Twitter will pay more than $800 million to settle a consolidated class-action securities lawsuit alleging the social-media company deliberately misled investors about user engagement in 2015.

Frontier filed for bankruptcy to implement a prearranged $10 billion debt-cutting proposal backed by the telephone and internet-service provider’s bondholders. The telecommunications company is the country’s No. 7 broadband provider by subscribers and the No. 4 incumbent telephone company after AT&T, CenturyLink and Verizon Communications, a legacy of the 1984 breakup of the Ma Bell monopoly. Frontier grew quickly over the past two decades by scooping up phone networks that other companies were eager to unload.
