PE Glossary for Law Firm Partners

Private equity has its own dense, deliberate language and jargon. Some Firm Managers (General Partners) use this jargon out of habit but others use it intentionally in the attempt to manipulate and put people on the other side of the table at a disadvantage. This glossary covers most of the terms you are likely to encounter in plain English. Written for lawyers evaluating or already inside a PE deal so they will know exactly what is being discussed and what they should ask, when these terms are used.

This is education, not legal advice

We can't emphasize enough that you MUST retain independent counsel - someone who represents only you, not the MSO, before signing anything containing these terms. Many of these structures look favorable on the surface and contain serious embedded risks that only surface later. If you don't know a specialist in this area, we have a network of MSO lawyers to choose from. One other note: If the MSO hasn't encouraged you to retain the best MSO counsel, that's a definite red flag!

Add Backs
Adjustments made to EBITDA to present a clearer or more favorable picture of profitability. Some are legitimate, such as one time expenses or unusual owner perks. Others are aggressive. This is one of the first places valuation gets negotiated and one of the first places it gets challenged during diligence.

Add On
A firm acquired after the initial platform investment. Add ons typically receive less customization and more standardization. If you are not early, you are usually integrating into an existing system rather than shaping it.

Alignment, Internal
PE wants to confirm that all equity partners and key decision makers are aligned on doing a deal. One resentful or skeptical partner can act as a “poison pill,” slowing integration, resisting change, or undermining execution. This can reduce valuation or kill a deal entirely.

Alignment of Interests
A commonly used phrase suggesting that everyone benefits from the same outcomes. In practice, it often means the sponsor has structured incentives so that your effort, your clients, and your rollover equity support their return model. True alignment requires careful structuring, not just language.

Arbitrage
The strategy of acquiring firms at lower multiples and combining them into a platform that can later be sold at a higher multiple. You may see a sale. They see a building block.

Auction Process
A competitive sale with multiple bidders. It can increase valuation but can also lead to rushed decisions, superficial comparisons, and selection of a partner based on price rather than structure. This is where advisors and attorneys earn their keep.

AUM
Assets Under Management. Large AUM suggests financial strength, but also means you may be a small piece of a much larger portfolio with less individual attention.

Bad Leaver
A partner who exits under unfavorable conditions. Consequences can include forfeiture of equity, loss of upside, forced repurchase at a discount, or clawbacks. The definition of “bad” matters enormously.

Board Control
Where real authority sits after closing. Titles are cosmetic. Board rights determine decisions on budgets, hiring, acquisitions, compensation, and exit.

Bolt On
A smaller acquisition designed to strengthen the platform. Often implies faster integration and less autonomy than the platform firm.

Burn Off
The gradual reduction of clawback or repayment obligations over time. The structure of the burn off determines whether retention incentives are reasonable or punitive.

Buy and Build
The core PE strategy of acquiring a platform and then growing through acquisitions. Law firms should understand whether they are the centerpiece or simply part of a roll-up strategy.

Capital Deployment
How and when capital is actually invested into the firm. Firms often hear large numbers promised. The real issue is who controls deployment and whether funding can be delayed, reduced, or denied.

Capital Deployment Conditions
The requirements that must be met before capital is released. These may include performance targets, budget approvals, leadership retention, or lender consent. Promised capital is only as real as these conditions.

Clawback
A provision requiring repayment of money already received if certain events occur. Often functions as an economic non-compete. If structured aggressively, it can create significant personal financial risk.

Concentrated Leadership
PE evaluates whether leadership and decision making are concentrated in a small, effective group or diffused across too many voices. Highly concentrated, aligned leadership is viewed as a positive. Fragmented or political leadership is viewed as risk.

Cultural Flexibility
The firm’s willingness to evolve. PE is assessing whether partners are open to changes in compensation, staffing models, technology, marketing, and governance. Resistance reduces valuation and slows deals.

Earn Out
Deferred compensation tied to performance. If someone else controls the variables that determine performance, they influence whether you get paid.

EBITDA
The core valuation metric. In practice, it is a negotiated number shaped by adjustments, assumptions, and diligence.

