The most important asset in your portfolio may be depreciating without appearing anywhere in the financials.
Boards know how to detect the depreciation of machinery, software, inventory, and working capital. Most cannot detect the depreciation of the operating capability of the teams that run the business. The asset sits on no balance sheet. It appears in no due diligence. It does not show up in any quarterly report. And yet it determines whether the company compounds during the hold, or quietly erodes until the multiple at exit reflects the gap.
That asset is the operating capability of the people who carry the business. Their institutional memory of customers. Their accumulated judgment about what works and what fails. Their informal networks of trust that accelerate decisions. Their ability to read weak signals before the dashboards catch them. And in most portfolio companies, this asset is depreciating without alert, without measurement, and without any line in the Value Creation Plan.
The depreciation mechanism
Operating capability does not vanish in a single quarter. It depreciates through second-order effects that financial reporting cannot capture in real time. Replacement costs, when they finally appear, only show the tip of what was lost.
Gallup documents that replacing a manager or leader costs approximately 200 percent of annual salary, a technical professional 80 percent, a frontline worker 40 percent. The Center for American Progress estimates that the cost of replacing an executive can reach 213 percent of annual salary. These numbers reflect recruitment and onboarding. They do not reflect the institutional memory that walked out, the customer relationship that was rebuilt from scratch, or the decision quality that degraded because the people who had context are no longer in the room.
The visible cost surfaces in Q3. The invisible cost surfaces three to six quarters later, in metrics the board no longer connects to the original event. By that point, the depreciation has compounded across multiple cohorts of departure, multiple managers in churn, multiple decisions made by people without context. The asset is gone before the report shows it.
The three indicators that matter
Most board reports show total turnover and overall headcount cost. Both are too coarse to detect depreciation in motion. The three indicators below are observable in HR and finance systems the board already has. No new instrument is required. Just the discipline to look at numbers that have been sitting in the data room all along.
Manager-to-operator ratio drift
When the ratio of managers to individual contributors grows beyond what the business model justifies, the company is adding coordination layers because the existing layers are no longer holding. This often follows a period where the operating capability of the teams has dropped, and supervisors get added to compensate for what capable teams used to do without supervision. The drift is visible in finance data, not just HR data. It connects capability depreciation to the operating model directly. Two or three quarters of drift without a corresponding business model change is the strongest signal of an operating asset in depreciation. This indicator is the one most boards do not have.
High-performer voluntary turnover
Most board reports show total turnover, which dilutes the signal. The number that matters is the voluntary departure rate of the top performers, measured separately. When this number rises, the asset is depreciating before any other financial indicator moves. Total turnover can stay flat while the top 20 percent walks out. By the time the financials reflect it, the institutional memory at the leadership pipeline level is already gone.
Internal promotion ratio for management hires
In a healthy organization, the operating teams produce their own future leaders. When the rate of internal promotion drops below the historical baseline of the company, the internal pipeline is breaking. The company is buying externally what it should be producing internally. The threshold is not universal. It depends on growth phase and sector. The discipline is to track the trend over multiple quarters, not to apply an abstract benchmark.
The reframing
The conviction that operating capability is a balance sheet asset is not a soft statement. It is an economic one. Gallup’s Q12 meta-analysis, the world’s largest study tying workforce performance to business outcomes, shows that work units in the top quartile of operating capability outperform the bottom quartile by 21 percent on profitability, 18 percent on productivity, and 43 to 59 percent on turnover. France Invest documented in 2025 that structured value-sharing arrangements within portfolio companies produce measurable performance gains, citing research that quantifies the lift at up to 15 percent through stronger team commitment. Capable teams compound institutional memory over time. Depleted teams dissipate it.
The asset is real. The instruments to measure it are already in your systems. Two or three of these indicators trending the wrong way without a corresponding business model change means the asset is depreciating. The financial consequences arrive three to six quarters later. The buyer at exit will see them in due diligence.
The balance sheet does not show the asset. That is not because the asset is not there. It is because nobody dared to value it. And what is not valued does not get defended.
