For example, there has been increasing legislative, regulatory, and enforcement interest in the United States with respect to drug pricing practices, and there has been recent interest in incorporating so-called Most Favored Nation pricing into the U.S. healthcare system, under which prices for drugs in the United States could be tied to foreign reference prices through a mechanism that is not yet defined. There have been several Congressional inquiries and proposed and enacted federal and state legislation and regulatory initiatives designed to, among other things, bring more transparency to product pricing, evaluate the relationship between pricing and manufacturer patient programs, and reform government healthcare program reimbursement methodologies for drug products. If healthcare policies or reforms intended to curb healthcare costs are adopted or if we experience negative publicity with respect to pricing of our products, if approved, or the pricing of pharmaceutical drugs generally, the prices that we charge for any approved products may be limited, our commercial opportunity may be limited and/or our revenues from sales of our products, if approved, may be negatively impacted.
