Enbridge Energy witnessed sharp downward estimate revisions after reporting disappointing fourth-quarter 2012 results. The partnership reported fourth-quarter 2012 adjusted earnings of 18 cents per unit, missing the Zacks Consensus Estimate of 26 cents. Notably, Enbridge Energy's distribution growth prospects are closely linked to the successful completion of organic growth projects, which in turn might be adversely affected by operational hindrance, cost inflations and overruns, as well as delays in completion.
