Old Second Reports Second Quarter Net Income of $9.2 million, or $0.31 per Diluted Share

​

AURORA, IL, July 22, 2020 – Old Second Bancorp, Inc. (the “Company,” “we,” “us,” and “our”) (NASDAQ: OSBC), the parent company of Old Second National Bank (the “Bank”), today announced financial results for the second quarter of 2020. Our net income was $9.2 million, or $0.31 per diluted share, for the second quarter of 2020, compared to net income of $275,000, or $0.01 per diluted share, for the first quarter of 2020, and net income of $9.3 million, or $0.31 per diluted share, for the second quarter of 2019. Net income for the second quarter of 2020 includes a ($0.05) per diluted share impact of additional provisions for credit losses for loans and unfunded commitments due to changes in economic conditions and market interest rates related to the COVID-19 pandemic.

Operating Results

●Second quarter 2020 net income was $9.2 million, reflecting an increase in earnings of $9.0 million from the first quarter of 2020, and a decrease in earnings of $40,000 from the second quarter of 2019. We recorded a provision for credit losses of $2.1 million in the second quarter of 2020, compared to $8.0 million in the first quarter of 2020, both due to the assessment of potential credit losses related to the COVID-19 pandemic under the new current expected credit losses accounting standard (“CECL”). Also contributing to the increase in net income in the second quarter of 2020 compared to the prior quarter was growth in net gain on sales of mortgage loans of $2.4 million due to the reduction of interest rates, a reduction of $1.7 million of mark to market losses on MSRs, and the recognition of $635,000 in deferred issuance costs due to the redemption of our 7.80% cumulative trust preferred securities issued by Old Second Capital Trust I and related junior subordinated debentures, resulting in $32.6 million of debt retirement, in the first quarter of 2020.
●Net interest and dividend income was $22.7 million for the second quarter of 2020, a decrease of $49,000, or 0.2%, from the first quarter of 2020, and a decrease of $2.0 million, or 8.3%, from the second quarter of 2019. Net interest and dividend income in the year over year period was negatively impacted by interest rate reductions related to COVID-19, which more than offset increases in interest income due to loan growth in the same period. The recognition of $635,000 in deferred issuance costs due to the redemption of trust preferred securities issued by Old Second Capital Trust I and related junior subordinated debentures also reduced net interest and dividend income in the first quarter of 2020.
●Provision for credit losses was $2.1 million for the second quarter of 2020, consisting of $1.4 million related to loans and $734,000 related to unfunded commitments, compared to a provision for credit losses of $8.0 million for the first quarter of 2020, consisting of $5.5 million related to loans and $2.5 million related to unfunded commitments, and a provision for loan losses of $450,000 in the second quarter of 2019. We adopted the new CECL accounting standard effective January 1, 2020, which measures the allowance based on management’s best estimate of lifetime expected credit losses inherent in our lending activities, resulting in a $5.9 million allowance related to loans and a $1.7 million allowance related to unfunded commitments in the first quarter of 2020. Provision expense in 2020 was impacted by both the adoption of the new CECL methodology and the expected impact, as of June 30, 2020, of the COVID-19 pandemic on future losses.
●Noninterest income was $10.7 million for the second quarter of 2020, an increase of $4.4 million, or 69.2%, compared to $6.3 million for the first quarter of 2020, and an increase of $2.6 million, or 31.3%, compared to $8.1 million for the second quarter of 2019. The increase compared to the linked quarter and year over year quarter was primarily due to growth in net gains on sales of mortgage loans, due to an increase in volumes of originations and renewals in the lower interest rate environment. In addition, mark to market losses on MSRs

totaled $445,000 in the second quarter of 2020, compared to losses of $2.1 million in the first quarter of 2020, and losses of $1.1 million in the second quarter of 2019.

| ● | Noninterest expense was $18.9 million for the second quarter of 2020, a decrease of $2.1 million, or 10.0%, compared to $21.0 million for the first quarter of 2020, and a decrease of $1.2 million, or 6.1%, from $20.1 million for the second quarter of 2019. The decrease compared to the linked quarter and the year over year quarter was primarily attributable to decreases in salaries and employee benefits, computer and data processing, advertising, and other real estate owned expenses.

| ● | The provision for income taxes expense was $3.1 million for the second quarter of 2020, compared to a net benefit of $281,000 for the first quarter of 2020, and $3.0 million of provision expense for the second quarter of 2019. The increase in tax expense for the linked quarter was due to an increase of $12.4 million in pretax income compared to the first quarter of 2020.

| ● | During the second quarter of 2020, we repurchased 145,932 shares of our common stock at a weighted average price of $6.97 per share pursuant to our stock repurchase program.

| ● | On July 21, 2020, our Board of Directors declared a cash dividend of $0.01 per share payable on August 10, 2020, to stockholders of record as of July 31, 2020.

