When adding a new security on AdjustedCostBase.ca, you’re presented with two optional fields:
- Initial Shares
- Initial Adjusted Cost Base
The purpose of this feature is to allow you to specify initial values for the number of shares and the ACB if you’ve previously calculated your ACB using another method (with another tool, using a spreadsheet, or manually calculated). This can potentially save you from a lot of time spent on entering the entire history of transactions for a security.
These fields are not designed to replace the first transaction (i.e., the initial purchase) for a security. If you are using AdjustedCostBase.ca to enter all the transactions for a security (as opposed to entering an initial value calculated using another method) then you should (usually) enter the initial transaction as a “Buy” transaction and leave the “Initial Shares” and “Initial Adjusted Cost Base” fields blank.
With multiple portfolios, each security you add will be visible and available for transactions in all portfolios. However, the “Initial Shares” and “Initial Adjusted Cost Base” fields will be unique for each portfolio. When you set values for these fields, those values will only apply to the active portfolio. To edit the initial values for another portfolio, you’ll need to first switch portfolios and then edit the security.
