Financial interest income from loans and credits primarily include a non-monetary financial income of $3.8 million resulting from the refinancing of the debt of Cadonal in the second quarter of 2020 (Note 15).

Financial interest income from loans and credits in 2018 primarily included a non-monetary financial income of $36.6 million resulting from the refinancing of the debts of Helios 1&2 and Helioenergy 1&2 in the second quarter of 2018.

Interests from other debts are primarily interests on the notes issued by ATS, ATN, Solaben Luxembourg, Hypesol Solar Inversiones and Atlantica Sustainable Infrastructure Jersey, and interests related to the investment from Liberty (Note 16). The decrease in 2020 is primarily due to the acquisition of Liberty’s equity interest in Solana in August 2020. The decrease in 2019 was primarily due to a lower increase of the amortized cost of the Liberty debt compared to the previous year.

Losses from interest rate derivatives designated as cash flow hedges correspond primarily to transfers from equity to financial expense when the hedged item is impacting the consolidated income statement.

Net exchange differences

Net exchange differences primarily correspond to realized and unrealized exchange gains and losses on transactions in foreign currencies as part of the normal course of the business of the Company.
