More precisely, we characterize the optimal strategy as the integrand appearing in the GaltchoukKunitaWatanabe decomposition of the benchmarked contingent claim under partial information and provide its description in terms of the integrand in the classical GaltchoukKunitaWatanabe decomposition under full information via dual predictable projections. Finally we show how these results can be applied to unit-linked life insurance contractsEn: Insurance : mathematics and economics. - Oxford : Elsevier, 1990- = ISSN 0167-6687. - 03/03/2014 Volumen 55 Número 1 - marzo 2014 I.
