IV.        Information on the matters to be examined and discussed at the 66th Annual General Meeting

Below the Company’s Management presents some clarifications related to each item for resolution at the Annual General Meeting for the exercise of a conscious vote:

Clarifications

The Management accounts are presented through the Annual Management Report and the Financial Statements prepared by Copel’s Board of Executive Officers.

The Annual Management Report presents information on the macroeconomic scenario and the Company’s financial performance and operations, with comments on the main accounts of the statement of income for the year, in addition to information related to employees, social responsibility, the capital markets, corporate governance, etc.

On the other hand, the Financial Statements express the Company’s economic situation and equity changes in the fiscal year. By analyzing the Financial Statements, it is possible to assess the equity situation, liquidity indexes, profitability level and the degree of indebtedness of the Company.

It is worth mentioning that the Company’s financial statements have been prepared pursuant to the accounting practices adopted in Brazil which include those set forth by the Brazilian corporate laws, the pronouncements, guidance and interpretations issued by the Brazilian Accounting Practice Committee (CPC), approved by the Brazilian Securities Commission (CVM) and the Federal Accounting Council (CFC). Copel’s Financial Statements mainly consolidate electric power companies and, accordingly, are presented in compliance with the recommendations of the specific legislation applied to the electric power public utility concessionaires.

The Annual Report and the Financial Statements have been written by the Board of Executive Officers and approved by the Statutory Audit Committee and the Board of Directors. In addition, the Supervisory Committee issued an opinion on them, and they were deemed adequate for submission to the shareholders.

Furthermore, the Company’s Financial Statements were audited and received a favorable opinion by Deloitte Touche Tohmatsu Auditores Independentes, the Company’s independent auditors.

The analysis of the Statutory Audit Committee and the opinions of the Supervisory Committee and of the External Audit are attached to the Financial Statements.

Availability of Information

The Annual Report and the Financial Statements will be published in the Official Gazette of the State of Paraná, in the newspaper Folha de Londrina on April 22, 2021, pursuant to the applicable laws, being also available at the Company’s headquarters, at [B]³ Brasil, Bolsa, Balcão, and on Copel’s website (ir.copel.com).

Voting right

In this item of the agenda, only holders of common shares are entitled to vote.

Clarifications

The allocation of net income consists in determining the portions of net income to be appropriated to the legal and statutory revenue reserves, or to be distributed.

For the fiscal year 2020, the amount of said distribution is equivalent to 27.03% (gross percentage) and 25.00% (net percentage) of the adjusted net income, based on annual proposals from the Board of Executive Officers and the Board of Directors of the Company.

Allocation

Appropriation

From the net income for the fiscal year 2020, calculated in accordance with the Brazilian Corporation Law, in the amount of R$3,904,203,695.86 (three billion, nine hundred and four million, two hundred and three thousand, six hundred and ninety-five reais and eighty-six cents), the Board of Executive Officers proposes the following appropriations:

a) R$ 195,210,184.79 (one hundred and ninety-five million, two hundred and ten thousand, one hundred and eighty-four reais and seventy-nine cents), equivalent to 5% of the net income, to create the Legal Reserve, in accordance with article 193 of Law no. 6,404, of December 15, 1976, and with Article 87, paragraph 2, item II, of the Company’s Bylaws;

b) R$ 807,500,000.00 (eight hundred and seven million and five hundred thousando reais) to pay for interest on shareholders' equity, in partial replacement of compulsory minimum dividends, in compliance with article 202 of Law no. 6,404, of December 15, 1976 - the Brazilian Corporation Law; article 9, paragraph 7, of Law no. 9,249, of December 26, 1995, and article 88 and its paragraphs of the Company’s Bylaws;

c)  R$ 781,331.33 (seven hundred and eighty-one thousand, three hundred and thirty-one reais and thirty-three cents) to pay for complementary dividends to PNA stockholders, which were declared and paid, as resolved at the 260^th Ordinary Meeting of the Board of Directors, on September 16, 2020

d) R$ 210,275,576.76 (two hundred and ten million, two hundred and seventy-five thousand, five hundred and seventy-six reais and seventy-six cents) to pay for complementary dividends, in addition to the compulsory minimum, pursuant to article 202 of Law no. 6,404, of December 15, 1976; article 9, paragraph 7, of Law no. 9,249, of December 26, 1995; and article 88 of the Company’s Bylaws; and in compliance with CVM Resolution no. 683, of August 30, 2012, which approved the Technical Pronouncement CPC - ICPC no. 08 (R1), issued by the Brazilian Accounting Practice Committee (CPC), which governs accounting procedures for the proposal of dividends payment.

