EXPLANATORY NOTE

Overview

Active Power, Inc. (the “Company”) is filing this Quarterly Report on Form 10-Q/A (this “Amendment”) to restate and amend the Company’s previously issued unaudited condensed consolidated financial statements and related financial information for the three months ended March 31, 2013 previously included in its Quarterly Report on Form 10-Q for the period ended March 31, 2013 (the “Original Form 10-Q”), which was filed with the Securities and Exchange Commission (“SEC”) on May 3, 2013 (the “Original Filing Date”). This Amendment amends and restates the Company’s unaudited condensed consolidated financial statements and related disclosures in “Part I – Item 1. Financial Statements” for the fiscal quarter ended March 31, 2013, as well as related disclosures in “Part I – Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Part I – Item 4.Controls and Procedures,” “Part II – Item A. Risk Factors” and “Part II – Item 6.Exhibits.”

Other than Footnote 7 to the Company’s unaudited condensed consolidated financial statements included in “Part I – Item 1. Financial Statements” regarding subsequent events and “Part II - Item 1. Legal Proceedings”, generally no attempt has been made in the Form 10-Q/A to modify or update other disclosures presented in the original report on Form 10-Q except as required to reflect the effects of the restatement.  This Form 10-Q/A does not reflect events occurring after the filing of the original Form 10-Q or modify or update those disclosures.  Information not affected by the restatement is unchanged and reflects the disclosures made at the time of the original filing of the Form 10-Q with the SEC on the Original Filing Date.  Accordingly, this Form 10-Q/A should be read in conjunction with the Company’s filings made with the SEC subsequent to the filing of the original Form 10-Q.

Background to the Restatements

On November 4, 2013, the audit committee of the Board of Directors of the Company concluded, in consultation with management and after discussion with the Company’s independent registered public accounting firm (Grant Thornton LLP), that there were certain errors made in the Company’s presentation of revenue, cost of goods sold, accounts receivable and prepaid and other assets in the unaudited condensed consolidated financial statements and related footnotes and disclosures for the fiscal quarters ended March 31, 2013 and June 30, 2013, and accordingly these unaudited condensed consolidated financial statements should no longer be relied upon.

As described further in Note 2 to the Company’s unaudited condensed consolidated financial statements included in “Part I – Item 1. Financial Statements” of this Amendment, the errors relate to certain revenue, costs of goods sold, accounts receivable and prepaid and other assets in the unaudited consolidated statement of operations related to product shipments made to a distributor in China, Qiyuan Network System Limited (“Qiyuan”). As previously disclosed in its September 5, 2013 press release and Form 8-K, the Company announced in error in April 2013 that it had entered into a strategic distribution agreement in China with Digital China Information Service Company Limited (“Digital China”). The actual party to this agreement is Qiyuan. A Company employee in China represented to management that Qiyuan was a subsidiary of Digital China. Management subsequently discovered that the Company employee in China intentionally misrepresented the relationship between Qiyuan and Digital China. Qiyuan has no affiliation with Digital China. Due to this discovery, the Company does not believe the revenue associated with certain shipments in the first quarter of 2013 were reasonably certain of collectability at March 31, 2013, and therefore will restate this revenue and related cost of goods sold, accounts receivable and prepaid and other assets in the quarter ended March 31, 2013. See Note 2 to the Company’s unaudited condensed consolidated financial statements for details around the correction of this error and also see Part I – Item 4.Controls and Procedures for additional information regarding the changes in our disclosure controls and procedures evaluation as a result of this discovery.

1.	Significant Accounting Policies	

Organization and Basis of presentation

Active Power, Inc. and its subsidiaries (hereinafter referred to as “we”, “us”, “Active Power” or the “Company”) manufacture and provide critical power quality and modular infrastructure solutions that provide business continuity and protect customers in the event of an electrical power disturbance. Our products and solutions are designed to deliver continuous clean power, protecting customers from voltage fluctuations, such as surges and sags, and frequency fluctuations, and also to provide ride-through, or temporary, power to bridge the gap between a power outage and the restoration of utility power. Our target customers are those global enterprises requiring “power insurance” because they have zero tolerance for downtime in their mission critical operations. The Uninterruptible Power Supply (“UPS”) products we manufacture use kinetic energy to provide short-term power as a cleaner alternative to electro-chemical battery-based energy. We sell stand-alone UPS products as well as complete continuous power and infrastructure solutions, including containerized continuous power systems that we brand as PowerHouse. We sell our products globally through direct, manufacturer’s representatives, Original Equipment Manufacturer (“OEM”) channels and IT partners. Our current principal markets are North America, Europe Middle East and Africa (“EMEA”), and Asia.

The accompanying condensed consolidated balance sheet as of December 31, 2012, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include the accounts of the Company and its consolidated subsidiaries. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring items) necessary to present fairly the consolidated financial position of the Company and its consolidated results of operations and cash flows. These interim financial statements should be read in conjunction with the financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

2.	Restatement of Previously Reported Unaudited Condensed Consolidated Financial Statements	

The Company has restated its unaudited condensed consolidated financial statements for the three months ended March 31, 2013 due to an error from recognizing revenue prior to when it met full recognition criteria, related to shipments made to Qiyuan, a distributor in China. The error resulted in an overstatement of revenue, cost of goods sold and accounts receivable, while understating prepaid and other assets. The impact on specific items in the condensed consolidated financial statements from correction of the error is shown below in tabular format (unaudited, in thousands):

Index
At March 31, 2013, because collectability was not reasonably assured on shipments to Qiyuan, revenue recognition has been deferred and will be recognized on a cost recovery basis as payments are received. Pending revenue recognition, the costs of goods sold is being reported as a current asset in prepaid expenses and other.

The Company will subsequently recognize $1.6 million in revenue from this distributor in the third quarter of 2013 and an additional $0.2 million in revenue in the fourth quarter of 2013 associated with cash collections on this transaction. The Company also will accept a return of goods back into inventory from this distributor in the fourth quarter of 2013 in the amount of $1.6 million.

