MEMORANDUM

Premier Pools Management Corp. (“Premier”) appeals the district court’s grant of summary judgment in favor of Colony Insurance Co. (“Colony”). We have jurisdiction pursuant to 28 U.S.C. § 1291 , and we reverse. Because the parties are familiar with the facts and the procedural history, we need not recount it here.

Under California insurance law, the insurer’s duty to defend an insured is broader than its duty to indemnify. An insurer must defend its insured even against suits which could only potentially give rise to damages within the insured’s policy. Horace Mann Ins. Co. v. Barbara B., 4 Cal.4th 1076 , 17 Cal.Rptr.2d 210 , 846 P.2d 792, 795 (1993) (in bank), as modified on denial of reh’g (May 13, 1993).

The district' court erred in granting Colony summary judgment. The Declarations Certificates were ambiguous on their face as to which entity or entities were insured under the policies. The Declarations Certificates list “DP Aquatics Iric. dba Premier Pool Spas & Patio” as the “Client Name.” But the Common Policy Declarations list the “Named Insured” as “Artisan Contractors Association of America,” who neither party argues is the insured. An insurance policy is ambiguous “if it is susceptible of more than one reasonable interpretation in the context of the policy as a whole.” Am. Alternative Ins. Corp. v. Superior Court, 135 Cal.App.4th 1239 , 37 Cal.Rptr.3d 918, 923 (Ct.App.2006). The policy should be interpreted as a “layman would read it and not as it might be analyzed by an attorney or an insurance expert.” E.M.M.I. Inc. v. Zurich Am. Ins. Co., 32 Cal.4th 465 , 9 Cal.Rptr,3d 701, 84 P.3d 385, 390 (2004) (internal quotation marks omitted).

Because the Declarations Certificates were facially ambiguous, the district court should have considered extrinsic evidence. See Montrose Chem. Corp. v. Admiral Ins. Co., 10 Cal.4th 645 , 42 Cal.Rptr.2d 324 , 913 P.2d 878 , 888 (1995) (in bank). When the extrinsic evidence is considered, Premier sufficiently established that it was an insured so as to trigger a duty to defend under California law. See Ameron Int’l Corp. v. Ins. Co. of Pa., 50 Cal.4th 1370 , 118 Cal.Rptr.3d 95 , 242 P.3d 1020 , 1024 (2010). The gross receipts estimate used to calculate premiums included Premier Pools Management Corp.’s receipts, the insurance application lists Premier Pools Management Corp. as the entity responsible for payment, Premier Pools Management Corp. paid the premiums, and Colony defended Premier Pools Management Corp. in a previous lawsuit pursuant to the same policies at issue here. Thus, because there was potential coverage for the underlying suit, Colony had a duty to defend it.

Colony raises other coverage defenses. However, the district court confined its decision to the Declarations Certificates. We decline to consider the additional coverage issues for the first time on appeal, leaving those issues for the district court on remand to consider in the first instance.

REVERSED and REMANDED.

This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3. . In addition, when determining whether an ambiguity exists under California law, a court should consider not just the face of the contract but also whether offered extrinsic evidence "is relevant to prove a meaning to which the language of the instrument is reasonably susceptible.” Dore v. Arnold Worldwide, Inc., 39 Cal.4th 384 , 46 Cal.Rptr.3d 668 , 139 P.3d 56, 60 (2006) (quoting Pac. Gas & Elec. Co. v. G.W. Thomas Drayage & Rigging Co., 69 Cal.2d 33 , 69 Cal.Rptr. 561 , 442 P.2d 641, 644 (1968)). Thus, the district court should have considered the extrinsic evidence in any event.
