CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES
The Company has made no significant changes in its critical accounting policies and significant estimates from those disclosed in its 2016 Annual Report on Form 10-K.
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 CompanyBank 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 CompanyBank and for presentations of CompanyBank performance to investors. The CompanyBank further believes that presenting these non-GAAP financial measures will permit investors to assess the performance of the CompanyBank 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 the non-GAAP financial measures presented in this Form 10-Q and a discussion of whythe 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 adjustments,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 Company’sBank’s use of shareholders’ equity. Management believes the use of ratios that utilize tangible equity provides additional useful information about performance 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,” “taxable-equivalent net interest income,” “adjusted taxable-equivalent revenue,” “pre-provision net revenue" (“PPNR”) and “adjusted pre-provision net revenue (“PPNR”).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 CompanyBank is managing its expenses, and adjusted PPNR enables management and others to assess the Company’sBank’s ability to generate capital to cover credit losses through a credit cycle. Taxable-equivalent net interest income allows management to assess the comparability of revenue arising from both taxable and tax-exempt sources. The efficiency ratio and adjusted noninterest expense are the key metrics to which the Company announced it would hold itself accountable in its June 1, 2015 efficiency initiative, and to which executive compensation is tied.

RESULTS OF OPERATIONS
Executive Summary
The financial performance in the second quarter of 2020 reflected the continued deterioration in the economic environment due to the COVID-19 pandemic. The slowing of economic activity and rising unemployment rate contributed to a $168 million provision for credit losses. Rapidly decreasing interest rates drove our loan yields down more quickly than our deposit rates, leading to a 31 basis point decline in our net interest margin, which was 3.23% in the second quarter. The decline in the net interest margin was largely offset by strong loan and deposit growth, which were significantly assisted by the PPP. Core customer-related fee income was stable despite the economic weakness, while overall fee income was down due to declining values in our Small Business Investment Company portfolio and credit-related valuations in our customer interest rate swap exposure. Noninterest expenses were well controlled, due in part to the reductions in staff announced in late 2019, and also included a one-time pension plan termination-related expense of $28 million.
COVID-19 Pandemic
In the latter part of the first quarter of 2020, the COVID-19 pandemic manifested its impact on individuals, companies, and governments around the world. It has significantly curtailed the global economy and created a challenging operating environment. As economic conditions deteriorated in mid-March, we responded rapidly with some key modifications to adjust to the change in the operating environment:
For our employees:
Enhanced the ability of our employees to work remotely, adjusting branch operating hours and restricting lobby access in many cases.
Provided significant support to employees by granting an increase in flexibility with paid leave, temporarily adjusting vacation policies, and increasing the cleaning of facilities to enable a safer environment for those employees who are not able to work from home.
Paid enhanced overtime for employees working on PPP loans and announced a $1,000 bonus to each of our employees with annualized compensation of less than $150,000 to be paid later this year.
For our customers and communities:
Provided short-term loan payment and fee forbearance programs. Many borrowers requested and received temporary forbearance from obligations to assist them with the expected shortage in their near-term cash flow.
Moved certain offshore operations domestically to ensure that information security standards are met and that our customers are provided with the service and support they need.
Facilitated government programs. See "SBA Paycheck Protection Program" in this section for more information.
Provided support to our communities and we announced $30 million in future charitable contributions from the loan processing fees received from the PPP loans.
For our shareholders and regulators:
Maintained our capital ratios at strong levels and materially augmented our allowance for credit losses ("ACL"), increased the ACL by $388 million, or 74%, since January 1, 2020.
Reduced costs where possible, which included reductions in incentive compensation linked to profitability and credit quality performance for certain executives.

Select Industries with Elevated Risk Related to COVID-19
We believe select industries have elevated risk due to the COVID-19 pandemic, and as a result, we are more closely managing our credit exposure to these industries, including having completed detailed industry credit reviews during the quarter. The following chart shows $4.2 billion, or 8.6%, of the Bank's non-PPP loan balances as of June 30, 2020, in these select industries. Approximately 29% of these loans were modified or deferring payments, and 97% were secured by collateral. The oil and gas-related industry has also been affected by the COVID-19 pandemic and a resulting global imbalance of supply and demand. For more information see "Oil and Gas-Related Exposure" on page 25 of Management's Discussion and Analysis.
zions-20200630_g1.jpg
Line utilization for the COVID-19 selected industries declined approximately nine percentage points from March 31, 2020 to June 30, 2020. For information on loan modifications related to COVID-19 see "COVID-19 modifications" on page 30 of Management's Discussion and Analysis.
SBA's Paycheck Protection Program
During the second quarter of 2020, we provided assistance to many small businesses through the PPP. This program provides small businesses with funds to be used for certain expenses as defined by the SBA.
As of June 30, 2020, we had processed approximately $7 billion of PPP loans for more than 46,000 customers, which included more than 10,000 new customers. We are working diligently to solidify those new relationships. We ranked ninth by dollar volume of all the participating financial institutions, as disclosed by the SBA. Payments by borrowers on the loans will begin six months after the note date, while interest at 1%, will continue to accrue during the six-month deferment. Loans can be forgiven in whole or part (up to full principal and any accrued interest).
Loan processing fees paid to the Bank from the SBA are accounted for as loan origination fees. These fees, net of loan origination costs, are deferred and recognized over the life of the loan as a yield adjustment. If a loan is paid off or forgiven by the SBA prior to its maturity date, the remaining unamortized net deferred fees will be recognized in

Federal Reserve's Main Street Lending Program
We are a participant in the Federal Reserve's Main Street Lending Program to support lending to small and medium-sized businesses and nonprofit organizations that were in sound financial condition before the onset of the COVID-19 pandemic. As of June 30, 2020, we had not funded any loans under this program.

Net earnings decreased from the second quarter of 2019 to the second quarter of 2020 primarily from an increase in the provision for credit losses. The increase in net earnings from the first quarter of 2020 to the current period was primarily due to a lower provision for credit losses.The increased provision for credit losses in the first and second quarters of 2020 compared with the second quarter of 2019 is primarily due to experienced and expected economic deterioration caused by the COVID-19 pandemic and stress in the oil and gas-related sector.PPNR increased from both the first quarter of 2020 and the second quarter of 2019. The increase in adjusted PPNR from the same prior year period is primarily a result of a $21 million decrease in adjusted noninterest expense, partially offset by a $15 million decrease in adjusted taxable-equivalent revenue.Our efficiency ratio improved from both the first quarter of 2020 and the second quarter of 2019. The improvement from the same prior year period is a result of expense control, including a reduction in workforce during the fourth quarter of 2019.
The Bank reported net earnings applicable to common shareholders for the third quarter of 2017 were $152$57 million, or $0.72$0.34 per diluted common share for the second quarter of 2020, compared with net earnings applicable to common shareholders of $154$189 million, or $0.73$0.99 per diluted common share for the second quarter of 2017, and $1172019.
During this time of economic uncertainty, we have materially strengthened our allowance for credit losses. Charge-offs were $31 million or $0.57 per diluted common share forduring the thirdsecond quarter of 2016. Interest income of $5572020, compared with $14 million in the third quarter of 2017 improved $66 million overduring the same prior year period, mainlyperiod.
We entered the current economic environment with a strong capital and reserve position, a robust liquidity profile, and a loan portfolio that has been substantially “de-risked” in recent years and that largely tends to have collateral as a secondary source of repayment – a characteristic that has historically resulted in lower loss rates per dollar of troubled loans.
Net income decreased by $132 million to $66 million in the second quarter of 2020 from $198 million in the second quarter of 2019, primarily due to growtha $147 million increase in our loansthe provision for credit losses, $28 million of expense related to the previously announced pension plan termination, and securities portfoliosa decrease of $15 million in total noninterest income. These decreases were partially offset by a $42 million reduction in income taxes, a $10 million increase in loan-related fees and short-term rate increases that positively impacted loan yields. income, and a $7 million decrease in salaries and employee benefits.

Net income for the first six months of 2020 was $80 million, compared with $411 million for the first six months of 2019. The provision for credit losses increased by $401 million during this same time period to $426 million from $25 million and was the primary reason for the decrease in net income.

Performance Against Previously Announced Initiatives
In June 2015, we announced several initiatives to improve operational and financial performance along with some key financial targets. Our initiatives are designed to improve customer experience, to simplify the corporate structure and operations, and to make the Company a more efficient organization. Following is a brief discussion regarding current performance against these key financial targets.
Achieve an efficiency ratio in the low 60% range for fiscal year 2017. Our efficiency ratio for the third quarter of 2017 was 62.3%, a 365 bps improvement over the same prior year period efficiency ratio of 65.9%. Our year-

Improvements in interest income from securities and loans, partially offset by increasesa decrease in adjustedinterest expense of $83 million. Both were impacted from lower benchmark interest rates. Interest income also benefited from loan growth of 13%, largely from PPP loans.

Adjusted noninterest expense resulteddecreased by $21 million in the significant improvement.same period, reflecting expense control and the reduction in workforce announced in October 2019. The Bank’s efficiency ratio was 57.3% in the second quarter of 2020 compared with 59.0% in the second quarter of 2019 and 57.7% in the first quarter of 2020. See “GAAP to Non-GAAP Reconciliations” on page 56 for more information regarding the calculation of the adjusted PPNR and the efficiency ratio and why management uses this non-GAAP measure.ratio.
Maintain adjusted noninterest expense at less than $1.58Our average loan portfolio increased $5.9 billion, in 2016, with a modest increase of 2-3% in 2017. We met our target for fiscal year 2016, keeping adjusted noninterest expense to $1.579 billion. Through September 30, 2017, adjusted noninterest expense was $1.225 billion, compared with $1.185 billion for the same prior year period. In the most recent quarter, we incurred $6 million of non-recurring expenses due to Hurricane Harvey’s impact on the Houston area. Despite these additional expenses, our adjusted noninterest expense should increase by 2-3% in 2017.
Highlights from the Third Quarter and First Nine Months of 2017
Net interest income, which is more than three-quarters of our revenue, was $522 million in the third quarter of 2017 and $469 million in the third quarter of 2016. This 11.3% increase over the same prior year period is due to our efforts to change the mix of interest-earning assets from lower-yielding money market investments into higher-yielding investment securities and loans. Net interest margin was 3.45% in the third quarter of 2017, compared with 3.36% in the third quarter of 2016. Year-to-date net interest income was $1.5 billion in 2017 and $1.4 billion for the same prior year period. The 11.0% increase between the two periods was mainly impacted by growth in our loans and securities portfolios and short-term rate increases that positively impacted loan yields.
Adjusted PPNR of $251 million for the third quarter of 2017 was up $42 million, or 20.1%12%, from the thirdsecond quarter of 2016, primarily as a result2019, with PPP loans accounting for $5.0 billion, or 84% of increasesthe growth. The yield on average loans decreased by 102 bps, reflecting the decline in netbenchmark interest income. Although adjusted noninterest expense also increased overrates. Overall, from the same period, from $404 million in the thirdsecond quarter of 20162019 to $414 million in the most recent quarter, increases in income more than offset the increase in expense. The higher adjusted PPNR in the thirdsecond quarter of 2017,2020, classified loans increased by $707 million, or 92%, and nonaccrual loans increased by $91 million, or 37%. The ratio of net loan charge-offs to average loans was 0.23% for the second quarter of 2020, compared with 0.12% for the same prior year period, drove an improvement in the Company’s efficiency ratio from 65.9% in the thirdsecond quarter of 20162019. Unfunded lending commitments increased $0.9 billion, or 3.9%, to 62.3% in the current quarter. Year-to-date adjusted PPNR was $732 million in 2017$24.2 billion at June 30, 2020 from $23.3 billion at June 30, 2019.
At June 30, 2020, oil and $602 million in 2016, representing a 21.6% increase. Increases were driven by similar factors to those previously discussed. See “GAAP to Non-GAAP Reconciliations” on page 5 for more information regarding the calculationgas-related loans represented 5% of adjusted PPNR.
Asset quality for the total loan portfolio, continues to strengthen. Classified and nonaccrual loans improved as a percentagecompared with 8% at December 31, 2014, or the beginning of outstanding balances by 97 bps and 27 bps, respectively, between the third quarterslast energy cycle. Since December 31, 2014, the mix of 2016 and 2017. In recent quarters, asset quality in our oil and gas-related portfolioloans has been substantially weaker than it has been in non-oilshifted toward lower risk loans and gas-related loans. At the same time, the Company has reduced its oil and gas-related exposure by $253 million since the third quarter of 2016 and oil prices have stabilized since their low point in early 2016. Classified and nonaccrual balances in the oil and gas-related portfolio have decreased since the third quarter of 2016 by 35.8% and 39.6%, respectively. These improvementsour underwriting standards for these loans have been the drivers of a lower provision for credit losses, which was $1 million in the current quarter and $16 million in the same prior year period.
Loans have grown $1.6 billion, or 3.8% since the third quarter of 2016, despite targeted declines in certain areas due to portfolio and concentration risk management. Aside from declines in our national real estate (“NRE”), oil and gas-related, and commercial real estate (“CRE”) portfolios, this growth has been widespread across most other products, with particular strength in 1-4 family residential, commercial and industrial, and municipal lending.
We continue to increase the return on and of capital. Return on average tangible common equity was 9.8%, up 189 bps from the same prior year period. During the quarter, the Company repurchased 2.5 million shares of common stock under its 2017 capital plan (which spans the timeframe of July 2017 to June 2018). Dividends per common share were $0.12 in the third quarter of 2017, compared with $0.08 for the prior quarter and the same prior year period.

