Lauder Shorts own stock

A couple of quotes from the article to ponder :

"And earlier this year, Mr. Lauder used his stake in the family business, Estée Lauder Companies, to create a tax shelter to avoid as much as $10 million in federal income tax for years. In June, regulatory filings show, Mr. Lauder entered into a sophisticated contract to sell $72 million of stock to an investment bank in 2014 at a price of about 75 percent of its current value in exchange for cash now. The transaction, known as a variable prepaid forward, minimizes potential losses for shareholders and gives them access to cash. But because the I.R.S. does not classify this as a sale, it allows investors like Mr. Lauder to defer paying taxes for years."

And :

" Estée Lauder Companies went public in 1995, and Ronald Lauder and his mother cashed in hundreds of millions of dollars in stock but managed to sidestep paying tens of millions in federal capital gains taxes by using a hedging technique known as shorting against the box.

Together, Mr. Lauder and his mother borrowed 13.8 million shares of company stock from relatives and sold them to the public during the offering at $26 a share. Selling borrowed shares in this way is referred to as a short position. Since the Lauders retained their own shares, the maneuver allowed them to have a neutral position in the stock, not subject to price swings. Under I.R.S. rules at the time, they avoided paying as much as $95 million in capital gains taxes that might otherwise have been due had they sold their own shares."