COVID-19 Operational Update

During this unprecedented time, the health and safety of our customers and employees remain our top priority.

| ● | We established client assistance programs, including offering commercial, consumer, and mortgage loan payment deferrals for certain clients. We also suspended late fees for consumer loans through June 30, 2020, and, although consumer late fees have been reinstated, we will continue to re-evaluate late fee assessments based on the ongoing COVID-19 pandemic.

| ● | We paused new foreclosure and repossession actions through June 30, 2020, and will continue to re-evaluate based on the borrower’s financial status and capability of repayment.

| ● | We are participating in the Coronavirus Aid, Relief and Economic Security Act (“CARES” Act). As of June 30, 2020, we had processed 669 loan applications for the SBA Paycheck Protection Program (“PPP loans”), representing a total of $133.9 million. We remain ready to continue to fund eligible client requests through the remaining time period approved by Congress.

President and Chief Executive Officer Jim Eccher said “I want to thank our employees for their dedication and hard work under extremely difficult circumstances over the past several months. Their efforts to promote the safe operation of the Bank while continuing to meet the financial needs of our communities has been nothing short of extraordinary. Old Second remains committed to providing the resources to allow for the safest experience possible for our customers and employees while we continue to work with our customers who have been directly impacted by the pandemic.”

​

Eccher continued, “The credit environment remains uncertain given the economic damage resulting from the pandemic. Recent economic data and decisive government action provide some basis for optimism but significant uncertainty remains regarding the ultimate impact of the pandemic on the local, national and global economies. I believe Old Second is well positioned to capitalize upon opportunities with substantial capital flexibility and strong liquidity. Bottom line results this quarter were strong in the context of the economy and significantly lower interest rates across all maturities. Old Second earned $9.2 million despite adding an additional $2.1 million to the loss reserve for loans and unfunded commitments during the quarter. Deposit growth was excellent and spread income trends held up well despite a decline in the margin resulting from our participation in the Paycheck Protection Program and a large increase in liquidity.”

Asset Quality & Earning Assets

​

| ● | Nonperforming loans totaled $20.2 million at June 30, 2020, compared to $21.8 million at March 31, 2020, and $12.7 million at June 30, 2019. Credit metrics continue to be relatively stable regarding nonperforming loan levels, and management is carefully monitoring loans considered to be in a classified status. Nonperforming loans, as a percent of total loans were 1.0% at June 30, 2020, compared to 1.1% at March 31, 2020, and 0.7% at June 30, 2019. Our adoption of CECL on January 1, 2020, resulted in a change in the accounting for purchased credit impaired (“PCI”) loans, which are now considered purchased credit deteriorated (“PCD”) loans under CECL. Prior to January 1, 2020, past due and nonaccrual loan excluded PCI loans, even if contractually past due or if we did not expect to receive payment in full, as we were accreting interest income over the expected life of the loans. PCD loans acquired in our acquisition of ABC Bank totaled $11.1 million, net of purchase accounting adjustments, at June 30, 2020. PCD loans that meet the definition of nonperforming are now included in nonperforming disclosures.

| ● | OREO assets totaled $5.1 million at June 30, 2020, compared to $5.0 million at March 31, 2020, and $5.7 million at June 30, 2019. We recorded write-downs of $60,000 in the second quarter of 2020, compared to $158,000 in the first quarter of 2020 and $196,000 in the second quarter of 2019. Nonperforming assets, as a percent of total loans plus OREO, were 1.2% at June 30, 2020, 1.4% at March 31, 2020, and 1.0% June 30, 2019.

