Verizon announced plans to buy Yahoo's core internet business nearly a year ago, and that tale has come to an end: assets have been acquired for $4.48 billion and will be combined with AOL brands under a new subsidiary called Oath, headed by former AOL CEO Tim Armstrong. Marissa Mayer, who penned a goodbye letter to her employees, has also officially resigned from the company. They say that 2,000 jobs may be slashed as Yahoo and AOL integrate. Verizon has completed its $4.48 billion acquisition of Yahoo's core internet business and said Tuesday that Marissa Mayer is stepping down. The assets, which include Yahoo Finance, will be combined with AOL brands such as the Huffington Post under a new subsidiary called Oath. Tim Armstrong, former CEO of AOL, will head the subsidiary, which houses more than 50 media and technology brands. Mayer, Yahoo CEO since July 2012, is expected to receive a "golden parachute" payment that filings with the Securities and Exchange Commission say is worth more than $23 million.
