GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (1) The condensed consolidated financial statements included herein have been prepared by the Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Registrant believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Registrant's 2002 annual report on Form 10-K. (2) In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments, consisting of only a normal and recurring nature, necessary to present fairly the financial position of the Registrant as of March 31, 2003, and December 31, 2002, and the results of operations and cash flows for the interim periods presented. (3) Inventories consisted of the following at the respective balance sheet dates: March 31, 2003 December 31, 2002 -------------- ----------------- Raw materials $10,217,227 $ 9,911,022 Work-in-process 1,667,424 1,744,372 Finished goods 5,803,849 6,086,615 ----------- ----------- $17,688,500 $17,742,009 =========== =========== (4) The following table reconciles the numerators and denominators used in the calculation of basic and diluted earnings per share (EPS): Quarter Ended March 31, ----------------------- 2003 2002 ---- ---- Numerators: Numerator for both basic and diluted EPS, net income $25,908,538 $18,953,226 Denominators: Denominator for basic EPS, weighted-average shares outstanding 75,944,285 75,313,856 Potentially dilutive shares resulting from stock plans 884,742 1,033,965 ----------- ----------- Denominator for diluted EPS 76,829,027 76,347,821 =========== =========== Shares related to stock plans not included in diluted average common shares outstanding because their effect would be antidilutive 1,371,099 508,724 (5) At March 31, 2003, the Company has two stock option plans and an employee stock purchase plan. The Company accounts for these plans under the recognition and measurement principles of APB Opinion No. 25 (Accounting for Stock Issued to Employees) and related interpretations. No stock-based employee compensation cost is reflected in net income, as all options granted under these plans have an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of FASB Statement No. 123 (Accounting for Stock-Based Compensation) to stock-based employee compensation. - 5 -

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONT.) (9) New Accounting Pronouncements -- FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others," changes current practice in accounting for, and disclosure of, guarantees. Interpretation No. 45 will require certain guarantees to be recorded as liabilities at fair value on the Company's balance sheet. Current practice requires that liabilities related to guarantees to be recorded only when a loss is probable and reasonably estimable, as those terms are defined in FASB Statement No. 5, "Accounting for Contingencies." Interpretation No. 45 also requires a guarantor to make significant new disclosures, even when the likelihood of making any payments under the guarantee is remote, which is another change from current practice. The disclosure requirements of Interpretation No. 45 are effective immediately; however the Company currently does not have significant third party guarantees or warranty liabilities that would require disclosure under the interpretation. The initial recognition and measurement provisions are applicable on a prospective basis to guarantees issued or modified after December 31, 2002. The recognition and measurement provisions were adopted, prospectively, as of January 1, 2003, and did not have an effect on the Company's consolidated financial position or results of operations. In December 2002, the FASB issued SFAS 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure -- an amendment of FASB Statement No. 123." SFAS 148 amends SFAS 123, "Accounting for Stock-Based Compensation," to provide alternative methods of transition for a voluntary change to the fair-value based method of accounting for stock-based employee compensation. In addition, SFAS 148 amends the disclosure requirements of Statement No. 123 to require disclosure in interim financial statements regarding the method used on reported results. The Company does not intend to adopt a fair-value based method of accounting for stock-based employee compensation until a final standard is issued by the FASB that requires this accounting. Proforma disclosures of quarterly earnings are included in Note 5 of this quarterly statement. In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities." This standard clarifies the application of Accounting Research Bulletin No. 51, "Consolidated Financial Statement," and addresses consolidation by business enterprises of variable interest entities (more commonly known as Special Purpose Entities or SPE's). Interpretation No. 46 requires existing unconsolidated variable interest entities to be consolidated by their primary beneficiaries if the entities do not effectively disperse risk among the parties involved. Interpretation No. 46 also enhances the disclosure requirements related to variable interest entities. This statement is effective for variable interest entities created or in which an enterprise obtains an interest after January 31, 2003. Interpretation No. 46 will be effective for the Company beginning January 1, 2004, for all interest in variable interest entities acquired before February 1, 2003. The adoption of Interpretation No. 46 is not expected to have an effect on the Company's consolidated financial statements. - 7 -

