Basis of Financial Statement Presentation
Basis of Financial Statement Presentation	Note 1 — Basis of Financial Statement Presentatio n ​ Description of Business ​ Chase Corporation (the “Company,” “Chase,” “we,” or “us”), a global specialty chemicals company founded in 1946, is a leading manufacturer of protective materials for high-reliability applications across diverse market sectors. The Company’s strategy is to maximize the performance of its core businesses and brands while seeking future opportunities through strategic acquisitions. Through investments in facilities, systems and organizational consolidation, the Company seeks to improve performance and gain economies of scale. ​ Basis of Presentation ​ The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States of America generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, and instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Therefore, they do not include all information and footnote disclosures necessary for a complete presentation of Chase Corporation’s financial position, results of operations and cash flows in conformity with generally accepted accounting principles. The year-end condensed balance sheet was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. Chase Corporation filed audited consolidated financial statements which included all information and notes necessary for such a complete presentation for the three years ended August 31, 2021 in conjunction with its 2021 Annual Report on Form 10-K. Certain immaterial reclassifications have been made to the prior year amounts to conform to the current year’s presentation. ​ The results of operations for the interim period ended May 31, 2022 are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended August 31, 2021 which are contained in the Company’s 2021 Annual Report on Form 10-K. ​ The accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring items) that are, in the opinion of management, necessary for a fair statement of the Company’s financial position as of May 31, 2022, and the results of its operations, comprehensive income, changes in equity and cash flows for the interim periods ended May 31, 2022 and 2021. ​ The financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company uses the U.S. dollar as the reporting currency for financial reporting. The financial position and results of operations of the Company’s U.K.-based operations are measured using the British pound as the functional currency. The financial position and results of operations of the Company’s operations based in France are measured using the euro as the functional currency. The financial position and results of the Company’s HumiSeal India Private Limited business are measured using the Indian rupee as the functional currency. The functional currency for all Chase Corporation’s other operations is the U.S. dollar. Foreign currency translation gains and losses are determined using current exchange rates for monetary items and historical exchange rates for other balance sheet items and are recorded as a change in other comprehensive income. Transaction gains and losses generated from the remeasurement of assets and liabilities denominated in currencies other than the functional currency of each applicable operation are included in other income (expense) on the condensed consolidated statements of operations, and   ​ ​ Other Business Developments ​ The Company substantially completed the relocation of its Corporate Headquarters to another location within Westwood, MA during the second quarter of the fiscal year. The move, part of the Company’s ongoing consolidation and optimization initiative, capitalizes on the hybrid work model utilized by many of Chase’s corporate and administrative employees and is expected to provide future operational cost savings. The new facility also consolidates and houses research and development operations previously conducted at the previous Westwood, MA and Woburn, MA locations. Operations optimization costs related to the Westwood move of $32 and $232 were expensed in the third quarter and year-to-date fiscal period, respectively. The Company does not anticipate any significant additional operations optimization costs related to the new Corporate Headquarters during the fourth quarter of the fiscal year. ​ During the third quarter of fiscal 2021, Chase announced to the employees at its Woburn, MA location that its adhesives systems operations, part of the Adhesives, Sealants and Additives segment’s electronic and industrial coatings product line, would be consolidating into the Company’s existing O'Hara Township, PA location. This rationalization and consolidation initiative aligns with the announcement in the second quarter of fiscal 2021 of the Company’s plan to move its sealant systems production from Newark, CA to Hickory, NC, described in more detail below. Chase Corporation obtained both the adhesive and sealants systems as part of its fiscal 2017 acquisition of the operations of Resin Designs. The Company expensed $27 and $328 related to the consolidation of the Woburn, MA location during the third quarter and year-to-date fiscal period, respectively, and expects to recognize additional expense during the fourth quarter of the fiscal year. ​ On February 5, 2021, the Company acquired certain assets of Emerging Technologies, Inc. (“ETi”), a superabsorbent polymers solutions provider, located in Greensboro, NC. The business was acquired for a purchase price of $9,997 comprising $8,997 paid on February 5, 2021 and an accrual of $1,000 to be paid out up to eighteen months after purchase, subsequent to final working capital adjustments, and excluding acquisition-related costs. As part of this transaction, Chase acquired substantially all working capital and fixed assets of the business and entered a multi-year lease at ETi’s existing location. The Company expensed $128 of acquisition-related costs during the second quarter of fiscal 2021 associated with this acquisition. The purchase was funded with available cash on hand. ETi is a solutions provider and formulator of absorbent polymers for use in the packaging, recreational, consumer, and