CY2023	us-gaap	Use Of Estimates UseOfEstimates	The preparation of the consolidated financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures of contingent assets and liabilities. Though macroeconomic factors such as inflation, exchange rate fluctuations and concerns about an economic downturn present additional uncertainty, we continue to use the best information available to inform our critical accounting estimates. Actual results could differ from those estimates.

Significant technological changes, shifting customer needs, the emergence of competitive products or services with new capabilities, and other factors could negatively impact our operating results. A portion of our customers consist of university and research institutions that management believes are, to some degree, directly or indirectly supported by the United States Government. A significant change in current research funding, particularly with respect to the U.S. National Institutes of Health, could have an adverse impact on future revenues and results of operations. </span></div><div style="padding-left:13.5pt"><span><br/></span></div><div style="padding-left:13.5pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">International sales entail a variety of risks, including currency exchange fluctuations, longer payment cycles, and greater difficulty in accounts receivable collection. We are also subject to general geopolitical risks, such as political, social and economic instability, and changes in diplomatic and trade relations. The risks of international sales are mitigated in part by the extent to which sales are geographically distributed. Shipments to customers outside the United States comprised 48%, 50%, and 52% of total revenue in 2023, 2022, and 2021, respectively. Customers outside the United States represented 55% and 54% of our gross trade accounts receivable balance as of December 31, 2023 and January 1, 2023, respectively. </span></div><div style="padding-left:13.5pt"><span><br/></span></div><div style="padding-left:13.5pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We had no customers that provided more than 10% of total revenue in 2023, 2022, and 2021.

Most of our cash and cash equivalents as of December 31, 2023 were deposited with U.S. financial institutions, either domestically or with their foreign branches. Our investment policy restricts the amount of credit exposure to any one issuer to 5% of the portfolio or 5% of the total issue size outstanding at the time of purchase and to any one industry sector, as defined by Clearwater Analytics (Industry Sector Report), to 30% of the portfolio at the time of purchase. There is no limit to the percentage of the portfolio that may be maintained in debt securities, U.S. government-sponsored entities, U.S. Treasury securities, and money market funds.
