Income Trust

Also called income funds. Income trusts are trusts structured to own debt and equity of an underlying entity, which carries on an active business, or has royalty revenues generated by the assets of an active business. By owning securities or assets of an underlying business, an income trust is structured to distribute cash flows, typically on a monthly basis, from those businesses to unit holders in a tax-efficient manner. The trust structure is typically utilized by mature, stable, sustainable, cash-generating businesses that require a limited amount of maintenance capital expenditures. An income trust is an exchange-traded equity investment that is similar to a common share. There are four categories of income trusts: business trusts; real estate investment trusts (REITs); energy trusts; and power, pipeline, and utility trusts.

Implied Volatility

A measurement of the volatility of a stock. Current price rather than historical price is used. Generally, if the price of an option rises without a corresponding rise in the underlying equity, implied volatility is considered to have risen.

Improving the Market

An order that either raises the bid price or lowers the offering price is said to be improving the market. The market improves because the spread between the bid and offer decreases.

Income Deposit Security (IDS)
