On 18 December 2012, the Italian Competition Authority (the plaintiff) decided to launch an investigation against the defendant, a financial institution, with regard to its advertising campaign of its deposit account "Conto Risparmio Sicuro". The advertising campaign included TV commercials, radio commercials, posters and banners on the defendant's website.
The defendant advertised that the consumers could earn up to 7% interest rate on their savings in the deposit account. However, the 7% interest rate was paid only in the fifth year the consumer had its savings in the deposit account. In the previous four year the interest rate paid by the trader was lower. The average interest rate paid by the bank during five years was around 4%. Such information was not disclosed in the advertising materials that contained only a disclaimer in very small characters which referred to the defendant's website and to the prospectus for other information.
The defendant argued that its advertising campaign was compliant with the financial regulations.