Noninterest expense increased to $413 million from $403 million for the same prior year period, representingWe started 2020 with a 2.5% increase, which is generally in line with announced forecasts. Incentive compensation expense was higher this quarter than in the same prior year period. These increases were partially offset by a decline in other noninterest expense primarily due to legal accruals that occurred in the third quarter of 2016. Adjusted noninterest expense, which excludes severance and some other items as explained in the “GAAP to Non-GAAP Reconciliations” sectioncontinued focus on page 5, increased 2.5% over the same period. We expect to achieve our goal of limiting adjusted noninterest expense growth to 2-3% in 2017 when compared with 2016.

Net Interest Income and Net Interest Margin
Net interest income is the difference between interest earned on interest-earning assets and interest paid on interest-bearing liabilities. Taxable-equivalent netliabilities and is more than three-quarters of our revenue. Net interest income is derived from both the largest portionvolume of our revenue. For the third quarter of 2017, taxable-equivalent netinterest-earning assets and interest-bearing liabilities and their respective yields/rates.

The linked quarter decrease was primarily due to $16 millionlower interest rates, with yields on loans and securities declining more than the rates paid on deposits and borrowed funds. The impact of lower interest income recoveriesrates was partially offset by loan growth, primarily PPP loans, and a shift in the prior quarter, which did not repeat. Between the third quarters of 2016 and 2017, taxable-equivalentliability balances from borrowed funds to lower-cost deposits.
The net interest income increased $55 million, which was driven by a larger securities portfolio, growthmargin (“NIM”) decreased to 3.23% in the lending portfolio, and increases in short-term rates, which improved loan yields. We expect the size of the securities portfolio to be relatively stable during the next several quarters and we are not assuming any further increases in benchmark interest rates. Therefore, we expect net interest income to increase only moderately over the next twelve months.

Average noninterest-bearing deposits comprised 46% and Market Risk Management” on page 30.
The42% of average balance of long-term debt was $297 million lowertotal deposits for the thirdsecond quarters of 2020 and 2019, respectively. The net impact of noninterest-bearing sources of funds on the NIM was 0.16% during the second quarter of 20172020, compared with 0.50% during the same prior year period, assecond quarter of 2019, reflecting a resultdecline in the value of early callsthese funds.
Average borrowed funds decreased by $3.0 billion from the second quarter of 2019 to the second quarter of 2020, with average short-term borrowings decreasing $3.6 billion, and maturities.average long-term borrowings increasing by $0.6 billion, reflecting less reliance on short-term borrowings and deposit growth. During 2019 the Bank issued $500 million of senior notes with an interest rate of 3.35% and $500 million of subordinated notes with an interest rate of 3.25%. Both of these note issuances were originally accompanied by fair value swap hedges which effectively transformed the borrowing cost to variable-rate. In late March 2020, we terminated the swaps which resulted in a reduction to the effective interest rate on the debt. For more information the termination of these swaps see Note 7 – Derivative Instruments and Hedging Activities. During the second quarter of 2020 the Bank repurchased and retired $210 million and $219 million principal amount of its 3.35% and 3.50% senior notes, respectively. The average

Average short-term borrowings increased $4.3 billion. Further changes in short-term borrowing will be driven by balancing changes in deposits and loans as we do not foresee significant increases in investment security balances.second quarter of 2020 due to lower benchmark interest rates.
The spread on average interest-bearing funds was 3.26%3.07% and 3.23%3.04% for the thirdsecond quarters of 20172020 and 2016,2019, respectively. The spread on average interest-bearing funds for these periods was affected by the same factors that had an impact onimpacted the NIM.
Interest rate spreads and marginmargins are impacted by the mix of assets we hold, the composition of our loan and securities portfolios, and the type of funding we use. We expect some modest resistance to increased spreads due to both a change in the mix of the portfolio (increasing concentration in lower-yielding residential mortgages), as well as older, higher-yielding loans maturing or paying down and being replaced with new, lower-yielding loans. Generally, the new loans are of a higher credit quality than the maturing loans, which has resulted in lower-yielding loans.
used. Our estimates of the Company’sBank’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. In addition, our modeled projections for noninterest-bearing demand deposits, which are a substantial portion of our deposit balances, are particularly reliant on assumptions for which there is little historical experience due to the prolonged period of very low interest rates. Further detail on interest rate risk is discussed in “Interest Rate and Market Risk Management” on page 30.
Refer to the “Liquidity Risk Management” section beginning on page 34 for more information on how we manage liquidity risk.31.

Provision for Credit Losses
The allowance for credit losses (“ACL”) is the combination of both the allowance for loan and lease losses (ALLL) and the reserve for unfunded lending commitments (RULC). The ALLL represents the estimated current expected credit losses over the contractual term of the loan and lease portfolio as of the balance sheet date. The RULC represents the estimated reserve for current expected credit losses associated with off-balance sheet commitments. Changes in the ALLL and RULC, including changes in net charge-offs, are recorded in the provision for loan and lease losses and the provision for unfunded lending commitments in the income statement, respectively. The ACL for debt securities is estimated separately from loans.

The provision for credit losses, which is the combination of both the provision for loan losses and the provision for unfunded lending commitments.commitments, was $168 million in the second quarter of 2020, compared with $21 million in the second quarter of 2019 and $258 million in the first quarter of 2020. The ACL increased $351 million to $914 million at June 30, 2020, compared with $563 million at June 30, 2019. The increase in the ACL is primarily due to experienced and expected economic deterioration caused by the COVID-19 pandemic, and stress in the oil and gas-related sector. The provision for loancredit losses isfor debt securities was less than $1 million in the second quarter of 2020.
On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and its subsequent updates, often referred to as the Current Expected Credit Loss ("CECL") accounting standard. Upon adoption of the ASU, Zions recorded the full amount of expense that,the ACL for loans and leases of $526 million, compared with $554 million at December 31, 2019, resulting in an after-tax increase to retained earnings of $20 million. The impact of the adoption of CECL for our judgment, is required to maintainsecurities portfolio was less than $1 million. As a result of this new accounting standard, we expect our ACL will become more volatile primarily because, under the new process, the allowance for loan and lease losses (“ALLL”) at an adequate level based on the inherent risks in the loan portfolio. The provision for unfunded lending commitments is usedsubject to maintain the reserve for unfunded lending commitments (“RULC”) at an adequate level based on the inherent risks associated with such commitments. In determining adequate levels of the ALLL and RULC, we perform periodic evaluations of our various loan portfolios, the levels of actual charge-offs, credit trends, and external factors. See economic forecasts that may change materially from period to period.
Note 6 of our 20162019 Annual Report on Form 10-K and “Credit Risk Management” on page 20 for more24 contains information on how we determine the appropriate level for the ALLL and the RULC.
The provision Also, for loan losses was $5 million in the third quarter of 2017, compared with $19 million in the same prior year period. Strong overall credit quality, including steady improvement in the oilmore information see "Critical Accounting Policies and gas-related portfolio have led to lower modeled reserves, requiring a lower provision. Nonaccrual and classified loans both decreased between the two periods by $98 million and $367 million, respectively. Net charge offs also declined $22 million over the same timeframe. The Company has roughly $8 billion of loan balances in the geographic area impacted by Hurricane Harvey. We have reached out to many of our customers to understand their concerns and to offer reasonable assistance. Using multiple top-down and bottom-up analyses to estimate losses resulting from the hurricane, we have added a qualitative allowance of $34 million.Significant Estimates" on page 41.
During the third quarter of 2017, we recorded a $(4) million provision for unfunded lending commitments, compared with a $(3) million provision in the third quarter of 2016. 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 ACL, which is the combination of both the ALLL and the RULC, decreased $59 million when compared with the third quarter of 2016. Even with loan growth and the above-mentioned hurricane impact, robust credit quality and decreased net charge-offs in the total loan portfolio were responsible for much of this reduction. Further, declining oil and gas-related exposure and increasing non-oil and gas-related C&I and 1-4 family residential mortgage exposure improved the risk profile of the portfolio.

Noninterest income represents revenues we earn for products and services that have no associated interest rate or yield. For the third quarter of 2017,Growing noninterest income decreased $6 million, or 4.1% compared with the third quarter of 2016. Through September 30, 2017, year-to-date noninterest income increased $16 million, or 4.1%, compared with the first nine months of 2016. Noninterest income decreased compared with the third quarter of 2016 dueis a key strategic priority, and several strategic initiatives are underway to lower loan sales volume, decreased deposit fees, and a decline in net securities gains.

support this effort, although growth has been impacted by the effects of COVID-19. Specifically, we are working to leverage our focus on commercial and small business customers to accelerate sales of capital markets products and wealth advisory services. Noninterest income accounted for 17% and 19% of net revenue during the second quarters of 2020 and 2019, respectively. Noninterest income was $117 million for the second quarter of 2020, compared with $132 million for the second quarter of 2019.
We believe a subtotal of customer-related fees provides a better view of income over which we have more direct near-term control. It excludes items such as dividends, insurance-related income, mark-to-market adjustments on certain derivatives, and securities gains and losses. Customer-related fees were stable at $130 million during both the second quarters of 2020 and 2019. Non customer-related fees decreased $4by $15 million from the thirdsecond quarter of 2016. Service charges on deposit accounts decreased largely2019 to the second quarter of 2020.

Loan-related fees and income increased $10 million from the second quarter of 2019 to the second quarter of 2020 due to increased earnings credits on analyzed business accounts. Loan sales and servicing income declined primarily becausestrength in residential mortgage banking activity, including loan sales, volume was downwhich benefited from an unusually high amountthe reduction in benchmark interest rates. Due to the waiving of fees for customers during the early stages of the COVID-19 pandemic, we experienced a $5 million decrease from the second quarter of 2019 to the second quarter of 2020 in retail and business banking fees, mostly attributable to lower insufficient fund fees, as well as a $4 million decrease in card fees from reduced economic activity and transaction volume in the thirdsecond quarter of 20162020. Capital markets and aforeign exchange fees decreased by $2 million lossfrom the second quarter of 2019 to the second quarter of 2020, due largely to reduced loan syndication fees.
In the second quarter of 2020, the Bank recognized a $12 million negative credit valuation adjustment (“CVA”) on client-related interest rate swaps, compared with a loan classified as held for sale$6 million negative CVA in the most recentprior year period. The year-to-date declineThis change reflects the Bank’s growing customer-related credit exposure to interest rate swaps. Dividends and other income decreased from $11 million in loan sales and servicing income wasthe second quarter of 2019, to $3 million in the second quarter of 2020, due to similar factors. We continue to see steady improvement in credit card interchangeadverse market valuations on certain Small Business Investment Company (“SBIC”) investments and lower dividends received from the Federal Home Loan Bank (“FHLB”), reflecting less FHLB activity stock held by the Bank.
Customer-related fees for the first six months of 2020 increased by $19 million primarily from loan-related fees and are growing our wealth managementincome and trust businesses. We expect moderate growthcapital markets and foreign exchange fees, partially offset by a decrease in customer-relatedcard fees over the next twelve months.and loan-related fees and income.

We have previously forecast increases in noninterest expense for 2017. Noninterest expense increased primarily as a result of a $28 million pension plan termination-related expense recognized in Other noninterest expense. The pension plan termination included a $17 million reclassification out of accumulated other comprehensive income and into Other noninterest expense, resulting in a pre-tax decrease in shareholders’ equity of $11 million. Salaries and employee benefits decreased by $10$7 million, overprimarily from lower overall incentive compensation, although there were increases for certain compensation pools, such as those related to PPP loans. Full-time equivalent employees decreased from 10,326 to 9,859 from the thirdsecond quarter of 20162019 to the second quarter of 2020 primarily as a result of the 5% workforce reduction announced in October 2019. However, base salaries did not decline 5% from the prior year second quarter due to the effects of inflation and $51 millionmerit increases.
The Bank’s efficiency ratio was 57.3% in the second quarter of 2020 compared with 59.0% in the first nine months of 2016. Expenses increased in most areas, but were most impacted by higher FDIC premiums, salaries and benefits, and occupancy costs.
Salary and benefits expense was up $11 million from the thirdsecond quarter of 2016,2019 and $14 million year to date. Elevated noninterest expense57.7% in the third quarter of 2016 was partially offset by a lower accrual for incentive compensation; this reduction did not occur in the most recent quarter. In 2017, we have also experienced a higher volume of medical claims in the Company’s self-funded healthcare plan.
Occupancy expense increased $2 million from the third quarter of 2016, and increased $8 million compared with the first nine months of 2016. The increase was primarily due to damage to buildings caused by Hurricane Harvey. In the first quarter of 2017, we also placed a newly constructed office building into operation in Houston2020. The efficiency ratio and have incurred additional depreciation and other transition expenses as a result. The Company has several signed leases with tenants, and as those tenants move in, we expect additional rental income to mostly offset the increase we have observed thus far in 2017.
We implemented the first release of the TCS BαNCS core servicing system during the second quarter. Associated amortization of the costs capitalized during development caused most of the $3 million variance from the third quarter of 2017 in furniture, equipment and software expense.
The Company’s provision for unfunded lending commitments has remained relatively steady over the past twelve months. We released $1 million more of our reserve through the provision for unfunded lending commitments

