The Cadbury Nigeria accounting scandal remains one of the most significant corporate governance breaches in Nigeria’s capital market history. What began as a celebrated success story in the fast-moving consumer goods sector unravelled dramatically in 2006, when it emerged that the company had been overstating its profits for several years.

Between 2002 and 2005, Cadbury Nigeria Plc, the local subsidiary of Cadbury Schweppes, reported strong earnings and consistent growth. Beneath the impressive numbers, however, the company’s financial statements were being manipulated to give investors and regulators a false picture of financial health. Investigations later revealed that profits had been overstated by an estimated N13 billion –15 billion, a staggering figure at the time.

The scheme involved several layers of accounting irregularities. Inventory balances were inflated to boost asset values, while revenue was recognised before it was actually earned. Some expenses were either understated or deferred to future periods to make profits appear stronger. In some instances, the company reportedly relied on bank borrowings to pay dividends, creating the illusion of solid cash generation. Fictitious rebate and trade support entries were also introduced to pad up financial results.

For years, these manipulations went undetected. The Nigerian subsidiary continued to publish rosy financial statements, and shareholders, many of whom depended on dividend payments, had little reason to question the reported performance. But by mid-2006, Cadbury Schweppes in the United Kingdom increased its oversight of the Nigerian operations and ordered a deeper review of its accounts. What followed was the uncovering of a carefully layered accounting fraud.

The fallout was immediate and severe. Managing Director, Mr Bunmi Oni, was dismissed, while Finance Director, Mr Ayo Akinkugbe, resigned. Cadbury Nigeria issued a public confession, admitting that its financial reports had been materially misstated over several years. The company’s share price plunged as investors digested the scale of the deception, wiping off significant market value and eroding trust.

Nigeria’s Securities and Exchange Commission (SEC) stepped in, launching a formal investigation. The SEC concluded that the executives had deliberately misrepresented the company’s financial position. Sanctions followed: fines were imposed on the company, and some of the executives involved were banned from serving as directors of public companies for a period. The controversy also drew scrutiny toward the company’s auditors, who were criticised for failing to detect the manipulation sooner.

The scandal went beyond the misdeeds of a few executives; it exposed deeper structural weaknesses in Nigeria’s corporate reporting environment. At the heart of the crisis were poor internal controls, weak board oversight, and intense pressure to meet earnings expectations. It also highlighted a culture in which performance optics sometimes overshadowed transparency.

In the aftermath, Cadbury Nigeria embarked on a painful but necessary rebuilding process. The board was restructured, governance frameworks were strengthened, and internal controls were overhauled. With support from its UK parent, the company undertook financial restatements and implemented stricter compliance systems. Over time, the business stabilised and gradually regained investor confidence, though the episode left a lasting reputational scar on Cadbury.

For Nigeria’s capital market, however, the scandal served as a turning point. It triggered reforms in disclosure standards, audit expectations, and corporate governance codes, reinforcing the need for independent oversight and accountability in listed companies. Regulators became more vigilant, and boards were reminded of their fiduciary duty to protect shareholders — not simply endorse management narratives.

Two decades later, the Cadbury Nigeria scandal remains a cautionary tale. It underscores how financial manipulation, even when initially masked as creative accounting, can spiral into full-blown corporate fraud. It also illustrates the cost of weak governance, not only to shareholders and employees, but to the integrity of the wider market.

In November 2010, a Lagos High Court, led by Justice Yetunde Phillips, ruled that the “purported dismissal of Mr. Oni by a letter dated 11th December 2006 and signed by Imo Itsueli, then chairman of Cadbury, was not only wrongful and unlawful, but also a repudiatory breach of Mr. Oni’s contract of employment.”

The court ordered Cadbury Nigeria to pay all of Mr. Oni’s rights and entitlements accruing till six months from the ‘wrongful’ termination.

Mr. Oni, who served Cadbury for almost 30 years, had on February 9 told the court that his actions with regard to book padding were predicated by prevailing circumstance to prevent the company from ‘shock’ at the time.
