HP Bank marketed TPixel notes' under the exemption for debentures which are sold with a minimum consideration of $500,000. F our months after purchasing the Pixel notes from HP Bank, Loretta and Patrick are dissatisfied with their investment. They discover that the disclosed information relating to the 'Pixel notes' were prepared under the accounting standards of the British Virgin Islands; transactions with certain special purpose vehicles were treated as off-balance sheet, and not accounted for in the same manner as under Hong Kong accounting rules. There was no reconciliation of the disparate accounting treatment in the information memorandum circulated to the investors in Pixel notes. They seek  advice whether they have any rights to sue under the common law or under statute
