We maintain substantial balances of cash and liquid investments as strategic assets for purposes of acquisitions and general corporate purposes, including share repurchase. Our cash, cash equivalents, short and long-term bank deposits and marketable securities totaled $427.7 million as of December 31, 2019. The performance of the capital markets is the primary factor that affects the values of funds that are held in marketable securities. While we believe we have taken a conservative approach in our investments, by investing the majority of our debt marketable securities portfolio at securities that are rated A- or higher, these assets are subject to market fluctuations and various developments, including, without limitation, rating agency downgrades that may impair their value. We expect that market conditions will continue to fluctuate and that the fair value of our investments may be affected accordingly, including, without limitation, by the economic effects of the COVID-19 outbreak.
Financial income is a component of our net income (loss). As of December 31, 2019, our investment portfolio, including cash and cash equivalents, deposits and marketable securities, had a carrying value of $427.7 million, compared with $401.1 million as of December 31, 2018. For the years ended December 31, 2019, 2018 and 2017, we had $8.8 million, $7.3 million and $4.8 million, respectively, of net financial income.
The outlook for our financial income is dependent, in part, on the future direction of interest rates, exchange rates, the amount of any share repurchases or acquisitions that we make and the amount of cash flows from operations that are available for investment. The performance of the capital markets affects the values of our funds that are held in marketable securities. These assets are subject to market fluctuations and will yield uncertain returns. Due to certain market developments, including investments' rating downgrades, the fair value of these investments may decline. If market conditions continue to fluctuate, the fair value of our investments may be impacted accordingly. Although our investment guidelines stress diversification and capital preservation, our investments are subject to a variety of risks, including risks related to general economic conditions, interest rate fluctuations and market volatility.
In particular, our investment portfolios include a significant amount of interest rate-sensitive instruments, such as bonds, which, in addition to the inherent risk associated with the debt, may be adversely affected by changes in interest rates. Changes in interest rates and credit quality may also result in fluctuations in the income derived from, or the valuation of, our fixed income securities. Interest rates are highly sensitive to many factors, including governmental monetary policies, domestic and international economic and political conditions and other factors beyond our control. For example, benchmark interest rates, such as the U.S. Federal Funds Rate, are currently relatively low, which is likely to significantly impact our investment income. Increases in interest rates will decrease the value of our investments in fixed-income securities. If increases in interest rates occur during periods when we sell investments to satisfy liquidity needs, we may experience investment losses. Conversely, if interest rates decline, reinvested funds will earn less than expected.
In terms of credit risk, our investment portfolio policy is "buy and hold," while minimizing credit risk by setting maximum concentration limit per issuer and credit rating. Our investments consist primarily of government and corporate debentures and bank deposits. Although we believe that we generally adhere to conservative investment guidelines, if turmoil in the financial markets reoccurs in the future, it may result in impairments of the carrying value of our investment assets since we classify our investments in marketable securities as available-for-sale. Changes in the fair value of investments classified as available-for-sale are not recognized as income (loss) during the period, but rather are recognized as a separate component of equity until realized. Realized losses in our investments portfolio may adversely affect our financial position and results. For example, if we had reported all the changes in the fair values of our investments into income (loss), our reported net income would have increase by $1.1 million during the year ended December 31, 2019 and would have decreased by $1.1 million during the year ended December 31, 2018. Any significant decline in our financial income or the value of our investments as a result of continued low interest rates, deterioration in the credit worthiness of the securities in which we have invested, general market conditions or other factors, could have an adverse effect on our results of operations and financial condition.
