Terms and conditions for reviewer rewards

Discounts are granted at the Publisher’s discretion, subject to you submitting a timely and detailed report for the article you reviewed.
You can only use one reviewer discount per article, unless alternative arrangements are specified on a journal’s ‘Publication Charges’ information page.
You can use the discount against article processing charges on any IOP-owned journal, not just the journal for which you reviewed.
You can use your reviewer discount for up to two years from the date your report was submitted.
The discount can only be used to pay the open access article publication charge for an article.
Your reviewer discount can only be used for articles on which you are named as an author (you do not have to be the corresponding or first-named author).
Your reviewer discount can only be used on papers accepted after you completed your review.
No cash equivalent is available.
The reviewer discount cannot be used in conjunction with other discounts such as institutional membership schemes.
When reviewers co-review a manuscript together, both reviewers are entitled to a 10% APC discount. The same terms and conditions apply.
