       PRINCIPAL FINANCIAL GROUP, INC. REPORTS FOURTH QUARTER 2006 RESULTS

Des Moines, IA (February 5, 2007) - Principal  Financial Group, Inc. (NYSE: PFG)
today announced net income available to common stockholders for the three months
ended December 31, 2006, of $284.1 million,  or $1.04 per diluted share compared
to $246.9  million,  or $0.87 per  diluted  share  for the  three  months  ended
December 31, 2005. The company reported operating earnings of $252.0 million for
fourth  quarter  2006,  compared  to $217.9  million  for fourth  quarter  2005.
Operating  earnings per diluted  share (EPS) for fourth  quarter 2006 were $0.93
compared to $0.77 for the same  period in 2005.  Operating  revenues  for fourth
quarter 2006 were a record $2,537.0 million compared to $2,481.1 million for the
same period last year.(1)

"The fourth quarter was a very strong finish for The Principal,  with 16 percent
growth in operating  earnings  contributing to a 13 percent increase in earnings
for the year," said J. Barry  Griswell,  chairman and chief  executive  officer.
"Driven by record  earnings for U.S. Asset  Management and  Accumulation,  which
improved  $107 million or 20 percent for the year,  and by  disciplined  capital
management,  the  company  delivered  19 percent  growth in  earnings  per share
compared to 2005."

"2006 marks an eighth consecutive year of record earnings for The Principal,  as
we continue to build an exceptional track record of performance," said Griswell.
"Since our IPO in 2001, we've achieved five-year  compounded annual growth of 11
percent for earnings and 17 percent for earnings per share.  We've also improved
return on equity  (ROE)(2) by 640 basis  points  since 2001,  to 15.3 percent at
year-end."

     Additional highlights for 2006 include:

     o    Record net income  available  to common  stockholders  (net income) of
          $1.03  billion,  and record net income per  diluted  share of $3.74 in
          2006.
     o    Record operating  earnings of $972.1 million,  and record EPS of $3.53
          in 2006.
     o    Record assets under management of $256.9 billion, up $61.7 billion, or
          32 percent from 2005(3).
     o    Record full service  accumulation  account values of $91.8 billion, up
          19 percent from 2005.
     o    Record  sales  of each  of the  company's  three  key  retirement  and
          investment products in 2006, including: $3.8 billion for mutual funds,
          up 12 percent; $2.5 billion for individual  annuities,  up 25 percent;
          and $7.2 billion for organic full service accumulation, up 18 percent,
          including $1.9 billion in the fourth quarter.

"Strong  results in 2006 reflect our ongoing focus on  fundamentals - innovative
retirement and employee benefits solutions,  responsive service, and exceptional
convenience, choice and value," said Griswell. "During the year, we continued to
help employers understand benefit trends and employee retention strategies,  and


                                       3


to broaden our array of high quality,  cost effective benefits.  We continued to
help captive and independent  distribution alike, through new product education,
additional  needs analysis tools,  and point of sale expertise.  And we expanded
our portfolio of worksite solutions, adding an array of product offerings, tools
and personalized  guidance to help employees assess needs, evaluate options, and
execute a tailored financial plan."

"Our ongoing  investment in helping  customers  achieve  financial  security and
success  continues to drive solid retention and sales. In our largest  business,
full service accumulation,  we achieved 94 percent  employer-level  retention in
2006 and our retention of at-risk  participant assets continued to significantly
outpace the industry average," said Griswell. "Sales of our three key retirement
and investment products - full service accumulation, mutual funds and individual
annuities - each reached  record  levels,  combining  for $13.5  billion for the
year, an increase of 18 percent from 2005. We also achieved a fifth  consecutive
year of record  sales in our  Specialty  Benefits  division,  an  increase of 21
percent."

"Looking ahead, we remain highly optimistic about the  opportunities  that exist
across our  businesses,  and our ability to translate those  opportunities  into
growth,"  said  Griswell.  "We've built a strong  foundation  for success:  deep
experience  meeting the benefit needs of growing businesses and their employees;
a broad array of asset accumulation and retirement income management  solutions;
and unique expertise managing assets appropriate for retirement investors. We'll
continue  to strive to  leverage  these  competitive  strengths,  to execute our
customer-focused strategy, and to create long-term value for our shareholders."

                               SEGMENT HIGHLIGHTS

U.S. ASSET MANAGEMENT AND ACCUMULATION

Segment operating earnings for fourth quarter 2006 were a record $178.7 million,
compared  to  $136.0  million  for  the  same  period  in  2005.   Full  service
accumulation  generated  record  earnings  of $78.8  million,  compared to $64.8
million in fourth  quarter 2005,  reflecting  increased fees from higher account
values.  Full  service  accumulation  account  values  were $91.8  billion as of
December 31, 2006, compared to $77.3 billion as of December 31, 2005.  Principal
Global  Investors  generated  record  earnings of $32.1 million for the quarter,
compared to $18.7 million in fourth  quarter  2005,  primarily due to management
fee growth in all lines.

Operating revenues for the fourth quarter increased to a record $1,212.2 million
compared to $1,205.7  million for the same period in 2005.  Lower single premium
group annuity sales were more than offset by double-digit  revenue growth in all
other businesses  within the segment.  The single premium group annuity product,
typically  used to fund defined  benefit plan  terminations,  can generate large
premiums  from a small  number of  customers  and  tends to vary from  period to
period.   Excluding  this  product,   segment  revenues  increased  15  percent,
reflecting record revenues for full service accumulation,  individual annuities,
investment only, and Principal Global Investors.

