Note 1 – Organization

Invesco DB G10 Currency Harvest Fund (the “Fund”) was formed as a Delaware statutory trust on April 12, 2006. The term of the Fund is perpetual (unless terminated earlier in certain circumstances) as provided for in the Fifth Amended and Restated Declaration of Trust and Trust Agreement of the Fund, as amended (the “Trust Agreement”). The Fund has an unlimited number of shares authorized for issuance.

Invesco Capital Management LLC (“Invesco”) has served as the managing owner (the “Managing Owner”), commodity pool operator and commodity trading advisor of the Fund since February 23, 2015. The Managing Owner holds 40 general shares (the “General Shares”) of the Fund. The fiscal year end of the Fund is December 31st.

The Fund seeks to track changes, whether positive or negative, in the level of the Deutsche Bank G10 Currency Future Harvest Index–Excess Return™ (the “Index”) over time, plus the excess, if any, of the sum of the Fund’s interest income from its holdings of United States Treasury Obligations (“Treasury Income”), dividends from its holdings in money market mutual funds (affiliated or otherwise) (“Money Market Income”) and dividends or distributions of capital gains from its holdings of T-Bill ETFs (as defined below) (“T-Bill ETF Income”) over the expenses of the Fund. The Fund invests in futures contracts in an attempt to track its Index. The Index is designed to reflect the performance of certain currencies. The currencies comprising the Index, at any time (each an “Index Currency”, and collectively, the “Index Currencies”), are six of the following Group of Ten currencies: United States Dollars, Euros, Japanese Yen, Canadian Dollars, Swiss Francs, British Pounds, Australian Dollars, New Zealand Dollars, Norwegian Krone and Swedish Krona (collectively, the “Eligible Index Currencies”). At any time, the Index will consist of long futures contracts on the three Eligible Index Currencies associated with the highest interest rates and short futures contracts on the three Eligible Index Currencies associated with the lowest interest rates.
