Largest IPO in Utah History?

I heard today that Extra Space Storage, based in Salt Lake City, UT may have had the largest IPO in Utah history. It apparently sold 20.2 million shares at $12.50 per share, raising more than $240 million. If Yahoo Finance is correct, it\’s market cap today was $400 million, which means that it sold more than half of its outstanding shares in the IPO. Does anyone know what the largest IPOs were prior to this one?
