c. Revenue Recognition - Product Revenues ? Specialty Pharmacy ? Our specialty pharmacy revenue is not recognized until the patient receives the filled prescription. Typically, we prepare and fill a prescription that has been approved by an insurance provider, ship the filled prescription to the patient, and upon confirmation of receipt of the prescription by the patient, we recognize revenue. Any prescription in which the patient has not received product, but we may have been reimbursed by the insurance provider, is recorded as deferred revenue or accounts receivable reserved, for future deductions. Occasionally, a patient may return the product or the product was not deliverable, in such cases the revenue related to the prescription is reversed. If we received payment from a third-party payor for undelivered product, we record an allowance for deductions to be applied to future reimbursements due from the third-part payors. As of December 31, 2014 and 2013, we had no deferred revenue, but we did have an allowance for future deductions of $589,415 reserved against accounts receivable at December 31, 2014. Due to the nature of the industry and the reimbursement environment in which we operate, certain estimates are required in order to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they may have to be revised or updated as additional information becomes available. It is possible that management?s estimates could change, which could have an impact on operations and cash flows. Specifically, the complexity of many billing arrangements and the uncertainty of reimbursement amounts for certain services from certain third-party payors may result in adjustments to amounts originally recorded. As of December 31, 2014, $1,302,441 has been recorded as a reserve for third-party payors deductions and chargebacks. We believe we have adequate allowances for contractual adjustments relating to all known third-party payors disputes. However, no assurance c
