Change in tax rates effect on DTA & DTL

Firm 1 has a deferred tax liability and Firm 2 has a deferred tax asset. If the tax rate decreases, the balance sheet values of these deferred tax items will:

Firm 1 Firm 2

A)

increase. decrease.

B)

increase. increase.

C)

decrease. decrease.

Using hypothetical numbers

ITE = $1,000

ITP = $2,000

If DTA ITE < ITP

$1,000 < $2000

DTL ITE > ITP

$2,000 > $1,000

If tax rates decrease for the DTA, ITP will decrease so the value of the asset decreases.

Where I have trouble is the DTL.

If tax rates decrease, ITP will decrease so why doesn;t the value of the DTL increase? Since there is a bigger difference ($2,000 - $800) instead of ($2,000 - $1,000)

The answer was C

I think I figured it out, if you reduce both the ITE and ITP side by say 10%. This lowers the size of the DTA/DTL. Is this correct?
