Recording a Corporate Action (i.e. Spin-Off)

Corporate actions are special events that affect a company’s stock. An example of a corporate action is a corporate spin-off, in which the parent company splits off part of itself (such as one of its divisions) into a separate business.

Corporate actions have repercussions on the company’s stock. In the case of a corporate spin-off, the change is typically to the cost basis of the stock. Other types of corporate actions can affect the number of shares.

To handle these situations, StockMarketEye provides the Corporate Action transaction type. This transaction type allows you to modify the cost basis of your holdings and/or change the number of shares you own. It is similar to a stock split, but has the extra dimension of being able to change the cost basis.


Although it is possible to record a stock split using a Corporate Action transaction, we recommend that actual stock splits (2-for-1, 1-for-7 reverse split, etc.) be recorded with a stock split transaction, rather than as a corporate action. See the documentation on recording a stock split for more details.

How A Corporate Spin-Off Works

In a typical corporate spin-off, the company splits itself into 2 separate entities – the original parent company and the newly spun-off company. Shares in the newly spun-off company are given to owners of the parent company’s stock. If you owned shares of the parent company at the time of the spin-off, you would end up owning shares of both companies after the spin-off.

The total value of your investment in the parent company before the spin-off is the same as the value of your investment in both the parent company and the spun-off company after the spin-off. This is because, even though the number of shares you own in the parent company does not change, the cost basis of those shares changes by the value of the spun-off company.

For example, let’s say you owned 100 shares of Company A. On Monday, Company A is trading at $10 per share so your investment in Company A is worth $1000.

On Tuesday, Company A spins-off one of its divisions into Company B. Company A says that for each 10 shares of Company A that you own, you will be given 3 shares in Company B. It also says that Company B made up 30% of its total value so the value of Company A’s shares will be reduced by 30%.

Due to the 30% reduction in Company A’s value, their shares on Tuesday trade at $7 per share. Your investment in Company A is now worth $700. Company B’s shares on Tuesday trade at $10 per share. You received 30 shares in Company B, which are now worth $300. The total value of your investment is still $1000, but is now divided between Company A’s and Company B’s shares.

Modifying A Corporate Action Transaction

You can modify a corporate action transaction just as you would any other transaction in StockMarketEye. Simply double-click on the transaction in the Transactions report to open the Details window.

After you have modified the transaction, you may need to re-build your portfolio (Prices view) from the transactions. This is because undoing and re-doing the effects a corporate action can, depending on the changed values, cause discrepancies between the Prices view and the Transactions.

To rebuild the Prices view from the Transactions, follow the steps in the section Rebuild Your Portfolio From Its Transactions.
