Algonquin Power & Utilities Corp. Announces Liberty Water Co. Private Placement Debt Financing

OAKVILLE, ON, Dec. 13 /CNW/—Algonquin Power & Utilities Corp. (“APUC”) (TSX: AQN) today announced a $50 million private placement debt financing commitment for its subsidiary, Liberty Water Co. (“Liberty Water”). The notes are senior unsecured with a ten year final, 8.8 year average life maturity and will bear interest at 5.6%. Liberty Water will apply proceeds from the notes to repay intercompany debt to APUC.

“The private placement debt financing demonstrates our continuing ability to arrange attractive debt for our regulated utilities businesses”, commented Ian Robertson, Chief Executive Officer. “The completion of this financing introduces longer-term debt and an increase in US dollar denominated debt, consistent with our re-financing strategy to seek a capital structure aligned with our North American power and utilities businesses.”
