All forward-looking statements included in this document are based on information available to us on the date hereof. We assume no obligation to update any forward-looking statements.

The information contained in this Annual Report is as of December 31, 2013, unless expressly stated otherwise.

As used in this report, the term “we” or “Company” refers to BioLargo, Inc., a Delaware corporation, and its subsidiaries, BioLargo Life Technologies, Inc., a California corporation, Odor-No-More, Inc., a California corporation, BioLargo Water, Inc., a California corporation, and Clyra Medical Technologies, Inc., a California corporation. On January 10, 2014, we formed a Canadian subsidiary BioLargo Water, Inc.

Our Business

By leveraging our suite of patented and patent-pending intellectual property, which we refer to as the “BioLargo Technology”, our business strategy is to harness and deliver nature’s best disinfectant – iodine – in a safe, efficient, environmentally sensitive and cost-effective manner. The core of this innovative technology is the accurate and safe delivery of iodine in a wide range of forms, moieties and conditions. Iodine is an essential nutrient and all natural broad-spectrum disinfectant with no known microbial resistance. When used effectively, it can keep people and the world safer from disease and infection, and can be engaged as a powerful oxidant and catalyst to keep our water, earth, and air clean, safe, and healthy. Our goal is to target our capabilities to create and utilize iodine to improve the quality of life for people worldwide, to protect the environment, all while producing positive economic results for our customers, partners, and shareholders.

- 1 -

Our products offer a solution to an array of pervasive problems, including odor, moisture control, disinfection, wound healing and contaminated water. The iodine most of us are familiar with, sold in pharmacies and used by hospitals, has severe limitations – it is considered toxic, causes staining, and contains a limited dose of the active oxidizing ingredient. Our technology, on the other hand, directly addresses many of these shortcomings – we can deliver iodine’s oxidizing ingredient (“free iodine”) with precision, ranging from very small doses up to very large doses with more than 20 times the power of traditional iodine. We can deliver iodine so that it is both non-toxic and non-staining, thus extending its usefulness well beyond historical product applications. Consequently, we feel our best advantage is to leverage iodine’s breadth to develop uses and products that offer a competitive edge against other technologies. These uses can secure BioLargo its highest value proposition, resulting in sales and licensing opportunities.

The centerpieces of our technology are embodied by our patented and proprietary CupriDyne^® and its methods of delivery, the Isan™ system, and our BioLargo® AOS Filter (“Advanced Oxidation System”). These technologies offer a nearly seamless range of capabilities for the generation, delivery and control of iodine and implementation of iodine in most of its moieties.

General Benefits of Our Technology

Generally, our technology offers the following beneficial features, among others:

● Cost Competitiveness — The simplicity and efficacy of our technology can offer lower total costs for both manufacturer and consumer.

● Broad Spectrum Disinfection — Our technology offers selective and/or an additive germ killing strategy. It permits flashing or metered dosing of targets with iodine, as required for each application, and functions at a wide range of pH, further extending its viability.

● Deodorization — Our technology can deliver iodine in an oxidative form that rapidly, yet safely, destroys odor-causing compounds, eliminating odor.

● Non-Staining— Unlike the iodine solutions currently used in medicine and sold in stores, many of our iodine formulations do not stain or chemically discolor surfaces on contact.

● Increased Holding Power— Our technology can significantly increase the holding power of absorbent materials, depending on product configuration.

● Disposal of Contaminations — In certain applications, our technology can render contaminated or infectious material safe to handle.

● Safety— Many applications of our technology utilize or create compounds which are generally recognized as safe (“GRAS”) as food ingredients by the U.S. Food and Drug Administration (“FDA”).

● Flexibility— Our technology is easily combined with a broad array of materials and complimentary chemicals to create or improve formulated products and delivery systems.

- 2 -

● Lower Corrosion— Our technology is significantly less corrosive than other chemicals (such as chlorine), which may help extend the useful life of certain industrial equipment.

Focus of Commercial Applications

The list of potential uses and commercial opportunities can appear endless. We have chosen to focus on applications we believe have some combination of the following attributes:

1. a compelling commercial advantage;

2. our products out-perform competing products;

3. market segments in which we have the talent and resources or opportunity to succeed in executing our business plans; and

4. uses where we can identify a compelling cost savings or value offering to increase market share.

Although our technology has potential commercial applications within many industries, we are focusing our efforts in three areas:

1. Water treatment;

2. The companion animal industry, as a segment of the commercial, household and personal care products (“CHAPP”); and

3. Advanced wound care.

Within these broad categories, we also narrow our product focus to exploit opportunities that we believe are of high-value to potential customers and that present commercially significant opportunities.

Water Treatment

We have developed and are further refining a technology for water treatment called the BioLargo AOS Filter, an advanced oxidation system, which we believe represents a technical breakthrough in water purification. We expect our patent-protected technology will impact a number of major water industry segments. Our invention has proven effective in dismantling and removing soluble and difficult to manage contaminants as well as, in particular, treating tailings ponds water in bench scale trials and is now entering into pilot phase at the University of Alberta. Our technology also promises to compete as a low-cost solution in many other markets, including traditional oil and gas (e.g., fracking), and industrial water.

Our California subsidiary BioLargo Water, Inc. holds the exclusive worldwide rights to the BioLargo AOS Filter. The intellectual property associated with the BioLargo AOS Filter includes issued patents, recently allowed patents, patent applications in the United States, Canada and EU, know-how, and trade secrets. Revenue opportunities present themselves in many forms: licensing, sale, manufacturing, servicing, joint venture, leasing, tolling, etc. We are proceeding in a pilot project to treat processed water from the Athabasca Oil Sands.

- 3 -

Athabasca Oil Sands

The Canadian Oil Sands are believed to be the second largest deposit of oil in the world. Extracting oil from the Oil Sands creates high volumes of contaminated water (between 2 and 4.5 barrels of water to produce one barrel of synthetic crude oil), currently discharged in “tailings” ponds, sometimes for years, to separate the solids from the liquids for eventual recycling or safe discharge into the environment. With Canada hoping to increase its oil production from 1.9 million to over 6 million barrels of oil a day over the next 20 years, the released water from oil sands operations is estimated to reach one billion cubic meters in the Athabasca oils sands region by 2025. An innovative solution that can reduce the water treatment time, and thus the overall footprint and environmental impact of the tailings ponds, is required for Canada to meet its production goals. It is widely believed that the future of oil sands exploration, its social and economic contribution as the second largest oil reserve in the world, and its contribution to the public good of both Canada and the United States, hinges on industry’s ability to manage the wastewater in tailings ponds. The Canadian government has set aside over $3.5B to the reclamation of the natural landscape including the contaminated water issues.

The proof-of-claim work at the University of Alberta verifies that our AOS technology can be highly effective in addressing this issue. We have been able to show performance results (dismantling contaminants from a flow of water) at an efficiency level that has never before been seen commercially. As a result of the validation and support expressed for the project by the University of Alberta, researchers and funding agencies, a new $5+ million pilot study is scheduled to begin in 2014. The University is tasked to engineer the solution to work on the large scale required for these tailing ponds in preparation for commercialization. The lead researcher from the University, Mohamed Gamal El-Din, Ph.D., P.E., will lead the pilot study. We are working with the Dr. Gamal El-Din on funding from government and private sources. We expect to execute a formal research contract for the pilot project in the near future.

Other Oil and Gas Industry Applications

The environmental problems caused by oil and gas exploration are well documented. We believe our technology can play an important role in any of the areas within this industry that must contend with managing contaminated water, bacteria, volatile organic compounds, or other pollutants. For example, “hydraulic fracturing,” or “fracking” is the process of injecting liquids into geologic formations to release natural gas and oil. Fracking creates large quantities of contaminated water that must be treated before reuse or release into the environment. We believe our AOS system offers important and material advantages relative to current processes that address water issues related to the extraction of oil and gas commodities. As the industry copes with increasing regulatory and political pressures to mitigate all forms that directly pollute our country’s aquifers with toxic materials, and ensure environmentally sound operating procedures, we are positioned to become the industry standard for the treatment of flow back water in the future with an emphasis on providing on-site treatment for water reuse.

To facilitate an understanding and positioning in this segment, in 2010, we added to our team the former chief technology officer of oil industry giant Halliburton, Dr. Vikram Rao. Having spent more than 30 years at Halliburton, Dr. Rao is the author of more than 40 publications, has been awarded 24 patents, serves as the Executive Director of the Research Triangle Energy Consortium, and brings his experience and industry connections to BioLargo.

Industrial Water Treatment

Industrial water treatment is very broad in scope, yet our technology provides some unique, continuous handling and cost effective solutions. An immediate focus is process systems, which require continuous monitoring and adjustment such as heat exchange water. Standard processing commonly uses filters to remove particulate matter and other contaminants as well as chemicals to reduce scale and prevent bio-growth. BioLargo can trim chemical consumption, lengthen filter life, slash common corrosion issues and reduce the incidence of dangerous byproducts like trihalomethanes (THM) that are common with chemicals such as chlorine.

- 4 -

In February 2011, we added to our team former Pepsi-Cola International VP of Technical Services, and recognized industry water treatment expert, with life time achievement honors in both the AWWA (American Water Works Association) and the International Society of Beverage Technologists, Harry DeLonge. Having spent more than 40 years at Pepsi-Cola International, Mr. DeLonge is assisting with efforts to commercialize our technology in this segment. In addition, we believe that we have a cost effective solution for managing dangerous and/or odorless compounds common with this industry. With Mr. DeLonge’s assistance, we are developing new patents and other intellectual property, advancing proof of claim, and seeking pilot projects and customers and/or licensing partners. These efforts are continuing in 2014.

Commercial, Household and Personal Care Products

CHAPP includes broad product categories and many opportunities for the application of our technology. It is defined by the ability to utilize similar, if not identical, consumption products in multiple market segments. Detergents, single use absorbents, wipes, products that provide odor or disinfection control, and stain removal all fall within this category. Packaging ranges from consumer sizes of a few ounces to bulk packaging for commercial or industrial use. We are currently marketing products in this category under four brands – Odor-No-More, Nature’s Best Solution, Deodorall, and NBS - direct to consumers, through retail stores, and most recently, to the U.S. Government. 

We engaged a leading third party testing company to compare our pet products’ performance against leading brands and the testing verified that we outperform the leading brands in odor control in side-by-side consumer testing. Cat Fancy Magazine named our "Litter Deodorizing Concentrate" one of 18 "Best Products of the Year" for 2013, and it won an "Editor's Choice Award" from Pet Product News International.   

In April 2013 we added our pet line of products under our “Deodorall” brand, with the intent to distribute our pet products under the Deodorall brand through mass-merchant (non-pet) retailers. We have retained sales representative agencies that specialize in various aspects of the retail market, including pet and mass merchant, to have our products placed at national retailers. We have test marketed a series of label designs and package refinements, and are targeting national and regional retailers to carry our products and/or develop a private label product using our patented formulas.

