The Company manufactures weighing instruments for use in laboratory, industrial, packaging, logistics and food retailing applications. The Company also manufactures several rela ted analytical inst ruments and provides automated chemistry solutions used in drug and chemical compound disco very and development.

The Company's primary manufacturing facilities are located in China, Germany, Switzerland, the United Kingdom and the United States. The Company's principal executive offices are located in Columbus, Ohio and Greifensee, Switzerland.
The accompanying interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include all entities in which the Company has control, which are its wholly-owned subsidiaries. The interim consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The interim 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 year ended December 31, 2020.
The accompanying interim consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as 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 financial statements were prepared using information reasonably available as of March 31, 2021 and through the date of this Report. Actual results may differ from those estimates due to uncertainty relating to the COVID-19 pandemic, as well as other factors.
All intercompany transactions and balances have been eliminated.

Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required.

Goodwill and Other Intangible Assets
Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount.
Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period to be benefited. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 “Business Combinations” and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 “Intangibles – Goodwill and Other” and ASC 360 “Property, Plant and Equipment.”
Other intangible assets consisted of the following:

Revenue Recognition
Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred based upon shipping terms. To the extent the Company’s arrangements have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. The related provisions for estimated returns and rebates are immaterial to the consolidated financial statements.
Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable stand-alone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install, and geographic location.
Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company generally does not sell software products without the related hardware instrument as the software is embedded in the product. The Company’s products typically require no significant production, modification, or customization of the hardware or software that is essential to the functionality of the products.
Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification, and preventative maintenance on a customer’s pre-defined equipment over the contract period.
Employee Termination Benefits
In situations where contractual termination benefits exist, the Company records accruals for employee termination benefits when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. All other employee termination arrangements are recognized and measured at their fair value at the communication date unless the employee is required to render additional service beyond the legal notification period, in which case the liability is recognized ratably over the future service period.
Share-Based Compensation
The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.6 million and $4.4 million of share-based compensation expense for the three months ended March 31, 2021 and 2020, respectively.
On May 6, 2021, the Company's shareholders approved the adoption of the Company's 2013 Equity Incentive Plan (Amended and Restated), and with the effect that approximately 0.9 million

additional shares of common stock will be added to the approximately 2.1 million shares that remained available under the plan prior to its amendment. In addition, shares subject to options granted under the Company's prior equity incentive plan that terminate without being exercised, will also be available for awards under the amended plan. The amended plan expires in 2031.
Research and Development
Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred.
Business Combinations and Asset Acquisitions
The Company accounts for business acquisitions under the accounting standards for business combinations utilizing the acquisition method of accounting. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. The determination of the values of the acquired assets and assumed liabilities, including goodwill and intangible assets, require significant judgement. Acquisition transaction costs are expensed when incurred.
In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net.
Recent Accounting Pronouncements
In March 2020, the FASB issued ASU 2020-04: Reference Rate Reform which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuance of LIBOR or another referenced rate. The guidance may be be applied to any applicable contract entered into before December 31, 2022. The Company is currently evaluating the impact of this guidance on the consolidated financial statements.
3.REVENUE
The Company disaggregates revenue from contracts with customers by product, service, timing of revenue recognition, and geography. A summary by the Company’s reportable segments follows:

Three months ended March 31, 2021 | U.S. Operations |  | Swiss Operations |  | Western European Operations |  | Chinese Operations |  | Other Operations |  | Total
Product Revenue | $ | 205,191 |  |  | $ | 30,167 |  |  | $ | 136,899 |  |  | $ | 143,325 |  |  | $ | 111,333 |  |  | $ | 626,915 |

A breakdown of net sales to external customers by geographic customer destination for the three months ended March 31 follows:

| 2021 |  | 2020
Americas | $ | 303,339 |  |  | $ | 264,824 |
Europe | 241,377 |  |  | 194,828 |
Asia / Rest of World | 259,674 |  |  | 189,510 |
Total | $ | 804,390 |  |  | $ | 649,162 |

The Company's global revenue mix by product category is laboratory (55% of sales), industrial (39% of sales) and retail (6% of sales). The Company's product revenue by reportable segment is proportionately similar to the Company's global mix except the Company's Swiss Operations is largely comprised of laboratory products, while the Company's Chinese Operations has a slightly higher percentage of industrial products. A breakdown of the Company’s sales by product category for the three months ended March 31 follows:

| 2021 |  | 2020
Laboratory | $ | 444,627 |  |  | $ | 357,091 |
Industrial | 310,777 |  |  | 252,355 |
Retail | 48,986 |  |  | 39,716 |
Total | $ | 804,390 |  |  | $ | 649,162 |

