WORKBOOK — THE CORPORATE EXECUTIVE

Chapter VII.06 · Watershed as the Unit of Account

For the person with a P&L, a signature limit, a board, and a quarter. This workbook uses the language of the firm without apology, because the firm's own numbers already support most of what follows — they have simply never been arranged by catchment.

THE PREMISE, STATED COMMERCIALLY

Your water number is not auditable, and you already suspect it.

Litres withdrawn, by a group, in a year, across a set of sites in different countries, is a sum of quantities that have nothing to do with one another. It cannot be reconciled against anything, because there is nothing it has to equal. That is why it never moves a capital decision, why the assurance on it is limited rather than reasonable, and why your investor relations team quietly hates it.

Re-cut the same data by catchment and it becomes an account. Inside a watershed boundary the physics imposes an identity — precipitation equals evapotranspiration plus outflow plus the change in storage plus a residual — and an identity is what makes a number checkable. Australia has already written this as an accounting standard, with a statement of water assets and water liabilities and an assurance regime modelled on financial audit.

The commercial consequence is direct. Where your site sits in a basin whose books do not close, you hold an unpriced liability: an abstraction licence that will be cut, a shared aquifer that will be capped, a cost of treatment that will rise because somebody upstream changed land use. Where your site sits in a basin whose books do close, you hold something rarer — a quantified exposure, which is a hedgeable one.

This workbook takes you from the first to the second in one quarter, at a cost of roughly one analyst's time.

PART ONE — DISCOVERY

Days 1–30 · What your own numbers already say

Exercise 1.1 — Re-cut the water line by catchment (one week, with your controller)

Do not commission a study. Take the water data you already report and add one column: the catchment each site draws from. Most corporate water datasets are organised by legal entity or by country, which is to say by the two boundaries that have no hydrological meaning at all.

Then produce a single page ranking sites by catchment share:

        site withdrawal ÷ catchment renewable yield

Both numbers are obtainable. The first is yours. The second is published by almost every national hydrological service. The ranking will not match your volume ranking, and the mismatch is the finding: your largest water site is frequently not your largest water risk, and the small site in the stressed basin is the one that will take a production line down.

Exercise 1.2 — Price what you already avoid (three days)

Find the treatment or abstraction cost your sites currently pay, and the cost they would pay if source quality deteriorated one step. Your engineers know this number; it is in the design basis of the plant. That difference, annualised, is the value of the watershed you are currently receiving for free.

Exercise 1.3 — The appreciative board conversation (one session)

Change one question in one meeting. Replace "where is our water risk?" with:

"Where have we made a decision about water in the last three years that was clearly right for the long term and paid off sooner than we expected — and what made that possible?"

Record what comes back verbatim. You are establishing that the organisation already knows how to do this, which is a materially easier argument than the claim that it must learn.

PART TWO — THE ARITHMETIC

Days 31–50 · Price the alternative honestly

Exercise 2.1 — Price from a receipt, not an estimate (one week)

Every avoided-cost case in this field is built on an engineering estimate, and engineering estimates for water infrastructure are optimistic in a way that is now well documented. Find a completed comparable and scale from it.

Worked, and it is the case the whole field cites: New York City's Croton Water Filtration Plant entered service in 2015 at a final cost of $3.2 billion against an original projection of $800 million — a 4.0× overrun — for 320 million gallons a day. That is $10.0 million of capital per mgd, and it is a receipt.

At that realised price, filtering New York's main supply would have cost $9.0 billion at 900 mgd and $12 billion at a 1,200 mgd design. The famous 1998 estimate of $6–8 billion, endlessly quoted, was low.

The transferable discipline: when you are told an avoided cost, ask what the last comparable project actually cost when it was finished, and re-price. It will usually move your case in your favour, and it will always move your credibility.

Exercise 2.2 — Annualise it the way your treasurer will (two days)

        CRF  =  i / (1 − (1 + i)⁻ⁿ)

At 4 percent real over 40 years, CRF = 0.050523. A $9.0 billion plant therefore carries $454.7 million a year of capital charge; add operating cost of at least $100 million and the avoided total is $554.7 million a year, or $1.69 per thousand gallons delivered.

