Rule Naming Conventions in Investment Compliance: Best Practices from Top Asset Managers

Introduction

In an era where regulatory scrutiny is rising and compliance platforms are more complex than ever, the importance of investment compliance rules and their naming conventions is often underestimated. Yet, something as seemingly mundane as how you name a rule in Aladdin, Charles River, or AIM, etc. can have sweeping implications across audits, automation, team collaboration, and even client confidence.

At TillieStar, we work alongside asset managers, RIAs, and wealth platforms to implement scalable compliance systems that rely on thoughtful rule structure—and that starts with consistent, intuitive naming conventions. In this post, we’ll explore how leading firms are structuring their rule libraries, common pitfalls in naming logic, and how to apply industry best practices to avoid costly errors.

Why Rule Naming Matters in Investment Compliance

A well-named rule is more than just internal shorthand. It’s:

Searchable: Especially critical in large firms with 1,000+ rules across clients.
Auditable: Regulators like the U.S. Securities and Exchange Commission (SEC) expect clear documentation and traceability.
Collaborative: Clear names improve cross-functional understanding between compliance, IT, and investment teams.
Scalable: Supports system upgrades, platform migrations, and team changes without losing context.

According to the SEC’s Division of Investment Management, firms must maintain effective compliance programs, which includes the accurate implementation of policies and procedures into their systems. This includes how rules are defined, monitored, and documented.

Common Naming Challenges We See

From our work at TillieStar, here are some frequent issues that arise with naming compliance rules:

Duplicate rule IDs due to copy/paste across accounts
Abbreviations without a legend, causing confusion for new team members
Inconsistent formatting across systems (Aladdin vs Charles River vs Excel backup logs)
Poor client mapping, where naming doesn’t reflect investor-specific guidelines

Each of these can slow down audits, create system logic errors, or generate false positives during monitoring.

Anatomy of a Good Rule Name

While every firm has unique needs, effective rule names typically contain four elements:

Element	Example	Description
Client or Strategy Code	TS001	Identifies which client/account this applies to
Rule Category	LIQ, ESG, SECTOR	Shows the general type of restriction
Rule Type	MAX, PROHIBIT, LIMIT	Indicates the logic applied
Identifier/Notes	002, NO_TOBACCO, 20PCT_CASH	Further differentiates the rule

Example: TS001_LIQ_MAX_20PCT_CASH

This tells us: TillieStar Client 001 has a liquidity rule limiting cash exposure to 20%.

Real-World Rule Naming Examples (Anonymized)

1. Global Asset Manager (>$250B AUM) – Using Aladdin

Their naming convention includes:

ClientCode_Category_SubCategory_RuleType_SequenceNumber

Example: GAM01_ESG_FOSSIL_PROHIBIT_001

This structure allows for easy filtering, especially in Aladdin dashboards, and integrates well with their global ESG policy audits.

2. Boutique RIA – Using Sentinel

They opted for a simpler model:

ClientCode-RuleName-Category

Example: BRIA-NoTobacco-ESG

While more human-readable, the downside is inconsistent sorting and occasional duplicates—an issue we helped them streamline by introducing tagging and version control naming (v1, v2, etc.).

3. Multi-Strategy Fund – Using Charles River

StrategyCode_AssetClass_LimitType_CustomTag

Example: MSF_EQ_MAXEXP_TECH_10PCT

Their system had a heavy reliance on custom tags to meet client requests, which created bloat until we helped consolidate logic under shared templates and tighter naming governance.

TillieStar’s Rule Naming Best Practices

After years of experience managing investment compliance rules, our consultants at TillieStar recommend:

Create a Naming Schema Document
Define elements and maintain an internal guide shared across compliance and tech.
Use Controlled Vocabularies
Pick standard category terms (e.g., LIQ, CONCENTRATION, ESG) and enforce their use.
Leverage System Tags Where Possible
Platforms like CRD often allow metadata tagging in addition to names—use these!
Maintain a Rule Naming Legend
Especially important for firms with abbreviations (EQ, FI, HY, SRRI) to avoid ambiguity.
Version and Archive Obsolete Rules
Use suffixes like _V2, _ARCH, or timestamps to preserve rule history and avoid confusion.
Audit Quarterly
Include rule naming reviews as part of quarterly compliance reviews. Automated scripts can help flag outliers.

Regulatory Considerations & SEC Guidance

While the SEC doesn’t mandate specific naming conventions, Rule 206(4)-7 under the Investment Advisers Act of 1940 requires firms to adopt and implement written compliance policies and procedures. If your firm can’t clearly document or understand what a rule in your system means, you may be exposed to risk in an exam or enforcement action.

In the SEC’s 2024 Risk Alert on Examinations, examiners noted “ineffective implementation of restrictions” and “lack of documentation supporting monitoring logic” as recurring deficiencies.

Naming for ESG, Client-Directed, and Regulatory Rules

It’s especially important to separate rule types in naming:

Client-Directed: CL123_ESG_PROHIBIT_TOBACCO
Regulatory: 40ACT_CONCENTRATION_EQ_25PCT
Firm-Wide/Policy Rules: FIRM_LIQUIDITY_MINCASH_5PCT

Using these prefixes helps compliance teams—and regulators—understand which rules are optional vs. mandated.

What Happens When You Get It Wrong?

We recently worked with a mid-sized wealth manager whose compliance alerts skyrocketed by 45% quarter-over-quarter. The issue? A junior analyst reused a “No Energy Stocks” rule from another client without updating the name or modifying the sector exposure thresholds. As a result, trades triggered false positives—leading to client escalations and operational delays.

Post-incident, we helped the team implement a naming governance process and onboarded them to our Rule Library Clean-Up Framework, which included version control, de-duplication, and new rule templates.

Conclusion

Investment compliance rules are the backbone of a firm’s operational and regulatory integrity—but their naming is often overlooked. Whether you’re scaling your platform, onboarding new clients, or preparing for an audit, taking time to clean up your naming conventions can pay dividends in accuracy, efficiency, and trust.

At TillieStar, our team of investment compliance consultants brings deep expertise across systems like Aladdin, Sentinel, and Charles River. We don’t just name rules—we help you manage them at scale with clarity, consistency, and confidence.
