exposed to the possibility of loss. Equity investments in private and public companies are approved, monitored and evaluated by the Bank’s Equity Investment Committee consisting of members of management.

We hold both direct and indirect investments in predominantly pre-public companies, primarily through various SBIC venture capital funds. Our equity exposure to these investments was approximately $139 million and $132 million at March 31, 2019 and December 31, 2018, respectively. On occasion, some of the companies within our SBIC investments may issue an initial public offering. In this case, the fund is generally subject to a lockout period before liquidating the investment, which can introduce additional market risk.

Additionally, Amegy has an alternative investments portfolio. These investments are primarily directed towards equity buyout and mezzanine funds with a key strategy of deriving ancillary commercial banking business from the portfolio companies. Early-stage venture capital funds are generally not a part of the strategy because the underlying companies are typically not creditworthy. The carrying value of Amegy’s equity investments was $11 million at both March 31, 2019 and December 31, 2018.

Liquidity Risk Management

Overview

Liquidity refers to our capacity to meet our cash and collateral obligations and to manage both expected and unexpected cash flows without adversely impacting the operations or financial strength of the Bank. Sources of liquidity include both traditional forms of funding, such as deposits, borrowings, and equity and unencumbered assets, such as marketable loans and securities. The Bank continues to perform liquidity stress tests and assess its portfolio of highly liquid assets (sufficient to cover 30-day funding needs under the stress scenarios). At March 31, 2019, our investment securities portfolio of $16.0 billion and cash and money market investments of $1.7 billion collectively comprised 26% of total assets.

Liquidity Management Actions

The Bank’s consolidated cash, interest-bearing deposits held as investments, and security resell agreements decreased to $1.6 billion at March 31, 2019 from $2.4 billion at December 31, 2018. During the first quarter of 2019 uses of cash were primarily from (1) loan originations, (2) repayment of short-term borrowings, (3) repurchases of our common stock, and (4) dividends on common and preferred stock. The primary sources of cash during the same period were from (1) the issuance of long-term debt, (2) a net increase in deposits, and (3) a decrease in federal funds sold.

The Bank’s loan to total deposit ratio has remained consistent and was 87% at March 31, 2019 compared with 86% at December 31, 2018, indicating a slightly higher loan growth than deposit growth. The Bank’s core deposits, consisting of noninterest-bearing demand deposits, savings and money market deposits, and time deposits under $250,000, was $51.1 billion at March 31, 2019 compared with $51.2 billion at December 31, 2018.

Total deposits increased to $54.5 billion at March 31, 2019, from $54.1 billion at December 31, 2018. The increase for the first quarter of 2019 was a result of a $592 million and $228 million increase in time deposits and savings and money market deposits, respectively, partially offset by a $386 million decrease in noninterest-bearing demand deposits.

During the first quarter of 2019, the Bank issued a $500 million senior note with an interest rate of 3.35% and a maturity date of March 4, 2022. At March 31, 2019, maturities of our long-term senior and subordinated debt ranged from August 2021 to September 2028.

The Bank’s cash payments for interest, reflected in operating expenses, increased to $95 million during the first quarter of 2019 from $44 million during the first quarter of 2018 primarily due to an increase in deposits, long-term debt, and interest rates. Additionally, the Bank paid approximately $66 million of dividends on preferred stock and common stock for the first quarter of 2019 compared with $49 million for the first quarter of 2018. Dividends paid per common share increased from $0.20 in the first quarter of 2018 to $0.30 in the first quarter of 2019. In April 2019, the Board approved a quarterly common dividend of $0.30 per share.

General financial market and economic conditions impact our access to, and cost of, external financing. Access to funding markets for the Bank is also directly affected by the credit ratings received from various rating agencies. The ratings not only influence the costs associated with the borrowings, but can also influence the sources of the borrowings. All of the credit rating agencies rate the Bank’s debt at an investment-grade level. The Bank’s credit ratings did not change during the first quarter of 2019 and are presented in the following schedule.

CREDIT RATINGS
as of April 30, 2019:
Rating agency	Outlook	Long-term issuer/senior debt rating	Subordinated debt rating	Short-term debt rating

The FHLB system and Federal Reserve Banks have been and are a source of back-up liquidity and a significant source of funding. Zions Bancorporation, N.A. is a member of the FHLB of Des Moines. The FHLB allows member banks to borrow against their eligible loans and securities to satisfy liquidity and funding requirements. The Bank is required to invest in FHLB and Federal Reserve stock to maintain their borrowing capacity.

At March 31, 2019, the amount available for additional FHLB and Federal Reserve borrowings was approximately $15.7 billion, compared with $13.8 billion at December 31, 2018. Loans with a carrying value of approximately $23.4 billion at March 31, 2019 have been pledged at the FHLB of Des Moines and the Federal Reserve as collateral for current and potential borrowings compared with $22.6 billion at December 31, 2018. At March 31, 2019, we had $3.3 billion of short-term FHLB borrowings outstanding and no long-term FHLB or Federal Reserve borrowings outstanding, compared with $4.5 billion of short-term FHLB borrowings and no long-term FHLB or Federal Reserve borrowings outstanding at December 31, 2018. At March 31, 2019, our total investment in FHLB and Federal Reserve stock was $140 million and $131 million, respectively, compared with $190 million and $139 million at December 31, 2018.

Our investment activities can provide or use cash, depending on the asset-liability management posture taken. During the first quarter of 2019, HTM and AFS investment securities’ activities resulted in a net increase in investment securities and a net $26 million decrease in cash, compared with a net $59 million increase in cash for the first quarter of 2018.

Maturing balances in the Bank’s loan portfolios also provide additional flexibility in managing cash flows. Lending activity for the first quarter of 2019 resulted in a net cash outflow of $860 million compared with a net cash outflow of $311 million for the first quarter of 2018.

