Thanks for your thoughts petec, especially re the Panama canal. I have heard Atlas allude to this in calls but not explain it in that detail (or I didn't pick up on it). Are there any other sources/data you can share for this - particularly on your comment "the limits on ship size are imposed by port capacity and journey length (you can't use huge ships on short journeys because the dwell time in ports is too long)"
Their corporate debt is basically split ~20% revolver, ~60% TL, and the rest FFH notes, and scheduled repayments are a few hundred m/year. But I take your points and think you're putting out better ones than me.
On your MidAmerican question: "15/0.73=20x eps in 18 years for a CAGR of 18%, partly driven by an increase in leverage? That seem fair?"
It's fair to say that though he was likely also responsible for the ~2x increase in earnings from 1990 to 1991 too (he cut 25% of employees in the first few months of 1991, and started a few-year trend of increased load factors on the geothermal plants)...but I don't know if they raised equity in 1991. Anyway, it's a good record however which way you cut it, and it is more anomalous that he did that while also substantially improving the business quality.
