How to Structure Indirect Rates for a PE Acquisition

Indirect rates are the mechanism by which a GovCon company allocates its non-direct costs — fringe benefits, facilities, overhead, and G&A — to its contract work. For commercial companies, overhead allocation is primarily an accounting exercise. For GovCon companies, it is a contractual relationship with the federal government, a compliance obligation, and — in a transaction — one of the most scrutinized elements of the financial due diligence process.

Most GovCon founders know their rates and know they need to manage them. Fewer have stress-tested whether the structure behind those rates — the pool definitions, the allocation bases, the documentation, the consistency of application — would hold up to the interrogation of a sophisticated PE buyer's quality of earnings team. The gap between "our rates are fine" and "our rate structure is defensible in diligence" is where most GovCon M&A re-trades originate.

The anatomy of a GovCon indirect rate structure

A standard GovCon indirect rate structure consists of three pools, each allocated to contracts using a base that reflects how those costs are actually consumed.

Fringe benefits pool captures employer-paid benefits — payroll taxes, health insurance, retirement contributions, PTO accruals, and similar costs. The standard allocation base for fringe is direct labor dollars or total labor dollars, depending on whether the company applies fringe to all labor or only to direct labor. The pool rate is expressed as a percentage of the base: fringe benefits divided by direct labor dollars equals the fringe rate.

Overhead pool captures indirect costs that support the direct performance of contracts — facilities, direct-charging employee support costs, program management overhead, and similar items. The allocation base is typically direct labor dollars or direct labor hours. Overhead is distinct from G&A in that it supports direct performance specifically; G&A supports the enterprise as a whole.

G&A pool captures general and administrative costs — executive compensation, business development, accounting, legal, HR, and enterprise-level costs that cannot be allocated to a specific project or division. The standard allocation base for G&A is total cost input (direct labor, fringe, and overhead applied to contracts) or cost of sales. G&A is the final pool applied and represents the broadest claim on the contract revenue base.

Where structures break in diligence

A rate structure that has worked operationally for years can have deficiencies that only become visible under quality of earnings (QoE) scrutiny. The most common failure patterns:

Undocumented pool definitions. The pools exist and the rates are applied, but the written definitions of what belongs in each pool — and why — don't exist or haven't been updated to reflect the current business. When the QoE team asks for the cost accounting disclosure statement or the pool definition documentation, the CFO produces a spreadsheet that reflects current practice but has never been formalized. This is not an accounting error; it is a documentation failure. But documentation failures in GovCon diligence become EBITDA risk items because buyers cannot underwrite a normalized EBITDA that relies on a rate structure they cannot validate.

Inconsistent allocation base application. The allocation base has shifted over time — from direct labor dollars to direct labor hours, or from total labor to direct labor only — without formal documentation of the change or restatement of prior periods. Buyers will model the EBITDA impact of restating to a consistent base and use the delta as a purchase price adjustment.

Unallowable costs in the pools. FAR 31.205 defines a substantial list of cost types that are unallowable for reimbursement on government contracts — entertainment, certain marketing costs, certain legal fees, personal use of company assets, and others. A company that has not systematically segregated and excluded unallowable costs from its indirect pools is carrying contract billing risk. When the QoE team identifies unallowable items in the pools, the adjustment runs through EBITDA at the full multiple.

Rate variance that hasn't been reconciled. Provisional rates — the rates billed to contracts throughout the year — diverge from final actual rates as the year progresses. A company that has not reconciled provisional-to-actual rates quarterly, or that has significant cumulative variance at year-end, creates both billing risk and ICS complexity. Large favorable variances (billing more than actuals) create refund obligations. Large unfavorable variances (billing less than actuals) represent unbilled receivables that may or may not be collectible depending on contract type and available funding.

Business system flags. DCAA assigns risk ratings to contractor business systems based on audit findings. A company with open business system findings — particularly on the accounting system or billing system — carries a regulatory discount that sophisticated GovCon buyers will price directly into the multiple.

What a buyer's QoE team actually does

A GovCon-experienced QoE team runs a specific protocol on the rate structure. Understanding what they examine allows a seller to prepare before the process rather than during it.

They will ask for the three prior years of indirect rate budgets (provisional rates), the actual rates from each year, and the ICS submissions that reconcile them. If ICS submissions are not current, the examination stops there and the buyer models an escrow for the open years.

They will ask for the cost accounting disclosure statement (DS-1) if the company is CAS-covered. If it exists, they will test whether the company's actual practices match the disclosed practices. Deviations between practice and disclosure are a FAR violation and an escrow item.

They will select a sample of direct and indirect cost transactions and trace them to their pool allocation to verify that the pool definitions are applied consistently. They are looking for costs that should be in one pool appearing in another, or direct costs misclassified as indirect.

They will test the unallowable cost identification process — asking for the company's unallowable cost policy, the mechanism by which unallowable costs are flagged in the accounting system, and a sample of unallowable cost exclusions for the most recent year.

They will model the sensitivity of EBITDA to rate structure changes — what happens to normalized EBITDA if the allocation base shifts, if unallowable costs are excluded, if provisional-to-actual variances are recognized. This modeling produces the purchase price adjustment range.

Building a transaction-ready rate structure

The preparation timeline matters. A rate structure that needs to be rebuilt — new pool definitions, corrected allocation bases, unallowable cost remediation, outstanding ICS filings — takes 12 to 18 months to stabilize. Trying to remediate under diligence pressure compresses that timeline and creates exactly the kind of uncertainty buyers use to justify price reductions.

The deliverables that constitute a transaction-ready indirect rate structure:

If any of these deliverables does not exist or has not been updated recently, the gap should be addressed before the banker engagement — not discovered during it. A QoE team that has to construct the rate structure documentation during diligence will price the uncertainty, not the underlying compliance.

The GovCon CFO's role in rate structure management

Indirect rate structure management is a specialized skill. Commercial CFOs who have not worked in GovCon environments typically underestimate the complexity and the stakes — both the compliance obligation and the transaction value it protects. The companies that arrive at a sale process with a clean, documented rate structure have almost always had a GovCon-experienced finance leader managing it for years, not months.

For a company preparing for a transaction in the next 12 to 24 months, this is the primary argument for deploying a GovCon fractional CFO rather than continuing with a generalist finance function. The rate structure documentation, the ICS filings, the unallowable cost remediation, the provisional-to-actual reconciliation cadence — these are not general finance tasks. They are GovCon-specific, and the cost of doing them wrong is measured in enterprise value, not just operational friction.
