The dynamical analysis of American options has motivated the development ofrobust versions of the classical Snell envelopes. The cost of superhedging anAmerican option is characterized by the upper Snell envelope. The infimum ofthe arbitrage free prices is characterized by the lower Snell envelope. In thispaper we focus on the lower Snell envelope. We construct a regular version ofthis stochastic process. To this end, we apply results due to Dellacherie andLenglart on regularization of stochastic processes and T -Systems.
