Unless otherwise indicated, all capitalized terms used herein shall have the meanings given to them in the Schedule 13D, and unless amended or supplemented hereby, all information previously filed remains in effect.

Item 2 of the Schedule 13D is hereby amended and restated in its entirety as follows:

“(a) - (f) This Statement is filed jointly by: (i) PGP, (ii) Prescott Associates, (iii) PIPS, (iv) Thomas W. Smith and (v) Scott J. Vassalluzzo (the persons and entities in (i) through (v) are referred to collectively herein as the “Reporting Persons”). The filing of this Statement shall not be deemed to be an admission that the Reporting Persons comprise a “group” within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended. The Reporting Persons each disclaim beneficial ownership of the shares reported in this Statement in excess of those shares as to which they have or share voting or investment authority.

Each of Messrs. Smith and Vassalluzzo is a private investment manager, a managing member of PGP, and a trustee of PIPS. The business address of each of the Reporting Persons is 2200 Butts Road, Suite 320, Boca Raton, FL 33431.

During the last five years, no Reporting Person has been convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) nor has any Reporting Person been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

PGP is a Delaware limited liability company. Prescott Associates is a New York limited partnership. PIPS is an employee profit-sharing plan organized under the laws of the State of Delaware. Each of Messrs. Smith and Vassalluzzo is a citizen of the United States.”

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Schedule 13D is hereby amended and restated in its entirety as follows:

“In order to fund the purchase of the Common Stock reported herein, the Managed Accounts (as hereinafter defined) contributed in the aggregate $28,009,781.45 of the funds of the Managed Accounts (including $15,381,416.71 contributed by Prescott Associates and $804,498.33 contributed by PIPS), Mr. Vassalluzzo contributed $990,322.17 of his personal funds and Mr. Smith contributed $10,697,425.34 of his personal funds. The Common Stock reported as beneficially owned by Mr. Vassalluzzo includes the following received by him for his service as a director of the Issuer: (i) 4,000 vested restricted stock units (“RSUs”) granted under the Issuer’s Amended and Restated Incentive Compensation Plan dated March 26, 2012 (the “2012 Incentive Plan”) and (ii) 9,125 shares of Common Stock received as payment for an equivalent number of vested RSUs granted under the Issuer’s Amended and Restated Incentive Compensation Plan dated April 6, 2009 (the “2009 Incentive Plan”).”

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and restated in its entirety as follows:

As described more fully in Item 5 below, as general partner of the Partnerships, PGP may be deemed to beneficially own 2,116,840 shares of Common Stock held by the Partnerships. PIPS may be deemed to beneficially own 76,963 shares of Common Stock held on behalf of the employee profit-sharing plan participants. Messrs. Smith and Vassalluzzo may be deemed to beneficially own 100,048 and 2,758 shares of Common Stock, respectively, in their capacities as investment managers for several managed accounts, which consist of investment accounts for: (i) a private charitable foundation established by Mr. Smith and for which Mr. Smith acts as trustee (the “Foundation”) and (ii) certain family members of Mr. Vassalluzzo and certain individual accounts managed by Mr. Smith. The Partnerships, PIPS and the managed accounts are referred to collectively herein as the “Managed Accounts.” The 2,296,609 shares of Common Stock owned by the Managed Accounts (the “Managed Account Shares”) were acquired by the Reporting Persons on behalf of the Managed Accounts for the purpose of achieving the investment goals of the Managed Accounts.

Mr. Vassalluzzo currently serves as a director of the Issuer and may be deemed to beneficially own 64,125 shares of Common Stock for his own account, including 51,000 shares of Common Stock acquired for investment purposes, 4,000 vested RSUs awarded under the 2012 Incentive Plan and 9,125 shares of Common Stock received for vested RSUs awarded under the 2009 Incentive Plan.

In addition, Mr. Smith may be deemed to beneficially own 670,397 shares held by Ridgeview Smith Investments LLC, a limited liability company established by Mr. Smith, the sole member of which is a revocable trust established by Mr. Smith for the benefit of his family (the “Ridgeview Shares”). Mr. Smith acquired the Ridgeview Shares for investment purposes.

On December 10, 2019, PIPS and each of the Partnerships entered into separate pre-arranged stock trading plans with Fidelity Brokerage Services LLC (“Fidelity”) designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, and the Issuer’s insider trading policies (each, a “10b5-1 Plan”). The description of the 10b5-1 Plans set forth in Item 6 below is incorporated herein by reference in its entirety.

PIPS and the Partnerships are selling Common Stock of the Issuer pursuant to the Rule 10b5-1 Plans for portfolio management purposes only. These Reporting Persons continue to believe that the Issuer remains an attractive long-term investment.

