Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsOn July 8, 2022, House Bill 1342 was signed into law in the Commonwealth of Pennsylvania, making significant changes to its corporate income tax rate. The bill reduces its corporate income tax rate from 9.99% to 4.99%, with reductions occurring in phases beginning each tax year from January 1, 2023 through January 1, 2031. GAAP requires companies to recognize the effect of tax law changes in the period of enactment. As a result, it is expected that there will be a decrease in “Deferred income taxes” on the Consolidated Balance Sheet and a corresponding decrease in “Income taxes” on the Income Statement in the third quarter of 2022. We currently estimate that the impact will be approximately $135 million.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
