The accompanying consolidated financial statements include the accounts of Old National Bancorp and its wholly-owned affiliates (hereinafter collectively referred to as “Old National”) and have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Such principles require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosures of contingent assets and liabilities at the date of the financial statements and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Old National classified all of its debt investment securities as available-for-sale at December 31, 2020. Debt securities classified as available-for-sale are recorded at fair value with the unrealized gains and losses, net of tax effect, recorded in other comprehensive income. Realized gains and losses affect income and the prior fair value adjustments are reclassified within shareholders’ equity. Prior to the fourth quarter of 2019, Old National also had debt securities classified as held-to-maturity. Debt securities classified as held-to-maturity, which management had the intent and ability to hold to maturity, were reported at amortized cost. Interest income included amortization of purchase premiums or discounts. Premiums and discounts were amortized on the level-yield method. Anticipated prepayments were considered when amortizing premiums and discounts on mortgage backed securities. Gains and losses on the sale of available-for-sale debt securities are determined using the specific-identification method.

Available-for-sale debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. For available-for sale debt securities in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For available-for-sale debt securities that do not meet the criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security and the issuer, among other factors. If this assessment indicates that a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of applicable taxes. Accrued interest receivable on available-for-sale debt securities is excluded from the estimate of credit losses.

Loans that Old National has originated with an intent to sell are classified as loans held for sale and are recorded at fair value, determined individually, as of the balance sheet date. The loan’s fair value includes the servicing value of the loans as well as any accrued interest. Conventional mortgage production is sold on a servicing retained basis. Certain loans, such as government guaranteed mortgage loans are sold on servicing released basis. Mortgage loans held for immediate sale in the secondary market were $63.3 million at December 31, 2020, compared to $46.9 million at December 31, 2019.

Loans that Old National intends to hold for investment purposes are classified as portfolio loans. Portfolio loans are carried at the principal balance outstanding, net of earned interest, purchase premiums or discounts, deferred loan fees and costs, and an allowance for credit losses. Interest income is accrued on the principal balances of loans outstanding. For all loan classes, a loan is generally placed on nonaccrual status when principal or interest becomes 90 days past due unless it is well secured and in the process of collection, or earlier when concern exists as to the ultimate collectability of principal or interest. Interest accrued but not received is reversed against earnings. Cash interest received on these loans is applied to the principal balance until the principal is recovered or until the loan returns to accrual status. Loans may be returned to accrual status when all the principal and interest amounts contractually due are brought current, remain current for a prescribed period, and future payments are reasonably assured.

Old National has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and initial allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is accreted or amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision for credit losses.

Credit quality within the loans held for investment portfolio is continuously monitored by management and is reflected within the allowance for credit losses for loans. The allowance for credit losses is an estimate of expected losses inherent within the Company’s loans held for investment portfolio. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and in our process for estimating expected credit losses. Expected credit loss inherent in non-cancelable off-balance-sheet credit exposures is accounted for as a separate liability included in other liabilities on the balance sheet. The allowance for credit losses for loans held for investment is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries. We have made a policy election to report accrued interest receivable as a separate line item on the balance sheet.

The allowance for credit loss estimation process involves procedures to appropriately consider the unique characteristics of the loan portfolio segments. These segments are further disaggregated into loan classes based on the level at which credit risk is monitored. When computing the level of expected credit losses, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods.

The allowance level is influenced by loan volumes, loan AQR migration or delinquency status, changes in historical loss experience, and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses reported in the allowance for credit losses has two basic components: first, an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans; and second, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics.

