It’s the dirty little secret many shampoo companies don’t want you to know.  When you wash your hair with certain traditional chemical shampoos, you may actually be removing your hair and scalp（头皮）of their natural oils.  These shampoos generate a thick bubble to clean hair, they can also create dryness, curl, dullness, and color fade. We then spend a lot of time and money on products that are effectively repairing the damage caused by shampoo.

Chaz Dean got tired of clients leaving his salon raving about their color and the feeling of their hair---brassy（似黄铜的） and dull. He knew the main cause was likely their shampoo, so he started experimenting with various ingredients, including natural herbs and botanicals, that he knew had cleansing（弄干净）and hydrating (保湿的) properties.

The result was a totally new approach to the way we cleanse our hair.  It’s called WEN® Cleansing Conditioner.  WEN® contains a super-hydrating natural herbs and botanicals mixture of glycerin, chamomile(甘菊), rosemary, calendula, and Cherry bark, which when combined, will both cleanse the hair as well as give shine and softness, even to damaged hair.

WEN® is a 5-in-1 formula（配方） that takes the place of your shampoo, And the most amazing thing about it is that it cleanses without bubble.  Instead, when mixed with water, it creates a smooth bubble for shiny, healthy-looking, manageable results.  The first time you try it certainly feels strange, but the results speak for themselves.

Before being marketed, WEN® went through extensive consumer tests, and the results were impressive.  More than 90 percent of the participants in the studies reported that their hair was more shiny, less frizzy, and had more bounce.

WEN® is recommended for all hair types, and once you start using it, it will become the only cleanser/conditioner you will want to include in your daily routine.

Right now, WEN® is offering an easy way for online shoppers to try the product.  Now you just pay less than $30 and have a 60 day money back guarantee if you are not completely satisfied. Click here to learn more about WEN® and try this revolutionary new approach yourself.

甲公司为一家上市公司(增值税一般纳税人)，2000年实现的利润总额为12500000元。该公司在1998年及以前年度适用的所得税税率为30%，1999年起所得税税率调整为33%。该公司的所得税核算采用债务法，由于时间性差异生产的递延税款预计均可以转回。
甲公司2000年度涉及所得税方面的有关资料如下：
(1)长期股权投资有两项：①1999年12月对乙公司的投资占该公司40%的股份，2000年度乙公司实现净利润5000000元(乙公司的所得税税率为20%)，2000年度乙公司未宣告分配利润。
②1999年12月对丙公司的投资占该公司10%的股份，2000年度丙公司实现净利润金 8000000元(丙公司的所得税税率为33%)，并在12月份宣告将当年实现净利润的60%向股东分配利润。甲公司对乙公司的股权投资采用权益法核算，对丙公司的股权投资采用成本法核算。
(2)2000年12月31日甲公司应收账款余额为8000000元，会计核算上已按账龄分析法计提坏账准备80000元。按税法规定，坏账准备应按期末应收账款余额的5%计提。
(3)2000年12月31日甲公司存货账面实际成本为8660000元，期末可变现净值为 8600000元，期末存货按成本与可变现净值孰低法计价。
(4)甲公司1996年12月开始交付使用的某项固定资产，其原价为960000元，预计使用年限为5年，预计净残值为零。对该项固定资产，会计核算上采用年数总和法计提年折旧，而按税法规定应按直线法计提年折旧。
(5)甲公司2000年度取得的投资收益中，包括有100000元的国库券利息收入，50000元的企业债券利息收入。
(6)甲公司经核定的全年计税工资总额为500000元， 2000年实际发放的工资为 540000元(不考虑工会经费、职工福利费和职工教育经费)。
(7)甲公司2000年度的营业外支出中，有100000元直接捐赠给贫困地区某单位。
根据上述资料，回答下列各题。

如果甲公司2000年度以前，除了1996年12月交付使用的某项固定资产，其折旧引起时间性差异外，无其他时间性差异事项，则甲公司2000年“递延税款”账户的年初账面余额为( )元。
