Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of NBT Bancorp and its wholly-owned subsidiaries, the Bank, NBT Financial and NBT Holdings. Collectively, NBT Bancorp and its subsidiaries are referred to herein as (“the Company”). The interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods in accordance with generally accepted accounting principles in the United States of America (“GAAP”). These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2019 Annual Report on Form 10-K. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. All material intercompany transactions have been eliminated in consolidation. Amounts previously reported in the consolidated financial statements are reclassified whenever necessary to conform to current period presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure and there were none identified.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements.

Allowance for Credit Losses – Loans

Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”) approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). It replaces the incurred loss approach’s threshold that required the recognition of a credit loss when it was probable a loss event was incurred. The allowance for credit losses is a valuation account that is deducted from, or added to, the loans’ amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

Management estimates the allowance balance using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Company historical loss experience was supplemented with peer information when there was insufficient loss data for the Company. Peer selection was based on a review of institutions with comparable loss experience as well as loan yield, bank size, portfolio concentration and geography. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level or term as well as changes in environmental conditions, such as changes in unemployment rates, production metrics, property values, or other relevant factors. Significant management judgment is required at each point in the measurement process.

Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Upon adoption of CECL, management revised the manner in which loans were pooled for similar risk characteristics. Management developed segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined or sub-segmented as needed to ensure loans of similar risk profiles are appropriately pooled.

The following table illustrates the portfolio and class segments for the Company’s loan portfolio in 2020:

The Company offers a variety of commercial loan products. The Company’s underwriting analysis for commercial loans typically includes credit verification, independent appraisals, a review of the borrower’s financial condition and a detailed analysis of the borrower’s underlying cash flows.

Commercial and Industrial (“C&I”) – The Company offers a variety of loan options to meet the specific needs of our C&I customers including term loans, time notes and lines of credit. Such loans are made available to businesses for working capital needs and are typically collateralized by business assets such as equipment, accounts receivable and perishable agricultural products, which are exposed to industry price volatility. To reduce these risks, management also attempts to obtain personal guarantees of the owners or to obtain government loan guarantees to provide further support.

Paycheck Protection Program (“PPP”) – Section 1102 of the CARES Act created the Paycheck Protection Program, a program administered by the Small Business Administration (the “SBA”) to provide loans to small businesses for payroll and other basic expenses during the COVID-19 pandemic. The Company has participated in the PPP as a lender. These loans are eligible to be forgiven if certain conditions are satisfied and are fully guaranteed by the SBA. Additionally, loan payments will also be deferred for six months of the loan. The PPP commenced on April 3, 2020 and is available to qualified borrowers through August 8, 2020, or as long as the appropriated funding is available. No collateral or personal guarantees are required. Neither the government nor lenders are permitted to charge the recipients any fees. The Company began accepting applications from qualified borrowers on April 3, 2020 and as of June 30, 2020 processed approximately 3,000 loans totaling over $547 million in relief.

Commercial Real Estate (“CRE”) – The Company offers CRE loans to finance real estate purchases, refinancing’s, expansions and improvements to commercial and agricultural properties. CRE loans are loans that are secured by liens on the real estate, which may include both owner-occupied and nonowner- occupied properties, such as apartments, commercial structures, health care facilities and other facilities. The Company’s underwriting analysis includes credit verification, independent appraisals, a review of the borrower’s financial condition and a detailed analysis of the borrower’s underlying cash flows. These loans are typically originated in amounts of no more than 80% of the appraised value of the property. Government loan guarantees may be obtained to provide further support for agricultural property.

The Company offers a variety of Consumer loan products including Auto and Other Consumer loans.

Auto – The Company provides both direct and indirect financing of automobiles (“Auto”). The Company maintains relationships with many dealers primarily in the communities that we serve. Through these relationships, the Company primarily finances the purchases of automobiles indirectly through dealer relationships. Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from three to six years, based upon the nature of the collateral and the size of the loan.

