On an ongoing basis we evaluate our estimates, judgments and assumptions. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities and equity and the amount of revenue and expense. Actual results may differ from these estimates.</span></div><div style="margin-top:9pt"><span style="color:#2573ba;font-family:'Franklin Gothic Book',sans-serif;font-size:11pt;font-weight:700;line-height:120%">Significant Accounting Policies</span></div><span style="color:#000000;font-family:'Franklin Gothic Book',sans-serif;font-size:10pt;font-weight:400;line-height:120%">There have been no material changes to our significant accounting policies disclosed in </span><span style="color:#000000;font-family:'Franklin Gothic Book',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Note 1, Summary of Significant Accounting Policies</span><span style="color:#000000;font-family:'Franklin Gothic Book',sans-serif;font-size:10pt;font-weight:400;line-height:120%">, to our audited consolidated financial statements included in our 2023 Form 10-K.</span> | ||
