the federal law to buy and sell human tissues, the company utilizes deferred preservation costs to account for the human tissues held in quarantine or processing within the organization. In 2014, the deferred preservation costs totaled $540,000 in write-downs. Write-downs for deferred preservation costs are calculated by the costs related to acquiring the transplantable tissue, including direct materials and labor utilized as well as indirect cost, at lower than market value.
In the past, Cryolife had been cited by the FDA because of quality, validation, environmental monitoring, handling, processing, and employee training issues. Revenues from the preservation area of the company suffered an overall 4% decline in revenues in order to address the issues that the FDA referred to in the warning letters from 2012, 2013, and 2014. Management decided to conduct additional internal employee training the second quarter of 2014 by halting preservation services in order to meet the requirements of the observations of the FDA. Cryolife continues to improve areas cited in the FDA warning letters in order to remain compliant with the regulations.
