Report of Independent Registered Public Accounting Firm
 

To the Participants and Administrator of
Northwest Natural Gas Company
Retirement K Savings Plan
 
In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of Northwest Natural Gas Company Retirement K Savings Plan (the “Plan”) at December 31, 2011 and 2010, 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.  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 of these statements in accordance with the 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.  An audit 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, and evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.
 
Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole.  The supplemental schedule; Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2011, 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 Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.  This supplemental schedule is the responsibility of the Plan’s management.  The supplemental schedule has been subjected to the auditing procedures applied in the audit 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.

Northwest Natural Gas Company
Retirement K Savings Plan
Notes to Financial Statements
December 31, 2011 and 2010
 


1.  
 
The following description of the Northwest Natural Gas Company Retirement K Savings Plan (the “Plan”) provides only general information.  Employees and Participants should refer to the Plan document for a more comprehensive description of the Plan’s provisions.
 
General
The Plan is a defined contribution plan covering substantially all employees of Northwest Natural Gas Company (the “Company”).  The eligibility rules and entry dates vary primarily based on the following factors: type of contribution and employment classification (bargaining, non-bargaining, regular, temporary, and term).  At December 31, 2011, 1,157 participants had account balances in the Plan, of which 1,072 were active.
 
The Company is the plan sponsor and administrator.  T. Rowe Price is the Plan’s trustee and performs the recordkeeping duties of the Plan.
 
Contributions
Under the Plan, participants may elect to contribute, subject to Internal Revenue Code (“Code”) limitations, up to 50% of gross pay to the Plan through salary deferral.  For Non-Bargaining Unit employees, the Company matches 60% of the first 6% contributed by each employee, with a maximum match of 3.6% of gross pay.  For Bargaining Unit employees, the Company matches 50% of the first 4% contributed by each employee, with a maximum match of 2% of gross pay.  Each year the Company may make a supplemental contribution, the amount of which will be set by the Company’s Board of Directors.  As of December 31, 2011 and 2010, the Company’s Board of Directors did not declare any supplemental contributions.
 
Non-Contributory Employer Contributions
For all eligible Non-Bargaining Unit employees hired after December 31, 2006, and all eligible Bargaining Unit employees hired after December 31, 2009, the Company will contribute 5% and 4%, respectively, of eligible annual earnings (or another amount fixed annually) as a Non-Contributory Employer Contribution for each year a participant is an active employee of the Company.  These Non-Contributory Employer Contributions are invested in the same funds that have been selected by participants for regular contributions and match, unless an eligible employee has not made an investment election.  In that case, the contribution will be invested in the retirement date based investment fund that has a projected year of retirement which includes the year the participant turns age 65.  In 2011 and 2010, Non-Contributory Employer Contributions totaled $531,563 and $328,449, respectively.
 
Participant Accounts
Where applicable, each participant’s account is credited with Pre-Tax Contributions, Matching Contributions, Supplemental Contributions, Rollover Contributions, Non-Contributory Employer Contributions and net earnings or losses.  Pre-Tax Contributions are based on the participant’s deferral election.  Matching Contributions, Supplemental and Non-Contributory Employer Contributions are credited to the participant’s account according to the formula defined in the Plan document.  Rollover contributions are credited upon receipt from the tax-qualified plan of another employer or from an IRA.  Plan earnings are allocated based on account balances in the investment options selected by the participant and with respect to Non-Contributory Employer Contributions, a retirement date based investment option applicable to the participant under Plan terms.

December 31, 2011 and 2010
 


      Investment Options
Participants may direct contributions in any of the 25 investment options (20 options are funds managed by T. Rowe Price) offered by the Plan.  If an employee that is eligible for Non-Contributory Employer Contributions is not actively participating in the Plan, those contributions will be defaulted into the age-appropriate retirement-date fund until such time as the employee begins participation in the Plan and makes active investment elections.
 
Vesting
All employee contributions, employer match and actual earnings credited to participant accounts are fully vested and nonforfeitable (except for the Non-Contributory Employer Contributions) at all times subject to the limitations imposed by the Code.  Non-Contributory Employer Contributions are subject to a three year cliff vesting schedule with 100% vesting after three years of service.
 
