REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 


To the Investment Committee of the
Vectren Corporation Retirement Savings Plan:

We have audited the accompanying statements of net assets available for benefits of the Vectren Corporation Retirement Savings Plan as of December 31, 2005 and 2004 and the related statements of changes in net assets available for benefits for each of the three years ended December 31, 2005. 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 standards of the Public Company Accounting Oversight Board (United States). Those 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 has determined that it is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. An audit includes 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 includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes 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 Vectren Corporation Retirement Savings Plan as of December 31, 2005 and 2004, and the changes in net assets available for benefits for each of the three years ended in the period ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America.

Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held at end of year is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the United States Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

VECTREN CORPORATION

RETIREMENT SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS


1.    
DESCRIPTION OF THE PLAN

a.  General

The Vectren Corporation Retirement Savings Plan (the Plan) is a defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA) as amended. The Plan's sponsor, Vectren Corporation (Vectren or the Company), serves as the plan administrator. Vectren, an Indiana corporation, is an energy holding company headquartered in Evansville, Indiana. An Investment Committee has been appointed by the Company’s Board of Directors to administer the Plan. The following description of the Plan provides only general information. Further details of the Plan are provided in the Summary Plan Description which has been distributed to all plan participants.

Substantially all of Vectren’s wholly owned subsidiaries participate in the Plan.

b.  Participation
 
Non-bargaining unit employees who have completed at least one hour of service and who are expected to complete 1,000 hours of service during their first year of employment are eligible to participate in the Plan. Non-bargaining unit employees who are not expected to meet the 1,000 hours of service threshold are eligible to participate after completing one year of Period Service, as defined in the Plan document.
 
Bargaining unit employees must have either completed 1,000 hours of service or completed one year of service to participate in the Plan.
 
Each participant’s account is adjusted daily for contributions, withdrawals, distributions, income earned, changes in the value of trust fund assets, and expenses directly related to investment transactions. Adjustments are based on participant earnings or account balances, as defined.
 
c.  Contributions and Vesting
 
Contributions are subject to maximum limitations as defined in the Internal Revenue Code and are invested in 5% increments in the Vectren Corporation Common Stock Fund, a common trust fund, and seventeen mutual funds, as directed by participants. Plan participants may elect to contribute from 1% to 50% in whole percentages, of their eligible compensation, as defined in the amended and restated plan document. Employees who become eligible to participate in the Plan subsequent to December 1, 2004 automatically have 3% of their eligible compensation contributed to the Plan. Such contributions are invested in fund options that consider the participants’ estimated retirement date. The participant has the option to elect any other contribution percentage, including zero percent, and any other investment option.

Additionally, bargaining unit participants may contribute 100% of any pay out under their performance incentive plan and any guaranteed annual payment earned by the employee. Participants may also contribute amounts representing distributions from other qualified defined benefit and defined contribution plans. Contributions are subject to limitations established by federal law. All participant contributions are fully vested.

Table of Contents
Non-Bargaining Employees
Generally, the Company matches 50% of the first 6% of eligible compensation contributed by all non-bargaining unit employees. Most participants also receive an additional 3% contribution on eligible compensation; however, certain participants in the Plan prior to March 30, 2000 declined the additional 3% contribution in lieu of rights available under other qualified retirement plans. Certain employees of Vectren’s nonregulated operations also do not receive the additional 3% contribution. Participants vest ratably in 20% increments over five years in employer matching contributions and cliff vest at the end of five years in the additional 3% contribution.

Bargaining Unit Employees
The Company’s matching contribution depends on the negotiated collective bargaining arrangement, but is generally 50% of the first 3% or 4% of eligible compensation. The Company's matching contribution for bargaining unit employees covered under the Utility Workers Union of America, Local 175 (UWUA) agreement is limited to $1,000 per year. Additionally, the Company will contribute an annual contribution for employees covered under the UWUA, which increases annually, as defined in the Plan document ($1,500 in 2005 and $1,300 in 2004). Vesting in employer contributions also depends on the collective bargaining arrangement. Some arrangements vest in employer contributions at the end of five years of service while others vest ratably in 20% increments over five years.
 
d.  Distributions
 
Upon termination, retirement, or disability, participants have the option to receive either a lump sum distribution equal to the value of their vested account balance, or periodic installments over a period not to exceed 10 years, unless benefits are less than $5,000. If benefits are less than $5,000, participants are required to receive a lump sum distribution. Also, if a lump sum distribution is received, the participant or beneficiary may elect to receive their existing investments in the Vectren Corporation Common Stock Fund in whole shares with fractional shares paid in cash.

Upon death of a participant, the beneficiary will continue to receive benefits if the participant was already receiving benefit payments. If the participant had not begun receiving benefit payments, the beneficiary will receive a lump sum distribution of the participant's account balance within 5 years of the participant's death unless an election was made to distribute the participant's account balance in equal installments over a period not greater than 10 years to the beneficiary. If the beneficiary is the participant's spouse, an election can be made not to begin distributions before the participant would have reached age 70-1/2.

e.  Forfeited Accounts

Forfeited non-vested accounts are used to reduce future employer contributions. At both December 31, 2005 and 2004, the amount of forfeited non-vested accounts was not significant.
 
f.  Withdrawals While Employed
 
Once an employee reaches age 59-1/2 and has completed 5 years of service, the employee can withdraw the partial or full value of his/her account at any time without penalty.

