Absolutely incredible. This article is one of, if not the single best explanation of dividend payout ratios and how investors from novice to professional can understand each company's current as well as prospective ability to not only maintain but also to increase the dividend it pays to shareholders. How anyone could criticize this very educational article is beyond belief.    
When I Googled "ACFFO calculations" the first three articles had nothing to do with Enbridge or JH (regardless of what some dividend adversaries say) and the articles that followed that simply used Enbridge to explain the statistical analysis and why using this statistically proven approach benefits rational investors. In no way were any of these articles meant to promote a stock.  
"Heading them off at the pass?"  No. This article is strictly a great educational piece for those who care about continued learning, becoming more knowledgeable and through this, better investors. 
Not for all, huh Cat?