We may also, from time to time, issue additional preferred stock, senior or subordinated notes or other forms of capital or debt instruments, depending on our capital, funding, asset-liability management or other needs as market conditions warrant and subject to any required regulatory approvals. Management believes that the sources of available liquidity are adequate to meet all reasonably foreseeable short-term and intermediate-term demands. A more comprehensive discussion of liquidity risk management, including certain contractual obligations, is contained in our 2018 Annual Report on Form 10-K.

Operational Risk Management

Operational risk is the risk to current or anticipated earnings or capital arising from inadequate or failed internal processes or systems, human errors or misconduct, or adverse external events. In our ongoing efforts to identify and manage operational risk, we have an ERM department whose responsibility is to help employees, management and the Board of Directors to assess, understand, measure, manage, and monitor risk in accordance with our Risk Appetite Framework. We have documented both controls and the Control Self-Assessment related to financial reporting under the 2013 framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”).

Periodic reviews by the Bank’s Compliance Risk Management, Internal Audit and Credit Examination departments are conducted on a regular basis, and the Data Governance department also provides key governance surrounding data integrity and availability oversight. We are continually improving our oversight of operational risk, including enhancement of risk identification, risk and control self-assessments, and antifraud measures, which are reported on a regular basis to enterprise management committees.

The number and sophistication of attempts to disrupt or penetrate our critical systems, sometimes referred to as hacking, cyber fraud, cyber attacks, cyber terrorism, or other similar names, also continue to grow. Given the importance and increasing sophistication of cyber attacks, the Bank has designated cyber risk a level one risk in its risk taxonomy, which places it at the highest level of oversight with its other top risks.

For a more comprehensive discussion of operational risk management see our 2018 Annual Report on Form 10-K.

CAPITAL MANAGEMENT

Overview

We believe that a strong capital position is vital to continued profitability and to promoting depositor and investor confidence. The bank has a fundamental financial objective to consistently produce superior risk-adjusted returns on its shareholders’ capital. The Bank continues to utilize stress testing as the primary mechanism to inform its decisions on the appropriate level of capital and capital actions, based upon actual and hypothetically-stressed economic conditions. The timing and amount of capital actions are subject to various factors, including the Bank's financial performance, business needs, prevailing and anticipated economic conditions, and OCC approval.

Capital Management Actions

During the first quarter of 2019, the Bank repurchased 5.5 million shares of common stock, or 2.9% of common stock outstanding as of December 31, 2018, for $275 million at an average price of $50.03 per share. During the last four quarters, the Bank repurchased 16.3 million shares of common stock, or 8.3% of common stock outstanding as of March 31, 2018, for $830 million at an average price of $50.96 per share. In April 2019, the Bank announced that the Board of Directors approved a plan to repurchase $275 million of common stock during the second quarter of 2019. Shares may be repurchased occasionally in the open market, through privately negotiated transactions, utilizing Rule 10b5-1 plans or otherwise.

The Bank paid common dividends of $56 million, or $0.30 per share, during the first quarter of 2019 compared to $39 million, or $0.20 per share, during the first quarter of 2018. In April 2019, the Board of Directors declared a quarterly dividend of $0.30 per common share payable on May 23, 2019 to shareholders of record on May 16, 2019. The Bank also paid dividends on preferred stock of $10 million for both the first quarters of 2019 and 2018. See Note 9 for additional detail about capital management transactions during the first quarter of 2019.

Total shareholders’ equity has remained consistent and was $7.6 billion at both March 31, 2019 and March 31, 2018. The primary increases in shareholders’ equity during the first quarter of 2019 was net income of $213 million and $128 million from an increase in the fair value of our AFS securities due largely to changes in the interest rate environment. The primary decreases during the same time period was $275 million from repurchases of Bank common stock and $66 million from common and preferred stock dividends paid.

Weighted average diluted shares decreased by 15 million compared with the first quarter of 2018, primarily due to Bank share repurchases and a decrease in the Bank’s common share price which reduced the dilutive impact of warrants outstanding. As of March 31, 2019, the Bank had 29.3 million ZIONW warrants outstanding with an exercise price of $34.61 which expire on May 22, 2020.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

March 31, 2019

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of Zions Bancorporation, National Association and its majority-owned subsidiaries (collectively “Zions Bancorporation, N.A.,” “the Bank,” “we,” “our,” “us”) have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. References to GAAP, including standards promulgated by the Financial Accounting Standards Board (“FASB”), are made according to sections of the Accounting Standards Codification (“ASC”). Changes to the ASC are made with Accounting Standards Updates (“ASU”) that include consensus issues of the Emerging Issues Task Force.

Operating results for the three months endedMarch 31, 2019 and 2018 are not necessarily indicative of the results that may be expected in future periods. In preparing the consolidated financial statements, we are required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The consolidated balance sheet at December 31, 2018 is from the audited financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Bank’s 2018 Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform with the current period presentation. These reclassifications did not affect net income or shareholders’ equity.

Zions Bancorporation, N.A. is a commercial bank headquartered in Salt Lake City, Utah. The Bank provides a full range of banking and related services in 11 Western and Southwestern states through 7 separately managed and branded units as follows: Zions Bank, in Utah, Idaho and Wyoming; Amegy Bank (“Amegy”), in Texas; California Bank & Trust (“CB&T”); National Bank of Arizona (“NBAZ”); Nevada State Bank (“NSB”); Vectra Bank Colorado (“Vectra”), in Colorado and New Mexico; and The Commerce Bank of Washington (“TCBW”) which operates under that name in Washington and under the name The Commerce Bank of Oregon in Oregon.

