Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The most significant of these estimates include: (i) the underlying cash flows and holding periods used in assessing impairment; (ii) the determination of useful lives for tangible and intangible assets; and (iii) the assessment of the collectability of receivables, including deferred rent receivables. In March 2020, the World Health Organization declared a global pandemic related to the novel coronavirus ("COVID- 19"). The significance, extent and duration of the impact of COVID-19 on us and our tenants remains largely uncertain and dependent on near-term and future developments that cannot be accurately predicted at this time, such as the continued severity, duration, transmission rate and geographic spread of COVID-19, the roll-out, effectiveness and willingness of people to take COVID-19 vaccines, the extent and effectiveness of the containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in the area in which we operate. The ultimate adverse impact of COVID-19 is highly uncertain; however, the effects of COVID-19 on us and our tenants have affected estimates used in the preparation of the underlying cash flows used in assessing our long-lived assets for impairment and the assessment of the collectability of receivables from tenants, including deferred rent receivables. We have made what we believe to be appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent these estimates differ from actual results, our consolidated financial statements may be materially affected. Due to the business disruptions and challenges caused by COVID-19, we have provided rent deferrals and other lease concessions to certain tenants. We have entered into agreements with certain tenants, many of which have been placed on the cash basis of accounting, resulting in the deferral to future periods or abatement of $1.9 million of rent that had been contractually due in the first quarter of 2021. We are in the process of negotiating additional rent deferrals and other lease concessions with some of our tenants, which have been considered when establishing credit losses against billed and deferred rent receivables. During 2020, we put substantially all co-working tenants and retailers except for grocers, pharmacies, essential businesses and certain national credit tenants on the cash basis of accounting. Recent Accounting Pronouncements Reference Rate Reform In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2020-04, Reference Rate Reform ("Topic 848"). Topic 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in Topic 848 is optional and may be elected over the period March 12, 2020 through December 31, 2022 as reference rate reform activities occur. During the three months ended March 31, 2021, no elections were made. During the year ended December 31, 2020, we elected to apply the hedge accounting expedients related to (i) the assertion that our hedged forecasted transactions remain probable and (ii) the assessments of effectiveness for future London Interbank Offered Rate ("LIBOR") indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves our past presentation of our derivatives. We will continue to evaluate the impact of the guidance and may apply other elections, as applicable.
