Product Warranties	We accrue for warranty costs as part of our cost of sales based on associated material product costs, technical support, labor costs, and costs incurred by third parties performing work on our behalf. Our expected future costs are primarily estimated based upon historical trends in the volume of product returns within the warranty period and the costs to repair or replace the equipment. When products sold include warranty provisions, they are covered by a warranty for periods ranging generally from one year to two years.
Earnings Per Share	Basic earnings per share is computed by dividing net income attributable to Trimble Inc. by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to Trimble Inc. by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan, restricted stock units, and contingently issuable shares.
