 For each threat identified, a risk rating that ranges
 from *informational* to *critical* is given based on the likelihood of the
-threat occuring if a mitigation is not in place, and the impact of the
+threat occurring if a mitigation is not in place, and the impact of the
 threat (i.e. how severe the consequences could be). Table 4 explains each
 rating in terms of score, impact and likelihood.
