For calculating TIE ratio (EBIT/Interest expense) should we use EBIT after unusual expense, or (EBIT after unusual expense+unusual expense), snce only EBIT after unusual expense is in the income statement ?

And how would EBITDA coverage ratio be calculated? ((EBITDA+Lease payments)/(Interest+Principal p.+Lease p.)