Warranty Liability

Generally, the warranty period for our power quality products is 12 months from the date of commissioning or 18 months from the date of shipment from Active Power, whichever period is shorter. Occasionally, we offer longer warranty periods to certain customers. The warranty period for products sold to our primary OEM customer, Caterpillar, is 12 months from the date of shipment to the end-user, or up to 36 months from shipment. This is dependent upon Caterpillar complying with our storage requirements for our products in order to preserve this warranty period beyond the standard 18-month limit. We provide for the estimated cost of product warranties at the time revenue is recognized and this accrual is included in accrued expenses and long-term liabilities on the accompanying consolidated balance sheet.

Revenue Recognition

In general, we recognize revenue when four criteria are met: (i) persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the sales price is fixed or determinable; and (iv) collectability is reasonably assured. Revenue-generating transactions generally fall into one of the following categories of revenue recognition:

 	●	We recognize product revenue at the time of shipment for substantially all products sold directly to customers and through distributors because title and risk of loss pass on delivery to the common carrier. Our customers and distributors do not have the right to return products. If title and risk of loss pass at some other point in time, we recognize such revenue for our customers when the product is delivered to the customer and title and risk of loss have passed.  We may enter into bill-and-hold arrangements and when this occurs delivery may not be present, but other criteria are reviewed to determine the proper timing of revenue recognition.	

 	●	We recognize installation and service and maintenance revenue at the time the service is performed.	

 	●	We recognize revenue associated with extended maintenance agreements (“EMAs”) over the life of the contracts using the straight-line method, which approximates the expected timing in which applicable services are performed. Amounts collected in advance of revenue recognition are recorded as a current or long-term liability based on the time from the balance sheet date to the future date of revenue recognition.	

 	●	We recognize revenue on certain rental programs over the life of the rental agreement using the straight-line method. Amounts collected in advance of revenue recognition are recorded as a current or long-term liability based on the time from the balance sheet date to the future date of revenue recognition.	

 	●	Shipping costs reimbursed by the customer are included in revenue.	

When collectability is not reasonably assured, we defer revenue and will recognize revenue on a cost recovery basis as payments are received.

Multiple element arrangements (“MEAs”) are arrangements to sell products to customers that frequently include multiple deliverables. Our most significant MEAs include the sale of one or more of our CleanSource UPS or PowerHouse products, combined with one or more of the following products: design services, project management, commissioning and installation services, spare parts or consumables, and EMAs. Delivery of the various products or performance of services within the arrangement may or may not coincide. Certain services related to design and consulting may occur prior to delivery of product and commissioning and installation typically take place within six months of product delivery, depending upon customer requirements. EMAs, consumables, and repair, maintenance or consulting services generally are delivered over a period of one to five years. In certain arrangements, revenue recognized is limited to the amount invoiced or received that is not contingent on the delivery of future products and services.

When arrangements include multiple elements, we allocate revenue to each element based on the relative selling price and recognize revenue when the elements have stand-alone value and the four criteria for revenue recognition have been met. We establish the selling price of each element based on Vendor Specific Objective Evidence (“VSOE”) if available, Third Party Evidence (“TPE”) if VSOE is not available, or Best Estimate of Selling Price (“BESP”) if neither VSOE nor TPE is available. We generally determine selling price based on amounts charged separately for the delivered and undelivered elements to similar customers in stand-alone sales of the specific elements. When arrangements include an EMA, we recognize revenue related to the EMA at the stated contractual price on a straight-line basis over the life of the agreement.

Any taxes imposed by governmental authorities on our revenue-producing transactions with customers are shown in our consolidated statements of operations on a net-basis; that is, excluded from our reported revenues.

5.	Fair Value of Financial Instruments	

Our assets and liabilities, which are carried at fair value, are classified in one of the following categories:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than quoted prices in Level 1.

Level 3—One or more significant inputs that are unobservable and supported by little or no market data.

Inputs are referred to as assumptions that market participants would use in pricing the asset or liability. The uses of inputs in the valuation process are categorized into a three-level fair value hierarchy.

Our Level 1 assets and liabilities consist of cash equivalents, which are primarily invested in money-market funds. These assets are classified as Level 1 because they are valued using quoted prices in active markets and other relevant information generated by market transactions involving identical assets and liabilities.

For cash and cash equivalents, accounts receivable, and accounts payable, the carrying amount approximates fair value because of the relative short maturity of those instruments.

6.	Guarantees	

In certain geographical regions, particularly EMEA, we are sometimes required to issue performance guarantees to our customers as a condition of sale. These guarantees usually provide financial protection to our customers in the event that we fail to fulfill our delivery or product warranty obligations. We secure these guarantees with standby letters of credit through our bank. At March 31, 2013 and December 31, 2012, we had $0.1 million and $0 respectively, of performance guarantees outstanding to customers that were secured with letters of credit. The current guarantee is set to expire on September 30, 2013 and there is no foreseeable risk that we will not be able to meet the performance obligations.

7.	Subsequent Events	

On April 30, 2013, we filed a “shelf” registration statement with the United States Securities and Exchange Commission. Under this registration statement, we may, from time to time, sell any combination of the securities described in such registration statement in one or more offerings up to a total dollar amount of $50.0 million. This filing became effective on June 26, 2013.

On April 11, 2013, Lisa Brown resigned as our Vice President of Marketing and Sales Operations.

On September 10, 2013, a purported class action complaint was filed in the United States District Court for the Western District of Texas against the Company and certain of its current and former executives. The case is captioned  Don Lee v. Active Power, Inc., et. al.,  Civil Action No. 1:3-cv-00797. The complaint alleges that on April 30, 2013, the Company announced during a conference call that it had entered into a strategic distribution partnership with Digital China.  However, on September 5, 2013, after the close of trading, the Company disclosed that its partnership was with Qiyuan Network System Limited, which is neither an affiliate nor a subsidiary of Digital China.  The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder, and seeks unspecified damages on behalf of all stockholders.

