Note 13. Commitments, Contingencies and Subsequent Events Financial Condition and Liquidity As described in Note 7   Current Liabilities and Debt Obligations, we maintain a revolving Facility with Wells Fargo. Borrowings under the Facility are collateralized by substantially all of our assets including inventory, equipment, and accounts receivable. The amount of available borrowings fluctuates based on the underlying asset-borrowing base, in general 85% of our trade accounts receivable, as adjusted by certain reserves (as further defined in the Facility agreement). The Facility provides us with virtually all of the liquidity we require to meet our operating, investing and financing needs. Therefore, maintaining sufficient availability on the Facility is the most critical factor in our liquidity. While a variety of factors related to sources and uses of cash, such as timeliness of accounts receivable collections, vendor credit terms, or significant collateral requirements, ultimately impact our liquidity, such factors may or may not have a direct impact on our liquidity, based on how the transactions associated with such circumstances impact our availability under the Facility. For example, a contractual requirement to post collateral for a duration of several months, depending on the materiality of the amount, could have an immediate negative effect on our liquidity, as such a circumstance would utilize availability on the Facility without a near-term cash inflow back to us. Likewise, the release of such collateral could have a corresponding positive effect on our liquidity, as it would represent an addition to our availability without any corresponding near-term cash outflow. Similarly, a slow-down of payments from a customer, group of customers or government payment office would not have an immediate and direct effect on our availability on the Facility unless the slowdown was material in amount and over an extended period of time. Any of these examples would have an impact on the Facility, and therefore our li