Other Consumer – The Other Consumer loan segment consists primarily of specialty lending loans and direct consumer loans. The Company offers unsecured specialty lending consumer loans across a national footprint originated through our relationships with national technology-driven consumer lending companies to finance such things as dental and medical procedures, K-12 tuition, solar energy installations and other consumer purpose loans. Advances of credit through this specialty lending business line are subject to the Company’s underwriting standards including criteria such as FICO score and debt to income thresholds. The Company offers a variety of direct consumer installment loans to finance various personal expenditures. In addition to installment loans, the Company also offers personal lines of credit, overdraft protection, debt consolidation, education and other uses. Consumer installment loans carry a fixed rate of interest with principal repayment terms typically ranging from one to fifteen years, based upon the nature of the collateral and the size of the loan. Consumer installment loans are often secured with collateral consisting of a perfected lien on the asset being purchased or a perfected lien on a consumer’s deposit account. Risk is reduced through underwriting criteria, which include credit verification, appraisals, a review of the borrower’s financial condition and personal cash flows. A security interest, with title insurance when necessary, is taken in the underlying real estate.

Residential loans consist primarily of loans secured by a first or second mortgage on primary residences, home equity loans and lines of credit in first and second lien positions and residential construction loans. We originate adjustable-rate and fixed rate, one-to-four-family residential loans for the construction or purchase of a residential property or the refinancing of a mortgage. These loans are collateralized by properties located in the Company’s market area. Loans on one-to-four-family residential are generally originated in amounts of no more than 85% of the purchase price or appraised value (whichever is lower) or have private mortgage insurance. Mortgage title insurance and hazard insurance are normally required. Construction loans have a unique risk because they are secured by an incomplete dwelling. This risk is reduced through periodic site inspections, including one at each loan draw period. For home equity loans, consumers are able to borrow up to 85% of the equity in their homes and are generally tied to Prime with a ten-year draw followed by a fifteen-year amortization. These loans carry a higher risk than first mortgage residential loans as they are often in a second position with respect to collateral.

For the 2019 disclosures for the allowance for credit losses, the loan portfolio was segmented into the Commercial, Consumer and Residential Real Estate portfolio segments. The Commercial segment was further pooled into three classes: Commercial and Industrial, Commercial Real Estate and Business Banking. The Consumer segment was further pooled into three classes: Indirect Auto, Specialty Lending and Direct. For a description of these portfolio segments’ and classes’ risk characteristics, see Note 5 Allowance for Loan Losses and Credit Quality of Loans to the consolidated financial statements presented in our 2019 Annual Report on Form 10-K.

Historical credit loss experience for both the Company and segment-specific peers provides the basis for the estimation of expected credit losses, where observed credit losses are converted to probability of default rate (“PD”) curves through the use of segment-specific loss given default (“LGD”) risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each asset class, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical PDR curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle.

Using the historical relationship between economic conditions and loan performance, management’s expectation of future loan performance is incorporated using externally developed economic forecasts which are probabilistically weighted to reflect potential forecast inaccuracy and model limitations. These forecasts are applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line, time-based methodology.

The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a quarterly basis, when similar risk characteristics exist. The respective quantitative allowance for each segment is measured using an econometric, discounted PD/LGD modeling methodology in which distinct, segment-specific multi-variate regression models are applied to multiple, probabilistically weighted external economic forecasts. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated interest rate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring (“TDR”) will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company.

After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date. Qualitative considerations include limitations inherent in the quantitative model; trends experienced in nonperforming and delinquent loans; changes in value of underlying collateral; changes in lending policies and procedures; nature and composition of loans; portfolio concentrations that may affect loss experience across one or more components of the portfolio; the experience, ability and depth of lending management and staff; the Company’s credit review system; and the effect of external factors; such as competition, legal and regulatory requirements.

