REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Administrator

American Savings Bank 401(k) Plan and

Audit Committee and Pension Investment Committee of

Hawaiian Electric Industries, Inc.

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the American Savings Bank 401(k) Plan (the Plan) as of December 31, 2019 and 2018, and the related statement of changes in net assets available for benefits for the year ended December 31, 2019, and the related notes and schedule (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2019 and 2018, and the changes in net assets available for benefits for the year ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 2 to the financial statements, the Plan changed the presentation and disclosure of its investment in a master trust in 2019 and 2018 due to the adoption of Accounting Standards Update No. 2017-06, Employee Benefit Plan Master Trust Reporting.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information contained in the Schedule of Assets (Held at End of Year) has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion,

401(k) Plan

Notes to Financial Statements

December 31, 2019 and 2018

1. Plan Description

The American Savings Bank 401(k) Plan (the “Plan” or “ASB 401(k) Plan”) was established by American Savings Bank, F.S.B. (“ASB” or the “Bank”) effective January 1, 2008. The Plan is a defined contribution 401(k) plan that provides certain tax-qualified retirement benefits to eligible employees. ASB is the only participating employer in the Plan at this time.

The following description of the Plan provides only general information. Participants should refer to the Plan document for its detailed provisions, which are also summarized in the most recent prospectus for the Plan and in the summary plan description:

a. Plan Administration

ASB is the Administrator of the Plan. The board of directors of Hawaiian Electric Industries, Inc. (“HEI”), which is the parent corporation of the controlled group of which ASB is a part, has established the Hawaiian Electric Industries, Inc. Pension Investment Committee (the “PIC”) to oversee the administration of the Plan and the investment options offered under the Plan. The PIC has appointed an Administrative Committee to oversee the day-to-day administration of the Plan, which includes the discretionary authority to interpret the Plan’s provisions. The PIC has also appointed an Investment Committee to oversee the day-to-day financial affairs of the Plan. The members of the Administrative and Investment Committees are employees of HEI and its subsidiaries, and the Administrative and Investment Committees are chaired by a member of the PIC.

ASB and the Plan pay the Plan’s administrative fees. The Plan’s trustee and certain of the mutual funds offered under the Plan provide revenue credits to the Plan, which are used to help pay for Plan administration, including recordkeeping. Participants are currently charged fees to initiate and maintain Plan loans and for certain distributions. Participants may also be charged fees for other activities that they or their spouses or other beneficiaries initiate, such as determinations with respect to domestic relations orders and the administration of qualified domestic relations orders.

b. Eligibility

For purposes of salary reduction (“401(k)”) contributions, all common law employees of ASB (other than leased employees) are eligible to participate in the Plan upon one hour of service. Participation in the 401(k) portion of the Plan is voluntary for eligible employees.

c. 401(k) Contributions

Employees may make 401(k) contributions of up to 100% of available eligible compensation (i.e., compensation that is available after payroll taxes and other applicable withholdings) subject to a federal tax limit of $19,000 in 2019.

Participants who are age 50 or older, or who attain age 50 during the year, may elect to make catch-up 401(k) contributions, subject to a federal tax limit of $6,000 in 2019.

For purposes of calculating contributions to the Plan, compensation is defined as Box 1, W-2 earnings, modified to (a) exclude fringe benefits, employer nonelective contributions to a cafeteria plan, reimbursements, moving and other expense allowances, special executive compensation, signing bonuses, retention bonuses, service awards, and similar nonperformance based awards, and (b) include pre-tax elective contributions made by ASB to the Plan, a cafeteria plan or a transportation spending plan. Special executive compensation

American Savings Bank

401(k) Plan

Notes to Financial Statements

December 31, 2019 and 2018

is noncash compensation and/or nonqualified deferred compensation, available only to a select group of management employees.

Federal tax law limits the amount of annual compensation that may be taken into account in determining contributions to the Plan. The maximum limit was $280,000 in 2019.

