LinkedIn shares tumbled following its filing last Friday.
The professional networking site permitted stockholders of its recently-bought Lynda.com to sell roughly 3.57 million shares at their discretion.
The filing showed that the company is permitting potential sellers, including a family trust controlled by Lynda.com co-founders and other investors, to sell slightly more than 3% of its outstanding shares.
In April, LinkedIn acquired online video tutorial company Lynda.com in a cash-and-stock deal for $1.5 billion.
LinkedIn paid about 52% in cash and about 48% in stock for the acquisition.
Lynda.com offers numerous courses in categories like design, photography, business and three-dimension animation.
Subscription fees for its courses are between $250 and $375 per year, according to its website.
With the addition of Lynda.com and LinkedIn, LinkedIn's head of content said its users will know what skills are needed for the available jobs in their desired city.
The company said the acquisition deal would add to LinkedIn's hiring business, which has been helped by the booming expansion in international markets, including China.
LinkedIn builds professional networks and provides information about the job market and hiring trends. LinkedIn also offers job listings.
The company is based in Mountain View, Calif. Shares of LinkedIn ended Monday's regular session in the red on heavier trading volume compared to its daily average.
