Give you a statement and table with its title in Markdown format, please determine whether the statement is supported or refuted by, or is unrelated to the table. It'a binary classification problem, you should choose the answer between supported and refuted. Table cells in one row are seperated by '|', and different rows are seperated by '
'.

Table:
| fourcc | dx 10 name | description | alpha premultiplied | compression ratio | texture type |
| dxt1 | bc1 | 1 - bit alpha / opaque | n / a | 6:1 (for 24 bit source image) | simple non - alpha |
| dxt2 | (none) | explicit alpha | yes | 4:1 | sharp alpha |
| dxt3 | bc2 | explicit alpha | no | 4:1 | sharp alpha |
| dxt4 | (none) | interpolated alpha | yes | 4:1 | gradient alpha |
| dxt5 | bc3 | interpolated alpha | no | 4:1 | gradient alpha |
Title:
none
Statement:
the dx - 10 bc2 does not have a premultiplied alpha and it is described as having explicit alpha
Answer:
supported
