And if you don't think commas can be important, consider the following, which may cost a company more than $2 million because of it. (And please read the entire story for the full effect, though I've bolded the paragraph in question — see if you can spot the problem comma):

Comma quirk irks Rogers

By GRANT ROBERTSON
From (Toronto) Globe and Mail, June 8, 2006

It could be the most costly piece of punctuation in Canada.

A grammatical blunder may force Rogers Communications Inc. to pay an extra $2.13 million to use utility poles in the Maritimes after the placement of a comma in a contract permitted the deal's cancellation.

The controversial comma sent lawyers and telecommunications regulators scrambling for their English textbooks in a bitter 18-month dispute that serves as an expensive reminder of the importance of punctuation.

Rogers thought it had a five-year deal with Aliant Inc. to string Rogers' cable lines across thousands of utility poles in the Maritimes for an annual fee of $9.60 per pole. But early last year, Rogers was informed that the contract was being cancelled and the rates were going up. Impossible, Rogers thought, since its contract was iron-clad until the spring of 2007 and could potentially be renewed for another five years.

Armed with the rules of grammar and punctuation, Aliant disagreed. The construction of a single sentence in the 14-page contract allowed the entire deal to be scrapped with only one-year's notice, the company argued.

Language buffs take note — Page 7 of the contract states: The agreement “shall continue in force for a period of five years from the date it is made, and thereafter for successive five year terms, unless and until terminated by one year prior notice in writing by either party.”

Rogers' intent in 2002 was to lock into a long-term deal of at least five years. But when regulators with the Canadian Radio-television and Telecommunications Commission (CRTC) parsed the wording, they reached another conclusion.

The validity of the contract and the millions of dollars at stake all came down to one point — the second comma in the sentence.

Had it not been there, the right to cancel wouldn't have applied to the first five years of the contract and Rogers would be protected from the higher rates it now faces.

“Based on the rules of punctuation,” the comma in question “allows for the termination of the [contract] at any time, without cause, upon one-year's written notice,” the regulator said.

Rogers was dumbfounded. The company said it never would have signed a contract to use roughly 91,000 utility poles that could be cancelled on such short notice. Its lawyers tried in vain to argue the intent of the deal trumped the significance of a comma. “This is clearly not what the parties intended,” Rogers said in a letter to the CRTC.

But the CRTC disagreed. And the consequences are significant.

The contract would have shielded Rogers from rate increases that will see its costs jump as high as $28.05 per pole. Instead, the company will likely end up paying about $2.13-million more than expected, based on rough calculations.

Despite the victory, Aliant won't reap the bulk of the proceeds. The poles are mostly owned by Fredericton-based utility NB Power, which contracted out the administration of the business to Aliant at the time the contract was signed.

Neither Rogers nor Aliant could be reached for comment on the ruling. In one of several letters to the CRTC, Aliant called the matter “a basic rule of punctuation,” taking a swipe at Rogers' assertion that the comma could be ignored.

“This is a classic case of where the placement of a comma has great importance,” Aliant said.

An interesting update (from Prof. Gibson), thanks to NPR:

I heard on NPR that the company is going to court, asking that the courts use the French version of the contract, which apparently does not contain the same comma problem. As the English/French expert said: “Only in Canada! ”
