Effective tax rate from continuing operations(24.9)%18.4 %(11.2)%13.7 %

The change in our reported tax rates for the second quarter and first six months of 2021, as compared to the same periods in 2020, relates primarily to the impact of certain receipts and charges that are taxed at different rates than our effective tax rate. These receipts and charges include acquisition/divestiture-related net charges (credits), restructuring and restructuring-related net charges (credit), litigation charges, investment portfolio net losses (gains), as well as certain discrete tax items primarily related to changes in foreign tax rates, and changes in tax laws adopted in the second quarter of 2021, as well as the impacts of the Coronavirus Aid, Relief and Economic Security (CARES) Act in the second quarter of 2020.

As of June 30, 2021, we had $280 million of gross unrecognized tax benefits, of which a net $195 million, if recognized, would affect our effective tax rate. As of December 31, 2020, we had $261 million of gross unrecognized tax benefits, of which a net $183 million, if recognized, would affect our effective tax rate. The change in our gross unrecognized tax benefit is primarily related to positions on new entities we acquired through recent acquisitions and restructuring activities.

It is reasonably possible that within the next 12 months, we will resolve multiple issues with foreign, federal and state taxing authorities, resulting in a reduction in our balance of unrecognized tax benefits of up to $24 million.
Economic stimulus legislation has been enacted in many countries in response to the COVID-19 pandemic. In the U.S., the CARES Act, enacted on March 27, 2020, provided an estimated $2.2 trillion in COVID-19 pandemic-related relief, and included tax relief and government loans, subsidies and other relief for entities in affected industries. While we have not applied for government loans, we have taken advantage of the benefits offered in multiple jurisdictions, including the U.S. provision allowing taxpayers to defer payment of the employer portion of certain payroll taxes incurred in 2020. This allowed us to preserve cash generated from operations to service our debt obligations and other near-term commitments and is expected to be paid in full by the end of 2022 as permitted by the legislation.
