Subsequent Event [Line Items]
Subsequent Events	Subsequent Events On December 20, 2017, the Tax Cuts and Jobs Act bill was passed by Congress. Once the bill is signed into law, the change in the tax law will lower our overall tax rate and reduce our deferred taxes and will be treated as a discrete item in the quarter enacted. We will still need to assess the effect of the new law when enacted on our effective tax rate.