ZIONS BANCORPORATION AND SUBSIDIARIES

compared with the third quarter of 2016, and released $7 million less compared with the first nine months of 2016. Credit concerns in the oil and gas-related portfolio have stabilized as oil prices have rebounded. Refer to the Provision for Credit Losses section above for more details.
FDIC premium expense increased $3 million or 25.0% from the third quarter of 2016, and $12 million, or 42.9%, compared with the first nine months of 2016. Expense increased in both cases due to a higher deposit base and the FDIC surcharge. The FDIC approved a change in deposit insurance assessments that implemented a Dodd-Frank Act provision requiring banks with over $10 billion in assets to recapitalize the FDIC insurance fund to 1.35% over an eight-quarter period, after it reached a 1.15% reserve ratio. The 1.15% threshold was reached at the end of the second quarter of 2016 and the increased premium has been effective since then.
Other noninterest expense decreased $7 million over the third quarter of 2016 and $2 million, compared with the first nine months of 2016. A limited increase in losses due to Hurricane Harvey in the most recent quarter was more than offset by lower operational losses and legal reserves. No single item had a significant impact on the year-to-date variance.
Our goal is to limit adjusted noninterest expense growth to 2-3% in 2017 as we continue to invest in people and technology. For the first nine months of 2017, adjusted noninterest expense was $1.225 billion and we are committed to achieving our target. 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 56 for more information regarding the calculation of the efficiency ratio).
Income Taxes
Income tax expense for the thirdsecond quarter of 20172020 was $83$16 million compared with $65$58 million for the same prior year period.period as a result of lower income during the second quarter of 2020. The effective income tax rates were 34.2%19.5% and 33.9%22.7% for the thirdsecond quarters of 20172020 and 2016, respectively. 2019, respectively, as a result of the proportional increase in nontaxable items and tax credits relative to pretax book income as compared to the prior year period.
Income tax expense for the first six months of 2020 was $207$18 million compared to $119 million for the first ninesix months of 2017 and $166 million for the first nine months of 2016.2019. The effective tax rates for these year-to-date periods were 30.6%18.4% and 33.3%22.5%, respectively. Tax rates generally benefited fromNote 13 of the nontaxability of certain income items. 2017 rates were further impacted byNotes to Consolidated Financial Statements contains additional information about the following factors:
We reevaluated our state tax positions infactors that influenced the first quarter of 2017, which resulted in a one-time $14 million tax benefit.
We reduced income tax expense by $4 million in the second quarter of 2017 due to changes in the carrying value of various staterates and information about deferred income tax items.
We recorded an $8 million benefit in the first nine months of 2017, from the implementation of new accounting guidance related to stock-based compensation.
We had a net deferred tax asset (“DTA”) balance of $207 million at September 30, 2017, compared with $250 million at December 31, 2016. The decrease in the DTA resulted primarily from net charge-offs exceeding the provision for loan losses, the payout of accrued compensation,assets and the reduction of unrealized losses in other comprehensive income (“OCI”) related to securities. A decrease in deferred tax liabilities during 2017, which related to premises and equipment and the deferred gain on a prior period debt exchange, offset some of the overall decrease in DTA.liabilities.

Infor both the second quarters of 20172020 and 2016, the Company redeemed preferred stock of $144 million and $118 million, respectively. The total one-time reduction to net earnings applicable to common shareholders associated with preferred stock redemptions was $2 million for the 2017 redemption and $10 million for the 2016 redemption, primarily due to the accelerated recognition of preferred stock issuance costs.2019.

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 nonearningnon-earning 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 11.16.
Average interest-earning assets were $60.6$68.1 billion for the first ninesix months of 2017,2020, compared with $55.7$64.7 billion for the first ninesix months of 2016.2019. Average interest-earning assets as a percentage of total average assets for the first ninesix months of 20172020 and 20162019 were 93.4%93% and 93.7%94%, respectively.
Average loans were $43.2$51.5 billion and $41.9$47.8 billion for the first ninesix months of 20172020 and 2016,2019, respectively. Average loans as a percentage of total average assets for the first ninesix months of 20172020 were 66.6%71%, compared with 70.4%69% in the same prior year period.
Average money market investments, consisting of interest-bearing deposits, federal funds sold, and security resell agreements, decreasedincreased by 61.0%43% to $1.6$1.8 billion for the first ninesix months of 2017,2020, compared with $4.1$1.3 billion for the first ninesix months of 2016.2019.

The investment securities portfolio includes $576$315 million of net premium that is distributed across various asset classes as illustrated in the preceding schedule. The purchase premiums and discountsPremium amortization for both held-to-maturity (“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 as interest income in the period the principal is reduced. For the three and nine months ended SeptemberJune 30, 2017, premium amortization reduced the yield on securities by 89 and 90 bps, respectively,2020, was $25 million, compared with a 117 bps and 110 bps impact$31 million for the same periodsperiod in 2016.

Net premises, equipment, and software increased $63$31 million, or 6.2%2.7%, during the first ninesix months of 2020. In 2017, primarily duethe Bank implemented the first phase of its 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 CRE lending systems. With this milestone reached, we now have substantially all our retail, commercial and CRE 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 associated withis 10 years.

Deposits
Deposits, both interest-bearing and noninterest-bearing, are a primary source of funding for the Company.Bank. Average total deposits for the first ninesix months of 20172020 increased by 4.2%11%, compared with the first ninesix months of 2016,2019, with average interest-bearing deposits increasing by 3.9%9% and average noninterest-bearing deposits increasing by 7.4%14%. The increases in interest and noninterest-bearing deposits were driven by increases in both personal and business customer balances. The ending interest-bearing deposits balance at September 30, 2017 decreased by 0.4% to $28.1 billion from $28.2 billion at June 30, 2017. The decrease in ending balance is mainly due to the natural daily volatility of deposits and certain customers sweeping funds off of our balance sheet to take advantage of higher rates in the capital markets. The average interest rate paid for interest-bearing deposits was 336 bps higherlower during the first ninesix months of 2017,2020, compared with the first ninesix months of 2016.
Deposits at September 30, 2017, excluding time deposits $100,000 and over and brokered deposits, decreased slightly to $50.4 billion from $51.4 billion at December 31, 2016. The decrease was mainly due to a decrease in interest-bearing domestic savings and money market deposits.2019.
Demand, and savings, and money market deposits were 94.4%94% and 94.8%92% of total deposits at SeptemberJune 30, 20172020 and December 31, 2016,2019, respectively.

See “Liquidity Risk Management” on page 3436 for additional information on funding and borrowed funds.
RISK ELEMENTS
Since risk is inherent in substantially all of the Company’sBank’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 Company’sBank’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 Company’sBank’s operations are exposed, including credit risk, interest rate and market risk, liquidity risk, strategic risk, business and operational risks.corporate governance risk, operational/technology risk, cyber risk, capital/financial reporting risk, legal/compliance risk (including regulatory risk); and reputational risk. These risks are overseen by the various management committees of which the Enterprise Risk Management Committee (“ERMC”) is the focal point for the monitoring and review of enterprise risk. For a more comprehensive discussion of these risks, see “Risk Factors” in our 2019 Annual Report on Form 10-K.
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.
The Board of Directors, through the ROC, is responsible for approving the overall credit policies relating to the management of the credit risk of the Company. In addition, the ROC oversees and monitors adherence to key credit policies and the credit risk appetite as defined in the Risk Appetite Framework. Additionally, the Board has established the Credit Administration Committee, chaired by the Chief Credit Officer and consisting of members of management, to which it has delegated the responsibility for managing credit risk for the Company and approving changes to the Company’s credit policies.

ZIONS BANCORPORATION AND SUBSIDIARIES

Centralized oversight For a more comprehensive discussion of credit risk is provided through credit policies, credit risk management, and credit examination functions. Our credit polices place emphasissee “Credit Risk Management” in our 2019 Annual Report on strong underwriting standards and early detection of potential problem credits in order to develop and implement action plans on a timely basis to mitigate any potential losses. These formal credit policies and procedures provide the Company with a framework for consistent underwriting and a basis for sound credit decisions at the local banking affiliate level.Form 10-K.
Our credit risk management function is separate from the lending function and strengthens control over, and the independent evaluation of, credit activities. In addition, we have a well-defined set of standards for regularly evaluating our loan portfolio, and we utilize a comprehensive loan risk-grading system to determine the risk potential in the portfolio. Furthermore, the internal credit examination department, which is independent of the lending function, periodically conducts examinations of the Company’s lending departments and credit activities. These examinations are designed to review credit quality, adequacy of documentation, appropriate loan risk-grading administration, and compliance with credit policies. New, expanded, or modified products and services, as well as new lines of business, are approved by the New Initiative Review Committee.
Our credit risk management strategy includes diversification of our loan portfolio. We attempt to avoid the risk of an undue concentration of credits in a particular collateral type or with an individual customer or counterparty. Generally, our loan portfolio is well diversified; however, due to the nature of our geographical footprint, there are certain significant concentrations, primarily in CRE and oil and gas-related lending. We have adopted and adhere to concentration limits on leveraged lending, municipal lending, oil and gas-related lending, and various types of CRE lending, particularly construction and land development lending. All of these limits are continually monitored and revised as necessary. The recent growth in construction and land development loan commitments is within the established concentration limits. Our business activity is primarily with customers located within the geographical footprint of our banking affiliates.
As we continue to monitor our concentration risk, the composition of our loan portfolio has slightly changed. Oil and gas-related loans represented 4.6% of the total loan portfolio at September 30, 2017, compared with 5.1% at December 31, 2016. Total commercial and CRE loans were 51.0% and 25.2% of the total portfolio at September 30, 2017, compared with 50.6% and 26.6%, at December 31, 2016, respectively. Consumer loans have grown to represent 23.8% of the total loan portfolio at September 30, 2017, compared with 22.8% at December 31, 2016.

The increase in unfunded oil and gas-related lending commitments was primarily in the midstream portfolio.
Classified oil and gas-related credits decreased to $492 million at September 30, 2017, from $681 million at December 31, 2016. Oil and gas-related loan net charge-offs were $6 million in the third quarter of 2017, predominantly in the oil and gas services portfolio, compared with $16 million in the fourth quarter of 2016 and $41 million in the third quarter of 2016.
Nonaccruing oil and gas-related loans decreased by $85 million from the fourth quarter of 2016, primarily in the oil and gas services portfolio. Approximately 68% of oil and gas-related nonaccruing loans were current as to principal and interest payments at September 30, 2017, which declined from 86% at December 31, 2016.

For the second quarter of 2020, the commitments less than $30 million. Additionally, there are instances where we have commitments to companies with a common sponsor, which, if combined, would result in higher commitment levels than $30 million. The portfolio contains only senior loans – no junior or second lien positions; additionally, we cautiously approach making first-lien loans to borrowers that employ excessive leverage through the use of junior lien loans or unsecured layers of debt. Approximately 87% of the totalclassified oil and gas-related portfolio is secured by reserves, equipment, real estate, and other collateral, or a combination of collateral types.
We participate as a lender in loans and commitments designated as Shared National Credits (“SNCs”)loan ratio was 8.3%, which generally consist of larger and more diversified borrowers that have better access to capital markets. SNCs are loans or loan commitments of at least $20 million that are shared by three or more federally supervised institutions. The percentage of SNCs is 80% of the upstream portfolio, 80% of the midstream portfolio, and 46% of the oil and gas services portfolio. Our bankers have direct access and contact with the management of these SNC borrowers, and as such, are active participants. In many cases, we provide ancillary banking services to these borrowers, further evidencing this direct relationship. The results of the recent SNC exam are reflected in our financial statements.
As a secondary source of support, many of ourhad no oil and gas-related borrowers have access to capital marketsnet charge-offs, and private equity sources. Private sponsors tend to be large funds, often with assets under management of more than $1 billion, managed by individuals with a great deal of oil and gas expertise and experience and who have successfully managed investments through previous oil and gas price cycles. The investors in the funds are primarily institutional investors, such as large pensions, foundations, trusts, and high net worth family offices.
When establishing the level of the ACL, we consider multiple factors, including reduced drilling activity and additional capital raises by borrowers and their sponsors. The ACL related to the oil and gas portfolio remains above 7% for the third quarter of 2017.gas-related loans was 5.7%

At June 30, 2020, our CRE construction and land development and term loan portfolios represent approximately 22% of the total loan portfolio. The majority of our CRE loans are secured by real estate located within our geographical footprint. Approximately 21%25% of the CRE term loans consist of mini-perm loans as of September 30, 2017. For such loans, construction has been completed andloan portfolio matures in 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 tonext 12 months. Construction

seven years. The remaining 79% ofand land development loans generally mature in 18 to 36 months and contain full or partial recourse guarantee structures with one to five-year extension options or roll-to-perm options that often result in term debt. Term CRE loans aregenerally mature within a three to seven-year period and consist of full, partial, and non-recourse guarantee structures. Typical term loans with initial maturities generally of 5 to 20 years. The stabilization criteria for a project to qualify for a termCRE loan differ by product type andstructures include criteria related to the cash flow generated by the project,annually-tested operating covenants that require loan rebalancing based on minimum debt service coverage, debt yield, or loan-to-value ratio, and occupancy rates.tests.
Approximately $134$142 million, or 9%6%, of the commercial construction and land development portfolio at SeptemberJune 30, 20172020 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.
Of the total CRE loan portfolio we categorize $1.9 billion as retail property. At September 30, 2017, approximately $339 million, or 18%, For a more comprehensive discussion of the retail CRE loans, are secured by regional shopping centers.
Underwriting on commercial properties is primarily based onsee the economic viability of the project with heavy consideration given to the creditworthiness and experience of the sponsor. We generally require that the owner’s equity be injected prior to bank advances. Remargining requirements (required equity infusions upon a decline in value or cash flow of the collateral) are often included in the loan agreement along with guarantees of the sponsor. Recognizing that debt is paid via cash flow, the projected cash flows of the project are critical in the underwriting because these determine the ultimate value of the property and its ability to service debt. Therefore, in most projects (with the exception of multifamily and hospitality construction projects), we require substantial pre-leasing/leasing“Commercial Real Estate Loans” section in our underwriting and we generally require a minimum projected stabilized debt service coverage ratio of 1.20 or higher, depending2019 Annual Report on the project asset class.Form 10-K.
Within the residential construction and development sector, many of the requirements previously mentioned, such as creditworthiness and experience of the developer, up-front injection of the developer’s equity, principal curtailment requirements, and the viability of the project are also important in underwriting a residential development loan. Significant consideration is given to the forecasted market acceptance of the product, location, strength of the developer, and the ability of the developer to stay within budget. Progress inspections by qualified independent inspectors are routinely performed before disbursements are made.
Real estate appraisals are ordered in accordance with regulatory guidelines and are validated independent of the loan officer and the borrower, generally by our internal appraisal review function, which is staffed by licensed appraisers. In some cases, reports from automated valuation services are used or internal evaluations are performed. A new appraisal or evaluation is required when a loan deteriorates to a certain level of credit weakness.
Advance rates (i.e., loan commitments) will vary based on the viability of the project and the creditworthiness of the sponsor, but our guidelines generally limit advances to 50% for raw land, 65% for land development, 65% for finished commercial lots, 75% for finished residential lots, 80% for pre-sold homes, 75% for models and homes not under contract, and 75% for commercial properties. Exceptions may be granted on a case-by-case basis.
Loan agreements require regular financial information on the project and the sponsor in addition to lease schedules, rent rolls and, on construction projects, independent progress inspection reports. The receipt of this financial information is monitored and calculations are made to determine adherence to the covenants set forth in the loan agreement.
The existence of a guarantee that improves the likelihood of repayment is taken into consideration when analyzing CRE loans for impairment. If the support of the guarantor is quantifiable and documented, it is included in the potential cash flows and liquidity available for debt repayment, and our impairment methodology takes this repayment source into consideration.
When we modify or extend a loan, we also give consideration to whether the borrower is in financial difficulty, and whether we have granted a concession. In determining if an interest rate concession has been granted, we consider whether the interest rate on the modified loan is equivalent to current market rates for new debt with similar risk characteristics. If the rate in the modification is less than current market rates, it may indicate that a concession was granted and impairment exists. However, if additional collateral is obtained, or if a guarantor exists who has

