ISO

International Organization for Standardization

A non-governmental organization that sets standard codes for countries and currencies. ISO sets the ISO 3166 codes for countries and provinces, which are used in international banking transactions and shipping. Likewise, it sets the ISO 4217 codes for individual currencies. ISO has its headquarters in Geneva, Switzerland, and, because its standards are usually adopted into the law of member states, it is more powerful than most other NGOs.

Incentive stock option (ISO).

Corporate executives may be granted incentive stock options (ISOs), also called qualifying stock options. These options aren't taxed when they're granted or exercised, but only when the underlying shares are sold.

If, after exercising the options, participating executives keep the shares for the required period, any earnings from selling the shares are taxed at the owner's long-term capital gains rate.

However, stock option transactions may make sellers vulnerable to the alternative minimum tax (AMT).
