| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance During the above dates, Berkshire Hathaway Inc Class B contributed 2.58% to the Fund and had the largest positive impact. Berkshire's investment in Apple, the fact that it reduced its share count materially, and continued economic strength filtering down to its many operating companies lead to this outperformance. United Therapeutics Corporation contributed 2.31% to the Fund and had the second largest positive impact. Over the course of the year, market participants realized the position that United Therapeutics maintained in their lines of business was still that of market leader. That occurred precisely at a time where new markets and products were showing demonstrable and durable growth for them. Lastly, Paypal Holdings contributed 1.43% and had the third largest positive impact. We started allocating capital to Paypal at a time when the stock was severely out of favor, but had, what we deemed, very strong products with decent moats. This year's strong performance was due to these products largely getting a refresh, which we believe has entered the stock into the early innings of a turnaround. During the above stated dates, Pinterest Inc. contributed a -0.88% return to the Fund. We believe the general reason for Pinterest stock becoming cheaper has mostly been due to the fact that large cap leaders in their space have been given the benefit of the doubt, while anyone that isn't growing at the same rate that hasn't completely demonstrated their staying power, has been suffering. Pinterest's clients don't get as many "eyeballs" as Facebook or Instagram and even though Pinterest is growing, we think that was largely its biggest headwind. Cleveland Cliffs has suffered for many reasons. First and foremost iron ore prices have not held up to the degree that we thought they would and that has been a massive headwind. They've also suffered to a larger degree than other steel stocks as they are considerably more reliant on automotive stocks, where they may also be losing market share. WEX Inc. was the third largest detractor during the time period as their growth rates have moderated more than some of their competitors. |
