II (“L.P.II”) (collectively, the “Funds”), each of which is a private investment limited partnership, and the investment manager to a limited number of separate managed accounts (each a “Managed Account” and collectively the “Managed Accounts”).  Douglas Granat, Lawrence A. Oberman, Steven G. Simon and Bradley F. Simon are the controlling shareholders and/or sole directors of Trigran Investments, Inc. and thus may be considered the beneficial owners of the Common Stock beneficially owned by Trigran Investments, Inc.  Each of the Reporting Persons disclaims beneficial ownership of the Common Stock except to the extent of its pecuniary interest therein.

(d)-(e)  None of the Reporting Persons have (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors); or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction where 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.

Item 3.   Source and Amount of Funds or Other Consideration

Funds for the purchase of the Common Stock were derived from the working investment capital of the Funds and the Managed Accounts. A total of $711,275.27 was paid to acquire the Common Stock purchased on May 23, 2013, as follows: Trigran Investments, L.P. acquired 8,483 shares of Common Stock at a total cost of $434,119.13; Trigran Investments, L.P. II acquired 4,917 shares of Common Stock at a total cost of $251,641.14 and the Managed Accounts acquired 500 shares of Common Stock at a total

cost of $25,515.00.

A total of $14,515,839.34 was paid to acquire all of the shares of Common Stock reported herein (including the shares acquired on May 23, 2013) as follows: Trigran Investments, L.P. acquired 248,302 shares of Common Stock at a total cost of $8,712,471.51; Trigran Investments, L.P. II acquired 144,415 shares of Common Stock at a total cost of $5,124,714.71 and the Managed Accounts acquired 13,926 shares of Common Stock at a total cost of $678,653.12.

The Common Stock was acquired in the ordinary course of the Funds’ and Managed Accounts’ business and is held by each of the foregoing in separate accounts maintained for each of them by their respective prime brokers.  While the Funds’ and Managed Accounts’ agreements with their respective prime brokers permit such prime brokers to extend margin credit to the Funds and Managed Accounts as and when required to open or carry positions in the accounts, subject to applicable federal margin regulations, stock exchange rules and the prime broker’s credit policies, none of the Funds or Managed Accounts purchased any of the shares of Common Stock on margin.

Item 4. Purpose of Transaction

The Common Stock has been acquired for investment in the ordinary course of the Reporting Persons’ investment activities and has not been acquired with any purpose of, or with the effect of, changing or influencing the control of the Issuer, or in connection with or as a participant in any transaction having that purpose or effect.  Reporting Persons Trigran Investments, Inc., Douglas Granat, Lawrence A. Oberman and Steven G. Simon have previously filed Schedules 13G with regard to their holdings of securities of the Issuer.

The Reporting Persons have been patient shareholders of the Issuer for almost six years and have generally been pleased with management’s ability to control expenses and generate substantial free cash flow. However, as the amount of cash on the Issuer’s balance sheet has grown significantly over time without the Issuer engaging in any type of capital allocation program for the benefit of shareholders, the Reporting Persons have become increasingly frustrated with the current Board of Directors due to their lack of action.  The Reporting Persons have had general discussions with the Issuer’s Chief Executive Officer about the Issuer’s lack of a capital allocation strategy on numerous occasions over the recent past; however, recent attempts to discuss the topic with the Board of Directors have been met with resistance.  The Reporting Persons believe the Issuer’s current cash balance is well in excess of what is needed to run the business and have recently attempted to convey this to the Board of Directors.  The Reporting Persons would like to have an open discussion with members of the Board of Directors about the best method to deploy the Issuer’s excess cash to increase shareholder value.  The Reporting Persons also might seek to engage in discussions with other shareholders of the Issuer regarding a capital allocation strategy that will best benefit the shareholders of the Issuer.

Notwithstanding the foregoing, the Reporting Persons currently continue to hold the Common Stock for investment in the ordinary course of their investment activities and have not acquired and do not hold the Common Stock with any purpose of, or with the effect of, acquiring, changing or influencing the control of the Issuer, or in connection with or as a participant in any transaction having that purpose or effect.  However, out of an abundance of caution, the Reporting Persons have determined it to be appropriate to file this report on Schedule 13D.  The Reporting Persons may in the future determine to purchase more Common Stock and/or dispose of Common Stock in the ordinary course of their investment activities, as market and other conditions dictate.

Item 5.   Interest in Securities of the Issuer

(a)-(b)  Incorporated by reference to Items (7) - (11) and (13) of the cover page relating to each Reporting Person.

* This transaction was for Reporting Person Trigran Investments, L.P.

(d)           Owners of certain Managed Accounts have or may have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, securities of the Issuer held in those accounts. No such account has such power with respect to more than five percent of the class of securities to which this Schedule 13D relates.
