(c) Other-Than-Temporary Impairment Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio by type and applying the appropriate OTTI model. In determining OTTI for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether any other ‑ ‑ When OTTI occurs, the amount of the OTTI recognized in earnings depends on whether management intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If management intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If management does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, the OTTI on debt securities shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. As of March 31, 2019, the Company’s security portfolio included certain securities which were in an unrealized loss position, and are discussed below.

At March 31, 2019 and December 31, 2018, the Company had approximately $27.2 million and $26.7 million of real estate construction loans, respectively. Of the $27.2 million in real estate construction loans at March 31, 2019, approximately $13.8 million are secured by first mortgages to residential borrowers while approximately $13.4 million were to commercial borrowers for residential construction projects. Of the $26.7 million in real estate construction loans at December 31, 2018, approximately $14.2 million are secured by first mortgages to residential borrowers while approximately $12.5 million were to commercial borrowers for residential construction projects. The vast majority of construction loans are in the Company’s New York market. The Company lends in the geographic territory of its branch locations in New York, Florida, Massachusetts, New Jersey and Vermont. Although the loan portfolio is diversified, a portion of its debtors’ ability to repay depends significantly on the economic conditions prevailing in the respective geographic territory. The following tables present the recorded investment in non-accrual loans by loan class: March 31, 2019 (dollars in thousands) New York and other states* Florida Total Loans in non-accrual status: Commercial: Commercial real estate $ 696 - 696 Other 5 - 5 Real estate mortgage - 1 to 4 family: First mortgages 18,282 1,542 19,824 Home equity loans 363 - 363 Home equity lines of credit 3,698 102 3,800 Installment 26 - 26 Total non-accrual loans 23,070 1,644 24,714 Restructured real estate mortgages - 1 to 4 family 33 - 33 Total nonperforming loans $ 23,103 1,644 24,747 December 31, 2018 (dollars in thousands) New York and other states* Florida Total Loans in non-accrual status: Commercial: Commercial real estate $ 639 - 639 Other 6 - 6 Real estate mortgage - 1 to 4 family: First mortgages 18,202 1,812 20,014 Home equity loans 247 - 247 Home equity lines of credit 3,924 103 4,027 Installment 4 15 19 Total non-accrual loans 23,022 1,930 24,952 Restructured real estate mortgages - 1 to 4 family 34 - 34 Total nonperforming loans $ 23,056 1,930 24,986 * Includes New York, New Jersey, Vermont and Massachusetts. The Company transfers loans to other real estate owned, at fair value less cost to sell, in the period the Company obtains physical possession of the property (through legal title or through a deed in lieu). As of March 31, 2019 and December 31, 2018, other real estate owned included $703 thousand and $1.1 million of residential foreclosed properties, respectively. In addition, non-accrual residential mortgage loans that are in the process of foreclosure had a recorded investment of $12.4 million as of March 31, 2019 and December 31, 2018.