| ● | Total loans were $2.05 billion at June 30, 2020, reflecting an increase of $95.1 million compared to March 31, 2020, and an increase of $149.4 million compared to June 30, 2019. Growth in the year over year period was due primarily to an increase in our commercial portfolio stemming from PPP loan originations of $133.9 million, as well as organic growth in our leases and real estate-commercial portfolios. Average loans (including loans held-for-sale) for the second quarter of 2020 were $2.05 billion, reflecting an increase of $106.8 million from the first quarter of 2020 and an increase of $154.8 million from the second quarter of 2019.

| ● | Available-for-sale securities totaled $447.4 million at June 30, 2020, compared to $449.7 million at March 31, 2020, and $492.1 million at June 30, 2019. Total securities available-for-sale decreased $2.3 million from the linked quarter due to maturities and paydowns of $19.4 million, purchases of $6.7 million and unrealized mark to market gains of $11.0 million. A decline of $44.6 million was realized in the year over year quarter due primarily to security maturities and paydowns recorded in the third quarter of 2019 and first quarter of 2020.

1 Tax equivalent (TE) basis is calculated using a marginal tax rate of 21% in 2020 and 2019. See the discussion entitled “Non-GAAP Presentations” below and the table on page 17 that provides a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

2 Interest income from loans is shown on a tax equivalent basis, which is a non-GAAP financial measure as discussed in the table on page 17, and includes fees of $718,000 for the second quarter of 2020, $294,000 for the first quarter of 2020, and $184,000 for the second quarter of 2019. Nonaccrual loans are included in the above stated average balances.

Net interest income (TE) was $23.1 million for the second quarter of 2020, which reflects a decrease of $33,000 compared to the first quarter of 2020, and a decrease of $2.2 million compared to the second quarter of 2019. The tax equivalent adjustment for the second quarter of 2020 was $374,000, compared to $390,000 for the first quarter of 2020, and $572,000 for the second quarter of 2019. Average interest earning assets increased $209.2 million to $2.67 billion for the second quarter of 2020, compared to the first quarter of 2020, primarily due to PPP loan growth. Average interest earning assets increased $220.5 million in the second quarter of 2020, compared to the second quarter of 2019. Average loans, including loans held-for-sale, increased $106.8 million for the second quarter of 2020, compared to the first quarter of 2020, and increased $154.7 million compared to the second quarter of 2019. Growth in volumes of earning assets for the second quarter of 2020, compared to the first quarter of 2020 and the second quarter of 2019, was more than offset

by a decline in yields. The yield on average earning assets decreased 62 basis points in the second quarter of 2020, compared to the first quarter of 2020, and decreased 101 basis points compared to the second quarter of 2019, primarily due to the lowering of interest rates by the Federal Reserve in the first quarter of 2020 in response to the COVID-19 pandemic, $133.9 million of PPP loans issued at 1.00% in the second quarter of 2020, and interest rate reductions in the second half of 2019.

Total securities income was $3.5 million in the second quarter of 2020, a decrease of $544,000 compared to the first quarter of 2020, and a decrease of $1.5 million compared to the second quarter of 2019, due primarily to reductions in yields and volumes. Security sales and paydowns in the second quarter of 2020 totaled $19.4 million, which were partially offset by a $6.7 million purchase of a tax anticipation warrant. Our overall yield on tax equivalent municipal securities was 3.47% for the second quarter of 2020, compared to 3.66% for the first quarter of 2020, and 3.74% for the second quarter of 2019. Taxable security yields also declined in the second quarter of 2020, resulting in a decrease to the overall tax equivalent yield for the total securities portfolio of 32 basis points from March 31, 2020, and 73 basis points from June 30, 2019.

Average interest bearing liabilities increased $36.2 million in the second quarter of 2020, compared to the first quarter of 2020, driven by a $62.5 million increase in average interest bearing deposits, and partially offset by a $14.7 million decrease in average short-term borrowings and a $21.4 million decrease in average junior subordinated debentures. Average interest bearing liabilities decreased $32.8 million in the second quarter of 2020, compared to the second quarter of 2019, primarily driven by an $85.0 million decrease in other short-term borrowings, and a $31.9 million decrease in junior subordinated debentures, partially offset by a $68.8 million increase in interest bearing deposits. The cost of interest bearing liabilities for the second quarter of 2020 decreased by 45 basis points from the first quarter of 2020, and decreased 41 basis points from the second quarter of 2019. Growth in our average noninterest bearing demand deposits of $208.7 million in the year over year quarter has assisted us in controlling our cost of funds stemming from average interest bearing deposits, which totaled 0.48% for the second quarter of 2020, and 0.66% for both the first quarter of 2020 and the second quarter of 2019.

