Basis of Presentation and New Significant Accounting Policy
Basis of Presentation and New Significant Accounting Policy	Organization and Business CSP Inc. ("CSPi" or "CSPI" or "the Company" or "we" or "our") was incorporated in 1968 and is based in Lowell, Massachusetts. CSPi and its subsidiaries develop and market IT integration solutions, advanced security products, managed IT services, purpose built network adapters, and high-performance cluster computer systems to meet the diverse requirements of its commercial and defense customers worldwide. The Company operates in two segments, its Technology Solutions (“TS”) segment and High Performance Products (“HPP”) segment. 1. Basis of Presentation and New Significant Accounting Policy Basis of Presentation The accompanying interim condensed consolidated financial statements have been prepared by the Company and reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. All adjustments were of a normal recurring nature. Certain information and footnote disclosures normally included in the annual consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States, have been omitted. Accordingly, the Company believes that although the disclosures are adequate to make the information presented not misleading, the unaudited condensed consolidated financial statements should be read in conjunction with the notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023. Presentation – sales whose payment terms exceed one year Effective in fiscal year 2024 sales whose payment terms exceed one year is now presented as “Financing receivables, net of allowances” on the Consolidated Balance Sheets rather than being combined with Accounts receivable, net of allowances. The financial statement line item Long-term receivable is now labeled as “Financing receivables due after one year, net of allowances.” These changes are reflected retrospectively as of September 30, 2023. This change was made to provide more detail on the balance sheet related to these receivables and align with our notes to the unaudited condensed consolidated financial statements. Presentation – two-for-one stock split On February 21, 2024, the Board of Directors of CSP Inc. approved an amendment to the Company’s Articles of Organization to increase the total number of its authorized shares of Common Stock, par value $0.01 , from 7,500,000 shares to 9,753,900 shares (the “Amendment”). No shareholder approval was required under the Massachusetts Business Corporation Act with respect to the Amendment. The Amendment became effective upon filing with the Secretary of the Commonwealth of Massachusetts on February 21, 2024. ​ On June 26, 2024, the stockholders of CSP, Inc. approved an amendment to the Company's Articles of Organization, as amended (the "Articles of Organization"), to increase the number of authorized shares of Common Stock from 9,753,900 to 20,000,000 (the "Amendment"). On June 26, 2024, the Company filed an Articles of Amendment to the Articles of Organization with the Secretary of the Commonwealth of Massachusetts to effect the Amendment, which became effective immediately upon such filing. This amendment is included as Exhibit 3.1 and is incorporated herein by reference. ​ On February 21, 2024, the Company announced its Board of Directors approved and declared a two -for-one stock split to be effected in the form of a 100% stock dividend. The stock dividend was paid on March 20, 2024 to shareholders of record as of the close of business on March 6, 2024. In accordance with ASC 505 Equity , specifically ASC 505-20-25-3 through ASC 505-20-25-6 , we have determined this had a material effect on reducing share market value and therefore was treated this event as a stock split for accounting purposes. All common shares and per share amounts contained in these condensed interim financial statements and notes have been retrospectively restated to reflect this two -for-one stock split in the form a 100% dividend in accordance with ASC 260 Earnings Per Share , specifically ASC 260-10-55-12 . Use of estimates The preparation of condensed consolidated interim financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates and assumptions are related to the allowance for credit losses for accounts receivable and financing receivables, reserves for inventory obsolescence, the impairment assessment of intangible assets, right-of-use assets and lease liabilities, and the calculation of standalone selling price for revenue recognition, the calculation of liabilities related to deferred compensation and retirement plans and the calculation of income tax liabilities. Actual results may differ from those estimates under different assumptions or conditions. Significant Accounting Policies Except for the change in certain accounting policies upon adoption of the accounting standard described below, there have been no significant changes to the Company's significant accounting policies described in PART II, Item 8, Note 1 Summary of Significant Accounting Policies Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting standards update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) The Company adopted ASU 2016-13 (the “new CECL standard”) as of October 1, 2023 using the modified retrospective method, with a cumulative-effect adjustment to the opening balance of Shareholders’ equity as of October 1, 2023. The adoption primarily impacted the estimation of our Allowance for credit losses for Accounts receivable and Financing receivables. Additionally, it affected allowance for credit losses of contract assets with effects being immaterial. The total impact recorded on our initial adoption of ASU 2016-13 as of October 1, 2023 included an increase of Accounts receivable, net of $67k and a decrease of Financing receivables, net in the amount of $82k with the total adjustment decreasing retained earnings of $15k. For the accounting policies adopted and details of impacts from adoption refer to Note 4 - Accounts receivable, net Note 5 - Financing receivables, net ​ Recently Accounting Pronouncements Not Yet Adopted Improvements to Reportable Segment Disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), which requires disclosure of incremental segment information on an annual and interim basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures.

