⁽¹⁾	Restricted cash consists of deposits restricted under agency agreements and cash restricted by law and other obligations.

⁽²⁾	Money market funds are valued at the closing price reported by the fund sponsor.

⁽³⁾	Fair values of quoted investments are based on current bid prices as of the balance sheet dates.

⁽⁴⁾	The fair value of interest rate swaps is calculated by discounting the estimated future cash flows based on the applicable observable yield curves. See Note 7, Financial Instruments for additional information.

⁽⁵⁾	The fair value of basis swaps and forward currency contracts is estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates.
