NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

The unaudited consolidated financial statements of Harvard Bioscience, Inc. and its wholly-owned subsidiaries (collectively, the “Company”) as of March 31, 2024 and for the three months ended March 31, 2024 and 2023, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The December 31, 2023 consolidated balance sheet was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10 -K for the fiscal year ended December 31, 2023.

In the opinion of management, all adjustments, which include normal recurring adjustments necessary to present a fair statement of financial position as of March 31, 2024, results of operations and comprehensive income (loss) and cash flows for the three months ended March 31, 2024 and 2023, as applicable, have been made. The results of operations for the three months ended March 31, 2024, are not necessarily indicative of the operating results for the full fiscal year or any future periods.

The accounting policies underlying the accompanying unaudited consolidated financial statements are set forth in Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10 -K for the year ended December 31, 2023. There have been no material changes in the Company’s significant accounting policies during the three months ended March 31, 2024.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use of management estimates. Such estimates include the determination and establishment of certain accruals and provisions, including those for income taxes, credit losses on receivables, and defined benefit pension obligations. Estimates are also required to evaluate the value for inventories reported at lower of cost or net realizable value, stock-based compensation expense, and the recoverability of long-lived and intangible assets, including goodwill. On an ongoing basis, the Company reviews its estimates based upon currently available information. Actual results could differ materially from those estimates.

Other Operating Expenses

Other operating expenses for the three months ended March 31, 2024 included a fee of $ 0.5 million in connection with the receipt of employee retention credits (See Note 5 ) and an estimated loss of $ 0.5 million related to an unclaimed property audit (See Note 13 ).

Recently Issued Accounting Pronouncements Yet to Be Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023 - 09, Income Taxes (Topic 740 ): Improvements to Income Tax , which enhances disclosures related to the effective tax rate reconciliation, income taxes paid, as well as other disclosures. The new standard impacts footnote disclosures and is effective for the Company’s annual financial statements for the year ended December 31, 2025. The Company is currently evaluating the potential impact of adopting ASU No. 2023 - 09 will have on the disclosures in its consolidated financial statements.

1. Earnings (Loss) per Share

Basic earnings (loss) per share (EPS) is calculated by dividing net income (loss) by the number of weighted average shares of common stock outstanding during the period. The calculation of diluted earnings per share assumes conversion of stock options and restricted stock units into common stock using the treasury method.

The following table summarizes the calculation of basic and diluted net income (loss) per share of common stock:

Table of Contents

The Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES Act”) provided an employee retention credit (“ERC”) that was a refundable tax credit against certain employer taxes. The Company has elected to account for the credit as a government grant. As there is no authoritative guidance under U.S. GAAP on accounting for grants to for-profit business entities from government entities, the Company accounts for government assistance by analogy to International Accounting Standards Topic 20, Accounting for Government Grants and Disclosure of Government Assistance (IAS 20 ). Under IAS 20, government grants are recognized when there is reasonable assurance that the grant will be received and that all conditions related to the grant will be met.

The Company received an ERC refund of $ 3.2 million during the quarter ended March 31, 2024. Due to the subjectivity of the credit, the Company has included the refund received in other current liabilities in the consolidated balance sheet as of March 31, 2024, subject to a determination that the refund is recognizable under IAS 20.

The Company engaged a professional services firm under a commission fee arrangement to assist with determining program eligibility and in accumulating the necessary support that was used as a basis in the filing. During the three months ended March 31, 2024, the Company paid a fee of $ 0.5 million for these services, which is included in other operating expenses in the consolidated statement of operations.

1. Marketable Equity Securities

In April 2023, the Company obtained shares of common stock of Harvard Apparatus Regenerative Technologies, Inc. (“HRGN” formerly known as Biostage, Inc.) in connection with settlement of indemnification obligations related to litigation which occurred during the year ended December 31, 2022. These shares had an estimated fair value of $ 1.7 million and $ 3.5 million, as of March 31, 2024, and December 31, 2023, respectively, and are included in the consolidated balance sheets as a component of other long-term assets.

The Company received cash proceeds of $ 0.5 million from the sale of HRGN shares sold during the three months ended March 31, 2024, which resulted in a realized loss on sale of $ 0.3 million. The Company incurred an unrealized loss of $ 1.0 million on HRGN shares held during the three months ended March 31, 2024. The Company determines the fair value of its HRGN common stock based on the closing price as quoted on the OTCQB Marketplace at the reporting date. Due to HRGN’s limited operating history, its overall financial condition and the limited trading volumes and liquidity of its common stock, the value of the Company’s investment in this common stock could fluctuate considerably or become worthless.

