Analyzing and Assessing Research and Development Expenses Advanced Micro Devices (AMD) and Intel (INTC) are competitors in the computer processor industry. Following is a table ($ millions) of sales and R&D expenses for both companies.

AMD	R&D Expense	Sales
2006	$ 1,205	$ 5,649
2005	1,144	5,848
2004	934	5,001

INTC	R&D Expense	Sales
2006	$ 5,873	$ 35,382
2005	5,145	38,826
2004	4,778	34,209

(b) Which of the following statements best describes how AMD's and INTC's balance sheets and income statements are affected by accounting for R&D costs?

R&D assets increase the balance sheets of both companies.

Accounting for R&D costs increases profitability because the expensing of R&D costs is deferred and revenues from R&D-related projects are recognized in current income.

R&D is initially recognized on the balance sheet and, subsequently, amortized (similar to depreciation of PPE).

Expensing R&D costs (rather than capitalizing and depreciating them) results in unrecorded assets on both AMD's and INTC's balance sheets.

(c) Which of the following statements best explains how we evaluate R&D spending for effectiveness and/or involvement (via R&D as a percent of sales)?

We can infer the sole effectiveness of R&D by measuring R&D expense as a percentage of sales.

Over time, the number and quality of new product introductions, number of patents, and related measures, can be compared across companies and against relative levels of R&D spending.

Because R&D costs are capitalized on the balance sheet, we can gauge the effectiveness of R&D spending by looking at the amount of R&D assets that are recognized.

R&D costs typically remain constant in absolute dollars, but decline each year as a percentage of sales when revenues increase.