GENTEX CORPORATION AND SUBSIDIARIES ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION RESULTS OF OPERATIONS: FIRST QUARTER 2003 VERSUS FIRST QUARTER 2002 Net Sales. Net sales for the first quarter of 2003 increased by approximately $26,260,000, or 29%, when compared with the first quarter last year. Net sales of the Company's automotive mirrors increased by $26,283,000, or 31%, as electrochromic mirror unit shipments increased by 23% from approximately 2,056,000 in the first quarter of 2002 to 2,535,000 in the current quarter. This increase reflected the increased penetration of interior and exterior electrochromic Night Vision Safety(TM) (NVS(R)) Mirrors on 2003 model year vehicles plus additional content. Unit shipments to customers in North America increased by 14%, primarily due to increased penetration, despite flat automotive production levels. Mirror unit shipments to automotive customers outside North America increased by 36% compared with the first quarter in 2002, primarily due to increased interior and exterior mirror sub-assembly shipments to European and Asian-Pacific automakers. Net sales of the Company's fire protection products decreased less than 1%, primarily due to lower sales of certain of the Company's smoke detectors. Cost of Goods Sold. As a percentage of net sales, cost of goods sold decreased from 60% in the first quarter of 2002 to 58% in the first quarter of 2003. This decreased percentage primarily reflected the higher sales level leveraged over the fixed overhead costs and product mix, partially offset by annual customer price reductions. Operating Expenses. Research and development expenses increased approximately $622,000, but decreased from 6% to 5% of net sales, when compared with the same quarter last year, primarily reflecting additional staffing, engineering and testing for new product development, including mirrors with additional electronic features. Selling, general and administrative expenses increased approximately $486,000, but decreased from 6% to 5% of net sales, when compared with the first quarter of 2002. This increased expense primarily reflected the continued expansion of the Company's overseas sales and engineering offices. Other Income - Net. Other income decreased by approximately $1,514,000 when compared with the first quarter of 2002, primarily due to realized losses on the sale of equity investments. FINANCIAL CONDITION: Cash flow from operating activities for the three months ended March 31, 2003, increased $4,522,000 to $40,877,000, compared to $36,355,000 for the same period last year, primarily due to increased net income. Capital expenditures for the three months ended March 31, 2003, were $6,630,000, compared to $15,254,000 for the same period last year, primarily due to the purchase of a company airplane in 2002. Management considers the Company's working capital and long-term investments totaling approximately $466,871,000 at March 31, 2003, together with internally generated cash flow and an unsecured $5,000,000 line of credit from a bank, to be sufficient to cover anticipated cash needs for the next year and for the foreseeable future. On October 8, 2002, the Company announced a share repurchase plan, under which the Company may purchase up to 4,000,000 shares based on a number of factors, including market conditions, the market price of the Company's common stock, anti-dilutive effect on earnings, available cash and other factors as the Company deems appropriate. During the quarter ended March 31, 2003, the Company repurchased 415,000 shares at a cost of approximately $10,247,000. TRENDS AND DEVELOPMENTS: The Company is subject to market risk exposures of varying correlations and volatilities, including foreign exchange rate risk, interest rate risk and equity price risk. There were no significant changes in the market risks reported in the Company's 2002 Form 10-K report during the quarter ended March 31, 2003. - 8 -