1. Leases

The Company has noncancelable operating leases for offices, manufacturing facilities, warehouse space, automobiles and equipment expiring at various dates through 2030.

The components of lease expense for the three months ended March 31, 2024 and 2023, were as follows:

(in thousands)	Three Months Ended March 31, — 2024	2023
Operating lease cost	$ 511	$	543
Short-term lease cost	50		67
Sublease income	( 25	)	( 25	)

The Company maintains a Credit Agreement (as amended, the “Credit Agreement”) with Citizens Bank, N.A., Wells Fargo Bank, National Association, and First Citizens Bank & Trust Company (together, the “Lenders”). The Credit Agreement provides for a term loan of $ 40.0 million and a $ 25.0 million senior revolving credit facility (including a $ 10.0 million sub-facility for the issuance of letters of credit and a $ 10.0 million swingline loan sub facility) (collectively, the “Credit Facility”). The Company’s obligations under the Credit Agreement are guaranteed by certain of the Company’s direct, domestic wholly-owned subsidiaries; none of the Company’s direct or indirect foreign subsidiaries has guaranteed the Credit Facility. The Company’s obligations under the Credit Agreement are secured by substantially all of the assets of Harvard Bioscience, Inc., and each guarantor (including all or a portion of the equity interests in certain of the Company’s domestic and foreign subsidiaries). The Credit Facility matures on December 22, 2025. Issuance costs of $ 1.4 million are amortized over the contractual term to maturity date on a straight-line basis, which approximates the effective interest method. Available and unused borrowing capacity under the revolving line of credit was $ 4.4 million as of March 31, 2024 based on the Credit Agreement, as amended pursuant to the March 2024 Amendment as described below. Total revolver borrowing capacity is limited by the consolidated net leverage ratio as defined under the amended Credit Agreement.

Borrowings under the Credit Facility will, at the option of the Company, bear interest at either (i) a rate per annum based on the Secured Overnight Financing Rate (“SOFR”) for an interest period of one, two, three or six months, plus an applicable interest rate margin determined as provided in the Credit Agreement, (a “SOFR Loan”), or (ii) an alternative base rate plus an applicable interest rate margin, each as determined as provided in the Credit Agreement (an “ABR Loan”). SOFR interest under the Credit Agreement is subject to applicable market rates and a floor of 0.50 %. The alternative base rate is based on the Citizens Bank prime rate or the federal funds effective rate of the Federal Reserve Bank of New York and is subject to a floor of 1.0 %. The applicable interest rate margin varies from 2.0 % per annum to 3.25 % per annum for SOFR Loans, and from 1.5 % per annum to 3.0 % per annum for ABR Loans, in each case depending on the Company’s consolidated net leverage ratio and is determined in accordance with a pricing grid set forth in the Credit Agreement. There are no prepayment penalties in the event the Company elects to prepay and terminate the Credit Facility prior to its scheduled maturity date, subject to SOFR Loan breakage and redeployment costs in certain circumstances.

The effective interest rate on the Company borrowings for the three months ended March 31, 2024 and 2023, was 7.7 % and 7.9 %, respectively, and the weighted average interest rate as of March 31, 2024, net of the effect of the Company’s interest rate swaps, was 7.4 %. The carrying value of the debt approximates fair value because the interest rate under the obligation approximates market rates of interest available to the Company for similar instruments.

As of March 31, 2024, the term loan requires quarterly installments of $ 1.0 million with a balloon payment at maturity. Furthermore, within ninety days after the end of the Company’s fiscal year, the term loan may be permanently reduced pursuant to certain mandatory prepayment events including an annual “excess cash flow sweep”, as defined in the agreement; provided that, in any fiscal year, any voluntary prepayments of the term loan shall be credited against the Company’s “excess cash flow” prepayment obligations on a dollar-for-dollar basis for such fiscal year. As of December 31, 2023, the current portion of long-term debt included amounts due under the excess cash flow sweep of $ 2.0 million which was paid on March 29, 2024. Amounts outstanding under the revolving credit facility can be repaid at any time but are due in full at maturity.

The Credit Agreement includes customary affirmative, negative, and financial covenants binding on the Company. The negative covenants limit the ability of the Company, among other things, to incur debt, incur liens, make investments, sell assets and pay dividends on its capital stock. The financial covenants include a maximum consolidated net leverage ratio and a minimum consolidated fixed charge coverage ratio. The Credit Agreement also includes customary events of default.

