MEMORANDUM *

Defendant-Appellant Government Employees Insurance Company (GEICO) ap*615peals the judgement entered following the district court’s grant of Plaintiff-Appellee Amy J. McDaniel’s motion for summary judgment and denial of GEICO’s cross-motion for summary judgment on McDaniel’s breach of the implied duty to settle third party lawsuits (implied duty to settle) claim. We review both grants and denials of summary judgment de novo. United States v. Washington, 827 F.3d 836, 849 (9th Cir. 2016).

McDaniel is the assignee of an implied duty to settle claim against GEICO. McDaniel alleges that in her underlying wrongful death suit against GEICO’s insured Edward Murotani, GEICO unreasonably refused to accept a $100,000 policy limits settlement offer extended by McDaniel. As a result, the wrongful death suit went to trial, and a California state jury awarded McDaniel over $3 million in judgment against Murotani.

“In each policy of liability insurance, California law implies a covenant of good faith and fair dealing. This implied covenant obligates the insurance company, among other things, to make reasonable efforts to settle a third party’s lawsuit against the insured.” PPG Indus., Inc. v. Transamerica Ins. Co., 20 Cal.4th 310, 312, 84 Cal.Rptr.2d 455, 975 P.2d 652 (1999). Thus, “[w]hen there is great risk of a recovery beyond the policy limits so that the most reasonable manner of disposing of the claim is a settlement which can be made within those limits, a consideration in good faith of the insured’s interest requires the insurer to settle the claim.” Comunale v. Traders & Gen. Ins. Co., 50 Cal.2d 654, 659, 328 P.2d 198 (1958). The implied duty to settle therefore imposes upon the insurer “an obligation to accept a reasonable offer of settlement.” PPG Indus., 20 Cal.4th at 314-15, 84 Cal.Rptr.2d 455, 975 P.2d 652. “An unreasonable refusal to settle may subject the insurer to liability for the entire amount of the judgment rendered against the insured, including any portion in excess of the policy limits.” Hamilton v. Md. Cas. Co., 27 Cal.4th 718, 725, 117 Cal.Rptr.2d 318, 41 P.3d 128 (2002). The insured may assign this cause of action to the third party that obtains a judgment against him. Id. at 732, 117 Cal.Rptr.2d 318, 41 P.3d 128.

A breach of the implied duty to settle claim has two elements. Graciano v. Mercury Gen. Corp., 231 Cal.App.4th 414, 425-26, 179 Cal.Rptr.3d 717 (2014). First, the third party must have “made a reasonable offer to settle the claims against the insured for an amount within the policy limits.” Id. at 425, 179 Cal.Rptr.3d 717. Second, the insurer must have “unreasonably failed to accept an otherwise reasonable offer within the time specified by the third party for acceptance.” Id. at 426, 179 Cal.Rptr.3d 717. Only the second element is at issue in this appeal.

1.' The district court erroneously concluded that an insurer’s negligence is sufficient to breach the implied duty to settle. An insurer breaches the covenant of good faith and fair dealing only when it acts in bad faith, which is defined as “unreasonable” conduct. Brandt v. Superior Court, 37 Cal.3d 813, 819, 210 Cal.Rptr. 211, 693 P.2d 796 (1985) (quoting Austero v. Wash. Nat’l Ins. Co., 132 Cal.App.3d 408, 422, 182 Cal.Rptr. 919 (1982) (Morris, P.J., dissenting)). The critical inquiry for these causes of action is thus the “reasonableness of the insurer’s conduct under the facts of the particular case.” Wilson v. 21st Century Ins. Co., 42 Cal.4th 713, 723, 68 Cal.Rptr.3d 746, 171 P.3d 1082 (2007). While an insurer’s conduct need not rise to the level “of actual dishonesty, fraud, or *616concealment” to constitute bad faith, Crisci v. Sec. Ins. Co. of New Haven, Conn., 66 Cal.2d 425, 430, 58 Cal.Rptr. 13, 426 P.2d 173 (1967), an insurer’s conduct must nevertheless be “prompted not by an honest mistake, bad judgment or negligence but rather by a conscious and deliberate act.” Wilson, 42 Cal.4th at 726, 68 Cal.Rptr.3d 746, 171 P.3d 1082 (quoting Chateau Chamberay Homeowners Ass’n v. Associated Int’l Ins. Co., 90 Cal.App.4th 335, 346, 108 Cal.Rptr.2d 776 (2001)). California courts have recognized that this principle applies in the specific context of implied duty to settle claims. In Palmer v. Fin. Indem. Co., 215 Cal.App.2d 419, 428, 30 Cal.Rptr. 204 (1963), the California Court of Appeal held that “[implied duty to settle] liability is predicated on bad faith, and not upon negligence.” Subsequent California Court of Appeal decisions reaffirm that an insurer’s negligence is insufficient to breach the implied duty to settle. See, e.g., Graciano, 231 Cal.App.4th at 425, 179 Cal.Rptr.3d 717 (“[M]ere errors by an insurer in discharging its obligations to its insured does not necessarily make the insurer liable in tort for violating the covenant of good faith and fair dealing; to be liable in tort, the insurer’s conduct must also have been unreasonable.” (internal quotation marks and emphasis omitted) (quoting Brandt, 37 Cal.3d at 819, 210 Cal.Rptr. 211, 693 P.2d 796)); Walbrook Ins. Co. v. Liberty Mut. Ins. Co., 5 Cal.App.4th 1445, 1460, 7 Cal.Rptr.2d 513 (1992) (noting that an insurer’s “informed rejection [of a settlement offer] is not required to be an infallible one” and “so long as insurers are not subject to a strict liability standard, there is still room for an honest, innocent mistake”). The continued vitality of this rule is further confirmed by McDaniel’s inability to identify a single case in which liability was imposed on an insurer who unintentionally failed to accept a settlement offer.1

