The following tables present ALLL and AULC activity by portfolio segment for the three-month periods ended March 31, 2021 and 2020.
(1)Relates to day one impact of the CECL adjustment as a result of the implementation of ASU 2016-13.
At March 31, 2021, the ACL was $1.7 billion, a decrease of $125 million from the December 31, 2020 balance of $1.9 billion. The decrease was primarily related to a reduction in credit reserves reflecting an improvement in the economic outlook. NCOs decreased $48 million, or 43%, in for the three-month period ended March 31, 2021. The decrease was driven by both commercial and consumer NCOs.The suite of CECL models are generally dependent on the rate of change in unemployment rather than the absolute unemployment levels. Additionally, the economic scenarios used in the March 31, 2021 ACL determination contained significant judgmental assumptions around the ultimate number of COVID-19 cases and the economic impact of additional stimulus spending enacted into law during the first quarter. Given the impact of the unemployment variable utilized within the models and the uncertainty associated with key economic scenario assumptions, the March 31, 2021 ACL included a material general reserve component as well as additional industry specific risk profiles to capture economic uncertainty not addressed within the quantitative transaction reserve.