sanitation markets. The acquisition broadens the Company’s superabsorbent polymers product offerings and formulation capabilities while expanding its market reach. The Company finalized purchase accounting during the first quarter of fiscal 2022, with no significant change to amounts initially recorded. Since the effective date of the acquisition, the financial results of ETi’s acquired operations have been included in the Company’s financial statements within the functional additives product line, contained within the Adhesives, Sealants and Additives operating segment. ​ During the second quarter of fiscal 2021, Chase began moving the sealant systems operations, part of the Adhesives, Sealants and Additives segment’s electronic and industrial coatings product line, from its Newark, CA location to its Hickory, NC facility. This is in line with the Company’s ongoing initiative to consolidate its manufacturing plants and streamline its existing processes. The sealant systems operations and Newark, CA location came to Chase Corporation as part of the fiscal 2017 acquisition of the operations of Resin Designs, and the Company’s lease there terminated in fiscal 2021. The Company recognized $977 in expense related to the move during the entire prior fiscal year ended August 31, 2021 and $147 of expense in the first half of fiscal 2022. This project is now substantially completed and any future costs related to this move are not anticipated to be significant to the condensed consolidated financial statements. ​ ​ On September 1, 2020 (the first day of fiscal 2021), the Company acquired all the capital stock of ABchimie for €18,654 (approximately $22,241 at the time of the transaction) net of cash acquired, subsequent to final working capital adjustment, excluding acquisition-related costs totaling $274 recognized in fiscal 2020 and with a potential earn out based on performance potentially worth an additional €7,000 (approximately $8,330 at the time of the transaction). ABchimie is a Corbelin, France headquartered solutions provider for the cleaning and protection of electronic assemblies, with ‎further formulation, production, and research and development capabilities‎. The transaction was funded with cash on hand. Since the effective date of the acquisition, the financial results of the business have been included in the Company's financial statements within the Adhesives, Sealants and Additives operating segment in the electronic and industrial coatings product line. ​ Significant Accounting Policies ​ The Company’s significant accounting policies are detailed in Note 1

The ASU is effective for the Company beginning September 1, 2022 (the start of fiscal 2023). ASU 2021-10 has not had, and the Company does not expect it to have in future periods, a material impact on the Company’s condensed consolidated financial statements and disclosures. ​ Recently Adopted Accounting Pronouncements ​ In October 2021, the FASB issued ASU No. 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”, which amends the accounting for contract assets and contract liabilities from revenue contracts with customers in a business combination. The amendment requires that an entity acquiring the contract assets and contract liabilities in a business combination be recognized in accordance with ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The ASU is effective for all public entities for fiscal years beginning after December 15, 2022, and interim periods therein. The Company early adopted ASU 2021-08 on February 28, 2022 and any impact on the condensed consolidated financial statements will be dependent on the magnitude and nature of future acquired entities. ​

The Company has identified a total of three reporting units, corresponding to its three operating segments, that are used to evaluate the possible impairment of goodwill. Assessments of possible impairment of goodwill are made when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable through future operations. Additionally, testing for possible impairment of recorded goodwill and certain intangible asset balances is required annually. The amount and timing of any impairment charges based on these assessments require the estimation of future cash flows and the fair market value of the related assets based on management’s best estimates of certain key factors, including future selling prices and volumes; operating, raw material and energy costs; and various other projected operating and economic factors, including the anticipated future impact of the ​ The Company has adopted ASU No. 2017-04 “Intangibles - Goodwill and Other Topics (Topic 350): Simplifying the Test for Goodwill Impairment.” The Company assesses goodwill for impairment by comparing the fair value of the reporting unit to its carrying amount. If the fair value of a reporting unit is less than its carrying value, an impairment loss, limited to the amount of goodwill allocated to that reporting unit, is recorded. ​ Intangible assets subject to amortization consisted of the following as of May 31, 2022 and August 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted Average ​ Gross Carrying ​ Accumulated ​ Net Carrying ​ ​ Amortization Period Value Amortization Value May 31, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Patents and agreements ​ 14.6 years $ 1,760 ​ $ 1,722 ​ $ 38 ​ Formulas and technology ​ 7.8 years ​ 10,844 ​ ​ 9,989 ​ ​ 855 ​ Trade names ​ 5.9 years ​ 8,747 ​ ​ 8,435 ​ ​ 312 ​ Customer lists and relationships ​ 9.1 years ​ 115,102 ​ ​ 79,360 ​ ​ 35,742 ​ ​ ​ ​ ​ $ 136,453 ​ $ 99,506 ​ $ 36,947 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ August 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Patents and agreements ​ 14.6 years $ 1,760 ​ $ 1,715 ​ $ 45 ​ Formulas and technology ​ 7.9 years ​ 10,987 ​ ​ 9,769 ​ ​ 1,218 ​ Trade names ​ 5.9 years ​ 8,836 ​ ​ 8,285 ​ ​ 551 ​ Customer lists and relationships ​ 9.2 years ​ 116,855 ​ ​ 71,715 ​ ​ 45,140 ​ ​ ​ ​ ​ $ 138,438 ​ $ 91,484 ​ $ 46,954 ​ ​ Aggregate amortization expense related to intangible assets for the nine months ended May 31, 2022 and 2021 was $9,092 and $9,566 respectively.

