We consolidated these appeals because they turn on a common issue — namely, the proper method for calculating accrued dividends on shares of preferred stock issued by Defendant, Archon Corporation. Plaintiffs are investment groups that acquired Archon stock before it was redeemed in 2007. They dispute Defendant’s calculation of the redemption price of their shares, a substantial portion of which consists of accrued dividends.

We review de novo a district court’s summary judgment ruling. Ferguson ex rel. McLeod v. Coregis Ins. Co., 527 F.3d 930, 932 (9th Cir.2008) (per curiam). “[(Questions of state law are reviewable under the same independent de novo standard as are questions of federal law.” In re Complaint of McLinn, 739 F.2d 1395, 1397 (9th Cir.1984) (en banc). In this diversity case, we apply Nevada law. See Goldberg v. Pac. Indem. Co., 627 F.3d 752, 755 (9th Cir.2010).

The district court’s calculation of the damages is correct as a matter of law. Section 7 is the applicable portion of the Certifícate. It clearly provides for a cumulatively derived rate per share in arriving at the redemption price of the dividends for preferred stock. Section 2, even if it applied, is consistent with Section 7 and uses the same method of calculation.

The other contemporaneous documents all are consistent with this reading of the Certificate. Later interpretations do not make the Certificate ambiguous. Because the document is complete and unambiguous on its face, summary judgment is appropriate, and no further proceedings are called for. See Ringle v. Bruton, 120 Nev. 82 , 86 P.3d 1032, 1037 (2004).

We decline to decide whether the dividend calculation falls under the statutory definition of “interest” under Nevada Revised Statutes section 99.050. Even as suming that the statute does apply, it permits compound interest when the parties agree to it in writing. Cf. Campbell v. Lake Terrace, Inc., 111 Nev. 1329 , 905 P.2d 163, 165 (1995) (per curiam) (noting that compound interest is allowed when an instrument specifically calls for it), overruled on other grounds by Aviation Ventures, Inc. v. Joan Morris, Inc., 121 Nev. 113 , 110 P.3d 59, 65 (2005). Here, the unambiguous text of the Certificate requires a cumulatively derived rate per share, as calculated by the district court.

AFFIRMED.
