Apple CEO Tim Cook has donated some 23,215 shares of Apple stock to an unnamed charity, according to an SEC filing uncovered by BusinessInsider. Shares of $AAPL closed at 215.04 on Tuesday, making the value of this donation worth some $4.99 million dollars today. Of course, that value will change over time, and the dividend for those shares will earn the charity $16,947 every quarter. That’s a gift of $67,788 per year that keeps on giving, and it could grow if Apple continues to increase that dividend. In other words, it’s a princely gift from a man who has already promised to give away all his wealth (after providing for the education of his young nephew).