2. RECENT ACCOUNTING PRONOUNCEMENTS AND DEVELOPMENTS

Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
Standards not yet adopted by the Bank
ASU 2016-13, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This ASU significantly changes how entities will measure credit losses for virtually all financial assets and certain other instruments that are not measured at fair value through net income that have the contractual right to receive cash. The standard replaces today’s “incurred loss” approach with an “expected loss” model for instruments such as loans and held-to-maturity (“HTM”) securities that are measured at amortized cost. The standard requires credit losses relating to available-for sale (“AFS”) debt securities to be recorded through an allowance for credit loss (“ACL”) rather than a reduction of the carrying amount and replaces the historically required other-than-temporary impairment (“OTTI”) analysis. It also changes the accounting for purchased credit-impaired debt securities and loans. The standard retains many of the current disclosure requirements in U.S. GAAP and expands other disclosure requirements. The new guidance is effective for calendar year-end public companies beginning January 1, 2020. Early adoption is permitted as of January 1, 2019.	January 1, 2020	Our implementation team, led jointly by Credit, Treasury, and the Corporate Controller’s group, has developed models to meet the new standard that are being validated. We have started to analyze the results of our models. Next steps include establishing and testing controls, further challenging model results, and finalizing the qualitative allowance process and disclosures. Based on our current analysis, we believe the standard may potentially have a material impact on the Bank’s financial statements, and we expect more volatility in the credit loss estimate over economic cycles. Transition to the new standard is through a cumulative-effect adjustment to the opening retained earnings as of the beginning of the first period of adoption, January 1, 2020. The Bank does not plan to early adopt this new guidance.
ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	This ASU removes the requirements in step two of the current goodwill impairment model, eliminating the requirement to calculate and compare the implied fair value of the reporting entity with the carrying amount of that entity, including goodwill, to measure any impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount of goodwill over its implied fair value of goodwill (i.e., measure the charge based on step one of the current guidance). The standard also continues to allow entities to perform an optional qualitative goodwill impairment assessment before determining whether to proceed to the quantitative step one. The standard is effective for the Bank as of January 1, 2020. Early adoption is allowed for any goodwill impairment test performed after January 1, 2017.	January 1, 2020	We do not currently expect this guidance will have a material impact on the Bank’s financial statements since the fair values of our reporting units were not lower than their respective carrying amounts of goodwill at the time of our impairment analysis for 2018 and there were no decreases in the fair value identified for the relevant reporting units in the first quarter of 2019 and there continues to be no future expected decreases the relevant fair values in the foreseeable future. The Bank is not planning to early adopt this new guidance. The transition and adoption provisions are to be applied prospectively.

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
Standards adopted by the Bank during 2019
ASU 2016-02, Leases (Topic 842) and subsequent related ASUs	Although lessor accounting was left materially unchanged by ASU 2016-02 (and all related ASUs which together have been codified in ASC 842), ASC 842 requires that all lessees recognize a right-of-use asset and an offsetting lease liability for all leases with a term greater than 12 months. As the lessee, we adopted an accounting policy election, by class of underlying asset, to not recognize lease assets or liabilities for leases with a term of 12 months or less. The recognition, measurement, and presentation of expenses and cash flows arising from a lease will depend primarily on its classification as a finance or operating lease. ASC 842 requires additional disclosures to provide financial statement users a better understanding of the amount, timing, and uncertainty of cash flows arising from leases. These new quantitative and qualitative disclosure requirements are detailed further in Note 8.	January 1, 2019	The Bank adopted ASC 842 at the beginning of the current quarter using the second of two permitted modified retrospective approaches for initial adoption. Under this method, the Bank recorded a right-of use asset of approximately $225 million and an offsetting lease liability of approximately $242 million. The impact to retained earnings upon adoption was not material. See Note 8 for additional details on the financial statement impact of completing the adoption of ASC 842.
ASU 2017-08, Nonrefundable Fees and Other Costs (Subtopic 310-20). Premium Amortization on Purchased Callable Debt Securities	The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. The standard requires the premium of qualifying debt securities to be amortized to the earliest call date. The update does not change the accounting for callable debt securities held at a discount.	January 1, 2019	We adopted this standard at the beginning of the current quarter using a modified retrospective transition approach. As a result of adoption, we recorded a $3 million decrease to retained earnings on January 1, 2019, as a cumulative effect adjustment.
ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement	The purpose of this ASU is to improve the effectiveness of disclosures in the notes to the financial statements. This Update removes, modifies, and makes certain additions to the disclosure requirements for fair value measurement. The mandatory adoption date of the guidance in this ASU is for the first fiscal period beginning after December 15, 2019, with early adoption permitted.	January 1, 2019	We early adopted this ASU in the current quarter. This standard will be applied prospectively. The changes to the disclosure requirements for fair value measurements are immaterial to the financial statements and can be found in Note 3.
ASU 2018-15, Intangibles – Goodwill and Other-Internal- Use Software (Topic 350-40): Customer’s Accounting for Implementation Cost Incurred in a Cloud Computing Arrangement That Is a Service Contract	This ASU aligns the requirements for capitalizing implementation costs associated with Cloud Computing Arrangements that meet the definition of a service contract with requirements already provided for costs associated with internal-use software. Additionally, it clarifies that: -The amortization period for capitalized amounts will be the noncancelable hosting contract term plus any expected renewal periods. -Entities in a hosting arrangement that is a service contract must provide certain qualitative and quantitative disclosures. -Transition for those not already following the provisions of this ASU can be applied either retrospectively or prospectively.	January 1, 2019	We early adopted this ASU in the current quarter. The Bank has historically been applying the guidance as clarified in this ASU. Consequently, the adoption of the ASU did not have a material impact on the Bank’s financial statements.