Leases
Leases	Note 8 — Leases ​ The Company accounts for leases in accordance to ASU 2016-02, “Leases (Topic 842).” At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present in the arrangement. Leases with a term greater than one year are recognized on the balance sheet as right-of-use (ROU) assets and short-term and long-term lease liabilities, as applicable. The Company does not have any financing leases that are material in nature. ​ Operating lease liabilities and their corresponding right-of-use assets are initially recorded based on the present value of lease payments over the expected remaining lease term. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate to discount lease payments, which reflects the fixed rate at which the Company believes it could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment. ​ The Company has elected not to recognize leases with an original term of one year or less on the balance sheet. The Company typically only includes an initial lease term in its assessment of a lease arrangement. Options to renew a lease are not included in the Company’s assessment unless there is reasonable certainty that the Company will renew. ​ The following table presents the right-of-use asset and short-term and long-term lease liabilities amounts recorded on the condensed consolidated balance sheet as of May 31, 2022 and August 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ May 31, ​ August 31, ​ ​ 2022 ​ 2021 Assets ​ ​ ​ ​ Operating lease right-of-use asset ​ $ 9,078 ​ $ 9,312 ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ Current (accrued expenses) ​ $ 1,466 ​ $ 1,515 Operating lease long-term liabilities ​ ​ 7,060 ​ ​ 7,202 Total lease liability ​ $ 8,526 ​ $ 8,717 ​ ​ ​ ​ ​ ​ ​ ​ ​ Lease cost The components of lease costs for the three and nine months ended May 31, 2022 and 2021 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended May 31, ​ ​ Nine Months Ended May 31, ​ ​ 2022 ​ 2021 ​ ​ 2022 ​ 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating lease cost (a) ​ $ 790 ​ $ 911 ​ ​ $ 2,451 ​ $ 2,833 ​ (a) Includes short-term leases and variable lease costs (e.g. common area maintenance), which are immaterial. ​ Maturity of lease liability The maturity of the Company's lease liabilities at May 31, 2022 was as follows: ​ ​ ​ ​ ​ ​ ​ Future Operating Year ending August 31, Lease Payments 2022 (remaining 3 months) ​ ​ 427 2023 ​ ​ 1,677 2024 ​ ​ 1,602 2025 ​ ​ 1,444 2026 ​ ​ 1,182 2027 and thereafter ​ ​ 3,002 Less: Interest ​ ​ (808) Present value of lease liabilities ​ $ 8,526 ​ ​ The weighted average remaining lease term and discount rates are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ May 31, ​ August 31, ​ ​ ​ 2022 ​ 2021 ​ Lease Term and Discount Rate ​ ​ ​ ​ ​ Weighted average remaining lease term (years) ​ ​ ​ ​ ​ ​ ​ Operating leases ​ ​ 6.7 ​ ​ 6.8 ​ Weighted average discount rate (percentage) ​ ​ ​ ​ ​ ​ ​ Operating leases ​ ​ 2.8 % ​ 3.1 % ​ Other Information Supplemental cash flow information related to leases is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended May 31, ​ ​ 2022 ​ 2021 ​ ​ ​ ​ ​ ​ ​ Operating cash outflows from operating leases ​ $ 1,311 ​ $ 1,797 Total cash paid for amounts included in the measurement of lease liabilities ​ $ 1,311 ​ $ 1,797 ​

Revenue from Contracts with Customers
Revenue from Contracts with Customers	Note 9 — Revenue from Contracts with Customers ​ The Company accounts for revenue in accordance with ASC 606, “Revenue from Contracts with Customers.” The Company’s revenue is generated from the manufacture of specialty chemical products including coatings, linings, adhesives, sealants, specialty tapes, polymers and laminates. Certain of these manufactured products can incorporate customer-owned materials. The Company also recognizes, to a lesser extent, revenue through royalties and commissions from licensed manufacturers and from providing custom manufacturing-related services. The Company’s revenue recognition policies require the Company to make significant judgments and estimates. In applying the Company’s revenue recognition policy, determinations must be made as to when control of products passes to the Company’s customers, which can be either at a point in time or over time based on contractual terms with customers. Revenue is generally recognized at a point in time when control passes upon either shipment to or receipt by the customer of the Company’s products, while revenue is generally recognized over time when control of the Company’s products transfers to customers during the manufacturing process. ​ Contract Balances ​ The Company’s contract assets primarily relate to unbilled revenue for products currently in production at the Company’s facilities and which incorporate customer-owned material. Revenue is recognized in advance of billing to the customer in these specific circumstances, whereas billing is typically performed at the time of shipment to or receipt by the customer. ​ Contract assets are included in prepaid expenses and other current assets on the Company’s condensed consolidated balance sheet.

