Business and Basis of Financial Statement Presentation

BUSINESS

The PNC Financial Services Group, Inc. (PNC) is one of the largest diversified financial services companies in the United States (U.S.) and is headquartered in Pittsburgh, Pennsylvania.

We have businesses engaged in retail banking, including residential mortgage, corporate and institutional banking and asset management, providing many of our products and services nationally. Our retail branch network is located primarily in markets across the Mid-Atlantic, Midwest and Southeast. We also have strategic international offices in four countries outside the U.S.

Basis of Financial Statement Presentation

Our consolidated financial statements include the accounts of the parent company and its subsidiaries, most of which are wholly-owned, certain partnership interests and variable interest entities.

We prepared these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (GAAP). We have eliminated intercompany accounts and transactions.

In our opinion, the unaudited interim consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

We have also considered the impact of subsequent events on these consolidated financial statements.

When preparing these unaudited interim consolidated financial statements, we have assumed that you have read the audited consolidated financial statements included in our 2019 Form 10-K. These interim consolidated financial statements serve to update our 2019 Form 10-K and may not include all information and Notes necessary to constitute a complete set of financial statements. There have been significant changes to our accounting policies as disclosed in our 2019 Form 10-K due to the adoption of the current expected credit losses standard. The updated policies impacted by this adoption are included in this Note 1 in the first quarter of 2020. Reference is made to Note 1 Accounting Policies in our 2019 Form 10-K for a detailed description of all other significant accounting policies.

Use of Estimates

We prepared these consolidated financial statements using financial information available at the time of preparation, which requires us to make estimates and assumptions that affect the amounts reported. Our most significant estimates pertain to our fair value measurements and allowance for credit losses (ACL). Actual results may differ from the estimates and the differences may be material to the consolidated financial statements.

Recently Adopted Accounting Standards



Accounting Standards Update (ASU)	Description	Financial Statement Impact
Credit Losses- ASU 2016-13 Issued June 2016 Codification Improvements - ASU 2019-04 Various improvements related to Credit Losses (Topics 1, 2 and 5) Issued April 2019 Targeted Transition Relief - Credit Losses - ASU 2019-05 Issued May 2019 Codification Improvements - ASU 2019-11 Issued November 2019	• Commonly referred to as the Current Expected Credit Losses (CECL) standard. •Replaces measurement, recognition and disclosure guidance for credit related reserves (i.e., the allowance for loan and lease losses (ALLL) and the allowance for unfunded loan commitments and letters of credit) and Other than Temporary Impairment (OTTI) for debt securities. •Requires the use of an expected credit loss methodology; specifically, current expected credit losses for the remaining life of the asset will be recognized starting from the time of origination or acquisition. •Methodology applies to loans, net investment in leases, debt securities and certain financial assets not accounted for at fair value through net income. It also applies to unfunded lending related commitments except for unconditionally cancellable commitments. •In-scope assets are presented at the net amount expected to be collected after the deduction or addition of the ACL from the amortized cost basis of the assets. • Requires inclusion of expected recoveries of previously charged-off amounts for in-scope assets. • Requires enhanced credit quality disclosures including disaggregation of credit quality indicators by vintage. • Requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings at adoption.	• Adopted January 1, 2020 under the modified retrospective approach. The cumulative-effect adjustment to retained earnings totaled $671 million at adoption. • Amended presentation and disclosures are required prospectively. Refer to the disclosures in this Note 1, Note 2 Investment Securities, Note 3 Loans and Note 9 Total Equity and Other Comprehensive Income for additional information. • With the adoption of CECL, we discontinued the accounting for purchased impaired loans and elected the one-time fair value option election for some of these loans and certain residential real estate collateral dependent loans. Loans that were previously accounted for as purchased impaired where the fair value option election was not made are now accounted for as purchased credit deteriorated loans. • There was no impact to the recorded investment of our investment securities or loans, except for our purchased credit deteriorated loan portfolio. Accounting for these loans as purchased credit deteriorated required an adjustment to the remaining accretable discount and recorded investment in addition to the impact on ACL due to the adoption of CECL methodology. • Refer to Table 33 for a summary of the impact of the CECL standard adoption.
Accounting Standards Update (ASU)	Description	Financial Statement Impact
Codification Improvements - ASU 2019-04 Topic 3: Codification Improvements to ASU 2017-12 and Other Hedging Items Issued April 2019	• Targeted improvements related to: - Partial-term fair value hedges of interest rate risk - Amortization of fair value hedge basis adjustments - Disclosure of fair value hedge basis adjustments - Consideration of the hedged contractually specified interest rate under the hypothetical derivative method - Application of a first-payments-received cash flow hedging technique to overall cash flows on a group of variable interest payments - Update to transition guidance for ASU 2017-12 • This ASU permits a one-time transfer out of held to maturity securities to provide entities the opportunity to hedge fixed rate, prepayable securities under a last of layer hedging strategy (although an entity is not required to hedge such securities subsequent to transfer).	• Adopted January 1, 2020. • As permitted by the eligibility requirements in this guidance, at adoption we elected to transfer debt securities with an amortized cost of $16.2 billion (fair value of $16.5 billion) from held to maturity to the available for sale portfolio. The transfer resulted in a pretax increase to AOCI of $306 million. There were no other impacts to PNC's consolidated financial statements from the adoption of this guidance.
Accounting Standards Update (ASU)	Description	Financial Statement Impact
Goodwill - ASU 2017-04 Issued January 2017	• Eliminates Step 2 from the goodwill impairment test to simplify the subsequent measurement of goodwill under which a loss was recognized only if the estimated implied fair value of the goodwill is below its carrying value. • Requires impairment to be recognized if the reporting unit's carrying value exceeds the fair value.	• Adopted January 1, 2020. • The adoption of this standard did not impact our consolidated results of operations or our consolidated financial position.