3. FAIR VALUE

Fair Value Measurement

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. For a discussion of the Bank’s valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 3 of our 2018 Annual Report on Form 10-K.

During the three months endedMarch 31, we recognized less than $1 million of net gains in 2019 and 2018 from the sale of OREO properties that had a carrying value, at the time of sale, of approximately $1 million during these same periods. Prior to their sale, we recognized an insignificant amount of impairment on these properties during the three months endedMarch 31, 2019 and 2018.

Private equity investments carried at cost were measured at fair value for impairment purposes according to the methodology previously discussed for these investments. Amounts of PEIs carried at cost were $10 million at March 31, 2019 and December 31, 2018. Amounts of other noninterest-bearing investments carried at cost were $272 million at March 31, 2019 and $329 million at December 31, 2018, which were comprised of Federal Reserve

42

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

and Federal Home Loan Bank (“FHLB”) stock. Private equity investments accounted for using the equity method were $36 million at March 31, 2019 and $35 million at December 31, 2018.

Impaired (or nonperforming) loans that are collateral-dependent were measured at fair value based on the fair value of the collateral. OREO was measured initially at fair value based on collateral appraisals at the time of transfer and subsequently at the lower of cost or fair value. For additional information regarding the measurement of fair value for impaired loans, collateral-dependent loans, and OREO, see Note 3 of our 2018 Annual Report on Form 10-K.

Security repurchase and reverse repurchase (“resell”) agreements are offset, when applicable, in the balance sheet according to master netting agreements. Security repurchase agreements are included with “Federal funds and other short-term borrowings.” Derivative instruments may be offset under their master netting agreements; however, for accounting purposes, we present these items on a gross basis in the Bank’s balance sheet. See Note 7 for further information regarding derivative instruments.

5. INVESTMENTS

Investment Securities

Securities are classified as HTM, AFS or trading. HTM securities, which management has the intent and ability to hold until maturity, are carried at amortized cost. AFS securities are carried at fair value and unrealized gains and losses, after applicable taxes, are recorded as net increases or decreases to accumulated other comprehensive income (“AOCI”). Realized gains and losses on AFS securities are determined by using the cost basis of each individual security. Trading securities are carried at fair value with gains and losses recognized in current period earnings. The purchase premiums for callable debt securities classified as HTM or AFS are amortized at a constant effective yield to the earliest call date. The purchase premiums and discounts for all other HTM and AFS securities are amortized and accreted at a constant effective yield to the contractual maturity date and no assumption is made concerning prepayments. As principal prepayments occur, the portion of the unamortized premium or discount associated with the principal reduction is recognized in interest income in the period the principal is reduced. Note 3 of our 2018 Annual Report on Form 10-K discusses the process to estimate fair value for investment securities.

Other-Than-Temporary Impairment

The Bank did not recognize any OTTI on its investment securities portfolio during the first three months of 2019. We review investment securities on a quarterly basis for the presence of OTTI. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At March 31, 2019, we did not have an intent to sell identified securities with unrealized losses or initiate such sales, and we believe it is not more likely than not we would be required to sell such securities before recovery of their amortized cost basis. For additional information on our policy and evaluation process relating to OTTI, see Note 5 of our 2018 Annual Report on Form 10-K.

¹Loans are presented net of unearned income, unamortized purchase premiums and discounts, and net deferred loan fees and costs totaling $51 million and $50 million at March 31, 2019 and December 31, 2018, respectively.

Municipal loans generally include loans to state and local governments (“municipalities”) with the debt service being repaid from general funds or pledged revenues of the municipal entity, or to private commercial entities or 501(c)(3) not-for-profit entities utilizing a pass-through municipal entity to achieve favorable tax treatment.

Land acquisition and development loans included in the construction and land development loan portfolio were $231 million at March 31, 2019 and $237 million at December 31, 2018.

Loans with a carrying value of approximately $23.4 billion at March 31, 2019 and $22.6 billion at December 31, 2018 have been pledged at the Federal Reserve or the FHLB of Des Moines as collateral for current and potential borrowings.

We sold loans totaling $118 million and $106 million for the three months endedMarch 31, 2019 and 2018, respectively, that were classified as loans held for sale. The sold loans were derecognized from the balance sheet. Loans classified as loans held for sale primarily consist of conforming residential mortgages and the guaranteed portion of Small Business Administration (“SBA”) loans. The loans are mainly sold to U.S. government agencies or participated to third parties. At times, we have continuing involvement in the transferred loans in the form of servicing rights or a guarantee from the respective issuer. Amounts added to loans held for sale during these same periods was $93 million and $165 million, respectively. See Note 5 for further information regarding guaranteed securities.

The principal balance of sold loans for which we retain servicing was approximately $2.2 billion at both March 31, 2019 and December 31, 2018. Income from loans sold, excluding servicing, was $2 million and $3 million for the three months endedMarch 31, 2019 and 2018, respectively.

Allowance for Credit Losses

The allowance for credit losses (“ACL”) consists of the allowance for loan and lease losses (“ALLL”) and the reserve for unfunded lending commitments (“RULC”). The ALLL represents our estimate of probable and estimable losses inherent in the loan and lease portfolio as of the balance sheet date. We also estimate a reserve for potential losses associated with off-balance sheet commitments, including standby letters of credit. We determine the RULC using the same procedures and methodologies that we use for the ALLL.

For additional information regarding our policies and methodologies used to estimate the ACL, see Note 6 of our 2018 Annual Report on Form 10-K.

Credit Quality Indicators

In addition to the past due and nonaccrual criteria, we also analyze loans using loan risk-grading systems, which vary based on the size and type of credit risk exposure. The internal risk grades assigned to loans follow our definitions of Pass, Special Mention, Sub-standard, and Doubtful, which are consistent with published definitions of regulatory risk classifications. For further discussion of our policies and processes regarding credit quality indicators and internal loan risk-grading, see Note 6 of our 2018 Annual Report on Form 10-K.

