Report of Independent Registered Public Accounting Firm

To the Administrator and Participants of the
Eversource 401k Plan

We have audited the accompanying statements of net assets available for benefits of the Eversource 401k Plan (the Plan) as of December 31, 2015 and 2014, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). These standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2015 and 2014, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 2 to the financial statements, the Company elected early adoption of ASU 2015-12, which changed the manner in which it accounts for and discloses certain Plan transactions effective January 1, 2014. Our opinion is not modified with respect to this matter.

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2015 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 in the accompanying schedules, 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, the supplemental information in the accompanying schedules is fairly stated, in all material respects, in relation to the financial statements taken as a whole.

Plan Description

On April 30, 2015, the legal name of Northeast Utilities was changed to Eversource Energy (Eversource).  Effective July 1, 2015, the legal name of Northeast Utilities Service Company was changed to Eversource Energy Service Company (Eversource Service).  Also effective July 1, 2015, the legal name of the Northeast Utilities Service Company 401k Plan was changed to the Eversource 401k Plan (the Plan).

Eversource Service, on its behalf and that of other participating subsidiaries of Eversource (together, the Company), established the Plan on January 1, 1985, to provide a convenient method for Company employees to save for their retirement on a regular and long-term basis.  As of December 31, 2015, all operating companies of Eversource and Eversource Service were participating companies of the Plan.  The following is a brief description of the Plan, which is provided for general information purposes only.  Participants should refer to the Plan document for a more complete description of the Plan's provisions.

General

The Plan is a qualified defined contribution plan subject to the rules and regulations of the Employee Retirement Income Security Act of 1974 (ERISA) that consists of two components: a profit-sharing plan qualified under Section 401(a) of the Internal Revenue Code (IRC) with a cash or deferred arrangement under Section 401(k) of the IRC, and an Employee Stock Ownership Plan (ESOP) within the meaning of Section 4975(e)(7) of the IRC designed to invest primarily in Eversource common shares and intended to qualify under Section 401(a) of the IRC as a stock bonus plan. The participants have the option of receiving distributions upon retirement or termination of employment in the form of cash, in-kind rollovers for Fidelity mutual funds, Eversource common shares, to the extent so invested, and may roll over all or a portion of their Plan balances into an individual retirement account (IRA) or other accepting employer qualified plan and may receive distributions in cash through in-service withdrawals of certain amounts.

The Plan is administered by the Senior Vice President – Human Resources of the Company (the Administrator), who determines eligibility in accordance with Plan documents and makes other interpretations under the Plan at her discretion in conjunction with the Eversource Plan Administration Committee.  The fiduciaries with respect to the Plan are Eversource Service, the Plan Sponsor, the Administrator, the Eversource Investment Management Committee, and the Plan Trustee, as defined below.  The Board of Eversource Service is responsible for determining who has the authority to amend and terminate the Plan and certain other duties.  The Eversource Investment Management Committee is responsible for establishing and implementing Plan investment policies, selecting investment fund options available to participants under the Plan, and monitoring the performance and operations of Plan investment managers and the Plan Trustee.

Plan Description (continued)

General (continued)

Plan investment assets are held in a trust by Fidelity Management Trust Company (Fidelity), the Plan Trustee.  Plan records are maintained by an affiliate of the Trustee, Fidelity Investments Institutional Operations Company, Inc., the Plan record keeper.  The Plan Trustee retains the Plan assets and makes distributions as instructed by the Administrator or its designee.  The Eversource Investment Management Committee is responsible for appointing and removing the Plan Trustee.

Under the Plan, employees may authorize payroll deductions for contributions to the Plan.  An employer matching contribution to the Plan is provided in Eversource common shares (see Contributions, beginning on page 6).  The allocation of Eversource common shares to a participant's account may be made from a combination of Eversource treasury shares and open market repurchases of Eversource common shares.

TRAESOP/PAYSOP

In 1992, the Plan was amended to provide for the merger into the Plan of the Eversource Service Tax Reduction Act Employee Stock Ownership Plan (TRAESOP) and the Eversource Service Payroll-Based Employee Stock Ownership Plan (PAYSOP) Fund, which were two ESOPs for which the applicable tax credits had expired.  Participants' accounts under the TRAESOP and PAYSOP are maintained as separate participant accounts under the Plan.

Dividends

Participants who have holdings in the Eversource Common Share and TRAESOP/PAYSOP Funds in their Plan account can elect to receive dividends paid by these funds on Eversource common shares in cash or continue to have them reinvested automatically in the Plan by allocation of Eversource common shares of equal value.  If a participant holds each of the Eversource share funds, the dividend distribution election applies to all funds.  If no active election is made, dividends will continue to be reinvested.