TRENDS AND DEVELOPMENTS (CONT.): The Company has some assets, liabilities and operations outside the United States, which currently are not significant. Because the Company sells its automotive mirrors throughout the world, it could be significantly affected by weak economic conditions in worldwide markets that could reduce demand for its products. The Company utilizes the forecasting services of J.D. Power and Associates, and its current forecasts for light vehicle production are approximately 16.0 million in North America, 15.7 million in Western Europe and 20.3 million in the Asia-Pacific region for calendar 2003. In addition to price reductions over the life of its long-term agreements, the Company continues to experience pricing pressures from its automotive customers, which have affected, and which will continue to affect, its margins to the extent that the Company is unable to offset the price reductions with productivity improvements, engineering and purchasing cost reductions, and increases in unit sales volume. In addition, profit pressures at certain automakers are resulting in increased cost reduction efforts by them, including requests for additional price reductions, decontenting certain features from vehicles, and warranty cost-sharing programs, which could adversely impact the Company's sales growth and margins. The Company also continues to experience from time to time some pressure for select raw material cost increases. The Company generally supplies NVS(R) Mirrors to its customers worldwide under annual blanket purchase orders. The Company currently supplies NVS(R) Mirrors to DaimlerChrysler AG and General Motors Corporation under long-term agreements. The long-term supply agreement with DaimlerChrysler AG runs through the 2003 Model Year, while the GM contract is through the 2004 Model Year for inside mirrors. Automakers have been experiencing increased volatility and uncertainty in executing planned new programs which have, in some cases, resulted in cancellations or delays of new vehicle platforms, package reconfigurations and inaccurate volume forecasts. In addition, there remains uncertainty associated with automotive light vehicle production schedules for the balance of the year due to weaker automotive sales, the economy and the war in Iraq. This increased volatility and uncertainty has made it more difficult for the Company to forecast future sales and effectively utilize capital, engineering, research and development, and human resource investments. The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its consolidated financial statements. On October 1, 2002, Magna International acquired Donnelly Corporation. Magna Donnelly is the Company's major competitor for sales of automatic-dimming rearview mirrors to domestic and foreign vehicle manufacturers and their mirror suppliers. The Company also sells certain automatic-dimming rearview mirror sub-assemblies to Magna Donnelly. At this time, it is too early to determine the impact, if any, of Magna's acquisition of Donnelly upon the Company. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The information called for by this item is provided under the caption "Trends and Developments" under Item 2 -- Management's Discussion and Analysis of Results of Operations and Financial Condition. - 9 -

ITEM 4. CONTROLS AND PROCEDURES As of March 31, 2003, an evaluation was performed under the supervision and with the participation of the Company's management, including the CEO and CFO, of the effectiveness of the design and operation of the Company's disclosure controls and procedures [(as defined in Exchange Act Rules 13a -- 14(c) and 15d -- 14(c)]. Based on that evaluation, the Company's management, including the CEO and CFO, concluded that the Company's disclosure controls and procedures were effective as of March 31, 2003, to ensure that material information relating to the Company would be made known to them by others within the Company, particularly during the period in which this Form 10-Q was being prepared. There have been no significant changes in the Company's internal controls or in other factors that could significantly affect internal controls subsequent to March 31, 2003, nor any significant deficiencies or material weaknesses in such controls requiring corrective actions. As a result, no corrective actions were required or taken. Statements in this Quarterly Report on Form 10-Q which express "belief", "anticipation" or "expectation" as well as other statements which are not historical fact, are forward-looking statements and involve risks and uncertainties described under the headings "Management's Discussion and Analysis of Results of Operations and Financial Condition" and "Trends and Developments" that could cause actual results to differ materially from those projected. All forward-looking statements in this Report are based on information available to the Company on the date hereof, and the Company assumes no obligation to update any such forward-looking statements.

