Maitland will provide both firms with fund administration and company secretarial services.
Tufton Oceanic Assets and CIP Merchant Capital were supported by Maitland in the lead up to, during and post the initial public offering.
Both firms were listed on the London Stock Exchange (LSE) at the end of last year, meaning that two out of three Guernsey-domiciled funds were listed on the exchange in 2017.
Ian Horswell, senior business development manager at Maitland, said: “Administration of listed funds is a sweet spot of ours. Supporting two of the three Guernsey-domiciled firms that listed on the LSE last year has been very exciting for us.”
He added: “With our Guernsey presence established last summer, we are excited for what 2018 will hold for the business and look forward to a long lasting and successful relationship with both Tufton Oceanic Assets and CIP Merchant Capital.”