Commitments and Contingencies	​ Note 10 — Commitments and Contingencies ​ The Company is involved from time to time in litigation incidental to the conduct of its business. Although the Company does not expect that the outcome in any of these matters, individually or collectively, will have a material adverse effect on its financial condition, results of operations or cash flows, litigation is inherently unpredictable. Therefore, judgments could be rendered, or settlements agreed to that could adversely affect the Company’s operating results or cash flows in a particular period. The Company routinely assesses all its litigation and threatened litigation as to the probability of ultimately incurring a liability and records its best estimate of the ultimate loss in situations where it assesses the likelihood of loss as probable.

Fair Value Measurements
Fair Value Measurements	Note 12 — Fair Value Measurements ​ The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values. These tiers are: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. ​ The Company utilizes the best available information in measuring fair value. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The financial assets classified as Level 1 and Level 2 as of May 31, 2022 and August 31, 2021 represent investments that are restricted for use in nonqualified retirement savings plans for certain key employees and directors. ​ The following table sets forth the Company’s financial assets that were accounted for at fair value on a recurring basis as of May 31, 2022 and August 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value measurement category ​ ​ ​ ​ ​ ​ ​ ​ Quoted prices ​ Significant other ​ Significant ​ ​ ​ Fair value ​ ​ ​ ​ in active markets ​ observable inputs ​ unobservable inputs ​ ​ measurement date Total (Level 1) (Level 2) (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Restricted investments ​ May 31, 2022 ​ $ 2,312 ​ $ 2,070 ​ $ 242 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Restricted investments ​ August 31, 2021 ​ $ 2,260 ​ $ 2,016 ​ $ 244 ​ $ — ​ ​ The following table presents the fair value of the Company’s liabilities that are accounted for at fair value on a recurring basis as of May 31, 2022 and August 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value measurement category ​ ​ ​ ​ ​ ​ ​ ​ Quoted prices ​ Significant other ​ Significant ​ ​ ​ Fair value ​ ​ ​ ​ in active markets ​ observable inputs ​ unobservable inputs ​ ​ measurement date Total (Level 1) (Level 2) (Level 3) Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Long-term debt ​ May 31, 2022 ​ $ — ​ $ — ​ $ — ​ $ — ​ Contingent consideration ​ May 31, 2022 ​ $ 2,099 ​ $ — ​ $ — ​ $ 2,099 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Long-term debt ​ August 31, 2021 ​ $ — ​ $ — ​ $ — ​ $ — ​ Contingent consideration ​ August 31, 2021 ​ $ 2,537 ​ $ — ​ $ — ​ $ 2,537 ​ ​ The long-term debt (including any current portion of long-term debt) had no outstanding balance as of May 31, 2022 and August 31, 2021. The carrying value of the long-term debt approximates its fair value, as the interest rate is set based on the movement of the underlying market rates. See Note 16 to the condensed consolidated financial statements for additional information on long-term debt. ​ In connection with accounting for the ABchimie acquisition on September 1, 2020, the Company recorded a contingent consideration liability included within Other liabilities on the condensed consolidated balance sheet of €780 (approximately $928) on the acquisition date, representing the fair value of contingent consideration payable upon the achievement of a performance-based target. The contingent consideration liability was valued using a Monte Carlo simulation model in an option pricing framework based on key inputs that are not all observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The Company assesses the fair value of the contingent consideration liability at each reporting period. Any subsequent changes in the estimated fair value of the liability are reflected in Loss (gain) on contingent consideration on the condensed consolidated statement of operations until the liability is settled. As of May 31, 2022, the liability decreased to $2,099 predominantly due to changes in non-market data assumptions as well as a shorter period to the payment date.

