Cautionary Statement Regarding Forward-Looking Information

This report contains information that may constitute “forward-looking statements.” Generally, the words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “project,” “will” and similar expressions identify forward-looking statements, which typically are not historical in nature. All statements that address operating performance, events or developments that we expect or anticipate will occur in the future—including statements relating to general views about future operating results—are forward-looking statements. Management believes that these forward-looking statements are reasonable as and when made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations or projections. These risks and uncertainties include changes in general economic conditions, competitive conditions in our industry, actions taken by third-party operators, processors and transporters, changes in the availability and cost of capital, operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control, the effects of existing and future laws and governmental regulations, the effects of future litigation, and certain factors described in Part II, “Item 1A. Risk Factors” and elsewhere in this report and in our Annual Report on Form 10-K for the fiscal year ended March 31, 2014, and those described from time to time in our future reports filed with the Securities and Exchange Commission.

1. Organization and Basis of Presentation

Organization

Niska Gas Storage Partners LLC (“Niska Partners” or the “Company”) is a publicly-traded Delaware limited liability company (NYSE:NKA) which independently owns and/or operates natural gas storage assets in North America. The Company operates the AECO Hub™, which consists of the Countess and Suffield gas storage facilities in Alberta, Canada and the Wild Goose and Salt Plains gas storage facilities in California and Oklahoma, respectively. Each of these facilities markets natural gas storage services in addition to optimizing storage capacity with proprietary gas purchases.

At September 30, 2014, Niska Partners had 36,647,511 common units outstanding. Of this amount, 19,147,428 common units are owned by affiliates of Carlyle/Riverstone Global Energy and Power Fund II, L.P. and Carlyle/Riverstone Global Energy and Power Fund III, L.P. (collectively, the “Carlyle/Riverstone Funds”), which include Niska Holdings, L.P. and Niska Sponsor Holdings Coopertief, U.A., along with a 1.87% Managing Member’s interest in the Company and all of the Company’s Incentive Distribution Rights (“IDRs”). Including all of the common units owned by the Carlyle/Riverstone Funds, along with the 1.87% Managing Member’s interest, the Carlyle/Riverstone Funds have a 53.14% ownership interest in the Company excluding the IDRs, which are a variable interest. The remaining 17,500,083 common units, representing a 46.86% ownership interest excluding the IDRs, were owned by the public.

Basis of Presentation

The accounting policies applied in these unaudited interim financial statements are consistent with the policies applied in the consolidated financial statements of Niska Partners and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2014.

In the opinion of management, the accompanying consolidated financial statements of Niska Partners, which are unaudited except for the balance sheet at March 31, 2014 which is derived from audited financial statements, include all adjustments necessary to present fairly Niska Partners’ financial position as of September 30, 2014, the results of Niska Partners’ operations for the three and six months ended September 30, 2014 and 2013, along with its cash flows for the six months ended September 30, 2014 and 2013. The results of operations for the three and six months ended September 30, 2014 are not necessarily representative of the results to be expected for the full fiscal year ending March 31, 2015. The optimization of proprietary gas purchases is seasonal with the majority of the revenues and costs associated with the physical sale of proprietary gas generally occurring during the third and fourth fiscal quarters, when demand for natural gas is typically the strongest.

Pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), the unaudited consolidated financial statements do not include all of the information and notes normally included with financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These consolidated financial statements should be read in conjunction with the consolidated financial statements of Niska Partners and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2014.

2. Commitments and Contingencies

Commitments

Niska Partners has entered into non-cancelable operating leases for office space, land use rights at its operating facilities, storage capacity at other facilities, equipment, and vehicles used in its operations. The remaining lease terms expire between October 2014 and February 2058 and require the payment of taxes, insurance and maintenance by the lessee.

Contingencies

Niska Partners and its subsidiaries are subject to various legal proceedings and actions arising in the normal course of business. While the outcome of such legal proceedings and actions cannot be predicted with certainty, it is the view of management that the resolution of such proceedings and actions will not have a material impact on Niska Partners’ unaudited consolidated financial position or results of operations.

3. Recent Accounting Pronouncement

In May 2014, the Financial Accounting Standards Board adopted Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under the new rules, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects to receive in exchange for the goods or services. The rules also require more detailed disclosures related to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. These rules are effective for interim and annual periods beginning after December 15, 2016. Management is currently evaluating the impact of the pending adoption of ASU 2014-09 on the Company’s consolidated financial statements and has not yet determined the method by which it will adopt the standard in 2017.

