- We expect our gross margin to fluctuate over time, depending on the factors described above.
- We expect our research and development expenses to increase in absolute dollars as we continue to invest in research and development in order to expand the capabilities of our cloud networking platform, introduce new products and features, and continue to invest in our technology.
- We expect our sales and marketing expenses to increase in absolute dollars as we continue to expand our sales and marketing efforts worldwide.
- We plan to continue to invest for long-term growth.

- Our material cash requirements represent material expected or contractually committed future payment obligations.
- We believe that we will be able to fund these obligations through cash generated from operations and from our existing balances of cash, cash equivalents and marketable securities.
