Clothing retailer Abercrombie & Fitch enjoyed phenomenal success in the late $1990$s. Between $1996$ and $2000$, its sales grew almost fourfold-from $\$ 335$ million to more than $\$ 1.2$ billion-and its stock price soared by more than $500 \%$. However, in $2002$, its growth rate had begun to slow down, and Abercrombie had a hard time meeting its quarterly earnings targets. As a result, the stock price in late $2002$ was about half of what it was $3$ years earlier. Abercrombie's struggles resulted from increased competition, a sluggish economy, and the challenges of staying ahead of the fashion curve. From late $2002$ until November $2007$, the company's stock rebounded strongly; however, its stock price declined during the $2008$ economic downturn. Its stock price rebounded until late October $2011$, when it began a downward trend again. Its stock price started to rise again in early $2013$, but has been on a downward trend since that time. Questions remain about the firm's long-term growth prospects. However, the company has been cutting costs and improving productivity with its focus on the supply chain. In addition, it has been actively repurchasing shares, indicating that management believes its shares are undervalued. The company continues to steadily expand stores abroad while closing underperforming domestic stores.

Given the questions about Abercrombie's future growth rate, analysts have focused on the company's earnings reports. Financial websites such as Yahoo! Finance, Morningstar, and MSN Money provide information on the company's recent earnings history along with a summary of analysts' earnings forecasts.

Based on analysts' forecasts, what is the expected long-term ($5$-year) growth rate in earnings?
