We perform our annual goodwill impairment test in the fourth quarter of each year. We continue to monitor our reporting units for indicators of impairment throughout the year to determine if a change in facts or circumstances warrants a re-evaluation of our goodwill. In the current year, as a part of the planned sale of our Australia, New Zealand and Asia businesses (discussed further in Note 14 of the Notes to the Consolidated Financial Statements) we transferred $10.3 million of goodwill to assets held for sale.