On September 13 and October 14, 2013, two separate stockholders filed complaints in the District Court of Travis County, Texas purporting to bring derivative actions on behalf of the Company against certain current and former officers and directors of the Company.  The first derivative action is captioned  Okumura v. Almgren, et. al. , Cause No. D-1-GN-13-003230 and the second derivative action is captioned  David B. Shaev IRA v. Milner, et. al. , Cause No. D-1-GN-13-003557.  The allegations of each derivative complaint mirror those of the class action complaint, and they assert claims for breach of fiduciary duty, unjust enrichment, and/or abuse of control and seek damages on behalf of the Company.  Defendants have entered into an agreement with each of the plaintiffs to stay both of the derivative actions pending the outcome of the motion to dismiss in the securities class action described above.

As of November 18, 2013 we cannot assess the potential outcome of these lawsuits.

Overview

Restatement of Previously Reported Condensed Consolidated Financial Information
 
This “Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations” has been amended and restated to give effect to the restatement of our unaudited condensed consolidated financial statements for the three months ended March 31, 2013 due to a correction of errors regarding certain product shipments to a distributor in China. See Note 2 to the unaudited condensed consolidated financial statements in “Part I – Item 1.Financial Statements” of this report for additional information.

Company Overview

Active Power designs and manufactures patented flywheel-based uninterruptible power supply (“UPS”) products and Modular Infrastructure Solutions (“MIS”). These solutions are designed to ensure continuity for data centers and other mission critical operations in the event of power disturbances.

Our products and solutions are designed to deliver continuous conditioned (“clean”) power during power disturbances and outages, voltage sags and surges, and provide ride-through power in the event of utility failure, supporting operations until utility power is restored or a longer term alternative power source, such as a diesel generator, is engaged.  We believe our products offer an advantage over those of our competitors in the areas of power density (less space) and energy efficiency, total cost of ownership, system reliability, modular design, and the economically green benefits of our solutions.

We have sold our patented flywheel-based UPS systems since 1999. Our patented flywheel-based UPS products store kinetic energy by constantly spinning a compact steel wheel (“flywheel”) driven from utility power in a low friction environment. When the utility power used to spin the flywheel fluctuates or is interrupted, the flywheel’s inertia causes it to continue spinning. The resulting kinetic energy of the spinning flywheel generates electricity known as “bridging power” for short periods, until either utility power is restored or a backup electric generator starts and takes over generating longer-term power in the case of an extended electrical outage. We believe our flywheel products provide many competitive advantages over conventional battery-based UPS products, including substantial space savings, higher power densities, “green” energy storage, and higher power efficiencies up to 98%. This high energy efficiency reduces operating costs and provides customers a lower total cost of ownership. We offer our flywheel products with load capabilities up to 8,400kVA. Our flywheel-based UPS systems are marketed under the brand name CleanSource. UPS product revenue may include ancillary components delivered as part of a total UPS solution. As of March 31, 2013, we have shipped more than 3,700 flywheels in UPS system installations, delivering more than 900 megawatts of power to customers in 57 countries around the world, providing nearly 150 million runtime hours of operation. In late 2012, we introduced our next generation CSHD 625kVA and 750 kVA UPS products, which we plan to start distributing in 2013.

Index
We also sell modular power infrastructure solutions, which incorporate our UPS products with other equipment including switchboards, generators and monitoring and analytics tools to provide complete short- and long-term protection in the event of a power disturbance. Where this integrated solution is sold in a containerized package, it is marketed under the brand name PowerHouse. PowerHouse can be deployed in an ISO or purpose built container depending upon location. These systems are specifically designed to handle the demands of the most technically advanced facilities requiring the highest power integrity available while maximizing up-time, useable floor space and operational efficiency. Designed to offer a highly flexible architecture to respond to a customer’s constantly changing environment, our PowerHouse systems are offered in four standard configurations, enabling sizing for infrastructure on demand. These systems are highly differentiated as they offer flexibility in placement, space savings, rapid deployment, high energy efficiency, and just in time use of capital deployment. They also deliver significant value to customers as the entire system is integrated and tested prior to delivery for a repeatable simple solution. We also sell modular power infrastructure solutions to customers in a non-containerized format, typically deploying such solutions inside buildings. We plan to grow revenue in coming years from current and future customers as modular data center infrastructure continues to gain acceptance in the market.

In close cooperation with our strategic partners in the technology industry and leveraging our expertise in containerization and power distribution, in 2010 we began to manufacture modular IT infrastructure solutions, designed to specification for select IT channel business partners.  These solutions serve as the infrastructure for modular data center deployment model and are in themselves self-contained fully-functional data centers.  Modular data centers may be rapidly deployed with other modular infrastructure such as power and cooling to deliver a cost-effective alternative to traditional raised-floor data centers.  Active Power designs and delivers the exterior shell and a fully outfitted interior – including electrical, cooling, monitoring, and other elements – ready for the IT channel partner to add its IT racks and servers.  After the IT channel partner adds its IT equipment to our modular IT infrastructure solution, the IT channel partner has a functional data center ready for deployment at its end-user site.

Finally, we offer services in the form of installation, maintenance, project management, and other professional services. Services are often sold in conjunction with the products above, and are increasingly becoming a larger part of our overall revenue.

Our headquarters are in Austin, Texas, with international offices in the United Kingdom, Germany, and China.

We sell our products to a wide array of commercial and industrial customers across a variety of vertical markets, including data centers, manufacturing, technology, broadcast and communications, financial, utilities, healthcare, government and airports. However, our primary focus is on data center applications within these vertical markets.  We have expanded our global sales channels and direct sales force, selling in major geographic regions of the world, but particularly in North America, Europe and Asia. We sell our products through the following distribution methods:

 	●	sales made directly by Active Power;	

 	●	manufacturer’s representatives;	

 	●	distributors;	

 	●	OEM partners; and	

 	●	strategic IT partners.	

We believe a number of underlying macroeconomic trends place us in a strong position to be one of the leading providers of critical power protection and infrastructure solutions. These trends include:

 	●	the increasing business costs of downtime;	

 	●	a rapidly expanding need for data center infrastructure;	

 	●	ever-increasing demands placed on the public utility infrastructure;	

 	●	an inadequate investment in global utility infrastructure;	

 	●	rising costs of energy worldwide driven by volume of energy used; and	

 	●	an increasing demand for economically green solutions.

