Pursuant to our business combinations accounting policy, we recorded goodwill adjustments for the effects on goodwill of changes to net assets acquired during the period that such a change is identified, provided that any such change is within the measurement period (up to one year from the date of the acquisition). Amounts also include any changes in goodwill balances for the periods presented that resulted from foreign currency translations.
