Virginia needed its infrastructure rebuilt to restore its economic base, especially to get crops and manufactured goods to market. Accordingly, the Virginia General Assembly allowed reclassification of its first mortgages on existing rail lines to second mortgages, so that the railroads could get money from first mortgages to rebuild. Executive officials also allowed corporations to self-assess for other tax purposes, which meant corporate taxes were very low. However, the state still needed money to pay the debt as well as to operate the government and particularly public schools (theoretically possible since the days of Thomas Jefferson but only required by the state constitution since 1870). The Funding Act also contained a provision allowing coupons to be used at full value to pay taxes, which cut state revenues significantly (as the bonds were usually discounted significantly). In 1872, the General Assembly reduced the interest rate to 4%, but debt interest still constituted more than half of government expenditures, and the state ran a significant deficit. By the end of the decade, the state auditor was paying the bond debt, but not debts owed to teachers or to localities which had built public schools.
