Significant estimates and assumptions made by management involve the fair value of goodwill and intangible assets acquired from business acquisitions, contingent consideration for a business acquisition and periodic reassessment of its fair value, valuation of investment in privately held companies classified under Level 3 fair value hierarchy, pension obligations, accruals for customer incentives, cooperative marketing, and pricing programs and related breakage when appropriate, inventory valuation, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets.

Risks and Uncertainties	Risks and Uncertainties Impacts of Macroeconomic and Geopolitical Conditions and Other Factors on the Company's Business In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which continues to spread throughout the world. The COVID-19 pandemic resulted in industry-wide global supply chain challenges, including manufacturing, transportation and logistics. The Company purchases certain products and key components from a limited number of sources, and depends on the supply chain, including freight, to receive components, transport finished goods and deliver the Company's products across the world. More recently, the Company has also been impacted by adverse macroeconomic and geopolitical conditions. These conditions include but are not limited to inflation, foreign currency fluctuations, and slowdown of economic activity around the world, in part due to rising interest rates, and lower consumer and enterprise spending. In addition, the war in Ukraine increased global supply chain, logistics, and inflationary challenges. Such global or regional economic and political conditions adversely affect demand for the Company's products. These conditions also have an impact on the Company's suppliers, contract manufacturers, logistics providers, and distributors, causing volatility in cost of materials and shipping and transportation rates, and as a result impacting the pricing of the Company's products. Price increases may not successfully offset cost increases or may cause the Company to lose market share and in turn adversely impact the Company's results of operations. While global supply chain challenges have improved since the second quarter of fiscal year 2023, including logistics costs and shipping lead times, the increase of COVID-19 infections in China during the third quarter of fiscal year 2023 causes uncertainty in supply availability. If macroeconomic and geopolitical conditions and COVID-19 related factors do not improve or worsen, the Company's results of operations will continue to be adversely impacted.

Recent Accounting Pronouncements Adopted

In October 2021, the Financial Accounting Standard Board issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" (ASU 2021-08). The update requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers, as if it had originated the contracts. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company early adopted the standard effective April 1, 2022 and applies the standard prospectively to business combinations that occurred on or after April 1, 2022. The adoption of ASU 2021-08 did not have a material impact on the Company's condensed consolidated financial statements.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill and intangible assets acquired from business acquisitions, contingent consideration for a business acquisition and periodic reassessment of its fair value, valuation of investment in privately held companies classified under Level 3 fair value hierarchy, pension obligations, accruals for customer incentives, cooperative marketing, and pricing programs and related breakage when appropriate, inventory valuation, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these

estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates.