Were any national or regional chain to carry our products, we anticipate a need for increased investment capital to conduct an appropriate marketing campaign, and to reinvest most of the margin available from early sales into marketing and merchandising, to support the sell through of the products. While we have had discussions with a number of capital sources and believe that we would be able to successfully secure the needed capital to support such a campaign, until such time as the specifics requirements are well defined and related negotiations are complete, we can make no assurances that we will be successful in such financing activities.

In October 2013 we introduced a new line of odor and moisture control products to the US Government in a pouch and canister design that can be used to solidify liquids or absorb blood and other bodily fluids. We initially plan to target government medical providers, and plan to expand into general industrial applications and first responders markets. We are currently selling into this channel.

 A third party distributor markets “Deodorall Sport” to the sporting goods apparel and equipment industry with an emphasis in the ice hockey industry. We are actively developing new complimentary products and refining our existing products to support this selling channel. Our products are being introduced and sold into retail stores in time for the fall and winter sports seasons.

- 5 -

Our sales in the CHAPP product category to-date are nominal. Product development, sales, and marketing require significant financial resources that we currently do not have. As such, our progress in this area has been slower than we had hoped. As our financial resources permit, we will continue to evaluate and test new products, marketing programs and selling opportunities, as well as strategic alliances to expand and refine our messaging and generate sales. We are actively marketing the technology for licensure to established companies in this industry segment.

Advanced Wound Care – Clyra Medical Technologies Subsidiary

In 2012 we formed a subsidiary Clyra Medical Technologies, Inc. (“Clyra”) to commercialize our technology in the medical products industry, with an initial focus on advanced wound care. Our advanced wound care products combine broad-spectrum antimicrobial capabilities with iodine’s natural and well-understood metabolic pathway to promote healing. We believe these benefits, along with reduced product costs as compared with other antimicrobials, give our products a competitive advantage in the marketplace.

In 2012 Clyra entered into a strategic supply agreement with Formulated Solutions, a state-of-the-art FDA registered drug and device manufacturing company in Florida, to conclude development and testing, and apply for FDA 510(k), approval for its first two products to be sold into the advanced wound care industry. While no assurances can be made about the ultimate success of such applications, given the forward looking nature of such events, Clyra has retained and engaged a team of experts in the area to guide it through the process. The product development process has been more time consuming than originally anticipated, and our limited financial resources have impacted our ability to complete the process. Given the timing of the FDA process, and the requirement for approval before product can be sold, we do not anticipate product sales until 2015. In the interim, we will continue to seek licensing partners, secure additional and dedicated capital resources for Clyra, and refine our product roll out, marketing, and distribution plans.

License Agreement

On December 17, 2012, we entered into a license agreement in which we granted our subsidiary Clyra the exclusive world-wide right to make, have made, use, sell, offer for sale, and import products for use within the field of human wound care (as defined in the agreement), expandable to include other medical products. Once Clyra meets certain funding goals, the license agreement requires it pay to us a $50,000 per month license fee, as well as a six percent royalty on product sales. Clyra has the rights to sublicense the technology, with our approval, and in such instances must split equally with us any sublicense fees.

On December 17, 2012 we also granted 1,500 shares of Clyra common stock (of an aggregate total 9,000 issued and outstanding) to members of its management team. Additionally, Clyra sold 240 shares of its common stock in a private securities offering. On February 1, 2014, Clyra began a second private offering of its securities to raise capital for its research and development activities.

The Isan System

The Isan system is a proprietary automated water disinfection system that substantially reduces the incidence of fungal growth, spoilage, organisms and pathogens in water and on food. The system is able to operate at high flow rates and performs key steps in the process:

1. Accurately measures prevailing levels of iodine in a target water stream.

- 6 -

2. A control unit measures, monitors, and systematically controls and documents the process.

3. Iodine canisters, controlled by the Isan system, deliver iodine in a non-toxic, non-corrosive, non-staining manner at a prescribed flow rate.

4. Resin canisters collect by-products after disinfection is complete.

Developed in Australia, the Isan system was initially registered with the APVMA (Australian Pesticides and Veterinary Medicines Authority) and FSANZ (Food Standards Australia and New Zealand) in Australia and New Zealand.

In 2012, we executed a joint venture agreement with Peter Holdings Ltd., the principal funding source of the development of the Isan system, whereby we jointly purchased the intellectual property associated with the Isan system. In February 2014 we received a deposit of $100,000 towards a worldwide, exclusive license of the Isan System. We have agreed to provide all technical and engineering specifications, three assembled and operating Isan units, all patent and other intellectual property, and other items related to the Isan operations in Australia and New Zealand. In addition to a $100,000 advanced royalty payment, the licensee has agreed to pay 10% of sales as a royalty, $50,000 minimum per quarter beginning in year 3, a patent maintenance fee of $25,000 annually, paid quarterly in arrears. Final documents are being drafted.

Manufacturing

Other than limited or sample runs, we do not presently intend to manufacture products we sell, but rather contract with third parties to do so. We currently work with manufacturers on a contract-for-hire basis, or on a project-by-project basis, with the potential for these manufacturers to create a product supplier relationship for potential licensees of products incorporating our technology. We are currently negotiating with third party material components providers and manufacturers, and equipment manufacturers, for production of our new products.

We also use third party manufacturers to produce chemicals such as tablets and powders, and multiple suppliers of such absorbent materials and chemical reagents. We do not have exclusive arrangements or written agreements with any such manufacturers that we have used to date. We have several choices for manufacturers of chemicals and are not dependent upon any single manufacturer or source of materials. Most of the chemicals we use in the production of our CupriDyne® based products, such as potassium iodide, are not typically scarce or subject to price volatility, but there is no assurance that will not change in the future. Some of our products incorporate “super absorbent polymers,” which are subject to price volatility and scarcity.

Competition

We believe that our products contain unique characteristics that differentiate them from competing products. But our products face competition from products with similar prices and similar claims. Large well-capitalized companies, such as Johnson & Johnson, BASF Corporation, Dow Chemical Co., E.I. DuPont De Nemours & Co., Chemical and Mining Company of Chile, Inc., Proctor and Gamble Co., Diversey, Inc., EcoLab, Inc., Steris Corp., Chlorox, Reckitt Benckiser GE Water, Trojan UV and Siemens AG, and others, dominate each of their respective markets for disinfecting or sanitizing products. In the medical markets, we compete with companies like Smith & Nephew, 3M, ConvaTec and Derma Sciences. In pet markets, we compete with established companies such as Arm & Hammer and United Pet Group (owner of Nature’s Miracle branded products). Each of these named companies and many other competitors are significantly more capitalized than we are and have many more years of experience in producing and distributing products.

- 7 -

Our technology and products incorporating our technology would compete with many other applications currently on the market. In addition, we are aware of other companies engaged in research and development of other novel approaches to applications in some or all of the markets identified by us as potential fields of application for our products and the Isan system. Many of our present and potential competitors have substantially greater financial and other resources and larger research and development staffs than we have. Many of these companies also have extensive experience in testing and applying for regulatory approvals. In addition, colleges, universities, government agencies, and public and private research organizations conduct research and are becoming more active in seeking patent protection and licensing arrangements to collect royalties for the use of technology that they have developed, some of which may be directly competitive with our applications.

Intellectual Property and Research and Development

We regard our intellectual property as critical to our ultimate success. Our goal is to obtain, maintain and enforce patent protection for our products and technologies in geographic areas of commercial interest, and to protect our trade secrets and proprietary information through laws and contractual arrangements.

Our Chief Science Officer, Mr. Kenneth R. Code, has been involved in the research and development of the BioLargo technology since 1997. He has participated in the Canadian Federal Scientific Research and Experimental Development program and he was instrumental in the discovery, preparation and filing of the first BioLargo technology patents. He has worked with manufacturers, distributors and suppliers in a wide variety of industries to gain a full appreciation of the potential applications and the methodologies applicable to our BioLargo technology for their manufacture and performance. He continues to research methods and applications to continue to expand the potential uses of our BioLargo technology as well as work to uncover new discoveries that may provide addition commercial applications to help solve real world problems in the field of disinfection.

In 2012 and 2013, we continued improving our technology and creating new uses of our technology through further research and development efforts. During that time, we filed two U.S. patent applications, each comprised of multiple individual claims, and received notice of allowance or were granted five patents by the USPTO. Our technology also includes know-how and trade secrets, which, together with our intellectual property, contribute to our expertise in product design, manufacturing, product claims, safety features and competitive positioning of products that feature our BioLargo technology.

During 2014 we plan to continue to advance our proof of claims, inventions and patent filings.

We spent $383,549 in 2012 and $742,247 in 2013 on research and development activities. Our research and development expenditures over the next 12 months could vary significantly and will depend upon our access to capital. Although we are actively pursuing such financing, no such commitment is yet in place. We would invest any such funds primarily on continued testing of our BioLargo technology in certain applications and the development of additional production methods for use of our BioLargo technology in certain applications.

An additional divisional application based on this application was filed in 2013.

● US Patent Application 13/308,105 (filed November 30, 2011) relating to our “AOS Filter”, titled “Antimicrobial and Antiodor Solutions and Delivery Systems” relating to our liquid antimicrobial solutions, including our gels, sprays and liquids imbedded into wipes and other substrates. We received Notice of Allowance from the USPTO in December 2013, and are awaiting the issuance of this patent.

In addition to these applications, we have filed patent applications in multiple foreign countries, including the European Union, pursuant to the PCT, and other provisional applications. Subject to adequate financing, we intend to continue to expand and enhance our suite of intellectual property through ongoing focus on product development, new intellectual property development and patent applications, and further third-party testing and validations for specific areas of focus for commercial exploitation. We currently anticipate that additional patent applications will be filed during the next 12 months with the USPTO and the PCT, although we are uncertain of the cost of such patent filings, which will depend upon the number of such applications prepared and filed. The expense associated with seeking patent rights in multiple foreign countries is expensive, and will require substantial ongoing capital resources. However we cannot give any assurance that adequate capital will be available. Without adequate capital resources, we will be forced to abandon patent applications and irrevocably lose rights to our technologies.

ITEM 1A. RISK FACTORS

The Company faces a number of significant risks associated with its current plan of operations. These include the following:

The effects of the recent global economic crisis has had an impact our business, operating results, and financial condition, and the rate of recovery is uncertain.

The recent global economic crisis has caused disruptions and extreme volatility in global financial markets and increased rates of default and bankruptcy, and has impacted levels of consumer spending. It has tightened the supply of investment capital. These macroeconomic developments and the unpredictable rate of recovery could continue to negatively affect our business, operating results, and financial condition in a number of ways.

Our limited operating history makes evaluation of our business difficult.

We have limited historical financial data upon which to base planned operating expenses or forecast accurately our future operating results. Further, our limited operating history will make it difficult for investors and securities analysts to evaluate our business and prospects. Our failure to address these risks and difficulties successfully could seriously harm us.

We have never generated any significant revenues, have a history of losses, and cannot assure you that we will ever become or remain profitable.

