"The transfer of some bank deposits is the next important step in Principal Bank's transformation to a limited purpose trust institution. After the transfer, Principal Bank will continue to provide services to support the Principal Financial Group retirement business," said Barrie Christman, president, chairman and CEO of Principal Bank. "Principal Bank currently has deposits of $1.9 billion associated with the retirement businesses, including all individual retirement accounts (IRAs)."

BofI Federal Bank CEO, Gregory Garrabrants stated, "We look forward to providing an outstanding product and great customer service to Principal Bank's customers. We are delighted to be chosen by Principal Bank and we will work hard to earn the business of our new customers."

The business transaction is expected to be seamless for clients and advisors of The Principal. Christman notes, "We chose BofI Federal Bank because their business model, fees and products are very similar to those of Principal Bank. We encourage our customers to take advantage of the products and services available through BofI."

This transaction is subject to approval by the Office of the Comptroller of the Currency.
