You form a collar by buying a put with an exercise price of X1 = $39 and a premium of P = $5, and selling a call with an exercise price of X2 = $108 and a premium of C = $5. Both options mature in 7 months, and both have the same underlying asset. In addition, you buy the underlying asset for its current spot price of S = $60. Find the profit of this collar at expiration if the ending price of the underlying asset is ST = $13. Do NOT use the $ symbol in your answer; just write a numerical value. Of course, include the negative sign if the answer is negative; but do not include the positive sign if the answer is positive.
