We keep track of the most material factors impacting each of our portfolio companies. We believe aspects of governance are critical to any investment, for example, compensation and the structure of decision making at the board level. We have asked all of our companies about human capital management and other factors typically classifiied as social. We have standard metrics that we look at like turnover, but also ask about company specific factors as appropriate, for example, looking at how companies recruit and retain certian types of vital personnel. We do analyze our companies for enviromental factors, but many of them have relatively low tangible asset bases which makes their environmental risk factors relatively smaller versus the total universe of public companies.
