[1] Quarterly totals may not foot across due to rounding.

[2] One week of the Anniversary Sale, historically our largest event of the year, shifted into the third quarter. Combined second and third quarter comparable sales, which removes the impact of the event shift, increased 0.4% compared with the same period last year.

[3] On October 1, 2015, we completed the sale of a substantial majority of our U.S. Visa and private label credit card portfolio to TD (see Note 2: Credit Card Receivable Transaction).

[4] Due to the anti-dilutive effect resulting from the reported net loss in the third quarter of 2016, the impact of potentially dilutive securities on the weighted-average shares outstanding has been omitted from the quarterly calculation of loss per diluted share. The impact of these potentially dilutive securities has been included in the calculation of weighted-average shares for all other periods in 2016.
