Exhibit 99.3

Report of Independent Registered Public Accounting Firm on Compliance

The Board of Directors
Principal Financial Group, Inc.
Principal Life Insurance Company

We have examined management’s assertion, included in the accompanying report titled Report of Management on Compliance, that Principal Financial Group, Inc. and Principal Life Insurance Company (collectively, the “Company”) complied with the specified standards identified in Exhibit A to the Report of Management on Compliance (the “specified standards”) with respect to the secured notes issued by Principal Life Income Fundings Trust 2004-59 during the year ended December 31, 2004. Management is responsible for the Company’s compliance with those specified standards. Our responsibility is to express an opinion on management’s assertion about the Company’s compliance based on our examination.

Our examination was conducted in accordance with attestation standards established by the Public Company Accounting Oversight Board (United States) and, accordingly, included examining, on a test basis, evidence about the Company’s compliance with the specified standards and performing such other procedures as we considered necessary in the circumstances. We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on the Company’s compliance with the specified standards.

In our opinion, management’s assertion that Principal Financial Group, Inc. and Principal Life Insurance Company complied with the aforementioned specified standards during the year ended December 31, 2004, is fairly stated, in all material respects.
