Principal Variable Universal Life IncomeSM Plus Performance Update

As of July 19, 2008, this product is no longer available for new sales.

The investment results shown represent historical returns based upon the assumption VUL Income Plus was available for the periods shown. Past performance is no guarantee of future results. Since the investment results and unit values of the divisions will fluctuate, the policy's accumulated value may at any time be more or less than the total premiums paid under the contract, including upon surrender of the contract.

Returns shown reflect all investment management charges and any miscellaneous expenses incurred by the underlying accounts of the divisions. Returns do not include premium expense charges and various monthly deductions (administration charges, cost of insurance and mortality and expense risks charges) that vary by contract. In addition, results do not reflect the premium expense charge or the surrender charge levied if the policy is surrendered during the first 10 policy years, or within 10 years after a face amount increase. If these fees and charges had been deducted, the results shown would be significantly lower. These charges are explained fully in the prospectus, and their effect upon cash surrender values is best explained by reviewing several hypothetical illustrations contained in the prospectus. For a personalized illustration of historical performance that reflects the cost of insurance protection, contact your Registered Representative.
