PRELIMINARY NOTE

This Amendment No. 4 (this "Amendment") amends and restates in its entirety the Schedule 13D filed by Steven S. Koh with the Federal Deposit Insurance Corporation (the “FDIC”) on December 3, 1998, as amended by Amendment No. 1 and Amendment No. 2 filed with the FDIC on February 18, 2004 and June 4, 2004, respectively, and amendment No. 3 filed with the Securities and Exchange Commission on May 2, 2006 with respect to the common stock, no par value (the "Common Stock"), of Wilshire Bancorp, Inc., a California corporation (the "Issuer" or “Wilshire Bancorp”), and its predecessor and now wholly-owned subsidiary, Wilshire State Bank, a California state-chartered commercial bank (the “Bank”).

ITEM 1. SECURITY AND ISSUER.

The class of equity security to which this statement relates is the Common Stock, no par value, of Wilshire Bancorp, Inc., a California corporation. The name and address of the principal executive offices of the Issuer are 3200 Wilshire Blvd., Los Angeles, California 90010.

The original Schedule 13D filed by Steven S. Koh on December 3, 1998, and Amendment No. 1 and Amendment No. 2 thereto, were filed with the FDIC and reported the Reporting Persons’ (as defined below) ownership of the Common Stock of the Bank. Upon consummation of the reorganization of the Bank into a holding company structure, effective as of August 25, 2004, Wilshire Bancorp succeeded to the business and operations of the Bank. As a result of the reorganization, shareholders of the Bank are now shareholders of Wilshire Bancorp and the Bank is a direct subsidiary of the Company. Pursuant to Rule 12g-3 of the Securities Exchange Act of 1934 (the “Exchange Act”), Wilshire Bancorp succeeded to the reporting obligations of the Bank and the reporting obligations of the Bank to the FDIC have terminated. Filings required to be made by the Reporting Persons under the Exchange Act due to their ownership of Wilshire Bancorp Common Stock, including Amendment No. 3 and this Amendment, are now made with the Securities and Exchange Commission (the “Commission”).

ITEM 2. IDENTITY AND BACKGROUND.

This Statement is being filed jointly by each of the following persons pursuant to Rule 13d-1(k) promulgated by the Commission pursuant to Section 13 of the Exchange Act:

(i) Steven S. Koh, an individual and a United States citizen,

(ii) Jung O. Koh, an individual and a United States citizen,

(iii) Koh-Wilshire, LP, a Nevada limited partnership (the "Partnership"), and

(iv) the Koh Charitable Foundation, a Delaware not-for-profit corporation and a 501(c)(3) tax exempt organization (the "Charitable Foundation")

Steven S. Koh, Jung O. Koh, the Partnership and the Charitable Foundation are referred to herein collectively as the "Reporting Persons." The address of the principal business office of each of the Reporting Persons is 3250 Wilshire Blvd., Suite 2150, Los Angeles, California 90010.

Steven S. Koh's principal employment is as Chairman of Pacific Steel Corporation, a steel import and export business with its principal office located at 3250 Wilshire Blvd., Suite 2150, Los Angeles, California 90010.

Jung O. Koh is a homemaker.

On June 4, 2004, Steven S. Koh and his wife, Jung O. Koh, transferred to the Koh-Wilshire Trust, a revocable trust established under the laws of the State of California (the "Trust”), all of the shares of Bank Common Stock (now Wilshire Bancorp Common Stock) then beneficially owned by them. Mr. and Mrs. Koh (or collectively, the "Kohs") established the Trust under the laws of the State of California on June 4, 2004, pursuant to a Trust Agreement, dated as of June 4, 2004 (the “Trust Agreement”), by and between Steven S. Koh and Jung O. Koh, husband and wife, as Grantors, and Steven S. Koh, as Trustee of the Trust.

SCHEDULE 13D

CUSIP No. 9721862107

Page 7 of 10 Pages

On December 19, 2006, the Trust transferred to the Partnership all 5,409,507 shares of Wilshire Bancorp Common Stock then owned by the Trust. The Kohs formed the Partnership under the laws of the State of Nevada on June 3, 2005. The Partnership, which is authorized to engage in any business activity which may lawfully be conducted by a Nevada limited partnership, is governed by a Limited Partnership Agreement, dated January 5, 2006, and as amended (the “Partnership Agreement”). The Kohs are the sole general partners and the sole limited partners of the Partnership. Mr. and Mrs. Koh each own a 0.5% percentage interest, as general partners, and a 49.5% percentage interest, as limited partners, in the Partnership. The general partners of the Partnership have exclusive management and control of the business of the Partnership, and all decisions regarding the management and affairs of the Partnership are made by the general partners. Under the Partnership Agreement, transfers of interests in the Partnership are subject to the approval of a majority in interest of the general partners and a right of first refusal in the Partnership and the other partners, except that certain permitted transfers, including, without limitation, to lineal descendents of the partners, are not subject to such restrictions.

