MassMutual executive vice president and CFO Michael Rollings said that the company’s economy and its industry were tested in 2011 by volatile market conditions, a sluggish economy, and continued low interest rates.

"While these conditions presented challenges, the strong operating fundamentals of our core businesses and our financial strength allowed us to remain focused on providing high dividends, trusted financial guidance and excellent service to our policyholders," Rollings said.
