                                                        that you consider net

                                                        management considers
comparable property NOI and sales per square foot to be key
                                                        operating measures. If
so, please include this disclosure in future Exchange Act periodic

                                                        please address, as
appropriate, the impact inflation has had on this metric.

responsible for the accuracy
       and adequacy of their disclosures, notwithstanding any review, comments,
