A dependence of the value of the pion-nucleon sigma term on higher partial
waves is discussed. Two recent predictions of a high value of sigma term are
scrutinezed. It has been concluded that the main reason for obtaining high
values of the sigma term are input D waves that are not consistent with
analyticity.
