SUBSEQUENT EVENTS	SUBSEQUENT EVENTSOn July 28, 2020, the Board approved the declaration of a quarterly dividend of $0.56 per share of Moody’s common stock, payable on September 10, 2020 to shareholders of record at the close of business on August 20, 2020.On July 29, 2020, the chief executive officer of Moody’s approved a restructuring program primarily in response to the COVID-19 pandemic which revolves around the rationalization and exit of certain real estate leases. The exit from certain leased office space is anticipated to begin in the third quarter of 2020 and be substantially completed during the first half of 2021, and is expected to result in an estimated annualized savings of approximately $5 million to $6 million a year. The Program is estimated to result in total pre-tax charges of $25 to $35 million, which primarily reflects a non-cash charge related to operating lease right-of-use assets. Approximately $20 to $30 million of this amount is expected to be recorded in the second half of 2020.
