Calculating WACC w/ Negative Equity

Sorry if this is the wrong place for this type of question (not sure which Level would be appropriate and figure GD has a mix of each one)… Simple question about finding the WACC of a company with a negative shareholder equity value (liabilities > assets). What weight do you give to debt and equity, respectively, in regards to the total enterprise value? Thanks,611132

Whoops, thanks Darien
