The decrease in the rate for the three and six months ended October 29, 2016 was primarily due to the prior year impact of cash repatriation and transaction-related costs incurred in connection with the acquisition of Animal Health International, Inc.

In the first quarter of fiscal 2016, we approved a one-time repatriation of approximately $200,000 of foreign earnings. This one-time repatriation reduced the overall cost of funding the acquisition of Animal Health International, Inc.