At March 31, 2019 and December 31, 2018, there were no loans that were 90 days past due and still accruing interest. As a result, non-accrual loans include all loans 90 days or more past due as well as certain loans less than 90 days past due that were placed on non-accrual status for reasons other than delinquent status. There are no commitments to extend further credit on non-accrual or restructured loans. Activity in the allowance for loan losses by portfolio segment is summarized as follows: For the three months ended March 31, 2019 (dollars in thousands) Commercial Real Estate Mortgage- 1 to 4 Family Installment Total Balance at beginning of period $ 4,048 39,772 946 44,766 Loans charged off: New York and other states* 7 392 29 428 Florida - 29 31 60 Total loan chargeoffss 7 421 60 488 Recoveries of loans previously charged off: New York and other states* 3 74 6 83 Florida - 10 - 10 Total recoveries 3 84 6 93 Net loans charged off 4 337 54 395 Provision for loan losses (310 ) 550 60 300 Balance at end of period $ 3,734 39,985 952 44,671 For the three months ended March 31, 2018 (dollars in thousands) Commercial Real Estate Mortgage- 1 to 4 Family Installment Total Balance at beginning of period $ 4,324 39,077 769 44,170 Loans charged off: New York and other states* - 131 71 202 Florida - - 3 3 Total loan chargeoffs - 131 74 205 Recoveries of loans previously charged off: New York and other states* 6 103 6 115 Florida - - - - Total recoveries 6 103 6 115 Net loans charged off (recoveries) (6 ) 28 68 90 Provision for loan losses (75 ) 310 64 300 Balance at end of period $ 4,255 39,359 765 44,379 * Includes New York, New Jersey, Vermont and Massachusetts. The Company has identified non-accrual commercial and commercial real estate loans, as well as all loans restructured under a troubled debt restructuring (“TDR”), as impaired loans. A loan is considered impaired when it is probable that the borrower will be unable to repay the loan according to the original contractual terms of the loan agreement or the loan is restructured as a TDR. The following tables present the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method as of March 31, 2019 and December 31, 2018: March 31, 2019 (dollars in thousands) Commercial Loans 1-to-4 Family Residential Real Estate Installment Loans Total Allowance for loan losses: Ending allowance balance attributable to loans: Individually evaluated for impairment $ - - - - Collectively evaluated for impairment 3,734 39,985 952 44,671 Total ending allowance balance $ 3,734 39,985 952 44,671 Loans: Individually evaluated for impairment $ 1,467 19,694 - 21,161 Collectively evaluated for impairment 188,880 3,638,533 12,579 3,839,992 Total ending loans balance $ 190,347 3,658,227 12,579 3,861,153 December 31, 2018 (dollars in thousands) Commercial Loans 1-to-4 Family Residential Real Estate Installment Loans Total Allowance for loan losses: Ending allowance balance attributable to loans: Individually evaluated for impairment $ - - - - Collectively evaluated for impairment 4,048 39,772 946 44,766 Total ending allowance balance $ 4,048 39,772 946 44,766 Loans: Individually evaluated for impairment $ 1,424 20,864 - 22,288 Collectively evaluated for impairment 194,722 3,645,384 11,702 3,851,808 Total ending loans balance $ 196,146 3,666,248 11,702 3,874,096 A loan for which the terms have been modified, and for which the borrower is experiencing financial difficulties, is considered a TDR and is classified as impaired. TDR’s at March 31, 2019 and December 31, 2018 are measured at the present value of estimated future cash flows using the loan’s effective rate at inception or the fair value of the underlying collateral if the loan is considered collateral dependent.

