The Google AdSense blog announced they have expanded the local currencies in the reports to nine more countries. The countries include Australia, Austria, Belgium, Finland, Greece, Portugal, South Africa, Switzerland, and the UK.
Here is what Google said, and read it carefully before you make any changes:
If you're located in one of these countries, you can now update your account to display earnings in your local currency. After you've updated your account, any earnings generated from advertisers paying in currencies other than your local currency will be converted daily. If you receive payments in your local currency, this means that there also won't be any additional conversions at the end of the month. However, you can still choose to receive payments in U.S. Dollars or change your payment method at any time.Before enabling local currency reports in your account, we recommend downloading and saving copies of your past reports in U.S. Dollars for your records. You can then update your account by signing in to AdSense and clicking the link in the green prompt on your Reports Overview page. You'll be asked to review and agree to a new set of Terms and Conditions. Unfortunately, we're not able to interpret the meaning of changes in our legal documents for publishers -- if you have questions or need legal advice on interpreting the new Terms, please don't hesitate to contact your attorney.
