Insurance Group was announced March 3, 2016. After Marriott raised its bid to $13.6billion on March 21, Starwood terminated the Anbang agreement and proceeded with the merger with Marriott. Following receipt of regulatory approvals, Marriott closed the merger with Starwood on September 23, 2016, creating the world's largest hotel company with over 5700 properties, 1.1million rooms, and a portfolio of 30 brands. The Starwood acquisition gave Marriott a larger non-US presence; approximately 75% of Starwood's revenues were from non-US markets. On November 30, 2018, Marriott disclosed that the former Starwood brands had been subject to a data breach. After the disclosure, Attorney General of New York Barbara Underwood announced an investigation into the data breach. The cyberattack was found to be a part of a Chinese intelligence-gathering effort that also hacked health insurers and the security clearance files of millions more Americans. The hackers are suspected of working on behalf of the Ministry of State Security, the country's Communist-controlled civilian spy agency. Initially, Marriott said that 500 million customers' personal information had been exposed. In January 2019, the company updated the number of guests affected to "less than 383 million" customers, and claimed many of the customer's payment cards had expired. In December 2019, the company acquired Elegant Hotels, operator of 7 hotels in Barbados. In February 2020, the company discovered a data breach that included the theft of contact information for 5.2 million customers. In April 2020, during the COVID-19 pandemic, the company instituted additional cleanliness standards, including requiring the use of electrostatic sprayers with disinfectant, adding disinfecting wipes in all hotel rooms, and removing or re-arranging furniture in public areas to allow more space for social distancing. During the pandemic, global occupancy fell as low as 31%. President and CEO Arne Sorenson died on February 15, 2021, from pancreatic cancer. On February 23, 2021, Anthony Capuano was appointed to fill Sorensen's vacancy as CEO and Director, having previously served as Marriott's group president of global development, design and operations. In November 2021, the company was criticized for refusing to host the World Uyghur Congress at one of its properties in Prague, citing reasons of "political neutrality". In August 2022, employees began moving into the company's new 21-story, 785,000-square-foot headquarters building on Wisconsin Avenue, ahead of an official opening on September 21. The new building was constructed over four years as part of a $600 million downtown Bethesda campus,
