Publicis, the French advertising and marketing company, has returned to the equity-linked market to raise money less than a month after it first used the instrument.

The company issued a €690m ($615m) convertible on Thursday, just one day after shareholders gave it permission to issue convertible bonds worth up to €800m. Publicis's first foray into the equity-linked market, a €174m exchangeable into Interpublic Group of Companies (IPG), a US advertising company, came in December 2001.
