FEBRUARY 2023 | J.P. Morgan Kronos+ SM Index Selected Risks Our affiliate, J.P. Morgan Securities LLC (“JPMS”), is the sponsor and calculation agent of the Index and may adjust the Index in a way that affects its level. The level of the Index will include the deduction of a fee of 0.95% per annum and, in some circumstances, a notional financing cost based on the Effective Federal Funds Rate. JPMorgan Chase & Co. is currently one of the companies that make up the Constituent. There are risks associated with the Index’s turn - of - month strategy. There are risks associated with the Index’s option expiry momentum strategy. There are risks associated with the Index’s mean reversion strategy. The Index’s strategies are applied during only a portion of each month. The Index may be adversely affected by an overlap between its turn - of - the - month strategy and its month - end mean reversion strategy. The Index may be uninvested in the Constituent. The Constituent of the Index may be replaced by a substitute index in certain extraordinary events. The notional cash return will be negatively affected if the underlying interest rate is negative. The Index, which was established on December 22, 2020, has a limited operating history and may perform in unanticipated ways. The Index comprises notional assets and liabilities. There is no actual portfolio of assets to which any person is entitled or in which any person has any ownership interest. The Index may not be successful or outperform any alternative strategy that may be employed of the Constituents. The Effective Federal Funds Rate is affected by a number of factors and may be volatile. The method pursuant to which the Effective Federal Funds Rate is determined may change, and any such change may adversely affect the value of notes linked to the Index. The risks identified above are not exhaustive .
