[1] Based on calculations that use readily observable market parameters at their basis, such as spot and forward rates.

[2] Based on the quoted price of publicly traded mutual funds which are classified as trading securities and accounted for using the mark-to-market method.

[3] Measured as the present value of all expected future cash flows based on the LIBOR-based swap yield curves as of March 31, 2020.  The present value calculation uses discount rates that have been adjusted to reflect the credit quality of the Company and its counterparties.