Accounting Standards Update (ASU)	Description	Financial Statement Impact
Reference Rate Reform - ASU 2020-04 Issued March 2020	• Provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. • Includes optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables), were not substantial (assets within the scope of ASC 470, Debt), and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases, and other Topics) of the existing contract. • Includes optional expedients related to hedging relationships within the scope of ASC 815, Derivatives & Hedging, whereby changes to the critical terms of a hedging relationship do not require dedesignation if certain criteria are met. In addition, potential sources of ineffectiveness as a result of reference rate reform may be disregarded when performing some effectiveness assessments. • Allows for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. • Guidance in this ASU is effective as of March 12, 2020 through December 31, 2022.	• Adopted March 12, 2020, will apply prospectively. • As of March 31, 2020, we have not yet elected any optional expedients outlined in this ASU. However, we plan to elect these optional expedients in the future.

The following table presents the impact of adopting the CECL standard on January 1, 2020 on our allowance and retained earnings.

Cash, Cash Equivalents and Restricted Cash

Cash and due from banks are considered cash and cash equivalents for financial reporting purposes because they represent a primary source of liquidity. Certain cash balances within Cash and due from banks on our Consolidated Balance Sheet are restricted as to withdrawal or usage by legally binding contractual agreements or regulatory requirements.

Investments

We hold interests in various types of investments. The accounting for these investments is dependent on a number of factors including,

but not limited to, items such as:

• Ownership interest,

• Our plans for the investment, and

• The nature of the investment.

Debt Securities

Debt securities are recorded on a trade-date basis. We classify debt securities as either trading, held to maturity, or available for sale. Debt securities that we purchase for certain risk management activities or customer-related trading activities are classified as trading securities, are reported in the Other assets line item on our Consolidated Balance Sheet, and are carried at fair value. Realized and unrealized gains and losses on trading securities are included in Other noninterest income. We classify debt securities as held to maturity when we have the positive intent and ability to hold the securities to maturity, and carry them at amortized cost, less any ACL. Debt securities not classified as held to maturity or trading are classified as securities available for sale, and are carried at fair value. Unrealized gains and losses on available for sale securities are included in Accumulated other comprehensive income (AOCI) net of income taxes.

We include all interest on debt securities, including amortization of premiums and accretion of discounts on investment securities, in

net interest income using the constant effective yield method generally calculated over the contractual lives of the securities. Effective

yields reflect either the effective interest rate implicit in the security at the date of acquisition or, for debt securities where an other-than-temporary impairment was recorded, the effective interest rate determined based on improved cash flows subsequent to an

impairment. We compute gains and losses realized on the sale of available for sale debt securities on a specific security basis. These

securities gains/(losses) are included in Other noninterest income on the Consolidated Income Statement.

