CORRECTION - NET ASSET VALUE

BLACKROCK COMMODITIES INCOME INVESTMENT TRUST PLC
54930040ALEAVPMMDC31

On the 30th January 2018, the Capital only NAV for BlackRock Commodities Income
Investment Trust plc announced in respect of close of business on 29 January
2018 was understated by 105 basis points due to the fact that undistributed
prior year revenue was not transferred from income to capital as part of the
2017 year-end closedown process (as required when the Company's results were
announced on 29 January 2018).

This oversight occurred due to an error on the part of the Company's
administrator. The corrected NAV as at close of business on 29 January 2018 is
shown below.

The unaudited net asset values for BlackRock Commodities Income Investment
Trust plc at close of business on 29 January 2018 were:

83.61p Capital only
83.91p Including current year income

Notes:

1. Investments have been valued on a bid price basis.

2. Revenue items included in net asset value, with dividends payable deducted
on the ex-dividend date.

3. Following the buyback of 52,000 shares on 12 January 2018, the Company now
