Claims against Hanjin Heavy Industries and Construction Philippines (HHIC-Phil) stand at $1.71bn.
This is according to the restructuring shipbuilder's receiver, Rosario Bernaldo.
She said she had yet to receive a firm business proposal for the site in Subic Bay, Business World reported.
Validated claims and those without documents total $975m, while contingent claims amount to $735m.
Domestic banks are owed $450m of the total.
Contingent claims are covered by contracts that entitle a pay-off under certain conditions.
Ports giant ICTSI has expressed interest in taking over the company to establish a multi-purpose terminal.
HHIC-Phil sought court rehabilitation earlier this year after defaulting on loans.
Its parent Korean company was later taken over by creditors.
