Aon
Editor pickMandate-level oversight that connects operational manager monitoring to committee-ready investment reporting.
Best for: Fits when institutions delegate oversight but require committee-grade governance, reporting, and manager monitoring.

Comparison Table
Northern Trust
enterprise_vendorNorthern Trust offers outsourced chief investment officer services and delegated portfolio management for institutions.
Mandate-driven delegated execution with governance alignment across discretionary and non-discretionary workflows.
Northern Trust fits institutions that need outsourced investment execution wrapped in a decision-control framework rather than only portfolio construction guidance. Delegated investment management coverage supports discretionary investment management and non-discretionary advisory operating models, which matters when responsibility is split between an investment committee and the service provider. The delivery includes portfolio operations routines such as rebalancing mechanics and cash-flow handling, plus ongoing monitoring inputs that feed manager selection and review processes.
A key tradeoff is that delegated authority clarity and internal governance discipline must be strong, because Northern Trust execution is constrained by the provided mandate, IPS expectations, and agreed rebalancing boundaries. A common usage situation is a large institutional client consolidating multiple manager strategies into a monitored multi-manager portfolio while keeping an investment committee workflow for benchmark selection, policy review, and attribution-focused reporting.
- +Strong discretionary and non-discretionary operating-model support
- +Execution focus on rebalancing and cash-flow management routines
- +Structured reporting inputs for performance, risk, and manager reviews
- +Clear governance alignment between delegation and investment committee cycles
- –Mandate-bound implementation can slow changes without governance alignment
- –Integration depth with internal tooling depends heavily on client processes
- –Operational documentation load is higher than for lighter advisory models
- –Manager review workflow may require more client participation than expected

Best for: Fits when large institutions need delegated authority execution with investment committee governance control.
Aon
enterprise_vendorAon offers delegated investment management, fiduciary governance, and risk-aware portfolio implementation.
Mandate-level oversight that connects operational manager monitoring to committee-ready investment reporting.
Aon fits institutions that already have a defined investment committee process and want a delegated provider to execute manager oversight and monitoring against that framework. The service is geared toward discretionary and non-discretionary advisory engagements, with emphasis on strategic allocation targets, mandate execution controls, and periodic performance review packaging. Aon’s delivery posture is strongest when the institution needs consistent manager review cycles and operational due diligence workflows that connect to the investment reporting cadence.
A clear tradeoff is reliance on a defined delegation model and decision boundaries, since governance outcomes depend on how authority is documented and how exceptions are handled. Aon is a strong choice when internal teams need reduced operational load for manager monitoring and reporting production, while still maintaining oversight over mandate definitions and risk monitoring expectations.
- +Strong investment committee reporting cadence for delegated mandates
- +Operational due diligence workflows tied to ongoing manager review
- +Mandate-based monitoring supports rebalancing expectations
- +Clear governance handoffs for discretionary decision boundaries
- –Delegation success depends on disciplined authority and exception governance
- –Technology integration depth can lag when proprietary data feeds are required
- –Customization may require more lead time than lighter advisory models
- –ESG coverage needs alignment with the institution’s reporting format

Best for: Fits when institutions delegate oversight but require committee-grade governance, reporting, and manager monitoring.
State Street
enterprise_vendorState Street provides delegated investment management, OCIO services, and institutional portfolio solutions.
Mandate translation from investment policy statement into executable rebalancing processes with recurring committee reporting.
State Street is a strong choice for institutions seeking delegated investment management delivery that couples asset servicing scale with investment operations for separately managed accounts and pooled investment vehicles. Implementation tends to focus on translating the investment policy statement into a delegated authority matrix, then operationalizing the resulting strategic asset allocation and rebalancing mandate within agreed controls. Where internal governance is mature, the provider can align manager selection and manager review workflows to the institution’s due diligence and reporting expectations.
A clear tradeoff is that deeper governance alignment and reporting cadence often require more upfront mandate definition and a tighter operating rhythm than lighter-weight models. State Street fits best when investment committee deliverables are recurring and audit-oriented, and when the organization needs consistent investment reporting for fiduciary stakeholders across multiple portfolios.
- +Operational execution tied to custody-scale processes
- +Clear mapping from investment policy statement to mandates
- +Consistent investment reporting for investment committee workflows
- +Strong support for multi-portfolio manager oversight
- –Requires disciplined mandate and governance documentation upfront
- –Less suitable for highly bespoke reporting formats without planning
- –Integration timelines can be longer for fragmented internal systems
- –Workflow fit depends on internal approval and exception routing

How to Choose the Right Delegated Investment
What separates delegated investment options is how consistently they convert your intent into automated actions, then how much proof you get afterward. Look hardest at criteria like audit log coverage and access controls, plus reporting automation that matches the way the portfolio is delegated.
Delegation authorization workflows
Why it matters
Delegation authorization workflows matter because delegated investment fails when permissions and approvals lag behind real decisions. You want the tool to track who authorized each instruction and keep it tied to the delegated scope.
How to check
During a demo, ask the operator to place a sample delegated instruction and show the approval or authorization trail. Verify you can view the delegation scope and the actor identity on that instruction record afterward.
Audit log coverage for changes
Why it matters
Audit log coverage for changes matters when you delegate investment and later need to explain what changed, when, and why. Strong logs reduce ambiguity during reviews and investigations.
How to check
Ask for a change log example: e.g., update a mandate parameter or re-map an instruction field. Confirm you can filter by user, time, and record, and that both the old and new values appear.
Reporting automation and exports
Why it matters
Reporting automation and exports matter because delegated investment work depends on timely evidence without manual stitching. You want scheduled outputs that reflect delegated activity, not just raw positions.
How to check
Request a sample scheduled report bundle for the last month and a CSV/XLS export from the UI. Check whether delegated instructions, fees, and outcomes are linked to the same reporting period.
Data provisioning and field mapping
Why it matters
Data provisioning and field mapping matter because delegated investment systems must reconcile instructions, holdings, and benchmarks into one coherent workflow. Mis-mapped fields cause silent errors that look correct in screenshots.
How to check
Ask the demo to ingest a sample holdings file and a sample instruction. Then verify the tool shows a clear mapping for key fields (accounts, instruments, dates) and flags mismatches before execution.
RBAC and role separation
Why it matters
RBAC and role separation matter because delegation touches sensitive instructions and outcomes. If roles are too broad, delegated investment governance becomes guesswork.
How to check
During the demo, request at least two roles (e.g., delegate user and viewer) and confirm what each can see and do. Verify read-only roles can’t alter delegated instruction parameters.
Instruction reconciliation and lifecycle
Why it matters
Instruction reconciliation and lifecycle matter because delegated investment is judged by execution and follow-through. You need statuses that show submitted, accepted, executed, and exception handling in a single timeline.
How to check
Ask the operator to run a test instruction that triggers an exception (wrong date or missing reference) and show the lifecycle timeline. Confirm the system stores the reason code and the remediation path you can take next.
Red flags
- Role separation that still allows viewers to edit delegated instructions
- Change history that shows timestamps but not what values changed
- Reports that separate delegated actions from outcomes without a shared period or reference
Fit by situation
- If your team delegates instructions through multiple internal roles, prioritize Delegation authorization workflows.
- If you expect later reviews of instruction intent versus execution, prioritize Audit log coverage for changes.
- If you need repeatable evidence for delegated outcomes, prioritize Reporting automation and exports.
