deferred tax

Hi mike

can you help me with the following: i do not know how to classify whether it is a deffered tax or liability.

share options
An entity, Splash has established a share option scheme for its 4 directors commencing 1/7/2008. Each director will be entitled to 25000 share options on condition that they remain with Splash for 4 years, from the date the scheme was introduced.

FV of option at grant date $10
FV of option at 30/6/2009 $12
Exercise price of option $5

The MV or FV of shares at 30/6/2009 was $7 per share. Tax allowances on any expense recognised for share options are only granted at the date when options are exercised and will be based upon the intrinsic value of the options. Tax 30%

Calculate for the yr end 30/6/9

Yr end 30/6/9
4 x 25000 x $10 x 1/4 = $250,000.> P/L

Yr end 30//6/2010
4 x 25000 x $10 x 2/4 = $500,000> P/L

On 30/6/2009-? 4 x 25000 x (17-5) x ¼ = $300,000
$300,000 @30% = $90,000 is DT asset, tax is recognised when the options are actually exercised. why DT asset? i dont understand. I would think that the entity has paid tax on $300,000 which should have been 250,000 so deferred tax asset, is this correct?

Inventory
On 30/6/2001, the complex group acquired a new sub, at the date of acquisition the sub had inventory that was shown in FS at a CA of $50,000. The group assessed the fair amount of the inventory of $55,000. Tax @ 30%.

Solution:

$5,000 additional needs to be taxed.

CV $50,000
Tax purposes $55,000
Temp diff $5,000

DT liability $1500 CR & DR COS

if i was using that assumption that i used above, the entity has paid tax on 55,000 rather 50,000, would this not be DT asset too? i am really confused.
