The accompanying unaudited interim financial statements of Nanophase Technologies Corporation (“Nanophase” or the “Company”, including “we”, “our” or “us”) reflect all adjustments (consisting of normal recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the financial position and operating results of the Company for the interim periods presented. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. | |
These financial statements should be read in conjunction with our audited financial statements and notes thereto for the year ended December 31, 2013, included in our Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the Securities and Exchange Commission. |

Description of Business | ' |
(2) Description of Business | |
Nanophase is a nanomaterials and applications developer and commercial manufacturer with an integrated family of nanomaterial and related technologies. We produce engineered nano and sub-micron materials for use in a variety of diverse existing and developing markets: personal care including sunscreens, architectural coatings, industrial coating applications, abrasion-resistant additives, plastics additives, medical diagnostics, energy and a variety of surface finishing technologies (polishing) applications. We target markets in which we believe practical solutions may be found using our products. We work closely with current and potential customers in these target markets to identify their material and performance requirements and market our materials to various end-use applications manufacturers. Recently developed technologies have made certain new products possible and opened potential new markets. Although our primary strategic focus has been the North American market, we currently sell material to customers overseas and have been working to expand our reach in foreign markets. | |
The Company was incorporated in Illinois on November 25, 1989, and became a Delaware corporation in November 1997. Our common stock trades on the OTCQB marketplace under the symbol NANX. | |
While product sales comprise the majority of our revenue, we also recognize revenue from other sources from time to time. These activities are not expected to drive the long-term growth of the business. For this reason we classify such revenue as “other revenue” in our Statement of Operations, as it does not represent revenue directly from our nanocrystalline materials. | |
The presentation of certain prior year disclosures has been modified to conform to current year presentation, as financial data is now presented in thousands of dollars rather than in dollars. |

We follow the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. | |
Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable and accrued expenses. The fair values of all financial instruments were not materially different from their carrying values. |

We follow FASB ASC Topic 718, Share-Based Payments, in which compensation expense is recognized only for share-based payments expected to vest. We recognized compensation expense related to stock options of $53 and $111 for the three and six month periods ended June 30, 2014, respectively, compared to $70 and $139 for the same periods in 2013. | |||||
As of June 30, 2014, there was approximately $349 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under our stock option plans. That cost is expected to be recognized over a remaining weighted-average period of 2.2 years. | |||||
Stock Options and Stock Grants | |||||
During the six months ended June 30, 2014, no stock options were exercised. During the six months ended June 30, 2013, 10,000 shares were issued pursuant to stock option exercises with proceeds of $3 realized. During the six months ended June 30, 2014, 568,000 stock options were granted compared to 553,000 for the same period in 2013. During the six months ended June 30, 2014, 22,000 stock options were forfeited compared to 91,133 stock options forfeited during the same period in 2013. | |||||
Stock Appreciation Rights | |||||
Prior to 2011, we granted outside directors stock appreciation rights (SARs). The change in fair value of the awards granted during prior years is included in non-cash compensation expense for the three and six months ended June 30, 2014 and 2013. The SARs granted vested immediately and are payable upon the directors’ removal or resignation from the position of director. These awards are accounted for as liability awards, included in accrued expenses as of June 30, 2014 and 2013, and adjusted to fair value each reporting period. The fair value of the liability on June 30, 2014 was $4 compared to $8 on December 31, 2013. | |||||
As of June 30, 2014, we did not have any unvested restricted stock or performance shares outstanding. | |||||

(7) Significant Customers and Contingencies | |
Sales to three customers constituted approximately 68%, 10% and 6%, respectively, of our total revenue for the three months ended June 30, 2014, and 74%, 5% and 6%, respectively, of our total revenue for the six months ended June 30, 2014. Amounts included in accounts receivable on June 30, 2014 relating to these three customers were approximately $632, $0 and $171, respectively. Revenue from these three customers constituted approximately 62%, 11% and 9%, respectively, of the Company’s total revenue for the three months ended June 30, 2013 and 71%, 5% and 8%, respectively, for the six months ended June 30, 2013. Amounts included in accounts receivable on June 30, 2013 relating to these three customers were approximately $845, $284 and $243, respectively. The loss of one of these significant customers or the failure to attract new customers could have a material adverse effect on our business, results of operations and financial condition. | |
We currently have exclusive supply agreements with BASF Corporation (“BASF”), our largest customer, that have contingencies outlined which could potentially result in the license of technology and/or the sale of production equipment from the Company to the customer intended to provide capacity sufficient to meet the customer’s production needs. This outcome may occur if we fail to meet certain performance requirements, certain other obligations and/or certain financial covenants. The most restrictive financial covenants in one of our supply agreements with BASF “trigger” a technology transfer right (license and equipment sale at BASF’s option) in the event (a) that earnings of the twelve month period ending with our most recently published quarterly financial statements are less than zero and our cash, cash equivalents and certain investments are less than $1 million, or (b) of an acceleration of any debt maturity having a principal amount of more than $10 million. Our supply agreements with BASF also “trigger” a technology transfer right in the event of our insolvency, as further defined within the agreements. In the event of an equipment sale, upon incurring a triggering event, the equipment would be sold to the customer at either 115% of the equipment’s net book value or the greater of 30% of the original book value of such equipment, and any associated upgrades to it, or 115% of the equipment’s net book value, depending on the contract and related equipment. | |
We believe that we have sufficient cash (See Liquidity and Capital Resources in Management’s Discussion and Analysis in Part I, Item 2 of this Form 10-Q for a further discussion) to operate our business throughout 2014. If a triggering event were to occur and BASF elected to proceed with the license and related equipment sale mentioned above, we would receive royalty payments from this customer for products sold using our technology; however, we would lose both significant revenue and the ability to generate significant revenue to replace that which was lost in the near term. Replacement of necessary equipment that could be purchased and removed by the customer pursuant to this triggering event could take in excess of twelve months. Any additional capital outlays required to rebuild capacity would probably be greater than the proceeds from the purchase of the assets as dictated by our agreement with the customer. Similar consequences would occur if we were determined to have materially breached certain other provisions of the supply agreement with BASF. Any such event would also likely result in the loss of many of our key staff and line employees due to economic realities. We believe that our employees are a critical component of our success and could be difficult to replace them quickly. Given the occurrence of any such event, we might not be able to hire and retain skilled employees given the stigma relating to such an event and its impact on us. Finally, any shortfall in capital needed to operate the business as management intends, including with respect to avoiding this triggering event as described above, may result in a curtailment of certain activities or anticipated investments. |
