Liquidity and Capital Resources
Our primary liquidity needs include interest and principal repayments under the Capital One Revolving Financing, interest payments on the 2026 Notes, our unfunded loan commitments (if any), investments in portfolio companies, dividend distributions to our stockholders and operating expenses. We believe that our current cash on hand and our anticipated cash flows from operations, including from contractual monthly portfolio company payments and prepayments, will be adequate to meet our cash needs for our daily operations.
