No. 635, 2007.
Supreme Court of Delaware.

Before STEELE, Chief Justice, JACOBS, and RIDGELY, Justices.
RIDGELY, Justice:
Plaintiff-Appellant Hermilo Ramirez filed a Huffman claim[1] seeking liquidated damages, attorneys' fees and costs for the late payment of Worker's Compensation benefits. He appeals the Superior Court's grant of summary judgment in favor of the Defendants-Appellees, Jeremy Murdick, M & A Construction, Inc. and M & A Construction (the "Employer"). The Superior Court determined that the remedies under 19 Del. C. § 2357 did not apply because the default in payment was less than thirty days from when the benefits were due to be paid.
Ramirez makes two arguments on appeal. First, he contends that the Superior Court erred in its interpretation and application of two provisions of the Workers' Compensation Act, specifically 19 Del. C. §§ 2357 and 2362(c). Second, he argues that the Superior Court erred by converting Employer's motion to dismiss into a motion for summary judgment. We find no merit to Ramirez's first argument. We also find that although the Superior Court *397 erred in converting the motion without notice, the error was harmless. Accordingly, we affirm.

I. Facts
The facts are undisputed. While working for Employer as a construction worker, Ramirez was injured. He filed a petition with the Industrial Accident Board seeking payment of workers' compensation benefits. On February 8, 2007, the parties entered into a settlement agreement under which Employer would pay Ramirez total disability benefits and medical expenses. That same day, Ramirez's counsel wrote a letter to Employer's counsel making a Huffman demand that the benefits be paid within thirty days of his letter. The employer mailed payment on March 14, and Ramirez's counsel received the payments on March 16, which occurred thirty-four and thirty-six days after Ramirez made his Huffman demand, respectively.
Ramirez filed a complaint in Superior Court seeking liquidated damages, attorneys' fees and costs under 19 Del. C. § 2357, claiming Employer did not submit payment within thirty days of his Huffman demand. Employer filed a motion to dismiss, contending that it made the payment within thirty days of February 22, 2007; the date payment was due as prescribed by statute. The Superior Court converted the motion to dismiss to a motion for summary judgment since matters outside the pleadings needed to be considered.[2] Based on its interpretation of 19 Del. C. § 2362(c), as it applies to 19 Del. C. § 2357, the court found that Employer defaulted on February 23, the fifteenth day after the February 8 agreement. The court also found that the payment was made within thirty days of the default. Accordingly, the Superior Court granted summary judgment in favor of Employer. This appeal followed.

II. Discussion
Ramirez argues that the Superior Court erred in dismissing his complaint because the thirty-day demand period under 19 Del. C. § 2357[3] runs concurrently with the fourteen-day period for payment under 19 Del. C. § 2362(c).[4] We review the Superior Court's construction of the Workers' Compensation Act de novo.[5]

A.
Civil actions filed under 19 Del. C. § 2357 "to collect unpaid workers' compensation awards have become known as `Huffman' claims"[6] after the case of Huffman v. C.C. Oliphant & Son, Inc.[7] Section 2357 entitles a worker to liquidated damages, attorneys' fees and costs in the event of default by the employer thirty days after demand is made "of any amount due."[8] As we noted in Le Van v. Independence *398 Mall, Inc.,[9] "the focus of the Huffman award must be on the employer's failure to pay once the thirty day default period has expired after proper demand."[10] When an amount is due to a claimant "the date a Huffman demand letter is mailed is sufficient to trigger the statutory period to pay benefits. . . . "[11]
"The goal of statutory construction is to determine and give effect to legislative intent."[12] "If a statute is not reasonably susceptible to different conclusions or interpretations, courts must apply the words as written, unless the result of such a literal application could not have been intended by the legislature."[13] Here, we must determine the intent of the legislature in defining when an amount is due after a settlement agreement.
Section 2362(c) of Title 19 defines when an amount is due to be paid after a settlement agreement. Under this provision, "payment of compensation shall commence within 14 days of the date of that agreement."[14] There is nothing ambiguous about when payment is due under this provision. Because the settlement agreement between the parties was made on February 8, the statute required that payment be made within fourteen days of that agreement. As a matter of law, the amount due date was no later than February 22. A Huffman demand, therefore, for an amount due would be timely and proper after that date. The Employer would be subject to Huffman liability thirty days after that demand.[15]
The record in this case shows that payment was mailed by Employer's counsel on March 14. This was within the thirty day period contemplated by 19 Del. *399 C. § 2357. Because the default was for less than thirty days from the date the amount was due, the remedies under 19 Del. C. § 2357 do not apply. The Superior Court did not err in its interpretation and application of the Workers' Compensation Act.

B.
Next, Ramirez argues that the Superior Court erred in converting his motion to dismiss into a motion for summary judgment. We review rulings on motions to dismiss pursuant to Rule 12(b)(6) and motions for summary judgment de novo.[16]
In Appriva Shareholder Litigation Co. v. EV3, Inc.,[17] we explained that "in reviewing the Superior Court's decision to convert a motion to dismiss into a motion for summary judgment, we will examine three issues: [i] whether the materials submitted required conversion; [ii] whether the parties had adequate notice of the trial court's intention to convert; and [iii] if the parties did not have notice, whether the trial court's failure to provide notice was harmless error."[18] Superior Court Civil Rule 12(b)(6) expressly requires that if matters outside the pleadings are considered, "all parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 56."[19] "An error in converting a Rule 12(b)(6) motion without notice is harmless only where there is `no set of facts on which plaintiffs could possibly recover.'"[20]
The Superior Court converted the motion to one for summary judgment in this case because it was considering matters that were outside of the pleadings.[21] The parties agree that they did not have notice of the Superior Court's intention to convert the motion. The parties also agree, as they did in Superior Court, that the facts pertinent to this litigation are undisputed. This case turned upon the court's application of two statutes to undisputed facts. Although the Superior Court erred in not giving notice of the conversion, this error was harmless because there are no facts on which Ramirez could recover under 19 Del. C. § 2357. Employer's payment was made within thirty days of the amount being due.

III. Conclusion
The judgment of the Superior Court is AFFIRMED.

This fine shall be payable to the Workers' Compensation Fund.").
[15]  The Superior Court correctly noted that a demand letter cannot in and of itself create a default in payment where one has not yet occurred. See Ramirez v. Murdick, 2007 WL 4171117, at *2 (Del.Super.). While the Huffman demand in this case was premature, Ramirez would not have had to make a second, timely Huffman demand. See Delmarva Warehouses, Inc. v. Yoder, 2001 WL 1329691, at *1 (Del.Supr.) ("[I]t would amount to an unreasonable elevation of form over substance to require the employee to reassert his demand in order to trigger the employer's obligation to pay the award."); see also Cunningham, 810 A.2d at 348 (discussing Yoder).