The Kohs established the Charitable Foundation as a not-for-profit corporation under the laws of the State of Delaware on June 21, 2004. The Charitable Foundation is a 501(c)(3) tax exempt organization. The business and affairs of the Charitable Foundation are managed and all corporate powers are exercised by or under the direction of the Charitable Foundation’s board of directors. The Board of Directors currently consists of Steven Koh, Jung O. Koh, Samuel Koh, Christine Koh, Agnes Park, Chris Park and Peter Koh. As “Founder Directors,” Steven Koh and Jung O. Koh are entitled to serve as directors for their lifetimes, or until they become incapacitated. The officers of the Charitable Foundation are Steven Koh (Chairman), Samuel Koh (President), Peter Koh (Vice-President and Secretary), and Agnes Park (Secretary). The primary mission of the Charitable Foundation, as set forth in its bylaws, is to engage in charitable activities. The secondary purpose of the Charitable Foundation is to encourage the philanthropy and community service of the family members of Steven Koh and Jung O. Koh. As of the date of this filing, the Charitable Foundation holds 225,900 shares of Wilshire Bancorp Common Stock, all of which were transferred to the Charitable Foundation by the Trust.

The 5,635,407 shares (collectively, the “Shares”) of Wilshire Bancorp Common Stock reported as beneficially owned by Mr. and Mrs. Koh include (i) the 5,409,507 shares held by the Partnership and (ii) 225,900 shares held by the Charitable Foundation. Mr. and Mrs. Koh disclaim beneficial ownership of the shares of Wilshire Bancorp Common Stock held by the Charitable Foundation, except to the extent of their pecuniary interest therein.

None of the Reporting Persons has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been 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 of finding any violation with respect to such laws.

Information with respect to each Reporting Person is given solely by such Reporting Person, and no Reporting Person assumes responsibility for the accuracy or completeness of the information furnished by another Reporting Person. The Reporting Persons expressly disclaim that they have agreed to act as a group other than as described in this Amendment.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

Mr. Koh originally acquired the Shares in private transactions, on the open market and through the exercise of stock options granted to him for his service as Chairman of the Issuer's board of directors during the period between 1986 and 2004. The Shares were registered in the name of Mr. Koh, but the Shares were generally considered to be the community property of Mr. and Mrs. Koh. On June 4, 2004, the Kohs transferred to the Trust all of their rights and interest in and to all of the shares of Bank Common Stock (now Wilshire Bancorp Common Stock) then beneficially owned by them, to be held, administered and distributed according to the terms of the Trust Agreement. On December 27, 2004, Mr. Koh contributed 260,000 shares of Wilshire Bancorp Common Stock held by the Trust to the Charitable Foundation. An additional 23,000 shares were transferred from the Trust to the Charitable Foundation on February 10, 2006. The Charitable Foundation gifted 54,100 shares of Wilshire Bancorp Common Stock to an unaffiliated third party on April 20, 2006. On August 30, 2006, the Trust sold 5,773 shares of Wilshire Bancorp Common Stock on the open market. On December 19, 2006, all 5,409,507 shares of Wilshire Bancorp Common Stock then held by the Trust were transferred from the Trust to the Partnership. Item 5 summarizes all transactions in Wilshire Bancorp Common Stock engaged in by the Reporting Persons within the sixty days immediately preceding the filing of this Amendment.

Depending on various factors including, without limitation, the Issuer's business, financial position and prospects, the price levels of the shares of Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, (i) purchasing up to all of the outstanding Common Stock in the open market or otherwise, (ii) making an offer to purchase up all of the Issuer's outstanding shares of Common Stock, through a negotiated transaction or otherwise, (iii) causing the Common Stock to be deregistered through a squeeze out merger transaction or otherwise, or (iv) presenting proposals for consideration at annual or special meetings of the Issuer's stockholders.

The information set forth in Item 3 of this Amendment is hereby incorporated herein by reference.

(a) As of the date hereof, the Reporting Persons may be deemed to be the beneficial owners, within the meaning of Rule 13d-3 of the Exchange Act, of Wilshire Bancorp Common Stock in the following amounts and percentages, based on the number of shares of Common Stock outstanding as of October 31, 2006:

(i) Steven S. Koh: 5,635,407 shares, or 19.32% of the Common Stock outstanding

(b) The Kohs, as general partners, have the power to vote or direct the vote and to dispose or direct the disposition of the shares of Common Stock held in by the Partnership.

The business and affairs of the Charitable Foundation are managed and all corporate powers are exercised by or under the direction of the Charitable Foundation’s board of directors. The Kohs serves as “Founder Directors” of the Charitable Foundation and are entitled to serve as directors for their lifetimes. In addition, Steven Koh serves as Chairman of the Charitable Foundation. For this reason, each of the Reporting Persons may be deemed to have shared powers to vote or direct the vote and to dispose or direct the disposition of the Shares for the purposes of determining beneficial ownership under the Section 13d-3 of the Exchange Act.

(c) On December 19, 2006, all 5,409,507 shares of Wilshire Bancorp Common Stock then held by the Trust were transferred from the Trust to the Partnership.
