## Product and Pipeline Developments 

Our R&D programs are managed on a portfolio basis from early discovery through late-stage development and include a balance of early-stage and late-stage programs to support future growth. Our late stage R&D programs in Phase III development include both investigational compounds for initial indications and additional indications or formulations for marketed products. Spending on these programs represent approximately 35-45% of our annual R&D expenses in the last three years. Opdivo  was the only investigational compound or marketed product that represented greater than 10% of our R&D expenses in the last three years.

The following are the developments in our marketed products and our late-stage pipeline:
