The Cost of an Interim: What a Caretaker Quarter Actually Costs

An interim appointment reads like a pause. The board buys time, names a steady hand to hold the seat, and tells itself the clock has stopped while it runs a proper search. It has not stopped. An interim is not a neutral gap in the record. It is a period the company tends to underperform through, and the bill for it lands whether or not anyone writes it down. A caretaker quarter is one of the most quietly expensive things a board can choose, and most boards choose it without pricing it at all.

The choice is being made more often than it used to be. Across the U.S. companies Challenger, Gray and Christmas tracks (public, private, government and nonprofit), 18 percent of incoming CEOs in the first quarter of 2025 were named on an interim basis, against roughly 6 percent in the same period a year earlier (Challenger, Gray and Christmas, Q1 2025). That is not a rounding shift. It is a tripling, and it arrived in a year of record turnover on two separate measures. CEO exits at publicly traded U.S. companies reached 446 for 2025, against 373 the year before. Across all the U.S. companies Challenger tracks, the first quarter of 2025 recorded 646 CEO exits, the highest quarterly total on record (Challenger, Gray and Christmas, 2025). More seats are opening, and more of them are being filled by a placeholder rather than a successor. The interim rate is not a curiosity in the data. It is the clearest signal a board can send that a seat opened before anyone was ready to hold it.

An interim is not a free pause

The instinct to treat an interim as costless comes from how it looks on paper. The role is filled. Someone credible is in the chair. The board has bought itself room to be deliberate. Nothing appears to have been lost.

What is lost does not appear on that page. The academic record on this is unflattering. Research on interim CEO successions finds they are associated with lower firm performance during the period the interim serves, and that the effect depends in part on whether the interim also serves as board chair (Ballinger and Marcel, Strategic Management Journal, 2010). The direction is intuitive once named. An interim leader is, by definition, not mandated to set direction. They are asked to keep the lights on, not to make the call that reallocates capital, kills the failing initiative, or commits the company to the next bet. So those calls wait. Decisions that need an owner defer to a leader who was explicitly not given ownership. The organization idles in a higher gear than it looks like from the outside, and idling has a price even when nothing visibly breaks.

That price compounds the longer the caretaker period runs. A quarter of deferred decisions is recoverable. Two or three quarters of a company steering by momentum, while a search runs and the market watches, is how a stall becomes a slide. The interim did nothing wrong. The interim was never the point. The cost is structural to the arrangement itself.

Where the caretaker quarter actually charges the company

The interim period draws down the same cost stack as a failed executive transition, just in a slower and more forgivable-looking form. Decisions defer, and the strategic ones that move enterprise value are the first to wait for a permanent owner. Initiatives lose their sponsor, because the person who would have carried them is either gone or holding the seat on borrowed authority. The people one layer down read the vacancy accurately and update their own plans, and some of them leave, because a company visibly between leaders is a company whose direction is negotiable. Customers and lenders price the uncertainty into how much they are willing to commit. None of it resolves into a single number, which is exactly why it is underwritten so casually, the same distributed, lagged, never-a-line-item pattern that hides the key-person risk underneath.

There is a second charge specific to the interim itself. A caretaker period is a public admission that the bench was not ready, and it starts a countdown the board is now running under pressure. The search that follows is conducted on the interim's clock, not the board's, and searches run under duress tend toward the expensive end: the premium to move quickly, the external hire made because no internal candidate was ready, the compromise candidate accepted because the caretaker quarter cannot become a caretaker year. The interim did not cause that pressure. It made it visible.

Why boards keep reaching for it

Boards reach for the interim because it is the honest move available in a dishonest situation. The seat is open, the successor is not ready, and someone has to sign. Given those facts, an interim is often the right call. The problem is not the interim. The problem is arriving at the moment where an interim is the only remaining option.

That moment is almost never a surprise in hindsight. The departure that forced the placeholder was usually legible in advance: a long-tenured leader closer to the exit than the roster implied, a named successor who was named on confidence rather than documented readiness, a seat the board reviewed once a year and assumed was covered. The interim is what a board reaches for when the readiness gap it never measured turns into a seat it suddenly has to fill. The caretaker quarter is the readiness gap presenting its invoice.

The finance seat makes this sharper. A change at the top frequently forces a change one seat down, and CFO succession is already the most underinsured seat on most boards. An interim CEO governing alongside an unsettled finance function is two caretaker seats at once, each drawing down the same account.

Governing the seat before it needs a placeholder

The way to lower the cost of an interim is not to run the interim better. It is to reach the transition without needing one. That is a governance problem, not a search problem, and it is the case for leadership risk infrastructure: succession run as a live instrument rather than an annual slide. A board that can see, this quarter, which seats are closest to turning over and how ready the named successor behind each one actually is, is a board that rarely gets caught reaching for a placeholder. A board holding last year's roster review is the one that reaches for it most.

The record that closes the gap is specific. For each critical seat, a board should be able to answer, with evidence rather than recollection, who is the named successor, what is that successor's readiness by component, and where is the residual gap being closed on a clock. A Leadership Risk Review produces exactly that, delivered as a Board-Level Risk Snapshot: each seat, its exposure, and the readiness behind it, in a form the board can govern against. The difference it makes is the difference between a transition that hands off to a ready successor and one that hands off to a caretaker while the board runs a search under a countdown it did not choose.

AI informs the readiness. The board governs the evidence. An interim is what a board pays when that evidence was never built. The caretaker quarter is not free, it never was, and the cheapest way to avoid the bill is to know, before a seat opens, whether the person behind it can carry it now.

Request a Leadership Risk Review

If your board is one departure away from a caretaker quarter, it is already carrying the cost of an interim. It is just not named yet. A Leadership Risk Review maps the seats most exposed, scores the readiness behind each successor, and hands the board a record it can govern before a placeholder becomes the only option. Pricing starts at $7,500 and scales with scope.
