Revenue Recognition In May 2014, the Financial Accounting Standards Board (which we refer to as the FASB) issued ASU 2014-19, Revenue from Contracts with Customers (ASU 2014-19). ASU 2014-19 established a single revenue recognition model for all contracts with customers, eliminates industry specific requirements and expands disclosure requirements. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core principle, an entity should apply the following five steps: (1) identify contracts with customers, (2) identify the performance obligations in the contracts, (3) determine the transaction price, (4) allocate the transaction price to the performance obligation in the contract, and (5) recognize revenue as the entity satisfies performance obligations. Effective July 1, 2018, we adopted ASU 2014-19 using the modified retrospective method. The adoption of ASU 2014-19 did not have an impact on our consolidated financial statements but required enhanced footnote disclosures. See Note 3, Revenue Recognition, for additional information. We derive revenue from several types of activities  medical device sales, branded generic pharmaceutical sales, commercial real estate leasing and financial services. Our medical device sales include the marketing and distribution of certain professional and consumer grade digital non-contact thermometers, needle destruction unit, advanced bleeding control, non-compression hemostasis, and personal protection equipment. Through our United Kingdom based subsidiary, we manufacture, and market, branded generic pharmaceuticals, and certain other generic pharmaceuticals known as specials. Our real estate leasing revenues are from certain commercial properties under lease. The financial service revenue is from brokerage services. The Company offers customer discounts in certain cases. Such discounts are estimated at time of product sale and revenues are reduced for such discounts at the time of the sale. Shipping and handling costs are included in revenue and costs of goods sold.
