The Principal Financial Group 101: May 2017

Principal Financial Group®

May 2017

A non-GAAP financial measure is a numerical measure of performance, financial position, or cash flows that includes adjustments from a comparable financial measure presented in accordance with U.S. GAAP. The company uses a number of non-GAAP financial measures that management believes are useful to investors because they illustrate the performance of the company’s normal, ongoing operations which is important in understanding and evaluating the company’s financial condition and results of operations. While such measures are also consistent with measures utilized by investors to evaluate performance, they are not, however, a substitute for U.S. GAAP financial measures. Therefore, on principal.com/investor, the company has provided reconciliations of the non-GAAP financial measures to the most directly comparable U.S. GAAP financial measure. The company adjusts U.S. GAAP financial measures for items not directly related to ongoing operations. However, it is possible these adjusting items have occurred in the past and could recur in future reporting periods. Management also uses non-GAAP financial measures for goal setting, as a basis for determining employee and senior management awards and compensation, and evaluating performance on a basis comparable to that used by investors and securities analysts. The company also uses a variety of other operational measures that do not have U.S. GAAP counterparts, and therefore do not fit the definition of non-GAAP financial measures. Assets under management is an example of an operational measure that is not considered a non-GAAP financial measure.

Certain statements made by the company which are not historical facts may be considered forward-looking statements, including, without limitation, statements as to operating earnings, net income available to common stockholders, net cash flows, realized and unrealized gains and losses, capital and liquidity positions, sales and earnings trends, and management’s beliefs, expectations, goals and opinions. The company does not undertake to update these statements, which are based on a number of assumptions concerning future conditions that may ultimately prove to be inaccurate. Future events and their effects on the company may not be those anticipated, and actual results may differ materially from the results anticipated in these forward-looking statements. The risks, uncertainties and factors that could cause or contribute to such material differences are discussed in the company’s annual report on Form 10-K for the year ended Dec. 31, 2016 , and in the company’s quarterly report on Form 10-Q for the quarter ended Mar. 31, 2017, filed by the company with the U.S. Securities and Exchange Commission, as updated or supplemented from time to time in subsequent filings. These risks and uncertainties include, without limitation: adverse capital and credit market conditions may significantly affect the company’s ability to meet liquidity needs, access to capital and cost of capital; conditions in the global capital markets and the economy generally; volatility or declines in the equity, bond or real estate markets; changes in interest rates or credit spreads or a sustained low interest rate environment; the company’s investment portfolio is subject to several risks that may diminish the value of its invested assets and the investment returns credited to customers; the company’s valuation of investments and the determination of the amount of allowances and impairments taken on such investments may include methodologies, estimations and assumptions that are subject to differing interpretations; any impairments of or valuation allowances against the company’s deferred tax assets; the company’s actual experience could differ significantly from its pricing and reserving assumptions; the pattern of amortizing the company’s DAC and other actuarial balances on its universal life-type insurance contracts, participating life insurance policies and certain investment contracts may change; the company may not be able to protect its intellectual property and may be subject to infringement claims; the company’s ability to pay stockholder dividends and meet its obligations may be constrained by the limitations on dividends or distributions Iowa insurance laws impose on Principal Life; changes in laws, regulations or accounting standards; results of litigation and regulatory investigations; from time to time the company may become subject to tax audits, tax litigation or similar proceedings, and as a result it may owe additional taxes, interest and penalties in amounts that may be material; applicable laws and the company’s certificate of incorporation and by-laws may discourage takeovers and business combinations that some stockholders might consider in their best interests; competition from companies that may have greater financial resources, broader arrays of products, higher ratings and stronger financial performance; a downgrade in the company’s financial strength or credit ratings; changes in investor preferences; inability to attract and retain qualified employees and sales representatives and develop new distribution sources; international business risks; fluctuations in foreign currency exchange rates; the company may need to fund deficiencies in its “Closed Block” assets that support participating ordinary life insurance policies that had a dividend scale in force at the time of Principal Life’s 1998 conversion into a stock life insurance company; the company’s reinsurers could default on their obligations or increase their rates; risks arising from acquisitions of businesses; and a computer system failure or security breach could disrupt the company’s business and damage its reputation.