Index
We have evolved significantly since the company was founded in 1992.  Our early focus was on research and development of the core products that continue to enable our business today.  Over the past several years, we have focused our efforts on brand, markets, and channels of distribution.  The technological foundation of Active Power has yielded more than 100 worldwide patents and a highly differentiated, cost-efficient product platform that we have evolved into an expanding suite of infrastructure solutions. As we go forward, it is critical for us to focus on both developing technology to maintain and grow our leadership position and expand our addressable markets and on building channels of distribution to have more avenues into the market.

We have developed and implemented a go-to-market strategy to set the direction for our sales and marketing initiatives and plans around the following components:

 	●	Customer:  Data Center Applications Across Vertical Markets	

 	●	Distribution:  Partner Enabled Distribution Strategy Transacted Locally	

 	●	Geography:  Global Markets served from four Centers of Operation	

 	●	Products:  UPS and Modular Infrastructure Systems	

 	●	Value:  Efficient, Reliable, Green Solutions	

 	●	Service: Installation Maintenance, Project Management and Other Professional Services	

As a result of this strategy, we have been successful in improving our operating performance, broadening our global footprint, diversifying our customer base, broadening our sales channels and partners, and moving higher up the customer value chain with innovative developments of our core underlying product technology.

Product revenue.  Product revenue primarily consists of sales of our UPS and MIS products. Our CleanSource power quality products are comprised of both UPS and energy storage product lines and our MIS products consist of our modular power infrastructure solutions, including PowerHouse (which are comprised of our UPS systems and some combination of third party ancillary equipment, such as engine generators and switchgear) and our modular IT infrastructure solutions that provide a combination of power distribution, cooling capabilities, security systems, fire suppression and monitoring capabilities for our business partners. Our product revenue was derived from the following sources:

Total product revenue for the three-month period ended March 31, 2013 decreased by $5.0 million, or 30%, compared to the same period in 2012 and decreased $47,000, or 0%, from $11.5 million in the fourth quarter 2012. The decrease from first quarter 2012 to first quarter 2013 was driven primarily by a decrease in MIS product sales. Product revenue stayed flat from fourth quarter 2012 to first quarter 2013. UPS revenue was up $3.2 million, or 76%, in the first quarter 2013 from the same period in the prior year which partly offset the decline in MIS revenues of $8.2 million, or 67%. UPS revenue increased in first quarter 2013 compared to first quarter 2012 primarily due to a large customer order built and shipped in the fourth quarter of 2012 but recognized in revenue in the first quarter of 2013. We expect product mix to continue to shift as we obtain large customer orders for either UPS or MIS products in any particular quarter.

Product revenue from Active Power branded products through our direct and manufacturer’s representative channels was $8.6 million, or 75% of our product revenue, for the three-month period ended March 31, 2013, compared to $6.3 million, or 39% of our product revenue, in the same period of 2012, and $5.5 million, or 48% of our product revenue, for the fourth quarter of 2012.

Product revenue from our OEM channels for the three-month period ended March 31, 2013 was $2.0 million, an increase of approximately $1.0 million, or 100%, compared to revenue of $1.0 million for the first quarter of 2012. This reflected increased OEM activity in the EMEA market. Product revenue from our OEM channels for the three-month period ended March 31, 2013 increased by $0.3 million, or 20%, compared to $1.7 million for the fourth quarter of 2012. The size and volume of orders from our OEM channels can fluctuate significantly on a quarterly basis and in 2013 we continue to see fewer, but larger value transactions from our OEM channel.  We have supported our OEM partners’ efforts to sell total solutions to their customers that include generators and switchgear that they manufacture along with our UPS products as a total solution. Sales to Caterpillar, our primary OEM channel, represented $2.0 million, or 17% of our product revenue, for the three-month period ended March 31, 2013, compared to $1.0 million, or 9% of our product revenue, in the comparable period of 2012 and $1.7 million, or 14%, in fourth quarter 2012. Caterpillar remains one of our largest UPS customers as well as our largest OEM customer.

Product revenue from our IT channel for the first quarter of 2013 was $0.9 million, compared to $9.0 million for the first quarter of 2012, which represents an $8.1 million, or 90%, decrease, and also decreased $3.4 million compared to the $4.3 million of IT channel revenue from fourth quarter 2012. These decreases were primarily due to a decrease in demand for infrastructure solutions from HP, our largest IT channel partner. Historically, we have manufactured and sold infrastructure solutions to HP, for them to re-sell to end users in conjunction with sales of their IT and computing products. Thus, the level of orders will fluctuate dependent upon our partner’s need for infrastructure solutions. We have historically experienced large quarterly fluctuations in the number and value of such orders. Sales to HP accounted for 3% of our product revenue for the first quarter of 2013 compared to 62% in the same period of 2012.

Our MIS products tend to be larger in value and derive sales from a smaller number of customers compared to sales of our UPS products. This smaller number of customers with greater transaction value can contribute to large quarterly fluctuations in revenue from each product family due to the timing of orders and shipments in any particular accounting period. A small number of transactions can lead to significant revenue, but cause greater volatility in our quarterly results and can increase liquidity risk.  To manage this risk we continue to refine and improve the payment terms of these opportunities as part of our working capital management process.

North America sales were $10.0 million or 88% of our product revenue for the three-month period ended March 31, 2013, compared to $10.6 million, or 65% of our product revenue, for the same period in 2012 and $9.2 million, or 80% of product revenue, in the fourth quarter of 2012. This slight decrease compared to prior year reflects lower MIS revenues which historically have largely originated in the North American market.