The payment terms in the Company’s contracts with customers do not exceed one year and therefore contracts do not contain a significant financing component. In most cases, after appropriate credit evaluations, payments are due in arrears and are recognized as receivables. Unbilled revenue is recorded when performance obligations have been satisfied, but not yet billed to the customer. Unbilled revenue as of March 31, 2021 and December 31, 2020 was $30.9 million and $22.6 million, respectively, and is included within accounts receivable. Deferred revenue and customer prepayments are recorded when cash payments are received or due in advance of the performance obligation being satisfied. Deferred revenue primarily includes prepaid service contracts, as well as deferred installation.

Changes in the components of deferred revenue and customer prepayments during the periods ended March 31, 2021 and 2020 are as follows:

| 2021 |  | 2020
Beginning balances as of January 1 | $ | 149,106 |  |  | $ | 122,489 |

Foreign currency translation | (3,556) |  |  | (2,530) |
Ending balance as of March 31 | $ | 180,330 |  |  | $ | 144,836 |

The Company generally expenses sales commissions when incurred because the contract period is one year or less. These costs are recorded within selling, general, and administrative expenses. The Company has not disclosed the value of unsatisfied performance obligations other than customer pre-payments and deferred revenue above as most contracts have an expected length of one year or less and amounts greater than one year are immaterial.
4. ACQUISITIONS
In March 2021, the Company acquired all the membership interests of Mayfair Technology, LLC, ("PendoTECH") a manufacturer and distributor of single-use sensors, transmitters, control systems and software for measuring, monitoring and data collection primarily in bioprocess applications. PendoTECH serves bio-pharmaceutical manufacturers and life science laboratories and is located in the United States. The initial cash payment was $185.0 million and the Company may be required to pay additional consideration of up to $20.0 million and other post-closing amounts. The additional consideration is based upon financial thresholds in 2022 and 2023. The estimated fair value of the contingent consideration obligation at the time of acquisition of $13.5 million was determined using a Monte Carlo simulation based on the Company's forecast of future financial results.
Goodwill recorded in connection with the acquisition totaled $93.7 million, which is deductible for tax purposes. Identified intangible finite-life assets acquired include customer relationships of $78.6 million, technology and patents of $21.7 million, trade name of $3.4 million, and other intangibles of $2.4 million. The Company used variations of the income statement approach in determining the fair value of the intangible assets acquired; specifically, the multi-period excess earnings method to determine the fair value of the customer relationships acquired and the relief from royalty method to determine the fair value of the technology and patents. The Company's determination of the fair value of the intangible assets acquired involved the use of significant estimates and assumptions principally related to revenue growth, royalty and customer attrition rates.
The identifiable finite-live intangible assets will be amortized on a straight-line basis over periods of 5 to 20 years and the annual aggregate amortization expense is estimated at $6.9 million. Net tangible assets acquired were $7.4 million and recorded at fair value in the consolidated financial statements. All of the acquired assets are included in the Company's U.S. Operations segment.
5. FINANCIAL INSTRUMENTS
The Company has limited involvement with derivative financial instruments and does not use them for trading purposes. The Company enters into certain interest rate swap agreements in order to manage its exposure to changes in interest rates. The amount of the Company's fixed obligation interest payments may change based upon the expiration dates of its interest rate swap agreements and the level and composition of its debt. The Company also enters into certain foreign currency forward contracts to limit the Company's exposure to currency fluctuations on the respective hedged items. For additional disclosures on derivative instruments regarding balance sheet location, fair value, and the amounts reclassified into other comprehensive income and the effective portions of the cash flow hedges, also see Notes 6 and 10 to the interim consolidated financial statements. As also mentioned in Note 8, the

