Dear,
This depends on whether what is the nature of Investment, let me clarify that Cash equivalents include highly liquid investments which can readily be converted into known amount of cash.
Short term investments may be considered as cash equivalent since these may be converted into almost known amount of cash, however, there could have some other factors, the consideration of which is crucial in this regard i.e. whether Mutual funds are Open End or Close End funds. If it is close end fund, then they may not be treated as cash equivalent, since they may not be readily cashed and amount to be fetched from sale is also unpredictable.
In case of Open End Fund, it is required to ascertain whether, these funds can be converted into cash when required into known amount of cash, if this is not the case then open end funds may also not be treated as cash equivalent, in the contrary, they may be considered as cash equivalent.
Hope you have been replied.
Best Regards,
Desperado.