We also sell products directly to customers in Asia and EMEA and we have a network of international distributors in these and other territories. In some of these markets, customers are more likely to purchase a total power solution such as PowerHouse from us rather than a stand-alone UPS system. This usually results in a longer selling cycle and makes quarterly results from these regions more inconsistent and dependent upon a smaller number of larger value transactions. Thus, the amount of revenue from our international markets can fluctuate significantly on a quarterly basis. Product sales to customers in Asia were $(0.3) million, or (3)% of our total product revenue, in the three-month period ended March 31, 2013, compared to $1.5 million, or 9%, for the same period in 2012 and $1.0 million, or 8%, for the fourth quarter of 2012. This was primarily driven by reduced orders from distributors in China. See Footnote 2 to the unaudited condensed consolidated financial statements of this Form 10-Q/A for more information regarding adjustments to revenues for the three months ended March 31, 2013 in the Asia region.  Product revenue in EMEA was $1.7 million, or 15% of product revenue, in the three-month period ended March 31, 2013, compared to $4.3 million, or 26%, for the same period of 2012 and $1.3 million, or 12%, for the fourth quarter of 2012. These fluctuations are primarily attributable to variations in sales of our MIS products in each region in the relevant periods and illustrate the impact of larger orders from fewer customers on quarterly revenue for each of these regions. Products may sometimes be shipped outside of the region in which the revenues were generated.

Service and other revenue. Service and other revenue primarily relates to revenue generated from both traditional (after-market) service work and from customer-specific system engineering. This includes revenue from design, installation, startup, repairs or reconfigurations of our products and the sale of spare or replacement parts to our OEM and end-user customers. It also includes revenue associated with the costs of travel of our service personnel and revenues or fees received upon contract deferment or cancellation. Revenue from extended maintenance contracts with our customers is also included in this revenue category.
18

Index
Service and other revenue decreased by approximately $0.4 million, or 12%, for the three-month period ended March 31, 2013, compared to the same period of 2012, and decreased $0.8 million, or 21%, compared to the fourth quarter of 2012. These decreases reflect lower professional fees associated with decreased MIS sales in the March 2013 quarter compared to the prior year and prior quarter sequentially. For our MIS customers, we provide a full power solution, including design services, site preparation, installation of an entire power solution and provision of all products required to provide a turnkey product to the end user, often including maintenance services.  Where we make sales through our OEM channel, it is typical for the OEM to provide these types of services to their end-user customers, so these revenue opportunities do not typically exist for us on our OEM sales. We anticipate that service and other revenue will continue to grow with product revenue, particularly as our PowerHouse system revenue grows and as our installed base of UPS product expands, because as more units are sold to customers, more installation, startup and maintenance services will be required.
 
Cost of product revenue. Cost of product revenue includes the cost of component parts of our products, ancillary equipment that is sourced from external suppliers, personnel, equipment and other costs associated with our assembly and test operations, including costs from having underutilized facilities, depreciation of our manufacturing property and equipment, shipping costs, warranty costs, and the costs of manufacturing support functions such as logistics and quality assurance. The cost of product revenue as a percentage of total product revenue was 70% for the three-month period ended March 31, 2013, compared to 73% for the same period in 2012 and 60% for the fourth quarter of 2012. The decrease in costs as a percentage of revenue compared to first quarter 2012 reflected more favorable product mix and improved UPS pricing arrangements, and an overall lower cost structure compared to 2012 from vendor management programs and other cost management initiatives. The increase in cost of product revenue in first quarter 2013 compared to fourth 2012 is related to less favorable pricing arrangements on UPS systems orders in the first quarter of 2013. We continue to operate a manufacturing facility that has a manufacturing and testing capacity that can be significantly greater than our current product revenue levels in any given quarter, dependent upon the product mix. A large portion of the costs involved in operating this manufacturing facility are fixed in nature and we have incurred unabsorbed overhead each quarter depending on the level of UPS system production. We continue to work on reducing our product costs through design enhancements and modifications and increasing our sales volume to absorb these expenses. We also are working to create cross-functional utilization of our personnel between UPS and MIS product manufacturing so as to obtain higher overall labor efficiency.

Cost of service and other revenue. Cost of service and other revenue includes the cost of component parts that we use in service or sell as spare parts, as well as labor and overhead costs of our service organization.  This includes travel and related costs incurred in fulfilling service obligations to our customers and the costs of third party contractors used in completion of some of our professional services. The cost of service and other revenue was 71% of service and other revenue in the three-month period ended March 31, 2013, compared to 74% for the same period of 2012 and 62% in the fourth quarter of 2012.  The decrease in first quarter 2013 compared to first quarter 2012 reflects a shift in the types of services provided, with professional services being down in first quarter 2013 compared to the same period in 2012. The increase in cost of service and other revenue in first quarter 2013 compared to fourth quarter 2012 is due to an increase in materials costs, which can happen when there is a significant warranty repair. The utilization of our service personnel will also be affected by the number of MIS solution products implemented in a particular period, and in periods where we have a low number of installation projects we would expect our costs as a percentage of revenue to increase due to lower employee utilization. A large portion of the costs involved in operating our service organization are fixed in nature, as we have to maintain a certain level of availability to service our contracted customers rapidly, and depending upon the revenues for the quarter, we may incur unabsorbed overhead in the quarter. We continue to work on reducing our service overhead through better utilization of our service employees and cost control measures. This infrastructure also means that we can leverage this investment and grow our service capabilities substantially by adding direct technical labor only as required.

Gross profit. For the three-month period ended March 31, 2013, our gross profit margin was 30% of revenue, compared to a 27% gross profit margin for the first quarter of 2012 and a 40% gross profit margin for the fourth quarter of 2012. The improvement from the first quarter of 2012 reflects our product mix, as well as overall cost containment initiatives put in place over the last year, and improved UPS pricing arrangements. The decrease in the margin from the fourth quarter of 2012 is related to lower margin orders in the first quarter of 2013 compared to the fourth quarter 2012, of which a high percentage came from distributor channel orders in Asia. We also had an increase of ancillary revenue, which tends to reflect lower overall margins. Our ability to further improve gross margins will depend, in part, on our ability to further improve our sales channel mix, increase sales of higher margin products such as our UPS products, optimize our product pricing, improve our professional service margins through further pricing and operating efficiency, and increase our total revenues to a level that will allow us to improve the utilization of our manufacturing and service operations.