Company has designated its euro-denominated debt as a hedge of a portion of its net investment in euro-denominated foreign subsidiary.
Cash Flow Hedges
In June 2019, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $50 million of borrowings under the Company's credit facility into synthetic Swiss franc debt, which allows the Company to effectively change the floating rate LIBOR-based interest payments, excluding the credit spread, to a fixed Swiss franc income of 0.82%. The swap began in June 2019 and matures in June 2023.
In June 2019, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $50 million of borrowings under the Company's credit facility into synthetic Swiss franc debt, which allows the Company to effectively change the floating rate LIBOR-based interest payments, excluding the credit spread, to a fixed Swiss franc income of 0.95%. The swap began in June 2019 and matures in June 2021.
In February 2019, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $50 million of borrowings under the Company's credit facility into synthetic Swiss franc debt which allows the Company to effectively change the floating rate LIBOR-based interest payments, excluding the credit spread to a fixed Swiss franc income of 0.78%. The swap began in February 2019 and matures in June 2021.
In 2015, the Company entered into an interest rate swap agreement designated as a cash flow hedge. The agreement is a swap which has the effect of changing the floating rate LIBOR-based interest payments associated with $100 million in borrowings under the Company's credit agreement to a fixed obligation of 2.25%. The swap began in February 2017 and matures in February 2022.
The Company's cash flow hedges are recorded gross at fair value in the consolidated balance sheet at March 31, 2021 and December 31, 2020, respectively. A derivative loss of $0.9 million based upon interest rates at March 31, 2021, is expected to be reclassified from other comprehensive income (loss) to earnings in the next twelve months. The cash flow hedges remain effective as of March 31, 2021.
Other Derivatives
The Company enters into foreign currency forward contracts in order to economically hedge short-term trade and non-trade intercompany balances largely denominated in Swiss franc, other major European currencies, and the Chinese Renminbi with its foreign businesses. In accordance with U.S. GAAP, these contracts are considered “derivatives not designated as hedging instruments.” Gains or losses on these instruments are reported in current earnings. The foreign currency forward contracts are recorded at fair value in the consolidated balance sheet at March 31, 2021 and December 31, 2020, as disclosed in Note 6. The Company recognized in other charges (income) a net gain of $12.5 million and net loss of $7.3 million during the three months ended March 31, 2021 and 2020, respectively, which offset the related transaction gains (losses) associated with these contracts. At March 31, 2021 and December 31, 2020, these contracts had a notional value of $805.4 million and $536.5 million, respectively.
6. FAIR VALUE MEASUREMENTS
At March 31, 2021 and December 31, 2020, the Company had derivative assets totaling $2.8 million and $2.2 million, respectively, and derivative liabilities totaling $12.4 million and $23.3 million, respectively. The Company has limited involvement with derivative financial instruments and therefore does not present all the required disclosures in tabular format. The fair values of the interest rate swap agreements, the cross currency swap agreements, and the foreign currency forward contracts that economically hedge short-term intercompany balances are estimated based upon inputs from current valuation information obtained from dealer quotes and priced with observable market assumptions and

appropriate valuation adjustments for credit risk. The Company has evaluated the valuation methodologies used to develop the fair values by dealers in order to determine whether such valuations are representative of an exit price in the Company’s principal market. In addition, the Company uses an internally developed model to perform testing on the valuations received from brokers. The Company has also considered both its own credit risk and counterparty credit risk in determining fair value and determined these adjustments were insignificant at March 31, 2021 and December 31, 2020.
The estimated fair value of the contingent consideration obligation of $13.5 million relating to the PendoTECH acquisition was determined using a Monte Carlo simulation based on the Company's forecast of future financial results. The fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement.
Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement consists of observable and unobservable inputs that reflect the assumptions that a market participant would use in pricing an asset or liability.
A fair value hierarchy has been established that categorizes these inputs into three levels:
Level 1: Quoted prices in active markets for identical assets and liabilities
Level 2: Observable inputs other than quoted prices in active markets for identical assets and liabilities
Level 3: Unobservable inputs
The following table presents the Company’s assets and liabilities, which are all categorized as Level 2 and are measured at fair value on a recurring basis at March 31, 2021 and December 31, 2020. The Company does not have any assets or liabil ities which are categorized as Level 1 or Level 3, with the exception of the PendoTECH contingent consideration described above.

Total derivative liabilities |  | $ | 12,427 |  |  | $ | 23,291 |  |  |

The Company had $18.0 million and $14.3 million of cash equivalents at March 31, 2021 and December 31, 2020, respectively, the fair value of which is determined using Level 2 inputs, through quoted and corroborated prices in active markets. The fair value of cash equivalents approximates cost.
The fair value of the Company's debt exceeds the carrying value by approximately $39.6 million as of March 31, 2021. The fair value of the Company's fixed interest rate debt was estimated using Level 2 inputs, primarily utilizing discounted cash flow models based on estimated current rates offered for similar debt under current market conditions for the Company.

