Atrium Mortgage Investment Corporation (TSX:AI) (TSX:AI.DB) (TSX:AI.DB.A) is pleased to announce that the underwriters of its offering of 6.25% convertible unsecured subordinated debentures due March 31, 2019 exercised, in part, their previously announced over-allotment option, resulting in the issue of an additional $1,801,000 aggregate principal amount of debentures. The partial exercise of the over-allotment option brings the total aggregate principal amount of such debentures issued by Atrium to $31,801,000. The debentures are listed on the Toronto Stock Exchange under the symbol "AI.DB.A".

The underwriting syndicate for the offering of debentures was bookrun by TD Securities Inc. and RBC Capital Markets and co-led by CIBC, and included BMO Capital Markets, Scotiabank, National Bank Financial Inc., Canaccord Genuity Corp., GMP Securities L.P., Raymond James Ltd., Industrial Alliance Securities Inc., Dundee Securities Ltd. and Mackie Research Capital Corporation.

Atrium will use the net proceeds from the partial exercise of the over-allotment option to repay existing indebtedness under its revolving operating credit facility, which will then be available to be drawn, as required, for general corporate purposes, particularly funding future mortgage loan opportunities.

The details of the debentures are described in Atrium's press release issued on February 27, 2014 in connection with the closing of the offering of the debentures.