Revenue	2. Revenue We derive revenue from the sale of integrated hardware and software, third-party service contracts, professional services, managed services, financing of hardware and software, and other services. We recognize revenue from hardware upon transfer of control, which is at a point in time typically upon shipment when title transfers. Revenue from software is recognized at a point in time when the license is granted. Professional services generally include implementation, installation, and training services. Professional services are considered a series of distinct services that form one performance obligation and revenue is recognized over time as services are performed. Revenue generated from managed services is recognized over the term of the contract. Certain managed services contracts include financing of hardware and software. Revenues from arrangements which include financing are allocated considering relative standalone selling prices of lease and non-lease components within the agreement. The lease component includes hardware, which is subject to ASC 842, Leases Revenue from Contracts with Customers Other services generally include revenue generated through our royalty, extended warranty, multicomputer repair, and maintenance contracts. Royalty revenue is sales-based and recognized on the date of subsequent sale of the product, which occurs on the date of customer shipment. Revenue from extended warranty contracts is recognized ratably over the warranty period. Multicomputer repair services revenue is recognized upon control transfer when the customer takes possession of the computer at time of shipping. Revenue generated from maintenance services is recognized evenly over the term of the contract. The right of return risk lies with the original manufacturer of the product. Managed service contracts contain the right to refund if canceled within 30 days of inception. Any products with a standard warranty are treated as a warranty obligation under ASC 460, Guarantees. The following policies are applicable to our major categories of segment revenue transactions: TS Segment Revenue TS Segment revenue is derived from the sale of hardware, software, professional services, third-party service contracts, maintenance contracts, managed services, and financing of hardware and software. Financing revenue pertaining to the portion of an arrangement containing a lease is recognized in accordance with ASC 842. Financing revenue related to the lease is recorded in revenue as equipment leasing is part of our operations. Third-party service contracts are evaluated to determine whether such service revenue should be recorded as gross or net sales and whether over time or at point in time. HPP Segment Revenue HPP segment revenue is derived from the sale of integrated hardware and software, maintenance, and other services through the Multicomputer, Myricom, and ARIA product lines. Myricom revenue is derived from the sale of products, which are comprised of both hardware and embedded software which is essential to the products’ functionality, and post contract maintenance and support. Post contract maintenance and support is considered immaterial in the context of the contract and therefore is not a separate performance obligation. Multicomputer revenue is derived from the sale of hardware, software, extended warranties, royalties, and repair services. ARIA Zero Trust Gateway (“AZT”) revenue contains two performance obligations: a software license and post contract support. The transaction price is generally fixed consideration and allocated based on relative stand-alone selling price. Software license revenue is recognized at a point in time, generally when the license is made available to the customer.

