Disclaimers: The monthly reported unaudited, estimated Net Asset Value stated in this announcement has been prepared by the Administrator and reviewed by the Investment Manager. It may vary from the estimated weekly NAV announcements that are produced by the Administrator and reviewed by the Manager, which are based on estimated valuations. The estimated weekly NAV is provided for indicative purposes only. The Company accepts no responsibility for the accuracy of the estimated weekly NAV figure reported, and neither is any responsibility implied.

The unaudited, estimated monthly NAV is prepared based on the following valuation guidelines:

·      Listed equities are marked-to-market, based on the closing price of the last trading day of the prior month, provided by the Vietnam stock exchanges (the Ho Chi Minh Stock Exchange and the Hanoi Stock Exchange).

·      Unlisted securities include over-the-counter (OTC) traded securities and unlisted securities publicly traded on the Unlisted Public Companies Market (UPCOM) of the Hanoi Stock Exchange. These holdings are marked-to-market on the same basis as listed equities. Where this valuation approach is not available, unlisted securities valuations are based on the average of up to three independent broker quotes for the last trading day of the prior month, or where these are unavailable, the last available price.

·      Non-publicly traded investments, including private equity and direct real estate investments, and operating assets, are valued based on the last available valuation as approved by the Audit Committee which may be adjusted for any impairment, loss or disposal.

·      Cash is based on cash in the bank at the close of the prior month and may be adjusted for receivables and accruals.

·      The Vietnam Dong (VND) foreign exchange rate is based on the daily reference rate provided by Vietcombank as of the date of the monthly NAV. The British Sterling (GBP) and US Dollar (USD) exchange rates are based on the Reuters reference rate of the same day.
