Definition of Stock option

Stock option

An option in which the underlying is the common stock of a corporation.

stock option

a right allowing the holder to purchase shares of common stock during some future time frame and at a specified price

price no later than a specific date. It is a commonly used form of incentive compensation.

options.

Incentive Stock Option

An option to purchase company stock that is not taxable
to the employee at the time it is granted nor at the time when the employee
eventually exercises the option to buy stock.

Nonqualified Stock Option

A stock option not given any favorable tax treatment
under the Internal Revenue Code. The option is taxed when it is exercised,
based on the difference between the option price and the fair market
value of the stock on that day.

Stock index option

An option in which the underlying is a common stock index.

Expiration date

The last day (in the case of American-style) or the only day (in the case of European-style)
on which an option may be exercised. For stock options, this date is the Saturday immediately following the
3rd Friday of the expiration month; however, brokerage firms may set an earlier deadline for notification of
an option holder's intention to exercise. If Friday is a holiday, the last trading day will be the preceding
Thursday.

basic earnings per share (EPS)

This important ratio equals the net
income for a period (usually one year) divided by the number capital
stock shares issued by a business corporation. This ratio is so important
for publicly owned business corporations that it is included in the daily
stock trading tables published by the Wall Street Journal, the New York
Times, and other major newspapers. Despite being a rather straightforward
concept, there are several technical problems in calculating
earnings per share. Actually, two EPS ratios are needed for many businesses—
basic EPS, which uses the actual number of capital shares outstanding,
and diluted EPS, which takes into account additional shares of
stock that may be issued for stock options granted by a business and
other stock shares that a business is obligated to issue in the future.
Also, many businesses report not one but two net income figures—one
before extraordinary gains and losses were recorded in the period and a
second after deducting these nonrecurring gains and losses. Many business
corporations issue more than one class of capital stock, which
makes the calculation of their earnings per share even more complicated.

capital structure, or capitalization

Terms that refer to the combination of
capital sources that a business has tapped for investing in its assets—in
particular, the mix of its interest-bearing debt and its owners’ equity. In a
more sweeping sense, the terms also include appendages and other features
of the basic debt and equity instruments of a business. Such things
as stock options, stock warrants, and convertible features of preferred
stock and notes payable are included in the more inclusive sense of the
terms, as well as any debt-based and equity-based financial derivatives
issued by the business.

diluted earnings per share (EPS)

This measure of earnings per share
recognizes additional stock shares that may be issued in the future for
stock options and as may be required by other contracts a business has
entered into, such as convertible features in its debt securities and preferred
stock. Both basic earnings per share and, if applicable, diluted
earnings per share are reported by publicly owned business corporations.
Often the two EPS figures are not far apart, but in some cases the
gap is significant. Privately owned businesses do not have to report earnings
per share. See also basic earnings per share.

equity

Refers to one of the two basic sources of capital for a business, the
other being debt (borrowed money). Most often, it is called owners’
equity because it refers to the capital used by a business that “belongs”
to the ownership interests in the business. Owners’ equity arises from
two quite distinct sources: capital invested by the owners in the business
and profit (net income) earned by the business that is not distributed to
its owners (called retained earnings). Owners’ equity in our highly developed
and sophisticated economic and legal system can be very complex—
involving stock options, financial derivatives of all kinds, different
classes of stock, convertible debt, and so on.

Security

as a stock option or note payable.

Cash flow provided by operating
activities adjusted to provide a more recurring, sustainable measure. Adjustments to reported cash
provided by operating activities are made to remove such nonrecurring cash items as: the operating

exchange. A basket option is generally used by multinational corporations with multicurrency cash flows
since it is generally cheaper to buy an option on a basket of currencies than to buy individual options on each
of the currencies that make up the basket.

Beta equation (Stocks)
