I used to work for a pre-IPO startup that had experienced a pretty big run-up in their stock price. As a result, their new hires were getting options to buy 200 shares at $100 per share. (I made up those numbers, but you get the idea.) They did a big stock split partly to change the numbers in stock option offers. Apparently it was much more enticing to offer candidates options for 2000 shares at $10 per share. Even though the options would have the same total value, they believed candidates would respond much better to an offer of "more options."
