If the CHF/USD spot and 3 month (91 days) forward rates are 1.

Forward premium or discount can be easily calculated as {(Forward rate - Spot rate) / Spot rate x 365/number of days]. In this case, it can be calculated as =((1.1652 - 1.1763) / 1.1763 ) * 365/91 = 3.785%, which is a discount as it is a negative number. It can also be interpreted as a discount as the forward price is lower than the spot price.