4. Property, Plant and Equipment

On July 15, 2014, Niska Partners entered into an agreement with Talisman Energy Canada whereby, for an immaterial amount of consideration, the Company acquired the necessary reservoir, storage and land interests to develop a natural gas storage facility in northwestern Alberta, Canada. If developed, the project will have a working gas storage capacity of approximately 55 billion cubic feet (“Bcf”), expandable up to 70 Bcf (the “Sundance Project”). The requisite underlying regulatory approvals have been obtained from the Alberta Energy Regulator and the Sundance Project has significant access to pipeline infrastructure and the associated western Canadian markets.

5. Debt

Niska Partners’ debt obligations consist of the following:

5. Debt (continued)

Senior Notes due 2019

In March 2014, Niska Partners completed a private placement of senior unsecured notes due 2019 (the “6.50% Senior Notes” or “Notes”) through its subsidiaries Niska Gas Storage Finance Corp. and Niska Gas Storage Canada ULC (together, the “Issuers”). The 6.50% Senior Notes are senior unsecured obligations which are: (1) effectively junior to Niska Partners’ secured obligations to the extent of the value of the collateral securing such debt; (2) equal in right of payment with all existing and future senior unsecured indebtedness of the Company; and (3) senior in right of payment to any future subordinated indebtedness of Niska Partners. The 6.50% Senior Notes are fully and unconditionally guaranteed by Niska Partners and certain of its direct and indirect subsidiaries on a senior unsecured basis, and are: (1) effectively junior to each guarantor’s secured obligations; (2) equal in right of payment with all existing and future senior unsecured indebtedness of each guarantor and (3) senior in right of payment to any future subordinated indebtedness of each guarantor.

Interest on the 6.50% Senior Notes is payable semi-annually on October 1 and April 1, commencing on October 1, 2014, and will mature on April 1, 2019. As of September 30, 2014, the estimated fair market value of the Notes was $510.3 million.

Prior to October 1, 2016, the Company has the option to redeem up to 35% of the aggregate principal amount of the 6.50% Senior Notes using net cash proceeds from certain equity offerings at a price of 106.5% plus accrued and unpaid interest. The Company may also redeem all or a part of the 6.50% Senior Notes at redemption prices (expressed as percentages of principal amount) equal to 103.25% during the twelve-month period beginning on October 1, 2016, 101.625% during the twelve-month period beginning on October 1, 2017 and during the twelve month period beginning October 1, 2018 thereafter at par, plus accrued and unpaid interest. The Company is not required to make mandatory redemptions or sinking fund payments with respect to the 6.50% Senior Notes.

The indenture governing the 6.50% Senior Notes limits Niska Partners’ ability to pay distributions in respect of, repurchase or pay dividends on its membership interests (or other capital stock) or make other restricted payments. The limitation changes depending on a fixed charge coverage ratio, which is defined as the ratio of consolidated adjusted earnings before interest, taxes, depreciation and amortization to fixed charges, each as defined in the indenture governing the 6.50% Senior Notes, and measured for the preceding four quarters.

If the fixed charge coverage ratio is not less than 1.75 to 1.0, Niska Partners is permitted to make restricted payments if the aggregate restricted payments since the date of closing of our IPO, excluding certain types of permitted payments, are less than the sum of a number of items including, most importantly:

·                  operating surplus (defined similarly to the definition in our Operating Agreement) calculated as of the end of our preceding fiscal quarter; and

·                  the aggregate net cash proceeds received as a capital contribution or from the issuance of equity interests.

If the fixed charge coverage ratio is less than 1.75 to 1.0, Niska Partners is permitted to make restricted payments if the aggregate restricted payments since the date of closing of its IPO, excluding certain types of permitted payments, are less than the sum of a number of items including, most importantly:

·                  $75.0 million; and

·                  the aggregate net cash proceeds received as a capital contribution or from the issuance of equity interests.

As of September 30, 2014, the fixed charge coverage ratio was 2.6 to 1.0 and the indenture governing the Notes would have permitted the Company to distribute approximately $373.4 million. The fixed charge amount used in the calculation of fixed charge coverage ratio was calculated on a pro-forma basis, taking into account the redemption of the 8.875% Senior Notes due 2018 as if the redemption had occurred on April 1, 2013. The indenture does not prohibit certain types or amounts of restricted payments, including a general basket of $75.0 million of restricted payments.

