Corbat earned an estimated $16.5 million in 2015, including deferred shares worth about $4.5 million. He earned $13 million in 2014.
Deferred stock makes up about 30 percent of Corbat's bonus pay under Citi's executive compensation plan, which was overhauled three years ago amid shareholder pressure.

Morgan Stanley cut Chief Executive James Gorman's overall pay by 7 percent to $21 million in 2015, while Goldman Sachs counterpart Lloyd Blankfein's pay declined 4 percent to $23 million.
The payout for Corbat and a few other executives can be estimated from regulatory filings made by the banks, and a pay formula that Citigroup has previously disclosed.