Plan Description (continued)

Contributions

Participant Contributions:  Under the Plan, active participants may contribute up to 50 percent of annual compensation on a pre-tax basis, an after-tax basis, a Roth basis, or a combination of the three, as defined in the Plan document, and as subject to certain Internal Revenue Service (IRS) limitations.  Employees who have not enrolled in the Plan or who have not elected a zero contribution rate within 60 days from their date of hire, are automatically enrolled in the Plan at a contribution rate of three percent of pre-tax eligible earnings, subject to their modification at any time.

All contributions are invested by the Trustee, as directed by each participant, in one or more investment options of the Plan, including the Eversource Common Shares Fund.  For 2015 and 2014, the maximum combined participant contribution was the lesser of $18,000 and $17,500, respectively, or 50 percent of a participant's pre-tax compensation.  For individuals who are age 50 or older during the 2015 and 2014 calendar years who have made the maximum allowable contribution, a catch-up contribution of an additional $6,000 and $5,500, respectively, was permitted.

Plan participants direct their contributions among various investment options as specified within the Plan documents.

Employer Contributions: For certain eligible employees, based on date of hire, union status, and participating employer, the Plan provides employer matching contributions of either 100 percent up to a maximum of three percent of eligible compensation or 50 percent up to a maximum of eight percent of eligible compensation.  For newly hired employees, the Plan provides employer matching contributions of 100 percent up to a maximum of three percent of eligible compensation, contributed on a pre-tax and/or Roth basis for each employee, as applicable, with at least six months of service, while employees with less than six months of service receive no Company match.  The employer matching contribution is made to the Eversource Common Shares Fund.  Participants are permitted to immediately diversify out of the Eversource Common Shares Fund into other funds within the Plan.

Plan Description (continued)

Contributions (continued)

K-Vantage Contributions:  The Plan provides an enhanced defined contribution feature (referred to as K-Vantage), for eligible employees.  The K-Vantage contribution to the Plan, made on a payroll basis, is age and service based and is the amount of the participant's applicable Plan compensation, as defined by the Plan agreement, multiplied by the applicable percentage, according to the following formula:

Sum of Age and Service Years	Company Contribution
Less than 40 years	2.5% of Plan compensation
40 years or more but less than 60 years	4.5% of Plan compensation
60 years or more	6.5% of Plan compensation

Vesting

A participant is fully vested in his or her own contributions, as well as earnings thereon, immediately upon making the contribution.  Participants are also immediately vested in employer matching contributions plus actual earnings thereon.

Participants who are eligible for K-Vantage vest in K-Vantage contributions plus actual earnings thereon after 3 years of service.  Upon a termination of the Plan, death or disability of the participant, or upon the complete discontinuance of K-Vantage contributions under the Plan, all affected participants will become vested in these contributions in their accounts.

Forfeitures

As of December 31, 2015 and 2014, investments in the Fixed Income Fund option include $2,151 and $10,757, respectively, of forfeitures that may be used to offset future Company contributions to the Plan.  These forfeitures resulted from participants who terminated prior to being vested in the K-Vantage feature.  During 2015 and 2014, the Company used $376,586 and $446,000, respectively, of forfeitures to offset Company contributions to the Plan.

Plan Description (continued)

Benefits

Following termination or retirement, the participant has several options:  participants may defer receipt of any balances in their account up to the time they attain age 70½ if their account balance is greater than $1,000; they can initiate a direct rollover of all or a portion of their account in the Plan to another qualified plan or IRA; or they can request a lump sum disbursement.  Participants who have terminated employment may also take partial distributions.  In-service withdrawals and loans are permitted if certain criteria are met.  

Participant Accounts

Individual accounts are maintained for Plan participants to reflect each participant's share of the Company's contribution, the participant's contribution and the Plan's income according to the participant's investment of his or her own account.  Allocations of income are determined at the participant account level.

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest.  Interest income on notes receivable from participants is recorded when it is earned and was $1.7 million and $1.6 million for the years ended December 31, 2015 and 2014, respectively.  No allowances for credit losses have been recorded as of December 31, 2015 and 2014.  If a participant ceases to make loan repayments and the Administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded.

Subject to certain limitations, participants may apply for loans from their non-ESOP/non-K-Vantage account balances.  Interest on the loan is set at the prime rate plus one percent at the time of borrowing, and the loans are secured by the balance in the participant's account.  Loans are to be repaid within six months to five years (for a general purpose loan) or up to 30 years (for a primary residence loan).

Plan Description (continued)

Termination Provision

Although the Company intends to continue the Plan, Eversource Service may terminate the Plan, and each participating subsidiary of Eversource may terminate its participation in the Plan for any reason, in whole or in part, by action of its Board of Directors.  Upon termination of the Plan or complete discontinuance of contributions hereunder, all affected participants shall become immediately vested in their accounts.  In addition, the Plan recordkeeper shall make a final allocation of Company matching contributions and net earnings/(losses) to the participants after payments of all outstanding claims against the Plan have been made.  Thereafter, the participants shall receive a lump sum payment no later than 60 days after the later of: (1) termination of the Plan or (2) receipt of an IRS determination letter stating that such termination does not adversely affect the qualified status of the Plan.