A participant may designate all or a portion of the participant’s 401(k) contributions as Roth after-tax contributions. To the extent a participant does not affirmatively designate a contribution as a Roth contribution, such contribution will constitute a pre-tax contribution.

d. Rollover Contributions

A participant or an eligible employee (whether or not a participant) may make a direct rollover to the Plan of an eligible rollover distribution from another qualified defined benefit or defined contribution plan. The Plan may accept direct rollovers of after-tax amounts from qualified retirement plans. The Administrative Committee may consider traditional rollovers by eligible employees. To protect the tax-qualified status of the Plan, the Administrative Committee may ask the eligible employee to provide an opinion of counsel or other evidence to establish that the requirements for a traditional rollover have been satisfied.

e. Matching Contributions

After one year of service, ASB matches employee 401(k) contributions at the rate of 100% of the first 4% of eligible compensation deferred. These matching contributions are known as “AmeriMatch” contributions. For AmeriMatch contributions, compensation is defined in the same way it is defined for 401(k) contributions as described in Note 1.c. above; however, compensation earned prior to an employee becoming eligible for AmeriMatch is not included.

For 2019, ASB made AmeriMarch contributions to the Plan of $2,509,078.

f. Employer Discretionary Contributions

The Plan also includes an annual discretionary profit sharing feature (known as “AmeriShare”). All employees employed on the last day of any Plan year are eligible to share in any AmeriShare allocation for that year. Exceptions to the “last-day requirement” are made for those who die, become disabled, or retire during the year. Retirement is defined as termination of employment either after (i) attaining age 65 or (ii) attaining age 55 and completing 10 years of service with ASB, HEI or any HEI subsidiary. On February 12, 2020, ASB approved an AmeriShare contribution equal to 2.43% of 2019 eligible compensation for the 2019 Plan year. This AmeriShare contribution was deposited into eligible participant accounts on February 18, 2020.

For purposes of calculating any AmeriShare contribution, eligible compensation includes an eligible employee’s annual base salary or pay plus commissions paid during the Plan year, but excludes any amounts deferred to the American Savings Bank Select Deferred Compensation Plan or any other nonqualified deferred compensation plan that are not includible in the gross income of the employee for the taxable year.

g. Participant Accounts

Each participant has an individual account in the Plan, which may include one or more subaccounts. Each participant is always 100% vested in his or her total account, including all subaccounts. A participant’s benefits equal the vested balance in the participant’s account at the time of distribution. Each participant’s account is credited with the participant’s elective

Notes to Financial Statements

December 31, 2019 and 2018

contributions, AmeriMatch and AmeriShare contributions, if applicable, rollover contributions, if any, and allocations of Plan earnings and gains or losses (whether realized or unrealized), and charged with an allocation of any administrative expenses paid by the Plan or charged directly to the participant’s account. Administrative expenses, such as recordkeeping expenses, are paid in part through investment level expenses that are borne by participants in proportion to their investments in the designated investment options that generate revenue credits for the Plan. Individual expenses, such as fees associated with loans and distributions, are charged directly to a participant’s individual account. Participant accounts are valued at the end of each day that the New York Stock Exchange is open.

The Plan is intended to be an Employee Retirement Income Security Act (“ERISA”) Section 404(c) plan, under which the fiduciaries of the Plan are relieved of liability for any losses that are the direct and necessary result of a participant’s or beneficiary’s exercise of control over the investments in his or her individual account. Participants are responsible for directing the investment of all amounts in their accounts using investment options offered under the Plan and for the performance of such investments. As of December 31, 2019, the Plan offered various mutual funds and target-date funds and direct investments in HEI common stock. Prior to July 1, 2019, HEI common stock held by the Plan was held in a unitized common stock fund that consisted of shares of HEI common stock and short-term liquid investments (the “HEI Common Stock Fund #2”). The HEI Common Stock Fund #2 was eliminated at the end of June 2019 and was replaced by a new investment structure that permits participants to invest directly in shares of HEI common stock. Participants may change their investment elections at any time. If a participant does not choose an investment option for any portion of the participant’s account, such amounts are automatically invested in the age-appropriate Fidelity Freedom Index Fund or such other investment as the PIC may direct, pending other direction by the participant.

As of December 31, 2019, the portion of the Plan that is invested in HEI common stock is designated as an employee stock ownership plan (“ESOP”). Amounts contributed to the Plan for investment in HEI common stock or transferred to investments in HEI common stock from other investment options become part of the ESOP component of the Plan. At December 31, 2018, the portion of the Plan comprised of the HEI Common Stock Fund #2 was designated as an ESOP. Amounts contributed to the Plan for investment in the HEI Common Stock Fund #2 or transferred to investments in the HEI Common Stock Fund #2 from other investment options became part of the ESOP component of the Plan.

