Setting the threshold at 10% would permit a few stockholders who own a small percentage of the Company's common stock to call a special meeting that may be of limited or no concern to the large majority of the Company's stockholders, while wasting company resources and diverting management's attention away from running the business. Please vote AGAINST this non-binding stockholder proposal . We established ambitious emissions reduction targets this year and plan to measure and report our progress against them annually, but the Board requires more time to determine how that may relate to executive compensation.