Significant Judgments The input method using labor hours expended relative to the total expected hours is used to recognize revenue for professional services. Only the hours that depict our performance toward satisfying a performance obligation are used to measure progress. An estimate of hours for each professional service agreement is made at the beginning of each contract based on prior experience and monitored throughout the performance of the services. This method is most appropriate as it depicts the measure of progress towards satisfaction of the performance obligation. A financing component exists when at contract inception the period between the transfer of a promised good and/or service to the customer differs from when the customer pays for the good and/or service. As a practical expedient, we have elected not to adjust the amount of consideration for effects of a significant financing component when it is anticipated the promised good or service will be transferred and the subsequent payment will be one year or less. ​ Certain contracts contain a financing component including managed services contracts with financing of hardware and software. The interest rate used reflects the approximate interest rate consistent with a separate financing transaction with the customer at the inception of the agreement. Revenues from arrangements which include financing are allocated considering relative standalone selling prices of lease and non-lease components within the agreement. The lease component includes hardware, which is subject to ASC 842, Leases Revenue from Contracts with Customers ​ When product and non-managed services are sold together, the allocation of the transaction price to each performance obligation is calculated based on the estimated relative selling price or a budgeted cost-plus margin approach, as appropriate. Due to the complex nature of these contracts, there is significant judgment in allocating the transaction price. These estimates are periodically reviewed by project managers, engineers, and other staff involved to ensure estimates remain appropriate. For items sold separately, including hardware, software, professional services, maintenance contracts, other services, and third-party service contracts, there is no allocation as there is one performance obligation. We recognize revenue from third-party service contracts as either gross sales or net sales depending on whether we are acting as a principal party to the transaction or simply acting as an agent or broker based on control and timing. We are a principal if we control the good or service before that good or service is transferred to the customer. We record revenue as gross when we are a principal party to the arrangement and net of cost when we are acting as a broker or agent for a third party. Under gross sales recognition, the entire selling price is recorded in revenue and our cost to the third-party service provider or vendor is recorded in cost of sales. Under net sales recognition, the cost to the third-party service provider or vendor is recorded as a reduction to revenue resulting in net sales equal to the gross profit on the transaction. Third-party service contracts are sold in different combinations with hardware, software, and services. When we are an agent, revenue is typically recorded at a point in time. When we are the principal, revenue is recognized over the contract term. We have concluded we are the agent in sales of third-party maintenance, software or hardware support, and certain security software that is sold with integral third-party delivered software maintenance that includes critical updates. Contract Assets and Liabilities When we have performed work but do not have an unconditional right to payment, a contract asset is recorded. When we have the right to bill a customer, accounts receivable is recorded as an unconditional right exists. Current contract assets were $0.8 million and $0.9 million as of June 30, 2024 and September 30, 2023, respectively. The current portion is recorded in other current assets on the condensed consolidated balance sheets. There were no noncurrent contract assets as of June 30, 2024 and September 30, 2023. The difference in the balances is due to regular timing differences between when work is performed and having an unconditional right to payment. Contract liabilities arise when payment is received before we transfer a good or service to the customer. Current contract liabilities were $1.6 million and $1.9 million as of June 30, 2024 and September 30, 2023, respectively. The current portion of contract liabilities is recorded in deferred revenue on the condensed consolidated balance sheets. There were no long-term contract liabilities as of June 30, 2024 and September 30, 2023, respectively. Revenue recognized for the three and nine months ended June 30, 2024 that was included in contract liabilities as of September 30, 2023 was $0.2 million and $1.3 million, respectively. Contract Costs Incremental costs of obtaining a contract involving customer transactions where the revenue and the related transfer of goods and services are equal to or less than a one year period, are expensed as incurred, utilizing the practical expedient in ASC 340-40-25-4 Current capitalized contract costs are within the other current assets on the condensed consolidated balance sheets as of June 30, 2024 and September 30, 2023. The portion of current capitalized costs were $190 thousand and $172 thousand as of June 30, 2024 and September 30, 2023, respectively. There are no noncurrent capitalized costs on the condensed consolidated balance sheets as these commissions are paid annually even when the contract extends beyond a one year period. The amount of incremental costs amortized for the three months ended June 30, 2024 and 2023 were $122 thousand and $103 thousand, respectively. The amount of incremental costs amortized for the nine months ended June 30, 2024 and 2023 were $351 thousand and $302 thousand, respectively and is recorded in selling, general, and administrative expenses. There was no impairment related to incremental costs capitalized during the nine months ended June 30, 2024 and 2023. Costs to fulfill a contract are capitalized when the costs are related to a contract or anticipated contract, generate or enhance resources that will be used in satisfying performance obligations in the future, and costs are recoverable. Costs to fulfill a contract are related to the TS portion of the business and involve activities performed before managed services can be completed. The were no current capitalized costs as of June 30, 2024 or September 30, 2023. Other Projects are typically billed upon completion or at certain milestones. Product and services are typically billed when shipped or as services are being performed. Payment terms are typically 30 days to pay in full except in Europe where it could be up to 90 days. Most of our contracts are less than one year. There are certain contracts that contain a financing component. See Note 5 Financing receivables, net We have certain contracts that have an original term of more than one year. The royalty agreement is longer than one year, but not included in the table below as the royalties are sales-based. Managed service contracts are generally longer than one year and revenue is recognized ratably over the contract term.

