The existence of an average cost optimal stationary policy in a countable state Markov decision chain is shown under assumptions weaker than those given by Sennott. This treatment is a modification of that given by Hu, and is related to conditions of Hordijk. An example is given for which the new axiom set holds whereas the axiom set of Sennott fails to hold.
