We maintain cash and cash equivalents with various financial institutions located in different geographical regions, and our policy is designed to limit exposure to any individual counterparty. As part of our risk management processes, we perform periodic evaluations of the relative credit standing of the financial institutions.

The current expected credit loss model is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect collectability. Current expected credit losses, and subsequent adjustments, represent an estimate of lifetime expected credit losses that are recorded as an allowance deducted from the amortized cost of the financial instrument. The updated guidance is effective for the Company beginning on January 1, 2020 and will be adopted using a modified retrospective transition approach. We do not expect the adoption to have a material impact on our financial statements.</span></div>
