Long-Term |  |  |
Equity investments - without readily determinable fair value | $ | 55 |  |  | $ | 101 |

Total long-term investments | $ | 133 |  |  | $ | 175 |
Equity investments without readily determinable fair value (RDFV) consist of non-marketable equity securities issued by private companies and include VIEs. These investments are accounted for using the measurement alternative at cost adjusting for impairments and observable price changes (orderly transactions for the identical or a similar security from the same issuer). The adjustments are included in net income in the period in which they occur. Other investments with RDFV consist of shares we own in a special fund and are reported at fair value, with gains or losses resulting from changes in fair value included in net income. Trading securities, which are comprised of mutual funds, bonds and other similar instruments, other investments and deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in net income. Our investments without RDFV and marketable equity securities with RDFV are subject to periodic impairment review. The impairment analysis requires significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of the investment. Gains and losses reflected in other income (expense), net for our equity investments with RDFV and equity investments without RDFV are summarized below:

Unrealized gain (loss) on equity securities held as of the end of the period | $ | (41) |  |  | $ | 6 |  |  | $ | (26) |