Loans that do not share risk characteristics and meet materiality criteria are evaluated on an individual basis and are excluded from the pooled evaluation. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. If the loan is not collateral dependent, the allowance for credit losses related to individually assessed loans is based on discounted expected cash flows using the loan’s initial effective interest rate. Generally, individually assessed loans are collateral dependent.

A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties is considered to be a TDR. The allowance for credit losses on a TDR is measured using the same method as all other loans held for investment, except that the original interest rate is used to discount the expected cash flows, not the rate specified within the restructuring.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

The Company estimates expected credit losses over the contractual period in which the Company has exposure to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Estimating credit losses on unfunded commitments requires the Bank to consider the following categories of off-balance sheet credit exposure: unfunded commitments to extend credit, unfunded lines of credit, and standby letters of credit. Each of these unfunded commitments is then analyzed for a probability of funding to calculate a probable funding amount. The life of loan loss factor by related portfolio segment from the loan allowance for credit loss calculation is then applied to the probable funding amount to calculate a reserve on unfunded commitments.

Allowance for Credit Losses – Held-to-Maturity (“HTM”) Debt Securities

The Company’s HTM debt securities are also required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics, such as (as applicable): internal or external (third-party) credit score or credit ratings, risk ratings or classification, financial asset type, collateral type, size, effective interest rate, term, geographical location, industry of the borrower, vintage, historical or expected credit loss patterns, and reasonable and supportable forecast periods. Management classifies the HTM portfolio into the following major security types: U.S. government agency or U.S. government sponsored mortgage-backed and collateralized mortgage obligations securities, and state and municipal debt securities.

The mortgage-backed and collateralized mortgage obligations HTM securities are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of no credit losses. Therefore, the Company did not record a credit loss for these securities.

State and municipal bonds carry a Moody’s rating of A to AAA. In addition, the Company has a limited amount of New York state local municipal bonds that are not rated. The estimate of expected credit losses on the HTM portfolio is based on the expected cash flows of each individual CUSIP over its contractual life and considers historical credit loss information, current conditions and reasonable and supportable forecasts. Given the rarity of municipal defaults and losses, the Company utilized Moody’s Municipal Loss Forecast Model as the sole source of municipal default and loss rates which provides decades of data across all municipal sectors and geographies. As with the loan portfolio, cash flows are forecast over a 6-quarter period under various, weighted economic conditions, with a reversion to long-term average economic conditions over a 4-quarter period on a straight-line basis. Management may exercise discretion to make adjustments based on environmental factors. As of March 31, 2020 and June 30, 2020, the Company determined that the expected credit loss on its municipal bond portfolio was de minimis, and therefore, an allowance for credit losses was not recorded.

Allowance for Credit Losses – Available-for Sales (“AFS”) Debt Securities

The impairment model for AFS debt securities differs from the CECL approach utilized by HTM debt securities because AFS debt securities are measured at fair value rather than amortized cost. For AFS debt securities in an unrealized loss position, the Bank first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For debt securities AFS that do not meet the aforementioned criteria, in making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, adverse conditions specifically related to the security, failure of the issuer of the debt security to make scheduled interest or principal payments, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows should be estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.

Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the AFS security is uncollectible or when either of the criteria regarding intent or requirement to sell is met. As of March 31, 2020 and June 30, 2020, the Company determined that the unrealized loss positions in the AFS securities were not the result of credit losses, and therefore, an allowance for credit losses was not recorded.

Accrued Interest Receivable

Upon adoption of CECL on January 1, 2020, the Company made the following elections regarding accrued interest receivable: (1) presented accrued interest receivable balances separately within other assets balance sheet line item; (2) excluded interest receivable that is included in amortized cost of financing receivables from related disclosures requirements and (3) continued our policy to write off accrued interest receivable by reversing interest income. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the amount of such write offs are immaterial. For loans given short-term loan modifications to assist borrowers during the COVID-19 national emergency, this accounting policy would not apply as the length of time between interest recognition and the write-off of uncollectible interest could exceed 120 days. Therefore, the Company estimated an allowance for credit losses for accrued interest receivable related to loans with short-term modifications due to the pandemic. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities.

