Funds are often offered through several legal vehicles, such as onshore, offshore, feeder, parallel or tax-exempt versions, and each one files its own Form D. These 2 filings share this fund's name apart from such vehicle words or a series letter, which usually means they are versions of one fund. Grouped by AltMountain from the names on the filings alone, so the list may be incomplete or include a separate fund with a near-identical name; amounts are each vehicle's own filing and should not be added together, because a feeder's money can also be counted in its master fund.
