We have outstanding stock options and unvested restricted shares, and our Operating Partnership has outstanding common OP units, convertible A-1 preferred OP units, convertible A-3 preferred OP units and Aspen preferred OP Units, which, if converted or exercised, will impact dilution.

We excluded certain securities from the computation of diluted earnings per share because the inclusion of these securities would have been anti-dilutive for the periods presented.  The following table presents the outstanding securities that were excluded from the computation of diluted earnings per share as of September 30, 2014 and 2013 (amounts in thousands):
