typically report on a REIT's NAV when the company reports it. Variable insurance and variable annuity contracts Variable universal life insurance policies and variable annuity contracts often are structured somewhat similarly to mutual funds, and they may vary in value as securities and markets fluctuate. Typically, these insurance or annuity products issue "units" of ownership to policyholders/annuitants in exchange for their investment—similar to shares of a mutual fund. Also similar to a fund, the assets, liabilities, and net assets of these product entities are valued periodically, resulting in an asset unit value or AUV or UAV per share, which is similar to NAV for a fund.
