He came back with the same plan we had told him to change

The situation

Ratana and Priya had worked together for almost a decade by the time this deal landed on our desk. Ratana had started out as a commercial cleaner, working overnight contracts at the same logistics company's warehouses before he moved into operations and eventually into managing one of its divisions, a fleet and warehousing business based in Innisfil that the parent had decided to sell off. Priya, who had spent a stretch of her own early career as a transit operator before retraining in finance, ran finance for the parent company and had watched Ratana's rise from the ground floor. When the board approved the sale, Priya recommended Ratana as the buyer, and the two of them structured a management buyout together, Priya shepherding it from the seller's side while Ratana raised the money to close it.

This was not our first file with Ratana. Two years earlier we had advised him on a smaller acquisition, a trucking sub-business he picked up for a fraction of this deal's size, and at the time we had walked him through exactly why loading a target company with intercompany debt from a non-resident related lender creates problems under the thin capitalization rules in the Income Tax Act. Those rules do not reach every related-party loan; they apply specifically to debt owed to a specified non-resident shareholder, meaning a non-resident who owns, alone or together with people who do not deal with the company at arm's length, at least twenty-five percent of the votes or fair market value of the company's shares. Once a loan is caught, the ceiling is a 1.5-to-1 debt-to-equity ratio; interest on debt above that line simply stops being deductible, however reasonable the rate. We had recommended a different mix then, and he had taken the advice, and the deal had gone smoothly.

This time was bigger. The Innisfil division was valued in the mid-single-digit millions, and Ratana's financing plan leaned heavily on a loan from Aditya, a non-resident investor connected to the parent company's ownership group, who was taking a minority equity stake in the acquisition vehicle alongside a loan priced at a rate lower than a bank would offer. That equity stake was large enough on its own to make Aditya a specified non-resident shareholder of the company for tax purposes, which meant his loan was squarely the kind of related-party debt the thin capitalization rules were built to catch. On paper it still looked like an easy way to get the transaction financed without diluting Ratana's own control of the company. What Ratana had not done was bring us in before he and Aditya papered the loan and equity terms together.

By the time Ratana called, the loan agreement was drafted, the equity contribution was set at a level that would trigger the same thin capitalization ceiling we had flagged on the earlier deal, and the closing date was five weeks out. Priya, still representing the seller's side, was the one who suggested he call us again, having recognized the shape of the problem from the last file.

What the other side was relying on

The seller's counsel had structured their side of the deal on the assumption that Ratana's financing was Ratana's problem, not theirs, and in the narrow legal sense that was correct: nothing in the purchase agreement obligated the seller to accept a change to the buyer's capital structure. But Aditya's loan terms were priced on the interest being fully deductible, and that assumption was the load-bearing wall under the whole financing plan. If the deduction was partially denied, the effective cost of the debt rose, and Ratana's projected cash flow would not cover both loan service and the working capital the division needed to operate.

The parent company, through Priya, was relying on a fast close. The division had been flagged for divestiture for over a year, it was a drag on the parent's reporting, and the board wanted it off the books before the next fiscal quarter closed. That gave Ratana leverage he had not used the first time we worked together: a five-week runway was tight for the seller too, and a request to adjust the financing structure, if it did not touch price or the closing date, was something the seller had more incentive to accommodate than to fight.

Aditya, for his part, was relying on the deal closing on the terms already drafted. He had priced his loan as a non-resident, related-party arrangement at a rate that made sense only if the deduction went through in full. He had not budgeted for a renegotiation, and when we explained the thin capitalization exposure to him directly, his first response was that the earlier deal had used a similar structure without issue. That earlier deal, we pointed out, was smaller, and the debt-to-equity ratio it produced sat comfortably under the 1.5-to-1 threshold. This one did not.

What none of the three parties had done was model the debt-to-equity ratio against the actual thin capitalization limit before agreeing on numbers. Each side had priced its own piece of the deal on the assumption that the other pieces would simply work, which is a common failure mode in deals assembled quickly by people who trust each other and have worked together before.

Priya, however sympathetic she was to Ratana's situation, could not indefinitely shield him from the board's pressure to close, which gave the seller's side an incentive to accept a restructured financing plan quickly rather than relitigate price or terms, provided the fix did not obviously advantage Ratana at the parent's expense. Understanding which parts of the deal each side genuinely could not move on, and which parts were simply the path of least resistance under deadline pressure, shaped how we approached the renegotiation that followed.

