The most significant of these estimates include the underlying cash flows and holding periods used in assessing impairment, judgements regarding the recoverability of goodwill, and the assessment of the collectibility of receivables. Future impacts of the COVID-19 pandemic on Piedmont and its tenants may affect these and other estimates used in the preparation of these financial statements. While Piedmont has made, what it believes to be, appropriate accounting estimates based on the facts and circumstances available as of the reporting date, actual results could materially differ from those estimates.</span></div>
