This case consolidates two appeals, by the Hanover Insurance Co. (“Hanover”) and Ray Shipes, respectively, from the district court’s order (1) entering summary judgment for Shipes on his claim against Hanover for certain no-fault motor vehicle personal injury protection (“PIP”) insurance benefits, and (2) entering summary judgment for Hanover on Shipes’s claim for additional damages against Hanover based on Hanover’s alleged lack of good faith in denying the disputed benefits. We affirm on both issues.
I. STATEMENT OF THE CASE
Shipes, an employee of Macon Mine and Mill Co. (“Macon”), was injured while driving a company vehicle on October 10, 1985, resulting in the loss of his weekly wages of $224.67. In addition to workers’ compensation benefits, Macon provided PIP benefits through a policy with Hanover. Following the accident, Shipes received $149.78 in weekly workers’ compensation, leaving weekly lost wages of $74.89. Of that amount, Hanover paid Shipes 85%, or $63.66, in PIP benefits. This left Shipes with an overall weekly shortfall of $11.23 in lost wages. On April 17, 1986, Shipes’s attorney, invoking his interpretation of O.C.G.A. § 33-34-8(c) (1982), wrote Hanover’s claims representative, Emita Hyman, to demand that Shipes’s benefits be adjusted upward by $11.23 weekly, so as to compensate him for the entire amount of lost wages. Hyman responded on May 1, 1986, asserting the correctness of Hanover’s coordination of Shipes’s benefits based on Hanover’s interpretation of section 33-34-8(c). Shipes’s benefits, as calculated by Hanover, continued until November 24, 1986, for a total of 58 weeks. The only dispute between the parties concerns the proper coordination, under Georgia law, of Shipes’s workers’ compensation and PIP benefits, and Hanover’s good faith or lack thereof in following its chosen coordination of benefits.
Shipes brought suit against Hanover in Georgia state court, and Hanover removed to the district court on diversity grounds.

On September 30, 1987, the district court granted summary judgment for Shipes on the benefits issue.

II. DISCUSSION
We note at the outset that a grant of summary judgment is subject to
de novo
review.
Carlin Communication, Inc. v. Southern Bell Tel. & Tel. Co.,
A. The Benefits Issue
PIP benefits themselves are governed by O.C.G.A. §§ 33-34-4 and 33-34-5 (1982 & Supp.1989). 3 Those sections are silent, however, on how to coordinate PIP benefits with workers’ compensation. That issue is governed solely by section 33-34-8(c), which provides that PIP benefits will be reduced or eliminated to the extent a worker receives workers’ compensation,
provided that in no event shall the aggregate amount of benefits which the insured injured person is entitled to receive as compensation for the loss of income or earnings during disability under this chapter without regard to fault [i.e., under a PIP benefits plan] and under any workers’ compensation law be less than an amount which is equal to the person’s loss of income or earnings during disability or an amount which is equal to the amount the person is entitled to receive as compensation for the loss under any workers’ compensation law plus the limits of the coverage under any applicable policy of motor vehicle insurance or under any program of self-insurance providing such benefits, whichever is less. [Emphasis added.]
Although the language is convoluted, it clearly indicates that PIP benefits can be reduced by the amount of workers’ compensation only to the extent necessary to prevent the total benefits from running higher than the worker’s total lost wages. The worker’s total benefits cannot fall below either (1) the amount of lost wages, or (2) the sum of the workers’ compensation benefits plus the maximum PIP coverage, *1360 whichever is less. This means that Shipes’s total benefits could not fall below the lesser of (1) his weekly lost wages of $224.67, or (2) $340.75. 4
The district court, in adopting this interpretation of the statute, relied on its plain language and noted a 1980 Georgia Attorney General Opinion precisely on point.
5
Hanover’s contrary position is based on dicta contained in two Georgia cases.
Brown v. Boston Old Colony Ins. Co.,
In neither
Brown
nor
Sharpton
was the coordination of benefits at issue, however, apparently because the workers in those cases did not challenge the insurer’s coordination. Each case decided a completely separate issue. We therefore agree with the district court that
Brown
and
Sharp-ton
do not justify departing from the plain meaning of section 33-34-8(c). While Attorney General Opinions are not regarded as binding authority in Georgia,
see Williams v. State,
B. The Good Faith Issue
Under O.C.G.A. §§ 33-34-6(b) and (c) (1982), when an insurer refuses to pay benefits to which an insured is entitled within certain time limits, it becomes liable for penalties, attorneys’ fees, and punitive damages, unless it can prove that its refusal was in good faith.
7
Hanover concedes that it refused to pay the additional amount of PIP benefits claimed by Shipes within the applicable time limits. The only issue is whether, construing the record in Shipes’s favor and taking into account his Rule 56(f) affidavit, any genuine issue of material fact exists as to Hanover’s good faith.
