Use of Non-GAAP Financial Measures A non-GAAP financial measure is a numerical measure of our performance, financial position, or cash flows that includes adjustments from a comparable financial measure presented in accordance with U.S. GAAP. We use a number of non-GAAP financial measures that management believes are useful to investors because they illustrate the performance of our normal, ongoing operations which is important in understanding and evaluating our financial condition and results of operations. While such measures are also consistent with measures utilized by investors to evaluate performance, they are not a substitute for U.S. GAAP financial measures. Therefore, we have provided reconciliations of the non- GAAP financial measures to the most directly comparable U.S. GAAP financial measure as a handout accompanying this presentation. We adjust U.S. GAAP financial measures for items not directly related to ongoing operations. However, it is possible that these adjusting items could recur in the future. Management also uses non-GAAP financial measures for goal setting, to determine employee and senior management awards and compensation, and to evaluate performance on a basis comparable to that used by securities analysts. We also use a variety of other measures that we do not consider to be non-GAAP financial measures. These are operational measures and do not have U.S. GAAP counterparts. Assets under management is an example of an operational measure.

Recent Performance Financial Operating earnings for 2006 of $102.5 million (CAGR of 23% since 2001) Pre-tax profit margin of 32.2% has grown steadily over the last several years single most important metric for asset managers compares favorably with asset management peers Direct expenses (excluding acquisition related expenses) of 18bp of average assets under management is very much in line with peer companies Asset management tends to have very high scale benefits as assets and revenue can grow materially more rapidly than expenses This is true with respect to both investment professionals and operations area

Other Issues Actively search out growth opportunities through acquisition Tremendous success with our past acquisitions of Post, Spectrum, Columbus Circle and now Edge Add to range of product offerings including absolute return alternatives and international fixed income capabilities Highly successful transition of our mortgage securitization business to the joint venture with US Bank Significantly reduces risk to Principal Financial Group and provides more efficient use of corporate capital Transforms business into much more of a fee business while still allowing PrinREI to leverage its expertise in areas of origination, underwriting, warehousing, pooling and securitizing mortgage loans Relationship with USB expands our commercial real estate footprint throughout the country, resulting in more relationships and sourcing opportunities in both our debt and equity side of the fee operations
