QUANTUMONLINE.COM SECURITY DESCRIPTION:  Argo Group International Holdings, Ltd. 7.00% Depositary Shares each representing a 1/1000 interest in a share of the 7.00% Resettable Fixed Rate Preference Shares, liquidation preference $25 per Depositary share, redeemable at the issuer's option on 09/15/2025 and every September 15th in every fifth year thereafter at $25 per Depositary share plus declared and unpaid dividends, and with no stated maturity. Non-cumulative distributions of the Annual Fixed Dividend Rate will be paid quarterly on 3/15, 6/15, 9/15 & 12/15 to holders of record on the 15th calendar day before that dividend payment date or such other record date fixed by the board, not more than 30 days or less than 10 days prior to the payment date (NOTE: the ex-dividend date is one business day prior to the record date). The Annual Fixed Dividend Rate will be 7.00% until the first redemption date, then it will be equal to the sum of the Five-year U.S. Treasury Rate on the applicable fixed rate calculation date plus 6.712%, resetting every 5 years thereafter on applicable fixed rate calculation date (see prospectus for more details). The dividends are non-cumulative and if the board of directors does not declare a dividend or the company fails to pay a dividend declared by the board for any quarterly dividend period, the holder will not be entitled to receive any dividend for that quarterly period and the undeclared or unpaid dividend will not accumulate. 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-51 of the prospectus for further information). The Company may redeem the Depositary Shares outside of the call period at $26 (104%) of their principal amount plus declared and unpaid dividends, if a change of control event occurs. The Company may redeem the Depositary Shares outside of the call period at $25.50 (102%) of their principal amount plus declared and unpaid dividends, if a Tax event occurs; outside of the call period at $25.50 (102%) of their principal amount plus accrued and unpaid dividends if a rating agency event occurs. The Company may redeem the Depositary Shares outside of the call period at $25 (100%) of their principal amount plus accrued and unpaid dividends, if a regulatory capital event occurs (see prospectus for further information). This security was rated as Not rated by Moody’s and rated BB by S&P at the date of its IPO. In regard to the payment of dividends and upon liquidation, the preference shares rank junior to the company's senior and preferred debt, equally with other preference shares of the company, and senior to the common shares of the company.