Income Taxes
Income Taxes	Note 14 — Income Taxes ​ For the three and nine months ended May 31, 2022, the Company’s recognized effective tax rate was 19.7% and 23.3%, respectively. For the three and nine months ended May 31, 2021, the Company’s recognized effective tax rate was 19.5% and 23.1%, respectively. ​ The Company has applied the U.S. statutory Federal rate of 21%, enacted as part of the Tax Cuts and Jobs Act (the “Tax Act”) in December 2017, for both the third quarter and year-to-date fiscal periods ended May 31, 2022 and 2021. ​ In addition, the Company also recognizes an additional component of total Federal tax expense, the tax on Global Intangible Low-Taxed Income (“GILTI”) provision of the Tax Act, which became applicable to the Company in fiscal 2019. The Company elected to account for GILTI as a period cost, and therefore included GILTI expense in the effective tax rate calculation. This provision did not have a material effect on the effective tax rate for the third quarter and year-to-date fiscal periods ended May 31, 2022 and 2021. Additionally, the Company concluded that the Base Erosion and Anti Abuse Tax (“BEAT”) provision of the Tax Act, which also became applicable to the Company in fiscal 2019, had no effect on its effective tax rate for the third quarter and year-to-date fiscal periods ended May 31, 2022 and 2021. ​ On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, included a technical correction to the Tax Act which will allow accelerated deductions for qualified improvement property. The Company has evaluated the impact of the CARES Act, and at present does not expect that the qualified improvement property correction or other provisions of the CARES Act will result in a material tax benefit in future periods. The CARES Act had no material effect on the effective tax rate for the third quarter and year-to-date fiscal periods ended May 31, 2022 and 2021. ​ In July 2020, the United States Internal Revenue Service (“IRS”) released final regulations (TD 9901) that ease documentation standards and provide greater flexibility for taxpayers claiming the deduction for Foreign-Derived Intangible Income (“FDII”). During the third quarter and year-to-date fiscal periods ended May 31, 2022, FDII had a favorable impact on the Company’s effective tax rate.

Operations Optimization Costs	0 Note 15 — Operations Optimization Costs ​ Relocation of Chase Corporate Headquarters ​ The Company substantially completed the relocation of its Corporate Headquarters to another location within Westwood, MA during the second quarter of the fiscal year 2022. The move, part of the Company’s ongoing consolidation and optimization initiative, capitalizes on the hybrid work model utilized by many of Chase’s corporate and administrative employees and is expected to provide future operational cost savings. The new facility also consolidates and houses research and development operations previously conducted at the previous Westwood, MA and Woburn, MA locations. Operations optimization expenses related to the Westwood move of $32 and $232 were expensed in the third quarter and fiscal year-to-date period of 2022, respectively. The Company does not anticipate any significant additional operations optimization costs related to the new Corporate Headquarters during the fourth quarter of the fiscal year. ​ Relocation of Adhesives Systems Manufacturing to O'Hara Township, PA ​ During the third quarter of fiscal 2021, Chase announced to the employees at its Woburn, MA location that its adhesives systems operations, part of the Adhesives, Sealants and Additives segment’s electronic and industrial coatings product line, would be consolidating into the Company’s existing O'Hara Township, PA location. This rationalization and consolidation initiative aligns with the announcement in the second quarter of fiscal 2021 of the Company’s plan to move its sealant systems production from Newark, CA to Hickory, NC, described in more detail below. Chase Corporation obtained both the adhesive and sealants systems as part of its fiscal 2017 acquisition of the operations of Resin Designs. The Company expensed $27 and $328 related to the consolidation of the Woburn, MA location during the third quarter and fiscal 2022 period, respectively, and expects to recognize additional expense during the fourth quarter of the fiscal year. ​ Relocation of Sealants Systems Manufacturing to Hickory, NC ​ During the second quarter of fiscal 2021, Chase began moving the sealant systems operations, part of the Adhesives, Sealants and Additives segment’s electronic and industrial coatings product line, from its Newark, CA location to its Hickory, NC facility. This is in line with the Company’s ongoing initiative to consolidate its manufacturing plants and streamline its existing processes. The sealant systems operations and Newark, CA location came to Chase Corporation as part of the fiscal 2017 acquisition of the operations of Resin Designs, and the Company’s lease there terminated in fiscal 2021. The Company recognized $977 of expense related to the move during the entire prior fiscal year ended August 31, 2021 and $0 and $147 of expense in the third quarter and year-to-date fiscal 2022. This project is now substantially completed and any future costs related to this move are not anticipated to be significant to the condensed consolidated financial statements. ​ ​

