The number of latecomers to this year’s 10-K filing season is down 30 percent from last year, yet another indicator that companies are adapting to life after the Sarbanes-Oxley Act.

According to research from Glass, Lewis & Co., only 203 calendar year-end accelerated filers asked for an extension of their filing deadlines from the Securities and Exchange Commission. While that number is still more than triple the number of extensions for 2003 annual reports, it is down from 288 for 2004—the first year accelerated filers had to comply with SOX.