Subject to the agreements described above, depending upon market conditions, the availability of funds, an evaluation of alternative investments, and such other factors as may be considered relevant, each of the Reporting Persons may purchase or sell shares of Common Stock if deemed appropriate and opportunities to do so are available, in each case, on such terms and at such times as such Reporting Person considers desirable. The Reporting Persons may talk or hold discussions with various parties, including, but not limited to, the Issuer’s management, its board of directors, and other shareholders and third parties, for the purpose of developing and implementing strategies to maximize shareholder value, including strategies that may, in the future, result in the occurrence of one or more of the actions or events enumerated in clauses (a) through (j) of Item 4 of Schedule 13D.

Subject to the foregoing, none of the Reporting Persons has any present plan or proposal which relates to or would result in any of the actions or events enumerated in clauses (a) through (j) of Item 4 of Schedule 13D. In addition, each Reporting Person disclaims any obligation to report any plan or proposal known to such Reporting Person solely as a result of Mr. Vassalluzzo’s position as a director of the Issuer and his participation in such capacity in decisions involving an action or event described in clauses (a) through (j) in Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

Paragraphs (a), (b) and (c) of Item 5 of the Schedule 13D are hereby amended and restated as follows:

(a)       Based on information included in the current report on Form 10-Q filed by the Issuer on November 1, 2019, which disclosed that 18,796,754 shares of Common Stock were outstanding as of October 22, 2019, the aggregate number and percentage of shares of Common Stock beneficially owned by each of the Reporting Persons is as follows: PGP – 2,116,840 shares (11.3%); Prescott Associates – 1,372,729 shares (7.3%); PIPS – 76,963 shares (0.4%); Mr. Smith – 770,445 shares (4.1%); and Mr. Vassalluzzo – 66,883 shares (0.4%).

(b)       PGP, as the general partner of the Partnerships, may be deemed to share the power to vote or to direct the vote and to dispose or to direct the disposition of 2,116,840 shares of Common Stock. Prescott Associates has the shared power to vote or to direct the vote and to dispose or to direct the disposition of 1,372,729 shares of Common Stock. PIPS has the sole power to vote or to direct the vote of and to dispose or to direct the disposition of 76,963 shares of Common Stock. Messrs. Smith and Vassalluzzo have the sole power to vote or to direct the vote of and to dispose or to direct the disposition of 684,345 and 66,883 shares, respectively. In their capacities as investment managers for Managed Accounts, Messrs. Smith and Vassalluzzo may be deemed to share the power to vote or to direct the vote of and to dispose or to direct the disposition of 86,100 and no shares of Common Stock, respectively. Voting and investment authority over investment accounts established for the benefit of certain family members and friends of Messrs. Smith and Vassalluzzo is subject to each beneficiary’s right, if so provided, to terminate or otherwise direct the disposition of the investment account.

(c)       During the sixty (60) days prior to the date of this filing, the Reporting Persons effected no transactions involving shares of Common Stock except the following:

Date	Nature of Transaction	Reporting Person(s)	Number of Shares	Price Per Share

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 of the Schedule 13D is hereby amended and restated in its entirety as follows:

“Pursuant to the 10b5-1 Plans, Fidelity may sell up to 500,000 shares of Common Stock beneficially owned by PIPS and the Partnerships, including (i) 20,000 shares beneficially owned by PIPS and (ii) 295,000 shares beneficially owned by Prescott Associates. All sales are to be executed in the discretion of Fidelity in accordance with the terms of the applicable 10b5-1 Plan, including price, volume and other conditions. Sales under each 10b5-1 Plan may commence beginning January 2, 2020 and will continue until the earlier of the date on which all shares of Common Stock to be sold under the 10b5-1 Plan have been sold, the 10b5-1 Plan is terminated in accordance with its terms, or December 31, 2020.

Mr. Vassalluzzo currently serves as a director of the Issuer. Under the Issuer’s 2012 Incentive Plan, non-employee directors are eligible to receive incentive compensation in the form of RSU awards. Each RSU represents and has a value equal to one share of the Issuer’s common stock. The RSUs will vest over a five-year period starting in 2014 based upon the compounded annual growth rate in the Issuer’s adjusted economic profit. Vested RSUs will be distributed on February 22, 2021. As of the date hereof, Mr. Vassalluzzo has 4,000 vested RSUs under the Issuer’s 2012 Incentive Plan. The foregoing description of the 2012 Incentive Plan is qualified in its entirety by reference to the 2012 Incentive Plan, a copy of which is filed as Exhibit 2 and incorporated herein by reference.

With respect to any Managed Account established for the benefit of family members or friends of a Reporting Person, the voting and investment authority accorded the Reporting Person is subject to each beneficiary’s ability, if so provided, to terminate or otherwise direct the disposition of the Managed Account. Subject to the foregoing, and except as otherwise set forth in Item 4 above, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among any of the Reporting Persons and any other person with respect to any securities of the Issuer, including any contract, arrangement, understanding or relationship concerning the transfer or the voting of any securities of the Issuer, or any finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.”