Impaired Loans

Loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement, including scheduled interest payments. Payments received on impaired loans that are accruing are recognized in interest income, according to the contractual loan agreement. Payments received on impaired loans that are on nonaccrual are not recognized in interest income, but are applied as a reduction to the principal outstanding. The amount of interest

Modified and Restructured Loans

Loans may be modified in the normal course of business for competitive reasons or to strengthen the Bank’s position. Loan modifications and restructurings may also occur when the borrower experiences financial difficulty and needs temporary or permanent relief from the original contractual terms of the loan. Loans that have been modified to accommodate a borrower who is experiencing financial difficulties, and for which the Bank has granted a concession that it would not otherwise consider, are considered troubled debt restructurings (“TDRs”). For further discussion of our policies and processes regarding TDRs, see Note 6 of our 2018 Annual Report on Form 10-K.

Unfunded lending commitments on TDRs amounted to approximately $11 million at both March 31, 2019 and December 31, 2018.

The total recorded investment of all TDRs in which interest rates were modified below market was $80 million at March 31, 2019 and $88 million at December 31, 2018. These loans are included in the previous schedule in the columns for interest rate below market and multiple modification types.

The net financial impact on interest income due to interest rate modifications below market for accruing TDRs for the three months endedMarch 31, 2019 and 2018 was not significant.

On an ongoing basis, we monitor the performance of all TDRs according to their restructured terms. Subsequent payment default is defined in terms of delinquency, when principal or interest payments are past due 90 days or more for commercial loans, or 60 days or more for consumer loans.

Concentrations of Credit Risk

Credit risk is the possibility of loss from the failure of a borrower, guarantor, or another obligor to fully perform under the terms of a credit-related contract. We perform an ongoing analysis of our loan portfolio to evaluate whether there is any significant exposure to any concentrations of credit risk. See Note 6 of our 2018 Annual Report on Form 10-K for further discussion of our evaluation of credit risk concentrations. See also Note 7 of our 2018 Annual Report on Form 10-K for a discussion of counterparty risk associated with the Bank’s derivative transactions.

7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Objectives and Accounting

The Bank is exposed to certain risks arising from both its business operations and economic conditions. Our objectives in using derivatives are to add stability to interest income or expense, to modify the duration of specific assets or liabilities as we consider advisable, to manage exposure to interest rate movements or other identified risks, and/or to directly offset derivatives sold to our customers. For a detailed discussion of the use of and accounting policies regarding derivative instruments, see Note 7 of our 2018 Annual Report on Form 10-K.

Fair Value Hedges – As of March 31, 2019, the Bank had designated $1 billion of interest rate swaps in two separate qualifying fair value hedge relationships. Each hedge has a notional amount of $500 million, with the first $500 million maturing in August of 2021 and the second $500 million maturing in February of 2022. The hedging instruments used are receive-fixed interest rate swaps designated as hedges of the change in fair value of the London Interbank Offered Rate (“LIBOR”) benchmark swap rate component of the contractual coupon cash flows of these notes. Both swaps are structured to match the critical terms of the hedged notes, resulting in the expectation that the swaps will be highly effective as hedging instruments. The first swap has a rate of 3.50%, while the second swap, which was added during the first quarter of 2019, has a receive-fixed rate of 3.35%, making the average received-fixed strike rate 3.43% for all existing fair value hedges designated at the balance sheet date.

The Bank fully amortized all debt basis adjustments from previously designed fair value hedges prior to 2018 so there is no scheduled amortization for previously terminated fair value hedges that will impact the Bank’s financial statements for the foreseeable future.

57

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

Cash Flow Hedges – During the first quarter of 2019, the Bank had two receive-fixed interest rate swaps that were designated as cash flow hedges mature. The Bank layered on an additional seven swaps in its cash flow hedge portfolio as part of its efforts to reduce asset-sensitivity and exposure to potential net interest income and margin compression in a down interest rate environment scenario. The seven additional swaps designated as cash flow hedges ranged from three to five years in tenor and increased the Bank’s overall swap notional designation in qualifying cash flow hedges of commercial loans from approximately $700 million as of December 31, 2018, to approximately $1.3 billion as of March 31, 2019. The Bank’s overall cash flow hedge swap portfolio as of the balance sheet date has a weighted-average maturity date of 2.7 years and a weighted average received-fixed strike rate of 2.08%, with a total of 22 active swaps and an additional five swaps maturing during 2019 with an aggregate notional of $150 million.

Additionally, during the first quarter of 2019, the Bank expanded its existing cash flow hedging program by introducing purchased floors as hedging instruments of its commercial loan portfolio. In total the Bank purchased $3 billion of floors with strike rates at 1.5% on one-month Intercontinental Exchange LIBOR. The $3 billion floors are composed of six individual purchased floors, all with a notional of $500 million and a tenor of approximately three years. Floors purchased were spread across the entire first quarter of 2019 and had an aggregate purchase premium of $7 million, and by March 31, 2019, the floor had increased in value to approximately $9 million dollars. The premium is amortized on a straight-line basis over the life of the derivative with changes in fair value deferred in other comprehensive income (“OCI”) as long as the hedging relationship remains highly effective and qualifies for hedge accounting. Amounts deferred in OCI are reclassified into earning in the periods in which the hedged forecasted transactions effect earnings.

Collateral and Credit Risk

Exposure to credit risk arises from the possibility of nonperformance by counterparties. No significant losses on derivative instruments have occurred as a result of counterparty nonperformance. For a more detailed discussion of collateral and credit risk related to our derivative contracts, see Note 7 of our 2018 Annual Report on Form 10-K.

