Old Second Reports Fourth Quarter Net Income of $8.0 million, or $0.27 per Diluted Share

​

AURORA, IL, January 27, 2021 – 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 fourth quarter of 2020. Our net income was $8.0 million, or $0.27 per diluted share, for the fourth quarter of 2020, compared to net income of $10.3 million, or $0.34 per diluted share, for the third quarter of 2020, and net income of $9.5 million, or $0.31 per diluted share, for the fourth quarter of 2019. Net income for the fourth quarter of 2020 reflects a decrease in noninterest income year over year primarily due to an increase in mark to market losses on mortgage servicing rights (“MSRs”), a reduction in service charges on deposits stemming from a decline in customer spending during the COVID-19 pandemic, a decrease in the death benefit realized on BOLI, as a death claim of $872,000 was received in the prior year period which was not repeated in the current period, and an increase in noninterest expense of $1.4 million, primarily driven by growth in salaries and employee benefits expense. Partially offsetting this reduction to fourth quarter net income year over year was an increase in net interest income due to loan fees recorded on forgiven SBA Paycheck Protection Program (“PPP”) loans and a decrease in interest expense on deposits due to market interest rate reductions. In addition, growth in mortgage banking income due to an increase in mortgage originations and refinances stemming from the low interest rate environment contributed a positive $1.0 million pretax, or $0.03 per diluted share.

Operating Results

●Fourth quarter 2020 net income was $8.0 million, reflecting a decrease in earnings of $2.2 million from the third quarter of 2020, and a decrease in earnings of $1.5 million from the fourth quarter of 2019.
●Net interest and dividend income was $23.9 million for the fourth quarter of 2020, an increase of $1.4 million, or 6.1%, from the third quarter of 2020, and an increase of $688,000, or 3.0%, from fourth quarter of 2019. Net interest and dividend income in the year over year period was favorably impacted by loan fees earned on forgiven PPP loans during the fourth quarter of 2020, as well as a reduction in interest expense due to a decrease in market interest rates. We originated 746 PPP loans totaling $136.7 million in 2020, and as of December 31, 2020, $74.1 million on 428 PPP loans remains outstanding. Net loan fee income recorded year to date on PPP loans totaled $2.2 million, and approximately $420,000 of net PPP loan fees remain unearned as of December 31, 2020.
●We recorded no provision for credit losses in the fourth quarter of 2020, compared to $300,000 in the third quarter of 2020, both under the current expected credit losses accounting standard (“CECL”), which was adopted on January 1, 2020, and considers potential credit losses related to the ongoing COVID-19 pandemic, compared to $150,000 in the fourth quarter of 2019, under the incurred loss model. Allowance for credit losses on loans activity in the fourth quarter of 2020 consisted of a reclassification from the allowance on unfunded commitments of $993,000, as well as $55,000 of net charge-off activity for the quarter.
●Noninterest income was $8.8 million for the fourth quarter of 2020, a decrease of $2.9 million, or 24.8%, compared to $11.7 million for the third quarter of 2020, and a decrease of $457,000, or 4.9%, compared to $9.2 million for the fourth quarter of 2019. The decrease from the linked quarter was primarily driven by a $3.1 million decline in residential mortgage banking revenue, attributable to a $1.9 million decrease in net gain on sales of mortgage loans and a $1.1 million increase in mark to market losses on MSRs in the fourth quarter of 2020, compared to the prior quarter. The decrease in noninterest income in the fourth qu a rter of 2020, compared to the fourth quarter of 2019, was primarily due to a $1.5 million increase in mark to market losses on MSRs, a $530,000 reduction in service charges on deposits, and an $872,000 reduction in death benefit realized on

BOLI. These year over year declines were materially offset by a net $1.0 million increase in residential mortgage banking revenue, primarily comprised of a $2.3 million increase in net gain on sales of mortgage loans and a $236,000 increase in secondary mortgage fees in the fourth quarter of 2020, compared to the fourth quarter of 2019.

| ● | Noninterest expense was $21.3 million for the fourth quarter of 2020, an increase of $987,000, or 4.9%, compared to $20.3 million for the third quarter of 2020, and an increase of $1.4 million, or 7.2%, from $19.8 million for the fourth quarter of 2019. The increase compared to the linked quarter was primarily attributable to an increase in salaries stemming from a decrease in deferrals of new loan origination costs related to PPP loans, growth in occupancy, furniture and equipment costs due to scheduled building repairs, and increases in other expense, which included losses due to fraud and an ATM robbery in the fourth quarter of 2020, as well as an increase in loan related costs, such as appraisals and loan servicing expense. The increase compared to the year over year period was primarily attributable to increases in salaries and employee benefits largely resulting from growth in full time equivalent employees, increases in employee insurance costs, and annual employee merit increases in early 2020, as well as increases in FDIC insurance costs, as 2019’s expense for this item reflected assessment credits.