Equity Rollover
Reinvesting part of your proceeds into the new structure. This creates upside participation but also ties your financial future to the success of the platform.

Execution Risk
PE evaluates whether the firm can actually implement the growth plan. A firm may look strong on paper but still be viewed as risky if leadership, systems, or culture cannot support change.

Financial Modeling
The projections and assumptions used to forecast growth, profitability, and eventual exit value. These models often support valuation and the narrative of the deal. They are not guarantees. Law firms should understand the assumptions driving the model, including growth rates, margins, hiring plans, and exit multiples, and evaluate whether they are realistic. We recommend hiring an analyst with experience in financial modeling to do a "review only" (more cost efficient than having them build completely new models) of the models provided by the MSO.

Growth Levers or just Levers
The specific ways PE believes the firm can grow. This may include geographic expansion, practice area expansion, increased marketing, higher case values, improved realization, or acquisitions. If the levers are unclear or unrealistic, valuation suffers.

Internal Resistance Risk
The likelihood that partners or key personnel will resist operational changes. Even highly profitable firms can be discounted if PE believes internal friction will slow execution.

Key Man Risk
Risk tied to one or two rainmakers controlling a large portion of revenue. This often leads to clawbacks, retention incentives, or structural protections for the investor.

Leverage (Operational, not Debt)
PE evaluates how scalable the firm is. Can revenue grow faster than costs, or does every dollar of growth require proportional hiring and expense? Firms with strong leverage receive higher valuations.

Market Terms
A phrase used to suggest that the structure, economics, or provisions being offered are “standard” or “typical.” This can be helpful context, but it is often used to discourage negotiation. The reality is that terms vary widely based on timing, competition, firm quality, and leverage. “Market” is not fixed. It is situational.

Master MSO
The top level entity where economics and exit value are aggregated. Even if your firm has its own MSO, the real value is often created at this level.

Mothership
The parent entity controlling economics, governance, and exit. Firms often underestimate how much control sits here.

Openness to Adoption
A critical underwriting factor. PE evaluates whether the firm is willing to adopt new systems, technology, marketing strategies, reporting standards, and management structures. Firms that resist adoption are viewed as difficult to scale.

Phantom Stock
A contractual right to share in value without actual ownership. Its value depends entirely on the plan structure and payout terms.

PIU (Profits Interest Unit)
An equity-like interest that participates in future growth. Often attractive, but subject to vesting, dilution, and structural limitations that affect real value.

Platform Firm
The anchor investment. Platform firms typically have more influence, better economics, and greater control than later acquisitions.

Professionalization
PE’s process of installing systems, reporting, management structure, and operational discipline. This is often necessary for growth, but can be disruptive to firms used to autonomy.

RSA (Restricted Stock Award)
Actual equity subject to vesting and repurchase rights. The restrictions determine its true value.

Second Bite of the Apple or just Second Bite
The future payout when the platform is sold. Often the most compelling part of the deal, and the most misunderstood.

Strategic Acceleration
The idea that capital, infrastructure, and expertise will allow the firm to grow faster than it could on its own. This is one of the central promises in PE-backed MSO deals. It can be real, but it depends entirely on execution, leadership alignment, and whether the promised resources are actually deployed.

Synergy
The expected benefit from combining businesses, such as cost savings, increased revenue, shared infrastructure, or improved efficiency. Synergies are frequently highlighted in deal discussions and projections. Some are real. Some are optimistic. The key question is who bears the cost and will disruption be required to achieve them

Synthetic Non Compete
Economic structures that discourage departure without explicitly restricting it. Clawbacks, forfeiture, and lost upside create strong incentives to stay.

Upside Participation
Your share of future value creation. Its real value depends on structure, dilution, and where it sits in the capital stack.

Value Creation Plan
PE’s roadmap for growth. This includes hiring, marketing, acquisitions, pricing strategy, and operational improvements. A vague plan is a warning sign.

Withdrawal Rights
The ability to exit the MSO relationship. Often heavily restricted. Firms should understand exactly how and when they can leave and at what cost.

Withdrawal Triggers
Specific events that allow or restrict exit. Poorly defined triggers can effectively lock firms into long term arrangements.
