I'll turn the call over to John Reyes.
Thank you, Clem. Our first quarter core FFO per share was $1.44 compared to $1.28 last year, a 13% increase. Five items contributed to this growth. First, our same-store net operating income increased by 6.3%, adding $0.09 per share. The non-same-store properties added $0.02. Last year's acquisition of affiliated partnership interest added $0.02. Lower financing cost added $0.02. And ancillary operations, primarily our tenant reinsurance business, added $0.01.In the press release, we changed some of our presentation. First, we increased the size of our same-store pools to include properties that we have operated for the last 3 years at a stabilized occupancy level. For our U.S. same stores, we increased the pool by 10. For Shurgard Europe, the pool is increased by 13. We also modified our same-store expense classification to highlight other direct property costs, supervisory payroll and allocated overhead. Other self-storage companies may include some or all of these cost synergies in their G&A expenses. While we modified the presentation, we did not change what is included in our same-store expenses. We completed several capital transactions in 2012. We issued $923 million of preferred securities with a blended rate of 5.8%, and redeemed $833 million with an average rate of 6.7%. We had about $4 million of negative carry in the first quarter associated with these issuances. In addition, on July 2, we will redeem $173 million of our 7% Series and preferred stock. We expect to record an EITF charge of approximately $5.4 million in the second quarter. Assuming no further issuances, preferred dividends are expected to be about $7 million lower in the second quarter as compared to last year. Our weighted average preferred coupon is now 6.3%.
