Income Taxes [Abstract]
Income Taxes	10.    INCOME TAXES The provision for income taxes for the interim period is based on an estimate of the annual effective tax rate adjusted to reflect the impact of discrete items. Management judgment is required in projecting ordinary income to estimate the Company’s annual effective tax rate. The effective tax rate related to controlling interest was 36% and 39% for the three and nine months ended October 29, 2017,  respectively, and 40% and 39% for the three and nine months ended October 30, 2016, respectively. The income from SRV was excluded from the calculation of the Company’s effective tax rate, as SRV is an “S” corporation and not subject to income taxes.
