(“Strategic Education” or the “Company”), a Maryland corporation, is an education services company that provides access to high-quality education through campus-based and online post-secondary education offerings, as well as through programs to develop job-ready skills for high-demand markets. Strategic Education’s portfolio of companies is dedicated to closing the skills gap by placing adults on the most direct path between learning and employment. As discussed in Note 2 and Note 3, the Company completed its acquisition of Torrens University and associated assets in Australia and New Zealand (“ANZ”) on November 3, 2020. </span></div><div style="margin-top:9pt;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As discussed in Note 20, beginning in the first quarter of 2021 the Company changed the way management reports financial information relied on by the Chief Operating Decision Maker (“CODM”) to evaluate performance and allocate the resources of the Company. The Company's revised organizational structure includes the following three operating and reportable segments: (1) U.S. Higher Education, which is primarily comprised of the Company's previous Strayer University and Capella University segments and is focused on providing flexible and affordable certificate and degree programs to working adults; (2) Education Technology Services, a new segment that is primarily focused on developing and maintaining relationships with employers to build employee education benefits programs; and (3) Australia/New Zealand, which provides certificate and degree programs in Australia and New Zealand. During the first three quarters of 2021, the Education Technology Services segment was called the Alternative Learning segment. The Australia/New Zealand segment was not changed as a result of the Company's reorganization. Prior period segment disclosures have been restated to conform to the current period presentation.</span></div>

The most significant management estimates include allowances for credit losses, useful lives of property and equipment and intangible assets, incremental borrowing rates, potential sublease income and vacancy periods, accrued expenses, forfeiture rates and the likelihood of achieving performance criteria for stock-based awards, value of free courses earned by students that will be redeemed in the future, valuation of goodwill and intangible assets, and the provision for income taxes. During the years ended December 31, 2020 and 2021, management estimates also include potential impacts the COVID-19 pandemic will have on student enrollment, tuition pricing, and collections of tuition receivables in future periods. The duration and severity of the COVID-19 pandemic and its impact on the Company’s consolidated financial statements is subject to uncertainty. Actual results could differ from those estimates.</span></div>
