Do the nutritional facts on chewing gum assume you swallow the gum?

Had this thought while enjoying a piece of gum.

The process of mastication combined with the secretion of saliva do a fine job of extracting most of the carbohydrates and other soluble compounds that exist in chewing gum. When you swallow, the compounds solubilized in one's saliva go through the same digestive/absorptive processes like any other foodstuff. When all of this is "extracted" one is left with the flavorless, goey lump we associate with gum that has been chewed well beyond flavor. It is likely that this mass is somewhat undigestable or unusable by the body, contributing nothing to caloric content.