·  CVM Resolution 683, of 08.30.2012, approved and made mandatory for publicly-held companies the application of Technical Interpretation ICPC 08 (R1), issued by the Accounting Pronouncements Committee - CPC, whose content establishes the rules inherent to the accounting of the proposal for payment of dividends. According to the legal basis mentioned above, the interest on own capital proposed may only be imputed to the minimum mandatory dividends, net of withholding income tax, which is levied at the rate of 15% (fifteen percent) on this type of income. However, the portion of interest on own capital distributed to exempt and immune shareholders is not subject to such taxation. The amount of income tax withheld at source, on the income of the other shareholders, subject to taxation, was R$76,401,315.50 (seventy-six million, four hundred and one thousand, three hundred and fifteen reais and fifty cents), resulting in an effective rate of 9.46% (nine integers and forty-six hundredths percent) for the 2020 fiscal year. In this way, the proposal for the payment of interest on own capital, in the gross amount of R$807,500,000.00 (eight hundred and seven million, five hundred thousand reais), will provide the shareholders with a net remuneration in the amount of R$731,098,684.50 (seven hundred and thirty-one million, ninety-eight thousand, six hundred and eighty-four reais and fifty cents), which, added to the R$781,331.33 (seven hundred and eighty-one thousand, three hundred and thirty-one reais and thirty-three cents), proposed as complementary dividends, declared and paid to the holders of PNA shares, and to the R$210,275,576.76 (two hundred and ten million, two hundred and seventy-five thousand, five hundred and seventy-six Brazilian reais and seventy-six cents), proposed as complementary dividends to the minimum mandatory dividends, make up a total remuneration, net of income tax, in the amount of R$942,155,592.59 (nine hundred and forty-two million, one hundred and fifty-five thousand, five hundred and ninety-two Brazilian reais and fifty-nine cents), corresponding to the minimum statutory dividends.

e)   R$2,750,065,462.26 (two billion, seven hundred and fifty million, sixty-five thousand, four hundred and sixty-two reais and twenty-six cents), for the constitution of a retention of profits reserve, whose purpose is to ensure the Company's investment program, as established in article 196 of Law no. 6,404, of December 15, 1976, and in article 87, paragraph 2, item IV, of the Bylaws.

The profit retention reserve corresponds to the sum of the remaining balance of net income for the year, after the constitution of the legal reserve, with the realization of equity valuation adjustments, less interest on capital and dividends proposed to shareholders.

·        The Executive Board clarifies that the Company started the fiscal year 2020 with a balance of the profit retention reserve in the amount of R$4,846,238,690.10 (four billion, eight hundred and forty-six million, two hundred and thirty-eight thousand, six hundred and ninety reais and ten cents). As a result of the proposed allocations of net income for 2020, the balance of this reserve would be R$7,596,304,152.36 (seven billion, five hundred and ninety-six million, three hundred and four thousand, one hundred and fifty-two Brazilian reais and thirty-six cents). However, the Board of Directors, in accordance with the provisions of paragraph 2 of article 204 of Law no. 6,404, of December 15, 1976, and in accordance with the Dividend Policy approved on January 20, 2021, decided at its 212^th Ordinary Meeting, held on March 17, 2021, to approve a specific proposal for the payment of interim dividends from the retained earnings reserve of previous years in the amount of R$1,507,448,948.14 (one billion, five hundred and fifty million dollars). Thus, the balance, the balance of the retention of profits reserve on 12.31.2020 became R$6,088,855,204.22 (six billion, eighty-eight million, eight hundred fifty-five thousand, two hundred four reais and twenty-two cents).

The following is a statement of the changes that occurred in the "retained earnings" account, including the proposed destinations:

Asset changes: FY 2020 net income: R$3,904,203,695.86; ( - ) Legal reserve (5% of net income for the year): R$195,210,184.79 = Adjusted net income: R$3,708,993,511.07; ( + ) Realization of equity valuation adjustments - net of taxes: R$59,628,859.28 = Calculation basis for mandatory minimum dividends: R$3,768,622,370.35; ( - ) Interest on Equity - gross: R$807,500,000.00; (-) Complementary Dividends (PNA shares): R$781,331.33; (-) Complementary dividends to the mandatory minimums: R$210,275,576.76; (-) Profit retention reserve: R$2,750,065,462.26.

