will impact our revenues and expenses. If the U.S. dollar were to weaken against another currency, assuming all other variables remained constant, our revenues would increase, having a positive impact on earnings, and our overall expenses would increase, having a negative impact on earnings. Conversely, if the U.S. dollar were to strengthen against another currency, assuming all other variables remained constant, our revenues would decrease, having a negative impact on earnings, and our overall expenses would decrease, having a positive impact on earnings. Therefore, significant changes in foreign exchange rates can impact our results and our financial guidance.

The impact of possible currency devaluations in countries experiencing high inflation rates or significant exchange fluctuations can impact our results and financial guidance. For example, on February 13, 2013, the Venezuelan government devalued its currency from a rate of 4.3 to 6.3 of Venezuelan currency to the U.S. dollar. We incurred a foreign currency loss of $80 million immediately on the devaluation as a result of remeasuring the local balance sheets, and we have experienced and will continue to experience ongoing adverse impacts to earnings as our revenues and expenses will be translated into U.S. dollars at a lower rate. We cannot predict whether there will be further devaluations of the Venezuelan currency or devaluations of any other currencies.

Despite the challenging financial markets, Pfizer maintains a strong financial position. Due to our significant operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have, and will maintain, the ability to meet our liquidity needs for the foreseeable future. Our long-term debt is rated high quality by both Standard & Poor’s (S&P) and Moody’s Investors Service. As market conditions change, we continue to monitor our liquidity position. We have taken and will continue to take a conservative approach to our financial investments. Both short-term and long-term investments consist primarily of high- quality, highly liquid, well-diversified and available-for-sale debt securities. For further discussion about our financial condition, see the “Analysis of Financial Condition, Liquidity and Capital Resources” section of this Financial Review.

These and other industry-wide factors that may affect our businesses should be considered along with information presented in the “Forward- Looking Information and Factors That May Affect Future Results” section of this Financial Review and in Part I, Item 1A, “Risk Factors,” of our 2013 Annual Report on Form 10-K.

Our Strategy

We believe that our medicines provide significant value for both healthcare providers and patients, not only from the improved treatment of diseases but also from a reduction in other healthcare costs, such as emergency room or hospitalization costs, as well as improvements in health, wellness and productivity. We continue to actively engage in dialogues about the value of our products and how we can best work with patients, physicians and payers to prevent and treat