We utilize a discounted cashflow approach to determine the allowance for credit losses for performing loans and nonperforming loans. Expected cashflows are created for each loan and discounted using the effective yield. The discounted sum of expected cashflows is then compared to the amortized cost and any shortfall is recorded as reserve. Expected cashflows are created using a combination of contractual payment schedules, calculated PDs, LGD, and prepayment assumptions as well as qualitative factors. For the commercial and commercial real estate loans, the PD is forecast using a regression model to determine the likelihood of a loan moving into nonaccrual within the time horizon. For residential and consumer loans, the PD is forecast using a regression model to determine the likelihood of a loan being charged-off within the time horizon. The regression models use combinations of variables to assess systematic and unsystematic risk. Variables used for unsystematic risk are borrower specific and help to gauge the risk of default from an individual borrower. Variables for systematic risk, risk inherent to all borrowers, come from the use of forward-looking economic forecasts and include variables such as unemployment rate, gross domestic product, and house price index. The LGD is defined as credit loss incurred when an obligor of the bank defaults. Qualitative factors include items such as changes in lending policies or procedures and economic uncertainty in forward-looking forecasts.

Premises and equipment are stated at cost less accumulated depreciation. Land is stated at cost. Depreciation is charged to operating expense over the useful lives of the assets, principally on the straight-line method. Useful lives for premises and equipment are as follows: buildings and building improvements – 15 to 39 years; and furniture and equipment – 3 to 7 years. Leasehold improvements are depreciated over the lesser of their useful lives or the term of the lease. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Interest costs on construction of qualifying assets are capitalized.

The excess of the cost of acquired entities over the fair value of identifiable assets acquired less liabilities assumed is recorded as goodwill. Amortization of goodwill and indefinite-lived assets is not recorded. However, the recoverability of goodwill and other intangible assets are tested annually for impairment. Other intangible assets, including core deposits and customer business relationships, are amortized primarily on an accelerated basis over their estimated useful lives, generally over a period of 5 to 15 years.

Loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type, term, and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If Old National later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking revenue on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement as mortgage banking revenue, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal, or a fixed amount per loan and are recorded as income when earned.

As part of Old National’s overall interest rate risk management, Old National uses derivative instruments, including TBA forward agreements and interest rate swaps, collars, caps, and floors. All derivative instruments are recognized on the balance sheet at their fair value. At the inception of the derivative contract, Old National designates the derivative as (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the change in value of the derivative, as well as the offsetting change in value of the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. For a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, in noninterest income.

Old National formally documents all relationships between derivatives and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. Old National also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of the hedged items. Old National discontinues hedge accounting prospectively when it is determined that (1) the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item; (2) the derivative expires, is sold, or terminated; (3) the derivative instrument is de-designated as a hedge because the forecasted transaction is no longer probable of occurring; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management otherwise determines that designation of the derivative as a hedging instrument is no longer appropriate.

When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transaction is still expected to occur, changes in value that were accumulated in other comprehensive income are amortized or accreted into earnings over the same periods which the hedged transactions will affect earnings.

Old National is exposed to losses if a counterparty fails to make its payments under a contract in which Old National is in the net receiving position. Old National anticipates that the counterparties will be able to fully satisfy their obligations under the agreements. In addition, Old National obtains collateral above certain thresholds of the fair value of its hedges for each counterparty based upon their credit standing. All of the contracts to which Old National is a party settle monthly, quarterly, or semiannually. Further, Old National has netting agreements with the dealers with which it does business.

In the ordinary course of business, Old National’s bank subsidiary has entered into credit-related financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit. The notional amount of these commitments is not reflected in the consolidated financial statements until they are funded. Old National maintains an allowance for credit losses on unfunded commercial lending commitments and letters of credit to provide for the risk of loss inherent in these arrangements. The allowance is computed using a methodology similar to that used to determine the allowance for credit losses for loans, modified to take into account the probability of a drawdown on the commitment. The allowance for credit losses on unfunded loan commitments is classified as a liability account on the balance sheet and is adjusted as a provision for credit loss expense included in other expense.

Other real estate owned and repossessed personal property are initially recorded at the fair value of the property less estimated cost to sell and are included in other assets on the balance sheet. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through the completion of a deed in lieu of foreclosure or through a similar legal agreement. Any excess recorded investment over the fair value of the property received is charged to the allowance for credit losses. Any subsequent write-downs are recorded in noninterest expense, as are the costs of operating the properties. Gains or losses resulting from the sale of collateral are recognized in noninterest expense at the date of sale.