As discussed in the Recently Adopted Accounting Standards section of this Note 1, we adopted the CECL standard as of January 1,

2020, which requires expected credit losses on both held to maturity and available for sale securities to be recognized through a

valuation allowance, ACL, instead of as a direct write-down to the amortized cost basis of the security. An available for sale security is considered impaired if the fair value is less than amortized cost basis. If any portion of the decline in fair value is related to credit, the amount of ACL is determined as the portion related to credit, limited to the difference between the amortized cost basis and the fair value of the security. If we have the intent to sell or believe it is more likely than not we will be required to sell an impaired available for sale security before recovery of the amortized cost basis, the credit loss is recorded as a direct write-down of the amortized cost basis. Credit losses on investment securities are recognized through the Provision for credit losses on our Consolidated Income Statement. Declines in the fair value of available for sale securities that are not considered credit related are recognized in AOCI on our Consolidated Balance Sheet. The CECL standard is applied prospectively to debt securities and, as a result, the amortized cost basis of investment securities for which OTTI had previously been recorded did not change upon adoption. For information on the policies previously applied to determine OTTI, see the Debt Securities section of Note 1 Accounting Policies in our 2019 Form 10-K.

We consider a security to be past due in terms of payment based on its contractual terms. A security may be placed on nonaccrual, with

interest no longer recognized until received, when collectability of principal or interest is doubtful. As of March 31, 2020, nonaccrual or past due held-to-maturity securities were immaterial.

A security may be partially or fully charged off against the ACL if it is determined to be uncollectible, including, for an available for

sale security, if we have the intent to sell or believe it is more likely than not we will be required to sell the security before recovery of

the amortized cost basis. Recoveries of previously charged-off available for sale securities are recognized when received, while

recoveries on held to maturity securities are recognized when expected.

See the Allowance for Credit Loss section of this Note 1 for further discussion regarding the methodologies used to determine the

ACL on investment securities. See Note 2 Investment Securities for additional information about the investment securities portfolio

and the related ACL.

Loans

Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable

future, or until maturity or payoff. Management’s intent and view of the foreseeable future may change based on changes in business

strategies, the economic environment, market conditions and the availability of government programs.

Measurement of delinquency status is based on the contractual terms of each loan. Loans that are 30 days or more past due in terms of

payment are considered delinquent.

Loans held for investment, excluding purchased credit deteriorated loans, are recorded at amortized cost basis unless we elect to measure these under the fair value option. Amortized cost basis represents principal amounts outstanding, net of unearned income, unamortized deferred fees, costs on originated loans, and premiums or discounts on purchased loans, and charge-offs. Amortized cost basis does not include accrued interest, as we include accrued interest in Other Assets on our Consolidated Balance Sheet. Interest on performing loans is accrued based on the principal amount outstanding and recorded in Interest income as earned using the constant effective yield method. Loan origination fees, direct loan origination costs, and loan premiums and discounts are deferred and accreted or amortized into Net interest income using the constant effective yield method, over the contractual life of the loan. Loans under the fair value option are reported at their fair value, with any changes to fair value reported as Noninterest income on the Consolidated Income Statement, and are excluded from measurement of ACL.

In addition to originating loans, we also acquire loans through the secondary loan market, portfolio purchases or acquisitions of other

financial services companies. Certain acquired loans that have experienced a deterioration of credit quality since origination (i.e.,

purchased credit deteriorated) are recognized at fair value. ACL for purchased credit deteriorated loans is measured at the acquisition date and added to the acquisition date fair value to determine the amortized cost basis for these loans. Subsequent decreases in expected cash flows that are attributable, at least in part, to credit quality are recognized through a charge to the provision for credit losses resulting in an increase in the ACL. Subsequent increases in expected cash flows are recognized as a provision recapture of previously recorded ACL.

We consider a loan to be collateral dependent when we determine that substantially all of the expected cash flows will be generated

from the operation or sale of the collateral underlying the loan, the borrower is experiencing financial difficulty and we have elected to

measure the loan at the estimated fair value of collateral (less costs to sell if sale or foreclosure of the property is expected).

Additionally, we consider a loan to be collateral dependent when foreclosure or liquidation of the underlying collateral is probable.

See the Allowance for Credit Losses section of this Note 1 for further discussion regarding the methodologies and significant inputs

used to determine the ACL on loans. See Note 3 Loans for additional information about our loan portfolio and the related ACL.

