I happened to receive an IR email from Allegion: upon further look, I realized it’s a spin off of Ingersoll Rand (I talked about IR here and here). That’s probably the time I bought the stock. I sold the IR stock long time ago (I cannot recall and don’t have a record).
Since then, the original Ingersoll Rand spined off Allegion PLC (NYSE: ALLE) in 2013. The tools business of original IR was spined off as Ingersoll Rand (stock ticker is IR). And the remaining business is mainly Trane and Thermo King are called Trane Technologies with stock ticker TT.
So one S&P 500 company essentially become 3. I don’t know if I have hold on to the stock, how much return is that? Recently I had similar experience with Honeywell and they spun off material business as Solstice.
Separately, I recall I had an onsite interview with IR in Feb 2005 (per my yahoo email), in New Jersey. They didn’t extend me the offer after interview.