5. Debt (continued)

Senior Notes due 2019 (continued)

The indenture governing the Notes contains certain other covenants that, among other things, limit Niska Partners and certain of its subsidiaries’ ability to:

·                  incur additional debt or issue certain capital stock;

·                  pay dividends on, repurchase or make distributions in respect of its capital stock or repurchase or retire subordinated indebtedness;

·                  make certain investments;

·                  sell assets;

·                  create liens;

·                  consolidate, merge, sell or otherwise dispose of all or substantially all of its assets;

·                  enter into certain transactions with its affiliates; and

·                  permit restrictions on the ability of its subsidiaries to make distributions.

The occurrence of events involving the Company or certain of its subsidiaries may constitute an event of default under the indenture. Such events include failure to pay interest, principal, or the premium on the notes when due; failure to comply with the merger, asset sale or change of control covenants; certain defaults on other indebtedness; and certain insolvency proceedings. In the case of an event of default, the holders of the notes are entitled to remedies, including the acceleration of payment of the notes by request of the holders of at least 25% in aggregate principal amount of the notes, and any action by the trustee to collect payment of principal, interest or premium in arrears.

Upon the occurrence of a change of control together with a decrease in the ratings of the 6.50% Senior Notes by either Moody’s or S&P by one or more gradations within 90 days of the change of control event, Niska Partners must offer to repurchase the Notes at 101% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to the date of repurchase.

The Company’s ability to repurchase the 6.50% Senior Notes upon a change of control will be limited by the terms of its debt agreements, including its asset-based revolving credit facility. In addition, the Company cannot assure that it will have the financial resources to repurchase the Notes upon a change of control.

$400 Million Credit Agreement

Niska Partners, through its subsidiaries, Niska Gas Storage US, LLC and AECO Gas Storage Partnership, has senior secured asset-based revolving credit facilities, consisting of a U.S. revolving credit facility and a Canadian revolving credit facility, both of which are governed by a credit agreement (the “Credit Agreement” or the “$400 million Credit Agreement”). Each revolving credit facility matures on June 29, 2016.

As of September 30, 2014, $243.5 million in borrowings, with a weighted average interest rate of 3.61% (March 31, 2014 - $119.5 million of borrowings had a weighted average interest rate of 3.56%), were outstanding under the credit facilities. Amounts committed in support of letters of credit totaled $19.8 million at September 30, 2014 (March 31, 2014 - $4.8 million). Any borrowings under the $400 million Credit Agreement are classified as current.

5. Debt (continued)

$400 Million Credit Agreement (continued)

The Credit Agreement provides that Niska Partners may borrow only up to the lesser of the level of the then current borrowing base or the committed maximum borrowing capacity, which is currently $400.0 million. As of September 30, 2014, the borrowing base collateral totaled $445.2 million.

The $400 million Credit Agreement contains limitations on Niska Partners’ ability to incur additional debt or to pay distributions in respect of, repurchase or pay distributions on its membership interests (or other capital stock) or make other restricted payments. These limitations are similar to those contained in the indenture governing the 6.50% Senior Notes, but contain certain substantive differences. As a result of these differences, the limitations on restricted payments contained in the Credit Agreement should be less restrictive than the limitations contained in the indenture. As of September 30, 2014, Niska Partners was in compliance with all covenant requirements under the indenture governing the 6.50% Senior Notes and the $400 million Credit Agreement.

Niska Partners has no independent assets or operations other than its investments in its subsidiaries. Both the 6.50% Senior Notes and the $400 million Credit Agreement have been jointly and severally guaranteed by Niska Partners and substantially all of its subsidiaries. Niska Partners’ subsidiaries have no significant restrictions on their ability to pay distributions or make loans to Niska Partners and have no restricted assets as of September 30, 2014.

6. Risk Management Activities and Financial Instruments

Risk Management Overview

Niska Partners has exposure to commodity price, foreign currency, counterparty credit, interest rate and liquidity risks. Risk management activities are tailored to the risks they are designed to mitigate.

Commodity Price Risk

As a result of its natural gas inventory, Niska Partners is exposed to risks associated with changes in price when buying and selling natural gas across future time periods. To manage these risks and reduce variability of cash flows, the Company utilizes a combination of financial and physical derivative contracts, including forwards, futures, swaps and option contracts. The use of these contracts is subject to the Company’s risk management policies. These contracts have not been treated as hedges for financial reporting purposes and therefore changes in fair value are recorded directly in earnings.