Notes Receivable From Participants
The Plan provides for participant loans under certain guidelines.  Participant loans are repaid through payroll deductions and participants’ remaining account balances are used as collateral for the loans.  The loans bear interest at a rate commensurate with local prevailing rates.  The rate used equals the prime rate plus 1%, based on rates quoted in The Wall Street Journal on the last business day of the month prior to the loan’s inception.
 
Withdrawals and Payment of Benefits
On termination of service due to death, disability, retirement or for other reasons, a participant may receive the value of his or her vested account as a single lump-sum distribution or as two partial lump sum distributions.  Under the hardship withdrawal provisions of the Plan, participants may withdraw salary deferral amounts while still employed by the Company.
 
Administrative Fees and Expenses
Certain expenses of administering and servicing the Plan, including equipment, supplies and payroll expenses of administrative and clerical personnel, and trustee fees are provided by the Company without charge to the Plan.  Loan disbursement fees are paid by the Plan, allocated to participants withdrawing amounts as loans during the year, and are classified as administrative fees and expenses.
 
In 2011, T. Rowe Price credited the Plan with an administrative budget of $176,776, $28,000 of which was used to pay audit fees.  Plan expenses in excess of the budget amount are paid by the Company.
 
Plan Amendments
Effective January 1, 2010 the Plan was amended to add provisions relating to the terms on which Non-Contributory Employer Contributions will be made for certain Bargaining Unit Employees.  In addition, this same amendment added two new affiliates to the Plan: NW Natural Gas Storage LLC and Gill Ranch Gas Storage LLC, and clarified that temporary employees are not common-law employees and are not eligible for the Plan.
 
Effective January 1, 2010, the Plan Recordkeeping Agreement with T. Rowe Price was amended to increase the administrative budget from $20,000 to $75,000 per year.
 
Effective July 22, 2011 within the Distribution of Benefits section within the plan document, age “69” has been replaced with age “70-1/2” to clarify that the required distribution of vested accounts exceeding $5,000 occurs at age 70-1/2 for terminated participants.

Effective August 11, 2011 participants may make in-service withdraws attributable to elective contributions or matching contributions if the participant has reached the age of 59-1/2.  In the original plan document matching contributions could not be withdrawn while employed with the Company unless the participant was 60 years of age with at
least 20 years of service and had not withdrawn matching contributions within the last 5 years.  This amendment was made to simplify the administration.
 
For loans issued after August 11, 2011 the maximum repayment period has been extended from 57 months to 60 months.
 
Effective January 1, 2012 qualified participants will be automatically enrolled in the plan at an elective contribution rate of 4%.  The employee may elect to opt out of the plan or have a different deferral rate.
 
Forfeitures
As of December 31, 2011 and 2010, the remaining forfeiture account balance was $6,214 and $651, respectively.  Forfeitures are used to offset the employer contributions.  Forfeitures of $8,043 and $17,279 for the years ended December 31, 2011 and 2010 were used to offset employer contributions, respectively.
 
2.  
Significant Accounting Policies
 
New Accounting Pronouncements
In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04 Fair Value Measurements and Disclosures (Topic 820) - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS.  This ASU amends current fair value measurement and disclosure guidance to include increased transparency around valuation inputs and investment categorization.  ASU 2011-04 will be effective for the Plan’s 2012 financial statements.  The adoption of this new guidance is not expected to have a material impact on the Plan’s financial statements.
 
In January 2010, the FASB issued updated guidance to improve disclosures regarding fair value measurements.  This update requires entities to (i) disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers and (ii) present separately (i.e. on a gross basis rather than as one net number), information about purchases, sales, issuances, and settlements in the rollforward of changes in Level 3 fair value measurements.  The update requires fair value disclosures by major category rather than by class of assets and liabilities in the statement of net assets available for benefits.  Disclosures regarding the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements for assets and liabilities in both Level 2 and Level 3 are also required.  For all portions of the update except the gross presentation of activity in the Level 3 rollforward, this standard is effective for interim and annual reporting periods beginning after December 15, 2009.  For the gross presentation of activity in the Level 3 rollforward, this guidance is effective for fiscal years beginning after December 15, 2010.  See Note 5 for applicable disclosures.

Basis of Accounting
The financial statements are prepared using the accrual basis of accounting.

