HY Proxy FP announcement 

Subject: Shareholders asked to vote their proxy
Dear NAME:
I wanted to inform you that a proxy will mail to Principal Funds shareholders on February 1, asking for
approval of a number of proposals:
·	The election of 14 Directors as members of the Board of Directors.
·	Amended and Restated Articles of Incorporation.
·	Amended fundamental investment restrictions relating to: senior securities, commodities, real
	estate, borrowing, making loans, diversification, concentration, and underwriting securities.
·	The elimination of fundamental investment restrictions relating to short sales of securities.
One additional proposal specifically affects the Principal High Yield Fund. It asks shareholders to
approve a Sub-Advisory Agreement that will allow the current portfolio managers to perform their
services on behalf of Principal Global Investors rather than Edge Asset Management. Essentially, this
is an internal re-assignment of the personnel of affiliated sub-advisors. There won’t be substantive
change in either the nature or quality of their services or in the management fees the Fund pays for
services.
Shareholders may receive calls soliciting their vote if they haven’t exercised their proxy.
If you’re interested you can view the full proxy statement here.
Thanks for your support of Principal Funds. Don't hesitate to contact me with any questions you may
have. I look forward to talking to you soon.
Best regards,
