A stock split rescales your per-share ACB. A spin-off carves your cost base between two companies. A merger swaps your shares for new ones at a defined ratio. Get any of these wrong and every future gain on that holding is off. Sched3 applies each corporate action on the right date and carries the cost base through cleanly.
Enter the split, spin-off, or merger with its ratio and effective date — or apply a known event Sched3 recognizes for your holding.
Splits rescale per-share cost, spin-offs allocate cost base between the parent and the new shares, and mergers carry cost through the exchange ratio — each on the effective date.
Because the adjustment is applied in place, every subsequent sale measures the gain against a cost base that reflects the corporate action.
Sched3 models each action type with its own math, applied on the effective date and in the right order relative to your trades.
Each corporate action links to the event, its ratio, and the date it applied, so an accountant can see exactly how a holding’s cost base was carried through.
Corporate-action handling is part of the Active plan and flows into your ACB and capital-gains figures.

A split does not change your total cost base — only how it is spread across shares. In a 2-for-1 split you hold twice as many shares, each with half the previous per-share ACB. Your total cost and total value are unchanged, so no gain is triggered, but the per-share figure must be rescaled for future sales to be correct.
When a company spins off a subsidiary, a portion of your original adjusted cost base is allocated to the new shares based on a ratio the company publishes (often derived from relative fair market values). The parent’s ACB is reduced by the same amount. Sched3 applies that allocation so both holdings carry the right cost base.
It depends on the deal. Many share-for-share mergers qualify for a tax-deferred rollover, where your old cost base simply carries to the new shares at the exchange ratio. Cash-and-share deals can trigger a partial gain. Sched3 carries the cost base through the exchange ratio; whether a rollover applies is a question for your accountant on the specific transaction.