Our derivative contracts require us to pledge collateral for derivatives that are in a net liability position at a given balance sheet date. Certain of these derivative contracts contain credit-risk-related contingent features that include the requirement to maintain a minimum debt credit rating. We may be required to pledge additional collateral if a credit-risk-related feature were triggered, such as a downgrade of our credit rating. However, in past situations, not all counterparties have demanded that additional collateral be pledged when provided for by the contractual terms. At March 31, 2019, the fair value of our derivative liabilities was $25 million, for which we were required to pledge cash collateral of approximately $50 million in the normal course of business. If our credit rating were downgraded one notch by either Standard & Poor’s (“S&P”) or Moody’s at March 31, 2019, there would likely be $1 million additional collateral required to be pledged. As a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”), all newly eligible derivatives entered into are cleared through a central clearinghouse. Derivatives that are centrally cleared do not have credit-risk-related features that require additional collateral if our credit rating were downgraded.

The fair value of derivative assets was reduced by a net credit valuation adjustment of $6 million and $1 million at March 31, 2019 and 2018, respectively. The adjustment for derivative liabilities was a decrease of less than $1 million at March 31, 2019 and $1 million at March 31, 2018. These adjustments are required to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk.

8. LEASES

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (“Topic 842”), to increase transparency and comparability among organizations by requiring the recognition of right-of-use assets and lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of right-of-use (“ROU”) assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases.

Upon adoption the Bank has elected to use the following optional exemptions that are permitted under Topic 842, which have been applied consistently:

• the Bank elected the optional transition method and recorded an immaterial cumulative-effect adjustment to retained earnings to recognize the appropriate amount of lease assets and liabilities on the balance sheet as of the adoption date of the standard. Prior period financial statements were not restated.

• the Bank elected the expedient package to not reassess (1) whether any existing or expired contracts are or contain leases, (2) lease classification for any existing or expired leases, and (3) initial direct costs for any existing leases.

• the Bank elected to not separate lease components from non-lease components for all classes of underlying assets for lessee or lessor transactions.

We determine if a contract is a lease or contains a lease at inception. The right to use leased assets for the lease term are considered ROU assets. Operating lease assets are included in “Other assets” while finance lease assets are included in “Premises, equipment and software, net.” Lease liabilities for operating leases are included in “Other liabilities” while finance leases are included in “Long-term debt” on our consolidated balance sheet.

Lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Because most of our leases do not provide an implicit

60

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. The lease ROU asset also incorporates any amortization incurred, including initial direct costs, and excludes lease incentives received. Our lease terms may include options to extend or terminate the lease, and the lease term incorporates these when it is reasonably certain that we will exercise these options. The Bank enters into certain lease agreements with both lease and non-lease components, which are not separated out for lessees and lessors on a relative standalone basis.

We have operating and finance leases for branches, corporate offices, and data centers. Our equipment leases are not material. At March 31, 2019, we had 433 branches, of which 276 are owned and 157 are leased. We lease our headquarters in Salt Lake City, Utah, and other office or data centers are either owned or leased.

The Bank may enter into certain lease arrangements with a term of 12 months or less, and it has elected to exclude these from capitalization. The length of our commitments for leases ranges from 2019 to 2062, some of which include options to extend or terminate the leases.

As of March 31, 2019, assets recorded under operating leases were $244 million, while assets recorded under finance leases were less than $1 million. We utilized a secured incremental borrowing rate based on the remaining term of the lease as of the effective date for the discount rate to determine our lease ROU assets and liabilities. The following schedule presents lease-related assets, their weighted average remaining life, and the weighted average discount rate.

The Bank enters into certain lease agreements where it is the lessor of real estate. Real estate leases are made from bank-owned and subleased property to generate cash flow from the property, including from leasing vacant suites in which the Bank occupies portions of the building. Operating lease income was $2 million and $3 million for the first three months of 2019 and 2018, respectively.

The Bank also has a lending division that makes equipment leases, considered to be sales-type leases or direct financing leases, totaling $312 million and $371 million as of March 31, 2019 and 2018, respectively. The Bank uses leasing of equipment as a venue for customers to access equipment without purchasing upfront. For the first quarters of 2019 and 2018, the Bank recorded income of $4 million and $3 million on these leases.

Contractual amounts of off-balance sheet financial instruments used to meet the financing needs of our customers are as follows:

(In millions)	March 31, 2019		December 31, 2018
Net unfunded commitments to extend credit 1	$	21,632	$	21,454

¹  Net of participations

The Bank’s 2018 Annual Report on Form 10-K contains further information about these commitments and guarantees including their terms and collateral requirements. At March 31, 2019, the Bank had recorded approximately $4 million as a liability for the guarantees associated with the standby letters of credit, which consisted of $1 million attributable to the RULC and $3 million of deferred commitment fees.

Legal Matters

We are subject to litigation in court and arbitral proceedings, as well as proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies. Litigation may relate to lending, deposit and other customer relationships, vendor and contractual issues, employee matters, intellectual property matters, personal injuries and torts, regulatory and legal compliance, and other matters. While most matters relate to individual claims, we are also subject to putative class action claims and similar broader claims. Proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies may relate to our banking, investment advisory, trust, securities, and other products and services; our customers’ involvement in money laundering, fraud, securities violations and other illicit activities or our policies and practices relating to such customer activities; and our compliance with the broad range of banking, securities and other laws and regulations applicable to us. At any given time, we may be in the process of responding to subpoenas, requests for documents, data and testimony relating to such matters and engaging in discussions to resolve the matters.