Northwest Natural Gas Company
Retirement K Savings Plan
Notes to Financial Statements
December 31, 2011 and 2010
 


Valuation of Investments
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.  See Note 5 for discussion of fair value measurements.
 
Investment Transactions and Net Investment Income Recognition
Securities transactions are recorded on the date the securities are purchased or sold.  Interest income is recorded as earned.  Dividend income is recorded on the ex-dividend date.  The cost of securities sold is determined by the average cost method.
 
The net appreciation (depreciation) in the fair value of investments presented in the statements of changes in net assets available for benefits consists of the realized gains (losses) and the unrealized appreciation (depreciation) on those investments.
 
Notes Receivable From Participants
Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest.  Delinquent notes receivable are reclassified as distributions based upon the terms of the Plan document.
 
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 reported amounts of assets and liabilities at the date of the financial statements and changes therein, and disclosure of contingent assets and liabilities.  Actual results could differ from those estimates.
 
Payment of Benefits
Benefits are recorded when paid.
 
Subsequent Events
The Plan has evaluated events subsequent through the date on which the financial statements were available to be issued.  See Note 10 for a discussion of the Plan’s subsequent events.

5.  
Fair Value
 
In accordance with fair value accounting, the following fair value hierarchy is used for determining inputs for the Plan assets:
 
 
Level 1
Valuation is based upon quoted prices for identical instruments traded in active markets;
 
 
Level 2
Valuation is 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-based valuation techniques for which all significant assumptions are observable in the market; and
 
 
Level 3
Valuation is generated from model-based techniques that use significant assumptions not observable in the market.  These unobservable assumptions reflect our own estimates of assumptions that market participants would use in valuing the asset.
 
When developing fair value measurements, it is policy to use quoted market prices whenever available, or to maximize the use of observable inputs and minimize the use of unobservable inputs when quoted market prices are not available.

Following is a description of the valuation methodologies used for assets measured at fair value.  There have been no changes in methodologies used at December 31, 2011 and 2010.
 
Common Stock
Investments in the Company’s common stock are valued at the closing price on the last day of the year as quoted on the New York Stock Exchange.
 
Mutual Funds
Valued at the net asset value of shares held by the plan at year end.
 
These methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.  Furthermore, although 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.
 
Money Market Fund
The money market fund is not traded in an exchange or active market, however, the fair value is determined based on the net asset value per unit as determined by the fund’s audited financial statements.  There is no restriction in place with respect to daily redemptions of the fund.
 
The following table sets forth the fair value by level, within the fair value hierarchy, the plan’s assets as of December 31, 2011 and December 31, 2010, respectively.

6.  
Termination Provisions
     
In the event of any total or partial termination or discontinuance of the Plan, the accounts of all affected participants shall become fully vested and nonforfeitable (i.e. the Non-Contributory Employer Contribution account).  The Company may continue the trust to pay benefits as they mature, or liquidate and distribute the net assets of the trust among participants and beneficiaries in proportion to their interests.  The Company has no current plans to terminate the Plan.
 
7.  
Related-Party Transactions
 
Since the Company’s common stock is an investment held by the Plan, investments in this common stock represent transactions with parties in interest.  Certain other Plan investments are short-term deposits and investments and shares of mutual funds managed by T. Rowe Price, the trustee, as defined by the Plan.  These Plan investments qualify as parties in interest transactions for which a statutory exemption exists.  The following are related party investments:

8.  
Federal Income Tax Status
 
The Internal Revenue Service has determined and informed the Plan sponsor by a letter dated October 11, 2011, that the Plan is qualified and the trust established under the Plan at the time was tax-exempt, under the applicable sections of the Code.
 
Accounting principles generally accepted in the United States of America require Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS.  The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2011, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the 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 administrator believes it is no longer subject to income tax examinations for years prior to 2009.
 
9.  
Risks and Uncertainties
 
The Plan’s assets are invested, at the discretion of the participants, in various 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 that such changes could materially affect participants’ account balances and the amounts reported in the statement of net assets available for benefits.
 
10.  
Subsequent Events
 
The Plan changed the investment options for participants effective January 1, 2012.  Several T. Rowe Price Funds will not be available and have been replaced with comparable Black Rock Funds.
