Comb Copy and NEC (Not Elsewhere Classified) means that a particular brand or combination of brands did not fit into any category within a specific class, and is therefore put into the Comb Copy and NEC for that class.

Example: Category F611 is for Regular Beer & Ale, Category F612 is for Light & Low Alcohol Beer & Ale. If both a regular and a light beer are advertised together, then the brand and ad spending will go in F619 Beer & Ale: Comb Copy and NEC.
