                         CHAPTER 227--SENTENCES
 
                       SUBCHAPTER D--IMPRISONMENT
 
Sec. 3584. Multiple sentences of imprisonment

    (a) Imposition of Concurrent or Consecutive Terms.--If multiple 
terms of imprisonment are imposed on a defendant at the same time, or if 
a term of imprisonment is imposed on a defendant who is already subject 
to an undischarged term of imprisonment, the terms may run concurrently 
or consecutively, except that the terms may not run consecutively for an 
attempt and for another offense that was the sole objective of the 
attempt. Multiple terms of imprisonment imposed at the same time run 
concurrently unless the court orders or the statute mandates that the 
terms are to run consecutively. Multiple terms of imprisonment imposed 
at different times run consecutively unless the court orders that the 
terms are to run concurrently.
    (b) Factors To Be Considered in Imposing Concurrent or Consecutive 
Terms.--The court, in determining whether the terms imposed are to be 
ordered to run concurrently or consecutively, shall consider, as to each 
offense for which a term of imprisonment is being imposed, the factors 
set forth in section 3553(a).
    (c) Treatment of Multiple Sentence as an Aggregate.--Multiple terms 
of imprisonment ordered to run consecutively or concurrently shall be 
treated for administrative purposes as a single, aggregate term of 
imprisonment.