Exercise 2.3 — State your denominator (one day)

The same New York programme returns 3.7 : 1 annualised over its ten-year commitment and 10.0 : 1 annualised over the programme's life. Both are honest; neither is the number on its own. Every ratio you publish states its denominator in the same sentence, or somebody else will state a different one for you in a year you did not choose.

Exercise 2.4 — The debit nobody books (two days)

Run the Zhang, Dawes and Walker (2001) relation over your own catchment at w = 2.0 and w = 0.5. In the Catskill/Delaware basin at 1,200 mm of rainfall and 700 mm of potential evapotranspiration, forest yields 530 mm a year and pasture yields 684 — the forest yields 154.3 mm less, which across the basin is 451.9 million gallons a day against a draw of 900.

If your firm is proposing to fund tree planting upstream of a site in a quantity-stressed basin, put that debit in the paper. Farley, Jobbágy and Jackson (2005) found runoff fell 44 percent (±3) on afforested grassland and 75 percent (±10) with eucalypts. Your programme may still be right. It will not survive a competent challenge if the debit is missing.

PART THREE — DESIGN

Days 51–75 · The three terms, and the counterparty

Exercise 3.1 — Print the third term (one week)

        A*  =  t / (b − c)

Most corporate watershed programmes are priced on b and c alone. t — the fixed cost per contract of screening, contracting, verifying and enforcing — is buried in overhead, and it is the term that decides whether the scheme is viable.

Worked, in a basin shaped like most basins: a utility serving 100,000 people at 400 litres a head a day avoids $1.16 million a year at $0.30 per thousand gallons; across 10,000 at-risk hectares b is $115.71 per hectare per year. At a forgone rent of $250, b − c is negative and no parcel size clears. At $80, b − c is $35.71 and A* is 33.6 hectares. Where the median holding is 2 hectares, transaction cost is $600 per hectare against a net benefit of $35.71 — short by 17×.

Compute A* for each catchment on your list. Then obtain the median holding size from the agricultural census. Two numbers, one comparison, and you know which of your programmes are viable before you spend anything.

Exercise 3.2 — Reduce the counterparty count to one (two weeks)

The single highest-return structural decision available to you. One contract with a 3,000-hectare association carries 40 cents a hectare a year and clears by 89×, replacing 1,500 contracts and 1,124,250 pairwise relationships with one.

Your specification for the intermediary:

• Governed by the landholders it contracts for. New York's Watershed Agricultural Council is farmer-led, which is why farmers sign.
• Administration margin disclosed as a separate line. An invisible cost is an unmanaged cost. Put it on the invoice.
• Older than your programme, or built to outlive it. Your sponsor will move roles; the intermediary must not.

Exercise 3.3 — Move the settlement point (one week)

Do not contract for a hydrological outcome from a parcel. At basin scale it cannot be demonstrated — Bosch and Hewlett's threshold is that a change in cover below about 20 percent of catchment area is not detectable in streamflow, and New York's celebrated programme covers 13 percent of its own basin.

Instead:

1. Settle downstream at your intake, against a quality threshold you already monitor for a regulator. Zero marginal measurement cost, existing chain of custody.
2. Contract upstream on observable practice — the system replaced, the buffer standing, the plan followed.
3. Do attribution once, at basin scale. Never per hectare.

PART FOUR — DESTINY AND DELIGHT

Days 76–90 · Get it onto the standing pack

Exercise 4.1 — Capitalise it correctly (one week, with your auditors)

This is where most of the money is and it is an argument your finance function can win. Where the programme secures a durable interest — an easement, a covenant, a permanent land interest — it is a capitalisable asset with a defined life, not an operating expense. Where it does not, it is prepaid capacity and should be amortised over the deferral it buys.

Expensing a programme that defers a nine-billion-dollar plant is not conservatism. It is a category error that makes the cheaper option look like charity. Take it to your auditors early; it is a conversation about the useful economic life of an intangible, which they hold every year.