Participants are not required to make any investment in HEI common stock, and there are two limitations on the amount a participant may invest in HEI common stock. First, a participant may not direct more than 20% of any contribution to HEI common stock. Second, participants and beneficiaries are prohibited from making transfers or exchanges from other investment options into HEI common stock if the transfer or exchange would cause the participant’s or beneficiary’s investment in HEI common stock to exceed 20% of the participant’s or beneficiary’s total account balance. Please note that these limitations also applied to the HEI Common Stock Fund #2 prior to its elimination at the end of June 2019.

h. Distributions

Distributions from participants’ accounts are generally made upon retirement, death, permanent disability or other termination of employment. Distributions may be made in a single lump sum, or a retired or terminated participant may elect to receive partial distributions (once per year) until the participant’s account has been distributed in full or the participant

401(k) Plan

Notes to Financial Statements

December 31, 2019 and 2018

elects to receive a single-sum distribution of the remaining account balance. Retired participants may also receive required minimum distributions from the Plan.

Account balances of $5,000 or less are automatically distributed upon termination of employment. Any automatic distribution of more than $1,000 (but not more than $5,000) is made in the form of an automatic direct rollover to an Individual Retirement Account (“IRA”) designated by the Administrative Committee, unless the participant requests a cash distribution or a direct rollover to an IRA or tax-qualified retirement plan of the participant’s choosing.

Distributions with respect to HEI common stock are made in HEI common stock, unless requested in cash. Prior to July 1, 2019, distributions with respect to HEI Common Stock Fund #2 were made in the form of HEI common stock, unless requested in cash. The participant’s account will be reduced by any unpaid note balance at the time of distribution. However, unless rolled over, the balance of the unpaid note will be taxable to the participant.

i. Death Benefits

Upon the death of a participant, the full value of the participant’s vested account balance (reduced by any outstanding loans) is payable as a death benefit to the participant’s designated beneficiary.

j. Withdrawals While Employed

Prior to termination of employment, a participant may request a withdrawal from his or her account in the event of hardship.

Participants who elect to invest in HEI common stock or elected to invest in the HEI Common Stock Fund #2, prior to its elimination at the end of June 2019 (the ESOP component of the Plan) may elect to receive cash distributions of periodic dividends attributable to such investments or may elect to have such dividends reinvested through the Plan.

A participant who is age 59½ or older may elect to receive an in-service distribution from his or her vested account balance once per year.

k. Notes Receivable from Participants

Participants may borrow from their accounts. All loans must be on commercially reasonable terms and be evidenced by a note. The minimum note amount is $1,000, and the maximum amount of all notes under the Plan is limited to the lesser of $50,000, reduced by the highest outstanding note balance during the prior 12 months minus the outstanding note balance from the Plan on the date the note is made, or 50% of the participant’s vested account balance. The term of a note generally may not exceed 5 years, except that a note used to purchase a principal residence may have a term of up to 15 years. The interest rate on a note is set at the time a participant applies for the note. The interest rate for 2019 and 2018 was 2 percentage points above the Federal Reserve prime rate of interest as of the last working day of the month preceding the month the note was made. All outstanding notes are collateralized by 50% of the participant’s vested account balance, determined when a note is approved. No allowance for credit losses has been recorded as of December 31, 2019 or 2018. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be in default, the default will be a deemed distribution. However, the participant’s account will not be reduced until a distributable event occurs under the terms of the Plan. Notes outstanding at December 31, 2019 bear interest at various rates ranging from 4.25% to

Table of Contents

American Savings Bank

401(k) Plan

Notes to Financial Statements

December 31, 2019 and 2018

9.25%. Principal and interest payments are made ratably through payroll deductions. Participants are allowed up to two notes outstanding at any one time from the Plan.

l. Vesting

Participants are 100% vested in their account balances at all times.

2. Summary of Significant Accounting Policies

a. Basis of Accounting

The Plan prepares its financial statements under the accrual method of accounting.

b. Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Plan Administrator to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

c. Investment Valuation and Income Recognition

The Plan’s investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The PIC is responsible for the Plan’s valuation principles and utilizes information provided by the Plan’s investment advisors and trustee. See Note 3 for a discussion of fair value measurements. Net appreciation or depreciation in the fair value of investments includes realized and unrealized changes in the values of investments bought, sold and held during the year.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

d. Notes Receivable from Participants

Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Interest income is recorded on the accrual basis. Related fees are recorded as administrative expenses and are expensed when they are incurred. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be in default, the participant loan balance is treated as a deemed distribution. However, the participant’s account will not be reduced until a distributable event occurs under the terms of the Plan.

e. Payment of Benefits

The Plan records benefits when they are paid.

f. Expenses

Certain expenses of maintaining the Plan, such as legal, audit, consulting and recordkeeping fees, are paid directly by the Bank and are excluded from these financial statements. Fees related to the administration of notes receivable from participants and distributions are charged directly to the participant’s account and are included in administrative expenses. Investment related expenses are included in net appreciation in fair value of investments.

