Addison Co. has one temporary difference at the beginning of 2010 of $500,000. The deferred tax liability established for this amount is $150,000, based on a tax rate of 30%. The temporary difference will provide the following taxable amounts: $100,000 in 2011; $200,000 in 2012, and $200,000 in 2013. If a new tax rate for 2013 of 20% is enacted into law at the end of 2010, what is the journal entry necessary in 2010 (if any) to adjust deferred taxes?
