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-generatingbusinesses 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 investmenttrusts (REITs); energy trusts; and power, pipeline, and utility trusts.

Income Deposit Security (IDS)

An exchange-traded, fixed income-like instrument consisting of a subordinateddebt security and a share of common stock packaged together to form a tax-efficient delivery mechanism to distribute an issuer's free cash flow to its investors. Investors are paid dividends from the commonshare component and interest from the subordinated debt. The structure was created for U.S.-based companies to replicate the economic attributes of the Canadian income trust structure - providing steady, high-yield returns to U.S. and Canadian investors in U.S. companies. IDSs do not use the trust structure. Also known as income participating securities (IPS).