Loans Held for Sale

We designate loans as held for sale when we have the intent to sell them. At the time of designation to held for sale, any ACL is

reversed, and a valuation allowance for shortfall between the amortized cost basis and the net realizable value is recognized, excluding

the amounts already charged off. Similarly, when loans are no longer considered held for sale, the valuation allowance (net of writedowns) is reversed, and an allowance for credit losses is established, excluding the amounts already charged-off. Write-downs on these loans (if required) are recorded as charge-offs through the valuation allowance. Adjustments to the valuation allowance on held for sale loans are recognized in Other noninterest income.

We have elected to account for certain commercial and residential mortgage loans held for sale at fair value. The changes in the fair

value of the commercial mortgage loans are measured and recorded in Other noninterest income while such changes for the residential

mortgage loans are measured and recorded in Residential mortgage noninterest income each period. See Note 11 Fair Value for

additional information.

Interest income with respect to loans held for sale is accrued based on the principal amount outstanding and the loan’s contractual

interest rate.

In certain circumstances, loans designated as held for sale may be transferred to held for investment based on a change in strategy. We

transfer these loans at the lower of cost or estimated fair value; however, any loans originated or purchased as held for sale for which the fair value option has been elected remain at fair value for the life of the loan.

Nonperforming Loans and Leases

The matrix below summarizes our policies for classifying certain loans as nonperforming loans and/or discontinuing the accrual of

loan interest income.



Commercial lending
Loans Classified as Nonperforming and Accounted for as Nonaccrual		• Loans accounted for at amortized cost where: – The loan is 90 days or more past due. – The loan is rated substandard or worse due to the determination that full collection of principal and interest is not probable as demonstrated by the following conditions: • The collection of principal or interest is 90 days or more past due; • Reasonable doubt exists as to the certainty of the borrower’s future debt service ability, according to the terms of the credit arrangement, regardless of whether 90 days have passed or not; • The borrower has filed or will likely file for bankruptcy; • The bank advances additional funds to cover principal or interest; • We are in the process of liquidating a commercial borrower; or • We are pursuing remedies under a guarantee.
Loans Excluded from Nonperforming Classification but Accounted for as Nonaccrual		• Loans accounted for under the fair value option and full collection of principal and interest is not probable. • Loans accounted for at the lower of cost or market less costs to sell (held for sale) and full collection of principal and interest is not probable.
Loans Excluded from Nonperforming Classification and Nonaccrual Accounting		• Loans that are well secured and in the process of collection.



Consumer lending
Loans Classified as Nonperforming and Accounted for as Nonaccrual		• Loans accounted for at amortized cost where full collection of contractual principal and interest is not deemed probable as demonstrated in the policies below: – The loan is 90 days past due for home equity and installment loans, and 180 days past due for well secured residential real estate loans; – The loan has been modified and classified as a troubled debt restructuring (TDR); – Notification of bankruptcy has been received; – The bank holds a subordinate lien position in the loan and the first lien mortgage loan is seriously stressed (i.e., 90 days or more past due); – Other loans within the same borrower relationship have been placed on nonaccrual or charge-offs have been taken on them; – The bank has ordered the repossession of non-real estate collateral securing the loan; or – The bank has charged-off the loan to the value of the collateral.
Loans Excluded from Nonperforming Classification but Accounted for as Nonaccrual		• Loans accounted for under the fair value option and full collection of principal and interest is not probable. • Loans accounted for at the lower of cost or market less costs to sell (held for sale) and full collection of principal and interest is not probable.
Loans Excluded from Nonperforming Classification and Nonaccrual Accounting		• Certain government insured loans where substantially all principal and interest is insured. • Residential real estate loans that are well secured and in the process of collection. • Consumer loans and lines of credit, not secured by residential real estate or automobiles, as permitted by regulatory guidance.

Commercial Lending

We generally charge off Commercial Lending (Commercial, Commercial Real Estate, and Equipment Lease Financing)

nonperforming loans when we determine that a specific loan, or portion thereof, is uncollectible. This determination is based on the

specific facts and circumstances of the individual loans. In making this determination, we consider the viability of the business or

project as a going concern, the past due status when the asset is not well-secured, the expected cash flows to repay the loan, the

value of the collateral, and the ability and willingness of any guarantors to perform.

Additionally, in general, for smaller commercial loans of $1 million or less, a partial or full charge-off occurs at 120 days past due

for term loans and 180 days past due for revolvers. Certain small business credit card balances that are placed on nonaccrual status

when they become 90 days or more past due are charged-off at 180 days past due.

