Commitments and Contingencies
Commitments and Contingencies	14 — Commitments and Contingencies Purchase commitments. We had various purchase orders for goods or services totaling approximately $3,208,174 at December 31, 2019. No amounts related to these purchase orders have been recognized in our balance sheet. Indemnifications. Under our amended and restated bylaws, we have agreed to indemnify our officers and directors for certain events or occurrences arising as a result of the officer or director serving in such capacity. We have a director and officer liability insurance policy that limits our exposure under these indemnifications and enables us to recover a portion of any future loss arising out of them. In addition, in the normal course of business, we enter into contracts that contain indemnification clauses whereby the Company indemnifies our customers against damages associated with product failures. We have determined that these agreements fall within the scope of ASC 460, Guarantees. We have obtained liability insurance providing coverage that limits our exposure for these indemnified matters. We have not incurred costs to defend lawsuits or settle claims related to these indemnities. We believe the estimated fair value of these indemnities is minimal and have not recorded a liability for these agreements as of December 31, 2019. Legal matters. We may from time to time become a party to various legal proceedings or claims that arise in the ordinary course of business.
