Another company’s options granting practices are being investigated by the Securities and Exchange Commission. Coherent Inc., which makes lasers for commercial and scientific uses, said it received an informal inquiry from the San Francisco office of the SEC relating to the company’s past granting of stock options.

The company, whose market capitalization is slightly less than $1 billion, assured investors that it intends to cooperate with the inquiry. As a result of the probe, however, Coherent said it will delay the filing of its annual report due to its internal review into its option practices and related accounting. Coherent also noted that it will not be able to file its annual report prior to the end of the 15-day extension provided by SEC rules. Coherent also said that it has not determined whether it needs to restate any previous financial statements or if it needs to record any non-cash adjustments.

The Associated Press said that a little more than 100 companies are currently under investigation by the SEC and/or the Justice Department for possible options backdating.