Notes to Financial Statements

December 31, 2019 and 2018

g. Risks and Uncertainties

The Plan may invest in various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and such changes could materially affect the amounts reported in the Statements of Net Assets Available for Benefits.

At both December 31, 2019 and 2018, approximately 10% of the Plan’s net assets available for benefits consisted of HEI common stock and HEI common stock in the HEI Common Stock Fund #2.

h. Recent Accounting Pronouncements

During 2019, the Plan adopted Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU No. 2016-01 amended ASC 825, Financial Instruments, and eliminated disclosure of the fair value of financial instruments not recorded at fair value previously required under ASC 825. This standard was adopted retrospectively and had no impact on the Plan’s net assets or changes in net assets.

During 2019, the Plan adopted ASU No. 2017-06, Employee Benefit Plan Master Trust Reporting, on January 1, 2019. ASU No. 2017-06 removes the requirement to disclose the percentage interest in the master trust for plans with divided interests and requires that all plans disclose the dollar amount of their interest in each of those general types of investments. ASU No. 2017-06 also requires all plans to disclose (1) their master trust’s other asset and liability balances and (2) the dollar amount of the plan’s interest in each of those balances. The standard was adopted retrospectively and had no impact on the Plan’s net assets or changes in net assets.

In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-13, Disclosure Framework: Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates the disclosure requirement of the amount of, reasons for and policy on transfers between Level 1 and Level 2 of the fair value hierarchy and modifies certain disclosure requirements related to Level 3 recurring and nonrecurring fair value measurements. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Plan is evaluating the impact of the new standard; however, the adoption of this standard is not expected to have a material effect on the Plan’s financial statements.

i. Subsequent Events

The Plan has implemented certain provisions introduced by the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) and the Setting Every Community Up for Retirement Enhancement Act 2019 (the “SECURE Act”), which laws change the Plan to, among others, allow certain eligible individuals to receive coronavirus-related relief for loan repayment, suspend required minimum distributions, and delay the commencement date for requirement minimum distributions. The Plan has implemented CARES Act Distributions, CARES Act Loan Program, and Loan Deferments. Written amendments to the Plan to reflect the operational changes will be adopted at a later date in accordance with applicable law and IRS guidance. No other subsequent events were identified through June 26, 2020, the date these financial statements were issued.

3. Fair Value Measurements

a. Fair Value of Financial Instruments

The following is a description of the valuation methodologies used for assets measured at fair value:

Mutual Funds

Valued using a market approach based on the daily closing price as reported on the active market in which the fund is traded. Mutual funds held by the Plan are open-end mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily Net Asset Value (“NAV”) and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded.

HEI Common Stock

Valued using a market approach based on the daily closing price as reported on the active market in which the stock is traded. The HEI common stock held by the Plan is deemed to be actively traded.

HEI Common Stock Funds

Prior to July 1, 2019, the ASB 401(k) Plan and the Hawaiian Electric Industries Retirement Savings Plan (the “HEIRS Plan”) each maintained a separate unitized employer stock fund in the Master Trust. The HEI Common Stock Funds invested primarily in shares of HEI common stock with a fractional amount invested in interest-bearing cash equivalents and were valued at NAV using the market approach based on: (1) the closing price of the underlying HEI common stock held by the HEI Common Stock Funds and (2) the underlying cash equivalent investments in money market mutual funds valued at NAV. The HEI Common Stock Funds traded daily without any prior redemption notice period (see Note 4 for further discussion of the interest in Master Trust).

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values, which may be materially affected by market conditions and other circumstances. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

b. Fair Value Hierarchy

Accounting Standards Codification 820, Fair Value Measurements and Disclosures, provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The following are the three levels of the fair value hierarchy under this standard:

Level 1 Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Plan has the ability to access at the measurement date.

Level 2 Inputs are quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices that are observable for the asset or liability; or inputs that are derived

Table of Contents

American Savings Bank

401(k) Plan

Notes to Financial Statements

December 31, 2019 and 2018

principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 Inputs are unobservable inputs for the asset or liability.

The level in the fair value hierarchy within which a fair measurement in its entirety falls is based on the lowest level of input that is significant to the fair value measurement in its entirety.