This involves amounts due reflecting sales whose payment terms exceed one year. This financing is separate from agreements with a leasing component, see Note 7 Leases The Company assigns an internal risk rating to each customer at inception, which groups customers into a portfolio based off this risk rating. A risk rating is assigned by analyzing a customer’s financial statements and the latest Fitch rating if publicly available as well as recent payment activity. The credit quality of customers is continually monitored by these items. Accounts rated low risk have the equivalent of a Fitch rating of BBB– or higher, while accounts rated moderate risk have the equivalent of BB. The Company does not offer financing for customers where the risk is classified as higher, which would be lower than the equivalent of a BB Fitch rating. Financing receivables, net carry an average weighted average interest rate of 7.1%, which reflects the approximate interest rate consistent with a separate financing transaction with the customer at the inception of the agreement. The amount of interest income earned from sales whose payment terms exceed one year for the three months ended June 30, 2024 and 2023 was $177 thousand and $234 thousand, respectively. The amount of interest income earned from sales whose payment terms exceed one year for the nine months ended June 30, 2024 and 2023 was $528 thousand and $605 thousand, respectively.

The US supplemental retirement plans have life insurance policies which are not plan assets but were purchased by the Company as a vehicle to fund the costs of the plan. The Company also provides for officer death benefits through post-retirement plans to certain current officers of the Company in the US All the Company’s defined benefit plans are closed to newly hired employees and have been since September 2009. The Company funds its pension plans in amounts sufficient to meet the requirements set forth in applicable employee benefits laws and local tax laws. Liabilities for amounts in excess of these funding levels are accrued and reported in the condensed consolidated balance sheets. The Company’s pension plan in the UK is the only plan with plan assets. The plan assets consist of an investment in a commingled fund which in turn comprises a diversified mix of assets including corporate equity securities, government securities and corporate debt securities. The components of net periodic benefit costs related to the US and UK plans are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ ​ 2024 ​ 2023 ​ U.K. U.S. Total U.K. U.S. Total ​ ​ (Amounts in thousands) Pension: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest cost ​ $ 112 ​ $ 2 ​ $ 114 ​ $ 110 ​ $ 4 ​ $ 114 Expected return on plan assets ​ (149) ​ — ​ (149) ​ (148) ​ — ​ (148) Amortization of past service costs ​ ​ 2 ​ ​ — ​ ​ 2 ​ ​ 1 ​ ​ — ​ ​ 1 Amortization of net gain ​ — ​ (1) ​ (1) ​ — ​ (1) ​ (1) Net periodic (benefit) cost ​ $ (35) ​ $ 1 ​ $ (34) ​ $ (37) ​ $ 3 ​ $ (34) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Post Retirement: ​ ​ ​ ​ ​ ​ Service cost ​ $ — ​ $ 5 ​ $ 5 ​ $ — ​ $ 6 ​ $ 6 Interest cost ​ — ​ 16 ​ 16 ​ — ​ 14 ​ 14 Amortization of net gain ​ — ​ (43) ​ (43) ​ — ​ (50) ​ (50) Net periodic benefit ​ $ — ​ $ (22) ​ $ (22) ​ $ — ​ $ (30) ​ $ (30) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine months ended June 30, ​ ​ 2024 ​ 2023 ​ U.K. U.S. Total U.K. U.S. Total ​ ​ (Amounts in thousands) Pension: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest cost ​ $ 333 ​ $ 8 ​ $ 341 ​ $ 321 ​ $ 11 ​ $ 332 Expected return