The financial statements for 2020 reflect the effects of the accounting records of the destinations previously specified, based on the assumption of their approval by the 66^th Annual General Meeting, as established in paragraph 3 of article 176 of Law no. 6,404, of December 15, 1976.

Payment of profit sharing and productivity incentives:

Federal Law no. 10,101, of December 19, 2000, as well as State Law no. 16,560, of August 9, 2010, and State Decree no. 1978, of December 20, 2007, regulate the participation of employees in the Company's profits, as an instrument of integration between capital and labor and as an incentive to productivity, pursuant to Article 7, item XI of the Constitution of the Republic. In compliance with this legislation, the Executive Board proposes the distribution, as profit sharing, of R$ 420,004,161.37 (four hundred and twenty million, four thousand, one hundred and sixty-one reais and thirty-seven cents) to be paid to employees of the Parent Company and its wholly-owned subsidiaries. Such participation is provisioned for in the financial statements for 2020, specifically under "personnel expenses", in accordance with item 26.2 of the CVM/SNC/SEP Circular Letter no. 1, of February 14, 2007.

Following the same procedures used in previous years, the policy takes into consideration the compensation of the previous fiscal year, without any increase.

The goal of this policy is to reward the Company's Chief Officers for results obtained in the fiscal year and for the achievement of goals set forth in the Company's strategic plan.

The compensation paid to the Company’s Chief Officers and members of the Board of Directors and of the Supervisory Board is the sole responsibility of Copel’s wholly-owned subsidiaries, controlled companies or direct and indirect controlled companies. There is no remuneration or benefit linked to the occurrence of any corporate even such as the sale of the shareholding control of the Company.

In 2021, so as to fully comply with item 1 of Article 12 of CVM’s Rule no. 481/2009, the Company’s majority shareholder has proposed the annual compensation limit, including charges, of up to R$13,002,528.27, as follows:

a) the compensation paid to the Company’s Chief Officers shall be the same one paid in the previous fiscal year;

b) for each member of the Board of Directors, the compensation paid shall be of fifteen percent (15%) of the monthly compensation that, on average, is assigned to the Chief Executive Officer, including the extra 13th salary paid annually and calculated proportionally over the previous 12 months. The chairman of the Board of Directors shall be granted a monthly bonus equivalent to 50% of the monthly compensation paid to the members of the Statutory Audit Committee;

c) for each member of the Supervisory Board the monthly compensation paid shall be of fifteen percent (15%) of the monthly compensation that, on average, is assigned to the Chief Executive Officer, including the extra 13th salary paid annually and calculated proportionally over the previous 12 months;

d) for each member of the Statutory Audit Committee the monthly compensation paid shall be equivalent to the monthly compensation paid to the members of the Supervisory Board. A bonus of R$5,000.00 is also paid;

e) for each member of the Nomination and Evaluation Committee the monthly compensation paid shall be equivalent to 8.5% (eight point five per cent) of the monthly compensation paid to the Company's Chief Executive Officer;

f) for each of the members of the Investment and Innovation Committee and the Sustainable Development Committee the monthly compensation paid shall be equivalent to 6.5% of the compensation of the Company's Chief Executive Officer.

Thus, from the annual compensation limit as stated above, up to R$9,876,902.86 (inclusive of social charges from the National Social Security Institute - INSS, the Indemnity Fund for Employees - FGTS, the Company’s own pension plan and health care assistance) shall be proposed as global annual compensation for the Executive Officers; up to R$748,179.94  (inclusive of social charges from the INSS) as global annual compensation for the Board of Directors; up to R$805,146.96 (inclusive of social charges from the INSS) as global annual compensation for the Supervisory Board; up to R$1,016,765.83 (inclusive of social charges from the INSS) as global annual compensation for the members of the Statutory Audit Committee; up to R$281,211.53 (inclusive of social charges from the INSS), as global annual compensation for the members of the Nomination and Evaluation Committee; up to R$137,160.58, (inclusive of social charges from the INSS), as global annual compensation for the members of the Investment and Innovation Committee; up to R$137,160.58 (inclusive of social charges from the INSS), as global annual compensation for the members of the Sustainable Development Committee; and for the Minority Shareholders Committee, considering its way of acting, no remuneration values will be proposed.