Consumer Lending

We generally charge off secured consumer (Home equity, Residential Real Estate and Automobile) nonperforming loans to the fair

value of collateral less costs to sell, if lower than the amortized cost basis of the loan outstanding, when delinquency of the loan, combined with other risk factors (e.g., bankruptcy, lien position, or troubled debt restructuring), indicates that the loan, or some portion thereof, is uncollectible as per our historical experience, or the collateral has been repossessed. We charge-off secured

consumer loans no later than 180 days past due. Most consumer loans and lines of credit, not secured by residential real estate, are

charged off once they have reached 120-180 days past due.

For secured collateral dependent loans, collateral values are updated at least annually and subsequent declines in collateral values are charged-off resulting in incremental provision for credit loss. Subsequent increases in collateral values may be reflected as an adjustment to ACL to reflect the expectation of recoveries in an amount greater than previously expected.

Accounting for Nonperforming Assets and Leases and Other Nonaccrual Loans

For nonaccrual loans, interest income accrual and deferred fee/cost recognition is discontinued. Additionally, the current year accrued and uncollected interest is reversed through Net interest income and prior year accrued and uncollected interest is charged-off, except for credit cards, where we reverse any accrued interest through Net interest income at the time of charge-off, as per industry standard practice. Nonaccrual loans that are also collateral dependent may be charged-off to reduce the basis to the fair value of collateral less costs to sell.

If payment is received on a nonaccrual loan, generally the payment is first applied to the remaining principal balance; payments are then applied to recover any charged-off amounts related to the loan. Finally, if both principal balance and any charge-offs have been recovered, then the payment will be recorded as fee and interest income. For certain consumer loans, the receipt of interest payments is recognized as interest income on a cash basis. Cash basis income recognition is applied if a loan’s amortized cost basis is deemed fully collectible and the loan has performed for at least six months.

For TDRs, payments are applied based upon their contractual terms unless the related loan is deemed non-performing. TDRs are

generally included in nonperforming and nonaccrual loans. However, after a reasonable period of time, generally six months, in which the loan performs under restructured terms and meets other performance indicators, it is returned to performing/accruing status. This return to performing/accruing status demonstrates that the bank expects to collect all of the loan’s remaining contractual principal and interest. TDRs resulting from (i) borrowers that have been discharged from personal liability through Chapter 7 bankruptcy and have not formally reaffirmed their loan obligations to us, and (ii) borrowers that are not currently obligated to make both principal and interest payments under the restructured terms are not returned to accrual status.

Other nonaccrual loans are generally not returned to accrual status until the borrower has performed in accordance with the

contractual terms and other performance indicators for at least six months, the period of time which was determined to demonstrate

the expected collection of the loan’s remaining contractual principal and interest. Nonaccrual loans with partially charged-off principal are not returned to accrual. When a nonperforming loan is returned to accrual status, it is then considered a performing loan.

Foreclosed assets consist of any asset seized or property acquired through a foreclosure proceeding or acceptance of a deed-in-lieu

of foreclosure. Other real estate owned (OREO) comprises principally commercial and residential real estate properties obtained in

partial or total satisfaction of loan obligations. After obtaining a foreclosure judgment, or in some jurisdictions the initiation of

proceedings under a power of sale in the loan instruments, the property will be sold. When we are awarded title or completion of

deed-in-lieu of foreclosure, we transfer the loan to foreclosed assets included in Other assets on our Consolidated Balance Sheet.

Property obtained in satisfaction of a loan is initially recorded at estimated fair value less cost to sell. Based upon the estimated fair

value less cost to sell, the amortized cost basis of the loan is adjusted and a charge-off/recovery is recognized to the ACL. We

estimate fair values primarily based on appraisals, or sales agreements with third parties. Subsequently, foreclosed assets are

valued at the lower of the amount recorded at acquisition date or estimated fair value less cost to sell. Valuation adjustments on

these assets and gains or losses realized from disposition of such property are reflected in Other noninterest expense.

For certain mortgage loans that have a government guarantee, we establish a separate other receivable upon foreclosure. The

receivable is measured based on the loan balance (inclusive of principal and interest) that is expected to be recovered from the

guarantor.

See Note 3 Loans in this Report for additional information on nonperforming assets, TDRs and credit quality indicators related to our loan portfolio.

