“Having a clearly defined No filter will pay dividends”
My “No” Filter
I have written previously about creating a strong “No” filter. This enables me to quickly discard opportunities that do not have the characteristics I am looking for. Here is a list of my “No” filters:
- Industry. I have a small list of industries I do not invest in. One of those is construction, there are others. I prefer asset-light businesses which have a higher likelihood of converting earnings to cash flow. If it is in an industry I do not invest in, it is a quick NO. 
- Geography. Is it located somewhere we are willing to operate? Currently, that is the continental US or Panama. If it is not in one of these areas, it goes to the NO pile. 
- Earnings below $2,000,000 EBT. I do not buy anything below this number. Each time we close a deal this number goes up. If it earns less than this amount, it is a NO. 
- Lack of earnings history. How long have they been earning above $1.5m? I do not buy hockey sticks, they are an easy NO. 
- Client concentration. We rarely pursue a company dependent on 2 or 3 clients. We want diversification, a company that is hard to kill. Too high a client concentration is a NO. - These first five I can generally spot on a teaser in less than 15 seconds. This makes for an efficient process. If the opportunity passes the first 5, I move on to some that are not as rigid: 
- Product concentration. If they are selling a product and they do not manufacture it themselves, who manufactures it? Are they dependent on 1 or 2 brands? Again, trying to assess the risk points of the company. If they are reliant on 1 or 2 providers for their business that may be a NO. 
- Is management willing to stay on? In some teasers, they will mention that management is looking to stay on, or there is a well-developed team in place. This one is trickier because if there is no mention of this it does not guarantee they want to leave. Generally, requires a call with the owner. 
This is my NO filter. I built this filter by getting in the reps and looking at thousands of opportunities over the last 13 years.
