Nortel Networks

Canada's most valuable company at the dot-com peak, broken up in bankruptcy and sold off business by business — the last piece, a patent portfolio, went for $4.5 billion

Defunct — Nortel no longer exists. The company filed for creditor protection on 14 January 2009 in Canada, the United States and the United Kingdom, decided in June 2009 that it would not emerge from bankruptcy, and sold its businesses one by one: the enterprise division to Avaya, optical networking and Carrier Ethernet to Ciena, the GSM business to Ericsson and Kapsch, and the CDMA and LTE access business to Ericsson. Its last major asset, a portfolio of roughly 6,000 patents, sold for US$4.5 billion in 2011 to a consortium that became known as Rockstar. Courts in the United States and Canada approved a negotiated settlement between competing creditor groups in January 2017. Nothing is made or sold under the Nortel name today, and the UK and EMEA companies were still in administration as of April 2026.

Nortel began as the manufacturing arm of a telephone company. Bell Telephone Company of Canada's charter barred it from making products other than telephones, so in 1895 it spun the manufacturing operation out into a separate business that could sell to other customers and build fire alarm boxes, police street call boxes and fire department equipment. That company, the Northern Electric and Manufacturing Company Limited, was incorporated on 7 December 1895 with $50,000 of stock capital at $100 a share, 93 per cent of it held by Bell Telephone of Canada. In January 1914 it merged with the Imperial Wire and Cable Company to form the Northern Electric Company.

For most of its first half-century Northern Electric was owned mainly by Bell Canada and by Western Electric, the manufacturing arm of the American Bell System, and it built equipment under licence from Western Electric designs. A United States antitrust settlement in 1949 forced AT&T and Western Electric to sell their stake to Bell Canada. A generation later the ownership changed again: Bell Canada Enterprises, later shortened to BCE, was formed in 1983 as the parent of both Bell Canada and Northern Telecom, and the group of Bell Canada, Northern Telecom and Bell-Northern Research was known internally as "the tricorporate".

Northern Telecom, as it was renamed in 1976, became a serious technology company rather than a licensee by going digital early. In March 1976 management announced that the company would concentrate on digital technology, and it became the first in its industry to announce and deliver a complete line of fully digital telecommunications products, marketed under the name Digital World. The centrepiece was the DMS-100, a digital central office switch serving as many as 100,000 lines, which drove revenue for close to two decades. The DMS line had been developed at Bell-Northern Research in Ottawa from 1971, and the first DMS-10 digital switch entered service in Fort White, Florida on 21 October 1977. Nortel later received a special recognition award from Canada's Telecommunications Hall of Fame for its role in pioneering digital communications.

The company adopted the shorter name Nortel for its 100th anniversary in 1995, and in 1998 it bought Bay Networks and renamed itself Nortel Networks. The Bay Networks deal was announced at $9.1 billion, with a second figure of $7.27 billion appearing in a Los Angeles Times headline of the same month; the sources consulted do not reconcile the two. What is clear is the financial effect: the stock used to pay for Bay Networks ended BCE's majority ownership.

The bubble made Nortel the largest company in Canada and one of the largest in the world. On 26 July 2000 the shares traded at C$124.50 on the Toronto exchange, and Nortel accounted for 36.5 per cent of the TSE 300 index — the other 299 companies made up the rest — with a market capitalisation approaching C$400 billion. At its height the company employed 94,500 people worldwide, 25,900 of them in Canada.

Two things then arrived at once. In October 2000 chief executive John Roth issued the first in a series of sales warnings, and the stock fell from $96 to $71 in a single day, taking the TSE 300 down 840 points. Frank Dunn, who succeeded Roth, presided over a restructuring that cut about two-thirds of the workforce and included writedowns of nearly US$16 billion in 2001 alone. By August 2002 the market capitalisation had fallen from C$398 billion to less than C$5 billion.

Then came the accounting scandal. In October 2003 Nortel said it would have to restate its finances back to 2000. In March 2004 two senior finance executives were put on leave, and on 28 April 2004 they were dismissed along with Dunn after the company revealed that its 2003 profit would be halved; an accounting review had found irregularities. The United States Securities and Exchange Commission charged four additional former officers in 2007, the RCMP charged Dunn and two colleagues with fraud in 2008, and Nortel paid US$575 million and 629 million common shares in 2006 to settle a class action accusing it of misleading investors. In December 2014 the remaining civil charges from the Ontario Securities Commission and the SEC were dropped.

The end came on 14 January 2009, when Nortel filed for protection from creditors under Chapter 11 in the United States, the Companies' Creditors Arrangement Act in Canada and the Insolvency Act 1986 in the United Kingdom. It was the first major technology company to seek bankruptcy protection in the financial crisis, and it had a $107 million interest payment due the next day. The filing triggered a 79 per cent decline in the share price, and the case became the largest bankruptcy in Canadian history.

