	Registration Statement on Form N-14 (File No. 333-164920)
Ladies and Gentlemen:
Pursuant to Rule 461 under the Securities Act of 1933, as amended, Principal Funds, Inc. (the
“Registrant”) and its principal underwriter, Principal Funds Distributor, Inc., hereby request that the
effectiveness of the above-referenced Registration Statement on Form N-14 be accelerated to March 18,
2010, or as soon thereafter as practicable.
In connection with the foregoing request for acceleration, the Registrant hereby acknowledges that:
·	should the Securities and Exchange Commission (the “Commission”) or the staff, acting pursuant
	to delegated authority, declare the filing effective, it does not foreclose the Commission from
	taking any action with respect to the filing;
·	the action of the Commission or staff, acting pursuant to delegated authority, in declaring the
	filing effective, does not relieve the Registrant from its full responsibility for the adequacy and
	accuracy of the disclosure in the filing; and
·	the Registrant may not assert staff comments and the declaration of effectiveness as a defense in
	any proceeding initiated by the Commission or any person under the federal securities laws of the
	United States.
If you have any questions regarding this request, please contact, and upon the acceleration of
effectiveness of the Registration Statement, please notify Adam U. Shaikh at 515-235-9328.
Very truly yours,
