398 LAWS OF MARYLAND. [CH. 270

(b) Rates shall not discriminate unfairly between risks
involving essentially the same hazards and expense elements.

(c) Due consideration will be given to past and pros-
pective loss experience within and outside the State, reason-
able margin for profit and contingencies, cost of participat-
ing insurance, percentage to be allocated to reserve, operat-
ing expense and all other relevant factors fairly-attributable
to the business of title insurance.

(d) Guarantees may be grouped by classifications for the
establishment of rates and minimum premiums. A special
or unusual guarantee, more hazardous to the insurer than
ordinary title guarantees because of an alleged irregularity
or a difference in interpretation or application of law which
might affect marketability of title, may be classified indi-
vidually and separately according to the circumstances pecu-
liar to each case.

4. (Filing of Rates and Policies, Approval.) (a) Every
insurer must file by December 31, 1947, with the Commis-
sioner, any manual or schedule of rates or premiums which
it proposes to use, together with any rules or regulations
governing the setting or making of such rates or premiums,
and indicate the character or extent of coverage contem-
plated under such rates and premiums, except that insurers
need not include rates or premiums for a special or unusual
guarantee as defined in Section 3 (d) of this sub-title, and
such rates or premiums may be classified individually and
separately according to the circumstances peculiar to each
case.

(b) Every insurer must file by December 31, 1947, with the
Commissioner, all forms of contracts, policies or guarantees
of insurance with any and all types of modifications thereof,
except as to special or unusual risks, which it proposes to
use.

(c) After January 1, 1948, no change in rates or premiums
or in the forms of contracts, policies or guarantees of in-
surance shall be permitted to any insurer, unless and until
a report indicating such change shall be filed and approved
by the Commissioner.

(d) Any filing made pursuant to this section shall be
approved by the Commissioner, unless he finds that such
filing does not meet the requirements of this sub-title or
shall otherwise be contrary to law. As soon as reasonably
possible after the filing has been made, the Commissioner
shall, in writing, approve or disapprove the same; provided