In June 2009 the company announced that it no longer planned to emerge from protection and would sell all of its business units. Nortel shares were delisted from the Toronto Stock Exchange on 26 June 2009 at $0.185. The reasons given in the record are the worsening recession, which deterred bidders, and large customers reconsidering their relationships with a company in restructuring.

The asset sales were run as auctions, and the recorded prices are specific. Avaya won the global Enterprise Solutions business with a bid of US$900 million in cash, plus a $15 million pool reserved for employee retention, announced on 14 September 2009 — after a stalking horse bid of $475 million in July. Ciena won the Optical Networking and Carrier Ethernet businesses, known as Metro Ethernet Networks, for US$530 million in cash plus US$239 million of convertible notes, announced on 23 November 2009, with a commitment that at least 2,000 employees would receive offers. Ericsson and Kapsch CarrierCom were the joint winning bidders for the GSM and GSM-R business at US$103 million, announced on 25 November 2009, with Ericsson taking North America and Kapsch the European and Taiwan operations. Nokia Siemens Networks made a stalking horse bid of $650 million for the CDMA and LTE access assets, and Ericsson won the auction at $1.13 billion. Nortel's UMTS access business, by contrast, had gone to Alcatel-Lucent far earlier, closing on 31 December 2006 for $320 million with about 1,700 employees transferring.

Smaller disposals followed: the Carrier VoIP and Application Solutions unit went to GENBAND, Nortel's share of its joint venture with LG Electronics went to Ericsson for US$242 million in June 2010, the Multi-Service Switch division to Ericsson for US$65 million in September 2010, and the Ottawa campus on Carling Avenue to Public Works and Government Services Canada for C$208 million in October 2010.

The final asset was the patent portfolio: approximately 6,000 patents and applications covering wireless, 4G, data networking, optical, voice, internet and semiconductor technology. Google opened with a stalking horse bid of $900 million and then raised it through a series of joke figures — $1,902,160,540 and $2,614,972,128, both mathematical constants, and finally $3.14159 billion, a reference to pi. It lost. The winning bid of US$4.5 billion came at a week-long auction in New York in June 2011 from Rockstar Bidco, a consortium of Apple, BlackBerry, Ericsson, Microsoft and Sony, which reorganised as the Rockstar Consortium. Wikipedia's Nortel article also lists EMC among the buyers; the consortium's own article does not mention EMC, and the point is unresolved. Courts approved the sale in July 2011.

Rockstar then spent the money on litigation. In October 2013 it sued eight companies, including Google, Huawei and Samsung, along with Asustek, HTC, LG Electronics, Pantech and ZTE, over the Nortel patents. Google countersued in December 2013, a settlement was reported in November 2014, and in December 2014 Rockstar agreed to sell 4,000 of the patents to RPX Corporation, a defensive patent aggregator, in a deal reported at $900 million.

What the collapse did to pensions, without embellishment. The bankruptcy left pensioners, shareholders and former employees with very large losses, and pension obligations were one of the pressures on the estate. In Canada, the court-appointed monitor reported in February 2010 that the assets of Nortel's Health and Welfare Trust had a shortfall of $37 million in net assets as of 31 December 2008, and Nortel negotiated a $57 million deal to wind up health care and other benefits for former Canadian employees. In August 2010 retired employees protested cuts, with the CBC reporting that they would lose close to 40 per cent of their Nortel pensions by the end of that month and that medical coverage would be cut by the end of the year. In the United Kingdom, the administrators of Nortel's British subsidiary lost an appeal in October 2011 against a court order requiring them to pay £2.1 billion into the underfunded Nortel pension plan; the Financial Support Direction proceedings against the Nortel companies are recorded in a December 2010 High Court judgment. Wikipedia states that Nortel's United States retirement income plan is now managed by the Pension Benefit Guaranty Corporation, a claim that could not be confirmed against the agency's own records.

The money did not all go to creditors. The CBC reported in 2016 that lawyers and accountants had received C$2.5 billion from Nortel's estate, and that former executives had collected US$190 million in retention bonuses since the bankruptcy.

The endgame was slow. The Wikipedia infobox gives the company a defunct date of 2 February 2013, which the article body does not corroborate. A pact between the American and European divisions was approved by a United States court in January 2014. The bankruptcy went back to court in April 2016. In January 2017 courts in the United States and Canada approved a negotiated settlement among competing creditor groups, clearing the way for a distribution to creditors; press reports put the amount at US$7 billion in some accounts and US$7.3 billion in others. The UK and EMEA companies, however, are still being administered: the administrators' website recorded a final progress report and a notice of a move from administration to dissolution for Nortel Networks UK Limited in April 2026, alongside a notice of an eighth and final dividend in January 2026. The site's footer still carries a Nortel Networks copyright notice.
