Fixed Asset Depreciation Rates for 50%200DB, 50%MACRS, 50%STL

 Hello Everyone, would someone help me in finding out where I could get the depreciation rates for 50% Bonus depreciation?  Is there some oreacle patch I can dowload that contains all the rates?  In our 12.1.2 environment, I have no entries under setup->Depreciation->Bonus rules, I thought some would come seeded with Oracle install, but I guess not.  Any help in this would be much appreciated.
Thank You in advance for your hep.
