KCQ - Income Tax Calculation

I also don’t understand the income tax calculation.  The calculation shows adjustments for various income and expenses which I assume are not assessable or deductible but as my company has been making losses for consecutive years now I wouldn’t think they’d be paying any tax?  Terms in the tax calculation I don’t understand are: 

·         Deferred Tax Assets

·         Unrecognised Tax Losses

·         Temporary Differences

I'd say these terms are well beyond on ACCT11059 but any thoughts?
