Maya Export Import Nurbs with periodic form issue

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Create Nurbs surface with span greater than 8 and UV range from 0-1 with a 
Periodic form
2.Export the alembic
3.Import back the alembic to maya now the Form is Open

What version of the product are you using? On what operating system?
1.5, linux

Please provide any additional information below.
if the spans is under "8" it will do the correct things.
if is not under 8, the min max range UV needed to be 0 to spans cant not be 0-1.
otherwise the form will flip to open instead of periodic or close.
just wondering is this actually an expected behavior?
