The answers here are slightly misleading.

Any attack speed reduction will work off total attack speed.

However, keep in mind that frozen heart is the only item that provides a reduction to total AS.

Randuin's Omen, for instance, SLOWS attack speed by a %. There is a difference. (I.e., randuins subtracts 35% attack speed, the opposite of an item which grants 35% extra attack speed. Frozen heart actually reduces their total attack speed by 20%)
