The Global Innovation 1000: Top 20 R&D Spenders 2005-2013

In 2013, Booz & Company adopted a new methodology to more accurately reflect companies' full R&D spending. Before, both capitalized and amortized R&D expenditures were excluded. Starting in 2013, for companies with capitalized R&D expenditures, we included the most recent fiscal year’s amortization of those costs in calculating the total R&D investment, while continuing to exclude any non-amortized capitalized costs. It is largely the result of this methodology change that rankings for Volkswagen and Daimler changed so significantly between 2012 and 2013.