4. Interest in Master Trust

All the invested assets of the HEIRS Plan are held together with all the invested assets of the ASB 401(k) Plan in a master trust (the “Master Trust”) pursuant to a Master Trust Agreement between HEI and American Savings Bank, F.S.B. and Fidelity Management Trust Company (the “Trustee”). Each participating plan has a divided interest in the mutual funds, and HEI common stock or its respective HEI Common Stock Fund in the Master Trust.

Through June 30, 2019, there were two HEI Common Stock Funds. The HEI Common Stock Fund was available only to the participants of the HEIRS Plan, and the HEI Common Stock Fund #2 was available only to the participants of the ASB 401(k) Plan.

The value of the Plan’s interest in the Master Trust is based on the beginning of the year value of the Plan’s interest in the Master Trust plus actual contributions, transfers and allocated investment income or loss less actual distributions and allocated administrative expenses. Investment income and administrative expenses relating to the Master Trust are allocated to the individual plans based upon the daily valuation of the balances invested by each plan.

The net assets of the Master Trust and the Plan’s interest in the Master Trust net assets were as follows:

	2019
December 31	Master Trust		Plan Interest in the Master Trust
Mutual funds	$	691,868,782	$	144,387,839
HEI common stock	105,109,717		16,667,054
Net assets of the Master Trust	$	796,978,499	$	161,054,893

	$	563,569,821	$	86,182,770	$	649,752,591

Transfers between levels are recognized at the actual date of the event or circumstance that caused the transfer. There were no transfers between levels of the fair value hierarchy during 2019.

6. Federal Income Taxes

The Plan and Master Trust are qualified under the Internal Revenue Code (“Code”) and are exempt from federal income taxes under Sections 401(a) and 501(a) of the Code. On October 22, 2013, the Internal Revenue Service (“IRS”) issued the latest favorable determination letter covering the Plan. This latest determination letter does not cover amendments made to the Plan since January 1, 2013. Because of changes in the IRS’s determination letter program, ASB will not be able to apply for periodic determination letters in the future. ASB and its outside ERISA/tax counsel believe that the amendments made since January 1, 2013 meet applicable federal tax law requirements.

ASB is not aware of any Code or ERISA violations that would jeopardize the Plan’s tax exempt status and, as of December 31, 2019 and 2018, has concluded that there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability or disclosure in the financial statements. The Plan is periodically audited by the IRS and the U.S. Department of Labor; however, there are currently no audits in progress. ASB believes that the Plan is no longer subject to income tax examinations for tax years prior to 2016.

7. Party-in-Interest Transactions

Certain Plan investments represent shares of mutual funds managed by Fidelity Management and Research Company (“FMR”). Fidelity Management Trust Company (“FMTC”), an affiliate of FMR, is the Trustee of the Plan, and therefore, transactions with FMR qualify as party-in-interest transactions under the prohibited transaction rules of ERISA for which a prohibited transaction exemption exists.

Effective January 1, 2012, a revenue credit program (“RCP”) for the Plan was implemented by FMTC under which credits are provided for the payment of expenses. Certain recordkeeping, legal and consulting fees incurred by the Plan are included as administrative expenses in the Statement of Changes in Net Assets Available for Benefits because they are paid through the RCP. During the year ended December 31, 2019, the RCP credits used to pay expenses amounted to approximately $23,100. During the year ended December 31, 2019, fees for recordkeeping services provided by Fidelity Investments Institutional Operations Company, Inc., an affiliate of both FMR and FMTC, amounted to approximately $23,400, and were paid through the RCP, and any amounts owing in excess of the revenue credits were paid by the ASB.

During 2019, Plan participants may elect to invest in HEI common stock or prior to July 31, 2019, the HEI Common Stock Fund #2. Since ASB is a wholly owned, indirect subsidiary of HEI, investments in HEI common stock or the HEI Common Stock Fund #2 are party-in-interest transactions under the prohibited transaction rules of ERISA for which a statutory exemption exists. During the year ended December 31, 2019, the Plan made purchases of approximately 25,600 units of the HEI Common Stock Fund #2 for a total purchase price of approximately $863,000 and sales of approximately 447,000 units of the HEI Common Stock Fund #2 for total sales proceeds of approximately $16.2 million. During the year ended December 31, 2019, the Plan made purchases of approximately 371,000 shares of HEI common stock for a total purchase price of approximately $16.2 million and sales of approximately 15,000 shares of HEI common stock for total sales proceeds of approximately $680,000.