We have not yet generated any significant revenue from operations and, accordingly, we have incurred net losses every year since our inception. To date, we have dedicated most of our financial resources to research and development, general and administrative expenses and initial sales and marketing activities. We have funded the majority of our activities through sales of our debt or securities. We anticipate net losses and negative cash flow to continue for the foreseeable future until such time as licensing or operating revenue is generated in sufficient amounts to offset operating losses. Our ability to achieve profitability is dependent upon our continuing research and development, product development, and sales and marketing efforts, and our ability to successfully license our technology. There can be no assurance that our revenues will be sufficient for us to become profitable or thereafter maintain profitability. We may also face unforeseen problems, difficulties, expenses or delays in implementing our business plan.

Our cash requirements are significant. The failure to raise additional capital will have a significant adverse effect on our financial condition and its operations.

Our cash requirements and expenses will continue to be significant. Our net cash used in continuing operations for the years ended December 31, 2013 and 2012 was $1,212,252 and $2,032,804, respectively. These negative cash flows are primarily related to operating losses and, to a lesser extent, fluctuations in working capital items. We continue to use cash in 2014 as it becomes available and we anticipate that we will require significant additional financing for working capital requirements for the foreseeable future to continue the development, marketing and licensure of our technology and products based on our technology. Although we have been successful in raising funds in the past, there can be no assurance that we will be able to successfully raise funds in the future, especially in light of current adverse conditions in the capital markets and the weak economy generally. The failure to raise additional capital will have a significant adverse effect on our financial condition, our operations, and our ability to market and sell our products. Our ability to continue as a going concern is dependent on our ability to raise capital.

- 12 -

From time to time, we issue stock, instead of cash, to pay some of our operating expenses. These issuances are dilutive to our existing stockholders.

We are party to agreements that provide for the payment of, or permit us to pay at our option, securities in consideration for services provided to us. All such issuances are dilutive to our stockholders because they increase the total number of shares of our common stock issued and outstanding, even though such arrangements assist us with managing our cash flow at a time of increasing operating expenses coupled with decreased and further decreasing liquidity.

Our stockholders face further potential dilution in any new financing.

Any additional equity that we raise would dilute the interest of the current stockholders and any persons who may become stockholders before such financing. Given the low price of our common stock, such dilution in any financing of a significant amount could be substantial.

Our stockholders face further potential adverse effects from the terms of any preferred stock which may be issued in the future.

In order to raise capital to meet expenses or to acquire a business, our Board of Directors may issue additional stock, including preferred stock. Any preferred stock which we may issue may have voting rights, liquidation preferences, redemption rights and other rights, preferences and privileges. The rights of the holders of our common stock will be subject to, and in many respect subordinate to, the rights of the holders of any such preferred stock. Furthermore, such preferred stock may have other rights, including economic rights, senior to our common stock that could have a material adverse effect on the value of our common stock. Preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, can also have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock, thereby delaying, deferring or preventing a change in control of the Company.

There are several specific business opportunities we are considering in further development of our business. None of these opportunities is yet the subject of a definitive agreement and most or all of these opportunities will require additional funding obligations on our part, for which funding is not currently in place.

In furtherance of our business plan, we are presently considering a number of opportunities to promote our business, to further develop and broaden, and to license, our technology with third parties. While discussions are underway with respect to such opportunities, there are no definitive agreements in place with respect to any of such opportunities at this time. There can be no assurance that any such opportunities being discussed will result in definitive agreements or, if definitive agreements are entered into, that they will be on terms that are favorable to us.

Moreover, should any of these opportunities result in definitive agreements being entered into, we may be required to expend additional monies above and beyond our current operating budget to promote such endeavors. No such financing is in place at this time for such endeavors and we cannot assure you that any such financing will be available, or if it is available whether it will be on terms that are favorable to the company.

- 13 -

The cost of maintaining our public company reporting obligations is high.

We are obligated to maintain our periodic public filings and public reporting requirements, on a timely basis, under the Rules and Regulations of the SEC. In order to meet these obligations, we will need to continue to raise capital. If adequate funds are not available, we will be unable to comply with those requirements and could cease to be qualified to have our stock traded in the public market. As a public company, we incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002, as well as related rules adopted by the SEC, has imposed substantial requirements on public companies, including certain corporate governance practices and requirements relating to internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act.

We expect to incur future losses and may not be able to achieve profitability.

Although we are generating limited revenue from the sale of our products, and we expect to generate revenue from new products we are introducing, and eventually from other license or supply agreements, we anticipate net losses and negative cash flow to continue for the foreseeable future until such time as our products are expanded in the marketplace and they gain broader acceptance by resellers and customers. Our current level of sales is not sufficient to support the financial needs of our business. We cannot predict when sales volumes will be sufficiently large to cover our operating expenses. We intend to expand our marketing efforts of our products as financial resources are available, and we intend to continue to expand our research and development efforts. Consequently, we will need to generate significant additional revenue or seek additional funding to fund our operations. This has put a proportionate corresponding demand on capital. Our ability to achieve profitability is dependent upon our efforts to deliver a viable product and our ability to successfully bring it to market, which we are currently pursuing. Although our management is optimistic that we will succeed in licensing our technology, we cannot be certain as to timing or whether we will generate sufficient revenue to be able to operate profitably. If we cannot achieve or sustain profitability, we may not be able to fund our expected cash needs or continue our operations. If we are not able to devote adequate resources to promote commercialization of our technology, our business plans will suffer and may fail.

Because we have limited resources to devote to sales, marketing and licensing efforts with respect to our technology, any delay in such efforts may jeopardize future research and development of technologies, and commercialization of our technology. Although our management believes that it can finance commercialization efforts through sales of our securities and possibly other capital sources, if we do not successfully bring our technology to market, our ability to generate revenues will be adversely affected.

If we are not able to manage our anticipated growth effectively, we may not become profitable.

We anticipate that expansion will continue to be required to address potential market opportunities for our technology and our products. Our existing infrastructure is limited, is not scalable, and will not support future growth, if any. There can be no assurance that we will have the financial resources to create new infrastructure, or that any such infrastructure will be sufficiently scalable to manage future growth, if any. There also can be no assurance that if we invest in additional infrastructure, we will be effective in expanding our operations or that our systems, procedures or controls will be adequate to support such expansion. In addition, we will need to provide additional sales and support services to our partners if we achieve our anticipated growth with respect to the sale of our technology for various applications. Failure to properly manage an increase in customer demands could result in a material adverse effect on customer satisfaction, our ability to meet our contractual obligations, and on our operating results.

- 14 -

Some of the products incorporating our technology will require regulatory approval.

The products in which our technology may be incorporated have both regulated and non-regulated applications. The regulatory approvals for certain applications may be difficult, impossible, time consuming and or expensive to obtain. While our management believes such approvals can be obtained for the applications contemplated, until those approvals from the FDA or the EPA or other regulatory bodies, if required, at the federal and state levels, as may be required are obtained, then we may not be able to generate commercial revenues. Certain specific regulated applications and its use therein require highly technical analysis, additional third party validation and will require regulatory approvals from organizations like the FDA. Certain applications may also be subject to additional state and local agency regulations, increasing the cost and time associated with commercial strategies. Additionally, most products incorporating our technology that may be sold in the European Union (“EU”) will require EU and possibly also individual country regulatory approval. All such approvals, including additional testing, are time-consuming, expensive and do not have assured outcomes of ultimate regulatory approval.

We need to outsource and rely on third parties for the manufacture of the chemicals, material components or delivery apparatus used in our technology and part of our future success will be dependent on the timeliness and effectiveness of the efforts of these third parties.

We do not have the required financial and human resources or capability to manufacture the chemicals that comprise our technology. Our business model calls for the outsourcing of the manufacture of these chemicals in order to reduce our capital and infrastructure costs as a means of potentially improving our financial position and the profitability of our business. Accordingly, we must enter into agreements with other companies that can assist us and provide certain capabilities, including sourcing and manufacturing, which we do not possess. We may not be successful in entering into such alliances on favorable terms or at all. Even if we do succeed in securing such agreements, we may not be able to maintain them. Furthermore, any delay in entering into agreements could delay the development and commercialization of our technology or reduce its competitiveness even if they reach the market. Any such delay related to such future agreements could adversely affect our business.

If any party to which we have outsourced certain functions fails to perform its obligations under agreements with us, the commercialization of our technology could be delayed or curtailed.

To the extent that we rely on other companies to manufacture the chemicals used in our technology, or sell or market products incorporating our technology, we will be dependent on the timeliness and effectiveness of their efforts. If any of these parties does not perform its obligations in a timely and effective manner, the commercialization of our technology could be delayed or curtailed because we may not have sufficient financial resources or capabilities to continue such efforts on our own.

We rely on a small number of key supply ingredients in order to manufacture our products

All of the supply ingredients used to manufacture our products are readily available from multiple suppliers. However, commodity prices for these ingredients can vary significantly and the margins that we are able to generate could decline if prices rise. If our manufacturing costs rise significantly, we may be forced to raise the prices for our products, which may reduce their acceptance in the marketplace.

If our technology or products incorporating our technology do not gain market acceptance, it is unlikely that we will become profitable.

The potential markets for products into which our technology can be incorporated are rapidly evolving, and we have many successful competitors. At this time, our technology is unproven in its commercial use, and the use of our technology by others is nominal. The commercial success of products incorporating our technology will depend upon the adoption of our technology by commercial and consumer end users in various fields.

- 15 -

Market acceptance may depend on many factors, including:

• the willingness and ability of consumers and industry partners to adopt new technologies;

• our ability to convince potential industry partners and consumers that our BioLargo technology is an attractive alternative to other technologies for disinfection, sanitization, remediation, reduction of disease transfer and as a protective and safety device against biohazardous materials;

• our ability to obtain the chemicals from third parties that are used in our BioLargo technology, in sufficient quantities with acceptable quality and at an acceptable cost; and

• our ability to license our BioLargo technology in a commercially effective manner.

If products incorporating our technology do not achieve a significant level of market acceptance, demand for our technology itself may not develop as expected and, in such event, it is unlikely that we will become profitable.

Any revenues that we may earn in the future are unpredictable, and our operating results are likely to fluctuate from quarter to quarter.

We believe that our future operating results will fluctuate due to a variety of factors, including:

• delays in product development by us or third parties;

• market acceptance of products incorporating our BioLargo technology;

• changes in the demand for, and pricing, of products incorporating our BioLargo technology;

• competition and pricing pressure from competitive products;

• manufacturing delays; and

• expenses related to, and the results of, proceedings relating to our intellectual property.

We expect our operating expenses will continue to fluctuate significantly in 2014 and beyond, as we continue our research and development, and increase our marketing and licensing activities. Although we expect to generate revenues from licensing our technology in the future, revenues may decline or not grow as anticipated and our operating results could be substantially harmed for a particular fiscal period. Moreover, our operating results in some quarters may not meet the expectations of stock market analysts and investors. In that case, our stock price most likely would decline.

We have no product distribution experience and we expect to rely on third parties who may not successfully sell our products.

