QUANTUMONLINE.COM SECURITY DESCRIPTION:  Atlas Corp, formerly Seaspan Corp., 8.20% Series G Cumulative Redeemable Perpetual Preferred Shares, liquidation preference $25 per share, redeemable at the issuer's option on or after 6/16/2021 at $25 per share plus accrued and unpaid dividends, and with no stated maturity.

Dividends paid by these preference shares are eligible for the preferential income tax rate of 15% to a maximum of 20% depending on the holder's tax bracket (and under IRS specified holding restrictions) but, since they are issued by a foreign company, are NOT eligible for the dividends received deduction for corporate holders (see page S-99 of the prospectus for further information). This security was not rated by Moody’s or S&P at the time of its IPO. In regard to the payment of dividends and upon liquidation, the preferred shares rank junior to the company's senior debt, equally with other preferreds of the company, and senior to the common shares of the company.
