How the Murk Score Works
The Murk Score is a transparency index, not a quality rating. It measures how much useful financial and operational data a franchisor actually discloses in their Franchise Disclosure Document (FDD). Lower is better.
Proprietary methodology developed from analysis of thousands of FDDs.
What Does the Score Mean?
0–1
CLEAR
Comprehensive disclosure, no red flags
2–39
MODERATE
Some transparency gaps detected
40–64
ELEVATED
Significant omissions or concerns
65–100
OPAQUE
Major deficiencies or solvency warnings
What the Murk Score Evaluates
32 binary checks across 5 pillars. Every check is a verifiable fact extracted directly from the FDD: no interpretation, no subjective assessments.
Disclosure Completeness
“Did the franchisor tell you how much franchisees actually make?”
Does the FDD provide the financial data a reasonable investor would need? Evaluates the presence, depth, and quality of financial performance representations and audited financial statements.
- •Whether the franchisor provides any financial performance data at all
- •The depth and quality of earnings representations — medians, expenses, sample sizes
- •Whether financial statements are independently audited by a CPA
System Trajectory
“Is the system growing — or are franchisees leaving?”
Is the franchise system growing or shrinking? Analyzes multi-year outlet data and revenue trends to detect unit decline, franchisee departure patterns, and concerning growth signals.
- •Multi-year unit growth or decline trends across the system
- •Franchisee departure patterns and their severity
- •Revenue trajectory and growth sustainability signals
- •Franchise system age and operational track record
Franchisor Solvency
“Can the franchisor stay in business long enough to support you?”
Can the franchisor meet its obligations? Examines audit opinions, financial health indicators, balance sheet equity, and bankruptcy disclosures across the corporate family.
- •Audit opinion quality and going concern warnings from independent CPAs
- •Balance sheet health and solvency indicators
- •Bankruptcy history across the franchisor and affiliated entities
Internal Consistency
“Do the numbers in the FDD actually add up?”
Do the numbers in the FDD agree with each other? Cross-checks arithmetic across financial statements and outlet tables, and flags statistically implausible patterns.
- •Balance sheet arithmetic verification — do assets equal liabilities plus equity?
- •Outlet table reconciliation across multiple reporting years
- •Statistical plausibility of reported numbers and exit data
Litigation
“Are franchisees suing — and how often?”
What does the FDD disclose about lawsuits, government actions, and officer conduct? Every check triggers on concrete facts the franchisor disclosed in their own government-filed document.
- •Government enforcement actions from state AGs or the FTC
- •Franchisee-initiated lawsuit volume and patterns
- •Class actions and officer criminal history disclosures
How a Murk Score Is Computed
- 01.
FDD is uploaded and parsed
The system ingests the full Franchise Disclosure Document and extracts structured data from all 23 required items.
- 02.
Each of the 32 checks is evaluated
Every check produces a binary result: triggered or not triggered. There are no sliding scales, only verifiable facts from the document.
- 03.
Score is computed
Triggered checks contribute to the score based on their materiality. Checks that affect your ability to evaluate the investment carry more weight than minor documentation gaps. The score is capped at 100.
- 04.
Transparency label is assigned
The final score maps to a label: CLEAR, MODERATE, ELEVATED, or OPAQUE, each representing a tier of disclosure quality.
Why Trust the Murk Score?
Verifiable, Not Subjective
Every check is a binary fact extracted directly from the FDD. Either the document contains the data or it does not. There are no opinion-based ratings, no subjective assessments, no “expert judgment” scores.
Deterministic and Reproducible
The same FDD run through the Murk Score system will always produce the same result. The methodology is rules-based, not dependent on who runs the analysis or when.
Sourced from Public Records
All data comes from Franchise Disclosure Documents filed with state regulators. FDDs are public records available through 13+ franchise registration states. Every finding is traceable to a specific FDD item number.
Not a Replacement for Legal Counsel