The registered office of the Corporation shall be as specified in the Articles of Incorporation or such other place as determined by the Board of Directors if notice thereof is filed with the state of Michigan. The Corporation shall keep records containing the names and addresses of all shareholders, the number, class and series of shares held by each, and the dates when they respectively became holders of record thereof, at its registered office or at the office of its transfer agent. SECTION 2. OTHER OFFICES. The business of the Corporation may be transacted in such locations other than the registered office, within or outside the state of Michigan, as the Board of Directors may from time to time determine. ARTICLE II. CAPITAL STOCK SECTION 1. STOCK CERTIFICATES. Certificates representing shares of the capital stock of the Corporation shall be in such form as is approved by the Board of Directors. Certificates shall be signed by the Chairman of the Board of Directors, Vice Chairman of the Board of Directors, President or a Vice President, and may also be signed by another officer designated by the Board of Directors, and shall be sealed with the seal of the Corporation, or a facsimile thereof, if one be adopted. The signatures of the officers may be facsimiles. In the event an officer who has signed, or whose facsimile signature has been placed upon, a certificate ceases to be such officer before the certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer at the date of issue. SECTION 2. REPLACEMENT OF LOST OR DESTROYED CERTIFICATES. In the event of the loss or destruction of a stock certificate, no new certificate shall be issued in place thereof until the Corporation has received from the registered holder such assurances, representations, warranties and/or guarantees as the Board of Directors, in its sole discretion, shall deem advisable, and until the Corporation receives such indemnification protecting it against any claim that may be made on account of such lost or destroyed certificate, or the issuance of any new certificate in place thereof, including an indemnity bond in such amount and with sureties, if any, as the Board of Directors, in its sole discretion, deems advisable. SECTION 3. TRANSFER OF SHARES. Shares of stock of the Corporation shall be transferable only upon the books of the Corporation. The old certificates shall be surrendered to the Corporation by delivery thereof to the person in charge of the stock transfer books of the Corporation, or to such other person as the Board of Directors may designate, properly endorsed for transfer, and such certificates shall be canceled before a new certificate is issued. The Corporation shall be entitled to treat the person in whose name any share, right or option is registered as the owner thereof for all purposes, and shall not be bound to recognize any equitable or other claim with respect thereto, regardless of any notice thereof, except as may be specifically required by the laws of the state of Michigan. SECTION 4. RULES GOVERNING STOCK CERTIFICATES. The Board of Directors shall have the power and authority to make all such rules and regulations as they may deem expedient concerning the issue, transfer and registration of certificates - 16 -

of stock, and may appoint a transfer agent and a registrar of transfer, and may require all such certificates to bear the signature of such transfer agent and of such registrar of transfers. SECTION 5. RECORD DATE FOR STOCK RIGHTS. The Board of Directors may fix a date not exceeding sixty (60) days preceding the date of payment of any dividend, or the date for the allotment of rights, or the date when any change or conversion or exchange of capital stock shall go into effect, as a record date for the determination of the shareholders entitled to receive payment of any such dividends, or any such allotment of rights, or to exercise the rights with respect to any such change, conversion, or exchange of capital stock; provided, however, that such date shall not precede the date on which the Board takes action to establish the record date. Only shareholders of record on the date so fixed shall be entitled to receive payment of such dividends, or allotment of rights, or exercise such rights, as the case may be, notwithstanding any transfer of any stock on the books of the Corporation after any such record date is fixed. In the event the Board of Directors shall fail to fix a record date as provided in this section of these Bylaws, the record date for the purposes specified herein shall be the close of business on the date on which the resolution of the Board of Directors relating thereto is adopted. SECTION 6. DIVIDENDS. The Board of Directors, in its discretion, may from time to time declare and make a distribution to shareholders in respect of the Corporation's outstanding shares, payable in cash, the Corporation's indebtedness (but not the Corporation's shares) or the Corporation's other property, including the shares or indebtedness of other corporations; provided, however, no such distribution shall be made if, after giving effect to the distribution, the Corporation would not be able to pay its debts as they become due in the usual course of business, or the Corporation's total assets would be less than its total liabilities plus the amount that would be needed if the Corporation were to be dissolved at the time of the distribution to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution. In addition, the Board of Directors, in its discretion, from time to time may declare and direct the payment of a share dividend of the Corporation's shares, issued pro rata and