In March, 2024, the Company entered into an amendment to the Credit Agreement (the “March 2024 Amendment”) pursuant to which the Lenders and administrative agent modified the definition of Consolidated EBITDA used in the calculation of certain financial covenants to adjust for charges related to the ongoing abandoned property audit (See Note 13 ) and commission fees expected to be paid in connection with the employee retention credit filings (See Note 5 ). The Company was in compliance with the covenants of the Credit Agreement, as amended, as of March 31, 2024.

1. Derivatives

In February 2023, the Company entered into an interest rate swap contract to improve the predictability of cash flows from interest payments related to its variable, SOFR-based debt. The swap contract had a notional amount of $ 25.9 million as of March 31, 2024 and matures on December 22, 2025. This swap contract effectively converts the SOFR-based variable portion of the interest payable under the Credit Agreement into fixed-rate debt at an annual rate of 4.75 %. The swap contract does not impact the additional interest related to the applicable interest rate margin as discussed above in Note 8, Long-Term Debt. The swap contract is considered an effective cash flow hedge, and as a result, net gains or losses are reported as a component of other comprehensive income (“OCI”) in the consolidated financial statements and are reclassified as net income when the underlying hedged interest impacts earnings. An assessment is performed quarterly to evaluate the ongoing hedge effectiveness.

• Amount not significant.

The Company uses the market approach technique to value its financial liabilities. The Company’s financial assets and liabilities carried at fair value include, when applicable, investments in common stock and derivative instruments used to hedge the Company’s interest rate risks. The fair value of the Company’s investment in HRGN common stock (See Note 6 ) was based on the closing price per the OTCQB Marketplace at the reporting date. The fair value of the Company’s interest rate swap agreements was based on SOFR yield curves at the reporting date.

1. Stock-Based Compensation

Stock-based compensation expense for the three months ended March 31, 2024 and 2023 was allocated as follows:

Unvested shares related to market-based and performance-based vesting conditions are reflected at 100 % of their target vesting amount in the table above. Actual vesting could range from zero up to 150 % of their target amounts.

Performance-based RSU awards are contingent on the achievement of certain performance metrics. Compensation cost associated with performance-based RSUs are recognized based on the estimated number of shares that the Company ultimately expects will be earned. If the estimated number of shares to be earned is revised in the future, then stock-based compensation expense will be adjusted accordingly.

Stock option activity for the three months ended March 31, 2024 was as follows:

Outstanding and Exerciseable at December 31, 2023	924,067	$	3.37	Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value (in thousands)
Exercised	( 3,899	)	3.96
Outstanding and Exerciseable at March 31, 2024	920,168	$	3.37	3.2 years	$ 964

The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the Company’s closing stock price of $ 4.24 as of the end of the reporting period, which would have been received by the option holders had all option holders exercised their options as of that date. The aggregate intrinsic value of options exercised during the three months ended March 31, 2024, was not significant.

1. Income Tax

The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income in each tax jurisdiction in which the Company operates and the development of tax planning strategies during the year. In addition, as a global commercial enterprise, the Company’s tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits and reviews and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

Income tax expense was $ 0.2 million and $ 0.6 million for the three months ended March 31, 2024 and 2023, respectively. The Company’s effective tax rate of ( 4.7 %) for the three months ended March 31, 2024 was lower than the U.S. statutory rate primarily due to the inclusion of non-deductible executive compensation and changes in valuation allowances associated with the Company’s assessment of the likelihood of the recoverability of deferred tax assets. The Company’s effective tax rate of 48.5 % for the three months ended March 31, 2023 was higher than the U.S. statutory rate primarily due to a Global Intangible Low-Taxed Income (“GILTI”) inclusion to taxable income and changes in valuation allowances. The Company has valuation allowances against substantially all of its tax credit carryforwards.

1. Commitments and Contingent Liabilities

The Company is involved in various claims and legal proceedings arising in the ordinary course of business. After consultation with legal counsel, the Company has determined that the ultimate disposition of such proceedings is not likely to have a material adverse effect on its business, financial condition, results of operations or cash flows. Although unfavorable outcomes in the proceedings are possible, the Company has not accrued loss contingencies relating to any such matters as they are not considered to be probable and reasonably estimable. If one or more of these matters are resolved in a manner adverse to the Company, the impact on the Company’s business, financial condition, results of operations and cash flows could be material.

In addition, the Company has entered into indemnification agreements with its directors and officers. It is not possible to determine the maximum potential liability amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. The Company has not recorded any liability for costs related to contingent indemnification obligations as of March 31, 2024.

The Company is subject to unclaimed property laws in the ordinary course of its business. State escheat laws generally require entities to report and remit abandoned and unclaimed property to the state. Failure to timely report and remit the property can result in assessments that could include interest and penalties, in addition to the payment of the escheat liability itself. The Company is currently undergoing an unclaimed property audit. Based on the Company’s evaluation of the current stage of the audit, the Company accrued $ 0.5 million of loss contingencies during the three months ended March 31, 2024, which has been included in other operating expenses in the consolidated statement of operations.

