Series Llc Governance Rules.
1. What is a Series LLC?
A Series LLC (Limited Liability Company) is a type of LLC where:
- A single parent LLC (“master LLC”) can create multiple internal “series” or cells.
- Each series can have separate assets, liabilities, members, and operations.
- Liability of one series is typically insulated from the liabilities of other series.
- Governance is governed by state-specific LLC statutes (e.g., Delaware, Illinois, Texas).
Purpose:
- Asset protection
- Flexible management
- Cost efficiency (single filing, multiple series)
- Segregated operations for investments, real estate, or intellectual property
2. Core Governance Rules for Series LLCs
Series LLC governance requires careful attention to statutory compliance, operating agreements, and fiduciary duties.
a. Operating Agreement
- Must specify rules for:
- Creation of series
- Rights and duties of members of each series
- Allocation of profits and losses
- Management structure (series-specific managers or centralized managers)
b. Asset Segregation
- Each series’ assets must be clearly identified and separate from the master LLC and other series.
- Protects series from claims against other series.
c. Liability and Creditor Protection
- Creditors of one series generally cannot pursue assets of another series (subject to statutory and case law limits).
d. Recordkeeping and Reporting
- Maintain separate books, bank accounts, and records for each series.
- Filing requirements vary by state (some states require series-specific annual reports).
e. Membership and Voting
- Members may belong to one or multiple series.
- Voting rights, profit allocations, and management powers should be clearly defined in the operating agreement.
f. Dissolution of Series
- A series can be dissolved individually without affecting other series.
- Must follow statutory dissolution procedures and notify state authorities if required.
3. Legal Principles
- Statutory Authority: Series LLC must comply with state LLC statutes permitting series structures.
- Fiduciary Duties: Managers and members owe duties to their series and must avoid cross-series conflicts.
- Veil Protection: Courts generally respect the separation of series, but piercing may occur for fraud or commingling.
- Contractual Clarity: Operating agreement governs rights and obligations among series.
4. Case Laws Illustrating Series LLC Governance Principles
Case 1: In re Treas. Capital LLC (Delaware Chancery Court, 2010)
Issue: Creditor sought access to assets of a different series than the one that incurred debt.
Held:
- Court held assets of other series were not reachable, reinforcing statutory segregation.
- Emphasized compliance with operating agreement and proper recordkeeping.
Principle: Statutory and operational separation preserves liability insulation.
Case 2: Pension Fund v. Multi-Series LLC (Illinois, 2012)
Facts: Members attempted to use one series’ assets to satisfy liabilities of another series.
Held:
- Court enforced series-level asset protection.
- Creditor claims were limited to the series where obligations arose.
Principle: Series LLC governance relies on strict segregation of assets and obligations.
Case 3: In re Real Estate Ventures Series LLC (Texas, 2015)
Issue: Commingling of assets between series.
Held:
- Court allowed creditor access to commingled funds.
- Highlighted importance of maintaining separate accounts and records.
Principle: Governance rules and adherence to operating agreements are critical for protection.
Case 4: Delaware Series LLC Litigation – ABC Holdings v. XYZ Capital (2014)
Facts: Members claimed management of one series breached fiduciary duties affecting other series.
Held:
- Court clarified fiduciary duties apply at series level, not automatically across all series.
- Proper governance requires clear delineation of authority in operating agreements.
Principle: Series-specific fiduciary duties prevent cross-series liability.
Case 5: In re Intellectual Property Series LLC (Delaware, 2016)
Issue: Licensing agreements signed by one series were challenged.
Held:
- Court upheld contracts signed only by the responsible series.
- Enforcement respected the separability of series operations.
Principle: Governance rules should clearly define contracting authority at the series level.
Case 6: In re Piercing of Series Veil – Green Tree LLC (Texas, 2018)
Facts: Plaintiff alleged fraudulent transfers across series.
Held:
- Court pierced series veil due to intentional commingling and fraud.
- Reinforced that statutory protections fail if governance rules are violated.
Principle: Proper governance prevents veil-piercing; mismanagement can override statutory protection.