The Company has not committed to lend additional amounts to customers with outstanding loans that are classified as impaired. Interest income recognized on impaired loans was not material during the three months ended March 31, 2019 and 2018. As of March 31, 2019 and December 31, 2018 impaired loans included approximately $10.9 million and $11.1 million of loans in accruing status that were identified as TDR’s in accordance with regulatory guidance related to Chapter 7 bankruptcy loans. Management evaluates impairment on impaired loans on a quarterly basis. If, during this evaluation, impairment of the loan is identified, a chargeoff is taken at that time. As a result, as of March 31, 2019 and December 31, 2018, based upon management’s evaluation and due to the sufficiency of chargeoffs taken, none of the allowance for loan losses has been allocated to a specific impaired loan(s). The following table presents, by class, loans that were modified as TDR’s: Three months ended 3/31/2019 Three months ended 3/31/2018 New York and other states*: Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (dollars in thousands) Commercial: Commercial real estate - $ - - - $ - - Real estate mortgage - 1 to 4 family: First mortgages 4 $ 656 656 4 $ 642 642 Home equity loans - - - - - - Home equity lines of credit - - - 3 240 240 Total 4 $ 656 $ 656 7 $ 882 $ 882 Florida: Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (dollars in thousands) Commercial: Commercial real estate - $ - - - $ - - Real estate mortgage - 1 to 4 family: First mortgages - $ - - - $ - - Home equity loans - - - Home equity lines of credit - - - - - - Total - $ - - - $ - - * Includes New York, New Jersey, Vermont and Massachusetts. The addition of these TDR’s did not have a significant impact on the allowance for loan losses. In situations where the Bank considers a loan modification, management determines whether the borrower is experiencing financial difficulty by performing an evaluation of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s underwriting policy. Generally, the modification of the terms of loans was the result of the borrower filing for bankruptcy protection. Chapter 13 bankruptcies generally include the deferral of all past due amounts for a period of generally 60 months in accordance with the bankruptcy court order. In the case of Chapter 7 bankruptcies, as previously noted, even though there is no modification of terms, the borrowers’ debt to the Company was discharged and they did not reaffirm the debt. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. In situations involving a borrower filing for Chapter 13 bankruptcy protection, however, a loan is considered to be in payment default once it is 30 days contractually past due, consistent with the treatment by the bankruptcy court. The following table presents, by class, TDR’s that defaulted during the three months ended March 31, 2019 and 2018 which had been modified within the last twelve months: Three months ended 3/31/2019 Three months ended 3/31/2018 New York and other states*: Number of Contracts Recorded Investment Number of Contracts Recorded Investment (dollars in thousands) Commercial: Commercial real estate - $ - - $ - Real estate mortgage - 1 to 4 family: First mortgages - $ - - $ - Home equity lines of credit - - 1 3 Total - $ - 1 $ 3 Florida: (dollars in thousands) Number of Contracts Recorded Investment Number of Contracts Recorded Investment Commercial: Commercial real estate - $ - - $ - Real estate mortgage - 1 to 4 family: First mortgages - $ - 1 $ 72 Home equity lines of credit - - - - Total - $ - 1 $ 72 * Includes New York, New Jersey, Vermont and Massachusetts. The TDR’s that subsequently defaulted described above did not have a material impact on the allowance for loan losses. The Company categorizes commercial loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. On at least an annual basis, the Company’s loan grading process analyzes non-homogeneous loans, such as commercial and commercial real estate loans, individually by grading the loans based on credit risk. The loan grades assigned to all loan types are tested by the Company’s internal loan review department in accordance with the Company’s internal loan review policy. The Company uses the following definitions for classified loans: Special Mention Substandard Doubtful Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be “pass” rated loans. As of March 31, 2019 and December 31, 2018, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: March 31, 2019 New York and other states*: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 148,784 3,947 152,731 Other 20,985 998 21,983 $ 169,769 4,945 174,714 Florida: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 15,386 - 15,386 Other 247 - 247 $ 15,633 - 15,633 Total: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 164,170 3,947 168,117 Other 21,232 998 22,230 $ 185,402 4,945 190,347 * Includes New York, New Jersey and Massachusetts.

Included in classified loans in the above tables are impaired loans of $1.5 million and $1.4 million at March 31, 2019 and December 31, 2018, respectively. For homogeneous loan pools, such as residential mortgages, home equity lines of credit, and installment loans, the Company uses payment status to identify the credit risk in these loan portfolios. Payment status is reviewed on a daily basis by the Bank’s collection area and on a monthly basis with respect to determining the adequacy of the allowance for loan losses. The payment status of these homogeneous pools as of March 31, 2019 and December 31, 2018 is included in the aging of the recorded investment of the past due loans table. In addition, the total nonperforming portion of these homogeneous loan pools as of March 31, 2019 and December 31, 2018 is presented in the non-accrual loans table.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	(6) Fair Value of Financial Instruments Fair value measurements (ASC 820) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair values: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the value that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of assets and liabilities: Securities Available for Sale Other Real Estate Owned Impaired Loans Indications of value for both collateral-dependent impaired loans and other real estate owned are obtained from third party providers or the Company’s internal Appraisal Department. All indications of value are reviewed for reasonableness by a member of the Appraisal Department for the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value via comparison with independent data sources such as recent market data or industry-wide statistics.

