The U.S. Supreme Court held that an insider's failure to file a disclosure report under Section 16(a) of the Securities Exchange Act of 1934, as amended, does not toll the two-year statute of limitations for claims seeking recovery of "short-swing" profits under Section 16(b) of such Act.  Under Section 16(b), profits realized by insiders (i.e., 10% shareholders of public companies) from the purchase and sale (or sale and purchase) of a public company's equity securities within a 6-month period are subject to disgorgement.  The court found that the two-year statute of limitations began to run at the time the profit was realized.
