operating leases aren’t *reported* on the balance sheet, so we need to add the off-balance sheet items in, which are both an asset and a liability. if it were a finance lease then we wouldn’t have the adjustments to make.
or I could be completely wrong…? this is just my thinking it through
Operating lease need to be adjusted (add its PV to the balance sheet: asset, liability) to reflect accurately how it affect the ratios. So we treat operating lease as it was financial lease.
