Investors are being urged to vote against a $99m (£73m) pay package awarded to Apple boss Tim Cook last year.

Axar.az informs that Institutional Shareholder Services (ISS) said it has "significant concerns" over the size of the award, up from $14.8m the year before.

Mr Cook, whose net worth is reportedly more than £1bn, received the pay in shares, salary, and for other costs.

The BBC has contacted Apple for comment.

In a letter to shareholders, the ISS said there are "significant concerns" over the "design and magnitude" of the package. "Half of the award lacks performance criteria," ISS said.

Mr Cook, 61, who has often spoken publicly about his concerns over equality and human rights issues, said in 2015 that he would give away his entire fortune before he dies.
