Corporate Actions
Corporate Actions support three cases: Conversion, Share Allocation, and Delisting.
What it is, when to use it, and when not to
A Corporate Action is for events where your position changes because of an issuer action or broker reorganization, not because you made a regular market transaction.
Use BUY / SELL when
- You buy shares on the market and pay cash for them.
- You sell shares on the market and receive sale proceeds.
- Shares are forcibly sold or redeemed and you receive cash compensation.
Use Corporate Action when
- A conversion exchanges old shares for a new asset or convertible shares.
- A share allocation adds shares received from a spin-off or bonus issue.
- A delisting removes shares that were cancelled, written off, or removed without a market sale.
Why a corporate action is different
BUY and SELL describe your decision to buy or sell on the market. A Corporate Action usually results from a company, exchange, or broker decision and changes your shares without a regular market transaction.
- The event may be mandatory and independent of your buy or sell order.
- It may change the symbol, number of shares, or position structure without a typical execution price.
- Tax treatment may work differently than with a standard BUY or SELL.
Symbol Change: SQ -> XYZ
For a symbol-only change, the share count usually stays the same. Carry over the cost basis, meaning the original acquisition cost of the position, because it affects later gain, loss, and tax basis.
Conversion: LTS -> PKN
In the Lotos and Orlen merger, investors received 1.075 PKN shares for each 1 LTS share. Move the old total cost basis to the new shares, then calculate cost basis per PKN share as the old total cost divided by the number of PKN shares received.
Spin-off: SNT -> S2B
Use this example when Synektik shares grant you Syn2bio shares. If the broker shows the distribution with no acquisition cost, enter a symbolic 0.0001 cost basis so FundStat can create the position without materially affecting performance.
Delisting: Getin Noble Bank
Use this example when shares were removed from the account without a regular market sale and without cash compensation.
Current Limitation: Lots Are Not Split Automatically
Corporate Actions currently do not calculate separate lots for you.
- If you need lot-level accuracy, add multiple Corporate Action rows instead of one merged row.
- Use separate rows when different source lots should keep different cost basis values after the event.
- In practice, if one corporate action affects two or more lots, mirror that structure manually in FundStat.