7. INCOME TAXES
The Company's reported tax rate was 19.3% and 17.2% during the three months ended March 31, 2021 and 2020, respectively. The provision for taxes is based upon using the Company's projected annual effective tax rate of 19.5% and 21.5% before non-recurring discrete tax items during 2021 and 2020, respectively. The difference between the Company's projected annual effective tax rate and the reported tax rate is related to the timing of excess tax benefits associated with stock option exercises.
8. DEBT
Debt consisted of the following at March 31, 2021:

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the Unaudited Interim Consolidated Financial Statements included herein.
General
Our interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021.
Changes in local currencies exclude the effect of currency exchange rate fluctuations. Local currency amounts are determined by translating current and previous year consolidated financial information at an index utilizing historical currency exchange rates. We believe local currency information provides a helpful assessment of business performance and a useful measure of results between periods. We do not, nor do we suggest that investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. We present non-GAAP financial measures in reporting our financial results to provide investors with an additional analytical tool to evaluate our operating results.
We also include in the discussion below disclosures of immaterial qualitative factors that are not quantified. Although the impact of such factors is not considered material, we believe these disclosures can be useful in evaluating our operating results.
COVID-19
The ongoing coronavirus pandemic ("COVID-19") pandemic has resulted in millions of confirmed cases throughout the world and in all countries where we conduct business. The outbreak has caused many governments to implement stay-at-home orders, quarantines, and significant restrictions on travel. Several governments have also implemented work restrictions that prohibit many employees from going to their customary work locations and that require these employees to work remotely if possible. These restrictions continue to change as COVID-19 evolves in each country and region.
The health and safety of our employees and business partners have been our highest priority throughout the COVID-19 pandemic, and we have implemented several preventative and protective measures. We have also continued to support our customers with their essential businesses such as life sciences, food manufacturing, chemicals (e.g., sanitizers, disinfectants, soaps, etc.), food retail, and transportation and logistics. Our production and logistics facilities are currently operational, and our office-based employees have been able to work remotely in adherence to applicable jurisdictional stay-at-home orders. Our supply chain is currently continuing with minimal interruption, and we generally maintain adequate product inventory levels and safety stock for certain components. We continue to leverage our digital and remote sales and service capabilities, while also meeting delivery requirements with our global supply chain. Our service organization also continues to provide on-site and remote customer support to facilitate uptime, productivity, and regulatory compliance.
COVID-19 presents several risks to our business as further described in Part I, Item 1A of our Annual Report on Form 10-K for the yea r ended December 31, 2020. Uncertainties related to COVID-19 and the resulting impact to the global economy continue in most regions of the world and market conditions can change quickly. The longer-term effects on our business will be impacted by the global economy and any recession implications in different regions of the world.

Our reported tax rate was 19.3% and 17.2% during the three months ended March 31, 2021 and 2020, respectively. The provision for taxes is based upon using our projected annual effective tax rate of 19.5% and 21.5% before non-recurring discrete tax items for the three months ended March 31, 2021 and 2020, respectively. The difference between our projected annual effective tax rate and the reported tax rate is related to the timing of excess tax benefits associated with stock option exercises.

Total net sales and net sales to external customers both increased 19% in U.S. dollars and 14% in local currencies during the three month period ended March 31, 2021 compared to the corresponding period in 2020. The increase in net sales to external customers includes strong growth in most product categories.
Segment profit increased $9.1 million for the three months ended March 31, 2021 compared to the corresponding period in 2020. The increase in segment profit is primarily related to increased sales volume and favorable foreign currency translation.
Liquidity and Capital Resources
Liquidity is our ability to generate sufficient cash flows from operating activities to meet our obligations and commitments. In addition, liquidity includes available borrowings under our Credit Agreement, the ability to obtain appropriate financing and our cash and cash equivalent balances. Currently, our liquidity needs are primarily driven by working capital requirements, capital expenditures, share repurchases and acquisitions.
Cash provided by operating activities totaled $158.9 million during the three months ended March 31, 2021, compared to $65.5 million in the corresponding period in 2020. The increase in 2021 is primarily due to higher net earnings as well as favorable working capital and the timing of tax payments.
Capital expenditures are made primarily for investments in information systems an d technology, machinery, equipment and the purchase and expansion of facilities. Our capital expenditures totaled $24.6 million for the three months ended March 31, 2021 compared to $18.8 million in the corresponding period in 2020. We expect to make net investments in new or expanded manufacturing facilities of $10 million to $15 million in 20 21.