without consideration, to the Corporation's shareholders or to the shareholders of one or more classes or series; provided, however, shares of one class or series may not be issued as a share dividend in respect of shares of another class or series unless the Articles of Incorporation so authorize, a majority of the votes entitled to be cast by the class or series to be issued approve the issue, or there are no outstanding shares of the class or series to be issued. SECTION 7. TREASURY SHARES. Shares that have been issued and reacquired by the Corporation shall constitute authorized but unissued shares. SECTION 8. REDEMPTION OF CONTROL SHARES. Control shares acquired in a control share acquisition, with respect to which no acquiring person statement has been filed with the Corporation, shall, at any time during the period ending sixty (60) days after the last acquisition of control shares or the power to direct the exercise of voting power of control shares by the acquiring person, be subject to redemption by the Corporation. After an acquiring person statement has been filed with the Corporation and after the meeting at which the voting rights of the control shares acquired in a control share acquisition are submitted to the shareholders, the shares shall be subject to redemption by the Corporation unless the shares are accorded full voting rights by the shareholders as provided in Section 798 of the Michigan Business Corporation Act. Redemptions of shares pursuant to this bylaw shall be at the fair value of the shares pursuant to procedures adopted by the Board of Directors of the Corporation. The terms "control shares," "control share acquisition," "acquiring person statement," "acquiring person," and "fair value" as used in this bylaw, shall have the meanings ascribed to them in Chapter 7B of the Michigan Business Corporation Act. ARTICLE III. SHAREHOLDERS SECTION 1. PLACE OF MEETINGS. Meetings of shareholders shall be held at such place, within or outside the state of Michigan, as may be determined from time to time by the Board of Directors. - 17 -

SECTION 2. ANNUAL MEETING. Annual meetings of shareholders for election of directors and for such other business as may come before the meeting shall be held on such date prior to the first day of June of each year as the Board of Directors may determine from time to time. SECTION 3. SPECIAL MEETINGS. Special meetings of shareholders shall be called at the direction of the Board of Directors by the Chairman or the Secretary, or upon receipt by either of them of a request in writing, stating the purpose or purposes thereof, and signed by shareholders of record owning more than fifty percent (50%) of the voting shares of the Corporation issued and outstanding, or by a majority of the directors then in office. SECTION 4. RECORD DATE FOR NOTICE AND VOTE. The Board of Directors may fix a date not more than sixty (60) nor less than ten (10) days before the date of a shareholders' meeting as the record date for the purpose of determining shareholders entitled to notice of and to vote at the meeting or adjournments thereof; provided, however, that such date shall not precede the date on which the Board takes action to establish the record date. In the event the Board of Directors fails to fix such a record date, the record date for determination of shareholders shall be the close of business on the day next preceding the day on which notice is given. SECTION 5. NOTICE OF SHAREHOLDER MEETINGS. Written notice of the time, place, and purposes of any meeting of shareholders shall be given to shareholders entitled to vote thereat, not less than ten (10) nor more than sixty (60) days before the date of the meeting, which notice may be given either by delivery in person to such shareholders or by mailing such notice to shareholders at their addresses as the same appear on the stock books of the Corporation. A shareholder's attendance at a meeting will result in a waiver of objection to lack of notice or defective notice unless the shareholder, at the beginning of the meeting, objects to the holding of the meeting or the transaction of business at the meeting, and a waiver of objection to consideration of a particular matter at the meeting as not being within the purpose or purposes described in the meeting notice unless the shareholder objects to considering the matter when it is presented. SECTION 6. VOTING LISTS. The Corporation's officer or agent having charge of its stock transfer books shall prepare and certify a complete list of the shareholders entitled to vote at a shareholders' meeting or any adjournment thereof, which list shall be arranged alphabetically within each class and series, and shall show the address of and number of shares held by each shareholder. The list shall be produced at the time and place of the meeting of shareholders and be subject to inspection by any shareholder at any time during the meeting. If for any reason these requirements with respect to this shareholder list have not been complied with, any shareholder, either in person or by proxy, who in good faith challenges the existence of sufficient votes to carry any action at the meeting, may demand that the meeting be adjourned and the same shall be adjourned until the requirements are complied with; provided, however, that failure to comply with such requirements does not affect the validity of any action taken at the meeting before such demand is made. SECTION 7. VOTING. Except as provided in the Articles of Incorporation or Bylaws of the Corporation, each shareholder entitled to vote at a meeting of shareholders or to express consent or dissent without