1:Start with the current margin and let it grow at a certain rate. 

2:Start with a positive margin of a mature firm at a future time point and work backwards year over year till the current negative margin. 

3:No need to forecast future margins because the firm will not survive in 1 year. 

4:Cannot forecast future margins at all