Prior to age 59-1/2, an employee can withdraw employee contributions and employer matching and discretionary contributions if the employee satisfies certain hardship requirements as defined in the Plan. The distribution can be the amount necessary to satisfy the immediate financial need of the participant and is only available after the participant has obtained all other distributions and loans available under the Plan.

Table of Contents
g.  Participant Loans
 
The Plan allows eligible participants to borrow up to 50% of the vested amount of their account balance up to $50,000 with a minimum borrowing of $1,000. Each loan shall bear interest at a rate determined by the Investment Committee and is collateralized by the participant’s remaining balance in his/her account. The term of the loan is mutually agreed upon by the Investment Committee and the participant. The loan repayment period shall not exceed 5 years, except in instances where the loan proceeds were used to acquire the principal residence of the participant. Each participant for whom a loan is approved will be charged a $50 fee which is deducted from the participant's account and is paid to the Plan Trustee.

A participant may have no more than one active loan outstanding. Loan payments, both principal and interest, shall be reapplied to the participant’s account and reinvested in the applicable fund based on the participant’s current election.
 
h.  Party-in-Interest Transactions
 
The Plan invests in shares of mutual funds managed by T. Rowe Price (the Trustee) and invests in shares of common stock of the Plan’s sponsor, Vectren. Loan origination fees paid by participants of the Plan to T. Rowe Price amounted to $4,400 and $5,200 for the years ended December 31, 2005 and 2004, respectively. Additionally, Vectren performs certain services at no cost to the Plan and pays certain trustee fees and record keeping costs for the benefit of the Plan.
 
i.  Plan Termination
 
While it has not expressed any intention to do so, the Company has the right to terminate the Plan subject to the provisions of ERISA. Upon partial or total termination of the Plan, the participants’ accounts shall become fully vested and non-forfeitable.
 
j.  Voting Rights of Vectren Corporation Common Stock Fund Participants
 
Each participant who has an account balance in the Vectren Corporation Common Stock Fund is entitled to direct the Trustee as to the manner of voting at each meeting of shareholders for all shares of Vectren Corporation common stock (including fractional shares), represented by the value of the participant's interest in the Vectren Corporation Common Stock Fund.

2.    
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
a.  Basis of Accounting
 
The accompanying financial statements of the Plan have been prepared under the accrual method of accounting.
 
b.  Investments
 
Investments are stated at fair value as determined by the Trustee using quoted market prices. Shares of mutual funds are valued at quoted market prices which represent the net asset value of shares held by the plan at year end. Participant loans are valued at cost which approximates fair value. Investment transactions are reported on the trade date. Investment transactions are participant directed. The Plan provides for various investment options in investment securities. Investment securities are exposed to various risks, such as interest rate and market volatility risks. Due to the level of risk associated with investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the Statement of Net Assets Available for Benefits.

Table of Contents
 
c.  Distributions

Distributions to withdrawing participants are recorded when paid.
 
d.  Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management 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.

e.  Impact of New Financial Accounting Standards

FASB Staff Position (FSP) AAG INV-1 and AICPA Statement of Position (SOP) 94-4-1

SOP 94-4, Reporting of Investment Contracts Held by Health and Welfare Plans and Defined-Contribution Pension Plans (SOP 94-4), is amended by FAS AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans (FSP AAG INV-1 and SOP 94-4-1). The financial statement presentation and disclosure guidance in paragraphs 8-11 of FSP AAG INV-1 and SOP 94-4-1 is effective for financial statements for plan years ending after December 15, 2006. The revised definition of fully benefit-responsive in paragraph 7 of FSP AAG INV-1 and SOP 94-4-1 shall be effective for all investment contracts as of the last day of the annual period ending after December 15, 2006. If comparative financial statements are presented, the guidance shall be applied to all prior periods presented. If an investment contract is considered fully-benefit responsive under the revised definition as of the last day of the annual period ending after December 15, 2006, that contract shall be considered benefit-responsive for all periods presented, providing that contract would have been considered fully benefit-responsive in accordance with the then existing provisions of SOP 94-4. The Plan’s management is in the process of evaluating these recently issued pronouncements and has not yet determined their impact on the Plan’s financial statements.

TAX STATUS

The Company received its last determination letter on December 3, 2003, in which the Internal Revenue Service (IRS) stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. In the opinion of the Investment Committee, the Plan is currently designed, and continues to operate, in a manner that qualifies it under Internal Revenue Code Section 401(a) and, therefore, is exempt from income taxes under the provisions of Internal
Revenue Code Section 501(a). Accordingly, no provision for Federal income taxes has been made.
