Positive Solutions is confident partners who resigned last week over an eleventh-hour directive that will see exiting advisers charged a leavers' fee will stay with the company.
At least 18 partners submitted provisional resignations on Thursday hours after being made aware of the rule, which came into effect from midnight that evening.
The directive stated advisers leaving the Aegon-owned national IFA after 1 April would be invoiced for their share of the company's regulatory costs up to 31 March the following year.
Partners were told the fee would include, but may not be limited to, their share of FSA and FSCS fees as well as professional indemnity insurance costs, all of which Positive Solutions incurs in advance.
It said the directive protected those advisers staying with the company. Partners had earlier been told charges were increasing to reflect the rising regulatory costs.
Chief executive Jim Reeve says he is confident partners who quit in the wake of the announcement will change their minds.
"We are not trying to penalise partners, lock them in or charge them costs they are not due," he told IFAonline.
"We will engage with partners to try to understand why they have resigned. My hope is we will retain those individuals angered by the communication. I am confident I can change their minds.
"But this is a major message for the marketplace: the cost of providing the security Positive Solutions provides is rising."
Reeve says Positive Solutions is thrashing out exactly how a leavers' fee will be calculated before communicating that to partners this week.
Included will be the proportion of investment business written by an adviser, as this is used by the FSA to calculate FSCS levies.
In the last two years, Positive Solutions has paid £1.9m toward two FSCS interim levies to cover the cost of compensation claims against failed investment companies, including Keydata.
It says on both occasions it absorbed the charge with no financial impact on partners, but this is no longer possible.
Meanwhile, Reeve says the company was not trying to "be sneaky" by including the directive in a mailshot to parners just hours before it was due to come into effect.
He says the company had earlier finished a series of its Synergy events where it sought the views of partners on the charges increase.
"We did not think the leavers' fee rule would cause the upset it has," he says. "We learn from these things."
