The average well production rate has decreased from **166 barrels per day** in 2018 to **157** in 2022[12](index=12&type=chunk)[325](index=325&type=chunk) Net Production Allocated to 1989 Working Interests (thousand barrels per day) | Calendar Year | Oil | Condensate | | :--- | :--- | :--- | | 2018 | 77.3 | 0.0 | | 2019 | 75.5 | 0.0 | | 2020 | 74.0 | 0.0 | | 2021 | 70.6 | 0.0 | | 2022 | 69.5 | 0.0 | - Based on the 2022 average WTI price of **$93.67/barrel**, HNS estimates that royalty payments to the Trust will cease after **2024**. Consequently, no proved reserves are attributed to the Trust beyond that date[57](index=57&type=chunk)[11](index=11&type=chunk)[201](index=201&type=chunk) [Certain Tax Considerations](index=18&type=section&id=CERTAIN%20TAX%20CONSIDERATIONS) The Trust is a grantor trust, not directly taxable, with unitholders reporting income and deductions, and foreign unitholders subject to a 30% withholding tax - The Trust is a grantor trust, not a taxable entity. Unitholders must report their share of Trust income and deductions on their own tax returns[211](index=211&type=chunk) - Foreign unitholders are typically subject to a **30%** withholding tax on gross income from the Royalty Interest, though a lower treaty rate may apply[184](index=184&type=chunk) - The Trustee considers the Trust a widely held fixed investment trust (WHFIT) for U.S. Federal income tax purposes and provides tax information accordingly[148](index=148&type=chunk) [ITEM 1A. RISK FACTORS](index=22&type=section&id=ITEM%201A%2E%20RISK%20FACTORS) The Trust faces significant risks from WTI price volatility, declining production, operational disruptions, rising inflation, and potential termination due to low net revenues [Risks Related To Royalty Payments](index=22&type=section&id=Risks%20Related%20To%20Royalty%20Payments) Royalty payments are uncertain due to WTI prices and rising costs, with past cessations and a **$6.0 million** cash reserve maintained by the Trustee to cover expenses - The Trust did not receive any royalty payments for the four quarters of **2020** and the first quarter of **2021** due to low WTI prices, and payments may cease again in the future[218](index=218&type=chunk) - The Trust will terminate if net revenues are less than **$1,000,000** for two consecutive years. This condition was met for **2020**, making termination a possibility[61](index=61&type=chunk)[220](index=220&type=chunk) - The Trustee intends to maintain a cash reserve of at least **$6,000,000** to pay for administrative and termination expenses, which may reduce or eliminate distributions to unitholders even if royalty payments are received[59](index=59&type=chunk)[219](index=219&type=chunk) [Risks Related to WTI Price](index=24&type=section&id=Risks%20Related%20To%20WTI%20Price) WTI crude oil prices are highly volatile due to global factors, directly impacting Trust revenues and reserve estimates, while inflation further reduces royalty payments - Crude oil prices are subject to wide swings due to factors like economic activity, geopolitical events (e.g., Russia's war with Ukraine), OPEC+ decisions, and the strength of the U.S. dollar[9](index=9&type=chunk)[361](index=361&type=chunk) - High inflation, as measured by the Consumer Price Index, increases the Cost Adjustment Factor, which in turn reduces the Per Barrel Royalty and negatively affects distributions[380](index=380&type=chunk) - Government policies aimed at reducing greenhouse gas emissions and promoting green energy could decrease demand for oil, negatively affecting the WTI price and Trust revenues[384](index=384&type=chunk) [Risks Related to Oil Production](index=25&type=section&id=Risks%20Related%20To%20Oil%20Production) Prudhoe Bay production is declining, HNS has no obligation to maintain it, and the Trans-Alaska Pipeline System (TAPS) faces risks that could halt all production - Production from the Prudhoe Bay field is declining and is expected to continue to do so.
