For all of its restricted investments and bond collateral accounts, the Company can select from limited fixed-income investment options for the funds and receive the investment returns on these investments. Funds in the restricted investments and bond collateral accounts are not available to meet the Company’s general cash needs. Net proceeds from the New Notes (see Note 4) are held in escrow pending the completion of the Sherritt Acquisition and are held entirely in cash. Other requirements for the Sherritt Acquisition include cash required to be deposited in a restricted account for interest accrued as of March 31, 2014 for the New Notes and other fees expected to be paid in connection with the Sherritt Acquisition.

These accounts include held-to-maturity securities. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts calculated on the effective interest method. Interest income is recognized when earned.