We purchase certain securities, generally U.S. government-sponsored entity and agency securities, under agreements to resell. The amounts advanced under these agreements represent short-term secured loans and are reflected as assets in the accompanying consolidated balance sheets. We also sell certain securities under agreements to repurchase. These agreements are treated as collateralized financing transactions. These secured borrowings are reflected as liabilities in the accompanying consolidated balance sheets and are recorded at the amount of cash received in connection with the transaction. Short-term securities sold under agreements to repurchase generally mature within one to four days from the transaction date. Securities, generally U.S. government and federal agency securities, pledged as collateral under these financing arrangements can be repledged by the secured party. Additional collateral may be required based on the fair value of the underlying securities.

Compensation cost is recognized for stock options, stock appreciation rights, and restricted stock awards and units issued to employees based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options and appreciation rights, while the market price of our Common Stock at the date of grant is used for restricted stock awards. A third party provider is used to value certain restricted stock units where the performance measure is based on total shareholder return. Compensation expense is recognized over the required service period. Forfeitures are recognized as they occur.

Old National is a limited partner in several tax-advantaged limited partnerships whose purpose is to invest in approved qualified affordable housing, renewable energy, or other renovation or community revitalization projects. These investments are included in other assets on the balance sheet, with any unfunded commitments included with other liabilities. Certain of these assets qualify for the proportional amortization method and are amortized over the period that Old National expects to receive the tax credits, with the expense included within income tax expense on the consolidated statements of income. The other investments are accounted for under the equity method, with the expense included within noninterest expense on the consolidated statements of income. All of our tax credit investments are evaluated for impairment at the end of each reporting period.

For the purpose of presentation in the accompanying consolidated statement of cash flows, cash and cash equivalents are defined as cash, due from banks, federal funds sold and resell agreements, and money market investments, which have maturities less than 90 days. Cash flows from loans, either originated or acquired, are classified at that time according to management’s intent to either sell or hold the loan for the foreseeable future. When management’s intent is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management’s intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows.

Old National accounts for business combinations using the acquisition method of accounting. The accounts of an acquired entity are included as of the date of acquisition, and any excess of purchase price over the fair value of the net assets acquired is capitalized as goodwill. Old National typically issues Common Stock and/or pays cash for an acquisition, depending on the terms of the acquisition agreement. The value of Common Stock issued is determined based on the market price of the stock as of the closing of the acquisition. Acquisition costs are expensed when incurred.

FASB ASC 326 – In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and all related subsequent amendments thereto (“ASC 326” or “Topic 326”). The main objective of this amendment is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments within its scope, including loans held for investment purposes and other commitments to extend credit held by a reporting entity at each reporting date. The amendment requires the measurement of all expected credit losses for the in-scope financial assets at the date of origination or acquisition, and at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to enhance their credit loss estimates. The amendment requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The current expected credit loss measurement will be used to estimate the allowance for credit losses over the life of the financial assets. The amendments in this update became effective for annual periods and interim periods within those annual periods beginning after December 15, 2019.

As previously disclosed, Old National formed a cross-functional committee to oversee the adoption of the ASU at the effective date. A working group was also formed to develop a project plan focused on understanding the ASU, researching issues, identifying data needs for modeling inputs, technology requirements, modeling considerations, and ensuring overarching governance was achieved for each objective and milestone. The working group identified seven distinct loan portfolios for which a model to estimate credit losses has been developed. For all seven loan portfolios, the data sets have been identified, populated, and internally validated. Old National has completed data and model validation testing. During the last half of 2019, the project plan targeted parallel processing of our existing allowance for loan losses model compared to the CECL model, as well as model sensitivity analysis, determination of qualitative adjustments, supporting analytics, and execution of the governance and approval process. Internal controls related to the CECL process were finalized prior to adoption on January 1, 2020.

