Nov 6 (Reuters) - U.S. health insurer Humana Inc
said on Wednesday that it expected a delay in the enrollment
period for the state-based health exchanges and was waiting to
hear from the government on how it will proceed after a rocky
start to this marketplace.
   ``Our assumption is that there will be an extension to the
open enrollment period,'' Chief Operating Officer Jim Murray said
during a call with investors to discuss quarterly results.
