BOL - Always underperforming

I’m sorry for being very naive about BOL. I looked at it once 5 years ago & now just briefly looked at it again.

I have no industry knowledge but I do understand numbers.

Whilst BOL have tried over many years to make a profit, it seems for some reason the business model will never make a respectableis Return on Capital (ROC). My rule basic rule of thumb is a business needs to make 10% on its net assets or its not a good business.

knowing this, why can’t BOL management start to seriously sell down a ,it of their Cranes and return capital to shareholders OR sell down cranes and redeploy capital in better hire/infrastructure businesses that can make a respectable ROC.

So I guess my main question for industry insiders that know what a crane is worth, how realisable and what kind of dollars would BOL get if they sold their assets over say 1-3 years?

thanks all and sorry for the long winded email.
