20 Pa.C.S. § 7315.1: Retention of cash; temporary investments.

(a) Uninvested cash.--A fiduciary may hold cash uninvested:

(1) which he reasonably expects to:

(i) distribute to beneficiaries as income on a quarterly or more frequent basis;

(ii) use for payment of debts, taxes, expenses of administration or reinvestment within the next 90 days; or

(2) when the amount available for investment does not justify the administrative burden of making the investment determined in the light of the facilities available to the fiduciary.

A corporate fiduciary may deposit uninvested funds in its own commercial department.

(b) Temporary investments.--A fiduciary may make temporary investment of funds which he is entitled to hold uninvested or which he wishes to hold in liquid form in short-term interest-bearing obligations or deposits, or other short-term liquid investments, selected in each case in compliance with the standards of section 7302(b) (relating to authorized investments; in general), but without regard to any investment restrictions imposed by the governing instrument and may make a reasonable charge, in addition to all other compensation to which he is entitled, for services rendered in making the temporary investment.
