To track most insurance-based investment vehicles, you can create a new Investment account. Creating a new investment account will allow you to report on income, capital gains, and performance. Since the securities in these accounts are not exchange traded, price updates cannot be downloaded.
You will need to manually update the prices and holdings in your account register. (Prices can also be updated from the Portfolio View.)