| ● | The provision for income taxes expense was $3.4 million for the fourth quarter of 2020, compared to $3.4 million for the third quarter of 2020, and $2.9 million for the fourth quarter of 2019. The increase in tax expense for the year over year period was due to year-end adjustments to record select disallowed items for our 2020 tax return, such as employee parking expenses, and a true up for the prior year’s tax return filed.

| ● | During the fourth quarter of 2020, we repurchased 122,862 shares of our common stock at a weighted average price of $9.10 per share pursuant to our stock repurchase program.

| ● | On January 19, 2021, our Board of Directors declared a cash dividend of $0.01 per share payable on February 8, 2021, to stockholders of record as of January 29, 2021.

COVID-19 Operational Update

During this unprecedented time, the health and safety of our customers and employees remains 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.

| ● | Late in the first quarter of 2020, we began granting loan payment deferrals to certain borrowers affected by the pandemic. As of December 31, 2020, our clients had requested loan payment deferrals on 499 loans totaling $231.3 million. As of December 31, 2020, 448 loans, representing $198.6 million outstanding, or 85.8% of the original loan balances deferred, have resumed payments or paid off. Active payment deferrals remain on 51 loans, with $32.7 million of balances outstanding.

| ● | We are participating in the Coronavirus Aid, Relief and Economic Security Act (“CARES” Act). During 2020, we processed 746 loan applications for the PPP loans, representing a total of $136.7 million. Early in the fourth quarter of 2020, we started to submit applications for PPP loan forgiveness to the SBA, and as of year-end 2020, $62.6 million on 318 loans has been forgiven. We anticipate receiving funds for PPP loan forgiveness from the SBA through the first quarter of 2021.

President and Chief Executive Officer Jim Eccher said "I’m proud of the year Old Second had in 2020 amid the many challenges of the pandemic. We posted solid financial results, grew loans and deposits, delivered positive operating leverage, and significantly strengthened our capital position. Despite this performance, net income declined as we built substantial reserves to address the possibility of losses based on probability weighted economic scenarios and stresses created by the pandemic. These losses may or may not occur at the severity levels our models predict. Regardless, I believe Old Second is conservatively positioned to meet challenges as they occur. Expenses are well controlled, our businesses are well diversified and underwriting has remained disciplined and consistent. I would like to thank our employees for their continued hard work in delivering a solid year and in meeting the needs of our customers and communities during these challenging times.”

Asset Quality & Earning Assets

​

| ● | Nonperforming loans totaled $23.0 million at December 31, 2020, compared to $20.8 million at September 30, 2020, and $15.8 million at December 31, 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 1.1% at December 31, 2020, 1.0% at September 30, 2020 and 0.8% at December 31, 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 loans 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 $10.9 million, net of purchase accounting adjustments, at December 31, 2020. PCD loans that meet the definition of nonperforming are now included in our nonperforming disclosures.

| ● | OREO assets totaled $2.5 million at December 31, 2020, compared to $2.7 million at September 30, 2020, and $5.0 million at December 31, 2019. We recorded write-downs of $93,000 in the fourth quarter of 2020, compared to $46,000 in the third quarter of 2020 and $120,000 in the fourth quarter of 2020. Nonperforming assets, as a percent of total loans plus OREO, were 1.3% at December 31, 2020, 1.2% at September 30, 2020, and 1.1% at December 31, 2019.

| ● | Total loans were $2.03 billion at December 31, 2020, reflecting an increase of $4.5 million compared to September 30, 2020, and $104.0 million compared to December 31, 2019. Growth in the year over year period was due primarily to an increase in our commercial portfolio stemming from PPP loan originations of $136.7 million, $74.1 million of which were outstanding at year end 2020, as well as organic growth primarily in our leases, commercial real estate-investor and construction portfolios. Average loans (including loans held-for-sale) for the fourth quarter of 2020 totaled $2.03 billion, reflecting a decrease of $16.2 million from the third quarter of 2020 and an increase of $129.5 million from the fourth quarter of 2019.

| ● | Available-for-sale securities totaled $496.2 million at December 31, 2020, compared to $448.4 million at September 30, 2020, and $484.6 million at December 31, 2019. Total securities available-for-sale increased a net $47.8 million from the linked quarter due to a purchase of $50.5 million of asset backed securities and unrealized mark to market gains of $4.2 million, offset by $6.4 million of securities calls, maturities and paydowns. An increase in available for sale securities of $11.5 million was realized in the year over year period due primarily to purchases of $65.2 million and unrealized mark to market gains of $14.7 million

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 16 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 16, and includes fees of $2.3 million for the fourth quarter 2020, $975,000 for the third quarter of 2020, and $397,000 for the fourth quarter of 2019. Nonaccrual loans are included in the above stated average balances.

