Basis of Presentation and Other Items	1. Basis of Presentation and Other Items. The interim consolidated financial statements of Merit Medical Systems, Inc. ("Merit," "we" or "us") for the three and nine-month periods ended September 30, 2020 and 2019 are not audited. Our consolidated financial statements are prepared in accordance with the requirements for unaudited interim periods and, consequently, do not include all disclosures required to be made in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of our management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of September 30, 2020 and December 31, 2019, and our results of operations and cash flows for the three and nine-month periods ended September 30, 2020 and 2019. The results of operations for the three and nine-month periods ended September 30, 2020 and 2019 are not necessarily indicative of the results for a full-year period. Within the financial statements and tables presented, certain columns and rows may not total due to the use of rounded numbers for disclosure purposes. Percentages and earnings per share amounts presented are calculated from the underlying amounts. These interim consolidated financial statements should be read in conjunction with the financial statements and risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2019 (as amended by an Amendment No. 1 to Annual Report on Form 10-K/A, the “Annual Report on Form 10-K”). Reclassifications Certain reclassifications have been made to the 2019 periods to conform to the 2020 presentation. In the consolidated statements of cash flows for the nine months ended September 30, 2020, the fair value adjustment to contingent consideration is presented as a reconciling item between net income (loss) and cash flows from operating activities. A corresponding reclassification of approximately $3.6 million has been made in the prior period for comparability, along with corresponding reclassifications to the change in certain operating assets and liabilities. COVID-19 Pandemic The global coronavirus (“COVID-19”) pandemic has created significant uncertainty in the global economy, has negatively impacted our business, results of operations and financial condition, and we anticipate that it may negatively impact our business, results of operations and financial condition for the foreseeable future. At present, it is not possible for us to predict the extent of this impact due to uncertainties regarding the duration of the pandemic, potential government mandates regarding elective or deferrable procedures, and patient behavior, among other factors. In response to the COVID-19 pandemic, we implemented certain cost reduction and operating efficiency initiatives, including decreased discretionary spending, delayed product launches, deferred capital spending and reduced the number of research and development projects, among other initiatives. In April 2020, due to the significant impact of the COVID-19 pandemic on our business, results of operations and financial condition, and uncertainty regarding the scope and duration of that impact, we reduced headcount, implemented targeted furloughs and temporarily reduced salaries for a number of groups, including all executive positions. A number of these temporary salary reductions were decreased or eliminated during the three months ended September 30, 2020. We also implemented processes to encourage the safety of our employees, including formal policies restricting travel, temperature screenings at most of our manufacturing locations, and mandatory telecommuting for certain positions. As the impact of the COVID-19 pandemic evolves, we will continue to assess that impact on our business and respond accordingly. Sustained adverse impacts to our business, our suppliers, and our customers may also affect our future valuation of certain assets and therefore may increase the likelihood of an impairment charge, write-off, or reserve associated with such assets, including goodwill, intangible assets, property and equipment, inventories, accounts receivable, tax assets, and other assets. Estimates may change as new events occur and additional information is obtained, and actual results will likely differ, and may differ materially, from our estimates under different assumptions, circumstances or conditions.