Table of Contents
ZIONS BANCORPORATION AND SUBSIDIARIES

capacity and willingness to support the loan on an extended basis, we also consider the nature and amount of the additional collateral and guarantees in the ultimate determination of whether a concession has been granted.
In general, we obtain and consider updated financial information for the guarantor as part of our determination to extend a loan. The quality and frequency of financial reporting collected and analyzed varies depending on the contractual requirements for reporting, the size of the transaction, and the strength of the guarantor.
Complete underwriting of the guarantor includes, but is not limited to, an analysis of the guarantor’s current financial statements, leverage, liquidity, global cash flow, global debt service coverage, contingent liabilities, etc. The assessment also includes a qualitative analysis of the guarantor’s willingness to perform in the event of a problem and demonstrated history of performing in similar situations. Additional analysis may include personal financial statements, tax returns, liquidity (brokerage) confirmations, and other reports, as appropriate.
A qualitative assessment is performed on a case-by-case basis to evaluate the guarantor’s experience, performance track record, reputation, and willingness to work with us. We also utilize market information sources, rating, and scoring services in our assessment. This qualitative analysis coupled with a documented quantitative ability to support the loan may result in a higher-quality internal loan grade, which may reduce the level of allowance we estimate. Previous documentation of the guarantor’s financial ability to support the loan is discounted if there is any indication of a lack of willingness by the guarantor to support the loan.
In the event of default, we evaluate the pursuit of any and all appropriate potential sources of repayment, which may come from multiple sources, including the guarantee. A number of factors are considered when deciding whether or not to pursue a guarantor, including, but not limited to, the value and liquidity of other sources of repayment (collateral), the financial strength and liquidity of the guarantor, possible statutory limitations (e.g., single action rule on real estate) and the overall cost of pursuing a guarantee compared with the ultimate amount we may be able to recover. In other instances, the guarantor may voluntarily support a loan without any formal pursuit of remedies.
A decrease in oil and gas prices could potentially produce an adverse impact on our CRE loan portfolio within Texas. However, based upon generally strong equity and cash flow coverage levels, and sponsor support for the various properties, we do not expect a material amount of losses within this portfolio for the remainder of 2017. Our largest CRE credit exposures in Texas are to the multi-family, office, and retail sectors. As of September 30, 2017, the CRE loan portfolio mix in Texas is 68% commercial term, 19% commercial construction, 10% residential construction, and 3% land development.
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 Septemberboth June 30, 2017,2020 and December 31, 2019, our HECL portfolio totaled $2.7 billion, compared with $2.6 billion at December 31, 2016.$2.9 billion.

At SeptemberJune 30, 2017,2020, loans representing approximatelyless 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 91%89% of our HECL portfolio is still in the draw period, and approximately 24%18% 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 ninesix months of 20172020 and 20162019 for the HECL portfolio was (0.01)%0.00% and 0.02%(0.02)%, respectively.

Nonperforming Assets
Nonperforming assets as a percentage of loans and leases and other real estate owned decreased(“OREO”) increased to 1.06%0.62% at SeptemberJune 30, 2017,2020, compared with 1.34%0.51% at December 31, 2016.2019.
Total nonaccrual loans at SeptemberJune 30, 2017 decreased $1042020 increased $96 million from December 31, 2016,2019, primarily in the commercial and industrial loan portfolio. However, nonaccrual loans slightly increased in the commercial owner-occupiedportfolio at Amegy and commercial real estate term loan portfolios. The largest total decrease in nonaccrual loans occurred at Amegy.Vectra.
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. Company policy does not allow for the conversion of nonaccrual construction and land development loans to CRE term loans. See also Note 6 of the Notes to Consolidated Financial Statements for more information on nonaccrual loans.

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 $3increased $132 million, or 1.2%86%, during the first ninesix months of 2017.2020. 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.

COVID-19 modifications
As described previously, we developed various debt relief programs for our borrowers that have been adversely impacted by the COVID-19 pandemic. These programs primarily began in the second quarter of 2020 and generally consisted of short-term, or 90-day, principal and interest loan payment deferrals. Consistent with accounting and regulatory guidance, loan modifications provided to borrowers experiencing financial difficulties exclusively related to the COVID-19 pandemic, in which we provided these short-term modifications or payment deferrals, are not classified as TDRs. Approximately 8.5% of total loan balances (across most loan products and industries) have been processed for modifications or payment deferrals as of June 30, 2020.
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.

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 sensitiverate-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 incomefixed-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.

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 year,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 higherlower rates on net interest income growth.contraction. We continue to anticipate highermoderately lower net interest income in a risingthe current rate environment as the rate earned on our assets reprice more quickly thancontinue to decline. Due to our liabilities.
As most of our liabilities are comprised of indeterminate maturity and managed rateconcentration in noninterest-bearing deposits behavioral assumptions for these deposits have a significant impactas well as the low interest rates paid on our projectedinterest-bearing deposits, there is little room to reduce deposit costs.
At December 31, 2019 we had $1.5 billion of fixed-to-floating interest rate risk. We have historically reportedswaps hedging long-term debt (effectively converting the fixed-rate debt into floating-rate debt). In late March 2020, we terminated $1.0 billion of swaps (i.e. two sets$500 million swaps with maturities in August 2021 and February 2022) with a combined fair value of deposit assumptions, fast$36 million that adjusted the carrying value of the debt by the same amount. The basis adjustment will be amortized as an adjustment to interest expense through the maturity of the debt, thereby reducing the effective interest rate.

For commercial checking deposits, we have separated the balances into a core amount that is operational or that compensatescollateral settlements for billed services, and a complementary excess balance. The excess balance is modeled with a high attrition rate, whereas the core balance runs off more slowly. For other deposit types, the core balance is determined by the average balance over a longer-term horizon, typically 24 to 48 months, and excess balances are modeled with a high attrition rate.centrally cleared derivatives.
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”). Earnings at RiskEaR 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.
Earnings at RiskEaR is an estimate of the change in total net interest income that would be recognized under different interest rate environments. Earnings at Riskenvironments over a one-year period. This simulated impact to net interest income due to a change in rates uses as its base a modeled net interest income that is measured assumingnot necessarily the same as the most recent quarter's or year's reported net interest income. Rather, EaR employs estimated net interest income under an unchanged interest rate scenario as the basis for comparison. The EaR process then simulates changes to the base net interest income under several interest rate 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 ratelower-rate environment). The EaR model does not contemplate changes in fee income that are amortized into interest income (e.g. premiums, discounts, origination points and costs, etc.). Our policy contains a trigger for a 10% decline in rate sensitiverate-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 and into 2020. As of June 30, 2020 the EaR declined by 1% for a 200 bps decline in rates.
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 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

Table of Contents
ZIONS BANCORPORATION AND SUBSIDIARIES

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. TheAs 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, that do not have specific maturities, 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 tofor 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 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 CDs.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 towith 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 the shape of the yield curve, competitive pricing, money supply, credit worthiness of the Company,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.

The asset sensitivity as measured by EaR increased quarter over quarter primarily due to changes in the deposit beta for money market accounts. The lower beta is consistent with our prior experience with the federal funds target rate in the range of 0%-0.25%.
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.

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 our 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.

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.

These PEIs are subject to the provisions of the Dodd-Frank Act. The Volcker Rule of the Dodd-Frank Act prohibits banks and bank holding companies from holding PEIs, except for SBIC funds and certain other permitted exclusions, beyond a required deadline. The Federal Reserve Board (“FRB”) announced in December 2016 that it would allow banks to apply for an additional five-year extension beyond the July 21, 2017 deadline to comply with the Dodd-Frank Act requirement for these investments. The Company applied for and was granted an extension for its eligible PEIs. All positions in the remaining portfolio of PEIs are subject to the extended deadline or other applicable exclusions.
As of September 30, 2017, such prohibited PEIs amounted to $4 million, with an additional $4 million of unfunded commitments (see Note 5 of the Notes to Consolidated Financial Statements for more information). We currently do not believe that this divestiture requirement will ultimately have a material impact on our financial statements.

The policy requires the Company to maintain a bufferstress tests and assess its portfolio of highly liquid assets sufficient to cover cash outflows in the event of a severe liquidity crisis. The Company targets a buffer of highly liquid assets at the Parent to cover 18-24 months of cash outflows under a scenario with limited cash inflows, and maintains a minimum policy limit of not less than 12 months. Throughout the first nine months of 2017 and as of September 30, 2017, the Company complied with this policy. More information regarding the Company’s liquidity risk management process is contained in “Liquidity Risk Management” under “Overview” in our 2016 Annual Report on Form 10-K.
Liquidity Regulation
In September 2014, U.S. banking regulators issued a final rule that implements a quantitative liquidity requirement in the U.S. generally consistent with the LCR minimum liquidity measure established under the Basel III liquidity framework. Under this rule, we are subject to a modified LCR standard, which requires a financial institution to hold an adequate amount of unencumbered High-Quality-Liquid Assets (“HQLA”) that can be converted into cash easily and immediately in private markets to meet its liquidity needs for a short-term liquidity stress scenario. This rule became applicable to us on January 1, 2016.
The Basel III liquidity framework includes a second minimum liquidity measure, the Net Stable Funding Ratio (“NSFR”), which requires a financial institution to maintain a stable funding profile over a one-year period in relation to the characteristics of its on- and off-balance sheet activities. On October 31, 2014, the Basel Committee on Banking Supervision issued its final standards for this ratio, entitled Basel III: The Net Stable Funding Ratio. On May 3, 2016, the FRB issued a proposal requiring bank holding companies with less than $250 billion of assets, but more than $50 billion of assets, to cover 70% of 1-year cash outflows under the assumptions required in the proposed NSFR Rule. Under the proposal, bank holding companies would be required to publicly disclose information about the NSFR levels each quarter. The proposal has an effective date of January 1, 2018. We continue to monitor this proposal and any other developments. Based on this Basel III publication and the FRB proposal, we believe we would meet the minimum NSFR if such requirement were currently effective.
The Enhanced Prudential Standards for liquidity management (Reg. YY) require us to conduct monthly liquidity stress tests. These tests incorporate scenarios designed by us, require a buffer of highly liquid assets sufficient(sufficient to cover 30-day funding needs under the stress scenarios,scenarios). At June 30, 2020, our investment securities portfolio of $15.0 billion and are subject to review by the FRB. cash and money market investments of $2.4 billion collectively comprised 23% of total assets.
The Company’s internal liquidity stress-testing program as contained in its policy complies with these requirements and includes monthly liquidity stress testing using a set of internally generated scenarios representing severe liquidity constraints over a 12-month horizon.

During the first nine months of 2017, our HTM and AFS investment securities increased by $1.7 billion. This increase was primarily due to purchases of short-to-medium duration agency guaranteed mortgage-backed securities. Prior to the second quarter of 2017, we were adding to our investment portfolio during the past couple of years to increase our HQLA position in light of the new LCR rules and more broadly, to manage balance sheet liquidity more effectively. However, during the second and third quarters of 2017, our HTM and AFS investment securities decreased by $432 million, and we expect the size of the investment portfolio to be generally stable during the next several quarters.
During the first nine months of 2017 we made cash payments totaling $153 million for our long-term debt which matured and did not incur any new long-term debt during the same time period. See Note 8 for additional detail about debt maturities. During the first nine months of 2017, we also increased our short-term debt with the FHLB by $2.8 billion, and had $3.3 billion outstanding as of September 30, 2017.
Parent Company Liquidity
The Parent’s cash requirements consist primarily of debt service, investments in and advances to subsidiaries, operating expenses, income taxes, and dividends to preferred and common shareholders. The Parent’s cash needs are usually met through dividends from its subsidiaries, interest and investment income, subsidiaries’ proportionate shares of current income taxes, and long-term debt and equity issuances.

During the second quarter of 2020, the Federal Reserve established the Payroll Protection Program Liquidity Facility (“PPPLF”). Zions has the ability to pledge loans it has made under the PPP to the PPPLF and receive term funding matching the term of the pledged loans for the full balance of PPP loans held by the Bank.

