Risks and Uncertainties [Abstract]  

Financial instruments that potentially subject us to a concentration of credit risk consist of cash and cash equivalents and accounts receivable.

As of March 31, 2020, and 2019, we maintained our cash and cash equivalents primarily with major U.S. financial institutions and foreign banks. Deposits with these institutions at times exceeded the federally insured limits, which potentially subjects us to concentration of credit risk. We have not historically experienced any losses related to these balances and believe that there is minimal risk of any such losses.

As of March 31, 2020, approximately $4.8 million of our total cash and cash equivalents of $54.2 million was held by our foreign subsidiaries. If we repatriate these funds for use in our U.S. operations, we may be required to pay income taxes in the U.S. on the repatriated amount at the tax rates then in effect, reducing the net cash proceeds to us after repatriation. In the event we elect to repatriate any of these funds, we believe we have sufficient net operating losses for the foreseeable future to offset any repatriated income. As a result, we do not expect that any such repatriation would create a tax liability in the U.S. or have a material impact on our effective tax rate.

Customer Concentration
A substantial portion of our revenue is generated through arrangements with Southwest Airlines, Inc. (“Southwest Airlines”). As of March 31, 2020 and 2019, the percentage of revenue generated through this customer was as follows:
Three Months Ended March 31,

Southwest Airlines as a percentage of Connectivity revenue

No other customer accounted for greater than 10% of total revenue for the periods presented. Accounts receivable from Southwest Airlines represented 16% and 17% of the total accounts receivable as of each of March 31, 2020 and December 31, 2019, respectively.