As of March 31, 2021, approximately $460.7 million of additional borrowings was available under our Credit Agreement, and we maintained $106.7 million of cash and cash equivalents. During the three months ended March 31, 2021, the Company increased its long-term debt primarily due to the funding of the PendoTECH acquisition as described in Note 4. Changes in exchange rates between the currencies in which we generate cash flows and the currencies in which our borrowings are denominated affect our liquidity. In addition, because we borrow in a variety of currencies, our debt balances fluctuate due to changes in exchange rates. Further, we do not have any downgrade triggers relating to ratings from rating agencies that would accelerate the maturity dates of our debt.
We currently believe that cash flow from operating activities, together with liquidity available under our Credit Agreement and local working capital facilities and our cash balances, will be sufficient to fund currently anticipated working capital needs and capital spending requirements for the foreseeable future.
In December 2020, the Company entered into an agreement to issue and sell EUR 125.0 million of 15-year 1.06% Euro Senior Notes ("1.06% Euro Senior Notes"). The terms of the Euro Senio r Notes are consistent with the previous Euro Senior Notes as described in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. The Company also entered into a forward contract to receive $152.1 million at the time of issuing the 1.06% Euro Senior Notes in March 2021. The Company issued the 1.06% Euro Senior Notes with a fixed interest rate of 1.06% in March 2021. The 1.06% Euro Senior Notes are unsecured obligations of the Company and will mature on March 19, 2036. Interest on the 1.06% Euro Senior Notes is payable semi-annually in March and September of each year.
In 2018, two of the Company's non-U.S. pension plans issued loans totaling $39.6 million (Swiss franc 38 million) to a wholly owned subsidiary of the Company. The loans have the same terms and conditions which include an interest rate of Swiss franc LIBOR plus 87.5 basis points. The loans were renewed for one year in April 2021.

We continue to explore potential acquisitions. In connection with any acquisition, we may incur additional indebtedness. In March 2021, we acquired all the membership interests of Mayfair Technology, LLC, ("PendoTECH") a manufacturer and distributor of single-use sensors, transmitters, control systems and software for measuring, monitoring and data collection primarily in bioprocess applications. PendoTECH serves bio-pharmaceutical manufacturers and life science laboratories and is located in the United States. The initial cash payment was $185.0 million and we may be required to pay additional consideration of up to $20.0 million and other post-closing amounts. For additional information related to the PendoTECH acquisition refer to Note 4 to the interim consolidated financial statements.
Share Repurchase Program
In November 2020, the Company's Board of Directors authorized an additional $2.5 billion to the share repurchase program which has $2.8 billion of remaining availability as of March 31, 2021. The share repurchases are expected to be funded from cash generated from operating activities, borrowings, and cash balances. Repurchases will be made through open market transactions, and the amount and timing of purchases will depend on business and market conditions, the stock price, trading restrictions, the level of acquisition activity, and other factors.
We have purchased 29.7 million common shares since the inception of the program in 2004 through March 31, 2021. During the three months ended March 31, 2021 and 2020, we spent $262.5 million and $200.0 million on the repurchase of 224,808 shares and 268,161 shares at an average price per share of $1,167.64 and $745.80, respectively. We reissued 22,388 shares and 50,372 shares held in treasury for the exercise of stock options and restricted stock units during the three months ended March 31, 2021 and 2020, respectively.
Effect of Currency on Results of Operations
Our earnings are affected by changing exchange rates. We are most sensitive to changes in the exchange rates between the Swiss franc, euro, Chinese renminbi, and U.S. dollar. We have more Swiss franc expenses than we do Swiss franc sales because we develop and manufacture products in Switzerland that we sell globally, and have a number of corporate functions located in Switzerland. When the Swiss franc strengthens against our other trading currencies, particularly the U.S. dollar and euro, our earnings decrease. We also have significantly more sales in the euro than we do expenses. When the euro weakens against the U.S. dollar and Swiss franc, our earnings also decrease. We estimate a 1% strengthening of the Swiss franc against the euro would reduce our earnings before tax by approximately $1.6 million to $1.8 million annually.
We also conduct business in many geographies throughout the world, including Asia Pacific, the United Kingdom, Eastern Europe, Latin America, and Canada. Fluctuations in these currency exchange rates against the U.S. dollar can also affect our operating results. The most significant of these currency exposures is the Chinese renminbi. The impact on our earnings before tax of the Chinese renminbi weakening 1% against the U.S. dollar is a reduction of approximately $2.3 million to $2.5 million annually.
In addition to the effects of exchange rate movements on operating profits, our debt levels can fluctuate due to changes in exchange rates, particularly between the U.S. dollar, the Swiss franc, and euro. Based on our outstanding debt at March 31, 2021, we estimate that a 5% weakening of the U.S. dollar against the currencies in which our debt is denominated would result in an increase of approximately $33.3 million in the reported U.S. dollar value of our debt.
