Grants income mainly relate to ITC cash grants and implicit grants recorded for accounting purposes in relation to the FFB loans with interest rates below market rates in Solana and Mojave projects (See Note 16).

Residual increase in other operating income relates primarily to insurance proceeds from claims in some assets of the Company.

The Company changed the presentation of “Other operating expenses” in 2016 to better reflect the nature of its business and costs. Prior years amounts have been reclassified to conform to the new classification presented in the table above.
