Hmmm...looks like this one might be different afterall. The EX-IM bank started a pilot program in March of last year for small business lines of credit:
However, I'm not sure how much they actually have available under the line since it's capped based on a % of their exports from the previous year, or a % of their net current assets as of their last financial statements.
Seeing as how their net current assets are negative, they wouldn't have any funds available under the facility currently unless they're somehow discounting the current portion of related notes payable. If that's the case then they'd be capped by 50% of their exports from 2012, which would mean roughly $250K would be available. Hopefully they'll disclose the details in their next quarterly report.