We have no product distribution experience and currently rely and plan to rely primarily on product distribution arrangements with third parties. We also plan to license our technology to certain third parties for commercialization of certain applications. We expect to enter into additional distribution agreements and licensing agreements in the future, and we may not be able to enter into these additional agreements on terms that are favorable to us, if at all. In addition, we may have limited or no control over the distribution activities of these third parties. These third parties could sell competing products and may devote insufficient sales efforts to our products. As a result, our future revenues from sales of our products, if any, will depend on the success of the efforts of these third parties.

- 16 -

We may not be able to attract or retain qualified senior personnel.

We believe we are currently able to manage our current business with our existing management team. However, as we expand the scope of our operations, we will need to obtain the full-time services of additional senior management and other personnel. Competition for highly-skilled personnel is intense, and there can be no assurance that we will be able to attract or retain qualified senior personnel. Our failure to do so could have an adverse effect on our ability to implement our business plan. As we add full-time senior personnel, our overhead expenses for salaries and related items will increase from current levels and, depending upon the number of personnel we hire and their compensation packages, these increases could be substantial.

If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve profitability.

Our future success is substantially dependent on the efforts of our senior management, particularly Dennis P. Calvert, our president and chief executive officer, and Kenneth Reay Code, our chief science officer. The loss of the services of either of these officers or other members of our senior management may significantly delay or prevent the achievement of product development and other business objectives. Because of the scientific nature of our business, we depend substantially on our ability to attract and retain qualified marketing, scientific and technical personnel. There is intense competition among specialized and technologically-oriented companies for qualified personnel in the areas of our activities. If we lose the services of, or do not successfully recruit key marketing, scientific and technical personnel, the growth of our business could be substantially impaired. At present, we do not maintain key man insurance for any of our senior management, although management is evaluating the potential of securing this type of insurance in the future as may be available.

Nondisclosure agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information.

In order to protect our proprietary technology and processes, we rely in part on nondisclosure agreements with our employees, potential licensing partners, potential manufacturing partners, testing facilities, universities, consultants, agents and other organizations to which we disclose our proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position. Since we rely on trade secrets and nondisclosure agreements, in addition to patents, to protect some of our intellectual property, there is a risk that third parties may obtain and improperly utilize our proprietary information to our competitive disadvantage. We may not be able to detect unauthorized use or take appropriate and timely steps to enforce our intellectual property rights.

We may become subject to product liability claims.

As a business which manufactures and markets products for use by consumers and institutions, we may become liable for any damage caused by our products, whether used in the manner intended or not. Any such claim of liability, whether meritorious or not, could be time-consuming and/or result in costly litigation. Although we maintain general liability insurance, our insurance may not cover potential claims of the types described above and may not be adequate to indemnify for all liabilities that may be imposed. Any imposition of liability that is not covered by insurance or is in excess of insurance coverage could harm our business and operating results, and you may lose some or all of any investment you have made, or may make, in our company.

- 17 -

Litigation or the actions of regulatory authorities may harm our business or otherwise distract our management.

Substantial, complex or extended litigation could cause us to incur major expenditures and distract our management. For example, lawsuits by employees, former employees, shareholders, partners, customers, or others, or actions taken by regulatory authorities, could be very costly and substantially disrupt our business.  Such lawsuits or actions could from time to time be filed against the Company and/or or our executive officers and directors.  Such lawsuits and actions are not uncommon, and we cannot assure you that we will always be able to resolve such disputes or actions on terms favorable to the Company.

If we suffer negative publicity concerning the safety or efficacy of our products, our sales may be harmed

If concerns should arise about the safety or efficacy of any of our products that are marketed, regardless of whether or not such concerns have a basis in generally accepted science or peer-reviewed scientific research, such concerns could adversely affect the market for those products. Similarly, negative publicity could result in an increased number of product liability claims, whether or not those claims are supported by applicable law.

The licensing of our technology or the manufacture, use or sale of products incorporating our technology may infringe on the patent rights of others, and we may be forced to litigate if an intellectual property dispute arises.

If we infringe or are alleged to have infringed another party’s patent rights, we may be required to seek a license, defend an infringement action or challenge the validity of the patents in court. Patent litigation is costly and time consuming. We may not have sufficient resources to bring these actions to a successful conclusion. In addition, if we do not obtain a license, do not successfully defend an infringement action or are unable to have infringed patents declared invalid, we may:

      •           incur substantial monetary damages;

      •           encounter significant delays in marketing our current and proposed product candidates;

      •           be unable to conduct or participate in the manufacture, use or sale of product candidates or methods of treatment requiring licenses;

      •           lose patent protection for our inventions and products; or

      •           find our patents are unenforceable, invalid, or have a reduced scope of protection.

Parties making such claims may be able to obtain injunctive relief that could effectively block the company’s ability to further develop or commercialize our current and proposed product candidates in the United States and abroad and could result in the award of substantial damages. Defense of any lawsuit or failure to obtain any such license could substantially harm the company. Litigation, regardless of outcome, could result in substantial cost to, and a diversion of efforts by, the Company.

Our patents are expensive to maintain, our patent applications are expensive to prosecute, and thus we are unable to file for patent protection in many countries.

Our ability to compete effectively will depend in part on our ability to develop and maintain proprietary aspects of our technology and either to operate without infringing the proprietary rights of others or to obtain rights to technology owned by third parties. Pending patent applications relating to our technology may not result in the issuance of any patents or any issued patents that will offer protection against competitors with similar technology. We must employ patent attorneys to prosecute our patent applications both in the United States and internationally. International patent protection requires the retention of patent counsel in multiple foreign countries and the payment of patent application fees in multiple foreign countries on or before filing deadlines set forth by theInternational Patent Cooperation Treaty (“PCT”). We therefore choose to file patent applications only in foreign countries where we believe the commercial opportunities require it, considering our available finances and the needs for our technology. This has resulted, and will continue to result, in the irrevocable loss of patent rights in all but a few foreign jurisdictions.

- 18 -

Patents we receive may be challenged, invalidated or circumvented in the future or the rights created by those patents may not provide a competitive advantage. We also rely on trade secrets, technical know-how and continuing invention to develop and maintain our competitive position. Others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets.

We are subject to risks related to future business outside of North America.

Over time, we may develop business relationships outside of North America, and as those efforts are pursued, we will face risks related to those relationships such as:

• foreign currency fluctuations;

• unstable political, economic, financial and market conditions;

• import and export license requirements;

• trade restrictions;

• increases in tariffs and taxes;

• high levels of inflation;

• restrictions on repatriating foreign profits back to the United States;

• greater difficulty collecting accounts receivable and longer payment cycles;

• less favorable intellectual property laws;

• Regulatory requirements;

• unfamiliarity with foreign laws and regulations; and

• changes in labor conditions and difficulties in staffing and managing international operations.

The volatility of certain raw material costs may adversely affect operations and competitive price advantages for products that incorporate our technology.

Most of the chemicals and other key materials that we use in our business, such as minerals, fiber materials, and packaging materials, are neither generally scarce nor price sensitive, but prices for such chemicals and materials can be cyclical. SAP beads, which are a petrochemical derivative, have been subject to periodic scarcity and price volatility from time to time during recent years, although prices are relatively stable at present. Should the volume of our sales increase dramatically, we may have difficulty obtaining SAP beads or other raw materials at a favorable price. Supply and demand factors, which are beyond our control, generally affect the price of our raw materials. We try to minimize the effect of price increases through production efficiency and the use of alternative suppliers. If we are unable to minimize the effects of increased raw material costs, our business, financial condition, results of operations and cash flows may be materially adversely affected.

Our common stock is thinly traded and largely illiquid.

Our stock is currently quoted on the OTC Markets (OTCQB). Being quoted on the OTCQB has made it more difficult to buy or sell our stock and from time to time has led to a significant decline in the frequency of trades and trading volume. Continued trading on the OTCQB will also likely adversely affect our ability to obtain financing in the future due to the decreased liquidity of the our shares and other restrictions that certain investors have for investing in OTCQB traded securities. While we intend to seek listing on the Nasdaq Stock Market (“Nasdaq”) or another stock exchange when the Company is eligible, there can be no assurance when or if our common stock will be listed on Nasdaq or another stock exchange.

- 19 -

The market price of our stock is subject to volatility.

Because our stock is thinly traded, its price can change dramatically over short periods, even in a single day. An investment in our stock is subject to such volatility and, consequently, is subject to significant risk. The market price of our common stock could fluctuate widely in response to many factors, including:

       •           developments with respect to patents or proprietary rights;

       •           announcements of technological innovations by us or our competitors;

       •           announcements of new products or new contracts by us or our competitors;

       •           actual or anticipated variations in our operating results due to the level of development expenses and other factors;

       •           changes in financial estimates by securities analysts and whether any future earnings of ours meet or exceed such estimates;

       •           conditions and trends in our industry;

       •           new accounting standards;

       •           general economic, political and market conditions and other factors; and

       •           the occurrence of any of the risks described in this Report.

You may have difficulty selling our shares because they are deemed “penny stocks”.

Because our common stock is not quoted on the Nasdaq National Market or Nasdaq Capital Market or listed on a national securities exchange, if the trading price of our common stock remains below $5.00 per share, which we expect for the foreseeable future, trading in our common stock will be subject to the requirements of certain rules promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which require additional disclosure by broker-dealers in connection with any trades involving a stock defined as a penny stock (generally, any non-Nasdaq equity security that has a market price of less than $5.00 per share, subject to certain exceptions). Such rules require the delivery, prior to any penny stock transaction, of a disclosure schedule explaining the penny stock market and the risks associated therewith and impose various sales practice requirements on broker-dealers who sell penny stocks to persons other than established customers and accredited investors (generally defined as an investor with a net worth in excess of $1,000,000 or annual income exceeding $200,000 individually or $300,000 together with a spouse). For these types of transactions, the broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written consent to the transaction prior to the sale. The broker-dealer also must disclose the commissions payable to the broker-dealer, current bid and offer quotations for the penny stock and, if the broker-dealer is the sole market-maker, the broker-dealer must disclose this fact and the broker-dealer’s presumed control over the market. Such information must be provided to the customer orally or in writing before or with the written confirmation of trade sent to the customer. Monthly statements must be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks. The additional burdens imposed upon broker-dealers by such requirements could discourage broker-dealers from effecting transactions in our common stock, which could severely limit the market liquidity of the common stock and the ability of holders of the common stock to sell their shares.

Because our shares are deemed “penny stocks”, new rules make it more difficult to remove restrictive legends.

Rules put in place by FINRA require broker-dealers to perform due diligence before depositing unrestricted common shares of penny stocks, and as such, some broker-dealers, including large national firms, are refusing to deposit unrestricted common shares of penny stocks. As such, it may be more difficult for purchases of shares in our private securities offerings to deposit the shares with broker-dealers and sell those shares on the open market.

The closing bid price for our common stock on March 28, 2014, was $0.43 per share. As of such date, there were approximately 660 registered owners of our common stock. We believe that the number of beneficial owners is substantially higher than this amount.

Dividends

We have never declared or paid a cash dividend to stockholders. We intend to retain any earnings which may be generated in the future to finance operations.

