The assets of the nation's four major highway-related public corporations were greater than their debts by a combined 5.95 trillion yen, with only one of them suffering a negative net worth, according to their balance sheets released Monday.

The four highway constructors and administrators are Japan Highway Public Corp., Metropolitan Expressway Public Corp., Hanshin Expressway Public Corp. and the Honshu-Shikoku Bridge Authority.

The financial statements attest that three of the four have a net worth in positive territory. The Honshu-Shikoku Bridge Authority has a negative net worth of 980 billion yen.
