DES MOINES, Iowa -- January 31, 2013

The Principal Riverwalk  is now officially complete, allowing visitors to
walk, run, bike and skate in a beautiful and natural outdoor setting. The year
end 2012 completion is just in time to give people new motivation to keep
their New Year’s resolutions. The project began in 2004 as a gift to the City
of Des Moines in celebration of the Principal Financial Group^® 125^th
anniversary.

“Kicking off 2013 with the completion of the Principal Riverwalk can encourage
people to keep their New Year’s resolutions to be more fit, spend more time
with family or personal time for themselves,” says Mary O’Keefe, senior vice
president and chief marketing officer at The Principal^®. “Our long-term
vision for this project was to improve quality of life.  From entertainment to
activities, The Principal Riverwalk delivers the amenities to enrich
lifestyles throughout all four seasons.”

The Principal Riverwalk amenities can help with a few of the most common New
Year’s resolutions:

  *Spend time with friends and family: Nearly 200,000 visitors (to-date) have
    enjoyed the Brenton Skating Plaza. Ice skating, broomball and hockey are a
    few of the winter sport activities to enjoy. Weather permitting, the
    skating plaza will be open until mid-March.
  *Get fit: The 1.2 mile loop serves as a hub for the city’s numerous bike
    trails, connecting nearly 300 miles worth of trails in Central Iowa. The
    loop conveniently anchors four downtown Des Moines major attractions: the
    Botanical Center, the Court Avenue District, the Science Center of Iowa
    and the Iowa Events Center.
  *Slow down and do something just for you: Sitting riverside, communing with
    nature, or grabbing a snack or beverage when a new Hub Spot café is
    anticipated to open later this spring, outdoor activity can be enjoyed at
    any pace.