We have one equity compensation plan approved by our stockholders – the 2007 Equity Incentive Plan (the “2007 Plan”). The 2007 Plan was adopted by our Board of Directors on August 7, 2007 and approved by our stockholders at the 2007 Annual Meeting of Stockholders on September 6, 2007, and amended by our stockholders in 2011. Upon the adoption of the 2007 Plan, a prior plan approved in 2004 was frozen and no further grants will be made under that. It currently allows the issuance of a maximum aggregate 12,000,000 shares.

(2)

This includes various issuances to specific individuals either as a conversion of un-paid obligations or as part of their agreement for services. Each issuance is itself a plan and additional detail is available in Note 9 of our financial statements.

Sales of Unregistered Securities

The following is a report of the sales of unregistered securities not previously reported in a Quarterly Report on Form 10-Q or in a Current Report on Form 8-K.

On December 31 2013, we issued 270,900 shares of our common stock, at a conversion price of $0.25 per share, our common stock on the day of issuance, to our Chief Science Officer in lieu of $67,725 in accrued and unpaid payables for his services. The stock issued is restricted from sale until the earlier of the termination of the executive’s employment, or the filing of a report of a “change in control” on Form 8-K.

On December 31 2013, we issued 247,204 shares of our common stock, at a conversion price of $0.25 per share, our common stock on the day of issuance, to our President in lieu of $61,801 in accrued and unpaid payables for his services. The stock issued is restricted from sale until the earlier of the termination of the executive’s employment, or the filing of a report of a “change in control” on Form 8-K.

On December 17, 2012, our subsidiary Clyra (see Note 12) began a private securities offering, selling up to 1,000 shares of its common stock at $1,000 per share. On December 16, 2013 we sold 25 shares of its common stock to one accredited investor and received $25,000 gross and $25,000 net proceeds from the sale.

In April 2013, Clyra modified the terms of its offering, such that, in addition to shares of Clyra common stock, each Clyra investor would receive a warrant (“Clyra 2012 Warrants”) to purchase an additional number of shares of Clyra common stock as originally purchased by the investor, at a price of $1,833 per share, until July 30, 2015. The offering terms were also modified to increase the number of shares of BioLargo common stock into which the Clyra investor could convert his or her Clyra shares, from 2,858 to 3,333 and 1/3 shares of BioLargo common stock. The date until which the investor may tender Clyra shares to BioLargo for conversion was extended to July 30, 2015. The Clyra investors will not receive any further warrants to purchase additional BioLargo common stock.

Pursuant to a private offering of our common stock at a price of $0.25 per share that commenced June 2013, on October 10, 2013, pursuant to the terms of our Summer 2013 Offering, one investor purchased 40,000 shares for $10,000.

Each purchaser of stock will receive, for no additional consideration, a stock purchase warrant which entitles the holder to purchase a number of additional shares of our common stock equal to the number of shares originally purchased. The warrant is exercisable at $0.30 per share, will expire on October 15, 2015, and is subject to a call provision in the event BioLargo’s common stock price reaches $0.60 per share over a period of 40 days.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and the related notes to the consolidated financial statements included elsewhere in this report.

This discussion contains forward-looking statements that involve risks and uncertainties. Such statements, which include statements concerning future revenue sources and concentration, selling, general and administrative expenses, research and development expenses, capital resources, additional financings and additional losses, are subject to risks and uncertainties, including, but not limited to, those discussed above in Part I, Item 1 and elsewhere in this Annual Report, particularly in “Risk Factors,” that could cause actual results to differ materially from those projected. The forward-looking statements set forth in this Annual Report are as of December 31, 2013 unless expressly stated otherwise, and we undertake no duty to update this information.

Results of Operations—Comparison of the years ended December 31, 2013 and 2012

Revenue

We generated revenue totaling $167,946 during the year ended December 31, 2013, compared with $65,542 during the year ended December 31, 2012. Included in the 2013 revenue is $100,000 in license revenue from the deposit related to the Central Garden transaction. See Note 3 of our financial statements for additional information. In 2013 we generated product revenue totaling $67,946, which consisted primarily of sales of our Odor-No-More branded products, and Deodorall branded products. In 2012 we generated product revenue totaling $65,542, which consisted primarily of sales of our Odor-No-More branded products.

Cost of Goods Sold

Our cost of goods sold during 2013 was $29,656, or 44% of product revenues, as compared with $39,781 in 2012, or 61% of 2012 revenues. Our cost of goods sold includes costs of raw materials, contract manufacturing, and portions of salaries related to the product development and manufacturing. Because we have not achieved a large or consistent revenue base, the inclusion of the fixed costs related to the product development and manufacturing increases our cost of goods disproportionately, resulting in higher fluctuations. The difference in the percentage of product revenues in 2013 versus 2012 is due to such fluctuations.

Selling, General and Administrative Expense

Selling, General and Administrative expenses were $2,004,777 for the year ended December 31, 2013, compared to $4,354,414 for the year ended December 31, 2012, a decrease of $2,349,637. The decrease is primarily related to non-cash cash transactions which occurred in 2012 and did not occur in 2013. The largest components of the decrease in selling, general and administrative expenses were:

a. Salaries and Payroll-related Expenses: These expenses were $551,753 for the year ended December 31, 2013, compared to $1,278,765 for the year ended December 31, 2012, a decrease of $727,012. The decrease is primarily attributable to fair value of the common stock issuance and the amortization of the fair value of the options issued to senior executives in 2012 compared to no option issuances in 2013.

b. Consulting Expenses: These expenses were $377,569 for the year ended December 31, 2013, compared to $1,714,493 for the year ended December 31, 2012, a decrease of $1,336,924. The decrease is primarily attributable to the amortization of the fair value of an option issued to a consultant, and the fair value of an extension of an option issued to two consultants, resulting in a non-cash stock option compensation expense in 2012, but no such expense for that option in 2013.

- 24 -

c. Professional Fees: These expenses were $433,322 for the year ended December 31, 2013, compared to $454,487 for the year ended December 31, 2012, a decrease of $21,165. The use of and payment to professionals were consistent between 2013 and 2012.

Research and Development

Research and development expenses were $742,247 for the year ended December 31, 2013, compared to $383,549 for the year ended December 31, 2012, an increase of $358,698. The increase is due to additional product development activities associated with the development of our advanced wound care products, water treatment and oil and gas products.

Interest expense

Interest expense totaled $281,591 for the year ended December 31, 2013, compared to $616,354 for the year ended December 31, 2012, a decrease of $334,763. The decrease is primarily due to a reduction of interest expense related to our Spring 2009 and Spring 2010 offerings which were converted into shares of our common stock in 2012. This was offset by the fair value of the warrants issued in connection with extending the expiration date of our Winter 2012 Warrants.

Net Loss

Net loss for the year ended December 31, 2013 was $2,901,245, a loss of $0.04 per share, compared to a net loss for the year ended December 31, 2012 of $5,333,986, a loss of $0.08 per share. The decrease in net loss for the year ended December 31, 2013 is primarily attributable to the decrease in Selling, General and Administrative expenses, and the reduction of interest expense, partially offset by the increase in research and development expenses.

Liquidity and Capital Resources

We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Until we are successful in commercializing products or negotiating and securing payments for licensing rights from prospective licensing candidates, we expect to continue to have operating losses. Cash and cash equivalents totaled $92,437 at December 31, 2013. We had negative working capital of $605,961 as of December 31, 2013, compared with negative working capital of $341,589 as of December 31, 2012. We had negative cash flow from operating activities of $1,212,252 for the year ended December 31, 2013, compared to a negative cash flow from operating activities of $2,032,804 for the year ended December 31, 2012. We used cash from financing activities to fund operations.  Our cash position is insufficient to meet our continuing anticipated expenses or fund anticipated operating expenses. Accordingly, we will be required to raise significant additional capital to sustain operations and further implement our business plan and we may be compelled to reduce or curtail certain activities to preserve cash. See Note 1 for a discussion of the presentation and preparation of the financial statements on a going concern basis.

Since we continue to be limited in terms of our capital resources, we are continuing to raise investment funds through private securities offerings. During the year ended December 31, 2013, we received gross proceeds of $1,153,500 from our financing activities. (See Note 5 and Note 11). We will be required to raise substantial additional capital to continue our current operations, as well as to meet our liabilities as they become due, if our efforts to commercialize our technology do not generate cash flow in the near future. There can be no assurance that we will be able to do so. If we are unable to do so, and our operations do not generate sufficient cash, we will be compelled to reduce or curtail certain activities to preserve cash, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property. If we were forced to significantly curtail aspects of our operations, there would be a material adverse impact on our future outlook, as well as our current financial condition and results of operations.

- 25 -

It is also unlikely that we will be able to qualify for bank or other financial institutional debt financing until such time as our operations are considerably more advanced and we are able to demonstrate the financial strength to provide confidence for a lender.

Critical Accounting Policies

Our discussion and analysis of our results of operations and liquidity and capital resources are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, valuation of intangible assets and investments, and share-based payments. We base our estimates on anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results that differ from our estimates could have a significant adverse effect on our operating results and financial position. We believe that the following significant accounting policies and assumptions may involve a higher degree of judgment and complexity than others.

The methods, estimates and judgments the Company uses in applying these most critical accounting policies have a significant impact on the results of the Company reports in its financial statements.

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

Valuation of Intangibles and Investments Acquired in a Non-Monetary Transaction

The Company has established a policy relative to the methodology to determine the value assigned to each intangible acquired with or licensed by the Company and/or services or products received for non-cash consideration of the Company’s common stock. The value is based on the market price of the Company’s common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received, as adjusted for applicable discounts.

- 26 -

Share-based Payments

It the Company’s policy to expense share based payments as of the date of grant in accordance with Auditing Standard Codification Topic 718 “Share-Based Payment.” Application of this pronouncement requires significant judgment regarding the assumptions used in the selected option pricing model, including stock price volatility and employee exercise behavior. Most of these inputs are either highly dependent on the current economic environment at the date of grant or forward-looking expectations projected over the expected term of the award. As a result, the actual impact of adoption on future earnings could differ significantly from our current estimate.

Recent Accounting Pronouncements

No recent accounting pronouncements or other authoritative guidance have been issued that management considers likely to have a material impact on our consolidated financial statements.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We conducted an evaluation, under the supervision and with the participation of management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Annual Report.

Our procedures have been designed to ensure that the information relating to our company, including our consolidated subsidiaries, required to be disclosed in our SEC reports is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow for timely decisions regarding required disclosure. Based on this evaluation, our chief executive officer and chief financial officer concluded that as of the evaluation date our disclosure controls and procedures are effective.

It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Under the supervision and with the participation of our management, including our Chief Executive Officer and the Chief Financial Officer, we have established internal control procedures in accordance with the guidelines established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) for smaller public companies, and through its evaluation of those internal control procedures, our management concluded that our internal controls over financial reporting are effective as of December 31, 2013.

This Annual Report does not include an attestation report of the Company’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to rules of the SEC that permit the company to provide only management’s report in this Annual Report.