                                       4


Segment assets under  management  reached a record $221.9 billion as of December
31, 2006, up 35 percent from $164.3  billion as of December 31, 2005.  Excluding
the purchase of WM Advisors,  Inc., segment assets under management increased 18
percent from December 31, 2005.

INTERNATIONAL ASSET MANAGEMENT AND ACCUMULATION

Segment  operating  earnings for fourth  quarter 2006 were $14.9  million.  This
compares to $22.7 million of earnings for fourth quarter 2005, which included an
$8.7 million tax benefit associated with the liquidation of defined contribution
operations in Japan. Fourth quarter 2006 earnings included a net benefit of $0.8
million,  as tax  benefits of $5.9  million  were  substantially  offset by $5.1
million  of  other  items,  primarily  deflation  in  Chile  and  organizational
restructuring costs.

Operating  revenues were $128.6  million for fourth  quarter  2006,  compared to
$165.1 million for the same period last year. The decline in operating revenues,
primarily  the  result of  deflation  in Chile,  was  substantially  offset by a
corresponding decline in benefits and claims expenses.

Assets  under  management  for the  segment  were a record  $19.1  billion as of
December 31, 2006, compared to $15.4 billion as of December 31, 2005.

LIFE AND HEALTH INSURANCE

Segment operating earnings for fourth quarter 2006 were $64.9 million,  compared
to $63.2 million for the same period in 2005.  Individual Life division earnings
were $30.4  million,  compared to $25.0  million for fourth  quarter  2005.  The
increase from a year ago primarily  reflects  normal  fluctuations in experience
between periods.  Specialty  Benefits  division  earnings were $21.4 million,  a
decline of $0.4  million.  In fourth  quarter  2006,  growth in premium  for the
division,  and a  $2.9  million  benefit  to  earnings  from a  group  long-term
disability  reserve  refinement,  were  offset by  higher  loss  ratios.  Health
division  earnings  were $13.1  million,  compared  to $16.4  million for fourth
quarter 2005. The decline  primarily  reflects  worsened loss ratios compared to
the year ago period.

Operating revenues were $1,210.1 million, a ninth consecutive record quarter for
the  segment,  and an  increase of eight  percent  from the same period in 2005.
Specialty  Benefits  revenues  increased 15 percent,  driven by strong sales and
steady retention in all of the division's lines. Health revenues increased eight
percent,  reflecting  member growth in the division's  target markets and higher
premium  per  member.  Individual  Life  revenues  increased  slightly,  due  to
increasing fees from universal life and variable universal life products.


                                       5


CORPORATE AND OTHER

Operating  losses  for  fourth  quarter  2006 were  $6.5  million,  compared  to
operating  losses of $4.0  million for the same period in 2005.  Fourth  quarter
2005 results reflect higher operating earnings from joint venture real estate.

FORWARD LOOKING AND CAUTIONARY STATEMENTS
This press  release  contains  forward-looking  statements,  including,  without
limitation,  statements  as to sales  targets,  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  December  31,  2005,  and in the
company's  quarterly  report on Form 10-Q for the quarter  ended  September  30,
2006,  filed by the company with the Securities and Exchange  Commission.  These
risks  and  uncertainties  include,  without  limitation:  competitive  factors;
volatility  of financial  markets;  decrease in ratings;  interest rate changes;
inability to attract and retain sales  representatives;  international  business
risks; foreign currency exchange rate fluctuations; a pandemic, terrorist attack
or  other  catastrophic  event;  default  of  the  company's  re-insurers;   and
investment portfolio risks.

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 measures,  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, determining employee and senior management awards and
compensation,  and evaluating  performance on a basis comparable to that used by
investors and securities analysts.

SHARE REPURCHASES
In May 2006, following the Board's share repurchase  authorization of up to $500
million,  the  company  entered  into an  accelerated  common  stock  repurchase
agreement with an investment bank.  Under this agreement,  the company paid $500
million and received an initial  delivery of 7.67 million common  shares,  while
retaining the right to receive  additional common shares depending on the volume
weighted  average share price of the  company's  common stock over the program's
execution  period.  The program was completed during the fourth quarter 2006, at
which time the company  received  1.67  million  additional  common  shares.  On
November 28, 2006, the Board  authorized the repurchase of up to $250 million of
our  outstanding  common  stock.  The  company  began  activity  under  the  new
authorization  with the repurchase of approximately  $33 million of common stock
during the month ending January 31, 2007.

*OPERATING  EARNINGS  VERSUS  U.S.  GAAP (GAAP) NET INCOME  AVAILABLE  TO COMMON
STOCKHOLDERS
Management   uses  operating   earnings,   which  excludes  the  effect  of  net
realized/unrealized  capital gains and losses, as adjusted,  and other after-tax
adjustments, for goal setting, determining employee compensation, and evaluating
performance  on a basis  comparable  to that used by  investors  and  securities
analysts.  Segment operating  earnings are determined by adjusting U.S. GAAP net
income  available to common  stockholders  for net  realized/unrealized  capital
gains and losses,  as  adjusted,  and other  after-tax  adjustments  the company
believes are not indicative of overall  operating  trends.  Note: it is possible
these  adjusting  items  have  occurred  in the past and  could  recur in future
reporting  periods.   While  these  items  may  be  significant   components  in
understanding and assessing our consolidated financial  performance,  management
believes  the   presentation  of  segment   operating   earnings   enhances  the
understanding of our results of operations by highlighting earnings attributable
to the normal, ongoing operations of the company's businesses.
