A fractional CFO provides strategic financial leadership on a part-time or retainer basis, typically for a fixed number of days per month. Meanwhile, a full-time CFO is a permanent, salaried executive embedded in the business on a five-day-a-week basis. For most Cayman Islands investment managers and fund vehicles, the fractional model is the appropriate starting point: it delivers the senior financial oversight required by institutional investors and regulators at a cost that reflects the actual volume of work a lean offshore structure generates.
Time commitment and availability
A fractional CFO typically commits a defined number of hours or days per month under a retainer arrangement. This is commonly between four and fifteen days per month depending on the complexity of the entity. The scope covers financial statement review, board reporting, auditor liaison, regulatory filings, and strategic financial advice.
A full-time CFO is available five days a week and carries day-to-day ownership of the finance function, including managing any in-house accounting staff, real-time treasury oversight, and direct involvement in investment decisions with a financial dimension. For a Cayman manager with a lean operation and no in-house team, a full-time CFO would spend significant time on work that could be delegated to a bookkeeper at a fraction of the cost.
Cost comparison
A full-time CFO for a Cayman Islands investment manager, particularly one based in or regularly visiting Cayman, represents a significant fixed cost. In the US and the UK, total compensation packages for full-time CFOs in investment management firms typically range from US$250,000 to US$600,000 per year, including base salary, bonus, and benefits.
In the Cayman Islands, this cost is compounded by work permit fees, relocation costs, and the premium commanded by executives willing to relocate offshore. A fractional CFO retainer, by contrast, typically costs between US$3,000 and US$12,000 per month depending on scope, delivering savings of 60–80% against a full-time equivalent.
For an emerging manager, this cost differential is often the difference between a sustainable cost structure and an unsustainable one.
Depth of organisational integration
A full-time CFO sits on the leadership team, contributes to strategic decision-making on a day-to-day basis, and builds institutional knowledge of the business over time. They typically manage investor relations finance queries directly, lead capital raising financial workstreams, and act as a counterparty to the COO or legal counsel on an ongoing basis.
A fractional CFO provides equivalent expertise and seniority but is not embedded in the daily rhythm of the business. This is rarely a disadvantage for a Cayman fund manager whose primary financial complexity lies in quarterly reporting cycles, annual audits, and periodic fundraising, all of which can be scheduled and planned.
Regulatory and governance considerations
CIMA’s Corporate Governance Rule (2023) requires the governing body of a regulated entity to ensure senior management possesses appropriate qualifications and experience. Both a fractional CFO and a full-time CFO can satisfy this requirement, provided the arrangement is properly documented and the individual’s responsibilities are clearly defined in their engagement or employment terms.
For CIMA-licensed investment managers operating under the Securities Investment Business Act (SIBA), the key question is whether the CFO, whether fractional or full-time, is identified in the entity’s regulatory filings and governance documentation where required, and whether their credentials satisfy CIMA’s fit and proper standards.
When to transition from fractional to full-time
The transition typically becomes appropriate when the fund manager’s operational complexity grows to a point where the fractional CFO’s available days are consistently insufficient. Examples include: when assets under management exceed US$500 million; when the number of fund vehicles or co-investment structures multiplies; when a significant institutional investor requires dedicated CFO-level engagement; or when the manager is preparing for a merger or IPO.
Until that threshold is reached, most Cayman fund managers are better served financially and operationally by the fractional model.
The right choice between a fractional and full-time CFO depends on where the manager is in its lifecycle and what its investors and regulators actually require.

FAQs
A fractional CFO provides strategic financial leadership on a part-time or retainer basis, typically for a fixed number of days per month. Meanwhile, a full-time CFO is a permanent, salaried executive embedded in the business on a five-day-a-week basis. For most Cayman Islands investment managers and fund vehicles, the fractional model is the appropriate starting point: it delivers the senior financial oversight required by institutional investors and regulators at a cost that reflects the actual volume of work a lean offshore structure generates.
This depends on the specific filing and the terms of the fractional CFO’s engagement. For CIMA-licensed entities, certain regulatory filings require sign-off from a named approved person on the licence. If the fractional CFO is named on the licence in an appropriate capacity, they can sign off on relevant filings. The arrangement must be clearly documented in the engagement agreement, and CIMA must be notified of any changes to relevant senior officers or notified individuals in the prescribed manner.
Economic substance requirements under the International Tax Co-operation (Economic Substance) Act (as revised) apply to certain Cayman entities undertaking relevant activities. The substance test considers whether the entity is directed and managed in the Cayman Islands, which is a board-level and governance question rather than a CFO-specific one. A fractional CFO engagement does not, of itself, affect substance compliance, though the CFO’s physical location and involvement in key management decisions may be a relevant factor in the substance analysis.
A fractional CFO is typically engaged under a professional services agreement, not an employment contract. That agreement defines the scope of work, monthly retainer fee, reporting lines, confidentiality obligations and termination provisions. For regulated entities, the agreement should also address CIMA notification requirements if the CFO is to be a named approved person. The engagement is usually reviewed annually and can be scaled up or down as the entity’s needs change.