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls or our internal control over financial reporting, or any system we design or implement in the future, will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Control

There have not been any changes in our internal control over financial reporting during the year ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

BioLargo, Inc.

We have audited the accompanying consolidated balance sheets of BioLargo, Inc. (the “Company”) as of December 31, 2013 and 2012, and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for each of the years ended December 31, 2013 and 2012. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of BioLargo, Inc. as of December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the years ended December 31, 2013 and 2012, in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses, negative cash flows from operations and has limited capital resources and a net stockholders’ deficit. These matters raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Business and Organization

Outlook

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. As reflected in the accompanying financial statements for the year ended December 31, 2013, we had a net loss of $2,901,245, we had negative working capital of $605,961, current assets of $126,196, and an accumulated deficit of $75,327,603. The foregoing factors raise substantial doubt about our ability to continue as a going concern. Ultimately, our ability to continue as a going concern is dependent upon our ability to attract significant new sources of capital, attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our BioLargo technology. The financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Our total cash and cash equivalents were $92,437 at December 31, 2013. We generated revenues of $167,946 in the year ended December 31, 2013, which amount was not sufficient to fund our operations. We generally have not had enough cash or sources of capital to pay our accounts payable and expenses as they arise, and have relied on the issuance of stock options and common stock, as well as extended payment terms with our vendors, to continue to operate. We will be required to raise substantial additional capital to expand our operations, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property, and possible strategic acquisitions or alliances, as well as to meet our liabilities as they become due for the next 12 months.

As of December 31, 2013, we had $325,000 principal amount outstanding on our notes payable (see Note 11), and $407,157 of outstanding accounts payable. (See Note 10.)

During the year ended December 31, 2013, we received $928,500 net proceeds from our private securities offerings. (See Note 5.) We also received $225,000 net proceeds from three note payable obligations during the three month period ended December 31, 2013. (See Note 11.)

In the opinion of management, the accompanying balance sheets and related statements of operations, cash flows, and stockholders’ equity include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. Actual results and outcomes may differ from management’s estimates and assumptions. Estimates are used when accounting for stock-based transactions, account payables and accrued expenses and taxes, among others.

Organization

We were initially organized under the laws of the State of Florida in 1989, and in 1991 merged into a Delaware corporation. We operate four subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in 2006, Odor-No-More, Inc., organized under the laws of the State of California in 2009, Clyra Medical Technologies, Inc., organized under the laws of the State of California in 2012, and BioLargo Water, Inc., organized under the laws of the State of California in 2013.

Business Overview 

By leveraging our suite of patented and patent-pending intellectual property, which we refer to as the “BioLargo Technology”, our business strategy is to harness and deliver nature’s best disinfectant – iodine – in a safe, efficient, environmentally sensitive and cost-effective manner. The core of this innovative technology is the accurate and safe delivery of iodine in a wide range of forms, moieties and conditions. Iodine is an essential nutrient and all natural broad-spectrum disinfectant with no known microbial resistance. When used effectively, it can keep people and the world safer from disease and infection, and can be engaged as a powerful oxidant and catalyst to keep our water, earth, and air clean, safe, and healthy. Our goal is to target our capabilities to create and utilize iodine to improve the quality of life for people worldwide, to protect the environment, all while producing positive economic results for our customers, partners, and shareholders.

Our products offer a solution to an array of pervasive problems, including odor, moisture control, disinfection, wound healing and contaminated water. The iodine most of us are familiar with, sold in pharmacies and used by hospitals, has severe limitations – it is considered toxic, causes staining, and contains a limited dose of the active oxidizing ingredient. Our technology, on the other hand, directly addresses many of these shortcomings – we can deliver iodine’s oxidizing ingredient (“free iodine”) with precision, ranging from very small doses up to very large doses with more than 20 times the power of traditional iodine. We can deliver iodine so that it is both non-toxic and non-staining, thus extending its usefulness well beyond historical product applications. Consequently, we feel our best advantage is to leverage iodine’s breadth to develop uses and products that offer a competitive edge against other technologies. These uses can secure BioLargo its highest value proposition, resulting in sales and licensing opportunities.

The centerpieces of our technology are embodied by our patented and proprietary CupriDyne^® and its methods of delivery, the Isan™ system, and our “BioLargo® AOS Filter (“Advanced Oxidation System”). These technologies offer a nearly seamless range of capabilities for the generation, delivery and control of iodine and implementation of iodine in most of its moieties.

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As of December 31, 2013, the consolidation includes four subsidiaries, BioLargo Life Technologies, Inc., Odor-No-More, Inc., Clyra Medical Technologies, Inc., and BioLargo Water, Inc.

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less or money market funds from substantial financial institutions to be cash equivalents. We place substantially all of our cash and cash equivalents with one financial institution. As of December 31, 2013, our cash deposits were less than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner. From time to time during the year we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the institution, however, we do not anticipate non-performance.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts was $5,000 and $3,818 at December 31, 2012 and December 31, 2013, respectively.

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

		December 31, 2012		December 31, 2013
Raw materials	$	43,395	$	26,080
Finished goods (Note 4)		10,590		3,750
	$	53,985	$	29,830

Equipment

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets, which is three years. As of December 31, 2012 and 2013, our equipment was fully depreciated.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2012 and 2013, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, uncollectible accounts receivable, asset depreciation and amortization, and taxes, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Payments

All share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

Income Taxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

BIOLARGO, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

Fair Value of Financial Instruments

The carrying amounts of the Company's financial instruments as of December 31, 2012 and 2013 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, accounts payable, convertible notes, and other assets and liabilities.

Recent Accounting

No recent accounting pronouncements or other authoritative guidance have been issued that management considers likely to have a material impact on our consolidated financial statements.

Note 3. Customer Deposit

On March 24, 2011, we entered into a contract in which Central Garden & Pet Company (“Central”) was granted the exclusive worldwide right and license to sell, market, offer for sale, distribute import, export, and otherwise exploit products that contain the BioLargo technologies in the “pet supplies industry” (which is defined in the agreement, and does not include products for equine or livestock). Pursuant to the Central contract, we received a $100,000 non-refundable deposit which would be credited against future orders, if any.  

On February 11, 2013, we gave Central written notice of their failure to purchase the minimum required product from us to maintain exclusive rights to our technology in the “pet supplies industry” pursuant to the agreement. To maintain exclusive rights, within 60 days of our written notice Central must have either purchased the minimum amount of product or compensate us for lost profits as if they had done so.

Central failed to purchase products from us prior to the expiration of the 60-day period, and failed to otherwise compensate us for lost profits. As such, as of April 12, 2013, Central lost its exclusive rights to our technology in the “pet supplies industry”, and we recorded as revenue the $100,000 deposit paid in 2011.

Note 4. Deferred Revenue

Horn Warehouse

Horn (formerly the E.T. Horn Company) has warehoused our product and made it available to us for later sales. Thus, for revenue recognition purposes, prior sales to Horn have been deferred until such time the product is sold to retailers and/or end-users. As of May 15, 2013, Horn no longer provides warehouse services and there is no obligation for us to sell inventory held at Horn.

Note 7. Warrants

We have certain warrants outstanding to purchase our common stock, at various prices, as described in the following table:

	Number of Shares			Price Range
Outstanding as of December 31, 2011		5,077,086		$0.125	–	$ 1.00
Issued		6,398,813	(1)		$0.50
Exercised		—			—
Expired		(2,870,871	)	$0.75	–	$2.00
Outstanding as of December 31, 2012		8,390,741		$0.125	–	$1.00
Issued		3,503,328		$0.25	–	$0.50
Exercised		—			—
Expired		(1,275,298	)	$0.50	–	$1.00
Outstanding as of December 31, 2013		10,618,771		$0.125	–	$1.00

⁽¹⁾ During 2012, an adjustment was made to the timing of the issuance of warrants to purchase an aggregate 214,287 shares.

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option-pricing model and the calculated value is amortized over the life of the warrant. The determination of expense of warrants issued for services or settlement also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

	2012			2013
Risk free interest rate	0.15%	–	0.57%	0.15%	–	0.78%
Expected volatility	120%	–	489%	112%	–	262%
Expected dividend yield		—			—
Forfeiture rate		—			—
Expected life in years	0.75	–	5.00	1.00	–	3.00

The risk-free interest rate is based on U.S Treasury yields in effect at the time of grant. Expected volatilities are based on historical volatility of our common stock. The expected life in years is presumed to be the mid-point between the vesting date and the end of the contractual term.

We recorded $509,940 and $247,412 of interest expense related to the amortization of the discount on convertible notes, for the extension of warrants set to expire, and for the fair value of warrants issued for services for the years ended December 31, 2012 and 2013, respectively.

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model. The following methodology and assumptions were used to calculate share based compensation for the year ended December 31, 2013:

	2012						2013
	Non Plan			2007 Plan			Non Plan			2007 Plan
Risk free interest rate	0.89%	–	1.73%	1.50%	–	2.06%	2.66%	–	3.04%		2.19	%
Expected volatility	483%	–	949%	520%	–	951%	928%	–	951%		928	%
Expected dividend yield		—			—			—			—
Forfeiture rate		—			—			—			—
Expected life in years	4	–	10	7	-	10		10			10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future.

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model. Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

BIOLARGO, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 12. Provision for Income Taxes

Given our historical losses from operations, income taxes have been limited to the minimum franchise tax assessed by the State of California.

At December 31, 2013 we had federal and California tax net operating loss carry-forwards of approximately $38 million. Due to changes in our ownership through various common stock issuances during 2002 and 2007, the utilization of net operating loss carry-forwards may be subject to annual limitations and discounts under provisions of the Internal Revenue Code. Such limitations could result in the permanent loss of a significant portion of the net operating loss carry-forwards. Realization of our deferred tax assets, which relate to operating loss carry-forwards and timing differences, is dependent on future earnings. The timing and amount of future earnings are uncertain and therefore we have established a 100% valuation allowance.

At December 31, 2013, our U.S. Federal and California State income tax returns related to the years 2010-2013 remain open to examination by tax authorities. However, given our history of net operating losses, as discussed above, the statute of limitations could remain open to examine years prior to 2007 for the year(s) in which net operating losses were originally incurred if/when we reach profitability and begin to utilize our net operating losses to offset taxable income.

Note 13. Noncontrolling Interest

In May 2012, we formed a subsidiary for the purpose of marketing and selling medical products containing our technology, Clyra Medical Technology, Inc. (“Clyra”). Until December 17, 2012, this subsidiary was wholly owned, with 7,500 shares issued to BioLargo, Inc. On December 17, 2012, Clyra signed executive employment agreements with three individuals, in which each was granted 500 shares of Clyra common stock, one-third of which vested immediately, and the remaining over time. The shares granted to the three executives are restricted from transfer until a sale of the company, whether by means of a sale of its stock or substantially all of its assets, or otherwise by agreement of Clyra, BioLargo and the executives. 

Clyra has also raised $236,000 in net proceeds through issuing 240 shares of its common stock during the year ended December 31, 2013. (see Note 5, “Private Securities Offerings”). The holdings of the executive officers and investors represent18.8% of the issued and outstanding stock of the company.

