  Indices of acceptability are well suited to frame the axiomatic features of
many performance measures, associated to terminal random cash flows.We extend
this notion to classes of c\`adl\`ag processes modelling cash flows over a
fixed investment horizon.We provide a representation result for bounded paths.
We suggest an acceptability index based both on the static Average
Value-at-Risk functional and the running minimum of the paths, which eventually
represents a RAROC-type model. Some numerical comparisons clarify the magnitude
of performance evaluation for processes.
