Abstract
It is shown that the celebrated result of Sparre Andersen for random walks and L\'evy processes has intriguing consequences when the last time of the process in , say , is added to the picture. In the case of no positive jumps this leads to six random times, all of which have the same distribution - the uniform distribution on . Surprisingly, this result does not appear in the literature, even though it is based on some classical observations concerning exchangeable increments.