For the year ended December 31, 2013, there have been no revenues and the financial impact of Clyra’s operations resulted in a net loss of $372,922.

Note 14. Subsequent Events.

Management has evaluated subsequent events through the date of the filing of this Annual Report and management noted the following for disclosure.

Summer 2013 Offering

Pursuant to a private offering of our common stock at a price of $0.25 per share that commenced June 2013 and subsequent to December 31, 2013 we sold 1,516,663 shares of our common stock to nine accredited investors and received $455,000 gross proceeds from the sales.

[1] On April 27, 2009, in an effort to preserve the Company's cash and reduce outstanding payables, the Board offered to officers and board members an option ("Option") to purchase 485,100 shares of our common stock in lieu of cash payment to reduce amounts owed by the Company. The Options were issued pursuant to the Company's 2007 Equity Incentive Plan with an exercise price of $0.50 cents a share, an amount which was $0.20 per share above the $0.30 per share closing price of the Company's common stock on April27, 2009, and had an expiration date of April 27, 2012. The Options issued to Board members Dennis P. Calvert and Kenneth R. Code were issued at an exercise price of $0.55 per share. In consideration of the circumstances in which the Options were issued, and the fact that the price of the Company's common stock was less than the strike price of the Options, the Board extended the expiration date of the Options by a period of seven years, to expire on April 27, 2019. The fair value of the Option totaled $218,295 and was recorded as selling, general and administrative expense. On July 5, 2012, our independent board members were issued options to purchase an aggregate 435,161 shares of our common stock at $0.36 per share in exchange for a reduction of $104,439 in accrued and unpaid obligations for their services on the board of directors. The share price of our common stock on July 5, 2012 was $0.32 per share. These options are fully vested and expire ten years from the date of issuance, July 5, 2022. The fair value of the options was an aggregate $152,585, resulting in additional $48,146 of selling, general and administrative expense in the year ended December 31, 2013.

[2] On April 9, 2012, we issued an option to purchase 300,000 shares of common stock to our Chief Financial Officer in exchange for his services pursuant to the April 2012 extension of his engagement agreement with an exercise price of $0.35 per share, resulting in $105,000 in selling, general and administrative expense. The option expires April 9, 2022. On July 1, 2012, we recorded the issuance of an option to purchase an aggregate 46,667 shares of our common stock to the independent members of our Board of Directors, pursuant to the terms of the 2007 Equity Plan which calls for an automatic issuance of an option to a new board of director and concurrently with the annual stockholders meeting to our returning board of directors. The options vest after a period of one year from the date of grant, expires ten years from the date of issuance, and 6,667 is exercisable at $0.34 per share and 40,000 shares is exercisable at $0.40 per share, the price of our common stock on the grant date. The fair value of these options totaled $15,067 and was recorded as selling, general and administrative expense.

[3] On April 27, 2009, in an effort to preserve the Company's cash and reduce outstanding payables, the Board offered to third parties an option ("Option") to purchase 257,035shares of our common stock in lieu of cash payment to reduce amounts owed by the Company. The Options were issued pursuant to the Company's 2007 Equity Incentive Plan with an exercise price of $0.50 cents a share, an amount which was $0.20 per share above the $0.30 per share closing price of the Company's common stock on April 27, 2009, and had an expiration date of April 27, 2012. In consideration of the circumstances in which the Options were issued, and the fact that the price of the Company's common stock was less than the strike price of the Options, the Board extended the expiration date of the Options by a period of seven years, to expire on April 27, 2019. The fair value of the Option totaled $115,666 and was recorded as selling, general and administrative expense during the year-ended December 31, 2013.

[4] On July 18, 2012, an option was issued to a consultant, in accordance with the service agreement, to purchase an aggregate 200,000 shares of our common stock. Of this amount 50,000 vested upon issuance exercisable at $0.50 per share; 50,000 vest January 18, 2013 at an exercise price of $0.75 per share; 50,000 vest July 18, 2013 at an exercise price of $1.00 per share; and the remaining 50,000 vest January 18, 2014 at an exercise price of $1.25 per share. The share price of our common stock on the date of issuance was $0.28 per share and resulted in a fair value of $56,000, of which $14,000 was recorded as selling, general and administrative expense during the year ended December 31, 2013, and the remaining will be expensed ratably per the vesting schedule. These options expire ten years from the date of issuance, July 18, 2022.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As of December 31, 2013, the consolidation includes four subsidiaries, BioLargo Life Technologies, Inc., Odor-No-More, Inc., Clyra Medical Technologies, Inc., and BioLargo Water, Inc.

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less or money market funds from substantial financial institutions to be cash equivalents. We place substantially all of our cash and cash equivalents with one financial institution. As of December 31, 2013, our cash deposits were less than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner. From time to time during the year we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the institution, however, we do not anticipate non-performance.

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts was $5,000 and $3,818 at December 31, 2012 and December 31, 2013, respectively.

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

		December 31, 2012		December 31, 2013
Raw materials	$	43,395	$	26,080
Finished goods (Note 4)		10,590		3,750
	$	53,985	$	29,830

Equipment

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets, which is three years. As of December 31, 2012 and 2013, our equipment was fully depreciated.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2012 and 2013, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, uncollectible accounts receivable, asset depreciation and amortization, and taxes, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Payments

All share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

During the years ended December 31, 2012 and 2013 we recorded an aggregate $657,479 and $39,200 in selling, general and administrative expense related to options issued pursuant to the 2007 Plan. (See Note 9).

During the years ended December 31, 2012 and 2013 we recorded an aggregate $1,096,412 and $892,309 in selling, general and administrative expense related to options issued outside of the 2007 Plan. (See Note 9).

During the year ended December 31, 2013 we issued 1,483,764 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $419,224. (See Note 10).

During the year ended December 31, 2012 we issued 1,117,113 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $335,134. (See Note 10).

During the years ended December 31, 2012 and 2013 we recorded an aggregate $509,940 and $247,412 of interest expense related to the amortization of the discount on convertible notes (see Note 5), for the extension of warrants set to expire, and for the fair value of warrants issued for services (see Note 9).

Pursuant to the recommendations from our Compensation Committee, on December 28, 2012 we issued 1,000,000 shares of common stock to three of our executive officers for their continued service at $0.25 per share and recorded $250,000 of selling, general and administrative expense.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

IncomeTaxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

Fair Value of Financial Instruments

The carrying amounts of the Company's financial instruments as of December 31, 2012 and 2013 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, accounts payable, convertible notes, and other assets and liabilities.

Recent Accounting

No recent accounting pronouncements or other authoritative guidance have been issued that management considers likely to have a material impact on our consolidated financial statements.

Note 1. Business and Organization

Outlook

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. As reflected in the accompanying financial statements for the year ended December 31, 2013, we had a net loss of $2,901,245, we had negative working capital of $605,961, current assets of $126,196, and an accumulated deficit of $75,327,603. The foregoing factors raise substantial doubt about our ability to continue as a going concern. Ultimately, our ability to continue as a going concern is dependent upon our ability to attract significant new sources of capital, attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our BioLargo technology. The financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

We have been, and anticipate that we will continue to be, limited in terms of our capital resources. Our total cash and cash equivalents were $92,437 at December 31, 2013. We generated revenues of $167,946 in the year ended December 31, 2013, which amount was not sufficient to fund our operations. We generally have not had enough cash or sources of capital to pay our accounts payable and expenses as they arise, and have relied on the issuance of stock options and common stock, as well as extended payment terms with our vendors, to continue to operate. We will be required to raise substantial additional capital to expand our operations, including without limitation, hiring additional personnel, additional scientific and third-party testing, costs associated with obtaining regulatory approvals and filing additional patent applications to protect our intellectual property, and possible strategic acquisitions or alliances, as well as to meet our liabilities as they become due for the next 12 months.

As of December 31, 2013, we had $325,000 principal amount outstanding on our notes payable (see Note 11), and $407,157 of outstanding accounts payable. (See Note 10.)

During the year ended December 31, 2013, we received $928,500 net proceeds from our private securities offerings. (See Note 5.) We also received $225,000 net proceeds from three note payable obligations during the three month period ended December 31, 2013. (See Note 11.)

In the opinion of management, the accompanying balance sheets and related statements of operations, cash flows, and stockholders’ equity include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. Actual results and outcomes may differ from management’s estimates and assumptions. Estimates are used when accounting for stock-based transactions, account payables and accrued expenses and taxes, among others.

Organization

We were initially organized under the laws of the State of Florida in 1989, and in 1991 merged into a Delaware corporation. We operate four subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in 2006, Odor-No-More, Inc., organized under the laws of the State of California in 2009, Clyra Medical Technologies, Inc., organized under the laws of the State of California in 2012, and BioLargo Water, Inc., organized under the laws of the State of California in 2013.

Business Overview 

By leveraging our suite of patented and patent-pending intellectual property, which we refer to as the “BioLargo Technology”, our business strategy is to harness and deliver nature’s best disinfectant – iodine – in a safe, efficient, environmentally sensitive and cost-effective manner. The core of this innovative technology is the accurate and safe delivery of iodine in a wide range of forms, moieties and conditions. Iodine is an essential nutrient and all natural broad-spectrum disinfectant with no known microbial resistance. When used effectively, it can keep people and the world safer from disease and infection, and can be engaged as a powerful oxidant and catalyst to keep our water, earth, and air clean, safe, and healthy. Our goal is to target our capabilities to create and utilize iodine to improve the quality of life for people worldwide, to protect the environment, all while producing positive economic results for our customers, partners, and shareholders.

Our products offer a solution to an array of pervasive problems, including odor, moisture control, disinfection, wound healing and contaminated water. The iodine most of us are familiar with, sold in pharmacies and used by hospitals, has severe limitations – it is considered toxic, causes staining, and contains a limited dose of the active oxidizing ingredient. Our technology, on the other hand, directly addresses many of these shortcomings – we can deliver iodine’s oxidizing ingredient (“free iodine”) with precision, ranging from very small doses up to very large doses with more than 20 times the power of traditional iodine. We can deliver iodine so that it is both non-toxic and non-staining, thus extending its usefulness well beyond historical product applications. Consequently, we feel our best advantage is to leverage iodine’s breadth to develop uses and products that offer a competitive edge against other technologies. These uses can secure BioLargo its highest value proposition, resulting in sales and licensing opportunities.

The centerpieces of our technology are embodied by our patented and proprietary CupriDyne^® and its methods of delivery, the Isan™ system, and our “BioLargo® AOS Filter (“Advanced Oxidation System”). These technologies offer a nearly seamless range of capabilities for the generation, delivery and control of iodine and implementation of iodine in most of its moieties.

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As of December 31, 2013, the consolidation includes four subsidiaries, BioLargo Life Technologies, Inc., Odor-No-More, Inc., Clyra Medical Technologies, Inc., and BioLargo Water, Inc.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less or money market funds from substantial financial institutions to be cash equivalents. We place substantially all of our cash and cash equivalents with one financial institution. As of December 31, 2013, our cash deposits were less than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner. From time to time during the year we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the institution, however, we do not anticipate non-performance.