Allowance for Credit Losses

Our ACL, in accordance with the CECL standard, is based on historical loss experience, borrower characteristics, current economic

conditions, reasonable and supportable forecasts of future conditions and other relevant factors. We maintain the ACL at an

appropriate level for expected losses on our existing investment securities, loans, finance leases (including residual values), trade

receivables and other financial assets and unfunded lending related commitments, for the estimated contractual term of the assets or

exposures as of the balance sheet date. We estimate the estimated contractual term of assets in scope of CECL considering

contractual maturity dates, prepayment expectations, utilization or draw expectations and any embedded extension options that do

not allow us to unilaterally cancel the extension options. For products without a fixed contractual maturity date (e.g., credit cards),

we rely on historical payment behavior to determine the length of the pay down or default time period.

We estimate expected losses on a pooled basis using a combination of (i) the expected losses over a reasonable and supportable

forecast period (RSFP), (ii) a period of reversion to long run average expected losses (reversion period) where applicable, and (iii)

long run average (LRA) expected losses for the remaining estimated contractual term. For all assets and unfunded lending related commitments in the scope of CECL, the ACL also includes individually assessed reserves and qualitative reserves, as

applicable.

We use forward-looking information in estimating expected credit losses for the RSFP. For this purpose, we use the forecasted

scenarios produced by PNC's Economics Team, which are designed to reflect business cycles and their related estimated probabilities. The forecast length that we have determined to be reasonable and supportable is three years. As noted in the methodology discussions that follow, forward looking information, such as forecasted relevant macroeconomic variables, is incorporated into the expected credit loss estimates using quantitative techniques, as well as through analysis from PNC economists and management judgment.

The reversion period is used to bridge RSFP and LRA expected credit losses. We may consider a number of factors in determining the duration of the reversion period, such as contractual maturity of the asset, observed historical patterns and the estimated credit loss rates at the end of RSFP relative to the beginning of the LRA period.

The LRA expected credit losses are derived from long run historical credit loss information adjusted for the credit quality of the current portfolio, and therefore do not consider current and forecasted economic conditions.

See the following sections related to investment securities, loans, trade receivables, other financial assets and unfunded lending related commitments for details about specific methodologies.

Allowance for Credit Losses - Investment Securities

A significant portion of our investment securities are issued or guaranteed by either the U.S. government (U.S. Treasury or Government National Mortgage Association (GNMA)) or a government-sponsored agency (Federal National Mortgage Association (FNMA) or Federal Home Loan Mortgage Corporation (FHLMC)). Taking into consideration historical information and current and forecasted conditions, we do not expect to incur any credit losses on these securities.

Investment securities that are not issued or guaranteed by the U.S. government or a government-sponsored agency consist of both securitized products, such as non-agency mortgage and asset-backed securities, as well as non-securitized products, such as corporate and municipal debt securities. A discounted cash flow approach is primarily used to determine the amount of the ACL required. The estimates of expected cash flows are determined using macroeconomic sensitive models taking into consideration the RSFP and scenarios discussed above. The cash flows expected to be collected, after considering expected prepayments, are discounted at the effective interest rate. For an available-for-sale security, the amount of the ACL is limited to the difference between the amortized cost basis of the security and its estimated fair value.

See Note 2 Investment Securities in this Report for additional information about the investment securities portfolio.

Allowance for Credit Losses - Loans and Leases

Our pooled expected loss methodology is based upon the quantification of risk parameters, such as probability of default (PD), loss

given default (LGD) and exposure at default (EAD) for a loan or loan segment. We also consider the impact of prepayments and

amortization on contractual maturity in our expected loss estimates. We use historical credit loss information, current borrower

characteristics and forecasted economic variables for the RSFP, coupled with analytical methods, to estimate these risk parameters

by loan or loan segments. PD, LGD and EAD parameters are calculated for each forecasted scenario and the LRA period, and

combined to generate expected loss estimates by scenario. The following matrix provides key credit risk characteristics that we use to

estimate these risk parameters.



