The investment objective of the ETC Securities is to allow an investor to gain an economic exposure to an Underlying Metal (and, in the case of FX Hedged ETC Securities, also offset any loss or gain in the value of the ETC Security attributable to FX movements). If an Underlying Metal is materially impacted by an unexpected event (or, in the case of FX Hedged ETC Securities, the FX hedging is materially impacted), then it may not be possible to achieve the investment objective of the ETC Securities based on the original terms and conditions of the ETC Securities and there may be a need to make certain discretionary determinations in order to preserve the original economic objective and rationale of the ETC Securities.
