English to Italian Bus/Financial Investment / Securities Life Settlement Funds

Hi, there. I am translating a short text about Life Settlement Funds and there is this note: 'Investment levels and terms are subject to individual investment channels allowances and/or restrictions. For specific terms, please refer to your chosen channel.'
I was wondering, can I translate 'allowances' with 'concessioni' here or is there a better translation for that term in this context? My attempt reads: 'I livelli e i termini di investimento sono soggetti alle concessioni o restrizioni dei diversi canali di investimento. Per i termini specifici, vi rimandiamo al canale prescelto.'
Thanks so much for your help