OperationalOperational/Technology and Cyber 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 FDICIA.
To manage and minimize our operational risk, we have in place transactional documentation requirements; systems and procedures to monitor transactions and positions; systems and procedures to detect and mitigate attempts to commit fraud, penetrate our systems or telecommunications, access customer data, and/or deny normal access to those systems to our legitimate customers; regulatory compliance reviews; and periodic reviews by the Company’sBank’s Compliance Risk Management, Internal Audit and Credit Examination departments. Reconciliation procedures have been established to ensure that data processing systems consistently and accurately capture critical data. In addition, the Data Governance department has key governance surrounding data integrity and availability. Further, we have key programs and procedures to maintain contingency and business continuity plans for operational support in the event of natural or other disasters. We also mitigate operational risk through the purchase of insurance, including errors and omissions and professional liability insurance.
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 Operational Risk Committee reports to the ERMC, which reports to the ROC. Key measures have been established to increase oversight by ERM and Operational Risk Management through the strengthening of new initiative reviews, enhancements to the Enterprise Procurement and Third Party Risk Management framework, enhancements to the Business Continuity and Disaster Recovery programs and Enterprise Security programs, and the establishment of Fraud Risk Oversight, Incident Response Oversight and Technology

Significant enhancements have also been made to governance, technology, and reporting, including the establishment of Policy and Committee Governance programs, the implementation of a governance, risk and control solution, and the creation of an Enterprise Risk Profile and an Operational Risk Profile along with business line risk profiles. In addition, the establishment of an Enterprise Exam Management department has standardized our response and reporting, and increased our effectiveness and efficiencies with regulatory examinations, communications and issues management.

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. We entered the economic downturn resulting from the COVID-19 pandemic with a strong capital position.
Capital Planning and Stress Testing
As a bank holding company (“BHC”) with assets greater than $50 billion, we are requiredThe Bank’s primary regulator is the OCC. The Bank continues to be subject to examinations by the Dodd-FrankCFPB with respect to consumer financial regulations. Under the National Bank Act and OCC regulations, certain capital transactions may be subject to participate in annualthe approval of the OCC.
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 results of our internal stress tests known asare publicly available on the Dodd-Frank Act Stress Test (“DFAST”). In addition, we are required to participate in the Federal Reserve Board’s annual Comprehensive Capital AnalysisBank's website. The timing and Review (“CCAR”), which is also recently referenced as the Horizontal Capital Review (“HCR”) for large and non-complex firms (generally, BHCs, with assets between $50 billion and $250 billion). In ouramount of capital plan, we are required to forecast, under a variety of economic scenarios, our estimated regulatory capital ratios, including our Common Equity Tier 1 ratio. Under the implementing regulations for CCAR, BHCs may generally raise and redeem capital, pay dividends, and repurchase stock and take similar capital-related actions only under a capital plan as to which the FRB has not objected. A detailed discussion of CCAR/DFAST requirements is contained on page 10 of the “Capital Plan and Stress Testing” section under Part 1, Item 1 in our 2016 Annual report on Form 10-K.
We submitted our stress test results and 2017 capital plan to the FRB on April 5, 2017. On June 28, 2017, the Board of Governors of the Federal Reserve System notified Zions Bancorporation that the Federal Reserve does not object to Zions Bancorporation’s Board-approved 2017 capital plan. Our capital plan for the period spanning July 1, 2017 through June 30, 2018 includes up to $465 million of common stock repurchases and approximately $140 million of common stock dividends as follows.
Increasing the quarterly common dividend to $0.24 per share by the second quarter of 2018 following the path of:
$0.12 per share in the third quarter of 2017
$0.16 per share in the fourth quarter of 2017
$0.20 per share in the first quarter of 2018
$0.24 per share in the second quarter of 2018
Capital actions are subject to final approval by Zions Bancorporation’s board of directors, and may be influenced by, among other things, actual earningsvarious factors, including the Bank's financial performance, business needs, prevailing and prevailinganticipated economic conditions.
On June 22, 2017, we filed a Form 8-K presenting the results of the 2017 DFAST exercise. The results of Zions’ published stress tests demonstrate that the Company believes it has sufficient capital to withstand a severe hypothetical economic downturn. Detailed disclosure of the stress test results can be found on our website.
On June 29, 2016, we filed a Form 8-K announcing that the FRB did not object to our 2016 capital plan (which spans the timeframe of July 31, 2016 to June 30, 2017). The plan included (1) the increase of the quarterly common

As planned, our quarterly dividend on common stock increased to $0.12 per share during the third quarter of 2017. The quarterly dividend had been $0.08 per share since the third quarter of 2016. The Company has repurchased $115 million of our common stock at an average price of $45.45 per share under the 2017 capital plan and $180 million of our common stock at an average price of $35.66 per share under the 2016 capital plan. The Company has $350 million of buyback capacity remaining in its 2017 capital plan.
Also in accordance with our 2016 capital plan, we redeemed all outstanding shares of our 7.9% Series F preferred stock on the redemption date of June 15, 2017. Note 8 contains additional information about the redemption.

The Basel III capital rules will be fully phased in on January 1, 2019. In 2013, the FRB, FDIC,conditions, and OCC published final rules (the “Basel III Capital Rules”) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implemented the Basel Committee’s December 2010 framework, commonly referred to as Basel III, for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act.approval.
A detailed discussion of Basel III requirements, including implications for the Company, is contained on page 9 in “Capital Standards – Basel Framework” under Part 1, Item 1 in our 2016 Annual Report on Form 10-K.
We met all capital adequacy requirements under the Basel III Capital Rules based upon phase-in rules as of September 30, 2017, and believe that we would meet all capital adequacy requirements on a fully phased-in basis if such requirements were currently effective.

In July 2020 the Board of Directors declared a quarterly dividend of $0.16$0.34 per common share payable on November 22, 2017August 20, 2020 to shareholders of record on November 15, 2017. WeAugust 13, 2020. The Bank also paid dividends on preferred stock of $32$17 million for both the first ninesix months of 2017 compared to $40 million during the first nine months of 2016.2020 and 2019. See Note 89 for additional detail about capital management transactions during the first ninesix months of 2017.2020.
Basel III Capital RatiosRequirements
Banking organizations are required byThe Bank is subject to Basel III capital regulationsrequirements to maintain adequate levels of capital as measured by several regulatory capital ratios. We met all capital adequacy requirements under the Basel III Capital Rules as of June 30, 2020. The following schedule showspresents the Company’sBank’s capital and performance ratios as of SeptemberJune 30, 2017,2020, December 31, 2016,2019 and SeptemberJune 30, 2016.2019.
A final rule adopted by the federal banking agencies in February 2019 provides banking organizations with the option to phase in, over a three-year period, the adverse day-one regulatory capital effects of the adoption of CECL. On March 27, 2020, the federal banking agencies issued an interim final rule that gives banking organizations that implement CECL before the end of 2020 the option to reduce for two years a portion of CECL’s adverse effect on regulatory capital. This is in addition to the three-year transition period already in place, resulting in an optional five-year transition. We adopted the provisions of this guidance beginning with the first quarter 2020 financial statements. As a result, we will delay recognizing the full amount of the June 30, 2020 impact of the ACL on regulatory capital until after a two-year deferral period, which for us extends through December 31, 2021. Beginning on January 1, 2022, we will be required to phase in 25% of the previously deferred estimated capital impact of the ACL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025. At June 30, 2020, the application of these provisions improved our CET1, Tier 1 risk-based and Total risk-based capital ratios by 14 basis points each, and improved our Tier 1 leverage capital ratio by 9 basis points.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ESTIMATES
ITEM 1.
FINANCIAL STATEMENTS (Unaudited)
On January 1, 2020, we adopted ASU 2016-13, or CECL. Upon adoption of the ASU, we recorded the full amount of the ACL for loans and leases of $526 million, compared with $554 million at December 31, 2019, resulting in an after-tax increase to retained earnings of $20 million. The impact of the adoption of CECL for our securities portfolio was less than $1 million.
The CECL allowance is calculated based on quantitative models and management qualitative judgment based on many factors over the life of loan. The primary assumptions of the CECL quantitative model are the economic forecast, the length of the reasonable and supportable forecast period, the length of the reversion period, prepayment rates, and the credit quality of the portfolio.
As a result of this accounting standard, we expect our ACL will become more volatile primarily because, under the new methodology, the allowance is subject to economic forecasts that may change materially from period to period. Although we believe that our methodology for determining an appropriate level for the allowance adequately addresses the various components that could potentially result in credit losses, the processes and their elements include features that may be susceptible to significant change. Any unfavorable differences between the actual outcome of credit-related events and our estimates could require an additional provision for credit losses.
We estimate CECL over the contractual remaining life of each loan, which considers historical credit loss experience, current conditions, and reasonable and supportable forecasts about the future. We use the following two types of credit loss estimation models:
Econometric loss models, which rely on statistical analyses of our historical loss experience dependent upon economic factors and other loan-level characteristics. Statistically relevant economic factors vary depending upon the type of loan, but include variables such as unemployment, real estate price indices, energy prices, GDP, etc.
Loss models that are based on our long-term average historical credit loss experience since 2008, which rely on statistical analyses of our historical loss experience dependent upon loan-level characteristics.
Estimated credit losses during the first 12 months of a loan’s contractual remaining life, or reasonable and supportable period, are derived from the econometric loss models. Over a subsequent 12-month reversion period, we blend the estimated credit losses from the two models on a straight-line basis. For the remaining life of the loan, the estimated credit losses are derived from the long-term average historical credit loss models.
In addition to our quantitative allowance for loan losses, we also consider other qualitative and environmental factors related to current conditions and reasonable and supportable forecasts that may indicate current expected credit losses may differ from the historical information reflected in our quantitative models. Although the qualitative process is subjective, it represents our best estimate of qualitative factors impacting the determination of the ACL as of the financial reporting date.
Note 6 of the Notes to Consolidated Financial Statements and “Credit Risk Management” on page 24 contain further information and more specific descriptions of the processes and methodologies used to estimate the allowance for credit losses.

1.BASIS OF PRESENTATION
1. BASIS OF PRESENTATION
The accompanying unaudited consolidated financial statements of Zions Bancorporation, (“the Parent”)National Association and its majority-owned subsidiaries (collectively “Zions Bancorporation, N.A.,” “the Company,” “Zions,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 (“EITF”). In certain cases, ASUs are issued jointly with International Financial Reporting Standards (“IFRS”).Force.
Operating results for the ninesix months ended SeptemberJune 30, 20172020 and 20162019 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, 20162019 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 Company’s 2016Bank’s 2019 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. Additionally, effective October 1, 2019, we made certain financial reporting changes and reclassifications to noninterest income in our Consolidated Statements of Income. These changes and reclassifications were adopted on a retrospective basis. The changes and reclassifications reflect changes only to noninterest income in the Consolidated Statements of Income and do not impact net income, net interest income or noninterest expense.

Standards not yet adopted by the Company
ASU 2014-09, Revenue from Contracts with Customers2020-04, Reference Rate Reform (Topic 606) and subsequent related ASUs


The core principle848): Facilitation of the new guidanceEffects of Reference
Rate Reform on Financial Reporting
As part of reference rate reform, the London Interbank Offered Rate ("LIBOR") is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expectsexpected to be entitled in exchange for those goodsdiscontinued by December 31, 2021 and is being replaced by observable or services. The banking industry does not expect significant changes because major sourcestransaction-based alternative reference rates less susceptible to manipulation. This ASU addresses certain operational accounting concerns of revenue are from financial instruments that have been excluded from the scope of the new standard, (including loans, derivatives, debt and equity securities, etc.). However, these new standards affect other fees charged by banks,modifying contracts such as asset management fees, credit card interchange fees, deposit account fees, etc. Adoption maydebt, lease, and derivative agreements that reference LIBOR, or another rate, that is expected to be made on a full retrospective basis with practicaldiscontinued due to reference rate reform.

The ASU provides temporary optional expedients or on a modified retrospective basis with a cumulative effect adjustment.
January 1, 2018Approximately 85% of our revenue, including all of our interest income and a portion of our noninterest income, is out of scope of the guidance. The contracts that are in scope of the guidance are primarily related to service charges and fees on deposit accounts, wealth management income, and other service charges, commissions and fees. We have completed our review of these contracts and have not identified any material changes in the timing of revenue recognition. We plan to adopt this guidance using the modified retrospective transition method, and we expect to expand our qualitative disclosures of revenue recognition upon adoption.
ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities
The standard provides revised accounting guidance relatedexceptions to the accounting requirements for contract modifications for contracts that reference LIBOR. This ASU also provides for a one-time election to sell or transfer to available-for-sale or trading certain qualifying held-to-maturity ("HTM") debt securities. Additionally, this guidance provides various optional expedients for hedging relationships affected by reference rate reform.
April 1, 2020We adopted ASU 2020-04 on April 1, 2020; the impact upon adoption was not significant as no practical expedients were applied in the current period, but will be applied in future periods.

To date, the Bank has identified a significant number of contracts referencing LIBOR across various business units
and reportingcontract types. Additionally, the Bank’s designated hedging relationships utilize LIBOR-indexed derivatives and hedge the LIBOR exposure of financial instruments. Somefloating-rate commercial loans and the Bank’s fixed-rate debt. Remediation of these LIBOR exposures will constitute a significant operational effort. While the full impact of reference rate reform is still being determined, the application of the main provisions include:
– Equity investments that do not result in consolidationASU and are not accounted for underits practical expedients will significantly reduce the equity method would be measured at fair value through net income
– Changes in instrument-specific credit risk foroperational and financial liabilities that are measured under the fair value option would be recognized in other comprehensive income (“OCI”).
– Eliminationstatement impact of the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost. However, it will require the use of exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes.
January 1, 2018We do not have a significant amount of equity securities classified as available-for-sale (“AFS”). Additionally, we do not have any financial liabilities accounted for under the fair value option. Therefore, the transition adjustment upon adoption of this guidance is not expected to be material. We are refining our valuation models to better account for an exit price, but do not expect a significant change in our disclosure.
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities
The purpose of this standard is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The standard is effective for public business entities for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. The standard requires a modified retrospective transition method that requires recognition of the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption.January 1, 2018While we continue to assess all potential impacts of the standard, we currently do not expect adoption of this guidance to have a material impact on our consolidated financial statements. We are still evaluating when to adopt this guidance.

