BOSTON, Dec. 2, 2014 /PRNewswire/ -- As previously announced on November 14, 2014 by Atlantic Power Corporation ("Atlantic Power") and Atlantic Power Preferred Equity Ltd. ("Preferred Equity"), the dividend rate on Preferred Equity's outstanding Cumulative Rate Reset Preferred Shares, Series 2 (the "Series 2 Shares") will be reset on December 31, 2014, using a reset dividend rate (the "Reset Dividend Rate") calculated on December 1, 2014.

The Reset Dividend Rate was calculated on December 1, 2014 to be 5.57%, representing the sum of the Canadian Government five-year bond yield of 1.39% plus 4.18%.

Such Reset Dividend Rate will commence with the March 31, 2015 dividend payment to the holders of the Series 2 Shares and continue through the December 31, 2019 dividend payment to the holders of the Series 2 Shares, at which time such Reset Dividend Rate will again be reset.

On December 31, 2014 and again on December 31 of every fifth year thereafter, the holders of Series 2 Shares have the right to convert their Series 2 Shares, on a one-for-one basis, into Cumulative Floating Rate Preferred Shares (the "Series 3 Shares").

The Series 3 Shares dividend rate was calculated on December 1, 2014 to be 5.09%, representing the sum of the Canadian Government 90-day Treasury Bill yield (using the three-month average result of .91%) plus 4.18%.

Holders of Series 2 Shares who wish to convert such securities to Series 3 Shares should contact the financial institution, broker or other intermediary through which they hold the Series 2 Shares to exercise this conversion privilege. Notice of the exercise of the conversion privilege must be received by Preferred Equity not earlier than December 1, 2014 and not later than 5:00 p.m. (Toronto time) on December 16, 2014.

If after giving effect to all Election Notices, there would remain outstanding less than 1 million Series 2 Shares, then all remaining outstanding Series 2 Shares will automatically convert into Series 3 Shares, on a one-for-one basis on December 31, 2014. Holders of the Series 2 Shares will not be permitted to convert their Series 2 Shares into Series 3 Shares if, after giving effect to all Election Notices, there would be outstanding less than 1 million Series 3 Shares.

Inquiries should be directed to Preferred Equity's registrar and transfer agent, Computershare Trust Company of Canada, at (800) 564-6253.
