Facts

Marceau invested $20 million in Sonitrol through a stock purchase, a note, an option agreement, and a shareholders agreement, all negotiated against Sonitrol's projected earnings. Section 4.7 of the Purchase Agreement gave Marceau the right to buy additional Class B shares for $1 per share if Sonitrol's net after tax earnings for 1989 and 1990 fell below stated thresholds, and the Shareholders Agreement canceled Flemming's put right if 1990 NATE were at or below $1.3 million. After Sonitrol's performance lagged, Flemming changed accounting treatments to improve reported earnings and later attempted to rely on UK GAAP, though the litigation proceeded on the basis that US GAAP governed. Sonitrol also departed from the amortization policies stated in the Exhibit Financials, and had those exhibit policies been used for 1990, Sonitrol's NATE would have been $1,118,000 rather than above $1.3 million.

Issue

First, under Section 4.7, did Marceau have the right to purchase additional Class B shares, and if so how many? Second, did Section 7.2 and the Exhibit Financials require Sonitrol to use the accounting policies stated in those exhibits, such that Flemming's put right was canceled because 1990 NATE would then fall below $1.3 million?

Rule

Contract interpretation is reviewed de novo. If contract language is unambiguous, the court applies its plain meaning and does not consider extrinsic evidence; in doing so, the court should interpret the agreement to give effect to all provisions and avoid constructions that render terms illusory or meaningless. Where an agreement provides that statements in attached exhibits are deemed representations or warranties, those statements can operate as warranties that the represented accounting policies will remain true in the future.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In a stock purchase agreement negotiated in Denver, an investor already owns 45% of a startup's common stock. The agreement says that if the company's 2025 net earnings are below $2 million, the investor may buy enough additional shares so that its post-purchase ownership equals the lesser of (x) 8,000,000 divided by [10 × (2025 net earnings minus $200,000)] and (y) 70% of the company's outstanding stock. Using the agreed figures, clause (x) yields 1.25.

The company argues that 1.25 means 1.25%, so the investor gets no additional shares because it already owns 45%. Which is the best answer?

Explanation. Where the contract language is unambiguous, the court applies its plain meaning without resort to extrinsic evidence. A numerical result like 1.25 in this structure is treated as a whole number that translates into 125%, not 1.25%. The investor therefore is entitled to purchase enough shares to reach the contractual cap of 70%. This follows the majority's reasoning that reading the result as 1.25% would distort the formula and defeat the provision's operation. (Derived from Sonitrol Holding Company v. Marceau Investissements (1992).)
