Explanatory Note

This amendment to Principal Financial Group, Inc.’s proxy statement is filed to correct

administrative errors contained in the proxy statement filed with the Securities and Exchange Commission on April 7, 2014. Both errors appear on page 40, which discusses determination of annual incentive compensation for named executive officers.

The first minor error appears in the text in the first “2013 Assessment” box. At the end of the second sentence, the target for earnings per diluted share should have been $3.38 instead of $3.34.

The second administrative error appears in the fourth “2013 Assessment” box. The result of Specialty Benefits premium and fees should have been $1,492.7 million and not $1,492.7 billion.