 

Recently Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and all related subsequent amendments thereto. ASU 2016-13 introduces new guidance that make substantive changes to the accounting for credit losses. ASU 2016-13 introduces the CECL model, which applies to financial assets subject to credit losses and measured at amortized cost, as well as certain off-balance sheet credit exposures. This includes loans, loan commitments, standby letters of credit, net investments in leases recognized by a lessor and HTM debt securities. The CECL model requires an entity to estimate credit losses expected over the life of an exposure, considering information about historical events, current conditions and reasonable and supportable forecasts and is generally expected to result in earlier recognition of credit losses. ASU 2016-13 also modifies certain provisions of the current other-than-temporary impairment model for AFS debt securities. Credit losses on AFS debt securities will be limited to the difference between the security’s amortized cost basis and its fair value and will be recognized through an allowance for credit losses rather than as a direct reduction in amortized cost basis. ASU 2016-13 also provides for a simplified accounting model for purchased financial assets with more than insignificant credit deterioration since their origination. ASU 2016-13 requires expanded disclosures including, but not limited to, (1) information about the methods and assumptions used to estimate expected credit losses, including changes in the factors that influenced management’s estimate and the reasons for those changes, (2) financing receivables and net investment in leases measured at amortized cost, further disaggregation of information about the credit quality of those assets and (3) a rollforward of the allowance for credit losses for HTM and AFS securities. The standard also changes the accounting for purchased credit-impaired debt securities and loans. ASU 2016-13 was effective for the Company on January 1, 2020. Management expects that the CECL model may create more volatility in the level of our allowance for loan losses from quarter to quarter as changes in the level of allowance for loan losses will be dependent upon, among other things, macroeconomic forecasts and conditions, loan portfolio volumes and credit quality.

The Company adopted CECL on January 1, 2020 (“Day 1”) using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net decrease to retained earnings of $4.3 million as of January 1, 2020 for the cumulative effect of adopting ASC 326. The transition adjustment includes a $3.0 million impact due to the allowance for credit losses on loans, $2.8 million impact due to the allowance for credit losses on off-balance sheet credit exposure, and $1.5 million impact to the deferred tax asset. The Company did not record an allowance for HTM debt securities on January 1, 2020 as the amount of credit risk was deemed immaterial. The Company did not record an allowance for credit losses on its AFS debt securities under the newly codified AFS debt security impairment model, as the majority of these securities are government agency-backed securities for which the risk of loss is minimal. Refer to Note 4 Securities and Note 5 Allowance for Credit Losses and Credit Quality of Loans to the Company’s unaudited interim consolidated financial statements included in this Form 10-Q for more information.

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

On March 22, 2020, a statement was issued by the Company’s banking regulators and titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of the recent coronavirus (“COVID-19”) pandemic. Additionally, Section 4013 of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), which was enacted on March 27, 2020, further provides that a qualified loan modification is exempt by law from classification as a troubled debt restructuring as defined by GAAP from the period beginning March 1, 2020 until the earlier of December 31, 2020 or the date that is 60 days after the date on which the national emergency concerning the COVID-19 outbreak declared by the President of the United States under the National Emergencies Act (50 U.S.C. 1601 et seq.) terminates. Accordingly, the Company is offering short-term modifications made in response to COVID-19 to borrowers who are current and otherwise not past due. These include short-term, 180 days or less, modifications in the form of payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are not material. As of June 30, 2020, there were $1.0 billion in loans in modification programs related to COVID-19.

In August 2018, the FASB issued ASU 2018-13, Fair value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair value Measurement. The provisions of ASU 2018-13 modify the disclosure requirements on fair value measurements in ASC 820. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. ASU 2018-13 is effective January 1, 2020. The adoption did not have a material impact on the consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) – Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. ASU 2018-15 amends existing guidance and requires a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize and which costs to expense. ASU 2018-15 is effective for the Company on January 1, 2020. The adoption did not have a material impact on the consolidated financial statements and related disclosures.

