Abstract: Every bounded regular Borel measure on noncompact LCA groups is a sum of an absolutely continuous measure and a measure with natural spectrum. The set of bounded regular Borel measures with natural spectrum on a nondiscrete LCA group $G$ whose Fourier-Stieltjes transforms vanish at infinity is closed under addition if and only if $G$ is compact.