Net interest income (TE) was $24.2 million for the fourth quarter of 2020, which reflects an increase of $1.4 million compared to the third quarter of 2020, and an increase of $642,000 compared to the fourth quarter of 2019. The tax equivalent adjustment for the fourth quarter of 2020 was $347,000, compared to $356,000 for the third quarter of 2020, and $393,000 for the fourth quarter of 2019. Average interest earning assets increased $29.2 million to $2.80 billion for the fourth quarter of 2020, compared to the third quarter of 2020, primarily due to growth in taxable securities available-for-sale. Average interest earning assets increased $373.1 million in the fourth quarter of 2020,

compared to the fourth quarter of 2019, primarily due to growth in interest earning deposits with financial institutions and loans. Average loans, including loans held-for-sale, decreased $16.2 million for the fourth quarter of 2020, compared to the third quarter of 2020, but increased $129.5 million compared to the fourth quarter of 2019. The yields on loans for the fourth quarter of 2020 compared to the third quarter of 2020, increased 22 basis points, primarily due to the loan fees recognized on forgiven PPP loans in the fourth quarter of 2020. Growth in the balance of interest earning deposits and securities for the fourth quarter of 2020, compared to both the third quarter of 2020 and the fourth quarter of 2019, was more than offset by the aggregate impact of the decline in yields on these balances. The yield on average earning assets increased nine basis points in the fourth quarter of 2020, compared to the third quarter of 2020, due to the PPP loan fees noted above, and decreased 85 basis points compared to the fourth 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, and $136.7 million of PPP loans issued at 1.00% in the second and third quarters of 2020.

Total securities income was $3.1 million in the fourth quarter of 2020, a decrease of $43,000 compared to the third quarter of 2020, and a decrease of $1.1 million compared to the fourth quarter of 2019, due primarily to reductions in yields in the linked quarter and a reduction in yields and volume in the year over year period. Security paydowns, maturities and calls in the fourth quarter of 2020 totaled $6.4 million, which were offset by $50.5 million of purchases, primarily in asset backed securities. Our overall yield on tax equivalent municipal securities was 3.36% for the fourth quarter of 2020, compared to 3.40% for the third quarter of 2020, and 3.68% for the fourth quarter of 2019. Taxable security yields also declined in the fourth quarter of 2020, resulting in a decrease to the overall tax equivalent yield for the total securities portfolio of 23 basis points from September 30, 2020, and 86 basis points from December 31, 2019.

Average interest bearing liabilities increased $12.2 million in the fourth quarter of 2020, compared to the third quarter of 2020, driven by a $3.3 million increase in average interest bearing deposits, and a $12.7 million increase in average securities sold under repurchase agreements for the linked quarter. Average interest bearing liabilities increased $111.6 million in the fourth quarter of 2020, compared to the fourth quarter of 2019, primarily driven by a $129.3 million increase in interest bearing deposits, a $21.9 million increase in securities sold under repurchase agreements, and a $15.6 million increase in notes payable and other borrowings, partially offset by a reduction in other short-term borrowings of $23.3 million, and a $32.0 million decrease in junior subordinated debentures. The cost of interest bearing liabilities for the fourth quarter of 2020 decreased by nine basis points from the third quarter of 2020, and decreased 60 basis points from the fourth quarter of 2019. Growth in our average noninterest bearing demand deposits of $225.2 million in the year over year period has assisted us in controlling our cost of funds stemming from average interest bearing deposits and borrowings, which totaled 0.32% for the fourth quarter of 2020, 0.38% for the third quarter of 2020, and 0.77% for the fourth quarter of 2019.

​

For the fourth quarter of 2020, average other short-term borrowings, which consisted solely of FHLBC advances, totaled $5.4 million, compared to $8.2 million for the third quarter of 2020, and $28.8 million for the fourth quarter of 2019. Average rates paid on short-term FHLBC advances decreased from 1.99% in the fourth quarter of 2019 to 1.16% in the third quarter of 2020, and to 0.88% in the fourth quarter of 2020, reflecting the falling interest rate environment. We drew on a $4.0 million zero interest borrowing from the FHLB’s COVID-19 relief program in the second quarter of 2020; these borrowings were available to members for a one year term. The $4.0 million was paid off in the fourth quarter of 2020. The decrease in junior subordinated debentures year over year stems from the March 2020 redemption of 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 2.25 years; $17.0 million of this term note is outstanding and included within notes payable and other borrowings as of December 31, 2020.

