Equity reversion and band-of-investment method

i just did the 2011 exam paper. There were 2 questions regarding after tax equity reversion and band-of-investment cap rate. I did not find anything about these 2 concepts in the 2013 Curriculum. Are they skipped in 2013 version or I just missed out on anything here? Pls shed a light. thanks.

band of investment gone.

That type of equity reversion question - gone as well

however AI does have 2 other forms of reversion - Layer and Term reversion

thanks trogulj for the clarificiation.
