Strictly speaking, the annualized hike per year is $900 (the second semi-annual salary hike is not retroactively applied to the previous semester, thus raises incurred over the course of anu given year contribute only $600 + $600/2 toward that year’s salary); your hypothetical salaryman benefits from a $300 contribution from the previous semester.
