Where:
FELi = The FEL to which the engine family is certified.
ULi = The useful life of the engine family.
Productioni = The number of vehicles in the engine family.

(i) Our review discovers an error in your end-of-year report that increases your credit balance | The discovery occurs within 180 days of receipt | Restore the credits for your use. |
(ii) You discover an error in your report that increases your credit balance | The discovery occurs within 180 days of receipt | Restore the credits for your use. |
(iii) We or you discover an error in your report that increases your credit balance | The discovery occurs more than 180 days after receipt | Do not restore the credits for your use. |
(iv) We discover an error in your report that reduces your credit balance | At any time after receipt | Reduce your credit balance. |
Bonus credit = Y * [(0.8 g/km - Certified emission level)] * [(Production volume of engine family) * (Useful life)]

Deficit = (Emission Level - Average Standard) * (Total Annual Production) * (Useful Life)
Credit = (Average Standard - Emission Level) * (Total Annual Production) * (Useful Life)
