Zusammenfassung
Recently, Guica, Huang, Li, and Strominger considered an R^2 correction to
the entropy of a black ring, and found a mismatch between supergravity and the
CFT. However, such a comparison should take into account the subtle distinction
between the asymptotic charges of the black ring and the charges entering the
CFT description. We show that using the correct charges yields perfect
agreement.
