Factors such as geographical mix, delivery terms and timeline(s), product mix, related services mix and other deal terms may differ significantly from our expectations, and thus impact our revenue recognition timing, gross margins, costs and expenses, as well as cash flow from operations. In addition, the spending decisions of our customers throughout the year may also create unpredictable fluctuations in the timing in which we receive orders and can recognize revenues, which may impact our quarterly results. Such unpredictable fluctuations could be material in cases where these spending decisions are made by our largest customers or regarding significant deals. In addition, the quarterly variation of our operating results may in turn create volatility in the market price for our shares.
We believe that current working capital, cash and cash equivalent balances together with the Credit Facility available with the four financial institutions, will be sufficient for our expected requirements through at least the next 12 months.
