Many investments, which have a horizon of one year or more, are considered a long-term investment for tax purposes. Long-term investments are investments made by a company in order to secure an additional income stream or a strategic goal. Such investments can range from anything from buying a minority stake at another company to long-run hedges against oil prices. Berkshire Hathaway 's investment in Coca-Cola and Southwest Airlines' hedge against high oil prices are good examples of long-term investments.
In this case too, the company needs to exercise prudence in reporting the value of the investment. They are reported at the lower of purchase price or market value. Any gains from these investments are only recorded after the sale of the position. These gains are subject to capital gains taxes rather than income taxes.
Futures transactions are long term if the contract was held for more than 6 months. In futures trading, 60% of your capital gain or loss will be treated as a long-term capital gain or loss, and 40% will be treated as a short-term capital gain or loss regardless of how long you actually held the property. Any capital gain or loss on a sale, of "Securities," Futures Contracts will be considered short term, regardless of how long you hold the contract. 
Long-term investments are to be held for many years and are not intended to be disposed of in the near future.  Mark Mobius seeks long-term capital appreciation, looking at the company’s potential for earnings and growth over a five-year horizon. His funds are value-oriented, long-term, buy-and-hold vehicles in line with the Templeton investment philosophy.  Warren Buffett’s favorite holding period is forever.
