However, when the business operations of the three JR companies described above became stabilized and listed their shares on the Tokyo Stock Exchange and others came into sight, the following problems arose: With the lending fees being paid corresponding to the amount of traffic, the business operation efforts of each company could not be reflected in its business performance, and the amounts of assets and liabilities could not be fixed.
しかし、前記JR3社の経営が安定化して、東京証券取引所などへの株式公開が視野に入ると、輸送量に応じて貸し賃が変わるこの制度のままでは会社の営業努力が反映されないことや、各社の資産・債務の額が確定できないことなどが問題視されるようになった。
