Where a defendant is sentenced to concurrent terms, only one of which is for a violent felony, section 2933.1 limits his ability to earn conduct credits only for the duration of the term for the violent felony. The defendant here was sentenced to a five-year term for a violent offense, and a concurrent ten-year term for a nonviolent offense. The court held that while the conduct credits for each offense were limited to fifteen percent until the end of the term for the violent offense, once that term had been served the credit limitation ended. This construction would not apply to consecutive terms, since section 1170.1 provides that consecutive terms are treated as a single aggregate term.