Index
Research and development. Research and development expense primarily consists of compensation and related costs for employees engaged in research, development and engineering activities, third party consulting and development activities, as well as an allocated portion of our occupancy costs. Overall, our research and development expenses were approximately $0.3 million, or 27%, higher in the first quarter of 2013 compared to the first quarter of 2012 and were $0.2 million, or 17%, higher than the fourth quarter of 2012. The increases are primarily due to our next generation of UPS product, which we feel will offer greater power modularity and space efficiencies compared to our existing UPS products, especially as we target the higher power market groups.   As we are in the final phases of testing, as well as optimizing ways to reduce the overall future costs of production, we have had an increase in research and development expenses.  It is anticipated that the new UPS product line will allow improved profit margins and provide a larger addressable market for our UPS systems business.

Selling and marketing. Selling and marketing expense primarily consists of compensation, including variable sales compensation and related costs for sales and marketing personnel, related travel, trade shows and promotional expenses, compensation paid to resellers and agents, an allocated portion of our occupancy and other costs, and the cost of our foreign sales operations. Selling and marketing costs were approximately $0.6 million, or 17%, lower in the first quarter of 2013 compared to the first quarter of 2012 and decreased approximately $0.3 million, or 10%, from the fourth quarter of 2012 primarily from lower employee compensation costs, lower commissions for third party manufacturers’ representatives, as well as lower expenditures on trade shows and travel costs.

General and administrative. General and administrative expense is primarily comprised of compensation and related costs for board, executive and administrative personnel, and professional fees. General and administrative expenses for the first quarter of 2013 decreased approximately $0.4 million, or 27%, compared to the same period in 2012 due to lower stock compensation expense and lower legal fees, all partially offset by an increase in contract labor. General and administrative expenses decreased by approximately $0.6 million, or 33%, compared to the fourth quarter of 2012 primarily due to lower compensation costs.

Interest expense, net. Net interest expense for the first quarter of 2013 decreased by approximately $32,000, or 28%, compared to the first quarter of 2012. We incurred higher interest expense in 2012 as we had a larger average outstanding balance on our revolving credit facility. Our average cash and cash equivalents balance over the three-month period ending March 31, 2013 decreased by $0.7 million, or 5%, compared to the average balance over the same period ending March 31, 2012. Cash was higher in 2012 due to proceeds received from sales of approximately 2.9 million shares of our stock.

Other income. Net other income in the first quarter of 2013 and 2012 primarily reflects foreign exchange gains on a bank account and sales contracts held in foreign currencies.

Liquidity and Capital Resources

Our primary sources of liquidity at March 31, 2013 are our cash and cash equivalents on hand, our bank credit facilities and projected cash flows from operating activities. If we meet our cash flow projections in our current business plan, we expect that we will have adequate capital resources to continue operating our business for at least the next 12 months. Our business plan and our assumptions around the adequacy of our liquidity are based on estimates regarding expected revenues and future costs. However, there are scenarios in which our revenues may not meet our projections, our costs may exceed our estimates or our working capital needs may be greater than anticipated. Further, our estimates may change and future events or developments may also affect our estimates. Any of these factors may change our expectation of cash usage in the remainder of 2013 and beyond or adversely affect our level of liquidity.

A substantial increase in sales of our PowerHouse or our modular IT infrastructure solutions products or a substantial increase in UPS sales may materially impact the amount of liquidity required to fund our operations. The amount of time between the receipt of payment from our customers and our expenditures for raw materials, manufacturing and shipment of products (the cash cycle) for sales of our CleanSource UPS product can be as short as 45 days, and is typically 60 days. However, the cash cycle on a MIS sale can be significantly longer due to a longer lead time needed on materials purchases and a longer manufacturing schedule. We intend to mitigate the financial impact of this longer cash cycle by requiring customer deposits and periodic payments where possible from our customers. This is not always commercially feasible, and in order to increase our MIS sales, we may be required to make larger investments in inventory and receivables. These larger investments may require us to obtain additional sources of working capital, debt or equity financing in order to fund this business.
20

Index
Should additional funding be required, we would expect to raise the required funds through borrowings or public or private sales of debt or equity securities. If we raise additional funds through the issuance of convertible debt or equity securities, the ownership of our stockholders could be significantly diluted. If we obtain additional debt financing, a substantial portion of our operating cash flow may be dedicated to the payment of principal and interest on such indebtedness, and the terms of the debt securities issued could impose significant restrictions on our operations. We do not know whether we will be able to secure additional funding, or funding on terms acceptable to us, to continue our operations as planned. If financing is not available, we may be required to reduce, delay or eliminate certain activities or to license or sell to others some of our proprietary technology.
 
The following table summarizes the quarterly changes in cash used in operating activities:
($ in thousands)	Three Months Ended
March 31,	 	Variance	 	
 	2013	 	2012	 	$	 	 	%	 	
Cash provided by (used in) operating activities	 	$	1,688	 	 	$	(1,904	)	 	$	3,592	 	 	 	189	%	
 
Cash used in operating activities was a positive $1.7 million in the three-month period ended March 31, 2013 compared to a negative $1.9 million the same period of 2012. Changes in the period ending March 31, 2013 were related to changes in our working capital, as were the changes in the prior year quarter as well. Overall ending working capital on the balance sheet was relatively unchanged year over year at March 31.

The fluctuations in working capital can be impacted by the timing of product orders and shipments. In the three-month period ended March 31, 2013, we saw a decrease of approximately $1.6 million in inventory compared to December 31, 2012. This was primarily due to a large order that was received and built in the fourth quarter 2012 that shipped in the first quarter of 2013.  There was also an increase in accounts payable of $0.9 million from December 31, 2012 to March 31, 2013. The large decrease in accounts receivable and increase in prepaid expenses and other in the three months ended March 31, 2013 is largely due to the reclassification of the Qiyuan distributor shipments, as restated in this Form 10-Q/A. We anticipate that cash provided by (used in) operations will fluctuate significantly based upon the volume and size of our modular infrastructure solutions sold and by the timing of product delivery relative to our reporting periods, and that such volatility in sources and uses of funds will continue based upon growth of our modular infrastructure solutions businesses.