As of March 31, 2019, we were subject to the following material litigation or governmental inquiries:

• a civil suit, Shou-En Wang v. CB&T, brought against us in the Superior Court for Los Angeles County, Central District in April 2016. The case relates to our depositor relationships with customers who were promoters of an investment program that allegedly misappropriated investors’ funds. Initial motion practice and discovery have been completed. Additional motion practice and expert witness phases are underway.

• a civil suit, McFarland as Trustee for International Manufacturing Group v. CB&T, et. al., brought against us in the United States Bankruptcy Court for the Eastern District of California in May 2016. The Trustee seeks to recover loan payments previously repaid to us by our customer, International Manufacturing Group (“IMG”), alleging that IMG, along with its principal, obtained loans and made loan repayments in furtherance of an alleged Ponzi scheme. Initial motion practice has been completed and discovery is underway.

• a civil suit, JTS Communities, Inc. et. al v. CB&T, Jun Enkoji and Dawn Satow, brought against us in the Superior Court for Sacramento County, California in June 2017. In this case four investors in IMG seek to hold us liable for losses arising from their investments in that company, alleging that we conspired with and knowingly assisted IMG and its principal in furtherance of an alleged Ponzi scheme. This case is in an early phase with initial motion practice having been completed and discovery is underway.

• a civil class action lawsuit, Evans v. CB&T, brought against us in the United States District Court for the Eastern District of California in May 2017. This case was filed on behalf of a class of up to 50 investors in IMG

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

and seeks to hold us liable for losses of class members arising from their investments in IMG, alleging that we conspired with and knowingly assisted IMG and its principal in furtherance of an alleged Ponzi scheme. In December 2017, the District Court dismissed all claims against the Bank. In January 2018, the plaintiff filed an appeal with the Court of Appeals for the Ninth Circuit. The appeal was heard in early April 2019 and a ruling is anticipated in mid or late 2019.

• a Private Attorney General Act (“PAGA”) claim under California law, Lawson v. CB&T, brought against us in the Superior Court for the County of San Diego, California, in February 2016. In this case, the plaintiff alleges, on behalf of herself and other current or former employees of the Bank who worked in California on a non-exempt basis, violations by the Bank of California wage and hour laws. The case remains in the early stages of motion practice, to date mainly involving questions of venue and scope of employees covered by the PAGA claims. In March 2018, the Supreme Court of California granted review of an appeal from the intermediate appellate court decision requiring all aspects of the case to be heard in state court, rather than in arbitration. The appellate briefing process has been completed with a ruling anticipated in 2019.

• two civil cases, Lifescan Inc. and Johnson & Johnson Health Care Services v. Jeffrey Smith, et. al., brought against us in the United States District Court for the District of New Jersey in December 2017 and Roche Diagnostics and Roche Diabetes Care Inc. v. Jeffrey C. Smith, et. al., brought against us in the United States District Court for the District of New Jersey in March 2019. In these cases, certain manufacturers and distributors of medical products seek to hold us liable for allegedly fraudulent practices of a borrower of the Bank which filed for bankruptcy protection in 2017. The cases are in early phases, with initial motion practice and discovery underway in the Lifescan case.

• two civil class action lawsuits: Gregory, et. al. v. Zions Bancorporation and Springer, et. al. v. Zions Bancorporation, were brought against us in the United States District Court in Utah in January 2019 which have been consolidated into one case; and a separate civil action brought by a group of investors North Valley Partners, et. al. v. Zions Bancorporation, brought against us in the Third Judicial District Court for Salt Lake County, in March 2019. These cases were filed on behalf of investors in Rust Rare Coin, Inc. alleging that we aided and abetted a Ponzi scheme fraud perpetrated by Rust Rare Coin, a Zions Bank customer. The cases follow civil actions and the establishment of a receivership for Rust Rare Coin by The Commodities Futures Trading Commission and the Utah Division of Securities in November 2018, as well as a separate suit brought by the Securities and Exchange Commission against Rust Rare Coin and its principal, Gaylen Rust.

At least quarterly, we review outstanding and new legal matters, utilizing then available information. In accordance with applicable accounting guidance, if we determine that a loss from a matter is probable and the amount of the loss can be reasonably estimated, we establish an accrual for the loss. In the absence of such a determination, no accrual is made. Once established, accruals are adjusted to reflect developments relating to the matters.

In our review, we also assess whether we can determine the range of reasonably possible losses for significant matters in which we are unable to determine that the likelihood of a loss is remote. Because of the difficulty of predicting the outcome of legal matters, discussed subsequently, we are able to meaningfully estimate such a range only for a limited number of matters. Based on information available as of March 31, 2019, we estimated that the aggregate range of reasonably possible losses for those matters to be from $0 millionto roughly $50 million in excess of amounts accrued. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those matters for which a meaningful estimate is not possible are not included within this estimated range and, therefore, this estimated range does not represent our maximum loss exposure.

Based on our current knowledge, we believe that our current estimated liability for litigation and other legal actions and claims, reflected in our accruals and determined in accordance with applicable accounting guidance, is adequate and that liabilities in excess of the amounts currently accrued, if any, arising from litigation and other legal actions and claims for which an estimate as previously described is possible, will not have a material impact on our financial condition, results of operations, or cash flows. However, in light of the significant uncertainties involved in these matters, and the very large or indeterminate damages sought in some of these matters, an adverse outcome in

65

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

one or more of these matters could be material to our financial condition, results of operations, or cash flows for any given reporting period.

