Deferred Income

Can anyone help me with this question?

A manufacturing entity receives a grant of $3 million when it creates
50 jobs. $1.5m is payable when the figure is reached with the
remaining $1.5m payable at the end of 4 years should the 50 jobs
still be in existence. At the end of year one, 50 jobs have been
created and there is reasonable assurance that the employment
levels will be maintained when reached.

What is the deferred income balance at the end of the second
year?
