We are revising our outlook on AltaLink Investments L.P. (AILP) and subsidiary AltaLink L.P. (ALP) to stable from negative. We are also affirming our ratings on the companies, including our 'A-' long-term corporate credit rating (CCR) on ALP and 'BBB-' CCR on AILP. The outlook revision on the companies reflects our view that the dependence on ultimate parent SNC-Lavalin Inc. is diminishing because ALP's large capital program is winding down, and we expect financial metrics to be robust enough within our outlook period to withstand additional potential leverage should equity support from SNC not be forthcoming. TORONTO (Standard&Poor's) Jan. 17, 2014--Standard&Poor's Rating Services today said it revised its outlooks on Calgary, Alta.-based AltaLink Investments L.P. (AILP)