Forward contracts and futures contracts are agreements to purchase or sell a specific financial instrument or quantity of natural gas at a specified price and date in the future. Niska Partners enters into forward contracts and futures contracts to mitigate the impact of changes in natural gas prices. In addition to cash settlement, exchange traded futures may also be settled by the physical delivery of natural gas.

Swap contracts are agreements between two parties to exchange streams of payments over time according to specified terms. Swap contracts require receipt of payment for the notional quantity of the commodity based on the difference between a fixed price and the market price on the settlement date. Niska Partners enters into commodity swaps to mitigate the impact of changes in natural gas prices.

Option contracts are contractual agreements to convey the right, but not the obligation, for the purchaser of the option to buy or sell a specific physical or notional amount of a commodity at a fixed price, either at a fixed date or at any time within a specified period. Niska Partners enters into option agreements to mitigate the impact of changes in natural gas prices.

6. Risk Management Activities and Financial Instruments (continued)

Commodity Price Risk (continued)

To limit its exposure to changes in commodity prices, Niska Partners enters into purchases and sales of natural gas inventory and concurrently matches the volumes in these transactions with offsetting derivative contracts. To comply with its internal risk management policies, Niska Partners is required to limit its exposure of unmatched volumes of proprietary current natural gas inventory to an aggregate overall limit of 8.0 Bcf. At September 30, 2014, 67.0 Bcf of natural gas inventory was offset with financial contracts, representing 99.1% of total inventory. At March 31, 2014, 18.4 Bcf of natural gas inventory was offset with financial contracts, representing 97.2% of total inventory. As of September 30, 2014 and March 31, 2014, the volumes of inventories which were economically hedged using each type of contract were:

Counterparty Credit Risk

Niska Partners is exposed to counterparty credit risk on its trade and accrued accounts receivable and risk management assets. Counterparty credit risk is the risk of financial loss to the Company if a customer fails to perform its contractual obligations. Niska Partners engages in transactions for the purchase and sale of products and services with major companies in the energy industry and with industrial, commercial, residential and municipal energy consumers. Credit risk associated with trade accounts receivable is mitigated by the high percentage of investment grade customers, collateral support of receivables and Niska Partners’ ability to take ownership of customer owned natural gas stored in its facilities in the event of non-payment. For the six months ended September 30, 2014 and 2013, no doubtful accounts expense was recognized as a result of receivables deemed to be uncollectible. It is management’s opinion that allowance for doubtful accounts of $ nil and $0.4 million were required as of September 30, 2014 and March 31, 2014, respectively, on the Company’s accrued and trade accounts receivable.

The Company analyzes the financial condition of counterparties prior to entering into an agreement. Credit limits are established and monitored on an ongoing basis. Management believes, based on its credit policies, that the Company’s financial position, results of operations and cash flows will not be materially affected as a result of non-performance by any single counterparty. Credit risk is assessed prior to transacting with any counterparty and each counterparty is required to maintain an investment grade rating, provide a parental guarantee from an investment grade parent, or provide an alternative method of financial assurance (letter of credit, cash, etc.) to support proposed transactions. In addition, the Company’s tariffs contain provisions that permit it to take title to a customer’s inventory should the customer’s account remain unpaid for an extended period of time. Although the Company relies on a few counterparties for a significant portion of its revenues, one counterparty making up 61.0% and 35.3% of gross revenues for the six months ended September 30, 2014 and 2013, respectively, is a physical natural gas clearing and settlement facility that requires counterparties to post margin deposits equal to 125% of their net position, which reduces the risk of default.

6. Risk Management Activities and Financial Instruments (continued)

Counterparty Credit Risk (continued)

Exchange traded futures and options comprise approximately 64.9% of Niska Partners’ commodity risk management assets at September 30, 2014. These exchange traded contracts have minimal credit exposure as the exchanges guarantee that every contract will be margined on a daily basis. In the event of any default, Niska Partners’ account on the exchange would be absorbed by other clearing members. Because every member posts an initial margin, the exchange can protect the exchange members if or when a clearing member defaults.

Niska Partners further manages credit exposure by entering into master netting agreements for the majority of non-retail contracts. These master netting agreements provide the Company, in the event of default, the right to offset the counterparty’s rights and obligations.

Interest Rate Risk

Niska Partners assesses interest rate risk by continually identifying and monitoring changes in interest rate exposures that may adversely impact expected future cash flows. At September 30, 2014, Niska Partners was only exposed to interest rate risk resulting from the variable rates associated with its $400 million Credit Agreement of which $243.5 million was drawn.

