Consumers concerned about outliving their retirement savings are increasingly buying deferred income annuities. Sales have risen for five quarters in a row. For this year's first quarter, sales of deferred income annuities were 150% above the figure for the same quarter a year ago. In 2012, sales rose to almost $1 billion. "As more companies begin to offer DIA products and as they expand into new distribution channels, DIAs are becoming a viable option for consumers and financial advisers looking for guaranteed retirement income to insure against longevity risk," said Cathy Weatherford, president and CEO of the IRI.