on plan assets ​ (445) ​ — ​ (445) ​ (430) ​ — ​ (430) Amortization of past service costs ​ ​ 6 ​ ​ — ​ ​ 6 ​ ​ 5 ​ ​ — ​ ​ 5 Amortization of net gain ​ — ​ (4) ​ (4) ​ — ​ (3) ​ (3) Net periodic (benefit) cost ​ $ (106) ​ $ 4 ​ $ (102) ​ $ (104) ​ $ 8 ​ $ (96) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Post Retirement: ​ ​ ​ ​ ​ ​ Service cost ​ $ — ​ $ 17 ​ $ 17 ​ $ — ​ $ 18 ​ $ 18 Interest cost ​ — ​ 48 ​ 48 ​ — ​ 46 ​ 46 Amortization of net gain ​ — ​ (129) ​ (129) ​ — ​ (147) ​ (147) Net periodic benefit ​ $ — ​ $ (64) ​ $ (64) ​ $ — ​ $ (83) ​ $ (83) ​ The fair value of the assets held by the UK pension plan by asset category are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Values as of ​ ​ June 30, 2024 ​ September 30, 2023 ​ ​ Fair Value Measurements Using Inputs Considered as ​ Fair Value Measurements Using Inputs Considered as Asset Category Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 ​ ​ (Amounts in thousands) Cash on deposit ​ $ 64 ​ $ 64 ​ $ — ​ $ — ​ $ 428 ​ $ 428 ​ $ — ​ $ — Fixed income ​ ​ 9,565 ​ ​ 8,016 ​ ​ 1,549 ​ ​ — ​ ​ 8,703 ​ ​ 7,251 ​ ​ 1,452 ​ ​ — Equity ​ 881 ​ 247 ​ ​ 634 ​ ​ — ​ 903 ​ 266 ​ ​ 637 ​ ​ — Total plan assets ​ $ 10,510 ​ $ 8,327 ​ $ 2,183 ​ $ — ​ $ 10,034 ​ $ 7,945 ​ $ 2,089 ​ $ — ​ ​

The estimated annualized effective income tax rate for the three months ended June 30, 2024 was 19.2%, excluding the impacts of the UK entity which continues to experience losses and maintains a full valuation allowance, compared to the estimated annualized effective income tax rate of 51.7% for the same period of 2023. The difference between our effective income tax rate and the U.S. federal statutory rate for the three months ending June 30, 2024 are the impact of state taxes and tax credits that we expect to be able to utilize against federal and state taxes. During the 3 months ending June 30, 2023, we released a significant portion of the valuation allowance against our U.S. deferred tax assets and switched from using the discrete effective tax rate method to calculate income taxes to the annualized effective tax rate method, resulting in the shift in the effective tax rate during the period. ​ The effective tax rate for the three months ended June 30, 2024 was 29.3%, excluding the UK as previously mentioned, driven by excess tax benefits on restricted stock awards vesting during the period. The effective tax rate for the three months ended June 30, 2023 was (201.9)%, excluding the UK, which was primarily driven by the release of a significant portion of the valuation allowance against our deferred tax assets in the U.S. ​ An income tax expense of $73 thousand was recorded for the nine months ended June 30, 2024 compared to an income tax benefit of $1.5 million in the same period of 2023. The estimated annualized effective income tax rate for the nine months ended June 30, 2024 was 19.2%, excluding the impacts of the UK entity which continues to experience losses and maintains a full valuation allowance, compared to the estimated annualized effective income tax rate of 22.0% for the nine months ended June 30, 2023. The difference between our effective income tax rate and the U.S. federal statutory rate for the three months ending June 30, 2024 and the same period of 2023 are the impact of state taxes and tax credits that we expect to be able to utilize against federal and state taxes. ​ The effective tax rate for the nine months ended June 30, 2024 was 4.9%, excluding the UK as previously mentioned, driven by excess tax benefits on restricted stock awards vesting during the period.