Standards not yet adopted by the Company (continued)
ASU 2016-02, Leases (Topic 842)The standard requires that a lessee recognize assets and liabilities for leases with lease terms of more than 12 months. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, the standard will require both types of leases to be recognized on the balance sheet. It also requires disclosures to better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements, providing additional information about the amounts recorded in the financial statements.January 1, 2019We are currently evaluating the potential impact of this guidance on the Company’s financial statements. As of December 31, 2016, the Company had minimum noncancelable net operating lease payments of $275 million that are being evaluated. The implementation team is working on gathering all key lease data elements to meet the requirements of the new guidance. Additionally, we are implementing new lease software that will accommodate the new accounting requirements.
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 to be amortized to the earliest call date. The update does not change the accounting for securities held at a discount.January 1, 2019Our initial analysis suggests this guidance will not have a material impact on the Company’s financial statements, but we will continue to monitor its impact as we move closer to implementation.

Instead, entities wouldwill 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 1step one of the current guidance).

3. FAIR VALUE
Standards adopted by the Company
ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting
The standard requires entities to recognize the income tax effects of share-based awards in the income statement when the awards vest or are settled (i.e. the additional paid-in capital pools will be eliminated). The standard provides an entity the option to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The standard also requires that excess tax benefits be reflected in the operating section of the statement of cash flows rather than the investing section and to make an election to adopt this requirement either on a retrospective or prospective basis.January 1, 2017Upon adoption of this ASU, there was no material impact from the cumulative effect adjustment to retained earnings. We elected to account for forfeitures when they occur and to reflect excess tax benefits in the operating section of the statement of cash flows on a prospective basis.
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 Company’sBank’s valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 203 of our 20162019 Annual Report on Form 10-K.

Private Equity Investments
Private equity investments are generally measured underThe Bank’s Level 3. Certain investments that have converted to being publicly traded are measured under Level 1. The majority of these3 holdings include private equity investments (“PEIs”) are held in Zions’ Small Business Investment Company (“SBIC”), agriculture loan servicing, and are early stage venture investments. The fair value measurements of these investments are updated at least on a quarterly basis, including whenever a new round of financing occurs. Certain of these investments are measured using multiples of operating performance. The fair value measurements of PEIs are reviewed on a quarterly basis byinterest-only strips. For additional information regarding the Securities Valuation Committee. The Equity Investments Committee, consisting of executives familiar with the investments, reviews periodic financial information, including audited financial statements when available.
Certain valuation analytics may be employed that include current and projected financial performance, recent financing activities, economic and market conditions, market comparables, market liquidity, sales restrictions, and other factors. A significant change in the expected performance of the individual investment would result in a change in the fair value measurement of the investment. The amount of unfunded commitments to invest is

Agriculture Loan Servicing
This asset results from our servicing of agriculture loans approved and funded by Federal Agricultural Mortgage Corporation (“FAMC”). We provide this servicing under an agreement with FAMC for loans they own. The asset’s fair value represents our projection of the present value of future cash flowsinstruments measured under Level 3, using discounted cash flow methodologies.
Interest-Only Strips
Interest-only strips are created as a by-product ofand the securitization process. When the guaranteed portions of Small Business Administration (“SBA”) 7(a) loans are pooled, interest-only strips may be created in the pooling process. The asset’smethods and significant assumptions used to estimate their fair value, representssee Note 3 of our projection2019 Annual Report on Form 10-K.

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$8 million at Septemberboth June 30, 20172020 and $13 million at December 31, 2016.2019. Amounts of other noninterest-bearing investments carried at cost were $324$107 million at SeptemberJune 30, 20172020 and $211$157 million at December 31, 2016,2019, which were comprised of Federal Reserve and Federal Home Loan Bank (“FHLB”) stock. Private equity investments accounted for using the equity method were $35$47 million at SeptemberJune 30, 20172020 and $38$45 million at December 31, 2016.2019.
Impaired (or nonperforming) loansLoans that are collateral dependentcollateral-dependent were measured at fair value based onthe lower of amortized cost or 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 203 of our 20162019 Annual Report on Form 10-K.

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 are reported 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 carrying values of our securities do not include accrued interest receivables of $54 million and $58 million at June 30, 2020 and December 31, 2019, respectively. These receivables are presented in the Consolidated Balance Sheet within the Other Assets line item.
The purchase premiums for callable debt securities classified as HTM or AFS are amortized at an effective yield to the earliest call date. The purchase premiums and discounts for bothall other HTM and AFS securities are amortized and accreted at a constant recognized in interest income over the contractual life of the security using theeffective yield to the contractual maturity date and no assumption is made concerning prepayments.method. As principal prepayments occur,repayments are received on securities, a proportionate amount of the related premium or discount is recognized in income so that the effective yield on the remaining portion of the unamortized premium or discount associated with the principal reduction is recognized as interest

Other-Than-Temporary Impairment
Ongoing Policy
We review investment securities on a quarterly basis for the presence of other-than-temporaryimpairment. For AFS securities, we assess whether impairment (“OTTI”)is present on an individual security basis when the fair value of a debt security is less than its amortized cost basis at the balance sheet date. When determining if the fair value of an investment is less than the amortized cost basis we have elected to exclude accrued interest from the amortized cost basis of the investment. If we have an intent to sell an identified security, or it is more likely than not we will be required to sell the security before recovery of its amortized cost basis, then we recognize an impairment equal to any existing allowance written off against the security.
If we do not have the intent to sell a security, and it is more likely than not that we will not be required to sell a security prior to recovery of its amortized cost basis, then we determine whether there is any impairment attributable to credit-related factors. We analyze certain factors, primarily internal and external credit ratings, to determine if the decline in fair value below the amortized cost basis has resulted from a credit loss or other factors. If a credit impairment is determined to exist, then we measure the amount of credit loss and recognize an allowance for the credit loss. In measuring the credit loss, we generally compare the present value of cash flows expected to be collected from the security to the amortized cost basis of the security. These cash flows are credit adjusted using, among other things, assumptions for default probability and loss severity. Certain other unobservable inputs such as prepayment rate assumptions are also utilized. In addition, certain internal models may be utilized. To determine the credit-related portion of impairment we use the security-specific effective interest rate when estimating the present value of cash flows. If the present value of cash flows is less than the amortized cost basis of the security, then this amount is recorded as an allowance for credit loss, limited to the amount that the fair value is less than the amortized cost basis (i.e., the credit impairment cannot result in the security being carried at an amount lower than its fair value). The assumptions used to estimate the expected cash flows depends on the particular asset class, structure and credit rating of the security. Declines in fair value that are not recorded in the allowance are recorded in other comprehensive income, net of applicable taxes.
AFS Impairment Conclusions
The Bank did not recognize any impairment on its AFS investment securities portfolio during the first six months of 2020. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At SeptemberJune 30, 2017,2020, we had not initiated any sales of AFS securities nor did notwe have an intent to sell any identified securities with unrealized losses, or initiate such sales, and we do not believe it is not more likely than not we would be required to sell such securities before recovery of their amortized cost basis. Therefore, these securities did not have any OTTI recognized during the third quarter of 2017. For additional information on our policy and evaluation process relating to OTTI, see Note 5 of our 2016 Annual Report on Form 10-K.

HTM Credit Quality
For HTM securities, the allowance for credit losses ("ACL") is assessed consistent with the approach discussed in Note 6 for loans carried at amortized cost. The ACL on HTM securities was less than $1 million at June 30, 2020. All HTM securities were risk-graded as "pass" in terms of credit quality and none were past due as of June 30, 2020. The amortized cost basis of HTM securities categorized by year of issuance is summarized as follows:

Effect of Volcker Rule


The Company’s PEIs are subject to the provisions of the Dodd-Frank Act. The Volcker Rule of the Dodd-Frank Act prohibits banks and bank holding companies from holding PEIs, except for SBIC funds and certain other permitted exclusions, beyond a required deadline. The Federal Reserve Board announced in December 2016 that it would allow banks to apply for an additional five-year extension beyond the July 21, 2017 deadline to comply with the Dodd-Frank Act requirement for these investments. The Company applied for and was granted an extension for its eligible PEIs. All positions in the remaining portfolio of PEIs are subject to the extended deadline or other applicable exclusions.
Of the recorded PEIs of $138 million at September 30, 2017, approximately $4 million remain prohibited by the Volcker Rule. At September 30, 2017, we have $27 million of unfunded commitments for PEIs, of which approximately $4 million relate to prohibited PEIs. We currently do not believe that this divestiture requirement will ultimately have a material impact on our financial statements. See other discussions related to private equity investments in Note 3.

Allowance for Credit Losses
The ACLallowance for credit losses (“ACL”), which consists of the allowance for loan and lease losses (“ALLL”("ALLL") and the reserve for unfunded lending commitments, (“RULC”). The ALLL represents our estimate of probable and estimablecurrent expected credit losses inherent inover the contractual term of the loan and lease portfolio and unfunded lending commitments as of the balance sheet date. The ACL for AFS and HTM debt securities is estimated separately from loans. For HTM securities, the ACL is assessed consistent with the approach for loans carried at amortized cost. See Note 5 for further discussion on our assessment of expected credit losses on AFS securities and disclosures related to AFS and HTM securities.
We determine our ACL as the best estimate within a range of estimated current expected losses by using the loan’s amortized cost basis (principal balance, net of unamortized premiums, discounts, and deferred fees and costs). We do not estimate the ACL for accrued interest receivables because we reverse or write-off uncollectible accrued interest receivable balances in a timely manner, generally within one month.
The methodologies we use to estimate the ACL depend upon the type of loan, the age and contractual term of the loan, expected payments (both contractual and assumed prepayments), credit quality indicators, economic forecasts, and the evaluation method (whether individually or collectively evaluated). Expected loan extensions, renewals, or modifications are not considered in the ACL, unless they are included in the original or modified contract at the reporting date and are not unconditionally cancellable, or we reasonably expect them to result in a TDR.
Losses are charged to the ACL when recognized. Generally, commercial and commercial real estate (“CRE”) loans are charged off or charged down when they are determined to be uncollectible in whole or in part, or when 180 days past due, unless the loan is well-secured and in process of collection. Consumer loans are either charged off or charged down to net realizable value no later than the month in which they become 180 days past due. Closed-end consumer loans that are not secured by residential real estate are either charged off or charged down to net realizable value no later than the month in which they become 120 days past due.
We establish the amount of the ACL by analyzing the portfolio at least quarterly, and we adjust the provision for loan losses and unfunded lending commitments to ensure the ACL is at an appropriate level at the balance sheet date.
For commercial and CRE loans with commitments greater than $1 million, we assign internal risk grades using a comprehensive loan grading system based on financial and statistical models, individual credit analysis, and loan officer experience and judgment. The credit quality indicators discussed subsequently are based on this grading system. Estimated credit losses on all loan segments, including consumer and small commercial and CRE loans with commitments less than or equal to $1 million that are evaluated on a collective basis, are derived from statistical analyses of our historical default and loss experience since January 2008.
We estimate current expected credit losses over the contractual remaining life of each loan, which considers historical credit loss experience, current conditions, and reasonable and supportable forecasts about the future. We use the following two types of credit loss estimation models:
Econometric loss models, which rely on statistical analyses of our historical loss experience dependent upon economic factors and other loan-level characteristics. Statistically relevant economic factors vary depending upon the type of loan, but include variables such as unemployment, real estate price indices, energy prices, GDP, etc.
Loss models that are based on our long-term average historical credit loss experience since 2008, which rely on statistical analyses of our historical loss experience dependent upon loan-level characteristics.
61


Table of Contents
ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES
Estimated credit losses during the first 12 months of a loan’s contractual remaining life, or reasonable and supportable period, are derived from the econometric loss models. Over a subsequent 12-month reversion period, we blend the estimated credit losses from the two models on a straight-line basis. For the remaining life of the loan, the estimated credit losses are derived from the long-term average historical credit loss models.
For loans that do not share risk characteristics with other loans, we estimate lifetime expected credit losses on an individual basis. We consider individually-evaluated loans to be nonaccrual loans with a balance greater than $1 million; TDR loans, including TDRs that subsequently default; a loan no longer reported as a TDR; or a loan where we reasonably expect it to become a TDR. When a loan is individually-evaluated for expected credit losses, we estimate a specific reserve for the loan based on the projected present value of the loan’s future cash flows discounted at the loan’s effective interest rate, or the observable market price of the loan, or the fair value of the loan’s underlying collateral.
The process of estimating future cash flows also incorporates the same determining factors discussed subsequently under nonaccrual loans. When we base the specific reserve on the fair value of the loan’s underlying collateral, we generally charge off the portion of the balance that is greater than fair value. For these loans, subsequent to the charge-off, if the fair value of the loan's underlying collateral increases according to an updated appraisal, we hold a negative reserve up to the lesser of the amount of the charge-off or the updated fair value.
The methodologies described above generally rely on historical loss information to help determine our quantitative portion of the ACL. However, we also consider other qualitative and environmental factors related to current conditions and reasonable and supportable forecasts that may indicate current expected credit losses may differ from the historical information reflected in our quantitative models. Thus, after applying historical loss experience, as described above, we review the quantitative portion of ACL for each segment using qualitative criteria, and we use those criteria to determine our qualitative estimate. We monitor various risk factors that influence our judgment regarding the level of the ACL across the portfolio segments. These factors primarily include:
Actual and expected changes in international, national, regional, and local economic and business conditions and developments;
The volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans;
Lending policies and procedures, including changes in underwriting standards and practices for collection, charge-off, and recovery;
The experience, ability, and depth of lending management and other relevant staff;
The nature and volume of the portfolio;
The quality of the credit review function;
The existence, growth, and effect of any concentration of credit;
The effect of other external factors such as regulatory, legal, and technological environments; competition; and events such as natural disasters and pandemics.
The magnitude of the impact of these factors on our qualitative assessment of the ACL changes from quarter to quarter according to changes made by management in its assessment of these factors, the extent these factors are already reflected in quantitative loss estimates, and the extent changes in these factors diverge from one to another. We also consider the uncertainty and imprecision inherent in the estimation process when evaluating the ACL.
Off-Balance-Sheet Credit Exposures
As previously discussed, we estimate a reservecurrent expected credit losses for potential losses associated with off-balance sheetoff-balance-sheet loan commitments, including standby letters of credit. We determine the RULC usingcredit, that are not unconditionally cancellable. This estimate uses the same procedures and methodologies thatdescribed previously for loans and is calculated by taking the difference between the estimated current expected credit loss and the funded balance, if greater than zero.

