A strategy of matching assets to future liabilities. That is, price immunization involves investing in certain securities with a certain expected return so that the investor will be able to pay for future liabilities.

Portfolios that practice price immunization usually invest in low-risk, investment-grade securities. See also: Portfolio dedication.