Fair Value of Financial Assets and Liabilities	13. Fair Value of Financial Assets and Liabilities Under the fair value standards fair value is based on the exit price and defined as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement should reflect all the assumptions that market participants would use in pricing an asset or liability. A fair value hierarchy is established in the authoritative guidance outlined in three levels ranking from Level 1 to Level 3 with Level 1 being the highest priority. ​ Level 1: observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets ​ Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly ​ Level 3: unobservable inputs (e.g., a reporting entity’s or other entity’s own data) ​ The Company had no assets or liabilities measured at fair value on a recurring (except our pension plan assets and whole life insurance policies, see Note 10 Pension and Retirement Plans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To estimate fair value of the financial instruments below, quoted market prices are used when available and classified within Level 1. If this data is not available, we use observable market-based inputs to estimate fair value, which are classified within Level 2. If the preceding information is unavailable, we use internally generated data to estimate fair value which is classified within Level 3. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 2024 ​ ​ As of September 30, 2023 ​ ​ ​ ​ ​ ​ Carrying Amount ​ ​ Fair Value ​ ​ Carrying Amount ​ ​ Fair Value ​ Fair Value Level ​ Reference ​ ​ (Amounts in thousands) ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents $ 28,891 ​ $ 28,891 ​ $ 25,217 ​ $ 25,217 ​ 1 ​ Condensed Consolidated Balance Sheets Accounts receivable, net ​ 9,436 ​ ​ 9,436 ​ ​ 12,955 ​ ​ 12,955 ​ 2 ​ Note 4 Financing receivables, net ​ 12,428 ​ ​ 12,428 ​ ​ 11,395 ​ ​ 11,395 ​ 3 ​ Note 5 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accounts payable and accrued expenses and other long-term liabilities* ​ 4,499 ​ ​ 4,499 ​ ​ 3,429 ​ ​ 3,429 ​ 3 ​ Note 8 Line of Credit ​ 829 ​ ​ 829 ​ ​ 1,515 ​ ​ 1,515 ​ 2 ​ Note 9 Note payable ​ — ​ ​ — ​ ​ 449 ​ ​ 449 ​ 3 ​ Note 9 ​ *Original maturity over one year ​ Cash and cash equivalents Carrying amount approximated fair value. ​ Accounts and long-term receivable with original maturity over one year Fair value was estimated by discounting future cash flows based on the current rate with similar terms. ​ Line of credit The fair value of our line of credit is based on borrowing rates currently available to a market participant for loans with similar terms or maturity. The carrying amount of our outstanding revolving line of credit approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. No interest accrues under the inventory line of credit when advances are paid within terms. ​ Notes Payable Fair value was estimated by discounting future cash flows based on the current rate the Company could get in another transaction with similar terms based on historical information. ​ Fair value of accounts receivable with an original maturity of one year or less and accounts payable was not materially different from their carrying values as of June 30, 2024 and September 30, 2023.

Basis of Presentation and New Significant Accounting Policy
Basis of Presentation	Basis of Presentation The accompanying interim condensed consolidated financial statements have been prepared by the Company and reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. All adjustments were of a normal recurring nature. Certain information and footnote disclosures normally included in the annual consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States, have been omitted. Accordingly, the Company believes that although the disclosures are adequate to make the information presented not misleading, the unaudited condensed consolidated financial statements should be read in conjunction with the notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023.
