Comcast subscribers can't watch HBO Go on PlayStation 4. The app arrived on Sony's console Tuesday â and let me tell you, PlayStation owners had been dreaming of and awaiting that day for months.And then it came!nd this isn't the first time Sony and Comcast have butted heads.

Weighted Average Expense Ratio. Because net expense ratios are usually weighted the same for both small and large funds, they are calculated using a simple formula based only on overall expenses as a percentage of net assets.
A fund's expense ratio has a direct effect on the return to investors. If a fund portfolio earns 10 percent and the fund's expense ratio is 1 percent, the investors will realize a 9 percent return from their mutual fund shares. The average expense ratio for the different types of mutual funds can help investors evaluate the expenses of their own mutual fund investments.