Revenue from Contracts with Customers [Abstract]
Revenue from Contracts with Customers	(8) Revenue from Contracts with Customers All of the Company’s revenue from contracts with customers in the scope of ASC 606 is recognized within Non-Interest Income. The following table presents the Company’s sources of Non-Interest Income for the three months ended March 31, 2019 and 2018. Items outside the scope of ASC 606 are noted as such. Three months ended March 31, (dollars in thousands) 2019 2018 Non-interest income Service Charges on Deposits Overdraft fees $ 850 $ 827 Other 110 114 Interchange Income 1,531 1,306 Wealth management fees 1,733 1,815 Other (a) 413 617 Total non-interest income $ 4,637 $ 4,679 (a) A description of the Company’s revenue streams accounted for ASC 606 follows: Service charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction ‑ ‑ Interchange Income: Interchange revenue primarily consists of interchange fees, volume‑related incentives and ATM charges. As the card-issuing bank, interchange fees represent our portion of discount fees paid by merchants for credit / debit card transactions processed through the interchange network. The levels and structure of interchange rates are set by the card processing companies and are based on cardholder purchase volumes. The Company earns interchange income as cardholder transactions occur and interchange fees are settled on a daily basis concurrent with the transaction processing services provided to the cardholder. Wealth Management fees: TrustCo Financial Services provides a comprehensive suite of trust and wealth management products and services, including financial and estate planning, trustee and custodial services, investment management, corporate retirement plan recordkeeping and administration of which a fee is charged to manage assets for investment or transact on accounts. These fees are earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed over the period in which services are performed based on a percentage of the fair value of assets under management or administration. Other services are based on a fixed fee for certain account types, or based on transaction activity and are recognized when services are rendered. Fees are withdrawn from the customer’s account balance. Gains/Losses on Sales of Other real Estate Owned “OREO”: The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain/(loss) on sale if a significant financing component is present.

Operating Leases

Operating Leases [Abstract]
Operating Leases	(9) Operating Leases The Company adopted Topic 842 “Leases” effective January 1, 2019 and has applied the guidance to all operating leases within the scope of Topic 842 at that date. The company elected to adopt practical expedients, which among other things, does not require reassessment of lease classification. The Company has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities on the Company’s balance sheets. Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate, therefore the Company used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine present value of operating lease liabilities. Additionally, the Company does allocate the consideration between lease and non-lease components. The Company’s lease terms may include options to extend when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease components, such as fair market value adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. As of March 31, 2019 the Company does not have leases that have not yet commenced. At March 31, 2019 lease expiration dates ranged from two months to 25.5 years and have a weighted average remaining lease term of 9.8 years. Certain leases provide for increases in future minimum annual rental payments as defined in the lease agreements. As mentioned above the leases generally also include variable lease components which include real estate taxes, insurance, and common area maintenance (“CAM”) charges in the annual rental payments. Other information related to leases was as follows: (dollars in thousands) Three months ended March 31, 2019 2018 Operating lease cost $ 1,891 $ 1,912 Variable lease cost 466 586 Total Lease costs $ 2,357 $ 2,498 (dollars in thousands) Three months ended March 31, 2019 Supplemental cash flows information: Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 1,949 Right-of-use assets obtained in exchange for lease obligations: 53,029 Weighted average remaining lease term 9.8 years Weighted average discount rate 3.30 % Future minimum lease payments under non-cancellable leases as of March 31, 2019 were as follows: (dollars in thousands) Year ending December 31, 2019 (a) $ 5,799 2020 7,675 2021 7,613 2022 7,139 2023 6,812 Thereafter 32,254 Total lease payments $ 67,292 Less: Interest 10,569 Present value of lease liabilities $ 56,723 (a) The company has not recognized any options to extend as part of its ROU assets or lease liabilities. The following table presents the minimum annual lease payments under the terms of these leases, exclusive of renewal provisions at December 31, 2018: (dollars in thousands) 2019 $ 7,799 2020 7,622 2021 7,555 2022 7,048 2023 6,673 2024 and after 32,722 $ 69,419 At December 31, 2018, lease expiration dates ranged from five months to 25.8 years.

