- I have a question about the average basis method for mutual
- funds. The question is basically this:
- After a sale, how is the new average basis computed?
-
- According to the relevant IRS pubs, average basis is defined
- as the total adjusted basis divided by the number of shares.
- They also say that FIFO is used -- the first shares acquired are
- deemed to have been disposed of first.
-
- Ok...now for an example illustrating my question...
-
- bought 100 shares at $10
- bought 100 shares at $1
-
- total adj basis = 100*$10 + 100*$1 = $1100
- total shares = 200
- avg basis = $5.50
-
- I now sell 100 shares. Using FIFO, I have a 100($10-$5.50)= $450
- loss.
-
- Now the tricky part...what is the new average basis?
- This comes down to what is the total adjusted basis.
- The remaining shares were all acquired for $1,
- so looking at it that way, total adjusted basis = $100, so
- avg basis = $1 at this point.
- Or, does the IRS hold that the previous average basis
- becomes the new basis, i.e. when the average basis of $5.50
- was computed, this "replaced" the actual basis, and thus
- the total adjusted basis would be 100*5.50 = $550, for an
- average basis of $5.50. The various IRS publications
- are very ambiguous on this -- the examples they give never
- show how to recompute avg basis after a sale.
-
- Anyone have a definitive answer on this?