Long-Term Debt
Long-Term Debt	​ Note 16 — Long-Term Debt ​ On July 27, 2021 (the fourth quarter of fiscal 2021), the Company entered into the Second Amended and Restated Credit Agreement (the “New Credit Agreement”) by and among the Company and NEPTCO Incorporated (“NEPTCO”), each as borrowers, the guarantor subsidiaries party thereto, the financial institutions party thereto as Lenders, and Bank of America, N.A., as administrative agent, with participation from Wells Fargo Bank, N.A., PNC Bank, N.A. and JPMorgan Chase Bank, N.A. The New Credit Agreement was entered into to amend, restate and extend the Company’s preexisting Amended and Restated Credit Agreement (the “Prior Credit Agreement”), which had a maturity date of December 15, 2021, and to provide for additional liquidity to finance acquisitions, working capital and capital expenditures, and for other general corporate purposes. Under the New Credit Agreement, Chase obtained an increased revolving credit loan (the “New Revolving Facility”), with borrowing capabilities not to exceed $200,000 at any time, with the ability to request an increase in this amount by an additional $100,000 at the individual or collective option of any of the Lenders. The applicable interest rate for the New Revolving Facility and New Term Loan (defined below) is based on the effective London Interbank Offered Rate (LIBOR) plus a range of 1.00% to 1.75%, depending on the consolidated net leverage ratio of Chase and its subsidiaries. At May 31, 2022, there was no outstanding principal balance, and as such, no applicable interest rate. ​ The New Credit Agreement has a five-year term with interest payments due at the end of the applicable LIBOR period (but in no event less frequently than the three-month anniversary of the commencement of such LIBOR period) and principal payment due at the expiration of the agreement, July 27, 2026. The New Credit Agreement contains provisions that may replace LIBOR as the benchmark index under certain circumstances. In addition, the Company may elect a base rate option for all or a portion of the New Revolving Facility, in which case interest payments shall be due with respect to such portion of the New Revolving Facility on the last business day of each quarter. Subject to certain conditions set forth in the New Credit Agreement, the Company may elect to convert all or a portion of the outstanding New Revolving Facility into a new term loan twice during the term of the New Revolving Facility (each, a “New Term Loan”, and collectively with the New Revolving Facility, the “New Credit Facility”), which New Term Loan shall be payable quarterly in equal installments sufficient to amortize the original principal amount of such Term Loan on a ten year amortization schedule. ​ The outstanding balance on the New Credit Facility is guaranteed by all of Chase’s direct and indirect domestic subsidiaries, which collectively had a carrying value of approximately $302,914 at May 31, 2022. The New Credit Facility is subject to restrictive covenants under the New Credit Agreement, and financial covenants that require Chase and its subsidiaries to maintain certain financial ratios on a consolidated basis, including a consolidated net leverage ratio of 3.25 to 1.00 and a consolidated interest coverage ratio of 3.50 to 1.00 (both defined in the New Credit Agreement). Chase Corporation was in compliance with the debt covenants as of May 31, 2022. The New Credit Agreement also places certain Lender-approval requirements as to the size of permitted acquisitions which may be entered into by the Company and its subsidiaries, and allows for a temporary step-up in the allowed consolidated leverage ratio for the four fiscal quarters ending after certain designated acquisitions. Prepayment is allowed by the New Credit Agreement at any time during the term of the agreement, subject to customary notice requirements and the payment of customary LIBOR breakage fees. ​ The Prior Credit Agreement was an all-revolving credit facility with a borrowing capacity of $150,000, which could be increased by an additional $50,000 at the request of the Company and the individual or collective option of any of the lenders, and with an interest rate based on the effective LIBOR plus an additional amount in the range of 1.00% to 1.75%, depending on our consolidated net leverage ratio or, at the Company’s option, at the bank’s base lending rate. It was substantially available at July 27, 2021, the time of its amendment and restatement. ​ ​ ​ ​ ​ ​