See
Fed.Rule Civ.P. 56(c);
Celotex Corp. v. Catrett,
An insurer acts in good faith if it has “reasonable” cause for nonpayment of a disputed claim.
See International Indemnity Co. v. Collins,
In this case, there are no disputed factual issues regarding Shipes’s entitlement to PIP benefits.
9
The sole issue is the correct interpretation of the governing statute. Hanover’s legal argument on that point, while ultimately unpersuasive, is not “frivolous” or “unfounded.” There is still no authoritative Georgia precedent on point. Despite the somewhat convoluted language of the statute, dicta in two eases, including one from the Georgia Supreme Court, appear to assume a different method of calculation.
10
Hanover notes that of. the two methods described in the facts of
Brown
and
Sharpton,
it chose the more generous method in
Brown
in calculating Shipes’s benefits. Hanover was “legally justified in litigating the issue.”
See Collins,
Shipes argues that the district court, in granting summary judgment, improperly considered the credibility of an affidavit from Hanover’s claims representative, Emi-ta Hyman, asserting that Hanover “acted in good faith and relied upon [its] interpretation of O.C.G.A. § 33-34-8(c)” in calculating Shipes’s benefits.
Cf. Carlin Communication, Inc. v. Southern Bell Tel. & Tel. Co.,
Shipes also argues that summary judgment was improper in the face of his Rule 56(f) affidavit and pending motion to compel. The cases on which he relies are readi *1362 ly distinguishable. 12 Under the Georgia law of good faith, the further evidence sought by Shipes was simply immaterial The district court correctly granted summary judgment on the basis of the record before it, on the ground that Hanover had established its good faith as a matter of law.
III. CONCLUSION
For the reasons stated, the judgment of the district court is AFFIRMED in aH respects.
Notes
. The court awarded Shipes $651.34 (58 times $11.23) plus 7% annual interest pursuant to O.C.G.A. § 7-4-2.
. On July 11, 1988, the district court issued an unpublished final order entering the foregoing judgments, and denied as moot Shipes’s intervening amended-complaint and discovery motions. On appeal, the parties devote some attention in their briefs to arguing the merits and timeliness of Shipes’s amended-complaint motion. Because we affirm the grant of summary judgment on the good faith issue, which terminated the case, we agree with the district court’s disposition of Shipes’s motion and find it unnecessary to discuss its merits.
.Section 33-34-4 describes the minimum benefits required by law. Section 33-34-5 describes optional additional benefits. Under both the minimum and optional coverages, PIP benefits alone may not exceed 85% of the income lost due to injury. The policy held by Macon under which Shipes received benefits provided minimum coverage, but with a higher total payout limit of $50,000. Under that policy, Shipes was entitled to receive PIP benefits constituting 85% of his lost weekly wages, up to a weekly maximum of $200. Since Shipes made $224.67 a week, his maximum weekly PIP coverage was $190.97.
. The figure of $340.75 is obtained by adding Shipes’s $149.78 weekly workers' compensation to his maximum weekly PIP coverage of $190.97. See footnote 3, supra.
. See 1980 Ga. Att’y Gen.Op. 129 (No. 80-61). The opinion adopts the reading urged by Shipes in this case and provides a numerical example strikingly similar to the facts of this case. See id. at 131.
. It makes an obvious difference whether the amount of workers’ compensation is subtracted before or after the 85% multiplier is applied. The insurer in Brown first subtracted workers’ compensation from the total lost wages, then gave the worker 85% of the difference. The insurer in Sharpton was much less generous, first calculating 85% of the total lost wages, and then subtracting workers’ compensation from that. Under the Sharpton facts, Shipes would have received only $41.19 a week in PIP benefits (85% of $224.67, or $190.97, minus $149.78), leaving him with a weekly shortfall of $33.70 instead of $11.23.
.Under section 33-34-6(b), an insurer becomes potentially liable for attorneys’ fees and "bad faith” penalties after 30 days from the time the insured supplies “reasonable proof’ of the claim. Under section 33-34-6(c), an insurer becomes potentially liable for punitive damages after 60 days from the time of claim.
See Binns v. MARTA,
. In view of
Collins,
Shipes’s reliance on earlier Georgia cases which suggested that good faith is always a question for the jury is unavailing.
See, e.g., Binns v. MARTA,
.
Cf. Insurance Co. of North America v. Smith,
. This distinguishes the instant case from
Mowery,
. The record indicates that Shipes's attorney and Hyman spoke by telephone regarding their respective interpretations of section 33-34-8(c) on February 6 and 10, 1986. The April 17, 1986 letter from Shipes’s attorney was the first written demand for the disputed benefits, however.