Changes in the Allowance for Credit Losses
On January 1, 2020, we use foradopted Accounting Standards Update (“ASU”) 2016-13, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and its subsequent updates, often referred to as the ALLL.
For additional information regarding our policies and methodologies usedCurrent Expected Credit Loss ("CECL") standard. Due to estimatethe adoption of the standard, the ACL methodology explained above has significantly changed from the prior period. For more information on our previous ACL methodology, see Note 6 ofin our 20162019 Annual Report on Form 10-K.
The ACL was $914 million at June 30, 2020, compared with $777 million at March 31, 2020. During the second quarter of 2020, our estimate of current expected credit losses increased primarily due to the ongoing economic impact related to the effects of the COVID-19 pandemic.

Nonaccrual and Past Due Loans
Loans are generally placed on nonaccrual status when payment in full of principal and interest is not expected, or the loan is 90 days or more past due as to principal or interest, unless the loan is both well securedwell-secured and in the process of collection. For further discussionFactors we consider in determining whether a loan is placed on nonaccrual include delinquency status, collateral value, borrower or guarantor financial statement information, bankruptcy status, and other information which would indicate that the full and timely collection of our policiesinterest and processes regardingprincipal is uncertain.
A nonaccrual loan may be returned to accrual status when all delinquent interest and past due loans, see Note 6principal become current in accordance with the terms of our 2016 Annual Report on Form 10-K.the loan agreement; the loan, if secured, is well-secured; the borrower has paid according to the contractual terms for a minimum of six months; and an analysis of the borrower indicates a reasonable assurance of the ability and willingness to maintain payments.

Past Due Loans
Closed-end loans with payments scheduled monthly are reported as past due when the borrower is in arrears for two or more monthly payments. Similarly, open-end credits, such as charge-card plans and other revolving credit plans, are reported as past due when the minimum payment has not been made for two or more billing cycles. Other multi-payment obligations (i.e., quarterly, semi-annual, etc.), single payment, and demand notes, are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more.

Credit Quality Indicators
In addition to the nonaccrual and 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, Substandard, and Doubtful, which are consistent with published definitions of regulatory risk classifications. For further discussion
Definitions of our policiesPass, Special Mention, Substandard, and processes regarding credit quality indicators and internal loan risk grading, see Note 6 of our 2016 Annual Report on Form 10-K.
Outstanding loan balances (accruing and nonaccruing) categorized by these credit quality classificationsDoubtful are summarized as follows:
Pass – A Pass asset is higher-quality and does not fit any of the other categories described below. The likelihood of loss is considered low.

Special Mention – A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Bank’s credit position at some future date.
Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have well-defined weaknesses and are characterized by the distinct possibility that the Bank may sustain some loss if deficiencies are not corrected.
Doubtful – A Doubtful asset has all the weaknesses inherent in a Substandard asset with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable.
The balance of loans classified as Doubtful as of June 30, 2020 and December 31, 2019 was insignificant.
We generally assign internal risk grades to commercial and CRE loans with commitments greater than $1 million based on financial and statistical models, individual credit analysis, and loan officer experience and judgment. For these larger loans, we assign one of multiple grades within the Pass classification or one of the following four grades: Special Mention, Substandard, Doubtful, and Loss. Loss indicates that the outstanding balance has been charged off. We confirm our internal risk grades quarterly, or as soon as we identify information that affects the credit risk of the loan.
For consumer loans and certain small commercial and CRE loans with commitments less than or equal to $1 million, we generally assign internal risk grades similar to those described previously based on automated rules that depend on refreshed credit scores, payment performance, and other risk indicators. These are generally assigned either a Pass or Substandard grade and are reviewed as we identify information that might warrant a grade change.

Impaired Loans
LoansThe amortized cost basis of loans and leases categorized by year of origination and by credit quality classifications as monitored by management 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 income recognized on a cash basis during the time the loans were impaired within the three and six months ended September 30, 2017 and 2016 was not significant. For additional information regarding our policies and methodologies used to evaluate impaired loans, see Note 6 of our 2016 Annual Report on Form 10-K.
Information on impaired loans individually evaluated is summarized as follows, including the average recorded investment and interest income recognized for the three months ended September 30, 2017 and 2016:follows:

Modified and Restructured Loans
Loans may be modified in the normal course of business for competitive reasons or to strengthen the Company’sBank’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 CompanyBank has granted a concession that it would not otherwise consider, are considered troubled debt restructurings (“TDRs”).
Consistent with recent accounting and regulatory guidance, loan modifications provided to borrowers experiencing financial difficulties exclusively related to the COVID-19 pandemic, in which we provide certain short-term modifications or payment deferrals, are not classified as TDRs. The TDRs disclosed subsequently do not include these loan modifications.
For further discussion of our policies and processes regarding TDRs, see Note 6 of our 20162019 Annual Report on Form 10-K.

Unfunded lending commitments on TDRs amounted to approximately $18$4 million and $5 million at SeptemberJune 30, 20172020 and $14 million at December 31, 2016.2019, respectively.
The total recorded investment of all TDRs in which interest rates were modified below market was $116$77 million at SeptemberJune 30, 20172020 and $128$73 million at December 31, 2016.2019. 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 and ninesix months ended SeptemberJune 30, 20172020 and 20162019 was not significant.

ZIONS BANCORPORATION AND SUBSIDIARIES

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.

Collateral-Dependent Loans
As discussed previously, when a loan is individually-evaluated for expected credit losses, we estimate a specific reserve for the loan based on the projected present value of the loan’s future cash flows discounted at the loan’s effective interest rate, or the observable market price of the loan, or the fair value of the loan’s underlying collateral.
Selected information on loans for which the repayment is expected to be provided substantially through the operation or sale of the underlying collateral and the borrower is experiencing financial difficulties, including the type of collateral and the extent to which the collateral secures the loans, is summarized as follows:

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 20162019 Annual Report on Form 10-K for further discussion of our evaluation of credit risk concentrations. See also Note 7 of our 20162019 Annual Report on Form 10-K for a discussion of counterparty risk associated with the Company’sBank’s derivative transactions.
Purchased Loans
Background and Accounting
We purchase loans in the ordinary course of business and account for them and the related interest income based on their performing status at the time of acquisition. Purchased credit-impaired (“PCI”) loans have evidence of credit deterioration at the time of acquisition and it is probable that not all contractual payments will be collected. Interest income for PCI loans is accounted for on an expected cash flow basis. Upon acquisition, in accordance with applicable accounting guidance, the acquired loans were recorded at their fair value without a corresponding ALLL. Certain acquired loans with similar characteristics such as risk exposure, type, size, etc., are grouped and accounted for in loan pools.

At the time of acquisition of PCI loans, we determine the loan’s contractually required payments in excess of all cash flows expected to be collected as an amount that should not be accreted (nonaccretable difference). With respect to the cash flows expected to be collected, the portion representing the excess of the loan’s expected cash flows over our initial investment (accretable yield) is accreted into interest income on a level yield basis over the remaining expected life of the loan or pool of loans. The effects of estimated prepayments are considered in estimating the expected cash flows.
Certain PCI loans are not accounted for as previously described because the estimation of cash flows to be collected involves a high degree of uncertainty. Under these circumstances, the accounting guidance provides that interest income is recognized on a cash basis similar to the cost recovery methodology for nonaccrual loans. The net carrying amounts in the preceding schedule also include the amounts for these loans. There were no loans of this type at September 30, 2017 and December 31, 2016.

Note: Amounts have been adjusted based on refinements to the original estimates of the accretable yield.
The primary drivers of reclassification to accretable yield from nonaccretable difference and increases in disposals and other resulted primarily from (1) changes in estimated cash flows, (2) unexpected payments on nonaccrual loans, and (3) recoveries on zero balance loans pools. See subsequent discussion under changes in cash flow estimates.
ALLL Determination
For all acquired loans, the ALLL is only established for credit deterioration subsequent to the date of acquisition and represents our estimate of the inherent losses in excess of the book value of acquired loans. The ALLL for acquired loans is included in the overall ALLL in the balance sheet.
During the three and nine months ended September 30, we adjusted the ALLL for acquired loans by recording a provision for loan losses of an insignificant amount for both periods in 2017, and $1 million and $2 million in 2016, respectively. The provision is net of the ALLL reversals resulting from changes in cash flow estimates, which are discussed subsequently.

ZIONS BANCORPORATION AND SUBSIDIARIES

Changes in the provision for loan losses and related ALLL are driven in large part by the same factors that affect the changes in reclassification from nonaccretable difference to accretable yield, as discussed under changes in cash flow estimates.
Changes in Cash Flow Estimates
Over the life of the loan or loan pool, we continue to estimate cash flows expected to be collected. We evaluate quarterly at the balance sheet date whether the estimated present values of these loans using the effective interest rates have decreased below their carrying values. If so, we record a provision for loan losses.
For increases in carrying values that resulted from better-than-expected cash flows, we use such increases first to reverse any existing ALLL. During the three and nine months endedSeptember 30, total reversals to the ALLL, including the impact of increases in estimated cash flows, were insignificant during both periods in 2017 and $1 million during both periods in 2016, respectively. When there is no current ALLL, we increase the amount of accretable yield on a prospective basis over the remaining life of the loan and recognize this increase in interest income.
For the three and nine months ended September 30, the impact of increased cash flow estimates recognized in the statement of income for acquired loans with no ALLL was approximately $2 million and $15 million in 2017, and $4 million and $14 million in 2016, respectively, of additional interest income.
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 20162019 Annual Report on Form 10-K10-K.
Fair Value Hedges – As of June 30, 2020, the Bank had $500 million notional amount of an interest rate swap designated in a qualifying fair value hedge relationship. The hedging instrument used is a receive-fixed interest rate swap converting the interest on our fixed-rate debt to floating. The hedge is designated as a fair value hedge of the change in fair value of the London Interbank Offered Rate (“LIBOR”) benchmark swap rate component of the contractual coupon cash flows of our fixed-rate debt. The swap is structured to match the critical terms of the hedged notes, resulting in the expectation that the swap will be highly effective as a hedging instrument. All interest rate swaps designated as fair value hedges were highly effective and met all other requirements to remain designated and part of qualifying hedge accounting relationships as of the balance sheet date. During the second quarter of 2020, the fair value hedge swap portfolio increased in value by $4 million, which was offset by the change in fair value of the hedged debt, resulting in no direct earnings impact.
At December 31, 2019 we had $1.5 billion of fixed-to-floating interest rate swaps designated as fair value hedges of long-term debt (effectively converting the fixed-rate debt into floating-rate debt). In late March 2020, we terminated $1 billion of swaps (i.e., 2 $500 million swaps with maturities in August 2021 and February 2022) with a combined fair value of $36 million. As a result, the cumulative basis adjustment on the debt at the time of the terminations will be amortized as an adjustment to interest expense through the maturity of the debt, thereby reducing the effective interest rate. During the second quarter of 2020, the Bank amortized $7 million of the outstanding unamortized debt basis adjustment. Additionally, as part of the repurchase and retirement of senior notes, the Bank recognized $12 million of the unamortized debt basis adjustment in Other noninterest expense. As of June 30, 2020, the Bank has $18 million of unamortized debt basis adjustments from previously designed fair value hedges remaining.
Cash Flow Hedges – For derivatives designated as qualifying cash flow hedges, periodic changes in fair value are deferred in AOCI. Amounts deferred in AOCI are reclassified into earnings in the periods in which the hedged forecasted transactions (i.e., the hedged floating-rate commercial loan interest receipts) are recognized in earnings or become probable not to occur.
As of June 30, 2020, the Bank had $3.5 billion notional amount of receive-fixed interest rate swaps designated as cash flow hedges of pools of floating-rate commercial loans. During the second quarter of 2020, the Bank's cash flow hedge portfolio decreased in value by $4 million, which was recorded in AOCI. The amounts deferred in AOCI are reclassified into earnings in the periods in which the interest payments occur (i.e. when the hedged forecasted transactions affect 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 20162019 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 under their contracts.by the contractual terms. At SeptemberJune 30, 2017,2020, the fair value of our derivative liabilities was $35$502 million, for which we were required to pledge cash collateral of approximately $46$81 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 SeptemberJune 30, 2017, the2020, there would likely be $3 million of additional amount of collateral we could be required to pledge is approximately $1 million.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.

