The interest rate in effect as of January 31, 2016 was an annual nominal rate of -0.30%.

This equates to 286,034,410 USD (which includes USD redemptions payable). For the year ended October 31, 2015, there were euro principal deposits of 1,120,840,498, euro principal redemptions of 958,699,359 and euro withdrawals (to pay expenses) of 1,268,329, resulting in an ending euro principal balance of 323,520,521. This equates to 357,376,987 USD. Net interest, if any, associated with creation and redemption activity is held in a euro-denominated non-interest-bearing account, and any balance is distributed in full as part of the monthly income distributions, if any.

- Definition

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
