Balaji Krishnamurthy --
Investor Relations
Thank you, David. Thank you for joining us today, and welcome to Uber Technologies' fourth-quarter and full-year 2020 earnings presentation. On the call today, we have Uber's CEO, Dara Khosrowshahi; and CFO, Nelson Chai. This is Balaji Krishnamurthy from the Investor Relations team.
During today's call, we will present both GAAP and non-GAAP financial measures. Additional disclosures regarding these non-GAAP measures, including a reconciliation of GAAP to non-GAAP measures, are included in the press release, supplemental slides, and our filings with the SEC, each of which is posted to investor.uber.com. I will remind you that these numbers are unaudited and may be subject to change. Certain statements in this presentation and on this call are forward-looking statements.