We determine if a contract is a lease or contains a lease at inception. For a more detailed discussion of our lease policies, see Note 8 of our 2019 Annual Report on Form 10-K.
We have operating and finance leases for branches, corporate offices, and data centers. Our equipment leases are not material. At June 30, 2020, we had 421 branches, of which 274 are owned and 147 are leased. We lease our headquarters in Salt Lake City, Utah, and other office or data centers are either owned or leased.
The fair valueBank may enter into certain lease arrangements with a term of derivative12 months or less, and we have elected to exclude these from capitalization. The length of our commitments for leases ranges from 2020 to 2062, some of which include options to extend or terminate the leases.
Assets recorded under operating leases were $209 million at June 30, 2020, and $218 million at December 31, 2019, while assets was reduced by a net credit valuation adjustment ofrecorded under finance leases were $4 million at both of those dates. 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 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 $3 million for both the second quarters of 2020 and 2019, and $6 million for both the first six months of 2020 and 2019.
The Bank also has a lending division that makes equipment leases, considered to be sales-type leases or direct financing leases, totaling $324 million and $334 million as of June 30, 2020 and December 31, 2019, respectively. The Bank uses leasing of equipment as a venue for customers to access equipment without purchasing upfront. The Bank recorded income of $3 million on these leases for both the second quarters of 2020 and 2019, and $7 million at September 30, 2017for both the first six months of 2020 and 2016, respectively.

The change in outstanding senior and subordinated debt balances from December 31, 2019 to June 30, 2020 was primarily a result of the repurchase and retirement of senior notes that had adjustments to their carrying values from being in designated hedge relationships with interest rate swaps.

The Company’s 2016Bank’s 2019 Annual Report on Form 10-K contains further information about these commitments and guarantees including their terms and collateral requirements. At SeptemberJune 30, 2017,2020, the CompanyBank had recorded approximately $5$6 million as a liability for the guarantees associated with the standby letters of credit, which consisted of $1$4 million attributable to the RULC and $4$2 million of deferred commitment fees.

PEIs related to these commitments that are prohibited by the Volcker Rule were $4 million at September 30, 2017. See related discussions about these investments in Notes 3 and 5.
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 SeptemberJune 30, 2017,2020, we were subject to the following material litigation andor 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. This case is in an early phase, with initial motion practice having been completed.
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. This case is in an early phase with initial motion practice having been completed.
a civil suit, JTS Communities, Inc. et. al v. CB&T, Jun Enkoji and Dawn Satow, brought against us in the Superior Court of California,for Sacramento County, California in June 2017. In this case four investors in IMGour former customer, International Manufacturing Group (“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.scheme. This case is in the discovery phase with dispositive motion practice underway. The hearings for the dispositive motions have been delayed, and the previously scheduled May 2020 trial setting has been vacated to be reset in the future due to the COVID-19 pandemic.

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 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.
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 with the Court of Appeals reversing the trial court’s dismissal. This case is in the post-pleading phase and trial will not occur for a substantial period of time.
Attwo civil cases, Lifescan Inc. and Johnson & Johnson Health Care Services v. Jeffrey Smith, et. al., brought against us in the endUnited States District Court for the District of SeptemberNew 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 who filed for bankruptcy protection in 2017. The cases are in early phases, with initial motion practice and discovery underway in the Lifescan case. Trial has not been scheduled in either case.
a civil class action lawsuit, Gregory, et. al. v. Zions Bancorporation, brought against us in the United States District Court for Utah in January 2019. This case was filed on behalf of investors in Rust Rare Coin, Inc., alleging that we settledaided and abetted a governmental inquiry conductedPonzi scheme fraud perpetrated by Rust Rare Coin, a Zions Bank customer. The case follows 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 U.S. Attorney’s OfficeSEC against Rust Rare Coin and its principal, Gaylen Rust. The matter is in the early motion practice state. During the second quarter of 2019, we filed a motion to dismiss which has not yet been ruled upon by the Court. Trial has not been scheduled.
two civil class action lawsuits, Fahmia Inc.v. Zions Bancorporation, et. al., brought against us in the United States District Court for the Eastern District of Pennsylvania into our payment processing practices relating to certain telemarketing customers alleged to have engagedColorado in fraudulent marketing practices, primarilyJune 2020, and ImpAcct LLC v. JPMorgan Chase, et. al., brought against us and other banks in the 2006-2008 timeframe. The settlement agreement imposed a civil money penaltyUnited States District Court for the Central District of $3.6 million, whichCalifornia in June 2020. A third class action lawsuit, Manoloff v. Bank of America, et. al., was paidfiled against us in the third quarter. Because this amount had been fully reserved,United States District Court for the settlement did not affect our third quarter financial results.Southern District of Texas in July 2020. These cases allege that we wrongly failed to pay agents of borrowers receiving loans from us under the Government's Paycheck Protection Program fees that were allegedly owed to them under the program. These cases are similar to class action lawsuits filed against other banks and will likely involve complicated procedural issues.
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.

ZIONS BANCORPORATION AND SUBSIDIARIES

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 SeptemberJune 30, 2017,2020, we estimated that the aggregate range of reasonably possible losses for those matters to be from $0 millionto roughly $20$35 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
83


ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES
these matters, and the very large or indeterminate damages sought in some of these matters, an adverse outcome in 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 second quarter of 2020. 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 17 of our 2019 Annual Report on Form 10-K.
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 certain non-bank financial services subsidiaries, centralized back-office functions, and eliminations of transactions between 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.
The following schedule presents the noninterest income and net revenue by operating segments for the three months ended June 30, 2020 and 2019:

The effective income tax rate of 34.2%19.5% for the thirdsecond quarter of 20172020 was slightly higherlower than the 2016 third2019 second quarter rate of 33.9%22.7%. The effective tax rates for the first ninesix months of 20172020 and 20162019 were 30.6%18.4% and 33.3%22.5%, respectively. TheseThe income tax rates for both 20172020 and 2016 generally benefited2019 were reduced by nontaxable municipal interest income and nontaxable income from the non-taxability of certain income items. The 2017 effective tax rate was further impactedbank-owned life insurance, and were increased by the following factors:
We re-evaluated our statenon-deductibility of Federal Deposit Insurance Corporation (“FDIC”) premiums, certain executive compensation, and other fringe benefits. Further, the 2020 tax positionsrates were reduced as a result of the proportional increases in nontaxable items and tax credits relative to pretax book income as compared with the first quarter of 2017, which resulted in a one-time $14 million benefit to income tax expense.
We reduced income tax expense by $4 million in the second quarter of 2017 due to changes in the carrying value of various state deferred tax items.
We also recorded an $8 million benefit in the first nine months of 2017 from the implementation of new accounting guidance related to stock-based compensation.prior year periods.
We had a net deferred tax asset (“DTA”) balance of $207$22 million at SeptemberJune 30, 2017,2020, compared with $250$37 million at December 31, 2016, which included a $4 million valuation allowance at each respective reporting date2019. The decrease in the net DTA resulted primarily from the decrease of accrued compensation and an increase in unrealized gains in other comprehensive income ("OCI") related to securities. An increase in the provision for certain acquiredloan losses in excess of net operating loss carryforwardscharge-offs, 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 continuesis continually refined. In the third quarter of 2019, we made changes to be refined.the FTP process to more accurately reflect the cost of funds for loans. Prior period amounts have been revised to reflect the impact of these changes had they been instituted for the periods presented. Total average loans and deposits presented for the banking segments do not include insignificant intercompany amounts between banking segments butand may also include deposits with the Other segment. Prior period amounts have been reclassified to reflect these changes.
As of SeptemberJune 30, 2017,2020, our banking business is conducted through 7 locally managed and branded segments in distinct geographical areas. Zions Bank operates 9895 branches in Utah, 2325 branches in Idaho, and one1 branch in Wyoming. Amegy operates 7375 branches in Texas. CB&T operates 9285 branches in California. NBAZ operates 5856 branches in Arizona. NSB operates 5046 branches in Nevada. Vectra operates 3634 branches in Colorado and one1 branch in New Mexico. TCBW operates one branch2 branches in Washington and one1 branch in Oregon.
The operating segment identified as “Other” includes the Parent, Zions Management Services Company, certain nonbanknon-bank 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 officeback-office include the revenue associated with the investments securities portfolio and the offset of the FTP costs and benefits provided to the business segments. Throughout 2016 consolidation efforts continued, which resulted in transitioning full-time equivalents from the business segments to the Company’s back-office units. Due to the continuing nature and timing of this change, the Company’s back-office units retained more direct expenses in 2016 than in prior years. In the first quarter of 2017 we made changes to the FTP process and internal allocation of central expenses to better reflect the performance of business segments. Prior period amounts have been revised to reflect the impact of these changes had they been instituted in 2016.
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 Parent’s net interest income includes interest expense on other 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 Company.Bank. Transactions between operating segments are primarily conducted at fair value, resulting in profits that are eliminated for reporting consolidated results of operations.

We believe there have been no material changes inIn addition to the risk factors included in Zions Bancorporation’s 2016Bancorporation, National Association’s 2019 Annual Report on Form 10-K.10-K, we have added the following risk factor:
Our business, financial condition, liquidity and results of operations have been, and will likely continue to be, adversely affected by the COVID-19 pandemic.
The COVID-19 pandemic has created economic and financial disruptions that have adversely affected, and are likely to continue to adversely affect, our business, financial condition, liquidity, capital and results of operations. The extent to which the COVID-19 pandemic will continue to negatively affect our business, financial condition, liquidity and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic, the continued effectiveness of our business continuity plan, the direct and indirect impact of the pandemic on our employees, customers, communities, counterparties and service providers, as well as other market participants, and actions taken by governmental authorities and other third parties in response to the pandemic.
The COVID-19 pandemic has contributed to the following, any of which could have an adverse effect on our business, financial condition, liquidity and results of operations:

ITEM 2.UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
ZIONS BANCORPORATION, NATIONAL ASSOCIATION AND SUBSIDIARIES
Increased unemployment and decreased consumer confidence and business generally, leading to an increased risk of delinquencies, defaults and foreclosures.
Ratings downgrades, credit deterioration and defaults in many sectors and industries, including, but not limited to, states and municipalities, retail, oil and gas, hotels and casinos, restaurants, telecommunications/media, real estate/construction, airlines and transportation, leisure and recreation.
A sudden and significant reduction in the valuation of the equity, fixed-income and commodity markets and the significant increase in the volatility of those markets.
A decrease in the rates and yields on U.S. Treasury and other securities, which may lead to decreased net interest income.
Increased demands on capital and liquidity.
A reduction in the value of the assets that the Bank manages or otherwise administers or services for others, affecting related fee income and demand for the Bank’s services.
Heightened cybersecurity, information security and operational risks as a result of work-from-home arrangements.
We are prioritizing the safety of our customers, communities and employees, and have limited branch activity to be occupied by a specified number of individuals at any given time, drive-through services or in-office appointments. Additionally, the majority of employees are working remotely. If these measures are not effective in serving our customers or affect the productivity of our associates, they may lead to significant disruptions in our business operations.
Many of our counterparties and third-party service providers have also been, and may further be, affected by “stay-at-home” orders, market volatility and other factors that increase their risks of business disruption or that may otherwise affect their ability to perform under the terms of any agreements with us or provide essential services. As a result, our operational and other risks are generally expected to increase until the pandemic subsides.
We are offering special financial assistance to support customers who are experiencing financial hardships related to the COVID-19 pandemic, including waivers of certain withdrawal fees from CDs and savings and money market accounts, loan payment deferrals and extensions, credit card payment extensions, temporary consumer mortgage payment forbearance and payment deferment, suspending initiation of new repossessions of automobiles and other vehicles and suspending new residential property foreclosures on consumer real estate loans. If such measures are not effective in mitigating the effects of the COVID-19 pandemic on borrowers, we may experience higher rates of default and increased credit losses in future periods.
Certain segments and industries where the Bank has credit exposure, including, but not limited to, states and municipalities, retail, oil and gas, hotels and casinos, restaurants, telecommunications/media, real estate/construction, airlines and transportation, leisure and recreation, have experienced significant operational challenges as a result of the COVID-19 pandemic. In some cases, the COVID-19 pandemic accelerated deterioration in industries, such as oil and gas, that were already experiencing increased volatility and stress. These negative effects may result in a number of clients making higher than usual draws on outstanding lines of credit, which may negatively affect our liquidity if current economic conditions persist. These assistance efforts may adversely affect our revenue and results of operations. In addition, the effects of the COVID-19 pandemic may also cause our municipal and commercial customers to be unable to pay their loans as they come due or decrease the value of collateral, which we expect would cause significant increases in our credit losses.
Net interest income is the largest component of the Bank’s revenue. Net interest income is significantly affected by market rates of interest. The significant reductions to the federal funds rate has led to a decrease in the rates and yields on U.S. Treasury securities, in some cases declining below zero. If interest rates are reduced further in response to the COVID-19 pandemic, we expect that our net interest income will decline, perhaps significantly. The overall effect of lower interest rates on the economic environment cannot be predicted at this time and depends on future actions the Federal Reserve may take to increase or reduce the targeted federal funds rate in response to the COVID-19 pandemic, and resulting economic conditions.

Governmental authorities have taken unprecedented measures to provide economic assistance to individual households and businesses, stabilize the markets and support economic growth. The success of these measures is unknown and they may not be sufficient to fully mitigate the negative impact of the COVID-19 pandemic. Additionally, some measures, such as a suspension of mortgage and other loan payments and foreclosures, may have a negative impact on the Bank’s business, financial condition, liquidity and results of operations. We also face an increased risk of litigation and governmental and regulatory scrutiny as a result of the effects of the COVID-19 pandemic on market and economic conditions and actions governmental authorities take in response to those conditions.
The length of the pandemic and the efficacy of the extraordinary measures being put in place to address it are unknown. Until the pandemic subsides, the Bank expects continued draws on lines of credit, reduced revenues and increased customer and client defaults. Even after the pandemic subsides, the U.S. economy may experience a recession which may be prolonged, which could materially and adversely affect the Bank’s business, financial condition, liquidity and capital. To the extent the COVID-19 pandemic adversely affects our business, financial condition, liquidity, capital or results of operations, it may also have the effect of heightening many of the other risks described in the section entitled “Risk Factors” in the Bank’s 2019 Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q.
