“Tangible net worth” means the value of all the assets, minus the value of all the liabilities, of a self-insured employer or an association of self-insured private employers except:
1. Goodwill or excess cost over the fair market value of assets.
2. Any other items listed in the assets that are deemed unacceptable by the Commissioner because they cannot be justified or because they do not directly support the ability of the self-insured employer or association to pay a claim.
