 the Company appointed NXC as the exclusive reseller to market, advertise, and resell certain equipment in the U.S. and U.S. territories, the Company expects that NXC will make up a significant portion of revenues in each period in which such NXC Distribution Agreement is in effect. Customer A in the concentration table above is NXC. NXC has executed agreements with other distributors across the U.S. Territories to strengthen its sales channels.

Certain components and services used to manufacture and develop the Company’s products are presently available from only one or a limited number of suppliers or vendors. The Company’s QT Breast Scanner has more than six hundredcomponents, of which less than fivecomponents have such dependencies on limited suppliers or vendors. The loss of any of these suppliers or vendors would potentially require a significant level of hardware and/or software development efforts to incorporate the products or services into the Company’s product.

Net Loss per Share

Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and potentially dilutive common share equivalents outstanding for the period determined using the treasury-stock and if-converted methods. For the purposes of the diluted net loss per share calculation, common stock equivalents are considered to be potentially dilutive securities.
