(1) The commercial coverage ratio includes a 21 basis point reduction associated with PPP loans as of December 31, 2020. The difference in ACL as of December 31, 2020 as compared to December 31, 2019 continues to be driven by the COVID-19 pandemic, associated lockdowns and the resulting economic impacts from March to December 31, 2020, as well as the Company’s adoption of CECL on January 1, 2020. Citizens added $451 million in ACL upon adoption of CECL, and has since added an additional $923 million in the year ended December 31, 2020, resulting in an ending ACL balance of $2.7 billion. The increase in commercial net charge-offs in the year ended December 31, 2020 compared to the year ended December 31, 2019 was driven by charge-offs in the retail real estate, metals and mining, energy and related, and casual dining industry sectors. Retail net charge-offs in the year ended December 31, 2020 reflected the benefit of forbearance and stimulus activity stemming from the COVID-19 pandemic and associated lockdowns. To determine the ACL as of December 31, 2020, we utilized an economic scenario that generally reflects real GDP growth of approximately 4% over 2021, returning to fourth quarter 2019 real GDP levels by the last quarter of 2021. The scenario also projects the unemployment rate to be in the range of approximately 7% to 7.5% throughout 2021. While the macroeconomic forecast was slightly improved relative to the third quarter 2020 forecast, we continued to apply management judgment to adjust the modeled reserves in the commercial industry sectors most impacted by the COVID-19 pandemic and associated lockdowns, including retail and hospitality, casual dining, retail trade, price-sensitive energy and related, and educational services, as well as in certain retail products. The following tables present a summary of changes in the ACL for the year ended December 31, 2019 and 2018:

(1) Includes PPP loans designated as pass that are fully guaranteed by the SBA originating in 2020. For retail loans, Citizens utilizes credit scores provided by FICO and the loan’s payment and delinquency status to monitor credit quality. Management believes FICO credit scores are considered the strongest indicator of credit losses over the contractual life of the loan as the scores are based on current and historical national industry-wide consumer level credit performance data, and assist management in predicting the borrower’s future payment performance. The following table presents the amortized cost basis of retail loans, by vintage date and FICO scores that are generally refreshed quarterly, as of December 31, 2020:
