massive data breach incurred by Marriott in November 2018 has cost the world’s
biggest hotel chain only a scant $3 million so far, after the company’s insurer
covered most of the costs associated with the hack.

the 2018 fourth quarter, the company incurred $28 million of expenses and
recognized $25 million of insurance proceeds related to the data security
incident it disclosed on November 30, 2018. 
The $3 million of net expenses are reflected in either the Reimbursed
expenses or Merger-related costs and charges lines of the Statements of Income,
which have been excluded from adjusted net income, adjusted EPS and adjusted

Arne M. Sorenson said the integration of Starwood (whose very acquisition was

conduct sophisticated hacks while remaining undiscovered for long periods of
