LM could not reveal how much investors should expect in the first payment, although its update said that it intended to repay capital on a periodic basis.
The payment process is expected to take around two to three years, with payments likely to be made each quarter.
LM was founded in 1993 by expat New Zealander Peter Drake and claims to have assets worth more than A$3 billion under management.
The company was forced to go on the PR offensive last year after another Australian fund management firm, Trilogy Capital Group, attempted to take over two of its funds.
While Trilogy criticised LM's management of the First Mortgage Income Fund and said it lacked a clear strategy, the latter responded by calling Trilogy a "corporate fund raider" and accused it of spreading misinformation.
Trilogy successfully replaced LM as the responsible entity for one of the funds it had eyed up following a meeting held in Sydney in early November.
