"Improved equity market levels, solid underwriting results and our expense savings efforts also contributed to our strong performance in the quarter," MetLife Chairman President and CEO C Robert Henrikson said.
MetLife reported a net investment income which includes dividends and payments on bond rose 31 per cent from year-ago period to $4.3 billion in the first quarter ended March 31, 2010.
