We explicitly provide the transformation leading to sufficiency of 'optimal' allocations as characterized in DeGroot (Ann Inst Stat Math 18:13-28, 1966) and Stepniak (Ann Inst Stat Math 34:175-180, 1982). © Indian Statistical Institute 2012.Mahidol UniversityDecision SciencesMathematicsArticleSCOPUS10.1007/s13571-011-0029-5
