Cambridge Associates and Groton School Custom Case Solution & Analysis

Evidence Brief: Cambridge Associates and Groton School

Financial Metrics

Endowment Value: The Groton School endowment stood at approximately 380 million dollars at the time of the case analysis (Exhibit 1).
Spending Rate: The school maintains a 5 percent annual draw to support operations, necessitating a nominal return of at least 7 to 8 percent to account for inflation (Paragraph 4).
Asset Allocation: 33 percent in global equities, 22 percent in private equity, 15 percent in hedge funds, and the remainder in real assets and fixed income (Exhibit 3).
Performance Lag: The endowment underperformed its policy benchmark by 120 basis points over the trailing three-year period (Exhibit 2).
Fee Structure: Cambridge Associates (CA) charges a flat advisory fee plus performance-based incentives for specific private mandates, totaling roughly 40 to 60 basis points across the portfolio (Paragraph 12).

Operational Facts

Relationship Longevity: CA has served as the primary investment advisor for Groton for over 30 years (Paragraph 2).
Investment Committee (IC) Structure: Composed of 9 volunteer members, primarily alumni with backgrounds in finance and law (Paragraph 6).
Decision Cycle: The IC meets quarterly. Decisions on manager selection or asset allocation changes require a majority vote, often resulting in a 3 to 6 month lag from recommendation to execution (Paragraph 8).
CA Service Model: Traditionally non-discretionary advisory. CA provides research and recommendations; the IC retains all decision-making authority (Paragraph 10).

Stakeholder Positions

James Higgins (IC Chair): Recognizes the increasing complexity of private markets but values the fiduciary oversight provided by the volunteer committee.
Cambridge Associates Consultants: Advocating for a shift toward a discretionary (OCIO) model to improve execution speed and access to oversubscribed managers.
Groton Board of Trustees: Concerned with long-term institutional stability and the ability of the endowment to fund scholarships and faculty salaries.

Information Gaps

Specific Manager Fees: The case does not detail the underlying management and performance fees paid to external hedge fund and private equity managers.
Net-of-Fee Benchmarking: Detailed comparisons between the advisory model and CA discretionary track record are not fully disclosed for the specific mid-market endowment segment.

Strategic Analysis

Core Strategic Question

Can the Groton School continue to achieve its required returns through a non-discretionary volunteer-led model, or must it cede control to an Outsourced Chief Investment Officer (OCIO) to remain competitive in private markets?

Structural Analysis

The investment management value chain has shifted. Alpha is increasingly found in illiquid, capacity-constrained private markets where speed of execution and deep network access are mandatory. The traditional advisory model creates a structural delay. By the time the Groton IC approves a recommendation at a quarterly meeting, top-tier venture capital or buyout funds have often closed their subscription windows. The principal-agent friction between CA (the advisor) and the IC (the decision-maker) results in a portfolio that is perpetually behind the market curve.

Strategic Options

Option 1: Transition to Full Discretionary (OCIO) Model

Rationale: Eliminates the execution gap. CA gains the authority to move capital into high-conviction managers immediately.
Trade-offs: Higher direct fees to CA; loss of IC influence over specific manager selection; increased institutional reliance on a single partner.
Resource Requirements: Legal overhaul of the investment management agreement and a redefined role for the IC focusing on policy rather than selection.

Option 2: Enhanced Advisory with Delegated Authority

Rationale: A middle path where the IC sets tight parameters but allows CA to execute within those bounds for liquid assets.
Trade-offs: Fails to solve the access problem for private equity where the most significant underperformance occurs.
Resource Requirements: Increased reporting frequency and more granular policy guidelines.

Option 3: Internalization and Passive Shift

Rationale: Move 70 percent of the portfolio to low-cost indices and manage a small sleeve of direct investments internally.
Trade-offs: Forgoes the potential for alpha in private markets; necessitates hiring internal staff which the school budget may not support.
Resource Requirements: Significant investment in internal tracking software and compliance.

Preliminary Recommendation

Groton should adopt the full discretionary (OCIO) model. The complexity of the 22 percent private equity allocation and 15 percent hedge fund allocation requires professional, full-time management that a volunteer committee cannot provide. The 120 basis point underperformance exceeds the projected fee increase associated with the OCIO model.

Implementation Roadmap

Critical Path

Month 1: Governance Redefinition. Rewrite the Investment Office Charter. Shift the IC role from manager selection to asset allocation strategy and risk oversight.
Month 2: Contractual Transition. Negotiate the new discretionary agreement with CA. Define explicit performance hurdles and termination clauses.
Month 3: Portfolio Rebalancing. CA executes a sweep of the liquid portfolio to align with the new strategic asset allocation.
Month 4-6: Private Market Catch-up. CA initiates capital calls for oversubscribed funds that were previously inaccessible under the advisory model.

Key Constraints

IC Resistance: Several long-standing members view manager selection as their primary contribution. Managing this ego-driven friction is the chief operational hurdle.
Fee Transparency: The school must ensure that the move to OCIO does not lead to an opaque layering of fees that erodes the expected alpha.

Risk-Adjusted Implementation

The transition will occur in phases. Liquid assets (equities and fixed income) will move to discretionary management in the first 90 days. Private equity and hedge fund mandates will remain under a consultative-approval model for 12 months to allow the IC to gain confidence in the CA discretionary team. This phased approach mitigates the risk of a total loss of control while addressing the immediate need for execution speed in the liquid portfolio.

Executive Review and BLUF

BLUF

Groton must transition to an Outsourced CIO model immediately. The current volunteer-led governance structure is an operational bottleneck that has resulted in a 120 basis point performance lag. In a market where 37 percent of the portfolio is in alternative assets, the speed of execution is the primary driver of alpha. The Investment Committee should pivot to high-level policy oversight and delegate manager selection to Cambridge Associates. Maintaining the status quo is a failure of fiduciary duty that threatens the 5 percent annual spending requirement.

Dangerous Assumption

The analysis assumes that Cambridge Associates possesses a superior ability to select winning managers when acting with discretion compared to their advisory track record. There is a risk that the previous underperformance was not due to IC delays, but rather to the quality of CA research itself.

Unaddressed Risks

Institutional Capture: By moving to an OCIO model, Groton becomes structurally dependent on CA. Reversing this decision in 5 years would be prohibitively expensive and operationally disruptive.
Concentration Risk: CA may place Groton into the same proprietary commingled funds as their other OCIO clients, reducing the unique diversification benefits of the Groton endowment.

Unconsidered Alternative

The team did not fully evaluate joining a multi-institutional investment office (e.g., a consortium of similar prep schools). This could provide the scale and access of an OCIO model while maintaining more specialized focus on the needs of educational institutions at a lower cost than a commercial firm like CA.
