The extent and duration of the impact of the COVID-19 pandemic on our operations and financial condition remain uncertain and difficult to predict. As a result of the COVID-19 pandemic, we believe that our patients are deferring visits to our O&P clinics, as well as elective surgical procedures, both of which impact our business volumes through decreased patient encounters and physician referrals.

The purpose of these funds is to reimburse providers for lost revenue and health-care related expenses that are attributable to the COVID-19 pandemic.

We recognized the benefit from the Grants within Other operating costs in our Patient Care segment. In April 2021, we recognized an additional $0.7 million in proceeds received from grants under the CARES Act. The CARES Act also provided for a deferral of the employer portion of payroll taxes incurred during the COVID-19 pandemic through December 2020. The provisions allowed us to defer half of such payroll taxes until December 2021 and the remaining half until December 2022.
