Abstract: Let $G$ be a discrete group, a commutative discrete cancellative semigroup or a locally compact abelian group. Let $UC(G)$ be the space of bounded, uniformly continuous, complex-valued functions on $G.$ With an Arens-type product, the conjugate $UC(G)^{*}$ becomes a Banach algebra. We prove, that unlike left ideals, finite-dimensional right ideals exist in $UC(G)^{*}$ if and only if $G$ is compact.