Accounting Standards Issued Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The ASU provides temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from LIBOR or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022. The Company is evaluating the impact of adopting the new guidance on the consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. The amendments in this ASU are effective for the Company on January 1, 2021, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans - General (Subtopic 715-20), provides changes to the disclosure requirements for defined benefit plans. The amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments are a result of the disclosure framework project that focuses on improvements to the effectiveness of disclosures in the notes to financial statements. The amendments remove and add certain disclosure requirements. The disclosure requirements being removed relating to public companies are: (1) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, (2) the amount and timing of plan assets expected to be returned to the employer, (3) the 2001 disclosure requirement relating to Japanese Welfare Pension Insurance Law, (4) related party disclosures about the amount of future annual benefits covered by insurance, and (5) the effects of a one-percentage-point change in assumed health care cost trends on the benefit cost and obligation. The disclosure requirements being added relating to public companies are (1) the weighted-average interest crediting rates for cash balance plans, and (2) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. ASU 2018-14 is effective for the Company on January 1, 2021 and early adoption is permitted. The amendments should be applied retrospectively and the Company does not expect the guidance to have a material impact on its disclosures to the consolidated financial statements.

The amortized cost, estimated fair value and unrealized gains (losses) of AFS securities are as follows:

There was no allowance for credit losses on AFS securities as of the quarter ending June 30, 2020.

The components of net realized gains (losses) on the sale of AFS securities are as follows. These amounts were reclassified out of accumulated other comprehensive income (loss) (“AOCI”) and into earnings. There were no sales of AFS securities during the three months ended June 30, 2020 and 2019.

Included in net gains (losses) on AFS securities, the Company recorded gains from calls of approximately $3 thousand and $4 thousand for the six months ended June 30, 2020 and 2019, respectively. There were no recorded gains from calls on AFS securities included in net gains (losses) from sales transactions for the three months ended June 30, 2020 and 2019.

The amortized cost, estimated fair value and unrealized gains (losses) of securities HTM are as follows:

At June 30, 2020 and December 31, 2019, all of the mortgaged-backed HTM securities were comprised of U.S. government agency and Government-sponsored enterprises securities. There was no allowance for credit losses on HTM securities as of June 30, 2020.

Included in net realized gains (losses), the Company recorded gains from calls on HTM securities of approximately $4 thousand for the three and six months ended June 30, 2020. There were no recorded gains from calls on HTM securities included in net realized gains (losses) for the three and six months ended June 30, 2019.

During the three and six months ended June 30, 2020, the Company sold HTM securities with an amortized cost of $1.0 million and resulted in a realized loss of $1 thousand. Due to significant deterioration in the creditworthiness of the issuer of the HTM securities, the circumstances caused the Company to change its intent to hold the HTM securities sold to maturity, which did not affect the Company’s intent to hold the remainder of the HTM portfolio to maturity. There were no sales of HTM securities in the three and six month periods ended June 30, 2019

AFS and HTM securities with amortized costs totaling $1.3 billion at June 30, 2020 and December 31, 2019 were pledged to secure public deposits and for other purposes required or permitted by law. Additionally, at June 30, 2020 and December 31, 2019, AFS and HTM securities with an amortized cost of $249.8 million and $189.8 million, respectively, were pledged as collateral for securities sold under repurchase agreements.

The following tables set forth information with regard to gains and losses on equity securities:

As of June 30, 2020 and December 31, 2019, the carrying value of equity securities without readily determinable fair values was $4.0 million. The Company performed a qualitative assessment to determine whether the investments were impaired and identified no areas of concern as of June 30, 2020 and 2019. There were no impairments, downward or upward adjustments recognized for equity securities without readily determinable fair values during the three and six months ended June 30, 2020 and 2019.

The following tables set forth information with regard to contractual maturities of debt securities at June 30, 2020:
