the only reason breakeven is relevant for investors is that its about making money and avoiding further dilution.

corporate costs are costs - if business lines make money but corporate costs are greater than any amount made - the company still loses money and/or needs more funding

its a common complaint of mining companies that the operations make money but after corporate costs they often lose money or make very little

it does have some accounting functionality. so its not that it shouldnt be separated that way

but the only breakeven worthwhile to shareholders in the main is group breakeven