1. Product Line Disposition

In February 2023, the Company sold its Hoefer product line for $ 0.5 million. The carrying value of assets sold was $ 0.1 million resulting in a gain on disposition of $ 0.4 million which was recorded in Other income, net in the consolidated statement of operations for the three months ended March 31, 2023. Revenue and gross profit of this disposed product line included in the condensed consolidated statement of operations for the three months ended March 31, 2023 were not significant.

Overview

Harvard Bioscience, Inc., a Delaware corporation, is a leading developer, manufacturer and seller of technologies, products and services that enable fundamental advances in life science applications, including research, pharmaceutical and therapy discovery, bioproduction and preclinical testing for pharmaceutical and therapy development. Our products and services are sold globally to customers ranging from renowned academic institutions and government laboratories to the world’s leading pharmaceutical, biotechnology and contract research organizations (“CROs”). With operations in the United States, Europe and China, we sell through a combination of direct and distribution channels to customers around the world.

Trends and Developments

Our business is affected by global and regional economic trends and uncertainties. The global economy has recently experienced increasing uncertainty as a result of developments including inflationary pressure, higher interest rates, fluctuations in exchange rates, economic conditions in China, and the events in Ukraine and the Middle East. Our business has also been affected by the softening of certain international markets, especially in China and the Asia-Pacific region, as well as by delays in government funding for certain customers. Our business has been affected by a reduced demand from our biotechnology and pharmaceutical company customers, due principally to the increased cost of capital and a reduction in spending following the COVID-19 pandemic.

If these trends are prolonged or are more severe, or if the recovery is less robust or takes longer than anticipated, our business, results of operations, and cash flow may be materially impacted.

Revenues

Revenues decreased $5.5 million, or 18.2%, to $24.5 million for the three months ended March 31, 2024, compared to $30.0 million for the three months ended March 31, 2023. The decrease in revenue was primarily due to the softening of worldwide demand, in particular in the Asia-Pacific region compared to a strong first quarter in 2023.

Gross profit

Gross profit decreased $3.5 million, or 19.5%, to $14.8 million for the three months ended March 31, 2024 compared with $18.3 million for the three months ended March 31, 2023, primarily due to the decrease in revenues. Gross margin decreased to 60.3% for the three months ended March 31, 2024, compared with 61.2% for the three months ended March 31, 2023. The decrease in gross margin was primarily the result of under-absorption of manufacturing overhead costs due to the decrease in revenues.

Sales and marketing expenses

Sales and marketing expenses of $5.9 million for the three months ended March 31, 2024, were comparable to the $6.0 million during the same period in 2023. Reduced variable compensation was offset by increased investments in personnel to support our growth strategy, product launches and travel costs related to industry trade shows.

General and administrative expenses

General and administrative expenses decreased $0.3 million, or 5.9%, to $6.0 million for the three months ended March 31, 2024, compared with $6.3 million for the three months ended March 31, 2023. The decrease was primarily due to reduced variable compensation.

Research and development expenses

Research and development expenses were $2.9 million for both the three months ended March 31, 2024, and March 31, 2023.

Amortization of intangible assets

Amortization of intangible assets included in operating expenses remained relatively unchanged and decreased to $1.3 million for the three months ended March 31, 2024, compared with $1.4 million for the three months ended March 31, 2023.

Other operating expenses

Other operating expenses for the three months ended March 31, 2023 included a fee of $0.5 million in connection with the receipt of employee retention credits and an estimated loss of $0.5 million related to an unclaimed property audit.

Interest expense

Interest expense decreased $0.2 million, or 22.9%, to $0.8 million for the three months ended March 31, 2024, compared with $1.0 million for the three months ended March 31, 2023. The decrease was primarily due to lower average borrowings during the period.

Loss on equity securities

As of March 31, 2024 and December 31, 2023 we held shares of common stock of HRGN with an estimated fair value of $1.7 million and $3.5 million, respectively. These shares were received in April 2023 in connection with settlement of indemnification obligations related to litigation which occurred during the year ended December 31, 2022. During the three months ended March 31, 2024, we recorded a loss of $1.3 million consisting of a realized loss of $0.3 million for shares sold and an unrealized loss of $1.0 million for shares held. We determine the fair value of our HRGN common stock based on the closing price as quoted on the OTCQB Marketplace at the reporting date. Due to HRGN’s limited operating history, its overall financial condition and the limited trading volumes and liquidity of its common stock, the value of our investment in this common stock could fluctuate considerably or become worthless.

