The Auto-Callable Trigger PLUS do not guarantee the repayment of principal and do not provide for the regular payment of interest. The Auto-Callable Trigger PLUS are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income in exchange for the possibility of receiving an early redemption payment or the upside leverage feature and the limited protection against loss that applies only if the final index value is greater than or equal to the downside threshold level. The Auto-Callable Trigger PLUS are our senior debt securities. Any payments on the securities are fully and unconditionally guaranteed by Bank of America Corporation (“BAC”). The Auto-Callable Trigger PLUS are issued as part of BofA Finance LLC’s (“BofA Finance”) “Medium-Term Notes, Series A” program.
