As part of the monitoring process, our Investment Adviser has developed risk policies pursuant to which it regularly assesses the risk profile of each of our debt investments and rates each of them based on the following categories, which we refer to as “Internal Risk Ratings”:

Internal Risk Ratings Definitions

Rating	Definition
1	Performing—Low Risk: Borrower is operating more than 10% ahead of the base case.
2	Performing—Stable Risk: Borrower is operating within 10% of the base case (above or below). This is the initial rating assigned to all new borrowers.
3	Performing—Management Notice: Borrower is operating more than 10% below the base case. A financial covenant default may have occurred, but there is a low risk of payment default.
4	Watch List: Borrower is operating more than 20% below the base case and there is a high risk of covenant default, or it may have already occurred. Payments are current although subject to greater uncertainty, and there is moderate to high risk of payment default.
5	Watch List—Possible Loss: Borrower is operating more than 30% below the base case. At the current level of operations and financial condition, the borrower does not have the ability to service and ultimately repay or refinance all outstanding debt on current terms. Payment default is very likely or may have occurred. Loss of principal is possible.
6	Watch List—Probable Loss: Borrower is operating more than 40% below the base case, and at the current level of operations and financial condition, the borrower does not have the ability to service and ultimately repay or refinance all outstanding debt on current terms. Payment default is very likely or may have already occurred. Additionally, the prospects for improvement in the borrower’s situation are sufficiently negative that impairment of some or all principal is probable.

Our Investment Adviser’s risk rating model is based on evaluating portfolio company performance in comparison to the base case when considering certain credit metrics including, but not limited to, adjusted EBITDA and net senior leverage as well as specific events including, but not limited to, default and impairment.

Our Investment Adviser monitors and, when appropriate, changes the investment ratings assigned to each debt investment in our portfolio. In connection with our quarterly valuation process, our Investment Adviser reviews our investment ratings on a regular basis. The following table summarizes the Internal Risk Ratings of our debt portfolio as of March 31, 2019 and December 31, 2018:

	March 31, 2019				December 31, 2018
	Fair Value		% of Fair Value		Fair Value		% of Fair Value
(dollar amounts in millions)
Internal Risk Rating 1	$	70.8	3.74	%	$	71.0	4.12	%
Internal Risk Rating 2	1,381.7		73.02		1,302.9		75.52
Internal Risk Rating 3	212.5		11.23		208.4		12.08
Internal Risk Rating 4	189.2		10.00		105.1		6.09
Internal Risk Rating 5	23.3		1.23		23.5		1.36
Internal Risk Rating 6	14.7		0.78		14.3		0.83
Total	$	1,892.2	100.00	%	$	1,725.2	100.00	%

As of March 31, 2019 and December 31, 2018, the weighted average Internal Risk Rating of our debt investment portfolio was 2.3.

Consolidated Results of Operations

(dollar amounts in thousands, except per share data)

Total investment income for the three month periods ended March 31, 2019 and December 31, 2018 was $55,187 and $56,311, respectively. This $1,124 net decrease during the three month period ended March 31, 2019 compared to the three month period ended December 31, 2018 was primarily due to a decrease in income recognized from the acceleration of OID and prepayment fees from reduced prepayments, partially offset by an increase in interest income from growth in the investment portfolio.

Total expenses for the three month periods ended March 31, 2019 and December 31, 2018 were $27,625 and $26,900, respectively. This $725 net increase during the three month period ended March 31, 2019 compared to the three month period ended December 31, 2018 was primarily attributable to an increase in interest expense as a result of an increase in average borrowings and LIBOR, partially offset by a decrease in incentive fees.

During the three month period ended March 31, 2019, the Company recorded a net realized gain and change in unrealized appreciation of $6,164. This was primarily driven by a decrease in market yields.

Liquidity and Capital Resources

(dollar amounts in thousands, except per share data)

As of March 31, 2019, the Company had cash and cash equivalents of $40,071, notes payable (before debt issuance costs) of $449,200, and secured borrowings outstanding of $660,959. As of March 31, 2019, the Company had $252,041 of remaining unfunded commitments and $109,420 available for additional borrowings under its revolving credit facilities, subject to leverage and borrowing base restrictions.

Dividend

On May 6, 2019, our Board of Directors declared a quarterly dividend of $0.37 per share, which is payable on July 17, 2019 to stockholders of record as of June 28, 2019.
