ACX is Amazon’s audiobook publisher.
The current ACX royalties and $25 Bounty program will be changing. Effective for projects started on or after March 12, 2014, titles distributed exclusively to Audible, Amazon, and iTunes will earn a non-escalating 40% royalty paid to the Rights Holder (or, on Royalty Share deals, split equally between the Rights Holder and the Producer). Non-exclusively distributed books will earn a non-escalating 25% royalty through Audible, Amazon, and iTunes.
. . . .
We are lowering the royalties as we continue our mission to accommodate more audiobook productions. Our royalties still remain well above those offered by traditional audiobook publishers. Furthermore, we want to encourage authors, and Rights Holders to promote their audiobooks with the increased bonus payment from $25 to $50 (or from $12.50 to $25.00 on Royalty Share deals).
. . . .
On and after March 12, 2014, only the new royalty structure will be in effect for new projects. However until then, the current royalty structure will be honored for any audiobook offers made before that date that are accepted before the offer expires. In other words, any offers made prior to March 12, 2014 that are accepted before the offer expiration date will earn escalating royalties ranging from 50% to 90% (of unit sales of exclusively distributed titles), or 25% to 70% (of unit sales of non-exclusively distributed titles).