Loan Class	Probability of Default (PD)	Loss Given Default (LGD)	Exposure at Default (EAD)
Commercial Lending
Commercial and Equipment Lease Financing	• For wholesale obligors: internal risk ratings based on borrower characteristics and industry • For retail small balance obligors: credit scores, exposure characteristics and industry	• Collateral type, collateral value, industry, size and outstanding exposure for secured loans • Capital structure, industry and size for unsecured loans • Product type and credit scores	• Outstanding balances, contractual maturities and historical prepayment experience • Product type and historical prepayment experience
Commercial Real Estate	• Property performance metrics and capitalization rates for RSFP • Internal risk ratings based on borrower characteristics for LRA	• Property values and anticipated liquidation costs	• Outstanding balances, contractual maturities, historical prepayment experience and contractual extension options
Consumer Lending
Home Equity and Residential Real Estate	• Borrower credit scores, delinquency rates, origination vintage, loan-to-value (LTV) ratios and contractual maturity	• Collateral characteristics, LTV and costs to sell	• Outstanding balances, contractual maturities and historical prepayment experience
Automobile	• Borrower credit scores, borrower income, LTV and contractual maturity	• New vs. used, LTV and borrower credit scores	• Outstanding balances, contractual maturities and historical prepayment experience
Credit Card	• Borrower credit scores, customer type (individual vs. joint) and months on book	• Borrower credit scores	• Pay-down curves estimated using borrower behavior segments, payment ratios and borrower credit scores • Payment ratios are developed using a pro-rata method
Education and Other Consumer	• Net charge-off rates by vintage are used to estimate expected losses in lieu of discrete risk parameters

The following matrix describes the key economic variables that are consumed during the RSFP by loan class, as well as other

assumptions that are used for our reversion and LRA approaches.



Loan Class	RSFP - Key Economic Variables	Reversion Method	LRA Approach
Commercial Lending
Commercial and Equipment Lease Financing	• Gross Domestic Product and Gross Domestic Income measures, imports, unemployment rates, House Price Index (HPI), credit spreads, personal income and consumption measures and stock market indices	• Immediate reversion	• Average parameters determined based on internal and external historical data • Modeled parameters using long run economic conditions for retail small business obligors
Commercial Real Estate	• Unemployment rates, Commercial Property Price Index, stock market indices /volatility measures, and interest rates	• Immediate reversion	• Average parameters determined based on internal and external historical data
Consumer Lending
Home Equity and Residential Real Estate	• Unemployment rates, HPI and interest rates	• Straight-line over 1-3 years based on economic scenario	• Modeled parameters using long run economic conditions
Automobile	• Unemployment rates, HPI, personal consumption, interest rates, Manheim used car index and domestic oil prices	• Straight-line over 1 year	• Average parameters determined based on internal and external historical data
Credit Card	• Unemployment rates, delinquency rates, personal consumption, HPI and housing data	• Straight-line over 2 years	• Modeled parameters using long run economic conditions
Education and Other Consumer	• Net charge-off rates by vintage are used to estimate expected losses in lieu of discrete risk parameters

After the RSFP, we revert to the LRA over the reversion period noted above, which is the period between the end of the RSFP and

when losses are estimated to have completely reverted to the LRA.

Once we have developed a combined estimate of credit losses (i.e., of the RSFP, reversion period and LRA) under each of the forecasted scenarios, we produce a probability-weighted credit loss estimate by loan class. We then add or deduct any qualitative components and other adjustments, such as individually assessed loans, to produce the ACL. See the Individually Assessed Component and Qualitative Component sections of this Note 1 for additional information about those adjustments.

Discounted Cash Flow

In addition to TDRs, we also use a discounted cash flow methodology for our Home Equity and Residential Real Estate loan classes. We determine effective interest rates considering contractual cash flows adjusted for estimated prepayments. Changes in the ACL due to the impact of the passage of time under the discounted cash flow estimate are recognized through the provision for credit losses.

Individually Assessed Component

Loans and leases that do not share similar risk characteristics with a pool of loans are individually assessed as follows:

•

For commercial nonperforming loans greater than or equal to a defined dollar threshold, reserves are based on an analysis of the present value of the loan’s expected future cash flows or the fair value of the collateral, if appropriate under our policy for collateral dependent loans. Nonperforming commercial loans below the defined threshold and accruing TDRs are reserved for under a pooled basis.


•	For consumer nonperforming loans classified as collateral dependent, charge-off and ACL related to recovery of amounts previously charged-off are evaluated through an analysis of the fair value of the collateral less costs to sell.