Presentation - sales whose payment terms exceed one year	Presentation – sales whose payment terms exceed one year Effective in fiscal year 2024 sales whose payment terms exceed one year is now presented as “Financing receivables, net of allowances” on the Consolidated Balance Sheets rather than being combined with Accounts receivable, net of allowances. The financial statement line item Long-term receivable is now labeled as “Financing receivables due after one year, net of allowances.” These changes are reflected retrospectively as of September 30, 2023. This change was made to provide more detail on the balance sheet related to these receivables and align with our notes to the unaudited condensed consolidated financial statements.
Presentation - two-for-one stock split	Presentation – two-for-one stock split On February 21, 2024, the Board of Directors of CSP Inc. approved an amendment to the Company’s Articles of Organization to increase the total number of its authorized shares of Common Stock, par value $0.01 , from 7,500,000 shares to 9,753,900 shares (the “Amendment”). No shareholder approval was required under the Massachusetts Business Corporation Act with respect to the Amendment. The Amendment became effective upon filing with the Secretary of the Commonwealth of Massachusetts on February 21, 2024. ​ On June 26, 2024, the stockholders of CSP, Inc. approved an amendment to the Company's Articles of Organization, as amended (the "Articles of Organization"), to increase the number of authorized shares of Common Stock from 9,753,900 to 20,000,000 (the "Amendment"). On June 26, 2024, the Company filed an Articles of Amendment to the Articles of Organization with the Secretary of the Commonwealth of Massachusetts to effect the Amendment, which became effective immediately upon such filing. This amendment is included as Exhibit 3.1 and is incorporated herein by reference. ​ On February 21, 2024, the Company announced its Board of Directors approved and declared a two -for-one stock split to be effected in the form of a 100% stock dividend. The stock dividend was paid on March 20, 2024 to shareholders of record as of the close of business on March 6, 2024. In accordance with ASC 505 Equity , specifically ASC 505-20-25-3 through ASC 505-20-25-6 , we have determined this had a material effect on reducing share market value and therefore was treated this event as a stock split for accounting purposes. All common shares and per share amounts contained in these condensed interim financial statements and notes have been retrospectively restated to reflect this two -for-one stock split in the form a 100% dividend in accordance with ASC 260 Earnings Per Share , specifically ASC 260-10-55-12 .
Use of Estimates	Use of estimates The preparation of condensed consolidated interim financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. These estimates and assumptions are related to the allowance for credit losses for accounts receivable and financing receivables, reserves for inventory obsolescence, the impairment assessment of intangible assets, right-of-use assets and lease liabilities, and the calculation of standalone selling price for revenue recognition, the calculation of liabilities related to deferred compensation and retirement plans and the calculation of income tax liabilities. Actual results may differ from those estimates under different assumptions or conditions.
Recently Adopted Accounting Pronouncements	Significant Accounting Policies Except for the change in certain accounting policies upon adoption of the accounting standard described below, there have been no significant changes to the Company's significant accounting policies described in PART II, Item 8, Note 1 Summary of Significant Accounting Policies Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting standards update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) The Company adopted ASU 2016-13 (the “new CECL standard”) as of October 1, 2023 using the modified retrospective method, with a cumulative-effect adjustment to the opening balance of Shareholders’ equity as of October 1, 2023. The adoption primarily impacted the estimation of our Allowance for credit losses for Accounts receivable and Financing receivables. Additionally, it affected allowance for credit losses of contract assets with effects being immaterial. The total impact recorded on our initial adoption of ASU 2016-13 as of October 1, 2023 included an increase of Accounts receivable, net of $67k and a decrease of Financing receivables, net in the amount of $82k with the total adjustment decreasing retained earnings of $15k. For the accounting policies adopted and details of impacts from adoption refer to Note 4 - Accounts receivable, net Note 5 - Financing receivables, net ​ Recently Accounting Pronouncements Not Yet Adopted Improvements to Reportable Segment Disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), which requires disclosure of incremental segment information on an annual and interim basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures.