Summary of Significant Accounting Policies

The financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (GAAP), and in accordance with the rules and regulations of ERISA.  The following is a summary of the significant accounting policies used.

Accounting Standards

Recently Adopted Accounting Standards: In July 2015, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) 2015-12, Plan Accounting – Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965), which eliminates the requirements to measure the fair value of fully benefit-responsive investment contracts and provide the related disclosures about fair value required by Accounting Standard Codification (ASC) 820 Fair Value Measurement and Disclosures (ASC 820).  The ASU clarifies that contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan.  The ASU also eliminates the requirement to disclose net appreciation/depreciation in the fair value of investments by general type, as well as disclosure of individual investments equal to or greater than five percent of net assets available for benefits.  The ASU is effective for fiscal years beginning after December 15, 2015, and the Plan early-adopted the ASU retrospectively.  The accompanying Statements of Net Assets Available for Benefits present the fully benefit-responsive investment contract with the Prudential Insurance Company of America at its contract value, excluding an adjustment from fair value, which was $37.4 million for the year ended December 31, 2014.

Summary of Significant Accounting Policies (continued)

Accounting Standards (continued)

As a result of the adoption of ASU 2015-12, the Investment Contract Held by Insurance Company, a Synthetic Guaranteed Investment Contract (synthetic GIC), is stated separately at contract value within the statements of net assets available for benefits as of both December 31, 2015 and 2014.  

Certain reclassifications of prior period data were made in the accompanying financial statements to conform to the current period presentation as a result of the adoption of new accounting guidance.  See Note 2 "Summary of Significant Accounting Policies - Investments" below, for further information.  

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and short-term cash investments that are highly liquid in nature and have original maturities of three months or less.

Plan Estimates

The preparation of financial statements in conformity with GAAP requires Plan management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of changes in net assets during the reporting period.  Actual results could differ from those estimates.

Investments

Plan investments are stated at fair value (with the exception of the Investment Contract Held by Insurance Company, which is stated at contract value as discussed below).  The fair value of Eversource common shares, investments at registered investment companies, and certain assets in the self-directed Brokerage Link account are based on the closing prices reported on active or non-active markets (see Note 3).  Investments in the Eversource Common Shares Fund are stated at estimated fair values, which have been determined based on unit values.  Unit values are determined by dividing the fund's net assets at fair value by its units outstanding at the valuation dates.  The unit values of the Eversource Common Shares Fund were $79.77 and $83.47 as of December 31, 2015 and 2014, respectively.

Eversource 401k Plan

Notes to Financial Statements (continued)

2.

Summary of Significant Accounting Policies (continued)

Investments (continued)

The accompanying Statements of Changes in Net Assets Available for Benefits include the net appreciation in the fair value of investments, which consists of the realized gains and losses and the unrealized appreciation and depreciation on those investments.  Dividend income is recorded on the ex-dividend date, and interest income is recorded as earned.  Purchases and sales of securities are recorded as of the trade date.

The Plan has investment options for participants, which invest in various securities including registered investment companies, United States government securities, corporate debt instruments, and corporate stocks, including Eversource common shares.  Investment securities, in general, are exposed to various risks, such as interest rate risk, credit risk, and overall market volatility.  Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term, which could materially affect the amounts reported in the financial statements.

Investment Contract Held by Insurance Company and Wrapper Contract: This contract with The Prudential Insurance Company of America is comprised of a mixture of government and non-government bonds, managed to the Barclays Capital Intermediate Government Credit Index, which are placed in a trust (with ownership by the Plan) rather than a separate account of the issuer.  The contract is fully benefit-responsive and provides that participants must execute plan transactions at contract value, and insures the underlying assets at contract value.

The underlying assets of the contract are managed by PIMCO and Jennison Associates and had a contract value of $625.5 million and $659.3 million, respectively, as of December 31, 2015 and 2014.  There are no reserves against contract value for credit risk of the contract issuance or otherwise.  Management believes that the occurrence of events that would cause the Plan to transact at less than contract value are not probable.  The Prudential Insurance Company of America may not terminate the contract at any amount less than contract value.

Fair Value of Financial Instruments

The Plan applies ASC 820, Fair Value Measurement and Disclosures (ASC 820), for all applicable financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis.  ASC 820 defines fair value, establishes a fair value hierarchy, and expands disclosures about fair value measurements.

11

Eversource 401k Plan

Notes to Financial Statements (continued)

Summary of Significant Accounting Policies (continued)

Fair Value of Financial Instruments (continued)

ASC 820 defines fair value as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability.