Income tax expense

Income tax expense was $0.2 million and $0.6 million for the three months ended March 31, 2024 and 2023, respectively. The effective tax rates for the three months ended March 31, 2024 and 2023 were (4.7)% and 48.5%, respectively. The effective tax rate decreased in the first quarter of 2024 compared to 2023 due to a decrease in the GILTI inclusion. The effective tax rate for both the first quarters of 2024 and 2023 differed from the U.S. statutory rate primarily due to the inclusion of non-deductible executive compensation and changes in valuation allowances associated with our assessment of the likelihood of the recoverability of deferred tax assets.

Liquidity and Capital Resources

Our primary sources of liquidity are cash and cash equivalents, internally generated cash flow from operations and our revolving credit facility. Our expected cash outlays relate primarily to cash payments due under our Credit Agreement described below as well as capital expenditures, salaries, inventory, and capital expenditures.

We held cash and cash equivalents of $4.3 million at both March 31, 2024, and December 31, 2023. Borrowings outstanding were $36.1 million and $37.1 million as of March 31, 2024 and December 31, 2023, respectively.

We maintain a Credit Agreement which provides for a term loan of $40.0 million and a $25.0 million senior revolving credit facility both maturing on December 22, 2025. On March 28, 2024, we entered into an amendment to the Credit Agreement pursuant to which the Lenders and administrative agent modified the definition of Consolidated EBITDA used in the calculation of certain financial covenants to adjust for charges related to the ongoing abandoned property audit and commission fees expected to be paid in connection with our employee retention credit filings. We were in compliance with the covenants of the Credit Agreement, as amended, as of March 31, 2024. (See Note 8 to the Consolidated Condensed Financial Statements included in Part I, Item 1. of this report).

As of March 31, 2024, the weighted average interest rate on our borrowings, net of the effect of the interest rate swaps, was 7.4%, and the available and unused borrowing capacity was $4.4 million. Total revolver borrowing capacity is limited by our consolidated net leverage ratio as defined under the Credit Agreement, as amended.

Based on our current operating plans, we expect that our available cash, cash generated from current operations and debt capacity will be sufficient to finance current operations and capital expenditures for at least the next 12 months. This assessment includes consideration of our best estimates of the impact of macroeconomic conditions on our financial results described above. Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary as a result of a number of factors.

Cash provided by operating activities was $1.4 million and $1.8 million for the three months ended March 31, 2024 and 2023, respectively. Cash flow from operations for the three months ended March 31, 2024 was negatively impacted as a result of the decline in net income for the period adjusted for non-cash items and was positively impacted by the receipt of $3.2 million of employee retention credits.

Cash used in investing activities was $0.2 million for the three months ended March 31, 2024 and primarily consisted of capital expenditures in manufacturing and information technology infrastructure of $0.7 million partially offset by $0.5 million from the proceeds from the sale of marketable equity securities. Cash provided by investing activities was $0.3 million for the three months ended March 31, 2023 and primarily consisted of $0.5 million from proceeds of the sale our Hoefer product line partially offset by $0.2 million of capital expenditures.

Cash used in financing activities was $1.1 million and $2.9 million for the three months ended March 31, 2024 and 2023, respectively. During the three months ended March 31, 2024, debt outstanding under our credit facility decreased by $1.0 million, consisting of net borrowings under our revolver of $2.0 million, and payments of $3.0 million against the term loan. During the three months ended March 31, 2023, debt outstanding under our credit facility decreased by $2.8 million, consisting of net payments against our revolver of $1.0 million, and payments of $1.8 million against the term loan.

Impact of Foreign Currencies

Our international operations in some instances operate in a natural hedge, as we sell our products in many countries and a substantial portion of our revenues, costs and expenses are denominated in foreign currencies, primarily the euro and British pound.

During the three months ended March 31, 2024, changes in foreign currency exchange rates had an insignificant effect on our revenues and expenses. The gain (loss) associated with the translation of our foreign equity into U.S. dollars included as a component of other comprehensive income (loss) during the three months ended March 31, 2024 was a loss of $(0.8) million, compared to a gain of $0.8 million for the three months ended March 31, 2023. Currency exchange rate fluctuations included as a component of net income (loss) during the three months ended March 31, 2024, and March 31, 2023 were not significant.

Critical Accounting Policies

Evaluation of Disclosure Controls and Procedures

As of March 31, 2024, the end of the period covered by this report, our management, including our Chief Executive Officer and our Chief Financial Officer, reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Exchange Act). Based upon management's review and evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the SEC and is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the first quarter of fiscal 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud within the Company have been detected.
