Although many Shadow NAV Administrator are available, what I found the best is Ascent's fund administration services. One important thing to note is, not all administrations provide you all Shadow NAV services, but Ascent will assure you of many solutions. NAV calculations, portfolio accounting, income and expense calculations, and keeping various financial records are the services they provide. Ascent will help with nearly all the legwork like accounting, charging of fees, statement, etc. You can also visit their website https://ascentfundservices.com for detailed clarification.
