| revisions to Articles 8 and 9, Article 9 did not permit |
| perfection of security interests in securities by filing. |
| Accordingly, parties who deal in securities never developed a |
| practice of searching the UCC files before conducting securities |
| transactions. Although filing is now a permissible method of |
| perfection, in order to avoid disruption of existing practices in |
| this business it is necessary to give perfection by filing a |
| different and more limited effect for securities than for some |
| other forms of collateral. The priority rules are not based on |
| the assumption that parties who perfect by the usual method of |
| obtaining control will search the files. Quite the contrary, the |
| control priority rule is intended to ensure that, with respect to |
| investment property, secured parties who do obtain control are |
| entirely unaffected by filings. To state the point another way, |
| perfection by filing is intended to affect only general creditors |
| or other secured creditors who rely on filing. The rule that a |
| security interest perfected by filing can be primed by a control |
| security interest, without regard to awareness, is a consequence |
| of the system of perfection and priority rules for investment |
| property. These rules are designed to take account of the |
| circumstances of the securities markets, where filing is not |
| given the same effect as for some other forms of property. No |
| implication is made about the effect of filing with respect to |
| security interests in other forms of property, nor about other |
| Article 9 [Maine cite Article 9-A] rules, e.g., Section 9330 |
| [Maine cite section 9-1330], which govern the circumstances in |
| which security interests in other forms of property perfected by |
| filing can be primed by subsequent perfected security interests. |
