The Island's financial regulator has published its findings into a review of the accountancy profession.
The Financial Services Authority says it carried out 51 inspections to test customer risk assessments, which help prevent money laundering and terrorist financing.
It also looked at data from 196 accountancy firms, saying the review will help it update the Island's anti-money laundering handbook.
The FSA's Ashley Whyte thanked the companies which took part in the review.
