Financial Assets and Liabilities – BPP question

Sir,

Can you please explain the question below?

A company issues $20m of 4% convertible loan notes at par on 1 January 2009. The loan notes are
redeemable for cash or convertible into equity shares on the basis of 20 shares per $100 of debt at the
option of the loan note holder on 31 December 2011. Similar but non-convertible loan notes carry an
interest rate of 9%.
The present value of $1 receivable at the end of the year based on discount rates of 4% and 9% can be
taken as:
4% 9%
$ $
End of year 1 0.96 0.92
2 0.93 0.84
3 0.89 0.77
Cumulative 2.78 2.53
Show how these loan notes should be accounted for in the financial statements at 31 December 2009.