3.

Fair Value Measurements

The Plan discloses fair value measurements pursuant to a framework for measuring fair value in accordance with GAAP.  The Plan follows a fair value hierarchy that prioritizes the inputs used to determine fair value and requires the Plan to classify assets and liabilities carried at fair value based on the observability of these inputs.  The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.  The three levels of the fair value hierarchy are:

Level 1 - Inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.  Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 - Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs are observable.

Level 3 - Quoted market prices are not available.  Fair value is derived from valuation techniques in which one or more significant inputs or assumptions are unobservable.  The fair values are therefore determined using model-based valuation techniques that include option pricing models, discounted cash flow models, and similar techniques.  

12

Eversource 401k Plan

Notes to Financial Statements (continued)

3.

Fair Value Measurements (continued)

The following tables summarize the fair values and levels within the fair value hierarchy:

Investments in the Eversource Common Shares Fund are stated at estimated fair values, which have been determined based on unit values.  Unit values are determined by dividing the fund's net assets at fair value by its units outstanding at the valuation dates.  These investments have been categorized as Level 2, as all the significant assumptions utilized in determining fair value are observable in the market.  Certain investments classified as registered investment companies have been categorized as Level 2, as such funds invest in companies that have been publically traded for less than five years and have small to medium capitalization.  Certificates of deposit in the Brokerage Link are valued at the balance reported by the issuing bank.  Preferred stock, corporate and government bonds in the Brokerage Link and the intermediate bond fund are valued based on quoted prices in non-active markets.  These investments have been categorized as Level 2.

Investment in Contract Held by Insurance Company is stated at contract value in accordance with ASU 2015-12 and is therefore not included as an investment measured at fair value in the tables above.

Administrative Expenses

The Company pays for certain expenses incurred in the administration of the Plan, with the exception of:

·

Loan initiation fees and various fees associated with the Brokerage Link investment option.  Certain fees are paid by the Plan and/or participants.

·

All investment-related expenses of the Plan, any other expenses of the Trustee necessitated by the terms of any particular investment option, and commissions paid with respect to the purchase or sale of common shares for the Plan.  These expenses are paid by the Plan and participants, as applicable.

The Company, at its discretion, may choose to utilize available forfeiture and/or revenue credits (based on a revenue sharing agreement between Eversource Service and Fidelity) to pay for eligible expenses related to the administration of the Plan, including audit and legal fees.  Credits received under this revenue sharing agreement are recognized as Other Income on the Statements of Changes in Net Assets Available for Benefits and may be used to pay certain eligible Plan expenses, or may be allocated to participant accounts at the discretion of the Administrator or the Plan fiduciaries.

For the years ended December 31, 2015 and 2014, the Company did not pay a material amount of administrative expenses on behalf of the Plan.

5.

Tax Status

The IRS has determined, and informed the Company by a letter dated October 17, 2014, that the Plan and related trust are designed in accordance with applicable sections of the IRC.  The Administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC and that the related trust continues to be tax-exempt.  Therefore, no provision for income taxes has been included in the Plan's financial statements.  The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.  The Plan is no longer subject to income tax examinations for years prior to 2012.

Eversource 401k Plan

Notes to Financial Statements (continued)

Related Parties and Exempt Party-In-Interest

For the years ended December 31, 2015 and 2014, the Plan had investments in 13,647,368 and 14,099,692 common shares of Eversource (within the Eversource Common Shares Fund), respectively, with a cost basis of $557.3 million and $571.4 million, respectively.  For the years ended December 31, 2015 and 2014, the Plan recorded dividend income on common shares of Eversource of $21.8 million and $21.5 million, respectively.

Certain Plan investments are shares of registered investment companies managed by the Trustee.  Therefore, these transactions qualify as exempt party-in-interest transactions.  Fees paid by the Plan for the investment management services amounted to $0.2 million and $0.1 million for the years ended December 31, 2015 and 2014, respectively.

Transactions under the Plan's revenue sharing agreement with the Trustee (Note 4) qualify as party-in-interest transactions.  Amounts earned under this revenue sharing agreement were $1 million for each of the years ended December 31, 2015 and 2014, of which $0.2 million and $0.4 million, respectively, was used to pay eligible plan expenses.

7.

Plan Amendments

Effective July 1, 2015, the Plan was amended to change the legal name of the Plan from the Northeast Utilities Service Company 401k Plan to the Eversource 401k Plan.  The Plan was further amended to replace the words "Northeast Utilities Service Company" with "Eversource Energy Service Company" wherever such words occurred within the Plan document.

Effective January 1, 2015, the Plan was amended to revise the definition of "Compensation" to remove "upgrade pay" as an exclusion from Compensation, as well as to clarify that a Plan loan used to acquire a primary residence shall be repaid within 30 years.