The following table summarizes the quarterly changes in cash used in investing activities:
($ in thousands)	Three Months Ended
March 31,	 	Variance	 	
 	2013	 	2012	 	$	 	 	%	 	
Cash used in investing activities	 	$	(214	)	 	$	(495	)	 	$	(281	)	 	 	57	%	

Investing activities primarily consist of purchases of property and equipment. Capital expenditures were $0.3 million, or 53% lower in the three-month period ending March 31, 2013, compared to the same period of 2012, which is attributable to the fact that in the 2012 period we invested in multiple demonstration UPS systems in Asia and EMEA. This year’s expenditures include the purchase of heavy equipment expected to help us make our manufacturing facility more efficient and reduce our rental expenses going forward.

The following table summarizes the quarterly changes in cash provided by financing activities:
($ in thousands)	Three Months Ended
March 31,	 	Variance	 	
 	2013	 	2012	 	$	 	 	%	 	
Cash provided by financing activities	 	$	352	 	 	$	10,048	 	 	$	(9,696	)	 	 	-96	%	

Funds provided by financing activities in the period ending March 31, 2013 primarily includes proceeds received from stock option exercises. Funds provided during the three-months ended March 31, 2012 primarily reflect the sale of common stock of approximately 2.9 million shares at a purchase price of $3.40 per share, for proceeds, net of fees and expenses, of approximately $9.6 million, and also reflects proceeds from the exercise of employee stock options.
21

Index
The shares that were sold in the first quarter of 2012 were sold pursuant to our shelf registration statement on Form S-3 dated November 24, 2009, as amended on December 17, 2009 (Registration No. 333-163301), which was declared effective by the Securities and Exchange Commission (the “SEC”) on December 21, 2009, as supplemented by a prospectus supplement dated March 7, 2012 (the “Offering”).  No discounts or placement agent fees were payable in connection with the Offering.

We believe that our cash and investments, projected cash flows from operations and our sources of available liquidity will be sufficient to fund our operations for at least the next 12 months.  Our cash cycle is such that we generally have visibility two to three quarters in advance for future orders that allows us to anticipate revenues over this period of time with some degree of confidence.  However, a sudden change in business volume, positive or negative, from any of our business or channel partners or in our direct business or any customer-driven events such as order or delivery deferral could significantly impact our expected revenues. The global economic uncertainty has reduced our confidence at predicting future revenues, and even with improving economic conditions, there is still uncertainty and risk in our forecasting.  This two to three quarter window of sales visibility does provide us with some opportunity to adjust expenditures or take other measures to reduce our cash consumption if we can see and anticipate a shortfall in revenue or give us time to identify additional sources of funding if we anticipate an increase in our working capital requirements due to increased revenues or changes in our revenue mix. A significant increase in sales, especially in our PowerHouse or our modular IT infrastructure solutions business, would likely increase our working capital requirements, due to the longer production time and cash cycle of sales of these products.

Item  3.	Quantitative and Qualitative Disclosures about Market Risk.	

We invest our cash in a variety of financial instruments, including bank time deposits, and taxable variable rate and fixed rate obligations of corporations, municipalities, and local, state and national government entities and agencies. These investments are denominated in U.S. dollars.

Our interest income is sensitive to changes in the general level of U.S. interest rates, particularly since the majority of our investments are in short-term instruments. We believe that our investment policy is conservative, both in terms of the average maturity of investments that we hold and in terms of the credit quality of the investments. Because of the nature of the majority of our investments, we do not believe a 1% decline in interest rates would have a material effect on interest income or on the fair value of our investments.

We continue to increase sales in foreign markets and do business in multiple foreign countries, executing more transactions that are denominated in other currencies. Those sales and expenses in currencies other than U.S. dollars can result in translation gains and losses which have not been significant to date. Currently, we do not engage in hedging activities for our international operations other than an increasing amount of sales and support expenses being incurred in foreign currencies as a natural hedge. However, recent volatility in currencies, particularly with the pound and Euro, is increasing the amount of potential translation gains and losses and we may engage in hedging activities in the future to mitigate the risks caused by such currency volatility.
 
Item  4.	Controls and Procedures (restated).	
 
Restatement

As discussed elsewhere in this Form 10-Q/A, including Note 2 to the unaudited condensed consolidated financial statements contained in Part I, Item 1 “Financial Statements (Unaudited) (Restated)”, we are restating and amending our previously issued unaudited condensed consolidated financial statements and related financial information for the three months ended March 31, 2013 previously included in our Quarterly Report on Form 10-Q for the period ended March 31, 2013, which was filed with the SEC on May 3, 2013.

Evaluation of Disclosure Controls and Procedures

In our Original Form 10-Q for the period ended March 31, 2013, filed on May 3, 2013, our management, including our then serving Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) promulgated under the Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by the Original Form 10-Q. Based on that evaluation, management initially concluded that our disclosure controls and procedures were effective in reaching a reasonable level of assurance that information required to be included in our reports filed or submitted under the Exchange Act as of such time was recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms and such information was accumulated and communicated as appropriate to allow timely decisions regarding required disclosures.
 
In connection with the restatement discussed above, our management, including our current Chief Executive Officer and our Chief Financial Officer, reevaluated the effectiveness of our disclosure controls and procedures as of March 31, 2013 pursuant to Rule 13a-15(b) under the Exchange Act. As a result of such reevaluation, management has determined that there was a material weakness in our system of internal control over financial reporting as of such date, which has caused us to amend our Original Form 10-Q.  As a result of such material weakness, management, including our current Chief Executive Officer and Chief Financial Officer, has revised its earlier assessment and has now concluded that our disclosure controls and procedures were not effective as of March 31, 2013.
 
Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act are properly recorded, processed, summarized and reported within the time periods required by the SEC rules and forms. Management necessarily applied its judgment in assessing the costs and benefits of such controls and procedures that, by their nature, can provide only reasonable assurance regarding management’s control objectives. Management does not expect that its disclosure controls and procedures will prevent all errors and fraud. A control system, irrespective of how well it is designed and operated, can only provide reasonable assurance, and cannot guarantee that it will succeed in its stated objectives.
 
