Citigroup Inc. earned less from running a bank in Japan than its global chief executive officer's salary last year, helping explain why the U.S. lender is considering selling the consumer business as Abenomics crushes loan returns. Citibank Japan Ltd.'s net income of 1.34 billion yen ($12.9 million) in the year ended March compared with CEO Michael Corbat's total 2013 compensation of $14.5 million. The U.S. bank has begun approaching Japanese companies including the three biggest lenders, trust banks and regional lenders, a person familiar with the matter said this week.