What we did

1. Modelled the actual ratio against the statutory ceiling using the division's projected equity and the full intercompany loan amount, comparing the result against the 1.5-to-1 limit rather than a rough estimate. That confirmed the debt exceeded the permitted multiple by a meaningful margin. We needed this number before any negotiation could start, because until we knew how far over the line the structure sat, we could not tell Ratana whether a modest adjustment would fix it or whether the plan needed rebuilding.
2. Explained the mechanism to Ratana plainly, walking through what happens to the interest deduction on the excess debt and why that risk sits with the borrower, not the lender: Aditya would still get paid in full, but Ratana would lose the tax benefit he had counted on to make the loan affordable. This was the same explanation we had given him two years earlier, and this time we put it in writing.
3. Approached Priya on the seller's side early, before drafting any formal request, to gauge informally whether the parent company would accept a short extension or a change to the earnest deposit terms in exchange for Ratana restructuring his financing. Going informally first let us test the seller's appetite without committing Ratana to a formal position he might later have to walk back if the parent's board pushed harder than expected.
4. Negotiated a partial equity conversion with Aditya, converting a portion of his loan into a preferred equity position instead of debt, which brought the ratio under the 1.5-to-1 threshold without requiring Ratana to find a new source of capital on five weeks' notice. Aditya accepted a lower guaranteed return in exchange for an upside participation right tied to the division's future performance, which softened the loss of his original deal terms and kept him at the table.
5. Rebuilt the closing cash-flow model with the revised debt-and-equity structure to confirm the division could service the smaller loan balance and still fund seasonal working capital for the fleet and warehousing business in its first year under new ownership, including the slower winter months when receivables typically stretched out. A technically compliant structure that could not actually be serviced from operating cash would only have traded one problem for a second, harder one after closing.
6. Renegotiated a two-week closing extension with the seller to give the revised loan and equity documents time to be drafted, reviewed, and signed properly rather than rushed, trading a modest, non-refundable increase to the deposit for the extra runway. We deliberately avoided trying to force the original date, since a rushed signing on documents this consequential was a worse risk than a short, paid-for delay.
7. Documented the new structure with clear related-party terms so that the equity conversion and the remaining debt were each on their own footing, with separate instruments and separate return mechanics rather than one blended arrangement that tried to do both jobs at once. Clean paperwork on this point mattered because a related-party file is exactly the kind of structure a future audit or reassessment is most likely to test, and a record that clearly separated what portion of Aditya's investment was debt and what was genuinely equity gave Ratana something defensible to point to years later, instead of an ambiguous instrument that could be argued either way after the fact.
8. Briefed Ratana on how to avoid repeating this pattern on any future deal, including a written checklist for financing structures involving related-party or shareholder debt, because the underlying problem on this file was not a one-time drafting error but a process gap that had already shown up once before and would show up again on the next acquisition if it went unaddressed.

The outcome

The deal closed, roughly seven weeks after Ratana first called Priya about the acquisition and two weeks later than originally planned. The revised structure brought the debt-to-equity ratio under the thin capitalization threshold, which preserved the interest deduction on the debt that remained. That was the core of what we were able to fix.

What Ratana did not get back was the deal he had originally priced. Aditya's converted equity position gave up a fixed, predictable return in exchange for upside that Ratana now has to share if the division performs well, which was not part of the plan he brought to us. The two-week extension also cost him a modestly larger deposit, non-refundable once paid, as the price of the seller's flexibility. None of this put the acquisition at risk of falling apart, but it meant Ratana's actual cost of capital on this deal was higher than it needed to be, a direct result of the structure being drafted before the tax exposure was checked.

Priya has since asked us to review financing structures on two other files in the same holding group before terms are signed, not after. Ratana has said this was the last time he would sign anything before calling us first. The lesson from the first file did not take; the cost of the second one did.

What makes this file worth recording is not the technical fix, which was fairly standard once the numbers were modelled properly. It is the gap between advice given and advice followed. Ratana had heard the explanation once, understood it, and still moved forward on a bigger deal without applying it, because the pressure of a fast-moving, trust-based transaction with people he had worked with for years made it easy to assume the same shortcuts would scale up fine. They did not, and the difference showed up as a real cost.