​

For the second quarter of 2020, average other short-term borrowings, which consisted solely of FHLBC advances, totaled $8.4 million, compared to $23.1 million for the first quarter of 2020, and $93.4 million for the second quarter of 2019. Average rates paid on short-term FHLBC advances decreased from 2.47% in the second quarter of 2019 to 1.90% in the first quarter of 2020, and to 1.63% in the second quarter of 2020, reflecting the falling interest rate environment. In March 2020, we redeemed our trust preferred securities issued by Old Second Capital Trust I and related junior subordinated debentures, which resulted in a payment of $33.0 million, including accrued interest. The redemption was funded with cash on hand and a $20.0 million term note issued at one month Libor plus 1.75%, with principal and interest payable over the next three years, included within notes payable and other borrowings. Due to the redemption, we recognized the remaining unamortized deferred issuance costs of $635,000 recorded on the junior subordinated debentures in March 2020, increasing our cost of funds by 15 basis points for the first quarter of 2020.

​

Our net interest margin (TE) decreased 29 basis points to 3.48% for the second quarter of 2020, compared to 3.77% for the first quarter of 2020, and decreased 67 basis points compared to 4.15% for the second quarter of 2019. Our core net interest margin (TE), a non-GAAP financial measure that excludes the impact of our PPP loans, was 3.51% for the second quarter of 2020, compared to 3.77% and 4.15% for the first quarter of 2020 and second quarter of 2019, respectively. The reductions were due primarily to falling interest rates and the redemption of our junior subordinated debentures late in the first quarter of 2020, noted above. See the discussion entitled “Non-GAAP Presentations” in the table on page 17 that provides a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Noninterest income increased $4.4 million, or 69.2%, in the second quarter of 2020, compared to the first quarter of 2020, and increased $2.6 million, or 31.3%, compared to the second quarter of 2019. These increases were primarily driven by $4.6 million in net gain on sales of mortgage loans and a reduction in the mark to market losses on MSRs in the second quarter of 2020, compared to both the prior quarter and year over year quarter. The cash surrender value of BOLI increased in the second quarter of 2020 by $581,000 compared to the first quarter of 2020, and increased $212,000 compared to the second quarter of 2019.

The noted increases were partially offset by a reduction in service charges on deposits, as overdraft and bounce fees declined due to a decrease in customer transactional activity as a result of the COVID-19 pandemic, resulting in a decrease of $606,000 in the second quarter of 2020, compared to the linked quarter, and a decrease of $839,000 year over year. The year over year increase in noninterest income was also offset by a $986,000 decrease in securities gains, net, and a $241,000 decrease in card related income.

1 The efficiency ratio shown in the table above is a GAAP financial measure calculated as noninterest expense, excluding amortization of core deposits and OREO expenses, divided by the sum of net interest income and total noninterest income less any BOLI death benefit recorded, net gains or losses on securities and mark to market gains or losses on MSRs.

2 The adjusted efficiency ratio shown in the table above is a non-GAAP financial measure calculated as noninterest expense, excluding amortization of core deposits and OREO expenses, divided by the sum of net interest income on a fully tax equivalent basis, total noninterest income less net gains or losses on securities and mark to market gains or losses on MSRs, and includes a tax equivalent adjustment on the change in cash surrender value of BOLI. See the discussion entitled “Non-GAAP Presentations” below and the table on page 17 that provides a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.

Noninterest expense for the second quarter of 2020 decreased $2.1 million, or 10.0%, compared to the first quarter of 2020, and decreased $1.2 million, or 6.1%, compared to the second quarter of 2019. The linked quarter decrease is primarily attributable to a $1.6 million decrease in salaries and employee benefits stemming from an increase in deferrals of new loan origination costs related to PPP loans, a $366,000 decrease in occupancy, furniture and equipment expense, a $98,000 decrease in other real estate owned expense primarily due to valuation write-downs on properties in the first quarter of 2020, and a $52,000 reduction in advertising expense. These reductions were partially offset by an increase of $98,000 in FDIC insurance and $45,000 in legal fees.

