The ratchet begins with ordinary credit analysis: repayment capacity, leverage, cash flow, and an appropriate base coupon. The lender then adds measurable extra-financial objectives tied to the borrower's real operations, such as emissions reduction or production-process improvements. A baseline, target, reporting method, and verification process are agreed before funding. If the borrower achieves the specified outcomes, its coupon falls by a predetermined amount. The lower cost of debt can improve return on equity, giving management a direct financial reason to invest in impact improvements. Investors retain credit discipline while directing capital toward measurable change, and borrowers benefit only when verified performance converts stated commitments into results.

Origin

Extracted from Masters in Business, where Mathieu Chabran described TKO Capital's private-credit financing that reduces a borrower's coupon after specified extra-financial targets are achieved.

Core principles

  • 01Preserve conventional credit underwriting
  • 02Add measurable extra-financial targets as a third dimension
  • 03Tie verified improvement to a meaningful financing benefit
  • 04Use lower funding costs to increase the borrower's return on equity
  • 05Align financial and impact outcomes instead of treating impact as philanthropy

How to run it

  1. 1

    Complete conventional underwriting

    Assess leverage, earnings, cash flow, collateral, and repayment risk before introducing any impact incentive.

    Pro tip Set the base coupon exactly as you would for a conventional credit.

    Watch out Impact potential must not compensate for an unfinanceable borrower.

  2. 2

    Select material impact outcomes

    Choose extra-financial metrics connected to the borrower's core operations and capable of producing meaningful improvement.

    Pro tip Favor outcomes management can influence directly, such as emissions intensity or a production-process change.

    Watch out Peripheral targets invite greenwashing without changing the business.

  3. 3

    Establish the baseline

    Document current performance and the methodology that will be used to calculate future results.

    Pro tip Use normalized, auditable data and define organizational boundaries in advance.

    Watch out An ambiguous baseline makes later achievement impossible to judge fairly.

  4. 4

    Set quantified targets

    Specify the amount of improvement, deadline, evidence required, and any conditions affecting eligibility.

    Pro tip Make targets demanding but operationally attainable.

    Watch out Targets that would occur without action create a subsidy rather than an incentive.

  5. 5

    Price the ratchet

    Define the coupon reduction that follows verified achievement and ensure it is large enough to influence behavior.

    Pro tip Model how the lower funding cost affects return on equity and investment payback.

    Watch out A trivial price adjustment will not justify meaningful operational change.

  6. 6

    Verify performance

    Collect agreed data and independently confirm whether the targets were achieved before changing the coupon.

    Pro tip Use consistent reporting periods and predetermined verification standards.

    Watch out Self-reported outcomes without controls undermine credibility.

  7. 7

    Monitor both dimensions

    Continue tracking credit quality and impact performance throughout the loan rather than treating target achievement as a one-time exercise.

    Pro tip Report financial and extra-financial results together.

    Watch out Improved impact metrics do not remove conventional default risk.

In the wild

Coupon reduction for operational improvement

A profitable company borrows at a five-percent coupon under ordinary credit metrics. The facility specifies a verified reduction target or production-process change. If the company meets that target, its coupon falls to four percent, reducing financing costs and improving return on equity.

→ The borrower receives a financial reward for measurable impact while the lender retains standard credit underwriting.

Energy-efficiency retrofit financing

A mid-market building operator receives a loan with a coupon ratchet tied to independently verified reductions in energy use per occupied square meter. It funds insulation and control-system upgrades, reports normalized consumption, and earns the lower rate after meeting the agreed threshold.

→ Operational savings and cheaper debt reinforce each other while producing measurable emissions reductions.

Common mistakes

Replacing credit analysis with impact

The extra-financial dimension supplements traditional underwriting; it does not eliminate repayment and leverage risk.

Rewarding vague promises

A coupon ratchet needs quantified targets, a baseline, and credible verification rather than broad sustainability language.

Choosing immaterial metrics

Targets disconnected from core operations can be achieved without producing meaningful impact.

Is it for you?

Best for

It is best for profitable borrowers that can measure and materially improve environmental or social outcomes through operational changes.

Not ideal for

It is not ideal when targets are immaterial, unverifiable, easily manipulated, or unrelated to the borrower's core activity.

From the transcript

“We take all the traditional credit metrics of a financial analysis, and then we add a third dimension.”

“If you hit certain target, certain goals, extra financial goals, then you will improve your cost of funding”

“it's not about being a philanthropy, it's about you know, making sure that we use the capital available to send it, you know, where it…”