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. Niska Partners continues to manage its liquidity risk by ensuring sufficient cash and credit facilities are available to meet its operating and capital expenditure obligations when due, under both normal and stressed conditions.

Foreign Currency Risk

Foreign currency risk is created by fluctuations in foreign exchange rates. As Niska Partners conducts a portion of its activities in Canadian dollars, earnings and cash flows are subject to currency fluctuations. The performance of the Canadian dollar relative to the U.S. dollar could positively or negatively affect earnings. Niska Partners is exposed to cash flow risk to the extent that Canadian currency outflows exceed Canadian currency inflows. The Company enters into currency swaps to mitigate the impact of changes in foreign exchange rates. The notional value of currency swaps at September 30, 2014 was $13.9 million (March 31, 2014 - $13.0 million). These contracts expire on various dates from October 1, 2014 through June 1, 2016. Niska Partners has not elected hedge accounting treatment, therefore, changes in fair value are recorded directly in earnings.

7. Fair Value Measurements

The carrying amount of cash and cash equivalents, margin deposits, trade receivables, accrued receivables, trade payables and accrued liabilities reported on the unaudited consolidated balance sheet approximate fair value.

Fair values have been determined as follows for Niska Partners financial assets and liabilities that were accounted for or disclosed at fair value on a recurring basis:

The Company’s derivative assets and liabilities recorded at fair value on a recurring basis have been categorized as Level 2. The determination of the fair value of assets and liabilities for Level 2 valuations is generally based on a market approach. The key inputs used in Niska Partners’ valuation models include transaction-specific details such as notional volumes, contract prices and contract terms as well as forward market prices and basis differentials for natural gas obtained from third-party service providers (typically the New York Mercantile Exchange, or NYMEX). There were no changes in Niska Partners’ approach to determining fair value and there were no transfers out of Level 2 during the periods ended September 30, 2014 and March 31, 2014.

The fair value of debt is the estimated amount the Company would have to pay to transfer its debt, including any premium or discount attributable to the difference between the stated interest rate and market rate of interest at the balance sheet date. Fair values are supported by observable market transactions when available.

8. Members’ Equity

Equity Restructuring

On April 2, 2013, Niska Partners completed an equity restructuring with affiliates of the Carlyle/Riverstone Funds. In the restructuring, all of the Company’s 33.8 million subordinated units and previous incentive distribution rights (all of which were owned by the Carlyle/Riverstone Funds) were combined into and restructured as a new class of incentive distribution rights. The equity restructuring, which did not require any further consents or approvals, was effective as of the same day. The transaction was unanimously approved by the Company’s Board of Directors on the unanimous approval and recommendation of its Conflicts Committee, which is composed solely of independent directors.

The restructuring permanently eliminated all of the Company’s subordinated units and previous incentive distribution rights in return for the IDRs. Prior to completion of the restructuring, the Company would have been required to pay the full minimum quarterly distribution of $0.35 per unit on the subordinated units (requiring additional distributions of approximately $12 million per quarter) prior to increasing the quarterly distribution on common units. Quarterly distributions on the subordinated units had not been paid since the quarter ended September 30, 2011.

The IDRs entitle the Carlyle/Riverstone Funds to receive 48% of any quarterly cash distributions after Niska Partners’ common unit holders have received the full minimum quarterly distribution ($0.35 per unit) for each quarter plus any arrearages from prior quarters (of which there are currently none). The previous incentive distribution rights entitled the Carlyle/Riverstone Funds to receive increasing percentages (ranging from 13% to 48%) of incremental cash distributions after the unit holders (both common and subordinated) exceeded quarterly distributions ranging from $0.4025 per unit to $0.5250 per unit. In addition, for a period of five years, and provided that the Carlyle/Riverstone Funds continue to own a majority of both the managing member and the IDRs, the Carlyle/Riverstone Funds will be deemed to own 33.8 million “Notional Subordinated Units” in connection with votes to remove and replace the managing member. These Notional Subordinated Units are not entitled to distributions, but preserve the Carlyle/Riverstone Fund’s voting rights with respect to removal of the managing member.

Distribution Reinvestment Plan

During the six months ended September 30, 2014, unitholders, substantially all of which were comprised of the Carlyle/Riverstone Funds, elected to participate in the distribution reinvestment plan and were issued 902,451 common units in lieu of receiving cash distributions of $12.9 million.

Class D Partnership Units

On May 7, 2014, Niska Holdings L.P. (the “Sponsor Partnership”), the parent of Niska Sponsor Holdings Coöperatief U.A.