Changes in Internal Control Over Financial Reporting
 
Other than as described below, there have been no changes in internal control over financial reporting that occurred during the quarter ended March 31, 2013 that have materially affected, or are reasonably likely to affect materially, our internal control over financial reporting.

A material weakness is a control deficiency (within the meaning of the Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 5) or combination of control deficiencies, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected.  Management has identified a material weakness resulting from control deficiencies related to our credit approval process whereby we did not confirm information from an employee of the Company in China regarding the facts surrounding Qiyuan, a distributor which we entered into a distribution agreement with.  In response to such material weakness, management is implementing additional credit approval process procedures including actions to further verify the financial condition and ownership structure of all new customers.

PART II – OTHER INFORMATION

Item  1.	Legal Proceedings.	

SEC Inquiry

By letter dated September 30, 2013, the SEC Division of Enforcement notified us that it is conducting an investigation regarding us, including matters relating to our public statements regarding Digital China Information Services Company Limited (“Digital China”) and our distribution relationships in China. We have been and intend to cooperate fully with the SEC.

Audit Committee Internal Investigation

The audit committee of our Board of Directors, with the assistance of independent counsel, is also conducting an investigation into the facts and circumstances surrounding our agreements and transactions with Qiyuan, including the statements made regarding Qiyuan’s affiliation with Digital China. The investigation is ongoing.

Stockholder Litigation

On September 10, 2013, a purported class action complaint was filed in the United States District Court for the Western District of Texas against the Company and certain of its current and former executives. The case is captioned  Don Lee v. Active Power, Inc., et. al.,  Civil Action No. 1:3-cv-00797. The complaint alleges that on April 30, 2013, the Company announced during a conference call that it had entered into a strategic distribution partnership with Digital China.  However, on September 5, 2013, after the close of trading, the Company disclosed that its partnership was with Qiyuan Network System Limited, which is neither an affiliate nor a subsidiary of Digital China.  The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder, and seeks unspecified damages on behalf of all stockholders.

On September 13 and October 14, 2013, two separate stockholders filed complaints in the District Court of Travis County, Texas purporting to bring derivative actions on behalf of the Company against certain current and former officers and directors of the Company.  The first derivative action is captioned  Okumura v. Almgren, et. al. , Cause No. D-1-GN-13-003230 and the second derivative action is captioned  David B. Shaev IRA v. Milner, et. al. , Cause No. D-1-GN-13-003557.  The allegations of each derivative complaint mirror those of the class action complaint, and they assert claims for breach of fiduciary duty, unjust enrichment, and/or abuse of control and seek damages on behalf of the Company.  Defendants have entered into an agreement with each of the plaintiffs to stay both of the derivative actions pending the outcome of the motion to dismiss in the securities class action.

The Company has directors’ and officers’ and corporate liability insurance to cover risks associated with the stockholder litigation and has notified its insurers of the complaints described above.  Due to the early stage of each litigation, however, it is not possible to estimate the amount or range of possible loss that might result from adverse judgments or settlements of the actions.

Item  1A.	Risk Factors.	

You should carefully consider the risks described below and in Item 1A of our 2012 Annual Report on Form 10-K before making a decision to invest in our common stock or in evaluating Active Power and our business. The risks and uncertainties described below and in our 2012 Annual Report on Form 10-K are not the only ones we face. Additional risks and uncertainties that we do not presently know, or that we currently view as immaterial, may also impair our business operations. This report is qualified in its entirety by these risk factors.

The actual occurrence of any of the risks described below and in our 2012 Annual Report on Form 10-K could materially harm our business, financial condition and results of operations. In that case, the trading price of our common stock could decline.

We have recognized additional risks that have not previously been mentioned in our 2012 Annual Report on Form 10-K as outlined below.

Index
Our material weakness or other control deficiencies could result in errors in our reported results and could have a material adverse effect on our operations, investor confidence in our business and the trading price of our stock.
 
A material weakness is a control deficiency or combination of control deficiencies, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected.  Our management has identified a material weakness resulting from control deficiencies related to our credit approval process whereby we did not confirm information from an employee of ours in China regarding the facts surrounding Qiyuan, a distributor which we entered into a distribution agreement with.  In response to such material weakness, management is implementing additional credit approval process procedures including actions to further verify the financial condition and ownership structure of all new customers.  The material weakness is ongoing and has not been remediated as of yet. Management’s evaluation of our disclosure controls and procedures as of March 31, 2013 concluded that, as a result of the material weakness, our disclosure controls and procedures were not effective as of March 31, 2013 to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act are properly recorded, processed, summarized and reported within the time periods required by SEC rules.  Any material weakness or unsuccessful remediation could adversely impact investor confidence in the accuracy and completeness of our financial statements. As a result, our ability to obtain any additional financing, if needed, could be materially and adversely affected, which in turn could materially and adversely affect our business, our financial condition and the market value of our stock. In addition, perceptions of us among customers, lenders, investors, securities analysts and others could also be adversely affected.  We can give no assurances that the measures we have taken to date, or any future measures we may take, will remediate the material weaknesses identified or that any additional material weaknesses will not arise in the future.

Our pending legal matters have increased our costs and could result in fines and penalties.

We are involved in ongoing legal matters as described in “Part II—Item 1—Legal Proceedings.” These matters may harm our business or liquidity in the future. We have incurred and expect to continue to incur substantial expenses for legal and accounting services related to such matters. These matters have also required significant time and attention from our management.  At this point, we are unable to predict the duration, scope or results of the SEC investigation.  In connection with our pending legal matters, including any further litigation that may be pursued, we may incur defense costs that may exceed our insurance coverage. We may also incur costs if the insurers of our directors and officers and our liability insurers deny coverage for the costs and expenses related to any litigation.   Our pending legal matters are in the early stages and we cannot predict their outcomes.  Adverse outcomes or other developments during the course of such matters may harm our business, financial condition, results of operations or liquidity as well as investors’ perception of our business.
