Significant Accounting Policies Update	2. SIGNIFICANT ACCOUNTING POLICIES UPDATE Our significant accounting policies are detailed in "Note 2, Summary of Significant Accounting Policies" of our 2021 Annual Report. Additionally, we updated the following accounting policy during the three and six months ended June 30, 2022: Property, Plant and Equipment We review our long-lived assets ("LLA") for impairment when events or changes in circumstances indicate that their net book value may not be recovered over their remaining service lives. Indicators of possible impairment may include significant declines in activity levels in regions where specific assets or groups of assets are located, extended periods of idle use, declining revenue or cash flow or overall changes in general market conditions. The geopolitical conflict between Russia and Ukraine, which began in February 2022 and has continued through June 30, 2022, has resulted in disruptions to our operations in Ukraine and Russia. The Company has assessed the need for impairment testing for LLA in Russia and Ukraine as of June 30, 2022. As of June 30, 2022, all laboratory facilities, offices, and locations in Russia continued to operate and remained profitable, which formed the basis of our projections for evaluating impairment, and no specific asset impairments were identified. With regard to the Company’s operations and associated fixed assets in Ukraine, there is no damage to our facilities as of June 30, 2022. However, since March 2022, our operations were temporarily suspended out of concern for the safety of our employees. During the three months ended June 30, 2022, the Company has performed limited operations in Ukraine as the circumstances permit, and intends to continue resuming operations in Ukraine at such time as we believe appropriate and safe for our local employees. Therefore, we determined there was no impairment for LLA in Ukraine as of June 30, 2022.