The year over year decrease in noninterest expense is primarily attributable to a $245,000 decrease in salaries and employee benefits, a $277,000 decrease in computer and data processing expense, a $324,000 decrease in advertising expense, a $105,000 decrease in other real estate owned expense due to property valuation write-downs, and a $305,000 decrease in other expense. The decrease in other expense was mainly attributable to reductions in consulting and management fees and other marketing expenses. Partially offsetting the year over year decreases was a $39,000 increase in FDIC insurance and a $40,000 increase in card related expense.

2 As a result of our adoption of the new CECL accounting standard effective January 1, 2020, loans formerly referred to as PCI loans are considered PCD loans under CECL for all periods presented after December 31, 2019, and are included in the amounts above based on loan type.

​

Total loans increased by $95.1 million at June 30, 2020, compared to March 31, 2020, and increased $149.4 million for the year over year period. Growth in the year over year period was primarily due to PPP loan originations of $133.9 million, recorded within commercial loans, as well as organic growth in our commercial, leases and commercial real estate-investor loan portfolios. As required by CECL, the balance (or amortized cost basis) of PCD loans are carried on a gross basis (rather than net of the associated credit loss estimate), and the expected credit losses for PCD loans are estimated and separately recognized as part of the allowance for credit losses. Accordingly, at January 1, 2020, $2.5 million of purchase accounting adjustments related to PCD loans were reclassified to the allowance for credit losses from loans, resulting in an increase to total PCD loans.

Our securities portfolio totaled $447.4 million as of June 30, 2020, a decrease of $2.3 million from $449.7 million as of March 31, 2020, and a decrease of $44.6 million from June 30, 2019. The decrease in the portfolio during the second quarter of 2020 was due to $19.4 million of security maturities and paydowns, partially offset by unrealized mark to market gains of $11.0 million, as well as a $6.7 million tax anticipation warrant purchase. No security sales were recorded in the second quarter of 2020; $24,000 of net security losses were recorded in the first quarter of 2019, and $986,000 of net security gains were recorded in the second quarter of 2019.

1 In 2020, due to the adoption of CECL, PCD loans are included in total nonperforming assets, if their risk rating at period end so indicates. For 2019 periods presented, PCI loans are not included within total nonperforming assets as these loans had an accretable yield.

​

Nonperforming loans consist of nonaccrual loans, performing troubled debt restructured loans accruing interest and loans 90 days or more past due and still accruing interest. We historically excluded PCI loans meeting nonperforming criteria from our nonperforming disclosures as long as their cash flows and the timing of such cash flows continued to be estimable and probable of collection. As a result of CECL implementation on January 1, 2020, PCI loans became PCD loans. PCD loans that meet the definition of nonperforming are now included in our nonperforming disclosures. Nonperforming loans to total loans was 1.0% for the second quarter of 2020, 1.1% for the first quarter of 2020, and 0.7% for the second quarter of 2019. Nonperforming assets to total loans plus OREO remained relatively stable and ended at 1.2% for the second quarter of 2020, compared to 1.4% for the first quarter of 2020, and 1.0% for the second quarter of 2019, as our loan portfolio grew year over year, and we continued OREO liquidations and recorded write-downs. Our allowance for credit losses to total loans was 1.5% as of both June 30, 2020 and March 31, 2020, and 1.0% as of June 30, 2019.

​

2 For purposes of this table, for the three months ended June 30, 2019, classified loan amounts excluded $10.8 million of PCD loans, net of purchase accounting adjustments, formerly purchased credit impaired loans, even if contractually past due or if we did not expect to receive payment in full, as we were accreting interest income over the expected life of the loans.

​

Classified loans include nonaccrual, performing troubled debt restructurings, PCD loans (formerly PCI loans, as applicable), and all other loans considered substandard. Classified loans totaled $39.5 million as of June 30, 2020, a decrease of $4.5 million, or 10.2%, from the prior linked quarter, and a decrease of $7.2 million, or 15.4%, from the second quarter of 2019. All PCD loans stem from our acquisition of ABC Bank in 2018.