Old National adopted CECL on January 1, 2020 using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Results for the reporting periods after January 1, 2020 are presented under Topic 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. As of that date, Old National increased the allowance for credit losses for loans by $41.3 million and increased the allowance for credit losses for unfunded loan commitments by $4.5 million, since the ASU covers credit losses over the expected life of a loan as well as considering future changes in macroeconomic conditions. The increase related to the acquired loan portfolio totaled $27.1 million. Under the

previously applicable accounting guidance, any remaining unamortized loan discount on an individual loan could be used to offset a charge-off for that loan, so the allowance for loan losses needed for the acquired loans was reduced by the remaining loan discounts. ASU 2016-13 requires an allowance for credit losses to be recognized in addition to the loan discount. The impact of adopting the ASU, and at each subsequent reporting period, is highly dependent on credit quality, macroeconomic forecasts and conditions, composition of our loans and available-for-sale securities portfolio, along with other management judgements. As of January 1, 2020, Old National recorded a cumulative-effect adjustment of $31.2 million to decrease retained earnings.

We adopted CECL using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as purchased credit impaired and accounted for under ASC 310-30. In accordance with the standard, we did not reassess whether PCI assets met the definition of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $4.5 million to the allowance for credit losses for loans. The remaining noncredit discount in the amount of $11.8 million (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2020.

The loan categories used to monitor and analyze interest income and yields are different than the portfolio segments used to determine the allowance for credit losses for loans. The allowance for credit losses was calculated by pooling loans of similar credit risk characteristics and credit monitoring procedures. The four loan portfolios are classified into seven segments of loans - commercial, commercial real estate, BBCC, residential real estate, indirect, direct, and home equity. The commercial and commercial real estate loan categories shown on the balance sheet include the same pool of loans as the commercial, commercial real estate, and BBCC portfolio segments. The consumer loan category shown on the balance sheet is comprised of the same loans in the indirect, direct, and home equity portfolio segments. The composition of loans by portfolio segment as of December 31, 2019 follows:

In December 2018, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ implementation of CECL. The final rule provides banking organizations the option to phase in over a three-year period the day-one adverse effects on regulatory capital that may result from the adoption of the new accounting standard. In March 2020, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC published an interim final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. The interim final rule maintains the three-year transition option in the previous rule and provides banks the option to delay for two years an estimate of CECL’s effect on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period (five-year transition option). Old National is adopting the capital transition relief over the permissible five-year period.

FASB ASC 350 – In January 2017, the FASB issued ASU No. 2017-04, Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the amendments eliminate Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, the income tax effects of tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments should be applied on a prospective basis. The nature of and reason for the change in accounting principle should be disclosed upon transition. The amendments in this update became effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 and did not have a material impact on the financial statements.

FASB ASC 820 – In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The updated guidance improves the disclosure requirements on fair value measurements. The ASU removes certain disclosures required by Topic 820 related to transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of transfers between levels; the valuation processes for Level 3 fair value measurements; and for nonpublic entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The ASU modifies certain disclosures required by Topic 820 related to disclosure of transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities for nonpublic entities; the requirement to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly for investments in certain entities that calculate net asset value; and clarification that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The ASU adds certain disclosure requirements related to changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update became effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2019 and did not have a material impact on the financial statements.

FASB ASC 350 – In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments in this update became effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years and did not have a material impact on the financial statements.

FASB ASC 842 – In March 2019, the FASB issued ASU No. 2019-01, Leases (Topic 842): Codification Improvements. The amendments in ASU No. 2019-01 align the guidance for fair value of the underlying asset by lessors that are not manufacturers or dealers in Topic 842 with that of existing guidance. As a result, the fair value of the underlying asset at lease commencement is its cost, reflecting any volume or trade discounts that may apply. However, if there has been a significant lapse of time between when the underlying asset is acquired and when the lease commences, the definition of fair value in Topic 820, Fair Value Measurement should be applied. ASU No. 2019-01 also requires lessors within the scope of Topic 942, Financial Services—Depository and Lending, to present all “principal payments received under leases” within investing activities. The amendments in this update became effective for annual periods and interim periods within those annual periods beginning after December 15, 2019 and did not have a material impact on the financial statements.

