There’s rounding right there (23.1m * 69.35 is not a round number).
That sounds backwards to me. It looks to me like they started at the round 2.0, set 20% in cash, 80% in stock, found that required 23.1m shares of facebook and rounded that to three digits to get within 2% of the 1.6 they wanted.
Also, the incentive pay of 300m is 15% of the fixed payment, less uncertainty than rounding to 1 significant figure.
