Nikko Cordial's SPC accounting fraud ended with Citigroup buying Japan's No. 3 brokerage

In late 2006 Nikko Cordial Group, Japan's third-largest brokerage, was found to have booked improper profits through subsidiary Nikko Principal Investments and unconsolidated special purpose companies. The securities watchdog's case centered on bonds Nikko issued using false securities reports as reference documents — a violation of the old Securities and Exchange Law — and in December 2006 the SESC recommended a ¥500M surcharge, at that point the largest ever for a disclosure violation. The Tokyo Stock Exchange put the stock under its supervision post, an explicit step toward delisting.

A special investigation committee of outside lawyers chaired by Masaharu Hino, the first commissioner of Japan's Financial Services Agency, reported on 30 January 2007. It singled out former president Junji Arimura and named former finance director Moto Yamamoto and former NPI chairman Hirofumi Hirano. The next day Nikko restated again: ¥4.8B of improper recurring profit in FY2005/3 from leaving SPCs unconsolidated, and ¥19.1B in FY2006/3 from SPC funding and SPC-related share sales — a revision upward of what had been announced in December.

What followed was a three-month struggle for survival: a February governance-meeting apology so vague that even the FSA reportedly despaired; major newspapers prematurely reporting delisting before the TSE decided in mid-March to keep the listing; and a tender offer by Citigroup, launched 6 March and structured to work even if the stock was delisted. Mizuho, which held 5.91% and wanted the brokerage for itself, stood down against Citigroup's 4.94% plus exclusivity rights negotiated when Nikko had rushed to Citi fearing delisting.

Record ¥500M surcharge (largest disclosure fine of its time), ¥23.9B in improper profit restated, a delisting scare, and loss of independence to Citigroup

Former management treated SPC consolidation as optional, so profits could be booked on sales whose risk had secretly stayed inside the group.

Subsidiary NPI even altered bond issuance dates; the holding company's oversight failed to catch what its own disclosures relied on.

Revenue-first culture: the committee's finding pointed at executives whose incentives rewarded showing more profit rather than showing it correctly.

Consolidation-scope judgment was concentrated in the same people who benefited from the headline number — no independent check on perimeter decisions.

Profit that depends on keeping entities off the consolidation perimeter is not profit. If a deal only works while a vehicle stays off the books, the vehicle is part of the deal.

Citigroup's tender offer ended with Citi holding 68% of Nikko Cordial. In October 2007 it announced a triangular merger to absorb the remaining 32%, allocating Citigroup shares worth ¥1,700 per Nikko share — NYSE paper needing no new cash — with full ownership expected by January 2008. Japan's third-largest brokerage vanished from the exchange it had nearly been expelled from, into a foreign group. The ¥500M surcharge stood as the disclosure-fraud record until IHI's ¥1.59B in 2008, and the TSE's decision to keep the listing remained contested as an example of exchange discretion.