FASB ASC 326, 815, and 825 – In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments related to Topic 326 address accrued interest, transfers between classifications or categories for loans and debt securities, recoveries, vintage disclosures, and contractual extensions and renewal options and became effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. The improvements and clarifications related to Topic 815 address partial-term fair value hedges of interest-rate risk, amortization, and disclosure of fair value hedge basis adjustments and consideration of hedged contractually specified interest rate under the hypothetical method and became effective for the annual reporting period beginning January 1, 2020. The amendments related to Topic 825 contain various improvements to ASU 2016-01, including scope; held-to-maturity debt securities fair value disclosures; and remeasurement of equity securities at historical exchange rates and became effective for fiscal years and interim periods beginning after December 15, 2019. The amendments in this update did not have a material impact on the financial statements.

guidance around how to report expected recoveries for PCD assets. “Expected recoveries” describes a situation in which an organization recognizes a full or partial write-off of the amortized cost basis of a financial asset, but then later determines that the amount written off, or a portion of that amount, will in fact be recovered. This ASU permits organizations to record expected recoveries on PCD assets. In addition to other narrow technical improvements, the ASU also reinforces existing guidance that prohibits organizations from recognizing negative allowances for available-for-sale debt securities.

FASB ASC 718 – In November 2019, the FASB issued ASU No. 2019-08, Compensation – Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Codification Improvements—Share-Based Consideration Payable to a Customer. This ASU requires companies to measure and classify (on the balance sheet) share-based payments to customers by applying the guidance in Topic 718, Compensation—Stock Compensation. As a result, the amount recorded as a reduction in revenue would be measured based on the grant-date fair value of the share-based payment. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2019 and did not have a material impact on the consolidated financial statements.

FASB ASC 326 and 842 – In February 2020, the FASB issued ASU No. 2020-02, Financial Instruments—Credit Losses (Topic 326) and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842). This ASU inserts a paragraph to address the November 2019 issuance of SEC SAB 119, Accounting for Loan Losses by Registrants Engaged in Lending Activities Subject to FASB ASC Topic 326. The SAB updates existing staff guidance on developing a systematic methodology for estimating credit losses, and it explains the documentation the staff typically would expect from registrants in support of estimates of current expected credit losses for lending activities, when material. The amendments in this update became effective upon issuance and did not have a material impact on the consolidated financial statements.

FASB ASC 848 – In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the LIBOR or other interbank offered rate on financial reporting. To help with the transition to new reference rates, the ASU provides optional expedients and exceptions for applying GAAP to affected contract modifications and hedge accounting relationships. The main provisions include:

The guidance is applicable only to contracts or hedge accounting relationships that reference LIBOR or another reference rate expected to be discontinued. Because the guidance is meant to help entities through the transition period, it will be in effect for a limited time and will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients that are retained through the end of the hedging relationship. The amendments in this ASU are effective March 12, 2020 through December 31, 2022.

ASU 2020-04 permits relief solely for reference rate reform actions and permits different elections over the effective date for legacy and new activity. Accordingly, Old National is evaluating and reassessing the elections on a quarterly basis. For current elections in effect regarding the assertion of the probability of forecasted transactions, Old National elects the expedient to assert the probability of the hedged interest payments and receipts regardless of any expected modification in terms related to reference rate reform.

For Issue 1, Issue 2, Issue 4, and Issue 5, the amendments are effective upon issuance and did not have a material impact on the consolidated financial statements. For Issue 3, the amendments to ASU 2016-01 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years and did not have a material impact on the consolidated financial statements. For Issues 6 and 7, the amendments to ASU 2016-13 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years and did not have a material impact on the consolidated financial statements.

