HW No. 1. Due TUE JAN 26 page 1 of 2 The table below describes options prices for a stock MMM on AUG 25 2009. The strike prices, denoted by K, are in the leftmost column and there are four expiration months: Sep09, Oct09, Jan10 and Apr10. The stock price on August 25 was S = 27.50/share. Note, in the table, ---, means that the option does not exists or was not traded that day. Thus, for example, the premium of the call with strike price K = 30 and expiration in APR 10 was 2.40/share.

Use a calendar and Indicate the official expiration dates [the SAT immediately following the Third FR of the expiration month] of the options in the table. 2. Read CH III in the OCC publication.
