d) Calculate the current ratio of PG&E in 2021

Consolidated Balance Sheets LIABILITIES AND EQUITY Current Liabilities Useful Footnotes: 1. Allowance for uncollectible accounts The table below presents the activity of the current and noncurrent loyalty program deferred revenue, and includes miles earned through travel and miles sold to participating companies, which are primarily through marketing agreements ("-" indicates zero.). 2. Property, Plant, and Equipment Property, plant, and equipment are reported at the lower of their historical cost less accumulated depreciation or fair value. Historical costs include labor and materials, construction overhead. The Utility's estimated service lives of its property, plant, and equipment were as follows: (1) Balance includes nuclear fuel inventories. Stored nuclear fuel inventory is stated at weighted-average cost. Nuclear fuel in the reactor is expensed as it is used based on the amount of energy output. See Note 15 below. The Utility depreciates property, plant, and equipment using the composite, or group, method of depreciation, in which a single depreciation rate is applied to the gross investment balance in a particular class of property, with the exception of its securitized property, plant and equipment, which is depreciated over the life of the bond and a pattern consistent with principal payments. This method approximates the straight-line method of depreciation over the useful lives of property, plant, and equipment. The Utility's composite depreciation rates were 3.82% in 2021,3.76% in 2020, and 3.80% in 2019 The following table summarizes PG\&E Corporation's and the Utility's long-term debt: Consolidated Balance Sheets LIABILITIES AND EQUITY Current Liabilities Useful Footnotes: 1.