Guidance on Non-TDR Loan Modifications due to COVID-19 – On March 22, 2020, a statement was issued by our banking regulators and titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” (the “Interagency Statement”) that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of COVID-19. Additionally, Section 4013 of the CARES Act that passed on March 27, 2020 further provides that a qualified loan modification is exempt by law from classification as a TDR as defined by GAAP, from the period beginning March 1, 2020 until the earlier of December 31, 2020 or the date that is 60 days after the date on which the national emergency concerning the COVID-19 outbreak declared by the President of the United States under the National Emergencies Act terminates. Section 541 of the CAA extends this relief to the earlier of January 1, 2022 or 60 days after the national emergency termination date. The Interagency Statement was subsequently revised in April 2020 to clarify the interaction of the original guidance with Section 4013 of the CARES Act, as well as setting forth the banking regulators’ views on consumer protection considerations. In accordance with such guidance, we are offering short-term modifications made in response to COVID-19 to borrowers who are current and otherwise not past due. These include short-term (180 days or less) modifications in the form of payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. See Note 6 for further information on non-TDR loan modifications.

FASB ASC 715 – In August 2018, the FASB issued ASU No. 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this update modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments in this update become effective for fiscal years ending after December 15, 2020 and will not have a material impact on the consolidated financial statements.

FASB ASC 740 – In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim

FASB ASC 321, 323, and 815 – In January 2020, the FASB issued ASU No. 2020-01, Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (a Consensus of the Emerging Issues Task Force). The ASU clarifies the interaction between ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities and the ASU on equity method investments. ASU 2016-01 provides companies with an alternative to measure certain equity securities without a readily determinable fair value at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs. ASU 2020-01 clarifies that for purposes of applying the Topic 321 measurement alternative, an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting under Topic 323, immediately before applying or upon discontinuing the equity method. In addition, the new ASU provides direction that a company should not consider whether the underlying securities would be accounted for under the equity method or the fair value option when it is determining the accounting for certain forward contracts and purchased options, upon either settlement or exercise. The amendments in this update become effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, and the amendments are to be applied prospectively. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

FASB ASC 470 and 815 – In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, to clarify the accounting for certain financial instruments with characteristics of liabilities and equity. The amendments in this update reduce the number of accounting models for convertible debt instruments and convertible preferred stock by removing the cash conversion model and the beneficial conversion feature model. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in-capital. In addition, this ASU improves disclosure requirements for convertible instruments and earnings-per-share guidance. The ASU also revises the derivative scope exception guidance to reduce form-over-substance-based accounting conclusions driven by remote contingent events. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption will be permitted, but no earlier than for fiscal years beginning after December 15, 2020. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

Acquisitions and Dispositions of Businesses and Related Pro Forma Information – In May 2020, the SEC issued a final rule that revises the circumstances that require financial statements and related pro forma information for acquisitions and dispositions of businesses. The intent of the rule is to allow for more meaningful conclusions on when an acquired or disposed business is significant as well as to improve the related disclosure requirements. The changes are intended to improve the financial information about acquired or disposed businesses, facilitate more timely access to capital, and reduce the complexity and costs to prepare the disclosure. The final rule is effective January 1, 2021; however, voluntary early compliance is permitted.

FASB ASC 310 – In October 2020, the FASB issued ASU No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs, to clarify that an entity should reevaluate whether a callable debt security is within the scope of ASC paragraph 310-20-35-33 for each reporting period. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, and early application is not permitted. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

FASB ASC 470 – In October 2020, the FASB issued ASU No. 2020-09, Debt (Topic 470) Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762, which amends and supersedes various SEC paragraphs to reflect SEC Release No. 33-10762. That release amends the financial disclosure requirements applicable to registered debt offerings that include credit enhancements, such as subsidiary guarantees. These changes are intended to both improve the quality of disclosure and increase the likelihood that issuers will conduct debt offerings on a registered basis. The final rules are effective on January 4, 2021. Voluntary compliance with the final

Codification Improvements – In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements. The amendments improve codification by having all disclosure-related guidance available in the disclosure sections of the codification. Prior to this ASU, various disclosure requirements or options to present information on the face of the financial statements or as a note to the financial statements were not included in the appropriate disclosure sections of the codification. The codification improvements also contain various other minor amendments to codification that are not expected to have a significant effect on current accounting practice. The amendments are effective for annual periods beginning after December 15, 2020, and early application is permitted.
