Two firms are planning their marketing strategies.

Firm K can earn $12.5 million in profits from strategy S if firm L responds with strategy P, and $3.75 million in profit from S if L responds with strategy Q. Firm K can follow strategy T, which returns $8 million if firm L responds with strategy P and $2.5 million if L responds with strategy Q.
