Due to the 3%annual rate increase limitation a portion of a 2019 surcharge may not be fully recovered by 12/31/2022 and therefore would not be recognizable as income for financial reporting purposes in 2020.The income statement impact of any contra deferral entries will be eliminated for for each quarter of 2020.The similarity of the percentage change indicates that the mechanism is working as intended.
