Bryant and Jon Gober The year-end fair market value of all Individual Retirement Arrangements (IRAs) rose from $3.7 trillion in 2008 to $4.5 trillion in 2009 to $5.0 trillion in 2010. Roth IRA conversions increased significantly in 2010, rising over 800 percent, to $64.8 billion and surpassing contributions for the first time. This growth was primarily due to new tax provisions that expanded the availability of Roth conversions to all income levels. However, Roth conversions were not responsible for the changes in the year-end fair market values. This nearly 37-percent increase was the result of improvements in the value of investments.