​

Our net interest margin increased 16 basis points to 3.39% for the fourth quarter of 2020, compared to 3.23% for the third quarter of 2020, and decreased 40 basis points compared to 3.79% for the fourth quarter of 2019. Our net interest margin (TE) increased 16 basis points to 3.44% for the fourth quarter of 2020, compared to 3.28% for the third quarter of 2020, and decreased 42 basis points compared to 3.86% for the fourth quarter of 2019. Our core net interest margin (TE), a non-GAAP financial measure that excludes the impact of our PPP loans, was 3.32% for the fourth quarter of 2020, compared to 3.34% for the third quarter of 2020 and 3.86% for the fourth quarter of 2019. The net interest margin (TE) increased in the fourth quarter of 2020, compared to the third quarter of 2020, due to the fee income recorded on $62.6 million of forgiven PPP loans in the fourth quarter of 2020. The reductions year over year were due primarily to falling interest rates over the past twelve months. See the discussion entitled “Non-GAAP Presentations” in the table on page 16 that provides a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Noninterest income decreased $2.9 million, or 24.8%, in the fourth quarter of 2020, compared to the third quarter of 2020, and decreased $457,000, or 4.9%, compared to the fourth quarter of 2019. The decrease from the linked quarter was primarily driven by $3.1 million of decline in residential mortgage banking revenue, attributable to a $1.9 million decrease in net gain on sales of mortgage loans and a $1.1 million increase in mark to market losses on MSRs in the fourth quarter of 2020.

The decrease in noninterest income in the fourth quarter of 2020 compared to the fourth quarter of 2019 is primarily due to a $530,000 reduction in service charges on deposits as consumer spending decreased during the COVID-19 pandemic, and a $1.5 million increase in mark to market losses on MSRs from the 2019 like period. In addition, the fourth quarter of 2019 included an $872,000 death benefit realized on BOLI, which was not repeated in the fourth quarter of 2020.

These year over year declines were materially offset by a net $1.0 million increase in residential mortgage banking revenue, primarily comprised of a $2.3 million increase in net gain on sales of mortgage loans and a $236,000 increase in secondary mortgage fees in the fourth quarter of 2020, compared to the fourth quarter of 2019, due to the low interest rate environment and resultant increases in mortgage originations and refinances.

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 16 that provides a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.

Noninterest expense for the fourth quarter of 2020 increased $987,000, or 4.9%, compared to the third quarter of 2020, and increased $1.4 million, or 7.2%, compared to the fourth quarter of 2019. The linked quarter increase is primarily attributable to a $247,000 increase in salaries stemming from an increase in deferrals on new loan origination costs related to PPP loans in the third quarter of 2020, with no like level of deferrals in the fourth quarter of 2020. Benefits expense also increased $156,000 as more insurance claims were processed in the fourth quarter. In addition, occupancy, furniture and equipment expense increased $256,000 in the fourth quarter of 2020 compared to the linked quarter due to planned building repairs at various branches. Other expenses increased due to fraud and robbery losses of $147,000 due to an ATM robbery and wire fraud in the fourth quarter, as well as an increase in loan related costs, such as appraisals and servicing expense.

The year over year increase in noninterest expense is primarily attributable to a $1.1 million increase in salaries and employee benefits due to growth in full-time equivalent employees, annual merit increases in early 2020, and employee insurance and other benefits increases. We also had increases in the year over year period in occupancy, furniture and equipment due to building repairs of $119,000, FDIC insurance of $194,000 due to the assessment credits in the prior year, and other real estate owned expense, net, of $47,000 primarily due to closing costs on property sales in the fourth quarter of 2020. These increases were partially offset by a $180,000 decrease in advertising expense in the fourth quarter of 2020.

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 $4.5 million at December 31, 2020, compared to September 30, 2020, and increased $104.0 million for the year over year period. Growth in the year over year period was primarily due to PPP loan originations of $136.7 million, recorded within commercial loans; $74.1 million of PPP loans are outstanding as of December 31, 2020. In addition, we also had organic growth primarily in our leases, commercial real estate-investor and construction 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 $496.2 million as of December 31, 2020, an increase of $47.8 million from $448.4 million as of September 30, 2020, and an increase of $11.5 million from December 31, 2019. The increase in the portfolio during the fourth quarter of 2020, compared to the prior quarter, was due to purchases of $50.5 million of

asset-backed securities and unrealized mark to market gains of $4.2 million, partially offset by $6.4 million of security calls, maturities and paydowns. The increase in the securities portfolio in the year over year period was primarily due to purchases of $65.2 million in asset backed and state and municipal securities, and unrealized mark to market gains of $14.7 million, partially offset by $66.1 million of calls, maturities and paydowns, and $2.3 million of amortization. No security sales were recorded in the fourth quarter of 2020, net security losses of $1,000 were recorded in the third quarter of 2020, and $35,000 of net security gains were recorded in the fourth quarter of 2019.