a meeting, shall be entitled to one (1) vote, in person or by proxy, for each share entitled to vote that is held by such shareholder; provided, however, no proxy shall be voted after three years from its date unless such proxy expressly provides for a longer period. For purposes of this section, without limiting the manner in which a shareholder may authorize another person or persons to act as proxy, a proxy granted by execution of a writing, facsimile, or other means of electronic or digital transmission to the person or persons who will hold the proxy or to a proxy solicitation firm, proxy support service organization, or similar agent fully authorized by the person who will hold the proxy to receive that transmission, shall constitute valid means of granting proxy authority. A vote may be cast either orally or in writing as announced or directed by the person presiding at the meeting prior to the taking of the vote. When an action other than the election of directors is to be taken by vote of the shareholders, it shall be authorized by a majority of the votes cast by the holders of shares entitled to vote on the action, unless a greater vote is required by the Michigan Business Corporation Act or of the Articles of Incorporation, in which case such express provision shall govern or control the decision of such question. Except as otherwise expressly required by the Articles of Incorporation, directors shall be elected by a plurality of the votes cast at an election. SECTION 8. QUORUM. Shares equaling a majority of all of the voting shares of the capital stock of the Corporation issued and outstanding, represented in person or by proxy, shall constitute a quorum at meetings of shareholders. Meetings at which less than a quorum is represented may be adjourned by a vote of a majority of the shares present to a further date without further notice other than the announcement at such meeting, and when the quorum shall be present upon such adjourned date, any business may be transacted which might have been transacted at the meeting as originally called. - 18 -

Shareholders present in person or by proxy at any meeting of shareholders may continue to do business until adjournment, notwithstanding the withdrawal of shareholders to leave less than a quorum. SECTION 9. CONDUCT OF MEETINGS. The officer who is to preside at meetings of shareholders pursuant to Article V of these Bylaws, or his or her designee, shall determine the agenda, the order in which business shall be conducted and rules for the conduct of the meeting (which shall be fair to shareholders), unless the agenda, the order of business and/or such rules have been fixed by the Board of Directors. Such officer or designee shall call meetings of shareholders to order and shall preside, shall appoint a person to act as secretary of the meeting, and may appoint a parliamentarian, who may be the same person as the secretary. SECTION 10. INSPECTORS OF ELECTIONS. The Board of Directors may, in advance of a meeting of shareholders, appoint one or more inspectors to act at the meeting or any adjournment thereof. In the event inspectors are not so appointed, or an appointed inspector fails to appear or act, the person presiding at the meeting of shareholders may appoint one or more persons to fill such vacancy or vacancies, or to act as inspector. The inspector(s) shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots, or consents, hear and determine challenges and questions arising in connection with the right to vote, count and tabulate votes, ballots or consents, determine the results, and do such acts as are proper to conduct the election or vote with fairness to all shareholders. SECTION 11. NOTICE OF SHAREHOLDER PROPOSALS. (a) Except for the election of directors, which is governed by Article VI of the Corporation's Articles of Incorporation, only such business shall be conducted at any meeting of shareholders, and only such proposals shall be acted upon at such meetings, as shall have been brought before the meeting: (i) by, or at the direction of the Board of Directors; or (ii) by any shareholder of the Corporation who complies with the notice procedures set forth in this Section of these Bylaws.

A shareholder's notice to the Secretary shall set forth, as to each matter the shareholder proposes to bring before the meeting: (i) a brief description of a proposal desired to be brought before the meeting and the reasons for conducting such business at the meeting; (ii) the name and address, as they appear on the Corporation's stock record, of the shareholder proposing such business and any other shareholders known by such shareholder to be supporting such proposal; (iii) the class and number of shares of the Corporation's stock which are beneficially owned by the shareholder on the date of such shareholder notice and by any other shareholders known by such shareholder to be supporting such proposal on the date of such shareholder notice; and (iv) any financial interest of the shareholder in such proposal. (b) If the presiding officer at the meeting of shareholders determines that a shareholder proposal was not made in accordance with the terms of this Section, the presiding officer shall declare the matter to be out of order and the matter shall not be acted upon at the meeting. (c) Nothing contained in this Section shall prevent the consideration and approval or disapproval at any meeting of shareholders of reports of officers, directors, and committees of the Board of Directors, but, in connection with such reports, no business shall be acted upon at such meeting unless stated, filed, and received as provided herein.