Exercise 4.2 — One line on the standing pack (two days)

Anything reviewed monthly persists; anything reviewed by exception does not. The line to add is not a volume. It is:

Catchment share, and avoided annual cost, for the three sites ranked highest by catchment share.

Exercise 4.3 — Name the four failure modes in the paper itself

The gauge is captured. The payment becomes an entitlement that outlives the practice. The alternative gets cheaper and the avoided cost erodes. The scheme is asked in year four to prove attribution it was never designed to prove.

Write the protective clause on day one: this is a purchase of a deferred capital decision, settled at the intake against the regulatory threshold, and it was never a purchase of a per-parcel hydrological outcome. A programme with that sentence in its own documents survives the audit. One that let the folklore stand does not.

THE NINETY DAYS ON ONE PAGE

---

BOARD PAPER TEMPLATE

Title. Catchment exposure and the deferral of [project], [site].

The decision requested. One sentence, with the number.

The exposure. Catchment share for this site. What a licence reduction of 20 percent would do to output, in units of production and in margin.

The alternative. [Project], capital cost re-priced from [completed comparable], annualised at the group's real discount rate over [n] years.

The programme. Cost per year, counterparty, settlement point, disclosed administration margin.

The number that decides it.

             PV of the capital deferral bought
        ---------------------------------------  >  1
             PV of the programme that buys it

Worked, at the chapter's basin: deferring a $9.0 billion plant by ten years at 4 percent real is worth $2.92 billion; the programme costs $450.6 million in present value. Net present value $2.47 billion. Ratio 6.5 : 1. Walk-away price $360 million a year.

Publish the walk-away price. It is the honest ceiling on what upstream can ask and the honest floor under what you should offer, and stating it converts a negotiation into a transaction.

What we could not verify. Named, listed, honest. One paragraph. Boards trust papers that have this section and discount papers that do not.

THE THREE OBJECTIONS, AND WHAT TO SAY

"We cannot prove the upstream work causes the downstream benefit." Correct, and you should be the one to say it first. At basin scale attribution is weak and the literature is clear about it. That is why the instrument is written as the purchase of a deferred capital decision settled at the intake, and why the paper says so in its own terms. You are not buying a hydrological service; you are buying a reduced probability of having to build something. Options are priced on probability of exercise, not on causation, and your treasurer prices options routinely.

"This belongs in the sustainability budget." It belongs in the capital plan, next to the asset it displaces, competing for the same money on the same test. A programme that defers a nine-figure project is not a donation with a nice story. Put it in the capital table and let it lose fairly if it is going to lose — it usually will not, and a programme that has survived the capital test is unkillable in a way a sustainability line item never is.

"The payback is longer than our horizon." Then shorten the horizon rather than the ambition. The deferral is bought a year at a time; re-price it every five years against the alternative's falling cost; and publish the walk-away price so that the day the arithmetic reverses, the decision to build is easy rather than embarrassing. A programme designed to be stopped cleanly is a programme a board will start.

APPRECIATIVE QUESTIONS FOR YOUR LEADERSHIP TEAM

Discovery. Where have we made a water decision that paid off sooner than we expected, and what made it possible? · Which of our sites sits in a basin whose numbers we already trust, and who made them trustworthy? · What are we currently receiving from a catchment for free that we have never priced?

Dream. If our water line were cut by catchment in next year's report, what would we be able to say that we cannot say now? · If we held a quantified, hedgeable catchment exposure instead of an unpriced one, what would change in the capital committee? · What would our assurance provider be able to give us a reasonable opinion on?

Design. Which single organisation upstream of our most exposed site could hold one contract for everybody? · What do we already measure for a regulator that could serve as a settlement point at no extra cost? · If we could buy one upstream practice, which one, and how would we know we had it?

Destiny. What would keep this on the standing pack after the current sponsor moves? · Whose compensation would have to move with it, and by how little? · What is the first sign we would see if this were quietly dying, and who would notice?