​

Allowance for Credit Losses on Loans and Unfunded Commitments

​

At June 30, 2020, our allowance for credit losses (“ACL”) on loans totaled $31.3 million, and our ACL on unfunded commitments, included in other liabilities, totaled $5.0 million. This increased ACL from year-end 2019 was driven by the $8.0 million of provision expense in the first quarter of 2020, and by the adoption of CECL on January 1, 2020, in which we recognized an increase in our ACL on outstanding loans of $5.9 million and an increase in our ACL on unfunded commitments of $1.7 million as a cumulative effect adjustment from change in accounting policies. During the second quarter of 2020, we recorded $1.4 million of ACL related to loans, and $734,000 of additional ACL related to unfunded commitments. The growth in the ACL for unfunded commitments in the second quarter of 2020, compared to the prior quarter, was primarily related to commercial unfunded commitments, with an increase in the funding rate assumptions based on our analysis of the last 12 months of utilization. The total increase in the ACL during 2020 reflects forecasted credit deterioration due to the COVID-19 pandemic and the resultant recession. Our ACL on loans to total loans was 1.5% as of both June 30, 2020 and March 31, 2020, compared to 1.0% at both December 31, 2019 and June 30, 2019. The ACL on unfunded commitments totaled $5.0 million as of June 30, 2020, compared to $4.2 million as of March 31, 2020.

​

Gross charge-offs for the second quarter of 2020 were $406,000, compared to $1.4 million for the first quarter of 2020, and $474,000 for the second quarter of 2019. Gross recoveries were $239,000 for the second quarter of 2020, compared to $279,000 for the first quarter of 2020 and $80,000 for the second quarter of 2019. Continued recoveries are indicative of the ongoing aggressive efforts by management to effectively manage and resolve prior charge-offs.

​

Deposits

​

Total deposits were $2.45 billion at June 30, 2020, an increase of $255.7 million compared to March 31, 2020, resulting from net increases in demand deposits of $188.0 million, savings, NOW and money market accounts of $89.7 million, partially offset by a decrease in time deposits of $22.1 million. Total deposits increased $373.5 million in the year over year period driven primarily by growth in demand deposits of $257.7 million, and savings, NOW and money market accounts of $109.7 million.

​

Borrowings

​

As of June 30, 2020, we had $8.3 million in other short-term borrowings compared to $6.4 million as of March 31, 2020, and $87.1 million as of June 30, 2019. Due to growth in deposits, our need for short-term funding in 2020 has declined year over year.

​

We are indebted on senior notes totaling $44.3 million, net of deferred issuance costs, as of June 30, 2020. We are also indebted on $25.8 million of junior subordinated debentures, net of deferred issuance costs, which is related to the trust preferred securities issued by our statutory trust subsidiary, Old Second Capital Trust II. On March 2, 2020, we redeemed the trust preferred securities issued by Old Second Capital Trust I and related junior subordinated debentures, which resulted in a decrease in junior subordinated debentures of $32.0 million. Notes payable and other borrowings totaled $25.5 million as of June 30, 2020, and is comprised of $19.0 million outstanding on a $20.0 million term note we originated to facilitate the redemption of our trust preferred securities issued by Old Second Capital Trust I and related junior subordinated debentures, and $6.5 million of a long-term FHLBC advance acquired in our ABC Bank acquisition that matures on February 2, 2026.

Non-GAAP Presentations: Management has disclosed in this earnings release certain non-GAAP financial measures to evaluate and measure our performance, including the presentation of net interest income and net interest margin on a fully taxable equivalent basis, our efficiency ratio calculations and core net interest margin on a taxable equivalent basis. The net interest margin fully taxable equivalent is calculated by dividing net interest income on a tax equivalent basis by average earning assets for the period. Management believes this measure provides investors with information regarding balance sheet profitability. Consistent with industry practice, management has disclosed the efficiency ratio including and excluding certain items, which is discussed in the noninterest expense presentation on page 7. Our core net interest margin on a taxable equivalent basis excludes the impact of our PPP loans. These non-GAAP financial

11

measures should not be considered as a substitute for GAAP financial measures, and we strongly encourage investors to review the GAAP financial measures included in this earnings release and not to place undue reliance upon any single financial measure. In addition, because non-GAAP financial measures are not standardized, it may not be possible to compare the non-GAAP financial measures presented in this earnings release with other companies’ non-GAAP financial measures having the same or similar names. The tables on page 17 provide a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.
