What is the standard of review for a district court's handling of discovery?

The district court did not abuse its discretion in its handling of discovery. See Preminger v. Peake, 552 F.3d 757, 768, n.10 (9th Cir. 2008) (setting forth standard of review for district court's decisions concerning the scope of discovery).

We do not consider matters not specifically and distinctly raised and argued in the opening brief, or arguments and allegations raised for the first time on appeal. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).
