Because only a few regulations implementing the straddle rules have been promulgated, the consequences of such transactions to the Funds are not entirely clear. The straddle rules may increase the amount of short-term capital gain realized by a Fund, which is taxed as ordinary income when distributed to shareholders. Because application of the straddle rules may affect the character of gains or losses, defer losses and/or accelerate the recognition of gains or losses from the affected straddle positions, the amount which must be distributed to shareholders as ordinary income or long-term capital gain may be increased or decreased substantially as compared to a Fund that did not engage in such transactions.
The price of bitcoin may change sharply while the market for certain Bitcoin Instruments is closed or when the exchange on which Fund shares are traded is closed. Although the Funds will not invest directly in bitcoin, such price changes could impact the price and volatility of the Bitcoin Instruments in which the Funds invest and, therefore, could have a negative impact on your investment in the Funds.

A Fund’s current obligations under most swap agreements (total return swaps, equity/index swaps, interest rate swaps) will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by segregating or earmarking cash or other assets determined to be liquid, but typically no payments will be made until the settlement date. In connection with CDS in which a Fund is a “buyer”, the Fund will segregate or earmark cash or assets determined to be liquid by the Advisor, with a value at least equal to the Fund’s maximum potential exposure under the swap (e.g., any accrued but unpaid net amounts owed by the Fund to any clearinghouse counterparty). In connection with CDS in which a Fund is a “seller”, however, the Fund will segregate or earmark cash or assets determined to be liquid by the Advisor, with a value at least equal to the full notional amount of the swap (minus any variation margin or amounts owed to the Fund under an offsetting cleared transaction). This segregation or earmarking is intended to ensure that a Fund has assets available to satisfy its potential obligations with respect to the transaction. Each Fund reserves the right to modify its asset segregation policies in the future, including modifications to comply with any changes in the positions articulated by the SEC or its staff regarding asset segregation. Swap agreements that cannot be terminated in the ordinary course of business within seven days at approximately the amount a Fund has valued the asset may be considered to be illiquid for purposes of the Fund’s illiquid investment limitations.