1 In 2020, due to the adoption of CECL, PCD loans are now included in total nonperforming assets, if their risk rating at period end so indicates. For December 31, 2019, PCI loans were not included within total nonperforming assets since we were accreting interest income over the expected life of the loans.

​

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 1.1% for the fourth quarter of 2020, 1.0% for the third quarter of 2020, and 0.8% for the fourth quarter of 2019. Nonperforming assets to total loans plus OREO remained stable and ended at 1.3% for the fourth quarter of 2020, 1.2 % for the third quarter of 2020, and 1.1% for the fourth 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 1.7% as of December 31, 2020, compared to 1.6% as of September 30, 2020, and 1.0% as of December 31, 2019, prior to the adoption of CECL.

2 For purposes of this table, as of December 31, 2019, classified loan amounts excluded $8.6 million of PCD loans, net of purchase accounting adjustments, formerly 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.

​

Classified loans include nonaccrual, performing troubled debt restructurings, PCD loans (formerly PCI loans, as applicable), and all other loans considered substandard. Classified loans totaled $42.1 million as of December 31, 2020, a decrease of $602,000, or 1.4%, from the prior linked quarter, and an increase of $441,000, or 1.1%, from the fourth 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 December 31, 2020, our allowance for credit losses (“ACL”) on loans totaled $33.9 million, and our ACL on unfunded commitments, included in other liabilities, totaled $3.0 million. The increase in our ACL from year-end 2019 was driven by the $10.4 million of provision expense recorded year to date in 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 fourth quarter of 2020, we recorded $993,000 of provision on ACL related to loans, and reversed $993,000 of the ACL related to unfunded commitments, resulting in no net change to provision for credit losses. The decline in the ACL for unfunded commitments in the fourth quarter of 2020, compared to the prior quarter, was primarily related to commercial unfunded commitments, with a decrease 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 1.7% as of December 31, 2020, compared to 1.6% as of September 30, 2020, and 1.0% at December 31, 2019. The ACL on unfunded commitments totaled $3.0 million as of December 31, 2020, compared to $4.0 million as of September 30, 2020.

Gross charge-offs for the fourth quarter of 2020 were $810,000, compared to $451,000 for the third quarter of 2020, and $835,000 for the fourth quarter of 2019. Gross recoveries were $755,000 for the fourth quarter of 2020, compared to $816,000 for the third quarter of 2020 and $823,000 for the fourth 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 $2.54 billion at December 31, 2020, an increase of $57.8 million compared to September 30, 2020, resulting from net increases in demand deposits of $20.4 million, savings, NOW and money market accounts of $16.4 million and time deposits of $21.0 million. Total deposits increased $410.3 million in the year over year period driven primarily by growth in demand deposits of $239.7 million, and savings, NOW and money market accounts of $186.8 million, partially offset by a decrease in time deposits of $16.2 million.

​

Borrowings

​

As of December 31, 2020, we had no other short-term borrowings compared to $6.1 million as of September 30, 2020, and $48.5 million as of December 31, 2019. Due to growth in deposits, our need for short-term funding in 2020 has declined year over year.

​

We were indebted on senior notes totaling $44.4 million, net of deferred issuance costs, as of December 31, 2020. We were 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 and related junior subordinated debentures issued by Old Second Capital Trust I, which resulted in a decrease in junior subordinated debentures of $32.0 million. Notes payable and other borrowings totaled $23.4 million as of December 31, 2020, and is comprised of $17.0 million outstanding on a $20.0 million term note we originated to facilitate the redemption of our trust preferred securities and related junior subordinated debentures issued by Old Second Capital Trust I, and $6.4 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. Consistent with industry practice, management has disclosed the efficiency ratio including and excluding certain items, which is discussed in the noninterest expense presentation on pages 6-7. Our core net interest margin on a taxable equivalent basis excludes the impact of our PPP loans.

11

We consider the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or assets that we believe are not indicative of our primary business operating results or by presenting certain metrics on a fully taxable equivalent basis. We believe these measures provide investors with information regarding balance sheet profitability, and we believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing and comparing past, present and future periods.

These non-GAAP financial 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 16 provide a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.