Acquisitions	​ Note 17 – Acquisitions ​ Acquisition of Emerging Technologies, Inc. ​ On February 5, 2021, the Company acquired certain assets of Emerging Technologies, Inc. (“ETi”), a superabsorbent polymers solutions provider, located in Greensboro, NC. The business was acquired for a purchase price of $9,997 , comprising $8,997 paid on February 5, 2021 and an accrual of $1,000 to be paid out up to eighteen months after the purchase, subsequent to final working capital adjustments, and excluding acquisition-related costs. As part of this transaction, Chase acquired substantially all working capital and fixed assets of the business and entered a multi-year lease at ETi’s existing location. The Company expensed $128 of acquisition-related costs during the three-month period ended February 28, 2021 associated with this acquisition. The purchase was funded with available cash on hand. ETi is a solutions provider and formulator of absorbent polymers for use in the packaging, recreational, consumer, and sanitation markets. The acquisition broadens the Company’s superabsorbent polymers product offerings and formulation capabilities while expanding its market reach. The Company finalized purchase accounting during the first quarter of fiscal 2022, with no significant change to amounts initially recorded. Since the effective date of the acquisition, the financial results of ETi’s acquired operations have been included in the Company’s financial statements within the functional additives product line, contained within the Adhesives, Sealants and Additives operating segment. The ETi acquisition does not represent a significant business combination so pro forma financial information is not provided. ​ The excess of the purchase price over the net tangible and intangible assets acquired resulted in goodwill of $2,451 that is largely attributable to the synergies and economies of scale from combining the operations, technologies and research and development capabilities of ETi and Chase, particularly as they pertain to the expansion of the Company's product and service offerings, the established workforce and marketing efforts. This goodwill is deductible for income tax purposes. ​ Acquisition of ABchimie ​ On September 1, 2020 (first day of fiscal 2021), the Company acquired all the capital stock of ABchimie for €18,654 (approximately $22,241 at the time of the transaction) net of cash acquired, subject to final working capital adjustments, excluding acquisition-related costs totaling $274 recognized in fiscal 2020 and with a performance-based earn out (measured over four years post-acquisition) potentially worth an additional €7,000 (approximately $8,330 at the time of the transaction). The Company had $2,692 accrued at February 28, 2022 within Other liabilities on the condensed consolidated balance sheet related to its estimate of the current fair value of the earn out. Following its initial recording at the acquisition date, changes in the performance-based earn out accrual have been recorded within (Gain) loss on contingent consideration in the condensed consolidated statement of operations (including a $474 gain in the third quarter and $199 year-to-date net gain adjustment in fiscal 2022). ​ ABchimie is a Corbelin, France headquartered solutions provider for the cleaning and protection of electronic assemblies, with ‎further formulation, production, and research and development capabilities‎. The transaction was funded with available cash on hand. The financial results of the business are included in the Company's financial statements within the Adhesives, Sealants and Additives operating segment in the electronic and industrial coatings product line. The Company finalized purchase accounting during the fourth quarter of fiscal 2021, with no significant change to amounts initially recorded. The excess of the purchase price over the net tangible and intangible assets acquired resulted in goodwill of $13,055 that is largely attributable to the synergies and economies of scale from combining the operations, technologies and research and development capabilities of ABchimie and Chase, particularly as they pertain to the expansion of the Company's product and service offerings, the established workforce and marketing efforts. A portion of this goodwill is deductible in the U.S. for calculation of GILTI period costs but is nondeductible for French income tax purposes.