Qualitative Component

While our reserve methodologies strive to reflect all relevant credit risk factors, there continues to be uncertainty associated with,

but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal

variations between expected and actual outcomes. We may hold additional reserves that are designed to provide coverage for losses

attributable to such risks. The ACL also takes into account factors that may not be directly measured in the determination of

individually assessed or pooled reserves. Such qualitative factors may include, but are not limited to:


•	Industry concentrations and conditions,


•	Changes in market conditions, including regulatory and legal requirements,


•	Changes in the nature and volume of our portfolio,


•	Recent credit quality trends,


•	Recent loss experience in particular portfolios, including specific and unique events,


•	Recent macro-economic factors that may not be reflected in the forecast information,


•	Limitations of available data, including historical loss information and recent data such as collateral values,


•	Model imprecision,


•	Changes in lending policies and procedures, including changes in loss recognition and mitigation policies and procedures,


•	Timing of available information, including the performance of first lien positions, and


•	Other relevant factors

See Note 3 Loans for additional information about our loan portfolio and the related allowance.

Accrued Interest

When accrued interest is reversed or charged-off in a timely manner the CECL standard provides a practical expedient to exclude

accrued interest from ACL measurement. We consider our nonaccrual and charge-off policies to be timely for all of our investment

securities, loans and leases, with the exception of consumer credit cards, education loans and certain unsecured consumer lines of credit. We consider the length of time before nonaccrual/charge-off and the use of appropriate other triggering events for nonaccrual and charge-offs in making this determination. Pursuant to these policy elections, we calculate reserves for accrued interest on credit cards, education loans and certain consumer lines of credit, which are then included within the ACL for loans and leases. See the Debt Securities and Nonperforming Loans and Leases sections of this Note 1 for additional information on our nonaccrual and charge-off policies.

Additionally, pursuant to our use of a discounted cash flow methodology in estimating credit losses for our home equity and residential real estate loan classes, applicable reserves for accrued interest are also included within the ACL for loans and leases for these loan classes.

Purchased Credit Deteriorated Loans or Securities

The ACL for purchased credit deteriorated loans or securities is determined at the time of acquisition, as the estimated expected credit loss of the outstanding balance or par value, based on the methodologies described previously for loans and securities. In accordance with CECL, the ACL recognized at acquisition is added to the acquisition date purchase price to determine the asset’s amortized cost basis.

Allowance for Credit Losses - Unfunded Lending Related Commitments

We maintain the ACL for unfunded lending related commitments on off-balance sheet credit exposures that are not unconditionally cancelable (e.g., unfunded loan commitments, letters of credit and certain financial guarantees), at a level we believe is appropriate as of the balance sheet date to absorb expected credit losses on these exposures. Other than the estimation of the probability of funding, this reserve is estimated in a manner similar to the methodology used for determining reserves for loans and leases. The ACL for unfunded lending related commitments is recorded as a liability on the Consolidated Balance Sheet. Net adjustments to this reserve are included in the provision for credit losses.

See Note 3 Loans for additional information about this allowance.

Allowance for Credit Losses - Other Financial Assets

We determine the allowance for other financial assets (e.g., trade receivables, servicing advances, balances with banks) considering historical loss information and other available indicators. In certain cases where there are no historical, current or forecast indicators of an expected credit loss, we may estimate the reserve to be close to zero. As of March 31, 2020, the ACL for other financial assets was immaterial.

Goodwill

Goodwill arising from business acquisitions represents the value attributable to unidentifiable intangible elements in the business acquired. At least annually, in the fourth quarter, or more frequently if events occur or circumstances have changed significantly from the annual test date, management performs our goodwill impairment test at a reporting unit level.

PNC has the ability to first perform a qualitative analysis to evaluate whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If, after considering all relevant events and circumstances, PNC determines it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative impairment test is not necessary. If PNC elects to bypass the qualitative analysis, or concludes via qualitative analysis that it is more-likely-than-

not that the fair value of a reporting unit is less than its carrying amount, a quantitative goodwill impairment test is performed. Inputs are generated and used in calculating the fair value of the reporting unit, which is compared to its carrying amount. The fair value of our reporting units is determined by using discounted cash flows and/or market comparability methodologies. If the fair value is greater than the carrying amount, then the reporting unit's goodwill is deemed not to be impaired. If the fair value is less than the carrying amount, an entity should recognize an impairment charge for the amount by which the carrying amount of goodwill exceeds the reporting unit’s fair value. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.
