                                                         Segment Highlights 
Retirement and Investor Services 
  Segment operating earnings for fourth quarter 2011 were $131.9 million, compared to $151.0 million 
for the same period in 2010. Full Service Accumulation earnings decreased 16 percent from the year ago quarter 
to $63.9 million, reflecting higher non-deferrable sales compensation cost, less variable investment income from 
fewer real estate sales and higher costs for employee pension and other post-retirement benefits. Principal Funds 
earnings increased 1 percent from a year ago to $10.6 million, primarily due to an increase in average account 
values. Individual Annuities earnings were $30.0 million compared to $33.2 million for fourth quarter 2010. The 
variance primarily reflects spread compression. Bank and Trust Services earnings were $8.5 million compared to 
$8.7 million for the same period in 2010 primarily reflecting flat account values. The guaranteed businesses, 
which consists of Investment Only and Full Service Payout, earned $18.9 million in the fourth quarter 2011 
compared to $22.6 million in the fourth quarter of 2010. The difference was primarily due to lower variable 
investment income and a decline in average account values. 
  Operating revenues for the fourth quarter 2011 were $1,016.7 million compared to $1,093.4 million 
for the same period in 2010 primarily due to $74.4 million of lower revenues for the guaranteed businesses. 
  Segment assets under management were $179.8 billion as of Dec. 31, 2011, compared to $175.0 
billion as of Dec. 31, 2010. 
 
Principal Global Investors 
  Segment operating earnings for fourth quarter 2011 were $17.5 million, compared to $19.2 million in 
the prior year quarter, primarily due to higher compensation and one-time costs related to our acquisition of 
Origin Asset Management. 
  Operating revenues for fourth quarter were $151.8 million, compared to $135.3 million for the same 
period in 2010, primarily due to higher management fees and an increase in performance fees. 
  Unaffiliated assets under management were $82.4 billion as of Dec. 31, 2011, compared to $78.7 
billion as of Dec. 31, 2010. 

 



Page 6 
 
Principal International 
          Segment operating earnings were $51.4 million in fourth quarter 2011, compared to $30.9 million in 
the prior year quarter. Results reflect the successful integration of the HSBC AFORE acquisition and $10.4 
million of one-time earnings recognized in the quarter that are not expected to recur. 
          Operating revenues were $255.7 million for fourth quarter 2011, compared to $210.5 million for the 
same period last year, primarily due to 15 percent growth in assets under management. 
                Segment assets under management were a $52.8 billion as of Dec. 31, 2011 (excluding
approximately $7.2 billion of assets under management in our asset management joint venture in China, 
which are not included in reported assets under management), up $7.0 billion over $45.8 billion as of Dec. 31, 
2010. This includes a record $5.5 billion of net cash flows over the trailing twelve months, or 12 percent of 
beginning of period assets under management. 
 
U.S. Insurance Solutions 
          Segment operating earnings for fourth quarter 2011 were $59.3 million, compared to $52.3 million 
for the same period in 2010. Individual Life earnings were $33.2 million in the fourth quarter compared to 
$22.1 million in fourth quarter 2010. Fourth quarter 2010 results were reduced due to an increase in GAAP net 
reserves following a periodic long-term interest rate assumption review. Specialty Benefits earnings were $26.1 
million in fourth quarter 2011, down from $30.2 million in the same period a year ago, as growth in the 
business was offset by higher costs for employee pension and other post-retirement benefits and lower variable 
investment income. 
          Segment operating revenues for fourth quarter 2011 were $737.8 million compared to $705.0 
million for the same period a year ago due to higher premium and fees in Individual Life and positive trends 
in both sales and client retention for Specialty Benefits. 
 
Corporate 
          Operating losses for fourth quarter 2011 were $43.0 million compared to operating losses of $39.3 
million in fourth quarter 2010. Current quarter results reflect lower variable investment income from an active 
credit strategy on excess capital at the holding company. We unwound this strategy in January 2012 due to the 
added volatility and the continued deployment of excess capital at the holding company in 2011. 
 
Forward looking and cautionary statements 
This press release contains 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, 2010, and in the company’s quarterly report on Form 10-Q for the 
quarter ended Sept. 30, 2011, filed by the company with the 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; continued difficult conditions in the global capital markets 
and the economy generally; continued volatility or further declines in the equity markets; changes in interest 
rates or credit spreads; 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 securities may 
include methodologies, estimations and assumptions that are subject to differing interpretations; the 
determination of the amount of allowances and impairments taken on the company’s investments requires 
estimations and assumptions that are subject to differing interpretations; gross unrealized losses may be realized 
or result in future impairments; 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; inability to attract and retain sales representatives and develop new distribution 
sources; international business risks; the company’s actual experience could differ significantly from its pricing 
and reserving assumptions; 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; the 
pattern of amortizing the company’s DPAC and other actuarial balances on its universal life-type insurance 
contracts, participating life insurance policies and certain investment contracts may change; 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; changes in laws, regulations or accounting standards; a computer system failure or 
security breach could disrupt the company’s business, and damage its reputation; 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; fluctuations in foreign currency exchange rates; and applicable laws and the company’s stockholder 
rights plan, certificate of incorporation and by-laws may discourage takeovers and business combinations that 
some stockholders might consider in their best interests. 
 
Use of Non-GAAP Financial Measures 
The company uses a number of non-GAAP financial measures that management believes are useful to investors 
because they illustrate the performance of normal, ongoing operations, which is important in understanding and 
evaluating the company’s financial condition and results of operations. They are not, however, a substitute for 
U.S. GAAP financial measures. Therefore, the company has provided reconciliations of the non-GAAP 
measures to the most directly comparable U.S. GAAP measure at the end of the release. The company adjusts 
U.S. GAAP 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 the future reporting periods. Management also uses 
non-GAAP 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.
