About Atrium Mortgage Investment Corp.

Atrium is a non-bank provider of residential and commercial mortgages that lends in major urban centres in Canada, where the stability and liquidity of real estate are high. Atrium's objectives are to provide its shareholders with stable and secure dividends and preserve shareholders equity by lending within conservative risk limits.

Atrium is a mortgage investment corporation (MIC) as defined in the Canada Income Tax Act, so it is not taxed on income provided that its taxable income is paid to its shareholders in the form of dividends within 90 days after Dec. 31 each year. Such dividends are generally treated by shareholders as interest income, so that each shareholder is in the same position as if the mortgage investments made by the company had been made directly by the shareholder.