Regulatory Capital Requirements

Regulatory Capital Requirements	3 Months Ended

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements	(10) Regulatory Capital Requirements Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy regulations and, additionally for banks, the prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and became fully phased in on January 1, 2019. The capital rules include a capital conservation buffer that is designed to absorb losses during periods of economic stress and to require increased capital levels before capital distributions and certain other payments can be made. Failure to meet the full amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers. The buffer was fully implemented at 2.5% as of January 1, 2019. Management believes, as of March 31, 2019 , Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If a bank is not classified as well capitalized, regulatory approval is required to accept brokered deposits. If a bank is undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. The federal banking agencies are required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution or its holding company. Such actions could have a direct material effect on an institution’s or its holding company’s financial statements. As of March 31, 2019 and December 31, 2018, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Bank and the Company reported the following capital ratios as of March 31, 2019 and December 31, 2018: (Bank Only) As of March 31, 2019 Well Capitalized (1) Adequately Capitalized (1)(2) (dollars in thousands) Amount Ratio Tier 1 leverage capital $ 492,918 9.760 % 5.000 % 4.000 % Common equity tier 1 capital 492,918 18.299 6.500 7.000 Tier 1 risk-based capital 492,918 18.299 8.000 8.500 Total risk-based capital 526,727 19.555 10.000 10.500 As of December 31, 2018 Well Adequately (dollars in thousands) Amount Ratio Capitalized (1) Capitalized (1)(3) Tier 1 (core) capital $ 484,581 9.767 % 5.000 % 4.000 % Common equity tier 1 capital 484,581 18.233 6.500 6.380 Tier 1 risk-based capital 484,581 18.233 8.000 7.880 Total risk-based capital 517,948 19.489 10.000 9.880 (Consolidated) Minimum for Capital Adequacy plus Capital Conservation Buffer (1)(2) As of March 31, 2019 (dollars in thousands) Amount Ratio Tier 1 leverage capital $ 508,176 10.057 % 4.000 % Common equity tier 1 capital 508,176 18.856 7.000 Tier 1 risk-based capital 508,176 18.856 8.500 Total risk-based capital 542,003 20.111 10.500 (dollars in thousands) Minimum for Capital Adequacy plus Capital Conservation Buffer (1)(2) As of December 31, 2018 Amount Ratio Tier 1 leverage ratio $ 499,626 10.129 % 4.000 % Common equity Tier 1 capital 499,626 18.790 6.380 Tier 1 risk-based capital 499,626 18.790 7.880 Total risk-based capital 533,009 20.046 9.880 (1) Federal regulatory minimum requirements to be considered to be Well Capitalized and Adequately Capitalized (2) The March 31, 2019 common equity tier 1, tier 1 risk-based, and total risk-based capital ratios include a capital conservation buffer of 2.50 percent (3) The December 31, 2018 common equity tier 1, tier 1 risk-based, and total risk-based capital ratios include a transition capital conservation buffer of 1.88 percent

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	(11) New Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016 02, Leases (Topic 842) (“ASU 2016 02”). ASU 2016 02 is intended to improve financial reporting of leasing transactions by requiring organizations that lease assets to recognize assets and liabilities for the rights and obligations created by leases that extend more than twelve months on the balance sheet. This accounting update also requires additional disclosures surrounding the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016 02 is effective for financial statements issued for annual and interim periods beginning after December 15, 2018 for public business entities. Early adoption is permitted. The Company elected to adopt ASU 2016 02 as of January 1, 2019. The Company has elected the package of practical expedients permitted in ASC Topic 842. Accordingly, the Company accounted for its existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contracts contain a lease under ASC Topic 842, (b) whether classification of the operating leases would be different in accordance with ASC Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in ASC Topic 842 at lease commencement. The company has also elected the practical expedient to use hindsight in determining the lease term. As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $58.2 million, which represents the present value of the remaining lease payments of approximately $69.4 million, discounted using the Company’s incremental borrowing rate, and (b) a ROU asset of approximately $53.0 million which represents the lease liability of $58.2 million adjusted for accrued rent of approximately $5.2 million. This standard did not have a material impact on the Company’s balance sheets or cash flows from operations and had no impact on the Company’s operating results. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases. In June 2016, the FASB released ASU 2016-13, “Financial Instruments – Credit Losses” which amended existing guidance to replace current generally accepted accounting principles used to measure a reporting entity’s credit losses. The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2019. The ASU represents a significant departure from current GAAP and the Company is evaluating the impact of the ASU on its consolidated financial statements, which includes developing a roadmap for implementation of the new standard. In February 2018, the FASB issued ASU 2018-02, “Income statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” which will allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. These amendments are effective for all entities for fiscal years beginning after December 15, 2018. For Interim periods within those fiscal years, early adoption of the amendment is permitted including public business entities for reporting periods for which financial statements have not yet been issued. The Company did adopt the ASU in the first quarter of 2018 and reclassified the stranded tax effect in accumulated other comprehensive income to retained earnings in the period ended March 31, 2018.
