The U.S. economy grew in the first quarter — but very slowly. Most economy watchers blame the frigid winter weather for dampening forward progress. The Conference Board Consumer Confidence Index, which had increased in March, declined slightly in April. The Index now stands at 82.3, down from 83.9 in March. The Conference Board said its leading economic index rose by 0.8 percent in March after climbing by 0.5 percent in February, the third consecutive monthly increase. The increase was broad-based, and labor market indicators and the interest rate spread largely drove the March increase, offsetting the negative contribution from building permits. The Institute for Supply Management reported that U.S. manufacturing grew faster in April than in March as exports picked up and factories accelerated hiring. The manufacturing index rose to 54.9 from 53.7 in March, with a reading above 50 indicating expansion. In April, total nonfarm payroll employment rose by 288,000, and the unemployment rate fell by 0.4 percentage point to 6.3 percent. Employment gains were reported to be widespread, led by job growth in professional and business services, retail trade, food services, and construction.

First Quarter 2014 Operating Results As forecasted, known tenant move outs during the quarter led to lower occupancy, and coupled with the higher than normal utility costs from the harsh winter, had a noticeable impact on our first quarter operating results.
