Operator
Ladies and gentlemen, thank you for standing by and welcome to the Brandywine Realty Trust First Quarter 2021 Earnings Call. [Operator Instructions] I would now like to hand the conference over to your speaker today, Jerry Sweeney, President and CEO. Please go ahead. Sara, thank you very much. Good morning everyone and thank you for participating in our first quarter 2021 Earnings Call. As per our normal process, on today's call with me are George Johnstone, our Executive Vice President of Operations. Dan Palazzo, Our Vice President and Chief Accounting Officer. Tom Wirth, our Executive Vice President and Chief Financial Officer. Prior to beginning, certain information discussed during our call may constitute forward-looking statements within the meaning of the federal securities law. Although we believe estimates reflected in these statements are based on reasonable assumptions, we cannot give assurance that the anticipated results will be achieved. For further information on factors that could impact our anticipated results please reference to our press release, as well as our most recent annual and quarterly reports that we filed with the SEC. First and foremost, we hope that everyone is -- continues to be safe, healthy, engaged and looking forward to return to some semblance of normalcy. The pandemic continues to disrupt, but with the vaccine deployment being accelerated, we are on a path toward that normalcy. There is more optimism about the economy opening up and we are hearing that directly from many of our 1200 tenants. Our portfolio right now still only remains about 15% to 20% occupied and the predominance of tenants of return thus far are the small and medium size employers. What's interesting though is many restrictions imposed by governmental agencies are being gradually loosened by state and local governments. That happened just recently here in Pennsylvania and Philadelphia, and we believe that those changes will definitely accelerate the return to the workplace.
