Is the greentrains transaction legal ?
Wouldn't it have made the CXG sales revenue and profit greater than it would otherwise have been ?
Why was it done anyway ?
If Gemco / Cootes had taken on the debt to own the loco's / wagons would that have scared the market ?
Maybe Coote / Gemco could not raise the finance ?
What was the logic of Greentrains placing an order and accepting delivery of goods for which they had not arranged finance ?
Would it be normal for a public company to check the credit worthiness of a customer making such a material purchase ?
Many questions ????