Receivables, Policy [Policy Text Block]

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts was $5,000 and $3,818 at December 31, 2012 and December 31, 2013, respectively.

Inventory, Policy [Policy Text Block]

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of:

		December 31, 2012		December 31, 2013
Raw materials	$	43,395	$	26,080
Finished goods (Note 4)		10,590		3,750
	$	53,985	$	29,830

Property, Plant and Equipment, Policy [Policy Text Block]

Equipment

Equipment is carried at cost and depreciated using the straight-line method over the estimated useful lives of the assets, which is three years. As of December 31, 2012 and 2013, our equipment was fully depreciated.

Earnings Per Share, Policy [Policy Text Block]

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2012 and 2013, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, uncollectible accounts receivable, asset depreciation and amortization, and taxes, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Share-based Payments

All share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their fair values.

For stock issued to consultants and other non-employees for services, we record the expense based on the fair market value of the securities as of the date of the stock issuance. The issuance of stock warrants or options to non-employees are valued at the time of issuance utilizing the Black Scholes calculation and the amount is charged to expense.

During the years ended December 31, 2012 and 2013 we recorded an aggregate $657,479 and $39,200 in selling, general and administrative expense related to options issued pursuant to the 2007 Plan. (See Note 9).

During the years ended December 31, 2012 and 2013 we recorded an aggregate $1,096,412 and $892,309 in selling, general and administrative expense related to options issued outside of the 2007 Plan. (See Note 9).

During the year ended December 31, 2013 we issued 1,483,764 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $419,224. (See Note 10).

During the year ended December 31, 2012 we issued 1,117,113 shares of our common stock to our President, Chief Technology Officer and Secretary in lieu of accrued and unpaid compensation and unreimbursed expenses totaling $335,134. (See Note 10).

During the years ended December 31, 2012 and 2013 we recorded an aggregate $509,940 and $247,412 of interest expense related to the amortization of the discount on convertible notes (see Note 5), for the extension of warrants set to expire, and for the fair value of warrants issued for services (see Note 9).

Pursuant to the recommendations from our Compensation Committee, on December 28, 2012 we issued 1,000,000 shares of common stock to three of our executive officers for their continued service at $0.25 per share and recorded $250,000 of selling, general and administrative expense.

Non-Cash Transactions [Policy Text Block]

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

Revenues are recognized as risk and title to products transfers to the customer (which generally occurs at the time shipment is made), the sales price is fixed or determinable, and collectability is reasonably assured. We also may generate revenues from royalties and license fees from our intellectual property. Licensees typically pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. License fees are recognized over the estimated period of future benefit to the average licensee.

Income Tax, Policy [Policy Text Block]

IncomeTaxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

The carrying amounts of the Company's financial instruments as of December 31, 2012 and 2013 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, accounts payable, convertible notes, and other assets and liabilities.

Note 11. Note Payables

On June 8, 2010, we received $100,000 and issued a promissory note with an initial maturity date of December 3, 2010, which accrues interest at a rate of 10%. The noteholder, for no additional consideration, received a stock purchase warrant entitling the holder to purchase 50,000 shares of our common stock, exercisable at $0.50 per share until June 3, 2013. (See Note 7.) The maturity date of the note was extended to December 3, 2011, to December 3, 2012, and again to January 14, 2015. (See Note 14, Subsequent Events.)

On December 28, 2012, the note holder agreed to extend the maturity date of the note by a period of one year to December 31, 2013.

As of May 15, 2013, Horn no longer provides warehouse services and there is no obligation for us to sell inventory held at Horn.

Note 12. Provision for Income Taxes

Given our historical losses from operations, income taxes have been limited to the minimum franchise tax assessed by the State of California.

At December 31, 2013 we had federal and California tax net operating loss carry-forwards of approximately $38 million. Due to changes in our ownership through various common stock issuances during 2002 and 2007, the utilization of net operating loss carry-forwards may be subject to annual limitations and discounts under provisions of the Internal Revenue Code. Such limitations could result in the permanent loss of a significant portion of the net operating loss carry-forwards. Realization of our deferred tax assets, which relate to operating loss carry-forwards and timing differences, is dependent on future earnings. The timing and amount of future earnings are uncertain and therefore we have established a 100% valuation allowance.

At December 31, 2013, our U.S. Federal and California State income tax returns related to the years 2010-2013 remain open to examination by tax authorities. However, given our history of net operating losses, as discussed above, the statute of limitations could remain open to examine years prior to 2007 for the year(s) in which net operating losses were originally incurred if/when we reach profitability and begin to utilize our net operating losses to offset taxable income.

Note 7. Warrants

We have certain warrants outstanding to purchase our common stock, at various prices, as described in the following table:

	Number of Shares			Price Range
Outstanding as of December 31, 2011		5,077,086		$0.125	–	$ 1.00
Issued		6,398,813	(1)		$0.50

Outstanding as of December 31, 2013		10,618,771		$0.125	–	$1.00

⁽¹⁾ During 2012, an adjustment was made to the timing of the issuance of warrants to purchase an aggregate 214,287 shares.

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option-pricing model and the calculated value is amortized over the life of the warrant. The determination of expense of warrants issued for services or settlement also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

	2012			2013
Risk free interest rate	0.15%	–	0.57%	0.15%	–	0.78%
Expected volatility	120%	–	489%	112%	–	262%
Expected dividend yield		—			—
Forfeiture rate		—			—
Expected life in years	0.75	–	5.00	1.00	–	3.00

The risk-free interest rate is based on U.S Treasury yields in effect at the time of grant. Expected volatilities are based on historical volatility of our common stock. The expected life in years is presumed to be the mid-point between the vesting date and the end of the contractual term.

We recorded $509,940 and $247,412 of interest expense related to the amortization of the discount on convertible notes, for the extension of warrants set to expire, and for the fair value of warrants issued for services for the years ended December 31, 2012 and 2013, respectively.

Summer 2013 Warrants

These warrants are set to expire October 15, 2015.

Winter 2013 Warrants

 Pursuant to the terms of our Winter 2013 Offering (see Note 5), during 2013 we issued warrants to purchase up to an aggregate 2,333,329 shares of our common stock to the investors in the Winter 2013 Offering at an exercise price of $0.55 per share. These warrants are set to expire June 15, 2015.

The offering terms were also modified to increase the number of shares of BioLargo common stock into which the Clyra investor could convert his or her Clyra shares, from 2,858 to 3,333 and 1/3 shares of BioLargo common stock. We have issued warrants to purchase up to an aggregate 799,999 shares of our common stock to the investors in the Clyra Winter 2012 private securities offering. (See Note 5). The date until which the investor may tender Clyra shares to BioLargo for conversion was extended to July 30, 2015.

Summer 2012 Warrants

Pursuant to the terms of our Summer 2012 Offering (see Note 5), during 2012 we issued warrants to purchase up to an aggregate 2,771,671 shares of our common stock to the investors in the Offering. On October 23, 2012, we amended the terms of the Summer 2012 Offering by reducing the exercise price from $0.55 to $0.50 per share. These warrants are set to expire on March 31, 2014 and have an exercise price of $0.50 per share.

Winter 2012 Warrants Extension

      Pursuant to the terms of our Winter 2012 Offering (see Note 5), during 2012 we issued warrants to purchase up to an aggregate 3,127,914 shares of our common stock to the investors in the Offering.

2007 Equity Incentive Plan

On August 7, 2007, and as amended April 29, 2011, our Board of Directors adopted the BioLargo, Inc. 2007 Equity Incentive Plan (“2007 Plan”) as a means of providing our directors, key employees and consultants additional incentive to provide services. Both stock options and stock grants may be made under this plan. The Compensation Committee administers this plan. The plan allows grants of common shares or options to purchase common shares. As plan administrator, the Compensation Committee has sole discretion to set the price of the options. The Compensation Committee may at any time amend or terminate the plan.

On June 17, 2013, we issued an option to purchase 40,000 shares of our common stock to our members of our Board of Directors, pursuant to the terms of the 2007 Equity Plan which calls for an annual automatic issuance. Each board member received an option to purchase 10,000 shares of our common stock, the option vests after a period of one year from the date of grant, expires ten years from the date of issuance, and is exercisable at $0.28 per share, the price of our common stock on the grant date. The fair value of this option totaled $11,200 and was recorded as selling, general and administrative expense.

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model. The following methodology and assumptions were used to calculate share based compensation for the year ended December 31, 2013:

	2012						2013
	Non Plan			2007 Plan			Non Plan			2007 Plan
Risk free interest rate	0.89%	–	1.73%	1.50%	–	2.06%	2.66%	–	3.04%		2.19	%
Expected volatility	483%	–	949%	520%	–	951%	928%	–	951%		928	%
Expected dividend yield		—			—			—			—
Forfeiture rate		—			—			—			—
Expected life in years	4	–	10	7	-	10		10			10

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future.

We recognize compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model. Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

Note 3. Customer Deposit

On March 24, 2011, we entered into a contract in which Central Garden & Pet Company (“Central”) was granted the exclusive worldwide right and license to sell, market, offer for sale, distribute import, export, and otherwise exploit products that contain the BioLargo technologies in the “pet supplies industry” (which is defined in the agreement, and does not include products for equine or livestock). Pursuant to the Central contract, we received a $100,000 non-refundable deposit which would be credited against future orders, if any.  

On February 11, 2013, we gave Central written notice of their failure to purchase the minimum required product from us to maintain exclusive rights to our technology in the “pet supplies industry” pursuant to the agreement. To maintain exclusive rights, within 60 days of our written notice Central must have either purchased the minimum amount of product or compensate us for lost profits as if they had done so.

Central failed to purchase products from us prior to the expiration of the 60-day period, and failed to otherwise compensate us for lost profits. As such, as of April 12, 2013, Central lost its exclusive rights to our technology in the “pet supplies industry”, and we recorded as revenue the $100,000 deposit paid in 2011.

Note 13. Noncontrolling Interest

In May 2012, we formed a subsidiary for the purpose of marketing and selling medical products containing our technology, Clyra Medical Technology, Inc. (“Clyra”). Until December 17, 2012, this subsidiary was wholly owned, with 7,500 shares issued to BioLargo, Inc. On December 17, 2012, Clyra signed executive employment agreements with three individuals, in which each was granted 500 shares of Clyra common stock, one-third of which vested immediately, and the remaining over time. The shares granted to the three executives are restricted from transfer until a sale of the company, whether by means of a sale of its stock or substantially all of its assets, or otherwise by agreement of Clyra, BioLargo and the executives. 

Clyra has also raised $236,000 in net proceeds through issuing 240 shares of its common stock during the year ended December 31, 2013. (see Note 5, “Private Securities Offerings”). The holdings of the executive officers and investors represent18.8% of the issued and outstanding stock of the company.

For the year ended December 31, 2013, there have been no revenues and the financial impact of Clyra’s operations resulted in a net loss of $372,922.