2. GEICO is entitled to summary judgment because no reasonable jury could conclude that GEICO unreasonably refused to settle. “[0]rdinarily whether the insurer has acted unreasonably, and hence in bad faith, in rejecting a settlement offer is a question of fact to be determined by the jury.” Walbrook, 5 Cal.App.4th at 1454, 7 Cal.Rptr.2d 513 (internal quotation marks and alteration omitted) (quoting Cain v. State Farm Mut. Auto. Ins. Co., 47 Cal.App.3d 783, 792, 121 Cal.Rptr. 200 (1975)). But the reasonableness of an insurer’s conduct “becomes [a question] of law only when, because there are no conflicting inferences, reasonable minds could not differ.” Id.

The only inference based on undisputed facts is that GEICO’s failure to accept McDaniel’s policy limits settlement offer on or before the September 6, 2009 deadline was caused by negligence. On August 7, 2009, McDaniel’s attorney Steven Nichols extended a $100,000 policy limits settlement offer with a fifteen day acceptance window to GEICO’s attorney Michael Griott. The parties subsequently agreed to extend the acceptance deadline to ten days following McDaniel’s service of responses *617to outstanding interrogatories, which Nichols hand-delivered to Griott on August 27, 2009. On September 1, 2009, Griott emailed GEICO claims adjuster Aldin Buenaventura with a letter attachment indicating that Nichols had submitted the requested interrogatories and, in bold and underlined text, that “[o]ur response to Plaintiffs policy limits demand is due on or before September 11,2009,”2

However, Buenaventura’s contemporaneous emails and notes establish that Bue-naventura did not read Griott’s September 1, 2009 email or the attached letter. Bue-naventura was therefore unaware that the interrogatory answers had been received and deadline to accept the $100,000 settlement had begun to run. For example, in a note entry dated September 4, 2009, Bue-naventura observed that McDaniel’s attorney had granted an extension on his $100,000 settlement demand “until 10 days following responses to discovery,” and he further noted that “the discovery responses are overdue.” And, following a call on September 9, 2009 with Nichols, Buena-ventura described the call in his notes as follows: “I Received Call From P-atty Office * Sw [spoke with] Steve Nichols *.... Our Office Has Not Been Presented With Any Responses To Our Requests To Produce Documentation. Once We Have The Information We Will Then Be Able To Process And Evaluate All Claim. P-atty U/s [understands].” Thus, when Buenaven-tura attempted to accept the settlement offer on October 1, 2009, after receiving authorization from the GEICO home office that same day, he was unaware that the deadline for acceptance had already passed.

In the absence of evidence that establishes that GEICO intentionally allowed the September 6, 2009 deadline to lapse, no reasonable jury could conclude that GEICO’s failure to accept the settlement offer on or before the September 6, 2009 was “a calculated gamble on which only its insured could lose.” Allen v. Allstate Ins. Co., 656 F.2d 487, 490 (9th Cir. 1981). Instead, the facts conclusively establish that GEICO both wanted and attempted to accept McDaniel’s settlement offer, but failed to discover the September 6, 2009 deadline because of Buenaventura’s negligence. But, as discussed above, an insurer’s negligence is insufficient to constitute an “unreasonable refusal” to accept a settlement offer. Accordingly, no reasonable jury could conclude that GEICO unreasonably refused to settle.

Furthermore, there is no theory under which McDaniel can demonstrate that GEICO acted with the requisite degree of culpability to have unreasonably refused to settle. First, although Griott was aware that the settlement deadline began to run on August 27, 2009, constructive or implied knowledge cannot supply the requisite degree of culpability to establish bad faith. See Cal. Shoppers, Inc. v. Royal Globe Ins. Co., 175 Cal.App.3d 1, 37, 221 Cal.Rptr. 171 (1985) (allowing an insurer’s breach of contract to be established by constructive knowledge, but declining to find breach of the implied covenant of good faith and fair dealing in because “there was no direct evidence, including permissible inferences to be drawn therefrom, of a conscious decision on [the insurer]’s part to repudiate its duty to defend [the insured]”). Second, the *618implied duty to settle cannot be breached based on an insurer’s failure “to initiate settlement discussions, or offer its policy limits, as soon as an insured’s liability in excess of policy limits has become clear.” Reid v. Mercury Ins. Co., 220 Cal.App.4th 262, 277, 162 Cal.Rptr.3d 894 (2013). And finally, an insurer who accepts a settlement offer within the time limit imposed by the third party acts in -good faith as a matter of law. See Graciano, 231 Cal.App.4th at 435, 179 Cal.Rptr.3d 717. McDaniel therefore cannot argue that GEICO should have accepted the settlement offer before the deadline that McDaniel herself imposed, or that GEI-CO’s failure to accept the settlement offer before the deadline passed was caused by anything more than negligence.

In sum, we conclude that GEICO is entitled to summary judgment on McDaniel’s breach of the implied duty to settle claim, as no reasonable jury could conclude that GEICO “unreasonably failed to accept” McDaniel’s settlement offer. Accordingly, we reverse the district court’s denial of summary judgment for GEICO, reverse the grant of summary judgment for McDaniel, vacate the judgment, and direct the district court to enter judgment in favor of GEICO.