Any estimate or determination relating to the future resolution of litigation, arbitration, governmental or self-regulatory examinations, investigations or actions or similar matters is inherently uncertain and involves significant judgment. This is particularly true in the early stages of a legal matter, when legal issues and facts have not been well articulated, reviewed, analyzed, and vetted through discovery, preparation for trial or hearings, substantive and productive mediation or settlement discussions, or other actions. It is also particularly true with respect to class action and similar claims involving multiple defendants, matters with complex procedural requirements or substantive issues or novel legal theories, and examinations, investigations and other actions conducted or brought by governmental and self-regulatory agencies, in which the normal adjudicative process is not applicable. Accordingly, we usually are unable to determine whether a favorable or unfavorable outcome is remote, reasonably likely, or probable, or to estimate the amount or range of a probable or reasonably likely loss, until relatively late in the course of a legal matter, sometimes not until a number of years have elapsed. Accordingly, our judgments and estimates relating to claims will change from time to time in light of developments and actual outcomes will differ from our estimates. These differences may be material.

11. REVENUE RECOGNITION

We derive our revenue primarily from interest income on loans and securities, which was more than three-quarters of our revenue in the first quarter of 2019. Only noninterest income is considered to be revenue from contracts with customers in scope of ASC 606. For a discussion of the Bank’s revenue recognition from contracts, and the implementation of ASC 606, see Note 16 of our 2018 Annual Report on Form 10-K.

The following schedule provides the major income categories within “Other service charges, commissions and fees” that are in scope of ASC 606 for the three months endedMarch 31, 2019:

	Three Months Ended March 31,
(In millions)	2019		2018
Card fee income	$	34	$	33
ATM fees	2		2
Other service charges	3		4
Other commissions and fees	4		5
Total	$	43	$	44

Disaggregation of Revenue

We provide services across different geographical areas, primarily in 11 Western U.S. States, under banking operations that have their own individual brand names, including Zions Bank, Amegy Bank, California Bank & Trust, National Bank of Arizona, Nevada State Bank, Vectra Bank Colorado, and The Commerce Bank of Washington. The operating segment listed as “Other” includes Zions Management Services Company, certain nonbank financial services subsidiaries, centralized back-office functions, and eliminations of transactions between the segments. Certain prior period amounts have been reclassified to conform with the current period presentation. These reclassifications did not affect net income or shareholders’ equity.

12. RETIREMENT PLANS

The following discloses the net periodic benefit cost (credit) and its components for the Bank’s pension and other retirement plans:

Expected return on plan assets	(2		)	(3		)
Partial settlement loss	—			1
Amortization of net actuarial loss	1			—
Net periodic benefit cost (benefit)	$	—		$	(1	)

As disclosed in our 2018 Annual Report on Form 10-K, the Bank has frozen its participation and benefit accruals for the pension plan and its contributions for individual benefit payments in the postretirement benefit plan. In October 2018, the Bank has decided to terminate its pension plan subject to obtaining necessary regulatory approval. Completion of this termination is expected in early 2020. Plan participant benefits will not be disadvantaged because of this decision.

13. INCOME TAXES

The effective income tax rate of 22.3% for the first quarter of 2019 was slightly lower than the 2018first quarter rate of 22.7%. The income tax rates for 2019 and 2018 were reduced by nontaxable municipal interest income and nontaxable income from certain bank-owned life insurance, and were increased by the non-deductibility of Federal Deposit Insurance Corporation (“FDIC”) premiums, certain executive compensation and other fringe benefits.

We had a net deferred tax asset (“DTA”) balance of $73 million at March 31, 2019, compared with $130 million at December 31, 2018. The decrease in the net DTA resulted primarily from the decrease of accrued compensation and unrealized losses in OCI related to securities. A reduction of net deferred tax liabilities related to leasing operations, including deferred items associated with the adoption of ASC 842, offset some of the overall decrease in DTA.

15. OPERATING SEGMENT INFORMATION

We manage our operations and prepare management reports and other information with a primary focus on geographical area. Our banking operations are managed under their own individual brand names, including Zions Bank, Amegy Bank, California Bank & Trust, National Bank of Arizona, Nevada State Bank, Vectra Bank Colorado, and The Commerce Bank of Washington. Performance assessment and resource allocation are based upon this geographical structure. We use an internal funds transfer pricing (“FTP”) allocation system to report results of operations for business segments. This process is continually refined. Total average loans and deposits presented for the banking segments include insignificant intercompany amounts between banking segments and may also include deposits with the Other segment.

As of March 31, 2019, our banking business is conducted through 7 locally managed and branded segments in distinct geographical areas. Zions Bank operates 98 branches in Utah, 23 branches in Idaho, and one branch in Wyoming. Amegy operates 74 branches in Texas. CB&T operates 90 branches in California. NBAZ operates 58 branches in Arizona. NSB operates 50 branches in Nevada. Vectra operates 36 branches in Colorado and one branch in New Mexico. TCBW operates one branch in Washington and one branch in Oregon.

ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES

The operating segment identified as “Other” includes certain nonbank financial service subsidiaries, centralized back-office functions, and eliminations of transactions between segments. The major components of net interest income at the Bank’s back-office include the revenue associated with the investments securities portfolio and the offset of the FTP costs and benefits provided to the business segments.

The following schedule does not present total assets or income tax expense for each operating segment, but instead presents average loans, average deposits and income before income taxes because these are the metrics that management uses when evaluating performance and making decisions pertaining to the operating segments. The Bank’s net interest income includes interest expense on borrowed funds. The condensed statement of income identifies the components of income and expense which affect the operating amounts presented in the Other segment.

The accounting policies of the individual operating segments are the same as those of the Bank. Transactions between operating segments are primarily conducted at fair value, resulting in profits that are eliminated for reporting consolidated results of operations.

The following schedule presents selected operating segment information for the three months ended March 31, 2019 and 2018:

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate and market risks are among the most significant risks regularly undertaken by us, and they are closely monitored as previously discussed. A discussion regarding our management of interest rate and market risk is included in the section entitled “Interest Rate and Market Risk Management” in this Form 10-Q.

ITEM 4. CONTROLS AND PROCEDURES
