    Commenting on the markets, Sam Vecht and Emily Fletcher, representing the
    Investment Manager noted:

    In December, the Company's NAV rose by 1.5% lagging the MSCI Frontier benchmark
    by -1.2%. The Company ended the year up 7.8% outperforming its benchmark by
    5.1%. The MSCI Emerging Markets Index returned 0.2% and 11.2% over the same
    periods (all performance figures are on a US Dollar basis with net income
    reinvested).

    Performance drivers from the previous month carried over into December, with
    contribution being spread out across countries, sectors, and names.
    Off-benchmark Egyptian positioning was among the larger contributors. Cleopatra
    Hospital performed well gaining 36% during the month amid increasing confidence
    over their ability to pass-through pricing impacts from November's devaluation
    of the Egyptian Pound. Similarly, gold miner, Centamin, rose by 19% as currency
    depreciation lowered cash costs. An underweight to Argentina benefited the fund
    as the market struggled amid weak economic activity, the unexpected resignation
    of Finance Minister Prat-Gay, and the subsequent split of the Finance Ministry
    into two separate arms. We used this weakness to add to our positions in the
    country. Our decision to not hold Vietnamese consumer staple, Vietnam Dairy,
    was the largest individual contributor to relative performance for the period.
    The stock fell by 9% due to a combination of uncertainty surrounding how the
    country's export-focused economy will be impacted by trade shocks due to
    President-Elect Trump's potentially protectionist policies, as well as a missed
    target for the firm's secondary offering amid highly restrictive investment
    caps.

    On the other hand our short oil positioning, specifically through longstanding
    underweights to the Middle East region detracted on a relative basis, as
    announcements for further production cuts by both OPEC and non-OPEC members
    caused oil prices to rally up to $55 per barrel. Specifically, the decision to
    hold a substantial underweight in Kuwait and Oman, were among the largest
    detractors. Similarly, although our Pakistani positions MCB Bank and DG Khan
    Cement were among the month's strongest performers, gaining 10% and 17%
    respectively, our underweight and more specifically, our decision to limit
    exposure to the country's energy names hurt the Trust's performance in
    aggregate. Broad selection within Morocco also weighed on returns, while a
    position in Caribbean wholesale market operator, Pricesmart, was the largest
    individual detractor.

    Despite the year-end volatility stemming from US elections, Frontier Markets
    continue to exhibit strong GDP growth and low government debt levels, and
    represent an opportunity to invest in companies with strong cash flow and high
    dividend yields, on some of the lowest valuations in the world.
