I'm also seeing this "extra digit" in option chains on PBCT, WFC, XRX, and MRK. -edit to remove extremely long line- Edited by DTN_Steve_S on Apr 5, 2013 at 12:44 PM

Per the new OSI symbology, symbols can have a numeric identifier after the ROOT symbol but before the date. As a result, these symbols break down as follows: S1 - root 10 - expiration year 19 - expiration day F - expiration month/PutCall (June/Call) 2.5 - Strike Hope this helps.
