Donaco International (ASX:DNA) said an independent expert has been unable to complete its report in connection with On Nut Road's proposed acquisition of the firm, which has caused follow-on delays to the filing of a scheme booklet with the Australian Securities and Investments Commission for their review, according to a Friday Australian bourse filing.

It said that the dispatch of scheme booklets was delayed due to third parties taking longer than initially forecast to return valuation inputs to an independent expert, lengthier-than-expected analysis of change of control provisions under Cambodian and Vietnamese law, as well as holidays in Australia, Vietnam, and Cambodia.

It added that it would provide an updated timetable for the deal after an independent expert has completed its report, scheme booklets have been finalized, and updated court hearing dates have been confirmed.

Further, Donaco pays a mandatory contribution of 7% of its gross gaming revenue at Donaco Star Vegas to the Cambodian Commercial Gambling Management Commission, as part of its gaming license. Since Dec. 30, 2022, there was potential for a further 10% value-added tax, among other taxes, to also apply to gross gaming revenue of all commercial gambling companies in Cambodia.

Legal advice to clarify the firm's ongoing tax liabilities made it clear that a liability to pay the new tax on gross gaming revenue exists in respect of gaming revenue earned since Jan. 1.

If the liability materializes, Donaco estimates additional tax payable in the fiscal third quarter would be in the order of AU$666,000.

Its shares fell over 3% in recent trading on Friday.
